Description

Technical Field

[0001] This utility model relates to the field of conveyor cleaning technology, and in particular to a coal accumulation removal device based on a belt conveyor. Background Technology

[0002] From the perspective of equipment installation environment, the layout of belt conveyors often needs to be adapted to the on-site production layout and space conditions. In scenarios such as underground mines and factory workshops, the installation space for the conveyor head, tail, and middle body is usually quite narrow due to factors such as the cross-sectional size of the roadway, the spacing of surrounding equipment, and the layout of the building structure. This space limitation not only imposes strict requirements on the selection and installation of the conveyor itself, but also brings great challenges to the configuration and operation of subsequent coal accumulation removal devices. Traditional large-scale coal accumulation cleaning equipment is difficult to install and deploy in narrow areas due to its large size and high operating space requirements; while small cleaning devices often face problems such as limited cleaning range and high risk of interference with other components of the conveyor, resulting in a significant reduction in the adaptability of coal accumulation removal solutions. At the current level of coal accumulation cleaning technology, the cleaning methods commonly used in the industry are mainly based on various types of cleaners, including head cleaners, tail cleaners, and empty section cleaners. Their core principle is mostly to scrape or brush off the residual material on the surface of the conveyor belt by the contact between components such as scrapers and brushes and the belt surface.

[0003] However, due to factors such as vibration, belt misalignment, and material viscosity and particle size differences during conveyor belt operation, some materials cannot be effectively scraped off and continue to adhere to the conveyor belt surface as it moves. For residual materials at the bottom of the conveyor belt return section, the existing empty section cleaners have limited cleaning power and coverage, especially in areas where bottom idlers are densely distributed under the conveyor belt. The cleaning components cannot penetrate into the gaps between the idlers, causing materials to accumulate on the idler surface and idler supports. Therefore, this application aims to solve the problems of residual materials caused by belt vibration, misalignment, and material characteristics, as well as the problem of insufficient cleaning and easy accumulation of materials in the gaps between idlers by empty section cleaners. A coal accumulation removal device based on a belt conveyor is proposed. Utility Model Content

[0004] To overcome the problems of existing conveyors being affected by conveyor belt vibration, deviation, and the stickiness and particle size of materials, some materials are difficult to completely remove and continue to move with the belt. Existing empty section cleaners have limited cleaning force and coverage in the return section, especially in reaching the gaps between the bottom idlers, resulting in material accumulation at the idlers and supports.

[0005] The technical solution of this utility model is as follows: a coal accumulation removal device based on a belt conveyor, including a coal accumulation frame and a rotating assembly connected to the outer surface of the coal accumulation frame. A cylinder assembly is connected to the rotating assembly. The rotating assembly is used to drive the cylinder assembly to rotate along a vertical through-axis. A liquid inlet pipe is rotatably connected to the cylinder assembly. The liquid inlet pipe penetrates the shell wall of the cylinder assembly and connects to the inner cavity of the cylinder assembly. A liquid passage pipe is connected to the input end of the liquid inlet pipe, and the input end of the liquid passage pipe is connected to a water source.

[0006] Preferably, the cylinder assembly includes a connector that is rotatably connected to the liquid inlet pipe, an outer cover cylinder is attached to the outer surface of the connector, and a fixing sleeve is attached to the bottom end face of the outer cover cylinder.

[0007] Preferably, a fixing ring is rotatably connected to the outer surface of the liquid inlet pipe, an inner sleeve is rotatably connected to the fixing ring, a combination strip is connected to the inner wall of the inner sleeve, and a spray head is connected to the inner sleeve.

[0008] Preferably, a connecting shaft is connected to both end faces of the inner sleeve, and a fixing block is fitted on the outer surface of the connecting shaft. The fixing block is rotatably connected to the connecting shaft. A hydraulic push rod is connected to the upper end face of the fixing block, and a connecting rod plate is connected to the hydraulic push rod. A second motor is connected to one of the fixing blocks, and the output shaft of the second motor is connected to the connecting shaft on its corresponding fixing block.

[0009] Preferably, the rotating assembly includes a wheel frame connected to a coal accumulation frame, a rotating wheel rotatably connected to the wheel frame, meshing teeth connected to the rotating wheel, and a first motor connected to the outer surface of the wheel frame.

