Description

Technical Field

[0001] The present invention relates to the technical field of household garbage processors, and specifically to a solid-liquid separation structure of a garbage processor. Background Art

[0002] As a kitchen appliance, garbage processors are gradually becoming popular among household users. Food waste such as vegetable stalks, bones, and leftovers is put into the input port of the garbage processor. The garbage processor cuts and grinds the garbage until it is pulverized through the cooperation of a cutter head driven by a motor and a fixed grinding ring, and then discharges it into the sewer through the garbage outlet.

[0003] Common garbage processors cannot achieve solid-liquid separation of garbage. After the garbage is pulverized, the water in the garbage will be discharged from the garbage outlet together with the solid garbage. The processed garbage is usually relatively viscous and easily adheres to the inner wall of the sewer. In the long term, it is easy to cause sewer blockage; in addition, the processed garbage is only directly discharged into the sewer and cannot be recycled, which is not conducive to environmental protection and resource recovery. Summary of the Invention

[0004] The purpose of the present invention is to provide a solid-liquid separation structure of a garbage processor, which can separate the solid and liquid in the processed garbage and recycle the solid garbage therein.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A solid-liquid separation structure of a garbage processor, including a bottom shell, a cutter head, and a grinding ring. The cutter head is accommodated in the bottom shell and driven by a motor to rotate. The grinding ring surrounds the cutter head, and the grinding ring is provided with filter holes for discharging the garbage processed by the cutter head. This solid-liquid separation structure of the garbage processor further includes a water drainage ring, which surrounds the grinding ring and rotates coaxially with the cutter head; the water drainage ring forms a material receiving part, the material receiving part extends upward to a height higher than the filter holes, the top of the material receiving part forms an upper opening, and the material receiving part is provided with a number of drainage holes with smaller apertures than the filter holes; the bottom shell forms a lower step part and an upper step part, the lower step part is connected with a liquid flow channel, and the upper step part is connected with a solid channel; the material receiving part starts to extend from inside the lower step part until the upper opening communicates with the upper step part.

[0006] In the above technical solution, a retaining wall is provided at the inner edge of the upper step part, and the upper opening of the water drainage ring is bent to form a bent edge, and the bent edge extends in the horizontal direction to a position exceeding the retaining wall.

[0007] In the above technical solution, the front end of the bent edge extends obliquely downward.

[0008] In the above technical solution, a scraping blade extending to the upper step portion is provided at the bending edge for scraping garbage.

[0009] In the above technical solution, the material receiving portion extends obliquely upward.

[0010] In the above technical solution, the included angle between the material receiving portion and the cutter head is 110° - 130°.

[0011] In the above technical solution, the included angle between the material receiving portion and the cutter head is 120°.

[0012] In the above technical solution, a movable cutter block is provided on the cutter head, and a fixed cutter block that cooperates with the movable cutter block extends inward from the grinding ring.

[0013] In the above technical solution, grinding teeth are provided on the movable cutter block.

[0014] In the above technical solution, a secondary cutter is provided below the cutter head.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The solid-liquid separation structure of this garbage processor realizes the solid-liquid separation function of garbage through the cooperation between the water drainage ring coaxial with the cutter head and the lower step portion and the upper step portion of the bottom shell. The water and solid garbage with smaller particle sizes in the processed garbage enter the lower step portion of the bottom shell through the water drainage holes on the water drainage ring, and the solid garbage with larger particle sizes enters the upper step portion of the bottom shell under the action of centrifugal force. The water and solid garbage with smaller particle sizes in the garbage are discharged into the sewer, which is not likely to cause sewer blockage. The solid garbage with larger particle sizes can be recycled and reused, which is beneficial to environmental protection and resource recovery. Description of the Drawings

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1 , a solid-liquid separation structure of a garbage processor, including a bottom shell 4, a cutter head 1 and a grinding ring 2.

[0027] The bottom shell 4 is a metal shell, which can be joined with an upper shell (not shown) to form the inner shell of the garbage processor.

