Description

Technical Field

[0001] The utility model relates to a liquid conveying device, in particular to a portable conveying device for barreled liquids at normal temperature and high temperature. Background Art

[0002] In the process of chemical production, in most cases, there will be some chemical raw materials that are solid at normal temperature or chemical raw materials that are liquid at normal temperature and not suitable for direct human contact. And in most cases, they are canned or barreled. To transfer such raw materials, it is necessary to heat such chemical raw materials to a certain temperature (at least above the melting point), and then transfer the materials to other storage tanks and other equipment for use. High-temperature liquid transportation can be divided into fixed and non-fixed forms according to whether it is in a fixed form. Among them, fixed transportation generally uses melt pumps with heat preservation or heating devices to realize the transportation of chemical raw materials that are solid at normal temperature and melted at high temperature. This is generally applicable to scenarios that require long-term and fixed use, are not easily moved, and the transfer volume reaches a certain amount. The advantage is that it can be put into use stably for a long time once implemented; the other is non-fixed high-temperature liquid transportation, which is generally applicable to the transportation of chemical raw materials with small transfer volume and variable positions. This type of transfer method is relatively simple and crude, and is generally realized by pouring, mechanical hand pumps or temporarily using fixed mechanical equipment.

[0003] The fixed high-temperature liquid transportation and transfer are currently relatively unified and have relatively high efficiency. However, for non-fixed high-temperature liquid transfer, although there are various forms, each transfer method has obvious defects. The most conventional pouring transfer will face high-temperature burns, falling and smashing injuries, etc.; for mechanical hand pumps, it is difficult to completely clean the material residues after use, and the probability of jamming during reuse is very high, and the efficiency is low, and the labor cost and equipment cost are high; temporarily using a fixed high-temperature liquid conveying device requires considering the usage scenario, space, and installation conditions. Generally, the installation cost is high, the cleaning process is relatively complex, and there is a high probability of permanent damage to the conveying equipment. Summary of the Utility Model

A pressure gauge, a pressure relief valve, and a pressure reducing valve group are connected to the pressurized air pipe outside the liquid conveying pipe.
