Description
Technical Field
[0001] This disclosure relates to the field of loading and unloading equipment technology, specifically to a material receiving device and a stacker-reclaimer. Background Technology
[0002] A stacker-reclaimer is a high-efficiency loading and unloading machine that can both stack and reclaim materials. It is mainly used for loading and unloading bulk materials such as coal and ore in large dry bulk cargo yards, such as docks, steel mills, thermal power plants, and mines. Stacker-reclaimers have two operating modes: stacking and reclaiming. In stacking, bulk materials are transported by a belt conveyor close to the ground, unloaded onto a belt conveyor on the boom via a tail car, and then dumped from the boom's front end into the stockyard. Through the operation of the entire machine, the boom's rotation and pitching can shape the stockpile into a neat trapezoidal cross-section. Reclaiming is achieved continuously through boom rotation and bucket wheel rotation. Material is unloaded via a discharge plate onto a belt conveyor on the boom running in the opposite direction, and then conveyed to a belt conveyor near the ground for removal. Through the operation of the entire machine, the boom's rotation and pitching can completely remove material from the stockpile.
[0003] In related technologies, during the operation of stacker-reclaimers, especially during material reclaiming operations, when conveying materials such as coal, coal is conveyed from the boom belt conveyor to the yard belt conveyor near the ground. Some coal ash and lighter coal particles float in the air, causing waste of resources and environmental pollution. Summary of the Invention

[0019] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0020] In this disclosure, for ease of description, a first direction, a second direction, and a third direction are defined for the receiving device, where "X" represents the first direction, "Y" represents the second direction, and "X" represents the third direction, wherein the first direction, the second direction, and the third direction are mutually perpendicular. Specifically, for example... Figure 1 In the diagrams shown, the third direction Z represents the vertical direction, the second direction Y represents the inward / outward direction within the paper, and the first direction X represents the horizontal direction. Unless otherwise stated, "inward" and "outward" refer to the interior and exterior of the corresponding component's outline; "far" and "near" refer to the spatial distance of the corresponding component relative to another component. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not imply sequentiality or importance. When the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0021] The material receiving device and stacker-reclaimer in the exemplary embodiments of this disclosure will now be described with reference to the accompanying drawings.
[0022] According to the first aspect of this disclosure, referring to Figures 1 to 10 This disclosure provides a material receiving device, including a substrate 2, a collecting mechanism 3, and a cleaning mechanism 4. The collecting mechanism 3 is connected to the substrate 2 and includes a first driving component 31 and an electrostatic dust removal plate 32. The first driving component 31 is used to drive the electrostatic dust removal plate 32 so that the electrostatic dust removal plate 32 switches between a working position and a cleaning position. In the working position, the electrostatic dust removal plate 32 faces the receiving area of the downstream conveyor 1 for receiving material to adsorb particulate matter. The cleaning mechanism 4 includes a cleaning component 41 and a storage component 42. The cleaning component 41 includes a scraper 43 for scraping off particulate matter from the surface of the electrostatic dust removal plate 32 located in the cleaning position. The storage component 42 is used to receive particulate matter from the surface of the electrostatic dust removal plate 32.
[0023] The above technical solution enables the collection and storage of airborne particles. The electrostatic precipitator plate 32 can be in either a working or clean position. Specifically, when in the working position, the electrostatic precipitator plate 32 can adsorb and collect airborne particles from the receiving area of the downstream conveyor 1. Then, the first drive assembly 31 can drive the electrostatic precipitator plate 32 to switch from the working position to the clean position. Under the action of the scraper 43, the particles on the surface of the electrostatic precipitator plate 32 are scraped off and stored in the storage unit 42. Thus, under the action of the receiving device, it is convenient to carry out subsequent centralized processing or recycling of airborne particles, so as to save resources and protect the environment.
[0024] In one exemplary application scenario, a material collection device can be installed on a stacker-reclaimer. During material collection operations, materials are transported from the stacker-reclaimer's boom conveyor to a ground-level yard conveyor. These materials can be, for example, coal or ore. During transport, some coal ash and lighter coal particles may become airborne in the receiving area of the yard conveyor. These airborne particles can be collected and stored using electrostatic precipitators 32, reducing resource waste and environmental pollution. It is understood that these particles include, but are not limited to, material particles, as well as impurities, dust, or other particulate matter mixed in with the material. Collecting these particles together with the material collection device facilitates subsequent centralized processing and recycling, thereby saving resources and protecting the environment.
