Description

Technical Field

[0001] The present invention relates to a kitchen waste treatment machine and a treatment method thereof, and in particular to a grinding disc type kitchen waste treatment machine and a treatment method thereof, which is suitable for the classification and treatment technology of kitchen waste in households, canteens and restaurants, and belongs to the environmental protection field of waste classification treatment technology. Background Art

[0002] Kitchen waste refers to perishable organic waste such as fruit and vegetable and food scraps, leftovers, melon and fruit peels discarded in daily household life. It has the characteristics of high water content, high salt and oil content, and is not suitable for landfill or incineration.

[0003] At present, all countries are moving towards the direction of reducing, recycling and harmless treatment of kitchen waste. Since the design load of my country's municipal sewage pipe network and treatment system does not take kitchen waste into consideration, if this method is used, it will cause pipe network blockage, increase the water volume and water quality load of sewage treatment plants, and even internal corrosion of the pipe network will produce methane, which may cause explosion risks. The key problem is that the garbage particles after being processed by the kitchen waste crusher are too large, which is easy to cause pipe network blockage. Only in the blocked state can internal corrosion or methane be produced. Therefore, the development of kitchen waste treatment machines suitable for use in the Chinese environment has become an important issue in solving the difficulty of garbage sorting and treatment. Summary of the invention

[0004] The purpose of the present invention is to provide a grinding disc type kitchen waste treatment machine to solve the problem that the garbage particles after being processed by the kitchen waste crusher are too large and easily cause pipe network blockage in the above-mentioned prior art, so as to achieve the development of kitchen waste in the direction of reduction, resource utilization and harmlessness, and to develop a grinding disc type kitchen waste treatment machine to collide and grind the kitchen waste into a slurry-like diluted juice suitable for discharge to the Chinese municipal sewage system for treatment.

[0007] The main body also includes a feeding layer, a crushing layer, a grinding disc layer and a garbage discharge layer; the crushing layer is a rotating layer, including a crushing basket, 4 toothed crushing knives, 3 collision blocks, 5 ring-cutting collision knives, a number of knife-like discharge holes, fixing screws A and fixing screws B; the crushing layer is the initial processing layer for kitchen waste, requiring the kitchen waste to be processed to a particle fluid with a maximum garbage diameter of no more than 6mm, and kitchen waste with a diameter of less than or equal to 6mm can enter the upper grinding disc storage area for extrusion, grinding and shearing;

[0008] The feeding layer includes a feeding pipe and a garbage storage area, and the garbage storage area is the internal space at the top of the crushing layer; the crushing basket is a rotating part, installed in the cylinder and below the feeding layer, and the rotation speed of the crushing basket is 2500-5000 rpm; 4 toothed crushing knives, 3 collision blocks and 5 ring-cutting collision knives are all in the crushing basket; the 4 toothed crushing knives have upper and middle different levels and are installed in the middle of the crushing basket, and the 4 toothed crushing knives include 2 symmetrically arranged toothed core crushing knives and 2 symmetrically arranged toothed side crushing knives, which respectively perform stirring collision, cutting and crushing treatment on the kitchen waste wet garbage inside and outside the core of the crushing basket; the toothed core crushing knives are arranged vertically upward, and the toothed side crushing knives are arranged obliquely, and the angle between the toothed side crushing knives and the horizontal plane is 30-35°;

[0009] Three collision blocks are arranged on the inner side of the edge of the crushing basket and fixed to the bottom of the crushing basket by fixing screws B; five ring-cutting collision knives are fixedly arranged on the inner edge of the crushing basket frame, and a number of knife-like discharge holes are arranged on the wall of the crushing basket frame, and the diameter of the knife-like discharge holes is 4.5-7.5mm; the knife-like discharge holes are actually the discharge holes that are not inverted and blunted. When the garbage residue larger than the hole diameter is discharged from the hole, it is squeezed, cut and crushed by the knife holes due to the centrifugal force before it can be discharged through the discharge holes; for the fluid, as long as there is extrusion, the fluid will redirect to all channel holes;

