Description

Auxiliary device for suction filtration

Technical Field

The utility model relates to an auxiliary device for suction filtration belongs to the appurtenance field for the suction filtration.

Background

Vacuum filtration is to pour the solid-liquid mixture to be separated into Buchner funnel (containing filter paper and filter membrane), the liquid component is pressed into beaker under the action of the pressure difference between external atmospheric pressure and negative pressure of vacuum pump suction opening, the solid is left above the filter paper, so as to achieve the purpose of solid-liquid separation. For the suction filtration process, the existing equipment connection is that a buchner funnel is connected on the mouth of a suction flask, filter paper is placed on the buchner leak, a hose is connected on the body of the suction flask, and the hose is connected with an air pump. The existing equipment combination has no problem in function realization, but is lower in the actual use process because of suction filtration efficiency, and when carrying out relevant experiments in a centralized manner, the existing suction filtration equipment can not meet the requirements of users far away, and if a plurality of sets of equipment are adopted for testing, the problems of large occupied area and high cost of the equipment exist.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a suction filtration auxiliary device that can increase suction filtration process efficiency can overcome the not enough of prior art.

The technical scheme of the utility model is that: auxiliary device for suction filtration, it includes uncovered staving, is equipped with the aspirating hole on the staving of uncovered staving, is equipped with the outlet of taking the valve in the below of uncovered staving, is equipped with sealed bung in the top of uncovered staving, is equipped with the funnel jack more than two on sealed bung, is equipped with the stopple by every funnel jack.

The auxiliary device for suction filtration is characterized in that the funnel jack is cylindrical or the lower section of the funnel jack is cylindrical and the upper end of the funnel jack is conical, and flexible rubber is arranged in the funnel jack.

In the auxiliary device for suction filtration, a hose is connected to the suction hole.

The auxiliary device for suction filtration is characterized in that a pipe plug is connected to the air suction hole, the outer wall of the pipe plug is matched with the air suction hole, an air outlet hole connected with a hose is formed in one end of the pipe plug, a gas distributing hole is formed in the other end of the pipe plug, a gas introducing pipe is connected to the gas distributing hole, and an outlet of the gas introducing pipe is opposite to a funnel opening placed on a funnel jack.

Compared with the prior art, the utility model discloses the problem to current suction filtration inefficiency has set up an auxiliary device for suction filtration, the device does not change current suction filtration principle, it trades current buchner flask for uncovered staving, be equipped with the aspirating hole on the staving of uncovered staving, be equipped with the outlet of taking the valve in the below of uncovered staving, be equipped with sealed bung in the top of uncovered staving simultaneously, be equipped with the funnel jack more than two on sealed bung, be equipped with the stopple by every funnel jack, such uncovered staving just can place a plurality of buchner funnels on an uncovered staving (buchner flask) with the sealed bung cooperation of taking the funnel jack, and then raise the efficiency, the funnel jack that does not insert the funnel can seal with the stopple, it is more convenient to make its use. The lower section of the funnel jack is columnar, the upper end of the funnel jack is conical, and the funnel jack can improve the tightness and increase the placing stability of the Buchner funnel; be equipped with flexible rubber in the funnel jack, can further increase the leakproofness like this, and can avoid buchner funnel damage, can adjust funnel male degree of depth because of sufficient resistance simultaneously, make a plurality of funnel faces of inserting on it not at the coplanar, and then utilize the space, increase funnel insertion quantity. Be connected with the stopcock on the aspirating hole, the outer wall and the aspirating hole cooperation of stopcock, be equipped with the venthole of being connected with the hose in the one end of stopcock, be equipped with gaseous diffluence pass at the other end of stopcock, be connected with the bleed pipe on gaseous diffluence pass, the bleed pipe export is relative with the flare opening of placing on the funnel jack, multiplicable evacuation effect like this further improves suction filtration effect and efficiency.
