Description

Technical Field

[0001] This utility model relates to the field of belt conveyors, and in particular to a cleaning device for belt operation. Background Technology

[0002] Belt conveyors, as a highly efficient and continuous material transport equipment, are widely used in many industrial fields such as mining, metallurgy, chemical industry, ports, power, building materials, and food due to their significant advantages such as strong conveying capacity, simple structure, convenient maintenance, and low operating costs. They are responsible for conveying a wide variety of materials, including bulk materials such as coal, ore, and sand, as well as packaged goods such as grain, fertilizer, and parcels.

[0003] During the operation of belt conveyors, especially when conveying materials with high moisture content, strong viscosity, or containing fine particles, such as wet coal, clay, mineral powder, and cement, the problem of material adhesion and residue will inevitably occur.

[0004] Due to material characteristics or spillage, a small amount of material may stick to the front of the belt and fail to be completely unloaded; some fine powder or particles, especially mud-water mixtures, may be carried to the return section as the belt rotates. During long-term operation, they may also have strong adhesion to the back of the belt, which can easily lead to equipment safety accidents such as slippage, deviation, or even belt tearing. Utility Model Content

[0005] In order to improve the cleaning effect of the cleaning device on the belt, this utility model provides a cleaning device for belt operation.

[0006] This utility model provides a cleaning device for belt conveyors, which adopts the following technical solution:

[0007] A cleaning device for belt-driven operation includes a frame, a main drive roller, a secondary drive roller, a belt, and a cleaning mechanism. The main drive roller and the secondary drive roller are rotatably mounted on the frame. The belt is sleeved on the main drive roller and the secondary drive roller, and the main drive roller drives the belt to rotate.

[0008] The cleaning mechanism includes a tensioning roller barrel, which comprises a fixed frame, a first rotating shaft, a first auxiliary wheel, and a scraper roller. The fixed frame is fixedly mounted on the machine frame and has a sliding groove. The two ends of the first rotating shaft are slidably mounted in the sliding groove of the fixed frame. The first auxiliary wheel is rotatably mounted on both ends of the first rotating shaft. A plurality of scraper rollers are fixedly mounted on the first auxiliary wheel along its circumference. A first counterweight is connected to the first rotating shaft. The belt is sleeved on the scraper roller, and the tensioning roller barrel pulls the belt downward under the gravity of the first counterweight.

[0009] Preferably, the tensioning roller further includes fins and a guide plate, with a plurality of fins evenly distributed on the first auxiliary wheel along the circumference of the first auxiliary wheel, and the upper end of the guide plate rotatably sleeved on the first rotating shaft.

[0010] Preferably, a collection trough is installed below the tensioning roller.

[0011] Preferably, the cleaning mechanism further includes a steering roller barrel, with two steering roller barrels disposed on both sides of the tensioning roller barrel and the steering roller barrel located above the tensioning roller barrel; the steering roller barrel includes a second rotating shaft, a second auxiliary wheel, and connecting rods, the second rotating shaft being fixedly mounted on the frame, and a plurality of connecting rods being fixedly mounted on the second auxiliary wheel along the circumference of the second auxiliary wheel.

[0012] Preferably, the cleaning mechanism further includes a first scraper and a second counterweight. The first end of the first scraper is rotatably mounted on the frame, the second counterweight is connected to the first end of the first scraper, and the second end of the first scraper is arc-shaped. Under the gravity of the second counterweight, the first scraper abuts against the belt.

[0013] Preferably, the cleaning mechanism further includes a limiting wheel, which is rotatably mounted on the first scraper, located below the main drive roller, and in rolling contact with the belt.

[0014] Preferably, the cleaning mechanism further includes a second scraper, which is fixedly mounted on the frame and abuts against the upper surface of the belt near the auxiliary drive roller.

[0015] Preferably, the cleaning mechanism further includes a brush roller, which is rotatably mounted on the frame and located inside the belt between the two steering roller drums. The brush roller abuts against the belt, and a driver is installed inside the brush roller to drive the brush roller to rotate. The rotation direction of the brush roller is opposite to the running direction of the belt.

[0016] Preferably, a guide trough is installed on the frame below the main drive roller.

[0017] In summary, this utility model has at least one of the following beneficial technical effects:

[0018] 1. The scraper roller can always press the working surface of the belt with a constant, gentle and continuous force, avoiding the problems of excessive pressure aggravating wear or insufficient pressure leading to ineffective cleaning caused by traditional fixed scrapers; the tensioning roller barrel not only performs the cleaning function, but also tensions the belt, making it a dual-purpose machine and simplifying the overall structure.