[0010] The upper end of the transmission shaft is provided with a square positioning key, which is square and has four sides tightly fitted with the crushing basket, so that when the transmission shaft rotates, the crushing basket is driven to rotate, and when the crushing basket rotates, the three collision blocks and the five ring-cutting collision knives are driven to rotate; the bottom center hole is tightly fitted with four toothed crushing knives and fixedly connected to the square positioning key at the upper end of the transmission shaft through fixing screws A; a fixing thread is provided in the lower end of the transmission shaft, and the output shaft of the motor is fixedly connected to the lower end of the transmission shaft through the fixing thread;

[0012] The centrifugal force plus the gravity feeding of garbage and water is adopted; the upper grinding disc grinding surface at the lower end surface of the upper grinding disc is designed with a grinding cutting groove A, the width of the grinding cutting groove A is 5-9mm, and the depth is 4-6mm; the lower grinding disc grinding surface at the upper end surface of the lower grinding disc is designed with a grinding cutting groove B opposite to the upper grinding disc, the width of the grinding cutting groove B is 5-9mm, and the depth is 4-6mm;

[0013] The grinding surface of the upper grinding disc is distributed with an extrusion grinding area and a cutting grinding area from the inside to the outside. The part of the cutting grinding area close to the extrusion grinding area is a small gap cutting grinding area, and the part on the outside is a gapless cutting grinding area; the grinding gap between the upper grinding disc and the lower grinding disc is a fixed gap, which is determined by the positioning of the stepped transmission shaft. The gap between the upper and lower grinding discs is controlled at 0.1-1.5mm. The lower concave part of the lower grinding disc is a gear pit, and more than 20 pulp discharge holes A are evenly arranged at the edge of the lower grinding disc; the transition gear is arranged in the gear pit, and the size of the transition gear matches the size of the gear pit, reducing the shaft speed from 3000 rpm to 900 rpm; the grinding disc adopts the design of reducing the diameter of the grinding disc, increasing the strength of the grinding disc and the speed reduction of the gear. The maximum diameter of the grinding disc is 190mm and the maximum linear speed is 4.47m / s. The motor speed is designed to be 2500-5000 rpm, and the grinding disc speed is only 900 rpm;

[0014] The garbage discharge layer includes a gear fixing plate, a slurry discharge inclined plate, a slurry discharge solenoid valve and a slurry discharge port. The gear fixing plate is arranged below the lower grinding plate and can play the role of fixing the transition gear. More than 20 slurry discharge holes B are evenly arranged at the edge of the gear fixing plate; the angle between the upper and lower sides of the slurry discharge inclined plate is 3-5 degrees; the slurry discharge solenoid valve is externally connected to a slurry discharge pipe and automatically opens when slurry discharge is required; when the lower grinding plate rotates, the slurry garbage is cut and crushed, and the cut slurry is discharged from the slurry discharge hole B to the garbage discharge layer; the garbage juice flows directly from the slurry discharge port and the external slurry discharge pipe to the municipal sewer through the slurry discharge solenoid valve; the slurry discharge hole A and the slurry discharge hole B are both blunted, and when the garbage residue larger than the aperture is discharged from the slurry discharge hole A and the slurry discharge hole B, it can only be discharged through the discharge hole after being squeezed, cut and crushed by the knife hole due to the centrifugal force; for the fluid, as long as there is extrusion, the fluid will redirect to flow to all channel holes;

[0015] Since the diameter of the juice fluid flowing out of the kitchen waste disposer is less than 6mm in the first stage, it has reached the leakage hole of a general kitchen sink and has no danger of clogging the municipal sewage pipe network. After being squeezed, ground and cut by the grinding disc layer, the granular garbage has reached the sweating particle size of soybean milk level and is unlikely to cause clogging of the sewer;

[0016] A downward cylindrical seat is arranged in the middle of the upper cover, and the feed pipe is arranged in the cylindrical seat. The feed pipe is a retractable nylon feed pipe, and the product model is SYQ-42.5 nylon bellows. The feed pipe is threadedly connected to the inner wall of the cylindrical seat, and the sealing plug is arranged above the cylindrical seat and threadedly connected. The water pool is the garbage storage device of the garbage disposal machine, and the water outlet diameter of the water pool is 40mm.

