[0002] In the metallurgical process, a steel rolling production line often includes a rough rolling unit, an intermediate rolling unit, a pre-finishing rolling unit and a finishing rolling unit. In the finishing rolling unit part, a diesel press is usually used for energy supply. When it works, a large amount of soot will be generated. Part of the soot is oil fume particles, and the other part is water vapor generated during cooling.

[0003] However, in the existing finishing rolling functions, dust-proof treatment is often not carried out. The dust-proof here is on the one hand to prevent the soot from being discharged outward, and on the other hand to prevent the discharged soot from being sucked back into the finishing rolling device.

[0009] Optionally, a first filter screen, an adsorption section, a second filter screen and a fan are arranged in the filter air guiding mechanism. The adsorption section is located between the first filter screen and the second filter screen. The first filter screen is close to the soot cavity, the fan is close to the dust-proof cavity, and the second filter screen is located between the adsorption section and the fan.

[0010] Optionally, the adsorption section is filled with activated carbon.

[0011] Optionally, a dust suction cover is arranged at one end of the filter air guiding mechanism located in the soot cavity.

[0012] Optionally, a gasket is arranged on the outer periphery of the filter air guiding mechanism.

[0013] The advantages of the utility model include:

[0014] 1. By providing a cover body and arranging a filtering air guiding mechanism therein, on the one hand, it can export the soot generated during the operation of the finishing mill for unified treatment and discharge it into the exhaust main pipe, protecting the environment of the working area. On the other hand, since it is connected to the exhaust main pipe, there will be no reverse suction of soot, thus realizing the protection function against soot.

[0015] 2. By providing the structure of the specific filtering air guiding mechanism, the first filter screen and the second filter screen can filter large particle impurities in the soot, while the adsorption section adsorbs water vapor and other soot that is not easily filtered based on the adsorption capacity of activated carbon, and the remaining soot is uniformly exported through the exhaust main pipe for treatment.

The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0023] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and proportion of each component in actual implementation can be arbitrarily changed, and the layout type of its components may also be more complex.

[0024] As Figures 1 to 3 shown, a dust-proof cover for a finishing mill device includes a cover body 5. The cover body 5 is arranged above the finishing mill 1. The air outlet end of the cover body 5 is connected with an exhaust branch pipe 3 and is communicated with an exhaust main pipe 2 through the exhaust branch pipe 3. A filter air guiding mechanism 4 is arranged in the cover body 5, and the filter air guiding mechanism 4 can introduce the soot from the inside of the finishing mill 1 into the cover body 5.

[0025] The purpose of such a design is that by arranging the cover body and setting the filter air guiding mechanism therein, on the one hand, it can export the soot generated during the operation of the finishing mill for unified treatment and discharge it into the exhaust main pipe, protecting the environment of the working area. On the other hand, since it is connected to the exhaust main pipe, there will be no back suction of soot, thus realizing the function of protecting against soot.

[0026] In this embodiment, a dust-proof cavity 6 is arranged in the cover body 5, a soot cavity 7 is arranged in the finishing mill 1, and the filter air guiding mechanism 4 communicates the dust-proof cavity 6 and the soot cavity 7.

[0027] The purpose of such a design is that in most scenarios, the soot generated inside the finishing mill will be concentrated in the soot cavity at its upper part. In this way, through the filter air guiding mechanism, it can be directly introduced into the dust-proof cavity and then flow into the exhaust main pipe through the exhaust branch pipe.

[0028] In this embodiment, as Figure 4 shown, the filter air guiding mechanism 4 is of a cylindrical structure. A first filter screen 11, an adsorption section 12, and a second filter screen 13 are arranged in the filter air guiding mechanism 4. The adsorption section 12 is located between the first filter screen 11 and the second filter screen 13. The first filter screen 11 is close to the soot cavity 7, and the second filter screen 13 is close to the dust-proof cavity 6.

[0029] The purpose of such a design is that by setting the structure of the unique filter air guiding mechanism, the first filter screen and the second filter screen can filter large particle impurities in the soot, while the adsorption section adsorbs water vapor and other soot that is not easily filtered based on the adsorption ability of activated carbon. The remaining soot is uniformly exported through the exhaust main pipe for treatment.

[0030] In this embodiment, as Figure 5As shown, the filtering air guiding mechanism 4 is of a cylindrical structure. A first filter screen 11, an adsorption section 12, a second filter screen 13 and a fan 14 are arranged in the filtering air guiding mechanism 4. The adsorption section 12 is located between the first filter screen 11 and the second filter screen 13. The first filter screen 11 is close to the soot chamber 7, the fan 14 is close to the dust-proof chamber 6, and the second filter screen 13 is located between the adsorption section 12 and the fan 14.

[0031] The purpose of such design is that by setting the structure of the unique filtering air guiding mechanism, the first filter screen and the second filter screen can filter large particle impurities in the soot, while the adsorption section adsorbs water vapor and other soot that is not easily filtered based on the adsorption capacity of activated carbon. The remaining soot is uniformly led out through the exhaust main pipe for treatment, and at the same time, the addition of the fan can improve the overall leading-out rate.

[0032] In this embodiment, the adsorption section 12 is filled with activated carbon.

[0033] It should be noted that in specific implementation, those skilled in the art can also choose other fillers with adsorption capacity when implementing.

[0034] In this embodiment, a dust suction hood 9 is arranged at one end of the filtering air guiding mechanism 4 located in the soot chamber 7, and a gasket 8 is arranged on the outer periphery of the filtering air guiding mechanism 4.

[0035] The purpose of such design is that by setting the dust suction hood, it is convenient for the soot to converge and be introduced, and by setting the gasket, it can achieve a good sealing effect. Usually, it is arranged in the dust-proof chamber and the soot chamber.
