Abstract
The utility model relates to a liquid seal and storage device. The device comprises a liquid storage tank, wherein the tank body of the liquid storage tank is cylindrical, is provided with a feed liquor tube at the upper part and a liquid discharge tube at the bottom, is a pressure liquid storage tank, and adopts a pressure-resistant sealing structure; and a pressure pipeline is arranged at the upper part of the tank body, provided with a pressure gauge, and connected with an external pneumatic control system. According to the utility model, pressure in the liquid storage tank is controlled by the external pneumatic control system, so that pressure difference is generated between the outside of the tank body and the inside of the tank body, and the pressure difference is utilized to pump and discharge the liquid.
Description
Technical field
The utility model relates to liquid storaging device, specifically refers to a kind of hydraulic seal storage device.
Background technology
Present liquid storaging device, major part is that the tank body at holding vessel is provided with inlet and liquid outlet, inlet and liquid outlet connecting tube, at pipeline infusion pump is set and carries out drawing liquid and Raft liquid, so just must be provided with vent at tank body, so just so that the tank body sealing effectiveness is bad, be unfavorable for the storage of some volatile liquids, simultaneously, because the volatile combustible products that contains ethanol one class of some liquid, for getting rid of potential safety hazard, infusion pump must adopt air pump, and drawing liquid Raft liquid efficient is more bad; Also have some comparatively valuable chemical liquids, adopt the tank body with inner bag that liquid is stored, such storage device has higher requirements to the quality of inner bag, and structure is comparatively complicated, and storage cost is high.
Summary of the invention
The utility model is to provide a kind of hydraulic seal storage device, the tank body of holding vessel adopts withstand voltage hermetically-sealed construction, by the ambient pressure control system pressure of fluid reservoir tank body is controlled, made the tank body inside and outside form pressure reduction, utilize pressure reduction to carry out drawing liquid and Raft liquid.
The technical solution of the utility model is: a kind of hydraulic seal storage device, comprise fluid reservoir, the tank body of fluid reservoir is cylindrical, the tank body top is provided with feed tube, and the bottom is provided with drain pipe, and described fluid reservoir is the pressure fluid reservoir, tank body adopts withstand voltage hermetically-sealed construction, the tank body top is provided with pressure pipeline, is provided with compression indicator on the pressure pipeline, and described pressure pipeline is connected to extraneous pneumatic control system.
Described fluid reservoir is equipped with the water level sight cell.
Be respectively arranged with corresponding the first valve, the second valve and the 3rd valve on described feed tube, drain pipe and the air-pressure duct.
Described fluid reservoir bottom even distributes is provided with four supporting legs.
Advantage of the present utility model: the utility model is simple in structure, with low cost, be convenient to make and use, the tank body leak tightness of holding vessel is fabulous, be fit to apply to some liquid with volatile substances are stored, simultaneously, by the pneumatic control system in the external world pressure of fluid reservoir tank body controlled, utilize pressure reduction to carry out drawing liquid and Raft liquid, the efficient of drawing liquid Raft liquid is higher.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Now embodiment is described in further detail structure of the present invention by reference to the accompanying drawings for the ease of it will be appreciated by those skilled in the art that:
With reference to figure 1, a kind of hydraulic seal storage device comprises fluid reservoir, and the tank body 1 of fluid reservoir is cylindrical, and the top of tank body 1 is provided with feed tube 2, and feed tube 2 is connected to fluid supply by extraneous pipeline; The bottom of tank body 1 is provided with drain pipe 3, is provided with the first valve 2-1 at described feed tube 2, and drain pipe 3 is provided with the second valve 3-1; Described fluid reservoir is the pressure fluid reservoir, and tank body 1 adopts withstand voltage hermetically-sealed construction, and the top of tank body 1 is provided with pressure pipeline 4, and pressure pipeline 4 is provided with compression indicator 4-2 and the 3rd valve 4-1, and described pressure pipeline 4 is connected to extraneous pneumatic control system.
Described fluid reservoir is equipped with water level sight cell 5, and water level sight cell 5 is the transparent pipes with scale that are provided with the metal coating shell, and screened housing does not coat the scale position of transparent pipe, and water level sight cell 5 is communicated with tank body 1.
Described fluid reservoir bottom even is provided with four supporting legs 6, is used for supporting the tank body 1 of holding vessel, and the drain pipe 3 that the bottom of tank body 1 is provided with is arranged on the center of four supporting legs.
Workflow of the present utility model is as follows:
1. feed tube 2 is connected with extraneous pipeline, is connected to fluid supply to be stored by extraneous pipeline, closes the first valve 2-1 and the second valve 3-1;
2. open the 3rd valve 4-1, the gas that the air pump of extraneous pneumatic control system starts tank body 1 extracts, make the inside and the extraneous negative pressure that forms of tank body 1, when the compression indicator 4-2 that is provided with when pressure pipeline 4 reaches certain value, open the first valve 2-1, air pump continues operation simultaneously, keeps the value of compression indicator 4-2 constant, by suction function, will wait to store is the draws fluid holding vessel;
3. carry out water level by water level sight cell 5 and observe, when water level reaches certain position that air pump is out of service, close the 3rd valve 4-1, after liquid no longer enters holding vessel, close the first valve 2-1, with fluid storage;
4. when the liquid that stores need to be discharged use or be entered next process, drain pipe 3 is connected with extraneous pipeline, open the 3rd valve 4-1, the air pump of extraneous pneumatic control system starts squeezes into tank body 1 inside with gas, make tank body 1 air pressure inside greater than the external world, when the compression indicator 4-2 that is provided with when pressure pipeline 4 reaches certain value, open the second valve 3-1, air pump continues operation simultaneously, keep manometric value constant, by differential pressure action, the liquid of holding vessel inside is discharged holding vessel enter next process.
The above only is preferred embodiment of the present utility model, and all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
