[0001] The utility model relates to the technical field of solid waste treatment, in particular to a wet solid waste treatment device. Background Art

[0002] The products in the form of felt or paper sheets produced by wet forming technology with chopped glass fiber or mineral wool as the main raw materials are collectively referred to as glass fiber wet products. The production method of glass fiber wet products is usually as follows: the main raw materials are dispersed into a fiber suspension of a certain concentration by pulping, the pulp is mixed with white water, and after multiple dilutions, it is transported to the forming net through a pipeline to form a wet paper web, and then dried to form the final product.

[0003] The above method requires a huge amount of water, and the wastewater has a serious impact on the environment. In order to achieve the purpose of environmental protection and water conservation, the production line usually adopts a closed white water cycle to increase the reuse rate of white water and reduce the amount of clean water used for papermaking. However, as the number of times white water is reused increases, solid wastes such as fine fibers and cotton residues (referred to as solid waste) gradually accumulate in the white water circulation system, which will affect the quality of the final product.

[0004] Therefore, there is an urgent need to design a wet solid waste treatment device to remove solid waste from white water to improve the quality of the final product. Utility Model Content

[0044] like Figure 1-4 As shown, an embodiment of the utility model provides a wet solid waste treatment device, which includes a filtering unit 1, an extrusion unit 2 and a recovery unit 3, wherein:

[0045] The filtering unit 1 is used to filter the slurry containing solid waste to obtain first white water and first solid waste;

[0046] The extrusion unit 2 is connected to the filtering unit 1 and is used to extrude the first solid waste to squeeze out the remaining white water in the first solid waste to obtain the second white water and the second solid waste;

[0047] The recovery unit 3 is connected to the filtering unit 1 and the extruding unit 2 respectively, and is used for recovering the first white water and the second white water.

[0048] In this embodiment, by setting up the filtering unit 1, the solid waste such as fine fiber cotton residue in the bottom slurry can be filtered, and the water content of the solid waste can be further reduced by the squeezing unit 2, so that the solid waste content in the bottom slurry can be effectively removed, and the first white water obtained after filtering and the second white water obtained after squeezing can be recycled by the recycling unit 3 to increase the number of cycles of the white water. Therefore, the above technical solution can not only reduce the cost of solid waste treatment, but also reduce the waste of water resources, reduce production costs, and improve the quality of the final product.

[0049] In some embodiments, the types of solid waste include glass fiber waste residues generated during the production of glass fiber products, which are used in the field of wet papermaking, including AGM separators, air filter paper, coated paper, primary lithium battery separators, etc.

[0050] In one embodiment of the utility model, the device further comprises a housing 4, and the filtering unit 1, the extrusion unit 2 and the recovery unit 3 are all arranged on the housing 4. With such an arrangement, the complete separation of white water and solid waste can be achieved at one time on one device, thereby improving the quality of the final product.

[0051] In one embodiment of the present invention, the filter unit 1 comprises a first filter screen 11 obliquely arranged on the housing 4, and the recovery unit 3 is arranged below the first filter screen 11. Such an arrangement can facilitate the recovery of the first white water.

[0052] In one embodiment of the present invention, the filter unit 1 further comprises a support roller 12, the support roller 12 is fixed on the housing 4, and the first filter screen 11 is hung on the support roller 12. Such a configuration can facilitate the loading and unloading of the first filter screen 11.

[0053] In some embodiments, the shell 4 is made of stainless steel or plastic, preferably stainless steel, to prevent the shell 4 from being corroded by the slurry.

[0054] In one embodiment of the utility model, the filter unit 1 also includes a bracket 13 and a polarization motor 14, one end of the bracket 13 is fixed to the shell 4, and the other end is fixed to the first filter screen 11, the bracket 13 and the support roller 12 form two fulcrums of the first filter screen 11, and the polarization motor 14 is fixed on the bracket 13.

[0055] In this embodiment, generally speaking, the filter unit 1 can filter about 50% to 80% of the white water (i.e., obtain 50% to 80% of the first white water), while solid waste such as fine fiber cotton residue will remain on the first filter net 11. When subjected to gravity and the vibration force generated by the polarization motor 14, the first solid waste will fall smoothly into the extrusion unit 2.

[0056] In some embodiments, the moisture content of the first solid waste is generally about 5-15%.

[0057] In one embodiment of the present invention, the bracket 13 is welded to the first filter screen 11 , and the polarization motor 14 is fixed to the bracket 13 by bolts.

[0060] The screw 21 is used to convey the first solid waste, and the pressing assembly 23 is used to cooperate with the screw 21 to squeeze the first solid waste at the second filter screen 22 to squeeze out the second white water;

[0061] When the second solid waste reaches a certain amount at the second filter screen 22 , the pressing assembly 23 is pushed open to allow the second solid waste to be discharged from the housing 4 .

[0062] In this embodiment, in order to further reduce the moisture content in the first solid waste, a screw 21, a second filter screen 22 and a pressing assembly 23 are provided, so that the second white water can be pressed out conveniently and the discharge of the second solid waste can be ensured.

[0063] In one embodiment of the utility model, the clamping assembly 23 includes a fixed plate 231, a spring 232 and a movable plate 233 connected in sequence. The movable plate 233 is used to cooperate with the screw 21 to squeeze the first solid waste at the second filter screen 22, and when the second solid waste reaches a certain amount at the second filter screen 22, the movable plate 233 is pushed open to allow the second solid waste to be discharged from the shell 4.

[0064] In this embodiment, by providing a fixed plate 231, a spring 232 and a movable plate 233 connected in sequence, it is possible to conveniently press out the second white water and ensure the discharge of the second solid waste.
