Description

Technical Field

[0001] The present invention relates to the technical field of belt conveying, and particularly relates to an intelligent belt conveyor brush cleaner and its usage method. Background Art

[0002] In the process of coal mining and transportation, belt conveyors are key material conveying equipment. Particulate materials such as coal ash, coal slime, and crushed coal blocks often adhere to the surface of their belts. If these attachments are not cleaned in time, it will not only reduce the conveying efficiency, but may also cause belt deviation, increased wear, and even lead to safety accidents.

[0003] Brush cleaners are widely used in the cleaning work of belt conveyors to remove residual materials on the belt surface. However, in actual use, the existing belt conveyor brush cleaners are independently controlled, resulting in the need for operators to individually control the start and stop of the cleaner, and they must always pay attention to the running state of the belt. Moreover, the existing cleaners mainly target the cleaning of coal ash and fine particles, have limited processing capacity for large coal blocks, easily cause coal blocks to roll on the coal ash conveyor belt, and cannot separately collect and utilize large coal blocks, affecting the collection efficiency, consuming the energy of workers, increasing labor costs, and affecting the practicality of the cleaner.

[0059] The present invention also provides a usage method of an intelligent belt conveyor brush cleaning device, including the following specific usage steps:

[0060] Step 1: The speed monitor on the coal mine conveyor is connected to the power supply of the belt shaft motor. When the coal mine conveyor starts, the speed monitor transmits the detected belt speed signal on the coal mine conveyor to the control circuit. The control circuit compares the actual speed with the set value. When it is detected that the belt speed is lower than or higher than the set value range, the control circuit will send out an alarm signal and trigger an emergency stop protection measure to stop. When it is detected that the belt speed of the coal mine conveyor is within the set value range, the speed monitor outputs to the control circuit, and the output information is transmitted to the belt shaft motor through the controller, so as to control the running speed of the coal ash conveyor belt on the collection mechanism and the brush cleaning speed of the cleaning brush, so that the brush cleaning and the belt run synchronously;

[0061] Step 2: Meanwhile, the cleaning mechanism sweeps the coal ash and particles on the belt of the coal mine conveyor onto the arc-shaped plate. Through the micro-inclined plane at the top of the arc-shaped plate, the dust and small particles can roll onto the coal ash conveyor belt and be collected by the ash collecting box at one end of the fixed frame through the transmission of the coal ash conveyor belt;

[0062] Step 3: The movement of the upper belt of the coal mine conveyor drives the rotation of the wear-resistant wheel, causing its auxiliary rod to rotate. Through the third synchronization component, its rotating head drives the support ring and the rotating rod to rotate, so that the cleaning brush sweeps the medium-sized coal lumps on the top of the arc-shaped plate. Under the rotation of the rotating component, the large coal lumps are crushed by the steel wires. The crushed small particles fall onto the coal ash conveyor belt, and the large coal lumps are squeezed between multiple steel wires and are conveyed to the inner cavity of the rotating ring through the rotation of the spiral conveying brush, and fall into the inner cavity of the bearing box through the feeding pipe and are collected.

[0063] The technical effects and advantages of the present invention:

[0064] (1) The present invention utilizes the cooperation setting of the collection mechanism, the cleaning mechanism and the coal block feeding mechanism. Through the arc-shaped plate, it is convenient for the cleaning mechanism to sweep the coal ash particles on the belt of the coal mine conveyor to the top of the arc-shaped plate. Through the spiral conveying brush and the steel wires on the coal block feeding mechanism, the large coal blocks are separately conveyed and the coal sludge and medium-sized coal fragments are crushed, preventing them from rolling on the collection mechanism. Moreover, it can realize the intelligent synchronous drive of the cleaning mechanism and the coal mine conveyor without manual intervention, reducing the labor intensity of workers and improving the practicability of the cleaner;

