Description

Technical Field

[0001] The utility model relates to the technical field of food waste treatment, in particular to a secondary grinding structure of a food waste processor. Background Art

[0002] With the increasing popularity of food waste processors and the stricter requirements for garbage classification and reduction, the standards for food waste processors are getting higher and higher, and the grinding performance requirements for food waste processors themselves are also getting higher and higher. At present, the products that can provide food waste treatment for families in the market are mainly food waste processors. Existing food waste processors generally have the problem of being relatively difficult to treat long-fiber food waste.

[0003] A fine grinding structure for a food waste processor and a food waste processor were disclosed on July 22, 2022, with the publication number CN217017926U. The fine grinding structure for the food waste processor includes a fixed sieve plate, a grinding plate and a pressure wheel. The grinding plate is rotatably arranged above the fixed sieve plate. An upper scraping blade and a lower scraping blade that cooperate to crush food waste are arranged between the fixed sieve plate and the grinding plate. The pressure wheel is rotatably arranged below the fixed sieve plate, and blades for driving food residues and wastewater to be discharged are arranged on the pressure wheel. This application solves the technical problems of poor grinding effect and unsmooth wastewater discharge of the food waste processor.

[0004] However, there are still certain deficiencies in the use of the above-mentioned fine grinding structure of the food waste processor. During the grinding process, long-fiber waste in the food waste may be difficult to be quickly ground and crushed, which may lead to slow grinding efficiency, long grinding time, and may also lead to an increase in water volume, and the cost needs to be further reduced.

[0033] Embodiment:

[0034] Refer to Figures 1-6 , a secondary grinding structure of a food waste disposer, including:

[0035] Housing 6;

[0036] Grinding disc 4, rotatably connected in housing 6;

[0037] Tooth disc 1, fixedly connected below grinding disc 4;

[0038] The grinding ring 2 is fixedly connected in the housing 6;

[0039] The sieve plate 3 is fixedly connected in the housing 6, and the sieve plate 3 is located directly below the toothed disk 1.

[0040] A driving motor 501 is fixedly connected to the bottom of the housing 6, and a motor shaft 5 is fixedly connected to the driving end of the driving motor 501. The motor shaft 5 is fixedly connected to the grinding disk 4.

[0041] A flanging 102 is fixedly connected to the toothed disk 1, and multiple groups of cutting teeth 103 are arranged on the flanging 102. The multiple groups of cutting teeth 103 are evenly distributed on the flanging 102.

[0042] Refer to Figure 4 , bevel edges 104 are arranged on both sides of the flanging 102, and the two groups of bevel edges 104 are located on both sides of the cutting teeth 103.

[0043] A first grinding tooth 201 is fixedly connected to the bottom of the grinding ring 2, and a second grinding tooth 301 is fixedly connected to the sieve plate 3.

[0044] A weight-reducing hole 107 and a mounting hole 101 matching the motor shaft 5 are formed in the toothed disk 1.

[0045] Refer to Figure 3 , by means of the weight-reducing hole 107 formed in the toothed disk 1, the overall weight of the toothed disk 1 can be reduced, and thus the rotation and grinding of the toothed disk 1 are facilitated.

[0046] A first rivet hole 105 and a second rivet hole 106 are formed in the toothed disk 1.

[0047] Refer to Figure 2 , Figure 4 , when the toothed disk 1 is installed on the grinding disk 4, multiple groups of rivets can be respectively inserted into the first rivet hole 105 and the second rivet hole 106, and thus the toothed disk 1 is fixedly installed on the grinding disk 4.

[0048] A first cutting edge 108 is fixedly connected to the toothed disk 1.

[0049] A second cutting edge 303 is fixedly connected to the sieve plate 3.

[0050] Refer to Figure 2 , Figure 4 , Figure 6 , the first cutting edge 108 and the second cutting edge 303 are arranged in a staggered manner to ensure that when the toothed disk 1 rotates, the two groups of cutting edges will not collide and interfere with each other.

[0051] A positioning flange 302 is fixedly connected to the sieve plate 3, and the positioning flange 302 corresponds to the support leg 202.

[0052] Refer toFigure 5 , Figure 6 , the positioning hem 302 is located directly below the support leg 202, and the sieve tray 3 is folded over the support leg 202 through the positioning hem 302 and fixedly connected to the grinding ring 2.

[0053] Referring to Figures 1-6 , during use, the drive motor 501 drives the motor shaft 5 to rotate. The rotation of the motor shaft 5 will drive the grinding disc 4 and the gear disc 1 to rotate. At this time, the grinding hammers on the grinding disc 4 rotate, and the relative scraping movement between the grinding hammers and the grinding ring 2 will initially crush the food waste.

[0054] The food waste that has been initially crushed will fall onto the cutting teeth (103) through the gap between the grinding disc 4 and the grinding ring 2 under the action of water flow. Some fine food waste will fall onto the first grinding teeth 201 through the holes on the grinding ring 2 and finally fall into the gap between the cutting teeth 103 and the first grinding teeth 201 through the gaps between the first grinding teeth 201. At this time, the first cutting edge 108 makes a circular motion, and the relative movement between the cutting teeth 103 and the first grinding teeth 201 and the second grinding teeth 301 squeezes, scrapes, grinds, and tears the food waste.

[0055] Due to the symmetrical fan-shaped design of the grinding tooth disc 1, a part of the initially crushed food waste will fall onto the sieve tray 3 under the pushing and pulling action of water flow and the fan-shaped tooth disc 1, and is torn, ground, and scraped by the first cutting edge 108 and the second cutting edge 303. Finally, the fully crushed food waste is discharged from the grinding chamber under the extrusion of water flow and moving parts.

[0056] Due to the pulling action of the outward-turned grinding tooth disc 1, long-fiber food waste can be more easily pulled into the gap between the grinding disc 4 and the first grinding teeth 201, the first cutting teeth 103, and the second grinding teeth 301 for sufficient grinding, so as to achieve a more efficient crushing effect on the food waste.

[0057] Through this device, multi-stage grinding of food waste can be realized. After the food waste is initially crushed by the grinding hammers, it undergoes secondary grinding between the first grinding teeth 201, the cutting teeth 103, the second grinding teeth 301, and between the first cutting edge 108 and the second cutting edge 303. The grinding area and the number of grinding stages increase, and the fineness of the crushed particles is better. At the same time, by setting the outward-turned tooth disc 1, the long-fiber food waste can be pulled under the grinding disc 4 more quickly, thereby improving the grinding efficiency, reducing the grinding time, reducing the water volume, and reducing the waste of water resources.

[0058] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
