Description

Technical Field

[0001] This invention relates to the field of conveyor belt cleaning technology, and in particular to a belt conveyor under roller device with cleaning function. Background Technology

[0002] A belt conveyor is a machine that uses friction to continuously transport materials. It mainly consists of a frame, conveyor belt, idlers, rollers, tensioning devices, and transmission devices. Belt conveyors are widely used in the material conveying stage of various industries. Some wet, fine powder, or sticky materials will adhere to the working surface and move with the return belt. If these residues are not effectively removed, they will become the source of a series of subsequent problems.

[0003] Currently, most belt conveyor belts are cleaned primarily by scrapers at their ends, while other types of cleaning devices are usually installed at their bottom. However, since belt conveyors typically have many lower idlers installed at their bottom, installing other cleaning devices would be affected by the lower idlers, resulting in limited installation space. Therefore, a belt conveyor lower idler device with sweeping and cleaning functions is proposed.

[0004] In the existing technology, the cleaning device integrated on the lower idler roller is a spiral blade. The cleaning function of this type of blade is relatively simple, and it still relies on scraping to achieve the cleaning effect. However, there are gaps and grooves on the surface of the conveyor belt to increase the friction between the material and the conveyor belt. The material remaining in these gaps and grooves cannot be removed by the blade. In addition, as the working time of the belt conveyor increases, more material will adhere to the surface of the blade, which will affect the subsequent cleaning work. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The following is combined Figures 1 to 11 As shown, an embodiment of the present invention provides a belt conveyor lower idler roller device with a cleaning function, comprising: Roller 901, two auger blades 902 are fixedly sleeved on the side wall of roller 901, and the two auger blades 902 rotate in opposite directions. The auger blades 902 are used to scrape off the material on the surface of the conveyor belt. Multiple cleaning components are fixed to the inner wall of the drum 901 in a spiral path. The cleaning components are used to clean the material on the surface of the conveyor belt. The fixed component is rotatably connected to the roller 901. Multiple transmission components are connected to fixed components, and all transmission components are located inside the drum 901. Each transmission component corresponds to a cleaning component. Water tank 101 is connected to a fixed assembly, and the lower half of roller 901 is located inside water tank 101. Filter assemblies are provided on both sides of water tank 101, and the filter assemblies are used to treat sewage. Two cleaning components are installed inside the water tank 101. The two cleaning components are used to clean the surfaces of the two auger blades 902 respectively. A flushing assembly is connected to a stationary assembly. The flushing assembly is used to flush the surface of the conveyor belt with gas and liquid. The power assembly is connected to the stationary assembly and is also connected to the flushing assembly and the drum 901. The power assembly is used to drive the flushing assembly to work and the drum 901 to rotate. The cleaning components include: The fixing plate 910 has two fixing blocks 912 on its top, and both fixing blocks 912 are fixed to the inner wall of the roller 901. Multiple transmission rods 905 are rotatably connected to the fixed plate 910, and each transmission rod 905 penetrates the outer wall of the roller 901. A brush 906 is fixed to the top of each transmission rod 905.

[0026] During the rotation of the drum 901, the auger blades 902 and the brush 906 are driven to rotate. The rotating auger blades 902 scrape off the material on the surface of the conveyor belt, while the brush 906 cleans the material in the grooves on the surface of the conveyor belt. During this process, the brush 906, located above the drum 901, rotates on its own as it follows the rotation of the drum 901, ensuring that the material in the grooves on the surface of the conveyor belt is thoroughly cleaned, thereby improving the cleaning efficiency.

[0027] Furthermore, the cleaning components also include: Two connecting plates 913 are fixed to the bottom of the fixing plate 910; Rotating shaft 911, rotating shaft 911 and two connecting plates 913 are rotatably connected; Multiple first bevel gears 914 are fixed to the bottom ends of multiple transmission rods 905 respectively; Multiple second bevel gears 915 are fixedly sleeved on the rotating shaft 911, and multiple first bevel gears 914 and multiple second bevel gears 915 mesh one-to-one; The spur gear 909 is fixed at the end of the rotating shaft 911 and is compatible with the transmission assembly.

[0028] During the rotation of the spur gear 909, the shaft 911 is driven to rotate, and the first bevel gear 914, the second bevel gear 915 and the transmission rod 905 drive the brush 906 to rotate. Therefore, when the roller 901 rotates, the brush 906 rotates around the axis of the roller 901. At the same time, the brush 906 rotates on its own axis.

