Automatic pressurizing adjusting device for ash belt sweeper

Abstract

This invention discloses an automatic pressurization and adjustment device for a dust removal belt cleaner, comprising a conveying assembly. A scraper assembly is fixedly installed at the bottom inside the conveying assembly, and air injection assemblies are fixedly installed at the front and rear ends of one side of the scraper assembly. This invention injects air into the sealed chamber through the continuous and repeated movement of two sealing rings. This allows the top of the scraper to clean water from the bottom of the conveyor belt, preventing water from contaminating the ground. Simultaneously, the top of the scraper is in prolonged contact with the bottom of the conveyor belt, increasing wear on the scraper top. The two sealing rings continuously inject gas from the two fixed cylinders into the sealed chamber, pushing the scraper upwards under air pressure. This avoids the need for regular manual adjustments due to severe scraper wear, reducing labor costs. Furthermore, it ensures that the top of the scraper remains in constant contact with the bottom of the conveyor belt, thereby improving the effectiveness of cleaning water from the bottom of the conveyor belt.

Description

Technical Field

[0001] This invention relates to the field of industrial automation technology, and in particular to an automatic pressure adjustment device for a dust removal belt cleaner. Background Technology

[0002] A thermal power plant is a factory that uses combustible materials (such as coal) as fuel to produce electricity. Coal is known as black gold and the food of industry. It has been one of the main energy sources used by mankind since the 18th century. Although the value of coal has declined significantly since the beginning of the 21st century, it will still be an indispensable energy source for human production and life for a long time to come. The security of coal supply is also one of the most important aspects of my country's energy security. Coal slag is a type of industrial solid waste. It is the waste residue discharged from thermal power plants, industrial and domestic boilers and other equipment that burn coal.

[0003] Currently, most power plants use coal as their main fuel. Coal combustion produces a large amount of coal slag, which is then transported by conveyor belts after cooling. This transportation process generates dust, which is characterized by its small particle size, light weight, strong adhesion, and tendency to caking when wet. Therefore, dust adheres to the rubber conveyor belt during transport. Existing methods mostly use alloy scrapers to clean the surface, but these are not very effective at removing dust from the return path of the conveyor belt, resulting in a large accumulation of dust under the belt along the return route. Especially after passing the lower horizontal idler rollers, the dust is stirred up by the belt's vibration and scattered on the ground, polluting the environment. Therefore, an automatic pressure adjustment device for the ash removal belt cleaner is proposed, which can improve the cleaning effect of dust adhering to the surface of the rubber conveyor belt. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] Therefore, the technical problem to be solved by the present invention is that dust adheres to the conveyor belt during the conveying of coal slag using a rubber conveyor belt, resulting in a large amount of ash accumulation under the belt along the return route of the conveyor.

[0007] To solve the above technical problems, the present invention provides the following technical solution: an automatic pressurization adjustment device for a dust removal belt sweeper, including an adjustment mechanism, wherein the adjustment mechanism includes a conveying component, a transmission component, a drive component, a water injection component, a stabilizing component, an air injection component, a scraper component, and a water spraying component;

[0008] The conveying assembly includes a fixed frame, a first rotating roller and a second rotating roller disposed inside the fixed frame, a conveyor belt disposed on the first rotating roller and the second rotating roller, and a drain pipe disposed on the fixed frame.

[0009] As a preferred embodiment of the automatic pressure adjustment device for the dust removal belt cleaner of the present invention, the transmission component includes a second transmission ring disposed on the second rotating roller, a transmission belt disposed on the two second transmission rings, and a first transmission ring disposed on the fixed frame.

[0010] As a preferred embodiment of the automatic pressurization adjustment device for the dust removal belt cleaner of the present invention, the driving component includes a first connecting rod disposed on the two first transmission rings, a fixed ring disposed on the first connecting rod, a connecting ring disposed on the two fixed rings, and a second connecting rod disposed on the two connecting rings.

[0011] As a preferred embodiment of the automatic pressurization adjustment device for the dust removal belt cleaner of the present invention, the air injection component includes a fixed plate disposed on the fixed frame, a fixed cylinder disposed on the fixed plate, a sealing ring disposed on the two fixed cylinders, a first transmission rod disposed on the two sealing rings, a sealing plate disposed on the two fixed cylinders, a first one-way valve disposed on the two sealing plates, a second one-way valve disposed on the two fixed cylinders, and a second transmission rod disposed on the two first transmission rods.

[0012] As a preferred embodiment of the automatic pressurization adjustment device for the dust removal belt cleaner of the present invention, the scraper assembly includes a sealing chamber disposed on the fixed frame, a scraper disposed on the sealing chamber, a diversion chamber disposed on the scraper, an air jet hole disposed on the scraper, a third one-way valve disposed on the diversion chamber, and a spring disposed on the scraper.

