Many factors should be considered in the construction of an organic fertilizer plant, such as the market sales of organic fertilizer, the development prospects of the organic fertilizer industry, raw materials for organic fertilizer production, equipment for organic fertilizer production line, and investment in organic fertilizer production line. After the establishment of the plant, when organic fertilizer is put into production, it is necessary to consider the maintenance of organic fertilizer equipment.
After using organic fertilizer production equipment for a period of time, there will inevitably be wear and failure. Organic fertilizer production line needs all machines to work together. Some machine failures will certainly affect the progress of the whole production line. How to reduce equipment wear, production failure and extend the service life of organic fertilizer equipment is particularly important. This paper introduces the matters needing attention and maintenance in the use of organic fertilizer production equipment.
Maintenance of organic fertilizer production process
Organic fertilizer production process mainly includes fermentation, turning, crushing, mixing, granulation, screening, drying, cooling, packaging. Mainly used in organic fertilizer equipment are: compost turning machine, crusher, mixer, granulator, screening machine, dryer, cooler, packing machine.
From the point of view of organic fertilizer production process, the maintenance methods of several important machines are mainly introduced.
Compost turning machine
After use, remove the residues and residues from the machine and the surrounding sites, and add lubricants to the lubrication points. Check the oil quantity of the gearbox and fill it with enough gear oil. Clean up the accumulated material in the lower outlet and keep it unblocked. Check the contact condition of contactors in the electronic control cabinet. If there is any damage, replace it immediately.
Before using the crusher, it is necessary to check whether the shape of the crusher is damaged and whether all parts are complete. Before the mill is connected to the power supply, please confirm whether there is any iron foreign body in the mill and rotate the flywheel manually for more than one circle. It is absolutely forbidden to move the movable knife by hand to ensure safety. Make sure that the grinder's main engine is steered correctly, then the motor can be started and put into production.
The internal cutters of the crusher have different use time. If there is wear and tear, please change the blade in time. When installing the cutter, the rotary cutter must be tightened. The mill runs for about 500 hours. Please check the left and right main bearings, clean them if necessary, and lubricate them. The grinder has a heavy workload. It is necessary to check the belt tightness of the drive triangle regularly to ensure the smooth and reliable transmission of the movable knife.
The rotational speed of the crusher can not be increased at will. When the crusher works with a larger power machine, attention should be paid to controlling the flow and making the flow uniform.
Before starting, check all bolts loose. No big stones or iron blocks can be carried in the mixing material to avoid damaging the mixing blades. Check whether the oil surface in the bearing seat and reducer is in place.
During the operation of the screen, the wear condition should be checked regularly to see if there is leakage due to local wear on the screen surface, and if there is excessive deformation due to the wear of the screen hole on the screen surface, thus affecting the classification accuracy and screening efficiency. In case of the above situation, the machine should be shut down and repaired, and the parts with excessive wear should be given the root number.
The uniformity of feed and moisture content of raw materials should be ensured in normal production. Stop feeding before shutdown, and wait for the material in the body to be basically discharged before shutdown. When necessary, the machine can be opened for 2-3 minutes after stopping, and all the materials in the body can be pushed out. If the machine is stuck or the power load is too large to pull, it is necessary to reduce the material supply and stop checking in time, and clean up the inner wall of the machine.
When the air supply is not stopped, it is forbidden to add fuel to the furnace to avoid scratches. When the dryer is running, it is forbidden to remove the protective device. When inspecting stoves and dryers, it is forbidden to use mobile lamps with voltage higher than 12 volts.
1. Do not shut down frequently to avoid overload operation of organic fertilizer equipment.
2. The tyres of new equipment are prone to loosening, so it is necessary to check them frequently.
3.Check the operation of each motor reducer, if there is abnormal noise, fever and other conditions should be immediately stopped for inspection.
4.Check the wear condition of each bearing and replace the excessive wear. Bearing oil temperature rise, should immediately stop operation, check the reasons.
5.Check whether the chain is loose, damaged and aging.
6.If it is necessary to stop production, the residual organic fertilizer raw materials in the equipment should be cleaned out, so as to avoid the residues remaining in the equipment to aggravate the corrosion of the equipment, and do a good job of cleaning, moisture-proof and anti-corrosion. Every 1 - 2 days after shutdown, the equipment will be idled for 10 - 20 minutes, so that it can be used normally when it is put into production again.
After installation, commissioning and acceptance of an organic fertilizer production line, there will be no major problems in the basic operation mechanism and procedures of the equipment. In order to make the equipment meet the production demand continuously and steadily, it is necessary to strictly implement the use requirements of the equipment and do well in daily maintenance so as to better guarantee the efficiency and service life of the equipment and gain greater economic benefits for the manufacturer.
