Description

Technical Field

[0001] This invention relates to the field of belt cleaning, and more specifically to a centralized intelligent spray washing device and spray washing method. 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] Existing belt cleaning devices are often located behind the redirecting rollers to clean the belt surface after the belt turns. However, during the belt's turning and movement to the cleaning device, not all material is removed from the belt surface, and not all material enters the transfer point chute. This causes material to spill along the belt line under the frame behind the redirecting rollers, requiring the use of a material recovery device to manage the material under the belt frame. This significantly wastes management and material costs, increases the burden of maintenance, and occupies on-site space, making maintenance inconvenient.

[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 technical problem of residual material on the belt surface spilling along the line under the frame behind the redirecting drum in existing technologies, this invention provides a centralized intelligent spray washing device. The centralized intelligent spray washing device includes: a separation structure for cutting and separating residual material on the belt surface attached to the redirecting drum; a spray washing structure for spraying and softening the residual material on the belt surface attached to the redirecting drum; a mud scraping structure for scraping mud from the residual material on the belt surface attached to the redirecting drum; and a water removal structure for removing water from the residual material on the belt surface attached to the redirecting drum.

[0006] The intelligent spray washing device of this invention includes a separation structure, a spray washing structure, a sludge scraping structure, and a water removal structure. The separation structure contacts the belt surface to initially separate and remove residual material. The spray washing structure softens and wets any remaining material, thus cleaning the belt to some extent. The sludge scraping structure removes the wet material, ensuring effective cleaning; the water also acts as a lubricant, preventing damage to the belt. The water removal structure further cleans the remaining moisture and material, enhancing the cleaning effect and ensuring thorough removal and drying of the belt surface. With the above-described configuration, the centralized intelligent spray washing device of this invention can sequentially perform "cutting and separation" – "spray washing and softening" – "scraping off mud" – "draining and wiping clean" – "material storage" on the belt surface of the redirecting drum. The entire cleaning process is completed before the belt leaves the redirecting drum, ensuring that all materials enter the loading point, achieving particle storage, preventing a series of cleaning problems caused by material carried back on the belt, and addressing the issue at its source, avoiding excessive investment of manpower, material resources, and financial resources.

[0007] Furthermore, the separation structure includes a blade holder and a scraper mounted on the blade holder; the spraying structure includes a pipe opened on the blade holder and a nozzle mounted on the blade holder and communicating with the pipe. Through the above arrangement, the spraying structure is placed on the separation structure, integrating the functions of cutting / separation and spraying / softening. This enables rapid assembly of the separation and spraying structures, reduces the space occupied by the centralized intelligent spraying device, and allows the entire centralized intelligent spraying device to be installed at the redirecting roller, cleaning the belt before it leaves the redirecting roller. Simultaneously, placing the spraying structure on the separation structure extends the distance between the spraying structure and the scraping structure, facilitating thorough softening of residual material on the belt surface, further enhancing the cleaning effect, and preventing cleaning from starting before the material is properly moistened.

[0008] Furthermore, a connector is provided at one end of the pipe, and the connector is connected to a water supply device; the water supply device includes a filter, and an electric switch and a manual switch arranged in parallel. Through the above arrangement, the parallel arrangement of the electric switch and the manual switch ensures normal water supply to the nozzles, facilitating belt cleaning.

[0009] Furthermore, it also includes a wheel-type sensor suitable for contacting the belt; the electric switch is linked to the wheel-type sensor, and the electric switch is configured to activate after the wheel-type sensor detects belt movement. Through the above configuration, the wheel-type sensor contacts the bottom surface of the belt and is interlocked with it. This is more reliable than sensors that are embedded in the steel frame or scraper of the cleaning product for vibration and pressure sensing. It avoids sensor damage caused by excessive wear and tear on the cleaner scraper due to long-term belt operation, effectively ensuring the stability and durability of the intelligent control of the centralized intelligent spray washing device; the linkage between the wheel-type sensor and the electric switch ensures that cleaning begins as soon as the belt starts moving.

