Description

Technical Field

[0001] The utility model relates to the technical field of coal conveyor belt conveyors, in particular to a dust removal device for a coal conveyor belt conveyor. Background Art

[0002] Coal, referred to as coal, is the remains of ancient plants, buried under the strata, and carbonized fossil minerals produced under the pressure and temperature conditions of the earth's crust that isolates the air. It is mainly mined by humans as fuel. Coal plays an important role in modern industry, whether it is heavy industry or light industry; whether it is energy industry, metallurgical industry, chemical industry, machinery industry, or light textile industry, food industry, and transportation industry. Various industrial sectors consume a certain amount of coal to a certain extent, so some people call coal the "real food" of industry. It is one of the main energy sources used by the human world since the 18th century. Coal is often transported by belt conveyors, but a large amount of coal dust will be generated during the coal transportation process, which brings great harm to the environment and human health. Coal dust not only easily causes respiratory diseases, but also causes serious pollution to the environment.

[0003] According to the disclosure of Chinese utility model CN219708547U, a dust removal device for a coal conveyor belt conveyor is disclosed, including a coal conveyor, a lower hopper is fixedly installed on the upper end of the coal conveyor near the left side, a first roller is rotatably installed inside the lower hopper near the left side, four groups of evenly distributed coal tipping hoppers are fixedly connected to the outer periphery of the first roller, a second roller is rotatably installed inside the lower hopper near the right side, three groups of evenly distributed buffer plates are fixedly connected to the outer periphery of the second roller, the front ends of the first roller and the second roller are fixedly sleeved with pulleys, and eight groups of evenly distributed dry mist nozzles are arranged on the output pipe. Compared with the traditional dust removal method that simply treats the dust floating near the coal mine, the dust removal device for a coal conveyor belt conveyor described in the utility model is more thorough, and more water mist is attached to the surface of the coal mine, which is conducive to the continuous suppression effect in the subsequent transportation process, and the dust removal effect is better.

[0004] Since coal easily raises a large amount of ash, and the ash particles are relatively small, after long-term use of the dry mist nozzle for dust removal in the above-mentioned patent, the ash is likely to enter the nozzle, causing the nozzle to be blocked and affecting the normal use of the nozzle. The nozzle in the patent is fixed inside the dust reduction box, which is not convenient for cleaning or replacement, thereby affecting the normal dust reduction effect of the nozzle.

[0053] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0054] Embodiment 1

[0055] See also Figure 1-6A coal conveyor belt conveyor dust removal device comprises a main body component 1, wherein the main body component 1 comprises: a belt conveyor 11, a dust removal frame 12 is arranged on the top of the belt conveyor 11; a water tank 13 is arranged on the front side of the belt conveyor 11; a water pipe 14 is connected to the top of the water tank 13; a disassembly component 2 is arranged on the water pipe 14 and the dust removal frame 12, and the disassembly component 2 comprises: a fixing mechanism 21 is arranged on the front side of the dust removal frame 12; a base 22 is connected to the top of the water pipe 14; a blind hole 221 is opened inside the base 22; a push rod 23 is symmetrically plugged into the outer side wall of the base 22; a push plate 24 is arranged At one end of the push rod 23 away from the base 22; the connecting pipe 25 is movably connected to the base 22; the pressing plate 251 is slidably connected to the outside of the connecting pipe 25; the spring 26 is symmetrically arranged on the bottom surface of the pressing plate 251; the support plate 261 is arranged at the bottom end of the spring 26; the rod body 27 is symmetrically arranged on the bottom surface of the pressing plate 251; the fixing block 271 is arranged on the outer wall of the rod body 27; the fixing mechanism 21 is provided with a water pipe 215, the water pipe 215 is connected with the connecting pipe 25, and the bottom end of the water pipe 21 is located inside the dust removal frame 12 and is provided with a nozzle 16. The rod body 27 and the fixing block 271 are distributed in multiple groups around the circumference. The fixing mechanism 21 includes: a top plate 211, which is arranged on the top surface of the through groove opened on the front side of the dust removal frame 12; a spring 212, which is arranged on the bottom surface of the through groove opened on the front side of the dust removal frame 12; a bottom plate 213, which is arranged on the top of the spring 212; a slider 214, which is symmetrically arranged on the outer wall of the bottom plate 213, and a sliding groove is opened on the dust removal frame 12 for the slider 214 to move; and a pull rod 215, which is arranged at the bottom of the bottom plate 213.

