Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belt cleaners, and particularly to an efficient energy-saving cleaning device for a belt conveyor. Background Art

[0002] A belt conveyor is an important device in a coal conveying system. It can form a material conveying process on a certain conveying line from the initial feeding point to the final discharging point. It has the characteristics of multiple lines, long transportation distance, and mostly open-air, underground, and enclosed layouts.

[0003] During the process of a belt conveyor transporting materials, residual materials are easily adhered to the conveyor belt, which can easily cause problems such as conveyor belt deviation and inaccurate weighing of belt scales. Therefore, cleaning devices are provided on belt conveyors to remove the adhered materials. The existing cleaning devices for belt conveyors usually adopt scraper types to scrape the particulate materials on the conveyor belt. However, the scraper scrapes against the cold-bonded joints of the conveyor belt and the uneven edges of the repaired parts of the conveyor belt, which is likely to cause abnormal wear of the scraper or the turning up of the conveyor belt joints and repaired parts, easily causing the conveyor belt to jump during transportation, and also easily causing overall wear and fracture of the conveyor belt over a long time; at the same time, the scraper is also easily worn, resulting in poor cleaning of the conveyor belt cleaner, causing the return stroke of the working surface of the conveyor belt to be easily adhered with materials, resulting in serious material adhesion on the rollers and idlers, further causing conveyor belt deviation, spillage, dust, inaccurate metering, and difficult cleaning of the spilled materials, which will consume a large amount of manpower, material resources, and financial resources, and frequent replacement of the conveyor belt further increases the transportation cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide an efficient energy-saving cleaning device for a belt conveyor to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An efficient energy-saving cleaning device for a belt conveyor includes a support and a roller rotatably installed on the support, and the roller is driven to rotate by a driving source installed on the support;

[0007] The rotation direction of the roller is opposite to the running direction of the conveyor belt;

[0008] A two-way threaded cleaning part is formed on the roller, and the two-way threaded cleaning part is symmetrically arranged with a left spiral end face and a right spiral end face from the middle of the roller to both ends; the left spiral end face and the right spiral end face are flat.

[0009] The high-efficiency energy-saving cleaning device for the belt conveyor as described above: The driving source includes a speed reducer fixedly installed on the support. The speed reducer includes a servo motor and a reducer connected to the servo motor. The output shaft of the reducer is connected to the rotating shaft of the roller through a coupling.

[0010] The high-efficiency energy-saving cleaning device for the belt conveyor as described above: Bearing seats are symmetrically arranged on the support, and the bearing seats are rotatably connected to the rotating shaft of the roller.

[0011] The high-efficiency energy-saving cleaning device for the belt conveyor as described above: The roller is arranged in a hollow structure.

[0012] The high-efficiency energy-saving cleaning device for the belt conveyor as described above: The end widths of the left spiral end face and the right spiral end face are 30 mm.

[0013] The high-efficiency energy-saving cleaning device for the belt conveyor as described above: The pitches of the left spiral end face and the right spiral end face are 45 mm.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] The rotation direction of the roller driven by the driving source is opposite to the running direction of the return conveyor belt, and the roller is in line contact with the conveyor belt surface. The roller generates a two-way lateral expansion force, thereby brushing off the materials adhered to the conveyor belt surface, achieving the purpose of cleaning, and playing a role in centering and preventing deviation.

[0016] The roller of the present utility model is made of polyurethane material and consists of left and right spiral end faces. When the roller rolls on the conveyor belt surface to clean the adhered materials, it will not cause scraping or abrasion to the uneven parts of the cold joints or repaired parts of the conveyor belt, reducing the wear of the conveyor belt to a certain extent and improving the service life of the conveyor belt.

[0021] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. Like reference numerals in the drawings denote functionally identical or similar elements. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0022] As used herein, the term "exemplary" means "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as superior or better than other embodiments.

[0023] In addition, for a better description of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can be implemented without some of these specific details. In some instances, methods, means, and elements well known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0024] Please refer to Figures 1 to 3 , in an embodiment of the present utility model, an efficient energy-saving cleaning device for a belt conveyor includes a roller 4, a support 5, and a bidirectional threaded cleaning part.

[0025] Specifically, please refer to Figure 1 , including;

[0026] The support 5 and the roller 4 rotatably mounted on the support 5, and the roller 4 is driven to rotate by a drive source mounted on the support 5;

[0027] The rotation direction of the roller 4 is opposite to the running direction of the conveyor belt;

[0028] A bidirectional threaded cleaning part is formed on the roller 4, and the bidirectional threaded cleaning part is in line contact with the end face of the conveyor belt.

