[0023] As shown in the drawings, the utility model includes cyclone dust collector 21, dust extraction cylinder 22 and regulating valve 23,

[0024] The top of cyclone dust collector 21 is provided with dust extraction main pipe 24, dust extraction cylinder 22 is installed on the lower outer wall of cyclone dust collector 21, the cone cylinder of cyclone dust collector 21 is located in dust extraction cylinder 22, the bottom of dust extraction cylinder 22 is provided with top extraction pipe opening 25, regulating valve 23 is installed in cyclone dust collector 21, the top of regulating valve 23 is provided with valve rod 26, and regulating valve 23 is lifted or lowered by valve rod 26.

[0025] Cyclone dust collector 21 is composed of outer cylinder 27, inner cylinder 28 and side air extraction pipe 29, the lower part of outer cylinder 27 is a cone cylinder, inner cylinder 28 is installed at the top center of outer cylinder 27, dust extraction main pipe 24 is communicated with inner cylinder 28, and side air extraction pipe 29 is installed on the upper outer wall of outer cylinder 27.

[0026] Top extraction pipe opening 25 is composed of dust extraction funnel 30 and residue discharge funnel 31, a group of branch dust extraction pipes 32 are evenly arranged in annular shape on the lower outer wall of dust extraction funnel 30, and residue discharge funnel 31 is installed at the bottom of dust extraction funnel 30.

[0027] The bottom outlet end of residue discharge funnel 31 is provided with plug 33.

[0028] Regulating valve 23 is an inverted conical valve.

[0029] Valve rod 26 is provided with guide plate 34, both ends of guide plate 34 are arc-shaped and are in close contact with the inner wall of inner cylinder 28.

[0030] Dust extraction main pipe 24 is a bend pipe, and valve rod 26 penetrates dust extraction main pipe 24 upwards.

[0031] The top of dust extraction main pipe 24 is provided with electric screw rod elevator 35, the upper part of valve rod 26 is a screw rod, and valve rod 26 is lifted or lowered by electric screw rod elevator 35.

[0032] The bottom of dust extraction cylinder 22 is provided with flange plate.

[0033] The bottom flange of the dust extraction cylinder 22 is bolted to the first dust extraction port on the top of the sand blasting shell 1. The side air duct 29 of the cyclone dust collector 21 is connected to the second dust extraction port on the upper part of the collection funnel of the sand blasting shell 1. The dust extraction main pipe 24 is connected to the pulse bag dust collector. The dust-containing gas input by the side air duct 29 enters the cyclone dust collector 21. The gas is input to the dust extraction main pipe 24 through the inner cylinder 28. The large-particle impurities fall into the slag discharge funnel 31 through the outer cylinder 27. The dust-containing gas extracted by the branch dust extraction pipes 32 rises along the outer cylinder 27 to the inner cylinder 28, and then is output to the dust extraction main pipe 24 by the inner cylinder 28.

[0034] The electric screw rod elevator 35 drives the regulating valve flap 23 to rise or fall through the valve rod 26. When the regulating valve flap 23 rises, the size of the dust extraction port of the inner cylinder 28 can be adjusted. When the regulating valve flap 23 rises to the uppermost position, the regulating valve flap 23 closes the inner cylinder 28, and the dust removal is stopped.

[0035] When the regulating valve flap 23 falls, it gradually fits the inner wall of the outer cylinder 27, closes the slag discharge port at the bottom of the outer cylinder 27, and stops dust extraction at the first dust extraction port. Only the second dust extraction port is used for dust extraction. The large-particle impurities generated by the cyclone dust collector 21 fall on the top surface of the regulating valve flap 23, and fall under the action of gravity when the regulating valve flap 23 rises.

[0036] After a period of use, the plug 33 is pulled out, and the large-particle impurities in the slag discharge funnel 31 are discharged.

[0037] A group of branch dust extraction pipes 32 are arranged in a ring shape on the outer wall of the lower part of the dust extraction funnel 30. The use of multiple branch dust extraction pipes 32 makes the dust extraction more uniform.
