Shandong Dongtai supplies sealing strips, wear-resistant sealing strips for coal mines, and dust curtains

&Recently, a branch of the Agricultural Bank of China in Yangzhou Jiangdu welcomed a multi-millionaire woman named Zhuang (pseudonym). Zhuang came to withdraw money with a certificate of deposit worth 10,000 yuan. After careful identification, bank employees discovered that the deposit receipt was actually a forgery and immediately called the police. An investigation by the Jiangdu Police in Yangzhou City found that the fake deposit certificate in Zhuang's hand turned out to be the "betrothal money" given to her by her boyfriend Bao (pseudonym), but Zhuang himself did not know that the deposit certificate was fake. Currently, this weird boyfriend was arrested by the police on suspicion of forging financial instruments.
1. Composition and installation of dust curtain
Composition of dust curtain:
& Dust curtain consists of purification spray and dust curtain. The purification spray should be able to seal the entire tunnel& installation The distance between the air inlet side of the dust curtain and the dust curtain shall not be less than
.
.
The dust curtain is made of materials with good air permeability, and its shape can be the same as the cross-section of the tunnel
Installation of the dust curtain:
& The dust curtain is installed along the roof of the tunnel, and the dust curtain The size is basically consistent with the specifications of the tunnel. A relatively heavy iron rod or wooden stick is installed at the lower part of the dust curtain. The purpose is to make the dust curtain droop and seal the entire section of the tunnel. There is a sidewalk on one side of the tunnel, and the dust-proof spray is installed on the air inlet side away from the dust curtain
2. The dust reduction principle of the dust curtain:
The dust curtain has the following functions
The dust curtain has the following functions: It has blocking and filtering functions: Since the dust curtain is hung in the tunnel, the coal dust carried in the wind flow is blocked when passing through the dust curtain and is absorbed by the dust curtain. Capture, thereby reducing the concentration of coal dust in the wind flow and purifying the wind flow.
Has moistening and flushing effects: &Since a purification spray device is installed in front of the dust curtain, the coal dust captured by the dust curtain is moistened by the water droplets of the purification spray, and flushed to the tunnel floor, becoming Deposited coal dust that never floats
Guide trough dust curtain, dust curtain, cylindrical dust curtain, dust curtain manufacturer, dust curtain model dust soft curtain is made of high quality materials (wear rate parameter) , wear-resistant, soft and tough, especially in the northern winter, does not harden or crack, and has a long service life.
Using dust curtains to reduce wind flow on the mining working face. Coal dust mining operations are one of the production processes with the highest dust production in mine production. Especially in recent years, the application of top coal caving mining processes has resulted in the generation of coal dust in mining operations. The amount increases even more. How to reduce the coal dust concentration in the return air flow of the mining working face is a dust prevention task that countries around the world attach great importance to. We used dust curtains in the material transport tunnel of the mining working face, which effectively reduced the concentration of air flow coal dust in the return air tunnel of the mining working face.
The dust reduction principle of the dust curtain: The dust curtain has the following functions: It has blocking and filtering functions: Since the dust curtain is hung in the tunnel, the coal dust carried in the wind flow passes through the dust curtain. It is blocked and captured by the dust curtain, thereby reducing the concentration of coal dust in the air flow and purifying the air flow. It has moistening and flushing functions: Since a purification spray device is installed in front of the dust curtain, the coal dust captured by the dust curtain is moistened by the water droplets of the purification spray and flushed to the tunnel floor, becoming a sediment that never floats. coal dust.
The main reason for the dust generated at the outlet of the coal crusher is the blast effect of the coal crusher rotor and the induced wind caused by the large drop of the coal drop tube. The second reason is the air gap generated by the buffer deformation guide trough of the tail buffer roller. The induced wind generated by the machine and coal flow makes the guide chute positive pressure. If the guide trough is simply blocked, the positive pressure in the guide trough will inevitably increase further, and eventually it will eject from a weak link. If we only consider adding water spray at the outlet of the guide chute, the fine particles of dust can be suppressed, but the larger particles entrained by the induced wind cannot be eliminated.
