Description

Technical field:

[0001] The utility model relates to the technical field of coarse coal slime separators, in particular to an interference device based on a coal slime separator. Background technology:

[0002] A coarse coal slime separator is a device that realizes intelligent sorting under the joint action of an ascending water flow and an interrupter based on the difference in the interference settling velocity of the material. When working, the coal slime material is mixed with the ascending water flow to form an "interference bed", and the material (clean coal) with a density lower than the sorting density moves upward, and the material (tailings) with a density higher than the sorting density moves downward, thereby completing the sorting; in the prior art, the interference device is usually a rotating paddle structure, such as Chinese Patent No. 201510347852.2 discloses a TCS intelligent coarse coal slime separator, which realizes interference sorting of coal slime by rotating the paddle. Although this paddle interference sorting effect is good, due to the huge size of the coarse coal slime separator, the diameter can reach more than 5 meters, and the paddle ruler of the corresponding size must be matched to meet the requirements. In addition, the resistance of the coal slime is large, resulting in the use of an ultra-high power motor to drive the blade rotation, which has high energy consumption. At the same time, due to the scouring of the coal slime during the rotation, the paddle wears greatly, and more frequent regular maintenance is required to ensure the normal production. Utility model content:

Specific implementation method:

[0016] Embodiment 1:

[0017] like Figure 1 and Figure 3As shown, an interference device based on a coal slime separator includes a coal slime machine barrel body 1, in which a vortex pneumatic interference component is installed, and the vortex pneumatic interference component includes a vortex ring tube 2, on which a plurality of airflow nozzles 3 are connected obliquely downward, and the air jets of the airflow nozzles 3 are directed toward the inside of the vortex ring tube 2, and an air intake pipe 4 is connected to the vortex ring tube 2, the air intake pipe 4 is installed on the coal slime machine barrel body 1 and extends to the outside of the coal slime machine barrel body 1, and the air intake pipe 4 is externally connected to a compressed air pipeline.

[0018] like Figure 4 As shown, the air jet port of the air flow nozzle 3 is conical, and an anti-clogging component is installed in the air flow nozzle 3, and the anti-clogging component is used to prevent coal slime from clogging the air flow nozzle 3; the anti-clogging component includes a sealing ball 5, a sliding rod 6 is connected to the sealing ball 5, a sliding plug 7 is connected to the sliding rod 6, and the sliding plug 7 is slidably connected to the air flow nozzle 3, a partition 9 is installed in the air jet port of the air flow nozzle 3, a sliding hole is opened on the partition 9, the sliding rod 6 is slidably connected to the sliding hole, an air hole 10 is opened on the partition 9, and a compression spring 8 is mounted on the sliding rod 6, and the compression spring 8 is located between the partition 9 and the sliding plug 7; in order to increase the vortex power of the compressed air, as shown in FIG. Figure 3 As shown, there are two or more intake pipes 4 , and the intake pipes 4 are tangent to the vortex ring pipe 2 , and all the intake pipes 4 are centrally symmetrical about the vortex ring pipe 2 .

[0020] During operation, compressed air is introduced into the air inlet pipe 4, and the compressed air is discharged through the air flow nozzle 3 after passing through the vortex ring tube 2. Due to the vortex-like arrangement structure of the air flow nozzle 3 in space, a vortex-like interference and stirring is generated on the coal slime, which can also achieve the interference and stirring effect of the transmission mechanical blades, but with reduced energy consumption and longer service life; in order to prevent the air flow nozzle 3 from being blocked, the air jet port of the air flow nozzle 3 is set downward, and in order to prevent the air flow nozzle 3 from being blocked by back suction when the air supply is stopped, an anti-clogging component is designed. When compressed air is introduced, the sliding plug 7 drives the sliding rod 6 to push the sealing ball 5 open, and the normal jet stirring operation is carried out. When the compressed air stops being introduced, the compression spring 8 causes the sealing ball 5 to seal the air flow nozzle 3 to prevent blockage accidents caused by the inhalation of coal slime.
