Abstract
The invention relates to an EG supply pipeline control system of a slurry blending tank. The system comprises a slurry blending tank (1) which is connected with an EG supply pipeline (2). The system is characterized in that a flow transmitter (2.1) and an EG supply valve (2.2) are arranged from front to back on the EG supply pipeline (2); a control circuit (3) is disposed between the flow transmitter (2.1) and the EG supply valve (2.2); and the control circuit (3) is equipped with a flow controller (3.1). The EG supply pipeline control system of the slurry blending tank has advantages as follows: liquid level control precision is high; and manpower is saved.
Description
Technical field
The present invention relates to a kind of slurry mix tank, particularly relate to a kind of EG feeding pipeline control system of slurry mix tank, belong to field of chemical equipment.
Background technology
In production PET Process, need to feed TPA(terephthalic acid (TPA) to slurry mix tank) and EG(ethylene glycol), and the more difficult control of feeding speed of traditional EG feeding pipeline, need the aperture regulating slurry mix tank material inlet valve manually.For maximization production line, if need workman's manual operation, waste a large amount of artificial, and the more difficult assurance of EG feeding pipeline control rate precision of slurry mix tank.Therefore seek a kind of feeding speed control accuracy higher, the EG feeding pipeline control system of saving artificial slurry mix tank is particularly important.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of feeding speed control accuracy higher, save the EG feeding pipeline control system of artificial slurry mix tank.
The object of the present invention is achieved like this:
A kind of EG feeding pipeline control system of slurry mix tank, comprise slurry mix tank, described slurry mix tank is connected with EG feeding pipeline and TPA feeding pipeline, described EG feeding pipeline is provided with from front to back flow transmitter and EG inlet valve, be provided with control circuit between described flow transmitter and EG inlet valve, described control circuit be provided with first flow controller.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention controls the aperture of inlet valve by the signal of control circuit, thus controls the feeding speed to slurry mix tank, ensures that slurry mix tank liquid level is able to accurate control.It is higher that the EG feeding pipeline control system of this slurry mix tank has Liquid level precision, saves artificial advantage.
