Description
Technical field
The utility model relates to technical field of coal mine, and in particular to a kind of cutter chain device.
Background technique
Coal is the main energy sources in China, accounts for 70% or more in disposable energy-consuming, at quite long one section
In phase, coal will not change as the status of main energy sources.
For thermal coal selective ratio in 2010 less than 800,000,000 tons, selective ratio is about 35%.With the development of national economy, Ren Minsheng
Increasingly improvement living, scientific and technical is constantly progressive, and energy-saving and emission-reduction are carried forward vigorously, and utilizes increasingly to the clean and effective of coal
It is taken seriously, " the clean coal technology plan " that China is carrying out then is come into being.Coal preparation is undoubtedly clean
The basis of clean coal technology, it can fundamentally improve and improve Coal Quality, reduce pollution brought by coal burning, reduce
Energy consumption improves transport power, increases the performance of enterprises, current driving force coal selective ratio is about 14.7 hundred million tons, and selective ratio has reached 53.5%.
Heavy media coal separation method is tested since mid-term the 1950s in China.Since heavy media coal separation is with many excellent
Point, especially its sharpness of separation height, selected particle size range are again wide, so its application range in coal preparation technique is very wide
It is general.In recent years, with the further development of coal market economy, the requirement of environment and user to Coal Quality is higher and higher, essence
The superiority of degree sink float is more and more obvious, and most of newly-built or reconstruction coal preparation plant all uses part dense medium or full sink float
Coal.So far, the selected specific gravity of the heavy media coal separation method in China will be stepped up to 70% or more.
Currently, most of hm coal preparation plants are sorted using Separator of heavy medium shallow slot, equipment sorting is accurate
Degree is high.Since the lifting wheel of heavy product is moved in the slot bottom of Separator of heavy medium shallow slot, in assorting room in suspension
Material can not be disturbed, and possible deviation (E) can reach 0.02~0.03；It is wide to sort particle size range, since dense media shallow slot sorts
The sorting groove face of machine can be made openr, and sorting upper size boundary is 200~300mm, and lower limit is 6~8mm；Treating capacity
Greatly, such as the groove width of sorting groove is the sorting machine of 1m, and treating capacity is about 100t/h；And production process is easy to automate.
But in the maintenance of the repair and maintenance of Separator of heavy medium shallow slot, frequently refer to the replacement of driving chain.Under normal conditions,
Import chain every half a year, replacement was primary, and domestic chain every three months replacement is primary, and chain is first cut into several by replacement chain needs
Section is attached again.
The method of existing shallow slot chain cutter chain is：After side chain and chain-plate is removed, by chain both ends suspending apparatus
It props, after manually being fixed with hand, another person strikes pin shaft one end with sledgehammer, by the hammering of sledgehammer that pin shaft is another from chain
Outer side is got, so that chain is truncated.The method large labor intensity of existing shallow slot chain cutter chain replaces low efficiency, same
Time can only strike a pin shaft, so that two pin shafts move back the amount of unloading imbalance, pin shaft exits difficulty, and is directly hit with sledgehammer
Pin roll end face is beaten, pin shaft is easy to cause to damage, and is possible to generation splash and operator is damaged, security system number
It is low.
