Problems solved by technology

[0004] However, in this prior art, when other speeds are measured, the method of pressure sensors is adopted, and it can be obtained by cooperating with calculations. While the process is cumbersome, it makes the pipelines and other parts of the whole equipment more complicated, and in actual sampling In the process, it only describes the insertion into the pulverized coal pipeline, but does not record whether there is a sealing part, that is, there is a problem of sealing. In the actual use process, if the sampling part enters the pulverized coal pipeline, it is easy to ignore the sealing problem Gas leakage is caused, and in the case of no sampling, a part is required to seal the sampling point. Failure to solve the sealing problem will easily affect the use of the portable sampling device

Embodiment 1

[0028] Such as figure 1 and figure 2As shown, the novel portable pulverized coal pipeline sampling device of this embodiment includes a pulverized coal pipeline, and the surface of the pulverized coal pipeline is installed with a fixed pipe head 17 through the surface. A socket pipe 2 is detachably installed on the pipe head 17, the two are connected to each other, and the pipe diameter and length of the socket pipe 2 are relatively large, and a sampling gun 1 is installed in the socket pipe 2 through a switch sealing mechanism, and the sampling gun One end of 1 extends to the pulverized coal pipeline, and the sampling gun 1 is actually socketed with the socket pipe 2. During operation, the sampling gun 1 is inserted into the pulverized coal pipeline through the socket pipe 2 and the fixed connection pipe head 17, and the sampling gun The other end of 1 extends out of the socket pipe 2, that is, the existing part is outside the socket pipe 2, and the interior of the sampling...

Embodiment 2

[0037] The structure of the new portable pulverized coal pipeline sampling device in this embodiment is basically the same as that of the new portable pulverized coal pipeline sampling device in Embodiment 1, the difference is that a sealing member is installed between the sealing plug 15 and the sampling gun 1 The sealing part comprises snap ring 20, cushion block 21 and curved surface block 22, and curved surface block 22 is installed on the end surface of sealing plug 15, and the outer surface of curved surface block 22 is connected with socket pipe 2 by screw thread, and the inside of curved surface block 22 A slope is provided, and the snap ring 20 is installed on the surface of the sampling gun 1 adjacent to the sealing plug 15. The snap ring 20 is used in conjunction with the curved block 22, and the spacer 21 is installed in the gap between the snap ring 20 and the curved block 22. The spacer 21 Ring-shaped rubber block structure (see image 3 ). The snap ring 20 actu...

Abstract

The invention discloses a novel portable pulverized coal pipeline sampling device. The device comprises a pulverized coal pipeline, a fixedly-connected pipe head is installed on the surface of the pulverized coal pipeline, a socket pipe is detachably installed on the fixedly-connected pipe head, a sampling gun is installed in the socket pipe through a switch sealing mechanism, and double-pipeline arrangement is adopted in the sampling gun. A speedometer is mounted on the surface of the outer extending part of the sampling gun far away from the pulverized coal pipeline, and a separator is detachably mounted on the outer extending end surface of the sampling gun. A negative pressure suction device is mounted at an outlet in the top end of the separator, one end of the negative pressure suction device is connected with the sampling gun through a control mechanism, a pressure regulating valve is installed at the other end of the negative pressure suction device, and an air source mechanism is installed on the pressure regulating valve. According to the pulverized coal pipeline sampling device, a series of structures are arranged, so that the pulverized coal pipeline sampling device is convenient to move, the sealing effect during detection can be guaranteed while a plurality of pulverized coal pipelines are detected respectively, the operation is convenient, and the pulverized coal pipeline sampling device has a back-blowing anti-blocking function.

Description

technical field [0001] The invention relates to the technical field of coal power production, in particular to a novel portable pulverized coal pipeline sampling device. Background technique [0002] The fineness of pulverized coal is directly related to the combustion efficiency of boilers in thermal power plants. Therefore, taking samples of pulverized coal in the pulverized coal pipeline and analyzing the fineness of pulverized coal is one of the daily key tasks of thermal power plants. At present, the pulverized coal sampling devices of thermal power plants are still mainly installed on the pulverized coal pipelines, which need to be installed in every pulverized coal pipeline. The required equipment is large and the overall price is expensive, which limits the pulverized coal sampling The device is widely used in thermal power plants. [0003] In order to solve the above problems, in the prior art, such as the authorized announcement number CN201716216U named as a port...
