The utility model has the advantages that: liquid is buffered in the tank, so that automatic bubble removal of the liquid is realized, and the downstream liquid mass flow meter MFC realizes accurate flow control (because the control of the MFC is seriously disturbed by the existence of bubbles), so that the process precision requirement is ensured.

Drawings

Fig. 1 is a schematic structural diagram of a debubbler buffer tank of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

Referring to fig. 1, the debubbler buffer tank includes a tank 1, and the tank 1 is used for storing liquid D4.

The bottom of the tank body 1 is provided with a feed inlet 11 and a discharge outlet 12, namely, the feed is fed from the feed inlet 11 and the discharge is discharged from the discharge outlet 12.

Feed inlet 11 communicates inlet pipe 13, and liquid D is imported to the first end of inlet pipe 13, and the second end of inlet pipe 13 extends to the inside upper end of jar body 1 and hugs closely jar inner wall of body 1. The liquid enters the feeding pipe 13 and is sprayed on the inner wall of the tank body, the bubble remover is arranged at the tail end of the pipeline system, the fluid pressure is reduced, the dissolved gas can automatically escape and is stored on the upper layer of the tank body 1, and the liquid flows down along the wall of the tank body due to gravity and is stored on the lower layer of the tank body 1.

The discharge port 12 is externally connected with a discharge pipe 14, and the discharge pipe 14 is used for discharging the liquid D4 at the bottom of the tank body 1.

Further, the feeding pipe 13 and the discharging pipe 14 are both provided with ferrule ball valves, so that the maintenance and the reconstruction of equipment are facilitated.

The outer wall of the tank body 1 is connected with a transparent PFA hose 10, the PFA hose 10 is arranged in a vertical direction, the upper end and the lower end of the PFA hose are respectively communicated with the lower end and the upper end of the tank body 1, and the PFA hose 10 is used for observing the liquid height in the tank body 1 (the function is equivalent to an observation window).

Further, the inside of jar body 1 is equipped with level gauge 15, and the level gauge is used for judging the liquid level height of jar internal portion 1.

The liquid level meter 15 has at least two judgment result points: the first judging point is arranged in the middle of the tank body 1, and the second judging point is arranged on the upper part of the tank body.

The second point of determination is slightly below the end of the feed pipe 13.

The top of the tank body 1 is also provided with an air outlet which is connected with a pneumatic control valve 16 outwards, and the pneumatic control valve is used for realizing automatic discharge of gas.

Further, the outlet of the pneumatic control valve 16 is provided with a needle valve 17 for controlling the discharge rate.

The theory of operation of bubble removal ware buffer tank do: d4 is input into the tank body 1 through the feeding pipe 13, when the liquid level in the tank body 1 reaches a first judgment point of the liquid level meter, the pneumatic control valve is opened to control the gas discharge of the tank body 1, the gas is discharged at a preset exhaust speed according to the needle valve, the liquid level in the tank rises while the gas is discharged, and when the liquid level rises to a second judgment point, the pneumatic valve is automatically closed to stop exhausting. The whole process realizes automatic bubble removal through control, and continuous production is realized through continuous feeding and discharging.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
