Embodiment 1

[0027] Such as figure 1 As described above, implementing a conical airflow field atomization injection device is composed of a dust removal end cover 4 and a housing 1. The diameter of the end face of the connection between the dust removal end cover 4 and the housing 1 is Φ120mm, and the length of the dust removal end cover 4 is 48mm, the length of the housing 1 is 202mm, the outer diameter of the housing throat 18 is Φ60mm, the inner diameter of the housing throat 18 is Φ50mm, and the diameter of the end of the channel 16 is Φ74mm. The dust removal end cover 4 and the shell 1 are connected by three bolts 3, and the gaskets selected for connection should be thin copper sheets, which can ensure that the tapered ring gap formed by the dust removal end cover 4 and the shell 1 remains unchanged and It is convenient to disassemble the dust removal end cover and the shell, and its performance is stable; the dust removal end cover 4 is provided with a water pipe inlet 7, a vent hole...

Abstract

The invention relates to an atomizing and spraying device of a conical air flow field. The device is characterized in that a dustproof end cap is fixedly arranged on a casing to form a conical annular seam, a generating line of the conical annular seam and an axis form an included angle, the conical annular seam forms a spraying angle of the conical air flow field, the center of the dustproof end cap is provided with a water pipe inlet, the periphery of the center of the dustproof end cap is uniformly provided with eight ventilation holes in the circumferential direction, the connecting part of the dustproof end cap and the casing is provided with a compressed air inlet which is communicated with compressed air, and the pipe diameter of the casing is gradually increased from interior to exterior to form a horn-shaped passage structure. The atomizing and spraying device has the advantages that a mechanical rotary part and a power source are not arranged, so the safe production of coal mines is favorable, the spraying and atomizing effects are good, and the coverage range of water mist is large; the structure is simple, and the convenience in use is realized; and the noise is less, and the working is safe and reliable.

Description

technical field [0001] The invention relates to an atomization injection dust suppression device, in particular to a cone-shaped airflow field atomization injection device used in the coal mining process. Background technique [0002] The improvement of the degree of mechanization has resulted in more and more coal dust generated during the coal mining process. Dust sources mainly come from coal mining face, tunneling face, coal transportation and reloading points, etc. Coal dust not only affects the underground working environment, but also seriously endangers the physical and mental health of employees. Working in a high-concentration coal dust environment for a long time can easily make employees suffer from pneumoconiosis. In addition, when coal dust reaches a certain concentration, it is easy to cause explosion accidents, causing casualties and economic losses. [0003] In the prior art, wet dust removal is adopted for dust removal, and a good dust reduction effect ha...