[0025] In some embodiments, refer to Figure 2The electrostatic precipitator plates 32 can be in two sets. The collection mechanism 3 is configured such that when one set of electrostatic precipitator plates 32 is in the working position, the other is in the clean position. In this way, particulate matter can be adsorbed and collected almost continuously. The particulate matter adsorbed on the surface of the electrostatic precipitator plate 32 in the clean position can be scraped off by the scraper 43 and then stored in the storage unit 42. When the cleaning is completed or the adsorption effect of the electrostatic precipitator plate 32 in the working position is reduced due to excessive particulate matter on the surface, the two sets of electrostatic precipitator plates 32 switch between the working position and the clean position. Thus, the two sets of electrostatic precipitator plates 32 can alternately perform the adsorption and collection of particulate matter to achieve non-stop material conveying and improve the efficiency of stacking and reclaiming.
[0026] In some embodiments, refer to Figure 1 and Figure 3 The collection mechanism 3 further includes a second drive assembly 33, which may include a rotating shaft 331 rotatably connected to the substrate 2 about its own axis and a second drive member 332 drivenly connected to the rotating shaft 331. The rotating shaft 331 extends along a first direction, and the two sets of electrostatic dust removal plates 32 are each movably connected to the rotating shaft 331 along the first direction via the first drive assembly 31. In this way, the two sets of electrostatic dust removal plates 32 can each be connected to the rotating shaft 331 via the first drive assembly 31, and the first drive assembly 31 can drive the corresponding set of electrostatic dust removal plates 32 to move along the first direction to switch between a working position and a cleaning position. In addition, the two electrostatic dust removal plates 32 can be respectively connected to opposite sides of the rotating shaft 331 about its own axis. That is, the electrostatic dust removal plate 32 in the working position and the electrostatic dust removal plate 32 in the cleaning position are spaced apart on both sides of the rotating shaft 331 along the second direction. As a result, the cleaning mechanism 4 can obtain a larger installation and operating space to facilitate cleaning of the electrostatic dust removal plate 32 in the cleaning position. The second driving element 332 can be constructed in any suitable manner. For example, the second driving element 332 may include a second motor, the output shaft of which drives the rotating shaft 331 to rotate around its own axis, thereby changing the position of the electrostatic precipitator plate 32 in the second direction. This disclosure does not impose any specific limitations on this.
[0027] It is understandable that the first drive component 31 can be constructed in any suitable manner, as shown in the reference. Figure 3A receiving space is formed on the rotating shaft 331 for mounting the first drive assembly 31. The first drive assembly 31 may include a drive motor 311, a drive screw 312, and a drive nut 313. The drive screw 312 extends along a first direction. The drive motor 311 is driven and connected to the drive screw 312. The drive nut 313 is threadedly connected to the drive screw 312. A corresponding electrostatic dust removal plate 32 is connected to the drive nut 313. Thus, the drive motor 311 drives the drive screw 312 to rotate, thereby driving the nut 313 to move along the extension direction of the drive screw 312 to switch the electrostatic dust removal plate 32 between a working position and a cleaning position. Furthermore, in some other possible variations not shown in the figures, the first drive assembly 31 may include a cylinder or a hydraulic cylinder, etc. The corresponding electrostatic dust removal plate 32 is connected to the piston rod of the cylinder or hydraulic cylinder. Similarly, the cylinder or hydraulic cylinder can drive the electrostatic dust removal plate 32 to move along the first direction to switch between a working position and a cleaning position. This disclosure does not specifically limit this aspect.
