An exhaust housing 114 is provided on the exhaust duct 113. The exhaust housing 114 is used to install an exhaust wheel 136. The exhaust pipe 117 is connected to the exhaust cylinder 116. The exhaust pipe 117 is installed on the mechanism housing 101. The end of the exhaust pipe 117 located outside the mechanism housing 101 is provided with a filter for filtering gas. The black end of the exhaust pipe 117 in the accompanying drawings is the filter. Since the filter mesh holes are relatively small, they are displayed in black in the accompanying drawings. A filter layer 146 is also provided at the connection between the ash discharge cylinder 115 and the exhaust cylinder 116. The filter layer 146 can be made of a filter or a material commonly used for filtering air in the prior art.

[0039] The inner guide plate 138 is concave in the middle, and the concave can precipitate some small dust impurities. One end of the inner guide plate 138 is fixedly mounted on the inner wall of the ash discharge cylinder 115 . The inner guide plate 138 is located below the connection between the exhaust duct 113 and the ash discharge cylinder 115 .

[0040] Working principle of the present invention: When in use, the present invention starts the outer cover motor 102 to drive the outer cover connecting rod 103 to rotate, thereby rotating the outer cover block 105 and the outer cover body 104. The outer cover body 104 will slide on the connecting plate 107 under the action of the outer cover slide 106, and at the same time drive the connecting plate 107 to rotate an angle to cooperate with the opening of the outer cover body 104.

[0041] After opening, connect the air outlet of the shot blasting machine to a pipe or a channel for collecting air, and connect it to the entrance of the air inlet channel 110. Then, while the shot blasting machine is working, start the main motor 118. After the main motor 118 is started, it will work in two circuits. The main motor 118 drives the main power shaft 120 to rotate, and drives the exhaust gear 135 to rotate under the action of the first pulley 119 and the first transmission belt 121, thereby rotating the exhaust wheel 136, and the air in the recovery cylinder 112 is pumped into the ash discharge cylinder 115 through the exhaust duct 113.

[0042] On the other hand, when the main power shaft 120 rotates, the exhaust gear 130 is driven to rotate under the action of the second front pulley 122, the curved belt 123, the second middle pulley 133, the guide pulley 132, and the second rear pulley 129, thereby rotating the exhaust wheel 137. The exhaust wheel 137 draws the air exhausted by the shot blasting machine into the air inlet channel 110 and discharges it from the outlet of the air inlet channel 110. Before discharge, the water spray ring 139 needs to be started for spraying. When the gas comes out from the outlet of the air inlet channel 110, due to the pumping action of the exhaust wheel 137, the gas will pass through the cone filter plate 141 into the inside of the recovery cylinder 112, and be wetted by the sprayed water. The water mist is used to liquefy the air so that impurities fall onto the cone filter plate 141, and pass through the cone filter plate 141 and fall into the sedimentation cylinder 109 below, and finally enter the storage box from the sedimentation cylinder 109 for storage. When impurities need to be processed, the cabinet door 108 is opened for operation.

[0043] When the above-mentioned spraying causes impurities and water to fall from the cone filter plate 141, the impurities in the gas discharged from the air inlet channel 110 can be knocked off first, and the dust gas can be preliminarily treated. Then the gas passes through the cone filter plate 141 and enters the recovery cylinder 112 for another liquefaction filtration treatment. When the water flow falls from the cone filter plate 141, it hits the conical seat 142. The conical seat 142 has a guiding function. The water flow can quickly gather on both sides of the conical seat 142, and flow out from both sides of the conical seat 142 and fall into the sedimentation cylinder 109.

[0044] The liquefied and filtered gas goes upward, and under the pumping action of the exhaust wheel 136, the gas is pumped from the exhaust duct 113 to the ash discharge cylinder 115. After reaching the ash discharge cylinder 115, the inner guide plate 138 can guide the air, and at the same time, some heavy small dust particles will accumulate on the inner guide plate 138. The remaining filtered gas will be filtered again through the filter layer 146, and the particulate impurities will fall to the bottom of the ash discharge cylinder 115 and enter the storage box. The clean gas is discharged from the exhaust pipe 117.

[0045] Any matters not described in the present invention are applicable to the prior art.
