Description

Technical Field

[0001] This utility model relates to the technical field of dust recycling devices, and in particular to a dust recycling device for workshops. Background Technology

[0002] The dust recovery and utilization device consists of several main parts, including a dust collection module, a conveying system, a purification and separation device, and other auxiliary equipment. It mainly includes a dust collection hood, a negative pressure fan, a screw conveyor, and filter bag assemblies. The purification and separation device is responsible for filtering and classifying the transported mixed dust, ensuring that the purity and particle size parameters of the recovered dust meet reuse requirements. A pulse solenoid valve is used to clean the dust adhering to the filter bag surface.

[0003] Existing dust recovery and utilization devices have a limited number of suction points, making precise dust collection difficult. They also have a narrow suction area, slow airflow, and dust tends to accumulate in the pipes. The suction fans have high power, resulting in low energy efficiency. The suction port has a limited fixing method, leading to low air cleanliness inside the workshop. Filter screens are prone to clogging, resulting in low dust recovery efficiency. Furthermore, the high air pressure at the suction fan outlet makes it difficult to collect dust, causing dust to settle and resulting in poor system stability.

[0004] Therefore, there is an urgent need to design a solution to the above problems. Utility Model Content

A dust collection fan device 2 is fixedly connected to the outer wall of one end of the main dust collection pipe 6. An exhaust pipe 7 is provided at the outlet of the dust collection fan device 2. A cyclone dust collector 3 is welded to the outer wall of one end of the exhaust pipe 7. A ventilation pipe 8 is sleeved on the top of the cyclone dust collector 3. A filter dust collector 4 is welded to the outer wall of one end of the ventilation pipe 8. An exhaust pipe 9 is welded to one side of the outer wall of the filter dust collector 4. A rain cover 10 is welded to one side of the top of the exhaust pipe 9. A dust collection branch pipe 11 is provided inside the dust collection device 1. A rain cover 10 is provided on one side of the outer wall of the dust collection branch pipe 11. It includes a pneumatic butterfly valve 12, a suction hose 13 sleeved on one side of the bottom of the suction branch pipe 11, a suction movable pipe 14 sleeved on one end of the bottom of the suction hose 13, a suction port 15 welded to one end of the suction movable pipe 14, a fixing plate 16 welded to one side of the suction movable pipe 14, and a bolt hole 17 on one side of the fixing plate 16. This increases the number of suction points, achieves precise suction, increases the suction area, increases the suction air velocity, and prevents the suction device from doing useless work. The suction fan device 2 has a fan impeller device 18 inside, and a drive motor 19 sleeved on one side of the fan impeller device 18. A base 20 is welded to the bottom of the machine 19, and vibration damping legs 21 are welded to the bottom of the base 20. This reduces the power of the dust collection fan, improves the energy efficiency of the device, and increases the fixing method of the dust collection port, thereby improving the cleanliness of the air inside the workshop. The cyclone dust collector 3 has a separator cylinder 22 inside, and a separator inner cylinder 23 is sleeved inside the separator cylinder 22. A separator cone 24 is welded to the bottom of the separator cylinder 22, and a powder collection bucket 29 is snapped into the bottom of the separator cone 24, reducing the clogging of the filter screen by large particles. The dust collector 4 has a dust collector housing 25 inside, and one side of the dust collector housing 25 is externally... The wall has a dust collector air inlet 26. A dust collector support leg 27 is welded to the bottom outer wall of the dust collector housing 25. A dust collector cone 28 is welded to the bottom outer wall of the dust collector housing 25. A baffle 30 is welded inside the dust collector housing 25. A filter barrel 31 is inserted into the top outer wall of the baffle. A compressed air tank 32 is installed on the top outer wall of the dust collector housing 25. A compressed air inlet 33 is inserted into the outer wall of the compressed air tank 32. A backflush pipe 34 is inserted into the outer wall of the compressed air tank 32. A backflush valve 35 is sleeved on the outer wall of the backflush pipe 34. A glass sight glass 5 is installed on the outer wall of the dust collector housing 25.

[0025] Furthermore, the vacuuming device 1 is located on the outer wall of the bottom side of the vacuuming main pipe 6, and the diameter of the vacuuming main pipe 6 is larger than the diameter of the vacuuming branch pipe 11, which increases the airflow speed, prevents the vacuuming device from doing useless work, and reduces the power of the vacuuming fan.

[0026] Furthermore, the diameter of the suction pipe 6 is larger than the diameter of the outlet pipe 7, and the outlet pipe 7 is tangent to the fan impeller device 18, which promotes the settling of large dust particles, reduces the air pressure at the outlet of the fan impeller device 18, and improves the dust recovery efficiency.

[0027] Furthermore, the air outlet duct 7 is tangent to the outer wall of the separator cylinder 22, and the separator inner cylinder 23 is located at the center of the separator cylinder 22, which improves the dust collection effect and uses centrifugal force to collect larger dust particles.

[0028] Furthermore, the baffle 30 is located above the dust collector inlet 26, and the baffle 30 separates the dust collector inlet 26 from the connection port of the exhaust pipe 9, which facilitates the collection of dust, reduces the wind speed at the dust outlet, and improves the dust settling effect.

[0029] Furthermore, one end of the backflush pipe 34 is located inside the filter barrel 31, and the diameter of the filter barrel 31 is larger than that of the backflush pipe 34, which improves the service life of the filter barrel 31 and ensures the stable operation of the system.

[0030] Working Principle: In use, install the dust collection device 1 in a suitable location, then place the remaining equipment in a rainproof outdoor environment. Next, selectively open the pneumatic butterfly valve 12 at different workstations, and then start the drive motor 19. The drive motor 19 rotates, driving the fan impeller device 18 to rotate. At this time, the system begins to absorb dust-containing air from the suction port 15, then enters the main suction pipe 6 through the suction branch pipe 11, increasing the number of dust collection points and achieving precise dust collection. The air then enters the fan impeller device 18, where the pressurized air is forced into the cyclone dust collector 3. The rotating mechanism causes large dust particles to fall into the powder collection bin 29. The air that has passed through the first filtration exits from the inner cylinder 23 of the separator, improving dust recovery efficiency, reducing the air pressure at the outlet of the dust collector, and reducing the power of the dust collector. The air then enters the dust removal device 4, passes through the dust collector housing 25, and is discharged to the outside through the exhaust pipe 9. When the filter bin 31 becomes clogged, the backflush valve 35 is opened, and compressed air is blown into the filter bin 31 from inside the compressed air storage tank 32 through the backflush pipe 34. The dust on the surface of the filter bin 31 is then blown off and enters the bottom of the dust collector cone 28. The dust is then collected by replacing the powder collection bin 29, thus achieving dust recycling.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
