Description

Technical Field

[0001] The utility model belongs to the technical field of two-filter cartridge type dust collectors, and in particular relates to a two-filter cartridge type dust collector which is convenient for maintenance. Background Art

[0002] The cartridge dust collector is a common and important air purification equipment, which is widely used in industrial production, mining, chemical industry, metallurgy and other industries. Its main function is to effectively remove suspended solid particles, smoke and dust in the air through filtering and separation processes, improve indoor air quality, and protect the environment and human health;

[0003] The double-layer filter cartridges of the existing two-filter cartridge type dust collector are usually fixed by threaded connection. During maintenance, only one filter cartridge can be unscrewed at a time, which makes the operation more cumbersome for the staff and inconvenient for the relevant staff to maintain the two-filter cartridge type dust collector, making the maintenance of the two-filter cartridge type dust collector less convenient and easy. For this reason, we propose a two-filter cartridge type dust collector that is easy to maintain. Utility Model Content

[0004] The utility model aims to provide a two-filter cartridge dust collector which is convenient for maintenance, so as to solve the technical problems raised in the background technology.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows: a two-filter cartridge dust collector that is easy to repair, including a dust removal box and a structure that is easy to disassemble,

[0006] Dust removal box: A box door is hingedly provided on the left side of the opening arranged on the front surface thereof, a dust inlet is provided in the dust inlet arranged in the middle of the right surface of the dust removal box, an air outlet is provided in the air outlet arranged in the middle of the upper surface of the dust removal box, a mounting frame is provided at the upper end of the inner cavity of the dust removal box, a sliding plate is slidably connected between the left and right walls of the mounting frame through a dovetail slide groove, and double-layer filter cartridges are movably inserted in the sockets evenly arranged in the middle of the sliding plate;

[0007] Easy-to-disassemble structure: It is arranged on the lower surface of the sliding plate, and the easy-to-disassemble structure is movably connected with the sockets corresponding to the upper ends of the outer arc surfaces of the double-layer filter cartridges adjacent to the same side, so that relevant staff can inspect and repair the two-cartridge dust collector, improve the convenience and convenience of maintenance, and facilitate the later inspection and repair of a single double-layer filter cartridge. At the same time, all double-layer filter cartridges on the two-cartridge dust collector can be removed in batches for inspection and repair, which greatly improves the inspection and repair efficiency of the two-cartridge dust collector and makes the two-cartridge dust collector more convenient and quick to repair.

[0008] Preferably, the detachable structure includes a fixed plate, a U-shaped plate, dovetail grooves, and limit plates. The fixed plates are symmetrically arranged horizontally at the front end of the middle part of the lower surface of the sliding plate. A U-shaped plate is slidably connected longitudinally between the two fixed plates. Dovetail grooves are evenly distributed longitudinally on the left and right surfaces of the longitudinal plates of the U-shaped plate. Limit plates are slidably connected longitudinally in the dovetail grooves, and the limit plates are respectively inserted into the sockets corresponding to the upper ends of the outer arcs of the adjacent double-layer filter cartridges on the same side, greatly improving the maintenance efficiency of the two-filter-cartridge dust collector.

[0009] Preferably, circular plates are provided at the rear ends of the middle parts of the longitudinal plates of the U-shaped plate. Between the front end surfaces of the circular plates and the rear surfaces of the fixed plates, there are first springs respectively sleeved on the outside of the vertically adjacent longitudinal plates on the U-shaped plate, which play an elastic supporting role for the U-shaped plate and its attached mechanisms.

[0010] Preferably, between the front surface of the limit plate and the front wall surface of the dovetail groove where it is located, there are second springs, which play an elastic supporting role for the limit plate.

[0011] Preferably, an observation window is provided in the middle of the front surface of the box door, which is convenient for the staff to directly observe the internal situation of the two-filter-cartridge dust collector.

[0012] Preferably, support legs are fixedly installed at the lower ends of the left and right surfaces of the dust removal box by bolts, which play a supporting role for the dust removal box and its attached mechanism units.

[0013] A two-filter-cartridge dust collector that is convenient for maintenance of the present utility model has the following advantages:

[0014] 1. For this two-filter-cartridge dust collector that is convenient for maintenance, by opening the box door and then pulling the sliding plate outwards, the double-layer filter cartridge and its attached mechanisms can be pulled out of the dust removal box, thereby facilitating the relevant staff to maintain the two-filter-cartridge dust collector, thus improving the convenience and efficiency of maintenance.

