Description

TECHNICAL FIELD

[0001] The utility model relates to flowmeter technical field, concretely is quartz sand chlorination purification furnace is with chlorine flowmeter. BACKGROUND

[0002] The high-purity quartz sand purification process mainly includes mechanical crushing, magnetic separation, flotation, calcination, high-temperature chlorination purification and multiple operation steps, wherein, the high-temperature chlorination purification step of quartz sand is the last purification step of preparing high-purity quartz sand, is the structure reconfiguration caused by the phase change (alpha phase, beta phase and gamma phase) of quartz crystal at different high temperatures, so that the volume expands and tears, a large number of microcracks are generated inside, low-boiling-point gaseous potassium chloride, sodium chloride and lithium chloride are generated by the reaction of chlorine gas and metal impurities in quartz sand at high temperature, especially alkali metal impurities, and escape, thereby reducing the content of metal impurities in quartz sand raw materials, and high-purity quartz sand can be obtained after high-temperature chlorination purification.

[0003] In order to facilitate monitoring and controlling the amount of chlorine gas, a rotor flowmeter is generally installed in the chlorine gas inlet pipeline. The rotor flowmeter is a commonly used flowmeter, mainly including a glass rotor flowmeter and a metal rotor flowmeter. The glass rotor flowmeter includes a conical transparent tube (mostly made of glass) and a rotor arranged therein. The rotor is movably arranged in the conical transparent tube. During operation, the position of the rotor in the conical tube corresponds to the flow rate. In addition, a scale is provided on the conical transparent tube.

[0004] For example, the patent document with the publication number "CN 219038104 U" disclosed a glass rotor flowmeter with detachable dehumidification detection function, which includes a shell, a measurement assembly, a first base and a dehumidification detection layer. Although the flowmeter can detect and dehumidify the external gas, reduce the moisture of the gas flowing into the measurement assembly, improve the measurement accuracy, and further prolong the service life of the glass rotor flowmeter, the inlet and outlet holes of the flowmeter still need to be connected with the external pipeline by means of external clamps when connected with the external pipeline. The external pipeline is tightly fixed on the inlet and outlet holes by the clamps. However, the installation method of the clamps not only needs to use external tools, but also has the disadvantage of uncertainty. The operator needs to determine the fastening force and sealing effect according to the specific situation. If there is a mistake during installation, it is easy to cause gas leakage, which affects the normal operation of gas delivery. Therefore, the stability and reliability of the connection are not certain. UTILITY MODEL CONTENTS