[0056] Before use, first connect the water pipe 215 to the dust removal frame 12 through the fixing mechanism 21: pull the pull rod 215 downward, the pull rod 215 drives the bottom plate 213 to move downward to compress the spring 1 212, and the space between the bottom plate 213 and the top plate 211 becomes larger. When the bottom plate 213 is pulled to the lowest point, the water pipe 215 and the nozzle 16 are extended into the dust removal frame 12 from the through groove, and the pull rod 215 is released. The spring 1 212 drives the bottom plate 213 to fit the bottom of the water pipe 215. Since the bottom plate 213 is longer, the water pipe 215 is supported, and the bottom plate 213 is located on one side of the dust removal frame 12 with a plate body, which rises with the sliding of the bottom plate 213 to prevent coal ash from overflowing from the through groove. The slider 214 enhances the stability of the bottom plate 213 when it moves up and down. After installing the water pipe 2 15, the water pipe 2 15 and the water pipe 1 14 are installed by disassembling the component 2: align the connecting pipe 25 connected to the water pipe 2 15 with the base 22 on the water pipe 14, and abut the support plate 261 against the surface of the base 22. The operator presses the pressure plate 251 toward the base 22. The pressure plate 251 compresses the spring 3 26, driving the rod body 27 and the fixing block 271 to extend into the through groove at the top of the base 22. The fixing block 271 slides on the inner wall of the through groove until it enters the blind hole 221. The rod body 27 is limited by the fixing block 271, and the connection between the base 22 and the connecting pipe 25 is completed. Then, the coal is poured from the top into the dust removal frame 12. During the pouring process, coal ash flies. The dust removal frame 12 prevents the coal ash from overflowing. The staff starts the water pump in the water tank 13 and transports water to the nozzle 16 through the water pipe 14 and the water pipe 2 15. The nozzle 16 sprays water mist to wet the coal ash, reduce the kinetic energy of coal particles and coal ash, and thus reduce dust flying. The coal after dust suppression is continuously transported to the next place by the belt conveyor 11.

[0057] When the nozzle 16 is used for a long time, the coal powder with smaller particles is easy to clog the nozzle 16, affecting the normal use of the nozzle 16, so the nozzle 16 is disassembled: the staff presses the push plate 24 inward at the same time, and the push plate 24 pushes the push rod 23 into the base 22. When the push rod 23 continues to push inward, the fixed block 271 is pushed out from the blind hole 221, and the spring 3 26 uses the elastic force to bring the pressing plate 251 and the rod body 27 back to the direction of the connecting pipe 25, completing the separation of the connecting pipe 25 and the base 22. At this time, the pull rod 215 is pulled downward to take the water pipe 215 and the nozzle 16 out of the dust removal frame 12 for cleaning or replacement, which is convenient for the next use. The rod body 27 and the fixed block 271 are provided with multiple groups to improve the firmness of the connection between the base 22 and the connecting pipe 25.

[0058] Embodiment 2

[0059] On the basis of the first embodiment, an auxiliary function is added.

[0060] See also Figure 1-6, the inner bottom surface of the dust removal frame 12 is arc-shaped. The dust removal frame 12 is provided with an anti-blocking component 3, which includes: a motor 31, which is provided on the front side wall of the dust removal frame 12, and the output shaft of the motor 31 passes through and extends into the dust removal frame 12; a rotating shaft 32, which is rotatably connected to the inner side wall of the dust removal frame 12, and one end is fixedly connected to the output shaft of the motor 31; a rotating plate 33, which is circumferentially distributed outside the rotating shaft 32. A dustproof shell 4 is snap-fitted and connected to the tape machine 11.

[0061] The dust removal frame 12 with an arc bottom guides the falling coal to avoid a large impact force and dust at the coal drop point. The anti-blocking component 3 prevents the coal from being blocked in the dust removal frame 12: the staff starts the motor 31, the motor 31 drives the rotating shaft 32 to rotate, and the rotating plate 33 outside the rotating shaft 32 assists in conveying the coal to the surface of the belt conveyor 11 when rotating, preventing the coal from accumulating in the dust removal frame 12. The dustproof shell 4 conveys the coal on the top of the belt conveyor 11 in a closed manner, which can effectively reduce dust leakage and also avoid environmental pollution during the transportation process.
