Description

Technical Field

[0001] The utility model relates to the technical field of bag-type or electric bag dust collectors, and in particular to a clean air chamber top structure adapted to a metal filter bag, a clean air collector and a dust filtering device. Background Art

[0002] Bag filter or electric bag filter is a dry dust filtering device. At present, most of the filter bag area of ​​the dust collector adopts a clean air chamber structure above the filter bag area, which is mainly fixed by welding technology. Whether it is the installation of filter bags for new projects or the replacement of some filter bags for renovation and maintenance, the filter bags need to be cut and disassembled on site.

[0003] However, in actual projects, since filter bags are often long, up to 8 to 10 meters, and the installation space of the clean air chamber is limited, the filter bags cannot be installed as a whole and need to be installed in sections on site. This is especially true for on-site installation of metal filter bags, which is time-consuming and costly.

[0004] The on-site installation of metal filter bags involves gluing of sealing gaskets, locking bolts and docking, and ensuring the height of the clean air chamber, which greatly affects the construction period and installation cost. It is also difficult to ensure the accuracy of filter bag installation and the tightness of bolts, which may affect the verticality and air tightness of the filter bags, and it is more likely to cause filter bag damage during on-site installation. For example, if an 8-meter filter bag is divided into two 4-meter short filter bags for on-site installation, the clean air chamber still needs to ensure an installation height of more than 4 meters. Utility Model Content

[0005] A technical problem to be solved by the utility model is that the filter bag cannot be installed in an integral manner due to the limited installation space of the clean air chamber of the existing dust filtering device.

[0006] In order to solve the above technical problems, a first aspect of an embodiment of the utility model provides a clean air chamber top structure adapted for a metal filter bag.

[0007] The top structure of the clean air chamber is used for a purifier, and includes:

[0008] A clean air chamber top plate, the clean air chamber top plate comprising a straight plate overlapped with a side plate of the clean air chamber and an inclined plate arranged at an extended end of the straight plate, and two inclined plates of the clean air chamber top plate are overlapped obliquely downward to form a top surface of the clean air chamber;

[0009] A sliding assembly, the sliding assembly comprising slide rails relatively arranged on both sides of the top of the clean air chamber, and a pulley assembly for supporting the top plate of the clean air chamber to move toward or away from each other along the slide rails;

[0010] The top surface of the clean air chamber is configured such that the top plates of the clean air chamber move away from each other to form an installation space for installing a filter bag.

[0011] The top structure of the clean air chamber adapted to the metal filter bag provided by the utility model is provided by setting the top surface of the clean air chamber to include two clean air chamber top plates, and the top of the clean air chamber is provided to include a straight plate overlapped with the side plates of the clean air chamber and an inclined plate arranged at the extended end of the straight plate. By using the slide rails relatively arranged on both sides of the top of the clean air chamber and the sliding assembly used to support the top plates of the clean air chamber to move toward / away along the slide rails, the top plates of the clean air chamber overlap to form a complete top surface of the clean air chamber when they move toward each other under the drive of the pulley assembly, and the top plates of the clean air chamber can form an installation space for installing the filter bag when they move away from each other under the drive of the pulley assembly, so as to provide working conditions for realizing the overall installation of the filter bag from the top surface of the clean air chamber. Thereby, it is avoided that the existing clean air chamber needs to be split and installed when installing or replacing the filter bag due to the closed space, and then the technical problem that the filter bag cannot be installed in an integral manner due to the limited installation space of the clean air chamber of the existing dust filtering device is solved.

[0012] Preferably, a sealing strip is provided between the side plate and the top surface of the clean air chamber.

[0013] Preferably, a limiting groove is provided on one side where the straight plate overlaps with the side plate, and a sealing gasket is provided at the limiting groove.

[0014] Preferably, a support assembly is provided between the straight plate and the side plate, and the support assembly comprises a support rod and an angle adjustment member for adjusting the angles of at least two of the support rods.

[0015] Preferably, the top structure of the clean air chamber comprises an angle steel arranged along its central axis, and the angle steel is arranged on the side plate through a sealing plate.

[0016] Preferably, the top structure of the clean air chamber comprises a limiting member and a limiting hole for limiting the movement of the pulley assembly, the limiting hole is arranged on the straight plate, and the limiting member is arranged in the limiting hole.

[0017] Preferably, the clean air chamber top structure comprises a motor for driving the pulley assembly.

[0018] Preferably, the pulley assembly comprises a universal wheel.

