Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0031] like Figures 1 to 3As shown, the technical solution of this embodiment is applied, and the shielding plate is placed in the air duct 30. The shielding plate includes a first plate body 10 and a second plate body 20. A first seal 14 is provided on the first side of the first plate body 10, and the first seal 14 is sealed with the wall of the air duct 30. A second seal 22 is provided on the first side of the second plate body 20, and the second seal 22 is sealed with the wall of the air duct 30. The second side of the first plate body 10 is detachably connected to the second side of the second plate body 20, and the first plate body 10 and the second plate body 20 are fixed in the air duct 30 to separate the air duct 30.

[0032] In this way, the first plate body 10 and the second plate body 20 are placed in the air duct 30 and connected, so that the air duct 30 can be separated by the shielding plate. When cleaning the drying tower, the shielding plate is used to separate the air duct 30 to prevent the air with droplets of cleaning liquid from continuing to enter the air duct 30, thereby reducing the contact between the cleaning liquid and the pipe wall of the air duct 30 and the filter 50, reducing the possibility of corrosion in the air duct 30, extending the service life of the air duct 30 and the filter 50, and reducing the possibility of foreign matter generated by the corrosion of the filter 50 being blown into the tower body 60 to affect the product quality. In addition, the provision of the first sealing member 14 and the second sealing member 22 improves the sealing between the first plate body 10 and the second plate body 20 and the air duct 30, so that the shielding plate has a better separation effect. The second side of the first plate body 10 is detachably connected to the second side of the second plate body 20, which is convenient for the operator to put the first plate body 10 and the second plate body 20 into the air duct 30 respectively, and then connect the first plate body 10 and the second plate body 20, so that the disassembly and assembly of the shielding plate is more convenient and quick. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that when cleaning the drying tower, the cleaning liquid is easily sprayed into the air duct to cause corrosion.

[0033] In this embodiment, the shielding plate is arranged in the air duct 30 and between the filter 50 and the tower body 60 to reduce the possibility that the cleaning liquid in the tower body 60 enters the filter 50. When the first plate body 10 and the second plate body 20 are fixed in the air duct 30, the shielding plate is adapted to the shape of the cross section of the air duct 30, and the shielding plate completely separates the air duct 30.

[0034] In other embodiments, when the first plate body 10 and the second plate body 20 are fixed in the air duct 30 , the baffle plate is partially adapted to the cross-sectional area of ​​the air duct 30 so that the baffle plate can separate part of the air duct 30 to reduce the amount of cleaning fluid entering the air duct 30 .

[0035] like Figures 1 to 3As shown, the second side of the first plate body 10 overlaps with the second side of the second plate body 20, so that the connection between the first plate body 10 and the second plate body 20 is simpler and faster, and the separation of the first plate body 10 and the second plate body 20 is also convenient. In this embodiment, an air duct diverter is arranged in the air duct 30, and the first plate body 10 and the second plate body 20 are both placed on the air duct diverter, and the second side of the first plate body 10 overlaps with the second side of the second plate body 20 so that they are partially stacked. The air duct diverter is arranged in the air duct 30 and is located between the filter 50 and the tower body 60.

[0036] like Figures 1 to 3 As shown, a third seal is provided on the second side of the first plate body 10, and the third seal is in sealing cooperation with the second side of the second plate body 20. A fourth seal 23 is provided on the second side of the second plate body 20, and the fourth seal 23 is in sealing cooperation with the second side of the first plate body 10. The provision of the third seal and the fourth seal 23 makes the sealing between the second side of the first plate body 10 and the second side of the second plate body 20 better, so that the shielding plate has a better separation effect.

[0037] In other embodiments, a third seal is provided on the second side of the first plate body 10, and the third seal is sealed with the second side of the second plate body 20. Alternatively, a fourth seal 23 is provided on the second side of the second plate body 20, and the fourth seal 23 is sealed with the second side of the first plate body 10.

[0038] like Figures 1 to 3 As shown, the first plate body 10 includes a main board 11 and a flap 12, and the main board 11 is connected to one side of the flap 12 in a flip-able manner. The main board 11 and the flap 12 have simple structures and are easy to process. The flap 12 has a separation state coplanar with the main board 11 and a avoidance state connected to the main board 11 at an angle, and the flap 12 can switch between the separation state and the avoidance state relative to the main board 11. The arrangement of the flap 12 enables the first plate body 10 to be folded, and when the flap 12 is in the avoidance state, it is convenient for the first plate body 10 to enter and exit the air duct 30, making the installation operation of the first plate body 10 simpler and faster. When the flap 12 is in the separation state, it can be coplanar with the main board 11 to separate the air duct 30 to prevent the cleaning liquid from continuing to enter the air duct 30. The first sealing member 14 includes a first sealing section 141 arranged at the edge of the main board 11 and a second sealing section 142 arranged at the edge of the flap 12. The first sealing section 141 and the second sealing section 142 are provided so that when the main board 11 and the flap 12 are coplanar, the first board body 10 can better seal with the wall of the air duct 30 .

