DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention relates to a raw material extrusion dehydration treatment device for paper mulberry paper processing, such as Figure 1-Figure 2 As shown, the material tank 1 comprises a material tank 1 having a bottom surface and a side wall extending around the bottom surface to form an enclosure.

[0030] On one side of the material pool 1, a vertical frame 2 is arranged perpendicular to the horizontal direction. On the same side of the vertical frame 2 relative to the material pool 1, a driving component 3 with an output end that performs longitudinal reciprocating motion is also connected. The driving component 3 is located directly above the material pool 1. At the same time, the bottom output end of the driving component 3 is connected to a material pressing piece 4 that is adapted to the size of the top opening end of the material pool 1. When the output end of the driving component 3 performs reciprocating motion, the material pressing piece 4 continuously extends into and out of the material pool 1.

[0031] like Figure 2-Figure 3 As shown, a closing limit portion 104 is horizontally arranged along the inner surface of the side wall of the material pool 1. The limit portion 104 is a "mouth"-shaped structure, and a detachable filter element 5 is horizontally mounted thereon so that the filter element 5 is suspended in the material pool 1 and the interior of the material pool 1 is divided into an upper cavity 101 and a lower cavity 102 that are connected up and down.

[0032] Among them, the upper cavity 101 is used to place the paper mulberry bark and is supported by the filter element 5. When the pressing piece 4 extends into the material pool 1 to the maximum stroke, the bottom surface of the pressing piece 4 is close to the top surface of the filter element 5, and the interval is 0.1mm-0.3mm. This distance can not only form a better extrusion for the paper mulberry bark, but also, due to the existence of the interval, there can be an extrusion clearance between the pressing piece 4 and the filter element 5 to prevent the filter element 5 from bending.

[0033] like Figure 3 As shown, the inner wall of the bottom surface of the lower cavity 102 is an inclined structure. When the paper mulberry bark is squeezed and dehydrated, the moisture is filtered out from the filter element 5 and falls into the lower cavity 102. Through the inclined structure of the bottom surface, the moisture is gathered at the lower end of the inclined surface.

[0034] Furthermore, in order to facilitate the discharge of moisture from the lower cavity 102 , a drainage portion 103 connected to the outside of the material pool 1 can be opened at the lower end of the inclined surface of the inclined structure. When moisture accumulates at the lower end of the inclined surface, the squeezed moisture can be discharged to the outside from the drainage portion 103 .

[0035] Furthermore, the water squeezed out of the paper mulberry bark contains bark fiber filaments, which can be used in the pulping operation. Therefore, in this embodiment, the drainage portion 103 is cylindrical, and the inner wall of its water inlet end is provided with a threaded structure. Inside its water inlet end, a filter disc with a pore size smaller than that of the filter element 5 is threadedly connected to filter the bark fiber filaments in the water removed into the lower cavity 102 for secondary utilization. Figure 6 As shown, the filter plate has a cylindrical filter base 1031 that is compatible with the cylindrical structure of the water inlet end of the drain portion 103, and a threaded rib that is compatible with the threaded structure on the inner wall of the water inlet end of the drain portion 103 is provided on the edge of the filter base 1031, so that it can be threadedly connected to the threaded structure of the water inlet end, and it is also convenient for disassembly and assembly.

[0036] like Figure 3 As shown, the driving assembly 3 includes: an outer shell, the top surface of the outer shell is equipped with a driving member 301 electrically connected to an external power supply through a controller through a fastener. In this embodiment, the driving member 301 is preferably a motor, and the output end of the driving member 301 passes through the top surface of the outer shell and is axially connected to a rotating shaft 303 in the outer shell. An axially arranged cylindrical connecting portion 3033 is provided at the top center of the rotating shaft 303. In this embodiment, the output end of the driving member 301 is fixedly connected to the connecting portion 3033 through a coupling to drive the rotating shaft 303 to perform a circular motion along its axial direction;

[0037] Furthermore, in order to increase the torque of the driving member 301 and reduce the rotation speed of the driving member 301, a transmission device 302 can be optionally installed between the driving member 301 and the rotating shaft 303, and the transmission device 302 is connected to the inner wall of the shell body on the other side of the driving member 301. The output end of the driving member 301 is key-connected with the input end of the transmission device 302, and the output end of the transmission device 302 is connected to the cylindrical connecting part 3033 at the top of the rotating shaft 303 through a coupling.