[0038] like Figures 1 to 7As shown, the utility model provides a clean air chamber top structure adapted to a metal filter bag, the clean air chamber top structure is used for a purifier, and includes a clean air chamber top plate 1 and a sliding assembly 3, the clean air chamber top plate 1 includes a straight plate 101 overlapped with a side plate 2 of the clean air chamber and an inclined plate 102 arranged at an extended end of the straight plate 101, wherein the extended end of the straight plate 101 is directed to a radially inward extending direction of the clean air chamber, the straight plate 101 and the inclined plate 102 can be welded or integrally formed, and in order to facilitate construction and match different clean air chamber sizes, preferably, the straight plate 101 and the inclined plate 102 are welded. The inclined plates 102 of the two clean air chamber top plates 1 are overlapped obliquely downward to form a clean air chamber top surface 0. The sliding assembly 3 includes a slide rail 301 relatively arranged on both sides of the top of the clean air chamber, and a pulley assembly 302 for supporting the top plate 1 of the clean air chamber to move toward / away along the slide rail. Preferably, the pulley assembly 302 includes a universal wheel, so that the sliding assembly 3 supports the top plate 1 of the clean air chamber to adjust the position movement. The top surface 0 of the clean air chamber is set so that the top plate 1 of the clean air chamber moves away from each other to form an installation space 4 for installing the filter bag 13, so as to avoid the situation that the filter bag cannot be installed properly in the conventional installation of the filter bag in the clean air chamber. The top structure of the clean air chamber provided by the utility model is mainly suitable for metal filter bags, and can also be applied to other forms of filter bags.

[0039] The top structure of the clean air chamber adapted to the metal filter bag provided by the utility model is provided with the top surface of the clean air chamber including two clean air chamber top plates 1, and the top of the clean air chamber is provided with a straight plate 101 overlapped with the side plates 2 of the clean air chamber and an inclined plate 102 arranged at the extended end of the straight plate 101. By using the slide rails 301 relatively arranged on both sides of the top of the clean air chamber and the sliding assembly 3 used for supporting the top plates 1 of the clean air chamber to move toward / away along the slide rails 301, the top plates 1 of the clean air chamber overlap to form a complete top surface 0 of the clean air chamber when they move toward each other under the drive of the pulley assembly 302, and the top plates 1 of the clean air chamber can form an installation space 4 for installing the filter bag 13 when they move away from each other under the drive of the pulley assembly 302, so as to provide working conditions for realizing the overall installation of the filter bag 13 from the top surface 0 of the clean air chamber. This avoids the situation in which the filter bag 13 needs to be disassembled and installed when installing or replacing the filter bag 13 due to the closed space in the existing clean air chamber, thereby solving the technical problem that the filter bag cannot be installed as a whole due to the limited installation space of the clean air chamber of the existing dust filtering device.

[0040] During use, the filter bag 13 can be moved toward the installation space 4 in close contact with the inclined plate 102 until it is installed in the filter bag area below the blowing pipe 14. Since the filter bag 13 does not need to be installed in a closed clean air chamber, the distance from the top surface 0 of the clean air chamber to the blowing pipe 14 can be shortened accordingly, thereby achieving the effect of reducing production costs. The filter bag 13 can be directly installed without being disassembled, which shortens the installation or replacement period of the filter bag 13, and can effectively improve production efficiency and reduce production costs.

[0041] It should be noted that after the installation of the filter bag 13 is completed, the pulley assembly 302 supports the clean air chamber top plate 1 to move toward each other until the respective inclined plates 102 overlap. At this time, in order to ensure the air tightness of the clean air chamber, the overlapping positions between the inclined plates 102 are connected by welding. When the filter bag 13 is replaced subsequently, the filter bag 13 is replaced by cutting the welding seams between the inclined plates 102 and then welding is performed to achieve the integrity of the clean air chamber structure and function.

[0042] In an optional embodiment of the utility model, a sealing strip 5 is provided between the side panel 2 and the top surface 0 of the clean air chamber. It should be noted that the upper part of the clean air chamber is formed by enclosing four side panels 2. The sealing strip 5 provided between the side panel 2 and the top surface 0 of the clean air chamber can effectively ensure the airtightness of the clean air chamber and ensure the realization of its own functionality.

[0043] In an optional embodiment of the utility model, a limiting groove 1011 is provided on one side where the straight plate 101 overlaps the side plate 2. The setting of the limiting groove 1011 can effectively fix the position between the straight plate 101 and the side plate 2 when the top plate 1 of the clean air chamber moves toward each other until the inclined plate 102 overlaps to form a complete top surface 0 of the clean air chamber, and at the same time improve the air tightness of the clean air chamber. In a further optional embodiment, a sealing gasket 6 is provided at the limiting groove 1011 to further improve the tightness of the buckling of the straight plate 101 and the side plate 2, so as to ensure the compactness of the clean air chamber structure and the integrity of the function.

[0044] In an optional embodiment of the utility model, when the pulley assembly 302 drives the top plate 1 of the clean air chamber to move away from each other, the straight plate 101 moves relative to the side plate 2 to the outside of the clean air chamber. In order to ensure the stability of the structure, a support can be provided at the bottom of the straight plate 101 or a slide rail that can support itself can be provided along its sliding track. In a preferred embodiment of the utility model, a support assembly 7 is provided between the straight plate 101 and the side plate 2. The support assembly 7 is located outside the clean air chamber. The support assembly 7 includes a support rod 701, wherein the support rod 701 can be multiple, and an angle adjustment member 702 for adjusting the connection of at least two support rods 701 to ensure that the straight plate 101 is always in an effectively supported state during the movement relative to the side plate 2, and even ensure that the support force per unit area of ​​the straight plate 101 moved to the outside of the clean air chamber is the same, so as to ensure the stability of the overall structure during the adjustment process.

