Method for preventing longitudinal tear of anticorrosive tape

一分彩Method for preventing longitudinal tear of anticorrosive tape

Polyethylene tapes have very important applications in daily life and industrial production, as well as in various industries.The polyethylene tapes of polyethylene tape conveyors do not undergo longitudinal tearing during normal operation. Or external sharp objects, such as steel plates, iron blocks, I-beams, anchors, large vermiculite, etc., may cause polyethylene tapes to be scratched and torn when severe. The deviation of polyethylene tape causes polyethylene tape to tear. Generally, only the edge of polyethylene tape is torn, and it will not appear on the inside of polyethylene tape. It is easier to prevent the polyethylene tape from drifting. Install it according to requirements during installation. Normal use will not cause serious polyethylene tape tearing accidents.

 

1. Foreign body source.

源头 The main sources of foreign matter in the coal transportation system are:

一分彩① Due to the carelessness of the construction personnel, the hard objects such as the brazing rod and I-beam used in the construction are left behind, near the upper mouth of the coal bunker.

② The coal feeding equipment and coal blocking device in the coal flow transportation system are not firmly connected during processing, causing some parts to fall off.

③ During the coal mining process, the anchor rod was not fully recovered, and the polyethylene tape conveyor entered the coal chute and coal bunker. It stuck at the coal feeding port and poked into the polyethylene tape. Eyes and coal bunkers fell off large chunks of vermiculite after being damaged by falling coal.

一分彩2. Measures to prevent foreign matter from entering the coal flow system of the polyethylene belt conveyor.

3. It is strictly forbidden to leave hard objects near the coal chute and the upper mouth of the coal bunker. During the construction of the coal flow system, especially after the construction of the coal chute and the coal bunker, it shall be completely cleaned. It is strictly forbidden to leave objects that may cause scratches or tears of polyethylene tape near the coal chute and the upper mouth of the coal bunker.

一分彩4. Improve the construction technology of the coal chute. In the construction of coal gangue and coal bunkers, the use of slope protection rails or laying of steel plates should be avoided to strengthen the lower necking of coal gangues and coal bunkers. The shrinkage of the coal chute and coal bunker should be in the form of hyperbola, and high-strength steel sand concrete is used for pouring. The support of the coal chute and coal bunker shall be supported by long anchor rods, and the length shall not be less than 2m, to prevent the anchor wall from falling into the coal stream after the coal wall is impacted by the coal flow, which may cause the polyethylene tape to be scratched or torn. In particular, the coal chute, the upper mouth of the coal bunker, and the vicinity of the coal feeding point should be closed. Non-workers should never touch the polyethylene tape conveyor to prevent foreign objects from falling into the polyethylene tape.

5. During coal mining, the anchor must be recovered. It is strictly forbidden to enter the polyethylene belt conveyor. It is generally not allowed to use polyethylene tape conveyors to transport I-beams, anchors and other objects. If it is really necessary, special measures must be formulated.

 

6. Change the way of falling coal

一分彩The polyethylene belt conveying and transportation system is a one-stop transportation. Coal from the working face to the bottom of the coal bunker generally needs to be re-transported by several polyethylene belt conveyors, and in the middle it also passes through the coal slipper and coal bunker in the mining area. Coal stream should be avoided from directly entering the coal chute and coal bunker in the mining area. Landslides shall be constructed in the coal chute and coal bunker in the mining area.

一分彩7. Install iron removing device at appropriate place

一分彩The polyethylene belt transportation and transportation system is a one-stop transportation.Generally, the coal from the working face to the bottom of the coal bunker must be re-transported by several polyethylene belt conveyors. The iron removal device is installed at the part, which can effectively clean out the iron blocks that cause the polyethylene tape to tear in time. It can be considered to install iron removal devices at the appropriate parts of the reloader, down-trunk polyethylene belt conveyor head, coal chute landslide, reprint, polyethylene belt lane polyethylene belt conveyor. Remove the iron before proceeding to the next transport link. High temperature anticorrosive tape price
