This garbage disposal machine only processes and does not recycle kitchen waste. The processing procedures of the grinding disc type kitchen waste disposal machine are as follows:

(1) Installation: When it is used in conjunction with a pool, when installing a garbage disposal machine, the sealing plug must be unscrewed, and the feed pipe is directly sealed with the water outlet of the pool; or when it is not used in conjunction with a pool, no installation is required;

(2) Feeding: When used in conjunction with a pool, the maximum diameter of the kitchen waste material cannot exceed the outlet aperture of the pool. Put the kitchen waste directly into the pool, and at the same time turn on the tap above the pool to fill the garbage disposal machine with water. When disposing of garbage beside the water, you can also add vegetable washing water. The amount of water added should not exceed the height of the water outlet of the pool. Vegetable and fruit waste, meat waste, and spoiled food waste have large differences in size and can be placed directly in the pool; kitchen waste It should be initially processed to less than 35mm, put into the pool, and then automatically flow into the upper inner space of the crushing layer, that is, the feeding layer;

Feeding: When not used in conjunction with the sink, open the top cover, put kitchen waste directly in the upper space of the crushing basket, fill the inner cavity with vegetable washing water or tap water, close the top cover, and then start to dispose of kitchen waste;

(3) Crushing: The granular garbage that does not meet the requirements moves to the edge of the crushing basket under the action of centrifugal force, and the lower large-particle garbage is vigorously collided by the three collision blocks; The 5 toothed ring-cutting collision knives are smashed into small particles smaller than 6mm. The crushing process does not limit the size of the final particles, and it can be crushed as small as possible; the maximum centrifugal force will be slightly larger than 6mm. The knife-like discharge hole on the side wall of the crushing basket is cut into 6mm particles before it can pass the screening of the crushing layer and enter the grinding disc layer; according to the normal operation for 3-10 minutes, after the stirring and collision in the crushing basket reaches a certain particle size requirement, it will be removed from the knife sample. The discharge hole is discharged and flows to the feed layer on the upper part of the upper grinding disc. The size of the garbage particles is controlled by the diameter of the 6mm ballast hole. The large particle garbage that cannot meet the requirements will not flow out of the crushing basket until it fully meets the requirements. ;

(4) Grinding: The small particle garbage less than 6mm processed by the crushing layer flows into the extrusion grinding area of the upper grinding disc from the feeding layer and the feeding hole of the upper grinding disc; when the lower grinding disc rotates, it flows out from the slurry hole A. The slurry waste is cut and pulverized for the last time; the grinding disc layer and the grinding layer run asynchronously, and the upper grinding disc is a fixed body, which is further reduced after being processed by the extrusion and grinding area, and gradually squeezed to the small gap cutting and grinding area for small gap cutting. Grinding, and finally reach the cutting and grinding area without gaps. The reverse cutting grooves of the upper and lower grinding discs cut and grind the garbage particles into a slurry-like flow juice, and the cutting juice is discharged from the slurry discharge hole B to the waste discharge layer; during operation, the grinding The effect is not affected by the hardness of the particles. Because the upper and lower grinding discs cannot move up and down, the harder the particles are, the pressure on the fixed disc will automatically increase, and the harder particles will be squeezed, ground, cut and crushed; The grinding speed cannot be the same as the rotation speed of the pulverizing layer. The speed of the lower grinding disc is only 900 rpm under the action of the reduction gear, and the maximum grinding speed is only 4.47m/s;

(5) Discharge: Open the discharge solenoid valve, the slurry fluid waste flowing out from the discharge hole A of the lower grinding plate is cut by the discharge hole B on the edge of the gear fixing plate, and flows from the discharge hole B into the discharge oblique. On the plate, the slurry discharge swash plate flows through the cylinder hole. When the solenoid valve is opened, the slurry flows from the through hole on the solenoid valve, through the connecting pipe of the slurry outlet, and is discharged to the sewer; it can be realized by adjusting the slurry solenoid valve. The waste slurry is discharged without stopping; the slurry discharge solenoid valve can be automatically controlled according to the required amount. The feed hole of the upper grinding disc flows into the small particle waste flow of the extrusion grinding zone of the upper grinding disc.

For larger kitchen waste, you can directly open the top cover, put the garbage into the crushing basket with a diameter of 200mm, then cover the top cover, connect to the outlet pipe of the pool, and start the normal operation to dispose of kitchen waste; For the very small amount of rubbish with large particles of hard bones, the maintenance cover is regularly opened to manually remove the crushing basket, and it is treated as wet garbage classification garbage. This machine does not bear the crushing treatment of unprocessed large hard bones.

When the pool is used as the feed storage of the garbage disposal machine, due to the large feeding hole of the pool, hard objects such as spoons may be mixed into the crushing layer of the garbage disposal machine, causing damage to the garbage disposal machine. After turning on the machine, if there is an abnormal sound, stop the machine immediately, open the maintenance cover to take out the foreign object, and then open the maintenance cover tightly and then turn on the machine. Generally, foreign objects that can enter the garbage disposal machine will not cause damage to the processor, and may not hear any abnormality. Therefore, after a week of use, the maintenance cover should be opened to check whether there are foreign objects stored in the processor; if the feeding is strictly controlled, it is not necessary to open the maintenance cover to check.

Working principle: For kitchen waste of different shapes and hardness such as long-fiber vegetables, thick-skinned melons and fruits, flesh-skinned animal bones, shrimp-skinned crab shells, etc., it adopts stirring, collision, cutting, grinding disc grinding, etc., to carry out strong force in the state of water retention and supply. It is crushed into a slurry and diluted, and then discharged into the municipal sewers immediately; the height of this garbage disposal machine is just placed at the lower part of the pool, and the kitchen waste is directly crushed and then discharged to the municipal sewers, which reduces the storage, classification and delivery of kitchen waste. It can reduce the pressure of public municipal administration on garbage disposal, and effectively prevent the chronic clogging of municipal sewage pipes, internal corrosion and other safety hazards. In the process of kitchen waste disposal, the processor has a water limit control system, which effectively It solves the problem that the crushed garbage is difficult to discharge without water.
