Description
Technical field
The utility model relates to the preparation equipment technical field, and particularly a kind of ball mill that prevents is to the ore deposit end device of falling the ore deposit.
Background technology
Ball mill is the important equipment in metallurgical mine ore dressing plant; Along with the demand of market to iron ore concentrate increases; The output of iron ore concentrate also increases thereupon; Increase when so just causing the unit treatment bench of ball mill, increase treating capacity and have only and increase raw ore amount that feeds ball mill and the milling medium steel ball amount that increases in the ball mill.After yet the raw ore amount increased with the steel ball amount in the ball mill, this two mixture plane just was higher than to the ore deposit sleeve, just appear at mineral-feeding pipe with to the phenomenon in ore deposit outside ball mill of the gap location between the sleeve end cap of ore deposit.Reason is because the axis of the axis of mineral-feeding pipe and ball mill conllinear not, thus form mineral-feeding pipe and ball mill is inhomogeneous to the gap between the end cap of ore deposit, and deviation is bigger; Though be provided with O-ring seal here; But the sealing function of O-ring seal is not obvious, causes taking place the serious phenomenon of falling the ore deposit, has both polluted working environment; Increase post personnel's labour intensity again, also increased production cost simultaneously.To this phenomenon of falling the ore deposit, the way of taking at present is below ball mill is given the ore deposit end cap, a big rectangle funnel to be set, and the mineral of pouring out fall into funnel, enter the pump hole with recirculated water through pipeline, through the slag stock pump it are fed permanent magnetic motor and sort.But because the mineral granularity that ball mill is poured out is excessive, be far longer than the granularity after ball mill grinds, behind the entering permanent magnetic motor under casing, part is deposited on the permanent magnetic motor under casing, and part is drained with mine tailing, causes waste.
Summary of the invention
The utility model provides a kind of ball mill that prevents to the ore deposit end device of falling the ore deposit, its objective is the fall ore deposit problem of thorough solution ball mill to the ore deposit end, improves working environment, reduces production costs, and boosts productivity.
The purpose of the utility model realizes through following technical proposals:
The utility model prevent that ball mill to the ore deposit end device of falling the ore deposit, comprising to ore deposit sleeve end cap, mineral-feeding pipe, it is characterized in that covering for the ore deposit socket end to be provided with the flange cover described; This flange cover socket-connects with described mineral-feeding pipe; Be provided with sealing gasket this flange cover and described giving between the sleeve end cap of ore deposit, be provided with the flange cover end cap of band centre bore, be provided with annular groove on every side at outer surface, the centre bore of this flange cover end cap at the other end of said flange cover; In this groove, be provided with sealing; On described flange cover end cap, be provided with the concentric gland of flange cover end cap therewith, at water accumulation pipe of outer surface socket of said mineral-feeding pipe, an end of this water accumulation pipe is provided with the water accumulation pipe end cap; The inner surface of the other end evenly is provided with one group of brace rod; Top at said water accumulation pipe is provided with water filling port, and the centre bore that described water accumulation pipe passes said flange cover end cap inserts in the described flange cover, and described water accumulation pipe, flange cover and described giving form the ponding chamber between the sleeve end cap of ore deposit.
Described flange cover by with the said canned paragraph of fixing and be connected for ore deposit sleeve end cap; One end is the section of being flexible coupling that is connected of canned paragraph therewith; The free section that is connected of the other end of the section of being flexible coupling therewith; The one group of transmission torque mechanism that is located at the outer surface of said canned paragraph is formed, and the other end of said free section fixes with described flange cover end cap and is connected.
Described transmission torque mechanism is by the torque pin that is located at said free section outer surface; Be located at the outer surface of said canned paragraph and the transmission torque plate of torque pin corresponding section therewith; Be located at this conduction hole of transmitting on the torque plate and form, this conduction hole and described torque pin socket-connect.
Said one group of quantity of transmitting torque mechanism is 2-6.
The described section of being flexible coupling is a rubber sleeve.
Describedly be sealed into the packing linear sealing.
The ball mill that prevents of the utility model to the advantage of the ore deposit end device of falling the ore deposit is:
1, adopt the recirculated water top towards method; Be that recirculated water gets in the ponding chamber through the water filling port of water accumulation pipe; Because ball mill inside is atmospheric pressure state, and the pressure of recirculated water is 0.4Mpa, so in the ponding chamber, also formed 0.4Mpa hydraulic pressure; Therefore the inner mineral of ball mill just can not be poured out to the fit clearance between the sleeve end cap of ore deposit from mineral-feeding pipe and ball mill, have thoroughly solved ball mill and have fallen the problem in ore deposit to the ore deposit end;
2, adopted the flange cover that constitutes by canned paragraph, the section of being flexible coupling and free section; Compensate because ball mill axis and the mineral-feeding pipe axis eccentric throw that produces of conllinear not through free-ended swing, avoid flange to overlap because of the damage that causes after the long-term work or the damage of mineral-feeding pipe;
3, because the section of being flexible coupling is a rubber sleeve; Its tube wall is thinner, and it is relatively poor to be turned round ability, carries out the damage that canned paragraph causes to the moment of torsion transmission of free section for a long time for preventing rubber sleeve; Evenly be provided with 6 at flange cover outer surface and transmit torque mechanism; Transmitting between torque plate and the torque pin is to slide relatively, can satisfy the demand that free section freely swings, and can guarantee the transmission of moment of torsion again.Prolonged the service life of flange cover.
The utility model has improved working environment, has reduced working strength of workers, reduced the loss of mineral, has thoroughly solved ball mill and has fallen the problem in ore deposit to the ore deposit end, and economic benefit is obvious.
