Problems solved by technology

However, due to the expansion of the space, the local eddy current phenomenon occurs in the dust-laden airflow, and the dust circulation channel has many bends. Therefore, while sampling the dust, the dust in the dust-laden airflow will pollute the sampling element, the accuracy of the sampling element will decrease, and the measurement data will be easily obtained. Deviation, short maintenance period of equipment, etc.
[0004] For example, the dust concentration sensors disclosed in application numbers 201010294093.5 and 200820028964.7 all disclose that they can work continuously in a dusty environment, but they have the shortcomings of many bends in the dust circulation channel and easy generation of eddy currents. The applicant adopts the device with this structure It is found that there are problems of short service life and frequent maintenance

Embodiment 1

[0031] like figure 1 As shown, a dust concentration sensor includes a sampling head, an air intake pipe 1', a detection base 2', a laser 3', a light extinction cylinder 4' and an air outlet pipe 6', and a darkroom 5' is provided in the detection base 2'. The sampling head is connected to one end of the air intake pipe 1', the other end of the air intake pipe is connected to the upper end of the detection base, the lower end of the detection base is connected to the air outlet pipe 6', and the other end of the air outlet pipe is connected to the fan. When irradiated into a dark room, the extinction tube can receive laser light. Among them, the sampling head has a corner, and the rest of the dust airflow circulation channels are vertical straight-through channels. The dust airflow passes through the sampling head and enters the air intake pipe, then enters the dark room, and then flows out through the air outlet pipe. In the dark room, the light generated by the laser is scatte...

Embodiment 2

[0033] The applicant provides a new mine dust concentration sensor by studying the reason why the dust concentration sensor is susceptible to contamination.

[0034] like Figure 2-5 As shown, a mine dust concentration sensor includes a sampling head 1, an air intake pipe 2, a detection base 3, an air outlet pipe 4, a dust measurement assembly 5, a signal processing assembly 6 and a power device 7; the detection base 3 is provided with The dark room 31; the dust measuring assembly 5 includes a laser generator 51 and a light extinction cylinder 52; the signal processing assembly 6 includes a photoelectric receiver 61 and a microprocessor (not shown in the figure); The laser generator 51, the extinction cylinder 52 and the photoelectric receiver 61, the laser generator 51 and the extinction cylinder 52 are arranged opposite; The air outlet end of the air outlet pipe 4 is communicated with the power device 7; the mining dust concentration sensor also includes an air outlet nozzl...

Abstract

The invention relates to a mine dust concentration sensor, comprising a sampling head, an air induction pipe, a detection base, an air outlet pipe, a dust measurement component, a signal processing component and a power device; the detection base is provided with a dark room; the dust measurement component includes Laser generator and extinction cylinder; the signal processing assembly includes a photoelectric receiver and a microprocessor; the side of the darkroom is provided with the laser generator, extinction cylinder and photoelectric receiver, and the laser generator and extinction cylinder are arranged opposite to each other One end of the air-inducing pipe is communicated with the sampling head, and the other end is communicated with the upper end of the darkroom; the outlet end of the air outlet pipe is communicated with the power unit; the mine dust concentration sensor also includes a circular platform-shaped air outlet The upper bottom surface of the air outlet nozzle communicates with the lower end of the dark room, and the lower bottom surface communicates with the air inlet end of the air outlet pipe. The mine dust concentration sensor of the invention greatly improves the anti-dust pollution ability of the sampling chamber and reduces the amount of equipment maintenance.

Description

technical field [0001] The invention belongs to the field of mining equipment, in particular to a mine dust concentration sensor. Background technique [0002] Dust endangers the health of workers, threatens mine safety, and shortens the service life of equipment and instruments. It is one of the five natural disasters common in coal mines in my country. Dust monitoring is the premise and basis for dust prevention and control. At present, there are three main types of dust monitoring instruments in my country: dust samplers, dust detectors and dust concentration sensors. [0003] Among them, the dust concentration sensor has the characteristics of convenient dust concentration detection, high detection accuracy and good repeatability. The current dust concentration sensor sampling mostly adopts the pipeline structure. The working method of dust sampling is generally to install sampling elements, luminous sources, extinction cylinders, etc. in a certain position of the pipe...
