Technical Field
[0001] This utility model belongs to the technical field of belt conveyor equipment and relates to a belt cleaning device. Background Technology
[0002] In recent years, with steady economic growth, belt conveyors have gained widespread popularity in industries such as metallurgy, coal, power, chemicals, ports, cement, papermaking, and food. However, during the operation of belt conveyors, as the conveyor belt transports materials forward, the materials easily adhere to the surface of the belt, forming sticky residue. Simultaneously, during the return stroke as the conveyor belt rotates, this residue falls downwards due to belt vibration and gravity, resulting in a large amount of material spilled under the entire conveyor belt. This not only easily leads to material waste but also poses a risk of injury to on-site workers, potentially causing accidents. Furthermore, the large amount of material adhering to the conveyor belt surface significantly reduces the conveyor's transport efficiency. Additionally, the large amount of material spilled under the entire conveyor belt results in a large amount of labor and difficulty in cleaning. Therefore, it is usually necessary to clean the surface of the conveyor belt during the operation of belt conveyors.
[0003] Currently, existing belt cleaning devices mainly use scrapers, single spray guns, or air guns to clean belts, but they still have the following shortcomings: (a1) While scrapers can remove most of the material on the belt, they are difficult to effectively clean the sticky material, resulting in material waste. Furthermore, to better remove the sticky material, the scraper usually needs to be pressed against the belt surface, which makes the scraper prone to wear and tear on the belt, leading to significant wear and tear, easy belt damage, greatly increased maintenance costs, and a significant reduction in production efficiency; (a2) When using a spray gun and spraying water to clean the belt, although it is beneficial for cleaning the sticky material on the belt surface, water splashing is likely to occur. The material transfers to the surface of other equipment, increasing the difficulty of cleaning. Moreover, the moisture remaining on the belt can cause corrosion and other adverse conditions if it is not removed in time. (a3) Using an air gun to clean the belt is difficult to remove the firmly adhered material, resulting in poor cleaning effect and difficulty in effectively cleaning the material on the surface of the belt. At the same time, the process of cleaning with air is prone to generating a large amount of dust, which will cause serious air pollution and deteriorate the quality of the working environment, thereby increasing the probability of pneumoconiosis. Although the use of a closed box structure can reduce dust spillage, it is difficult to avoid the spread of dust and it is easy to cause mechanical equipment blockage and difficult to clean. In addition, researchers have proposed a combined multi-functional belt cleaning device. Two sets of cleaners are symmetrically arranged at the bottom of the belt, with a nozzle positioned between the cleaners. An industrial hot air blower is located at the rear end of the belt, and a collection hopper is positioned directly below the cleaners and nozzles. Through the combined action of the cleaners and nozzles, material on the belt is swept into the collection hopper, and the industrial hot air blower dries the belt surface. However, this combined multi-functional belt cleaning device still has the following drawbacks: (b1) The scraper blades of the cleaners adhere to the lower surface of the belt, easily causing wear and tear, leading to a significant increase in maintenance costs and a substantial reduction in efficiency. (b2) The use of a single nozzle cannot effectively remove the material adhering to the belt surface. In particular, the nozzle direction is perpendicular to the belt, resulting in a small contact area between the spray water and the belt, leading to poor cleaning effect; (b3) The absence of a baffle plate causes irregular splashing of wastewater during the spraying process, resulting in wastewater transferring to other equipment surfaces, increasing cleaning difficulty, and this wastewater can easily cause corrosion and other adverse conditions on the belt and other equipment; (b4) After being cleaned by the scraper of the cleaner, the moisture content on the belt surface is low. Directly using an industrial fan to dry the belt at this time can easily generate dust. Therefore, obtaining a belt cleaning device with good cleaning effect, high cleaning efficiency, low material loss, and no dust generation is of great significance for improving the transportation efficiency and service life of belt conveyors.

