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

[0002] In the metallurgical industry, the frequent use of wet materials in belt conveyors makes the phenomenon of material carryover on return trips particularly prominent. Given current environmental protection requirements, taking effective measures to reduce material carryover and wastewater runoff during belt conveyor transport is crucial, for example;

[0003] Authorized publication number CN217050401U discloses a belt cleaning device for use on a belt conveyor. Specifically, the device includes a fixed base and a flexible scraper. The fixed base gradually decreases in height from the side closest to the belt conveyor towards the side furthest away from it. The flexible scraper is detachably mounted on the fixed base, with one end extending beyond the fixed base towards the belt conveyor and contacting the belt itself. This belt cleaning device solves the problem of material easily adhering to the belt surface in existing technologies. It also features a simple structure, easy manufacturing, low cost, and excellent practicality.

[0004] However, the existing belt return cleaning device is not convenient to quickly disassemble the scraper after use, which makes it easy for the scraped oil to remain on the surface of the scraper for a long time. This residual oil can affect the scraper's treatment effect and reduce the maintenance and cleaning efficiency of the device.

[0005] Therefore, in order to address the above problems, there is an urgent need for innovative design based on the existing belt return cleaning device. Utility Model Content

[0006] The purpose of this utility model is to provide a belt return cleaning device to solve the problem mentioned in the background art that it is not convenient to quickly disassemble the scraper after use, which causes the scraped oil to remain on the surface of the scraper for a long time, resulting in the residual oil affecting the scraper's treatment effect and reducing the maintenance and cleaning efficiency of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a belt return cleaning device, comprising: a water tank, and a second support frame disposed on the upper side of the water tank, wherein a scraping cleaning plate is installed on the upper side of the second support frame, a water spray pipe is disposed on the rear side of the second support frame, and an air jet pipe is disposed on the front end of the second support frame;

[0008] Also includes:

[0009] A guide block is installed inside the water tank, and a collection box is connected to the upper side of the guide block. A sealing ring is installed on the upper side of the collection box. A water inlet is provided on the right side of the water tank, and a drain valve is provided on the lower side of the water inlet. A screening and interception component is installed on the outer side of the collection box, and a transport component is provided on the lower side of the water tank.

[0010] A limiting block is installed inside the second support frame, and an operating handle is provided on the lower side of the limiting block. A second guide rod is connected to the outer side of the limiting block, and a damper is provided in the middle of the limiting block. A water supply pipe is connected to the rear side of the water spray pipe, and a water pump is connected to the lower side of the water supply pipe. A third support frame is provided on the left side of the water tank, and an operating box is installed in the middle of the third support frame.

[0011] In one possible implementation, the collection box is slidably connected to the guide block, and the sealing ring is engaged with the collection box.

[0012] In one possible scenario, the scraping cleaning plate is engaged with the second support frame, and the limiting blocks are symmetrically arranged about the central axis of the scraping cleaning plate.

[0013] In one possible implementation, the limiting block is engaged with the scraping cleaning plate and slidably connected to the second guide rod.

[0014] In one possible implementation, the transport assembly includes a mounting plate installed on the lower side of the water tank, with casters connected to the lower side of the mounting plate, a first guide rod provided on the outer side of the mounting plate, and an electric telescopic rod installed on the upper side of the mounting plate.

[0015] The mounting plate is slidably connected to the first guide rod, and the first guide rod is positioned on the upper left and right sides of the central axis of the mounting plate.

[0016] In one possible implementation, the screening and interception assembly includes a first support frame installed on the outside of the collection box, and an interception net is provided inside the first support frame. A positioning block is connected to the outside of the first support frame, and a limit rod passes through the middle of the positioning block.

[0017] The positioning block is engaged with the collection box, and the longitudinal section of the positioning block is a "T" shaped structure.

[0018] In one possible implementation, the limiting rod is threadedly connected to both the positioning block and the collection box, and the limiting rod is symmetrically arranged about the central axis of the first support frame.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This belt return cleaning device allows for quick and easy disassembly of the scraper after use, preventing the scraped oil from remaining on the scraper surface for extended periods, thus avoiding any impact on the scraper's processing effect and improving the device's maintenance and cleaning efficiency. Simultaneously, it facilitates the collection of scraped solid impurities during use, making it easy for operators to recover and clean these impurities, further improving the device's efficiency and resulting in better performance. Specifically, as shown below:

[0020] 1. The electric telescopic rod, in conjunction with the first guide rod, pushes the mounting plate to move downward inside the water tank, causing the mounting plate to push the universal wheel connected to its lower side to protrude from the lower surface of the water tank. This makes it easier for the operator to push the device along the universal wheel for transportation, reducing the operator's labor intensity.

[0021] 2. The first support frame is fixed to the outside of the collection box by the positioning block and the limiting rod, so that the first support frame fixes the interception net on the left and right sides of the collection box. At this time, the interception net intercepts the impurities that fall into the collection box, preventing the impurities from being re-accompanied by the cleaning water spray on the belt surface, thereby improving the impurity recovery and cleaning effect of the device.

