Description

Technical Field

[0001] This utility model relates to the technical field of baghouse dust collectors, specifically a baghouse dust collector for machining. Background Technology

[0002] A baghouse dust collector is a dry dust collection device that filters dust-laden gas through filter bags to separate solid particles from the gas. In a baghouse dust collector, larger dust particles impact the filter bag surface due to inertia or settle into the ash hopper due to gravity, while finer dust particles are carried by the airflow through the filter bags and captured by the filter bag's fiber layer. The filter bags are typically made of woven or non-woven felt and effectively capture fine dust. As filtration progresses, the dust layer on the filter bag surface gradually thickens; this layer, called the filter cake, improves dust collection efficiency but also increases airflow resistance. When the resistance reaches a certain level, a cleaning system (such as reverse blowing or pulse jet cleaning) is needed to remove the dust from the filter bags to restore the dust collector's filtration performance. Baghouse dust collectors are characterized by high dust collection efficiency, large air volume handling capacity, simple structure, and stable operation, and are widely used in dust control and air purification in various industries such as power, chemical, building materials, food, and pharmaceuticals.

[0003] Patent application CN202223519057.1 discloses a baghouse dust collector, which "includes a baghouse dust collector body, with a dust inlet pipe fixedly installed on the left side of the baghouse dust collector body and an air guide pipe fixedly connected to the right side of the baghouse dust collector body." This utility model utilizes the cooperation between the baghouse dust collector body, cleaning device, servo motor, and top cover. By using the rotation of the cleaning brush in the cleaning device on the inner wall of the baghouse dust collector body, it achieves the cleaning effect of removing dust adhering to the inner wall of the baghouse dust collector body, effectively solving the problem of manual cleaning and employing mechanical cleaning. This method replaces manual cleaning, reducing the workload of staff, reducing the amount of dust inhaled by staff, and also reducing the damage caused by dust to the bag filter body, thus extending the service life of the bag filter body. Based on the above patent search, and combined with the existing technology of bag filters for machining, it was found that when bag filters are used, the cleaning effect of bag filters is not good, and dust blockage occurs. Over time, the filter bags will be severely worn, especially since some dust sticks to the filter bags, which is difficult to remove. Subsequent manual disassembly and cleaning or replacement is required, which is time-consuming, labor-intensive, and very complicated.

[0004] Based on this, this utility model designs a bag filter for machining to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-9In this embodiment of the utility model, a bag filter for machining includes a support column 1. A bag filter body 2 is fixedly installed on the upper end of the support column 1. Bags 3 are installed inside the bag filter body 2. A dust removal mechanism 4 is arranged at the rear of the bag filter body 2, and a displacement mechanism 5 is arranged at the front of the bag filter body 2. The dust removal mechanism 4 includes a connecting horizontal plate 401, striking rods 402, a mounting plate 403, and a vibration motor 404. Multiple bags 3 are distributed from left to right inside the bag filter body 2. A connecting horizontal plate 401 is arranged on the outer side of the bags 3. Striking rods 402 are fixedly installed on the inner wall of the connecting horizontal plate 401. A mounting plate 403 is fixedly installed at the rear end of the connecting horizontal plate 401. A vibration motor 404 is fixedly installed on the mounting plate 403. Multiple striking rods 402 are arranged from left to right. The dust collector 4 is mounted on the connecting horizontal plate 401. A striking rod 402 is provided between every two sets of filter bags 3. The dust removal mechanism 4 also includes a first chamber 405, a connecting plate 406, a limiting telescopic rod 407, a first limiting rail 408, and a limiting slider 409. The first chamber 405 is fixedly installed at the rear end of the filter bag dust collector body 2. The first limiting rail 408 is fixedly installed at both the left and right ends of the first chamber 405. A limiting slider 409 is provided inside the first limiting rail 408. The limiting slider 409 is fixedly installed at both the left and right ends of the mounting plate 403. The limiting slider 409 is slidably connected to the first limiting rail 408. The connecting plate 406 is fixedly installed at the rear end of the limiting slider 409. The limiting telescopic rod 407 is fixedly installed at the lower end of the connecting plate 406. The limiting telescopic rod 407 is fixedly installed at the bottom end of the first chamber 405.

[0031] See Figure 6 and Figure 8 Initially, before activating this dust removal mechanism 4, the vibration motor 404 needs to be powered on and connected to the control terminal. When activating, simply start the vibration motor 404. The vibration motor 404 then drives the connecting horizontal plate 401 and the striking rod 402 to vibrate at high frequency. The striking rod 402 is located between each pair of filter bags 3 and can contact the filter bags 3 directly. The high-frequency vibration can effectively shake off the dust on the filter bags 3, especially for dust that is not very sticky or is relatively dry, thereby achieving a high-efficiency dust removal effect and avoiding some stubborn dust.