[0029] Specifically, in this embodiment, when using the efficient energy-saving cleaning device for a belt conveyor of the present utility model, the rotation direction of the roller 4 is driven by a drive source to be opposite to the running direction of the return conveyor belt, and the roller 4 is in line contact with the belt surface of the conveyor belt. The roller 4 generates a bidirectional lateral expansion force, thereby brushing off the materials adhered to the belt surface, achieving thorough cleaning, and playing a role in centering and preventing deviation.

[0030] It should be noted that the bidirectional threaded cleaning part on the roller 4 is made of a more efficient and durable polyurethane material, or both the roller 4 and the bidirectional threaded cleaning part thereon are made of a more efficient and durable polyurethane material, which can reduce the wear on the conveyor belt and increase the service life of the conveyor belt.

[0031] Please refer to Figure 1, the driving source includes a speed reducer 1 fixedly installed on the support 5. The speed reducer 1 includes a servo motor and a reducer connected to the servo motor. The output shaft of the reducer is connected to the rotating shaft of the roller 4 through a coupling 2.

[0032] Bearing seats 3 are symmetrically arranged on the support 5, and the bearing seats 3 are rotatably connected to the rotating shaft of the roller 4.

[0033] Preferably, the height of the support 5 can be adjusted, so as to change the distance between the roller 4 and the conveying end face of the conveyor belt during use, ensuring that after the roller 4 is worn, the height of the roller 4 is adjusted to ensure that the roller 4 always fits the conveyor belt, without frequently replacing the roller, thus saving costs.

[0034] Specifically, the support 5 includes legs in contact with the ground or the workbench and a receiving frame slidably installed on the legs. The speed reducer 1 and the roller 4 are both installed on the receiving frame. Of course, there are also fixing members for fixing the receiving frame at a certain position on the legs. The fixing members include but are not limited to bolts, pins, etc., and can be specifically selected according to actual needs. This embodiment does not make specific limitations on this.

[0035] Among them, a power control box is arranged on the support 5. The power control box can control the servo motor and the driving member on the conveyor belt at the same time to realize the interlocking start and stop of the conveyor belt and the roller 4.

[0036] Expanding on this, start the servo motor to work. The frequency of the rotation of the servo motor can be adjusted through the reducer, so as to play a role in reducing the speed conversion of the rotation speed of the output shaft of the servo motor. After deceleration, the rotation of the roller 4 is driven through the coupling 2 to meet the requirement of the rotation of the roller 4. Under the action of the double-thread cleaning part, the adhesion on the conveyor belt surface is brushed off to achieve the cleaning purpose.

[0037] Exemplarily, a variable-frequency servo motor can be selected for the servo motor, and the frequency of the variable-frequency servo motor is changed according to the adhesion degree of the dust on the conveyor belt.

[0038] Preferably, the roller 4 is arranged in a hollow structure, mainly to reduce the weight of the roller 4 itself, so that the power consumed by the servo motor when the roller 4 rotates is reduced.

[0039] Specifically, the double-thread cleaning part is symmetrically arranged with a left spiral end face and a right spiral end face from the middle of the roller 4 to both ends.

[0040] It should be noted that the end face of the double-thread cleaning part is planar, that is to say, the end face of the double-thread cleaning part has a certain width, so that when the double-thread cleaning part contacts the end face of the conveyor belt, it is a line contact, so as to increase the contact area between the double-thread cleaning part and the conveyor belt. When the roller 4 rolls on the conveyor belt surface to clean the adhered materials, it will not scrape and wear the uneven parts of the cold joint or repair port of the conveyor belt. At the same time, the polyurethane elastomer has properties between plastics and rubbers, and has the characteristics of oil resistance, wear resistance, low temperature resistance, aging resistance and high hardness, which can reduce the wear of the conveyor belt to a certain extent, improve the service life of the conveyor belt and the polyurethane roller, effectively prevent subsequent bad conditions from occurring, and improve the safety performance. At the same time, the double-threads can play a role in centering and preventing the conveyor belt from running off track to a certain extent.

[0041] Preferably, the end widths of the left helical blade and the right helical blade are 30 mm.

[0042] Preferably, the pitches of the left helical blade and the right helical blade are 45 mm.
