[0042] An electric screw rod elevator 35 is arranged at the top of the dust extraction main 24. The upper part of the valve rod 26 is a screw rod. The valve rod 26 is lifted or lowered by the electric screw rod elevator 35.

[0043] A flange plate is arranged at the bottom of the dust extraction cylinder 22.

[0044] An outwardly expanding second guide plate 44 is arranged at the open end of the guide groove 42. The two side plates of the guide groove 42 are inwardly converging, forming a resilient clamping plate 45. The guide groove 42 is made of spring steel or stainless steel.

[0045] Universal wheels 46 are arranged at the four corners of the bottom of the recovery box 43.

[0046] A handle 47 is arranged at one end of the recovery box 43.

[0047] The dust remover body 41 comprises a dust removal shell 48, a set of dust removal cloth bags 49 and a gas storage bag 50. The dust removal shell 48 is provided with a partition installation plate 51, by which the inner cavity of the dust removal shell 48 is divided into a clean air area 52 and a dust removal area 53. The set of dust removal cloth bags 49 are respectively installed at the bottom of the partition installation plate 51 and located in the dust removal area 53. The gas storage bag 50 is installed at the top of the partition installation plate 51 and located in the clean air area 52. A set of blowing pipes are arranged on the outer wall of the gas storage bag 50, and an electromagnetic valve is arranged on the blowing pipe. The outlet end of the blowing pipe is provided with a spray head located in the dust removal cloth bag 49. An induced draft fan 54 is arranged at the top of the dust removal shell 48, and the air inlet of the induced draft fan 54 is communicated with the clean air area 52. A suction box 55 is arranged on one side of the dust removal shell 48. The suction box 55 is an isosceles trapezoidal box. An air outlet is opened at the bottom of the suction box 55, and the air outlet is communicated with the dust removal area 53. A dust removal air inlet 56 is arranged at the top of the dust removal shell 48, and the dust removal air inlet 56 is communicated with the outlet end of the dust removal main pipe 24.

[0048] A guide groove is opened at one side of the bottom of the discharge port of the dust remover body 41. An L-shaped discharge plate 57 is arranged in the guide groove. The L-shaped discharge plate 57 is inserted into or extracted from the guide groove to control the opening or closing of the discharge port of the dust remover body 41.

[0049] In embodiment 1, the bottom flange plate of the dust extraction cylinder 22 is bolted on the first dust extraction port at the top of the sand blasting shell 1. The side air suction pipe 29 of the cyclone dust remover 21 is connected with the second dust extraction port at the upper part of the collection hopper of the sand blasting shell 1. The dust extraction main pipe 24 is communicated with the pulse bag dust remover. The dust-containing gas sucked by the side air suction pipe 29 enters the cyclone dust remover 21. The gas is input into the dust extraction main pipe 24 through the inner cylinder 28. The large particle impurities fall into the slag discharge hopper 31 through the outer cylinder 27. The dust-containing gas extracted by the branch dust extraction pipe 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. The dust-containing gas extracted by the side air suction pipe 29 and the branch dust extraction pipe 32 is uniformly transported to the pulse bag dust remover through the dust extraction main pipe 24.

[0050] The electric screw rod elevator 35 drives the adjusting valve flap 23 to rise or fall through the valve rod 26. When the adjusting valve flap 23 rises, the size of the dust extraction port of the inner cylinder 28 can be adjusted. When the adjusting valve flap 23 rises to the uppermost position, the adjusting valve flap 23 closes the inner cylinder 28 to stop dust removal.

[0051] When the adjusting valve flap 23 falls, it gradually fits the inner wall of the outer cylinder 27 to close the slag discharge port at the bottom of the outer cylinder 27. The first dust extraction port stops dust extraction, and only the second dust extraction port performs dust extraction. The large particle impurities generated by the cyclone dust remover 21 fall on the top surface of the adjusting valve flap 23, and fall under the action of gravity when the adjusting valve flap 23 rises.

[0052] After a period of use, the plug 33 is pulled out, and the large-particle impurities in the slag discharge hopper 31 are discharged.

[0053] 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 hopper 30. The use of multiple branch dust extraction pipes 32 makes the dust extraction more uniform.

[0054] The induced draft fan 54 is started, and the dust extraction box 55 sucks in the dust-containing gas in the sandblasting machine through the dust extraction pipeline. The dust-containing gas enters the dust removal area 53, passes through a group of dust removal bags 49 for filtration, and then the clean air enters the clean air area 52 and is output by the induced draft fan 54. When it is necessary to clean the dust removal bags 49, the electromagnetic valve is opened, and the compressed air in the air storage bag 50 is output and sprayed into the dust removal bags 49 through the spray head to clean the dust.

[0055] The particulate impurities separated by the dust removal bags 49 fall to the bottom of the dust removal shell 48 and are discharged through the discharge port into the recovery box 43. When the recovery box 43 is full, the L-shaped discharge plate 57 is inserted into the guide groove to close the discharge port. The worker holds the handle 47 and pulls out the recovery box 43 for dumping. After dumping is completed, the recovery box 43 is inserted into the guide groove 42 along the second guide plate 44. Since the two side plates of the guide groove 42 are inwardly folded to form the elastic clamping plate 45, the recovery box 43 can be clamped and positioned by the side wall through the elastic clamping plate 45. After the recovery box 43 is pushed into place, the L-shaped discharge plate 57 is pulled out, and the particulate impurities are collected again.

[0056] The short edge of the L-shaped discharge plate 57 is upwardly raised, which facilitates the worker to hold the short edge and pull out the L-shaped discharge plate 57.

[0057] Universal wheels 46 are arranged at the four corners of the bottom of the recovery box 43, which makes the pulling out or pushing in of the recovery box 43 more smooth.
