The scraper is in the shape of an arc that fits against the inner wall of the inner cylinder, and a scraper blade is installed on the edge of the scraper.

[0004] The above technical solution uses a scraper to clean the material residue attached to the inner wall of the inner cylinder. However, the scraped material residue will fall into the outer cylinder or the inner cylinder. After dewatering, the dewatering machine may need to be tilted to clean out the residue, which is inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a filter cleaning device for a dehydrator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter screen cleaning device for a dewatering machine, comprising an outer cylinder, a filter screen cleaning device installed at the top of the outer cylinder, and a filter cylinder easy-to-disassemble structure rotatably installed inside the outer cylinder.

[0007] The easily detachable filter cartridge structure includes a rotating rod, which is vertically mounted at the center end of the outer cylinder via a bearing. Limiting grooves are formed around the outer surface of the rotating rod, and limiting blocks are engaged in the limiting grooves. An installation ring is fixedly connected to the outer side of the limiting block, and a filter cartridge is fixedly connected to the outer surface of the installation ring.

[0008] In the above technical solution, the filter cartridge is connected to the limiting groove on the rotating rod through a limiting block. After the cartridge cover is removed, the filter cartridge can be removed by sliding, which makes it convenient to pour out the scraped residue inside.

[0009] As a further preferred embodiment of this technical solution, a connecting cylinder is connected to the bottom side of the outer cylinder via a flange, and a collecting cylinder is connected to the bottom side of the connecting cylinder via a flange. A water outlet pipe is provided below one side of the collecting cylinder, and a valve is provided on the water outlet pipe.

[0010] As a further preferred embodiment of this technical solution, drain pipes are fixedly connected to the through holes at both ends of the bottom side of the outer cylinder, and the drain pipes pass through the outer cylinder and the connecting cylinder and extend to the bottom of the connecting cylinder.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown in this embodiment, a filter screen cleaning device for a dehydrator includes an outer cylinder 1. A connecting cylinder 12 is connected to the bottom side of the outer cylinder 1 via a flange. A collecting cylinder 13 is connected to the bottom side of the connecting cylinder 12 via a flange. A water outlet pipe 14 is provided below one side of the collecting cylinder 13. A valve is provided on the water outlet pipe 14. Drain pipes 11 are fixedly connected to the through holes at both ends of the bottom side of the outer cylinder 1. The drain pipes 11 pass through the outer cylinder 1 and the connecting cylinder 12 and extend to the bottom of the connecting cylinder 12. A filter screen cleaning device 2 is installed at the top of the outer cylinder 1. A filter cylinder easy-to-disassemble structure 3 is rotatably installed inside the outer cylinder 1.

[0028] like Figure 3 and Figure 4As shown, the filter cleaning device 2 includes a cylinder cover 21, which is connected to the outer cylinder 1 via a latch. The latch is used to fasten two items and generally consists of a movable part and a fixed part. The opening and closing of the door / window is achieved by the engagement and disengagement of the movable part and the fixed part. This is existing technology. A handle 22 is fixedly connected to the top side of the cylinder cover 21. An arc-shaped hollow plate 23 is bolted to one end of the cylinder cover 21. The arc-shaped hollow plate 23 passes through the cylinder cover 21 and extends downward into the interior of the outer cylinder 1. An air inlet 24 is provided on the top side of the arc-shaped hollow plate 23. Brush bristles 25 are arranged on both sides of the arc-shaped hollow plate 23 near the inner wall of the outer cylinder 1. An air outlet pipe 26 is arranged in the middle of one end of the inner wall of the outer cylinder 1. The air outlet pipe 26 passes through the arc-shaped hollow plate 23. By installing the filter screen cleaning device 2, when the cylinder cover 21 is installed on the outer cylinder 1, the bristles 25 contact the filter screen on the side wall of the filter cylinder 35. When centrifugally dewatering, the bristles 25 contact the filter screen and scrape off the adhering residue. At the same time, the air compressor blows the gas out from the air outlet pipe 26, which can blow out the residue stuck in the filter holes and improve the filtration effect of the filter cylinder. The working principle of the air compressor is to compress the air into the high-pressure air tank and then release it to meet the pressure requirements of various industrial fields.

[0029] like Figure 3 and Figure 5 As shown, the easy-to-disassemble filter cartridge structure 3 includes a rotating rod 31, which is vertically mounted at the center of the outer cylinder 1 via a bearing. Limiting grooves 32 are formed around the outer surface of the rotating rod 31, and limiting blocks 33 are engaged within each limiting groove 32. An installation ring 34 is fixedly connected to the outer side of each limiting block 33, and a filter cartridge 35 is fixedly connected to the outer surface of the installation ring 34. A motor 36 (model YBX3) is mounted on one side of the outer surface of the connecting cylinder 12. The output end of the motor 36 is connected to the end of the rotating rod 31 that protrudes through it via a conveyor belt. Through the easy-to-disassemble filter cartridge structure 3, the filter cartridge 35 is connected to the limiting grooves 32 on the rotating rod 31 via the limiting blocks 33. When the cylinder cover 21 is removed, the filter cartridge 35 can be slidably removed, facilitating the emptying of scraped debris and cleaning of the outer cylinder 1. Additionally, the collected cylinder 13 can be disassembled to clean up any fallen debris. This method is significantly more convenient for disassembly and cleaning compared to existing fixed installation methods.

[0030] This utility model provides a filter cleaning device for a dewatering machine. The specific working principle is as follows: The motor 36 causes the rotating rod 31 to rotate, which in turn causes the filter cylinder 35 to rotate for centrifugal dewatering. During the dewatering process, the bristles 25 contact the inner wall of the filter cylinder 35 and scrape off the attached residue through friction. At the same time, an external air compressor delivers gas to the arc-shaped hollow plate 23 and discharges it through the air outlet pipe 26. The blown air blows out the residue stuck in the filter holes of the filter cylinder 35. The dewatered water first enters the outer cylinder 1 and then enters the collection cylinder 13 through the drain pipe 11. The valve on the water outlet pipe 14 can be opened to drain the water. After the centrifugal dewatering is completed, the cylinder cover 21 can be opened by locking, and the filter cylinder 35 can be pulled out by sliding. This not only facilitates the handling of materials but also facilitates the dumping of scraped residue and the cleaning of residue blown into the outer cylinder 1. At the same time, the collection cylinder 13 can be separated by disassembling the flange on the collection cylinder 13 to clean up the fallen residue.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
