Abstract
The utility model relates to a liquid level control system of a second drainage receiver. The system comprises the second drainage receiver (1). The system is characterized in that the material outlet of the second drainage receiver (1) is provided with a material outlet pipe (2). The material outlet pipe (2) is provided with an output pump (2.1). The back end of the material outlet pipe (2) is in parallel connection with a first drainage receiver material feeding pipe (3) and a second drainage receiver material receiving pipe (4). The first drainage receiver material feeding pipe (3) is provided with a material feeding valve (3.1). The second drainage receiver (1) is provided with a liquid level sensor (1.1). A control circuit (5) is disposed between the liquid level sensor (1.1) and the material feeding valve (3.1). The control circuit (5) is provided with a liquid level controller (5.1). The system is advantaged by being high in liquid level control precision and saving manpower.
Description
Technical field
The utility model relates to a kind of the second drainer, relates in particular to a kind of the second drainer tank level control system, belongs to the chemical plant field.
Background technology
In producing PET Process, need to carry out condensation to material with the second drainer, the more difficult control of liquid level in the second traditional drainer, need to regulate the speed of the second drainer to feed in the first drainer manually.For the maximization production line, if need workman's manual operation, waste a large amount of artificial, and the more difficult assurance of the second drainer liquid level control accuracy.Therefore seek a kind of liquid level control accuracy higher, save the second artificial drainer tank level control system particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of liquid level control accuracy higher, saves the second artificial drainer tank level control system.
The purpose of this utility model is achieved in that
A kind of the second drainer tank level control system, comprise the second drainer, the discharging opening that it is characterized in that described the second drainer is provided with discharge pipe, be provided with rear pump on described discharge pipe, the rear end of described discharge pipe is connected in parallel to the first drainer feeding pipeline and the second drainer feed back pipeline, be provided with inlet valve on described the first drainer feeding pipeline, be provided with liquid level sensor on described the second drainer, be provided with operation circuit between described liquid level sensor and inlet valve, on described operation circuit, be provided with fluid level controller.
Compared with prior art, the beneficial effects of the utility model are:
The utility model passes through the aperture of the signal controlling inlet valve of operation circuit, thereby controls to the feeding speed of the first drainer, guarantees that the second drainer liquid level is able to accurate control.It is higher that this second drainer tank level control system has the liquid level control accuracy, saves artificial advantage.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model the second drainer tank level control system.
Wherein:
The second drainer 1, liquid level sensor 1.1
The first drainer feeding pipeline 3, inlet valve 3.1
The second drainer feed back pipeline 4
Embodiment
Referring to Fig. 1, a kind of the second drainer tank level control system that the utility model relates to, comprise the second drainer 1, the discharging opening of described the second drainer 1 is provided with discharge pipe 2, be provided with rear pump 2.1 on described discharge pipe 2, described rear pump 2.1 has been arranged in parallel two, the rear end of described discharge pipe 2 is connected in parallel to the first drainer feeding pipeline 3 and the second drainer feed back pipeline 4, the rear end of described the first drainer feeding pipeline 3 is connected with the charging aperture of the first drainer, the rear end of described the second drainer feed back pipeline 4 is connected with the feedback outlet of the second drainer 1, be provided with inlet valve 3.1 on described the first drainer feeding pipeline 3, be provided with liquid level sensor 1.1 on described the second drainer 1, be provided with operation circuit 5 between described liquid level sensor 1.1 and inlet valve 3.1, be provided with fluid level controller 5.1 on described operation circuit 5.
