Description

Technical Field

[0001] The utility model relates to the field of plastic particle storage devices, in particular to a storage device for storing plastic particles. Background Art

[0002] Plastic particles are the common name for plastic particles. They are the raw materials for storage, transportation and processing of plastics in the form of semi-finished products. Plastics are a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, etc. can be produced using petroleum as raw material. The molecules of these substances can react with each other under certain conditions to form compounds with large molecular weight, namely polymers.

[0003] In the production process of related enterprises, plastic particles are generally stored in storage devices. When the corresponding plastic particles are used, the storage device storing the plastic particles is connected to the corresponding equipment, and then the discharge valve at the bottom of the storage device is opened. The plastic particles can automatically fall into the equipment for subsequent processing.

[0004] Among them, the Chinese patent with patent number ZL202221695705.6 discloses: "A storage device for plastic particles, whose structure includes a storage tank body, a base, a discharge hopper, a control device, and a pneumatic feeding pipe. The lower end of the storage tank body is fixedly connected to the base, and a discharge hopper is provided at the bottom of the storage tank body. The storage tank is provided with a control device, and the pneumatic feeding pipe is connected to the upper end of the storage tank. The storage device for plastic particles improves the existing technology by providing an internal feeding pipe, an output port, a separation bin, a discharge pipe, a discharge pipe control valve and other structures. In actual use, there are still differences between different batches of plastics. The existing storage device cannot mix different batches of plastics. During use, the produced plastic particles are sequentially loaded into different separation bins. When output is required, the discharge pipes of all separation bins are opened to mix and output plastic particles from different batches, thereby avoiding the problem of possible differences between different batches of plastics and improving the product yield."

[0005] However, including the solutions described in the above-mentioned patents, there is a problem with the existing storage devices for storing plastic particles on the market, that is, the sealing of the existing storage devices is poor, and external air can enter the storage devices through the gaps on the storage devices. The storage of some plastic particles has high requirements for humidity, which makes it impossible to store these plastic particles in large quantities and for a long time in the storage devices. The plastic particles in the storage devices need to be consumed in a short time to prevent them from being affected by moisture and degeneration.
