Description

Technical Field

[0001] This utility model relates to the field of woodworking machinery dust removal technology, specifically to a pulse dust collector for woodworking dust removal. Background Technology

[0002] Woodworking is usually a basic production process in furniture factories. During the production process, a lot of dust of different sizes is generated. The dust mainly comes from sawing, milling, planing and sanding operations. The dust concentration is relatively high and it is harmful to human health. During the production process, a belt pulse dust collector is usually used to remove the dust. A baghouse pulse jet dust collector refers to a dust collector in which dust-laden gas enters through the inlet and passes through the filter media of the bags. Larger dust particles are captured on the surface of the bags, and the purified air is discharged from the outlet. The bags are usually made of polyester, polypropylene, or other filter materials, which can effectively intercept dust particles. As the filtration process proceeds, dust gradually accumulates on the surface of the filter bags. When the dust accumulation on the surface of the filter bags reaches a certain level, a short, high-pressure airflow is generated through the pulse valve and instantly sprayed onto the surface of the bags, peeling off the attached dust. The cleaned dust is collected in the dust hopper.

[0003] In the prior art, when cleaning dust collector bags, because the blowpipe is located at the top of the dust collector bag, the lower side of the dust collector bag is less affected by the wind, and the dust adhering to the lower surface of the dust collector bag is difficult to clean, which reduces the dust removal efficiency of the belt pulse dust collector and the service life of the dust collector bag. Based on this, this solution provides a pulse dust collector for woodworking dust removal to solve the above-mentioned problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, a pulse dust collector for woodworking is provided, which solves the problems mentioned in the background.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A pulse-jet dust collector for woodworking includes a purification chamber and support legs fixedly installed at the bottom of the purification chamber. The purification chamber contains a dust removal component for purifying air. A guide frame, fixedly connected and communicating with the purification chamber, is located on the lower side of the dust removal component. A feeding component is fixedly installed at the lower end of the guide frame. The dust removal component includes a fixed frame, a purification component, and a pulse cleaning component. The fixed frame includes a plate whose outer end is fixedly connected to the inner wall of the purification chamber. Several sets of mounting openings are provided through the plate. Several sets of purification components are provided, each corresponding to one of the sets of mounting openings. The output ends of the pulse cleaning components are respectively located on the upper side of the corresponding purification components.

[0006] Preferably, the purification component includes a mounting bracket fixedly installed on the corresponding installation port, a base plate is provided on the lower side of the mounting bracket, and a frame is fixedly connected between the mounting bracket and the base plate, with a cloth bag covering the outside of the frame.

[0007] Preferably, an air jet pipe is provided on the inner side of the frame. The upper and lower ends of the air jet pipe are rotatably connected to the mounting frame and the base plate, respectively. Several sets of air jet holes are opened through the surface of the air jet pipe. The air jet holes are evenly arranged in a ring about the central axis of the air jet pipe, and the air jet holes are inclined as a whole. The upper end of the air jet pipe is rotatably connected to the pulse cleaning assembly.

[0008] Preferably, the pulse cleaning assembly includes an air tank fixedly installed on the inner wall of the purification chamber. Several sets of pulse valves are provided on one side of the air tank. The inlet of the pulse valves is connected to the air tank, and a flange connecting plate is fixedly installed at the outlet of each set of pulse valves. A square blow pipe is fixedly installed at the lower end of the flange connecting plate. A connecting frame is fixedly connected to both ends of the square blow pipe. The connecting frame is fixedly installed on the plate. Several sets of jet connecting pipes corresponding to the installation port are fixedly installed at the lower end of the square blow pipe. The lower end of the jet connecting pipe is rotatably connected to the upper end of the jet pipe.

[0009] Preferably, the feeding assembly includes a fixed frame fixedly installed at the lower end of the guide frame, a motor rotatably installed at the front end of the fixed frame, a rotating shaft rotatably installed inside the fixed frame, a number of feeding blades fixedly installed on the rotating shaft, and the output shaft of the motor fixedly connected to one end of the rotating shaft.

[0010] Preferably, an air inlet channel is fixedly installed on the lower front side of the purification box, and an air outlet channel is fixedly installed on the upper rear side of the purification box.

