Description

A mist-absorbing hood for the wet end of a paper machine Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, specifically to a mist-absorbing hood for the wet section of a papermaking machine. Background Technology

[0002] The papermaking process generates a large amount of water vapor, which diffuses into the workshop, accumulating and reducing visibility. This results in high temperatures and a sauna-like environment for workers, impacting their efficiency and posing significant safety hazards. Current technology addresses these issues by adding a defogging device to the dehumidification zone, using a fan to draw away the mist from multiple suction ports through negative pressure. However, existing suction ports are mostly circular, limiting their location and number, leading to low extraction efficiency and ineffective removal of mist. Therefore, to overcome the shortcomings of existing technology, improvements are necessary. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a fog-absorbing hood for the wet end of a papermaking machine with high fog absorption efficiency and good fog removal effect.

[0004] This utility model is achieved through the following technical solution:

[0005] A mist-absorbing hood for the wet end of a paper machine includes a hood body, the hood body including two vertically arranged side plates and a guide plate extending downward and outward along the bottom end of the side plates, the side plates forming an elongated mist-absorbing port, and the guide plate forming an elongated guide port.

[0006] Furthermore, the enclosure is equipped with several support and positioning blocks.

[0007] Furthermore, the support positioning block includes a first positioning block and a second positioning block, the first positioning block being disposed at the elongated mist intake port, and the second positioning block pressing against the upper port of the elongated flow guide port.

[0008] Furthermore, the first positioning block and the second positioning block are integrally formed.

[0009] Furthermore, the inner wall of the cover is provided with a snap-fit ​​groove, and the support positioning block snaps into the snap-fit ​​groove.

[0010] Furthermore, the cover also includes mounting plates, which are respectively disposed at the upper ends of the two side plates.

[0011] Furthermore, the mounting plate has a first mounting hole.

[0012] Furthermore, the lower end of the guide plate is provided with a connecting plate, the connecting plate including a first connecting plate extending horizontally outward, a second connecting plate extending upward from the end of the first connecting plate, and a third connecting plate extending horizontally outward from the end of the second connecting plate, the second connecting plate being provided with a second mounting hole.

[0013] Furthermore, the extended end of the third connecting plate has a downwardly extending fourth connecting plate, and the second connecting plate, the third connecting plate and the fourth connecting plate constitute a positioning groove.

[0014] Furthermore, the inner diameter of the elongated mist inlet is 15mm to 20mm.

[0015] Compared with the prior art, the fog suction port of this utility model is a continuous elongated fog suction port, which extends a large range when suctioning fog. The elongated fog suction port is also provided with an elongated guide port that is conducive to collecting fog. After the fog floats upward, it gathers in the elongated guide port. Due to the negative pressure, the fog in the elongated guide port will be continuously drawn out from the elongated fog suction port, resulting in high fog suction efficiency.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As shown in Figures 1 and 2, this utility model discloses a mist-absorbing hood for the wet end of a papermaking machine. The hood body 1 includes two vertically arranged side plates 2 and guide plates 3 extending downwards and outwards from the bottom ends of the side plates 2. The side plates 2 form elongated mist-absorbing inlets 4, and the guide plates 3 form elongated guide inlets 5. The elongated mist-absorbing inlets 4 expand the mist-absorbing range, and the elongated guide inlets 5 gradually expand to both sides, reducing the resistance of mist entering the elongated mist-absorbing inlets 4, resulting in more uniform suction and better mist-absorbing effect.

[0022] The cover 1 contains several supporting positioning blocks 6. Each supporting positioning block 6 includes a first positioning block and a second positioning block. The first positioning block is located at the elongated mist intake 4, and the second positioning block presses against the upper end of the elongated flow guide 5. The first positioning block enhances the structural stability of the elongated mist intake 4, and the second positioning block enhances the structural stability of the elongated flow guide 5. In one specific embodiment, the first and second positioning blocks are integrally formed. The supporting positioning blocks 6 help prevent deformation of the elongated cover 1, resulting in a more stable structure.

[0023] The inner wall of the cover 1 is provided with a snap-fit ​​groove, and the support positioning block 6 is snapped into the snap-fit ​​groove for more stable installation.

[0024] The cover 1 also includes mounting plates 7, which are respectively located on the upper ends of the two side plates 2. The mounting plates 7 have first mounting holes 8 to facilitate the installation of the mounting plates 7 with other components. The mounting plates 7 are used to install the cover 1 onto the mist suction device, facilitating the connection between the elongated mist suction port 4 and the mist suction branch pipe.

[0025] The lower end of the guide plate 3 is provided with a connecting plate 9. The connecting plate 9 includes a first connecting plate 10 extending horizontally outward, a second connecting plate 11 extending upward from the end of the first connecting plate 10, and a third connecting plate 12 extending horizontally outward from the end of the second connecting plate 11. The second connecting plate 11 has a second mounting hole 13. This connecting plate 9 facilitates the connection between two adjacent guide plates 3, and the guide plates are installed and fixed through the second mounting hole 13.

[0026] The third connecting plate 12 has a downwardly extending fourth connecting plate 14 at its extended end. The second connecting plate 11, the third connecting plate 12, and the fourth connecting plate 14 constitute a positioning groove. To enhance the stability of the positioning groove, a plurality of positioning plates 15 are provided inside the positioning groove. These positioning plates 15 serve as reinforcing ribs to strengthen the overall structure of the positioning groove.

[0027] As a preferred implementation method, the inner diameter of the elongated mist inlet 4 is 15mm to 20mm, which results in better mist absorption.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
