[0023] In order to prevent the asphalt from solidifying during storage, the asphalt storage bin 1 is heated. During the heating process, the asphalt will produce some irritating and harmful gases. In order to avoid direct emission and cause air pollution and improve the environmental protection of the asphalt storage bin 1, a gas treatment box 2 is required to perform harmless treatment on the gas produced by the asphalt.

[0024] When in use, the fan 10 on the side wall of the gas treatment box 2 will start to draw the gas in the asphalt storage bin 1 into the gas treatment box 2, and then filter the gas through the internal filter plate 6 before discharging;

[0029] Several splicing pipes 42 provided herein are connected end to end by bolts, and the number of the splicing pipes 42 is determined according to the height of the asphalt storage bin 1. One side of the end of the splicing pipe 42 is connected to the connecting pipe 41 so that it is connected to the inner cavity of the asphalt storage bin 1, and then the tail end of the splicing pipe 42 is inserted into the gas processing box 2 so that the gas in the asphalt storage bin 1 can be extracted through the fan 10.

[0030] An adjustment mechanism 11 is installed on the upper wall of the gas processing box 2. The adjustment mechanism 11 can adjust the angle of the guide plate 9. The adjustment mechanism 11 includes a cross bar 111, an insertion rod 112, a main protrusion 113, a secondary protrusion 114 and a slot 115. The upper wall of the gas processing box 2 is provided with a slot 115. The lower wall of the cross bar 111 is provided with an insertion rod 112. The insertion rod 112 can be inserted into the gas processing box 2 through the slot 115. The side wall of one end of the insertion rod 112 located in the gas processing box 2 is provided with a main protrusion 113 and a secondary protrusion 114. The main protrusion 113 and the secondary protrusion 114 are respectively located on the upper and lower sides of the guide plate 9;

[0031] By moving the cross bar 111 upward or downward, the main protrusion 113 and the auxiliary protrusion 114 on the plug rod 112 can drive the guide plate 9 to adjust so that it changes its angle and guides the flow direction of the gas.

[0032] An electric control push rod 12 is installed on the side wall of the gas processing box 2. The electric control push rod 12 is electrically connected to an external power supply, and the output end of the electric control push rod 12 is connected to the cross bar 111;

[0034] A sealing ring 13 is installed in the slot 115, and the sealing ring 13 is sleeved on the outer side of the insertion rod 112;

[0035] The sealing ring 13 can improve the sealing performance of the connection between the insertion rod 112 and the slot 115 , thereby preventing the gas in the gas processing box 2 from escaping through the slot 115 .

[0036] The upper wall of the bin cover 3 is provided with a feed port 14, into which a closing cover 15 is inserted and installed, and the lower wall of the asphalt storage bin 1 is provided with a discharge port 16;