[0017] The height of the main part of the garbage disposal machine is 305mm and the maximum diameter is 250mm.

[0018] The diameter of the knife-like discharge hole is 6mm, and the rotation speed of the crushing basket is 3000 rpm; there are 2 symmetrical toothed core crushing knives and 2 toothed side crushing knives, which respectively perform stirring, collision, cutting and crushing processing on the wet kitchen waste inside and outside the core of the crushing basket; the 2 toothed core crushing knives are arranged vertically upward, and the blades of the 2 toothed core crushing knives are arranged in reverse; the 2 toothed side crushing knives are arranged obliquely, and the blades of the 2 toothed side crushing knives are arranged in reverse, and the angle between the toothed side crushing knives and the horizontal plane is 32°.

[0019] The grinding plane of the upper grinding disc is divided into 8 sectors, and the angle between the directions of the grinding cutting grooves A of every two adjacent sectors is 45°; the center of the lower upper surface of the lower grinding disc is the transmission shaft hole, and the grinding plane around the transmission shaft hole is divided into 8 sectors, and the angle between the directions of the grinding cutting grooves B of every two adjacent sectors is 45°;

[0020] 32 pulp discharge holes A are evenly arranged on the edge of the lower grinding disc, the eccentricity of the feed hole of the upper grinding disc is 38mm, the width of the grinding and cutting groove A is 8mm and the depth is 5mm, the width of the grinding and cutting groove B is 8mm and the depth is 5mm; the gap between the upper and lower grinding discs is controlled at 1mm, and the upper and lower grinding discs are both formed by thick steel plates.

[0021] 32 slurry discharge holes B are evenly arranged on the edge of the gear fixing plate, and the angle between the upper and lower parts of the slurry discharge inclined plate is 4 degrees; the automatic control system mainly controls the slag discharge flow rate of the slurry discharge solenoid valve to ensure that the storage water level inside the cylinder is not lower than the height of the crushing basket, and the water level cannot be higher than the top of the cylinder inner cavity.

[0022] The motor used is a DC motor with a power of 200-300w and a speed of 3000 rpm;

[0023] The motor power is transmitted to the various components of the crushing layer and the lower grinding disc through the transmission shaft, so that the crushing basket of the crushing layer and the transmission shaft that realize the garbage crushing function are stepped and fastened with screws; the lower grinding disc of the grinding disc layer and the transmission shaft are positioned with square positioning keys, and there is no upward or downward movement clearance except in the direction of rotation; the stepped positioning of the lower grinding disc and the transmission shaft has a force-increasing effect on the extrusion, grinding and cutting processing, and the gear set reduction connection has a decompression effect on the extrusion, grinding and cutting processing.

[0024] This garbage disposal machine only processes and does not recycle kitchen waste. The processing procedure of the grinding disc kitchen waste disposal machine is as follows:

[0025] (1) Installation: When the garbage disposal machine is used in conjunction with a pool, the sealing plug must be unscrewed and the feed pipe must be directly and tightly connected to the water outlet of the pool; or when it is not used in conjunction with a pool, no installation is required;

[0026] (2) Adding materials: When used in conjunction with a sink, the maximum diameter of the kitchen waste material cannot exceed the water outlet diameter of the sink. Put the kitchen waste directly into the sink and turn on the tap above the sink to fill the garbage disposal with water. You can process the garbage while draining the water or add vegetable washing water. The amount of water added should not exceed the height of the sink outlet. Vegetable and fruit waste, meat waste, and rotten food waste vary greatly in size and can all be placed directly in the sink. Kitchen waste should be initially processed to less than 35 mm and put into the sink, and then automatically flow into the upper internal space of the crushing layer, i.e., the feeding layer;