[0016] Compared with the prior art, the advantages of this utility model are:
[0017] (1) In this utility model, several spray guns are arranged sequentially below the return belt along the transmission direction of the return belt, and air guns are set on the side of the return belt, with the air guns positioned between two spray guns. First, high-pressure water sprayed from the spray guns can be used to clean the material adhering to the return belt. While removing most of the adhering material, the material on the belt can also be wetted, reducing its adhesion. Then, high-pressure gas sprayed from the air guns can be used to blow away the remaining wetted material, further removing the remaining adhering material. At the same time, the water content in the belt can be significantly reduced under the action of high-pressure gas, which is conducive to reducing the temperature required for subsequent drying and improving drying efficiency. It can be seen that with the synergistic effect of the spray guns and air guns, the material adhering to the surface of the belt can be efficiently removed without damaging the belt, and the large amount of dust generation can be effectively avoided, which is conducive to reducing the probability of pneumoconiosis. In particular, with the cooperation of multiple sets of spray guns and air guns, the cleaning effect is better and the cleaning efficiency is higher. More importantly, by setting a front sewage baffle and top around the spray guns and air guns, The system consists of a front wastewater baffle, a top wastewater baffle, and side wastewater baffles, forming a wastewater blocking structure around the area to be cleaned on the return conveyor belt. A wastewater collection tank is located below this structure. This effectively prevents wastewater generated during cleaning from scattering randomly in all directions. Specifically, during spray gun cleaning, the front and top wastewater baffles prevent wastewater from scattering randomly in all directions; during air gun cleaning, the side wastewater baffles prevent wastewater from scattering to the sides. Therefore, the combined effect of the front, top, and side wastewater baffles effectively prevents wastewater from spilling onto the machinery, reducing the difficulty of cleaning equipment and instruments, lowering labor costs, and reducing the risk of corrosion from wastewater, thus extending the service life of the equipment. Furthermore, the wastewater blocking structure can collect wastewater and transfer it to the collection tank, reducing material waste and enabling centralized and simplified treatment of spilled materials. Therefore, the belt cleaning device of this utility model has the advantages of good cleaning effect, high cleaning efficiency, low material loss, no dust generation, and good adjustability. It can be widely used to clean the conveyor belt of belt conveyor and can meet the cleaning needs of different belts. It can efficiently remove materials from the surface of the belt without damaging the belt or generating dust, and can also realize the recycling of scattered materials. It has high use value and good application prospects.
[0018] (2) In this utility model, by setting an adjustable material baffle below the roller and the return belt, large pieces of material on the return belt can be effectively removed without contact with the return belt. This not only greatly reduces the cleaning difficulty of the subsequent spray gun and air gun, but also avoids these large pieces of material from damaging the related equipment below the return belt, which is conducive to improving the service life of the equipment. At the same time, the large pieces of material can be transferred to the material feed hopper under the guidance of the material baffle. Therefore, under the action of the material baffle, the cleaning difficulty can be reduced, the cleaning efficiency can be improved, and the loss of material can be reduced.

A side sewage baffle 7 is provided opposite the air guns 4, and the return belt 101 is located between the air guns 4 and the side sewage baffle 7. The front sewage baffle 2, top sewage baffle 5, and side sewage baffle 7 surround the area of the return belt 101 to be cleaned, forming a sewage blocking structure. A sewage collection tank 6 is located below the sewage blocking structure.
[0031] In this embodiment, the distance between two adjacent spray guns 3 and air guns 4 is ≥50cm, which refers to the distance between the vertical center points of the spray guns 3 and air guns 4, for example, the distance between them is 50cm; the distance between two adjacent spray guns 3 is equal, and the distance between two adjacent spray guns 3 is ≥1m, for example, the distance between them is 1m; the distance between two adjacent air guns 4 is equal; the distance between each air gun 4 and the return belt 101 is equal.
[0032] In this embodiment, the spray gun 3 and the air gun 4 are mounted on the base (not shown in the figure); the spray direction of the spray gun 3 is towards the bottom surface of the return belt 101, opposite to the transport direction of the return belt 101, and the angle between the spray direction of the spray gun 3 and the bottom surface of the return belt 101 is 20° to 30°, for example, 25°; the air direction of the air gun 4 is towards the bottom surface of the return belt 101, and the angle between the air direction of the air gun 4 and the bottom surface of the return belt 101 is 30° to 40°, for example, 35°.
