Description

Technical Field

[0001] This invention relates to the field of dust suppression technology for coal conveyor belts, and in particular to a dust suppression device for coal conveyor belts. Background Technology

[0002] The application of coal conveyor belts can improve material conveying efficiency, reduce manual handling work, reduce labor intensity and production costs. At the same time, through reasonable design and configuration, it can also achieve automated control and safe operation. Coal conveyor belts are mainly composed of conveyor belts, drive devices, braking devices, idler roller groups, tensioning devices and redirection devices.

[0003] During the operation of coal conveyor belts, coal dust is generated as the coal falls due to the height difference between the belt and the coal-carrying device. This coal dust requires dust removal treatment, as it has a certain impact on the environment and human health. Therefore, dust suppression is an essential part of the coal transportation process. The dust suppression method used on coal conveyor belts generally uses spray nozzles to remove dust, causing water mist particles to collide, adhere, and agglomerate with dust particles, which then settle under their own gravity, thus achieving the dust suppression effect. However, existing nozzles cannot be adjusted in angle due to the influence of the working environment and equipment space. When the amount of coal dust generated varies, the nozzle angle will have a significant impact on the dust suppression effect. Summary of the Invention

[0004] In view of the problem that existing nozzles cannot be adjusted in angle during use due to the influence of the working environment and equipment space, resulting in poor dust suppression effect, the present invention is proposed.

[0005] Therefore, the purpose of this invention is to provide a dust suppression device for a coal conveyor belt.

[0010] As a preferred embodiment of the dust suppression device for coal conveyor belts of the present invention, the driven component includes a driven column, a first connecting spring disposed on the driven column, a connecting ring fixed on the driven column, a driving ring fixed on the connecting ring, a contact surface disposed on the driving ring, a connecting column disposed on the connecting pipe, and a slope surface disposed on the connecting column.

[0011] As a preferred embodiment of the dust suppression device for coal conveyor belts of the present invention, the driven column includes a column body, the column body is provided with a connecting hole, the column body is provided with a first contact surface, and the column body is provided with a second contact surface.

[0012] As a preferred embodiment of the dust suppression device for coal conveyor belts of the present invention, the rotating component includes a rotating disk, a rotating handle disposed on the rotating disk, a mounting surface disposed on the rotating disk, and an arc-shaped groove disposed on the rotating disk.

[0013] As a preferred embodiment of the dust suppression device for coal conveyor belts of the present invention, the limiting component includes a rotating plate, a limiting plate fixed on the rotating plate, a first limiting ring disposed on the mounting surface, a second limiting ring disposed on the first limiting ring, a second connecting spring disposed on the rotating rod, and a moving part disposed on the mounting surface.

[0014] As a preferred embodiment of the dust suppression device for coal conveyor belts of the present invention, the moving part includes a first moving block disposed on the mounting surface, a first clamping block disposed on the first moving block, a second moving block disposed on the mounting surface, a second clamping block fixed on the second moving block, and a circular hole disposed on the first moving block and the second moving block.

[0015] As a preferred embodiment of the dust suppression device for coal conveyor belts of the present invention, the first limiting ring includes a ring body, a first inclined surface on the ring body, a second inclined surface on the ring body, and a slot on the ring body.

[0016] As a preferred embodiment of the dust suppression device for coal conveyor belts of the present invention, the first clamping block includes a block body, the block body is provided with an inclined groove, and the block body is provided with a guide pin.

[0017] The beneficial effects of the dust suppression device for coal conveyor belts of the present invention are as follows: The present invention installs a dust suppression hood at the end of the coal conveyor belt where the coal falls. This hood performs the first step of dust suppression, as coal dust disperses instantly when the coal falls. The hood blocks some of this dispersion. Simultaneously, nozzles are connected to the inner wall of the dust suppression hood via connecting components. The water mist sprayed from these nozzles further suppresses the coal dust. Furthermore, since the nozzles are movably connected to the dust suppression hood via connecting components, a driven column on a rotating rod can drive the driven column to move. During the movement of the driven column… In the process, the slope at the bottom of the connecting column comes into contact with the first and second contact surfaces on the driven column. During this process, the driven column can drive the connecting column to move up and down. Under the action of the connecting column, the first and second connecting balls can rotate in the circular groove, thereby causing the nozzle angle to change. When the angle between the nozzle and the belt conveyor increases, the spray range of the nozzle will increase, and the dust suppression effect will not be affected when the amount of coal dust increases. When the angle between the nozzle and the belt conveyor decreases, the distance between the water mist and the coal dust will decrease when the amount of coal dust decreases, which can improve the dust suppression effect.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1, referring to Figures 1 to 3 This is the first embodiment of the present invention. This embodiment provides a dust suppression device for a coal conveyor belt, which includes a conveying mechanism 100, which includes a support base 101, a belt 102 disposed on the support base 101, the belt 102 being mounted on the support base 101, and a motor 103 disposed on the support base 101. The motor 103 is fixedly mounted on one side of the support base 101, and the belt 102 can be rotated by the motor 103, so that the belt 102 can be used to transport coal.

