DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-4 An embodiment of the utility model discloses a roller structure of an inclined screen separator. Specifically, the roller comprises a roller body 1 and a roller shaft 2. The roller body 1 is fixedly mounted on the outer side of the roller shaft 2.

[0027] The roller shaft 2 includes a connecting portion 21, and a neck 22 for matching with a bearing seat is fixed at both ends of the connecting portion 21. A fixing portion 23 is fixedly installed at the end of one of the necks 22. The fixing portion 23 is used to connect with an external driving device, such as being fixed to the motor shaft end through a coupling to complete the rotation drive of the entire roller. In addition, the connecting portion 21, the neck 22 and the fixing portion 23 are an integrated structure. By adopting an integrated structural design, the connection stability between the roller body 1 is improved. Compared with the current split welding method, the problem of breakage is greatly avoided and the durability is improved.

[0028] The outer circumferential portion of the roller body 1 has a plurality of overflow holes 11, and the overflow holes 11 are used to allow the squeezed water to flow into the collection chamber when cooperating with the upper roller to squeeze feces. At least one supporting assembly 3 is provided between the roller body 1 and the connecting portion 21.

[0029] In some embodiments, the roller body 1 in the utility model includes an outer peripheral portion 12 and two end portions 13, and the two end portions are respectively fixed at the two end openings of the outer peripheral portion 12. Specifically, in this embodiment, the outer peripheral portion 12 and the two end portions 13 are welded into shape, wherein overflow holes 11 are provided on the end surfaces of the outer peripheral portion 12 and the end portions 13.

[0030] On the basis of the above embodiments, in this embodiment, a first through hole 131 and a second through hole 132 are respectively provided on the end faces of the two ends 13, the diameter of the first through hole 131 is larger than the diameter of the second through hole 132, and the second through hole 132 is adapted to the outer diameter of the connecting portion 21. Obviously, those skilled in the art know that the shape of the second through hole 132 should be the same as the shape of the connecting portion 21. In this embodiment, the connecting portion 21 is preferably designed as a cylindrical structure, and the second through hole 132 is designed as a circular hole. In this embodiment, the first through hole 131 is also set as a circular hole. In other embodiments, the first through hole 131 can also be set as a rectangular hole, a triangular hole or a special-shaped hole. In this embodiment, its minimum width should be larger than the diameter of the second through hole 132.

[0031] Furthermore, in the present embodiment, a positioning protrusion 24 is further installed on the outer side of the connecting portion 21, and the positioning protrusion 24 is sleeved and adapted with the first through hole 131. The positioning protrusion 24 is designed to locate the installation position of the fixed roller body 1. During the specific installation, the roller body 1 is sleeved on the outer side of the roller shaft 2, and the roller body 1 is pushed inward until the first through hole 131 of the roller body 1 is sleeved on the outer side of the positioning protrusion 24, and the sides of the two are kept flush. At this time, the required welding position of the roller body 1 is reached, and the positioning protrusion 24 and the roller body 1, as well as the connecting portion 21 and the roller body 1 are welded separately by welding equipment.

[0032] In order to increase the flow capacity of the extruded liquid, the overflow hole 11 in this embodiment is a frustum hole whose diameter gradually increases from the outer surface of the roller body 1 to its inner surface. The design of the frustum hole can provide a larger liquid discharge flux while ensuring the strength adjustment of the roller body 1. After extrusion, the liquid will drip downward, and the overflow hole 11 below the roller body 1 will drain water at this time. Since the inner diameter of the overflow hole 11 reaches, the amount of liquid entering can be increased, thereby improving the liquid discharge effect.

[0033] It should be noted that the roller body 1 described in the embodiment of the utility model is a stainless steel part. Specifically, the stainless steel part described in the embodiment can be selected from materials with excellent corrosion resistance and high strength such as 316L or 2205. These materials can maintain stable performance in a complex working environment, effectively reduce the wear of the roller body 1, so as to improve the separation efficiency and extend the service life of the roller shaft. In addition, in the embodiment, the above-mentioned roller shaft 2 can be made of silicon-manganese alloy, and its excellent weldability is utilized to provide great convenience for the welding between the roller body 1 and the roller shaft 2.

[0034] In some embodiments, the support assembly 3 in the utility model includes an inner ring 31, an outer ring 32 and a plurality of support arms 33, wherein the outer ring 32 is fixedly mounted inside the roller body 1, and the inner ring 31 is sleeved on the outside of the connecting portion 21, wherein a plurality of the support arms 33 are circumferentially distributed between the inner ring 31 and the outer ring 32, and the support arms 33 are designed to support the middle portion of the roller body 1. Since the roller body 1 is a hollow structure, after supporting the inner middle portion thereof, its deformation resistance is stronger and its durability is improved. Specifically, in this embodiment, the outer ring 32 is fixed to the inner wall of the roller body 1 by welding, and can be integrally plugged into the outer side of the connecting portion 21 along with the roller body 1 during installation.

[0035] On the basis of the above-mentioned embodiment, in the utility model, a circumferential positioning component is further arranged between the inner ring 31 and the connecting portion 21, and the arranged circumferential positioning component is used to enhance the follow-up performance between the middle portion of the roller body 1 and the connecting portion 21, improve the rotation stability of the roller body 1, reduce the rotation stress between the connecting portion 21 and the two ends of the roller body 1, and improve the durability of the roller shaft.

[0036] Exemplarily, the circumferential positioning component includes at least one block 25 fixed on the outside of the connecting portion 21, and an avoidance hole 34 is provided on the outside of the inner ring 31 and is plugged into the block 25. It should be noted that in this embodiment, the height of the block 25 is smaller than the minimum inner diameter or width of the first through hole 131 to avoid interference with the installation of the roller body 1.

[0037] In summary, the utility model adopts an integral roller shaft 2 to be connected to the roller body 1, which can greatly improve the force stability and durability of the entire roller shaft and reduce the risk of breakage due to split welding. Secondly, the utility model also designs the roller body 1 as a stainless steel part, which utilizes its own material characteristics to maintain stable performance in a complex working environment, effectively reducing the wear of the roller body 1, thereby improving the separation efficiency, extending the service life of the roller shaft, and further optimizing the durability and applicability of the existing roller shaft.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
