Description
Technical field
This utility model relates to a kind of polyether monomer reactor feeding controlling device, belongs to chemical production equipment field.
Background technology
In polyether monomer production process, each raw material needs to be quantitatively adding in reactor and participates in reaction, and can the control accuracy of raw materials amount determine reaction and carry out in the intended manner. Existing technology is to arrange electromagnetic valve at feed pipe, weighing result according to meausring apparatus controls the opening and closing of electromagnetic valve, to control feeding quantity, but it is relatively low to there is control accuracy, especially when certain raw materials amount is bigger, when feed pipe flow velocity is very fast, the more difficult control of charging precision, it addition, when certain electromagnetic valve controlling to feed in raw material breaks down, whole production system needs to stop transport, and affects production efficiency.
Summary of the invention
This utility model provides a kind of polyether monomer reactor feeding controlling device, the specific scheme is that
A kind of polyether monomer reactor feeding controlling device, including meausring apparatus, feed pipe and controller, described meausring apparatus is arranged on bottom reactor, and feed pipe one end connects with reactor, and the other end connects with raw material storage tank; Described feed pipe is also associated with backup line, and backup line connects with reactor; Being provided with valve between feed pipe and backup line, feed pipe and backup line are provided with electromagnetic valve; Feed pipe was also associated with filter, flow control valve and check valve successively before electromagnetic valve; Described controller is connected with each flow control valve and electromagnetic valve, and is connected with meausring apparatus; Described controller is provided with flow-control module.
Further, described feed pipe and backup line inwall are provided with anticorrosive coat.
Further, described feed pipe is additionally provided with temperature transmitter, and temperature transmitter is arranged between filter and flow control valve, and is connected with controller.
Useful point of the present utility model is in that, this device can realize auto feed control, by arranging flow control valve at feed pipe, flow velocity can be reduced before having fed in raw material, electromagnetic valve is turned off when having fed in raw material, the control accuracy of feeding quantity can be improved when flow velocity is less, additionally, flow rate calculation feeding quantity when can pass through reinforced, reference as the meausring apparatus bottom reactor, the feeding quantity error caused during single dependence meausring apparatus can be avoided because of fault, it is possible to improve the reliability of whole production system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