[0031] The adjusting mechanism 200 includes a dust suppression hood 201 fixed to a support base 101. The dust suppression hood 201 is fixedly installed at the material discharge end of the support base 101. The dust suppression hood 201 can prevent some of the coal dust generated when the coal falls. Two mounting boxes 202 are fixed to the dust suppression hood 201, and the two mounting boxes 202 are respectively fixedly connected to one side of the dust suppression hood 201. A nozzle 203 is connected to the dust suppression hood 201 and is movably connected to the side of the dust suppression hood 201 through a connecting member 204. The connecting member 204 is movably connected to the inside of the side of the dust suppression hood 201 and is disposed on the connecting member 204. The drive component 205 is fixedly installed inside the mounting box 202. The drive component 205 can drive the driven component 206 to move. The driven component 206 is fixedly installed inside the mounting box 202 and can drive the nozzle 203 to move. The rotating component 207 is fixedly connected to the top of the mounting box 202 and is fixedly installed on the rotating component 207. The limiting component 208 is fixedly installed inside the rotating component 207 and can make the nozzle 203 stay at multiple angle positions.

[0032] Specifically, the connecting component 204 includes a circular groove 204a disposed on the dust suppression cover 201, the circular groove 204a being formed inside the dust suppression cover 201, and two symmetrical circular grooves 204a being formed on the dust suppression cover 201; a connecting pipe 204b disposed on the nozzle 203, the connecting pipe 204b being threadedly connected to the nozzle 203; and a telescopic rod 204c fixed to the connecting pipe 204b, one end of the telescopic rod 204c being fixedly connected to the connecting pipe 204b, and the other end of the connecting pipe 204b being connected to the circular groove 204a through a first connecting ball 204d and fixed to the telescopic rod 204a. The first connecting ball 204d on the telescopic rod 204c is fixedly connected to one end of the telescopic rod 204c. The fixing rod 204e is fixedly connected to the connecting pipe 204b, and the installation position of the fixing rod 204e is symmetrical with the installation position of the telescopic rod 204c. The other end of the fixing rod 204e is movably connected to the circular groove 204a through the second connecting ball 204f. The second connecting ball 204f is fixedly installed on the fixing rod 204e.

[0033] Furthermore, the drive component 205 includes a mounting tube 205a disposed on the mounting box 202, the mounting tube 205a being fixedly mounted on the bottom surface inside the mounting box 202, an insertion hole 205b disposed on the mounting tube 205a and formed on the outer surface of the mounting tube 205a, a rotating rod 205c connected to the mounting box 202 and rotatably connected to the mounting box 202, a connecting block 205d fixed to the bottom of the rotating rod 205c and located inside the mounting tube 205a and rotatable within the mounting tube 205a, a drive column 205e disposed on the connecting block 205d and fixedly connected to the bottom of the connecting block 205d, and a drive surface 205f disposed on the drive column 205e and formed on the outer surface of the drive column 205e, through which the driven column 206a can be driven to move.

[0034] Operating Procedure: During the transportation of coal using belt conveyor 102, coal dust is generated. To protect the ecological environment, dust suppression is necessary while belt conveyor 102 is operating. Effective dust suppression requires focusing on the areas most prone to dust generation. Due to the height difference between belt conveyor 102 and the coal-carrying device, a large amount of coal dust is generated as the coal falls. Therefore, installing a dust suppression hood 201 on the support base 101 at the coal drop end effectively prevents large-scale dust dispersion. Simultaneously, nozzles 203 are installed on both sides of the dust suppression hood 201. The water mist sprayed from the nozzles 203 effectively... To suppress coal dust, one end of the nozzle 203 is threadedly connected to a connecting pipe 204b. A telescopic rod 204c and a fixed rod 204e are fixedly installed on the connection. The telescopic rod 204c and the fixed rod 204e are movably connected to the inside of the side of the dust suppression hood 201 through a first connecting ball 204d and a second connecting ball 204f, respectively. The angle of the nozzle 203 can be freely adjusted through the connecting component 204. The mounting pipe 205a is fixedly connected to the mounting box 202. A connecting block 205d is fixedly connected to the bottom of the rotating rod 205c. Since the connecting block 205d is located inside the mounting pipe 205a, when the rotating rod 205c rotates, it will drive the driven column 206a to move, thereby causing the nozzle 203 to change angle.

