Description
Technical Field
The invention relates to molten material transfer equipment, in particular to a melt liquid level control device.
Background
In the chemical fiber spinning production process, the raw material moisture is generally required to be controlled within two thousandth, otherwise, defects such as yarn breakage and the like are easily caused in the spinning process, and the poor control of the moisture in the quality product rate is seriously influenced, and the production can not be caused seriously. At present, all factories generally adopt drying raw materials and then are used for producing the products, the drying time is generally more than 8 hours, and the energy-saving moisture can not be controlled to the best. However, this method is energy-intensive and inefficient. If the drying operation is directly carried out in the processing process, a transfer heating charging barrel needs to be adopted, an extruding machine in the prior art generally adopts a constant speed for extruding, and in actual operation, the situation that materials in the charging barrel are always kept at a certain height is difficult to ensure, short materials sometimes overflow to cause waste or abnormal production is sometimes caused, and the available high-temperature liquid level control device is lacked in the prior art because the melt temperature is very high.
Disclosure of Invention
Aiming at the defects and shortcomings of the prior art, the invention aims to provide a melt liquid level control device which is simple in structure and can control the liquid level of a transfer cylinder to be level and constant with the speed of an extrusion device.
In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a fuse-element liquid level control device, includes little DC motor, feed cylinder and electric box, little DC motor's below is provided with the stirring leaf, the stirring leaf is located the feed cylinder, be provided with adjusting resistance and converter control signal joint in the electric box, adjusting resistance is connected with little DC motor series connection electricity, converter control signal joint, the electric box is located little DC motor's side.
Furthermore, a screw extruder is arranged above the charging barrel, an extruding motor is arranged in the screw extruder, and the extruding motor is electrically connected with the frequency converter control signal connector.
Further, a porous screen is arranged at the outlet of the screw extruder.
Further, the electric box is fixedly connected with the screw extruder.
Further, the electric box is fixedly connected with the charging barrel.
The invention has the beneficial effects that:
the invention mixes the melt in the charging barrel by arranging a small DC motor in the charging barrel and arranging a mixing blade at the lower end, because the resistance of the stirring blade can be changed continuously along with the melt liquid level change in the charging barrel during the stirring process, the internal resistance of the small direct current motor can be changed, thereby causing the voltage at two ends of the regulating resistor connected in series with the small direct current motor to be changed, because the control frequency converter for controlling the extruding motor of the screw extruder is connected with the adjusting resistor in parallel, the voltage is the same as the voltage at the two ends of the adjusting resistor, the voltage provided by the frequency converter to the extruding motor is changed along with the voltage, thereby being capable of changing the rotating speed of the extruding motor, so that the rotating speed of the screw extruder can be adjusted to be matched with the liquid level in the charging barrel, the liquid level is low promptly, and the rotational speed is big, and the liquid level is high, and the rotational speed is little to the liquid level in the control feed cylinder that can be fine is invariable, carries out the transfer.
