The working principle of the utility model is that the connecting seat is fixedly connected to the bottom of the rotary drum, one end of the rotary shaft runs through the connecting seat and then is fixedly connected with the bottom of the rotary drum, so the rotary drum and the connecting seat can be driven to rotate synchronously through the motor, the connecting seat and the rotary drum have a certain rotating speed, and the bottom of the driving shaft and the rotary drum are connected in a rotating way, one end of the centrifugal rod is fixedly sleeved on one end of the driving shaft, a reset spring is connected between the other end of the centrifugal rod and the connecting seat, therefore, the centrifugal rod and the driving shaft both rotate synchronously along with the rotary drum, the slag hole can be shielded by the shielding plate at the moment, after the material is added into the rotary drum, the material is driven to rotate together by the rotary drum.
When solid phase in the rotary drum needs to be cleaned, the rotating speed of the connecting seat is increased through the motor, the centrifugal rod is kept to rotate at a high speed, the centrifugal force borne by the centrifugal rod is increased, one side of the centrifugal rod is connected to the other end of the driving shaft in a sleeved mode, a return spring is connected between the other side of the centrifugal rod and the connecting seat, the driving shaft is connected with the bottom of the rotary drum in a rotating mode, the driving shaft can limit the displacement direction of the centrifugal rod, only the centrifugal rod is allowed to rotate by taking the driving shaft as the center, the centrifugal rod rotates and compresses the return spring under the action of centrifugal force, the driving shaft is driven to rotate through the centrifugal rod, the driving shaft drives the shielding plate to rotate again, the shielding plate does not shield the slag outlet, the solid phase in the rotary drum falls out through the slag outlet, after the solid phase is cleaned, the rotating speed of.
The utility model has the advantages that: this scheme passes through the rotational speed of motor increase connecting seat, and then makes the centrifugal rod pass through the drive shaft and drive the shielding plate rotation, and the slag notch is no longer sheltered from to the shielding plate, and the solid phase in the rotary drum falls out through the slag notch, accomplishes the clearance to the solid phase.
Further, a gap is left between the edge of the shielding plate and the edge of the slag outlet. The purpose that sets up like this is that because the rotary drum can make the centrifugal lever produce certain centrifugal force when carrying out the centrifugation to the material, this centrifugal force makes the centrifugal lever take place less rotation, and then drives the shielding plate and takes place the rotation of small-amplitude, in order to prevent that a part of slag notch is not sheltered from by the shielding plate, consequently reserves the clearance between the edge of shielding plate and the edge of slag notch.
Further, the slag outlets are symmetrically arranged along the axis of the rotary drum. Through slag notch symmetry setting, the quantity of slag notch increases for the speed of clearance solid phase.
Further, one side of the slag outlet extends to the bottom of the inner side wall of the rotary drum. Because centrifugal action can make the interior material of rotary drum move towards the inside wall of rotary drum, make the solid phase save at the inside wall of rotary drum, therefore one side of slag notch extends to the bottom of rotating the inside wall, can increase the clearance efficiency to the solid phase.