[0013] As a preferred embodiment of the automatic pressurization adjustment device for the dust removal belt cleaner of the present invention, the stabilizing component includes a third connecting rod disposed on the fixed frame, a transmission gear disposed on the third connecting rod, a first connecting block disposed on the scraper, a first rack disposed on the two first connecting blocks, and a second sliding groove disposed on the fixed frame.

[0014] As a preferred embodiment of the automatic pressurization adjustment device for the dust removal belt cleaner of the present invention, the stabilizing component further includes four first sliding grooves disposed on the fixed frame, second connecting blocks disposed on the four first sliding grooves, a stabilizing frame disposed on the four second connecting blocks, a second rack disposed on the two second connecting blocks at the left end, and a compression wheel disposed on the stabilizing frame.

[0015] As a preferred embodiment of the automatic pressurization adjustment device for the dust removal belt cleaner of the present invention, the water spraying assembly includes an annular pipe disposed on the fixed frame, spray holes disposed on the annular pipe, a stabilizing ring disposed on the fixed frame, and a third transmission rod disposed on the two stabilizing rings.

[0016] As a preferred embodiment of the automatic pressurization adjustment device for the dust removal belt cleaner of the present invention, the water spraying assembly further includes roller brushes disposed on the two third transmission rods and a limiting groove disposed on the fixed frame.

[0017] As a preferred embodiment of the automatic pressurization adjustment device for the dust removal belt cleaner of the present invention, the water injection component includes a receiving plate disposed on the fixed frame, a water pump disposed on the receiving plate, a connecting pipe disposed on the water pump, and a connecting pipe disposed on the water pump.

[0018] The beneficial effects of this invention are as follows: This invention continuously injects air into the sealed chamber through the repeated movement of two sealing rings. The increasing air pressure inside the sealed chamber pushes the scraper upwards, and the top of the scraper contacts the bottom of the conveyor belt. This allows the top of the scraper to clean the water at the bottom of the conveyor belt, preventing water from contaminating the ground. At the same time, the top of the scraper is in contact with the bottom of the conveyor belt for a long time, thereby increasing the wear of the scraper top. The two sealing rings continuously inject gas from the two fixed cylinders into the sealed chamber, and the air pressure pushes the scraper upwards, thus avoiding the need for regular manual adjustment due to severe scraper wear, reducing labor costs. At the same time, it ensures that the top of the scraper is always in contact with the bottom of the conveyor belt, thereby improving the water cleaning effect at the bottom of the conveyor belt.

[0019] The beneficial effects of this invention are as follows: This invention uses the continuous and repeated movement of two sealing rings to compress the gas inside the two fixed cylinders into the sealed chamber. The gas pressure inside the sealed chamber continuously increases, pushing the scraper upward and compressing the two springs. The top of the scraper contacts the bottom of the conveyor belt. As the gas pressure inside the sealed chamber continuously increases, the third one-way valve is in the open state. The gas inside the sealed chamber enters the diversion chamber through the third one-way valve and is ejected through the jet holes. The ejected gas contacts the bottom of the conveyor belt and dries the cleaned conveyor belt, thereby improving the service life of the conveyor belt.

[0020] The beneficial effects of this invention are as follows: The scraper moves upward under air pressure, causing two first connecting blocks to slide inside two second sliding grooves. Simultaneously, it causes two first racks to move upward. Since one side of each first rack meshes with the outer edge of a transmission gear, the upward movement of the first racks causes the two transmission gears to rotate. At the same time, since one side of each second rack meshes with the outer edge of each first rack, the two second racks move downward, causing the second connecting blocks and the stabilizer to slide downward into the four first sliding grooves. During the downward movement of the stabilizer, two extrusion rollers are driven, causing the bottom of the two extrusion rollers to contact the bottom of the conveyor belt. Simultaneously, the two extrusion rollers remain perpendicular to the left and right sides of the scraper, thus stabilizing the bottom of the conveyor belt and improving the contact effect between the top of the conveyor belt and the scraper.

[0021] The beneficial effects of this invention are as follows: During the left-right movement of the two sealing rings, the two second transmission rods reciprocate left and right. One end of each second transmission rod slides inside the other two, while two third transmission rods are movably connected to one end of each of the two transmission rods. The other ends of each third transmission rod are non-centeredly connected to the front and rear sides of the roller brush. Thus, the two third transmission rods drive the roller brush to rotate, thereby cleaning the bottom of the conveyor belt. Because the annular tube is circular and the roller brush is located inside the annular tube, the bottom of the conveyor belt is rinsed through one end of the annular tube, then swept by the rotating roller brush, and finally rinsed a second time through the other end of the annular tube, thereby improving the dust cleaning effect on the bottom of the conveyor belt.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. 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.

