[0002] Papermaking, also known as papermaking, is one of the four great inventions of ancient my country. Paper is a sheet-like fiber product used for writing, printing, painting or packaging. It is generally made of a water suspension of plant fibers that have been pulped, interlaced on a web, initially dehydrated, compressed and dried. The papermaking industry continues to face various challenges in the process of modern industrialization, but because paper is a product with a very large demand in modern society.

[0003] Considering the increasingly stringent environmental protection requirements, paper can be used in all aspects of life, so it is necessary to continuously produce and strive to obtain production processes or devices that meet more and more environmental protection requirements in the process of advancement. A large amount of wastewater is generated in the existing papermaking industry. Traditional pulp recycling pours chemical agents into papermaking wastewater, causing pulp precipitation. Chemical agents pollute the water, which causes great harm to nature when discharged. At present, the machines on the market are generally unable to recycle and reuse the pulp in the wastewater in an environmentally friendly way. Wastewater carrying pulp is not only not conducive to discharge but also has certain harm to the environment. It causes waste and is not conducive to environmental protection requirements, which increases the cost of papermaking enterprises.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example

[0023] See also Figure 1-Figure 5 As shown, the present embodiment provides an environmentally friendly recovery device for papermaking slurry, including an outer frame 1, a bracket 10 is fixedly connected to the bottom of the outer frame 1, a movable page 11 is rotatably connected to the surface of the outer frame 1, a slide groove 12 is provided on the upper part of the inner surface of the outer frame 1, a through hole is provided on the lower surface of the outer frame 1, a drain port 13 is provided at the through hole, a groove is provided on the lower surface of the outer frame 1, a motor 4 is fixedly connected in the groove, a filter assembly 2 is fixedly connected inside the outer frame 1, the filter assembly 2 includes a centrifugal bucket 23, a counterweight 3 is fixedly connected to the lower surface of the outer frame 1, and the counterweight 3 is used to keep the centrifugal bucket 23 stable when the output shaft of the motor 4 drives the centrifugal bucket 23 to rotate, thereby ensuring the smooth operation of the device.

[0024] The above working principle is: first, connect the device to the power supply, pour the papermaking wastewater from the top of the outer frame 1, when the wastewater is processed by the filter component 2, the pulp is left, and the water flows out of the device from the drain port 13, open the movable page 11, remove the filter component 2, pour out the pulp, and complete the environmentally friendly recycling of the pulp.

[0025] In order to filter out large impurities in wastewater, in this embodiment, the filter component 2 includes a primary filter screen 20, and two sliders 21 are fixedly connected to the side of the primary filter screen 20. The sliders 21 are movably connected to the slide groove 12. The slide groove 12 is used to fix the position of the primary filter screen 20. The primary filter screen 20 is provided with a plurality of through holes of the same size, and the through holes are used to filter impurities. The through holes on the surface of the primary filter screen 20 are slightly larger, and larger impurities cannot pass through the primary filter screen 20, so large impurities can be filtered.

[0026] In order to filter small particle impurities, in this embodiment, the outer frame 1 is located below the primary filter 20 and is slidably connected to a secondary filter 22. The secondary filter 22 is provided with a number of through holes of the same size. The through holes of the primary filter 20 are larger than those of the secondary filter 22. The primary filter 20 filters out large impurities at once, and for the remaining small particle impurities, the through holes on the surface of the secondary filter 22 are smaller, which can meet the passage of pulp and filter out smaller impurities.

[0027] In order to separate the pulp from the water, in this embodiment, the lower surface of the centrifugal bucket 23 is fixedly connected with a rotating seat 24, and the upper surface of a groove at the other end of the rotating seat 24 is fixedly connected. A plurality of through holes are provided on the surface of the centrifugal bucket 23, and the through holes on the surface of the centrifugal bucket 23 are used for drainage. The output shaft of the motor 4 rotates, driving the centrifugal bucket 23 to rotate, and the water is thrown out.

[0028] When the environmentally friendly recycling device for papermaking slag in the present embodiment is used, the movable page 11 is first opened, the primary filter screen 20 and the secondary filter screen 22 are installed into the device along the slide groove 12 in the outer frame 1, the centrifugal bucket 23 is plugged into the rotating seat 24, the movable page 11 is closed, the machine is powered on, and the papermaking wastewater is poured from the top of the outer frame 1 to the primary filter screen 20. After being filtered by the primary filter screen 20, large pieces of impurities remain above the primary filter screen 20, and pulp and the like flow to the secondary filter screen 22. After being filtered by the secondary filter screen 22, the remaining pulp and wastewater remain in the centrifugal bucket 23, and the output shaft of the motor 4 rotates, driving the rapid rotation of the centrifugal bucket 23 to separate the water in the pulp from the pulp, and the separated water flows out along the drain 13, the movable page 11 is opened, the centrifugal bucket 23 is removed, and the pulp is poured out from the centrifugal bucket 23, so that the environmentally friendly recycling of the pulp can be completed.
