A papermaking waste recycling device

Abstract

The utility model relates to the field of papermaking, and in particular to a papermaking waste recovery device. When the pressing plate squeezes the fiber pulp on the filter plate, part of the fiber pulp will not be squeezed into the filter plate hole, but will be mixed with impurities and sandwiched in the area between the filter plate and the pressing plate. The utility model provides a papermaking waste recovery device, including a box body, etc. The pressing plate and the pressing block are moved downward by controlling the electric push rod I, so that the pressing block squeezes the residue and impurities at the interval of the filter hole I. Since the cross-section of the pressing block is an inverted triangle, the pressing block guides the residue and impurities and squeezes the residue and impurities toward the filter hole I, thereby allowing the smaller fiber pulp residue to enter the filter hole I, while the larger impurities are blocked by the filter screen, thereby improving the separation efficiency of the fiber pulp and impurities.

Description

Technical Field

[0001] The utility model relates to the field of papermaking, in particular to a waste material recovery device for papermaking. Background Art

[0002] After being processed, waste paper can be re-formed into a state of fiber pulp, and then gradually processed to make base paper such as kraft paper. In the prior art, for example, Chinese patent (CN212294175U) discloses a papermaking waste recovery device, which can improve the filtration efficiency of fiber pulp through a pressing plate, avoid the problem that high-concentration fiber pulp is filtered slowly and affects the filtration efficiency, and realizes the separate collection and treatment of pure fiber pulp and waste impurities through different outlets.

[0003] However, when the pressing plate squeezes the fiber pulp on the filter plate, part of the fiber pulp will not be squeezed into the filter plate holes, but will be mixed with impurities and sandwiched in the area between the filter plate and the pressing plate, resulting in poor separation effect. Utility Model Content

[0004] In order to overcome the disadvantage that when the pressing plate squeezes the fiber pulp on the filter plate, part of the fiber pulp is not squeezed into the filter plate holes, but is mixed with impurities and sandwiched in the area between the filter plate and the pressing plate, the utility model provides a papermaking waste recovery device.

[0005] The utility model is implemented by the following technical solutions:

[0006] A papermaking waste recycling device comprises a box body; it also comprises a filter plate I, an electric push rod I, a pressure plate, a pressure block, a filter screen, an electric push rod II, a push plate I, a rotating plate I, and a collecting bucket I; the box body is fixedly connected with the filter plate I; the filter plate I is provided with a plurality of filter holes I; the box body is fixedly connected with the electric push rod I; the telescopic end of the electric push rod I is fixedly connected with the pressure plate; a plurality of pressure blocks with inverted triangular cross sections are fixedly connected to the lower side of the pressure plate, and the pressure blocks are located above the intervals of the filter holes I; each filter hole I is fixedly connected with a filter screen; the box body is fixedly connected with the electric push rod II; the telescopic end of the electric push rod II is fixedly connected with the push plate I, and the push plate I is located in the box body in the initial state; the box body is rotatably connected with the rotating plate I, and a torsion spring is provided between the rotating plate I and the box body; the box body is fixedly connected with the collecting bucket I, and the collecting bucket I is located below the rotating plate I.

[0007] Preferably, it also includes filter plate II, electric push rod IV, push plate II, rotating plate II and collecting bucket II; the box is connected to filter plate II; filter plate II is provided with a plurality of filter holes II; the box is fixedly connected to electric push rod IV; the telescopic end of electric push rod IV is fixedly connected to push plate II, and in the initial state, push plate II is located in the box, and push plate II is located between filter plate I and filter plate II; the box is rotatably connected to rotating plate II, and a torsion spring is provided between rotating plate II and the box; the box is fixedly connected to collecting bucket II, and collecting bucket II is located below rotating plate II.

[0008] Preferably, it also includes an electric push rod III and a spring rod; the box is slidably connected to the filter plate II; the box is fixedly connected to a plurality of two electric push rods III, and the telescopic ends of all the electric push rods III are commonly fixedly connected to the filter plate II; the filter plate II is fixedly connected to a plurality of spring rods, and the telescopic ends of the spring rods are fixedly connected to the filter plate I.

[0009] Preferably, it also includes a poking rod; the filter plate II is fixed with a plurality of rubber poking rods, and the poking rods cooperate with the filter hole I; the push plate II is provided with a plurality of rectangular grooves, and the rectangular grooves cooperate with the poking rods.

[0010] Preferably, the filter plate II is arranged in an arc shape with the middle portion being lower than the two sides.

[0011] Preferably, filter holes I and filter holes II are arranged alternately.

[0012] The beneficial effects of the utility model are as follows: by controlling the electric push rod I to move the pressing plate and the pressing block downward, the pressing block squeezes the residue and impurities at the interval of the filter hole I. Since the cross section of the pressing block is an inverted triangle, the pressing block guides the residue and impurities and squeezes the residue and impurities toward the filter hole I, thereby allowing the smaller fiber pulp residue to enter the filter hole I, while the larger impurities are blocked by the filter screen, thereby improving the separation efficiency of the fiber pulp and impurities.

[0013] The impurities and fiber pulp passing through the filter hole I fall onto the filter plate II. Since the filter holes I and II are staggered, the fiber pulp and impurities will not fall directly into the filter hole II after entering the filter hole I. Moreover, since the filter plate II is arranged in an arc shape with the middle part lower than the two sides, the fiber pulp and impurities will flow along the arc filter plate II to the middle part of the filter plate II under the action of their own gravity, and then the fiber pulp and impurities will be filtered twice through the filter hole II to improve the filtering effect.

