Description

TECHNICAL FIELD

[0001] The utility model relates to quartz sand purification technical field, concretely is a kind of quartz sand chlorination purification automatic unloading car for feeding. BACKGROUND

[0002] High-purity quartz sand generally refers to SiO2 Content higher than 99.9% quartz powder, mainly applied in IC integrated circuit and quartz glass industry, and its high product is more widely applied in large-scale and super large scale integrated circuit, optical fiber, laser, aerospace, military and other fields. The purification of quartz sand is mainly to remove a small amount or trace impurities, to obtain high-purity quartz sand;

[0003] Quartz sand chlorination purification technology refers to the process of chlorination roasting under certain conditions, which makes some components in mineral raw materials into gaseous or condensed chlorides under the action of chlorinating agent, so as to separate or enrich the components. Chlorination roasting is also known as chlorination degassing. Quartz sand chlorination roasting is one of the technologies in high-purity quartz sand purification process, mainly for the treatment of lattice impurities in quartz sand, to obtain high-purity quartz sand with SiO2 content greater than 99.9%;

[0004] In the process of quartz sand chlorination purification, quartz tube roasting furnace is needed to treat quartz sand. Quartz sand is put into one end of the quartz tube, chlorine gas is injected from the other end of the quartz tube, and then the quartz tube drives the quartz sand in the tube to turn over in the process of rotation, so as to contact with the reverse chlorine gas, and realize the purification of quartz sand in high temperature environment.

[0005] Since the quartz sand raw material is stored in the bucket, the feeding work of quartz sand is generally carried out by the bucket holder to transport and feed the material in the workshop. When transporting and feeding, the bucket holder can lift the bucket to a certain height, and then push it to the specified position by the operator, and then pour out the material in the bucket to the feeding point through the pouring device. For example, the patent document with publication number "CN 219603181 U" disclosed a workshop bucket conveying device, which comprises a walking base, an operating longitudinal beam, a longitudinal slide rail, a lifting frame, a lifting drive device, a bucket edge clamping device, a bucket body embracing device, a bucket bottom lifting device and a turnover driving device. Although the bucket conveying device saves time and effort when pouring material into the weighing device, the bucket fixing effect is good, the bucket is not easy to fall off when turning over and pouring, and the production efficiency is improved. However, when pushing, the whole device plus the bucket and the material have a certain weight, and the universal wheels are set at the bottom, which makes it difficult to control the direction of the whole device. When turning, the operator needs to apply pulling force left and right, so that it is not convenient to use, and its controllability and flexibility are general. UTILITY MODEL CONTENT