[0029] Furthermore, the fixing components include: Support rod 903, with mounting brackets 301 fixed at both ends of support rod 903; Two bearings 904 are fixedly mounted on the mounting bracket 301, and the two bearings 904 are respectively fixed to both ends of the roller 901.

[0030] Furthermore, the transmission components include: Two fixing brackets 907 are fixed to the side wall of the support rod 903, and the two fixing brackets 907 are distributed vertically. Two circular arc racks 908 are fixed on two fixing brackets 907 respectively, and the circular arc racks 908 and spur gears 909 are compatible.

[0031] During the rotation of the roller 901, the fixed plate 910 drives the various transmission rods 905 and the brush 906 to rotate, so that the brush 906 at the top comes into contact with the conveyor belt. As the brush 906 approaches the conveyor belt, the spur gear 909 moves along the surface of the arc rack 908, and then the arc rack 908 drives the spur gear 909 to rotate.

[0032] Furthermore, the rinsing assembly includes: Air pipe 402 and water pipe 403 are located on both sides of roller 901. Both ends of air pipe 402 and water pipe 403 are fixed with second support plates 401, and multiple second support plates 401 are fixed with adjacent mounting brackets 301. Multiple exhaust holes 405 are opened on the side wall of air pipe 402, and multiple nozzles 404 are installed through the side wall of water pipe 403. Two storage tanks 501 are fixed together with two second support plates 401. A first piston 505 is slidably disposed inside each storage tank 501. A spring 506 is fixed to the side wall of each first piston 505, and the two springs 506 are respectively fixed to the inner wall of the two storage tanks 501. Two first connecting pipes 502 are respectively installed through the ends of the two storage tanks 501; Two flow valves 503 are connected to two first connecting pipes 502 respectively, and the two flow valves 503 are connected to the air pipe 402 and the water pipe 403 respectively. Two second connecting pipes 504 are respectively installed through the ends of the two storage tanks 501; Two conveying components are connected to two filter components respectively, and the two conveying components are connected to two second connecting pipes 504 respectively.

[0033] When gas or liquid is injected into storage tank 501, the internal pressure gradually increases. When the pressure inside storage tank 501 reaches a certain level, the flow valve 503 is opened. By using the movement of the first piston 505 and the extension and contraction of the spring 506, storage tank 501 can buffer the liquid or gas, so that the gas or liquid flow rate output through flow valve 503 is constant.

[0034] Furthermore, the filtering components include: The filter box 102 is connected to the water tank 101. An installation frame 105 is provided inside the filter box 102. The top of the installation frame 105 is an inclined structure. Filter 106 is fixed to the inner wall of mounting frame 105; The negative pressure seat 104 is fixed to the bottom of the filter box 102, and the top of the negative pressure seat 104 has multiple through holes. Water level gauge 103 is fixed to the inner wall of filter box 102; The third solenoid valve 203 is connected to the negative pressure seat 104; The second solenoid valve 201 is disposed through the side wall of the filter box 102, and the end of the second solenoid valve 201 is located within the space enclosed by the mounting frame 105 and the filter box 102.

[0035] After the wastewater generated during cleaning enters the filter box 102, larger impurities fall onto the negative pressure seat 104 under the action of gravity, while smaller impurities rise with the water flow and are filtered by the filter screen 106, thereby reducing the filtration pressure of the filter screen 106 and also reducing the maintenance frequency of this device.

[0036] Furthermore, the conveying components include: Mounting rod 601 is fixed to the side wall of filter box 102; Sleeve 603, and a second piston 607 is slidably disposed inside sleeve 603; Sleeve rod 604 is fixed on the side wall of the second piston 607; Two connecting blocks 602 are fixed to the ends of the sleeve 603 and the sleeve rod 604 respectively. One connecting block 602 is rotatably connected to the mounting rod 601, and the other connecting block 602 is rotatably provided with a connecting shaft 701. The first check valve 605 and the second check valve 606 are both disposed through the side wall of the sleeve 603.

