Example Embodiment

[0063] In order to better explain the content of the present invention, the technical solutions of the present invention will be described below with reference to the drawings and specific implementations.

[0064] figure 1 It is a schematic diagram of a conventional stone-lined overflow type vertical shaft impact crusher. The stone mainly overflows into the central inlet 5 of the hopper 1 and enters the hopper 6 and then enters the rotor 7. It is ejected from the passage of the rotor 7 to the middle stone lining cavity 2 of the middle body 3, and the starting stone will be in the middle stone lining cavity 2. Pile up to the angle of repose of the stone, and the stone lining is formed. Subsequent stones will hit this stone lining, protecting the stone lining cavity 2. The collision between the stone and the stone lining will break the stone and produce a large amount of sand and stone powder, and the sand will fall from the space between the middle body 3 and the rotor 7. Part o...

Abstract

The invention relates to a vertical shaft type impact crusher with a powder and dust removal function. The vertical shaft type impact crusher with the powder and dust removal function is characterizedin that upper air suction pipes are arranged, directly communicate with the positive-pressure air space on the periphery of a rotor and do not directly communicate with other normal-pressure and negative-pressure air spaces, and the upper air suction pipes and other normal-pressure and negative-pressure air spaces are in an indirect communication relationship only through rotor channels; and theupper air suction pipes communicate with an air exhaust pipeline of a powder and dust removal system, and an exhaust fan of the powder and dust removal system sucks the positive-pressure powder air onthe periphery of the rotor through the air exhaust pipeline and the upper air suction pipes. By the adoption of the vertical shaft type impact crusher with the powder and dust removal function, mutual interference of the air flow is avoided, the phenomenon that powder and dust is circularly and repeatedly crushed in the machine is avoided, the amount of powder and dust is reduced, the negative pressure is formed in an inlet and an outlet of the machine, and no powder air overflows.

Description

technical field [0001] The invention relates to a vertical shaft impact crusher, in particular to a powder and dust removal vertical shaft impact crusher and a powder and dust removal method. Background technique [0002] The vertical shaft impact crusher is a crusher that uses a completely different working principle from the traditional crusher. The impact rotor rotates at a high speed of about 1500 rpm, and the linear speed of the rotor edge reaches a speed of more than 60m / s. The material is fed from the center. , by accelerating the crushable material to a speed of up to 60m / s, hitting the iron wall lining or stone wall lining to achieve the purpose of crushing the crushable material, especially for the crushing effect of small and medium-sized crushable materials. There is also a vertical shaft impact crusher using a combination of double rotors, and has an upper and lower rotor structure, the upper rotor is an impact rotor, and the lower rotor is a hammer rotor. Hamm...
