Description

Technical Field

[0001] The present invention belongs to the technical field of separating and filtering sewage in kitchen waste, and particularly relates to a kitchen waste treatment system. Background Art

[0002] Kitchen waste mainly includes sewage and residues such as vegetables containing sewage. Before the sewage is input into the sewage treatment tank, the residues need to be separated from the sewage to prevent the residues from further decaying in the sewage treatment tank and affecting the efficiency of sewage treatment. The currently commonly used separation and filtration method is to use a horizontally or inclined spiral pusher to push the kitchen waste from one end to the other end, and during the pushing process, a cylindrical filter net sleeved outside the spiral pusher is used to separate the sewage from the residues. The sewage automatically drains out through the filter net, while the residues are retained inside the filter net and are pushed out from the end of the filter net by the spiral pusher, so as to achieve the purpose of separating the residues from the sewage. Affected by gravity, the part of such a separation device that separates the sewage residues is mainly concentrated at the bottom of the filter net. Similarly, under the action of gravity, the residues usually adhere to the bottom of the filter net and are pushed towards the discharge end under the action of the spiral push rod; thus, both sides and the top of the filter net are in an idle state for a long time, and since the bottom is involved in the separation work of sewage and residues for a long time, the bottom of the filter net is extremely easy to be blocked, and over time, the separation efficiency will be affected and the drainage speed of the sewage will be reduced. Summary of the Invention

[0003] To solve the deficiencies of the prior art, the present invention provides a kitchen waste treatment system, which can effectively prevent local blockage of the filter net, has a relatively fast drainage speed, and can further reduce the residual sewage in the residues.

[0004] To achieve the purpose of the present invention, the following scheme is proposed: A kitchen waste treatment system includes: a vertically arranged cylindrical pipe, inside which a spiral push rod is coaxially arranged. A discharge pipe is communicated with the side wall at the upper end of the cylindrical pipe, and a reduction motor for driving the spiral push rod to rotate is arranged at the top of the cylindrical pipe. A storage bin with a larger inner diameter is coaxially arranged at the lower end of the cylindrical pipe, and a feed pipe is communicated with its side wall. A drain pipe is coaxially arranged at the lower end of the storage bin. A filter cylinder with a circular tube structure is coaxially arranged at the lower end of the spiral push rod, and the filter cylinder penetrates through the storage bin, and the inside of the filter cylinder is communicated with the drain pipe; A continuous spiral push plate is wound around the outside of the filter cylinder and the spiral push rod, and side enclosing plates are arranged upward at the edges of the spiral push plates corresponding to the filter cylinder; An extension pipe extends from the lower end of the cylindrical pipe into the storage bin, and it is sleeved outside the spiral push plate. The lower end of the extension pipe extends to the middle of the communication port between the feed pipe and the storage bin, and an annular bin is formed between the outside of the extension pipe and the upper end inside the storage bin.

[0005] The beneficial effects of the present invention are as follows: 1. The filter cartridge of this solution is always in a rotating state, effectively preventing excessive local working load, which may cause blockage of the overloaded parts, and enabling the filter cartridge to maintain the consistency of the filtration rate at all circumferential parts for a long time. 2. On the other hand, this solution makes the filter cartridge move actively relative to the residue by rotating, so that the filter cartridge actively impacts the residue, and the impact can effectively prevent the mesh from being blocked.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will describe the embodiments of the present invention in detail with reference to the drawings. However, the embodiments described herein are only part of the embodiments of the present invention, not all of them.

[0013] As Figure 1 、 Figure 2 and Figure 4 shown, a kitchen waste treatment system includes: a vertically arranged cylindrical tube 11, inside which a spiral push rod 21 is coaxially arranged. A discharge pipe 111 is communicated with the side wall at the upper end of the cylindrical tube 11, and a reduction motor 12 for driving the spiral push rod 21 to rotate is arranged at the top of the cylindrical tube 11.

[0014] Specifically, as Figure 2 、 Figure 4As shown, a storage bin 13 with an inner diameter larger than that of the cylindrical tube 11 is coaxially provided at the lower end of the cylindrical tube 11. A feed pipe 131 is communicated and provided on its side wall. A drain pipe 14 is coaxially provided at the lower end of the storage bin 13. A filter cylinder 22 with a circular tube structure is coaxially provided at the lower end of the spiral push rod 21. The filter cylinder 22 is inserted into the storage bin 13, and the inside of the filter cylinder 22 is communicated with the drain pipe 14.

[0015] As a preferred structure, the inner diameter of the filter cylinder 22 is less than or equal to the inner diameter of the drain pipe 14 to ensure the smooth flow of the filtered sewage.

