Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, and in particular relates to a light pleated bag cage structure. Background Art

[0002] The filter bag is the component that filters dust in the bag dust collector. The filter bag is put on the metal bag cage, and the bag cage is hung vertically in the dust collector. The dust in the extracted gas is blocked by the filter bag and falls into the dust collecting bag, and the gas that passes through the filter bag is discharged into the air.

[0003] The existing bag cages used in dust collectors mostly have star-shaped support ring structures, which results in a relatively concentrated flow field distribution in the bag cage, so that the inner folds of the bags are easily stuck together during operation, affecting the filtration area. At the same time, the top of the existing bag cages is connected with a straight pipe mouth, which shortens the service life of the filter bags during negative pressure operation.

[0006] In some embodiments, the support ring includes a support circular ring and support feet, and the support feet are circumferentially mounted on the support circular ring.

[0007] In some embodiments, one end of the support foot is connected to the support ring, and the other end is connected to the groove of the longitudinal support rod.

[0008] In some embodiments, the support foot is fixed to the groove of the longitudinal support rod by welding.

[0009] In some embodiments, the number of the supporting feet is consistent with the number of the longitudinal supporting rods.

[0010] In some embodiments, a bag cage support ring is provided on the outer circumference of the bag cage top fixing frame.

[0011] In some embodiments, the longitudinal support rod is fixed to the bottom fixing ring via a folding hook structure, and the folding hook structure is integrally formed with the longitudinal support rod.

[0012] In some embodiments, a plurality of the support rings are fixed in the cage structure at equal intervals along the length direction.

[0013] Beneficial effects: The beneficial effects of the utility model are as follows:

[0014] In the bag cage structure of the utility model, the longitudinal support rod adopts a shaped wire with a groove, which has the following effects:

[0015] First, the longitudinal support rod and the support ring are firmly attached and easy to weld;

[0023] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings. Example

[0024] like Figure 1 and Figure 3 As shown, a lightweight corrugated bag cage structure includes longitudinal support rods 2, support rings 3, a bag cage top fixing frame 4 and a bottom fixing ring 1. Multiple longitudinal support rods 2 are distributed circumferentially to form a cage structure, and the two ends of the multiple longitudinal support rods 2 are respectively fixedly connected to the bag cage top fixing frame 4 and the bottom fixing ring 1. Multiple support rings 3 are respectively fixed in the cage structure along the length direction, and grooves 34 are provided on the longitudinal support rods 2.

[0025] In the bag cage structure of the utility model, the longitudinal support rod adopts a special-shaped wire with a groove, which has the following effects: firstly, the longitudinal reinforcement and the wire of the support ring are firmly fitted and easy to weld; secondly, the weight of the longitudinal wire is reduced, thereby reducing the weight and cost of the overall keel. Example

[0026] like Figure 1 As shown, a lightweight corrugated bag cage structure includes longitudinal support rods 2, support rings 3, a bag cage top fixing frame 4 and a bottom fixing ring 1. Multiple longitudinal support rods 2 are distributed circumferentially to form a cage structure, and the two ends of the multiple longitudinal support rods 2 are respectively fixedly connected to the bag cage top fixing frame 4 and the bottom fixing ring 1. Multiple support rings 3 are respectively fixed in the cage structure along the length direction, and grooves 34 are provided on the longitudinal support rods 2.

[0027] In this embodiment, the number of the longitudinal support rods 2 is preferably six, eight, ten, or an even number greater than ten.

[0028] In this embodiment, Figure 2 As shown, the support ring 3 includes a support ring 31 and a support foot 32, and the support foot 32 is circumferentially mounted on the support ring 31. Compared with the traditional star-shaped support ring, the present application improves the flow field distribution inside the dust collector by combining the support ring 31 and the support foot 32; by changing the structure of the support ring, it is ensured that the inner folds of the bag do not stick together during operation to affect the filtering area.

[0029] Among them, Figure 2 As shown, the supporting ring 31 may adopt a plurality of ring structures, thereby increasing the strength of the supporting ring.

[0030] In this embodiment, Figure 2 and Figure 3As shown, one end of the support foot 32 is fixedly connected to the support ring 31, and the other end is fixedly connected to the groove 34 of the longitudinal support rod 2, and the connection point is a fixed node 33. Preferably, the support foot 32 and the groove 34 of the longitudinal support rod 2 are fixed by welding, and the specific structure of the welding node is as follows: Figure 3 In this embodiment, the support legs 32 and the longitudinal support rods 2 are fixed by point-to-point welding, so as to facilitate the installation and removal of the bag cage and reduce the overall manufacturing cost of the bag cage.

[0031] In the bag cage structure of this embodiment, the longitudinal support rod adopts a special-shaped wire with a groove. The effects of this are: first, the longitudinal reinforcement and the wire of the support ring fit firmly and are easy to weld; second, the weight of the longitudinal wire is reduced, thereby reducing the weight and cost of the overall keel.

[0032] In this embodiment, the number of the supporting legs 32 is consistent with the number of the longitudinal supporting rods 2 .

[0033] In this embodiment, Figure 1 As shown, a bag cage support ring 5 is provided on the outer circumferential side of the bag cage top fixing frame 4, and the bag cage can be firmly installed in the dust collector through the bag cage support ring 5 to ensure overall safe and stable operation.

[0034] In this embodiment, Figure 1 As shown, the longitudinal support rod 2 is fixed to the bottom fixing ring 1 by a folding hook structure, and the folding hook structure is integrally formed with the longitudinal support rod 2. The bottom is fixed by the folding hook structure, and only one end of the longitudinal support rod 2 needs to be bent, and then welded and fixed, which simplifies the production process, saves costs, and ensures the stability of the connection.

[0035] In this embodiment, a plurality of the support rings 3 are fixed in the cage structure at equal intervals along the length direction. The support rings 3 are fixed at equal intervals along the length direction. On the one hand, they can act as reinforcing ribs to improve the stability of the overall bag cage; on the other hand, by installing the support rings 3 at equal intervals, the flow field distribution inside the dust collector can be further improved to ensure that the inner folds of the bags do not stick together during operation to affect the filtration area.

[0036] The lightweight pleated bag cage structure in this embodiment improves the flow field distribution inside the dust collector by changing the structure of the support ring; by changing the structure of the support ring, it is ensured that the inner folds of the bag do not stick together during operation, affecting the filtration area.

[0037] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