[0033] In this embodiment, the spray gun 3 is also connected to a control cabinet for adjusting the water spray direction; the air gun 4 is also connected to a control cabinet for adjusting the air jet direction; the water inlet end of the spray gun 3 is also connected to a water pipe and a water pump; the air inlet end of the air gun 4 is also connected to an air pipe and an air pump. In this embodiment, the control cabinet for adjusting the water spray direction rotates up and down by a rotor driving a gear.
[0034] In this embodiment, by adjusting the water spray direction of the spray gun 3 and the air jet direction of the air gun 4 using the control cabinet, all-round cleaning of the return belt can be achieved, with good cleaning effect and high efficiency.
[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the front sewage baffle 2 is inclined upward and positioned below the return belt 101; the angle between the front sewage baffle 2 and the horizontal plane is 60° to 80°, for example, 70°; the distance between the top of the front sewage baffle 2 and the return belt 101 is 5cm to 7cm, for example, 6cm; the front sewage baffle 2 includes a base plate 21, and a water-blocking strip 22 is provided on the edge of the base plate 21. The water-blocking strip 22 is vertically positioned on the surface of the base plate 21, and the height of the water-blocking strip 22 is ≥5cm, for example, 5cm; the front sewage baffle 2 also has an overflow trough 23 on the side facing the spray gun 3; the overflow trough 23 is located in the middle of the front sewage baffle 2; the outlet of the overflow trough 23 is located in the collection hopper of the sewage collection tank 6; both the front sewage baffle 2 and the overflow trough 23 are provided with pulleys 24 at their bottoms; the pulleys 24 are located on the base (not shown in the figure). In this embodiment, a protruding overflow trough 23 is vertically arranged in the middle of the pre-sewage baffle 2. Simultaneously, the combined action of the base plate 21, the water-blocking strip 22, and the overflow trough 23 ensures that all splashed sewage falls onto the pre-sewage baffle 2, and that all sewage is collected and transferred to the sewage collection tank 6. Furthermore, pulleys 24 are provided at the bottom of the pre-sewage baffle 2 and the overflow trough 23, allowing the entire pre-sewage baffle 2 to move back and forth under the control of the control cabinet. The movement position of the baffle is determined by the spray distance generated by the spray pressure, ensuring that all sewage is collected. The wastewater is sprayed onto the baffle plate, and the distance it can move back and forth is set to a limit on the control cabinet to avoid excessive movement that could cause equipment failure. Furthermore, the stability of the structure is ensured by the combined action of the base plate 21, the baffle belt 22, the overflow trough 23, and the pulleys 24, utilizing a triangular support frame. In addition, to prevent wastewater from spilling between the pre-filter wastewater baffle 2 and the return belt 101, the distance between the top of the pre-filter wastewater baffle 2 and the return belt 101 is optimized to 5cm to 7cm. This also prevents the pre-filter wastewater baffle 2 from contacting the return belt, thus improving the belt's service life. In another embodiment, the pre-filter wastewater baffle 2 is inclined downwards and positioned below the return belt 101.
[0036] In this embodiment, the top sewage baffle 5 is detachably installed on the base (not shown in the figure); the top sewage baffle 5 is located between the return belt 101 and the conveyor belt 102; the top sewage baffle 5 is inclined downward above the return belt 101; the angle between the top sewage baffle 5 and the horizontal plane is 3° to 5°, for example, 4°; the top sewage baffle 5 includes a base plate 21, and the edge of the base plate 21 is provided with a water-blocking strip 22, which is vertically arranged on the surface of the base plate 21, and the height of the water-blocking strip 22 is ≥5cm, for example, 5cm; the outlet of the top sewage baffle 5 is located in the collection hopper of the sewage collection tank 6. In this embodiment, by optimizing the inclination angle of the top sewage baffle 5, it can be ensured that sewage flows into the sewage collection tank 6 at an angle.