[0028] In some embodiments, refer to Figure 2 and Figure 7 The storage unit 42 may include a transfer box 421 and a storage box 422. The transfer box 421 has an opening, and the electrostatic dust removal plate 32 in the clean position can cover the opening of the transfer box 421 or be at least partially accommodated in the transfer box 421 through the opening. The scraper 43 is located in the transfer box 421. In this way, the surface of the electrostatic dust removal plate 32 in the clean position that has adsorbed particulate matter is placed in the transfer box 421 so that it can be scraped by the scraper 43 and leaked as little as possible to be temporarily stored in the transfer box 421. Specifically, the first drive assembly 31 can drive a corresponding set of electrostatic dust removal plates 32 to move from the working position to the cleaning position along the first direction until the electrostatic dust removal plates 32 are located between the substrate 2 and the transfer box 421. During this process, the second drive component 332 can synchronously drive the connecting rotating shaft 331 to rotate around its own axis to avoid the cleaning mechanism 4, thereby changing the position of the electrostatic dust removal plates 32 in the second direction. Then, the first drive assembly 31 drives the electrostatic dust removal plates 32 to move again to cover the opening of the transfer box 421 or to be at least partially contained in the transfer box 421 through the opening to reach the cleaning position. In addition, there is a connecting pipe 423 between the transfer box 421 and the storage box 422, so that the particulate matter temporarily stored in the transfer box 421 is stored in the storage box 422 through the connecting pipe 423. The connecting pipe 423 is inclined to facilitate the transport and flow of particulate matter. It is understood that, in some other possible variations not shown in the attached drawings, the bottom inner wall of the transfer box 421 may also be inclined to allow as much particulate matter as possible to be transported and flowed into the storage box 422, thereby improving the recycling rate of particulate matter.
[0029] In some embodiments, refer to Figure 2 and Figure 7 The top of the storage box 422 is provided with a through hole communicating with the connecting pipe 423. The storage component 42 may also include a collection hopper 424. The collection hopper 424 is movably disposed in the storage box 422 via the transmission mechanism 6. The collection hopper 424 has an upward-facing inlet. The cleaning component 41 includes a drive structure 44 for driving the scraper 43 to move. The drive structure 44 is selectively connected to or disconnected from the transmission mechanism 6 so that the collection hopper 424 can be driven to move via the transmission mechanism 6. In this way, the particulate matter temporarily stored in the transfer box 421 is conveyed through the connecting pipe 423 and passes through the through hole to fall into the collection hopper 424 from the feed port. During this process, the drive structure 44 drives the scraper 43 to move to scrape off the particulate matter adsorbed on the surface of the electrostatic dust removal plate 32. At the same time, the drive structure 44 is connected to the transmission mechanism 6 to drive the collection hopper 424 to move. For example, the collection hopper 424 can move linearly along the second direction. Thus, the position of the storage box 422 and the through hole at the top does not change. The movement of the collection hopper 424 causes the particulate matter to fall from the through hole through the feed port to different positions at the bottom of the collection hopper 424, so as to achieve uniform storage of particulate matter in the collection hopper 424. In addition, the collection hopper 424 may have a connection port for connecting to an external pipeline, so that the particulate matter in the collection hopper 424 can be discharged through the connection port to the external pipeline.
[0030] In some embodiments, refer to Figure 2 , Figure 4 and Figure 5The scraper 43 may include a first scraper 431 and a second scraper 432. The drive structure 44 includes a third drive assembly 441 for driving the first scraper 431 to move horizontally and a fourth drive assembly 442 for driving the second scraper 432 to move vertically. The horizontal direction can refer to a second direction, and the vertical direction can refer to a third direction. Thus, the third drive assembly 441 drives the first scraper 431 to move horizontally to scrape off particles adsorbed on the surface of the electrostatic precipitator plate 32, and the fourth drive assembly 442 drives the second scraper 432 to move vertically to scrape off particles attached to the surface of the electrostatic precipitator plate 32 and the surface of the first scraper 431. This achieves the goal of transporting as much of the attached particles as possible into the storage tank 422, thereby improving the recycling rate of the particles. Furthermore, the third drive assembly 441 and the fourth drive assembly 442 can be connected to or separated from the transmission mechanism 6, so that the movement of the first scraper 431 and the second scraper 432 does not affect each other and does not affect the scraping of particles. That is, when the third drive assembly 441 drives the first scraper 431 to move in the horizontal direction, the third drive assembly 441 is connected to the transmission mechanism 6 and drives the collection hopper 424 to move through the transmission mechanism 6. At this time, the fourth drive assembly 442 is separated from the transmission mechanism 6. When the fourth drive assembly 442 drives the second scraper 432 to move in the vertical direction, the fourth drive assembly 442 is connected to the transmission mechanism 6 and drives the collection hopper 424 to move through the transmission mechanism 6. At this time, the third drive assembly 441 is separated from the transmission mechanism 6.