[0019] 2. The two steering rollers force the belt to form a larger concave arc at the tension roller, greatly increasing the contact area and contact time between the belt and the scraper roller on the lower tension roller. This makes cleaning more thorough, especially effective for stubborn deposits. The contact between the multiple connecting rods on the steering rollers and the belt is dynamic and gradual, avoiding sudden belt bending, reducing stress concentration, and helping to protect the belt.

[0020] 3. Gravity self-adaptation is achieved through the second counterweight, ensuring that the first scraper always contacts the non-working surface of the belt with optimal pressure, adapting to belt deviation and jumping, effectively cleaning and avoiding excessive wear.

[0021] 4. The second scraper can further scrape and clean the non-working surface of the belt that is about to enter the auxiliary drive roller, and clean the finer impurities on the non-working surface of the belt, thus further improving the cleaning effect. Attached Figure Description

[0034] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0035] This utility model discloses a cleaning device for belt conveyors. (Refer to...) Figures 1 to 4A cleaning device for belt-driven applications mainly includes a frame, a main drive roller 110, a secondary drive roller 120, a belt 130, and a cleaning mechanism 200. The frame serves as the basic support for the device and is adjusted according to the installation or usage environment; therefore, the frame is not labeled. Both the main drive roller 110 and the secondary drive roller 120 are rotatably mounted on the frame. The belt 130 is fitted onto the main drive roller 110 and the secondary drive roller 120, with the main drive roller 110 driving the belt 130 to rotate. The cleaning mechanism 200 includes a tension roller barrel 210, which comprises a fixed frame 211, a first rotating shaft 212, a first auxiliary wheel 213, and a scraper roller 214. The fixed frame 211 is fixedly mounted on the frame and has sliding grooves 215. The first rotating shaft 212 has two sliding grooves 215. The first auxiliary wheel 213 is rotatably mounted on both ends of the first rotating shaft 212. Multiple scraper rollers 214 are fixedly mounted on the first auxiliary wheel 213 along its circumference. A first counterweight 216 is connected to the first rotating shaft 212 by a connecting rope. The belt 130 is sleeved on the scraper roller 214. The tensioning roller 210 pulls the belt 130 downward under the gravity of the first counterweight 216. A rotational damping adjuster can be installed between the first rotating shaft 212 and the first auxiliary wheel 213. By adjusting the rotational resistance between the first rotating shaft 212 and the first auxiliary wheel 213, a speed difference is generated between the scraper roller 214 and the belt 130, which can better scrape the belt 130.

[0036] Automatic tensioning is achieved through the gravity of the first counterweight 216. Regardless of how the belt 130 stretches or vibrates, the scraper roller 214 always presses the working surface of the belt 130 with a constant, gentle, and continuous force, avoiding the problems of excessive pressure leading to increased wear or insufficient pressure leading to ineffective cleaning caused by traditional fixed scrapers. Multiple scraper rollers 214 are arranged circumferentially. As the belt 130 runs and the tensioning roller drum 210 rotates, these scraper rollers 214 continuously "plow" across the surface of the belt 130, scraping and peeling off the adhered material from multiple angles and continuously. The cleaning effect is far superior to that of a single scraper. Unlike the sliding friction of fixed scrapers, the contact between the scraper roller 214 and the belt 130 in this case is closer to rolling friction, which can significantly reduce wear on the surface of the belt 130 and extend the service life of the belt 130 and the cleaning device itself. The tensioning roller drum 210 performs the cleaning function while also tensioning the belt 130, serving two purposes and simplifying the overall structure of the machine.

[0037] Reference Figure 4In some embodiments, the tensioning roller 210 further includes blades 218 and a guide plate 217. Multiple blades 218 are evenly distributed circumferentially on the first auxiliary roller 213, and the upper end of the guide plate 217 is rotatably mounted on the first rotating shaft 212. The blades 218 can guide the scraped waste material onto the guide plate 217, reducing the possibility of splashing. The rotatable guide plate 217 can accurately guide and collect the scraped material into a predetermined area, preventing the cleaned material from splashing everywhere and causing secondary pollution to the equipment or environment, thus achieving clean collection.

[0038] Reference Figure 1 In some embodiments, a collection trough 140 is installed below the tension roller drum 210. Together with the guide plate 217, this forms a complete "cleaning-collection" closed-loop system. The scraped material is directly guided into the collection trough 140 for centralized processing or recycling, greatly reducing the workload of manual cleaning and improving the automation level and environmental friendliness of the equipment.

