Embodiment Construction

[0009] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0010] It can be seen from the accompanying drawings that the vertical shaft gun excavation wave-controlled spray type smoke and dust removal device of this program includes a water inlet pipe 14 and a sprinkler 15 connected to the water inlet pipe 14. The water inlet pipe 14 is provided with a first A control valve 10, the first control valve 10 is fixed with a first control pin 7, the first control pin 7 is fixed on a fixture 16 through a first tension spring 9, the front end of the first control pin 7 is provided with a A second control pin 6 engaged with a control pin 7, the second control pin 6 is connected to one end of a lever 2 with a pin shaft 3 through a second tension spring 5, and the pin shaft 3 is the support point of the lever 2. The other end of the lever 2 is fixed w...

Abstract

The invention provides a technical scheme of a wave-controlled spray-type fume and dust removing device for use in vertical shaft blasting and digging. In the device adopting the scheme, a water inlet pipe is provided with a first control valve having a first control bolt which is fixed on a wall body by a first tension spring and provided with a second control bolt which pulls the first control bolt, the second control bolt is connected with a lever by a second tension spring, and the other end of the lever is fixed with an impact wave screen; and the end, connected with a spray thrower, of the water inlet is also connected with a second control valve, and the other end of the second control valve is connected with an eccentric water tank which is on the same side of the first control bolt as the first tension spring and is connected with the first control bolt through a pushing rod. The scheme makes up for the drawback that a single fume and dust removal way is adopted in vertical shaft construction and fulfils the aim of removing fume and dust in vertical shaft blasting and digging by using impact waves and wave-controlled spray technology.

Description

Technical field: [0001] The invention relates to a dust removal device, in particular to a vertical shaft gun excavation wave control spray type smoke and dust removal device. Background technique [0002] In mine construction, it is necessary to excavate by blasting, that is, mining in the form of blasting. TNT explosives are usually used during blasting. After the explosives explode, a large amount of smoke and dust will be produced. The smoke and dust contain nitrogen pentoxide, which will poison people's blood. Death by suffocation, only dinitrogen pentoxide diluted to a certain extent, will not cause harm to the human body, and a large amount of smoke is also harmful to the human body. [0003] The existing method for diluting nitrogen pentoxide is: after detonation, open the air duct to send air down the well for 20-30 minutes, and the smoke and dust will be discharged upward along the well shaft, but in the process of air supply, some special situations will occur, su...
