[0042] The function of the impurity separation component 2 is to filter out the impurities in the pulp. The function of the filtering component 3 is to perform hierarchical filtration on the pulp. The function of the driving component 4 is to drive the filtering component 3 to rotate. The function of the sealing component 5 is to intermittently open and close the feeding port. Feeding ports are provided on the surfaces of the filtering box 1 at the left ends of the primary filtering conveyor belt 31 and the secondary filtering conveyor belt 32. The number of the sealing components 5 is two. Two sealing plates 51 are respectively movably embedded in the ports. Two sealing springs 52 are respectively fixedly connected to the tops of the two sealing plates 51. In the natural state, the elasticity of the sealing spring 52 can apply a pressure to the sealing plate 51, so that the bottom of the sealing plate 51 is connected to the bottom of the port, thereby realizing the sealing of the feeding port. The function of the buffer component 6 is to temporarily store and re-filter the filtered pulp. The function of the extrusion component 7 is to extrude the mud to squeeze out the excess water and drive the sealing plate 51 to intermittently open and close. The number of the extrusion components 7 is two. Grooves are provided on the surfaces of the filtering box 1 at the right ends of the two buffer tanks 61. Two reciprocating threaded rods 71 are respectively rotatably connected inside the two grooves and are respectively connected to the primary filtering conveyor belt 31 and the secondary filtering conveyor belt 32 through the second transmission belt 8 to realize the synchronous rotation of the two reciprocating threaded rods 71.

[0044] One end of the vibrating screen 21 is connected to a vibrating motor. Thus, the pulp is poured onto the vibrating screen 21. The vibrating motor drives the vibrating screen 21 to vibrate, filtering the impurities in the pulp on the top of the vibrating screen 21. The pulp then falls onto the primary filtering conveyor belt 31 and the secondary filtering conveyor belt 32 through the vibrating screen 21. The vibrating screen 21 is in a state of tilting to the right end. Thus, the impurities blocked on the top of the vibrating screen 21 slide along the surface of the vibrating screen 21 and fall into the impurity tank 23 through the outlet 22 for storage.

[0045] The first - stage filtering conveyor belt 31 is movably connected inside the filtering box 1 at the bottom of the vibrating screen 21, and the second - stage filtering conveyor belt 32 is movably connected inside the filtering box 1 at the bottom of the first - stage filtering conveyor belt 31.

[0046] Both the first - stage filtering conveyor belt 31 and the second - stage filtering conveyor belt 32 are composed of a belt meshed on the outer surfaces of two belt pulleys. Different - sized filtering holes are provided on the surface of the belt, thereby realizing the grading filtration of the pulp.

[0047] The first conveyor belt 41 is fixedly connected to the surfaces at the front ends of the first - stage filtering conveyor belt 31 and the second - stage filtering conveyor belt 32, and the driving motor 42 is fixedly connected to the surface of the first conveyor belt 41.

[0048] The first conveyor belt 41 is composed of a belt meshed on the outer surfaces of two belt pulleys. The two belt pulleys are respectively fixedly connected to the front ends of the two belt pulleys at the right ends of the first - stage filtering conveyor belt 31 and the second - stage filtering conveyor belt 32. The driving motor 42 is fixedly connected to the surface of the bottom - middle belt pulley of the first conveyor belt 41. By driving the first conveyor belt 41 to rotate through the driving motor 42, the synchronous rotation of the first - stage filtering conveyor belt 31 and the second - stage filtering conveyor belt 32 is realized.

[0049] The buffer tank 61 is fixedly connected to the outer surface of one end of the filtering box 1, and the filter plate 62 is fixedly installed inside the buffer tank 61.

[0050] The number of the buffer components 6 is two. The two buffer tanks 61 are respectively fixedly connected to the outer surfaces of the two discharging openings at the left end of the filtering box 1. Filtering holes of the same size as those on the surfaces of the first - stage filtering conveyor belt 31 and the second - stage filtering conveyor belt 32 are respectively provided on the surfaces of the two filter plates 62, which can filter the pulp and water.

