Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a mobile industrial dust collection device. Background Technology

[0002] A large amount of dust is generated during industrial production. If this dust is not dealt with in time, it will not only pollute the environment, but also harm the health of workers. Therefore, it is necessary to install dust collection devices to collect and clean up the dust in the industrial production environment.

[0003] Existing dust collection equipment mainly uses filter bags to filter dust. During the filtration process, dust accumulates on the surface of the filter bags, requiring regular cleaning to ensure effective dust removal. Conventional methods for cleaning filter bags primarily involve using pulse valve assemblies to blow air into the filter bags, shaking off the dust from the outer walls.

[0004] Although the above-mentioned dust removal methods can achieve dust removal of the filter bags to a certain extent, the bottom of the filter bags is far from the pulse back-flushing air inlet, and the back-flushing air pressure at this location is relatively low, resulting in poor dust removal effect. Moreover, after the dust falls into the ash hopper, it may also adhere to the inner wall of the ash hopper. When the dust-laden gas enters the dust collector, it may blow up the dust on the inner wall of the ash hopper, causing the dust to adhere to the outer wall of the filter bags again, thereby reducing the working efficiency of the dust removal equipment. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a mobile industrial dust collection device that combines pulse backflushing and vibration cleaning to effectively improve the dust removal effect, ensure the long-term efficient operation of the dust removal equipment, and prevent the dust collected in the dust removal equipment from generating secondary dust, resulting in high dust removal efficiency.

[0006] To achieve the above objectives, this utility model provides a mobile industrial dust collection device, including a dust collection box and a fan, a filter assembly, and a pulse cleaning assembly disposed within the dust collection box. The fan is located on top of the filter assembly, and the pulse cleaning assembly is located between the filter assembly and the fan. The filter assembly includes several filter cartridges, each with an open top and a closed bottom. The dust collection box has an air inlet on its side wall and an exhaust outlet on its top.

[0007] The bottom of the filter assembly is equipped with a mechanical dust removal assembly, which includes a connecting frame, a transmission rod, a fork, a rotating shaft, and a flap. The bottom end of each filter cartridge is fixedly connected to the connecting frame, and the end of the connecting frame near the air inlet is fixedly connected to the transmission rod. The rotating shaft passes through one end of the fork and is rotatably connected to the fork. The rotating shaft is fixed relative to the dust collection box. A torsion spring is sleeved on the rotating shaft, with one end fixedly connected to the rotating shaft and the other end fixedly connected to the fork. The fork can abut against the transmission rod under the action of the torsion spring. The flap is fixed to one side of the insertion rod and is located at the air inlet. Under the air pressure at the air inlet, the flap can drive the fork to deflect away from the air inlet.

[0008] Furthermore, the fork is a V-shaped rod formed by connecting the ends of the first and second support rods. The transmission rod passes between the first and second support rods. The first support rod is located on the side of the second support rod away from the air inlet. The first support rod abuts against the transmission rod under the action of the torsion spring. The flap is fixed to the side of the second support rod near the air inlet.

[0009] Furthermore, the connecting frame includes a main rod, several connecting rods, and a threaded sleeve. One end of the main rod is fixedly connected to the transmission rod, one end of the connecting rod is fixedly connected to the main rod, and the other end is movably connected to the threaded sleeve. The bottom end of each filter cartridge is fixed with a screw, and the connecting rod is threadedly connected to the screw through the threaded sleeve.

[0010] Furthermore, the pulse cleaning assembly includes a cleaning pressure tank and several pulse branch pipes. The cleaning pressure tank is fixed inside the dust collection box. The pulse branch pipes are connected to the cleaning pressure tank. Several air nozzles are connected to the pulse branch pipes. Each air nozzle corresponds to a filter cartridge and is located at the top of the filter cartridge opening.

[0011] Furthermore, the bottom of the mechanical dust removal assembly is provided with a dust collection box, and the side wall of the dust collection box is provided with a dust collection box loading and unloading door. Several pulleys are rotatably connected to the two inner side walls adjacent to the dust collection box loading and unloading door, and the dust collection box is placed on the pulleys.

