Technical Field

[0001] The utility model relates to the field of paper product production, in particular to a net dehydration vacuum device. Background Art

[0002] The wire dewatering vacuum device is a common equipment in papermaking machinery. It is used to dehydrate and dry wet pulp in the papermaking process. Its main principle is to use vacuum suction to extract moisture from the pulp, so that the pulp forms paper on the wire, and the paper is made into finished paper through dehydration and drying processes.

[0003] The existing net dehydration vacuum device dehydrates the paper by extracting the moisture in the paper through the suction of the vacuum pump, but it cannot squeeze the paper to absorb the moisture on the surface of the paper, which easily leads to a longer dehydration time and affects the efficiency of paper dehydration.

[0004] Therefore, it is necessary to design a wire dehydration vacuum device that can squeeze and absorb moisture on the surface of paper, improve the efficiency of moisture absorption on the surface of paper, and improve the dehydration effect of paper. Utility Model Content

[0009] Furthermore, the roller is made of water-absorbing material to absorb moisture from the paper.

[0010] Furthermore, it also includes a scraping mechanism, which includes a material extraction box, a scraper, a torsion spring and a water guide plate. The left side of the sliding frame is connected to the material extraction box, and the right side of the material extraction box is rotatably connected to the scraper. The scraper is in contact with the roller, and two front and rear torsion springs are connected between the scraper and the material extraction box. The front side of the material extraction box is connected to the water guide plate; under the action of the torsion spring, the scraper is close to the roller, and then the roller is scraped, and water flows out from the water guide plate.

[0011] Furthermore, the water guide plate is low in the front and high in the back, so as to facilitate the outflow of water.

[0012] The beneficial effects of the utility model are as follows: 1.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] A vacuum device for dewatering the net part, such as Figure 1-Figure 4 As shown, it includes a base 1, a water suction box 2, a mesh 3, a pipe 4 and a squeezing mechanism 5. Three water suction boxes 2 are connected to the upper side of the base 1. The water suction boxes 2 are made of transparent material. The water suction boxes 2 are all connected to the mesh 3. The front sides of the water suction boxes 2 are all connected to the pipe 4. The water suction boxes 2 are all provided with a squeezing mechanism 5 for squeezing paper to squeeze out water.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, the extrusion mechanism 5 includes a support frame 51, a sliding frame 52, a roller 53, a support block 54 and a telescopic cylinder 55. The front and rear sides of the water suction box 2 are connected to the support frame 51, the upper part of the support frame 51 is slidably connected to the sliding frame 52, and the inner sides of the sliding frame 52 are rotatably connected to the roller 53. The roller 53 is made of water-absorbing material and is in contact with the support frame 51. The outer side of the middle part of the support frame 51 is connected to the support block 54, and the support block 54 is connected to the telescopic cylinder 55. The telescopic end of the telescopic cylinder 55 is connected to the sliding frame 52.

[0023] When it is necessary to dehydrate the paper, the device can be used to put the paper into the clamping net, and then the telescopic cylinder 55 is started, and the sliding frame 52 is driven by the telescopic cylinder 55 to move upward along the support frame 51, and then the roller 53 moves upward. The roller 53 is made of a water-absorbing material, which is convenient for absorbing the moisture on the paper. After moving, the telescopic cylinder 55 is closed, and then the clamping net is placed on the leftmost net strip 3, and then the telescopic cylinder 55 is started, and the sliding frame 52 is driven by the telescopic cylinder 55 to move downward, and then the roller 53 is driven to move downward and contact the clamping net, and then the telescopic cylinder 55 is closed, and then the clamping net is pushed to move to the right. At the same time, it will drive the roller 53 to rotate, thereby squeezing and absorbing the moisture on the surface of the paper, making the paper squeezed more compactly, improving the efficiency of moisture absorption on the surface of the paper, and improving the effect of paper dehydration. When the clamp moves to the rightmost mesh strip 3, an external vacuum pump is connected to the pipeline 4 to extract the moisture in the paper and introduce it into the water suction box 2. The water suction box 2 is made of transparent material, which is convenient for observing the water level, so as to achieve rapid drying of the paper and improve the efficiency of dehydration. After dehydration is completed, the sliding frame 52 is driven to move upward by starting the telescopic cylinder 55, and then the roller 53 moves upward, and then the telescopic cylinder 55 is closed to take out the clamp.

[0024] like Figure 1 and Figure 5 As shown, a scraping mechanism 6 is also included, which includes a material extraction box 61, a scraper 62, a torsion spring 63 and a water guide plate 64. The left side of the sliding frame 52 is connected to the material extraction box 61, and the right side of the material extraction box 61 is rotatably connected to the scraper 62. The scraper 62 is in contact with the roller 53. Two front and rear torsion springs 63 are connected between the scraper 62 and the material extraction box 61. The front side of the material extraction box 61 is connected to a water guide plate 64, and the water guide plate 64 is low in the front and high in the back.

[0025] When the roller rotates to squeeze and absorb the moisture on the surface of the paper, the scraper 62 is pressed against the roller 53 under the action of the torsion spring 63. The roller rotates to make the scraper 62 scrape the roller 53, and the water flows out from the water guide plate 64, thereby scraping off the moisture and impurities on the roller 53, preventing the moisture and impurities from contaminating the paper to be dehydrated, thereby ensuring the quality of the dehydrated paper.

Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
