Description

Technical Field

[0001] The utility model relates to the technical field of dust filter bags, and particularly relates to a leak-proof structure of a dust filter bag. Background Technique

[0002] The dust filter bag is a key part in the operation of a bag filter. Usually, a cylindrical filter bag is vertically suspended in the dust collector. The fabric and design of the filter bag should strive for efficient filtration, easy dust stripping, and long durability.

[0003] When the ports of the existing filter cartridge dust bags are docked, due to the poor sealing performance of the docking device, leakage often occurs after docking. Due to the gravity of the dust, it leaks out from the gap between the filter cartridge and the dust bag, causing great damage to the machine body. When leakage occurs, it is generally repaired by the method of secondary gluing, and it is not easy to handle the dust leakage, which has limitations in use.

[0004] The existing patent (Publication No.: CN211799456U) a leak-proof structure for the port of a filter cartridge dust bag, including a fixing ring, a shaping ring and a filter cartridge. The top of the fixing ring is fixedly installed with a shaping ring through bolts, and the bottom of the shaping ring is fixedly installed with a filter cartridge through bolts. An annular groove is arranged in an open manner above the fixing ring. A fixing clamp is arranged on the outer side of the filter cartridge. One end of the fixing clamp is rotatably connected with a movable clamp through a rotating shaft. Fixing holes are arranged in an open manner at the right ends of the fixing clamp and the movable clamp. A long bolt is movably connected inside the fixing hole. Embedding plates are fixedly installed at the bottoms of the fixing clamp and the movable clamp through bolts. A rubber sleeve is closely attached to the outer side of the embedding plate. A dust filter bag is fixedly arranged inside the filter cartridge. This kind of leak-proof structure for the port of the filter cartridge dust bag has stronger environmental adaptability and tightness, reducing the later maintenance cost.

[0005] In view of the above problems, the existing patent gives a solution, but it lacks a structure for flexible adjustment when fixing the port of the dust filter bag, resulting in a reduction in the flexibility of the dust filter bag to adapt to different working conditions.

[0006] Therefore, a leak-proof structure of a dust filter bag is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a leak-proof structure of a dust filter bag, which can solve the problem that the existing dust filter bag lacks a structure for flexible adjustment when fixing the port of the dust filter bag, resulting in a reduction in the flexibility of the dust filter bag to adapt to different working conditions.

[0008] To achieve the above purpose, the utility model provides the following technical solution: a leak-proof structure of a dust filter bag, including a dust filter bag body, a leak-proof mechanism is welded at the top of the dust filter bag body, and a fixing mechanism is bolted at the top of the dust filter bag body;

[0009] The anti-leakage mechanism includes a metal frame, a dust-proof cloth, a strap, and a pull ring. The metal frame is welded to the top of the dust filter bag body. The dust-proof cloth is sleeved on the surface of the metal frame. The strap is movably connected to the inner side of the dust-proof cloth. The pull ring is fixedly connected to the surface of the strap.

[0010] Preferably, the fixing mechanism includes an electric telescopic rod, a limit ring, an electromagnet, a guide post, and a stop piece. The electric telescopic rod is bolted to the top of the dust filter bag body.

[0011] Preferably, the limit ring is bolted to the top of the electric telescopic rod, and the electromagnet is bolted to the inner side of the limit ring.

[0012] Preferably, the guide post is bolted to the top of the dust filter bag body. The top of the guide post penetrates through the inner side of the limit ring, and the stop piece is welded to the top of the guide post.

[0013] Preferably, a buffer pad is sleeved on the top of the limit ring, and an anti-corrosion coating is applied to the surface of the buffer pad.

[0014] Preferably, the adsorption surface of the electromagnet is engraved with anti-slip lines, and the electromagnet is circular.

[0015] Preferably, the metal frame is annular and made of stainless steel.

[0016] Preferably, the dust-proof cloth is made of non-woven fabric material and coated with waterproof paint.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. The filter dust bag body of the present application can support and limit the anti-leakage mechanism and the fixing mechanism.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0028] A dust filter bag anti-leakage structure includes a dust filter bag body 1, an anti-leakage mechanism 2 is welded to the top of the dust filter bag body 1, and a fixing mechanism 3 is bolted to the top of the dust filter bag body 1;

[0029] The anti-leakage mechanism 2 includes a metal frame 201, a dust-proof cloth 202, a drawstring 203, and a pull ring 204. The metal frame 201 is welded to the top of the dust filter bag body 1, the dust-proof cloth 202 is sleeved on the surface of the metal frame 201, the drawstring 203 is movably connected to the inner side of the dust-proof cloth 202, and the pull ring 204 is fixedly connected to the surface of the drawstring 203.

[0030] In this embodiment: By setting the dust filter bag body 1, the anti-leakage mechanism 2 and the fixing mechanism 3 can be supported and limited. By setting the metal frame 201, support is provided for the dust-proof cloth 202 to maintain its shape, ensuring that the dust-proof cloth 202 can effectively cover and protect the top opening of the dust filter bag, enhancing the stability of the overall structure, and can provide an adsorption force for the electromagnet 303. By setting the dust-proof cloth 202, dust leakage from the port connection of the dust filter bag body 1 is blocked. Its soft material can adapt to different shapes and interfaces, increasing the anti-leakage coverage area and flexibility. By setting the drawstring 203, by adjusting the tightness of the drawstring 203, the mouth can be closed more tightly, improving the anti-leakage effect and adapting to different sizes and filling levels. By setting the pull ring 204, it is convenient for the user to operate the drawstring 203, making the tightening and loosening of the drawstring 203 more convenient.

