The utility model has the advantages that: the suction bottle is divided into an upper suck-back cavity and a lower liquid storage cavity by the partition board arranged in the suction bottle, so that when the suck-back phenomenon occurs in the process, suck-back water is cached in the suck-back cavity, the pollution to filtrate is avoided, and the suction bottle is convenient to use in the experimental process; the liquid outlet pipe of the funnel is inserted into the liquid inlet pipe in the process through the liquid inlet pipe arranged on the partition plate, so that the collection of filtrate in the process is realized; through feed liquor pipe and drain pipe not zonulae occludens, there is great gap between the two to make things convenient for pouring out of the back filtrating that the in-process suction filtration finishes and collect, gaseous intercommunication among the on the other hand also guarantees the device, makes going on that the suction filtration operation can be smooth.
Drawings
Fig. 1 is a schematic view of a negative pressure suction filtration device for preventing reverse suction.
Detailed Description
The negative pressure suction filtration device for preventing reverse suction of the present invention will be further described with reference to the accompanying drawings.
In figure 1, 1-funnel, 2-rubber buffer, 3-buchner flask, 4-suck-back chamber, 5-stock solution chamber, 6-drain pipe, 7-feed liquor pipe, 8-exhaust tube, 9-rubber hose, 10-vacuum pump.
A funnel 1 of a negative pressure suction filtration device for preventing back suction is used for adding liquid into a suction filtration bottle 3. The rubber stopper 2 increases the sealing of the device, carrying the funnel 1 mounted thereon. The filter flask 3 serves as a space for storing the filtrate. The suck-back cavity 4 stores suck-back water, so that the suck-back water is cached in the suck-back cavity 4, thereby avoiding pollution to filtrate and being convenient for use in the experimental process. The liquid storage cavity 5 stores the filtrate which is pumped and filtered into the suction filter flask 3. The outlet pipe 6 serves as a passage port in the funnel 1 for adding filtrate to the filter flask 3. Feed liquor pipe 7 makes suck-back chamber 4 and stock solution chamber 5 intercommunication for during the drain pipe 6 of in-process funnel injects this feed liquor pipe, thereby realized the in-process to the collection of filtrating, there is great gap between the two, with the collection of pouring out of the back filtrating of being convenient for the suction filtration of the preceding in-process finishes, gaseous intercommunication among the on the other hand also guarantees the device, makes going on that the suction filtration operation can be smooth. The suction tube 8 carries a rubber hose 9 mounted thereon. The rubber hose 9 serves as a passage medium for pumping pressure into the filter flask 3. The vacuum pump 10 realizes pressure reduction and pressure pumping, so that negative pressure is formed in the suction filtration bottle 3, and the suction filtration is accelerated.
A rubber plug 2 is arranged on the mouth of a suction flask 3 of a negative pressure suction filtration device for preventing suck-back, the rubber plug 2 is connected with a funnel 1, and a liquid outlet pipe 6 extends out of the lower end of the funnel 1 to the inside of the suction flask 3; a partition board is arranged in the middle of the interior of the suction flask 3, wherein the suction flask 3 is divided into an upper suck-back cavity 4 and a lower liquid storage cavity 5 by the partition board; meanwhile, an upward liquid inlet pipe 7 is arranged on the partition plate to enable the two cavities to be communicated, and a liquid outlet pipe 6 just penetrates into the liquid inlet pipe 7; meanwhile, an exhaust tube 8 is arranged on one side of the back suction cavity 4, a rubber hose 9 is arranged outside the exhaust tube 8, and the other end of the rubber hose 9 is connected with a vacuum pump 10.
When the negative pressure suction filtration device capable of preventing reverse suction is used, a funnel 1 is installed and a vacuum pump 10 is connected; in the process, the vacuum pump 10 is turned on to realize the suction filtration process, and in the process, filtrate is directly pumped into the liquid storage cavity 5 through the liquid outlet pipe 6 of the funnel 1, so that the filtrate is stored and poured out after the filtration is finished; in case the suck-back phenomenon has taken place for the in-process, the water of suck-back then can be collected in suck-back chamber 4 through feed liquor pipe 7, can not mix with filtrating and cause the pollution of filtrating to the use in the laboratory of being convenient for more.
The utility model provides a negative pressure suction filtration device capable of preventing reverse suction, which avoids the pollution to filtrate and is convenient for use in the experimental process; the collection of pouring of filtrating after the suction filtration finishes of being convenient for, gaseous intercommunication among the on the other hand also guarantees the device for suction filtration operation can be smooth go on advantage, current suction filtration experiment has been overcome, the in-process of suction filtration is because reason or misoperation of equipment, the phenomenon of suck-back can appear very easily, then water in the vacuum pump then can be sucked back to the suction flask in, thereby cause the pollution of filtrating, lead to the problem of the failure of experiment, this device market potential is big, promote on market.