[0028] The cutter head 1 is a metal disc body, and its material is preferably stainless steel or aluminum alloy; the cutter head 1 is provided with movable cutter blocks 11, the material of the movable cutter blocks 11 is the same as that of the cutter head 1, and the movable cutter blocks 11 are pivotally connected to the disc surface of the cutter head 1 by screws, so that the movable cutter blocks 11 can revolve with the cutter head 1 and can rotate around their own screws; 2-4 movable cutter blocks 11 can be provided on the cutter head 1. In this embodiment, two movable cutter blocks 11 are provided.

[0029] The grinding ring 2 is a metal workpiece, and its material is the same as that of the cutter head 1; the grinding ring 2 is generally cylindrical, and the inner diameter of the grinding ring 2 is larger than the outer diameter of the cutter head 1.

[0030] Please refer to Figure 2 , Figure 6 and Figure 7, a shaft hole for the motor shaft to pass through is provided in the middle of the bottom plate of the bottom shell 4. The motor shaft 5 of the main motor of the garbage processor passes through the shaft hole and is supported in the shaft hole by a sealed bearing 6; after the motor shaft 5 passes through the shaft hole, a connecting frame 12 is sleeved on the motor shaft 5, and the connecting frame 12 is fixed to the motor shaft 5 by a nut; the cutter disc 1 is horizontally arranged, the cutter disc 1 is accommodated in the bottom shell 4, and the bottom surface of the cutter disc 1 is fixedly connected to the connecting frame 12 by screws, so that the motor can drive the cutter disc 1 to rotate. In this embodiment, after the screw of the movable cutter block 11 vertically passes through the movable cutter block 11 and the cutter disc 1, it is screwed into the threaded hole on the connecting frame 12, making the structure of the cutter disc 1 more compact and the assembly process simpler. A circular hole is also provided in the center of the cutter disc 1 for the top of the motor shaft 5 to pass through the circular hole during assembly, so as to prevent the top of the motor shaft 5 from pressing against the cutter disc 1 and affecting the installation of the cutter disc 1 and the connecting frame 12; a cover 14 for preventing water and garbage from entering the internal space of the connecting frame 12 is provided on the circular hole of the cutter disc 1. The cover 14 is made of rubber or silica gel, and the cover 14 is in interference fit with the circular hole of the cutter disc 1.

[0031] Please refer to Figures 1 - 3 , the grinding ring 2 is supported by the upper shell of the garbage processor and is fixed to the upper shell by means of screws or snaps, for example; the grinding ring 2 surrounds the cutter disc 1, and the grinding ring 2 extends inwards to form a fixed cutter block 22 that cooperates with the movable cutter block 11, that is, from a top view direction, the outer edge of the fixed cutter block 22 extends beyond the outer edge of the movable cutter block 11, so that the fixed cutter block 22 can cooperate with the rotating movable cutter block 11 to grind the garbage; in this embodiment, the fixed cutter block 22 is square and conical, and the square and conical fixed cutter blocks 22 are arranged circumferentially and alternately on the inner side of the grinding ring 2; filter holes 21 for discharging the garbage after being ground by the cutter disc 1 are provided on the grinding ring 2, the aperture of each filter hole 21 is the same, the diameter of the filter hole 21 is 3 - 5 mm, and all the filter holes 21 are evenly arranged on the grinding ring 2; when the movable cutter block 11 of the cutter disc 1 cooperates with the fixed cutter block 22 of the grinding ring 2 to cut and grind the garbage until the garbage particles are smaller than the filter holes 21, the garbage can pass through the filter holes 21.

[0032] The above structure constitutes the basic structure of the garbage processor. To achieve the function of solid-liquid separation, the solid-liquid separation structure of this kind of garbage processor further includes a water drainage ring 3.

