High-efficiency self-repairing reciprocating conveyor belt cleaning method

Abstract

The application discloses a high-efficiency self-repairing reciprocating conveying belt cleaning method. The material adhered to the roller shell can damage and roughen the working surface rubber of the conveying belt, and accelerate the wear of the conveying belt. If the adhered material enters the tail redirection roller, the material will be adhered to the surface of the roller, which can cause the whole conveying belt to run unstably and cause the surrounding environment to be polluted during loading and unloading. The application comprises the following steps: when the conveying belt is started, the sweeper is adjusted through the bearing seat bottom adjusting screw and the adjusting spring buffer; after the conveying belt working surface transports the material, the conveying belt working surface rotates in the empty stroke, and when the conveying belt rotates to the left, the sweeper cleaning plate also moves to the left and is in contact with the conveying belt working surface to scrape; when the conveying belt rotates to the right, the conveying belt drives the sweeper cleaning plate to rotate to the right, and the cleaning plate is scraped again; the head of the cleaning plate is at an angle of 45 degrees for scraping, so that the wear of the conveying belt is small, and the conveying belt is not torn. The application is used for reciprocating conveying belt cleaning.

Description

Technical fields: This invention relates to a highly efficient self-repairing reciprocating conveyor belt cleaning method. Background technology: For large coal mining enterprises, power generation enterprises, metal smelting enterprises, and large ports, when loading and unloading coal, crushed ore, non-ferrous metal sand and gravel, etc., and using large bucket wheel excavators for material handling and conveyor belt transportation, the materials often have stickiness during belt operation; such as mud and powdery materials. Some of these materials will adhere to the working surface of the conveyor belt and cannot be removed during unloading. The sticky material then enters the lower idler rollers in the (reverse) empty section, adhering to the idler roller surface. The adverse consequences are increased radial and axial loads on the bearing housings, causing rapid bearing wear. Material adhering to the idler roller housing will damage and roughen the working surface rubber of the conveyor belt, accelerating belt wear. If the sticky material enters the tail deflector roller, it will adhere to the roller surface, with increasing adhesion and resulting in conveyor belt deviation, increased belt wear, and serious consequences. This will cause overall conveyor belt instability and environmental pollution around the loading and unloading area. Summary of the Invention: The purpose of this invention is to solve the above-mentioned problems and provide an efficient method for cleaning self-repairing reciprocating conveyor belts.

[0004] The above objectives are achieved through the following technical solutions: A highly efficient self-repairing reciprocating conveyor belt cleaning method, comprising the following steps: Step 1: When the conveyor belt starts, the friction on the upper layer of the conveyor belt is at its maximum. The empty conveyor belt will have a downward force, which will damage the sweeper. At this time, the sweeper can be adjusted by adjusting the screw and spring buffer at the bottom of the sweeper frame. Step 2: After the conveyor belt working surface transports materials, the conveyor belt working surface rotates during the idle stroke. When it moves to the left, there is sticky material on the surface. At this time, the cleaning plate of the cleaner also moves to the left to contact the working surface of the conveyor belt for scraping. If the scraping is not thorough, it can be adjusted through the right inclined pressure rod of the cleaning plate. The spring sleeve of the right inclined pressure rod of the cleaning plate can be adjusted to tighten the nut. Step 3: When the conveyor belt rotates in the opposite direction to the right, the conveyor belt will drive the sweeper's cleaning plate to rotate to the right. At this time, the cleaning plate will scrape again. If the scraping is not thorough, it can be adjusted through the left inclined pressure rod of the cleaning plate. Adjust the spring sleeve of the left inclined pressure rod of the cleaning plate to tighten the nut. Step 4: The head of the cleaning plate is at a 45-degree angle to scrape. When the conveyor belt vibrates or the conveyor belt joint is open, it will generate large fluctuations when passing through the cleaning plate. These fluctuations can be buffered by the spring in the inclined pressure sleeve, thus reducing wear on the conveyor belt and preventing it from tearing.

The bearing is located inside the bearing housing, and the center of the bearing is fixed to the cleaning plate assembly. Two symmetrically arranged pressure plates are fixed on the central axis of the cleaning plate assembly, and inclined pressure rods are fixed on the two support frames of the fixing frame.

[0006] The efficient self-repairing reciprocating conveyor belt cleaning method described above includes a support rod fixed on each of the left and right sides of the bearing seat, with the support rod passing through the notch of the support frame.

[0007] The efficient self-repairing reciprocating conveyor belt cleaning method includes a cleaning plate assembly comprising a cleaning plate, a fixing clamp, and a central shaft. The cleaning plate and the fixing clamp are fixed by bolts, and the central shaft is threaded through the fixing clamp.

[0008] The efficient self-repairing reciprocating conveyor belt cleaning method described above includes an inclined pressure bar comprising a sleeve and a spring. The spring is located inside the sleeve, with its upper end fixed to the bottom pressure bar and its lower end fixed to the front pressure bar. The bottom pressure bar and the front pressure bar are respectively slidably engaged with the sleeve, and a nut is threaded onto the bottom pressure bar.