[0027] Adding materials: When not used with a sink, open the upper cover, put the kitchen waste directly into the upper space of the crushing basket, fill the inner cavity with vegetable washing water or tap water, close the upper cover, and start the machine to process the kitchen waste;

[0028] (3) Crushing: Under the action of centrifugal force, the waste particles that do not meet the requirements move toward the edge of the crushing basket. The large waste particles at the bottom are strongly collided by three collision blocks. The medium and small waste particles floating in the middle and upper parts are crushed into small waste particles less than 6 mm by five toothed ring-cutting collision knives on the inner wall of the crushing basket. The crushing process does not limit the size of the final waste particles, and any size can be crushed. The maximum centrifugal force will cut the waste particles slightly larger than 6 mm into 6 mm particles by the knife-like discharge holes on the side wall of the crushing basket, and then they can pass through the screening of the crushing layer and enter the grinding disc layer. After 3-10 minutes of normal operation, after the mixing and collision in the crushing basket reaches a certain particle size requirement, it will be discharged from the knife-like discharge holes and flow to the feed layer on the upper part of the upper grinding disc. The size of the waste particles is controlled by the 6 mm diameter discharge hole. The large waste particles that do not meet the requirements cannot flow out of the crushing basket until they fully meet the requirements and can flow to the lower level for processing.

[0029] (4) Grinding: small particles of garbage less than 6 mm processed by the crushing layer flow from the feed layer and the feed hole of the upper grinding disc into the extrusion grinding area of ​​the upper grinding disc; when the lower grinding disc rotates, the pulp garbage flowing out of the pulp discharge hole A is cut and crushed for the last time; the grinding disc layer and the crushing layer operate asynchronously, the upper grinding disc is a fixed body, which becomes smaller after being processed in the extrusion grinding area, and is gradually squeezed to the small gap cutting and grinding area for small gap cutting and grinding, and finally reaches the gapless cutting and grinding area, the reverse cutting grooves of the upper and lower grinding discs cut and grind the garbage particles into pulpy juice, and the cut pulp is discharged from the pulp discharge hole B to the garbage discharge layer; during operation, the grinding 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 greater the pressure of the fixed disc will be, and even the hardest particles will be squeezed, ground, cut and crushed; the cutting and grinding speed of the upper and lower grinding discs cannot be the same as the rotation speed of the crushing layer. The speed of the lower grinding disc is only 900 rpm under the action of the reduction gear, and its maximum grinding speed is only 4.47 m / s;

[0030] (5) Discharge: Open the discharge solenoid valve, and the slurry and fluid garbage flowing out from the discharge hole A of the lower grinding plate will be cut by the discharge hole B on the edge of the gear fixed plate, and then flow into the discharge inclined plate from the discharge hole B, and flow through the cylinder hole along the discharge inclined plate. When the solenoid valve is opened, the slurry flows from the through hole on the solenoid valve, through the connecting pipe of the discharge port, and is discharged into the sewer; the slurry discharge solenoid valve can be adjusted to discharge garbage slurry without stopping the machine; the slurry discharge solenoid valve can be automatically controlled according to the required amount, and the adjustment of the slurry discharge solenoid valve can control the discharge amount, and at the same time adjust the discharge amount of small-particle garbage from the knife-like discharge hole on the side wall of the crushing basket, and the flow rate of small-particle garbage flowing into the extrusion grinding area of ​​the upper grinding plate from the feed hole of the upper grinding plate.

[0031] For larger kitchen waste, you can directly open the top cover and put the waste into a crushing basket with a diameter of 200mm. Then close the top cover, connect it to the water outlet pipe of the pool, and start the machine normally to process the kitchen waste. For the very small amount of hard bone large particles that cannot be crushed for a long time, open the maintenance cover regularly to manually remove them from the crushing basket and treat them as wet garbage classification. This machine is not responsible for the crushing of unprocessed large hard bones.