[0035] Example 2, refer to Figures 3 to 6This is the second embodiment of the present invention. Unlike the previous embodiment, the driven component 206 includes a driven post 206a, which is slidably connected within the mounting tube 205a. A first connecting spring 206b is disposed on the driven post 206a, with one end fixedly connected to one end of the driven post 206a and the other end fixedly mounted on the inner wall of the mounting tube 205a. A connecting ring 206c is fixedly attached to the driven post 206a and threadedly connected to it. Because the connecting ring 206c is threadedly connected to the driven post 206a, it can move freely. Adjust the position of the connecting ring 206c on the driven post 206a, fix the driving ring 206d on the connecting ring 206c, and drive the driving ring 206d to the connecting ring 206c. The diameter of the driving ring 206d is larger than the diameter of the connecting ring 206c. The contact surface 206e on the driving ring 206d is adapted to the driving surface 205f on the driving post 205e. The connecting post 206f on the connecting pipe 204b is fixedly connected to one end of the connecting pipe 204b. The slope 206g on the connecting post 206f is formed at the bottom of the connecting post 206f.

[0036] Specifically, the driven column 206a includes a column body 206a-1, a connecting hole 206a-2 on the column body 206a-1, the connecting hole 206a-2 being located at one end of the column body 206a-1, the connecting hole 206a-2 being used to install the first connecting spring 206b, a first contact surface 206a-3 on the column body 206a-1, and a second contact surface 206a-4 on the column body 206a-1, with a height difference between the first contact surface 206a-3 and the second contact surface 206a-4. When the slope 206g on the connecting column 206f interacts with the first contact surface 206a-3 and the second contact surface 206a-4, it will drive the connecting column 206f to move up and down, and the angle of the nozzle 203 can be adjusted during the movement.

[0037] Furthermore, the rotating component 207 includes a rotating disk 207a, which is fixedly connected to the top of the mounting box 202, a rotating handle 207b disposed on the rotating disk 207a, one end of the rotating handle 207b being fixedly connected to the rotating rod 205c, a mounting surface 207c disposed on the rotating disk 207a, and an arc-shaped groove 207d disposed on the rotating disk 207a. The arc-shaped groove 207d is formed on the outer surface of the rotating disk 207a, and the rotating handle 207b passes through the arc-shaped groove 207d and is connected to the rotation.

[0038] Operation process: When the handle 207b is rotated, the rotating rod 205c will rotate inside the mounting tube 205a. The drive column 205e at the bottom of the rotating rod 205c will also rotate synchronously with the rotating rod 205c. When the drive column 205e rotates, when the drive surface 205f on the drive column 205e contacts the contact surface 206e on the drive ring 206d, it will drive the driven column 206a to slide inside the mounting tube 205a. During the sliding process, the driven column... The first contact surface 206a-3 and the second contact surface 206a-4 on 206a will successively contact the slope surface 206g on the connecting column 206f. When the slope surface 206g contacts the first contact surface 206a-3, it will move downward. When the slope surface 206g contacts the second contact surface 206a-4, the connecting column 206f will move upward. During the up-and-down movement of the connecting column 206f, it will drive the first connecting ball 204d and the second connecting ball 204f. As the nozzle 203 rotates within the circular groove 204a, its angle changes. Since one end of the first connecting ball 204d is connected to the telescopic rod 204c, the rotation of the first connecting ball 204d within the circular groove 204a shortens the telescopic rod 204c. However, under the action of the fixed rod 204e, the first connecting ball 204d will not detach from the circular groove 204a. Therefore, under the action of the telescopic rod 204c, the range of rotation of the first connecting ball and the second connecting ball 204f within the circular groove 204a expands, thereby increasing the range of adjustment of the nozzle 203's angle. The larger the angle between the nozzle 203 and the belt 102, the larger the range of water mist spraying. Even with a large amount of coal dust, the dust suppression effect remains undiminished. When the amount of coal dust is small, the angle between the nozzle 203 and the belt 102 decreases, reducing the contact distance between the water mist and the coal dust, thus improving the dust suppression effect.

[0039] The rest of the structure is the same as in Example 1.