[0039] In this embodiment, the second plate body 20 has the same structure as the first plate body 10, and the second sealing member 22 has the same structure as the first sealing member 14. The first sealing member 14, the second sealing member 22 and the third sealing member are all polytetrafluoroethylene sealing members.

[0040] like Figures 1 to 3 As shown, a handle 15 is provided on the main board 11, so that the operator can hold the handle 15 to move the main board 11. When the operator holds the handle 15, the flap 12 is arranged at an angle with the main board 11 under the action of its own gravity to reduce the diameter of the first board body 10, so as to facilitate the first board body 10 to enter and exit the air duct 30.

[0041] like Figures 1 to 3 As shown, the first plate body 10 is a first semicircular plate, and the second plate body 20 is a second semicircular plate. When the second side of the first plate body 10 is connected to the second side of the second plate body 20, the first plate body 10 and the second plate body 20 form a circular plate to separate the air duct 30. The structure of the first plate body 10 and the second plate body 20 is simple, and when the first plate body 10 and the second plate body 20 are connected, they can form a circular plate to adapt to the cross-section of the air duct 30, further improving the separation effect of the shielding plate. In this embodiment, the cross-section of the air duct 30 is a circle that is adapted to the circular plate.

[0042] like Figures 1 to 3 As shown, a first avoidance opening 13 is provided on the second side of the first plate body 10, and a second avoidance opening 21 is provided on the second side of the second plate body 20. When the second side of the first plate body 10 is connected to the second side of the second plate body 20, the first avoidance opening 13 and the second avoidance opening 21 are connected and enclosed to form a avoidance hole. In this way, the setting of the avoidance hole can avoid the pipeline in the air duct 30. The setting of the first avoidance opening 13 and the second avoidance opening 21 facilitates the setting of the first plate body 10 and the second plate body 20 outside the pipeline in the air duct 30, and the operation is simple. In this embodiment, the first avoidance opening 13 is provided on the main board 11.

[0043] The present application also provides an air duct assembly, which includes an air duct 30, and the air duct assembly also includes a shielding plate that is removably disposed in the air duct 30, and the shielding plate is the above-mentioned shielding plate. Since the above-mentioned shielding plate can solve the problem in the related art that when cleaning the drying tower, the cleaning liquid is easily sprayed into the air duct and corrodes, the air duct assembly with the shielding plate can solve the same technical problem.

[0044] like Figures 1 to 3As shown, a manhole 31 is provided on the wall of the air duct 30, and the shielding plate enters into the air duct 30 through the manhole 31. The provision of the manhole 31 facilitates the operator to repair the air duct 30 through the manhole 31. In addition, the operation of placing the shielding plate in the air duct 30 through the manhole 31 is simple, and there is no need to open a separate hole in the air duct 30. The air duct assembly also includes an air duct diverter provided in the air duct 30, and the shielding plate is set on the air duct diverter. The air duct diverter can divert and distribute the wind in the air duct 30. Setting the shielding plate on the air duct diverter makes the installation operation of the shielding plate simpler and faster, thereby improving work efficiency.

[0045] In other embodiments, a manhole 31 is provided on the wall of the air duct 30, and the shielding plate enters the air duct 30 from the manhole 31. Alternatively, the air duct assembly further includes an air duct diverter provided in the air duct 30, and the shielding plate is mounted on the air duct diverter.

[0046] The present application also provides an air duct assembly, which includes an air duct 30. The air duct assembly also includes a baffle plate that can be removed and arranged in the air duct 30 and a powder duct 40 arranged in the air duct 30, and the powder duct 40 is connected to the tower body 60. The baffle plate is the above-mentioned baffle plate, and when the second side of the first plate body 10 is connected to the second side of the second plate body 20, the powder duct 40 is inserted into the avoidance hole. The powder duct 40 can provide powder to the tower body 60. The powder duct 40 is inserted into the avoidance hole so that the baffle plate can avoid the powder duct 40 when separating the air duct 30, which is convenient for the installation of the baffle plate.

[0047] In other embodiments, a fifth sealing member is provided at the edge of the avoidance hole, and the fifth sealing member is in sealing cooperation with the powder pipe 40 .

[0048] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0049] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0050] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
