To collect this dust, dust hoods are typically installed outside the coke oven. However, existing hoods are relatively simple and ineffective. Furthermore, due to dimensional variations in oven columns and thermal deformation of the coke oven, the gap between the hood and the columns can become too large, compromising the sealing effect.

[0006] Preferably, the arc-shaped cover body and the door-shaped cover body are both hollow structures, and the hollow structures of the arc-shaped cover body and the door-shaped cover body are connected. An air distribution duct is installed at the end of the arc-shaped cover body, and the air distribution duct is connected to the hollow structure of the arc-shaped cover body. A medium-pressure fan is connected to the air distribution duct, and multiple air outlets are arranged on the contact surface between the door-shaped cover body and the coke oven door.

[0007] Compared with the prior art, the present invention has the following technical effects: the present invention has a simple structure and a reasonable design, adopts a special-shaped sealing cover structure, can better fit the furnace door, and the sealing cover is controlled to move by the transverse frame and the longitudinal movement mechanism, and the movement is more convenient; and the sealing cover adopts a hollow structure, can blow air into the hollow chamber of the dust collecting cover through the fan, and form a wind wall between the furnace column and the dust collecting cover, the sealing effect is obvious, and smoke leakage is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0011] like Figure 1 and Figure 2 As shown, a sealing structure of a heat recovery vehicle and a coke oven door is provided, comprising a main frame 1 and a dust collecting hood 2. A first track 3 is installed on one side of the main frame 1, and a second track 4 is installed on the other side through two columns. The first track 3 and the second track 4 are arranged at different heights. A transverse frame 5 is installed on the first track 3 and the second track 4. Two longitudinal guide rails 6 are installed on the transverse frame 5. The dust collecting hood 2 is installed on the two longitudinal guide rails 6 through a plurality of supporting wheels 9; the dust collecting hood 2 comprises an arcuate hood body 7 and a door-type hood body 8 installed at the end of the arcuate hood body. A plurality of supporting wheels 9 are installed on both sides of the arcuate hood body 7. The door-type hood body 8 is used to cooperate with the coke oven door for sealing.

[0012] In the present invention, the dust hood 2 is installed on the transverse frame 5. The dust hood 2 can move longitudinally on the transverse frame 5, and the transverse frame 5 can move laterally on the main frame 1, making the movement of the dust hood 2 more convenient. The dust hood 2 adopts a special-shaped structure, including an arc-shaped cover body 7 and a door-shaped cover body 8, which can better use the heat recovery vehicle and the coke oven door to ensure the sealing effect. A driving mechanism for driving the transverse frame to move is also installed on the second track 4. The driving mechanism includes a driving sprocket and a driven sprocket installed at both ends of the second track 4. A driving chain 10 is installed between the driving sprocket and the driven sprocket. A reduction motor 11 is installed on the driving sprocket, and the transverse frame is installed on the driving chain through a connecting plate 12. The movement of the transverse frame 5 can be controlled by the driving chain 10, and the movement is more flexible and convenient.

[0013] The curved hood 7 and the door-shaped hood 8 are both hollow structures, and the hollow structures of the curved hood 7 and the door-shaped hood 8 are connected. An air distribution duct 13 is installed at the end of the curved hood 7, which is connected to the hollow structure of the curved hood 7. A medium-pressure fan 14 is connected to the air distribution duct 13. Multiple air outlets 15 are provided on the contact surface between the door-shaped hood 8 and the coke oven door. The curved hood 7 and the door-shaped hood 8 are hollow structures, and air can be distributed by the medium-pressure fan 14. The high-pressure air passes through the air outlets 15 to form an air wall between the furnace column and the dust collection hood, thereby ensuring a good seal and greatly reducing smoke leakage.

[0014] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