[0040] Example 3, referring to Figures 7 to 8This is the third embodiment of the present invention. Unlike the previous embodiment, the limiting component 208 includes a rotating plate 208a, which is fixedly connected to the rotating rod 205c. Two limiting plates 208b are fixedly mounted on the rotating plate 208a in a symmetrical manner. The two limiting plates 208b form a group. Two sets of first limiting rings 208c are provided on the rotating plate 208a and mounted on the mounting surface 207c. The first limiting rings 208c are fixedly connected to the mounting surface of the rotating disk 207a. On surface 207c, a second limiting ring 208d is provided on the first limiting ring 208c. The second limiting ring 208d is fixedly connected to the first limiting ring 208c. The nozzle 203 can be fixed in a specified position through the first limiting ring 208c and the second limiting ring 208d. A second connecting spring 208e is provided on the rotating rod 205c. The second connecting spring 208e is installed inside the rotating rod 205c. A moving part 208f is provided on the mounting surface 207c. The moving part 208f is fixedly installed on the rotating plate 208a.

[0041] Specifically, the movable component 208f includes a first movable block 208f-1 disposed on the mounting surface 207c, the first movable block 208f-1 being movably connected to the gap between the two limiting plates 208b; a first clamping block 208f-2 disposed on the first movable block 208f-1, the first clamping block 208f-2 being fixedly installed on the side of the first movable block 208f-1, the first clamping block 208f-2 being adapted to the groove on the first limiting ring 208c; and a second movable block 208f-3 disposed on the mounting surface 207c. -3 is movably connected to the gap between another set of limiting plates 208b, and the second clamping block 208f-4 is fixed on the second moving block 208f-3. The second clamping block 208f-4 is fixedly connected to the side of the second moving block 208f-3, and a circular hole 208f-5 is provided on the first moving block 208f-1 and the second moving block 208f-3. The circular hole 208f-5 is opened on the side away from the first moving block 208f-1 and the second moving block 208f-3 where the first clamping block 208f-2 and the second clamping block 208f-4 are installed.

[0042] The first limiting ring 208c includes a ring body 208c-1, a first inclined surface 208c-2, and a second inclined surface 208c-3. Both the first inclined surface 208c-2 and the second inclined surface 208c-3 are formed on the inner wall of the ring body 208c-1. The ring body 208c-1 also has a slot 208c-4, which is formed between the first inclined surface 208c-2 and the second inclined surface 208c-3. The second limiting ring 208d also has the first inclined surface 208c-2, the second inclined surface 208c-3, and the slot 208c-4, but the slots 208c-4 of the first limiting ring 208c and the second limiting ring 208d are staggered.

[0043] Furthermore, the first clamping block 208f-2 includes a block body 208f-2a, a groove 208f-2b on the block body 208f-2a, the groove 208f-2b being formed on the top of the block body 208f-2a, and a guide pin 208f-2c on the block body 208f-2a, the bottom of the guide pin 208f-2c being fixedly installed on the top of the rotating plate 208a. Meanwhile, the first moving block 208f-1 and the second moving block 208f-3 are symmetrically arranged. The guide pin 208f-2c can prevent the first moving block 208f-1 and the second moving block 208f-3 from shifting when moving between the two limiting plates 208b, thereby enabling the first clamping block 208f-2 and the second clamping block 208f-4 to engage better.

[0044] The rest of the structure is the same as in Example 2.

[0045] Operation process: When the handle 207b is rotated, the rotating rod 205c rotates synchronously with the handle 207b. At the same time, the rotating plate 208a on the rotating rod 205c also rotates with the rotating rod 205c. When rotating on the rotating plate 208a, the first moving block 208f-1 and the second moving block 208f-3 on the rotating plate 208a will cause the first locking block 208f-2 and the second locking block 208f-4 to move on the first limiting ring 208c and the second limiting ring 208d. When the first locking block 208f-2 is locked in the slot 208c-4 on the first limiting ring 208c, it will pull the second connecting spring 208e, thereby causing the second locking block 208f-4 to be locked in the slot 208c-4 on the second limiting ring 208d. Therefore, under the action of the first clamping block 208f-2, the second clamping block 208f-4 and the second connecting spring 208e, the first moving block 208f-1 and the second moving block 208f-3 can slide between the two limiting plates 208b. During the sliding process, the guide pin 208f-2c will limit the first moving block 208f-1 and the second moving block 208f-3. When the first clamping block 208f-2 and the second clamping block 208f-4 are respectively locked in the slots 208c-4 on the first limiting ring 208c and the second limiting ring 208d, the rotation of the handle 207b is stopped. At this time, under the action of the first clamping block 208f-2 and the second clamping block 208f-4, the nozzle 203 can be fixed in a certain position and will not move.
