Description

Technical Field

[0001] This utility model relates to the field of environmental protection auxiliary equipment technology, and more specifically, to a pulse dust collector filter bag disassembly device. Background Technology

[0002] After prolonged use (1-3 years), the filter bags of cylindrical pulse bag dust collectors usually need to be replaced in batches to ensure the dust removal efficiency of the dust collector.

[0003] Currently, filter bags typically have a flexible steel ring inside the bag head. This ring tightly supports the tube sheet opening, securing the bag head and suspending it within the pulse jet baghouse dust collector's air chamber. Disassembling the filter bags usually requires operators to use pry bars or flathead screwdrivers to forcibly separate the bag head from the tube sheet opening, resulting in inconvenient operation, low bag disassembly efficiency, and high labor intensity.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the present utility model will be described in more detail below with reference to the accompanying drawings of the preferred embodiments. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this utility model. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] In the description of this embodiment, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "level", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this embodiment.

[0033] like Figure 1 As shown, this utility model embodiment provides a pulse dust collector bag disassembly device, including two force-applying rods 1, which are arranged crosswise and rotatably connected. It can be understood that the two force-applying rods 1 are rotatably connected at the crosswise position. Each force-applying rod 1 includes a first end 11 and a second end 12 opposite to each other; a first clamping part is disposed at the first end 11 of one force-applying rod 1; and a second clamping part is disposed at the first end 11 of the other force-applying rod 1. The first clamping part and the second clamping part are used to clamp the bag head; the second ends 12 of the two force-applying rods 1 are used to bring them closer together, thereby causing the first clamping part and the second clamping part to move closer together, thus deforming the bag head.

[0034] Understandably, the filter bags in a pulse jet dust collector have elastic steel rings inside their bag heads, and a circumferentially extending groove is provided on the outer wall of the bag head. The bag head is engaged with the tube sheet hole through this groove, with the portion of the bag head above the groove protruding from the outside of the tube sheet. When disassembling the filter bag, the first and second clamping parts can be used to clamp the portion of the bag head protruding from the outside of the tube sheet.

[0035] The pulse dust collector bag disassembly device provided in this embodiment allows for bag disassembly by holding the second ends 12 of the two force-applying rods 1 and clamping the first and second clamping parts on both sides of the bag head. Then, a force is applied to the two force-applying rods 1 to bring the first and second clamping parts closer together and clamp the bag head until the bag head is deformed, i.e., the steel ring inside the bag head is deformed, allowing the bag to be removed. This facilitates bag disassembly, improves bag disassembly efficiency, and reduces the labor intensity of operators.

[0036] In some embodiments, see Figure 1 The first clamping part may include a first ring hoop 2; the second clamping part may include a second ring hoop 3, wherein at least the outline shape of the first ring hoop 2 and the second ring hoop 3 is an arc shape that matches the outline shape of the bag head; the first ring hoop 2 and the second ring hoop 3 have the same bending direction, and the length of the first ring hoop 2 is greater than the length of the second ring hoop 3.

[0037] Since the bag head has a circular outline, the first ring 2 is designed with a matching arc shape to ensure stable clamping of the bag head. Simultaneously, the second ring 3 is also arc-shaped, and the first and second rings 2 bend in the same direction. This allows the concave side of the first ring 2 to clamp the bag head while the convex side of the second ring 3 clamps it during bag disassembly. When the first and second rings 2 and 3 come together and clamp the bag head, the first ring 2 can fix the bag head, while the second ring 3 can apply a force towards its center, easily deforming the bag head—that is, easily deforming the steel ring inside the bag head—thus facilitating bag disassembly and further improving disassembly efficiency.

[0038] The length of the first ring 2 is greater than the length of the second ring 3, thereby increasing the circumferential length of the first ring 2 surrounding the bag head and improving the clamping stability of the first ring 2. As for the second ring 3, its convex side clamps the bag head. Therefore, as long as the second ring 3 can reliably apply force to the bag head, its length can be minimized, thus saving materials and reducing costs.

[0039] In some embodiments, the second ring 3 is opposite to the middle of the first ring 2 to increase the force applied by the second ring 3 to the bag head, thereby making it easier to deform the bag head and further improving the disassembly efficiency of the cloth bag.

[0040] In some embodiments, see Figure 1 The first ring hoop 2 can have an L-shaped cross-section. The first ring hoop 2 includes a first hoop plate 21 and a second hoop plate 22 connected together. The first hoop plate 21 is used to clamp the bag head, and the second hoop plate 22 is connected to the first end 11 of a force-applying rod 1. The second ring hoop 3 can also have an L-shaped cross-section. The second ring hoop 3 includes a third hoop plate 31 and a fourth hoop plate 32 connected together. The third hoop plate 31 is used to clamp the bag head, and the fourth hoop plate 32 is connected to the first end 11 of another force-applying rod 1.

