Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle storage, and in particular relates to a moisture-proof storage device for plastic particle processing. Background Art

[0002] The production of plastic particles is a production process in which polymer resins are mixed with various additives and auxiliaries through metering, mixing, plasticizing and pelletizing to form granular plastics. Plastic particles are only semi-finished products of the plastic molding industry and are raw materials for hollow blow molding, foaming and other molding processing industries. The produced plastic particles need to be stored and stored using moisture-proof equipment.

[0003] Desiccant refers to a substance that can remove moisture from moist substances. It is usually divided into two categories: chemical desiccants, such as calcium sulfate and calcium chloride, which dry by combining with water to form hydrates; and physical desiccants, such as silica gel and activated alumina, which dry by physically adsorbing water.

[0004] In the Chinese patent with publication number CN 218617961 U, the internal placement frame supports the clamping ring and the storage box to prevent the storage box from directly contacting the ground, causing the plastic particles in the storage box to get damp and affect subsequent processing. The dehumidifier on the discharge plate dehumidifies the plastic particles in the storage box, thereby preventing the plastic particles from getting damp, so that the storage box has a better moisture-proof storage effect on the plastic particles.

[0005] However, the dehumidifier in the above device is placed on the discharge plate on one side of the outer wall of the storage box, where the space in contact with the plastic particles in the storage box is limited, the plastic particles accumulate in the storage box, and gas interaction is inconvenient, so the dehumidification effect is poor.

[0009] Several discharge ports are provided on the outer wall of the transfer box;

[0010] A top cover is installed on the transfer box, and a feed pipe is inserted into the top cover.

[0011] Preferably, four drying bags are provided, and the four drying bags are distributed in a circular array around the center line of the storage tank. The drying bags are woven bags with mesh holes of different sizes, and the mesh holes are used for the circulation of gas.

[0025] 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.

[0026] Reference Figure 1-Figure 4 A moisture-proof storage device for processing plastic particles, comprising a storage tank 1 and a drying bag 2, wherein the storage tank 1 is used to store processed plastic particles, and the drying bag 2 is inserted into the storage tank 1 to store a desiccant;

[0027] In a further embodiment, the drying bag 2 adopts a woven bag. The plastic woven bag is mainly composed of polypropylene bags and polyethylene bags. It is divided into bottom-sewn bags and side-sewn bottom bags according to the sewing method. It is currently widely used as a packaging material for fertilizers, chemical products and other items. Its main production process is to use plastic raw materials to extrude films, cut, and unidirectionally stretch them into flat wires, and then weave them through warp and weft to obtain products, which are generally called woven bags. The woven bags have large and small mesh holes, which are used for gas exchange. The desiccant filled in the drying bag 2 is used to absorb moisture in the plastic particles in the storage tank 1. In order to prop up the drying bag 2 and prevent it from collapsing due to the squeezing of the plastic particles, a skeleton 3 is installed in the drying bag 2. The skeleton 3 includes a plurality of circularly distributed vertical rods 301, which are arranged in a plurality of vertical rods 301. A fixing ring 302 is fixedly installed between the vertical rods 301. The gaps between the vertical rods 301 are filled with a large number of plastic particles. Because these plastic particles are filled in the gaps, they will remain inside the drying bag 2 when the lifting and lowering mechanism 4 drives the plastic particles to move up and down. Therefore, a vibration mechanism 303 for driving the shaking is installed on the frame 3. The vibration mechanism 303 drives the frame 3 to shake, and vibrates the desiccant stored in the gaps between the vertical rods 301 to the middle position of the drying bag 2. When the lifting and lowering mechanism 4 pushes the desiccant out of the drying bag 2, the desiccant is pushed out more thoroughly. When the desiccant enters the drying bag 2, the shaking of the frame 3 can make the desiccant enter the gaps between the vertical rods 301 better.

[0028] In a further embodiment, a lifting and lowering mechanism 4 for transporting the desiccant is installed in the drying bag 2, and the lifting and lowering mechanism 4 includes spirally distributed conveying blades and a conveying motor for driving the conveying blades to rotate; the lifting and lowering mechanism 4 is specifically used to convey the desiccant after absorbing moisture into the transfer box 5, or to convey new desiccant from the transfer box 5 into the drying bag 2;

[0029] The desiccant that has absorbed moisture needs to be pushed out of the transfer box 5, so a slope 501 is set at the bottom of the transfer box 5, and a plurality of discharge ports 6 are set at the outer wall of the transfer box 5. The height of the slope 501 near the discharge port 6 is lower than that of the other side. Therefore, after the desiccant that has absorbed moisture enters the transfer box 5, it will move to the edge of the discharge port 6 under the action of its own gravity and gather at the bottom of the transfer box 5. Figure 4 At the leftmost position shown;

[0030] In a further embodiment, in order to facilitate the loading of the desiccant, a top cover 7 is installed on the transfer box 5, and a feed pipe 8 is inserted in the top cover 7. The feed pipe 8 is used for the entry of the desiccant. Specifically, the top cover 7 is rotatably connected to the transfer box 5. During the rotation of the top cover 7, it is aligned with each drying bag 2, so as to cooperate with the lifting and lowering mechanism 4 inside the drying bag 2 to feed the desiccant into the drying bag 2. At the same time, in order to allow the desiccant that absorbs moisture to be discharged from the discharge port 6, a push plate 9 is fixedly installed on the top cover 7, and an inclined structure cooperating with the slope 501 is provided on the push plate 9.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