[0033] Please refer to Figure 1 , Figure 2 , Figures 5 - 7, the water draining ring 3 is a metal workpiece, and its material is the same as that of the cutter head 1; the inner ring of the water draining ring 3 is an installation edge 36 which is horizontally arranged for connecting with the outer peripheral edge of the cutter head 1. The installation edge 36 is fixedly connected with the bottom surface of the cutter head 1 by means of screws or welding. The installation edge 36 extends horizontally continuously until it exceeds the grinding ring 2; the water draining ring 3 forms a material receiving part 31 outside the installation edge 36. The material receiving part 31 extends upward to a height higher than that of the filtering holes 21. Specifically, the material receiving part 31 extends upward to a height higher than that of any one of the filtering holes 21; the top of the material receiving part 31 forms an upper opening 33. The material receiving part 31 is provided with a plurality of draining holes 32 with apertures smaller than those of the filtering holes 21. All the draining holes 32 are evenly distributed on the material receiving part 31; the diameter of the draining holes 32 is 0.8 - 1.2 mm, preferably 1 mm.

[0034] The bottom shell 4 forms a lower step part 41 and an upper step part 42. That is, when viewed from the sectional view in the front view direction, the bottom shell 4 is in an inverted "convex" shape; the lower step part 41 is connected with a liquid flow channel 43. The liquid flow channel 43 is integrally formed with the lower step part 41, or an interface is opened in the lower step part 41, and a flexible pipe is connected into the interface as the liquid flow channel 43; the upper step part 42 is connected with a solid channel 44. The solid channel 44 is integrally formed with the upper step part 42, or an interface is opened in the upper step part 42, and a flexible pipe is connected into the interface as the solid channel 44; the material receiving part 31 of the water draining ring 3 extends upward from inside the lower step part 41 until the upper opening 33 of the water draining ring 3 communicates with the upper step part 42.

[0035] During use, the liquid flow channel 43 communicates with the sewer, and the solid channel 44 communicates with the user's recycling bin; garbage such as vegetable stalks, bones and leftovers is put into the garbage disposer from the upper shell inlet and is picked up by the cutter head 1. After starting the motor, the motor shaft 5 rotates and drives the cutter head 1 to rotate. The movable cutter blocks 11 of the cutter head 1 cooperate with the fixed cutter blocks 22 of the grinding ring 2 to cut and grind the garbage until the garbage particles are smaller than the filtering holes 21. Then the garbage passes through the filtering holes 21 and is then picked up by the material receiving part 31 of the water draining ring 3. The water contained in the garbage is thrown out after passing through the draining holes 32 of the water draining ring 3 under the action of centrifugal force. At the same time, the solid garbage with a particle diameter smaller than the aperture of the draining holes 32 will also pass through the draining holes 32 and enter the lower step part 41. This part of the solid garbage and water reach the lower step part 41 of the bottom shell 4 and are led out through the liquid flow channel 43 and flow into the sewer. Since the aperture of the draining holes 32 is smaller than that of the filtering holes 21, the solid garbage with a particle diameter larger than the aperture of the draining holes 32 cannot pass through the draining holes 32 and is thus dehydrated. Subsequently, under the action of centrifugal force, this part of the solid garbage is thrown to the top of the water draining ring 3 and enters the upper step part 42 of the bottom shell 4 through the upper opening 33 of the water draining ring 3. Finally, it is led out through the solid channel 44 and enters the user's recycling bin. After the user recycles the solid garbage particles, they can be used as fertilizers.

[0036] Please refer to Figures 6 - 8 , further, a retaining wall 45 is provided at the inner edge of the upper step portion 42. The retaining wall 45 is integrally formed with the inner edge of the upper step portion 42, and the retaining wall 45 continuously extends along the inner edge of the upper step portion 42 to form a ring; the upper opening 33 of the water drainage ring 3 is bent to form a bent edge 34, and the bent edge 34 extends horizontally to a position beyond the retaining wall 45; the front end of the bent edge 34 is further bent and extended obliquely downward, so that the bent edge 34 surrounds the retaining wall 45. The solid garbage particles thrown out from the water drainage ring 3 slide along the bent edge 34 into the upper step portion 42 and are blocked by the retaining wall 45, preventing the solid garbage particles from mistakenly entering the lower step portion 41.

