Description

A kind of air-flowing type detects pipe end bell jar device

Technical field

The utility model is related to a kind of air-flowing type detection pipe end bell jar device, is mainly used in air-flow method measurement pipe end End.

Background technology

In the middle of liquid phase reactor production process, the SOLUTION PROPERTIES parameter inside reaction medium decides the efficiency of reaction, root According to these parameters, the process of reaction can be speculated and detected, so as to improve reaction efficiency, promote the carrying out of production reaction.Surveying During the nature parameters of quantitative response solution inside, wherein the situation in gas-liquid contact face can often reflect many property of solution Matter, therefore be frequently necessary to be measured using gasometry in production process.But gas-liquid contact face and unstable, tend to Fluctuated with the change of air-flow, so can not only influence the Stability and veracity of measurement result, also easily cause suck-back, shadow The normal of the equipment of sound is used.Therefore it is necessary that developing a kind of both can ensure that uses safety, can ensure detection data accuracy again Air-flow method with stability measures the bell jar shape device of pipe end.

Utility model content

The purpose of this utility model is to overcome above shortcomings in the prior art, and provides a kind of structure design and close Reason, can effectively prevent solution suck-back, while ensureing the air-flowing type detection pipe end bell jar device of outlet uniformity.

The technical scheme in the invention for solving the above technical problem is：The air-flowing type detects pipe end bell jar device bag Appendix is included, its design feature is：Also include bell jar, the opening for having a cavity, the cavity in the bell jar is located at clock The bottom of cover, connector is provided with the top of the bell jar, and the connector is connected with the cavity of bell jar, one end of the appendix Connector with bell jar is connected.

Preferably, the bottom of bell jar described in the utility model is provided with a circle bell jar edge, the bell jar edge is song Linear structure.

Preferably, 3-10 times of a diameter of gas transmission pipe diameter of bell jar described in the utility model.

The utility model compared with prior art, with advantages below and effect：1. bell jar is used at the gas-liquid contact of bottom Design, increases contact surface so that testing result is more accurate；2. the bell jar bigger than gas transmission pipe diameter is used in gas transmission pipe end Design, increases the saturation of solution, in effectively preventing solution suck-back to appendix, it is ensured that the security that equipment is used；3. The curved design at bell jar edge so that outlet is evenly, it is ensured that the stability of detection data.

Appendix of the present utility model is used to convey test gas, and the two ends of appendix connect source of the gas and bell jar respectively.Clock Cover is installed in the end of appendix, and the position below liquid level to be measured.Bell cover structure is designed with beneficial to increase gas-liquid contact Face, prevents interference, it is ensured that the accuracy of testing result；Additionally, cross section of the cross-sectional area of bell jar much larger than gas pipeline, its Internal relatively large space can accommodate more solution, effectively prevent solution and enter into the inside of appendix and cause down The situation inhaled and block, it is ensured that using for appendix is safe.

The utility model middle bell jar size is set to be associated with the size of appendix, if cross section is excessive, can be caused Limited air-flow is difficult to uniform spilling, influences the accuracy of measurement result；If bell jar cross-sectional area is too small, air-flow overflows too fast It is uneven so that testing result fluctuation is big, and detection data is unstable.Generally, the 3-10 of a diameter of gas transmission pipe diameter of bell jar Times, the accuracy of testing result can be ensured in the range of this, also cause detection data stabilization.

Bell jar edge design curve in the utility model, this bends design can increase bell jar edge and liquid The contact surface in face so that gas uniformly and stably overflows from curved brim, it is ensured that the stability of testing result.

Fig. 1 is the structural representation of air-flowing type detection pipe end bell jar device in the utility model embodiment.

In figure：1st, reaction medium；2nd, appendix；3rd, bell jar；31st, bell jar edge.

Specific embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following examples are right It is of the present utility model explanation and the utility model is not limited to following examples.

Embodiment.

Referring to Fig. 1, the air-flowing type detection pipe end bell jar device in the present embodiment includes appendix 2 and bell jar 3, bell jar 3 Inside there is a cavity, positioned at the bottom of bell jar 3, the top of bell jar 3 is provided with connector for the opening of cavity, the connector and bell jar 3 cavity connection, the connector connection of one end and bell jar 3 of appendix 2.The bottom of bell jar 3 is provided with a circle bell jar edge 31, Bell jar edge 31 is curve-like structure.3-10 times of the diameter of a diameter of appendix 2 of bell jar 3.

Air-flowing type detection pipe end bell jar device in the present embodiment chooses two common pipelines as logical when making With the appendix 2 of type air-flowing type ore pulp concentration meter.One cross-sectional area of design is the bell jar 3 of 5 times of gas pipeline, and by its bottom Curve is designed as bell jar edge 31 in edge.The top of bell jar 3 is connected to the end of appendix 2, the air-flowing type ore pulp is completed Other connections of densimeter.

The above-mentioned air-flowing type ore pulp concentration meter containing bell jar 3 being completed is attached in the middle of reaction solution to be measured, and Bell jar 3 is placed to the liquid level of reaction medium 1, is measured.During measurement, measurement gas passes through appendix 2 Enter in the middle of bell jar 3, then be spilled in the middle of reaction medium 1 from bell jar edge 31 under the influence of air pressure, finally overflow from liquid level Go out.In the process, the pressure in the gas-liquid face for being formed in bell jar is detected so as to reach the purpose of detection.

Furthermore, it is necessary to explanation, the specific embodiment described in this specification, is named the shape of its parts and components Claiming etc. can be with difference, and the above content described in this specification is only to the utility model structure example explanation.
