Description

Technical Field

[0001] This utility model belongs to the field of dehydration structure technology, and particularly relates to a mesh dehydration structure. Background Technology

[0002] The wire section dewatering structure plays a crucial role in papermaking machines. Its main function is to dewater the formed paper web to a certain degree of dryness. Its efficiency and effectiveness directly affect the dryness, strength, and other physical properties of the paper. The working principle of wire section dewatering mainly relies on the vacuum suction box. When the wire passes through the vacuum suction box, the suction action of the vacuum pump creates a high pressure difference between the top and bottom of the paper, forcibly dewatering the wet paper.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing mesh dewatering structures:

[0004] 1. The top of the structure is open, which makes it easy to lose some suction power during the dehydration process of the net. It is not convenient to add protective measures to the structure to cover the net and reduce the loss of suction power.

[0005] 2. The dehydration structure is wider than the mesh structure, which results in the suction power of the suction holes outside the bottom of the mesh structure being wasted. It is also inconvenient to add sealing measures to the structure to seal off the area outside the mesh structure. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a mesh dewatering structure. This solves the problems of existing structures having an open top, which leads to a loss of suction power during the dewatering process, making it inconvenient to add protective measures to cover the mesh and reduce suction loss; and dewatering structures being wider than the mesh structure, resulting in wasted suction power from the suction holes outside the bottom of the mesh structure, making it inconvenient to add sealing measures to cover the area outside the mesh structure.

[0007] The purpose and effect of the dehydration structure of the mesh part of this utility model are achieved by the following specific technical means:

[0008] A mesh dewatering structure includes a structural body; the structural body is provided with a water-absorbing box panel in the left-right direction, the water-absorbing box panel has suction strip holes arranged vertically and horizontally in the front-back direction, the top end face of the water-absorbing box panel has stepped holes in the top and bottom direction at the four corners, the front and rear end faces of the water-absorbing box panel have vertically through limiting grooves at the left and right ends, the top of the limiting grooves of the water-absorbing box panel is inserted with a left-right shielding cover, the bottom end face of the front and rear walls of the shielding cover has mesh passage grooves that extend from front to back, the bottom end face of the front and rear walls of the shielding cover has insertion blocks at the left and right ends, the bottom end face of the left and right walls of the shielding cover has sealing plate passage grooves that extend from left to right, and the sealing plate passage grooves of the shielding cover have sealing plate fitting grooves that extend from left to right at both ends.

[0009] Furthermore, the outer circumference of both sides of the closed adjustment rod is threaded with left and right directional closed moving plates. The bottom end face of the inner end of the closed moving plate is provided with a guide plate with left and right through threaded holes. The top end face of the closed moving plate is provided with left and right directional upright plates.

[0010] Furthermore, the left and right end faces of the closed adjustment rod are provided with fixing posts, and the outer end face of the fixing posts of the closed adjustment rod is provided with a regular hexagonal prism.

[0011] Furthermore, a left-right closed adjustment rod is installed between the bearing holes of the vacuum water suction box via a bearing, and the outer circumference of the left and right sides of the closed adjustment rod is provided with threads of opposite rotation.

[0012] Furthermore, the top left side wall of the vacuum water suction box is provided with suction screw holes that extend from left to right, and the bottom right side wall of the vacuum water suction box is provided with drain screw holes that extend from left to right.

[0013] Furthermore, the vacuum water suction box is provided with a fixing plate with through holes at the bottom front and back on both the left and right ends, and a bearing hole with through holes is provided at the top center of both the left and right side walls.

[0014] Furthermore, a vacuum water suction box in the left-right direction is installed on the bottom of the water suction box panel by bolts, and threaded blind holes are opened at the four corners of the top end face of the vacuum water suction box.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The convenient protective cover can be inserted into the top of the suction tank panel to cover and protect the mesh. It is convenient to restrict the suction by covering the protective cover to reduce the loss of suction power. This solves the problem that the top of the structure is open, and some suction power is easily lost during the suction and dehydration process of the mesh. It is also inconvenient to add protective measures to the structure to cover the mesh and reduce the loss of suction power.

[0017] The convenient sealing adjustment rod is mounted on the vacuum suction box via bearings to support the sealing moving plate. The convenient sealing moving plate moves synchronously in and out through threaded engagement to seal the suction strip holes on the suction box panel. This solves the problem that when the dehydration structure is wider than the mesh structure, the suction power of the suction holes outside the bottom of the mesh structure is wasted, and it is inconvenient to add sealing measures to the structure to seal off the area outside the mesh structure.

