Technical Field

[0001] This utility model relates to the field of solid-liquid separation and treatment technology for kitchen waste, and in particular to a solid-liquid separation device for kitchen waste treatment. Background Technology

[0002] Kitchen waste is characterized by high moisture content, high organic matter moisture content, high grease moisture content, and high salt content. These characteristics make it prone to spoilage and rotting, producing leachate and odors, which in turn attracts mosquitoes and other insects, negatively impacting human health and the environment. Therefore, effectively treating kitchen waste to achieve its harmlessness, volume reduction, and resource utilization has become an important task in urban waste sorting and resource recovery. Solid-liquid separation can effectively separate the solid and liquid components of kitchen waste, facilitating subsequent sorting, resource utilization, and harmless treatment.

[0003] Existing solid-liquid separation devices for kitchen waste use simple filter structures, resulting in poor separation efficiency. Therefore, it is particularly important to design a solid-liquid separation device for kitchen waste treatment to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing solid-liquid separation devices for kitchen waste use simple filter structures and have poor separation effects, and to propose a solid-liquid separation device for kitchen waste treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a solid-liquid separation device for kitchen waste treatment, comprising a processing box, universal wheels evenly distributed on the bottom of the processing box, an open top, a detachably connected screen plate at the open position, a screen mesh embedded in the screen plate, a locking block installed at the bottom of the screen plate, the locking block being snapped into the processing box, positioning plates symmetrically installed below the screen plate on the inner wall of the processing box, a frame overlapping the positioning plate, a drain port installed at the bottom of the frame, multiple sets of filter screens filled in the frame, a handle fixedly connected to the right end of the frame, an opening installed on the right side of the processing box, a cover plate hinged at the opening position, the cover plate being installed on the processing box by fasteners.

[0006] Preferably, a discharge pipe is installed on the left side of the treatment box, a shut-off valve is installed on the discharge pipe, and a separation cylinder is installed below the positioning plate.

[0007] Preferably, a connecting seat is installed at the bottom of the separating cylinder, and a motor is installed at the bottom of the processing box, with the output end of the motor connected to the connecting seat.

[0008] Preferably, liquid outlet holes are evenly distributed on the side wall and bottom wall of the separation cylinder, and a support ring is fixedly connected to the bottom of the separation cylinder, with convex balls evenly distributed on the bottom of the support ring.

[0009] Preferably, the contact area between the cover plate and the processing box is sealed.

[0010] Preferably, the top of the sieve plate is symmetrically and fixedly connected with handle rings.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, during use, a sieve plate structure is detachably connected to the top of the processing box for initial solid-liquid separation and filtration of mixed kitchen waste. Then, the filtered liquid is conveyed to the frame for secondary filtration, improving the solid-liquid separation effect. After being filtered by multiple sets of filter screens in the frame, small particles of solid waste are filtered out, and the liquid finally enters the separation cylinder. Combined with the motor drive output end driving the separation cylinder to rotate, the liquid after secondary filtration is finally separated into solid and liquid.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] This utility model provides a solid-liquid separation device for kitchen waste treatment, including a processing tank 1. The bottom of the processing tank 1 is evenly distributed with casters 101. The top of the processing tank 1 is open, and a sieve plate 2 is detachably connected to the open position. A screen 201 is embedded in the sieve plate 2. A locking block 202 is installed at the bottom of the sieve plate 2 and is locked onto the processing tank 1. Positioning plates 3 are symmetrically installed on the inner wall of the processing tank 1 below the sieve plate 2. A frame 301 is attached to the positioning plate 3, and a drain outlet 302 is installed at the bottom of the frame 301. The treatment box 1 is filled with multiple sets of filter screens 303. A handle 304 is fixedly connected to the right end of the frame 301. An opening 4 is installed on the right side of the treatment box 1, and a cover plate 401 is hinged to the opening 4. The cover plate 401 is installed on the treatment box 1 by fasteners 402. A discharge pipe 5 is installed on the left side of the treatment box 1, and a shut-off valve 501 is installed on the discharge pipe 5. A separation cylinder 6 is installed below the positioning plate 3, and a connecting seat 602 is installed at the bottom of the separation cylinder 6. A motor 603 is installed at the bottom of the treatment box 1, and the output end of the motor 603 is connected to the connecting seat 602.