[0044] Example 1

[0045] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 This is the first embodiment of the present invention, which provides an automatic pressurization adjustment device for a dust removal belt cleaner. The adjustment mechanism includes a conveying assembly 100, a transmission assembly 200, a drive assembly 300, a water injection assembly 400, a stabilizing assembly 500, an air injection assembly 600, a scraper assembly 700, and a water spray assembly 800. A scraper assembly 700 is fixedly installed at the bottom inside the conveying assembly 100. Air injection assemblies 600 are fixedly installed at the front and rear ends of one side of the scraper assembly 700. The front and rear ends of one end of the conveying assembly 100 are movable. A transmission assembly 200 is installed, and a drive assembly 300 is fixedly installed between the two transmission assemblies 200. One end of the drive assembly 300 is located inside the two air injection assemblies 600 respectively. A stabilizing assembly 500 is movably installed inside the conveying assembly 100 and on top of the scraper assembly 700. A water spraying assembly 800 is movably installed on the side of the conveying assembly 100 away from the scraper assembly 700. A water injection assembly 400 is fixedly installed on the front of the conveying assembly 100, and the top of the water injection assembly 400 is connected to the interior of the water spraying assembly 800.

[0046] During the conveying of coal slag by the conveying component 100, dust will adhere to the surface of the conveying component 100. The water injection component 400 is activated to inject water into the water spraying component 800 and spray it out to clean the dust at the bottom of the conveying component 100. As the conveying component 100 continues to rotate, it drives the transmission component 200 and the drive component 300. The drive component 300 pushes the air injection component 600 to inject air into the scraper component 700. The air continuously enters the scraper component 700, and the scraper component 700 moves upward under pressure. The top of the scraper component 700 contacts the bottom of the conveying component 100, thereby cleaning the water at the bottom of the conveying component 100 through the scraper component 700.

[0047] The drive component 300 pushes the air injection component 600 to rotate the water spray component 800. During the rotation of the water spray component 800, the bottom of the conveying component 100 is cleaned. At the same time, the water spray component 800 improves the dust removal effect on the surface of the conveying component 100. As the scraper component 700 moves upward, it drives the stabilizing component 500 to move downward and contact the bottom of the conveying component 100. The stabilizing component 500 improves the stability of the contact between the scraper component 700 and the conveying component 100, thereby improving the water cleaning effect of the scraper component 700 on the bottom of the conveying component 100.

[0048] The conveying assembly 100 includes a fixed frame 104. A first rotating roller 102 and a second rotating roller 103 are movably installed at the left and right ends inside the fixed frame 104, respectively. A conveyor belt 101 is sleeved on the outside of the first rotating roller 102 and the second rotating roller 103, respectively. A sewage pipe 105 is fixedly installed on the front of the fixed frame 104.

[0049] The first rotating roller 102 and the second rotating roller 103 are driven to rotate by the drive device, which in turn drives the conveyor belt 101 to rotate and transport the coal slag. The conveyor belt 101 is supported by the fixed frame 104. The drive device of the conveying assembly 100 is an existing technology and is omitted here.

[0050] The transmission assembly 200 includes a second transmission ring 203 fixedly installed at the front and rear ends of the second rotating roller 103. A transmission belt 201 is respectively sleeved on the outside of the two second transmission rings 203. A first transmission ring 202 is movably installed at the front and rear ends of the bottom of the fixed frame 104. The lower ends of the two transmission belts 201 are respectively sleeved on the outside of the two first transmission rings 202.

[0051] The drive assembly 300 includes a first connecting rod 301 fixedly installed between two first transmission rings 202. Fixing rings 302 are fixedly installed at the front and rear ends of the first connecting rod 301, and connecting rings 303 are movably sleeved on the outside of the two fixing rings 302. Second connecting rods 304 are fixedly installed on the outside of the two connecting rings 303.

[0052] During the rotation of the second rotating roller 103, the two second transmission rings 203 are driven to rotate, and the two second transmission rings 203 and the two first transmission rings 202 are driven to rotate. The rotation of the first transmission rings 202 drives the first connecting rod 301 to rotate. Since the front and rear sides of the first connecting rod 301 are not centered with the two first transmission rings 202, the rotation of the two first transmission rings 202 drives the first connecting rod 301 to rotate in a circle. During the rotation of the first connecting rod 301, the two fixed rings 302 and the two connecting rings 303 are driven to move, and the two second connecting rods 304 are pulled, causing the two second connecting rods 304 to move back and forth.

