Compared with the prior art, the utility model the advantage be: the utility model discloses can carry out accurate measurement to esterification reaction cauldron's liquid level, not influenced by ambient temperature, life is longer, can effectively reduce manufacturing cost and workman's the amount of labour, convenient operation, safe and reliable is stable.
Description
Technical Field
The utility model relates to a liquid level measurement system especially relates to a novel polyester device esterification reaction cauldron liquid level measurement system.
Background
In chemical fiber polyester production enterprises and factories, a double-flange liquid level meter of a polyester esterification reaction kettle has the advantages that as a medium in the reaction kettle is high in temperature and corrosive, a flange diaphragm can be corroded and influenced in long-term operation, the service cycle is shortened (remarks are that the flange diaphragm on the positive pressure side is not easy to corrode and damage in normal use, the flange diaphragm on the negative pressure side is easy to corrode and influenced by environmental temperature, the capillary flow conductivity is poor, and the liquid level measurement greatly fluctuates), and the measured liquid level fluctuates along with the fluctuation of the environmental temperature (such as weather change), so that the liquid level of the reaction kettle cannot be accurately displayed. Moreover, the accessories are long in purchase period and can be replaced only when the vehicle is stopped for maintenance. Therefore, the development of a novel liquid level measuring system for an esterification reaction kettle of a polyester device is an urgent problem to be solved by the technical personnel in the field.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve above-mentioned not enough, the utility model provides a novel polyester device esterification reaction cauldron liquid level measurement system.
The above object of the present invention is achieved by the following technical solutions: a novel liquid level measuring system of an esterification reaction kettle of a polyester device comprises the esterification reaction kettle, a single-flange liquid level transmitter, a pressure taking valve, a pressure guiding pipe and an isolation tank, wherein the positive pressure side of the single-flange liquid level transmitter is connected with a flange through a capillary tube; the isolation tank and the pressure guide pipe are filled with isolation liquid for transmitting the pressure of the negative pressure side; and the positive pressure side of the single-flange liquid level transmitter is connected to a flange port at the bottom of the esterification reaction kettle.
Furthermore, a discharge valve is arranged on the isolation tank.
After the liquid level measurement system is installed, debugging the liquid level measurement system, and transferring the negative pressure side measuring range to reach the normal measuring range of liquid level measurement; when the liquid level of the esterification reaction kettle rises, the pressure is increased, and the environmental temperature changes, the liquid level measuring system is not influenced, the liquid level measurement is accurate, and the measurement is stable.
Compared with the prior art, the utility model the advantage be: the utility model discloses can carry out accurate measurement to esterification reaction cauldron's liquid level, not influenced by ambient temperature, life is longer, can effectively reduce manufacturing cost and workman's the amount of labour, convenient operation, safe and reliable is stable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, a novel polyester device esterification reaction kettle liquid level measurement system comprises an esterification reaction kettle 1, a single-flange liquid level transmitter 2, a pressure taking valve 3, a pressure drawing pipe 4 and an isolation tank 5, wherein the positive pressure side of the single-flange liquid level transmitter 2 is connected with a flange 7 through a capillary 6, and a flange port at the top of the esterification reaction kettle 1 is sequentially connected with the pressure taking valve 3 and the isolation tank 5 through the pressure drawing pipe 4 and then is connected to the negative pressure side of the single-flange liquid level transmitter 2 through the pressure drawing pipe 4; the isolation tank 5 and the pressure guiding pipe 4 are filled with isolation liquid for transmitting the pressure of the negative pressure side; and the positive pressure side of the single-flange liquid level transmitter 2 is connected to a flange port at the bottom of the esterification reaction kettle 1.
Further, a discharge valve 8 is arranged on the isolation tank 5.
After the liquid level measurement system is installed, debugging the liquid level measurement system, and transferring the negative pressure side measuring range to reach the normal measuring range of liquid level measurement; when the liquid level of the esterification reaction kettle 1 rises, the pressure is increased, and the environmental temperature changes, the liquid level measuring system is not influenced, the liquid level measurement is accurate, and the measurement is stable.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