[0031] In some embodiments, refer to Figure 2 , Figures 3 to 7The transmission mechanism 6 may include a first lead screw 61 disposed in the storage box 422, a first lead screw nut 62 threadedly connected to the first lead screw 61, and a first transmission wheel 63 coaxially connected to the first lead screw 61. The first lead screw nut 62 is connected to the collection hopper 424. The first lead screw 61 extends along a second direction. Thus, the rotation of the first lead screw 61 can drive the first lead screw nut 62 to move along the extension direction of the first lead screw 61, thereby driving the collection hopper 424 to move. In addition, the transmission mechanism 6 also includes a first housing 64, a transmission shaft 65 rotatably mounted on the first housing 64 about its own axis, and a second transmission wheel 66, a third transmission wheel 67, and a fourth transmission wheel 68 respectively sleeved on the transmission shaft 65. The second transmission wheel 66 and the third transmission wheel 67 are each unclampedly connected to the transmission shaft 65 through a locking structure 7 so as to selectively rotate synchronously with the transmission shaft 65. The second transmission wheel 66 is connected to the third drive assembly 441, the third transmission wheel 67 is connected to the fourth drive assembly 442, and the fourth transmission wheel 68 is fixed to the transmission shaft 65 and connected to the first transmission wheel 63 through a first synchronous belt 69. Thus, when the third drive assembly 441 drives the first scraper 431 to move horizontally, the second drive wheel 66 is connected to the drive shaft 65 through the locking structure 7. As a result, the third drive assembly 441 drives the drive shaft 65 to rotate through the second drive wheel 66, and the fourth drive wheel 68 rotates synchronously and drives the first drive wheel 63 to rotate through the first synchronous belt 69, which in turn drives the first lead screw 61 to rotate, so that the first lead screw nut 62 moves along the extension direction of the first lead screw 61 to drive the collection hopper 424 to move. At this time, the third drive wheel 67 is disengaged from the drive shaft 65 through the locking structure 7. Similarly, when the fourth drive assembly 442 drives the second scraper 432 to move vertically, the third transmission wheel 67 is connected to the transmission shaft 65 through the locking structure 7. Thus, the fourth drive assembly 442 drives the transmission shaft 65 to rotate through the third transmission wheel 67, and the fourth transmission wheel 68 rotates synchronously and drives the first transmission wheel 63 to rotate through the first synchronous belt 69, thereby driving the first lead screw 61 to rotate, so that the first lead screw nut 62 moves along the extension direction of the first lead screw 61 to drive the collection hopper 424 to move. At this time, the second transmission wheel 66 is disengaged from the transmission shaft 65 through the locking structure 7.
[0032] In some embodiments, refer to Figure 2 , Figures 3 to 7The cleaning mechanism 4 includes a second housing 45 connected to the transfer box 421. The third drive assembly 441 can be constructed in any suitable manner. For example, the third drive assembly 441 is connected to the first housing 64 and may include a third motor 4411, a third lead screw 4412, a third lead screw nut 4413, a third connecting rod 4414, and a fifth transmission wheel 4415. The third lead screw 4412 extends along a second direction. The third motor 4411 is driven by the third lead screw 4412. The third lead screw nut 4413 is threaded to the third lead screw 4412 so as to reciprocate in the horizontal direction as the third lead screw 4412 rotates. One end of the third connecting rod 4414 is connected to the third lead screw nut 4413, and the other end passes through the transfer box 421 and is connected to the first scraper 431. The fifth transmission wheel 4415 is coaxially connected to the third lead screw 4412 and is connected to the second transmission wheel 66 via a second synchronous belt 4416. In this way, the third motor 4411 drives the third lead screw 4412 to rotate, thereby driving the third lead screw nut 4413 to move horizontally, and through the third connecting rod 4414, drives the first scraper 431 to move horizontally, so as to scrape off the particulate matter adsorbed on the surface of the electrostatic dust removal plate 32. During this process, the rotation of the third lead screw 4412 drives the fifth transmission wheel 4415 to rotate synchronously, thereby driving the second transmission wheel 66 to rotate through the second synchronous belt 4416, thereby driving the transmission shaft 65 to rotate. The fourth transmission wheel 68 rotates synchronously and drives the first transmission wheel 63 to rotate through the first synchronous belt 69, which in turn drives the first lead screw 61 to rotate, so that the first lead screw nut 62 moves along the extension direction of the first lead screw 61 to drive the collection hopper 424 to move.