[0051] The storage tank 91 is fixedly connected to the rear end of the buffer tank 61. The hydraulic rod 92 is fixedly connected to the inside of one end of the storage tank 91, and the push plate 93 is fixedly connected to the other end of the hydraulic rod 92.

[0052] The number of the pulp storage components 9 is two. The right ends of the two storage tanks 91 are respectively fixedly connected to the rear ends of the two buffer tanks 61 and are fixedly connected to the outer surface of the rear end of the filtering box 1. The hydraulic rod 92 is fixedly connected to the connection part between the buffer tank 61 and the storage tank 91. When the extrusion plate 72 pushes the pulp to the rear end and extrudes it into blocks, the hydraulic rod 92 starts to drive the push plate 93 to push the pulp blocks into the storage tank 91 for storage.

[0053] The working principle of a pulp filtering and recycling device for pulp molding provided by the present utility model is as follows:

[0054] First, pour the pulp from the top of the filtration tank 1 onto the surface of the vibrating screen 21. Larger impurities are blocked and fall along the surface of the vibrating screen 21 through the discharge port 22 into the interior of the impurity tank 23. The pulp filtered by the vibrating screen 21 then falls onto the top of the first-stage filtration conveyor belt 31. The driving motor 42 drives the first-stage filtration conveyor belt 31 and the second-stage filtration conveyor belt 32 to rotate synchronously through the first conveyor belt 41. For the pulp that falls onto the top of the first-stage filtration conveyor belt 31, the pulp with larger particles is conveyed by the first-stage filtration conveyor belt 31 to the left end of the first-stage filtration conveyor belt 31 and falls into the interior of the buffer tank 61 through the bottom of the sealing plate 51. Smaller particles fall from the first-stage filtration conveyor belt 31 onto the top of the second-stage filtration conveyor belt 32, and then are filtered again by the second-stage filtration conveyor belt 32 to convey the pulp with small particles to the interior of the bottom buffer tank 61. The moisture is filtered to the bottom of the filtration tank 1. And during this process, the first-stage filtration conveyor belt 31 and the second-stage filtration conveyor belt 32 drive the reciprocating threaded rod 71 to rotate through the second conveyor belt 8. The two pressing plates 72 slide backward in the interiors of the two buffer tanks 61 respectively, and drive the two connecting rods 73 to slide in the interiors of the two connecting sliding grooves 53 respectively. The other ends of the connecting rods 73 give a downward thrust to the sealing plate 51 to push the sealing plate 51 to move downward and block the discharge port at the left end of the filtration tank 1. The pulp on the first-stage filtration conveyor belt 31 and the second-stage filtration conveyor belt 32 accumulates at the left end of the filtration tank 1 and no longer falls into the interior of the buffer tank 61. The pressing plate 72 then pushes the pulp inside the buffer tank 61 until it moves to the rear end to squeeze the pulp and squeeze out the excess moisture. After the squeezing is completed, the pressing plate 72 moves forward to the front end, and the hydraulic rod 92 pushes the push plate 93 to give a thrust to the pulp, and the pulp block is pushed into the interior of the storage tank 91 for storage.

[0055] Compared with the related art, a pulp filtration and recycling device for pulp molding provided by the present utility model has the following beneficial effects:

[0056] The present utility model provides a pulp filtration and recycling device for pulp molding. While the driving assembly 4 can drive the first-stage filtration conveyor belt 31 and the second-stage filtration conveyor belt 32 to rotate to filter the pulp, the second conveyor belt 8 can drive the reciprocating threaded rod 71 to rotate, and the pressing plate 72 can move back and forth to squeeze the pulp that falls into the interior of the buffer tank 61, so as to squeeze out the excess moisture. The squeezed pulp is then stored through the pulp storage assembly 9. While the operation is simple, the concentration and quality of the pulp are improved.

[0057] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present utility model.
