DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, they can also be understood as further technical solutions without creative work. In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0020] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, proposes a pulse dust removal device for rust removal, including a casing 1, the casing 1 has a accommodating space 11, and the accommodating space has a replacement port; a mounting plate 2 is arranged in the accommodating space 11, and the mounting plate 2 has a plurality of exhaust holes 21; there are a plurality of filter cartridges 3, and a plurality of filter cartridges 3 are circulated and transported and arranged on the mounting plate 2, and a plurality of filter cartridges 3 are arranged at intervals. After the filter cartridges 3 are connected to the exhaust holes 21, they are used for dust removal and cleaning, and the replacement port is used for replacing the filter cartridges.

[0023] In this embodiment, the housing 1 has a storage space 11, which provides external protection and internal space support for the entire dust removal device. The mounting plate 2 is fixedly arranged in the storage space 11 of the housing 1, and has a plurality of exhaust holes 21 to discharge the filtered gas. There are a plurality of filter cartridges 3, which are arranged on the mounting plate 2 in a circular conveying manner and are spaced apart from each other to ensure that each filter cartridge 3 can be effectively connected with the exhaust hole 21 to form a complete dust removal and cleaning channel. During actual operation, the gas mixed with rust enters the lower layer of the storage space 11 from a specific air inlet of the housing 1. In the lower space, the gas first contacts the filter cartridge 3, and impurities such as rust are blocked and retained by the filter cartridge 3. The clean gas after filtration passes through the filter cartridge 3 and the exhaust hole 21 into the upper layer of the storage space 11, completing the preliminary dust removal process.

[0024] The filter cartridge 3 arranged in a circulation manner facilitates disassembly and maintenance. During the circulation of the filter cartridge 3, the filter cartridge 3 moves to the replacement port in sequence, and any filter cartridge 3 can be replaced through the replacement port. The filter cartridge 3 can be fixed on the mounting plate 2 by threads, but is not limited to threads. Compared with the prior art, the inconvenience of disassembly of the traditional filter cartridge 3 is overcome. When an internal filter cartridge 3 is damaged, it can be replaced separately without first disassembling the outer filter cartridge 3, which greatly reduces the maintenance cost and difficulty, and improves the availability and maintenance efficiency of the equipment.

[0025] Furthermore, it also includes a driving wheel 4, which is rotatably arranged on the mounting plate 2; a driven wheel 5 is rotatably arranged on the mounting plate 2; a synchronous belt 6 is wound around the driving wheel 4 and the driven wheel 5, and a plurality of filter cartridges 3 are arranged on the synchronous belt 6 at intervals.

[0026] In this embodiment, the driving wheel 4 is rotatably mounted on the mounting plate 2 through a suitable bearing structure to ensure that it can rotate and is connected to an external power source (such as a motor) to obtain rotational power. The driven wheel 5 is also rotatably mounted on the mounting plate 2 to cooperate with the transmission of the synchronous belt 6. The synchronous belt 6 surrounds the driving wheel 4 and the driven wheel 5 to form a closed transmission loop. A plurality of filter cartridges 3 are spaced and firmly mounted on the synchronous belt 6 through specific connectors, so that the filter cartridges 3 can achieve cyclic movement with the operation of the synchronous belt 6.

[0027] The combination of the driving wheel 4, the driven wheel 5 and the synchronous belt 6 realizes the automatic circulation and transportation of the filter cartridge 3, thereby improving the automation degree and operation efficiency of the equipment. This structural design makes the replacement and maintenance of the filter cartridge 3 more convenient. The operator can pause the equipment as needed during the operation of the equipment and directly operate the filter cartridge 3 at a specific position, further improving the convenience of equipment maintenance.

[0028] Furthermore, it also includes a mounting block 7, the mounting block 7 has a connecting portion 71 and a mounting portion 72, the connecting portion 71 is arranged on the mounting plate 2, and the mounting portion 72 has an annular tooth 721; the first mounting member 8 is arranged on the synchronous belt 6, the first mounting member 8 has a first through cavity 81, and the first through cavity 81 is used to communicate with the exhaust hole 21; the second mounting member 9 is rotatably arranged on the first mounting member 8, and is sleeved outside the first mounting member 8, the second mounting member 9 has a second through cavity 91, and the second through cavity 91 is communicated with the first through cavity 81; the gear 10 is arranged on the second mounting member 9, the gear 10 is meshed with the annular tooth 721, the filter cartridge 3 is arranged on the second mounting member 9, and the filter cartridge 3 is circulated and transported in the accommodating space 11 through the second mounting member 9.

