Description

Technical Field

[0001] This utility model relates to a dewatering device, and more particularly to a dewatering device for kitchen waste residue, belonging to the field of kitchen waste treatment technology. Background Technology

[0002] Food waste, also known as kitchen waste or organic waste, mainly comes from food processing and consumption in households, restaurants, canteens, and other catering establishments. This type of waste is characterized by high moisture content, high organic matter content, and easy decomposition. If not handled properly, it can easily cause environmental pollution and sanitation problems.

[0003] Food waste residue typically contains a large amount of moisture. During the stacking or landfilling process, this high-moisture residue generates a large amount of leachate, which contains high concentrations of organic matter, grease, salt, and pathogenic microorganisms. If this leachate enters the soil or water bodies directly without treatment, it will cause serious environmental pollution. Furthermore, the large weight and volume of the high-moisture residue increase the difficulty and cost of transportation. Therefore, a food waste residue dewatering device is proposed.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown, this utility model embodiment provides a dewatering device for kitchen waste residue, including a main component 10. The main component 10 includes a shell 11, a first hydraulic cylinder 15, a first pressure plate 16, a second hydraulic cylinder 17, a second pressure plate 18, and a filter plate 19. The first hydraulic cylinder 15 is installed on one side of the shell 11, and the first pressure plate 16 is fixedly connected to one end of the piston rod of the first hydraulic cylinder 15. The second hydraulic cylinder 17 is installed on the side of the shell 11 away from the first hydraulic cylinder 15, and the second pressure plate 18 is fixedly connected to one end of the piston rod of the second hydraulic cylinder 17. The filter plate 19 is fixedly connected to the inner wall of the shell 11. The surface of the filter plate 19 is uniformly provided with through holes. The first hydraulic cylinder 15 and the second hydraulic cylinder 17 drive the pressure plate to move. The two pressure plates squeeze the kitchen waste residue to dewater the residue and reduce the moisture content. The squeezed water passes through the filter plate 19 and falls onto the baffle 25, and falls into the bottom of the shell 11 from the gaps on both sides of the baffle 25.

[0027] The main body component 10 is equipped with a conveying component 20, which includes a filter tube 24, a baffle 25, a second motor 26, a drive shaft 27, and a spiral blade 28. The filter tube 24 is fixedly connected to the inner wall of the housing 11, and one end of the filter tube 24 extends through the housing 11 to the outside. The baffle 25 is fixedly connected to the inner wall of the housing 11 and is positioned above the filter tube 24. The second motor 26 is installed on one side of the housing 11, and the output shaft of the second motor 26 is fixedly connected to one end of the drive shaft 27. The spiral blade 28 is fixedly connected to the outer wall of the drive shaft 27. The outer surface of the drive shaft 27 is conical, and its two ends have different diameters. During the tailings conveying process, as the diameter of the drive shaft 27 gradually increases, the tailings are squeezed and undergo secondary dewatering. The surface of the filter tube 24 is uniformly provided with through holes. There are gaps between the two sides of the baffle 25 and the housing 11 to allow the waste liquid to flow downwards. The baffle 25 is used to prevent the waste liquid from dripping onto the filter tube 24.

[0028] In this embodiment, specifically: a feed inlet 12 is provided on the top of the shell 11, through which kitchen waste residue enters the interior of the shell 11.

[0029] In this embodiment, specifically: a cover plate 13 is hinged to the top of the feed inlet 12.

[0030] In this embodiment, specifically: the cover plate 13 and the feed port 12 are fixedly connected by a latch 14. After the latch 14 fixes the cover plate 13, it can prevent the cover plate 13 from moving during the extrusion process.

[0031] In this embodiment, specifically: support legs 110 are symmetrically and fixedly connected to the bottom of the housing 11, and the support legs 110 play a role in stabilizing support.

[0032] In this embodiment, specifically: the bottom of the housing 11 is connected to a drain pipe 111, and a valve 112 is installed on the drain pipe 111. The waste liquid generated by dehydration is discharged through the drain pipe 111 and collected and treated in a unified manner. The valve 112 is used to control the opening and closing of the drain pipe 111.

[0033] In this embodiment, specifically: a first motor 21 is symmetrically installed on one side of the housing 11, and the first motor 21 drives the crushing roller 22 to rotate.

[0034] In this embodiment, specifically: a feed hopper 23 is fixedly connected to the inner wall of the housing 11, the feed hopper 23 is connected to the filter pipe 24, and two crushing rollers 22 are symmetrically rotatably connected to the inner wall of the feed hopper 23. The crushing rollers 22 are fixedly connected to the output shaft of the first motor 21, and the surface of the crushing rollers 22 is provided with crushing teeth for crushing tailings. The crushing of the compressed tailings is completed by the cooperation of the two crushing rollers 22.

[0035] In operation, the following steps are taken: Kitchen waste residue enters the housing 11 through the inlet 12 and falls onto the filter plate 19. After the residue is conveyed, the cover plate 13 is locked by the latch 14. The first hydraulic cylinder 15 and the second hydraulic cylinder 17 drive the pressure plates to move, squeezing the kitchen waste residue to dehydrate it and reduce its moisture content. The squeezed water passes through the filter plate 19 and falls onto the baffle 25, then falls into the bottom of the housing 11 through the gaps on both sides of the baffle 25. The remaining residue moves through the two pressure plates and is conveyed to the top of the feed hopper 23. A motor 21 drives the crushing roller 22 to rotate, redispersing the compressed tailings so that they can enter the filter tube 24. After entering the filter tube 24, the tailings are driven by a second motor 26 to rotate the drive shaft 27, which in turn drives the spiral blade 28 to rotate, thus conveying the initially dewatered tailings. During the conveying process, as the diameter of the drive shaft 27 gradually increases, the tailings are squeezed to complete the secondary dewatering, ensuring the dewatering effect and preventing the tailings from being too wet and causing environmental pollution. At the same time, it reduces the transportation cost and difficulty of the tailings. The waste liquid generated during dewatering is discharged through the drain pipe 111 and collected for unified treatment.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