[0016] As a preferred solution, the inner diameter of the filter cylinder 22 is larger than the outer diameter of the spiral push rod 21.

[0017] Specifically, as Figure 2 、 Figure 4 shown, a continuous spiral push plate 23 is wound around the outside of the filter cylinder 22 and the spiral push rod 21. The edge of the spiral push plate 23 corresponding to the filter cylinder 22 is provided with a side enclosure plate 231 upwards, which can effectively gather the residues on the spiral push plate 23.

[0018] Specifically, as Figure 2 、 Figure 4 shown, an extension pipe 112 is extended and provided towards the inside of the storage bin 13 at the lower end of the cylindrical tube 11. The extension pipe 112 is sleeved outside the spiral push plate 23. The lower end of the extension pipe 112 extends to the middle of the communication port between the feed pipe 131 and the storage bin 13. An annular bin 132 is formed between the outside of the extension pipe 112 and the upper end inside the storage bin 13.

[0019] When separating and filtering kitchen waste, start the reduction motor 12 to drive the spiral push rod 21 and the filter cylinder 22 to rotate together. Feed the kitchen waste from the feed pipe 131 into the storage bin 13. The sewage in the kitchen waste will flow from the meshes on the side wall of the filter cylinder 22 into the inside of the filter cylinder 22, and then naturally fall and drain from the drain pipe 14, so as to achieve the purpose of separating and filtering sewage. A part of the residue will enter the spiral push plate 23 from the lower end of the extension pipe 112, and under the driving action of the spiral push plate 23, enter the extension pipe 112, and move upward along the extension pipe 112 into the cylindrical pipe 11, and finally be discharged through the discharge pipe 111. During the rising process of the residue, the sewage inside will continuously drip, thereby improving the sewage discharge rate. This solution can not only ensure the continuous discharge of sewage, improve the sewage discharge efficiency of kitchen waste, but also enable the residue to climb through the inside of the extension pipe 112 and the cylindrical pipe 11, continuously discharging the sewage contained in the residue, and effectively reducing the water content of the residue. Another part of the residue that is not immediately carried away by the spiral push plate 23 will be temporarily stored in the storage bin 13 under the driving force of the rotating filter cylinder 22, and evenly distributed in the annular bin 132 along the circumference to prevent the residue from blocking the connection port between the feed pipe 131 and the storage bin 13. And the residue stored in the storage bin 13 will continuously move in the storage bin 13 under the driving of the filter cylinder 22 and its external spiral push plate 23, so as to improve the sewage discharge rate. During the continuous rotation of the filter cylinder 22, the residue stored in the storage bin 13 will eventually enter the extension pipe 112 and be discharged from the discharge pipe 111 at the upper end of the cylindrical pipe 11 under the action of the spiral push rod 21.

[0020] Compared with the horizontal or inclined sewage filtration solutions, the filter cylinder 22 is constantly rotating in this solution, effectively preventing the problem of blockage of the overloaded part caused by excessive local working load, and enabling the filter cylinder 22 to maintain the consistency of the filtration rate effect at all circumferential parts for a long time. On the other hand, in this solution, the filter cylinder 22 actively moves relative to the residue by rotating, so that the filter cylinder 22 actively impacts the residue, and the impact can effectively prevent the meshes from being blocked.

[0021] Preferably, the feed pipe 131 is connected to the middle or upper end of the storage bin 13 to extend the contact range between the filter cylinder 22 and the sewage, improve the filtration efficiency, and effectively reduce the filtration amount at the lower end of the filter cylinder 22, reducing the risk of blockage at the lower end of the filter cylinder 22.

[0022] Preferably, as Figure 2 、 Figure 4 shown, the outer side of the filter cylinder 22 extends outward with a paddle 24, which is located below the extension pipe 112, and multiple paddles 24 are provided along the axial and circumferential directions of the filter cylinder 22. The paddle 24 can effectively drive the residue in the storage bin 13 to rotate, make the residue distribution more uniform, prevent the blockage of the feed pipe 131, and at the same time can improve the sewage discharge rate when the residue moves.

[0023] Further preferably, as Figure 2 , Figure 4 shown, a blade is provided on one side of the paddle 24 facing the rotation direction of the filter cartridge 22 for the purpose of cutting and refining the residue to prevent the residue from getting stuck inside the treatment system.

[0024] Preferably, as Figure 4 shown, through holes are provided on the spiral push plate 23 to increase the dripping speed of the sewage during the rising process of the residue, thereby reducing the water content of the residue.

