Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a pulping and mixing device. Background Technology

[0002] Waste paper processing is the process of reprocessing recycled waste paper to obtain qualified fibers for the production of paper products. The recycling and utilization of waste paper is beneficial to environmental protection, forest conservation, and resource conservation. Waste paper can be reused multiple times.

[0003] When recycling waste paper, it needs to go through steps such as crushing, pulping, impurity removal, slag removal, deinking, thickening, bleaching, and washing. In the pulping step, the pulp is usually pre-mixed to facilitate subsequent pulping. However, due to the poor fluidity of the pulp, traditional mixing equipment is prone to insufficient mixing when mixing the pulp. Some pulp tends to accumulate at the bottom of the mixing tank and cannot participate in the mixing effectively, which affects the subsequent pulping and the quality of the paper.

Detailed Implementation

[0026] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figs. 1 to 4 As shown, a pulping and mixing device of the present invention includes a mixing tank 5, a pressing mechanism and a mixing mechanism. The pressing mechanism is installed on the upper part of the mixing tank 5, and the mixing mechanism is connected to the pressing mechanism. The mixing tank 5 has a feed inlet on both sides of the upper part and a discharge outlet at the lower part.

[0028] The pressing mechanism includes a gantry frame 2, a telescopic drive component 1, a lifting plate 4, a connecting pipe 11, a lifting frame 15, a connecting rod 16, and an extrusion screen 17. The gantry frame 2 is installed on the top of the mixing tank 5. The telescopic drive component 1 is installed on the gantry frame 2 and is linearly driven connected to the lifting plate 4. The upper part of the mixing mechanism is connected to the lifting plate 4, and the lower part of the mixing mechanism is located inside the mixing tank 5. The upper part of the connecting pipe 11 is fixedly connected to the lifting plate 4, the middle part of the connecting pipe 11 is slidably connected to the mixing tank 5, and the lower part of the connecting pipe 11 is fixedly connected to the lifting frame 15. The lifting frame 15 is connected to the extrusion screen 17 through the connecting rod 16. The extrusion screen 17 is slidably connected to the inner surface of the mixing tank 5, and a plurality of material passage holes are evenly arranged on the extrusion screen 17.

[0029] The working principle of this utility model is as follows: When it is necessary to pre-mix the pulp in the actual papermaking process, the pulp can be introduced into the interior of the mixing tank 5 through the feed port. Then, the mixing mechanism is run to mix the pulp. At the same time, the telescopic drive 1 is run to drive the lifting plate 4 to descend. Simultaneously, the lifting plate 4 drives the lifting frame 15 to descend through the connecting pipe 11. The lifting frame 15 drives the extrusion screen 17 to descend through the connecting rod 16. The extrusion screen 17 squeezes the pulp at the bottom of the mixing tank 5, causing the pulp at the bottom of the mixing tank 5 to pass through the extrusion screen 17 and move upward. The mixing mechanism then fully mixes the pulp.

[0030] Furthermore, it also includes a guide pipe 10, which is fixedly connected to the top of the mixing tank 5, and the connecting pipe 11 passes through the interior of the guide pipe 10 and is slidably connected.

[0031] As can be seen from the above description, it is beneficial to guide the connecting pipe 11 through the guide pipe 10, so that the connecting pipe 11 is more stable when it is raised and lowered.

[0032] Furthermore, the stirring mechanism includes a rotating drive component 3, a drive shaft 12, a rotating disk 19, and stirring components 13. The rotating drive component 3 is mounted on the lifting disk 4. The drive shaft 12 passes through the interior of the connecting pipe 11 and is rotatably connected. The rotating drive component 3 is drivenly connected to one end of the drive shaft 12. The rotating disk 19 is disposed inside the stirring tank 5. The other end of the drive shaft 12 is connected to the rotating disk 19. Several stirring components 13 are fixedly connected to the outer side of the rotating disk 19.

[0033] As can be seen from the above description, when it is necessary to stir the pulp, the rotating drive 3 can be operated, so that the rotating drive 3 drives the rotating disk 19 to rotate through the drive shaft 12. The rotating disk 19 stirs the pulp through the stirring component 13, while the drive shaft 12 rotates in the connecting pipe 11.

[0034] Furthermore, the gantry frame 2 is provided with a clearance hole 8, which is used to avoid the rotation drive component 3.

[0035] As can be seen from the above description, it is beneficial to avoid the gantry frame 2 affecting the lifting and lowering of the rotating drive component 3 by using the clearance hole 8.

[0036] Furthermore, a scraper ring 18 is fixedly connected to the outer side of the extrusion screen 17.

[0037] As can be seen from the above description, it is beneficial to scrape the slurry on the inner wall of the mixing tank 5 by scraping the scraper ring 18.

[0038] Furthermore, it also includes a feed pipe 7, which is fixedly connected to a feed inlet, and each feed pipe 7 is provided with a cover.

[0039] As can be seen from the above description, it is advantageous to introduce the slurry into the interior of the mixing tank 5 through the feed pipe 7, and to seal the feed pipe 7 through the cover.

[0040] Furthermore, it also includes a discharge pipe 9, which is fixedly connected to the discharge port, and a valve body 14 is provided inside the feed pipe 7.

[0041] As can be seen from the above description, it is beneficial to discharge the pulp through the discharge pipe 9, and the discharge pipe 9 can be sealed by the valve body 14.

[0042] Furthermore, it also includes a support frame 6, which is fixedly connected to the bottom of the mixing tank 5.

[0043] As can be seen from the above description, it is beneficial to support the entire device through the support frame 6.

[0044] Furthermore, it also includes a controller, which is electrically connected to both the pushing mechanism and the stirring mechanism.

[0045] As can be seen from the above description, it makes it more convenient for users to control the overall device.