[0025] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides a mesh dewatering structure, including a structural body 1. The structural body 1 is provided with a water absorption box panel 2 in the left-right direction, which facilitates the mesh to pass through the top end face of the water absorption box panel 2. The water absorption box panel 2 has vertically penetrating suction strip holes arranged in the left-right direction to facilitate the suction of water from the mesh for dewatering. The top end face of the water absorption box panel 2 has stepped holes at the four corners, which are vertically penetrating, to facilitate bolt installation on a vacuum water absorption box 4. The front and rear end faces of the water absorption box panel 2 have vertically penetrating limiting grooves at both the left and right ends, which facilitate the insertion and limiting of the protective cover 3. The protective cover 3 in the left-right direction is inserted between the limiting grooves of the water absorption box panel 2 to cover and protect the mesh on the water absorption box panel 2. The bottom end face of the wall is provided with a through groove for the mesh to pass through, which facilitates the passage of the mesh. The bottom end face of the front and rear walls of the shielding cover 3 is provided with an insertion block at both ends, which facilitates insertion into the limiting groove of the water absorption box panel 2. The bottom end face of the left and right walls of the shielding cover 3 is provided with a through groove for the sealing plate to pass through, which facilitates the passage of the sealing moving plate 6. The sealing plate through groove of the shielding cover 3 is provided with a through groove for the sealing plate to pass through, which facilitates the passage of the upright plate of the sealing moving plate 6. The bottom of the water absorption box panel 2 is bolted to a vacuum water absorption box 4 in the left and right direction, which facilitates the collection of water from the mesh and the support of various components. The top end face of the vacuum water absorption box 4 is provided with threaded blind holes at the four corners, which facilitates the installation of the water absorption box panel 2 with bolts.

[0029] The vacuum water suction box 4 has fixing plates with through holes at the bottom of both the left and right ends, facilitating bolt fixing. The top center of both the left and right side walls of the vacuum water suction box 4 has through bearing holes for the installation of the sealing adjustment rod 5 via bearings. The top center of the left side wall of the vacuum water suction box 4 has through suction screw holes for the installation of the suction pipe via threads. The bottom center of the right side wall of the vacuum water suction box 4 has through drain screw holes for the installation of the drain pipe via threads. The sealing adjustment rod 5 is mounted between the bearing holes of the vacuum water suction box 4 via bearings, allowing it to rotate. The outer circumference of the left and right sides of the sealing adjustment rod 5 has rotational... The opposite threads facilitate the synchronous inward or outward movement of the closing moving plate 6 through thread engagement. The left and right ends of the closing adjusting rod 5 are each equipped with a fixing post for easy installation via bearings. The outer end face of the fixing post of the closing adjusting rod 5 is provided with a regular hexagonal prism for easy rotation using tools. The left and right outer circumferences of the closing adjusting rod 5 are threadedly fitted with left and right directional closing moving plates 6, facilitating synchronous inward or outward movement of the closing moving plates 6 through thread engagement. The bottom end face of the inner end of the closing moving plate 6 is provided with a guide plate with left and right through threaded holes, facilitating the threaded installation of the closing adjusting rod 5. The top end face of the closing moving plate 6 is provided with left and right directional vertical plates, facilitating the closure of the mesh portion of the protective cover 3 through the groove.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In this utility model, such as Figure 1 As shown, the top end face of the water suction tank panel 2 has a mesh section in the middle. Both the front and rear ends of the mesh section are cut off, and the mesh section is located between the closed moving plates 6. When... Figure 1 As shown, when the main body 1 is in use, the vacuum suction box 4 is fixed with bolts, the suction pipe is threaded onto the suction screw hole of the vacuum suction box 4, and the drain pipe is threaded onto the drain screw hole of the vacuum suction box 4. The external suction device is turned on, so that the suction force is transmitted to the inside of the vacuum suction box 4 through the suction pipe, and then acts on the mesh part through the suction strip hole of the suction box panel 2, thereby realizing the suction and dehydration of the mesh part. The suctioned water will fall into the vacuum suction box 4 and be discharged from the drain pipe. At the same time, the movable plate 6 is closed to the bottom of the mesh part. The suction strip hole portion of the suction tank panel 2 is sealed off, so that the suction force is only applied to the mesh section, preventing the waste of suction force. At the same time, the top of the mesh section is covered and restrained by the protective cover 3, thereby reducing the loss of suction force. In addition, the spacing between the closed moving plates 6 can be adjusted according to the width of the mesh section. When adjusting the spacing between the closed moving plates 6, the closing adjustment rod 5 is rotated by a tool to engage with the threaded engagement of the closed moving plates 6, so that the closed moving plates 6 move inward or outward synchronously through the threaded engagement, thereby realizing the adjustment of the spacing between the closed moving plates 6.

[0032] Example 2:

[0033] The difference from Embodiment 1 is that the top end face of the fixing plate of the vacuum water suction box 4 can also be set as a frosted surface, thereby increasing the friction between the top end face of the fixing plate of the vacuum water suction box 4 and the fixing bolt, and preventing the fixing bolt from rotating and loosening.

[0034] Example 3:

[0035] The difference from Embodiment 1 is that the regular hexagonal prism of the closing adjustment rod 5 can also be set as a regular heptagonal prism, thereby requiring a special tool that works with the regular heptagonal prism to rotate the closing adjustment rod 5, preventing non-staff members from rotating and adjusting the closing adjustment rod 5.
