Description

Ore pulp evenly divides ore deposit case

Technical Field

The utility model relates to the technical field of mining equipment, in particular to an ore pulp uniform separating box.

Background

In the mineral processing industry, no matter nonferrous metal or ferrous metal and non-metal industry, water is usually used as a medium for grinding classification and sorting operation, and one grinding classification system usually corresponds to a plurality of sorting devices, so that it is very important how to uniformly distribute ore pulp to each device. Therefore, various ore pulp separating boxes are widely used, and the separating boxes are not limited to the link, and the separating requirements may exist in each link in the ore dressing process.

Currently, pulp tanks are generally cylindrical and rectangular. The cylindrical ore separating box is a distributing device which equalizes ore pulp from the center to the periphery and enables the ore pulp to flow to each outlet, the ore separating uniformity is higher than that of the rectangular ore separating box, and the possibility of material deposition in the box body is small. The ore pulp enters the ore separating box through a chute or a pipeline and the like, and the ore pulp cannot be ensured to be positioned at the center of the cylindrical ore separating box, and is often biased to the feeding flow direction of the ore pulp. This will result in uneven flow rates and flows of pulp flowing out of the discharge ports of the separation tank (especially in the case of fluctuation of the incoming material of the separation tank), affect the stability and effect of subsequent grinding, classification, sorting and other processes, and also cause frequent adjustment of equipment to adapt to the fluctuating ore quantity. In addition, if a mode of increasing the overall size of the ore separation box to increase the flow stability of the ore pulp in the ore separation box and improve the ore separation effect is adopted, because the site often does not have such space conditions, and when the ore separation volume is increased, the mineral particles are settled and piled up at the places with slow flow velocity at the bottom, corners and the like, so that the uniformity of ore separation is affected, and uniform ore separation cannot be realized. In the control of the pulp conveying amount, a manual or electric valve moving or piston valve lifting mode is adopted to adjust the pulp amount of each outlet, the mode also needs to be qualitatively judged through experience on site, and meanwhile, the ore separating effect of the ore separating box is reversely pushed according to the visual expression condition of each subsequent operation, so that the operation efficiency is low, the valve is fast in abrasion, unstable production and large fluctuation are caused, and the production index is influenced.

Therefore, there is a need in the art to develop a structure and method that can achieve automatic and uniform separation of pulp.

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

Furthermore, references herein to "an embodiment" mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present utility model. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Fig. 1 is a front view of a slurry uniformity tank in accordance with an embodiment of the present utility model. Fig. 2 is a top view of a slurry uniformity tank in accordance with an embodiment of the present utility model. As shown in the figure, the ore pulp uniform ore separating box generally comprises a buffer cylinder 3, a buffer cylinder liquid level adjusting device 2 and an ore separating outer cylinder 4. The connection structure between the respective components is described in detail below.

A buffer cartridge 3 is provided in the central region of the overall apparatus for receiving slurry discharged from the upstream feed pipe 1. The buffer drum 3 may be cylindrical, and a plurality of diversion holes 31 are provided at a sidewall thereof, and the diversion holes 31 are used for distributing pulp to the peripheral diversion chamber 5. The plurality of diversion holes 31 are uniformly arranged along the circumferential direction of the damper cylinder 3. The diversion hole 31 may be specifically configured as an elongated hole, and the length direction of the elongated hole is parallel to the axis of the cylinder. The bottom of the diversion hole 31 is 100mm away from the bottom wall of the ore separation box, the top of the diversion hole 31 is 50mm away from the top of the ore separation box, the width of the diversion hole 31 extends along the circumferential direction, the width dimension is calculated according to the flow rate of ore pulp, and the liquid level in the central buffer cylinder 3 is required to be ensured not to be lower than 1/2 of the height of the central buffer cylinder 3. The inner side of the buffer cylinder 3 can be fully paved with wear-resistant materials such as cast stone blocks and the like so as to achieve the wear-resistant performance. During the use, because the central buffer cylinder 3 has a certain liquid level of ore pulp at any time, the central buffer cylinder has a certain buffering effect on the incoming ore, and the abrasion of the ore pulp halving box is further reduced.

The buffer vessel level adjustment device 2 comprises a bushing 21. The bush 21 is attached to the inner wall of the damper cylinder 3. The lining 21 can be made of wear-resistant materials such as wear-resistant rubber, polyurethane and the like, and the thickness of the lining is more than or equal to 10mm. The sidewall of the bushing 21 has a plurality of adjustment holes thereon for use with the shunt holes 31. For example, the number and shape of the adjustment apertures and the distribution apertures may be identical, and in the assembled state the two apertures are arranged immediately adjacent and at least partially overlap. The speed of the buffer drum 3 for conveying ore pulp to the ore separation chamber 5 is changed by controlling the size of the overlapping area of the buffer drum 3 and the ore separation chamber. When the overlap area is small, the actual available discharge size is small, the discharge flow rate is reduced, and when the overlap area is large, the actual available discharge size is large, and the discharge flow rate is increased.

In one embodiment, the bushing 21 is provided rotatably with respect to the damper cylinder 3, and the size of the overlapping area of the adjustment hole and the tap hole is changed by rotation of the bushing 21 with respect to the damper cylinder 3. After the bush 21 is rotated to the set position, a member such as a clip or a bolt may be used to fixedly hold the bush 21 and the damper cylinder 3 together so as to prevent the bush 21 from moving from the set position when in use. The structure is simple and easy to use and easy to implement.

