The kitchen waste disposer of the present embodiment is designed to be a closed structure in order to facilitate the installation of the tool set and maximize the utilization of space, and also facilitate the installation of water pipes. Among them, the role of the rough grinding mechanism 1 in the crushing mechanism is to rough process the kitchen waste, and the role of the fine grinding mechanism 2 is to reprocess the food. When we pour the kitchen waste through the primary grinding inlet at the top of the rough grinding protective cover 4 of the rough grinding mechanism 2, the kitchen waste first enters the rough grinding mechanism 1 for preliminary crushing, wherein the rough crushing blade 20 passes through the two crushing shafts 16 The connected crushing gear 21 completes the transmission between the two shafts. When the rough grinding motor rotates at high speed, it drives the crushing gear 21 to rotate, thereby driving the two crushing shafts 16 with the rough crushing blades 20 to rotate in the same meshing manner. When large pieces of bone or block objects fall into it, the bones will be broken. , a part of the small bones or block objects are thrown onto the arc-shaped friction plate 14 for re-crushing and grinding under the action of centrifugal force, and then fall again between the two crushing shafts 16 to be squeezed and crushed. The bones are bounced back to the arc-shaped friction plate 14 to be broken again, and fall between the two crushing shafts 16 again until they pass through the meshing gap, and finally the hard-to-break kitchen waste including vegetable leaves, eggshells, vegetable roots , large bones and other large objects are ground into small objects, and the design of the crushing shaft 16 also has a protective function. Protect.

The kitchen waste that has been broken into small pieces will be mixed with water and then enter the fine grinding mechanism 2 for further crushing, and the grinding will be carried out at a high speed in a two-layer container equipped with a perforated inner liner 11 and a leak-mesh outer liner 13. The perforated inner pot 11 is connected to the drive shaft 10 on the fine grinding motor 7, and the leak-mesh outer pot 13 is fixed. When the perforated liner 11 and the fine crushing blade 12 are rotated at high speed, due to the relatively small gap, the aqueous solution will not flow out immediately but will stagnate in the container for some time. The large particles are crushed into extremely small particles, and the centrifugal force swings the larger granular objects out during high-speed rotation. The perforated inner pot 11 is fixed to form secondary fines when the rotating leaky mesh outer bladder 13 is fixed, and the small particles are mixed with water through the small holes of the perforated inner bladder 11 and the leaky mesh outer bladder 13. It leaks out into the collector at the bottom, and during the grinding process of the blade and the side, a part of the particles will pass through the bottom of the leak-mesh outer bladder 13 for grinding, and finally leak out into the collector through the leak-mesh; The pipe 27 is received into the residue receiving bucket 24 on the slag water separator, so as to carry out the next processing.

When the collected slag aqueous solution flows into the slag receiving pipe 27 and then into the slag receiving bucket 24 along the pipeline, the slag water separation motor 29 drives the gear set in the gear box 28 to rotate and then drives the variable pitch shaft 30 to rotate. The rotation of the shaft 30 drives the residue and waste water in the residue receiving barrel, and the variable pitch screw shaft 30 brings the slag aqueous solution into the filter device 25 where the steel wire rod 31 with the movable ring and the fixed ring is located, and there is a variable pitch screw shaft inside. 30 The outside is equipped with a steel wire rod 31 with a movable ring and a fixed ring, which protects the internal variable pitch screw shaft 30 and simultaneously separates the slag and water. The rotation of the shaft 30 and the subsequent rotation play a squeezing effect, the oil-water solution after the slag removal is continuously squeezed, and the water flows out through a tiny gap between the movable rings on the steel wire rod 31 of the filter device 25, and passes through the baffle 32. And the gap at the bottom of the filter device 25 for storing and separating the slag and water enters the next oil-water separation mechanism, and the slag is continuously squeezed and kept in the slag-water separator. A slip screen will be installed to separate a small part of the slag that was accidentally squeezed out during separation, and the extruded kitchen waste residue will be discharged downward from the variable pitch screw shaft 30 with the rotation of the internal variable pitch screw shaft 30 It falls into the drying and fermentation mechanism to complete the separation of the slag and water. The slag-water separator can maintain continuous and stable extrusion separation during operation, and the slag-water separator has a low failure rate and can be in working condition for a long time. Its high-efficiency slag removal and dewatering function is far beyond the average level, and its extrusion separation performance is far superior to the same specifications of the press and centrifuge on the market, and it is cost-effective. Its kitchen waste water yield is as high as 85%, and the dryness of the material after dehydration is as high as about 20%, showing an effect that is difficult to achieve by ordinary presses or dehydrators.

