Description

Technical Field

[0001] The utility model relates to a transfer bag with a drainage function, in particular to a polyethylene wax transfer drainage bag. Background Art

[0002] Polyethylene wax (PE wax), a byproduct of polyethylene production, is widely used as an additive for polyolefin processing, playing a prominent role in increasing the gloss of products. And because of its strong internal lubrication, it is often used as a mold release agent for polymer materials. Polyethylene wax contains a high proportion of free water when it is discharged from the reactor, and it is necessary to drain this water as much as possible before storage. In order to improve the efficiency of production and transportation, polyethylene wax is usually transported from the production line to the storage and transportation process with the help of drainage transfer bags to achieve drainage during bagging and transportation, and to remove the water phase contained in the polyethylene wax as much as possible before it reaches the storage workshop.

[0003] The Chinese utility model with the authorization announcement number CN216334183U discloses "a drainage ton bag and an engineering mud and water separation and transfer device", in which the drainage ton bag uses geotextile as the outer surface to dehydrate the engineering mud. The engineering mud is loaded into the drainage ton bag, and the drainage ton bag is hung up by a hanging ring for static dehydration. Although the geotextile has the function of water seepage, it has the defect of low drainage rate when used as the outer surface of the polyethylene wax transfer drainage bag. In particular, since polyethylene wax, as a polymer material, has the ability to self-deform, it has a tendency to close the fine mesh of the geotextile after bagging. The use of this drainage and transfer method will result in too low drainage efficiency, which is difficult to meet the production and storage and transportation turnover requirements. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a polyethylene wax transport drain bag with

[0005] It has mesh suitable for rapid drainage of polyethylene wax and has sufficient packaging strength.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A polyethylene wax transport drain bag comprises a rectangular bag body consisting of a rectangular bottom, four rectangular sides and a top, wherein the rectangular bottom, four rectangular sides and a top are respectively woven from warp strips and weft strips, and the four rectangular sides respectively have a plurality of strip-shaped drain areas of the same height as the bag body; the areas outside the strip-shaped drain areas in the four rectangular sides and the bottom area are sealing areas; and blank areas are provided between adjacent warp strips in the strip-shaped drain areas.

[0008] Preferably, the bag body is also connected to four lifting straps; the upper ends of the lifting straps are lifting rings formed by bending, and the lower ends are located at the lower sides of the rectangular sides.

[0009] Preferably, the top surface is provided with an inlet and outlet port and the inlet and outlet port is connected to an inlet and outlet barrel communicating with the inner cavity of the bag body; the inlet and outlet barrel is made of a rigid material to ensure that it remains in an open state when the bag body is lifted.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] First, the four rectangular sides of the utility model each have a plurality of strip-shaped drainage areas of the same height as the bag body, and there are blank areas between adjacent strips in the strip-shaped drainage areas. After the transport drainage bag is filled with water-containing polyethylene wax, the water is discharged from the blank areas, and the polyethylene wax is sealed in the bag body by the sealing area.

[0012] The new type has a mesh that is more suitable for the rapid drainage of polyethylene wax, with a fast drainage speed, which can better meet the production and storage and transportation turnover requirements.

[0013] Second, the areas outside the strip-shaped drainage areas on the four rectangular sides of the utility model and the bottom area are densely woven sealing areas, which are not provided with drainage holes, and the lower end of the lifting belt is located at the lower side of the rectangular side. This design can better ensure the overall strength of the drainage bag and avoid damage to the bag body and material leakage due to excessive load. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is described in detail below in conjunction with the embodiments and drawings.

[0019] like Figure 1 and Figure 2The embodiment of the polyethylene wax transfer drain bag of the utility model comprises a rectangular parallelepiped bag body consisting of a rectangular bottom surface, four rectangular side surfaces and a top surface. The top surface is provided with an inlet and outlet port and the inlet and outlet port is connected to an inlet and outlet barrel 2 which is in communication with the inner cavity of the bag body. The root of the inlet and outlet barrel 2 is connected to the top surface by sewing, and the suspended end of the inlet and outlet barrel 2 is open. The inlet and outlet barrel 2 has a certain rigidity to ensure that the suspended end opening remains in an open state when the bag body is hoisted.

[0020] The rectangular bottom surface, four rectangular sides and one top surface are respectively woven from a plurality of warp strips 4 and a plurality of weft strips 5. The four rectangular sides respectively have a plurality of strip-shaped drainage areas 3 of the same height as the bag body, and the areas outside the strip-shaped drainage areas 3 in the four rectangular sides and the bottom surface area are sealing areas. Figure 3 , the blank area 3-1 is between adjacent warp strips 5 in the strip-shaped drainage area 3 (blank area generated by omitting the warp strips during weaving). After the transport drain bag is filled with water-carrying polyethylene wax, the water is discharged from the blank area 3-1, and the polyethylene wax is sealed in the bag body by the sealing area.