[0037] When the third transmission wheel 806 rotates, it drives the flywheel 702 to rotate through the transmission shaft 802. Then, through the rotation of the connecting shaft 701 and the corresponding connecting block 602, as well as another connecting block 602 and the mounting rod 601, the sleeve rod 604 and the sleeve 603 are periodically extended and retracted. During this process, the second piston 607 moves back and forth in the sleeve 603. During the reciprocating motion of the second piston 607, water filtered by the filter screen 106 in the filter box 102 is drawn into the corresponding sleeve 603 through the corresponding second one-way valve 606, the second three-way pipe 202, and the second solenoid valve 201. Then, it is injected into the corresponding storage tank 501 through the corresponding first one-way valve 605 and the corresponding second connecting pipe 504. Similarly, another second piston 607 moves reciprocatingly in the sleeve 603 to inject gas into the corresponding storage tank 501.

[0038] Furthermore, the two second connecting pipes 504 are respectively connected to the two first one-way valves 605. One of the second one-way valves 606 is provided with a second three-way pipe 202 at its end. The other two ends of the second three-way pipe 202 are respectively connected to the two second solenoid valves 201. The two third solenoid valves 203 are each provided with a first three-way pipe 107. The top of the water tank 101 is provided with two pipe bodies 114. The two pipe bodies 114 are each fixed with a first support plate 111, and the first support plate 111 is fixed to the top of the water tank 101. The ends of the two pipe bodies 114 are each provided with multiple output pipes 113. The ends of the two pipe bodies 114 are connected to a water supply three-way pipe 112. The other end of the water supply three-way pipe 112 is provided with a first solenoid valve 115.

[0039] Furthermore, the powertrain components include: Motor 801 is fixed to the side wall of one of the mounting brackets 301; The drive shaft 802 is rotatably mounted on the side wall of the mounting bracket 301 near the motor 801, and the drive shaft 802 passes through the mounting bracket 301. The third transmission wheel 806 is fixed to the transmission shaft 802; The first transmission wheel 803 is fixed to the end of the drum 901; Two second transmission wheels 805 are fixed to the output shaft of the motor 801; The first transmission belt 804 is sleeved on one of the second transmission pulleys 805 and the first transmission pulley 803; The second transmission belt 807 is fitted onto another second transmission wheel 805 and a third transmission wheel 806; The flywheel 702 is fixed to the end of the drive shaft 802, and the connecting shaft 701 is fixed to the eccentric part of the side wall of the flywheel 702. A balance block 703 is fixed to the side wall of the flywheel 702.

[0040] The balance weight 703 can be used to ensure the stability of the flywheel 702 during rotation.

[0041] Furthermore, the cleaning components include: Two shafts 116 are rotatably mounted on the inner wall of the water tank 101; Two connecting rollers 108 are respectively fixedly sleeved on two shafts 116; Belt 109 is fitted onto two connecting rollers 108; Multiple cleaning plates 110 are fixed at equal intervals on the surface of the connecting roller 108.

[0042] The roller 901 rotates continuously, causing the surface of the auger blade 902 to come into contact with the cleaning plate 110. In conjunction with the action of the connecting roller 108, the shaft 116 and the belt 109, the cleaning plate 110 can move freely. Since the auger blade 902 has a spiral structure, during the rotation of the auger blade 902, multiple cleaning plates 110 continuously come into contact with the surface of the auger blade 902 to achieve the cleaning work of the auger blade 902.

