Abstract
The invention relates to a TPA supply pipeline control system of a slurry blending tank. The system comprises a slurry blending tank (1) which is connected with a TPA supply pipeline (2). The TPA supply pipeline (2) is equipped with a TPA supply valve (2.1). The system is characterized in that a liquid level sensor (1.3) is arranged inside the slurry blending tank (1); a control circuit (3) is disposed between the liquid level sensor (1.3) and the TPA supply valve (2.1); and a liquid level controller (3.1), a flow controller (5.2) and a rotary feed controller (3.3) are arranged from front to back in the control circuit (3). The TPA 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 TPA 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 TPA 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 TPA feeding pipeline control rate precision of slurry mix tank.Therefore seek a kind of feeding speed control accuracy higher, the TPA 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 TPA feeding pipeline control system of artificial slurry mix tank.
The object of the present invention is achieved like this:
A kind of TPA feeding pipeline control system of slurry mix tank, comprise slurry mix tank, described slurry mix tank is connected with TPA feeding pipeline, described TPA feeding pipeline is provided with TPA inlet valve, it is characterized in that being provided with liquid level sensor in described slurry mix tank, be provided with control circuit between described liquid level sensor and TPA inlet valve, described control circuit be provided with from front to back fluid level controller, flow controller and rotate feed control.
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 TPA feeding pipeline control system of this slurry mix tank has Liquid level precision, saves artificial advantage.
