Description

Technical Field

[0001] This utility model belongs to the field of waste treatment technology, specifically relating to a solid-liquid separation treatment device for kitchen waste. Background Technology

[0002] Food waste, a major type of waste in the catering industry, is generally a mixture of solid and liquid. When disposing of food waste, the solid and liquid waste is usually mixed and transported to a waste treatment station for further processing. This results in high transportation costs. In addition, the mixed food waste requires a large space for temporary storage and produces odors and affects the environment in hot weather. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a solid-liquid separation treatment device for kitchen waste, which is of moderate size and suitable for timely solid-liquid separation of kitchen waste, in order to address the shortcomings of the prior art.

[0004] The technical solution adopted by this utility model is: a solid-liquid separation treatment device for kitchen waste, including a frame, a funnel-shaped feed inlet fixedly installed on the top of the frame, a J-shaped slag outlet below the feed inlet, the slag outlet being a hollow cavity, and the tail end of the slag outlet being a horizontal cavity, the top of the tail end of the slag outlet being below the feed inlet and communicating with the feed inlet, the bottom of the slag outlet using a perforated plate, the head end of the slag outlet extending upwards out of the frame, and a discharge outlet being opened at the head end of the slag outlet, a pressure plate being connected to the discharge outlet by a joint, a multi-link bracket being installed on the outer wall of the slag outlet near the pressure plate, a tension cylinder being installed on the multi-link bracket, spring brackets being hinged on both sides of the piston rod end of the tension cylinder, the bottom of the spring brackets being rotatably connected to the multi-link bracket, a tension spring being installed on the top of the spring brackets, the other end of the tension spring being connected to the joint connection of the pressure plate, used to control the tension of the pressure plate to seal the discharge outlet;

[0005] A guide groove is opened on the inner side of the top of the tail end of the slag outlet. A connecting plate that slides with the guide groove is installed in the guide groove. A push plate is fixedly connected to one end of the connecting plate inside the slag outlet. The push plate matches the cross section inside the tail end of the slag outlet. A push shaft is installed on the end of the connecting plate away from the push plate.

[0006] A drive motor is installed in the middle of the frame near the pressure plate. A drive gear is installed on the drive shaft of the drive motor, and a driven gear meshes with the drive gear. A crank arm is fixedly installed on the driven gear through a connecting shaft. The other end of the crank arm is rotatably connected to a lower connecting rod. A large arm is installed at the other end of the lower connecting rod. The middle of the large arm is hinged to the end of the lower connecting rod. The upper end of the large arm is connected to a push shaft through an upper connecting rod. A compensation shaft is installed between the lower ends of the large arm. A pressure spring is installed on the compensation shaft. The other end of the pressure spring is fixedly installed on the frame. A pressure cylinder is installed at the bottom of the frame near the compensation shaft. The piston rod end of the pressure cylinder is fixedly connected to the compensation shaft. The tension cylinder and the pressure cylinder are connected through an oil supply pipe.

[0007] The tension of the tension spring on the pressure plate is the same as the pressure of the compression spring on the compensating shaft.

[0008] Preferably, an adjusting spring is also installed between the top of the spring bracket and the frame, and an adjusting handle for adjusting the adjusting spring is also installed.

[0009] Preferably, the multi-link support adopts a parallelogram-shaped four-link structure.

[0010] The beneficial effects of this utility model are as follows:

[0011] (1) The kitchen waste is squeezed by a closed cavity formed by a push plate, a pressure plate and a J-shaped slag outlet to complete the solid-liquid separation of the kitchen waste.

[0012] (2) The pressure of the pressure spring is the same as the tension of the tension spring. When the reciprocating distance generated by the curved arm is greater than the push plate stroke, the insufficient stroke is compensated by the compression of the pressure spring, so that the push plate retracts after a delay, thereby achieving pressure holding and smooth extrusion of the material; at the same time, it can provide protection and buffer space for the mechanical mechanism and extend its service life.

[0013] (3) The pressure of the pressure spring is the same as the tension of the tension spring. When the solid waste is too large and the push plate stroke is blocked, the pressure spring is compressed to compensate. At the same time, the piston rod of the pressure cylinder retracts. Since the pressure cylinder and the tension cylinder are connected, the oil enters the tension cylinder, causing the piston rod of the tension cylinder to extend and drive the top of the spring bracket to move towards the pressure plate, thereby reducing the tension of the tension spring, reducing the pressure of the pressure plate, and allowing the squeezed solid material to be discharged smoothly, so that the whole structure can continue to operate normally and improve the material processing capacity.

