[0008] The shell is erected above the dust source point;

[0009] An air extraction channel, which passes through the shell from top to bottom;

[0010] A plurality of partitions are provided vertically in the air extraction channel;

[0011] The air extraction port is arranged at the bottom of the shell and located between adjacent partitions.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0027] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0029] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0030] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0031] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0032] like Figure 1-3A plate dust removal system with a built-in dust collecting device is shown, including a shell 1, which is a long strip structure and is horizontally erected above the dust source point, that is, across the conveyor belt of the rolling mill. The shell 1 is provided with an exhaust channel 2 that runs through from top to bottom, and an exhaust port 4 is provided at the bottom of the exhaust channel 2, and the top is connected to the external wind hood. Several groups of partitions 3 are arranged in the exhaust channel 2, and the partitions 3 are arranged vertically and perpendicular to the long side of the shell 1, that is, parallel to the running direction of the conveyor belt. The partitions 3 are first used to divide the large exhaust channel 2 into multiple small exhaust channels 2. The exhaust effect of the small channels is more uniform than that of the large channels. Secondly, the partitions 3 can play the role of reinforcing ribs at the exhaust channel 2 in the shell 1. Since the steel plate will bend during the steel rolling process, the bent and warped steel plate will occasionally touch the dust collecting device above. The partitions 3 improve the structural strength of the dust collecting device and can well cope with the collision of the steel plate.

[0033] A through hole 7 is provided on the partition 3. Firstly, the partition 3 with a hole in the middle can reduce weight. Secondly, the through hole 7 can connect the adjacent small air extraction channel 2, and the air flow path will be smoother, which is conducive to dust collection. The air extraction port 4 is arranged at the bottom of the shell 1 and is located between adjacent partitions 3. In order to ensure the wind speed during air extraction, the ratio of the cross-sectional area of ​​the air extraction port 4 to the air extraction channel 2 needs to be accurately designed. Several air extraction ports 4 are arranged at the bottom of the shell 1.

[0034] Preferably, the air extraction channel 2 is provided with a plurality of baffles 5, which divide the air extraction channel 2 into a plurality of independent air extraction units. Since the housing 1 has a certain length, a single air hood docking the air extraction channel 2 will affect the air extraction effect at the edge due to the long distance. Multiple air extraction units can be docked with different external air hoods, and multiple fans are used to extract air from the corresponding air extraction units to ensure the suction effect. A docking frame 6 is provided on the top of the air extraction unit, and the docking frame 6 docks with the external air hood.

[0035] A dephosphorization water device is provided above the plate rolling mill. The dephosphorization water device and the dust collecting device are arranged together, which occupies a large space and is inconvenient to inspect and repair because they are close together. Therefore, in one embodiment of the present scheme, a dephosphorization water device is provided in the housing 1, and the dephosphorization water device is integrated into the dust collecting device to reduce the space occupied above the rolling mill.

[0036] The phosphorus removal water device includes a drainage channel 8 and a nozzle 9. The direction of the drainage channel 8 is parallel to the long side of the shell 1. The nozzle 9 is inserted into the drainage channel 8 from the air suction port 4. The shell 1 is provided with a water inlet 10 and a water outlet 11 connected to the drainage channel 8 at both ends. Phosphorus water enters the drainage channel 8 from the water inlet 10 at one end, and water is sprayed into the drainage channel 8 for neutralization and dilution, and then discharged from the water outlet 11 at the other end. In order to improve the structural strength of the drainage channel 8, the cross-section of the drainage channel 8 is triangular, and the drainage channel 8 is arranged against the inner side wall of the shell 1. Specifically, the drainage channel 8 includes an upper plate 12 and a lower plate 13. The upper plate 12 and the upper plate 12 and the inner wall of the shell 1 form the drainage channel 8. The triangular design of the drainage channel 8 utilizes the inner wall of the shell 1 as one side of the triangle, and the other two sides are formed by two plates. The overall structure is simple and easy to process.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
