Description

Technical Field

[0001] The invention relates to the field of dust removal bags, and in particular to a dust removal bag assembly with a keel supporting structure. Background Art

[0002] The bag filter is a dry dust filter component suitable for capturing fine, dry and non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt. It uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag filter, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] The inner wall of the traditional dust bag is easy to adhere to dust particles. After long-term use, the wind pressure squeezes the fine dust particles attached to the inner wall of the bag, which reduces the efficiency of the dust collector. To address the above problems, a Chinese patent provides a bag dust collector with an auxiliary vibration structure (publication number: CN107866114A), which is driven by a rotating shaft through a vibration device, and the dust removal devices on both sides are struck by a striking block, so that the dust adsorbed on the inner wall of the filter bag falls;

[0004] However, in the actual use of the above technical solution, dust gradually accumulates in the bag. Since there are gaps between the dust, the dust carrying capacity of the bag is reduced, which undoubtedly shortens the replacement cycle of the bag and makes it difficult to deal with the dust in the bag in time while removing dust.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] The object of the present invention is to provide a dust bag assembly with a keel support structure to solve the technical defects proposed by the background technology.

[0007] The purpose of the present invention can be achieved by the following technical solution: a dust bag assembly with a keel support structure, comprising a bag body, an air inlet is opened on the top of the bag body, a fixed keel is fixedly installed inside the bag body, and a processing assembly is fixedly installed in the fixed keel;

[0008] The processing assembly includes a fixed block, a movable plate and an extrusion plate, wherein the fixed block is fixedly installed in the fixed keel, the movable plate is movably installed on the fixed block, and the extrusion plate is movably installed under the fixed block;

[0009] The processing assembly also includes a connecting rod and a connecting block. The connecting block is fixedly installed on the inner wall of the bag body.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1 - Figure 6 As shown, this embodiment is a dust bag assembly with a keel supporting structure, including a bag body 1, an air inlet 101 is opened on the top of the bag body 1, a fixed keel 102 is fixedly installed inside the bag body 1, a processing assembly 2 is fixedly installed in the fixed keel 102, and the processing assembly 2 includes a fixed block 201 and a movable plate 202, and the fixed block 201 is fixedly installed in the fixed keel 102.

[0031] The movable plate 202 is movably mounted on the fixed block 201, and a horizontal bar 214 is fixedly mounted on the outer circumference of the fixed block 201. The horizontal bar 214 is fixedly connected to the fixed keel 102. The processing component 2 also includes a connecting rod 204 and a connecting block 205. The connecting block 205 is fixedly mounted on the inner wall of the bag body 1. One end of the connecting rod 204 is movably connected to the movable plate 202, and the end of the connecting rod 204 away from the movable plate 202 is fixedly connected to the connecting block 205.

[0032] A fixed tube 206 is fixedly installed on the fixed block 201, and a moving rod 207 is movably installed inside the fixed tube 206. The top of the moving rod 207 is fixedly connected to the moving plate 202. A spring is sleeved on the moving rod 207, and both ends of the spring are fixedly connected to the moving plate 202 and the fixed tube 206 respectively. A bellows is fixedly installed outside the fixed tube 206, and the fixed tube 206 and the moving rod 207 are shielded by the bellows to prevent dust from entering the moving rod 207 and affecting the movement of the moving plate 202. When the gas contacts the moving plate 202, the moving plate 202 moves downward under the action of wind, and the spring is gradually compressed at this time.

[0033] When the movable plate 202 moves a certain distance, the spring force gradually becomes greater than the wind force. At this time, under the action of the spring, the movable plate 202 is pushed upward. When the spring force is less than the wind force, the movable plate 202 moves downward again. During the dust removal process, the movable plate 202 reciprocates inside the bag body 1.

[0034] A connecting groove 208 is opened on the movable plate 202, and a cross bar 209 is fixedly installed in the connecting groove 208. A rotating block 210 is movably installed on the cross bar 209. The rotating block 210 is fixedly connected to the connecting rod 204. When the movable plate 202 reciprocates up and down, the rotating block 210 rotates on the cross bar 209, and the connecting rod 204 is pulled to move by the rotating block 210, and then the connecting block 205 is pulled by the connecting rod 204.

