Ore pulp separator

Technical Field

The utility model belongs to the technical field of ore dressing equipment and specifically relates to an ore pulp separator.

Background

In the process flow of mine ore dressing, ore pulp separators are designed more, but the ore pulp cannot be distributed quite equally basically, particularly, the ore feeding distribution of a laminated high-frequency fine sieve is realized, and the number of equally distributed ore pulp pipelines is large. The reason is mainly that the multi-pipeline distribution cannot realize uniform distribution of all pipelines due to fluctuation of the pulp liquid level during distribution, and uneven distribution and distribution errors in the distribution process are caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an ore pulp separator is provided to make more accurate distribution of ore pulp one process next.

The utility model provides a technical scheme that its technical problem adopted is: the ore pulp separator comprises an inner ore collection box with a feeding hole at the top, wherein at least two overflow grooves are uniformly formed in the side wall of the inner ore collection box, and the extending direction of the overflow grooves is vertical.

The device further comprises at least two outer ore collecting boxes, wherein the outer ore collecting boxes and the overflow grooves are arranged in a one-to-one correspondence mode, and the bottom edge of the overflow groove is arranged above the opening of the ore collecting boxes.

Further, a ore discharging pipe is arranged at the bottom of the outer ore collecting tank.

Further, the number of the overflow tanks is 15.

Further, the ore feeding device comprises an ore feeding pipe, and an outlet of the ore feeding pipe is arranged above a feed inlet of the inner ore collecting box.

Further, the overflow groove is composed of semicircular holes at two ends and a rectangular groove between the semicircular holes.

Furthermore, the radius of the semicircular hole is 30mm, and the length of the rectangular groove is 550 mm.

Further, the inner wall surface of the inner ore collecting box is provided with a polyurethane coating.

Further, the inner wall surface of the outer ore collecting box is provided with a polyurethane coating.

The utility model has the advantages that: when the distribution device is in actual use, ore pulp to be distributed enters the inner ore collection box through the feed inlet, ore pulp flow is scattered in the inner ore collection box due to impact force, and the ore pulp can flow out through the overflow chutes which are uniformly distributed after the ore pulp gradually forms a liquid level. Because the overflow chutes have the same structure and are uniformly distributed, the ore pulp components passing through each overflow chute have small difference, so that the accurate distribution of the ore pulp is efficiently realized, and the distribution of multiple pipelines is also realized. The utility model discloses be particularly useful for among the ore feeding distribution technology.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a plan view of the present invention.

Figure 3 is a schematic view of an isopipe of the present invention.

Labeled as: the ore-feeding device comprises an ore feeding pipe 1, an inner ore collection box 2, an overflow groove 3, an outer ore collection box 4, an ore discharging pipe 5, an ore pulp liquid level 6, the end radius R of the overflow groove and the length H of an overflow groove rectangular groove.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

The ore pulp separator shown in fig. 1, 2 and 3 comprises an inner ore collecting box 2 with a feeding hole at the top, wherein at least two overflow chutes 3 are uniformly arranged on the side wall of the inner ore collecting box 2, and the extending direction of the overflow chutes 3 is vertical.

When the device is actually used, the distributed materials are mixed in solid and liquid, the particle size, specific gravity, slurry liquid level waves and the like of the solids are also influenced by factors such as volume and concentration of ore pulp, and the difficulty in equal distribution of multiple ore pulp parts is often high. In order to distribute the ore pulp uniformly, not only the fact that the solid matters are not deposited but also the number of distribution channels of the ore pulp distributor are considered, and the more the distribution channels are, the more the uniform distribution of the ore pulp is difficult to realize. The utility model discloses a design core is in order to overcome the ore pulp and to lead to the uneven problem of thick liquids distribution through the wave that produces when the feed inlet enters into interior collection ore deposit incasement. Therefore, the present application skillfully provides at least two overflow chutes 3 on the side wall of the inner ore collecting box 2, as shown in fig. 1 and fig. 2, such uniform distribution can reduce the problem of uneven distribution caused by the fluctuation of the liquid level of the ore slurry to the maximum extent, and can also quickly stabilize the fluctuation of the liquid level due to the existence of the overflow chutes 3. In actual use, the maximum particle size of solids in the distributed ore pulp is required to be less than or equal to 3mm, and the blockage of overflow narrow holes is avoided.

In order to collect and convey the slurry flowing out of the overflow launder 3 to the downstream area in a timely manner, such a solution is preferred: the device comprises at least two outer ore collecting boxes 4, wherein the outer ore collecting boxes 4 are arranged in one-to-one correspondence with overflow chutes 3, and the bottom edges of the overflow chutes 3 are arranged above the openings of the ore collecting boxes 4. Generally, it is preferable that the bottom of the outer collecting tank 4 is provided with a mineral dropping pipe 5 so as to carry out slurry transportation. In practical use, the number of the overflow chutes 3 is preferably 15, so as to achieve the effect of efficient and uniform distribution. In order to facilitate efficient transfer of the slurry into the inner collection box 2, such an arrangement is preferred: the device comprises an ore feeding pipe 1, wherein an outlet of the ore feeding pipe 1 is arranged above a feed inlet of an inner ore collecting box 2. The ore feeding pipe is arranged above the center of the inner ore collecting box to ensure that the inner ore collecting box 2 is evenly stressed to evenly distribute ore pulp to each overflow port.

In order to reduce the influence of the wave crest and the wave trough of the liquid level of the ore pulp and achieve better equal distribution of the ore pulp, the scheme is preferably as follows: the overflow groove 3 is composed of semicircular holes at two ends and a rectangular groove between the semicircular holes. As shown in FIG. 3, it is generally preferred that the radius of said semicircular opening, i.e., the radius R of the end of the isopipe, be 30mm, and that the length of the rectangular groove, i.e., the length H of the rectangular groove of the isopipe, be 550 mm.

In order to prolong the service life of the ore collecting box, the inner wall surface of the inner ore collecting box 2 is preferably provided with a polyurethane coating, and the inner wall surface of the outer ore collecting box 4 is preferably provided with a polyurethane coating.
