Background

The horizontal screw machine is a general-purpose device for performing solid-liquid separation by using centrifugal force generated by high-speed rotation: after the separated material enters the drum, the solid phase is quickly settled to the inner wall of the drum and the liquid phase is settled to the surface of the solid phase under the action of centrifugal force because of the density difference between the solid and the liquid. The rotary drum and the spiral rotate in the same direction, a rotation speed difference exists between the rotary drum and the spiral, the solid phase is pushed to a slag outlet at the small end of the rotary drum under the action of the spiral, and the liquid phase is naturally discharged through a liquid outlet on the shaft of the large end cover. When a horizontal screw machine is used for processing certain compressible materials, in order to reduce the water content of a solid phase and improve the clarity of a liquid phase, a special baffle plate, which is generally called a BD plate, is usually added to a spiral conical section. In prior art, the BD board is as a ring, welds the spiral cone section after the unloading cutting usually in advance, and the external diameter of BD board needs to adjust according to the material actual conditions sometimes, at the engineering scene, if discover the BD board size is improper through debugging repeatedly, can only cut original BD board, welds new BD board again, if the use field does not possess the transformation condition still need to send the spiral back to original factory and transform, wastes time and energy, seriously influences use unit production efficiency. Therefore, how to conveniently and quickly adjust the size of the outer circle of the BD plate becomes a difficult problem which needs to be solved urgently by manufacturers of the horizontal screw machine.
