Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1-3:

a barite tailing separation device comprises a crushing tank 1, wherein a rotary crushing disc 2 is mounted at the bottom of the crushing tank 1, a plurality of circles of hammer blocks A21 are uniformly arranged along the surface of the crushing disc 2, and a high-pressure cyclone is further mounted on the peripheral wall of the crushing tank 1 close to the crushing disc 2; evenly arrange a plurality of hammer block B22 along the perisporium of broken dish 2, broken jar 1 top installation converges and covers 11, and its and broken jar 1 juncture sets up sieve 5, and feed arrangement is installed to broken jar 1 in sieve 5 downside.

The working principle is as follows: the barite ore which is primarily crushed by the jaw crusher enters the crushing tank 1 from the feeding device and then falls into the crushing disc 2, the ore is thrown away or crushed under the action of centrifugal force rotating at high speed and the hammer block A21, the thrown ore is further subjected to secondary or multiple collision crushing with the hammer block B22 on the peripheral wall of the crushing tank 1, the thrown ore rises along with the rotation of the airflow under high-pressure spiral airflow generated by a high-pressure cyclone when being crushed to a certain particle size, and is subjected to collision crushing with the hammer block B22 for multiple times in rising or is collided with each other for crushing, the cross sections of the hammer block A21 and the hammer block B22 are isosceles trapezoids in consideration of durability and throwing and flying capacity, the edge angles on two sides of the hammer block A21 and the hammer block B22 are used for striking and crushing, and the edge surfaces can play the roles of striking and throwing at the same time.

Qualified ore grain of particle diameter will follow the air current and pass through from the sieve to discharge from converging cover 11, later through separation such as cyclone can, and what be unqualified will carry out the high-speed rotatory breakage that lasts in inside, until the particle diameter is qualified, the ore that the particle diameter reduces simultaneously will be separated by the air current and the ore of bottom broken dish 2 immediately, makes the large granule ore of bottom obtain faster breakage.

The high-pressure cyclone can be generated by tangential air flow, for example, by connecting a plurality of tangential air distribution pipes 4 on the peripheral wall of the crushing tank 1, the air distribution pipes 4 are distributed by an annular pipe 42, and the inlet of the annular pipe 42 is connected with a high-pressure air supply pipe 43 for supplying air, so as to generate spiral air flow.

The effect of feed arrangement is mainly in order to avoid the air current to flow backward, unable feeding, so can adopt spiral delivery mechanism, perhaps set up conveying pipeline 3 of slope and vertical inlet pipe 31 of being connected with conveying pipeline 3, at the relevant fan 32 of inlet end installation of inlet pipe 31, realize the feeding through closing fan 32, though the export of gas distribution pipe 4 is high-pressure draught, can not pile up the granule, but avoid the bold ore to hit the back card and go into, can all install porous steel plate 41 at gas distribution pipe 4 exit end.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