[0065] (2) The present invention utilizes the speed monitor and the controller on the collection mechanism to realize the synchronous operation of the cleaning mechanism and the coal mine conveyor. At the same time, it avoids the wear caused by the mismatched rotation speed of the brush. Through the connection with the coal mine conveyor by the connection mechanism, the wear-resistant wheel is in contact with the belt of the coal mine conveyor for frictional drive, and with the elastic adjustment of the pressing component, it ensures stable transmission and realizes the synchronous operation of the coal block feeding mechanism and the coal mine conveyor, reducing the consumption of resources;

[0066] (3) The present invention utilizes the cooperation setting of the arc-shaped plate and the coal block feeding mechanism, so that the large coal blocks on the arc-shaped plate can be crushed and conveyed. The coal block feeding mechanism does not affect the small coal fragments and coal ash from falling onto the coal ash conveyor belt of the collection mechanism, facilitating the separate collection and utilization of the large coal blocks, improving the sorting efficiency, and being able to stably clean the belt on the coal mine conveyor, effectively removing fine particles such as coal sludge and coal ash, and improving the cleaning efficiency.

Detailed implementation manners

[0077] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0078] The present invention provides an intelligent belt conveyor roller brush cleaner as Figure 1-9 shown, which includes a coal mine conveyor 1. The coal mine conveyor 1 is an existing belt conveyor machine, and the coal mine conveyor 1 is composed of structures such as a frame, a belt, and a driving device. The coal mine conveyor 1 is an existing common device, and its specific structure description will not be elaborated here. A collection mechanism 2 is installed at the end of the coal mine conveyor 1. It also includes a cleaning mechanism 3, an arc plate 4, a coal block pressing mechanism 5, a bearing box 6, and a connection mechanism 7. The cleaning mechanism 3 is installed at one end of the collection mechanism 2, and the cleaning mechanism 3 is used for cleaning coal ash fragments on the surface of the coal mine conveyor 1. The arc plate 4 is installed on one side of the cleaning mechanism 3. The bottom of the arc plate 4 is of an arc structure, and the top of the arc plate 4 is slightly inclined downward. The arc plate 4 is used for conveying powder slag onto the collection mechanism 2. The coal block pressing mechanism 5 is installed on the top of the arc plate 4, and the coal block pressing mechanism 5 is used for the separate transportation of large coal blocks and the crushing of medium-sized coal blocks. The bearing box 6 is installed at one end of the coal block pressing mechanism 5, and the connection mechanism 7 is installed at the other end of the coal block pressing mechanism 5. The connection mechanism 7 is used for the synchronous drive of the coal mine conveyor 1 and the coal block pressing mechanism 5, which is convenient for reducing resource waste, and realizes the treatment of large coal blocks and medium-sized coal blocks by the coal block pressing mechanism 5, reduces the risk of large coal blocks and medium-sized coal blocks rolling off the collection mechanism 2, and is convenient for the separate collection of large coal blocks.