[0043] The specific working method is as follows: When in use, firstly, the pump is fixed to the frame of the conveyor by two mounting brackets 301. The inlet of the mud pump is connected to the first three-way pipe 107, and the first solenoid valve 115 is connected to the outlet of the water pump. When the first solenoid valve 115 is turned on, the water pump injects water into the pipe body 114 through the first solenoid valve 115 and the water supply three-way pipe 112, and then injects it into the water tank 101 through the outlet pipe 113. The water level in the filter box 102 is detected by the water level gauge 103, and the first solenoid valve 115 is controlled by the automation system to keep the water level in the filter box 102 and the water tank 101 at a suitable position. During the operation of the conveyor, the scraper at its end removes most of the adhering material; When the switch of motor 801 is turned on, motor 801 drives two second transmission wheels 805 to rotate, and then drives the first transmission wheel 803 and the third transmission wheel 806 to rotate through the first transmission belt 804 and the second transmission belt 807. When the third transmission wheel 806 rotates, it drives the flywheel 702 to rotate through the transmission shaft 802. Then, through the rotation of the connecting shaft 701 and the corresponding connecting block 602, as well as another connecting block 602 and the mounting rod 601, the sleeve rod 604 and the sleeve 603 are periodically extended and retracted. During this process, the second piston 607 moves back and forth in the sleeve 603. During the reciprocating motion of one of the second pistons 607, water filtered by the filter screen 106 in the filter box 102 is drawn into the corresponding sleeve 603 through the corresponding second one-way valve 606, the second three-way pipe 202, and the second solenoid valve 201. Then, it is injected into the corresponding storage tank 501 through the corresponding first one-way valve 605 and the corresponding second connecting pipe 504, so that the spring 506 in the storage tank 501 is compressed. When the water pressure in the storage tank 501 reaches a certain level, it enters the water pipe 403 through the corresponding first connecting pipe 502 and the flow valve 503, and is then output through the nozzle 404. The water flow sprayed from the nozzle 404 is used to clean the conveyor belt of the conveyor, and the conveyor belt is initially cleaned. Supported by the mounting frame 301, support rod 903, and bearing 904, and with the rotation of the first transmission wheel 803, the drum 901 rotates. During the rotation of the drum 901, the auger blades 902 are driven to rotate. Through the rotation state of the auger blades 902 and their spiral structure, when the conveyor belt moves past the auger blades 902, the material above them is pushed to one side of the conveyor belt. Through the two auger blades 902, the material on the conveyor belt is pushed to both sides of the conveyor belt, further cleaning the surface of the conveyor belt. During the rotation of the drum 901, the fixed plate 910 drives the various transmission rods 905 and the brush 906 to rotate, so that the brush 906 at the top comes into contact with the conveyor belt. As the brush 906 approaches the conveyor belt, the spur gear 909 moves along the surface of the arc rack 908, and then the arc rack 908 drives the spur gear 909 to rotate. During the rotation of the spur gear 909, the rotating shaft 911 is driven to rotate, and then the first bevel gear 914, the second bevel gear 915 and the transmission rod 905 drive the brush 906 to rotate. Therefore, when the drum 901 rotates, the brush 906 rotates around the axis of the drum 901. At the same time, the brush 906 rotates on its own axis, which further cleans the conveyor belt thoroughly, and the residual material in the grooves on the surface of the conveyor belt is also thoroughly cleaned. During the reciprocating motion of the other second piston 607, external gas is drawn into the sleeve 603 through the corresponding second one-way valve 606, and then injected into the corresponding storage tank 501 through the corresponding first one-way valve 605 and the corresponding second connecting pipe 504, so that the spring 506 in the storage tank 501 is compressed. When the gas pressure in the storage tank 501 reaches a certain level, it enters the air pipe 402 through the corresponding first connecting pipe 502 and flow valve 503, and then is output through the exhaust port 405, so that the gas blows the surface of the conveyor belt of the conveyor and blows out the residual moisture on the surface of the conveyor belt, so as to avoid a large amount of moisture remaining on the surface of the conveyor belt, which would worsen the material adhesion. During the cleaning process of the conveyor belt, the roller 901 rotates continuously so that the surface of the auger blade 902 comes into contact with the cleaning plate 110. With the help of the connecting roller 108, the shaft 116 and the belt 109, the cleaning plate 110 can move freely. Since the auger blade 902 has a spiral structure, during the rotation of the auger blade 902, multiple cleaning plates 110 continuously come into contact with the surface of the auger blade 902 to achieve the cleaning work of the auger blade 902. When the brush 906 rotates to the bottom of the roller 901, the spur gear 909 contacts the arc rack 908 located below, so that the brush 906 can rotate in the water in the water tank 101 to achieve the cleaning work of the brush 906. When the water in the water tank 101 and the filter box 102 needs cleaning, the sewage in the filter box 102 can be extracted in sequence. When extracting the sewage, the second solenoid valve 201 and the third solenoid valve 203 on the other filter box 102 need to be closed. After the second solenoid valve 201 and the third solenoid valve 203 on the filter box 102 are closed, the water flows to the other filter box 102. At this time, the water carrying impurities moves to the negative pressure seat 104 in the filter box 102. Then, the mud pump is turned on. When the mud pump is working, the sewage in the corresponding filter box 102 is extracted through the first three-way pipe 107, the third solenoid valve 203 in the connected state, and the corresponding negative pressure seat 104, so as to maintain the water quality in the water tank 101 and the filter box 102, thereby ensuring the cleaning effect on the auger blades 902 and the brush 906.
