Abstract

This programme discloses a kind of bottle,suction in experiment equipment field, including bottle, and bottle is provided with multiple passages, and multiple passages are located at the both sides of the bottle, and the passage of bottle both sides is symmetrical arranged on the axis of bottle；The sealing ring for sealing the passage is additionally provided with bottle, the inwall of sealing ring is provided with air channel, and air channel connects with the passage, and the ring body of the sealing ring is provided with aspirating hole, and aspirating hole connects with the air channel.This programme sets air channel and aspirating hole respectively by setting passage and sealing ring, then in the inside and outside wall of sealing ring, makes to be interconnected between passage, aspirating hole and air channel；And multiple passages are symmetrical on the vertical plane for crossing axis；So that active force caused by flowing out the air-flow in symmetrical passage is cancelled out each other so that bottle,suction is more steady, avoids its situation about being fallen down by gas shock from occurring.

Description

A kind of bottle,suction

Technical field

Experiment equipment field is the utility model is related to, more particularly to a kind of bottle,suction.

Background technology

Filtering is to make suspension under gravity or the effect of other external force（Or containing solid particle heating gas）In liquid （Or gas）Through medium, solid particle and other materials are retained by filter medium, so that solid and other materials and liquid （Or gas）The operation of separation.Wherein, the filtering of solid-liquid suspension is most commonly seen；Natural filtration is used during filtering or was depressurized Filter.When carrying out natural filtration, funnel is placed on the annulus of iron stand, then filter paper is placed on funnel, uses filtering flask Receive filtrate；Due in filter process, fully relying in gravity, whole filter process takes more.In order to solve normal pressure mistake The problem of filter is time-consuming more, carried out at present using the mode being filtered under diminished pressure, it is general first on the pad of the bottom surface of funnel when use Filter paper, funnel is injected into bottle,suction upper opening and pour sealing joint, the solid for being then intended to separate, liquid mixture Lou into Bucket；Because bottle,suction is generally conical flask, its bottle is provided with a passage, and extract system is connected with passage；Pass through Extract system extracts the gas in bottle,suction out, and liquid component is drawn into beaker under negative pressure effect, and solid then stays in top Funnel in.

During using being filtered under diminished pressure, because extract system is when the gas in bottle,suction extracts, due to pumping process In substantial amounts of gas flowed out by the air vent on bottle,suction, the active force that its moment produces air-flow is larger；So as to cause air-flow Bottle,suction is fallen down into breaking-up.

Utility model content

The utility model is intended to provide a kind of bottle,suction, to solve the bottle,suction of prior art when being filtered under diminished pressure, Because air-flow is extracted by a passage completely, the problem of causing bottle,suction to be fallen down by gas shock.

A kind of bottle,suction in this programme, including bottle, bottle are provided with multiple passages, and multiple passages are located at The both sides of the bottle, the passage of bottle both sides are symmetrical arranged on the axis of bottle；It is additionally provided with and is used on bottle The sealing ring of the passage is sealed, the inwall of sealing ring is provided with air channel, and air channel connects with the passage, the sealing The ring body of ring is provided with aspirating hole, and aspirating hole connects with the air channel.

The working principle and beneficial effect of this programme：When being filtered under diminished pressure, extract system connection aspirating hole, start pumping System is evacuated to bottle,suction, and the gas inside bottle,suction comes out from passage, because passage is provided with multiple so that filter Gas outflow path has multiple in bottle, and passage is symmetrical on vertical plane, caused by the air-flow flowed out in relative passage Strength is cancelled out each other；Reduce the impulse force of air-flow.Because air channel connects with passage and aspirating hole, air-flow flows from passage After going out, by air channel, it is extracted through aspirating hole；During air-flow converges in air channel, due to relative wind intermolecular forces Interaction is offset, and the air-flow of aspirating hole is flowed through through air channel becomes gentle, avoids the feelings that bottle,suction is fallen down by gas shock Condition occurs.And after the gas in bottle,suction is extracted, in bottle, pressure diminishes, and negative pressure is formed with the external world, so that filtering accelerates.

Further, multiple passage ring-types are distributed on the bottle.Ring-type is uniformly arranged passage so that filters The air-flow interphase interaction formed after gas outflow in bottle, offsets or reduces mutual active force, make the extraction of air-flow more Add gently, avoid bottle,suction falls down rupture；Multiple passages is in same horizontal line in addition, ring-type is set, effectively reduce The area that passage takes on bottle,suction vertical plane, help to increase the space that bottle,suction is used to hold liquid.

Further, it is connected with screen pack in the aspirating hole.Screen pack helps to reduce the draught area of aspirating hole, when outer When boundary's extract system rate of air sucked in required is excessive, by screen pack, makes what gas in bottle,suction flowed out to measure control, reduce air-flow to taking out The impact of filter flask, be advantageous to the stabilization of bottle,suction.

Further, the bottom of bottle of the bottle,suction is fixedly connected with sucker.During using bottle,suction, sucker will be utilized by bottle,suction It is fixed in plate face, is advantageous to maintain the stabilization of bottle,suction, avoids it from being fallen down by gas shock.

Further, weight member is provided with the center of the bottle,suction bottom of bottle.By adding weight member, make bottle,suction bottom Weight is bigger, is advantageous to maintain the stabilization of bottle,suction, avoids it from being fallen down by gas shock.

Further, the weight member is spheroid.Weight member is arranged to spheroid so that the center of gravity of bottle,suction is located at bottle,suction Bottom center of gravity, so as to bottle,suction stability strengthen, avoid it from being fallen down by gas shock.