[0079] Among them, the collection mechanism 2 includes a fixed frame 21, a coal ash conveyor belt 22, a conveyor shaft 23, a connecting shaft 24, a first gear 25, a second gear 26, a first synchronizing component 27, a second synchronizing component 28, and a belt shaft motor 29. The fixed frame 21 is fixed to one end of the coal mine conveyor 1, that is, the fixed frame 21 is fixed to the frame of the coal mine conveyor 1, and the belt of the coal mine conveyor 1 is arranged below the fixed frame 21. A dust collection box is fixed to the bottom of one end of the fixed frame 21. The coal ash conveyor belt 22 is arranged inside the fixed frame 21. The coal ash conveyor belt 22 is used for the transmission of coal ash and small broken particles. The dust collection box is located below one end of the coal ash conveyor belt 22. The dust collection box is used for the collection of coal ash and small broken particles. Two conveyor shafts 23 are respectively arranged at both ends inside the coal ash conveyor belt 22. The coal ash conveyor belt 22 is connected to the two conveyor shafts 23 through an existing tensioning structure. When one of the conveyor shafts 23 rotates, it can drive the stable movement of the coal ash conveyor belt 22. Two connecting shafts 24 are rotatably supported inside the fixed frame 21 through brackets, and the two connecting shafts 24 penetrate inside the coal ash conveyor belt 22. The first gear 25 is fixed to one end of one of the conveyor shafts 23. The second gear 26 is fixed to one end of one of the connecting shafts 24. The outer wall of the second gear 26 is meshed and connected to the first gear 25, which is convenient for the synchronous rotation drive between one of the conveyor shafts 23 and one of the connecting shafts 24. The first synchronizing component 27 is installed between the two connecting shafts 24. The second synchronizing component 28 is installed at one end of one of the connecting shafts 24. The belt shaft motor 29 is fixed to one end of the fixed frame 21. The second synchronizing component 28 is installed between one of the connecting shafts 24 and the output shaft of the belt shaft motor 29. The coal mine conveyor 1 is connected with a speed monitor through a control circuit. The belt shaft motor 29 is connected to the speed monitor through a controller, which is convenient for the synchronous drive between the belt shaft motor 29 and the coal mine conveyor 1. The speed monitor is a contact type belt stall speed monitor, equipped with a contact wheel type slip switch. When the belt runs, the contact wheel rotates, driving the internal pulse disk or sensor to generate a signal. The signal is processed and compared with a preset speed value to monitor the belt speed. For example, the belt stall slip switch JYB / RC-C. When the belt speed is lower than 80% of the normal speed or higher than 20% of the normal speed, the control power supply of the coal mine conveyor 1 can trip and stop. And the synchronizing component is an existing finished belt drive component. By starting the belt shaft motor 29, the connecting shaft 24 and the conveyor shaft 23 can rotate synchronously, so that the coal ash conveyor belt 22 can stably convey small coal ash particles.

[0080] In addition, the cleaning mechanism 3 includes a cleaning roller brush 31 and a chain assembly 32. Both ends of the cleaning roller brush 31 are respectively installed on the other end of the fixed frame 21 through bearing seats. The arc-shaped plate 4 fits on the outer wall of the cleaning roller brush 31, and the arc-shaped plate 4 is fixed to the bottom of the fixed frame 21 by screws. The chain assembly 32 is installed between the cleaning roller brush 31 and another connecting shaft 24. The chain assembly 32 is an existing finished chain drive assembly, which facilitates the connecting shaft 24 to drive the cleaning roller brush 31 to rotate synchronously, so that the movement of the upper belt of the coal mine conveyor 1 can drive the cleaning roller brush 31 to rotate synchronously for cleaning, effectively cleaning particulate materials such as coal slime and coal ash attached to the belt surface, without the need to start and stop the cleaner separately, reducing the wear of the cleaning roller brush 31 caused by fast rotation and reducing the consumption of resources.

[0081] Meanwhile, the coal block feeding mechanism 5 includes a support assembly 51, a rotating assembly 52, a feeding assembly 53, a support ring 54 and a rotating head 55. The support assembly 51 is installed on one side of the fixed frame 21. The rotating assembly 52 is arranged on the top of the arc-shaped plate 4. The rotating assembly 52 rotates between the support assembly 51 and the connecting mechanism 7. The feeding assembly 53 is installed at one end of the support assembly 51. The feeding assembly 53 is arranged above the bearing box 6, which facilitates the large particle coal blocks that can be caught in the inner cavity of the rotating assembly 52 to fall into the inner cavity of the bearing box 6 through the feeding assembly 53 and be collected separately. The support ring 54 is fixed to the other end of the support assembly 51. The rotating head 55 is fixedly connected to the inner wall bracket of the support ring 54.

