Description

Technical Field

[0001] This utility model belongs to the field of dust collector technology, specifically relating to a bag cage structure for a bag filter. Background Technology

[0002] Filter bags are crucial components in baghouse dust collectors for filtering dust. The filter bags are fitted onto metal cages, which support the filter bags to prevent them from collapsing due to the negative pressure inside the dust collector, thus ensuring the filter bags maintain their proper filtration efficiency. Therefore, matching the cage and filter bag is extremely important; different filter bag materials and diameters require different cage configurations.

[0003] Due to the unique design of the M-type filter bag and the optimized filtration performance, the M-type bag cage structure requires further optimization. Adjacent pleats are alternately arranged with varying sizes, ensuring that the pleats do not overlap during operation, thus preventing any impact on the filtration area. Furthermore, the well-designed support of the bag cage allows for more airflow space within the filter bag, thereby reducing the operating resistance of the dust collector. Utility Model Content

[0006] The transverse support of the bag cage includes a bending part and a support part, and the bending part includes multiple sets of interconnected "M"-shaped connectors.

[0007] In some embodiments, the transverse support of the bag cage is installed inside the longitudinal main reinforcement of the bag cage.

[0014] Beneficial effects: The beneficial effects of this utility model are as follows:

[0028] Example 1

[0029] like Figure 1 As shown, a bag cage structure for a bag filter includes a bag cage body 1. The bag cage body 1 includes longitudinal main ribs 2, transverse support members 3, a bottom 4, and a top 5. Multiple longitudinal main ribs 2 are arranged circumferentially, and their two ends are respectively fixedly connected to the bottom 4 and the top 5 of the bag cage. Multiple transverse support members 3 are distributed along the circumferential direction and fixedly connected to the longitudinal main ribs 2.

[0030] like Figure 2As shown, the transverse support member 3 of the bag cage includes a bent portion and a support portion 35. The bent portion includes multiple sets of interconnected "M"-shaped connectors. The support portion 35 can improve the overall strength of the transverse support member 3 of the bag cage and improve the stability of the overall bag cage structure. The support portion 35 is preferably circular, but other shapes can also be used.

[0031] In this embodiment, as Figure 2 As shown, the bent portion of the transverse support member 3 of the bag cage is made of iron sheet. The bent portion made of iron sheet has good bending resistance, is convenient for bending production, and does not affect the overall strength and stability.

[0032] In this embodiment, as Figure 2 As shown, the "M"-shaped connector includes a first connector 31, a second connector 32, a third connector 33, and a fourth connector 34, which are connected end-to-end in sequence. The first connector 31, second connector 32, third connector 33, and fourth connector 34 are interconnected to form an "M"-shaped connector structure. This "M"-shaped connector structure is more stable. Due to the special design of the M-shaped bag cage with its large and small pleats, it can fully ensure that the filter bag is easier to clean, has higher cleaning efficiency, and lower dust removal resistance.

[0033] In this embodiment, it is further preferred that, for example Figure 2 As shown, the joint between the third connector 33 and the fourth connector 34 is at a certain distance from the support portion 35. This distance reduces the material used in the connectors, thus reducing their weight, without affecting the overall strength and support effect.

[0034] In this embodiment, as Figure 2 As shown, the joints between the first connector 31 and the third connector 33, and between the second connector 32 and the fourth connector 34, are fixedly connected to the longitudinal main reinforcement 2 of the bag cage. The specific number of joints can be determined by... Figure 2 The structure consists of 6 groups of 12 folds, meaning there are 12 longitudinal main reinforcing bars 2 in the bag cage. In this embodiment, the number of bends is not limited to 12 folds; any number of 3 groups of 6 folds or more can also be used, meaning the bag cage has 6 or more vertical reinforcing bars in any form.

[0035] In this embodiment, in order to support the external longitudinal main reinforcement 2 of the bag cage, the transverse support 3 of the bag cage is installed inside the longitudinal main reinforcement 2 of the bag cage.

[0036] In this embodiment, in order to further provide support, the transverse support 3 of the bag cage is installed perpendicularly to the longitudinal main reinforcement 2 of the bag cage.

[0037] In this embodiment, such as Figure 1 As shown, multiple transverse support members 3 of the bag cage are installed at even intervals along the length direction of the longitudinal main reinforcement 2 of the bag cage.

[0038] In this embodiment, the spacing between adjacent transverse support members 3 of the bag cage is further optimized to be 100-300mm.

Multiple transverse support members 3 are distributed along the circumferential direction and fixedly connected to the longitudinal main ribs 2.

[0041] like Figure 4 As shown, the transverse support member 3 of the bag cage includes a bent portion and a support portion 35. The bent portion includes multiple sets of interconnected "M"-shaped connectors. The support portion 35 can improve the overall strength of the transverse support member 3 of the bag cage and improve the stability of the overall bag cage structure. The support portion 35 is preferably circular, but other shapes can also be used.

[0042] In this embodiment, as Figure 4 As shown, the bent portion of the transverse support member 3 of the bag cage is made of iron wire. The bent portion made of iron wire has good bending resistance, is convenient for bending production, and has better overall strength and stability.

[0043] In this embodiment, as Figure 4 As shown, the "M"-shaped connector includes a first connector 31, a second connector 32, a third connector 33, and a fourth connector 34, which are connected end-to-end in sequence. The first connector 31, second connector 32, third connector 33, and fourth connector 34 are interconnected to form an "M"-shaped connector structure. This "M"-shaped connector structure is more stable. Due to the special design of the M-shaped bag cage with its large and small pleats, it can fully ensure that the filter bag is easier to clean, has higher cleaning efficiency, and lower dust removal resistance.

[0044] In this embodiment, it is further preferred that, for example Figure 4As shown, the joint between the third connector 33 and the fourth connector 34 is at a certain distance from the support portion 35. This distance between the joint between the third connector 33 and the fourth connector 34 and the support portion 35 indicates that the M-shaped bag cage is primarily used to support the M-shaped pleated filter bag, ensuring that the pleats of the M-shaped pleated filter bag do not overlap and affect the effective filtration area of ​​the filter bag.

[0045] In this embodiment, as Figure 4 As shown, the joints between the first connector 31 and the third connector 33, and between the second connector 32 and the fourth connector 34, are fixedly connected to the longitudinal main reinforcement 2 of the bag cage. The specific number of joints can be determined by... Figure 4 The structure consists of 6 groups of 12 folds, meaning there are 12 longitudinal main reinforcing bars 2 in the bag cage. In this embodiment, the number of bends is not limited to 12 folds; any number of 3 groups of 6 folds or more can also be used, meaning the bag cage has 6 or more vertical reinforcing bars in any form.

[0046] In this embodiment, in order to support the external longitudinal main reinforcement 2 of the bag cage, the transverse support 3 of the bag cage is installed inside the longitudinal main reinforcement 2 of the bag cage.

[0047] In this embodiment, in order to further provide support, the transverse support 3 of the bag cage is installed perpendicularly to the longitudinal main reinforcement 2 of the bag cage.

[0049] In this embodiment, the spacing between adjacent transverse support members 3 of the bag cage is further optimized to be 100-300mm.

[0050] The bag cage structure of this utility model of bag dust collector adopts a new type of bag cage transverse support structure, which makes the support more secure, lighter in weight, more stable overall, lower in dust removal resistance, and higher in dust removal efficiency.