[0033] It is understood that the first transmission wheel 63, the second transmission wheel 66, the fourth transmission wheel 68, and the fifth transmission wheel 4415 can be constructed in any suitable manner. For example, the first transmission wheel 63 and the fourth transmission wheel 68, the second transmission wheel 66 and the fifth transmission wheel 4415 can be constructed as pulleys or sprockets in pairs. Correspondingly, the first synchronous belt 69 and the second synchronous belt 4416 can be constructed as transmission belts or transmission sprockets. Exemplarily, the first transmission wheel 63, the second transmission wheel 66, the fourth transmission wheel 68, and the fifth transmission wheel 4415 can all be constructed as pulleys, and correspondingly, the first synchronous belt 69 and the second synchronous belt 4416 can be constructed as transmission belts. This disclosure does not impose specific limitations in this regard.
[0034] In some embodiments, refer to Figure 2 , Figures 3 to 7The cleaning mechanism 4 also includes a third housing 46 connected between the transfer box 421 and the first housing 64. The fourth drive assembly 442 can be constructed in any suitable manner. For example, the fourth drive assembly 442 may include a fourth motor 4421, a fourth lead screw 4422, a fourth lead screw nut 4423, a fourth connecting rod 4424, and a sixth transmission wheel 4425. The fourth motor 4421 is driven to the fourth lead screw 4422. The fourth lead screw nut 4423 is threaded to the fourth lead screw 4422 so as to reciprocate in the vertical direction as the fourth lead screw 4422 rotates. One end of the fourth connecting rod 4424 is connected to the fourth lead screw nut 4423, and the other end passes through the transfer box 421 and is connected to the second scraper 432. The sixth transmission wheel 4425 is engaged with the third transmission wheel 67. Thus, the fourth motor 4421 drives the fourth lead screw 4422 to rotate, thereby moving the fourth lead screw nut 4423 vertically. This, in turn, drives the second scraper 432 vertically via the fourth connecting rod 4424, scraping away particles adhering to the surfaces of the electrostatic precipitator plate 32 and the first scraper 431. During this process, the rotation of the fourth lead screw 4422 drives the sixth transmission wheel 4425 to rotate synchronously. The sixth transmission wheel 4425, through meshing connection, drives the third transmission wheel 67 to rotate, thereby driving the transmission shaft 65 to rotate. The fourth transmission wheel 68 rotates synchronously and, through the first synchronous belt 69, drives the first transmission wheel 63 to rotate, which in turn drives the first lead screw 61 to rotate. This causes the first lead screw nut 62 to move along the extension direction of the first lead screw 61, thereby moving the collection hopper 424. The second transmission wheel 66 and the sixth transmission wheel 4425 can be constructed as meshing bevel gears.
[0035] In some embodiments, refer to Figure 8 and Figure 9 The locking structure 7 includes a mounting groove 71 within the drive shaft 65, a locking member 72 movably disposed within the mounting groove 71, and a driving part 73 for driving the locking member 72 to move. The locking member 72 is selectively inserted into a locking groove 74 on the second drive wheel 66 or the third drive wheel 67. Thus, under the action of the driving part 73, the locking member 72 can selectively insert into the locking groove 74 on the second drive wheel 66 or the third drive wheel 67 to connect the second drive wheel 66 or the third drive wheel 67 to the drive shaft 65, or the locking member 72 can disengage from the locking groove 74 on the second drive wheel 66 or the third drive wheel 67 to disengage the second drive wheel 66 or the third drive wheel 67 from the drive shaft 65. The locking member 72 may include a movable block slidably connected in the mounting groove 71 and a locking block for inserting into the mounting groove 71. Thus, the driving unit 73 can drive the movable block to slide in the mounting groove 71, thereby moving the locking block and inserting it into or disengaging it from the locking groove 74, so as to realize the connection or disengagement of the second transmission wheel 66 or the third transmission wheel 67 from the transmission shaft 65.
