Description

Technical Field

[0001] This utility model relates to the field of belt cleaning, specifically to a return belt intelligent spray cleaner. Background Technology

[0002] In mining, thermal power, coal chemical, and port industries, belt conveyors transporting bulk materials often experience spillage during the return journey. Material adhering to the belt surface enters the idler rollers and the entire belt conveyor frame, spilling along the line below the frame. This not only pollutes the site environment and poses significant risks due to the difficulty and danger of manual cleaning, but also creates potential health and safety hazards and the possibility of belt fires. Long-term operation can lead to premature detachment of the belt rubber layer and roller coating, premature damage to the idler roller shells, and belt misalignment. This results in frequent maintenance, a large amount of repair work, and excessively high annual operating and production costs.

[0003] Chinese utility model patent CN223200972U discloses a complete intelligent belt cleaning device, including a belt conveyor with belt guide pulleys, a belt cleaner, and wheel sensors fixedly installed on it. The belt cleaner removes residual material from the belt using a scraper. However, in practical use, it has been found that many sites are unable to install and use this device due to space constraints. Some cleaning devices also require secondary input of other cleaning equipment after removing material from the belt to complete the waste cement slurry treatment. Cleaning the material solely with a scraper is ineffective and inconvenient for subsequent cleaning.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the problem of poor cleaning effect in existing technologies that rely solely on scrapers to clean materials on belts, this utility model provides a return belt intelligent spray cleaner. The return belt intelligent spray cleaner includes: a cutter holder with a pipe on it and a nozzle connected to the pipe mounted on it; and a scraper detachably mounted on the cutter holder.

[0006] This utility model discloses a smart spray cleaner for return belts, comprising a blade holder and a scraper. The scraper is detachably mounted on the blade holder and can scrape off residual material on the belt surface, preventing material spillage. A pipe is provided on the blade holder for conveying clean water; a nozzle is installed on the blade holder, connected to the pipe, which sprays the clean water from the pipe onto the belt after it has been scraped off by the scraper, cleaning and wetting any remaining material on the belt, facilitating subsequent cleaning by a cleaner. Through the above configuration, this utility model of a smart spray cleaner for return belts can initially remove and separate material from the belt surface, then clean and wet any remaining material, enhancing the cleaning effect of the return belt.

[0007] Furthermore, a mounting groove is provided on the blade holder, and the nozzle is arranged in the mounting groove; a connector is provided at one end of the pipe, and a plug is provided at the other end of the pipe. Through the above arrangement, the mounting groove can accommodate the nozzle, thereby preventing the nozzle from contacting the belt and preventing damage to the nozzle.

[0008] Furthermore, a scraper strip is embedded in the scraper. With this configuration, the scraper strip can be replaced after it wears out, thereby reducing the scraper's operating cost.

[0009] Furthermore, it also includes a mounting bracket that is detachably connected to the tool holder; a slide rail is fixed on the mounting bracket, and a groove matching the slide rail is formed on the tool holder. Through the above configuration, the tool holder can be detachably mounted on the mounting bracket, allowing for convenient installation and removal. The arrangement of the slide rail and groove ensures the connection stability between the tool holder and the mounting bracket, preventing the tool holder from shaking.

[0010] Furthermore, limit blocks are provided at both ends of the slide rail, and abutment posts that abut against the tool holder are detachably arranged on the limit blocks. Through the above-described arrangement, the abutment posts prevent the tool holder from sliding off the mounting bracket.

[0011] Furthermore, the system also includes an installation structure comprising a mounting base, a connecting seat that rotates relative to the mounting base and is connected to the mounting frame, a limiting post that is connected to the mounting base and forms a sliding fit with the connecting seat, and a buffer spring sleeved on the outer circumference of the limiting post; one end of the buffer spring abuts against the connecting seat. With the above configuration, the mounting base is suitable for installation on a belt conveyor; when the scraper cuts material off the belt, the scraper, cutter holder, and connecting seat rotate under the pressure of the belt and the material, and the connecting seat presses against the buffer spring, providing cushioning for the scraper, ensuring flexible contact between the scraper and the belt, and preventing belt damage.

[0012] Furthermore, a telescopic rod that rotates synchronously with the connecting seat is fixed inside the mounting bracket, and a nylon bushing is provided between the telescopic rod and the mounting bracket. Through this arrangement, the nylon bushing reduces rotational wear between the telescopic rod and the mounting bracket, extending the service life of both.

[0013] Furthermore, a buffer rubber ring is fitted onto the end of the limiting post near the mounting base. Through this arrangement, the sliding stroke of the connecting base can be limited on the limiting post where the buffer rubber ring is located.

[0014] Furthermore, a washer and a limiting nut are provided at the end of the limiting post away from the mounting base, and the two ends of the buffer spring abut against the connecting base and the washer, respectively.

[0015] Furthermore, a sleeve is fitted around the outer circumference of the buffer spring. This sleeve protects the buffer spring, preventing material from adhering to it and affecting its normal operation.

[0016] In summary, compared with the prior art, this utility model has the following beneficial effects: (1) The material on the belt surface is initially removed and separated by scraper, and the remaining material is cleaned and moistened by nozzle. This can enhance the cleaning effect of the return belt. The material is removed from the belt surface at the unloading drum, avoiding secondary spillage of the material, reducing the layout of cleaning devices and sewage dredging equipment, reducing operating and maintenance costs, improving the space and environment of the production site, reducing the wear of the belt on the diversion drum and idler housing, and extending the service life of the belt conveyor. (2) The arrangement of the nozzles can eliminate material accumulation, prevent material from affecting the belt operation, avoid high temperature fire caused by friction between the subsequent cleaner and the belt, and improve equipment safety; (3) The arrangement of the sprayers can eliminate the material adhering to the redirecting rollers and idlers, and prevent the belt from running off track; at the same time, it ensures that the material particles are returned to the warehouse, eliminates product loss, and increases output. (4) The arrangement of the sprayers can ensure the clean operation of the belt, reduce dust generation, and reduce the investment in dust removal equipment. Attached Figure Description