[0025] Preferably, the pitch of the spiral push plate 23 at the upper end of the spiral push rod 21 is smaller than the pitch of the spiral push plate 23 at the lower end of the spiral push rod 21, so as to form extrusion on the residue rising to the upper end of the cylindrical tube 11 to further reduce the water content of the residue.

[0026] Preferably, as Figure 1 shown, the discharge pipe 111 is arranged along the tangent direction of the rotation direction of the spiral push rod 21 to facilitate the residue to smoothly enter the discharge pipe 111; a baffle 232 is provided at the top end of the spiral push plate 23, the baffle 232 is arranged along the radial direction of the spiral push rod 21, and the top surface of the baffle 232 is lower than the bottom surface of the inner hole of the discharge pipe 111. Before discharging, the residue is pushed and accumulated at the upper end of the cylindrical tube 11 by the spiral push plate 23. The baffle 232 is driven by the rotation of the spiral push rod 21 to stir the accumulated residue along the circumference. During the stirring process, the residue can smoothly enter the discharge pipe 111 through the connection between the discharge pipe 111 and the cylindrical tube 11, thus achieving the purpose of smooth discharging.

[0027] Preferably, as Figure 2 , Figure 3 shown, a pressing head 3 in the shape of a circular ring structure is provided at the top of the cylindrical tube 11. The pressing head 3 is sleeved outside the rod body at the upper end of the spiral push rod 21. A pressure spring 31 is provided above the pressing head 3. The pressure spring 31 is in a compressed state and still has a compression stroke. Therefore, the pressure spring 31 exerts a downward pressure on the pressing head 3 and can be further compressed under the action of an upward thrust. When the pressing head 3 is at the lowest position, its side wall shields the connection between the discharge pipe 111 and the cylindrical tube 11; after the pressing head 3 and the pressure spring 31 are provided, when the residue is accumulated at the upper end of the cylindrical tube 11 by the spiral push plate 23, it is necessary for the spiral push plate 23 to form an upward thrust on the accumulated residue to push the pressing head 3 upward, so that the connection between the discharge pipe 111 and the cylindrical tube 11 is exposed below the pressing head 3. At this time, the accumulated residue can enter the discharge pipe 111. During this process, the residue will be further compressed, so that the sewage in the residue is further discharged, and the water content of the residue is further reduced; after regular cleaning or after each use, the pressing head 3 can be actively moved upward to open the connection between the discharge pipe 111 and the cylindrical tube 11, so that the remaining residue in the cylindrical tube 11 can be discharged.

[0028] Further preferably, as Figure 2 , Figure 3 shown, at least one guide rod 32 is vertically provided at the top of the indenter 3, and a disc 321 is provided at its top. The upper end of the guide rod 32 passes upward through the top of the cylindrical tube 11, and the disc 321 is located on the top surface of the cylindrical tube 11. A threaded tube 15 sleeved outside the disc 321 is provided on the top surface of the cylindrical tube 11. A threaded sleeve 16 is sleeved outside the threaded tube 15. The top of the threaded sleeve 16 is a closed structure, and a compression spring 31 is provided inside the threaded tube 15 and the threaded sleeve 16. Specifically, the bottom surface of the compression spring 31 abuts against the top surface of the disc 321, and the top surface of the compression spring 31 abuts against the inner top surface of the threaded sleeve 16. By rotating the threaded sleeve 16, the compression amount of the compression spring 31 can be adjusted, thereby adjusting the pressure generated by the compression spring 31 on the indenter 3, and thus changing the magnitude of the upward thrust required to push the indenter 3 upward by the residue. In this way, the compression degree when the residue is discharged can be adjusted. When the threaded sleeve 16 is adjusted downward, the pressure on the compression spring 31 can be increased, thereby increasing the thrust required to push the indenter 3 upward when the residue is discharged, and then increasing the compression amount of the residue, further reducing the residual sewage in the residue; on the contrary, if the threaded sleeve 16 is adjusted upward, the pressure generated by the compression spring 31 can be reduced, ultimately reducing the upward thrust required when the residue is discharged, and reducing the compression of the residue.

[0029] As a preferred structure, there are a pair of guide rods 32, threaded sleeves 16 and threaded tubes 15, and they are distributed in a circumferential array.

[0030] As a preferred structure, as Figure 2 shown, the bottom of the indenter 3 is a conical structure with its apex facing downward, so as to guide the residue outward and make it easier for the residue to enter the discharge pipe 111.

[0031] The above are only the preferred embodiments of the present invention, and do not represent the only or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all fall within the scope of protection of the present invention.