[0032] Among them, the dust removal mechanism 4 adopts an automatic tapping structure, which, together with the high-frequency vibration of the vibration motor 404, can knock multiple filter bags 3 in a unified manner, thereby quickly knocking the dust off the filter bags 3 and sinking them into the dust collection bin, effectively improving the efficiency of cleaning dust from the dust bags of this dust collector. In addition, the dust collector itself is also equipped with a pulse cleaner. The addition of the dust removal mechanism 4 can optimize the treatment of some stubborn dust. The high-frequency vibration can effectively shake off the dust on the filter bags 3, especially for those dusts that are not very sticky or are relatively dry.

[0033] The displacement mechanism 5 includes a drive motor 505, a drive rod 506, and a transmission belt 507. The drive rod 506 is fixedly installed at the transmission end of the drive motor 505, and the transmission belt 507 is provided on the outside of the drive rod 506. The displacement mechanism 5 also includes a second chamber 501, a second limiting rail 502, a limiting slide plate 503, a motor bracket 504, and a fixing plate 508. The drive motor 505 is fixedly installed on the motor bracket 504. The second chamber 501 is fixedly installed at the front end of the bag filter body 2. The motor bracket 504 is fixedly installed at the front end of the second chamber 501. The second limiting rail 502 is fixedly installed at the right end inside the second chamber 501. The limiting slide plate 503 is slidably connected inside the second limiting rail 502. The limiting slide plate 503 is fixedly installed at the front end of the connecting horizontal plate 401. The fixing plate 508 is provided on the left side of the limiting slide plate 503. The connecting horizontal plate 401 is connected to the transmission belt 507 through the fixing plate 508.

[0034] See Figure 6 , Figure 7 , Figure 8 and Figure 9 Before activation, the drive motor 505 needs to be powered on and connected to the control terminal. It is necessary to ensure that the dust removal mechanism 4 has started the vibration dust removal operation. When activated, the drive motor 505 is started to drive the drive rod 506 and the transmission belt 507 to rotate. When the transmission belt 507 rotates, it will drive the fixed plate 508 and some parts such as the connecting horizontal plate 401, the striking rod 402, the mounting plate 403 and the vibration motor 404 at the rear end of the fixed plate 508 to move up and down, thereby expanding the cleaning range of the dust removal mechanism 4.

[0035] The displacement mechanism 5 adopts an electric drive belt-guided structure. The displacement mechanism 5 complements the dust removal mechanism 4 and can drive the connecting horizontal plate 401, striking rod 402, mounting plate 403 and vibration motor 404 and other components in the dust removal mechanism 4 to move up and down, thereby directly beating most of the area of ​​the bag body 3, effectively expanding the dust removal range of the dust removal mechanism 4, and ensuring the stability and reliability of the dust removal of the bag body 3.

[0036] The working principle of this utility model is as follows: First, multiple filter bags 3 are installed inside the bag filter body 2, which is fixedly installed by the support column 1, for capturing and filtering dust in the air. A dust removal mechanism 4 is provided at the rear of the filter body. This mechanism includes a connecting horizontal plate 401, a striking rod 402, a mounting plate 403, and a vibration motor 404. After the vibration motor 404 is started, it transmits power through the connecting horizontal plate 401, causing the striking rod 402 to vibrate at high frequency, thereby striking the filter bags 3 and shaking off the dust adhering to the bags. Simultaneously, to improve the cleaning effect, the dust removal mechanism 4 also includes a first chamber 405, a connecting plate 406, a limiting telescopic rod 407, a first limiting rail 408, and a limiting slider 409. These components work together to ensure that the striking rod 402 vibrates in an orderly manner and prevents excessive displacement of the mechanism during vibration. Furthermore, the design of the displacement mechanism 5 further enhances the cleaning efficiency of the dust collector. The force and displacement mechanism 5 includes a drive motor 505, a drive rod 506, a transmission belt 507, a second chamber 501, a second limit rail 502, a limit slide plate 503, a motor bracket 504, and a fixing plate 508. When the drive motor 505 starts, the transmission belt 507 rotates, driving the connecting horizontal plate 401 and its rear-end striking rod 402, mounting plate 403, and vibration motor 404 to move up and down through the fixing plate 508. This allows most of the bag body 3 to be beaten, improving dust removal efficiency. The entire system, through automatic beating and electrically driven belt guidance, achieves comprehensive cleaning of the bag body 3, effectively solving the problems of poor cleaning effect, dust blockage, and bag wear in traditional bag dust collectors. Through the combined action of the vibration motor 404 and the displacement motor, this bag dust collector can quickly knock dust down and settle into the dust collection chamber, ensuring the high efficiency and stability of the dust collector in cleaning the dust bag.
