Description

Technical Field

[0001] The utility model relates to the technical field of papermaking slurry processing, in particular to a circulation processing device for papermaking slurry. Background Art

[0002] Papermaking waste pulp is an important raw material for paper production. In order to save raw materials, papermaking waste pulp is generally recycled and requires special treatment before recycling.

[0003] The Chinese utility model patent, with the authorization announcement number "CN216474237U," specifically refers to a "circulation treatment device for papermaking slurry," which rapidly dries filtered fiber material by blowing air into a collection box.

[0004] The above device filters large particles of impurities in the papermaking slurry by tilting two layers of filter screens that are distributed up and down and have different mesh apertures, but the filter screen is not vibrated or shaken. It only uses the tilted design of the filter screen to achieve filtration by the gravity of the papermaking slurry itself. Its filtering effect is obviously insufficient. This is because the papermaking slurry itself has a certain humidity. The papermaking slurry with smaller particles that should fall from the filter screen mesh easily stick together, making it difficult to fall from the filter screen mesh. Instead, they will roll down from the filter screen surface together with large particles of impurities, reducing the filtering effect. In addition, large particles of impurities may adhere to the surface of the filter screen and will not fall out, thereby clogging the filter screen mesh, reducing the filtering efficiency. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a circulating treatment device for papermaking slurry, which can effectively solve the problems raised in the background technology.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a circulation treatment device for papermaking slurry, comprising a treatment box and a hopper installed on the top of the treatment box and connected to the treatment box, a baffle is fixedly installed on the inner cavity wall of one side of the treatment box, and a first discharge port and a second discharge port arranged in parallel are opened through the inner cavity at the bottom of the treatment box, and a filter assembly comprises a rotating roller rotatably installed in the center of the inner cavity of the treatment box, a filter box is twisted on the outer roller wall of the rotating roller, and a filter screen is embedded and fixedly installed at the bottom opening passing through the upper and lower parts of the filter box, and a rotating rod that is rotatably installed on the side of the filter box away from the rotating roller and is toggled with the baffle, a fan is fixedly installed on the outer side wall of the treatment box, and an output end of the fan is arranged below the inner cavity wall of the treatment box away from the baffle and closer to the second discharge port.

[0008] Further, two support frames arranged side by side are fixedly installed at the bottom of the processing box, and a triangular prism protrusion located between the first blanking port and the second blanking port is installed at the bottom of the inner cavity of the processing box.

[0009] Further, the filtering assembly further includes a motor fixedly installed on the outer side wall of the processing box, with its output end extending into the processing box and fixedly connected to one end of the rotating roller. Two fixedly arranged fixing bars are perpendicularly fixedly installed on the outer roller wall of the rotating roller.

[0010] Further, rotating shafts rotatably installed with the corresponding fixing bars are perpendicularly fixedly installed at the centers of both ends of the filtering box. Torsion springs are sleeved on the outer shaft walls of the rotating shafts. One end of each torsion spring is fixedly connected to the filtering box, and the other end is fixedly connected to the corresponding fixing bar.

[0011] Further, a mounting seat is fixedly installed on the side of the filtering box away from the rotating roller, and the rotating rod is rotatably installed between the two opposite inner side walls of the mounting seat.

[0012] Further, a paper-making slag pulp collection bucket opposite to the position of the first blanking port and a slag material collection bucket opposite to the position of the second blanking port are respectively arranged below the processing box. A plurality of exhaust holes distributed in a rectangular array are formed through the lower bottom at the bottom of the inner cavity of the paper-making slag pulp collection bucket. Handles are installed at one end of both the paper-making slag pulp collection bucket and the slag material collection bucket, and universal wheels are installed at the bottom.

[0013] The technical solution provided by the present utility model has the following beneficial effects compared with the known prior art:

[0014] 1. First, a rotating roller is rotatably installed in the processing box, and a filtering box for filtering paper-making slag pulp is torsionally connected to the outer roller wall of the rotating roller. During the rotation of the filtering box, it will contact the stop bar fixedly installed on the inner side wall of the processing box, thereby generating radial vibration around the rotating shaft, increasing the shaking effect of the paper-making slag pulp in the filtering box, making the mutually adhered paper-making slag pulp shake and disperse, facilitating it to fall through the mesh holes of the filter net, improving the filtering effect. And when the filtering box rotates 180°, the opening is vertically downward, facilitating the discharge of all the remaining large-particle impurities after filtration from the filtering box, preventing the blockage of the filter net holes, and improving the filtering efficiency;

[0015] 2. A blower is arranged on the inner side wall of the processing box. By blowing air with the blower, not only can the air flow efficiency in the processing box be improved, thereby improving the drying effect of the paper-making slag pulp, but also the small amount of paper-making slag pulp that fails to fall through the mesh holes of the filter net can be blown back into the paper-making slag pulp collection bucket, further improving the filtering effect. And because the large-particle impurities are heavier and are less affected by the blowing and fall into the slag material collection bucket, classified collection is realized.

Detailed implementation manners

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0023] The following further describes the present invention with reference to the embodiments.

