The pipeline control system of the pulp feed tank has the advantages of higher discharge speed and liquid level control precision, and labor saving.
Description
Technical field
The present invention relates to a kind of slurry feed tank, particularly relate to a kind of slurry feed tank pipe control system, belong to field of chemical equipment.
Background technology
In production PET Process, need to use slurry feed tank, slurry feed tank is except feeding is to except slurry mix tank and esterification heat exchanger, self also has feed back, traditional more difficult control of slurry feed tank pipeline flow, liquid level in slurry feed tank is more difficult control also, needs to regulate manually the speed of feed in the speed of feed back in slurry feed tank return pipeline, supply lines, the speed of charging in feed pipe.For maximization production line, if need workman's manual operation, waste a large amount of artificial, and the speed of slurry feed tank discharging, and the more difficult assurance of liquid level.Therefore seek a kind of speed of discharging, Liquid level precision is higher, save artificial slurry feed tank pipe control system particularly important.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of speed of discharging, Liquid level precision higher, save artificial slurry feed tank pipe control system.
The object of the present invention is achieved like this:
A kind of slurry feed tank pipe control system, comprise slurry feed tank, it is characterized in that the discharging opening of described slurry feed tank is connected with discharge pipe, the rear end of described discharge pipe is connected with feed back pipeline and feeding pipeline, the rear end of described feed back pipeline connects the feedback outlet of slurry feed tank, described feed back pipeline is provided with first flow transmitter and material returning valve from front to back, the first control circuit is provided with between described first flow transmitter and material returning valve, described first control circuit is provided with first flow controller, described feeding pipeline is provided with second transmitter and inlet valve from front to back, the second control circuit is provided with between described second transmitter and inlet valve, described second control circuit is provided with second amount controller, the charging aperture of described slurry feed tank is connected with feed pipe, described feed pipe is provided with inlet valve, liquid level sensor is provided with in described slurry feed tank, the 3rd control circuit is provided with between described liquid level sensor and inlet valve, described 3rd control circuit is provided with from front to back fluid level controller and the 3rd flow controller.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention controls the aperture of material returning valve, inlet valve and inlet valve by the signal of control circuit, thus controls the discharging speed of slurry feed tank and the liquid level of slurry feed tank.This slurry feed tank pipe control system has the speed of discharging, Liquid level precision is higher, saves artificial advantage.
