Abstract
The utility model relates to a discharge and screening device of a wind power discharge ball mill. The discharge and screening device of the ball mill comprises a screen, a feeding pipe and a vertical sleeve; the screen is arranged in the sleeve in a matching way and forms a certain angle a with the horizontal direction; the feeding pipe is correspondingly arranged on the lowest end of the screen, and is kept consistent with the inclination direction of the screen; the feeding pipe is communicated to the inner cavity of the sleeve above the screen; and the upper port of the sleeve is butted to the discharge pipe end of the ball mill, and the lower port of the sleeve is butted to an air duct of the ball mill. The discharge and screening device of the ball mill has the positive and beneficial effects that worn small-particle medium can be conveniently and timely screened, a pipeline is prevented from being blocked, follow-up winnowing equipment is prevented from being eroded and damaged, and the service life is prolonged; and the installation and the use are convenient, the maintenance and the replacement are easy, the use cost is low, and the generalization and the popularization are easy.
Description
Technical field
The utility model relates to abrasive dust equipment, is specifically related to a kind of wind-force discharge ball mill discharging screening plant.
Background technology
Ball mill is applicable to the various ores of grinding and other material, is widely used in ore dressing, industries such as building materials and chemical industry.Wind-force discharge ball mill is one of important ball mill, its operation principle is as follows: material enters ball mill from material inlet, mill be situated between to material impact with grind after, material moves to outlet gradually from the import of grinding machine, the port of export is connected with airduct, the separator of in system, connecting, powder concentrator, the import of deduster and blower fan, when the wind-force discharge comes into operation, the relative lower negative pressure that is in the ball mill mill chamber, broken back by levigate material along with wind-force enters pipe-line system from discharging opening, by powder concentrator will be thicker particle separation after send into the ball mill import again, the material that has ground then separate to be reclaimed by separator.Wind-force discharge ball mill is in the long-term operation process, and the mill of mill chamber Jie (medium ball) can constantly be worn and torn, and until becoming tiny particle, discharges mill chamber with other material in small, broken bits with wind-force, enters pipe-line system.Yet because the grinding media metric density is bigger, the one side that enters pipe-line system can deposit at the turning, until the blocking pipe system, also can cause erosion, damage to pipeline and follow-up equipment such as pneumatic separator on the other hand, and then shortened its life-span, cause unnecessary loss.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of wind-force discharge ball mill discharging screening plant that sieves out mill Jie particle of wearing and tearing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of ball mill discharging screening plant, comprise screen cloth, passage and the sleeve pipe that vertically is provided with, be installed in the described sleeve pipe to described screen cloth coupling, and screen cloth and horizontal direction а in a certain angle is provided with, described passage is arranged on the least significant end of described screen cloth accordingly, and be consistent with the screen cloth incline direction, this passage is communicated in the cannula cavity of screen cloth top; The upper port of described sleeve pipe is docked at the discharging mouth of pipe of ball mill, and its lower port butts up against the ball mill airduct.
Above-mentioned screen cloth and horizontal direction angle а satisfy following condition: 15 °≤а≤45 °.
The upper port of above-mentioned sleeve pipe is docked at the discharging mouth of pipe of ball mill by ring flange, and its lower port butts up against the ball mill airduct by ring flange.
Be installed on to above-mentioned screen cloth coupling on the oval flange on the internal surface of sleeve pipe.
The discharging opening end of above-mentioned passage is for being bent downwardly transitional pipe segment.
The place also can be provided with the air intake sideboard that is complementary at above-mentioned passage discharging opening.
Under described passage discharging opening, also be provided with collection container.
Described screen cloth is 10～150 mesh sieves.
The utlity model has actively useful effect:
1. can in time sift out the granule medium of wearing and tearing, prevent blocking pipe, avoid follow-up pneumatic separator is caused erosion, damage, prolong its service life;
2. easy to install, be easy to safeguard and change, simple in structure, cheap for manufacturing cost, be easy to popularize.
