AI Technical Summary
Existing laboratory suction filtration devices are prone to corroding the vacuum pump when dealing with acidic, alkaline or organic liquids and are inefficient in operating, especially when multiple samples are required.
A simple porous suction and filtration device in the laboratory was designed, using 3 suction and filtration bottles and spherical air pumping pipes. The water pressure is adjusted through the faucet to achieve suction and filtration, avoiding the use of vacuum pumps.
The simultaneous suction filtration of multiple samples is achieved, which improves work efficiency, reduces detection costs, and avoids the problem of acid or alkaline gases and water vapor contamination and corrosion of vacuum pumps.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of suction filtration, and specifically to a simple porous suction filtration device for a laboratory. Background Art
[0002] At present, the existing filtration device in the laboratory is composed of a vacuum filter, a Buchner funnel, and a filtration bottle. When in use, a vacuum is formed inside the filtration bottle through a vacuum pump, and the liquid inside the funnel is sucked into the filtration bottle, thereby achieving solid-liquid separation. With respect to the existing related technologies, the inventor believes that there are the following defects: when filtering acidic, alkaline or organic liquids, the vacuum pump will be corroded, and even damaged, and the cost of use is high. The vacuum pumps on the market usually have only two holes. When the number of samples to be filtered is large, the number of filtrations can only be increased, and the work efficiency is low.

[0004] The technical scheme of the utility model is as follows: a simple laboratory porous filtration device, comprising: a spherical suction tube, a suction bottle one, a suction bottle two and a suction bottle three, characterized in that a Büchner funnel three is arranged above the suction bottle three, the suction port of the suction bottle three is connected to the right suction port of the suction bottle two through a rubber hose, a Büchner funnel two is arranged above the suction bottle two, the left suction port of the suction bottle two is connected to the right suction port of the suction bottle one through a rubber hose, a Büchner funnel one is arranged above the suction bottle one, the left suction port of the suction bottle one is connected to the right suction port of the spherical suction tube through a rubber hose, and the suction port above the spherical suction tube is connected to a faucet through a rubber hose.
[0005] Preferably, the first and second suction flasks are double-hole suction flasks.
[0006] Preferably, the faucet above the spherical air extraction pipe can adjust the water pressure to control the filtration speed without using a vacuum pump.
[0007] The beneficial effects of the utility model are:
[0008] The utility model adopts three filtration bottles, which can realize the simultaneous filtration of three samples. The number of double-hole filtration bottles can also be increased, and the filtration holes can be increased, thereby improving work efficiency. The filtration speed is controlled by adjusting the water pressure of the faucet. There is no need to use a vacuum pump, and there is no problem of acidic or alkaline gas and water vapor contamination and corrosion of the vacuum pump. The device used is simple and reduces the detection cost. BRIEF DESCRIPTION OF THE DRAWINGS
