At present, the existing dust collection and sealing devices mainly adopt the method of spring pressing the baffle for sealing, which is easy to cause wear on the furnace frame. Content of the Utility Model

[0003] In order to solve the technical problems existing in the prior art, the utility model provides a coke oven flue gas dust collection and sealing device with simple structure, reasonable design, good dust collection effect and no wear on the furnace frame.

[0004] To achieve the above object, the technical solution adopted by the utility model is a coke oven flue gas dust collection and sealing device, including a dust collection hood, the dust collection hood is installed on the top rail of the coke oven through rollers, a cloth air duct is installed on one side of the dust collection hood, the two ends of the cloth air duct are connected with air inlet pipes, a blower is connected to the air inlet pipes, a cloth air distribution component is arranged on the cloth air duct, the cloth air distribution component is provided with a plurality of air outlets, the shape of the cloth air distribution component is the same as the shape of the coke oven flue gas outlet, and the cloth air distribution component is used for being inserted into the coke oven flue gas outlet.

[0005] Preferably, the cloth air distribution component includes an upper bent plate, a lower bent plate and a cloth air distribution plate, the upper bent plate and the lower bent plate are respectively fixed on one side of the cloth air duct, the cloth air distribution plate is installed between the gaps of the upper bent plate and the lower bent plate, and a plurality of the air outlets are arranged on the cloth air distribution plate.

[0006] Preferably, a buffer rubber pad is further installed on the outer side of the cloth air duct, and the buffer rubber pad is arranged above the cloth air distribution component.

[0007] Compared with the prior art, the utility model has the following technical effects: the utility model has a simple structure and is convenient to use. The cloth air duct is installed at the contact position between the dust collection hood and the coke oven flue gas outlet, and the cloth air distribution component is installed on the cloth air duct. The air is pressurized by the blower and blown out from the air outlets of the cloth air distribution component, so that a wind wall is formed in the gap between the dust collection hood and the coke oven flue gas outlet for sealing. This sealing will greatly improve the situation of poor sealing and wear on the furnace frame in the traditional sealing. Description of the Drawings

[0008] Figure 1 It is a schematic structural diagram of the utility model.

[0009] Figure 2 For Figure 1 the side view.

[0010] Figure 3 For Figure 1 the partial enlarged view at I in Detailed implementation mode

[0011] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be 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 utility model and are not used to limit the present utility model.

[0012] As Figures 1 to 3 shown, a dust collection and sealing device for coke oven flue gas includes a dust collection hood 1. The dust collection hood 1 is installed on the top slide rail of the coke oven through rollers 2. A cloth air duct 3 is installed on one side of the dust collection hood 1. Both ends of the cloth air duct 3 are connected with an air inlet pipe 4. A blower 5 is connected to the air inlet pipe 4. A cloth air distribution component 6 is arranged on the cloth air duct 4. The cloth air distribution component 6 is provided with a plurality of air outlets 7. The shape of the cloth air distribution component 6 is the same as the shape of the smoke outlet of the coke oven, and the cloth air distribution component 6 is used for being inserted into the smoke outlet of the coke oven.

[0013] The present utility model arranges a cloth air duct 3 between the dust collection hood 1 and the smoke outlet of the coke oven. The cloth air duct 3 is installed with a cloth air distribution component 6, and the cloth air distribution component 6 is provided with a plurality of air outlets 7. When the dust collection hood 1 slides to the dust collection position, the cloth air distribution component 6 is inserted into the smoke outlet of the coke oven, and a wind wall is formed through the plurality of air outlets 7 in the gap between the dust collection hood and the smoke outlet of the coke oven for sealing. In this way, the situation of smoke leakage can be effectively avoided, and the coke oven door frame will not be worn.

[0014] Among them, the cloth air distribution component 6 includes an upper bent plate 8, a lower bent plate 9 and a cloth air distribution plate 10. The upper bent plate 8 and the lower bent plate 9 are respectively fixed on one side of the cloth air duct 3. A cloth air distribution plate 10 is installed between the gaps of the upper bent plate 8 and the lower bent plate 9. The plurality of air outlets 7 are arranged on the cloth air distribution plate 10. Adopting this design can better cooperate with the coke oven and form a sealed wind wall at the gap, improving the sealing reliability. A buffer rubber pad 11 is also installed on the outer side of the cloth air duct 10. The buffer rubber pad 11 is arranged above the cloth air distribution component 6 to avoid damaging the cloth air duct when the dust collection hood moves.

[0015] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present utility model shall be included within the scope of the present utility model.