[0053] The gas injection assembly 600 includes a fixed plate 602 fixedly installed inside the fixed frame 104. Fixed cylinders 601 are fixedly installed at the front and rear ends of the fixed plate 602, respectively. Sealing rings 603 are movably sleeved inside the two fixed cylinders 601. First transmission rods 604 are fixedly installed on one side of the two sealing rings 603. One end of the two first transmission rods 604 is hinged to one end of the second connecting rod 304. Sealing plates 607 are fixedly installed at one end inside the two fixed cylinders 601, respectively. First one-way valves 606 are fixedly installed at the front and rear ends of the two sealing plates 607, respectively. Second one-way valves 605 are fixedly installed on the top of the two fixed cylinders 601, respectively. Second transmission rods 608 are fixedly installed on one side of the two first transmission rods 604, respectively.

[0054] Since one end of each of the two second connecting rods 304 is hinged to one end of each of the two first transmission rods 604, the two second connecting rods 304 push the two first transmission rods 604 to move back and forth. During the movement of the two first transmission rods 604, the two sealing rings 603 move. Since the outer diameter of the two sealing rings 603 is the same as the inner diameter of the two fixed cylinders 601, the gas inside the two fixed cylinders 601 is squeezed by the two sealing rings 603 moving to the left. During the process of the two sealing rings 603 squeezing the gas inside the two fixed cylinders 601, the four first one-way valves 606 are in the open state and the two second one-way valves 605 are in the closed state. Thus, the gas inside the two fixed cylinders 601 can be squeezed into the scraper assembly 700 through the two sealing rings 603.

[0055] At the same time, as the two sealing rings 603 move to the right, the four first one-way valves 606 are closed, while the two second one-way valves 605 are open. External gas enters the interior of the two fixed cylinders 601 through the two second one-way valves 605, and so on, through the reciprocating motion of the two sealing rings 603, the gas is continuously injected into the interior of the scraper assembly 700.

[0056] Example 2

[0057] Reference Figure 5 , Figure 7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0058] The scraper assembly 700 includes a sealing chamber 701 fixedly installed inside the bottom of the fixing frame 104. A scraper 702 is movably sleeved inside the sealing chamber 701. A diversion chamber 704 is opened at the bottom inside the scraper 702. Air jet holes 706 are equidistantly opened inside the scraper 702. The bottom of the air jet holes 706 is connected to the inside of the diversion chamber 704. A third one-way valve 705 is fixedly installed at the bottom of the diversion chamber 704. Springs 703 are fixedly installed at the left and right ends of the scraper 702.

[0059] The continuous and repeated movement of the two sealing rings 603 compresses the gas inside the two fixed cylinders 601 into the sealed chamber 701. The air pressure inside the sealed chamber 701 continuously increases, pushing the scraper 702 upward and compressing the two springs 703. The top of the scraper 702 contacts the bottom of the conveyor belt 101, and the top of the scraper 702 cleans the water at the bottom of the conveyor belt 101, preventing the conveyor belt 101 from polluting the ground with water. As the air pressure inside the sealed chamber 701 continues to increase, the third one-way valve 705 is in the open state. The gas inside the sealed chamber 701 enters the diversion chamber 704 through the third one-way valve 705 and is ejected through the jet holes 706. The ejected gas contacts the bottom of the conveyor belt 101 and dries the cleaned conveyor belt 101, thereby improving the service life of the conveyor belt 101.

[0060] Meanwhile, the top of scraper 702 is in contact with the bottom of conveyor belt 101 for a long time, thereby increasing the wear on the top of scraper 702. The gas inside the two fixed cylinders 601 is continuously injected into the sealing chamber 701 through the two sealing rings 603. Under the action of air pressure, scraper 702 is pushed upward, thereby avoiding the need for manual periodic adjustment due to severe wear of scraper 702, thus reducing labor costs. At the same time, it can ensure that the top of scraper 702 is always in contact with the bottom of conveyor belt 101.

[0061] Example 3

[0062] Reference Figure 3 , Figure 4 , Figure 5 , Figure 8 This is the third embodiment of the present invention, which is based on the above two embodiments.

[0063] The stabilizing component 500 includes a third connecting rod 501 movably installed inside the fixed frame 104. Transmission gears 502 are fixedly installed at the front and rear ends of the third connecting rod 501, and first connecting blocks 504 are fixedly installed at the front and rear ends of the scraper 702. First racks 503 are fixedly installed on one side of the two first connecting blocks 504, and one side of the two first racks 503 meshes with the outer edges of the two transmission gears 502. Second sliding grooves 510 are respectively opened on the front and rear sides of the fixed frame 104, and the two first connecting blocks 504 are movably sleeved inside the second sliding grooves 510.