[0029] In this embodiment, the connection portion 71 of the mounting block 7 is arranged on the mounting plate 2 by welding, bolt connection or other fixing methods, and the annular teeth 721 of the mounting portion 72 is meshed with the gear 10. The first mounting member 8 is fixedly mounted on the synchronous belt 6, and the first through cavity 81 inside it can be aligned with the exhaust hole 21 on the mounting plate 2 to ensure gas circulation. The second mounting member 9 is rotatably mounted on the outside of the first through cavity 81 through a suitable bearing structure, and the second through cavity 91 inside it is connected with the first through cavity 81 to ensure that the transmission of gas between the two is not hindered. The gear 10 is fixedly mounted on the second mounting member 9 and tightly meshed with the annular teeth 721 of the mounting block 7. The filter cartridge 3 is fixedly mounted on the second mounting member 9. In the process of the synchronous belt 6 driving the filter cartridge 3 to move, due to the meshing action of the gear 10 and the annular teeth 721, the filter cartridge 3 will slowly rotate along its own axis. The installation direction of the filter cartridge 3 can be designed to be a structure opposite to the rotation direction of the filter cartridge 3, or the filter cartridge 3 can be directly clamped on the second mounting member 9. Since the filter cartridge 3 can also rotate on its own, during the operation of the filter cartridge 3, the operator can observe the conditions of each filter cartridge 3 through the replacement port. If the filter cartridge 3 is agglomerated or broken, the machine can be stopped for replacement.

[0030] The meshing design of the gear 10 and the annular teeth 721 enables the filter cartridge 3 to rotate automatically during the cyclic movement, preventing the dust on the adjacent filter cartridge 3 from splashing onto the same position of other filter cartridges 3 during dust cleaning. In this embodiment, there are at most two rows of filter cartridges 3, and a portion of the filter cartridges 3 after rotation is always away from other filter cartridges 3.

[0031] The operator can visually observe the rotation of the filter cartridge 3 and the adhesion status of the dust on the surface through the transparent observation port on the casing 1, which corresponds to the replacement port, and promptly discover whether the filter cartridge 3 has problems such as damage or abnormal dust adhesion, so as to take maintenance measures in time and ensure the stable operation of the equipment.

[0032] Furthermore, an installation space 722 is formed between the installation portion 72 and the installation plate 2, the synchronous belt 6 is arranged in the installation space 722 for cyclic transmission, and the driving wheel 4 and the driven wheel 5 are rotatably arranged in the installation space 722. The installation portion 72 has a through hole 723, which is connected to the installation space 722, and also includes a rotating member 110, which passes through the through hole 723 and is arranged on the driving wheel 4 and / or the driven wheel 5; there are a plurality of baffles 120, which are arranged on the rotating member 110 at intervals along the circumference, and the baffles 120 are used to be located between two adjacent filter cartridges 3.

[0033] In this embodiment, an installation space 722 is reserved between the installation portion 72 and the installation plate 2, the driving wheel 4 and the driven wheel 5 rotate in the installation space 722, and the synchronous belt 6 is circulated in the installation space 722. A rotating member 110 passes through the through hole 723 of the installation portion 72 by a suitable shaft connection method, and is fixedly connected to the driving wheel 4 or the driven wheel 5 to achieve synchronous rotation. A plurality of baffles 120 are welded or bolted to the rotating member 110 at uniform intervals along the circumferential direction of the rotating member 110, and their positions and sizes are designed to ensure that during the cyclic movement of the filter cartridge 3, the baffle 120 can be accurately located between two adjacent filter cartridges 3, thereby playing an effective isolation role.

[0034] The coordinated use of the rotating member 110 and the baffle 120 can effectively prevent dust from splashing between the filter cartridges 3 during the cleaning process, avoid secondary dust contamination, improve the cleaning effect of the isolated filter cartridge 3, and ensure the efficient operation of the entire dust removal device.

[0035] Furthermore, the mounting plate 2 also has an annular groove 22 and also includes a plurality of balls 130 . The plurality of balls 130 are rotatably disposed on the first mounting member 8 , and the plurality of balls 130 are movably disposed in the annular groove 22 .

[0036] In this embodiment, an annular groove 22 is processed on the mounting plate 2, and the surface of the annular groove 22 is polished and lubricated to reduce the friction coefficient. A plurality of balls 130 are rotatably mounted on the corresponding positions of the first mounting member 8 through a suitable retainer or inlay structure, so that they can be in close contact with the annular groove 22 and roll freely in the annular groove 22 when the first mounting member 8 moves with the synchronous belt 6.

[0037] The contact design between the ball 130 and the annular groove 22 greatly reduces the friction between the first mounting member 8 and the mounting plate 2 when the first mounting member 8 moves, thereby reducing the running resistance and energy consumption of the equipment. The friction and wear are reduced, the service life of the equipment is extended, and the stability and accuracy of the movement of the first mounting member 8 are improved, the stability of the filter cartridge 3 during the circulation and transportation process is ensured, and the dust removal efficiency is improved.

