[0023] The present invention will be further described below with reference to the accompanying drawings: Example

[0024] Reference Figure 1-4 An air filtration and circulation device for workshop dust removal includes a base 1, a guide pipe 7, and filter bags 9. A dust collection component is fixedly installed on the base 1 to ensure its stability. The dust outlet of the dust collection component is fixedly connected to one end of the guide pipe 7. Several filter bags 9 are evenly and detachably fixedly installed on both sides of the guide pipe 7. The filter bags 9 are connected to the guide pipe 7 so that the dust collection component can transport the air and dust from inside the workshop through the guide pipe 7 to the filter bags 9 for filtration, and allow the filtered air to directly pass through the filter bags 9 back into the workshop.

[0025] Specifically, the dust collection assembly includes a motor 2, a coupling 3, and a blower 4. The output end of the motor 2 is fixedly connected to the blower 4 through the coupling 3. The motor 2 and the blower 4 are fixedly mounted on the base 1. An air inlet hood 5 is fixedly mounted on the input end of the blower 4, and an air outlet hood 6 is fixedly mounted on the output end of the blower 4. The air outlet hood 6 is detachably connected to one end of the guide pipe 7 by bolts, so that the guide pipe 7 can be disassembled later for cleaning.

[0026] Motor 2 is controlled by a PLC controller.

[0027] Specifically, several straight-through valves 11 are evenly fixedly installed on both sides of the guide pipe 7. The straight-through valves 11 are connected to the inside of the guide pipe 7. The guide pipe 7 is detachably fixed to the filter bag 9 through the straight-through valves 11. By setting the straight-through valves 11, the filter bag 9 can be cut off from the guide pipe 7 individually. In this way, the filter bags 9 can be disassembled and replaced one by one without affecting the normal operation of the dust collection component.

[0028] The straight-through valve 11 can be a manual valve or a solenoid valve. If a solenoid valve is used, it is controlled by a PLC controller.

[0029] Specifically, an inspection cover 10 is detachably fixed to the end of the guide pipe 7 away from the air outlet shroud 6 by bolts, so that the internal condition of the guide pipe 7 can be checked later by removing the inspection cover 10.

[0030] Specifically, a connecting pipe 12 is fixedly installed on one side of the filter bag 9. One end of the connecting pipe 12 is inside the filter bag 9 and communicates with the inside of the filter bag 9. One end of the connecting pipe 12 is detachably fixedly connected to one end of the straight valve 11 by bolts.

[0031] Flanges are provided at the connection ends of the connecting pipe 12 and the straight valve 11.

[0032] Specifically, the surface of the connecting pipe 12 at one end inside the filter bag 9 has several holes 13 through it, so that the gas and dust inside the guide pipe 7 can enter the filter bag 9 more quickly through the holes 1.

[0033] Specifically, a bracket 8 is fixedly installed inside the filter bag 9. The bracket 8 is fixedly connected to the connecting pipe 12. The bracket 8 includes an upper support column 81, a lower support column 82, an upper cover plate 83, and a lower cover plate 84. One end of the upper support column 81 and the lower support column 82 are fixedly connected to the end of the connecting pipe 12 inside the filter bag 9, respectively. The other end of the upper support column 81 and the lower support column 82 is fixedly installed with the upper cover plate 83 and the lower cover plate 84, respectively. The filter bag 9 is fitted over the upper support column 81 and the lower support column 82. The upper cover plate 83 and the lower cover plate 84 are fixedly installed at the top and bottom of the filter bag 9, respectively. The bracket 8 can support the filter bag 9 and prevent the filter bag 9 from shaking excessively during the operation of the dust collection component.

[0034] In this embodiment, during use, the dust collection assembly and the guide pipe 7 are fixedly installed inside the workshop via the base 1, and the required number of filter bags 9 are installed on the guide pipe 7.

[0035] When the motor 2 drives the blower 4 through the coupling 3, it blows the air and dust in the air from the workshop into the guide pipe 7, and then into the filter bags 9 under the action of the straight valves 11. The filter bags 9 filter the dust in the air and retain the filtered dust in the filter bags 9. At the same time, the filtered air will directly pass through the filter bags 9 and return to the workshop, thereby avoiding unnecessary waste caused by the cold or hot air inside the workshop being discharged to the outside of the workshop.

[0036] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
