Description

Anti-blocking sampling device for fastening and anti-falling

Technical Field

The utility model relates to the technical field of wind pressure anti-blocking samplers, in particular to a fastening anti-falling anti-blocking sampling device.

Background

The anti-blocking sampler is a device arranged between a (air supply) process pipeline of a hearth of the coal-fired boiler or a wind and dust mixture and a wind pressure transmitter, and has the main functions that: the air pressure measuring device can prevent impurities (particles, dust and the like) in air or smoke from entering the air pressure measuring pipeline and the instrument, avoid blockage of a measuring channel, cause unstable or distorted display of the instrument, improve the measuring effect after the anti-blocking sampler is installed, and play a damping role.

The common anti-blocking sampler has simple structure and convenient installation, but is easy to accumulate dust and block for measured points with higher concentration of dust or particulate matters, and the reliability is greatly reduced after long-term use, so that a novel anti-blocking sampling device is provided; because the sampler is arranged at the pressure pipeline mouth, under the high pressure, high temperature and vibration of the pipeline, the anti-blocking sampling device has the potential safety hazard of loosening and unstable connection, and once high-temperature gas and particulate matters are sprayed out in a large quantity, the anti-blocking sampling device is dangerous. The existing partial blockage cleaning and purging process cannot be synchronously performed with the pressure measurement of the measuring instrument, and the measuring pipeline is isolated and cannot work. If the conventional manual cleaning flow is adopted, the whole pipeline is opened, and a large amount of gas and particulate matters are sprayed out, so that potential safety hazards exist.

Therefore, an anti-blocking sampling device which can be stably and firmly installed, has a better blocking clearing effect and can synchronously work with a pressure measuring instrument is needed to meet the working requirement of the environment of the existing anti-blocking sampler.