[0035] There are multiple connecting grooves 208, which are evenly spaced on the movable plate 202. Multiple guide rods 211 are fixedly installed on the bottom of the movable plate 202. The cross-section of the movable plate 202 is a trapezoid with a small top and a large bottom. The setting of the movable plate 202 with a small top and a large bottom ensures that the gas can be evenly diffused to the surroundings after contacting the movable plate 202, avoiding the gas from directly hitting the bag body 1, thereby reducing the risk of the bag body 1 falling off.

[0036] When gas and dust enter the bag body 1 from the air inlet 101, they first hit the movable plate 202. Under the action of wind, the movable plate 202 moves downward, and the movable plate 202 drives the connecting rod 204 to move downward. Under the action of the connecting rod 204, the connecting block 205 is pushed to both sides. When the movable plate 202 is reset, it gradually moves upward, and the connecting block 205 is pulled to the center of the bag body 1 by the connecting rod 204. The above steps are repeated to drive the bag body 1 to vibrate back and forth, so that the dust attached to the inner wall of the cloth bag falls off, and the cloth bag is effectively cleaned.

[0037] Example 2: Please refer to Figure 7 As shown, the present invention also includes an extrusion plate 203, which is movably installed below the fixed block 201, and a vertical rod 212 is fixedly installed on the top of the extrusion plate 203. One end of the guide rod 211 away from the movable plate 202 is movably installed in the vertical rod 212, and a reset block 213 is movably installed in the vertical rod 212. The reset block 213 is fixedly connected to the guide rod 211, and a spring is fixedly installed at the bottom of the reset block 213, and the other end of the spring is fixedly connected to the inner wall of the vertical rod 212. Three guide rods 211 are arranged, and the guide rods 211 are evenly spaced on the fixed block 201. The guide rods 211 are movably connected to the fixed block 201. In the process of the movable plate 202 driving the extrusion plate 203 to move, the stability of the movable plate 202 is effectively guaranteed by the arranged guide rods 211.

[0038] The extrusion plate 203 is provided with a plurality of through grooves, which are located between the vertical rods 212. When the movable plate 202 drives the extrusion plate 203 to move upward, the dust on the extrusion plate 203 falls from the through grooves on the extrusion plate 203. When the extrusion plate 203 moves downward, the dust accumulated at the bottom of the bag body 1 is squeezed. As the dust accumulates, the dust thickness at the bottom of the bag body 1 gradually increases. At this time, the guide rod 211 moves in the vertical rod 212, and the spring is gradually compressed. Through the elastic force of the spring, the extrusion plate 203 always applies a certain pressure to the dust at the bottom of the bag body 1, thereby ensuring the stability of the internal dust during the filtering process of the bag body 1.

[0039] When the movable plate 202 moves downward, it drives the squeezing plate 203 to move downward synchronously. When the movable plate 202 moves upward, it pulls the squeezing plate 203 to move upward, thereby driving the bag body 1 to vibrate and periodically squeezing the dust at the bottom of the bag body 1, thereby compressing the dust, effectively improving the utilization rate of the internal space of the bag body 1, and at the same time making the dust tightly connected for easy subsequent processing.

[0040] Combining the first and second embodiments, it can be known that the up and down reciprocating motion of the movable plate 202 drives the connecting rod 204 to pull the connecting block 205 to do reciprocating motion, thereby driving the bag body 1 to vibrate back and forth, so that the dust attached to the inner wall of the bag falls off, and the bag is effectively cleaned. At the same time, during the movement of the movable plate 202, the squeezing plate 203 is driven to reciprocate up and down, so as to periodically squeeze the dust at the bottom of the bag body 1, realize the compression of the dust, and effectively improve the utilization rate of the internal space of the bag body 1.

[0041] The working process and principle of the present invention are as follows:

[0042] First, by setting the movable plate 202 and the connecting rod 204, the movable plate 202 reciprocates up and down, driving the connecting rod 204 to pull the connecting block 205 to reciprocate, thereby driving the bag body 1 to vibrate back and forth, so that the dust attached to the inner wall of the bag falls off, and the bag is effectively cleaned;

[0043] Furthermore, by providing the moving plate 202 and the squeezing plate 203, the moving plate 202 moves, driving the squeezing plate 203 to reciprocate up and down, thereby periodically squeezing the dust at the bottom of the bag body 1, thereby compressing the dust and effectively improving the utilization rate of the internal space of the bag body 1;

[0044] In summary, while cleaning the inner wall of the bag, the dust is also compressed.