[0032] When a water pool is used as the feed storage device of the garbage disposal machine, due to the large feed hole of the water pool, hard objects such as a spoon may be mixed into the crushing layer of the garbage disposal machine, causing damage to the garbage disposal machine. After starting the machine, if there is an abnormal sound, the machine should be stopped immediately, the maintenance cover should be opened to remove the foreign object, and then the maintenance cover should be opened and restarted; generally, foreign objects that can enter the garbage disposal machine will not cause damage to the processor, and abnormal sounds may not be heard. Therefore, after one week of use, the maintenance cover should be opened to check whether there are any foreign objects stored in the processor; if the feeding is strictly controlled, it is not necessary to open the maintenance cover for inspection.

[0033] Working principle: For kitchen waste of different shapes and hardness, such as long-fiber vegetables, thick-skinned fruits and vegetables, meat skins and animal bones, shrimp skins and crab shells, stirring, collision, cutting, and grinding are used to crush them into a slurry and dilute them while maintaining water supply, and then immediately discharged into the municipal sewer; the height of this garbage disposal machine is just right to be placed at the bottom of the pool, and the kitchen waste is directly crushed and discharged into the municipal sewer, reducing the storage, classification, and delivery of kitchen waste to garbage stations, reducing the pressure of public municipalities on garbage disposal, and effectively preventing the chronic blockage and internal corrosion of municipal sewage pipes caused by kitchen waste; in the process of kitchen waste treatment, this processor has a water limit control system, which effectively solves the problem of difficult discharge of crushed garbage without water.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] (1) No blockage: The grinding disc kitchen waste disposer adopts a two-layer garbage crushing technology. The maximum diameter of the garbage particles processed by the crushing layer is 6mm, which has reached the requirements of the filter aperture of the general kitchen sink. The kitchen waste processed by the grinding disc layer can reach the slurry fluid, ensuring the flow rate of the treated garbage in the sewer, and will not cause sedimentation-type chronic deterioration and blockage, and eliminate the risk of internal corrosion of the pipe network to produce methane and explosion. The grinding disc kitchen waste disposer has water level control and automatic adjustment of slurry flow, and will not cause dry garbage operation and garbage blockage. It is suitable for operation and use by the elderly in the family;

[0036] (2) Immediate processing: Kitchen waste is the wet waste that is processed by Shanghai garbage classification. This type of waste is very easy to deteriorate. Some wet waste is already in a deteriorated state and is itself a pollutant that must be processed in a timely manner. The longer this type of polluted waste is stored, the more serious the pollution to the environment. The grinding disc kitchen waste treatment machine can promptly process the kitchen waste that may deteriorate and reduce the degree of pollution to the environment caused by wet waste. Kitchen waste can be processed immediately, which is an effective helper for kitchen hygiene.

[0037] (4) High crushing efficiency: The crushing disc kitchen waste disposer can be directly installed under the kitchen sink to discharge kitchen waste directly and safely. It is easy to install, does not occupy additional kitchen space, and creates a good environment. The crushing disc kitchen waste disposer processes garbage in two layers, but only has one energy-saving motor, which saves electricity and energy. The crushing disc kitchen waste disposer has a simple structure, can be operated continuously, has high crushing efficiency, and can be developed into a series of machines. It is not only suitable for families, but also for restaurants and collective canteens.

[0038] (5) Easy maintenance: The processor has a maintenance port on the side wall of the first-stage crushing disk. Large foreign objects such as a spoon may enter the processor together with kitchen waste. When an alarm sounds during the operation of the processor, the maintenance door can be opened to remove the foreign objects. BRIEF DESCRIPTION OF THE DRAWINGS

The cutting grinding area is a small gap cutting grinding area near the extrusion grinding area, and the cutting grinding area on the outside is a gapless cutting grinding area. The grinding gap between the upper grinding disc 801 and the lower grinding disc 802 is a fixed gap, which is determined by the positioning of the stepped transmission shaft 502. The gap between the upper and lower grinding discs 802 is controlled at 0.1-1.5mm. The lower concave part of the lower grinding disc 802 is a gear pit. More than 20 pulp discharge holes A are evenly arranged at the edge of the lower grinding disc 802. 808; the transition gear 803 is arranged in the gear pit, the size of the transition gear 803 matches the size of the gear pit, and the shaft speed is reduced from 3000 rpm to 900 rpm; the grinding disc adopts the design of reducing the grinding disc diameter, increasing the grinding disc strength and gear speed reduction, the maximum diameter of the grinding disc is 190mm and the maximum linear speed is 4.47m / s, the speed of the motor 501 is designed to be 2500-5000 rpm, and the grinding disc speed is only 900 rpm;

