Viscous-proof chlorinated paraffin liquid storage tank for rubber compound mixing

Abstract

The invention discloses a viscous-proof chlorinated paraffin liquid storage tank for rubber compound mixing. The liquid storage tank comprises a liquid storage tank body and a taking opening; the lower part of the liquid storage tank body is coated with a tank body heat insulating sleeve; electric heating pipes are clamped between the tank body heat insulating sleeve and the liquid storage tank body; a temperature sensor is packaged inside the tank body heat insulating sleeve; a microcontroller is inlaid in the surface of the liquid storage tank body and is in series connection with a power supply wire of the electric heating pipes; and an automatic discharging device is mounted at the taking opening and is in signal connection with the microcontroller. The tank body heat insulating sleeveand the electric heating pipes are separately arranged at part of the outer side of the liquid storage tank body and only heat chlorinated paraffin close to the taking opening, so that the conditionthat a raw material inside cannot flow out successfully due to increase of the viscosity during discharging in winter is prevented, and the electric energy can be saved due to the fact that the electric heating pipe is arranged partially; and through cooperation of the automatic discharging device and the microcontroller, quantitative and automatic discharging of the chlorinated paraffin can be realized, and manual control is not required, so that the liquid storage tank is easy to use, and the taking error is small.

Description

technical field [0001] The invention relates to the technical field of chlorinated paraffin storage equipment, in particular to an anti-sticking chlorinated paraffin liquid storage tank for mixing rubber ingredients. Background technique [0002] Chlorinated paraffin is a chlorinated derivative of paraffin. It has the advantages of low volatility, flame retardancy, good electrical insulation, and low price. It can be used as a flame retardant and an auxiliary plasticizer for polyvinyl chloride. It is used in plastics, rubber, It is used as a plasticizer in industrial fields such as fibers, and as an additive in industrial fields such as polyurethane waterproof coatings, polyurethane plastic runways, and lubricating oil. The chlorinated paraffin used as a plasticizer in rubber production is a light yellow viscous liquid. This kind of chlorinated paraffin has a low freezing point and will completely solidify when the temperature is lower than -30°C. When chlorinated paraffins...

AI Technical Summary

Problems solved by technology

Due to the simple structure of the storage tank for storing chlorinated paraffin, the insulation effect is poor. When used in winter, although the general temperature does not reach its freezing point temperature, the low temperature will affect the viscosity of the chlorinated paraffin. When the temperature is below 0°C , the viscosity of chlorinated paraffin obviously increases, and its flow velocity decreases obviously, seriously affecting the efficiency of reclaiming

In addition, when retrieving materials, the current method of retrieving materials is that the staff perform manual retrieving operations by operating the control valve, and weigh with the help of the electronic scale under the receiving barrel, which has large errors and slow speed.
