Embodiment Construction

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0026] figure 1 It is a structural schematic diagram of the automatic high-precision dust collector of the present invention. Such as figure 1 As shown, the dust collector includes two parts: a dynamic dust collection system driven by a windvane and a box-type static dust collection system. The dynamic dust collection system driven by the wind vane is arranged on the top of the equipment casing 12 and above the box-type static dust collection system. The accuracy of the dust collector is 6 mg to 20 mg. In this embodiment, the dust collection The accuracy of the device is 20 mg.

[0027] The windvane-driven dynamic dust collection system includes a sand inlet 4, a first air leakage net 2, a second air leakage net ...

Abstract

The present invention relates to a fully automatic and high-precision dust and sand collector, which comprises a vane-driven dynamic dust and sand collection system and a box-type static dust and sand measurement system. The box-type static dust and sand collection system is arranged in an equipment shell, and the vane-driven dynamic dust and sand collection system is arranged at the top of the equipment shell and on the box-type static dust and sand collection system. The fully automatic and high-precision dust and sand collector realizes ideal combination of dynamic collection and static weighing of dust and sand in the windward direction during dust and sand collection, the dust and sand are guided into the box-type static dust and sand collection system from the vane-driven dynamic dust and sand collection system via a hollow shaft, the real-time dynamic measurement of the collected dust and sand is achieved, historic breakthroughs are made in the measurement precision and resolution through multi-level weighing, the measurement range is greatly improved, and the high-precision, high-frequency, long-cycle and fully automatic monitoring is actually achieved. The precision of the dust and sand collector is 6-20mg.

Description

technical field [0001] The invention relates to a dust collector, in particular to a fully automatic high-precision dust collector, which belongs to the field of environmental monitoring. Background technique [0002] my country is a country that suffers from severe wind and sand erosion disasters, and the phenomenon of land desertification is serious. In order to study this change, wind speed and wind erosion were observed in many scientific experiments, and various dust collectors were also designed. Some of these collectors use manual collection methods, some use semi-automatic collection methods, and some recent designs use automatic collection methods, but none of them can work for a long period of time and comprehensively and accurately record the dust process automatically. There is an urgent need for an automatic collector that can automatically record and accurately reflect changes in sand and dust, and can automatically measure for a long period of time to fully r...
