Multi plate screw press sludge dewatering machine

The present invention provides a multi plate screw press sludge dewatering machine and a helical shaft thereof. The multi plate screw press sludge dewatering machine includes fixed rings, movable rings, the helical shaft, a sludge inlet tank and a sludge discharging tank; the helical shaft adopts a variable diameter variable pitch helical shaft, a lead angle arrangement sequence of a helical blade of the whole helical shaft is gradual reduction from the sludge discharging tank to the sludge inlet tank, and the lead angle arrangement sequence is gradually reduced from 16°-22° to 6°-14°; a pitch of the helical shaft is gradually increased along a direction from the sludge inlet tank to the sludge discharging tank; a diameter of a shaft body of the helical shaft is gradually increased along with a direction of the sludge discharging tank from a ⅓ position of a shaft length; and blockage prevention plates are arranged on two sides of the bottom of the helical blade. The helical shaft in the present invention is specially designed, so that the pitch is more reasonable, a helical angle is gentler, frictional resistance when sludge passes through the helical shaft may be effectively reduced, and phenomena of shaft blockage and shaft sticking of the sludge may be reduced.

Coil built-in semiactive vibration absorber with closed structure

The invention aims to provide a coil built-in semiactive vibration absorber with a closed structure. The coil built-in semiactive vibration absorber comprises an outer shell, a base, a shaft, an armature, a spring, an upper cover and a ferromagnetic coil, wherein the outer shell is connected with the base; the upper cover is arranged on the outer shell; the armature is arranged in the outer shell and is connected with the outer shell; the shaft passes through the armature and is arranged on the base; a spring for positioning is arranged between the shaft and the armature; the outer shell, the base and the upper cover form the closed structure; an annular slot is formed on the central outer wall of the armature; and the ferromagnetic coil is arranged in the annular slot. A base supporting mode replaces a shaft supporting mode, so the gravity center is reduced, the supporting area is increased, the installation stability is improved, and the anti-swing capacity of the supporting mode is about within 45 degrees. A coil winding is combined with an active cell mass block, so the mass of a stator is reduced relatively and the mass of an active cell is increased; therefore, the volume of the whole vibration absorber is reduced, the effective mass of the vibration absorber is increased and the working efficiency and the applicability are improved.