[0082] Specifically, the support assembly 51 includes an L-shaped frame 511, an arc-shaped block 512, a ball 513, a rotating ring 514 and a support rod 515. The L-shaped frame 511 is fixed to one side of the fixed frame 21 by bolts. The arc-shaped block 512 is fixed to the top of the L-shaped frame 511. A plurality of balls 513 are equidistantly and rotatably embedded in the inner wall of the arc-shaped block 512. The rotating ring 514 rolls in the inner cavity of the arc-shaped block 512 through the balls 513.

The rotating assembly 52 is installed between the rotating ring 514 and the support ring 54. The feeding assembly 53 is arranged at one end of the rotating ring 514. A plurality of support rods 515 are fixed to the inner wall of the rotating ring 514, and the support rods 515 are connected to the rotating assembly 52, improving the connection stability between the rotating ring 514 and the rotating assembly 52.

[0083] More specifically, the rotating assembly 52 includes a rotating rod 521, a spiral conveying brush 522 and steel wires 523. One end of the rotating rod 521 is fixedly connected to the rotating head 55, and the other end of the rotating rod 521 is fixedly connected to one end of a plurality of support rods 515.

A plurality of steel wires 523 are fixedly arranged in an annular array between the rotating ring 514 and the support ring 54. A plurality of steel wires 523 are rotatably connected to the top of the arc-shaped plate 4. The steel wires 523 are galvanized steel wires 523 with relatively high toughness and elasticity. When the plurality of steel wires 523 rotate on the surface of the arc-shaped plate 4, the steel wires 523 can roll the outer wall of the coal block, and can make large coal blocks get stuck between two adjacent steel wires 523. And through the rotation of the rotating rod 521, under the push of the spiral conveying brush 522, it is convenient for the coal block to move towards one end of the feeding assembly 53, so that the coal block can be fed through the feeding assembly 53, which is convenient for the separate collection of large coal blocks.

[0084] Among them, the feeding assembly 53 includes a positioning box 531 and a feeding pipe 532. The positioning box 531 is rotatably connected to one end of the rotating ring 514 through a bearing.

The feeding pipe 532 is a flexible cloth pipe. Through the arrangement of the feeding pipe 532, the impact of the coal block falling into the inner cavity of the bearing box 6 is reduced, and the noise is reduced.

[0085] Furthermore, the connecting mechanism 7 includes a support frame 71, a connecting ring 72, a protective box 73, an auxiliary rod 74, a third synchronization component 75, a wear-resistant wheel 76, a pressing-down component 77, and a screw rod 78. The support frame 71 is rotatably inserted through both ends of the rotating head 55 via bearings. The bottom of the support frame 71 is fixedly connected to the other side of the fixed frame 21. The connecting ring 72 rotates via a bearing at one end of the support frame 71. Through the support frame 71 and the support component 51, stable rotational support is provided for the rotating component 52. The protective box 73 is fixed to the outer wall of the connecting ring 72, facilitating the protective box 73 to rotate obliquely at the end of the support frame 71. Both ends of the auxiliary rod 74 are rotatably inserted through the inner wall of the protective box 73 via bearings. The third synchronization component 75 is installed between the auxiliary rod 74 and the rotating head 55. The third synchronization component 75 includes two existing synchronous wheels and a synchronous belt. The two synchronous wheels are respectively fixed to the outer wall of the auxiliary rod 74 and the middle part of the rotating head 55. The synchronous belt is arranged between the two synchronous wheels. The wear-resistant wheel 76 is fixed to one end of the auxiliary rod 74. The wear-resistant wheel 76 is arranged inside the protective box 73. The pressing-down component 77 is arranged on the top of the protective box 73. The pressing-down component 77 is used for elastic pressing-down of the protective box 73, enabling the wear-resistant wheel 76 to be in close contact with the surface of the belt of the coal mine conveyor 1. The screw rod 78 is threadedly inserted through the other side of the fixed frame 21. The bottom of the screw rod 78 is connected to the pressing-down component 77. By manually rotating the screw rod 78, small-range height adjustment of the pressing-down component 77 is facilitated, suitable for the close fitting of the wear-resistant wheel 76 with the belts of coal mine conveyors 1 with different heights within a small range of changes.