[0014] This utility model has an ingenious structural design, which can achieve solid-liquid separation even for larger kitchen waste solids. Furthermore, through the coordinated operation of pressure springs, tension springs, push plates, pressure plates, tension cylinders, and pressure cylinders, it achieves good solid-liquid separation and effectively improves the service life of the equipment.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1 and Figure 2 As shown, the solid-liquid separation treatment device for kitchen waste provided in this embodiment includes a frame 1. A funnel-shaped inlet 2 is fixedly installed on the top of the frame 1. In this embodiment, the inlet 2 is square funnel-shaped. A J-shaped slag outlet 3 is provided below the inlet 2. The slag outlet 3 is a hollow cavity, and the tail end of the slag outlet 3 is a horizontal cavity. The rest of the slag outlet 3 is inclined upward and extends out of the frame 1. The top of the tail end of the slag outlet 3 is located below the inlet 2 and communicates with the inlet 2. The bottom of the slag outlet 3 is a perforated plate, and a slag outlet is opened at the head end of the slag outlet 3. A pressure plate 4 is connected to the slag outlet through a joint. A multi-link bracket 5 is installed on the outer wall of the slag outlet 3 near the pressure plate 4. The multi-link bracket 5 adopts a parallelogram four-link structure. A tension cylinder 6 is installed on the multi-link bracket 5. The tension cylinder 6 is parallel to the head of the slag outlet 3. Spring supports 7 are hinged to both sides of the piston rod end of the tension cylinder 6. The bottom of the spring supports 7 is rotatably connected to the multi-link support 5. A tension spring 8 and an adjusting spring are installed on the top of the spring supports 7. The other end of the tension spring 8 is connected to the joint of the pressure plate 4 to control the tension of the pressure plate 4 to seal the outlet. The other end of the adjusting spring is connected to the frame 1 and is provided with an adjusting handle for controlling the tension of the adjusting spring. That is, through the setting of the tension cylinder 6 and the tension spring 8, the tension spring 8 applies tension to the pressure plate 4, so that the pressure plate 4 is pressed tightly at the outlet. After the piston rod of the tension cylinder 6 continues to extend, the top of the spring supports 7 moves towards the pressure plate 4, thereby causing the tension spring 8 to contract and return, that is, the tension applied by the tension spring 8 to the pressure plate 4 is reduced.

[0021] A guide groove is opened on the inner side of the top of the tail end of the slag outlet 3. A connecting plate 9 is installed in the guide groove and slides with it. A push plate 10 is fixedly connected to one end of the connecting plate 9 inside the slag outlet 3. The push plate 10 matches the cross section inside the tail end of the slag outlet 3. A push shaft 11 is installed on the end of the connecting plate 9 away from the push plate 10.

[0022] A drive motor is installed in the middle of the frame 1 near the pressure plate 4. A drive gear 12 is installed on the drive shaft of the drive motor, and a driven gear 13 meshes with the drive gear 12. A crank arm 14 is fixedly installed on the driven gear 13 through a connecting shaft. The other end of the crank arm 14 is rotatably connected to a lower connecting rod 15. A large arm 16 is installed at the other end of the lower connecting rod 15. The middle part of the large arm 16 is hinged to the end of the lower connecting rod 15. The upper end of the large arm 16 is connected to the push shaft 11 through an upper connecting rod 17. A compensation shaft 18 is installed between the lower ends of the large arm 16. A pressure spring 19 is installed on the compensation shaft 18. The other end of the pressure spring 19 is fixedly installed on the frame 1. A pressure cylinder 20 is installed at the bottom of the frame 1 near the compensation shaft 18. The piston rod end of the pressure cylinder 20 is fixedly connected to the compensation shaft 18. The tension cylinder 6 and the pressure cylinder 20 are connected through an oil supply pipe. The tension of the tension spring 8 on the pressure plate 4 is the same as the pressure of the pressure spring 19 on the compensation shaft 18.

[0023] The crank arm 14, lower connecting rod 15, upper arm 16 and upper connecting rod 17 constitute a linkage mechanism. Through the rotation of the crank arm 14, the lower connecting rod 15 drives the upper arm 16 to reciprocate. The lower end of the upper arm 16 drives the compensating shaft 18 to move horizontally left and right. The upper end of the upper arm 16 drives the push shaft 11 to move horizontally left and right through the upper connecting rod 17. The pressure spring 19 applies pressure to the compensating shaft 18. During normal operation, the compensating shaft 18 remains stationary. The lower connecting rod 15 applies reciprocating force to the middle of the upper arm 16, causing the upper arm 16 to swing around the lower end of the upper arm 16 as the fulcrum, thereby driving the push shaft 11 to move left and right, that is, driving the push plate 10 to reciprocate left and right. At this time, the pushing force of the push plate 10 is the same as the pressure of the pressure plate 4.

[0024] When the push plate 10 is obstructed, the force of the material feedback to the push plate 10 increases. At this time, when the crank arm 14 drives the lower connecting rod 15 to move, it will pull the lower end of the upper arm 16 to move, so that the lower end of the upper arm 16 moves towards the pressure cylinder 20 and the pressure spring 19. That is, the compensating shaft 18 moves towards the pressure spring 19, so that the pressure spring 19 retracts and returns to its original position, compensating for the movement of the upper end of the upper arm 16, thereby ensuring the continuous mechanical movement of the device. At the same time, the compensating shaft 18 pushes back the piston rod of the pressure cylinder 20, so that the oil pressure of the pressure cylinder 20 enters the tension cylinder 6 through the oil pipe. The oil pressure of the tension cylinder 6 increases and pushes out the piston rod of the tension cylinder 6, so that the top of the spring bracket 7 moves towards the pressure plate 4, reducing the tension of the tension spring 8 on the pressure plate 4, making the pressure plate 4 easier to open, thereby discharging some solid material, reducing the pressure of the push plate 10, and thus allowing the push plate 10 to resume normal operation in the next movement.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and utility model concepts provided by the present utility model should be covered within the protection scope of the present utility model.
