Abstract
The utility model belongs to coal washing and screening equipment, in particular to a movable screen gangue-removing machine, solving the problems that in the existing gangue-removing roller of the movable screen gangue-removing machine, the bearing is easily damaged, the chain is easy to fall and the like. The movable screen gangue-removing machine comprises a gangue-removing roller; the transmission of the gangue-removing roller adopts a circular ring chain for transmission; the circular ring chain is provided with a chain tensioning mechanism which comprises a tensioning wheel; and the matched positions of the shaft end of the gangue-removing roller, a bearing seat and a bearing end cover adopt a rotating grid for a shaft to enclose and are matched with closed loose ribs for sealing. The tensioning wheel is connected with a sliding frame; a fixed lead screw is fixed above the sliding frame; an adjusting nut matched with the lead screw is fixed on a movable screen gangue-removing machine body above water; and two sides of the tensioning wheel are provided with limiting blocks. The movable screen gangue-removing machine reduces the probability of damaging the bearing, greatly reduces the possibility that the gangue-removing roller can not rotate due to sealing failure of the sealing rings, reduces the condition that the chain is released or clamped under the conditions of water and vibration, and improves the fault-free working time.
Description
Technical field
The utility model belongs to coal washing equipment, is specifically related to a kind of moving sieve discharge refuse machine.
Background technology
Moving sieve discharge refuse machine is mainly used in the primary election before coal goes into to wash or makees the lump coal washing appliance in coal preparation plant.It both can be used as the size sorting equipment in the washed coal technology, and the pre-processing system that also can be used as block raw coal carries out raw coal and selects cash, steam coal separation or handle rash.The discharge refuse roller arrangement is being undertaken the critical function of moving sieve discharge refuse machine raw coal discharge refuse, it together vibrate with sifting bed and long period of soaking in black water, working environment is very abominable.This just requires this modular construction should satisfy the sealing at floating bearing place, ensures the reliability of chain drive again.
Existing moving sieve discharge refuse machine discharge refuse roller is limited by steric requirements, and the bearing installation position is narrow and small, and wholely works in black water, and sealing problem is most important.Original structure adopts skeleton rotary shaft lip seal, and except that bulky, outside taking up room, its service life and security reliability are also not fully up to expectations, usually occurs the phenomenon of sealing premature failure, damage of bearings in actual applications.
The circle chain of mine transmission is adopted in the transmission of discharge refuse roller in addition, and whether the tensioning of chain is crucial part reliably.Because chain is in the black water and together shakes with sifting bed, this has brought difficulty with regard to the design of giving chain stretching device.Because structural configuration is unreasonable, in water, be difficult to adjust easily the tensioning degree of chain, cause chain under current and vibration double influence, fall chain, the chain jamming phenomenon happens occasionally, and the fault rate of complete machine is risen, the efficiency of separation descends.
As mentioned above, existing discharge refuse roller exists bearing seal unreliable, and the bearing rapid wear is subjected to sifting bed vibration effect chain to come off shortcomings such as chain tension inconvenience easily in the chain drive.
Summary of the invention
There are problems such as bearing rapid wear, chain easily come off in the utility model for the discharge refuse roller that solves moving sieve discharge refuse machine in the prior art.
The utility model adopts following technical scheme to realize:
Moving sieve discharge refuse machine, it comprises the discharge refuse roller, the round-link chain transmission is adopted in the transmission of discharge refuse roller, establish chain tensioning mechanism on the round-link chain, chain tensioning mechanism comprises regulating wheel, and the cooperation place that it is characterized in that described discharge refuse roll shaft end and bearing block and bearing (ball) cover is adopted axle to enclose with the rotation lattice and is equipped with the enclosed loose rib and seals.
Regulating wheel is connected in travelling carriage, and travelling carriage upper fixed screw mandrel, the adjusting nut that cooperates with screw mandrel are fixed on the moving sieve discharge refuse machine body waterborne, and the regulating wheel both sides are provided with limited block.
The utlity model has following beneficial effect: the improvement by to China's existing moving sieve discharge refuse machine discharge refuse roller sealing, improved the reliability of black water middle (center) bearing sealing.Reduced the probability of damage of bearings, reduced greatly because the possibility that the sealing ring seal failure causes the discharge refuse roller not rotate.
In addition, improved chain stretching device, can regulate the tensioning degree of discharge refuse roller driving-chain easily and effectively, reduce chain in water and the condition of the vibration situation of taking off chain, chain jamming, improve the time between failures of complete machine, the coal separation discharge refuse effect of giving full play to moving sieve discharge refuse machine is significant.

Fig. 2 is the structural representation of chain tensioning mechanism of the present utility model
Fig. 3 is the discharge refuse roll structure schematic diagram of existing moving sieve discharge refuse machine
Fig. 4 is the structural representation of the chain tensioning mechanism of existing moving sieve discharge refuse machine
Among the figure: 1-discharge refuse roller, the 2-bearing (ball) cover, the 3-bearing block, the 4-axle encloses with the rotation lattice, 5-enclosed loose rib, the 6-round-link chain, 7-adjusting nut, 8-screw mandrel, 9-travelling carriage, 10-regulating wheel, the 11-limited block, 12-body, 13-link-supporting plate, the skeleton rotary shaft lip seal of 14-.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
Moving sieve discharge refuse machine, it comprises discharge refuse roller 1, the round-link chain transmission is adopted in the transmission of discharge refuse roller, establish chain tensioning mechanism on the round-link chain, chain tensioning mechanism comprises regulating wheel 10, and the cooperation place that it is characterized in that described discharge refuse roller 1 axle head and bearing block 3 and bearing (ball) cover 2 is adopted axle to enclose 4 with the rotation lattice and is equipped with enclosed loose rib 5 and seals.The skeleton rotary shaft lip seal that original discharge refuse roller two-end structure is adopted is replaced by dual axis and is enclosed with the rotation lattice and be equipped with the enclosed loose rib again, this will effectively improve the sealing effectiveness of discharge refuse roller in black water, reduce because bearing seal damages the possibility that causes the discharge refuse roller not rotate.
Regulating wheel 10 is connected in travelling carriage 9, and travelling carriage 9 upper fixed screw mandrels 8, the adjusting nut 7 that cooperates with screw mandrel 8 are fixed on the moving sieve discharge refuse machine body 12 waterborne, and regulating wheel 10 both sides are provided with limited block 11.Regulating wheel under water, the tensioning regulator site on the water, by function element such as leading screw, adjusting nut, travelling carriage, limited blocks, satisfied the requirement of " conveniently, adjusting the chain tension degree flexibly, in good time, reliably ", and versions such as chain guard, link-supporting plate have been adopted, solve the phenomenon of easily falling chain, chain jamming in the transmission of discharge refuse roller effectively, strengthened chaindriven reliability.