[0010] Preferably, a meshing wheel is connected to the output shaft of the first motor, the meshing wheel meshes with meshing teeth, and a fixed frame is connected to the upper end face of the rotating wheel, the fixed frame being connected to the outer cover cylinder.

[0011] Preferably, an air inlet pipe is connected to the outer surface of the outer casing, the air inlet pipe penetrates the shell wall of the outer casing and communicates with the inner cavity of the outer casing, an air supply pipe is connected to the input end of the air inlet pipe, a high-pressure hot air blower is connected to the input end of the air supply pipe, and an installation plate is connected to the lower end of the high-pressure hot air blower.

[0012] The beneficial effects of this utility model are:

[0013] 1. When it is necessary to clean the coal accumulated on the coal storage rack, clean water from the water source is transported to the inside of the liquid inlet pipe through the liquid inlet pipe. Under the action of gravity, the clean water inside the liquid inlet pipe is sent into the inside of the cylinder assembly, so as to discharge it through the spray head on the cylinder assembly. This allows the coal accumulated on the coal storage rack to move along the coal storage rack, thereby alleviating the coal accumulation phenomenon.

[0014] 2. The inner sleeve is driven to rotate by the second motor, and the rotation drives the inner sleeve to rotate around the central axis of the outer sleeve in the inner cavity of the outer sleeve, so that the cleaning liquid remaining on the inner wall of the inner sleeve can be thrown out under the action of centrifugal force, so as to prevent the cleaning liquid from remaining inside the outer sleeve.

[0015] 3. A high-pressure hot air blower is used to blow heated air into the inner cavity of the outer sleeve through the air inlet and outlet pipes. This heats and dries the cleaning fluid remaining on the inner wall of the inner sleeve, preventing the accumulation of cleaning fluid on the inner wall of the inner sleeve.

A cylinder assembly is connected to the rotating assembly, which drives the cylinder assembly to rotate along a vertical through-axis. An inlet pipe 304 is rotatably connected to the cylinder assembly, which penetrates the shell wall of the cylinder assembly and connects to the inner cavity of the cylinder assembly. The input end of the inlet pipe 304 is connected to a liquid passage pipe 308, which is connected to a water source.

[0025] When it is necessary to clean the coal accumulated on the coal storage rack 1, clean water from the water source is transported to the inside of the liquid inlet pipe 304 through the liquid inlet pipe 308. Under the action of gravity, the clean water inside the liquid inlet pipe 304 is sent into the inside of the cylinder assembly, so as to be discharged through the spray head 307 on the cylinder assembly. This allows the coal accumulated on the coal storage rack 1 to move along the coal storage rack 1, thereby alleviating the coal accumulation phenomenon.

[0026] Furthermore, the rotating assembly includes a wheel frame 201, which is connected to the coal accumulation frame 1. A rotating wheel 202 is rotatably connected to the wheel frame 201, and meshing teeth 203 are connected to the rotating wheel 202. A first motor 205 is connected to the outer surface of the wheel frame 201.

[0027] Among them, the first motor 205 is generally a stepper motor of model 42CM02 used in conjunction with it;

[0028] The first motor 205 can drive the meshing wheel 204 to rotate, and the rotating meshing wheel 204 can drive the rotating wheel 202 to rotate around its own center line, so as to drive the outer cover cylinder 301 connected to the fixed frame 206 to swing, thereby expanding the spray range of the spray head 307.

[0029] Furthermore, a meshing wheel 204 is connected to the output shaft of the first motor 205, the meshing wheel 204 meshes with the meshing teeth 203, and a fixing frame 206 is connected to the upper end face of the rotating wheel 202, the fixing frame 206 is connected to the outer cover cylinder 301.

[0036] Among them, the second motor 405 is generally a stepper motor of model 17HS08-1004S used in conjunction with it;

[0037] When the second motor 405 rotates, it can drive the inner sleeve 306 to rotate. The rotation drives the inner sleeve 306 to rotate around the central axis of the outer sleeve 301 within the inner cavity of the outer sleeve 301. This allows the cleaning fluid remaining on the inner wall of the inner sleeve 306 to be thrown out under the action of centrifugal force, thus preventing the cleaning fluid from remaining inside the outer sleeve 301.
