However, although existing technology can perform solid-liquid filtration of waste, when filtering large amounts of waste, the repulsive force generated by the rotation of the squeezing rollers inside the device can cause waste to accumulate and become blocked. Therefore, the working efficiency of existing technology is not stable when filtering large amounts of waste.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a solid-liquid filtration device for kitchen waste includes: a housing 20, which is a rectangular box with a hollow interior. Rectangular grooves are provided on the upper half of the front and rear walls of the housing 20. A rectangular opening is provided on the top of the housing 20. A transparent plate is installed in the rectangular opening on the top of the housing 20. A main motor 21 is fixedly connected to one side wall of the housing 20. Drain pipes 22 are symmetrically fixedly connected to the bottom of the other side of the housing 20. The drain pipes 22 are hollow circular tubes. A valve is installed at each drain pipe 22.

[0034] The brackets 23 are symmetrically fixedly connected to the top of the cavity of the housing 20. Each set of symmetrical brackets 23 is rotatably connected to an active roller 24. The active roller 24 is cylindrical. The main motor 21 can drive the active roller 24 to rotate. Each active roller 24 has a limiting disc 25 symmetrically fixedly connected to its arc surface. The limiting disc 25 is disc shaped. A transmission belt 26 is connected to the wall of the symmetrical active roller 24. The transmission belt 26 is located between the symmetrical limiting discs 25. The wall of the transmission belt 26 is evenly provided with a large number of circular meshes. The main motor 21 is electrically connected to the corresponding power supply. The connection method between the transmission belt 26 and the active roller 24 is similar to the connection method of belt and belt gear. This is existing technology and will not be described in detail here.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the separation structure is set inside the cavity of the housing 20 to separate solid and liquid waste. The separation structure includes: an upper pressure roller 31, an anti-slip rod 32, a lower pressure roller 33, and an anti-slip groove 37. The upper pressure roller 31 is set inside the cavity of the housing 20, the anti-slip rod 32 is fixedly connected to the wall of the upper pressure roller 31, the lower pressure roller 33 is also set inside the cavity of the housing 20, and the anti-slip groove 37 is opened on the outer wall of the transmission belt 26. The upper pressure roller 31 can crush the waste.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the upper pressure roller 31 and the lower pressure roller 33 are cylindrical with the same dimensions. The anti-slip rod 32 is a rod with an isosceles triangular cross section. Multiple identical anti-slip rods 32 are uniformly fixedly connected to the arc surface of the upper pressure roller 31. The lower pressure roller 33 is located below the upper pressure roller 31 and is located on the inner wall of the transmission belt 26. The anti-slip groove 37 is a rectangular groove. Multiple identical anti-slip grooves 37 are uniformly opened on the outer wall of the transmission belt 26. The separation structure also includes a support plate 30, a limiting rod 34, a scraper rod 35, and a collecting groove 36. The support plate 30 is symmetrically fixedly connected to the top of the cavity of the housing 20. The support plate 30 is a rectangular plate. The two ends of the upper pressure roller 31 are rotatably connected to the symmetrical support plate 36. Between the plates 30, the two ends of the lower pressure roller 33 are also rotatably connected between the symmetrical support plates 30. The limiting rod 34 is fixedly connected to the front wall of each support plate 30. The scraper rod 35 is fixedly connected to the rear wall of the symmetrical support plate 30. The collecting groove 36 is opened on the outer wall of the transmission belt 26. The limiting rod 34 is a rod with a parallelogram cross section. The bottom of the limiting rod 34 can contact the top of the transmission belt 26. The scraper rod 35 is a rod with a triangular cross section. The scraper rod 35 is close to the rear of the upper pressure roller 31. The collecting groove 36 is a groove that is recessed towards the inner wall of the transmission belt 26. The anti-slip groove 37 is located at the collecting groove 36. The dimensions of the two sides of the collecting groove 36 are consistent with the spacing of the symmetrical limiting rod 34.

[0037] In practical use, first turn on the power and place the waste to be filtered from the opening on the front wall of the casing 20 into the collection trough 36 at the top of the transmission belt 26. When the main motor 21 is powered on, it drives the active roller 24 to rotate. The rotating active roller 24 drives the transmission belt 26 and, in conjunction with another active roller 24, drives it backward. When the waste is placed on top of the transmission belt 26, it will be located between the symmetrical limit rods 34 and move downwards towards the upper pressure roller 31. One of the support plates 30 has a motor installed on its side wall to drive the upper pressure roller 31 and the lower pressure roller 33 to rotate. The motor can be turned on when the main motor 21 is powered on. When the waste moves with the transmission belt 26 to below the upper pressure roller 31, the rotating upper pressure roller 31 can drive the anti-slip rod 32 to crush the top of the waste. The anti-slip rod 32 can be inserted into the outer wall of the waste when in contact with it. The scraper 35 can scrape the waste stuck on the anti-slip rod 32 onto the top of the transmission belt 26. When the waste is crushed by the upper pressure roller 31, it will bring downward pressure to the waste and the transmission belt 26. When the waste and the transmission belt 26 are pressed downward, they will be pushed upward by the rotating lower pressure roller 33, thereby achieving the filtration of liquid in the waste. The filtered liquid will pass through the mesh at the top of the transmission belt 26 and accumulate at the bottom of the chamber 20. Then, when the waste passes between the upper pressure roller 31 and the lower pressure roller 33, it will continue to move backward with the transmission of the transmission belt 26. Then the waste will move to the point where it separates from the top of the transmission belt 26 and falls onto the top of the guide plate 41. The liquid dripping from the waste on the top of the guide plate 41 will leak down the circular groove at the top of the guide plate 41 to the bottom of the chamber 20. Then the waste will move out through the opening at the rear of the chamber 20 along the inclined surface at the top of the guide plate 41, thus completing the filtration. When it is necessary to drain the liquid in the chamber 20, the valve of the drain pipe 22 can be opened to drain the liquid at the bottom of the chamber 20 through the drain pipe 22.

