Dust collecting device for environment detection

Abstract

The invention discloses a dust collection device for environment detection, which comprises a dust collection mechanism and a dust suction mechanism, the dust collection mechanism structurally comprises a base, a dust suction pipe and a wind direction cover, a dust discharge port is formed in the rear lower side wall of the dust suction pipe, and the bottom end of the dust suction pipe is horizontally and rotatably connected with the base through a support column. A waterproof net is fixed to the front end of the dust suction pipe, dust filtering cloth is fixed to the rear end of the dust suction pipe, exhaust holes are formed in the side wall of the wind direction cover, the front end of the wind direction cover is rotationally connected with the dust suction pipe, a sampling ring is fixed to the inner side wall of the wind direction cover, and the inner ring side wall of the sampling ring is attached to the outer side wall of the dust suction pipe. Eight communicated through holes uniformly formed in the sampling ring and the wind direction cover are sampling holes, and a sampling bottle is inserted into each sampling hole; the dust collection mechanism is arranged in the dust collection pipe and the wind direction cover and is connected with the sampling ring through the linkage mechanism. Dust can be conveniently and directly collected in different periods, and the situation that dust is inconvenient to collect in the leeward state is avoided.

Description

technical field [0001] The invention relates to the technical field of dust collection devices, in particular to a dust collection device for environmental detection. Background technique [0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure the state of environmental quality. Environmental monitoring is to determine the status of environmental pollution and the level of environmental quality by monitoring and measuring indicators reflecting environmental quality. [0003] Air quality testing is an item of environmental testing, in which the content and type of dust in the air is an indicator. A Chinese patent discloses an energy-saving dust collection device for environmental testing (authorized announcement number CN113654961A). However, firstly, the diameter of the collection tube is small, and the suction area is small, and the test results are affected by the size of the space and the wind direction; seco...

[0003] Air quality testing is an item of environmental testing, in which the content and type of dust in the air is an indicator. A Chinese patent discloses an energy-saving dust collection device for environmental testing (authorized announcement number CN113654961A). However, firstly, the diameter of the collection tube is small, and the suction area is small, and the test results are affected by the size of the space and the wind direction; secondly, the period of time-segmented collection is greatly affected by the weather temperature, which has no reference value for comparison ; Its 3rd, directly collect air with air bag and carry out dust content detection, also need worker to classify air and dust, have increased user's workload
