Description

Technical Field

[0001] The utility model relates to a frameless filter bag anti-deformation structure, belonging to the technical field of dust filtering equipment. Background Art

[0002] The dust filtering equipment is equipped with a frameless filter bag. There is no supporting frame inside and outside the filter bag. The filter bag has low cost and is very convenient to maintain and replace. However, there are the following defects in actual application:

[0003] 1. Since the filter bag is made of filter cloth, it is not strong enough and has extensibility. When it is installed, it is tightened to form a concave drum shape. When the suction nozzle rotates to suck dust, it is easy to stir the filter bag, causing damage to the filter bag.

[0004] 2. When the dust filter equipment is running, the external main fan is turned on, and the dust-laden airflow enters the filter bag from the bag opening. The short-lint dust is blocked and adheres to the inner surface of the filter bag. After filtration, the airflow passes through the filter bag and flows out from the outer surface, forming a pressure difference between the inside and outside of the filter bag. As the short-lint dust accumulates on the inner surface of the filter bag, the dust filtration resistance of the filter bag increases, and the pressure difference between the inside and outside increases. The filter bag forms a serious convex waist drum shape, which makes it difficult for the suction nozzle to completely absorb the short-lint dust attached to the inner surface of the filter bag, thus forming a vicious cycle. Summary of the Invention

[0005] The technical problem to be solved by the utility model is to provide a skeleton-free filter bag anti-deformation structure for the above-mentioned existing technology. The structure is simple and the installation is convenient. The deformation of the filter bag is controlled within a certain range, and the filter bag is prevented from forming serious concave waist drum shape and convex waist drum shape, thereby improving the service life of the filter bag.

[0006] The technical solution adopted by the present invention to solve the above-mentioned problem is: a frameless filter bag anti-deformation structure, including a filter bag, which lies horizontally between a front bracket and a rear bracket, one end of the filter bag is fixed to the mounting ring of the front bracket, and the other end of the filter bag is fixed to the sealing plate of the rear bracket, and a plurality of anti-deformation units are provided on the periphery of the filter bag, and the plurality of anti-deformation units are arranged at intervals along the axis of the filter bag to control the deformation of the filter bag.

[0007] Any of the anti-deformation units includes a positioning ring, which is sleeved on the filter bag. The positioning ring and the filter bag are fixedly connected via a fixing piece.

[0008] The fixing member includes a plurality of buckle belts, and the plurality of buckle belts are evenly distributed along the outer circumference of the positioning ring.

[0009] Compared with the existing technology, the advantages of the utility model are: a frameless filter bag anti-deformation structure with simple structure and easy installation. The filter bag is fixed to the positioning ring by a buckle, so that the deformation of the filter bag is controlled within a certain range, preventing the filter bag from producing serious concave waist drum shape and convex waist drum shape, thereby improving the service life of the filter bag.

[0013] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 As shown, this embodiment shows a frameless filter bag anti-deformation structure comprising a frameless filter bag 4, which lies horizontally between a front support 1 and a rear support 5. One end of the filter bag 4 is secured to a mounting ring 2 of the front support, and the other end is secured to a sealing plate 6 of the rear support. Multiple positioning rings 3 are provided around the outer periphery of the filter bag, spaced apart along the axial direction of the filter bag and fixedly connected to the filter bag via fixings. This controls deformation of the filter bag within a certain range and prevents the filter bag from developing a severe concave or convex waist drum shape.

[0015] like Figure 2 As shown, the fixing member includes a plurality of buckles 7, which are evenly distributed along the outer circumference of the positioning ring, and the buckles fix the filter bag and the positioning ring together.

[0016] The present application has a simple structure and is easy to install. The filter bag is fixed to the positioning ring by a buckle, so that the deformation of the filter bag is controlled within a certain range, preventing the filter bag from forming a serious concave waist drum shape or a convex waist drum shape, thereby improving the service life of the filter bag.

[0017] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