[0037] Please refer to Figure 7 , further, the material receiving portion 31 of the water drainage ring 3 extends obliquely upward from the outer edge of the mounting edge 36, and the included angle between the material receiving portion 31 and the cutter head 1 is 110° - 130°. In some possible embodiments, the included angle between the material receiving portion 31 and the cutter head 1 can be set to 110°, 115°, 125°, and 130°, preferably 120°. If the included angle between the material receiving portion 31 and the cutter head 1 is too small, making the slope of the material receiving portion 31 too steep, the solid garbage particles are likely to stay in the material receiving portion 31, prolonging the garbage treatment time; if the included angle between the material receiving portion 31 and the cutter head 1 is too large, making the slope of the material receiving portion 31 too gentle, the solid garbage particles are likely to be quickly thrown out from the material receiving portion 31, resulting in insufficient dehydration time; selecting 110° - 130° and preferably 120° as the included angle between the material receiving portion 31 and the cutter head 1 enables the garbage particles to be fully dehydrated without staying in the material receiving portion 31 for too long a time.

[0038] Further, scraping blades 35 extending to the upper step portion 42 are provided at the bent edge 34. In this embodiment, the scraping blades 35 are rectangular parallelepipeds, and four scraping blades 35 are uniformly arranged at the bent edge 34 of the water drainage ring 3, and all the scraping blades 35 are welded or screwed to the water drainage ring 3. By providing the scraping blades 35 extending to the upper step portion 42 at the bent edge 34, when the water drainage ring 3 rotates with the cutter head 1, the scraping blades 35 also move circumferentially with the water drainage ring 3, thereby scraping the solid garbage at the upper step portion 42 until the solid garbage is scraped to the entrance of the solid channel 44 and enters the solid channel 44, preventing the solid garbage from staying at the upper step portion 42.

[0039] Please refer to Figure 4 , further, grinding teeth 111 are provided on the movable cutter block 11. In this embodiment, the grinding teeth 111 are raised portions distributed on the outer edge of the movable cutter block 11, and the grinding teeth 111 are integrally formed with the movable cutter block 11; through the grinding teeth 111, the garbage can be further cut, shortening the grinding treatment time of the garbage.

[0040] Further, a secondary knife 13 is provided below the cutter head 1. The secondary knife 13 is sleeved on the motor shaft 5. In this embodiment, the material of the secondary knife 13 is the same as that of the cutter head 1, and the secondary knife 13 extends in the horizontal direction. After the motor shaft 5 passes through the shaft hole of the bottom shell 4, the secondary knife 13 is sleeved on the motor shaft 5, and then the connecting frame 12 is sleeved on the motor shaft 5, so that the connecting frame 12 is located above the secondary knife 13. The secondary knife 13 and the connecting frame 12 are fixed on the motor shaft 5 by nuts. The provision of the secondary knife 13 can further crush the solid waste that has strayed into the lower step portion 41, avoiding the blockage of the liquid flow channel 43.

[0041] In the solid-liquid separation structure of this garbage processor, through the cooperation between the water drainage ring 3 that rotates coaxially with the cutter head 1 and the lower step portion 41 and the upper step portion 42 of the bottom shell 4, the water and the solid waste with smaller particle sizes in the processed garbage enter the lower step portion 41 of the bottom shell 4 through the water drainage holes 32 on the water drainage ring 3, and the solid waste with larger particle sizes enters the upper step portion 42 of the bottom shell 4 under the action of centrifugal force, realizing the solid-liquid separation function of the garbage; the water and the solid waste with smaller particle sizes in the garbage are discharged into the sewer, which is not likely to cause the blockage of the sewer, and the solid waste with larger particle sizes can be recycled and reused, which is beneficial to environmental protection and resource recovery.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