[0010] Furthermore, the separation structure also includes a mounting bracket detachably connected to the cutter holder; a slide rail is fixed on the mounting bracket, and a groove matching the slide rail is formed on the cutter holder; the slide rail is connected to a mounting structure, which includes a mounting base, a connecting base rotatably connected to the mounting base and connected to the mounting bracket, a limiting post connected to the mounting base and slidingly connected to the connecting base, and a buffer spring sleeved on the outer circumference of the limiting post; one end of the buffer spring abuts against the connecting base. Through the above arrangement, the buffer spring allows the scraper to form flexible contact with the belt, effectively removing sticky material from the separation belt surface while avoiding damage to the belt.

[0011] Furthermore, the sludge scraping structure includes a cleaning seat and a first scraper and a second scraper mounted on the cleaning seat; the first scraper and the second scraper are arranged alternately along the length of the cleaning seat and side by side along the direction of belt movement. Through this arrangement, the alternating arrangement of the first and second scrapers forms a two-stage sludge scraping process, achieving two-stage interception of surface material and enhancing the removal effect of coal sludge.

[0012] Furthermore, a guide rail is installed on the cleaning seat; floating seats matching the guide rail are provided at the bottom of the first and second scrapers, and sliding grooves matching the guide rail are formed on the floating seats; an elastic pre-tightening seat is provided on the cleaning seat. Through the above configuration, the first scraper, the second scraper, and the cleaning seat form a floating connection, which can significantly improve the adaptive cleaning ability of the first and second scrapers on the belt surface, and reduce hard wear on the belt surface while ensuring the sludge scraping effect.

[0013] Furthermore, the dewatering structure includes a dewatering base and detachable T-shaped scrapers mounted on the dewatering base, with multiple T-shaped scrapers arranged side by side. Through this arrangement, the areas where the T-shaped scrapers connect form a hollow space, which not only ensures flexible support for the belt but also facilitates smooth material flow, preventing material accumulation and adhesion to the scrapers, thus avoiding secondary adhesion of material to the belt and ensuring effective belt cleaning.

[0014] Furthermore, it also includes an integrated plate suitable for installation on a belt conveyor, on which the separation structure, the sludge scraping structure, and the water removal structure are detachably mounted. Through the above-described configuration, the arrangement of the integrated plate allows for convenient installation of the separation structure, the sludge scraping structure, and the water removal structure on the belt conveyor.

[0015] To improve or solve the technical problem of residual material on the belt surface spilling along the line under the frame behind the redirecting drum in existing technologies, this invention provides a centralized intelligent spray washing method. The centralized intelligent spray washing method includes: using a separation structure to cut and separate residual material on the belt surface adhering to the redirecting drum; using a spray washing structure to spray and soften the residual material on the belt surface adhering to the redirecting drum; using a sludge scraping structure to scrape sludge from the residual material on the belt surface adhering to the redirecting drum; and using a water removal structure to remove water from the residual material on the belt surface adhering to the redirecting drum. With the above setup, the centralized intelligent spray washing method of this invention can sequentially "cut off and separate" – "spray wash and soften" – "scrape off mud" – "drain and wipe clean" – "material enters the silo" on the belt surface of the redirecting drum. The entire cleaning process is completed before the belt leaves the redirecting drum, ensuring that all materials enter the loading point, achieving particle storage, preventing a series of cleaning problems caused by material carried back on the belt, and addressing the issue at its source, avoiding excessive investment of manpower, material resources and financial resources.

