High performance conveyor-Buried Scraper Conveyor

     With regard to scraper conveyor, there are many types. Buried scraper conveyor belongs to it.The main features of buried scraper conveyor are that can be in a slant or vertical angle and operate together or individually. So it is universal. Buried scraper conveyor has a simple structure,light weight,small volume and good sealing. Also, it is easy to install or maintain. It not only can convey material in a horizontal angle,but also in a slant or vertical angle. What’s more, it can feed or discharge materials in many points. So its layout is very flexible. The working conditions can be changed markedly when it convey materials because the shell is enclosed.And then it can protect environment.

    We can solve the problem existed in medium plate which is made from steel through using ultra high molecular weight polyethylene. Thus, we can get plastic scraper conveyor. With regard to large-scale scraper conveyor, we can apply the method of steel-plastics compounding material. Using ultra high molecular weight polyethylene as lining, it can improve the abrasion resistance of large-scale scraper conveyor,and then prolong the service life, reduce the friction coefficient and bring down power consumption. It has great signific ance for large-scale scraper conveyor. Because of these features, buried scraper conveyor gets much attention of enterprises.

How to Design Buried Scraper Conveyor Scraper Chain to Minimize Trouble


 1. You should select the appropriate chain speed according to capacity and material properties, so that make the scraper chain run under reasonable load conditions. For the common material, scraper chainoperating speed range is generally 0.16 ~ 0.5m / s. You can choose a specific speed reference GB GB10596.1-89 standards and practical experience in the same industry units.

2. You should select the appropriate structure of scraper chain on the basis of delivery materials and transporting form. The selection principles are as following: in general, preferred forging chain, greater hardness of dust-like material should not be used bush roller chain, chain prone to floating material might as well use bush roller chain and double-plate chain. To ensure maximize the carrying capacity of scraper chain and avoid waste of energy and materials, you should be guaranteed under the condition that the scraper chain can bearing the maximum working load, choose the scraper chain closest to the required load and the maximum working load.

3.  Select the chain of materials Scraper chain material must ensure a certain strength. In the long time work, insufficient rigidity will force the scraper chain produce plastically deformed scraper chain elongation, and chain in installation has been tensioned, allowed elongated room is little. This will make scraper conveyor bear a powerful additional load, which will inevitably bring damage to the chain. In other words, scraper chain stiffness shortage will make scraper chain obvious distortion in use. The ideal steel material is manufacturing performance not less than 45, scraper chain have to overcome a lot of friction, bearing a lot of dynamic load and static load, so after the scraper chain manufacturing and post-weld, it should be carried out heat treatment, make it has high strength, toughness and wear resistance characteristic.

Troubleshooting of Buried Scraper Conveyor


Trouble
Reasons
Troubleshooting
Deviation of chain scraper
1.     The whole equipment installed improperly; casing straightness is too large; wheel axle deflection; head, tail wheel misalignment.
2.      Casing transmutation
3.      Tail wheel inclines after adjusting the take-up unit
1.Checked the  installation quality
2.Adjusting the casing
3. Readjustment
Chain scraper break
1.     Chain wear
2.     The conveyor Overloading operation result in the strength is not enough.
3.     Some hard material fallen into the closed trough and locked the scraper
1.Change chain
2.Eliminate long time overloading operation
3. After manual discharging the machine should feeding uniformly
Chain scraper bent result in break
1.     Casing are not straight
2.     The location of flange is offset then locks the scraper.
1.Checked the  installation quality
2.Dismantled original installation and install it again
During the operation of chain scraper, it gives out excessive noise
1.     Some hard material fallen into the closed trough
2.     Some chain with looseness or Inflexible faults
1.Clear debris
2.Change chain
Head wheel not fit in with chain scraper well
      1.     Head wheel chain inclines; Casing                 misalignment
      2.     The chain is wearing out after long time 
             operation
1.Rectify head wheel shaft
2.Change chain

Chain maintenance for Scraper Conveyor

All conveyor parts which may be subject to wear (wheels, chains, attachment, scraper bars) should be checked regularly for wear or damage. Chain contact surface are subject to normal wear, the extent of which is governed by chain quality, number of link movement, contact load and material handled. 



Wear in the contact areas reduces the chain thickness and thus has a direct relationship to service life. Ways to prolong the service life of the chain are as follow:

1.   Lubrication with lubrication oil, increases wear as it will form a grinding paste.
2.   Air and water washes or scrapers, which remove the material from the chain, drive and idling wheels reduce wear.
3.   Chain and attachments should be checked for damage following a conveyor overload.
4.  Chain replacement should always be combined with the replacement of all toothed wheels, or toothed rims, to ensure proper meshing of the chain.