[0031] Specifically, as Figure 3 , Figure 4 , Figure 5 shown, the fixing mechanism 3 includes an electric telescopic rod 301, a limit ring 302, an electromagnet 303, a guide post 304, and a retaining piece 305. The electric telescopic rod 301 is bolted to the top of the dust filter bag body 1.

[0032] Specifically, as Figure 3 , Figure 4 , Figure 5 shown, the limit ring 302 is bolted to the top of the electric telescopic rod 301, and the electromagnet 303 is bolted to the inner side of the limit ring 302.

[0033] Specifically, as Figure 3 、 Figure 4 shown, the guide post 304 is bolted to the top of the dust filter bag body 1. The top of the guide post 304 penetrates through the inside of the limit ring 302, and the baffle 305 is welded to the top of the guide post 304.

[0034] In this embodiment: By setting the electric telescopic rod 301, the position of the limit ring 302 can be adjusted to achieve precise fixation and positioning, adapting to different installation environments and working conditions. By setting the limit ring 302, it can move up and down following the electric telescopic rod 301 and drive the electromagnet 303 to move up and down. By setting the electromagnet 303, a strong adsorption force is provided to make the limit ring 302 adsorb and fit with the metal frame 201, further increasing the sealing performance at the port of the dust filter bag body 1. By setting the guide post 304, the movement direction of the electric telescopic rod 301 and the limit ring 302 is ensured to be accurate, preventing deviation and shaking. By setting the baffle 305, the guide post 304 can be prevented from disengaging from the limit ring 302, ensuring the safety and stability of the guide post 304 during operation.

[0035] Specifically, as Figure 4 、 Figure 5 shown, a buffer pad 4 is sleeved on the top of the limit ring 302, and an anti-corrosion coating is applied on the surface of the buffer pad 4.

[0036] Specifically, as Figure 3 、 Figure 5 shown, anti-slip patterns are engraved on the adsorption surface of the electromagnet 303, and the electromagnet 303 is circular.

[0037] In this embodiment: By setting the buffer pad 4, it can play a buffering role when the limit ring 302 contacts the baffle 305, reducing the impact force, protecting the limit ring 302 and the baffle 305 from being damaged by violent collisions, and extending the service life of the equipment. By setting the anti-corrosion coating, it can effectively prevent the buffer pad 4 from being corroded, ensuring that it can still normally play the buffering function in a harsh environment, and improving the durability and reliability of the buffer pad 4. By setting the anti-slip patterns, the friction between the adsorption surface of the electromagnet 303 and the adsorbed object is increased, making the adsorption more firm, preventing loosening or slipping during operation, and improving the stability of fixation. By setting the electromagnet 303 to be circular, the circular design of the electromagnet 303 makes the adsorption force distribution more uniform, reducing the situation of excessive local stress, contributing to more stable fixation of the dust filter bag, and being more convenient during installation and use, and also more smoothly cooperating with other components.

[0038] Specifically, as Figure 2 shown, the metal frame 201 is annular and made of stainless steel.

[0039] Specifically, as Figure 2 and Figure 4 shown, the dust-proof cloth 202 is made of non-woven fabric material, and the dust-proof cloth 202 is coated with waterproof paint.

[0040] In this embodiment: by setting the metal frame 201 as annular, the annular design matches the shape of the top of the dust filter bag body 1, which can provide uniform supporting force, ensure that the dust-proof cloth 202 can be stably supported in all directions, thereby improving the anti-leakage effect; by setting the metal frame 201 to be made of stainless steel, the stainless steel material has good corrosion resistance and strength, and can provide suction force for the electromagnet 303. The stainless steel material can maintain the structural stability during long-term use, is not easy to rust and deform, and extends the service life of the metal frame 201; by setting the dust-proof cloth 202 to be made of non-woven fabric material, the non-woven fabric material has good air permeability and filtering performance, can block dust leakage and does not affect air circulation, ensuring the normal progress of the filtering work; by setting the waterproof paint, the waterproof performance of the dust-proof cloth 202 can be enhanced, preventing liquid or moist dust from penetrating, and further improving the anti-leakage effect, especially performing well in a humid working environment.

[0041] Working principle: First, the user places the dust filter bag body 1 at the required working position. Then, when anti-leakage operation is needed, the user manipulates the drawstring 203 by means of the pull ring 204, adjusts the tightness of the drawstring 203, and makes the dust-proof cloth 202 close up more tightly to adapt to different fullness and sizes of the dust filter bag body 1. After that, the user turns on the power and starts the electric telescopic rod 301. After the electric telescopic rod 301 starts, it pushes the limiting ring 302 connected to it to slide along the guide post 304. Under the action of the electric telescopic rod 301, the limiting ring 302 approaches the metal frame 201, and at the same time drives the electromagnet 303 to move towards the metal frame 201. Then, the user energizes and starts the electromagnet 303. After the electromagnet 303 starts, it generates a strong adsorption force, making the limiting ring 302 and the metal frame 201 tightly adsorb and fit together. Finally, after the dust filter bag body 1 finishes working, the user turns off the electromagnet 303, starts the electric telescopic rod 301 to drive the limiting ring 302 to reset, and then restores the drawstring 203 to its initial state through the pull ring 204.

[0042] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