[0016] In summary, compared with the prior art, the present invention has the following beneficial effects: (1) It can sequentially cut off and separate, spray and soften, scrape mud and wipe clean the residual material on the belt surface of the deflector roller. The entire cleaning process is completed before the belt leaves the deflector roller, which can ensure that all materials enter the loading point, realize the return of the particles, prevent the belt from carrying material back and causing a series of cleaning problems, and treat the problem from the source, avoiding excessive investment of manpower, material resources and financial resources. (2) By setting up an integrated plate, the spraying structure is arranged on the separation structure, which can optimize the space of the turning drum, so that the entire centralized intelligent spraying device can be installed at the turning drum and the belt can be cleaned before the belt leaves the turning drum; at the same time, arranging the spraying structure on the separation structure can extend the distance between the spraying structure and the mud scraping structure, which facilitates the full lubrication of the residual material on the belt surface and further enhances the cleaning effect of the belt surface.

[0032] See also Figures 2 to 5In one or more embodiments, the spray washing structure 2 is arranged on the separation structure 1. The spray washing structure 2 includes a pipe 21 opened on the cutter holder 11 and a nozzle 22 installed on the cutter holder 11 and communicating with the pipe 21.

It has reserved wiring terminals for four electric valves with different voltages to meet the convenient application of different voltages on site and to take into account the replacement of electric valves with different voltages in the future, so as to ensure the normal water supply of the sprayer for belt cleaning.

[0033] See also Figures 2 to 5 The electric switch 26 is linked to a wheel sensor 28. The wheel sensor 28 is a DC 12V heavy-duty wheel sensor, fixed to the idler roller frame using an M10 manganese steel chain or rotating bracket. Its contact angle with the belt is adjustable, ensuring stable rotation during long-term belt operation and normal, uninterrupted signal transmission. This independent sensor interlocked with the belt is more reliable than vibration, pressure sensing, or embedded position sensors within the steel frame or scraper of the cleaning product. It avoids sensor damage and signal loss caused by excessive wear and tear on the scraper due to long-term belt operation, effectively guaranteeing the stability and durability of intelligent control. Furthermore, the electric switch 26 is electrically connected to an electrical cabinet via wires, and the electrical cabinet is electrically connected to the wheel sensor 28 via wires. When the belt is running, the electrical cabinet receives the start signal from the wheel sensor 28 and sends a command to open the water supply actuator, allowing clean water to enter the nozzle 22 to spray and soften the material on the belt surface of the redirecting roller.

[0034] See also Figures 2 to 5In one or more embodiments, a mounting groove 113 for accommodating a nozzle 22 is provided on the cutter holder 11 to prevent the nozzle 22 from contacting the belt. The mounting groove 113 is located near the inner wall of the cutter holder 11. Further, a through hole connecting the pipe 21 and the mounting groove 113 is provided on the cutter holder 11, and a tee is provided at the through hole. Two ends of the tee are arranged inside the pipe 21 and are mated with the pipe 21; the third end is mated with the through hole and extends through the through hole into the mounting groove 113. The nozzle 22 is detachably connected to the third end for maintenance and replacement. One tee is arranged at each mounting groove 113, and one nozzle 22 is mounted on the corresponding tee. For example, seven mounting grooves 113 are spaced apart along the length of the cutter holder 11, and one mounting groove 113 is located below a corresponding cutter groove 111. Furthermore, nozzle 22 is a mist cannon nozzle 22, which atomizes clean water into a mist and sprays it onto the conveyor belt to wet the material on the belt surface. Compared to the high-pressure nozzle 22, the mist cannon nozzle 22 can reduce the dust generated during the material cleaning process.