[0012] Furthermore, a water tank is provided on the outer wall of the dust collection box, and the water tank is connected to a water inlet pipe through a pump body. One end of the water inlet pipe is inside the dust collection box and located at the top of the dust collection box. An atomizing nozzle is connected to the water inlet pipe.

[0013] Furthermore, several rollers are installed at the bottom of the dust collection box.

[0014] The beneficial effects of this utility model are:

[0015] The dust collection device of this utility model is equipped with a dual dust removal structure design of pulse cleaning component and mechanical cleaning component. During start-up, shutdown and operation, the dust collection device uses the air pressure at the air inlet to knock and vibrate the dust on the surface of the filter cartridge to remove dust. Since the mechanical cleaning component is connected to the bottom of the filter cartridge, it has a better dust removal effect on the bottom surface of the filter cartridge. Combined with the pulse cleaning component, it improves the problem of insufficient back-blowing air pressure at the bottom of the filter cartridge 31 in the pulse cleaning component and poor dust removal effect, effectively improving the dust removal effect.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] This utility model discloses a mobile industrial dust collection device.

[0024] Reference Figure 1 and Figure 2A mobile industrial dust collection device includes a dust collection box 1 and a fan 2, a filter assembly 3, and a pulse cleaning assembly 5 installed inside the dust collection box 1. The fan 2 is located on top of the filter assembly 3, and the pulse cleaning assembly 5 is located between the filter assembly 3 and the fan 2. The filter assembly 3 includes several filter cartridges 31, each open at the top and closed at the bottom. The dust collection box 1 has an air inlet 11 on its side wall and an exhaust outlet 12 at its top. Several rollers 14 are installed at the bottom of the dust collection box 1 to facilitate movement of the device and improve dust collection efficiency. When the fan 2 operates, it draws dusty air from the outside into the dust collection box 1 through the air inlet 11. The filter cartridges 31 filter the dust in the incoming air, and the filtered clean air is discharged through the top exhaust outlet 12, thus achieving the dust collection and purification function.

[0025] Reference Figure 1 and Figure 2 The pulse cleaning assembly 5 includes a cleaning pressure tank 51 and several pulse branch pipes 52. The cleaning pressure tank 51 is fixed inside the dust collection box 1 and is connected to an external air compressor via a pipe. The pulse branch pipes 52 are connected to the cleaning pressure tank 51 and are equipped with several air nozzles 53. Each air nozzle 53 corresponds to a filter cartridge 31 and is located at the top of the opening of the filter cartridge 31. When too much dust is adsorbed on the surface of the filter cartridge 31, the pulse cleaning assembly 5 can be activated to back-blow the filter cartridge 31 through the air nozzles 53, thereby blowing off the dust adsorbed on the surface of the filter cartridge 31 and achieving cleaning.

[0026] Reference Figure 2 and Figure 3 The bottom of the filter assembly 3 is provided with a mechanical cleaning assembly 6. The mechanical cleaning assembly 6 includes a connecting frame 61, a transmission rod 62, a fork rod 63, a rotating shaft 64, and a flap 65. The bottom end of each filter cartridge 31 is fixedly connected to the connecting frame 61. The connecting frame 61 includes a main rod 611, several connecting rods 612, and a threaded sleeve 613. The main rod 611 extends in a direction perpendicular to the air inlet 11. The end of the main rod 611 near the air inlet 11 is fixedly connected to the transmission rod 62. One end of each connecting rod 612 is welded and fixed to the main rod 611, and the other end is movably connected to the threaded sleeve 613. The bottom end of each filter cartridge 31 is fixed with a screw, and the connecting rod 612 is threadedly connected to the screw through the threaded sleeve 613.