[0072] Since the diameter of the juice fluid flowing out of the kitchen waste disposer is less than 6mm in the first stage, it has reached the leakage hole of the general kitchen sink 3 and has no danger of clogging the municipal sewage pipe 1 network. After being squeezed, ground and cut by the grinding disc layer 8, the granular garbage has reached the sweating particle size of soybean milk level and is unlikely to cause clogging of the sewer;

[0075] like Figure 4-1 to Figure 5-2 As shown, the diameter of the knife-like discharge hole 705 is 6 mm, and the rotation speed of the crushing basket 701 is 3000 rpm; there are 2 symmetrical toothed core crushing knives 702 and 2 toothed edge crushing knives 702, which respectively perform stirring, collision, cutting and crushing treatment on the kitchen waste inside and outside the core of the crushing basket 701; the 2 toothed core crushing knives 702 are arranged vertically upward, and the blades of the 2 toothed core crushing knives 702 are arranged in reverse; the 2 toothed edge crushing knives 702 are arranged obliquely, and the blades of the 2 toothed edge crushing knives 702 are arranged in reverse.

[0076] like Figures 7-1 to 8-4 As shown, the grinding plane of the upper grinding disc 801 is evenly divided into 8 sectors, and the angle γ between the directions of the grinding cutting grooves A 806 of every two adjacent sectors is 45°; the center of the lower upper surface of the lower grinding disc 802 is the transmission shaft hole 804, and the grinding plane around the transmission shaft hole 804 is evenly divided into 8 sectors, and the angle θ between the directions of the grinding cutting grooves B 807 of every two adjacent sectors is 45°;

[0079] like Fig.10 As shown, the motor 501 used is a DC motor 501 with a power of 200-300w and a rotation speed of 3000 rpm;

[0080] The power of the motor 501 is transmitted to the various components of the crushing layer 7 and the lower grinding disc 802 through the transmission shaft 502, so that the crushing basket 701 of the crushing layer 7 and the transmission shaft 502 for realizing the garbage crushing function are stepped and fastened with screws; the lower grinding disc 802 of the grinding disc layer 8 and the transmission shaft 502 are positioned with square positioning keys, and there is no upward or downward movement gap except in the direction of rotation; the stepped positioning of the lower grinding disc 802 and the transmission shaft 502 has a force-increasing effect on the extrusion, grinding and cutting processing, and the gear set reduction connection has a decompression effect on the extrusion, grinding and cutting processing.

[0081] Working process: put the kitchen waste into the water pool 3, add the material, and turn on the tap above the water pool 3 to fill the garbage disposal machine with water. After the water and the material are mixed, they automatically flow into the feeding layer 6; the granular kitchen waste moves to the edge of the crushing basket 701 under the action of centrifugal force, and the large granular waste at the bottom is strongly collided by the three collision blocks 703; the medium and small granular waste floating in the middle and upper parts is cut and collided by the five toothed ring cutting collision knives 704 on the inner wall of the crushing basket 701 into small granular waste less than 6 mm, and is discharged through the knife-like discharge hole 70 5 flows to the feed layer 6 on the upper part of the upper grinding disc 801; then flows into the extrusion and grinding area of ​​the upper grinding disc 801 through the feed hole 805 of the upper grinding disc 801. The upper grinding disc 801 is a fixed body. When the lower grinding disc 802 rotates, the pulp garbage is cut and crushed; after being processed in the extrusion and grinding area, it becomes smaller and gradually squeezed to the small gap cutting and grinding area for small gap cutting and grinding, and finally reaches the gapless cutting and grinding area. The reverse cutting grooves of the upper and lower grinding discs 802 cut and grind the garbage particles into pulp-like juice, and the cut pulp is discharged from the pulp discharge hole A 808 and the pulp discharge hole B 905 to the garbage discharge layer 9; open the pulp discharge solenoid valve 903, and the pulp fluid garbage flowing out of the pulp discharge hole A 808 of the lower grinding disc 802 flows into the pulp discharge inclined disc 902 through the pulp discharge hole B 905. When the solenoid valve is opened, the pulp flows from the through hole on the solenoid valve, through the connecting pipe of the pulp discharge port 904, and is discharged to the sewer.

