The gun body of the dust removal device is equipped with a distribution regulating valve, and an air jet pipe is located at the front end of the valve seat of the distribution regulating valve, communicating with a first valve port on the valve seat. A suction pipe is located outside the air jet pipe, and an ejector is located at the rear of the suction pipe; the high-pressure air pipe of the ejector communicates with a second valve port on the valve seat, and the dust removal pipe port of the ejector communicates with the suction pipe. A filter collection bag is connected to the exhaust pipe of the ejector. A control valve is located at the rear of the gun body, and the air pipe of the control valve communicates with a third valve port on the valve seat. The distribution regulating valve is manually adjusted in three positions. When the valve core of the distribution regulating valve is in the blowing dust removal position, compressed air enters the jet pipe for blowing dust removal; when the valve core of the distribution regulating valve is in the dust suction position, compressed air enters the jet injector for pneumatic dust suction; when the valve core of the distribution regulating valve is simultaneously in the blowing and dust suction positions, the jet pipe blows dust and the dust suction pipe performs dust suction.

[0005] Preferably, the front end of the jet pipe is provided with a nozzle, and the outside of the suction pipe is provided with a suction hood.

[0006] Preferably, a water spray dust removal device is provided at the lower end of the gun body, the water jet nozzle is connected in series with the air jet pipe, and a regulating valve is provided on the water inlet pipe of the water jet nozzle.

[0007] Based on the above technical solution, this utility model has at least one of the following beneficial effects: 1. This utility model provides a pneumatic blowing dust removal device. By rotating the valve core of the distribution regulating valve, it can perform three working modes as needed: blowing dust removal, pneumatic vacuum dust removal, and simultaneous blowing dust removal and pneumatic vacuum dust removal. The dust removal mode can be selected according to the dust removal conditions. The structure is simple and practical, and it greatly improves the pneumatic dust removal effect. The dust suppression effect is improved by using venturi jet water spray. Attached Figure Description

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0011] like Figure 1 As shown, a pneumatic dust removal device includes a gun body 2, a distribution regulating valve 3, an air jet pipe 5, a suction pipe 7, an ejector 8, and a filter collection bag 13. The gun body 2 of the dust removal device 1 is equipped with a distribution regulating valve 3, and an air jet pipe 5 is located at the front end of the valve seat 4 of the distribution regulating valve 3; the air jet pipe 5 communicates with the first valve port 6 on the valve seat 4. A suction pipe 7 is located outside the air jet pipe 5, and an ejector 8 is located at the rear of the suction pipe 7. The high-pressure air pipe 9 of the ejector 8 communicates with the second valve port 10 on the valve seat 4. The dust removal pipe port 11 of the ejector 8 communicates with the suction pipe 7, and a filter collection bag 13 is connected to the exhaust pipe 12 of the ejector 8. A control valve 14 is located at the rear of the gun body 2, and the exhaust pipe 15 of the control valve 14 communicates with the third valve port 16 of the valve seat 4. The distribution regulating valve 3 is manually adjustable in three positions. When the valve core 17 of the distribution regulating valve 3 is in the blowing dust removal position, compressed air enters the jet pipe 5 for blowing dust removal. When the valve core 17 of the distribution regulating valve 3 is in the suction dust removal position, compressed air enters the jet injector 8 for pneumatic suction dust removal. When the valve core 17 of the distribution regulating valve 3 is simultaneously in the blowing and suction dust removal positions, the jet pipe 5 performs blowing dust removal, and the suction pipe 7 performs suction dust removal. Adjusting the rotation angle of the valve core 17 controls the air pressure of the blowing and the vacuum suction force of the suction. A nozzle 18 is provided at the front end of the jet pipe 5, and the blowing jet angle is adjusted by the nozzle 18.