In one or more embodiments, the sludge scraping structure 3 includes a cleaning seat 31 and a first scraper 32 and a second scraper 33 mounted on the cleaning seat 31. The cleaning seat 31 is generally rectangular. A guide rail 34 is mounted on the cleaning seat 31, extending along the length of the cleaning seat 31 and fixed to it by bolts. Specifically, two guide rails 34 are provided, mirror-symmetrically positioned on opposite sides of the cleaning seat 31. Further, limit blocks 35 are provided at both ends of the guide rails 34, with the first scraper 32 and the second scraper 33 arranged between the limit blocks 35. Specifically, bolts are provided on the limit blocks 35, abutting against the cleaning seat 31, thereby fixing the limit blocks 35 to the guide rails 34. Furthermore, the first scraper 32 and the second scraper 33 are staggered along the length of the cleaning seat 31, that is, a second scraper 33 is arranged between two adjacent first scrapers 32, and a first scraper 32 is arranged between two adjacent second scrapers 33. The first scrapers 32 and the second scrapers 33 are arranged side by side along the direction of belt movement, that is, multiple first scrapers 32 form a first row along the direction of belt movement, and multiple second scrapers 33 form a second row along the direction of belt movement. The first row is located in front of the second row along the direction of belt movement, thereby performing secondary scraping of the wetted material on the belt. In one or more embodiments, the first scraper 32 and the second scraper 33 are arranged abutting each other along the length of the guide rail 34, and are limited by the limiting blocks 35 at both ends (e.g., Figure 8 (As shown). In another embodiment, the first scraper 32 and the second scraper 33 are arranged at intervals along the direction of the guide rail 34, and a spacer is provided between adjacent first scrapers 32 and second scrapers 33, which makes it easier to position the first scrapers 32 and second scrapers 33 (e.g.). Figure 7 (As shown). Furthermore, the first scraper 32 and the second scraper 33 are provided with embedding grooves, and blades are disposed in the embedding grooves. Specifically, multiple blades are arranged along the length of the embedding groove. For example, three blades are arranged along the length of the embedding groove, which makes it easier to replace the blades.

[0036] like Figure 2 , Figure 7 and Figure 8As shown, floating seats 36 that match the guide rail 34 are provided at the bottom of the first scraper 32 and the second scraper 33, and sliding grooves that match the guide rail 34 are formed on the floating seats 36. Specifically, the size of the sliding grooves is slightly larger than the size of the guide rail 34, so that the floating seats 36 can swing to a certain extent in the direction of belt movement, thereby forming a flexible connection between the first scraper 32 and the second scraper 33 and the belt, ensuring the belt cleaning effect while avoiding belt damage. Furthermore, elastic pre-tensioning seats 37 are provided at both ends of the cleaning seat 31, and the elastic pre-tensioning seats 37 are fixedly connected to the integrated plate 5 by bolts. Specifically, the elastic pre-tensioning seat 37 includes a fixed cylinder 371 sleeved on the cleaning seat 31, a threaded shaft 372 installed on the fixed cylinder 371, a fixed seat 373 fixedly connected to the integrated plate 5, and a pre-tensioning spring 374 sleeved on the threaded shaft 372. A fixing bolt is provided at the end of the threaded shaft 372 away from the fixed cylinder 371, and the two ends of the preload spring 374 abut against the fixing bolt and the fixed seat 373 respectively.

[0037] Figure 9 This is a schematic diagram of an embodiment of the water removal structure 4 in the centralized intelligent spray washing device of the present invention. (See diagram below.) Figure 2 and Figure 9 As shown, the dewatering structure 4 includes a dewatering base 41 and a detachable T-shaped scraper 42 mounted on the dewatering base 41. Specifically, the dewatering base 41 is generally cylindrical. Elastic pre-tightening seats are also provided at both ends of the dewatering base 41. These elastic pre-tightening seats have the same structure as the elastic pre-tightening seat 37 of the sludge scraping structure 3, and will not be described again here. Specifically, a connecting seat 43 is provided between the T-shaped scraper 42 and the dewatering base 41. The T-shaped scraper 42 and the connecting seat 43 are fixedly connected by bolts, and the connecting seat 43 and the dewatering base 41 are also fixedly connected by bolts. Furthermore, multiple T-shaped scrapers 42 are arranged side-by-side and abutting each other to scrape water off the belt. Hollow grooves are formed between adjacent T-shaped scrapers 42, which not only ensures flexible support for the belt but also facilitates smooth material flow, preventing material accumulation and adhesion to the scraper, thus preventing secondary adhesion of material to the belt and ensuring effective belt cleaning.