[0064] The front and rear sides of the fixed frame 104 are respectively provided with four first sliding grooves 509. The interior of the four first sliding grooves 509 is movably fitted with second connecting blocks 506. The four second connecting blocks 506 are fixedly installed between the four second connecting blocks 506. The left side of the two second connecting blocks 506 is fixedly installed with a second rack 507. The two second racks 507 are meshed with the outer edge of the transmission gear 502. The left and right ends of the bottom of the fixed frame 505 are respectively movably installed with extrusion wheels 508.

[0065] Under air pressure, the scraper 702 moves upward, causing the two first connecting blocks 504 to slide inside the two second sliding grooves 510. Simultaneously, it causes the two first racks 503 to move upward. Since one side of each first rack 503 meshes with the outer edge of the transmission gear 502, the upward movement of the first racks 503 drives the two transmission gears 502 to rotate. At the same time, since one side of each second rack 507 meshes with the outer edge of each first rack 503, it causes the two second racks 507 to move downward, thus driving the second connecting block 506 and the stabilizer 505. The four second connecting blocks... The connecting blocks 506 slide downwards into the four first sliding grooves 509 respectively. During the downward movement of the stabilizer 505, the two extrusion rollers 508 are driven respectively, so that the bottom of the two extrusion rollers 508 contacts the bottom of the conveyor belt 101. At the same time, the two extrusion rollers 508 are perpendicular to the left and right sides of the scraper 702, thereby stabilizing the bottom of the conveyor belt 101 through the two extrusion rollers 508, making the contact effect between the top of the conveyor belt 101 and the scraper 702 better, and cleaning the washing water at the bottom of the conveyor belt 101 through the scraper 702, thereby improving the cleaning effect of the scraper 702 on the bottom of the conveyor belt 101.

[0066] Example 4

[0067] Reference Figure 3 , Figure 4 , Figure 9 This is the fourth embodiment of the present invention, which is based on the above three embodiments.

[0068] The water spray assembly 800 includes an annular tube 801 fixedly installed inside the fixing frame 104. The top of the annular tube 801 is provided with spray holes 802 at equal intervals. Stabilizing rings 805 are movably installed on the front and rear sides inside the fixing frame 104. Third transmission rods 804 are movably installed on one side of each of the two stabilizing rings 805. Roller brushes 803 are movably installed on one side of each of the two third transmission rods 804. The other ends of the two third transmission rods 804 are movably sleeved with one end of each of the two second transmission rods 608. Limiting grooves 806 are provided on the front and rear sides inside the fixing frame 104. One end of each of the two second transmission rods 608 is movably engaged inside the second transmission rod 608.

[0069] The water injection assembly 400 includes a receiving plate 401 fixedly installed on the front of the mounting bracket 104. A water pump 402 is fixedly installed on the top of the receiving plate 401. A connecting pipe 403 is fixedly installed on the front of the water pump 402. A connecting pipe 404 is fixedly installed on the top of the water pump 402. The top of the connecting pipe 404 is connected to the inside of the annular pipe 801.

[0070] By connecting the connector 403 to the water pipe, the water pump 402 is started to inject water into the interior of the annular pipe 801 through the connecting pipe 404, and the water is sprayed out through the nozzle 802. Since the annular pipe 801 is located at the bottom of the conveyor belt 101, the water sprayed out through the nozzle 802 washes away the dust attached to the bottom of the conveyor belt 101.

[0071] Simultaneously, as the two sealing rings 603 move left and right, they drive the two second transmission rods 608 to reciprocate left and right. One end of the two second transmission rods 608 slides inside the two limiting grooves 806, while the two third transmission rods 804 are movably connected to one end of the two limiting grooves 806. The other end of the two limiting grooves 806 is connected to the front and rear sides of the roller brush 803 in a non-circular manner. Thus, the two third transmission rods 804 push the roller brush 803 to rotate, thereby cleaning the bottom of the conveyor belt 101 through the two roller brushes 803. Since the annular tube 801 is annular and the roller brush 803 is located inside the annular tube 801, the bottom of the conveyor belt 101 is rinsed through one end of the annular tube 801. The rinse water falls into the fixed frame 104 and is discharged through the drain pipe 105. The bottom of the conveyor belt 101 is then swept by the rotation of the roller brush 803, and the bottom of the conveyor belt 101 is rinsed a second time through the other end of the annular tube 801, thereby improving the dust cleaning effect of the bottom of the conveyor belt 101.
