Description

Technical Field

[0001] The utility model relates to the technical field of roller presses, in particular to a high-strength roller for a solid-liquid separation roller machine. Background Art

[0002] The two-roll extruder is a kind of equipment widely used in papermaking, chemical industry, textile, food processing, medicine and other fields. Its main function is to refine or dehydrate the raw materials. The principle is to use the upper roller to apply pressure to the lower roller, and squeeze out the liquid contained in the material passing through the two rollers to achieve the purpose of solid-liquid separation.

[0003] The lower roller of the existing two-roll extruder has a simple internal structure. The supporting structural parts are not precisely processed after welding, and the roller surface is not processed after rolling. The supporting surface cannot be completely fitted with the supporting parts after welding. The roller surface is rolled with ordinary mesh plates, and the roller surface is relatively thin. During the use of the roller, the roller surface is squeezed by the upper roller and subjected to alternating loads, resulting in cracks on the roller surface. The roller cannot work normally and its service life is shortened. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As shown in Figures 1 to 3, the utility model provides a high-strength roller for a solid-liquid separation roller machine, including a main shaft 1, characterized in that roller surface side guards 2 are arranged at both ends of the main shaft 1, a supporting structure 3 is arranged in the roller surface side guard 2, and a roller surface 4 is arranged at one end of the supporting structure 3 away from the main shaft 1.

[0024] 1-3, the supporting structure 3 includes a supporting vertical plate 301, a supporting ring fixing angle iron 302, and a roller surface supporting ring 303; the bottom of the supporting vertical plate 301 is welded to the main shaft 1, and the end of the supporting vertical plate 301 away from the main shaft 1 is welded with a supporting ring fixing angle iron 302, both ends of the supporting ring fixing angle iron 302 are welded to the roller surface side block 2, and a roller surface supporting ring 303 is welded to the outer side of the supporting ring fixing angle iron 302, and the side of the roller surface supporting ring 303 away from the supporting ring fixing angle iron 302 is connected to the bottom of the roller surface 4 by welding.

[0025] By providing a supporting vertical plate 301, a supporting ring fixing angle iron 302, and a roller surface supporting ring 303, the roller surface supporting ring 303 supports the roller surface 4, and the roller surface supporting ring 303 is fixed on the supporting ring fixing angle iron 302. The pressure of the upper roller on the lower roller is distributed to the roller surface supporting ring 303 and the supporting ring fixing angle iron 302, thereby increasing the compressive strength of the roller surface 4 and thus increasing the service life of the roller.

[0026] Furthermore, five groups of support vertical plates 301 are evenly distributed on the main shaft 1. The support vertical plates 301 are precisely processed by wire cutting to keep the size consistent. The support ring fixed angle irons 302 are arranged with six evenly distributed around the main shaft 1. The outer surface of the support ring fixed angle irons 302 is an arc surface that matches the inner arc surface of the roller surface support ring 303.

[0027] The cross-section of the support ring fixing angle iron 302 is designed to be fan-shaped, and the outer arc surface of the fan matches the inner arc surface of the roller surface support ring 303, dispersing the pressure on the roller surface 4 to each support ring fixing angle iron 302, further increasing the compressive strength of the roller surface 4.

[0028] Furthermore, after the roller surface support ring 303 is welded to the support ring fixing angle iron 302, the outer edge is precisely ground to be consistent with the coaxiality of the main shaft 1, and the outer edge of the roller surface support ring 303 fits tightly with the inner side of the roller surface 4.

[0029] The roller surface 4 is welded on the roller surface support ring 303. The roller surface support ring 303 is polished to have a high coaxiality with the main shaft 1, so that the roller surface 4 welded on the roller surface support ring 303 maintains a very high coaxiality with the main shaft 1, so that the roller surface 4 is evenly stressed when the roller is working, thereby improving the compressive strength of the roller surface 4.

[0030] 1-3, the roller surface 4 is rolled and welded on the roller surface support ring 303. The roller surface 4 is made of a stainless steel plate with a thickness of 8 to 13 mm. A plurality of liquid outlet holes 401 are evenly opened on the roller surface 4. The diameter of the liquid outlet hole 401 is 8 mm.

[0031] By using a stainless steel plate with a thickness of 8 to 13 mm to roll the roller surface, it can withstand a larger alternating load. Compared with the traditional process of punching first and then rolling, stretching will occur on the steel body around the liquid outlet hole 401, reducing the strength of the steel plate around the hole. The process of rolling first and then punching is adopted to make the strength of the roller surface 4 at the liquid outlet hole 401 consistent with that of other places, so that the roller surface 4 is not easy to crack, and the liquid outlet holes 401 evenly distributed on the roller surface 4 increase the efficiency of solid-liquid separation.

[0032] How to use

[0033] The working principle and use process of the utility model are as follows: the high-strength roller is composed of a main shaft 1, a roller side block 2, a supporting structure 3 and a roller surface 4. The supporting vertical plate 301 is welded to the main shaft 1 and is precisely processed by wire cutting to keep the size consistent, so that the supporting ring fixing angle iron 302 fixed on the top of the supporting vertical plate 301 maintains a high coaxiality with the main shaft 1, and then the roller surface support ring 303 and the roller surface 4 fixed on the supporting ring fixing angle iron 302 maintain extremely high coaxiality, so that the roller surface 4 is evenly stressed when the roller is working. The roller surface 4 is rolled with a stainless steel plate with a thickness of 8 to 13 mm, which increases the compressive strength of the roller surface 4. The process of first rolling and then punching is adopted, so that the strength of the roller surface 4 at the liquid outlet 401 is consistent with that of other places, so that the roller surface 4 is not easy to crack, and more than 1,000 liquid outlet holes 401 with a diameter of 8 mm are evenly distributed on the roller surface 4, which increases the efficiency of solid-liquid separation.
