Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste treatment technology, specifically a drainage and self-cleaning discharge gate for a hydraulic extruder. Background Technology
[0002] Hydraulic extruders are used in waste treatment to compress and reduce the volume of waste through the huge pressure generated by hydraulic transmission. The operation can be divided into three stages: "feeding-extrusion-discharge".
[0003] In existing hydraulic extruders, liquid in the material is typically drained through sidewall mesh during the extrusion process. However, the drainage hole area is small, resulting in slow drainage speed. In addition, due to prolonged operation of the extruder, the drainage outlet is easily blocked by impurities, further reducing the number of drainage holes. At this time, the water that is not drained will seep out from the gap of the discharge gate, affecting equipment operation and workshop hygiene, thus requiring regular cleaning. Furthermore, the discharge gate of the existing extruder is made of a single piece of steel plate, which has no drainage function itself, and is heavy, expensive, and slow to open and close.
[0004] Based on the above reasons, this utility model provides a drainage and self-cleaning discharge gate for a hydraulic extruder. By improving the structure of the discharge gate, it not only solves the problem of poor drainage in the extruder, but also improves the opening and closing efficiency of the discharge gate itself, and takes into account the cleaning function of the drainage outlet, thus improving the overall working efficiency and quality of the hydraulic extruder. Summary of the Invention
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a drainage and self-cleaning discharge gate for a hydraulic extruder. By improving the structure of the discharge gate, the problem of poor drainage of the extruder is solved, the opening and closing efficiency of the discharge gate itself is improved, and the cleaning function of the drainage outlet is also taken into account, thus improving the working efficiency and quality of the hydraulic extruder as a whole.
[0006] To achieve the above objectives, this utility model provides a drainage and self-cleaning discharge gate for a hydraulic extruder, comprising an outer frame, a discharge gate plate provided on one side of the inner part of the outer frame via a support frame, a transverse reinforcing plate and a longitudinal reinforcing plate provided inside the discharge gate plate, the discharge gate plate being divided into multiple cavities by the transverse reinforcing plate, a cleaning nozzle being provided on the side of the cavity away from the material via a spray pipe, the spray pipe being connected to an external cleaning interface, multiple drainage holes being provided on the panel of the discharge gate plate near the material, and drainage outlets being provided on the transverse reinforcing plate and the lower beam.
[0007] The top of the outer frame is equipped with a hydraulic rod that is connected via a hydraulic rod connector.
[0008] The drainage hole consists of multiple tiny drainage holes.
[0009] The drainage holes are distributed at equal intervals on the discharge gate.
[0010] The horizontal reinforcing plate and the drainage outlet on the lower beam are on the same vertical line.
[0011] The external cleaning interface is connected to an external high-pressure cleaning device via a hose.
[0012] Compared with existing technologies, this utility model improves the internal spatial structure of the discharge gate by modifying it. Following the material extrusion process, the liquid in the material can be forced into the internal cavity of the gate, thus achieving better moisture collection. Furthermore, the reinforcing plate enhances the overall structural strength of the gate. The included cleaning nozzles allow for continuous cleaning of the drainage holes, ensuring smooth drainage. This design also reduces the weight of the discharge gate, lowering costs while maintaining a fast opening and closing speed, thereby improving work efficiency. Attached Figure Description

[0018] The present invention will now be further described with reference to the accompanying drawings.
[0019] See Figures 1-3 This utility model provides a drainage and self-cleaning discharge gate for a hydraulic extruder, including an outer frame 1. A discharge gate 2 is provided on one side of the inner part of the outer frame 1 via a support frame 12. A transverse reinforcing plate 4 and a longitudinal reinforcing plate 14 are provided inside the discharge gate 2. The discharge gate 2 is divided into multiple cavities 10 by the transverse reinforcing plate 4. A cleaning nozzle 7 is provided on the side of the cavity 10 away from the material via a spray pipe 11. The spray pipe 11 is connected to an external cleaning interface 6. Multiple drainage holes 3 are provided on the panel of the discharge gate 2 on the side close to the material. Drainage outlets 5 are provided on the transverse reinforcing plate 4 and the lower beam 13.
[0020] The top of the outer frame 1 is provided with a hydraulic rod 9 connected via a hydraulic rod connection port 8.
[0021] Drainage hole 3 consists of multiple tiny drainage holes.
[0022] The drainage holes 3 are distributed at equal intervals on the discharge gate 2.
[0023] The transverse reinforcing plate 4 and the drainage outlet 5 on the lower beam 13 are on the same vertical line.
[0024] External cleaning interface 6 is connected to an external high-pressure cleaning device via a hose.
[0025] Working principle:
[0026] See Figures 1-3 This invention requires minimal adjustment. The discharge gate 2 is fixed within the outer frame 1, and the hydraulic rod 9 is fixed to the discharge gate 2 via the hydraulic rod connection port 8. The hydraulic rod 9 then drives the discharge gate 2 to open and close left and right. The discharge gate 2 has a cavity 10, which reduces the overall weight of the gate and improves its operating efficiency. The cavity 10 also facilitates the collection of water generated during material compression. A drainage hole 3 is located on the panel near the material side of the discharge gate 2, allowing water generated during compression to drain into the cavity 10 for collection. The cavity 10 contains horizontal reinforcing plates 4 and vertical reinforcing plates 14. Because the drainage holes 3 are strategically located and not situated at the main compression points, the overall strength of the gate is enhanced. The pressure is controlled to ensure that the gate does not deform during the extrusion process. Water in each cavity 10 flows from top to bottom through the drainage holes 3 on the transverse reinforcing plate 4, and is discharged layer by layer into the drainage outlet 3 on the bottom beam 13. Finally, it is collected and discharged out of the equipment. An external cleaning interface 6 is provided on the outside of the discharge gate 2. The external cleaning interface 6 is connected to high-pressure air / cleaning water through a hose. This does not affect the operation of the discharge gate 2, but can clean the drainage holes 3 on the gate. A cleaning nozzle 7 is provided inside the discharge gate 2. High-pressure air / cleaning water enters the spray pipe 11 equipped with the cleaning nozzle 7 through the external cleaning interface 6, and then cleans the drainage outlet 3 on the gate through the cleaning nozzle 7 in each cavity. The cleaned water is then discharged out of the equipment through the drainage outlet 3.
[0027] The above are merely preferred embodiments of this utility model, intended only to aid in understanding the method and core concept of this application. The scope of protection of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.
[0028] This invention solves the problems of existing discharge gates, such as drainage holes located on the side wall or drainage channels being blocked, leading to poor drainage and overflow, requiring manual cleaning which is time-consuming, labor-intensive, unhygienic, and costly. By improving the structure of the discharge gate, it ensures smooth and rapid drainage that is not easily blocked, improves the gate's opening and closing efficiency, requires minimal manual intervention, and saves on production and maintenance costs.
