Bottle,suction bottleneck lateral margin is fixedly connected with threeway plug valve, is provided with sucking filtration interface on the right side of threeway plug valve, and oil pump, by the sucking filtration interface on the right side of the second rubber tube union three way cock valve, is provided with pressure relief opening on the downside of threeway plug valve；The bottleneck of bottle,suction is that top diameter is more than ground in the glass of base diameter；
The inertance tube outer wall of buchner funnel lower end is provided with ball milling mouth, and the lateral wall of ball milling mouth is suitable with the bottleneck medial wall of bottle,suction, is provided with core plate inside buchner funnel.
Ball milling is clamped between the bottleneck outer wall of bottle,suction and ball milling mouth upper end.
This utility model has the advantages that
1, bottle,suction bottleneck have employed top diameter more than ground technique in the glass of base diameter, have employed glass bead ground on the long-neck tube wall of buchner funnel lower end, both coordinate, and air-tightness is good, ne-leakage, need not smear grease, can saving filtration leather cup, assembly and disassembly is convenient；
2, bottle,suction bottleneck lateral margin is fixedly connected with threeway plug valve, connects oil pump flatly, uses as relief valve with atmosphere flatly；
3, bottle,suction lower lip is fixedly connected with discharging tube, and discharging tube is provided with plug valve；
4, between bottle,suction with buchner funnel, use ball milling is clamping determines to be connected, it is possible to effectively prevent bottle,suction and buchner funnel from occurring vibrations or inclination to affect the sealing cooperation of the two when coordinating.
In sum, this utility model is reasonable in design, simple in construction, a kind of assembly and disassembly of offer convenient, be prone to experimental implementation and the simple and easy sucking filtration experimental provision of one of energy quick pressure releasing, and work efficiency obtains and is greatly improved.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of simple and easy sucking filtration experimental provision, including bottle,suction 1, support 2, buchner funnel 3, ball milling folder 4, waste liquid cylinder 5 and oil pump 6, bottle,suction 1 is placed on support 2, bottom bottle,suction 1, lateral margin is fixedly connected with discharging tube 7, discharging tube 7 is provided with plug valve 8, and waste liquid cylinder 5 is by the first rubber tube 9 connected drainage pipe 7；
Bottleneck 10 lateral margin of bottle,suction 1 is fixedly connected with threeway plug valve 11, is provided with sucking filtration interface 12 on the right side of threeway plug valve 11, and oil pump 6, by the sucking filtration interface 12 on the right side of the second rubber tube 18 union three way cock valve 11, is provided with pressure relief opening 13 on the downside of threeway plug valve 11；The bottleneck 14 of bottle,suction 1 is that top diameter is more than ground in the glass of base diameter；
Inertance tube 15 outer wall of buchner funnel 3 lower end is provided with the ball milling mouth 16 of glass, and the lateral wall of ball milling mouth 16 is suitable with bottleneck 14 medial wall of bottle,suction 1, and buchner funnel 3 is internal is provided with core plate 17.
Ball milling folder 4 is clamped between bottleneck 14 outer wall of bottle,suction 1 and ball milling mouth 16 upper end.
Bottle,suction 1, plug valve 8, buchner funnel 3, threeway plug valve 11, ball milling folder 4, waste liquid cylinder 5 and oil pump 6 belong to prior art, and its specific structural features is not described in detail.
Work process of the present utility model: first bottle,suction 1 is placed on support 2, closes the plug valve 8 on lateral margin discharging tube 7 bottom bottle,suction 1, and first rubber tube 9 one end is socketed on discharging tube 7, and first rubber tube 9 other end is passed in waste liquid cylinder 5.Then the ball milling mouth 16 on inertance tube 15 outer wall of buchner funnel 3 lower end is docked with bottle,suction 1 ring flange ground bottleneck 14, grease need not be smeared and can realize being tightly connected.Ball milling is pressed from both sides 4 and is clamped between bottle,suction 1 bottleneck 14 outer wall and ball milling mouth 16 upper end, it is prevented that when bottle,suction 1 and buchner funnel 3 coordinate, occur vibrations or inclination to affect the sealing cooperation of the two.Again the threeway plug valve 11 at bottleneck 10 place of bottle,suction 1 being adjusted UNICOM's oil pump 6 and the state of bottle,suction 1, pressure relief opening 13 is in closed mode.Second rubber tube 18 one end is socketed on sucking filtration interface 12, and second rubber tube 18 other end is socketed on the bleeding point of oil pump 6.On the core plate 17 within buchner funnel 3, filter paper is spread after above Job readiness is appropriate, pour the material needing solid-liquid separation into buchner funnel 3, open oil pump 6 and start the sucking filtration that reduces pressure, along with unlatching and the negative pressure of oil pump 6 increase, material in buchner funnel 3 is in the process that negative pressure extraction and filter paper core plate 17 are filtered, liquid material is by sucking filtration to bottle,suction 1, and solid fraction material is stayed in buchner funnel 3, and solid-liquid separation completes.Threeway plug valve 11 is adjusted UNICOM's pressure relief opening 13 and the state of bottle,suction 1, makes bottle,suction 1 lead to air, so that the negative pressure state within bottle,suction 1 releases, close oil pump 6, complete whole sucking filtration process.Finally opening the plug valve 8 on bottle,suction 1 bottom drain 7, the liquid material in bottle,suction 1 flows into waste liquid by rubber tube 9 and gathers in cylinder.
Shape of the present utility model, material, structure etc. are not done any pro forma restriction by the present embodiment; every any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, belongs to the protection domain of technical solutions of the utility model.
