Description

Voluminous product swirler

Technical field

The utility model belongs to mineral manufacture field, is related to a kind of ore pulp classifying equipoment more particularly to a kind of rotation of multi-product Flow device.

Background technique

Hydrocyclone has been used widely since nineteen thirty-nine is for industry in fields such as ore dressing, chemical industry.But at present Until, the cyclone space that classification efficiency is still improved in application process, traditional cyclone imitates classification using centrifugal force field An important factor for rate improves, and the disorder of interior flow field and the presence of air column are its classification efficiencies of restriction, and two can only be separated A product, i.e. two granularity level, this not only limits the effectiveness of classification of cyclone, can not meet the material to multiple ranks Carry out the needs of gradation and optimization.How cyclone classification efficiency and effectiveness of classification are further increased, and can the multiple ranks of output Always studied personnel's concern.

It was verified that classification efficiency improves 30%, ore grinding total energy consumption can reduce by 20%, and the quality of classifying equipoment is to ore grinding It is crucial to entire ore dressing process.Therefore, a kind of high-precision is invented, the classifying equipoment of high score stage efficiency has important meaning Justice.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of more grade-classification cyclones of brand new, it is intended to The classification efficiency and effectiveness of classification of cyclone are improved, meanwhile, more grade products can be obtained as needed.

The technical solution that the utility model solves above-mentioned technical problem is as follows:

Spiral guide plate, the spiral shell is arranged in a kind of fecund product swirler, including cylinder, overflow pipe, top cover, the inner barrel Revolve the middle overlapping of axles of guide plate and the cylinder；The cylinder top opens up a feed port；The bottom end of the cylinder opens up multiple Sand sinking port, each sand sinking port are arranged in the gap of spiral guide plate；The top of the cylinder and top cover are fixedly linked, described Overflow pipe injects the center of the cylinder and spiral guide plate by the top cover.

Preferably, the cylinder is cylindrical empty barrel with the end, and diameter 250mm-1000mm is highly 250mm- 1000mm。

Preferably, the spiral guide plate is loose egg roll structure, and the spacing between the two adjacent rings of the spiral guide plate is 10mm-50mm。

Preferably, the feed port is a hollow siphunculus, and one end is tangentially connected with the outer wall of cylinder, and break-through cylinder Wall tangentially enter the inside of the cylinder.

Preferably, the top cover is circle, and the diameter of the top cover is equal with the diameter of the cylinder.

Preferably, the top cap central opens up a round cavity, and the overflow pipe can be injected from the round cavity The center of the cylinder and the spiral guide plate.

Preferably, the sand sinking port adjusts caliber size using replaceable reducer pipe.

Preferably, the overflow pipe is to be fully welded to connect with the top cover, and the top cover is to be fully welded to connect with the cylinder, institute It is to be fully welded to connect that cylinder, which is stated, with the feed port, and the cylinder is to be fully welded to connect with the sand sinking port.

The working process of the utility model is as follows: ore pulp to be fractionated tangentially feeds the cylinder of cyclone from feed port, in spiral Ecto-entad spiral rotating advances under the restricting guide of guide plate.Since spiral guide plate radius is gradually reduced, the linear speed of pulp flow Degree is gradually increased, and under the action of the centrifugal force, centrifugal sedimentation occurs for the solid particle in ore pulp, is led by gradually class settling to spiral On plate, it is then snapped down to sand sinking port, thicker ore particle is more deposited in the outer ring of spiral guide plate, and thinner ore particle ore particle is more deposited in The inner ring of spiral guide plate, and be discharged from respective sand sinking port, the most thin ore particle being unable in centrifugal sedimentation to spiral guide plate It is flowed out from overflow pipe, to obtain the product of multiple grades.

Compared with prior art, the utility model has the beneficial effects that

(1) the utility model product is because being provided with spiral guide plate, substantially increases ore pulp in internal runing time, by In the extension of ore pulp runing time, the grading time of ore particle is greatly prolonged, reduces the distance that solid particle reaches side wall, thus Working efficiency is improved, and reduces the disorder of ore pulp, substantially eliminates the adverse effect of air column.

(2) spiral guide plate of the utility model product setting can force the run trace of control ore pulp, make ore pulp in cylinder Spiral is advanced in an orderly manner in vivo, not disorder, and the grain graininess in ore pulp reduces from the outer ring of spiral guide plate to inner ring in gradual change Distribution, therefore multiple ranks can be obtained as needed, so that effectiveness of classification and classification efficiency be made to increase substantially.

(3) the utility model product because be provided with spiral guide plate ore pulp is rotated in cylinder during by ore particle by It is gradually classified, the multiple grades that can be needed with output, and common cyclone can only generate two grades.
