Abstract
The utility model provides an ore discharge covers for ball mill, including a siphonozooid, it has a discharge gate to open on the pipe wall of siphonozooid, the both ends of siphonozooid all are equipped with the baffle, the middle part of baffle is equipped with circular through -hole, the mid -mounting of baffle has circular rubber circle, the aperture of rubber circle is less than the aperture of baffle through -hole, the inner peripheral surface of rubber circle is equipped with the round recess, sealing grease is equipped with in the recess. With the ore discharge envelope of hood of above -mentioned structure dress on row's material portion hollow shaft of ball mill, through install on the baffle the rubber circle with arrange the hollow shaft contact cooperation of material portion because the inner peripheral surface of rubber circle is equipped with the round recess, be equipped with sealing grease in the recess, just so can guarantee the ore discharge cover and arrange difficult wearing and tearing the in position that material portion hollow shaft contacted, strengthened the leakproofness of ore discharge cover.
Description
Technical field
The utility model relates to a kind of ore discharge cover of parts, particularly a kind of ball mill for industry centric drive ball grinding machines such as mine, metallurgy, electric power, building materials.
Background technology
Ball mill is generally by System's composition such as feed portion, bearing portion, feeder, barrel, discharging portion, discharge part, transmission devices, barrel is long cylinder, cylinder is built with abrasive body, cylindrical shell is steel plate manufacture, abrasion-proof backing block and cylindrical shell is had to fix, abrasive body is generally steel ball, and presses in different-diameter and certain proportion loading cylinder, and abrasive body also can use steel section.Material enters in cylindrical shell by feeding of ball mill portion charging aperture, when ball mill barrel rotates time, abrasive body is due to inertia and centrifugal action, the effect of frictional force, make it be attached on shell liner to be taken away by cylindrical shell, in time being brought to certain height, left due to the Action of Gravity Field of itself, the abrasive body of whereabouts as projectile by the material in cylindrical shell to smashing.Simultaneously in grinding machine rotation process, the mutual sliding motion of abrasive media also produces abrasive action to material, and the material after grinding is discharged by discharge part tubular journal.Be set with an ore discharge cover at the outer peripheral face of the tubular journal of discharge part, prevent the material splashes of discharging, the material after grinding enters ore discharge cover from discharge part tubular journal, then is discharged by the discharging opening of ore discharge cover.
Because the cylindrical shell of discharge part hollow shaft in company with ball mill rotates together, ore discharge cover is then hard-wired, so the position that ore discharge cover contacts with discharge part hollow shaft is easy to be worn because rub for a long time, thus the sealing affected between ore discharge cover and discharge part hollow shaft, some material will be caused like this to overflow from fray, not only waste resource, pollute work-yard again.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of ball mill ore discharge cover that the position contacted with discharge part hollow shaft is not easily worn, sealing is strong.
For solving upper technical problem, the technical solution of the utility model is: a kind of ball mill ore discharge cover, comprise a tubular body, the tube wall of described tubular body has a discharging opening, the two ends of described tubular body are equipped with baffle plate, and the middle part of described baffle plate is provided with manhole, the middle part of described baffle plate is provided with round rubber circle, the aperture of described rubber ring is less than the aperture of described baffle plate through hole, and the inner peripheral surface of described rubber ring is provided with a circle groove, in described groove, stop-leak compound is housed.
The ore discharge enclosure of said structure is contained in the discharge part hollow shaft of ball mill, to contact with discharge part hollow shaft coordinate by being arranged on rubber ring on baffle plate, inner peripheral surface due to rubber ring is provided with a circle groove, in described groove, stop-leak compound is housed, so just can ensure that the position that ore discharge cover contacts with discharge part hollow shaft is not easily worn, enhance the sealing of ore discharge cover.
Preferably, described rubber ring is arranged on the outside of described baffle plate.
In one embodiment, described rubber ring is arranged on baffle plate by bolt.
Further, described tubular body combines installation by upper tube wall and lower tube wall and forms, and described discharging opening is positioned at lower tube wall.This knockdown structure is conducive to installation and the maintenance of ore discharge cover.
Preferably, the width of described discharging opening equals the length of tubular body.Enough width can ensure the smooth and easy of discharge.
Preferably, described tubular body and baffle plate all adopt steel plate to make.

Detailed description of the invention
As shown in Figures 1 to 3, preferred embodiment of the present utility model is: a kind of ball mill ore discharge cover, comprise a tubular body 1, described tubular body 1 combines installation by upper tube wall 11 and lower tube wall 12 and forms, the lower tube wall 12 of described tubular body 1 has a discharging opening 2, the width of described discharging opening 2 equals the length of tubular body 1; The two ends of described tubular body 1 are equipped with baffle plate 3, described tubular body 1 and baffle plate 2 all adopt steel plate to make, the middle part of described baffle plate 2 is provided with manhole, the middle part of described baffle plate 2 is provided with round rubber circle 4, described rubber ring 4 is arranged on the outside of baffle plate 2 by bolt 5, the aperture of described rubber ring 4 is less than the aperture of described baffle plate 2 through hole, and the inner peripheral surface of described rubber ring 4 is provided with a circle groove, in described groove, stop-leak compound is housed.
As shown in Figure 3, the ore discharge enclosure of said structure is contained in the discharge part hollow shaft 6 of ball mill, to contact with discharge part hollow shaft 6 coordinate by being arranged on rubber ring 4 on baffle plate 2, inner peripheral surface due to rubber ring 4 is provided with a circle groove, in described groove, stop-leak compound is housed, so just can ensure that the position that ore discharge cover contacts with discharging portion hollow shaft 6 is not easily worn, enhance the sealing of ore discharge cover.
The improvements of the utility model relative to prior art are understood more easily in order to allow those of ordinary skill in the art, accompanying drawings more of the present utility model and description are simplified, and for the sake of clarity, present specification is omitted some other elements, and those of ordinary skill in the art it is to be appreciated that these abridged elements also can form content of the present utility model.