[0015] 2. For this two-filter-cartridge dust collector that is convenient for maintenance, by pulling the corresponding limit plate outwards, the limit plate moves outwards against the elastic force of the second spring, so that the limit plate is separated from the socket corresponding to the upper end of the outer arc of the double-layer filter cartridge. At this time, the double-layer filter cartridge to be maintained can be pulled out downwards, thus facilitating the subsequent maintenance of a single double-layer filter cartridge. When all the double-layer filter cartridges need to be maintained, the relevant staff pull the U-shaped plate outwards. The U-shaped plate drives the limit plate and the circular plate to move outwards synchronously against the elastic force of the first spring, so that the limit plate is separated from the socket corresponding to the upper end of the outer arc of the double-layer filter cartridge. At this time, the double-layer filter cartridges can be pulled out downwards in sequence, and all the double-layer filter cartridges on the two-filter-cartridge dust collector can be removed for maintenance in one batch, greatly improving the maintenance efficiency of the two-filter-cartridge dust collector and making the two-filter-cartridge dust collector more convenient and fast during maintenance.

[0027] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a two-filter cartridge dust collector that is easy to maintain in the utility model in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, the utility model is a two-filter cartridge dust collector which is convenient for maintenance, comprising a dust removal box 1 and a structure 8 which is convenient for disassembly.

[0029] Dust removal box 1: The dust removal box 1 provides a place for installation and support for its subsidiary mechanism units. The left side of the opening arranged on the front surface thereof is hinged with a box door 2, which plays a sealing role. The dust inlet arranged in the middle of the right surface of the dust removal box 1 is provided with a dust inlet pipe 3, and the air outlet arranged in the middle of the upper surface of the dust removal box 1 is provided with an air outlet pipe 4. The upper end of the inner cavity of the dust removal box 1 is provided with a mounting frame 5, and the left and right walls of the mounting frame 5 are slidably connected with a sliding plate 6 through a dovetail slide groove, and the double-layer filter is movably inserted in the sockets evenly arranged in the middle of the sliding plate 6. The filter cartridge 7 first connects the air inlet of the external exhaust fan with the air outlet pipe 4, then connects the dust inlet pipe 3 with the external dust outlet, and then uses the external exhaust fan to draw the dust-containing air from the dust inlet pipe 3 into the interior of the dust inlet pipe 3, and then passes through the double-layer filter cartridge 7, which can more effectively filter out fine particles. The first filter layer is used to capture larger particles, reduce the pressure on the second filter layer, and improve the overall filtration efficiency. The second filter layer filters the air more finely and can better capture fine particles, thereby facilitating the filtration and dust removal of the incoming air;

[0030] The convenient disassembly structure 8 is arranged on the lower surface of the sliding plate 6, and the convenient disassembly structure 8 is respectively movably connected with the sockets corresponding to the upper ends of the outer arc surfaces of the double-layer filter cartridges 7 adjacent to the same side. The convenient disassembly structure 8 includes a fixed plate 81, a convex plate 82, a dovetail groove 83 and a limit plate 84. The fixed plate 81 is laterally symmetrically arranged at the front end of the middle part of the lower surface of the sliding plate 6, and a convex plate 82 is longitudinally slidably connected between the two fixed plates 81. The left and right surfaces of the longitudinal plate body of the convex plate 82 are provided with dovetail grooves 83 uniformly distributed in the longitudinal direction. The dovetail grooves 83 are longitudinally slidably connected to the limit plates 84. The limit plates 84 are respectively movably connected with the sockets corresponding to the upper ends of the outer arc surfaces of the double-layer filter cartridges 7 adjacent to the same side. When it is necessary to inspect the two-cartridge dust collector, the relevant staff first opens the box door 2, and then pulls the sliding plate 6 outward to pull the double-layer filter cartridge 7 and its auxiliary mechanisms out of the dust removal box 1, thereby facilitating the relevant staff to inspect the two filters. The double-layer filter cartridge 7 can be repaired and maintained by pulling out the corresponding limit plate 84, so that the limit plate 84 is separated from the corresponding socket provided on the upper end of the outer arc surface of the double-layer filter cartridge 7. At this time, the double-layer filter cartridge 7 that needs to be repaired can be pulled out downward, so that it is convenient to repair the single double-layer filter cartridge 7 at a later time. When all the double-layer filter cartridges 7 need to be repaired, the relevant staff pulls the convex plate 82 outward, and the convex plate 82 drives the limit plate 84 and the circular plate 9 to move outward synchronously, so that the limit plate 84 is separated from the corresponding socket provided on the upper end of the outer arc surface of the double-layer filter cartridge 7. At this time, the double-layer filter cartridge 7 can be pulled out downward in turn, and all the double-layer filter cartridges 7 on the two-filter cartridge type dust collector can be removed for maintenance in one batch, which greatly improves the maintenance efficiency of the two-filter cartridge type dust collector, making the two-filter cartridge type dust collector more convenient and quick during maintenance.

