Abstract
The utility model relates to a liquid level control system of a heat medium feeding tank. The liquid level control system for the heat medium feeding tank is characterized by comprising a heat medium feeding tank (1), a feeding pipeline (2), a feeding back pipeline (3) and a heat medium furnace (4). A discharging outlet of the heat medium feeding tank (1) is connected with a charging inlet of the heat medium furnace (4) via the feeding pipeline (2); the front segment of the feeding pipeline (2) is provided with feeding pumps (2.1); the rear segment of the feeding pipeline (2) is provided with a flow transmitter (2.2); the middle segment of the feeding pipeline (2) is connected with a feeding back mouth of the heat medium furnace (4) via the feeding back pipeline (3); the feeding back pipeline (3) is provided with a feeding back valve (3.1); a control circuit (5) is arranged between the feeding back valve (3.1) and the flow transmitter (2.2); and the control circuit (5) is provided with a flow controller (5.1) The liquid level control system for heat medium feeding tank is advantageous in that the liquid level control precision is high and the control system is labor saving.
Description
Technical field
The utility model relates to a kind of heating agent feeding tank, relates in particular to a kind of heating agent feeding tank tank level control system, belongs to the chemical industry equipment field.
Background technology
In producing PET Process, need to carry out feeding to hot Media Oven with the heating agent feeding tank, the more difficult control of liquid level in traditional heating agent feeding tank, need to regulate the speed of heating agent feeding tank to feeding in hot Media Oven manually.For the maximization production line, if need workman's manual operation, waste a large amount of artificial, and the more difficult assurance of heating agent feeding tank liquid level control accuracy.Therefore seek a kind of liquid level control accuracy higher, save artificial heating agent feeding tank 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 artificial heating agent feeding tank tank level control system.
The purpose of this utility model is achieved in that
A kind of heating agent feeding tank tank level control system, it comprises the heating agent feeding tank, feed lines, feed back pipeline and hot Media Oven, between the discharging opening of described heating agent feeding tank and the charging aperture of hot Media Oven, by feed lines, be connected, the leading portion of described feed lines is provided with feeding pump, described feeding pump has been arranged in parallel two, the back segment of described feed lines is provided with flow transmitter, the stage casing of described feed lines is connected with the feedback outlet of hot Media Oven by the feed back pipeline, be provided with material returning valve on described feed back pipeline, be connected with control circuit between described material returning valve and flow transmitter, be provided with flow controller on described control circuit.
Compared with prior art, the beneficial effects of the utility model are:
The utility model passes through the aperture of the signal controlling material returning valve of control circuit, thereby controls the rate of feeding of heating agent feeding tank to hot Media Oven, guarantees that heating agent feeding tank liquid level is able to accurate control.It is higher that this heating agent feeding tank tank level control system has the liquid level control accuracy, saves artificial advantage.
