At present, set up the extraction opening on the feed cylinder of extruder, the extraction opening is direct to be bled through exhaust tube connection vacuum pump, has a small amount of material to spill over, and this part material gets into the water mixture formation waste water in vacuum pump and the vacuum pump, can not directly discharge, need carry out waste water treatment, causes the waste of water resource.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome above-mentioned not enough, provide a sheet extruder's vacuum water circle device, set up the vacuum buffer chamber and prevent that the material from spilling over, set up circulation tank and further intercept very little material through the filter screen, make the outer water reuse of discharging of water ring vacuum pump, water circulation between circulation tank and the water ring vacuum pump, the water economy resource reduces the unnecessary extravagant greatly.
The purpose of the utility model is realized like this:
the utility model provides a sheet extruder's vacuum water circle device, includes vacuum buffer chamber, water ring vacuum pump and circulating water tank, circulating water tank is equipped with circulation water inlet and circulation delivery port, and the sheet extruder feed cylinder is equipped with the extraction opening, the sealed top that sets up at the extraction opening of vacuum buffer chamber, vacuum buffer chamber lateral wall is equipped with the switching mouth, the switching mouth passes through the exhaust tube and is connected with the induction port of water ring vacuum pump, the delivery port of water ring vacuum pump passes through the outlet pipe and is connected with circulation water inlet, the circulation delivery port passes through the inlet tube and is connected with the water inlet of water ring vacuum pump, the circulation water inlet is located circulating water tank's upper portion, and the circulation delivery port is located circulating water tank's lower part, be equipped with the filter screen between.
Preferably, the distance between the lowest position of the adapter port and the bottom surface of the vacuum buffer chamber is 5.5-8 cm.
Preferably, the filter screen is positioned at the upper part of the circulating water tank and below the circulating water inlet.
Preferably, the filter screen can be dismantled, the filter screen is equipped with the frame, circulation tank corresponds the frame and is equipped with the step, the frame card is on the step.
The utility model has the advantages that:
the utility model discloses set up the vacuum buffer chamber and prevent that the material from spilling over, set up circulation tank and further intercept very little material through the filter screen, make the outer water reuse that discharges of water ring vacuum pump, hydrologic cycle between circulation tank and the water ring vacuum pump, the water economy resource greatly reduces unnecessary extravagant.
