Description

Technical Field

[0001] This utility model relates to the technical field of kitchen waste treatment, and in particular to a filter press for kitchen waste. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to a material, causing the liquid to seep out. It is a commonly used solid-liquid separation device and is frequently used in the treatment of kitchen waste.

[0003] A search revealed Chinese patent publication number CN212097663U, which discloses a food waste filter press separator, relating to the field of food waste treatment. The separator includes a filter press box with a cylinder fixedly connected to the top center. One end of the cylinder is fixedly connected to a telescopic rod, and the other end of the telescopic rod is fixedly connected to a pressure plate. A motor is fixedly connected to the rear side of the filter press box, and one end of the motor is fixedly connected to a rotating shaft. A conveying plate is fixedly connected to the surface of the rotating shaft, and the surface of the conveying plate has perforations. Sliding grooves are formed on both sides of the inner wall of the filter press box. This invention uses the cylinder to drive the pressure plate on the telescopic rod to squeeze the food waste on the conveying plate, squeezing out the liquid from the food waste, thereby achieving solid-liquid separation, reducing the growth of harmful bacteria, and improving the efficiency of food waste treatment. The motor drives the conveying plate on the rotating shaft to rotate, facilitating the tilting of the conveying plate to transport the food waste out of the filter press box.

[0004] In existing kitchen waste filter press equipment, the filter residue produced by filter press is generally cake-shaped and hard, which cannot be discharged and processed in a timely manner, and will reduce the working efficiency of the filter press plate and frame unit during long-term use.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a filter press for kitchen waste, making it more industrially valuable. Utility Model Content

[0028] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] like Figures 1-4 As shown, the first embodiment of this utility model is as follows:

[0031] A filter press for food waste has a thrust plate 4 and an end plate 3 installed on the left and right sides of a base 1, respectively. The filter press plate and frame unit, which is mainly used for filtering food waste, is installed between the end plate 3 and the thrust plate 4 and closer to the thrust plate 4. During the filter pressing process, the plate and frame drive module 5 (which can be a manual push rod structure, an electric cylinder, or a motor screw module, etc.) drives the plate and frame drive rod 6, which in turn drives the plate and frame pressing plate 7 to press the multiple filter press plates and frames 8 in the filter press plate and frame unit. After the filter pressing is completed, the reverse process is performed to separate the multiple filter press plates and frames 8 in the filter press plate and frame unit.

[0032] A transparent observation window 17 for real-time observation is installed on the slag collection box 13.

[0033] Multiple filter press frames 8 move in the left-right direction on a support frame 26, which is installed between the end plate 3 and the thrust plate 4 in the left-right direction. Side ears 25 are installed on both the front and rear sides of the filter press frames 8, and sliders 27 are installed at the bottom of the side ears 25. Slide grooves 28, which are distributed in the left-right direction and adapted to the sliders 27, are installed on the support frame 26.

[0034] In addition, a main inlet 10 is installed on the left side of the thrust plate 4. The filter press frame unit includes several filter press frames 8 evenly distributed along the left and right direction. A branch inlet 24 connected to the main inlet 10 is installed in the middle of the filter press chamber 23 on the filter press frame 8. A drain pipe 35 is installed on the bottom front side of the filter press frame 8. A filtrate tank 11 is installed on the base 1 below the drain pipe 35. A filtrate flow channel 12 is installed on one side of the bottom of the filtrate tank 11. The filter press chambers 23 between two adjacent filter press frames 8 are combined into a working chamber. The filtrate to be treated enters the branch inlets 24 of the multiple filter press frames 8 through the main inlet 10. The processed filtrate is then discharged into the filtrate tank 11 below through the drain pipe 35, and then flows out through the pipe connected to the filtrate flow channel 12.

[0035] After the filter press operation has been running for a period of time, the filter residue in the slag collection box 13 needs to be discharged. The screw conveying module 14 (including the screw conveying roller and conveying blades) located in the slag collection box 13 discharges the filter residue from left to right to the filter residue outlet 15 on the right side. The filter residue outlet 15 is designed to bend downwards and to the right, making it easier to discharge the filter residue from the filter residue outlet 15 and let it flow into the slag collection car 18 below.

[0036] During the slag discharge process, a vibration mechanism can be installed at the bottom of the slag collection box 13 to accelerate the slag discharge process. A metal grid structure can also be installed inside the slag collection box 13 on the left side of the filter slag outlet 15 to divide the filter slag for better discharge.

[0037] The slag collection vehicle 18 moves autonomously in the left and right directions on the base 16 below. The moving wheels 30 at the bottom of the slag collection vehicle 18 move within the guide grooves 29 on the base 16, thus guiding the slag collection vehicle 18. During the movement, the slag collection vehicle 18 can be guided by several guide wheels 32 on the front and rear sides, making the movement of the slag collection vehicle 18 more stable.

[0038] The slag collection vehicle 18 enters from the left side of the base 16 and exits from the right side of the base 16. During the process of the slag collection vehicle 18 entering and exiting the base 16, it can be transferred through an external receiving mechanism or a ramp-shaped material platform.

[0039] When the slag collection car 18 transports the material to the receiving station on the right, the gear cylinder 19 drives the gear lever 33, which in turn drives the gear plate 34 to move inward, so that the gear of the slag collection car 18 on the inside can be processed, and then the slag collection car 18 begins to receive the material.

[0040] After a long period of processing, the filter press frame 8 needs to be cleaned by spray cleaning assembly 9. Several spray heads 22 are installed at the bottom of the spray pipe 21, and two adjacent spray heads 22 form a group, which corresponds to two adjacent filter press frame 8. Among the two adjacent spray heads 22, the left spray head 22 is tilted to the left and the right spray head 22 is tilted to the right, which facilitates better cleaning of the left and right filter press frame 8.