[0020] In actual use, the solid-liquid separation equipment for kitchen waste treatment installs the screen plate 2 structure at the open position of the treatment tank 1. The locking block 202 at the bottom of the screen plate 2 is inserted into the treatment tank 1 to limit the screen plate 2 at the open position at the top of the treatment tank 1. Then, kitchen waste is poured into the screen plate 2. Solid waste is retained at the screen mesh 201 of the screen plate 2, while the liquid continues to flow down to the frame 301. It is then filtered again by multiple sets of filter screens 303 in the frame 301. The liquid after secondary filtration flows to the separation cylinder 6 through the drain outlet 302. First, the solid waste retained at the screen mesh 201 is cleaned, and the liquid enters the separation cylinder 6. At this time, the motor 603 starts working and drives the separation cylinder 6 on the connecting seat 602 to rotate. During the rotation of the separation cylinder 6, the liquid flows out through the outlet hole 601 under the action of centrifugal force. The relatively heavy solid waste is retained at the bottom of the separation cylinder 6. Finally, the liquid flows out through the discharge pipe 5 and is discharged by the operator operating the shut-off valve 501. After controlling the start and stop of the discharge pipe 5 and completing one round of kitchen waste treatment, the staff manually removes the fastener 402 to open the cover plate 401 and cleans the solid waste retained in the frame 301 filter screen 303 and the separation cylinder 6 inside the treatment box 1. This avoids the need for subsequent kitchen waste cleaning. The sieve plate 2 structure is detachably connected to the top of the treatment box 1 for preliminary solid-liquid separation and filtration of the mixed kitchen waste. Then, the filtered liquid is conveyed to the frame 301 for secondary filtration to improve the solid-liquid separation effect. The liquid after being filtered by multiple sets of filter screens 303 in the frame 301 removes small particles of solid waste and finally enters the separation cylinder 6. Combined with the motor 603 driving the output end to drive the separation cylinder 6 to rotate, the liquid after secondary filtration is finally separated into solid and liquid. Compared with the conventional solid-liquid separation effect of kitchen waste, the technical solution adopted by this utility model greatly improves the solid-liquid separation effect of kitchen waste. The overall structure is compact, the space layout is reasonable, and it is easy for staff to install and maintain.

[0021] Example 1

[0022] like Figure 1-2 As shown, the sidewalls and bottomwalls of the separation cylinder 6 are evenly distributed with liquid outlet holes 601. A support ring 604 is fixedly connected to the bottom of the separation cylinder 6. The bottom of the support ring 604 is evenly distributed with protruding balls 605. The cover plate 401 is sealed at the contact position with the processing box 1. Handle rings 203 are symmetrically fixedly connected to the top of the sieve plate 2.

[0023] The overall effect of Embodiment 1 is that, in use, the support ring 604 and the multiple sets of convex balls 605 work together to provide effective support for the separation cylinder 6 when it rotates.

[0024] Working Principle: A sieve plate structure is installed at the open position of the processing box. The locking block at the bottom of the sieve plate is inserted into the processing box to limit the sieve plate at the open position at the top of the processing box. Then, kitchen waste is poured into the sieve plate. Solid waste is retained at the screen of the sieve plate, while liquid continues to flow down to the frame position. It is then filtered again by multiple sets of filters in the frame. The liquid after secondary filtration flows to the separation cylinder through the drain port. First, the solid waste retained at the screen is cleaned. The liquid entering the separation cylinder is then started by the motor, which works with the output end to drive the separation cylinder on the connecting seat to rotate. During the rotation of the separation cylinder, the liquid flows out through the liquid outlet under the action of centrifugal force. The relatively heavy solid waste is retained at the bottom position of the separation cylinder. Finally, the liquid flows out through the discharge pipe. The operator operates the shut-off valve to control the start and stop of the discharge pipe. After completing one kitchen waste processing operation, the operator manually removes the fasteners to open the cover plate and cleans the frame filters and the solid waste retained in the separation cylinder inside the processing box to avoid the need for subsequent kitchen waste cleaning.
