This device also comprises latex volume pump motor, latex volume pump and latex manual valve; The front end of described latex under meter links to each other with the latex volume pump by the latex discharge nozzle; Described latex volume pump one end connects latex volume pump motor, and the other end connects the latex manual valve.
This device also comprises formic acid volume pump motor, formic acid volume pump and formic acid manual valve; The front end of described formic acid under meter links to each other with the formic acid volume pump by the formic acid discharge nozzle; Described formic acid volume pump one end connects formic acid volume pump motor, and the other end connects the formic acid manual valve.
This device also comprises control panel; Described control panel is installed on the frame outside surface.
Control the variable-frequency motor rotating speed of latex volume pump motor and formic acid volume pump motor by control panel, realize changing in proportion automatically of both flows, so that by line mixer the time, glue acid blending ratio keeps constant, thereby guarantees the quality conformance of natural rubber.
This device also comprises the latex feed-pipe; Described latex feed-pipe is connected with the latex manual valve.
This device also comprises the formic acid feed-pipe; Described formic acid feed-pipe is connected with the formic acid manual valve.
This device also comprises universal wheel; Described universal wheel is installed in the frame bottom, is used for making things convenient for device to move.
The utility model is by the real-time traffic of latex and formic acid in the under meter detection pipeline, adopt control panel to receive and handle flow signal, the variable-frequency motor rotating speed of control latex and the used volume pump of formic acid, realize changing in proportion automatically of both flows, so that by line mixer the time, glue acid blending ratio keeps constant, guarantees the consistence of natural rubber quality, and overcome the solid inhomogeneous influence to the natural rubber quality of acid cure, thereby improved control accuracy.
At least need 3 posies because traditional technology and stream add sour link, control latex flow, formic acid flow respectively and flow effect, adopt this device back only to need 1 post to get final product, therefore, the utility model can also reach saves labour's intensity and cost.