[0011] Compared with the prior art, this utility model proposes a pulse dust collector for woodworking dust removal, which has the following beneficial effects: 1. In use, air containing impurities enters the purification chamber through the air inlet channel at the bottom of the dust collector via a fan. The airflow rises through the purification components, and then intercepts and adsorbs dust through the outer surface of the filter bags in the purification components. Clean air passes through the fiber gaps of the filter bags into the interior of the frame, then rises through the mounting bracket and the mounting port of the plate, and finally exits from the outlet channel at the top of the dust collector. After a period of use, a pulse valve is triggered, causing the pulse valve to open and releasing the high-pressure compressed air stored in the air tank into the corresponding square jet pipe. The high-pressure airflow enters the jet pipe through the jet connection pipe. The upper and lower mounting brackets and base plate are rotatably connected, and the jet holes on its surface are inclined. When the high-pressure airflow is ejected at high speed from the inclined jet holes, it will give the jet pipe itself a reverse torque, causing it to rotate at high speed. This causes the rotating jet pipe to blow the high-pressure airflow all-round and without dead angles onto the inner wall of the entire filter bag through its circumferentially evenly distributed inclined jet holes. This causes the filter bag to swell and shake rapidly, completely peeling off the dust cake layer attached to the outer surface of the filter bag. This effectively improves the problem of poor dust removal effect at the bottom of the dust collector bag in traditional dust removal methods, ensuring that dust on the surface of the filter bag, including the bottom side, is efficiently cleaned.

Detailed Implementation

[0013] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0014] Reference Figure 1 As shown, a pulse dust collector for woodworking includes a purification box 1 and a support leg 3 fixedly installed at the bottom of the purification box 1. The purification box 1 is equipped with a dust removal component 2 for purifying air. The lower side of the dust removal component 2 is equipped with a guide frame 4 that is fixedly connected to and communicates with the purification box 1. A feeding component 6 is fixedly installed at the lower end of the guide frame 4. Furthermore: the purification box 1 serves as the main container for dust removal, providing a sealed space for air purification to ensure the airtightness and efficiency of the dust removal process; the support leg 3 is used to stably support the entire equipment; the dust removal component 2 is responsible for filtering and capturing dust particles in the air; the guide rack 4 is used to guide the collected dust downwards; and the discharge component 6 is used to control the discharge of dust, realizing the collection and discharge of dust.

[0015] Reference Figure 2 and Figure 3 As shown, specifically in this embodiment, the dust removal component 2 includes a fixing frame 21, a purification component 22, and a pulse cleaning component 23. The fixing frame 21 includes a plate 211 whose outer end is fixedly connected to the inner wall of the purification box 1. Several sets of installation ports 212 are provided through the plate 211. Several sets of purification components 22 are provided, and they are respectively arranged inside the several sets of installation ports 212. The output end of the pulse cleaning component 23 is respectively arranged on the upper side of the corresponding purification component 22.

[0016] Furthermore: the mounting bracket 21 provides stable support for the purification component 22, facilitating the installation and maintenance of the purification component 22; the pulse cleaning component 23 is located on the upper side, optimizing the cleaning direction, effectively removing dust from the surface of the filter bag 226 in the purification component 22, extending the service life of the purification component 22, and improving dust removal efficiency.

[0017] Reference Figure 4 and Figure 5As shown, specifically, in this embodiment, the purification component 22 includes a mounting bracket 221 fixedly installed on the corresponding mounting port 212. A base plate 222 is provided on the lower side of the mounting bracket 221, and a frame 223 is fixedly connected between the mounting bracket 221 and the base plate 222. A cloth bag 226 is sleeved on the outside of the frame 223.

[0018] Furthermore: the mounting bracket 221 and the base plate 222 fix the frame 223 to form a support structure; the frame 223 maintains the shape of the filter bag 226 and prevents the filter bag 226 from collapsing, so that the opened filter bag 226 can provide high-efficiency filtration and ensure the quality of air purification.

[0019] Reference Figure 4 and Figure 5 As shown, specifically in this embodiment, an air jet pipe 224 is provided on the inner side of the frame 223. The upper and lower ends of the air jet pipe 224 are rotatably connected to the mounting frame 221 and the base plate 222, respectively. A number of air jet holes 225 are opened through the surface of the air jet pipe 224. The air jet holes 225 are evenly arranged in a ring about the central axis of the air jet pipe 224, and the air jet holes 225 are inclined as a whole. The upper end of the air jet pipe 224 is rotatably connected to the pulse cleaning assembly 23.

[0020] Furthermore, the rotating design of the two ends of the jet pipe 224, in conjunction with the inclined jet holes 225, allows the jet pipe 224 to rotate at high speed when high-pressure airflow is ejected from the inclined jet holes 225. This creates a reverse torque on the jet pipe 224, causing it to rotate at high speed. The rotating jet pipe 224, through its circumferentially distributed inclined jet holes 226, blows the high-pressure airflow in all directions and without dead angles onto the inner wall of the entire filter bag 226. This causes the filter bag 226 to inflate and shake rapidly, completely peeling off the dust cake layer adhering to the outer surface of the filter bag 226. This effectively improves the problem of poor dust removal effect at the bottom of the filter bag 226 in traditional dust removal methods, ensuring that dust on the surface of the filter bag 226, including the bottom side, is efficiently cleaned.