When the slag after the slag-water separation passes through the slag inlet pipe 39 connected under the variable-pitch rotary shaft 30 on the slag-water separator, it enters the residue drying and fermenting mechanism, and then uses the electric heating resistance wire to heat the upper heating pipe of the residue drying and fermenting mechanism. On the inner wall of the heat pipe on the stirring barrel 38, the residue in the stirring barrel 38 of the heating pipe is dried and fermented. The rotating shaft 42 slowly stirs the residue so that the residue is heated evenly, and finally achieves a purpose of drying. So that the slag can be heated evenly and finally achieve the effect of sterilization. When the slag in the stirring barrel 38 of the heating pipe is dried, it will be transferred to the lower heat-sealing packaging mechanism along with the continuous stirring of the slag drying and fermentation rotating shaft 42 .

The oil-water solution entering the oil-water separation mechanism will undergo two precipitation and separation of the oil and water in the oil-water solution to obtain the reuse of the water cycle. The oil and water flowing out of the gap between the rings flows into the baffle 32 and the gap at the bottom of the filter device 25 for storing and separating the slag and water, and then enters the oil-water collection tank 33 through the conduit. The upper oil collection pipe 36 flows into the oil collection tank 37, and the water flows into the water collection tank 35 through the lower water collection pipe 34. This is the first precipitation and filtration. When the oil is stored to a certain extent, the oil with high density will float up due to the density, while the oil with low density and a part of the water will also be below. When it needs to be collected, it is only necessary to open the pipe opening on the upper part of the oil collection tank. . The water in the water collection tank 35 will be collected through the pipeline, so as to obtain the secondary utilization of the water.

When the dried slag dropped from the drying fermentation mechanism falls into the wrapping paper on the heat-sealing packaging device conveyed by the flat belt 45 as organic fertilizer through the transmission of the conveyor belt 44, the two rollers 48 are used for packaging, and the heat The sealing and packaging device first heat-seals the packaging paper into a barrel-shaped closed space, and then transmits a part of the distance through the flat belt to achieve intermittent cutting and packaging, thereby cutting the packaging paper; finally, the bagged organic fertilizer is formed. The principle of heat sealing is to use The principle of resistance heating is realized. While rotating, it not only heat-seals the wrapping paper, but also pushes the wrapping paper backwards, and finally achieves the purpose of packaging.

The kitchen waste disposer of this embodiment is automated, that is, the poured kitchen waste can be processed by pressing a switch, and no other operations are required, which is convenient and labor-saving, and provides convenient services for users. In addition, the large and difficult-to-treat vegetable roots and bones can be treated; in the slag water treatment in the slag-water separation part, the slag and water can be treated twice, and 85% of the water in the slag aqueous solution can be recycled; therefore, this implementation For example, it reduces the disposal of garbage, beautifies the sanitation of the home environment, and helps users to cook more conveniently; secondly, the product is small in size, which can be applied to most household users; moreover, the product function makes the kitchen waste treatment more extensive and more efficient. The most important thing is to turn kitchen waste into organic fertilizer after grinding, slag-water separation, oil-water separation, drying fermentation, packaging, etc., and turn our kitchen waste into treasure, not only It can play a role in environmental protection and resource recycling in the family, while reducing garbage disposal, it cleans the environment of the family, reduces the amount of garbage disposal, and reduces the burden on each household, especially for the users of the community.