[0082] This garbage disposal machine only processes and does not recycle kitchen waste. The processing procedure of the grinding disc kitchen waste disposal machine is as follows:

[0083] (1) Installation: Figure 1 As shown, when installing the garbage disposal machine, the sealing plug 401 must be screwed out and the feed pipe 601 is directly and sealedly connected to the water outlet of the pool 3;

[0084] (2) Adding materials: Figures 1 to 3 As shown, the maximum diameter of the kitchen waste material cannot exceed the water outlet diameter of the pool 3. Put the kitchen waste directly into the pool 3, and turn on the tap above the pool 3 to fill the garbage disposal machine with water. The garbage can be processed while the water is discharged, or vegetable washing water can be added. The amount of water added should not exceed the height of the pool outlet 301. The volumes of fruit and vegetable waste, meat waste, and rotten food waste vary greatly, and they can all be placed directly in the pool 3. The kitchen waste should be initially processed to less than 35 mm, put into the pool 3, and then automatically flow into the upper internal space of the crushing layer 7, that is, the feeding layer 6;

[0085] (3) Crushing: Figure 3 to Figure 5-2 As shown, the granular garbage that does not meet the requirements moves to the edge of the crushing basket 701 under the action of centrifugal force, and the large granular garbage at the bottom is strongly collided by the three collision blocks 703; the medium and small granular garbage floating in the middle and upper parts are cut and collided by the five toothed ring-cutting collision knives 704 on the inner wall of the crushing basket 701 into small granular garbage less than 6mm. The crushing process does not limit the size of the final granular garbage, and it can be crushed as small as possible; the maximum centrifugal force will cut the granular garbage slightly larger than 6mm into 6mm granular garbage by the knife-like discharge hole 705 on the side wall of the crushing basket 701, so that it can pass the screening of the crushing layer 7 and enter the grinding disc layer 8; according to normal operation for 3-10 minutes, after the stirring and collision in the crushing basket 701 reaches a certain particle size requirement, it is discharged from the knife-like discharge hole 705 and flows to the feeding layer 6 on the upper part of the upper grinding disc 801. The size of the garbage particles is controlled by the 6mm diameter discharge hole, and the large granular garbage that does not meet the requirements cannot flow out of the crushing basket 701 until it fully meets the requirements before flowing to the lower level for processing;

[0086] (4) Grinding: Figure 6 to Figure 8-4As shown, the small particles of garbage less than 6 mm processed by the crushing layer 7 flow from the feed layer 6 and the feed hole 805 of the upper grinding disc 801 into the extrusion grinding area of ​​the upper grinding disc 801; when the lower grinding disc 802 rotates, the pulp garbage flowing out from the pulp discharge hole A 808 is cut and crushed for the last time; the grinding disc layer 8 and the crushing layer 7 operate asynchronously, and the upper grinding disc 801 is a fixed body. After being processed in the extrusion grinding area, it becomes smaller and gradually squeezed to the small gap cutting and grinding area for small gap cutting and grinding, and finally reaches the gapless cutting and grinding area. The reverse cutting grooves of the upper and lower grinding discs 802 cut and grind the garbage particles into pulp-like juice, and the cut pulp flows out of the pulp discharge hole B 905 is discharged to the garbage discharge layer 9; during operation, the grinding effect is not affected by the hardness of the particles, because the upper grinding disc 801 and the lower grinding disc 802 cannot move up and down, the harder the particles are, the greater the pressure of the fixed disc will be, and even the harder particles will be squeezed, ground, cut and crushed; the cutting and grinding speed of the upper and lower grinding discs 802 cannot be the same as the rotation speed of the crushing layer 7, and the rotation speed of the lower grinding disc 802 is only 900 rpm under the action of the reduction gear, and its maximum grinding speed is only 4.47 m / s;