[0045] In an optional embodiment of the utility model, the top structure of the clean air chamber includes an angle steel 8 arranged along its central axis, and the angle steel 8 is arranged on the side plate 2 through a sealing plate 9. The setting of the sealing plate 9 facilitates the installation of the angle steel 8, and avoids the angle steel 8 directly being installed on the side plate 2 to cause structural damage to the side plate 2. The setting of the angle steel 8 can improve the stability of the overall structure of the top of the clean air chamber. After the installation or replacement of the filter bag is achieved, the angle steel 8 is welded to the adjacent clean air chamber top plate 1, and the connection is cut and disconnected when the filter bag 13 is replaced again.

[0046] In a further optional embodiment of the utility model, the angle steel 8 is buckled on the clean air chamber top plate 1. When the clean air chamber top plate 1 completes the longitudinal direction movement of the clean air chamber top plate 1, and the inclined plate 102 is overlapped and the welding is completed, the pulley assembly 302 changes direction to drive the clean air chamber top plate 1 to move laterally along the clean air chamber. At this time, the angle steel 8 is arranged along the longitudinal direction of the clean air chamber, and the pulley assembly 302 drives the clean air chamber top plate 1 to move laterally, so that the clean air chamber top surface 0 where the clean air chamber top plate 1 and the angle steel 8 have been welded generates tension. Then the pulley assembly 302 is fixed in position. The clean air chamber top surface 0 will be driven by the rebound force of the angle steel 8 to offset the prestress generated by the previous lateral movement driven by the pulley assembly 302, thereby making the clean air chamber structure more stable.

[0047] In order to fix the relative position of the pulley assembly 302 and the top plate 1 of the clean air chamber, in an optional embodiment of the utility model, the top structure of the clean air chamber includes a limiter 10 and a limiter hole 1012 for limiting the movement of the pulley assembly 302, wherein the limiter hole 1012 is provided on the straight plate 101, and the limiter 10 is provided in the limiter hole 1012. The limiter 10 can be a latch or a lock ring, and the limiter hole 1012 is adapted to the latch or the lock ring.

[0048] In an optional embodiment of the utility model, the top structure of the clean air chamber includes a motor 11 for driving the pulley assembly 302 to ensure the normal operation of the pulley assembly 302. Further, the motor 11 can drive the pulley of the pulley assembly 302 to perform steering operations to adapt the clean air chamber pulley assembly 302 to adjust the supporting position of the clean air chamber top plate 1.

[0049] The utility model provides an air purifier adapted for a metal filter bag. The air purifier comprises a dust collector 12 and a air purifier chamber connected to the dust collector 12. The air purifier chamber comprises any one of the above-mentioned air purifier chamber top structures.

By using the slide rails 301 relatively arranged on both sides of the top of the clean air chamber and the sliding assembly 3 used for supporting the top plates 1 of the clean air chamber to move toward / away along the slide rails 301, the top plates 1 of the clean air chamber overlap to form a complete top surface 0 of the clean air chamber when they move toward each other under the drive of the pulley assembly 302, and the top plates 1 of the clean air chamber can form an installation space 4 for installing the filter bag 13 when they move away from each other under the drive of the pulley assembly 302, so as to provide working conditions for realizing the overall installation of the filter bag 13 from the top surface 0 of the clean air chamber. This avoids the situation in which the filter bag 13 needs to be disassembled and installed when installing or replacing the filter bag 13 due to the closed space in the existing clean air chamber, thereby solving the technical problem that the filter bag cannot be installed as a whole due to the limited installation space of the clean air chamber of the existing dust filtering device.

[0052] The top structure of the clean air chamber of the dust filter device adapted to the metal filter bag provided by the utility model is provided by setting the top surface of the clean air chamber to include two clean air chamber top plates 1, and the top of the clean air chamber is provided to include a straight plate 101 overlapped with the side plate 2 of the clean air chamber and an inclined plate 102 arranged at the extended end of the straight plate 101. By using the slide rails 301 relatively arranged on both sides of the top of the clean air chamber and the sliding assembly 3 used for supporting the top plate 1 of the clean air chamber to move toward / away along the slide rails 301, the top plates 1 of the clean air chamber are overlapped to form a complete top surface 0 of the clean air chamber when they move toward each other under the drive of the pulley assembly 302, and the top plates 1 of the clean air chamber are able to form an installation space 4 for installing the filter bag 13 when they move away from each other under the drive of the pulley assembly 302, so as to provide working conditions for realizing the overall installation of the filter bag 13 from the top surface 0 of the clean air chamber. This avoids the situation in which the filter bag 13 needs to be disassembled and installed when installing or replacing the filter bag 13 due to the closed space in the existing clean air chamber, thereby solving the technical problem that the filter bag cannot be installed as a whole due to the limited installation space of the clean air chamber of the existing dust filtering device.