[0086] Further, the pressing component 77 includes a U-shaped block 771, an anti-slip strip 772, a compression spring 773, a limiting rod 774, a pressing block 775 and a positioning rod 776. The U-shaped block 771 is arranged above the protective box 73. The anti-slip strip 772 is fixed to the bottom of the U-shaped block 771. The anti-slip strip 772 is used for pressing against the outer wall of the top of the protective box 73. The compression spring 773 is fixed to the top of the U-shaped block 771. The limiting rod 774 is sleeved in the inner cavity of the compression spring 773. The limiting rod 774 is slidably inserted through the middle of the U-shaped block 771. The pressing block 775 is fixed to the top of the compression spring 773. The top of the limiting rod 774 is fixedly connected to the bottom of the pressing block 775. Through the arrangement of the limiting rod 774, the compression spring 773 can be stably used, which is convenient for the compression spring 773 to apply an elastic downward pressure to the U-shaped block 771, facilitating the close fit of the wear-resistant wheel 76 with the surface of the belt of the coal mine conveyor 1. Under the action of friction, the belt moves, which can drive the wear-resistant wheel 76 to rotate, enabling the rotating head 55 to rotate stably. The bottom of the screw rod 78 is rotatably inserted through the middle of the pressing block 775. A plurality of positioning rods 776 are fixed to the top of the pressing block 775. The positioning rods 776 are slidably inserted through the other side of the fixed frame 21. Through the positioning rods 776, the stability of the position of the pressing block 775 is improved, facilitating the screw rod 78 to moderately adjust the position of the pressing block 775 and improving the stability during the use of the roller brush cleaner.

[0087] Usage method of the present invention:

[0088] The speed monitor on the coal mine conveyor 1 is connected to the power supply of the belt shaft motor 29. When the coal mine conveyor 1 starts, the speed monitor transmits the detected belt speed signal of the coal mine conveyor 1 to the control circuit. The control circuit compares the actual speed with the set value. When it is detected that the belt speed is lower than or higher than the set value range, the control circuit will send an alarm signal and trigger an emergency shutdown protection measure to stop the machine. When it is detected that the belt speed of the coal mine conveyor 1 is within the set value range, the speed monitor outputs to the control circuit, and the output information is transmitted to the belt shaft motor 29 through the controller, thereby controlling the running speed of the coal ash conveyor belt 22 on the collection mechanism 2 and the roller brush cleaning speed of the cleaning roller brush 31, so that the roller brush cleaning runs synchronously with the belt;

[0089] Meanwhile, the cleaning mechanism 3 sweeps the coal ash and particles on the belt of the coal mine conveyor 1 onto the arc-shaped plate 4. Through the micro-inclined surface at the top of the arc-shaped plate 4, the dust and small particles can roll onto the coal ash conveyor belt 22 and are collected by the ash collection box at one end of the fixed frame 21 through the transmission of the coal ash conveyor belt 22;

[0090] The movement of the upper belt of the coal mine conveyor 1 drives the rotation of the wear-resistant wheel 76, causing its auxiliary rod 74 to rotate. Through the third synchronization component 75, the rotating head 55 drives the support ring 54 and the rotating rod 521 to rotate, so that the cleaning brush 31 sweeps the medium-sized coal lumps on the top of the arc-shaped plate 4. Under the rotation of the rotating component 52, the coal lumps are crushed by the steel wires 523. The crushed lower particles fall onto the coal ash conveyor belt 22, and the large coal lumps are squeezed between multiple steel wires 523 and are conveyed to the inner cavity of the rotating ring 514 through the rotation of the spiral conveying brush 522, and then fall into the inner cavity of the bearing box 6 through the feeding pipe 532 for collection.

[0091] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