[0038] The centralized intelligent spray washing device of the present invention has the following beneficial effects: 1. Thoroughly remove materials from the source of the belt to the unloading point, eliminate secondary spillage of materials after the belt leaves the deflector roller, reduce investment in cleaning devices and sewage dredging equipment, improve the production site environment, ensure that material particles are stored properly, eliminate product loss, and increase output. 2. Optimize the space at the redirecting roller to facilitate the installation and application of belt conveyor accessories; 3. Reduce investment in cleaning equipment and production materials to lower operating and maintenance costs; 4. Reduce wear on the belt to the idler roller and belt conveyor, extend the product life of the belt conveyor, reduce the labor intensity of workers, and improve personal safety; 5. Eliminate material accumulation, prevent material from running along the conveyor belt, avoid friction causing high temperature and fire, and improve equipment safety; 6. Eliminate material adhering to the idler rollers of the redirecting roller conveyor to prevent belt misalignment.

[0039] To improve or solve the technical problem of residual material on the belt surface spilling along the line behind the redirecting drum in existing technologies, this invention provides a centralized intelligent spray washing method. This centralized intelligent spray washing method includes: using a separation structure 1 to cut and separate residual material on the belt surface adhering to the redirecting drum; using a spray washing structure 2 to spray and soften the residual material on the belt surface adhering to the redirecting drum; using a mud scraping structure 3 to scrape mud from the residual material on the belt surface adhering to the redirecting drum; and using a water removal structure 4 to remove water from the residual material on the belt surface adhering to the redirecting drum.

[0040] In one or more embodiments, the centralized intelligent spray washing method of the present invention includes: Step S1 involves using the separation structure 1 to cut and separate the residual material on the belt surface attached to the redirecting roller. The separation structure 1 is located at the lower right of the redirecting roller. The separation structure 1 includes a cutter holder 11 and a scraper 12. The scraper 12 is detachably connected to the cutter holder 11 and can be replaced if damaged. A scraper strip 123 is detachably mounted on the scraper 12 and can be replaced if damaged.

[0041] Step S2 involves using a spray washing structure 2 to soften and wash the residual material on the belt surface attached to the redirecting roller. The spray washing structure 2 is located on the separation structure 1. The spray washing structure 2 includes a scraper mounted on a cutter holder 11 and a nozzle 22 mounted on the cutter holder 11. The nozzle 22 is connected to a water supply unit, which includes a filter 25 and a parallel-connected electric switch 26 and a manual switch 27. The electric switch 26 is linked to a wheel sensor 28. When the belt is running, the electrical cabinet receives a start signal from the wheel sensor 28 and sends a command to open the water supply actuator, allowing clean water to enter the nozzle 22 and soften the material on the belt surface of the redirecting roller.

[0042] Step S3 involves using a scraping structure 3 to scrape away residual material from the belt surface adhering to the redirecting roller. The scraping structure 3 is located behind the separation structure 1 along the belt's movement direction. The scraping structure 3 includes a cleaning seat 31 and a first scraper 32 and a second scraper 33 mounted on the cleaning seat 31. The first scraper 32 and the second scraper 33 form a two-stage scraping structure 3, performing two-stage scraping of the material on the belt to ensure effective removal.

[0043] Step S4 involves using a dewatering structure 4 to remove residual material from the belt surface adhering to the redirecting roller. The dewatering structure 4 is located behind the scraping structure 3 along the belt's movement direction. The dewatering structure 4 includes a dewatering base 41 and T-shaped scrapers 42. A perforated groove is formed between adjacent T-shaped scrapers 42, which not only ensures flexible support for the belt but also facilitates smooth material flow, preventing material accumulation and adhesion to the scrapers, thus avoiding secondary adhesion of material to the belt and ensuring effective belt cleaning.
