When the invention is used, the paper fiber is intercepted and recovered when the wet paper seeps out or the squeezed pulp drips the edge of the platform, thereby effectively improving the utilization rate of the paper fiber and reducing the papermaking cost.

Description

Platform slurry intercepting device

Technical Field

The invention belongs to the technical field of papermaking, and particularly relates to a platform slurry intercepting device.

Background

The production process of the rice paper mainly comprises the steps of material selection, pulping, paper fishing, paper drying, inspection, paper cutting and the like. When selecting materials, only wingceltis barks in jing county and straw stalks in rice fields with higher sand content can be used as main raw materials for ensuring the quality of rice paper, the raw material resources are very limited, the pulping process is complicated, and the time period is long, so the utilization rate of finished paper fibers directly influences the production efficiency of the rice paper. After the paper fishing is finished, the fished wet paper is generally stacked on a platform in a stacking manner, and residual moisture on the wet paper can seep out and then flows and drops from the stacking platform; after the quantity of stacked wet paper reaches the requirement, a flat plate cover is used for pressing the stack of wet paper and applying pressure, thereby squeezing out excessive water. The water lost from the wet paper carries the paper fibers away, resulting in waste of paper fibers.

Disclosure of Invention

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

A platform slurry entrapment device comprising a mesh sheet 10 extending outwardly from the edge of the platform a, the mesh size of the mesh sheet 10 being less than the paper fibre size. As shown in fig. 1 and 2, when the wet paper recycling machine is used, slurry seeped or squeezed from wet paper is filtered by the mesh sheet 10 when the slurry drips from the edge of the platform a, paper fibers of the slurry are left on the mesh sheet 10, and the solution drips below the mesh sheet 10, so that the recovery of the paper fibers is realized, the utilization rate of the paper fibers is effectively improved, and the production cost is reduced.

Preferably, the sheets of the mesh 10 are obliquely arranged, and a liquid drainage channel or a liquid collection container is arranged below the mesh 10 at the low position. As shown in fig. 2, the filtered slurry falls into a drainage channel or a liquid collecting container and is sent to the next process.

Specifically, as shown in fig. 2, the mesh 10 is generally in the shape of a slope, which is laterally disposed adjacent to the inner edge and one side edge of the platform a, and is inclined or suspended from the outer edge far from the platform a. The slurry thus filtered will drip off the inclined or overhanging edges of the web 10.

Specifically, the edge of the mesh 10 adjacent to the platform a is connected to the platform a, and the inner edge of the mesh 10 is pressed on the platform a by the pressing plate 31. Therefore, reliable connection between the net piece 10 and the edge of the platform A can be guaranteed, and the phenomenon that paper fibers cannot be intercepted due to gaps left at the connecting edge of the net piece 10 and the platform A is avoided. In other embodiments, the mesh 10 and the platform a may be connected in other manners as long as no gap is formed at the joint between the mesh and the platform a.

Specifically, one side of the mesh sheet 10 is connected with a first rod 21, the first rod 21 makes an extending or shortening movement in the extending direction of the mesh sheet 10 and is limited in displacement by a locking unit, and the side of the mesh sheet 10 is rolled to form a reel which is sleeved on the rod body of the first rod 21. As shown in fig. 1 and 2, the first rod 21 is horizontal. The first rods 21 may also be arranged parallel to the upper surface of the platform a or the press plate 31.

Specifically, the outer end of the first rod 21 is connected with a second rod 22, the height of the other rod end of the second rod 22 is lower than that of the rod end connected with the first rod 21, the second rod 22 is connected with the outer edge of the mesh sheet 10, the length of the rod body of the second rod 22 is consistent with that of the outer edge of the mesh sheet 10, and the side edge of the mesh sheet 10 is rolled to form a reel which is sleeved on the rod body of the second rod 22. As shown in fig. 2, when one side of the mesh sheet 10 is horizontal and the outer end of the other side is free, the second rod 22 can maintain the mesh sheet 10 in a suspended state, so as to prevent the mesh sheet 10 from flying to cause slurry splashing to affect the environment of the production site.

Specifically, the third rod 23 arranged opposite to the first rod 21 is arranged on the other side edge of the mesh sheet 10, the third rod 23 makes extension or contraction movement in the extending direction of the mesh sheet 10 and is limited in displacement by the locking unit, and the side edge of the mesh sheet 10 is turned to form a winding drum to be sleeved on the body of the third rod 23.

In the embodiment shown in FIG. 1, rod three 23 is arranged parallel to rod one 21 and both rods extend outwardly to allow the entire web 10 to be positioned laterally so that the entire underside of the web 10 is the area for solution to drip. Further, in this embodiment, the second rod 22 may not be provided, and the second rod 22 may also be provided to further achieve reliable fixation of the mesh sheet 10.

In the embodiment shown in fig. 2, the first rod 21, the second rod 22 and the third rod 23 are provided, but in practical implementation, the third rod 23 extends out of the platform a by a smaller amount than the first rod 21, so that the mesh 10 is suspended under the action of the second rod 22 at the outer edge of the side where the third rod 23 is located, and thus the solution is guided to the lowest part of the mesh 10 and drips at the lowest part, and the solution is convenient to collect. Further, in this embodiment, the third rod 23 may not be provided as long as the reliable connection of the mesh sheet 10 to the edge of the platform a is ensured.

Preferably, the edge of the platform a, which is provided with the side of the mesh sheet 10, is provided with a guide groove/sleeve 24, the extending direction of the guide groove/sleeve 24 is consistent with the extending direction of the mesh sheet 10, and the first rod 21 and/or the second rod 22 are/is inserted into the guide groove/sleeve 24 and are/is displaced under the guidance of the guide groove/sleeve 24, so that the first rod 21 and/or the second rod 22 are/is reliably installed.

Preferably, a hook is arranged on the table top of the platform A, a hanging hole is correspondingly formed in the rod body of the first rod 21 and/or the second rod 22, and the hook and the hanging hole are in inserted connection and matched to limit the displacement of the corresponding rod body, so that the first rod 21 and/or the second rod 22 can be reliably positioned.
