Embodiment 1

[0014] Embodiment 1, wear-resistant and anti-corrosion composite roller for belt conveyor, such as figure 1 As shown, it includes roller body 1, shaft 2, bearing 3, and bearing housing coaxially arranged. Roller body 1 is made of basalt, shaft 2 is a smooth pull shaft, bearing 3 is a large clearance bearing, and the oil gap is C4 precision is G level. The two ends of the roller body are assembled together with the shaft and the bearing through the bearing seat respectively, and the two ends of the roller body are respectively provided with a sealing cover 4, along the axial direction of the shaft and located inside the bearing, a shaft shoulder retaining ring 5 is installed, and the shaft is internally elastic. A circlip 6, a circlip 7 for holes and a labyrinth seal 8 are arranged in sequence between the outer side of the bearing and the sealing cover, and an outer circlip 9 for the shaft is installed on the outer side of the sealing cover, and the labyrinth seal can be nylon ...

Embodiment 2

[0017] The structure design of the roller is as described in Example 1.

[0018] The preparation method is as follows: the roller body is made of the following raw materials in weight ratio, basalt powder 60%, high-density polyethylene powder resin 30%, acetylene conductive carbon black 3%, graphite powder 4%, antimony trioxide 3% The preparation method includes the following steps: A, basalt is melted at a high temperature of 1350°C, crystallized at 920°C, crushed, and milled to produce 160-mesh basalt powder; B, the basalt powder, high-density polyethylene powdery resin, and acetylene conductive carbon Black, graphite powder and antimony trioxide are mixed according to the above weight ratio; C, the mixed material is transported to the extruder, heated to 250°C, and extruded; D, and then the extruded material is put into the mold , press and form under the pressure of 30MPa through hydraulic press, obtain roller body; E, roll body and bearing, shaft, sealing ring, back-up ri...

Embodiment 3

[0020] The structure design of the roller is as described in Example 1.

[0021] The preparation method is as follows: the roller body is made of the following raw materials in weight ratio, 57% of basalt powder, 35% of high-density polyethylene powder resin, 3% of acetylene conductive carbon black, 3% of graphite powder, and 2% of antimony trioxide The preparation method includes the following steps: A, basalt is melted at a high temperature of 1350°C, crystallized at 900°C, crushed, and milled to produce 150-mesh basalt powder; B, the basalt powder, high-density polyethylene powdery resin, and acetylene conductive carbon Mix black, graphite powder and antimony trioxide according to the above weight ratio; C, transport the mixed material to the extruder, heat it to 200°C, and extrude; D, then put the extruded material into the mold , press molding under the pressure of 25MPa through a hydraulic press to obtain the roller body; E, assemble the roller body with the bearing, the...

Abstract

The invention relates to an idler roller, specifically a wear-resistant and anti-corrosion composite idler roller for a belt conveyor and a preparation method thereof, which solves the problems of many shortcomings of the existing idler roller, including roller bodies, shafts, bearings, bearing seats , sealing cover, the inner side of the bearing is installed with a shoulder retaining ring, the inner elastic ring for the shaft, the elastic ring for the hole and the labyrinth sealing ring are installed between the outer side of the bearing and the sealing cover, and the outer elastic stopper for the shaft is installed outside the sealing cover The ring and the roller body are made of basalt powder, polyethylene powder resin, acetylene conductive carbon black, graphite powder, and antimony trioxide. The basalt is melted, crystallized, and crushed to make basalt powder. The raw materials are mixed according to the weight ratio , heating, pressing and forming to obtain the roll body. Advanced structure, fine manufacturing process, excellent performance, not only has the excellent characteristics of wear resistance, corrosion resistance, dustproof, waterproof, but also has the characteristics of toughness and temperature difference resistance, which improves the working environment; the main economic and technical indicators have reached or exceeded domestic and foreign The advanced level of idlers.

Description

technical field [0001] The invention relates to an idler roller, in particular to a wear-resistant and anti-corrosion composite idler roller for a belt conveyor and a preparation method thereof. Background technique [0002] Belt conveyor is a kind of conveying equipment widely used in mining transportation, electric power, chemical industry, metallurgy, port and other industries. It mainly puts the load on the belt, and transports the material to the required position by driving the directional movement of the belt. , usually under the belt there are multiple cylindrical roller sets supporting the belt. The existing rollers are generally made of metal materials and are cylindrical, while the conveyor belt is generally made of rubber. The friction between the rollers and the conveyor belt during operation makes a lot of noise, and the metal rollers work in an acid-base environment. It is easy to be corroded, and it is easy to produce cutting edges after long-term use, cutti...
