2. The installer should be familiar with the installation requirements of each equipment and strictly follow the technical requirements for construction.
3. The equipment may cause deformation, damage or loss during transportation. Therefore, before installation, check and check the equipment list, and take corresponding measures to ensure that the equipment is in good condition before installation.
4. Before each equipment enters the installation site, it shall be numbered, and the installation process flow card and schedule shall be formulated. According to the requirements of the installation process sequence, the equipment shall be transferred to the site for installation.
5. Installation sequence: From top to bottom, install the connecting pipes and electrical equipment after the host equipment and the rack are in place.
6. Install the required tools: Equipment and materials must be available.
7. After the installation, the rotating parts of the equipment must be flexible and free from card, bump and impact. The connecting parts must be firm and sealed, and there must be no leakage, air leakage or oil leakage.
8. The installation of electrical equipment shall comply with the relevant national regulations. The direction of each line shall be clear, and there shall be no running or leakage of electricity. Wires and cables shall have protective casings to prevent rat bites.
9. After all the equipments have been installed, each single unit should be tested for empty vehicles, and the normal operation can be put into the load test.
10. Before the load test, the electronic batching scale and the packing scale are calibrated to achieve the specified accuracy.
11. The load is running for 8h, and it can be delivered to the factory for production without trouble.
Second, the operation and use of
1. Check the equipment by the staff on duty at each position before driving.
(1) Whether or not foreign matter falls into the equipment; whether the rotating parts are flexible, whether there is a card or a collision phenomenon; whether the connecting parts are firm; whether there are leakage powder, air leakage, oil leakage, etc. If there is a fault, it should be eliminated in time.
(2) Whether the gears have lubricating oil; whether the tension of the transmission belt is suitable; whether the hammer of the crusher, the die of the granulator and the pressure roller need to be replaced; whether the specifications of the sieve meet the requirements.
2. Control room personnel should master the daily production schedule and the storage of the main and auxiliary materials in order to schedule production.
3 Operation sequence
(1) Close the main power switch first, then place each system switch to the working position.
(2) Turn on the audio signal switch to notify each staff member to enter the job.
(3) After completing all preparatory work, the control room duty personnel determine the entry number of each material, and divide each three-way valve to each corresponding position, first start the dust removal fan, and then turn on the switches according to the processing sequence.
(4) The control room duty personnel should always pay attention to observe various signal lights on the analog screen. If the batch warehouse sends out empty or full warehouse signals, the relevant loading personnel should be notified in time to operate the silo gate.
(5) The staff should, according to the production schedule, recall the formula for the required materials and use the computer and its auxiliary devices correctly.
(6) When operating the feeding device of the pulverizer and granulator, ensure that the main motor operates at rated current without clogging.
(7) All kinds of trace elements, vitamins, etc., from the additive inlet of the mixer, quantitatively input, the mixer mixes a batch of materials, feed once, the input time is the beginning of each batch of materials, the control room Give input signals and invest in time.
Third, maintenance and repair
1. Perform maintenance and care as required by the instruction manual for each equipment. If there is no special requirement, the bearing injection oil adopts ZG-3 calcium-based lubricating oil, the reducer lubricating oil adopts HJ-60 mechanical oil, and in winter, if the room temperature is lower than -10 °C, HJ-20 mechanical oil is used.
2. The equipment should be repaired once in half a year and overhauled within one year. Replace the lubricant, clean the bearings, and replace the damaged parts during minor repairs.
3. Adjust the tightness of the belt in time. The belt must not have severe slippage when the machine is running.
4. The damaged parts such as the hammer and sieve of the pulverizer, the stamper of the granulating system and the pressure roller shall be repaired, adjusted and replaced in time. Replacement, repair, and adjustment time, depending on the productivity of the feed processing product or the quality of the product, generally when the productivity is significantly reduced, the pellet forming rate and the surface quality are not required, it should be adjusted or replaced in time.
5. After the hammer of the crusher is worn, it should be reversed or turned over. When the head is turned, the original hammer arrangement should be maintained. When all four corners are worn and need to be replaced with new hammers, each set of new hammers should be weighed. The weight difference of each set of hammers should not exceed 5g. It must be assembled according to the hammer arrangement diagram during installation to avoid strong crusher. shock.
6. After using the electronic scale for half a year, it is necessary to check and calibrate its accuracy.
7. After each shift, the residue in the die hole should be flushed out of the mold cavity with the bean cake powder.
8. The computer control room is always kept clean and quiet.
Fourth, the general failure and troubleshooting method
1. The pulverizer is strongly vibrated and the noise is very high. The reason may be:
(1) The hammers are not arranged correctly, and the hammers should be re-installed according to the hammer arrangement diagram;
(2) Individual hammers are not opened in the pin and should be disposed of in time;
(3) The fixing bolt of the crusher bearing seat is loose or the bearing is damaged, and it should be repaired or replaced in time.
(4) After the pulverizer hammer or the self-contained fan impeller wears, the balance of the rotor is destroyed. At this time, the relevant parts should be replaced in time.
If the inspection is not the above reason, it may be two sets of hammers on the corresponding pin shaft of the pulverizer. If the weight difference is too large, the corresponding two sets of hammers should be re-matched so that the weight difference does not exceed 5g.
2. The pulverizer feeding port returns to the gray
Generally, due to the excessive feeding amount, the lifting capacity of the pulverizer fan is insufficient, and the sieve piece and the suction pipe are blocked. At this time, the material in the upper and lower chambers of the sifter should be shut down in time to clear the suction pipe and re-adjust the feed amount of the pulverizer.
3. There is an abnormal sound in the crusher.
Generally, there is a large piece of hard material entering the pulverizer, or the parts inside the machine are shed and the water is flowing in the pulverizing chamber. Immediately after discovering this condition, stop the machine and inspect the crushing chamber and remove foreign matter.
4. Finished batch materials are too coarse
Generally, the sieve is damaged by abrasion or foreign matter, and holes are caused to cause sifting or improper installation of the sieve, and the gap between the sieve and the sieve edge is not strict. It should be handled accordingly.
5. Mixer fluidity is poor and mixing uniformity is not enough
This may be due to damage to the broken arch in the mixer or the drive belt being too loose. Check the position of the broken arch or the tightness of the drive belt in time.
6. Excessive dust in the operation area
Mainly because the dust bag is not tightly closed, the interface of the conveying pipe and the upper cover of the mixer are not tightly sealed, resulting in leakage of ash. In addition, the fan casing, the conveying pipe elbow and the suction pipe may wear out after using for a period of time. Holes cause ash leakage. Therefore, if too much dust is found, the above parts should be inspected and treated in time.
7. Motor powerlessness and overheating
The motor weakness may be due to a phase disconnection in the three-phase circuit of the motor. The overheating of the motor may be due to short circuit or long-term overload operation of the motor. At this time, stop the machine in time, ask the electrician to check the electrical equipment or adjust the workload.
8. The reason why the pellet machine does not discharge may be:
(1) The feed inlet and the agitator are blocked, and the blockage should be removed in time;
(2) The die hole is blocked, and the die hole should be opened;
(3) The moisture content of raw materials is too high or too low, the amount of steam should be adjusted;
(4) The gap between the die and the press roller is too large, and the gap should be adjusted to meet the requirements.
