[0002] A horizontal decanter centrifuge is a highly efficient centrifugal separation device. Its feeding device is designed to facilitate the separation of different materials. It is widely used in solid-liquid separation of wastewater and sludge, and other industries. Publication number CN216359100U discloses a horizontal decanter centrifuge, relating to the field of centrifuge technology. This application relates to a horizontal decanter centrifuge, also relating to the field of centrifuge technology, aiming to improve the problem of materials adhering to the inner wall of the shell and the outer wall of the drum being difficult to clean, affecting the hygienic environment inside the shell. A horizontal decanter centrifuge includes a shell and a drum rotatably disposed inside the shell; positioning seats are arranged opposite each other at both ends of the shell, surrounding the outer edge of the drum; cleaning components for cleaning the inner wall of the shell and the outer wall of the drum are arranged between the positioning seats; a driving component for driving the positioning seats to rotate is provided on the outer wall of the shell.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1 Please see Figure 1-5This utility model provides a technical solution: a feeding device for a horizontal decanter centrifuge, comprising a centrifuge body 1 and a processing chamber 2. A mounting frame 3 is fixedly installed on the top of the processing chamber 2. A first motor 4 is fixedly installed on the surface of the mounting frame 3. A large gear 5 is fixedly installed at the output end of the first motor 4. A first connecting rod 6 is rotatably connected to the inner surface of the processing chamber 2. A crushing blade 7 and a small gear 8 are fixedly installed on the outer surface of the first connecting rod 6. A feed inlet 9 is opened on the surface of the processing chamber 2. A filter box 10 is fixedly installed at the bottom of the processing chamber 2. A filter plate 11 and a support frame 12 are fixedly installed inside the filter box 10. A second motor 13 is fixedly installed at the bottom of the filter box 10. A second connecting rod 14 is fixedly installed at the output end of the second motor 13. A cleaning tool is fixedly installed on the outer surface of the second connecting rod 14. The bottom of the processing box 2 is provided with a drain port 16. A first connecting pipe 17 is provided on one side of the decanter centrifuge body 1. A second connecting pipe 18 is fixedly installed on the outer surface of the filter box 10. A sealing ring 19 is provided on the inner surface of the second connecting pipe 18 to ensure no leakage during material transmission. The large gear 5 and the small gear 8 mesh with each other, and the power is transmitted through the gear meshing to make the crushing blade 7 operate efficiently, ensuring that the material is fully crushed before entering the decanter centrifuge, reducing large particle impurities, and making the decanter centrifuge perform solid-liquid separation more smoothly. The second connecting rod 14 is rotatably connected to the support frame 12. The rotatable connection ensures that the second connecting rod 14 remains stable when rotating, so that it contacts the filter plate 11 more tightly, effectively removing the residue on the filter plate 11 and avoiding blockage.

[0018] Example 2 Please see Figure 2-3 The first connecting pipe 17 has a positioning groove 20 on its surface, and the second connecting pipe 18 has a positioning post 21 fixedly installed on its surface. The outer surface of the second connecting pipe 18 is slidably connected to an upper clamping plate 22 and a lower clamping plate 23. The outer surface of the upper clamping plate 22 is fixedly installed with a first fixing plate 24. The inside of the first fixing plate 24 is rotatably connected with a fixing bolt 25. The outer surface of the lower clamping plate 23 is fixedly installed with a second fixing plate 26. This allows for quick separation of the filter box 10 from the horizontal screw centrifuge body 1, making regular maintenance more convenient and efficient. The positioning post 21 and the positioning groove 20 are interlocked. Through the interlocking design, the first connecting pipe 17 and the second connecting pipe 18 are precisely aligned, preventing misalignment and improving the stability and sealing of the overall device. The fixing bolt 25 and the second fixing plate 26 are threadedly connected. Through the threaded connection, the upper clamping plate 22 and the lower clamping plate 23 can be quickly tightened and adjusted, facilitating maintenance and replacement, and improving the service life and ease of operation of the device.

[0019] Working Principle: When using this device, the first motor 4 is started first, causing the large gear 5 to rotate, which in turn causes the small gear 8 meshing with it to rotate synchronously. The rotation of the small gear 8 drives the first connecting rod 6 to rotate, and simultaneously the crushing blade 7 begins to rotate at high speed. Then, the raw material can be added through the feed inlet 9 above the processing chamber 2. The raw material entering the feed inlet 9 will have large or hard particles crushed by the rotation of the crushing blade 7, pre-treating the raw material to make solid-liquid separation more efficient, reduce equipment wear, and improve the separation effect. After being crushed by the crushing blade 7, the raw material enters the filter chamber 10 through the drain outlet 16. After being filtered by the filter plate 11, fibrous impurities in the raw material are retained, preventing them from entangled inside the horizontal screw centrifuge body 1 and affecting the separation efficiency. The raw material filtered by the filter plate 11 then enters the second connecting pipe 18... The material is ultimately conveyed to the interior of the decanter centrifuge body 1 through the first connecting pipe 17 for separation. During use, the second motor 13 can be started to rotate the second connecting rod 14, which drives the cleaning frame 15 to periodically clean the surface of the filter plate 11, ensuring that the filter plate 11 will not be blocked and affect the feeding effect. When maintenance is required on the filter box 10 and the decanter centrifuge body 1, the fixing bolt 25 can be rotated to disengage it from the second fixing plate 26, thereby separating the lower clamping plate 23 from the upper clamping plate 22 and canceling the fixing effect on the first connecting pipe 17 and the second connecting pipe 18. After maintenance, the positioning post 21 on the second connecting pipe 18 can be aligned with the positioning groove 20 opened on the first connecting pipe 17 and inserted. Then, the upper clamping plate 22 and the lower clamping plate 23 are clamped on the outside of the first connecting pipe 17 and the second connecting pipe 18, and the fixing bolt 25 is used to reconnect them to the second fixing plate 26 to complete the installation.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
