However, if they are needed to be used to crush chemical raw materials, there will be great risks, that is, the crushing of chemical raw materials is best done in a vacuum or inert gas protected environment, and dedicated chemical raw material crushers are expensive and have a small scope of application.
[0003] Therefore, it is very necessary to provide a low-cost, easy-to-use, and easy-to-popularize sealed circulation device for small pulverizers. Summary of the invention
[0004] The purpose of the utility model is to solve the above problems existing in the current technology and to propose a sealing circulation device for a small pulverizer, which has the advantages of low cost, easy use and easy popularization.
[0005] The technical solution to achieve the purpose of this utility model is:
[0006] A sealing circulation device for a small pulverizer comprises a plastic material feed sealing body, a plastic material discharge sealing body and a gas circulation pipeline, wherein the plastic material feed sealing body is provided with a feed opening and a vent, and the plastic material discharge sealing body is provided with a discharge opening and a vent, the plastic material feed sealing body and the plastic material discharge sealing body respectively seal the pulverizer and then the gas circulation pipeline forms a sealed circulation environment which is oxygen-free or filled with protective gas, the gas circulation pipeline is in the form of a three-way pipeline, the upper and lower ends of which are respectively connected to a vacuum pump or a protective gas cylinder and the plastic material discharge sealing body, and the middle pipe opening is connected to the plastic material feed sealing body.
[0007] In some embodiments, the plastic material inlet sealing body and the plastic material outlet sealing body are both made of soft plastic material, and can play the role of sealing and material feeding and discharging at the same time.
[0008] In some embodiments, the gas circulation pipeline can be divided into use in the cases of vacuuming and filling with protective gas; in the case of vacuuming, the gas circulation pipeline needs to be connected to a vacuum machine, and after the vacuuming is completed, the vents on the plastic material feed sealing body and the plastic material discharge body are closed with a thin wire or a cable tie; in the case of filling with protective gas, the gas circulation pipeline needs to be connected to a protective gas cylinder.
[0009] Compared with the prior art, the utility model has a simple and reasonable structure, is easy to implement, has the advantages of low cost, convenient use, easy popularization, etc., and has practical and promotion value. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 The utility model is a structural schematic diagram of a sealing circulation device for a small pulverizer.
[0011] In the figure: 1. Plastic material feed sealing body; 2. Plastic material discharge sealing body; 3. Gas circulation pipeline. DETAILED DESCRIPTION
[0012] The following description is made in conjunction with specific embodiments, which are merely exemplary and do not constitute any limitation to the scope of the present invention.
[0013] like Figure 1 As shown, a sealing circulation device for a small pulverizer includes a plastic material feed sealing body, a plastic material discharge sealing body and a gas circulation pipeline, wherein the plastic material feed sealing body is provided with a feed opening and a vent, and the plastic material discharge sealing body is provided with a discharge opening and a vent, wherein the plastic material feed sealing body and the plastic material discharge sealing body respectively seal the pulverizer and then the gas circulation pipeline forms a sealed oxygen-free or protective gas-filled sealed circulation environment; the gas circulation pipeline is in the form of a three-way pipeline, wherein the upper and lower ends are respectively connected to a vacuum pump or a protective gas cylinder and the plastic material discharge sealing body, and the middle pipe opening is connected to the plastic material feed sealing body. The plastic material feed sealing body and the plastic material discharge sealing body are both made of soft plastic material, wherein the plastic material feed sealing body is fixed to the feed opening of the pulverizer by a thin iron wire or a cable tie and plays the role of feeding and sealing, and the plastic material discharge sealing body is fixed to the discharge opening of the pulverizer by a thin iron wire or a cable tie and plays the role of discharging and sealing. The gas circulation pipeline can be used in the conditions of vacuuming and filling with protective gas; in the condition of vacuuming, the gas circulation pipeline needs to be connected to the vacuum machine, and after the vacuuming is completed, the air vents on the plastic material feed sealing body and the air vents on the plastic material discharge body are closed with thin iron wire or cable ties; in the condition of filling with protective gas, the gas circulation pipeline needs to be connected to the protective gas cylinder so that the sealing circulation device and the crusher form a sealed environment.
[0014] The sealed circulation device of this small pulverizer is used for the crushing of sodium borohydride raw materials. First, the raw materials are put into the pulverizer, and then the feed port and the discharge port of the pulverizer are sealed with a plastic material feed sealing body and a plastic material discharge sealing body respectively. The gas circulation pipeline in the form of a three-way pipeline is connected to the vent of the plastic material feed sealing body and the vent of the plastic material discharge sealing body, and nitrogen is introduced through the gas circulation pipeline, and the sodium borohydride raw materials can be crushed safely. After multiple tests, it can be carried out safely and quickly and can be used repeatedly. It can also be easily remade after loss, which will not affect the normal operation of the original pulverizer and will not cause wear and tear on it.
[0015] The specific embodiments described in this article are merely examples of the spirit of the utility model, but the present application is not limited to the specific details in the above-mentioned embodiments. Within the technical spirit of the present application, the specific embodiments described can be modified or supplemented in many ways or replaced with similar materials, all of which fall within the scope of protection of the present application.
