Description

Technical Field

[0001] The utility model relates to a filtering device, in particular to a pulp filtering device for a paper tray, and belongs to the technical field of paper tray production. Background Art

[0002] Molded pulp tray, also known as pulp molding, is made of carton scraps (Kraft Pulp), newsprint, white pure wood pulp (Virgin Pulp) and other raw materials. After pulping and mixing into a certain proportion of pulp concentration, it is formed on a CNC tooling customized according to product design, vacuum adsorption molding (Forming process), and finally dried to form environmentally friendly paper products of different types and uses. When producing paper trays, waste paper or other raw materials need to be made into pulp, and then these pulps are remade into paper trays. Since these pulps are made of waste paper and other materials, they contain some impurities or larger fibers. Therefore, the impurities in the pulp need to be removed before papermaking.

[0003] For example, an environmentally friendly pulp impurity removal and filtering device disclosed in patent announcement number CN220276425U includes: a base, a box, a stirring assembly, a feeding assembly and a storage assembly, wherein the box is arranged on the base, the stirring assembly is arranged in the box, the feeding assembly is arranged in the box and is located at the lower side of the stirring assembly, and the storage assembly is arranged on the base. The utility model intercepts and filters the impurities and coarser particles in the pulp by using a filter screen 1, stirs the pulp by using a plurality of stirring rods, thereby improving the filtration efficiency of the pulp, filtering the excess water in the pulp by using a filter screen 2, and conveying the pulp by using the rotation of the spiral impeller, thereby avoiding clogging of the feeding pipe and keeping the discharge smooth. The separated pulp is compressed under the action of the cylinder pushing the pressure plate, thereby reducing the space occupied by the separated pulp, realizing the continuous filtration and impurity removal and solid-liquid separation of the pulp, and improving the work efficiency. However, during use, because the pulp has a certain degree of adhesion, the pulp remaining on the surface of the filter screen needs to be cleaned regularly, and the above structure is not convenient for disassembling the filter screen.