[0039] Reference Figure 1 , Figure 5 and Figure 6 In some embodiments, the cleaning mechanism 200 further includes two guide roller drums 220, which are disposed on both sides of the tension roller drum 210 and located above the tension roller drum 210. Each guide roller drum 220 includes a second rotating shaft 221, a second auxiliary wheel 222, and connecting rods 223. The second rotating shaft 221 is fixedly mounted on the frame, and multiple connecting rods 223 are fixedly mounted on the second auxiliary wheel 222 circumferentially. The two guide roller drums 220 force the belt 130 to form a larger concave arc segment at the tension roller drum 210, greatly increasing the contact area and contact time between the belt 130 and the scraper roller 214 on the lower tension roller drum 210. This makes cleaning more thorough, especially effective for stubborn adhesives. The contact between the multiple connecting rods 223 on the guide roller drum 220 and the belt 130 is dynamic and gradual, avoiding sudden bending of the belt 130, reducing stress concentration, and protecting the belt 130.

[0040] Reference Figure 1 and Figure 7In some embodiments, the cleaning mechanism 200 further includes a first scraper 230 and a second counterweight 240. The first end of the first scraper 230 is rotatably mounted on the frame. The second counterweight 240 is connected to the first end of the first scraper 230 via a connecting rope. The second end of the first scraper 230 is arc-shaped. Under the gravity of the second counterweight 240, the first scraper 230 abuts against the belt 130. This device can simultaneously clean the non-working surface of the belt 130 using the tension roller 210 and the working surface using the first scraper 230, effectively preventing roller wear and spillage caused by material sticking to the return belt 130. The second counterweight 240 enables gravity self-adaptation, ensuring that the first scraper 230 always contacts the non-working surface of the belt 130 with optimal pressure, adapting to belt deviation and jumping, effectively cleaning while avoiding excessive wear.

[0041] Reference Figure 7 In some embodiments, the cleaning mechanism 200 further includes a limiting wheel 250, which is rotatably mounted on the first scraper 230. The limiting wheel 250 is located below the main drive roller 110 and is in rolling contact with the belt 130.

[0042] The limiting wheel 250 provides a reliable fulcrum for the first scraper 230, preventing the scraper from swinging or shifting excessively under the action of the belt 130, ensuring the stability and consistency of its cleaning posture, thereby ensuring continuous cleaning effect, and avoiding accidental damage to the belt 130.

[0043] Reference Figure 1 In some embodiments, the cleaning mechanism 200 further includes a second scraper 260, which is fixedly mounted on the frame and abuts against the upper surface of the belt 130 near the auxiliary drive roller 120. The second scraper 260 can further scrape and clean the non-working surface of the belt 130 that is about to enter the auxiliary drive roller, and clean finer impurities on the non-working surface of the belt 130, thereby further improving the cleaning effect.

[0044] Reference Figure 5 In some embodiments, the cleaning mechanism 200 further includes a brush roller 270, which is rotatably mounted on the frame and located within a belt 130 between two steering roller drums 220. The brush roller 270 abuts against the belt 130, and a driver is installed within the brush roller 270 to drive its rotation. The rotation direction of the brush roller 270 is opposite to the running direction of the belt 130. The rotating scrubbing action of the brush roller 270 is very suitable for removing fine powdery residues embedded deep in the texture; the counter-rotation of the brush roller 270 and the belt 130 generates a higher relative speed, which is equivalent to increasing the "scrubbing" force, thereby greatly improving the scrubbing efficiency and cleanliness.

[0045] Reference Figure 1In some embodiments, a guide trough 150 is installed on the frame below the main drive roller 110. The material conveyed from the belt 130 enters the guide trough 150 for continued conveying, preventing the material from falling directly onto the ground or equipment foundation, keeping the site clean, and reducing waste and safety hazards.

[0046] The implementation principle of a cleaning device for belt conveyors according to an embodiment of this utility model is as follows:

[0047] By utilizing the gravity of the counterweights, the scraper roller 214 applies a constant, gentle, and continuous force to press the belt 130, achieving a combination of adaptive tensioning and efficient cleaning. This fundamentally solves the wear or failure problems caused by uneven pressure in traditional scrapers. Furthermore, by adding a steering roller 220 to create a concave arc section with an increased wrap angle, the cleaning contact area and time are significantly increased, thereby greatly improving the cleaning effect on stubborn adhering substances. The entire device also achieves adaptive cleaning of the non-working surface of the belt 130 through multiple counterweight structures, effectively adapting to belt deviation and avoiding excessive wear.

[0048] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
