Description

Technical Field

[0001] This utility model relates to the field of waste vegetable processing technology, specifically to a special screw press for waste vegetable processing. Background Technology

[0002] Vegetable waste, or "leftovers," refers to the remaining leaves and scraps of fresh vegetables that must be removed. During harvesting, some inedible parts of mature fresh vegetables are inevitably removed, such as the roots or incomplete outer leaves of cabbage. Damage also occurs during transportation, requiring the removal of any remaining leaves. Furthermore, some leaves are removed during packaging and distribution, resulting in vegetable waste. The moisture content of fresh vegetable waste is typically between 75% and 90%, sometimes exceeding 95%. Currently, in the field of vegetable waste treatment, existing pressing machines on the market have limited compression strength and insufficient dehydration efficiency. Utility Model Content

[0003] In order to overcome the problems existing in the background art, this utility model provides a special screw press for processing vegetable waste, so as to solve the technical problems of limited extrusion strength and insufficient dehydration efficiency of current vegetable waste presses mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A special screw press for processing vegetable waste includes a frame 1, a pressing box 2, a pressing cylinder 3, a screw pressing rod 4, and a motor 5. The pressing box 2 is mounted on the frame 1, and a water filtration chamber 21 and a slag discharge chamber 22 are respectively arranged from left to right inside the pressing box 2. The pressing cylinder 3 is horizontally arranged, with its right end connected to the right side wall of the water filtration chamber 21 and its right end communicating with the slag discharge chamber 22. The screw pressing rod 4 is installed inside the pressing cylinder 3, with its end rotatably connected to the left end of the pressing cylinder 3, and is driven by the motor 5 mounted on the frame 1. The pressing cylinder 3 is connected to a hopper 6 on the top left side. The side wall of the pressing cylinder 3 located in the water filter chamber 21 is evenly provided with several water filter holes 31. The inner wall of the slag discharge chamber 22 is connected to a connecting rod 7. The left end of the connecting rod 7 is elastically connected to a pressing plate 8. The pressing plate 8 is elastically pressed against the right end outlet of the pressing cylinder 3. The pressing cylinder 3 is a conical structure with a smaller diameter at the left end and a larger diameter at the right end. The diameter of the spiral blades on the spiral pressing rod 4 gradually changes along the inner wall of the pressing cylinder, with the diameter being smaller on the left and larger on the right. The pitch of the spiral blades gradually decreases from left to right.

[0005] Preferably, the end of the connecting rod 7 is provided with a slot 71, and the side wall of the extrusion plate 8 is connected to an insert rod 72. The insert rod 72 is inserted into the slot 71, and a strong spring 9 is connected to the bottom of the slot 71 and the end of the insert rod 72.

[0006] Preferably, a fixing plate 10 is provided at the upper end of the hopper 6, and a spiral push rod 11 is rotatably connected to the bottom of the fixing plate 10. The spiral push rod 11 is connected to a motor 12 installed on the fixing plate 10.

[0007] Preferably, a drain pipe 13 is provided at the bottom of the water filter chamber 21.

[0008] Preferably, the bottom of the slag discharge chamber 22 is provided with a slag outlet 14, and a receiving trough 15 for receiving slag is provided below the slag outlet 14.

[0009] The beneficial effects of this utility model are as follows: This utility model uses a spiral pressing rod 4 with a diameter that gradually increases and a pitch that gradually decreases. The small diameter and large pitch at the front end enable rapid material transmission. As the pitch gradually decreases and the diameter gradually increases in the middle, the material is initially squeezed and some water is discharged. At the rear end, the pitch decreases and the diameter increases, which can form a stronger squeezing force on the material and gradually extract the water. This design allows the spiral pressing rod to gradually increase the pressure on the material. The front end rapidly transmits the material, improving the conveying efficiency of the material. The pressure gradually increases in the rear end, improving the dehydration rate of the material and the pressing efficiency of the material. Attached Figure Description

