Abstract
The invention relates to a sundries removing device for a throat of a mill. The sundries removing device is arranged below an ore pulp discharge hole of the mill and is composed of filter nets which are arranged at the upper end of a square cone-shaped or circle cone-shaped hopper in a fit manner, and an outlet at the lower end of the square cone-shaped or circle cone-shaped hopper is connected with a lower process pipeline. Square side length or excircle diameter of each filter net which is arranged at the upper end of the square cone-shaped or circle cone-shaped hopper in the fit manner is 3-4 times of the diameter of the ore pulp discharge hole of the mill, so that enough filtering area is guaranteed; and pore diameter of each filter net is (4-6)*(4-6)mm. The sundries removing device for the throat of the mill disclosed by the invention can eliminate sundries mixed into ore during underground mine production such as a detonating tube, improve purity of the ore pulp, reduce influence to processing equipment and pipelines, improve production process effect and promote improvement of technological technical indexes and economic benefit; no power device is required, and no operating cost is increased; and the sundries removing device is simple in structure, low in investment cost and small in maintenance workload, and a scrapped filter net is more convenient to replace.
Description
Technical field
The present invention relates to a kind of grinding machine gape and get rid of incidental device.
Background technology
Rod mill, ball mill be the ore dressing plant, cement plant in mine etc. to the main production equipments of ore deposit rock dust breakdown mill, be positioned at the leading portion of ore-dressing technique; The granularity of the ore pulp of grinding machine discharging, the quality index such as purity play material impact to the hypomere production technology.And the tcrude ore that mine down-hole is produced, inevitably sneak into certain foreign material, enter into grinding machine with tcrude ore and be blended into ore pulp, particularly in recent years, the nonel tube that state compulsion is carried out plays technology, make especially the detonator chip of sneaking in the ore after a large amount of explosions are scraped, the foreign material such as detonator chip enter into mineral processing circuit with ore pulp, can cause the obstruction to the ore-dressing technique pipeline, to spiral concentrator, the obstruction of the overcurrent classification faces such as spiral chute, disturb the valuable mineral classification of shaking table face to sort, greatly affected the patency of production procedure and the normal production of ore dressing; After must getting rid of first foreign material, the ore pulp of grinding machine discharging inputs again the hypomere production technology.The patent No.: 201020186672 utility model discloses a kind of ore pulp pipeline conveying device that can remove foreign material in the ore pulp, be provided with the separation chute of helical annular at ore pulp chute, this separation chute is high-end to communicate with overfall, the lower end communicates with the concentration basin feeding mouth, utilize centrifugal principle, the foreign material in the cleaning ore pulp chute; But the one, the ore pulp foreign material bonding of separating chute is cleared up unclean; The 2nd, under centrifugal action, in separating sundries, unavoidably take useful ore pulp out of, cause waste and contaminated environment.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of grinding machine gape and gets rid of incidental device, utilizes the fluid deadweight of ore pulp to realize filtering the eliminating foreign material, and unpowered device does not increase operating cost.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of grinding machine gape is got rid of incidental device, be installed in the mill slurries floss hole below, the grinding machine gape is got rid of incidental device and is comprised of the screen pack on the taper of the cooperation side of being installed in or the taper funnel, and the lower end outlet of square taper or taper funnel is connected with the hypomere process pipe.Described and square taper or taper funnel upper end cooperates the square length of side of screen pack of installation or 3-4 times of diameter that outer garden diameter equals the mill slurries floss hole, and guaranteeing has enough filter areas; The aperture of screen pack is (4-6) * (4-6) mm.The foreign material that the grinding machine operative employee generally is filled on 30 minutes labor cleanings get rid of screen pack.
The invention has the beneficial effects as follows:
1, the present invention has broken mine ore dressing production rod mill, ore pulp discharged by ball mill and lower segment process links, the way that sealing traditionally links, separated in mill slurries outlet and lower segment process connecting piece road, add the ore pulp miscellaneous object-removing equipment, the production of removing mine down-hole is blended into the foreign material such as detonator in the ore, improves ore pulp purity, reduces the impact on process equipment, pipeline, improve the production technology effect, promote the raising of technical indicator and economic benefit.
2, unpowered device utilizes the fluid deadweight of ore pulp to realize filtering the eliminating foreign material, does not increase operating cost.
3, apparatus structure is simple, Meteorological is low; The steel construction screen pack is sturdy and durable, and maintenance workload is minimum, and the filter screen replacement of scrapping is convenient.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of screen pack.
The specific embodiment
Embodiment 1As shown in Figure 1, 2: a kind of grinding machine gape get rid of incidental device be installed in mill slurries floss hole 1 below, grinding machine gape eliminating incidental device is comprised of the screen pack 2 of the cooperation side of being installed in taper 3 upper ends, and the lower end outlet of square conical hopper 3 is connected with the hypomere process pipe.Described and square conical hopper 3 upper ends cooperate the square length of side of the screen pack 2 of installing to equal 3 times of diameter of mill slurries floss hole 1, and guaranteeing has enough filter areas; The aperture of screen pack 2 is 5 * 5 mm.The foreign material that the grinding machine operative employee generally is filled on 30 minutes labor cleanings get rid of screen pack.
The present invention has broken mine ore dressing and has produced rod mill, ball mill discharge ore pulp and the binding of lower segment process, the way that sealing traditionally links, separated in mill slurries outlet and lower segment process connecting piece road, add the ore pulp miscellaneous object-removing equipment, the production of removing mine down-hole is blended into the foreign material such as detonator in the ore, improves ore pulp purity, reduces the impact on process equipment, pipeline, improve the production technology effect, promote the raising of technical indicator and economic benefit.The filtration that mainly is adapted to the ore pulp outlet foreign material such as mine rod mill, ball mill is removed.
Embodiment 2As shown in Figure 1, 2: a kind of grinding machine gape get rid of incidental device be installed in mill slurries floss hole 1 below, the grinding machine gape is got rid of incidental device and is comprised of the screen pack 2 that cooperation is installed in taper funnel 3 upper ends, and the lower end outlet of taper funnel 3 is connected with the hypomere process pipe.The described outer garden diameter that cooperates the screen pack 2 of installing with taper funnel 3 upper ends equals 4 times of diameter of mill slurries floss hole 1, and guaranteeing has enough filter areas; The aperture of screen pack 2 is 4 * 6 mm.The foreign material that the grinding machine operative employee generally is filled on 30 minutes labor cleanings get rid of screen pack.
