Description

Tar sampler

Technical Field

The utility model relates to a coal coking field, concretely relates to tar sampler.

Background

Coal tar is a black or brown liquid, also called coal , the smell is similar to naphthalene or aromatic hydrocarbon, it is a by-product when dry distillation coal is used to make coke and gas, the tar needs to be sampled when being detected and analyzed, the sampling is mainly carried out from a tar pipeline, but the pipeline has a certain pressure when sampling, the tar flow is unstable at the moment of opening a valve during sampling, thus easily causing splashing and influencing the safety of personnel.

SUMMERY OF THE UTILITY MODEL

In order to solve the existing problems, the utility model provides a tar sampler.

The utility model discloses a realize through following technical scheme:

the utility model provides a tar sampler, includes coal tar pipeline and the fixed sampling tube of lower part intercommunication, the sampling tube exit end is connected with the baffle-box, the baffle-box includes shell body, the interior casing of coaxial integrative setting, form the annular chamber between shell body, the interior casing, interior casing upper portion is fixed with sampling tube exit end intercommunication, it has the overflow hole with the annular chamber intercommunication to open on the interior casing, the root of shell body sets up the sample collecting pipe with the annular chamber intercommunication, sample collecting pipe bypass center of connection connecting pipe and through its and interior casing bottom intercommunication.

The top of baffle-box opens has the gas vent with interior casing intercommunication, the shell body of baffle-box is just being provided with the peephole of bar to overflow hole department, is provided with sealed peep cover on this peephole, peephole one side is provided with the volume of getting scale mark in overflow hole lower part.

Install first control valve on the central connecting pipe, install the second control valve on the sampling collection pipe, the sampling pipe is provided with the ball valve with coal tar pipeline connection root.

Compared with the prior art, the beneficial effects of the utility model are that: this practicality sets up the baffle-box of sample at the sampling tube, and tar is stable when guaranteeing the sample, and the security improves greatly, can also realize the accuracy nature of sample volume simultaneously, prevents extravagant tar under the condition of satisfying the sample volume.

FIG. 2 is a schematic perspective view of the partial structure of FIG. 1;

in the figure: coal tar pipeline 1, sampling tube 2, ball valve 21, buffer tank 3, shell body 4, interior casing 5, annular chamber 6, overflow hole 7, sample collecting pipe 8, central connecting pipe 9, first control valve 10, second control valve 11, gas vent 12, peephole 13, volume of getting scale mark 14.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1 and 2, a tar sampler comprises a coal tar pipeline 1 and a sampling pipe 2 fixed to the lower part of the coal tar pipeline, wherein the outlet end of the sampling pipe 2 is connected with a buffer tank 3, the buffer tank 3 comprises an outer shell 4 and an inner shell 5 which are coaxially and integrally arranged, a ring cavity 6 is formed between the outer shell 4 and the inner shell 5, the upper part of the inner shell 5 is fixed to the outlet end of the sampling pipe 2, an overflow hole 7 communicated with the ring cavity 6 is formed in the inner shell 5, a sampling collecting pipe 8 communicated with the ring cavity 6 is arranged at the root of the outer shell 4, and the bottom of the sampling collecting pipe 8 is communicated with the bottom of the inner shell through a bypass connecting center connecting pipe 9.

The top of buffer tank 3 is opened has the gas vent 12 with interior casing 5 intercommunication, the shell body 4 of buffer tank 3 is just being provided with bar peephole 13 to overflow hole 7 department, is provided with sealed peep hole 13 on, peephole 13 one side is provided with the volume of getting scale mark 14 in overflow hole 7 lower part.

The central connecting pipe 9 is provided with a first control valve 10, the sampling collecting pipe 8 is provided with a second control valve 11, and the connecting root part of the sampling pipe 2 and the coal tar pipeline 1 is provided with a ball valve 21.

The working principle is as follows: during the sample, open ball valve 21 on sampling tube 2, tar that has pressure in the coal tar pipeline 1 enters into 5 insides of the interior casing of baffle-box 3, gas in the interior casing 5 is discharged from gas vent 12, tar increase in the interior casing 5 can overflow to annular chamber 6 along overflow hole 7, observe through peeping hole 13 when 6 liquid levels of annular chamber reach the volume of getting scale mark 14, close ball valve 21 and open second control valve 11, place the sampling bottle at sample collecting pipe 8 exit end, stable tar is taken out in annular chamber 6 like this to the overflow, after first sampling bottle is full, put second sampling bottle and open first control valve 10 in sample collecting pipe 8 lower part, take out

interior casing

5 and 6 tar of annular chamber all, the accuracy of sample volume can be realized to the volume of getting scale mark 14 that sets up, prevent extravagant tar under the condition of sample volume. The whole sampling process is stable, and the safety is greatly improved.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