[0009] The efficient self-repairing reciprocating conveyor belt cleaning method described above uses a cleaning plate that is formed by two cleaning plates fastened together, with the ends of the cleaning plates arranged at a 45-degree angle.

[0010] The efficient self-repairing reciprocating conveyor belt cleaning method described herein involves two pressure plates arranged symmetrically at a 45° angle to the horizontal plane.

[0011] Beneficial effects: 1. In this invention, when the conveyor belt starts, the friction on the upper layer of the conveyor belt is at its maximum. During the idle stroke, the conveyor belt will experience a downward force, which can damage the cleaner. The cleaner can be cushioned by the screw spring at the bottom of the cleaner frame. After the conveyor belt has transported material, when the working surface rotates idle (to the left), it will have sticky material on its surface. At this time, the cleaner's cleaning plate will also move to the left to contact the working surface of the conveyor belt and scrape it. If the scraping is incomplete, it can be adjusted by adjusting the right oblique pressure rod of the cleaning plate, which can be adjusted by adjusting the spring sleeve tightening nut of the right oblique pressure rod. When the conveyor belt rotates in the opposite direction (to the right), it will drive the cleaner's cleaning plate to rotate to the right, at which point the cleaning plate will scrape again. If the scraping is incomplete, it can be adjusted by adjusting the left oblique pressure rod of the cleaning plate, which can be adjusted by adjusting the spring sleeve tightening nut of the left oblique pressure rod. 2. The cleaning plate of this invention scrapes at a 45-degree angle. When the conveyor belt vibrates or a conveyor belt joint is open, large fluctuations are generated when the belt passes through the cleaning plate. These fluctuations are buffered by the spring in the inclined pressure sleeve, thus minimizing wear on the conveyor belt and preventing it from tearing. The cleaning plate is made of polyurethane rubber, which is wear-resistant, highly elastic, and has a certain degree of hardness.

[0016] Support rods 12 are fixed on the left and right sides of the bearing housing, and the support rods pass through the notch 13 of the support frame.

[0017] The inclined pressure rod includes a sleeve 11 and a spring 2. The spring is located inside the sleeve, with its upper end fixed to the bottom pressure rod 1 and its lower end fixed to the front pressure rod 3. The bottom pressure rod and the front pressure rod are respectively slidably engaged with the sleeve, and a nut is threaded onto the bottom pressure rod.

[0018] Reference Figure 3 The cleaning plate assembly includes a cleaning plate 8, a fixing clamp 18, and a central shaft 6. The cleaning plate and the fixing clamp are fixed by bolts. The cleaning plate is made of polyurethane rubber. The central shaft is threaded through the fixing clamp.

[0019] The cleaning plate is formed by two cleaning plates being fastened together, and the ends of the cleaning plates are arranged at a 45-degree angle.

[0020] When conveyor belt 5 starts, the friction on the upper layer of the conveyor belt is at its maximum. The idle conveyor belt will experience a downward force, which will damage the cleaner. The cleaner can be cushioned by the screw spring at the bottom of the cleaner frame. After the conveyor belt has transported material, when the working surface rotates idle (to the left), there is sticky material on the surface. At this time, the cleaner's cleaning plate also moves to the left to contact the working surface of the conveyor belt and scrape it. If the scraping is not thorough, it can be adjusted by adjusting the right inclined pressure rod of the cleaning plate, and the spring sleeve tightening nut of the right inclined pressure rod can be adjusted. When the conveyor belt rotates in the opposite direction (to the right), the conveyor belt will drive the cleaner's cleaning plate to rotate to the right. At this time, the cleaning plate will scrape again. If the scraping is not thorough, it can be adjusted by adjusting the left inclined pressure rod of the cleaning plate, and the spring sleeve tightening nut of the left inclined pressure rod can be adjusted. The cleaning plate head scrapes at a 45-degree angle. When the conveyor belt vibrates or a conveyor belt joint is open, the large fluctuations generated when passing through the cleaning plate are buffered by the spring in the inclined pressure sleeve, thus minimizing wear on the conveyor belt and preventing it from tearing. The cleaning plate is made of polyurethane rubber, which is wear-resistant, highly elastic, and has a certain degree of hardness.

[0021] This invention relates to a high-efficiency self-repairing reciprocating conveyor belt cleaner. The cleaning plate's forward and reverse movement coordinates with the conveyor belt's operating conditions. Adjustment is achieved through left and right inclined pressure rods, spring sleeves, and tightening nuts, resulting in better contact between the scraper and the conveyor belt's working surface, and more effectively cleaning any adhering materials. A bottom screw spring at the bottom of the cleaner cushions the downward slippage of the conveyor belt during startup, protecting the cleaner from damage. The scraper is made of polyurethane rubber, a material characterized by low-temperature resistance, high wear resistance, a high coefficient of friction (generally above 0.5), high strength and elasticity within the Shore A60 to Shore A80 hardness range, good cushioning and shock absorption, good oil and chemical resistance, and a long service life.