[0041] When disassembling the filter bag, the first hoop plate 21 of the first ring hoop 2 and the third hoop plate 31 of the second ring hoop 3 can be inserted into the gap between the bag head and the tube sheet, so that the first hoop plate 21 and the third hoop plate 31 can be inserted into the slot of the aforementioned bag head, apply force to the bag head to deform the bag head, improve the clamping stability of the first clamping part and the second clamping part on the bag head, thereby improving the reliability of the filter bag disassembly device of the pulse dust collector.

[0042] Specifically, the first hoop 21 and the second hoop 22 are integrally formed and connected; the third hoop 31 and the fourth hoop 32 are integrally formed and connected to improve the strength of the first hoop 2 and the second hoop 3, thereby improving the strength of the entire disassembly device.

[0043] In some embodiments, the first ring 2 is rotatably disposed relative to a force-applying rod 1, and the rotation range of the first ring 2 is located within the circle in which the first ring 2 is located; the second ring 3 is rotatably disposed relative to another force-applying rod 1, and the rotation range of the second ring 3 is located within the circle in which the second ring 3 is located.

[0044] By configuring the first ring clamp 2 and the second ring clamp 3 to be rotatable relative to the force-applying rod 1, this pulse dust collector bag removal device can be applied to the removal of bags with various inner diameters. Furthermore, if foreign objects are present at the construction site, rigid contact is less likely to occur when the first ring clamp 2 and the second ring clamp 3 interfere with the foreign objects, thus preventing damage and extending the service life of the device.

[0045] Specifically, the second hoop plate 22 of the first ring hoop 2 can be rotatably connected to the force-applying rod 1, and the fourth hoop plate 32 of the second ring hoop 3 can be rotatably connected to the force-applying rod 1.

[0046] In some embodiments, see Figure 1 The first clamping part may also include a first connecting rod 4, one end of which is connected to the middle of the first ring 2, and the other end of which is rotatably connected to the first end 11 of a force-applying rod 1; the second clamping part may also include a second connecting rod 5, one end of which is connected to the middle of the second ring 3, and the other end of which is rotatably connected to the first end 11 of another force-applying rod 1.

[0047] Specifically, one end of the first connecting rod 4 can be connected to the second hoop plate 22 of the first ring 2, and the second hoop plate 22 is rotatably connected to the force-applying rod 1 through the first connecting rod 4; one end of the second connecting rod 5 can be connected to the fourth hoop plate 32 of the second ring 3, and the fourth hoop plate 32 is rotatably connected to the force-applying rod 1 through the second connecting rod 5.

[0048] In this design, one end of the first connecting rod 4 can be provided with a first slot, into which the first ring clamp 2 is inserted. Specifically, the second clamp plate 22 is inserted into the first slot. The extension direction of the first slot is different from the force applied to the bag head by the first ring clamp 2, such as being perpendicular to each other. Similarly, one end of the second connecting rod 5 can be provided with a second slot, into which the second ring clamp 3 is inserted. Specifically, the fourth clamp plate 32 is inserted into the second slot. The extension direction of the second slot is different from the force applied to the bag head by the second ring clamp 3, such as being perpendicular to each other. This structural arrangement makes the installation of the force-applying rod 1 with the first ring clamp 2 and the second ring clamp 3 more convenient and more reliable.

[0049] In some embodiments, a first accommodating gap is provided between the end of the first connecting rod 4 and the first ring 2, specifically, a first accommodating gap is provided between the end of the first connecting rod 4 and the first hoop 21; a second accommodating gap is provided between the end of the second connecting rod 5 and the second ring 3, specifically, a second accommodating gap is provided between the second connecting rod 5 and the third hoop 31.

[0050] When disassembling the cloth bag, the first hoop 21 and the third hoop 31 are inserted between the bag head and the tube sheet, and the bag head can be accommodated in the first accommodating gap and the second accommodating gap, so that the first hoop 21 and the third hoop 31 can clamp the bag head smoothly.

[0051] In some embodiments, the two force-applying rods 1 have a rotatable connection position, and the distance between the second end 12 of the force-applying rod 1 and the rotatable connection position is greater than or equal to the distance between the first end 11 of the force-applying rod 1 and the rotatable connection position, thereby increasing the lever arm, reducing the force applied by the operator to the force-applying rod 1, and further reducing the labor intensity of the operator.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
