The utility model discloses a rational in infrastructure, the interior pressure of the cauldron body is led through and is filtered gas pitcher intercommunication drip chamber, makes the stability of drip chamber pressure balance assurance dropping liquid progress.

However, in the utility model, the filter gas jar directly communicates with the drip chamber through the constant voltage pipe is direct, leads to the drip chamber to be contaminated easily to the accuracy that leads to the reaction and the quality of reaction liquid error appear.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: aiming at the problem of communication between a dropping liquid tank and a gas filtering tank in the prior art, a water-based dropping device for resin is provided.

The utility model adopts the technical scheme as follows:

a water-based dripping device for resin comprises a kettle body, wherein the upper part of the kettle body is communicated with a dripping tank body, a piston which can reciprocate along the axis of the dripping tank body is arranged in the dripping tank body, the piston divides the dripping tank body into a constant pressure chamber and a dripping chamber, and the constant pressure chamber and the dripping chamber are respectively communicated with the kettle body.

Further, the dropping liquid tank body is horizontally arranged.

Further, an inner cylinder is horizontally fixed on the drip chamber, one end of the inner cylinder is closed, and a pressure regulating film is arranged at the other end of the inner cylinder; the bottom of inner tube is provided with the dropwise add hole, is provided with communicating pipe in the dropwise add hole, communicating pipe and the cauldron body intercommunication.

Furthermore, the inner cylinder is eccentrically arranged in the liquid dropping chamber.

Further, the axis of the inner barrel is located below the axis of the drip chamber.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses in, the pressure differential between the cauldron body and the drip chamber is balanced through the piston of the internal portion of dropping liquid jar, avoids the siphonage that the pressure differential leads to. Meanwhile, the constant pressure chamber and the drip chamber are isolated by the piston, so that the constant pressure chamber communicated with the inside of the kettle body is prevented from polluting dripping liquid in the drip chamber. Simultaneously, the setting of inner tube and pressure regulating membrane can also avoid the pressure variation direct influence of constant-pressure chamber to the speed of adding of the interior inner tube of dropping liquid chamber's dropping liquid, and simultaneously, the inner tube eccentric settings does benefit to further reduction pressure variation to the influence of pressure regulating membrane, and then reduces the influence to dropping liquid speed of adding.