In another embodiment, the draft tube level adjustment device 2 further includes a height adjustment mechanism 22. The height adjusting mechanism 22 mounts the bush 21 to the cushion cylinder 3 and is capable of changing the height of the bush 21 relative to the cushion cylinder 3. In some embodiments, the height adjustment mechanism 22 includes screw holes and screws. As shown in the enlarged partial view of fig. 1, the bush 21 has a first outer flange provided with a first hole through which a screw can pass. The shaft of the screw passes down through the first outer flange and is inserted into the buffer cylinder 3. The cap of the screw is located above the first outer flange. A catch is mounted under the bushing 21, via which catch the bushing 21 is rotatably held on the screw after mounting to the screw, i.e. the catch allows the screw to rotate in the first hole without the bushing 21 moving linearly along the stud. The damper cylinder 3 has a second outer flange provided with screw holes into which lower portions of the screws are screwed, and the height of the bush 21 relative to the damper cylinder 3 is adjusted by changing the screwing depth of the screws. The height adjusting mechanism 22 changes the relative heights of the adjusting holes and the diversion holes when changing the height of the bushing 21 relative to the buffer tube 3, so that the size of the overlapped area of the adjusting holes and the diversion holes is changed, and the pulp discharge flow is changed. With this structure, the pulp discharge can be adjusted and changed more finely.

The ore separation outer cylinder 4 is disposed at the periphery of the buffer cylinder 3 and is arranged coaxially with the buffer cylinder 3. The inner wall of the ore separating outer cylinder 4 is spaced apart from the outer wall of the buffer cylinder 3 by a predetermined region, which forms a region for discharging ore downward. The ore separation outer cylinder 4 may share the same bottom wall as the buffer cylinder 3. A plurality of partition plates are provided in the region between the ore separation outer cylinder 4 and the buffer cylinder 3, each of the partition plates extending in the radial direction. The partition plate divides the discharge area into a plurality of separate chambers 5, and the bottom wall of each separate chamber 5 is provided with a discharge opening 6. Each of the ore separation chambers 5 communicates with the area surrounded by the buffer drum 3 via one of the flow separation holes 31.

When the ore pulp uniform distribution box is used, ore pulp enters the buffer cylinder 3 in the center through the ore feeding pipe 1 or the chute, respectively enters different ore distribution chambers 5 through the distribution holes 31 on the side wall of the buffer cylinder 3, and enters the next working procedure from the ore discharge port 6 at the bottom of the ore distribution chamber 5. Under normal conditions, the liquid level in the central buffer cylinder 3 is maintained at a medium-high liquid level within the range of 1/2-2/3 of the height of the buffer cylinder, and the pulp passing through each ore separation chamber 5 is more uniform under the medium-high liquid level. When the ore quantity is continuously less, the liquid level in the central buffer cylinder 3 is lower, and under the condition, the buffer cylinder 3 cannot play a role in buffering, and the ore separation of the ore separation box is uneven. At this time, the buffer cylinder liquid level adjusting device 2 is operated to reduce the size of the overlapping area of the diversion hole 31 of the central buffer cylinder 3 and the adjusting hole of the bushing 21, so as to raise the liquid level in the central buffer cylinder 3, maintain the liquid level within the range of 1/2-2/3, and make the pulp passing through each ore separation chamber more uniform at the middle and high liquid levels. When the ore quantity is continuously large, ore pulp in the central buffer cylinder 3 is splashed out, at the moment, the buffer cylinder liquid level adjusting device 2 is operated, the size of the overlapping area of the diversion hole 31 of the central buffer cylinder 3 and the adjusting hole of the bushing 21 is increased, so that the liquid level in the central buffer cylinder 3 is reduced, the liquid level in the central buffer cylinder 3 is maintained at a medium-high liquid level in the interval range of 1/2-2/3, and the ore pulp quantity passing through each ore separation chamber is more uniform under the medium-high liquid level.

The inside structure of the ore separating box is novel, potential energy generated when ore pulp falls is reduced, impact and abrasion of the ore pulp to the ore separating box are reduced, the service life of each barrel is prolonged, and the inside ore pulp liquid level of the ore separating box can be adjusted, so that the ore separating box can be suitable for different working conditions, meanwhile, the ore separating uniformity is improved, and the production process is stabilized.

The utility model also provides a method for separating ore by using the ore pulp uniform ore separating box. The method comprises the following steps: receiving the upstream slurry with a buffer cartridge; observing whether the liquid level height in the buffer cylinder is in a set height range; if the liquid level in the buffer cylinder is higher than the set height, operating the buffer cylinder liquid level adjusting device to increase the overlapping area of the diversion hole and the adjusting hole until the liquid level in the buffer cylinder is adjusted to be within the set height range; if the liquid level in the buffer cylinder is lower than the set height, the liquid level adjusting device of the buffer cylinder is operated to reduce the overlapping area of the diversion hole and the adjusting hole until the liquid level in the buffer cylinder is adjusted to be within the set height range.

This method also has significant advantages in correspondence with the effects of the slurry uniformity tank of the present utility model.