[0031] Among them: circular plates 9 are provided at the rear ends of the middle parts of the longitudinal plates of the U-shaped plate 82. Between the front end faces of the circular plates 9 and the rear surfaces of the fixing plates 81, first springs 10 are provided. The first springs 10 are respectively sleeved on the outer parts of the vertically adjacent longitudinal plates on the U-shaped plate 82. The circular plates 9 and the first springs 10 cooperate with each other to elastically support the U-shaped plate 82 and its attached mechanism.

[0032] Among them: between the front surface of the limit plate 84 and the front wall surface of the dovetail groove 83 where it is located, second springs 11 are provided. The second springs 11 elastically support the limit plate 84.

[0033] Among them: an observation window 12 is provided in the middle of the front surface of the box door 2. The observation window 12 facilitates the staff to directly observe the internal situation of the two-filter cartridge dust collector, so as to determine whether maintenance is required.

[0034] Among them: support legs are fixedly installed at the lower ends of the left and right surfaces of the dust removal box 1 through bolts, which can support the dust removal box 1 and its attached mechanism unit.

[0035] The working principle of the two-filter cartridge dust collector which is easy to maintain is as follows: first, the air inlet of the external exhaust fan is connected with the air outlet pipe 4, and then the dust inlet pipe 3 is connected with the external dust outlet. Thereafter, the dust-containing air is drawn into the interior of the dust inlet pipe 3 from the dust inlet pipe 3 through the external exhaust fan, and then passes through the double-layer filter cartridge 7, which can more effectively filter out fine particles. The first filter layer is used to capture larger particles, reduce the pressure on the second filter layer, and improve the overall filtration efficiency. The second filter layer filters the air more finely and can better capture fine particles, thereby facilitating the filtration and dust removal of the incoming air. When it is necessary to maintain the two-filter cartridge dust collector, the relevant staff first opens the box door 2, and then pulls the sliding plate 6 outward to pull the double-layer filter cartridge 7 and its auxiliary mechanisms out of the dust removal box 1, thereby facilitating the relevant staff to maintain the two-filter cartridge dust collector, thereby improving the convenience and convenience of maintenance. When the double-layer filter cartridge 7 is removed for maintenance, it is only necessary to pull the corresponding limit plate 84 outwards, and the limit plate 84 overcomes the elastic force of the spring 11 and moves outwards, so that the limit plate 84 is separated from the corresponding socket set on the upper end of the outer arc surface of the double-layer filter cartridge 7. At this time, the double-layer filter cartridge 7 that needs to be repaired can be pulled out downwards, so that it is convenient to repair a single double-layer filter cartridge 7 later. When all the double-layer filter cartridges 7 need to be repaired, the relevant staff pulls the convex plate 82 outwards, and the convex plate 82 drives the limit plate 84 and the circular plate 9 to overcome the elastic force of the spring 10 and move outwards synchronously, so that the limit plate 84 is separated from the corresponding socket set on the upper end of the outer arc surface of the double-layer filter cartridge 7. At this time, the double-layer filter cartridge 7 can be pulled out downwards in turn, and all the double-layer filter cartridges 7 on the two-cartridge dust collector can be removed for maintenance in one batch, which greatly improves the maintenance efficiency of the two-cartridge dust collector and makes the two-cartridge dust collector more convenient and quick during maintenance.

[0036] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