[0022] 3. By operating the handle in conjunction with the second guide rod, the limiting block is moved outward, which relaxes the limiting block's engagement with the scraping cleaning plate, making it easier for the operator to pull it upward to remove the scraping cleaning plate for disassembly and maintenance, thus improving the maintenance and cleaning efficiency of the device.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a belt return cleaning device, including a water tank 1, a mounting plate 2, a caster wheel 3, a first guide rod 4, an electric telescopic rod 5, a guide block 6, a collection box 7, a first support frame 8, a positioning block 9, a limiting rod 10, a trapping net 11, a sealing ring 12, a water inlet 13, a drain valve 14, a second support frame 15, a scraping cleaning plate 16, a limiting block 17, an operating handle 18, a second guide rod 19, a damper 20, a water pump 21, a water supply pipe 22, a water spray pipe 23, a jet spray pipe 24, a third support frame 25, and an operating box 26.

[0032] Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, before using the device, the electric telescopic rod 5 located on the lower side of the water tank 1 is activated, causing the electric telescopic rod 5 to push the mounting plate 2 connected to its lower side to move downward. At this time, due to the sliding connection structure between the mounting plate 2 and the first guide rod 4, the mounting plate 2 is guided and limited by the first guide rod 4 during the downward sliding process, preventing the mounting plate 2 from shifting position during the downward displacement. At this time, the mounting plate 2 pushes the universal wheel 3 connected to its lower side to protrude from the lower surface of the water tank 1 along the first guide rod 4, making it easy for the operator to push the device to the designated position along the universal wheel 3. When the device moves to the lower side of the belt, the electric telescopic rod 5 on the lower side of the water tank 1 is restarted, causing the electric telescopic rod 5 to drive the mounting plate 2 to move upward along the first guide rod 4 located on its outer side. At this time, the mounting plate 2 drives the universal wheel 3 connected to its lower side to retract into the interior of the water tank 1, thus completing the convenient movement and transportation of the device and reducing the labor intensity of the operator. At this time, the water inlet pipe is connected to the right side of the water inlet 13, so that the liquid inside the water inlet pipe passes through the water inlet located on the right side of the water tank 1. The water enters the interior of the water tank 1 through the inlet 13. At this time, by operating the control box 26 located in the middle of the third support frame 25, the control box 26 sends a valid electrical signal to start the water pump 21 located at the rear of the water tank 1. The water pump 21 then draws and pressurizes the cleaning water poured into the water tank 1, causing the cleaning water to flow through the water pipe 22 connected to the upper side of the water pump 21 into the spray pipe 23. The cleaning water is then sprayed onto the lower surface of the belt through the spray pipe 23, thus initially wetting and cleaning the belt. At this time, the belt moving towards the front is subjected to the first... The scraping and cleaning plate 16 installed on the upper side of the second support frame 15 scrapes away impurities and stains from the belt surface, causing them to fall downwards. At this time, the front end of the air jet pipe 24 connected to the air intake pipe allows the rapidly flowing gas to be sprayed upwards through the air jet pipe 24 to dry the surface of the belt. This prevents the belt from slipping due to the cleaning water after cleaning, thus completing the belt cleaning work, improving the processing effect of the device, and increasing the efficiency of the device.

[0033] Specifically, such as Figure 1 , Figure 4 and Figure 6As shown, during the use of the device, the positioning block 9, which is set along the outer side of the first support frame 8, is installed on the outer side of the collection box 7. Due to the "T"-shaped structure of the positioning block 9, the first support frame 8 is initially positioned on the outer side of the collection box 7. Then, the limiting rod 10, which passes through the middle of the positioning block 9, is rotated. Because of the threaded connection between the limiting rod 10 and the positioning block 9 and the collection box 7, the inwardly rotating limiting rod 10 effectively connects the positioning block 9 and the collection box 7 together. At this point, the first support frame 8 will... The intercepting net 11 is fixed to the outside of the collection box 7 and pushes the collection box 7 inward. Due to the sliding connection structure between the collection box 7 and the guide block 6, the pushed collection box 7 enters the water tank 1 along the guide block 6. At this time, due to the engaging connection structure between the sealing ring 12 and the collection box 7, the collection box 7 carries the sealing ring 12 into the device as it enters the water tank 1. At this time, due to the sealing characteristics of the sealing ring 12, the sealing ring 12 entering the device can effectively seal the connection gap between the upper side of the collection box 7 and the water tank 1. When the blockage is blocked, the scraped dirt and impurities fall into the collection box 7, where the collection box 7 collects these scraped solid impurities. At this time, the interception net 11 fixed on the outside of the collection box 7 blocks and intercepts the falling impurities, preventing them from being transported indiscriminately with the water flow and clogging the drain valve 14, thus improving the cleaning and recycling effect of the device and increasing the efficiency of the device. At the same time, after the device is used, by pulling the operating handle 18 outward, the operating handle 18 causes the limiting block 17 connected to its upper side to move outward. Due to the sliding connection structure between the limiting block 17 and the second guide rod 19, the limiting block 17 is guided and limited by the second guide rod 19 during the outward displacement and compression of the damper 20, preventing the limiting block 17 from shifting position during the pulling process. Due to the engaging connection structure between the limiting block 17 and the scraping cleaning plate 16, the limiting block 17, when displacing outward, relaxes its engaging limit on the scraping cleaning plate 16, making it easier for the operator to pull the scraping cleaning plate 16 upward to remove it for disassembly and maintenance, thus improving the maintenance and cleaning efficiency of the device.