[0038] Furthermore, it also includes a third mounting member 140, which is arranged on the synchronous belt 6, and two third mounting members 140 are provided between two adjacent first mounting members 8, and the third mounting member 140 has a sliding cavity 141; the extension plate 15 is slidingly and swingingly arranged in the sliding cavity 141; one end of the elastic member 16 is arranged in the sliding cavity 141, and the other end is arranged on the extension plate 15, and the elastic member 16 is used to provide a force for the extension plate 15 to slide out of the sliding cavity 141. After the extension plate 15 slides out of the sliding cavity 141, the adjacent extension plates 15 are used to abut each other or the extension plates 15 abut against the adjacent first mounting members 8, and after abutting, they are used to close the exhaust hole 21. The extension plate 15 has an avoidance cavity 151, and also includes a mounting rod 17, which is arranged in the sliding cavity 141, and the mounting rod 17 penetrates into the avoidance cavity 151, and the mounting rod 17 has a straight groove 171; the rotating column 18 is rotatably and slidably arranged in the straight groove 171, and is arranged in the avoidance cavity 151, and the extension plate 15 is rotatably and slidably arranged on the mounting rod 17 through the rotating column 18 and the straight groove 171; There are a plurality of elastic members 16, which are respectively located on both sides of the mounting rod 17, and the other end of the elastic member 16 is rotatably mounted on the extension plate 15. The elastic members 16 on both sides of the mounting rod 17 have the same elongation but different elastic coefficients. When the third mounting plate 2 is located at a turning position, the elastic member 16 located at the large diameter of the turning position has a larger elastic coefficient, so the elongation is larger, so that the adjacent extension plate 15 can be rotated. After the rotation, the adjacent extension plates 15 and the extension plates 15 and the adjacent first mounting member 8 are always in contact, so that the unfiltered gas is prevented from being discharged from the exhaust hole 21.

[0039] In this embodiment, the third mounting member 140 is mounted on the synchronous belt 6, and a plurality of third mounting members 140 are arranged between two adjacent first mounting members 8. The extension plate 15 is slidably and rotatably mounted in the slide cavity 141. The mounting rod 17 is mounted in the slide cavity 141, and penetrates into the avoidance cavity 151 of the extension plate 15. The rotating column 18 can rotate and slide in the straight groove 171 on the mounting rod 17. The rotating column 18 is rotatably and slidably mounted in the straight groove 171, and is arranged in the avoidance cavity 151.

[0040] The design of the mounting rod 17, the rotating column 18 and the rotating sleeve provides structural support for the rotation and sliding of the extension plate 15, so that the extension plate 15 can adjust the position and angle more flexibly and accurately when closing the exhaust hole 21. After the third mounting member 140 and the extension plate 15 are installed, the middle adjacent extension plates 15 abut against each other, and the elastic member 16 is in a moderately compressed state. The extension plate 15 at the edge contacts the first mounting member 8, and the elastic member 16 is also in a moderately compressed state. When the synchronous belt 6 moves, when the third mounting member 140 moves to the turning point, the elastic member 16 at the turning point is further compressed or slightly compressed, so that the adjacent extension plates 15 are always in contact, preventing the exhaust hole 21 from leaking.

[0041] Furthermore, the accommodation space 11 has an air inlet and an outlet 13. The rust passes through the air inlet, the filter cartridge 3, the first through cavity 81, the second through cavity 91, the exhaust hole 21 and the outlet 13 in sequence. The accommodation space 11 also has a hopper 14 for collecting rust, and also includes a pulse member 20. The pulse member 20 is arranged on the housing 1. The pulse member 20 has a plurality of jet ports, which correspond to the exhaust holes 21 one by one. The pulse member 20 is used to inject high-pressure gas into the exhaust holes 21. It also includes a shot blasting member 210 for cleaning the rust on the hull; a collecting member 220 for collecting rust; and a pipe 230 having one end connected to the collecting member 220 and the other end connected to the accommodation space 11.

[0042] In this embodiment, the shot blasting element 210 is installed in the rust cleaning area on the surface of the hull, and the rust on the hull is strongly cleaned by high-speed projectiles such as abrasives, and the rust is peeled off the surface of the hull. The collecting element 220 is arranged under the hull, and the cleaned rust is collected by a suitable collection method, and the air in the hopper 14 is transported to the storage space 11 of the dust removal device through the pipeline 230. The material and diameter of the pipeline 230 are selected according to the conveying distance to ensure that the rust in the air can be transported from the collecting element 220 to the storage space 11, and at the same time, the sealing of the pipeline 230 is ensured to prevent rust leakage. The air inlet and outlet 13 of the storage space 11 are reasonably planned and designed in size to ensure that the gas can enter and exit. Impurities such as rust are collected under the action of external equipment (such as the hopper 14), and the rust powder remaining in the air is collected and transported to the storage space 11 through the pipeline 230, and first enters the area where the filter cartridge 3 is located through the air inlet. The pulse member 20 is fixedly installed in the accommodation space 11 by using a suitable mounting bracket. The number, position and direction of the jet ports correspond to the exhaust holes 21 one by one. By connecting to an external high-pressure gas source (such as an air compressor), high-pressure gas can be sprayed into the exhaust holes 21 at specific time intervals. During the dust removal process of the filter cartridge 3, when the dust on the surface of the filter cartridge 3 accumulates to a certain extent, the pulse member 20 is activated, and the high-pressure gas instantly rushes into the exhaust holes 21, impacting the filter cartridge 3 in the reverse direction, so that the dust is separated from the surface of the filter cartridge 3 and falls into the hopper 14 below.