[0021] Reference Figure 6 As shown, specifically in this embodiment, the pulse cleaning assembly 23 includes a gas tank 231 fixedly installed on the inner wall of the purification chamber 1. Several sets of pulse valves 232 are provided on one side of the gas tank 231. The inlet of the pulse valve 232 is connected to the gas tank 231, and a flange connecting plate 234 is fixedly installed at the outlet of each set of pulse valves 232. A square blow pipe 233 is fixedly installed at the lower end of the flange connecting plate 234. A connecting frame 235 is fixedly connected to both ends of the square blow pipe 233. The connecting frame 235 is fixedly installed on the plate 211, and several sets of jet connecting pipes 236 corresponding to the installation port 212 are fixedly installed at the lower end of the square blow pipe 233. The lower end of the jet connecting pipe 236 is rotatably connected to the upper end of the jet pipe 224.

[0022] Furthermore: the air tank 231 stores compressed air; the pulse valve 232 controls the airflow release; the flange connecting plate 234, together with the square blow pipe 233, effectively distributes and guides the air; ensuring that the airflow is evenly distributed to each purification component 22, and during the pulse exhaust process, effectively driving the jet pipe 224 to rotate freely, optimizing the dust removal coverage, and improving the efficiency and reliability of automatic dust removal.

[0023] Reference Figure 7 and Figure 8 As shown, specifically in this embodiment, the feeding assembly 6 includes a fixed frame 601 fixedly installed at the lower end of the guide frame 4. A motor 602 is rotatably installed at the front end of the fixed frame 601. A rotating shaft 603 is rotatably installed inside the fixed frame 601. Several sets of feeding blades 604 are fixedly installed on the rotating shaft 603. The output shaft of the motor 602 is fixedly connected to one end of the rotating shaft 603.

[0024] Furthermore: the fixed frame 601 is used to stabilize the feeding structure; and the motor 602 provides power; the rotating shaft 603 drives the feeding blades 604 to rotate; thereby causing several sets of feeding blades 604 to continuously push and discharge dust, effectively preventing dust blockage, ensuring long-term stable operation of the equipment, and reducing the need for manual maintenance.

[0025] Reference Figure 1 and Figure 2 As shown, specifically, in this embodiment, an air inlet channel 5 is fixedly installed on the lower front side of the purification box 1, and an air outlet channel 7 is fixedly installed on the upper rear side of the purification box 1.

[0026] The working principle of this utility model is as follows: polluted air containing sawdust and dust enters the equipment through the air intake channel 5 on the lower front side of the purification box 1 under the negative pressure generated by the external fan, and the airflow enters the filtration area composed of multiple purification components 22. The polluted air then passes from the outside to the inside through the cloth bag 226 that is sleeved on the outside of the frame 223. The microporous structure of the cloth bag 226 allows air to pass through, while blocking and trapping most of the solid dust particles on the outer surface of the cloth bag 226, effectively achieving high-efficiency air purification.

[0027] As filtration progresses, the dust layer adhering to the outer surface of the filter bag 226 gradually thickens, leading to a decrease in purification efficiency. Subsequently, the pulse cleaning assembly 23 is activated to begin cleaning: compressed air stored in the air tank 231 is used to form a strong pulse airflow when the pulse valve 232 opens instantaneously. This airflow is distributed through the flange connecting plate 234 and the square blow pipe 233, and then enters the blow pipe 224 downward through the blow pipe 236. It is then ejected at high speed from the uniformly arranged, inclined blow holes 225 on the blow pipe 224. Due to the inclined design of the blow holes 225, the reaction force generated by the jet airflow drives the blow pipe 224 to rotate, allowing the pulse airflow to impact the inner wall of the filter bag 226 from all directions without dead angles, thereby effectively breaking and peeling off the dust cake adhering to the outer surface of the filter bag.

[0028] The dust removed during the pulse cleaning process falls downwards under its own gravity, is collected by the guide frame 4 and guided into the lower feeding assembly 6. When ash discharge is required, the motor 602 starts, driving the rotating shaft 603 and the feeding blades 604 fixed on it to rotate together, continuously and stably pushing the collected dust outwards to achieve material discharge.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
