Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of welding flux raw material circulation feeding devices, and specifically is a kind of welding flux raw material circulation feeding device. BACKGROUND

[0002] In modern welding industry, as a kind of key auxiliary material, the quality and production efficiency of welding flux directly affect the stability of welding process and the quality of final welding product. With the continuous development of manufacturing industry and the increasing demand for welding quality, the production scale of welding flux is also continuously expanding, which makes the efficient utilization and accurate feeding of welding flux raw materials become an important problem to be solved in the industry.

[0003] In the traditional welding flux production process, the raw material feeding device usually adopts simple storage container and single feeding mode, lacks effective pretreatment and recycling mechanism of raw materials, which leads to a series of serious problems: due to the easy caking of raw materials during storage, and the possible differences in particle size and composition of different batches of raw materials, the traditional feeding device cannot fully stir and mix them, which affects the uniformity of raw materials entering the production link, and further affects the accuracy of welding flux formula and product quality stability. In the welding process, due to unstable welding flux quality, defects such as weld porosity, cracks and slag inclusion may occur, which reduces the strength and reliability of welded joints, seriously affects the quality of welded products, increases the scrap rate and rework cost, and brings huge economic losses to enterprises.

[0004] In the production process, part of the raw materials that are not fully reacted or left over due to various reasons are often treated as waste, causing serious waste of resources. This not only increases the raw material procurement cost of enterprises, but also causes unnecessary burden to the environment, which is not in line with the concept of sustainable development of modern industry. Moreover, the traditional feeding device lacks precise measurement and control means in the feeding process, and cannot accurately adjust the amount of raw materials according to production needs, which further aggravates the waste of raw materials, and also makes it difficult to meet the requirements of some high-precision welding processes for accurate control of welding flux composition.

[0005] In summary, in order to meet the urgent needs of modern welding industry for high-quality and high-efficiency production of welding flux, as well as resource saving and environmental protection, an innovative welding flux raw material circulation feeding device is urgently needed to solve the many problems existing in the above-mentioned traditional feeding mode, realize efficient mixing, recycling and automatic control of welding flux raw materials, and thus improve the quality and efficiency of welding flux production.