[0013] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0014] like Figs. 1-3As shown, this utility model provides a special screw press for processing vegetable waste, including a frame 1, a pressing box 2, a pressing cylinder 3, a screw pressing rod 4, and a motor 5. The pressing box 2 is installed on the frame 1, and a water filtration chamber 21 and a slag discharge chamber 22 are respectively arranged from left to right inside the pressing box 2. The pressing cylinder 3 is horizontally arranged, with its right end connected to the right side wall of the water filtration chamber 21 and its right end communicating with the slag discharge chamber 22. The screw pressing rod 4 is installed inside the pressing cylinder 3, with its end rotatably connected to the left end of the pressing cylinder 3, and connected to the motor installed on the frame 1. A transmission connection is provided; a hopper 6 is connected to the top left side of the pressing cylinder 3; a plurality of filter holes 31 are evenly opened on the side wall of the pressing cylinder 3 located in the filter chamber 21; a connecting rod 7 is connected to the inner wall of the right side of the slag discharge chamber 22; a pressing plate 8 is elastically connected to the left end of the connecting rod 7; the pressing plate 8 is elastically pressed against the right end outlet of the pressing cylinder 3; the pressing cylinder 3 is a conical structure with a smaller diameter at the left end and a larger diameter at the right end; the diameter of the spiral blades on the spiral pressing rod 4 gradually changes from small to large on the left side and right side along the inner wall of the pressing cylinder; the pitch of the spiral blades gradually decreases from left to right. In use, chopped vegetable scraps are added to the pressing cylinder 3 from the hopper 6. The scraps are conveyed to the right by the rotating screw press rod 4. Once on the right side of the pressing cylinder 3, the scraps are pressed against the extrusion plate 8. As more and more scraps are conveyed to the right side of the pressing cylinder 3, they are gradually squeezed. The squeezed juice flows out through the filter holes 31 on the side wall of the pressing cylinder 3 and into the filter chamber 21. When the pressure on the extrusion plate 8 increases beyond its elastic deformation pressure, the extrusion plate 8 is forced open, and the remaining residue after the water has been squeezed out is extruded from the gap between the extrusion plate 8 and the end of the pressing cylinder 3. The material is fed into the slag discharge chamber 22. The screw press 4, with its diameter gradually increasing and its pitch decreasing, allows for rapid material transport at the front end (small diameter, large pitch). As the pitch decreases and the diameter increases, the material is initially squeezed and some moisture is removed. At the rear end, the pitch decreases and the diameter increases, creating a stronger squeezing force to gradually extract more moisture. This design allows the screw press to gradually increase the pressure on the material, rapidly transporting it at the front end to improve transport efficiency, and gradually increasing pressure at the rear end to improve dehydration and pressing efficiency.

[0015] The connecting rod 7 has a slot 71 at its end, and the side wall of the pressing plate 8 is connected to an insert rod 72. The insert rod 72 is inserted into the slot 71, and a strong spring 9 is connected to the bottom of the slot 71 and the end of the insert rod 72. The pressing plate 8 is pressed against the right end of the pressing cylinder 3 by the elastic force of the strong spring 9. The vegetable residue is squeezed onto the pressing plate 8 by the pressure of the spiral pressing rod 4, extracting the juice from the vegetable residue. When the pressure of the vegetable residue on the pressing plate 8 exceeds the elastic force of the strong spring 9, the pressing plate 8 is pressed open by the vegetable residue, the strong spring 9 is compressed, and the vegetable residue is squeezed out from the gap between the pressing plate 8 and the end of the pressing cylinder 3 into the slag discharge chamber 22. By pressing the pressing plate 8 against the end of the pressing cylinder 3 by the strong spring 9, the end of the pressing cylinder 3 can be sealed. When the vegetable residue begins to be transported to the right side of the pressing cylinder 3, no pressure has yet been formed between it and the pressing plate 8, preventing the vegetable residue from leaking into the slag discharge chamber 22 from the gap between the pressing plate 8 and the end of the pressing cylinder 3.

[0016] A fixing plate 10 is provided at the upper end of the feeding hopper 6, and a spiral push rod 11 is rotatably connected to the bottom of the fixing plate 10. The spiral push rod 11 is connected to a motor 12 mounted on the fixing plate 10. The motor 12 drives the spiral push rod 11 to rotate and push the leftover vegetables into the pressing cylinder 3, thus preventing the leftover vegetables from clogging.

[0017] A drain pipe 13 is provided at the bottom of the water filter chamber 21.

[0018] The bottom of the slag discharge chamber 22 is provided with a slag outlet 14, and a receiving trough 15 for receiving slag residue is provided below the slag outlet 14.

[0019] Work process: In use, chopped vegetable scraps are added to the pressing cylinder 3 from the hopper 6. The scraps are conveyed to the right by the rotating screw press rod 4. Once on the right side of the pressing cylinder 3, the scraps are pressed against the extrusion plate 8. As more and more scraps are conveyed to the right side of the pressing cylinder 3, they are gradually squeezed. The squeezed juice flows out through the filter holes 31 on the side wall of the pressing cylinder 3 and into the filter chamber 21. When the pressure on the extrusion plate 8 increases beyond the elastic force of the strong spring 9, the extrusion plate 8 is pushed open by the scraps, the strong spring 9 is compressed, and the scrap residue is squeezed out from the gap between the extrusion plate 8 and the end of the pressing cylinder 3. The material is fed into the slag discharge chamber 22. The screw press 4, with its diameter gradually increasing and its pitch decreasing, allows for rapid material transport at the front end (small diameter, large pitch). As the pitch decreases and the diameter increases, the material is initially squeezed and some moisture is removed. At the rear end, the pitch decreases and the diameter increases, creating a stronger squeezing force to gradually extract more moisture. This design allows the screw press to gradually increase the pressure on the material, rapidly transporting it at the front end to improve transport efficiency, and gradually increasing pressure at the rear end to improve dehydration and pressing efficiency.