[0036] It is understood that the drive unit 73 can be constructed in any suitable manner to drive the locking member 72 to move. For example, the drive unit 73 may include a first electromagnet 731 connected to the side of the locking member 72 near the bottom of the mounting groove 71, and a second electromagnet 732 connected to the inner wall of the bottom of the mounting groove 71 and engaged with the first electromagnet 731 in a repulsive manner. At the same time, a return spring 733 is connected between the side of the locking member 72 near the locking groove 74 and the inner wall of the top of the mounting groove 71. Thus, the first electromagnet 731 and the second electromagnet 732 are energized to drive the locking member 72 toward the locking groove 74 through repulsion until it is inserted into the locking groove 74, thereby realizing the connection between the second drive wheel 66 or the third drive wheel 67 and the drive shaft 65. Alternatively, by de-energizing the first electromagnet 731 and the second electromagnet 732, the locking member 72 moves away from the locking groove 74 under the pushing force of the return spring 733 until it disengages from the locking groove 74, thereby disengaging the second transmission wheel 66 or the third transmission wheel 67 from the transmission shaft 65. The return spring 733 can also be connected between the side of the locking member 72 near the bottom of the mounting groove 71 and the inner wall of the bottom of the mounting groove 71. In this case, the return spring 733 provides a pulling force to move the locking member 72 until it disengages from the locking groove 74. This disclosure does not specifically limit this aspect.
[0037] In some embodiments, refer to Figure 1 , Figure 2 and Figure 10 The cleaning mechanism 4 is movably connected to the base plate 2 along the first direction via the fifth drive assembly 5, so that the transfer box 421 can be opened and positioned on the electrostatic dust removal plate 32 located in the cleaning position. In this way, the fifth drive assembly 5 can drive the cleaning mechanism 4 to move and adaptively adjust the position of the transfer box 421 to clean the electrostatic dust removal plate 32. The switching of the position of the electrostatic dust removal plate 32 and the adjustment of the position of the transfer box 421 can be carried out simultaneously, improving work efficiency. It is understood that the fifth drive assembly 5 can be constructed in any suitable manner. For example, the fifth drive assembly 5 may include a fifth housing 51 connected to the substrate 2, and a fifth motor 52, a fifth lead screw 53, and a fifth lead screw nut 54 connected to the fifth housing 51. The fifth lead screw 53 extends along a first direction, the fifth motor 52 is drivenly connected to the fifth lead screw 53, the fifth lead screw nut 54 is threadedly connected to the fifth lead screw 53, and the first housing 64 is connected to the fifth lead screw nut 54. Thus, the fifth motor 52 drives the fifth lead screw 53 to rotate, thereby moving the fifth lead screw nut 54 along the first direction, which in turn moves the cleaning mechanism 4 via the first housing 64, changing the position of the transfer box 421. Furthermore, in some other possible embodiments not shown in the accompanying drawings, the fifth drive assembly 5 may also include a hydraulic cylinder or a pneumatic cylinder, the piston rod of which is connected to the drive shaft 65 and can drive the drive shaft 65 to reciprocate along the first direction. This disclosure does not specifically limit this aspect.
[0038] According to a second aspect of this disclosure, a stacker-reclaimer is provided, comprising a yard belt conveyor and the aforementioned material collection devices. The downstream conveyor 1 is a yard belt conveyor that can receive materials conveyed from an upstream boom belt conveyor 11. The number of material collection devices is at least two sets, respectively arranged on opposite sides of the downstream conveyor 1. Thus, by using multiple sets of material collection devices, more thorough adsorption and collection of airborne particulate matter can be achieved, improving resource recycling rates and protecting the environment. The multiple sets of material collection devices can be distributed at intervals along a first direction on both sides of the downstream conveyor 1, or they can be arranged sequentially on the same side of the downstream conveyor 1 along a second direction; this disclosure does not specifically limit the arrangement.
