Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are merely exemplary of the invention and are not intended to be exhaustive. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example (b):

the utility model provides a pair of make thick liquid system, as shown in fig. 1, make thick liquid system including feeding device, receiving device, bath device, screening plant, ball mill 5 and collection device, receiving device sets up in the feeding device below, and bath device sets up the receiving device side, and screening plant sets up in the receiving device below, and ball mill 5 sets up and is used for grinding the mineral aggregate that screening plant rolled down in the screening plant below. It is to be noted that for sufficient grinding, the rotational speed of the ball mill should be greater than 18 r/min.

Wherein, collection device includes receipts hopper 601 and thick liquid pond 6, receives hopper 601's one end and thick liquid pond 6 intercommunication, receives hopper 601's the other end setting in screening plant below. In addition, the material conveying device includes but is not limited to a belt 1 conveying device composed of a belt 1, a driving wheel and a driving motor, and can also be a crawler belt conveying device and the like.

Particularly, receiving device includes that a plurality of layering set up between bath device and screening plant and along bath device to the constantly roll portion that connects material 3 component of extension of screening plant. It is anticipated that through setting up multilayer material spare 3 and making the mineral aggregate have a chance that fully rolls and rub each other, then can realize that powdered ore and tiny particle ore and large granule ore separate in the short distance and accomplish the thick liquid, then can reduce the length of short material spare 3, save material.

The flushing device comprises a water pump 2, a water supply pipe 201 and a spray head 202, wherein the spray head 202 is connected with the water pump 2 through the water supply pipe 201. The water outlet end of the spray head 202 is arranged at one end of the material receiving part 3, and the other end of the material receiving part 3 is arranged above the screening device.

When the dry and wet mixed mineral aggregate falls from the material conveying device onto the material receiving member 3, the water sprayed from the spray head 202 impacts the mineral aggregate to make the mineral aggregate move and roll on the material receiving member 3, so as to form a mixture of ore pulp formed by mineral powder and fine particle ore and large particle ore mixed together. The mixture finally slides out of the material receiving part 3 to the screening device, ore pulp passes through the screening device and directly enters the pulp tank 6 through the material receiving hopper 601, and large-particle ore is screened by the screening device to the ball mill 5 for grinding. It should be noted that the water sprayed from the spray head 202 is not only an essential condition for slurry making, but also a power for pushing the mineral aggregate to slide from the receiving member 3 to the sieving device, so the pressure of the water pump 2 should be at least equal to or greater than 300 kPa.

It should be noted that some protruding structures 301 may be disposed on the material receiving member 3 at intervals, of course, the positions of the protruding structures 301 may be uniform or non-uniform, and the positions of the protruding structures may be the bottom or the side walls of the material receiving member 3, or both the bottom and the side walls. The shape and number of the raised formations 301 may be arranged as required, provided that the movement of the mineral material towards the screening device is not affected. Like this mineral aggregate and protruding structure 301 have a collision friction's effect, will make the ore powder and the ore of tiny granule can more complete efficient mix with water and drop from the large granule ore and form the ore pulp, make and make the thick liquid effect better. In addition, a more complete effect of the slurrification can be achieved if the receiving part 3 is arranged long enough without the projection structure 301, since at a sufficiently long distance the ore particles collide with each other sufficiently to achieve a sufficient slurrification. Of course, the material receiving member 3 with a sufficient length can be provided with the protrusion structure 301 therein to further improve the effect, and the length of the material receiving member 3 with the protrusion structure 301 can be correspondingly shortened.

It should be noted that the shape of the receiving member 3 includes, but is not limited to, a common laminate, a concave groove, and may also be a cylindrical channel, a water spraying hole is provided on the wall of the cylindrical channel, and the nozzle 202 sprays water into the cylindrical channel through the water spraying hole, which not only can implement slurry making, but also can avoid flushing mineral aggregate out of the receiving member 3. And the material receiving piece 3 with the cylindrical channel is adopted, and the position of the ore pulp mixture flowing out of the material receiving piece is fixed, so that the ore pulp mixture after pulp making can better flow to the screening device. In addition, it is also an embodiment to provide some kind of baffle or raised structure 301 in the cylindrical channel to collide with the ore material to separate the fine and fine particles from the large particles to achieve sufficient slurrying. Of course, the cover plate is additionally arranged on the concave groove, so that the mineral aggregate can be prevented from being flushed out of the receiving part 3.

As an embodiment, the ore powder and the fine particle ore can be separated from the large particle ore to realize full slurry making by arranging a stirring blade in the material receiving part 3 like driving a motor to stir the ore material.

Screening plant is including sieve body 4 and vibrations portion, and 4 vibrations of drive sieve body 4 are connected to vibrations portion sieve body. After the slurry mixture contacts the screen body 4, the large-particle ore is sent to the ball mill 5 under the vibration of the screen body 4 to be ground and then flows to the collecting device, and other slurry directly flows to the collecting device. It is worth explaining that, in order to fully realize the screening effect, the amplitude of the screen body should be larger than 5mm, and the vibration time should be larger than 5 seconds. The screen body 4 is designed to be inclined, the inclination direction of the screen body 4 is towards the ball mill 5, and the large-particle ore after being screened can be conveniently rolled towards the ball mill 5 through the inclined screen body 4.

Of course, the screening device can be only a single screen, as long as the length of the screen is enough, the ore pulp naturally has enough time to flow down from the screen, other large-particle ores naturally have enough time to be separated from the ore pulp and roll to the ball mill 5, the vibration part can be omitted, and energy is saved. Wherein, screening plant also need not slope setting, adopts the rectilinear sieve also can realize screening effect, but adopts the rectilinear sieve just must provide corresponding power and drive large granule ore movement to ball mill 5.

The form of the arrangement of the collecting device can also be varied, not only in that it is composed of a receiving funnel 601 and a slurry tank 6, but also in that it can be a single container, arranged directly below the sieve body 4 and the ball mill 5 for collection.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
