Abstract
The utility model provides a film sealing bag tank for storing liquid. The film sealing bag tank for storing liquid is provided with a tank body provided with a liquid inlet and a liquid outlet, and the top surface of the tank body is provided with a manhole opening The inner of the tank body is provided with a flexible film sealing bag which is corresponding to the inner cavity of the tank body after installed. The bag opening external side of the film sealing bag is matched with the manhole opening of the tank body along the sealing. The film sealing bag tank for storing liquid can accomplish the injection and the exhausting of the liquid in the tank body, and simultaneously, the isolating sealing of the liquid in the tank body with the atmosphere is realized. The film sealing bag tank for storing liquid is especially suitable for the storing of the volatile liquid of hydrochloric acid, ammonia, oil, etc., so as to prevent the liquid volatilization loss, fire and explosion. The film sealing bag tank for storing liquid is also suitable for non-volatilized liquid such as the salt water, high-purity water, alkaline solution, sulfuric acid etc., so as to prevent the storage liquid from absorbing the carbon dioxide, oxygen, and moisture in the air, making the degree of purity concentration lower and causing the pollution of liquid matter. Compared with the existing liquid level sealing tank of storing liquid, the film sealing bag tank for storing liquid has the advantages of simple structure, low cost of installation, and good sealing effect.
Description
Technical field
The utility model relates to liquid storage container, is a kind of film bag sealing fluid reservoir specifically.
Background technology
The liquid that some is used to produce is need seal with isolated from atmosphere in the process of container storage.Volatile liquids such as hydrochloric acid, ammoniacal liquor, some oils for example, be the loss that prevents to evaporate, fire prevention, explosion-proof and prevent from environment produced and pollute, involatile liquid such as salt solution, high-purity water, alkaline solution, sulfuric acid, purity, concentration are reduced and cause liquid matter to pollute for preventing to absorb carbon dioxide in air, oxygen, moisture content, all need use liquid storage container with sealing protection.The container that is used for the aforesaid liquid sealed storage at present mainly contains baton round liquid level sealing fluid reservoir.Because baton round is about 90% to the coverage rate of liquid level, so its sealing effectiveness is bad, and because the productive costs height of baton round makes the sealing establishment charges big, the deployment cost that causes sealing fluid reservoir improves greatly.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of good sealing effect is provided, the film bag sealing fluid reservoir that deployment cost is low.
The technical scheme that realizes above-mentioned purpose is: a kind of film bag sealing fluid reservoir, tank body with configuration liquid inlet and outlet, on the end face of tank body, offer man-hole opening, be equipped with the fexible film sealing bag that matches with tank inner chamber after expanding in tank body, the sack outside of its sealing bag and the man-hole opening on the tank body are along being sealed and matched.
The technical solution of the utility model also comprises: be provided with the rain-proof dust-proof cap above man-hole opening.
The utility model is simple in structure, and deployment cost is low, and good sealing effect can satisfy the interior sealed storage requirement of jar of all kinds of volatile liquids and involatile liquid.
Description of drawings
Accompanying drawing is this film bag sealing liquid storage tank structure scheme drawing.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described:
Provide as accompanying drawing, this fluid reservoir has the tank body 3 of configuration liquid inlet and outlet 1 and 2, on the end face of tank body, offer man-hole opening 5, be equipped with the fexible film sealing bag 4 that matches with tank inner chamber after expanding in tank body, the sack outside of its sealing bag 4 and the man-hole opening on the tank body are along being sealed and matched.
Tank body 3 of the present utility model can be all kinds of liquid container jars that adopt various forming materials, the setting of its liquid inlet and outlet 1,2 also is not limited only to tank base, man-hole opening 5 also can be provided with two as required, the plastic sheeting that sealing bag 4 is fit to adopt intensity height, flexibility and air-tightness good, rubber film and do not constitute with the film of seal fluid generation chemical reaction, sealing sack and being sealed and matched of tank body man-hole opening can be adopted the modes that are sealed and matched such as bonding, that collar is fixed, resilient ring fraps.For preventing that in use rainwater and dust are in sack enters sealing bag, above man-hole opening 5, be provided with rain-proof dust-proof cap 6, the structure of its rain-proof dust-proof cap can adopt as shown in drawings, column through placing the man-hole opening periphery is fixed on the top of man-hole opening with the cap body, also can adopt the cap body of band side direction pore to be assemblied on the man-hole opening and constitutes.
When the utility model is specifically implemented, sealing bag is put into tank body from man-hole opening, inflate in bag through sack, it is closely connected on tank skin that bag is expanded, simultaneously with the air that retains between bag and jar inwall outside man-hole opening is driven out tank body, finish the sealing of sealing sack and tank body man-hole opening afterwards and fix, promptly finish the assembling of sealing bag and tank body.When inlet injects liquid in tank body, sealing bag and liquid level contact portion rise with liquid level, and it is closely connected with tank skin that all the other pocket portion keep under atmospheric effect, makes pot liquid and atmospheric isolation, finish in jar inject liquid in, realize sealing to jar stored liquid.When through liquid outlet when jar effluxes out liquid, the sealing bag part that contacts with liquid level descends with liquid level, and the above sealing bag of liquid level partly keeps closely connected with jar inwall, in finishing jar storaging liquid to jar outside smoothly in the discharge, the sealing of realization pot liquid.
The utility model is equally applicable to be called as the liquid container of liquid reserve tank.
Claims (2)
1, a kind of film bag sealing fluid reservoir, tank body (3) with configuration liquid inlet and outlet (1) and (2), on the end face of tank body, offer man-hole opening (5), it is characterized in that: be equipped with the fexible film sealing bag (4) that matches with tank inner chamber after expanding in tank body (3), the sack outside of sealing bag and the man-hole opening on the tank body are along being sealed and matched.