[0038] like Figure 4 As shown, a V-shaped slide rail is provided along the circumferential side of the rotating shaft 303 and is arranged along its axial direction. The V-shaped slide rail includes: a first V-shaped slide rail 3031 and a second V-shaped slide rail 3032 arranged opposite to each other, the starting end of the first V-shaped slide rail 3031 is connected to the end of the second V-shaped slide rail 3032, and the starting end of the second V-shaped slide rail 3032 is connected to the end of the first V-shaped slide rail 3031, so as to form a continuous wavy slideway on the circumferential side of the rotating shaft 303.

[0039] like Figure 5As shown, a movable kit 304 adapted to the rotating shaft 303 is also sleeved on the outside of the rotating shaft 303, and the movable kit 304 also slides through the bottom of the outer shell, wherein the circumferential side of the movable kit 304 is provided with relatively arranged vertical guide grooves 3041 along its movable direction. When the movable kit 304 passes through the bottom of the outer shell, a part of the outer shell is just inside the guide groove 3041. Therefore, the guide groove 3041 can cooperate with the outer shell, so that the movable kit 304 can only move axially but not rotate circumferentially.

[0040] In addition, if Figure 5 As shown, between the movable kit 304 and the rotating shaft 303: the inner wall of the movable kit 304 is also fixedly connected with a relatively arranged connecting piece 306, the connecting piece 306 corresponds to the first V-shaped slide rail 3031 and the second V-shaped slide rail 3032 respectively, and the two groups of connecting pieces 306 can extend into the first V-shaped slide rail 3031 and the second V-shaped slide rail 3032 respectively, and slide along the track, so that the movable kit 304 is sleeved and connected with the rotating shaft 303, and the movable kit 304 can make up and down reciprocating motion by the rotation of the rotating shaft 303. The bottom of the movable kit 304 is fixedly connected to the pressing piece 4 through the connecting column 305.

[0041] Specifically, in the production of paper mulberry paper, the paper mulberry bark after cooking and bleaching is washed and then placed on the filter element 5 in the material pool 1. By starting the driving member 301, the driving member 301 drives the rotating shaft 303 to rotate. Under the action of the V-shaped slide rail provided on the side of the rotating shaft 303, the connecting member 306 on the inner wall of the movable set 304 sleeved on the outside of the rotating shaft 303 slides in the V-shaped slide rail, so that the movable set 304 makes a reciprocating motion up and down in the longitudinal direction. Therefore, the connecting column 305 fixedly connected to the bottom of the movable set 304 will drive the pressing piece 4 at the bottom of the connecting column 305 to move up and down, thereby continuously extending into and out of the upper cavity 101 in the material pool 1, approaching and separating from the filter element 5, thereby effectively carrying the filter element 5 on the filter element 5. The mulberry bark is squeezed and dehydrated, and under the squeezing of the pressing piece 4, the mulberry bark will be further pressed to disperse its fibers, thereby realizing the automatic dehydration and crushing of the mulberry bark. The extracted water will fall from the holes in the filter element 5 into the lower cavity 102, and enter the drainage part 103 along the inclined structure on the bottom surface of the lower cavity 102 to be discharged. At the water inlet end of the drainage part 103, the filter disc will further filter the mulberry bark fibers in the extracted water, so that the fine mulberry bark fibers fall into the lower cavity 102 for temporary storage. These fine mulberry bark fibers can continue to be used in the next pulping operation to reduce waste. Therefore, the present invention effectively reduces labor, improves the production efficiency and quality of mulberry paper, and at the same time reduces the consumption of raw materials and reduces production costs.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