[0087] (5) Discharging: Figure 9-1 , Figure 9-2 As shown, the slurry discharge solenoid valve 903 is opened, and the slurry fluid garbage flowing out from the slurry discharge hole A 808 of the lower grinding disc 802 is cut by the slurry discharge hole B 905 on the edge of the gear fixed disc 901, and then flows into the slurry discharge inclined disc 902 from the slurry discharge hole B 905, and flows through the hole of the cylinder 403 along the slurry discharge inclined disc 902. When the solenoid valve is opened, the slurry flows from the through hole on the solenoid valve, through the connecting pipe of the slurry discharge port 904, and is discharged into the sewer; the slurry discharge solenoid valve 903 can be adjusted to discharge garbage slurry without stopping the machine; the slurry discharge solenoid valve 903 can be automatically controlled according to the required amount, and the adjustment of the slurry discharge solenoid valve 903 can control the discharge amount, and at the same time adjust the discharge amount of small particle garbage from the knife-like discharge hole 705 on the side wall of the crushing basket 701, and the flow rate of small particle garbage flowing into the extrusion grinding area of ​​the upper grinding disc 801 from the feed hole 805 of the upper grinding disc 801.

[0088] For larger kitchen waste, you can directly open the upper cover 402 and put the waste into the crushing basket 701 with a diameter of 200 mm. Then cover the upper cover 402 and connect it to the water outlet pipe 1 of the pool 3 to start normal processing of the kitchen waste. For the very small amount of hard bone large particles that cannot be crushed for a long time, regularly open the maintenance cover 406 to manually remove them from the crushing basket 701 and treat them as wet garbage classification. The machine does not bear the burden of crushing unprocessed large hard bones.

[0089] When the water pool 3 is used as the feed storage device of the garbage disposer, since the feed hole 805 of the water pool 3 is very large, hard objects such as a spoon may be mixed into the crushing layer 7 of the garbage disposer, causing damage to the garbage disposer. After starting the machine, if an abnormal sound is heard, the machine should be stopped immediately, the maintenance cover 406 should be opened to take out the foreign matter, and then the maintenance cover 406 should be tightened and restarted; generally, foreign objects that can enter the garbage disposer will not cause damage to the processor, and abnormal sounds may not be heard. Therefore, after one week of use, the maintenance cover 406 should be opened to check whether there are any foreign objects stored in the processor; if the feeding is strictly controlled, it is not necessary to open the maintenance cover 406 for inspection.

Put the kitchen waste directly into the sink and turn on the tap above the sink to fill the garbage disposal with water. Dispose of the waste while draining the water or add vegetable washing water. The amount of water added should not exceed the height of the sink outlet. Vegetable and fruit waste, meat waste, and rotten food waste vary greatly in size and can all be placed directly in the sink. Kitchen waste should be initially processed to less than 35 mm and placed in the sink, and then automatically flow into the upper internal space of the crushing layer, i.e., the feed layer.

After being processed in the extrusion grinding area, it becomes smaller and gradually squeezed to the small gap cutting and grinding area for small gap cutting and grinding, and finally reaches the gapless cutting and grinding area. The reverse cutting grooves of the upper and lower grinding discs cut the garbage into small gaps. The garbage particles are cut and ground into slurry, and the cut slurry is discharged from the slurry discharge hole B to the garbage discharge layer; during operation, the grinding 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 greater the pressure of the fixed disc will be, and even the harder particles will be squeezed, ground, cut and crushed; the cutting and grinding speed of the upper and lower grinding discs cannot be the same as the rotation speed of the crushing layer.
