Description

Technical Field

[0001] This utility model belongs to the field of dust removal technology, and more specifically, relates to an M-type pleated cloth bag adapted to a dust collector bag cage. 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] Existing baghouse dust collectors typically use circular filter bags that fit over the outside of the bag cage. This traditional circular filter bag design results in a small filtration area and makes cleaning difficult, thus affecting the filtration efficiency. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an M-type pleated filter bag, which can increase the filtration performance of the bag filter dust collector. It changes the traditional round filter bag used in the dust collector to a pleated filter bag with alternating sizes, increasing the filtration area by 50%-100% while keeping the filter bag diameter unchanged.

[0005] Technical solution: The present invention relates to an M-shaped pleated cloth bag, comprising a bag body, one end of which is connected to a clamp structure, and the other end of which is a sealed bottom of the bag. The bag body adopts a pleated structure.

[0006] In some embodiments, the bag body is made of fabric or felt woven from synthetic fibers, natural fibers, or glass fibers.

[0007] In some embodiments, the bag body adopts an "M"-shaped pleated structure.

[0008] In some embodiments, the bag body includes three or more sets of interconnected "M"-shaped pleated structures.

[0009] In some embodiments, a fixing hoop is provided on the outer side of the bag body.

[0010] In some embodiments, the fixing hoops are arranged at equal intervals along the length direction.

[0011] In some embodiments, the bag body, the clamp structure, and the bottom of the bag cage are all connected by sewing or heat fusion.

[0012] In some embodiments, the bag body is adapted to an M-shaped bag cage support structure.

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

[0014] (1) In order to save the manufacturing and operating costs of bag dust collectors and increase the filtration performance of bag dust collectors, the traditional round filter bags used in the dust collectors are changed to "M" shaped pleated bags with alternating sizes. While ensuring that the filter bag diameter remains unchanged, the filtration area is increased by 50%-100%.

[0015] (2) The M-type pleated bag increases the filtration area on the basis of the traditional round bag. The proportion of each pleat is further optimized in the pleat structure. The two adjacent pleats are of different sizes to form an M-type structure, so that there is no overlap between the pleats, thus ensuring the effective application of the filter bag filtration area.

[0016] (3) The special structure of the M-type pleated filter bag with alternating large and small pleats can make the airflow distribution in the dust collector more uniform, making the filter bag cleaning easier and more efficient, and reducing the operating resistance of the dust collector.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 and Figure 2 As shown, an M-shaped pleated cloth bag includes a bag body 1, one end of which is connected to a clamp structure 3, and the other end of which is connected to a sealed bag bottom 2. The bag body 1 adopts a pleated structure.

[0025] The M-shaped pleated cloth bag of this utility model is directly installed on the outside of the bag cage and is structurally adapted to the M-shaped support member inside the bag cage. The clamp structure 3 is connected to the top of the bag cage.

[0026] In this embodiment, the bag body 1 is preferably made of fabric or felt woven from synthetic fibers, natural fibers or glass fibers.

[0027] In this embodiment, as Figure 2 As shown, the bag body 1 adopts an "M"-shaped pleated structure 21. More preferably, the bag body 1 includes three or more sets of interconnected "M"-shaped pleated structures 21.

[0028] This utility model utilizes an "M"-shaped pleated structure in its filter bag, thereby increasing the filtration performance of the baghouse dust collector. It replaces the traditional round filter bag with a pleated one, increasing the filtration area by 50%-100% while maintaining the same filter bag diameter. Furthermore, the M-shaped pleated filter bag increases the filtration area compared to the traditional round bag by optimizing the proportions of each pleat. Adjacent pleats are arranged in an M-shape with one large and one small pleat, preventing overlap and ensuring effective utilization of the filter bag's filtration area.

[0029] In addition, the special structural form of the "M"-shaped pleats, with alternating large and small pleats, is as follows: Figure 2 As shown, this can make the airflow distribution inside the dust collector more uniform, make the filter bag cleaning easier and more efficient, and reduce the operating resistance of the dust collector.

[0030] In this embodiment, as Figure 2 As shown, a fixing band 22 is provided on the outer side of the bag body 1. More preferably, the fixing band 22 is spaced apart along the length direction. The fixing band 22 serves to maintain the "M" shaped pleats of the bag and also to fix the bag in place.

[0031] In this embodiment, the bag body 1, the clamp structure 3, and the sealed bag bottom 2 are all detachably connected. By using sewing or heat fusion to connect the bag body 1, the clamp structure 3, and the bag bottom 2, it is more time-saving and labor-saving to replace the bag, thus improving efficiency.

[0032] In this embodiment, the bag body 1 is adapted to the bag cage support structure. The specific bag structure corresponds to the specific "M"-shaped support structure of the bag cage. This increases the dust removal area while allowing for a closer fit between the bag and the bag cage, resulting in a more uniform airflow distribution within the dust collector's housing. This makes bag cleaning easier and more efficient, and reduces the operating resistance of the dust collector.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
