Description
Technical field
The utility model relates to the manual Suction filtration device of a kind of use for laboratory, belongs to equipment of chemical industry technical field.
Background technology
Suction filtration refers to and utilizes air extractor to take out the pressure in bottle,suction into negative pressure, thus realizes the unit operations of Separation of Solid and Liquid.In many chemical experiments, all can use Suction filtration device obtain product.Suction filtration device conventional at present comprises Buchner funnel, filter paper, bottle,suction and air extractor, and wherein conventional air extractor is vavuum pump.The better air-flow of vavuum pump suction filtration effect is large and steady, but its volume is comparatively huge too heavy.Conventional vavuum pump all needs the use that switches on power, and needs pumping fluid, can cause certain pollution to environment.If, filtrate suck-back phenomenon also can be there is in the misoperation when using vavuum pump.For avirulent Separation of Solid and Liquid problem, use the process of vavuum pump comparatively loaded down with trivial details, and suction filtration work cannot be completed when power-off or vavuum pump are broken down.
Although also there are some manual Suction filtration device in existing market, also there are some such as suction filtration air-flows in use and be interrupted discontinuous or that equipment cost is higher problem.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to use, and installing/dismounting is simple, can the manual Suction filtration device of use for laboratory of suction filtration continuously, to overcome the deficiencies in the prior art.
The technical solution of the utility model is: this device comprises band valve funnel, bottle,suction, pressure vacuum gauge, suction interface, pump bowl, and the filler tube of band valve funnel enters bottle,suction through the bottle stopper on bottle,suction bottleneck.The bottom of bottle,suction is provided with band valve discharging tube, and side, top is provided with suction filtration mouth and suction interface is threaded connection, and inlay rubber film in suction interface, opposite side is provided with pressure vacuum gauge interface and pressure vacuum gauge is threaded connection.Suction interface is connected with pump bowl by screw thread.Pump bowl comprises cylindrical shell, piston, pull bar composition, and this piston is made up of upper and lower two sheet pistons, and upper slice piston has bar hole, and containing a cavity in the middle of upper and lower two panels piston, this cavity is embedded with a rubber ring.
And, with the interface be threaded, rubber sheet gasket is housed each, ensures sealing.
And, funnel with valve, by valve closing before putting into liquid-solid mixture, until bottle,suction have certain vacuum spend time, open valve, realize continuous suction filtration, pressure vacuum gauge plays the effect of vacuum in instruction bottle,suction.
And in pump bowl, the diameter of upper and lower two panels piston is slightly less than pump bowl diameter, and the rubber ring in cavity can roll in cavity.
Advantage of the present utility model and good effect are:
All parts of the present utility model is all demountable, and bottle,suction can also be connected with vavuum pump, realizes electronic suction filtration; Bottle,suction is furnished with pressure vacuum gauge, is used to indicate vacuum in bottle,suction; With valve on funnel, when manual suction filtration, realize continuous suction filtration; For the simple Separation of Solid and Liquid problem of solution, can realize easy and simple to handle, institute take up space little, filtrate can not the object such as suck-back.
