Yesterday the Japanese newspaper reported
,
Five merchants climbed to the fourth and fifth floors of the square and threatened to jump off the building. Firefighters and medical staff came to the scene to rescue them. Several people came to the rescue with friends and square managers. Finally, he was persuaded to give up.
Yesterday afternoon, the New Express reporter came to Best Home Furnishing Plaza again. The reporter saw at the scene that the unidentified man guarding the entrance and exit of the square two days ago was gone. The entrance and exit of the square had returned to normal, and people could enter and exit normally. People around the square There were still twenty or thirty men wearing black shirts and red armbands walking around, and police officers sent by the public security department remained at the scene to maintain order.
Improvement of the sealing form of the guide trough of the belt conveyor
>1. Project proposal background
>In the belt transportation system, the original design of the guide trough adopts the single-layer side plate bottom closing method
> And the rubber seal, the guide trough sealing tape wears out very quickly during use, and it only takes about two months
>The rubber must be replaced. The entire factory has a lot of work to replace the guide trough sealing rubber
> It accounts for about 1/2 of the maintenance work of fuel transportation equipment, and thus causes the following impacts:
>. Serious powder leakage on site, resulting in a passive situation of civilized production of equipment and sites
>. On-site The dust is large, which affects the operation of inspection equipment and cannot detect equipment defects in time. Maintenance cannot ensure the quality of maintenance and may cause dust deflagration during maintenance, which cannot ensure safety.
> It reduces the occupation of human resources, causing the team to fail to perform normal maintenance work. Follow up and induce other equipment problems.
>2. Problems with the existing sealing form of the guide trough
>According to the technical requirements, the distance between the bottom end of the lower end of the side plate of the guide trough and the belt is controlled, but the actual situation on site is not like this. . During the installation process of the original guide trough, it was not installed in place according to the design requirements. The distance between the bottom end of the lower end of the side plate of the guide trough and the belt was too large. There were various spacings, etc. When the belt was running, a large amount of coal flowed. Due to The distance between the bottom end of the lower opening of the side plate of the guide trough and the belt is too large. The thick coal flow at the boundary of the belt directly acts on the sealing rubber, which produces a large impact force and lateral pressure on the sealing rubber of the guide trough and separates the coal pipe. When working, the coal flow in the pipe falls to the surface of the tape with a great impact force, which exerts a great lateral pressure on the sealing rubber, causing the coal flow to wash away the sealing rubber and causing the rubber to wear and become thinner. This process is relatively long. According to the development The trend is about .3 months,
>3. Solutions to the problem
>Solution ideas: Take measures to avoid direct flushing of the sealing rubber by the coal flow as much as possible or reduce the flushing force to extend the initial In the wear stage, one is to reduce the distance between the bottom end of the lower end of the side plate of the guide chute and the belt, and control it within & to reduce the impact and lateral pressure of the coal flow on the sealing rubber; the other is to increase the pressure at the initial coal falling point. Install the inserting plate to control the thickness of the coal seam on the belt, feed coal evenly, and reduce the thickness of the coal flow on both sides of the belt at the guide trough.
>. Specific measures:
> Weld the wear-resistant plate at the bottom end of the existing guide trough side plate, and control the distance between the bottom end of the welded side plate and the tape gap to effectively isolate or reduce The flushing power of coal flow.
>Install the lower insert plate at the starting point of coal feeding (in front of the car coal ditch coal feeder or the train coal double coal feeder) to control the thickness of the incoming coal, feed the coal evenly, and lower both sides of the belt at the guide chute. The coal flow thickness.
>Suggestion: Optimize the operation mode and try not to overload the belt, especially the belts after the #belt bucket wheel machine. If necessary, please operate for further control and do not overload the belt.
>4. Conclusion
>When the small method is running, improve one, conduct experiments, and observe the effect.