[0024] Embodiment 1

[0025] Refer to Figures 1-4, which is the first embodiment of the utility model, discloses a circulating treatment device for papermaking slurry, including a treatment box 1, and a hopper 14 installed on the top of the treatment box 1 and connected to the treatment box 1, a retaining bar 11 is fixedly installed on the inner wall of one side of the treatment box 1, and a first discharge port 12 and a second discharge port 13 arranged in parallel are opened through the inner cavity of the bottom of the treatment box 1, and a filter assembly includes a rotating roller 22 rotatably installed at the center of the inner cavity of the treatment box 1, and a filter box 24 is twisted on the outer roller wall of the rotating roller 22, and the filter box 24 is fixedly embedded in the bottom opening of the upper and lower parts. A filter screen 25 is installed, and the filter screen 25 matches the aperture opened through the filter box 24 to avoid dead corners in filtration. A rotating rod 29 that is rotatably installed on the side of the filter box 24 away from the rotating roller 22 and is moved by the baffle 11. The fan 3 is fixedly installed on the outer wall of the processing box 1, and the output end of the fan 3 is arranged below the inner cavity wall of the processing box 1 away from the baffle 11, and closer to the second discharge port 13. Therefore, the air blown by the fan 3 can make a small amount of lighter papermaking slurry be blown a longer distance, and thus return to the papermaking slurry collection barrel 4.

[0026] Example 2

[0027] Reference Figures 1-4 , which is the second embodiment of the present utility model. This embodiment is different from the first embodiment in that: two supporting frames 15 arranged in parallel with each other are fixedly installed at the bottom of the processing box 1, and a triangular prism protrusion is installed at the bottom of the inner cavity of the processing box 1 between the first discharge port 12 and the second discharge port 13 to prevent a small amount of papermaking slurry from remaining at the bottom of the inner cavity of the processing box 1. The filter assembly also includes a motor 21 fixedly installed on the outer wall of the processing box 1, with the output end extending into the processing box 1 and fixedly connected to one end of the rotating roller 22. Two fixed bars 23 arranged in parallel are vertically fixedly installed on the outer roller wall of the rotating roller 22. The centers of both ends of the filter box 24 are vertically fixed with rotating shafts 26 rotatably mounted with the corresponding fixing bars 23. The outer shaft walls of the rotating shafts 26 are all fitted with torsion springs 27. One end of the torsion spring 27 is fixedly connected to the filter box 24, and the other end is fixedly connected to the filter box 24. One end is fixedly connected to the corresponding fixing bar 23, and the filter box 24 is fixedly installed on the side away from the rotating roller 22. The mounting seat 28 is fixedly installed, and the rotating rod 29 is rotatably installed between the two opposite inner walls of the mounting seat 28. The rolling contact between the rotating rod 29 and the baffle 11 can reduce the wear of the baffle 11, which is conducive to long-term use. A papermaking slurry collection bucket 4 opposite to the first discharge port 12 and a slag collection bucket 5 opposite to the second discharge port 13 are respectively provided below the processing box 1. The bottom of the inner cavity of the papermaking slurry collection bucket 4 is penetrated through the lower bottom to provide a number of exhaust holes 41 distributed in a rectangular array, which guide the airflow in the processing box 1 to be discharged from the exhaust holes 41, ensuring that the fan 3 can blow air stably for a long time. The papermaking slurry collection bucket 4 and the slag collection bucket 5 are both equipped with handles 6 at one end, and universal wheels 7 are installed at the bottom to facilitate pushing and pulling to move the position.

[0028] The remaining structure is the same as that of Embodiment 1.

[0029] The working process of the present utility model is as follows:

[0030] First, pour the papermaking slag pulp from the hopper 14 into the processing box 1. Due to gravity, the papermaking slag pulp will directly fall into the filter box 24. At this time, start the motor 21 to drive the rotating roller 22, that is, the two fixing bars 23 and the filter box 24 to swing reciprocally, so that the rotating rod 29 on one side of the filter box 24 continuously toggles the stop bar 11 on the inner wall of the processing box 1. Since the filter box 24 and the corresponding two fixing bars 23 are connected by a torsion spring 27, the filter box 24 together with the papermaking slag pulp inside generates a radial reciprocating swing around the rotating shaft 26, making the mutually adhered papermaking slag pulp shake and disperse, facilitating it to fall through the mesh holes of the filter net 25, improving the filtering effect. The fallen papermaking slag pulp will directly pass through the first discharge port 12 and enter the papermaking slag pulp collection bucket 4;

[0031] Secondly, after waiting for a certain period of time, when it is observed that no more papermaking slag pulp continues to fall into the papermaking slag pulp collection bucket 4, start the motor 21 to drive the rotating roller 22, that is, the filter box 24 to rotate 180°. The large particle impurities and a small amount of papermaking slag pulp originally filtered and intercepted in the filter box 24 will also rotate 180° synchronously. Due to the lack of support, the large particle impurities and a small amount of papermaking slag pulp will fall. At this time, start the blower 3 to blow air, which can not only improve the air flow efficiency in the processing box 1, thereby improving the drying effect of the papermaking slag pulp, but also blow the small amount of papermaking slag pulp with a lighter mass than the large particle impurities back to the papermaking slag pulp collection bucket 4, further improving the filtering effect. Since the large particle impurities are heavier and are less affected by the blowing and fall into the slag material collection bucket 5, classified collection is achieved.

[0032] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present utility model.