[0037] In this embodiment, the side sewage baffle 7 is detachably installed on the base (not shown in the figure); the side sewage baffle 7 is arranged downward on one side of the return belt 101, so that the outlet of the side sewage baffle 7 is located in the collection hopper of the sewage collection tank 6; the angle between the side sewage baffle 7 and the horizontal plane is 85° to 90°, for example, the angle is 90°; the side sewage baffle 7 includes a base plate 21, and the edge of the base plate 21 is provided with a water-blocking strip 22, which is vertically arranged on the surface of the base plate 21, and the height of the water-blocking strip 22 is ≥5cm, for example, the height is 5cm.
[0038] like Figure 5 As shown, in this embodiment, the sewage collection tank 6 is detachably mounted on a base (not shown in the figure); the bottom of the sewage collection tank 6 slopes downwards, and a material deposition area 61 and a material collection area 62 are arranged sequentially from high to low; the angle between the bottom surface of the material deposition area 61 and the horizontal plane is 20° to 40°, for example, 30°; a material outlet 63 is also provided on the side wall of the material collection area 62; a clean water outlet 64 is also provided above the sewage collection tank 6. In this embodiment, by optimizing the inclination angle of the bottom surface of the material deposition area 61, the deposition of materials in the sewage collection tank 6 can be promoted. Figure 5 In the middle, the arrow indicates the direction in which sewage overflows from the baffle into the sewage collection tank, from top to bottom.
[0039] In this embodiment, a retractable and adjustable material baffle 1 and a drying device 8 are also included; the material baffle 1 is located at the front end and below the return belt 101; the drying device 8 is located at the tail end and below the return belt 101.
[0040] In this embodiment, the material baffle 1 and the drying device 8 are detachably mounted on the base (not shown in the figure); the material baffle 1 is inclined downwards and positioned below the roller 9; the material baffle 1 is connected to a material feed hopper at its outlet; when the material baffle 1 is perpendicular to the horizontal plane, the distance between the top of the material baffle 1 and the return belt 101 is ≥3cm, for example, 4cm; the bottom of the material baffle 1 is connected to a control cabinet for vertical movement. By inputting the movement distance on the operation page of the control cabinet, selecting the vertical movement knob, and clicking start, the vertical movement can be achieved. In this embodiment, by adjusting the distance between the top of the material baffle 1 and the return belt 101, the material baffle 1 can block large pieces of material on the return belt, and under the action of the material baffle 1, all the blocked material can fall into the material feed inlet. At the same time, the material baffle 1 can move up and down, effectively preventing it from contacting the top of the belt.
[0041] The working principle of the belt cleaning device of this utility model is as follows: During the operation of the belt, the distance between the material baffle and the belt is adjusted. The material baffle removes large pieces of material adhering to the belt. At this time, most of the material falls off the belt. The spray gun and air gun are turned on, and the spray gun sprays high-pressure water towards the front of the belt to clean the remaining adhering material. At this time, most of the adhering material falls off the belt, and the sewage is blocked by the front sewage baffle and sprayed onto the bottom plate and the water-blocking belt. Then, it flows into the sewage collection tank after being collected by the overflow trough. Further, the air gun is used to clean the remaining material. The spray gun emits high-pressure gas towards the other side of the belt, blowing away any remaining wet material. This serves two purposes: firstly, it pushes the wet material onto the side wastewater baffles; secondly, it dries the belt. In particular, the combined action of multiple spray guns and air guns efficiently removes material from the belt without damaging it or generating dust. Simultaneously, during the operation of the spray guns and air guns, the upward-sprayed wastewater collects on the top and side wastewater baffles, then flows into the wastewater collection tank, thus completing the efficient cleaning of the belt. Furthermore, since the air guns have already flushed most of the moisture from the belt into the side wastewater baffles, the drying device does not need to be set to a very high temperature to achieve perfect drying results, significantly reducing drying time and lowering production costs.
[0042] Compared with conventional belt cleaning devices, this utility model belt cleaning device has advantages such as better cleaning effect, higher cleaning efficiency, less material loss, no dust generation, and good adjustability. It can be widely used to clean the conveyor belts of belt conveyors and can meet the cleaning needs of different belts. It can efficiently remove materials from the belt surface without damaging the belt or generating dust, and can also realize the recycling of scattered materials. It has high use value and good application prospects. In addition, this utility model belt cleaning device is reasonably designed, highly practical, and easy to promote and use.