[0027] A rotating shaft 64 passes through one end of a fork 63 and is rotatably connected to it. The rotating shaft 64 is fixed to the inner wall of the dust collection box 1. A torsion spring 66 is fitted on the rotating shaft 64. One end of the torsion spring 66 is inserted into the rotating shaft 64 and fixed thereto, while the other end is fixedly connected to the fork 63. The fork 63 is a V-shaped rod formed by connecting the ends of a first support rod 631 and a second support rod 632. A transmission rod 62 passes between the first support rod 631 and the second support rod 632. The first support rod 631 is located on the side of the second support rod 632 away from the air inlet 11. The side wall of the first support rod 631 abuts against the transmission rod 62 under the action of the torsion spring 66. A flap 65 is fixed to the side of the second support rod 632 near the air inlet 11. Under the air pressure of the air inlet 11, the flap 65 can drive the fork 63 to deflect away from the air inlet 11.

[0028] When the dust collection device is running, the flap 65, under the air pressure of the air inlet 11, drives the fork 63 to deflect away from the air inlet 11. Then, the second support rod 632 rotates and strikes the transmission rod 62. Due to the air pressure fluctuation at the air inlet 11 and the torsional action of the torsion spring 66, the fork 63 repeatedly deflects and strikes the transmission rod 62. The transmission rod 62 transmits the striking vibration to the filter cartridge 31 through the connecting frame 61, thereby shaking off the dust on the surface of the filter cartridge 31 and achieving mechanical dust removal from the surface of the filter cartridge 31. Since this mechanical dust removal is connected to the bottom of the filter cartridge 31, the vibration effect decreases from bottom to top, resulting in better dust removal effect on the bottom surface of the filter cartridge 31.

[0029] Reference Figure 2 The bottom of the mechanical dust removal assembly 6 is provided with a dust collection box 4. The side wall of the dust collection box 1 is provided with a dust collection box loading and unloading door. Several pulleys 41 are rotatably connected to the two inner side walls of the dust collection box 1 and the dust collection box loading and unloading door. The dust collection box 4 is placed on the pulleys 41 for easy loading and unloading of the dust collection box 4.

[0030] Reference Figure 4 To reduce the possibility of dust being emitted from the dust collection box 4 during operation of the dust collection device, a water tank 13 is installed on the outer wall of the dust collection box 1. The water tank 13 is connected to a water inlet pipe 131 via a pump body. One end of the water inlet pipe 131 extends into the dust collection box 1 and is located at the top of the dust collection box 4. An atomizing nozzle 132 is connected to the water inlet pipe 131. By spraying water mist, the occurrence of dust emission from the dust collection box 4 is effectively suppressed.

[0031] The working principle of this mobile industrial dust collection device is as follows: The dust collection device is equipped with a dual dust collection structure design of pulse cleaning component 5 and mechanical cleaning component 6. During operation, the flap 65, under the air pressure of the air inlet 11, drives the fork 63 to deflect away from the air inlet 11. Then, the second support rod 632 rotates and strikes the transmission rod 62. Due to the air pressure fluctuation at the air inlet 11 and the torsional action of the torsion spring 66, the fork 63 repeatedly deflects and strikes the transmission rod 62. The transmission rod 62 transmits the striking vibration to the filter cartridge 31 through the connecting frame 61, thereby shaking off the dust on the surface of the filter cartridge 31 and achieving mechanical dust removal. Since the mechanical cleaning component 6 is connected to the bottom of the filter cartridge 31, the vibration effect decreases from bottom to top, resulting in better dust removal effect on the bottom surface of the filter cartridge 31. This compensates for the deficiency of insufficient back-blowing air pressure and poor dust removal effect at the bottom of the filter cartridge 31 in the pulse cleaning component 5. Meanwhile, the pulse cleaning component 5 can be activated periodically to back-blow the filter cartridge 31 through the air nozzle 53, thereby blowing off the dust adsorbed on the surface of the filter cartridge 31. The combination of the two cleaning mechanisms effectively improves the cleaning effect on the filter cartridge 31.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