[0039] This disclosure exemplarily illustrates the operation of the material handling device.
[0040] When one of the two sets of electrostatic precipitator plates 32 is in the working position, the other is in the clean position. In the working position, the electrostatic precipitator plate 32 faces the receiving area of the downstream conveyor 1 for adsorbing particulate matter. When the adsorption effect of the electrostatic precipitator plate 32 in the working position is reduced due to excessive particulate matter on the surface, the two sets of electrostatic precipitator plates 32 switch between the working position and the clean position.
[0041] The drive motor 311 drives the drive screw 312 to rotate, which in turn drives the screw nut 313 to move along the extension direction of the drive screw 312 to move the electrostatic dust removal plate 32. The second drive member 332 can synchronously drive the connected rotating shaft 331 to rotate around its own axis so as to avoid the cleaning mechanism 4 and change the position of the electrostatic dust removal plate 32 in the second direction. The fifth motor 52 drives the fifth screw 53 to rotate so as to move the fifth screw nut 54 along the first direction, so as to drive the cleaning mechanism 4 to move through the first housing 64 and change the position of the transfer box 421, so that the electrostatic dust removal plate 32 is installed in the opening of the transfer box 421 or the electrostatic dust removal plate 32 is at least partially accommodated in the transfer box 421 through the opening. At this time, the electrostatic dust removal plate 32 is in the clean position.
[0042] The third motor 4411 drives the third lead screw 4412 to rotate, thereby moving the third lead screw nut 4413 horizontally. This, in turn, moves the first scraper 431 horizontally via the third connecting rod 4414, scraping away particles adsorbed on the surface of the electrostatic dust removal plate 32. During this process, the first electromagnet 731 and the second electromagnet 732 are energized, causing the locking member 72 to move towards the locking groove 74 through repulsion until it is inserted into the locking groove 74, thus connecting the second transmission wheel 66 to the transmission shaft 65. Simultaneously, the first electromagnet 731 and the second electromagnet 732 are de-energized, and the return spring... Under the thrust of 733, the locking member 72 moves away from the locking groove 74 until it disengages from the locking groove 74, thereby disengaging the third transmission wheel 67 from the transmission shaft 65. The rotation of the third lead screw 4412 drives the fifth transmission wheel 4415 to rotate synchronously, thereby driving the second transmission wheel 66 to rotate via the second synchronous belt 4416. This drives the transmission shaft 65 to rotate, and the fourth transmission wheel 68 rotates synchronously and drives the first transmission wheel 63 to rotate via the first synchronous belt 69. This drives the first lead screw 61 to rotate, causing the first lead screw nut 62 to move along the extension direction of the first lead screw 61 to move the collection hopper 424.
[0043] Then, the fourth motor 4421 drives the fourth lead screw 4422 to rotate, thereby moving the fourth lead screw nut 4423 vertically. This, in turn, drives the second scraper 432 vertically via the fourth connecting rod 4424, to scrape off the particles attached to the surface of the electrostatic dust removal plate 32 and the surface of the first scraper 431. During this process, the first electromagnet 731 and the second electromagnet 732 are energized, and through repulsion, the locking member 72 moves toward the locking groove 74 until it is inserted into the locking groove 74, thus connecting the third transmission wheel 67 to the transmission shaft 65. Simultaneously, the first electromagnet 731 and the second electromagnet 732... When the power is cut off, under the pushing force of the return spring 733, the locking member 72 moves away from the locking groove 74 until it disengages from the locking groove 74, thereby disengaging the second transmission wheel 66 from the transmission shaft 65. The rotation of the four lead screws drives the sixth transmission wheel 4425 to rotate synchronously. The sixth transmission wheel 4425 drives the third transmission wheel 67 to rotate through meshing connection, thereby driving the transmission shaft 65 to rotate. The fourth transmission wheel 68 rotates synchronously and drives the first transmission wheel 63 to rotate through the first synchronous belt 69, thereby driving the first lead screw 61 to rotate, so that the first lead screw nut 62 moves along the extension direction of the first lead screw 61 to drive the collection hopper 424 to move.