[0038] In summary, by setting up a separation structure, the waste to be filtered can be gradually pressed and filtered through the transmission belt 26, thereby filtering all the waste entering the chamber 20. Furthermore, by setting up anti-slip rods 32 and anti-slip grooves 37, the problem of waste sliding during the pressing and filtering process can be effectively prevented. Therefore, this solution has a more stable working efficiency compared to the existing technology.

[0039] like Figure 6As shown, a guide structure is provided at the symmetrical support 23 at the rear. The guide structure includes a rear scraper 40, a guide plate 41, and a drain rod 42. The rear scraper 40 is fixedly connected to the front wall of the guide plate 41, and the guide plate 41 is fixedly connected to the rear wall of the symmetrical support 23 at the rear. The drain rod 42 is fixedly connected to the top of the guide plate 41. The rear scraper 40 is a rectangular plate, and the front end of the rear scraper 40 can be aligned with the rear end of the transmission belt 26. The guide plate 41 is obliquely placed on the wall of the support 23. The guide plate 41 is a rectangular plate, and the drain rod 42 is a rod with an isosceles triangular cross section. Multiple identical drain rods 42 are evenly arranged on the top of the guide plate 41. Multiple circular grooves are opened on the top of the guide plate 41 between each adjacent drain rod 42. The bottom of the rear end of the guide plate 41 can rest on the opening of the rear wall of the chassis 20.

[0040] In actual use, the waste will move to separate from the top of the conveyor belt 26 and fall onto the top of the guide plate 41. The liquid dripping from the waste on the top of the guide plate 41 will leak down the circular groove on the top of the guide plate 41 to the bottom of the chamber 20. Then the waste will be moved out from the opening at the rear of the chamber 20 along the inclined surface on the top of the guide plate 41, thus completing the filtration.

[0041] In summary, by setting up a guiding structure, the residual liquid remaining in the waste after being filtered by the separation structure can be guided and recycled, thereby preventing the residual liquid from dripping onto the ground.

[0042] like Figure 5 As shown, a cleaning structure is provided at the bottom of the symmetrical front bracket 23. The cleaning structure includes a sub-plate 43 and a cleaning roller 44. The sub-plate 43 is fixedly connected to the bottom of each front bracket 23. The cleaning roller 44 is rotatably connected between the symmetrical sub-plates 43. The cleaning roller 44 is cylindrical. A brush is installed on the arc surface of the cleaning roller 44. The brush on the wall of the cleaning roller 44 can contact the outer wall of the transmission belt 26.

[0043] In practical use, when the drive roller 24 rotates, a belt and pulley are installed on one side of the drive roller 24, and a pulley is also installed on one side of the cleaning roller 44. The limit disc 25 can drive the cleaning roller 44 to rotate synchronously through the belt. The rotating cleaning roller 44 can drive the brush on its wall to clean the outer wall of the transmission belt 26 that passes through.

[0044] In summary, by setting up a cleaning structure, not only can the transmission belt 26 be cleaned, but the problem of the mesh on the wall of the transmission belt 26 being clogged and reducing the filtration efficiency can also be prevented.

[0045] Working principle: When the waste is placed on top of the conveyor belt 26, it will be positioned between the symmetrical limit bars 34 and move downwards towards the upper pressure roller 31. A motor for driving the upper pressure roller 31 and lower pressure roller 33 is installed on the side wall of one of the support plates 30. The motor can be turned on when the main motor 21 is powered on. When the waste moves with the conveyor belt 26 to below the upper pressure roller 31, the rotating upper pressure roller 31 can drive the anti-slip bar 32 to crush the top of the waste. The anti-slip bar 32 can insert into the outer wall of the waste when in contact with it, scraping... The rod 35 can scrape the garbage stuck on the anti-slip rod 32 onto the top of the transmission belt 26. When the garbage is crushed by the upper pressure roller 31, it will bring downward pressure to the garbage and the transmission belt 26. When the garbage and the transmission belt 26 are pressed downward, they will be pushed upward by the rotating lower pressure roller 33, thereby achieving the pressure filtration of liquid in the garbage. The filtered liquid will concentrate and pass through the mesh at the top of the transmission belt 26 and accumulate at the bottom of the chamber 20. Then, when the garbage passes between the upper pressure roller 31 and the lower pressure roller 33, it will continue to move backward with the transmission of the transmission belt 26.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