[0022] It also includes filter plate II1011, electric push rod IV1014, push plate II1015, rotating plate II1016 and collecting bucket II1017; the box body 1 is connected with filter plate II1011; the filter plate II1011 is provided with a plurality of filter holes II1011a; the box body 1 is bolted with electric push rod IV1014; the telescopic end of the electric push rod IV1014 is fixedly connected with push plate II1015, and in the initial state, the push plate II1015 is located in the box body 1, and the push plate II1015 is located between the filter plate I101 and the filter plate II1011; the box body 1 is rotatably connected with rotating plate II1016, and a torsion spring is provided between the rotating plate II1016 and the box body 1; the box body 1 is fixedly connected with collecting bucket II1017, and the collecting bucket II1017 is located below the rotating plate II1016.

[0023] It also includes an electric push rod III1010 and a spring rod 1012; the box body 1 is slidably connected to the filter plate II1011; the box body 1 is bolted with a plurality of two electric push rods III1010, and the telescopic ends of all the electric push rods III1010 are fixedly connected to the filter plate II1011; the filter plate II1011 is fixedly connected to four spring rods 1012, and the telescopic ends of the spring rods 1012 are fixedly connected to the filter plate I101.

[0024] It also includes a poking rod 1013; the filter plate II 1011 is fixedly connected with a plurality of poking rods 1013 made of rubber material, and the poking rods 1013 cooperate with the filter hole I 101a; the push plate II 1015 is provided with a plurality of rectangular grooves 1015a, and the rectangular grooves 1015a cooperate with the poking rods 1013.

[0025] The filter plate II 1011 is arranged in an arc shape with the middle portion being lower than the two sides.

[0026] The filter holes Ⅰ101a and the filter holes Ⅱ1011a are arranged alternately.

[0027] When in use, the external pump is connected to the feed port at the rear side of the box body 1, and then the external pump is controlled to start, and the fiber pulp is sent to the filter plate Ⅰ101 in the box body 1 through the feed port. The filter plate Ⅰ101 filters the fiber pulp. After all the fiber pulp enters the box body 1, the external pump is controlled to stop feeding to the feed port. At this time, there are more fiber pulp residues and impurities on the filter plate Ⅰ101. Then, the electric push rod Ⅰ102 is controlled to move the pressing plate 103 and the pressing block 104 downward, so that the pressing block 104 squeezes the residues and impurities at the interval of the filter hole Ⅰ101a. Since the cross section of the pressing block 104 is an inverted triangle, the pressing block 104 can squeeze the residues and impurities. The fiber pulp is guided to squeeze the residue and impurities to the filter hole Ⅰ101a, so that the smaller fiber pulp residue enters the filter hole Ⅰ101a, while the larger impurities are blocked by the filter screen 105, thereby improving the separation efficiency of the fiber pulp and impurities. After passing through the filter plate Ⅰ101, the fiber pulp falls onto the inclined surface on the lower side of the inner side of the box body 1, and finally flows out from the discharge port on the lower right side of the box body 1. Subsequently, the electric push rod Ⅱ106 is controlled to drive the push plate Ⅰ107 to move to the left, and then the push plate Ⅰ107 pushes the impurities remaining on the filter plate Ⅰ101 to the rotating plate Ⅰ108. The rotating plate Ⅰ108 flips upward under the action of the torsion spring, and then the impurities fall into the collecting bucket Ⅰ109 for collection.

[0028] Some impurities will follow the fiber pulp through the filter hole Ⅰ101a. At this time, the impurities and fiber pulp passing through the filter hole Ⅰ101a fall onto the filter plate Ⅱ1011. Since the filter holes Ⅰ101a and Ⅱ1011a are staggered, the fiber pulp and impurities will not directly fall into the filter hole Ⅱ1011a after entering the filter hole Ⅰ101a, and since the filter plate Ⅱ1011 is arranged in an arc shape with the middle lower than the two sides, the fiber pulp and impurities will flow along the arc filter plate Ⅱ1011 to the middle of the filter plate Ⅱ1011 under the action of their own gravity, and then the fiber pulp and impurities will be filtered twice through the filter hole Ⅱ1011a to improve the filtering effect, and the impurities passing through the filter hole Ⅰ101a will be intercepted again by the poking rod 1013 to prevent the impurities from following the fiber pulp. The pulp passes through the filter hole Ⅱ1011a. At the same time, the electric push rod Ⅲ1010 is controlled to drive the filter plate Ⅱ1011 and the poking rod 1013 to move vertically back and forth, so that the poking rod 1013 pokes the filter hole Ⅰ101a, and pokes down the fiber pulp blocked in the filter hole Ⅰ101a. At this time, there will be more impurities remaining on the filter plate Ⅱ1011. The electric push rod Ⅳ1014 is controlled to make the push plate Ⅱ1015 move forward, and the rubber poking rod 1013 undergoes adaptive deformation and passes through the rectangular groove 1015a, and then the push plate Ⅱ1015 pushes the impurities remaining on the filter plate Ⅱ1011 and the impurities hanging on the poking rod 1013 to the rotating plate Ⅱ1016. The rotating plate Ⅱ1016 rotates upward under the torsion spring, and then the impurities fall into the collecting bucket Ⅱ1017 for collection.

[0029] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. The scope of the following claims is to be accorded the broadest interpretation so as to encompass all modifications and equivalent structures and functions.
