Horizontal screw centrifuge housing opening and limiting device

Abstract

The invention relates to a horizontal screw centrifuge housing opening and limiting device which comprises an opening mechanism arranged between an upper housing and a machine base of a horizontal screw centrifuge, the upper housing is hinged to the machine base through a rotating mechanism, and the upper housing forms a motion trail according to rotation of the rotating mechanism. A limiting mechanism for limiting the action of the upper housing is arranged at one end of the motion trail. The horizontal screw centrifuge housing opening and limiting device has the advantages that the structure is simple, disassembly and assembly are convenient, the housing can be opened only by slightly changing an existing structure, labor is saved when the housing is opened, and convenience and safety are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to an opening and limiting device for a cover of a decanter centrifuge. Background technique [0002] The decanter centrifuge is a processing equipment widely used in solid-liquid separation applications. Its working principle is that the drum and the screw pusher rotate at a high speed in the same direction with a certain difference in speed, and the fluid suspension composed of liquid and solid passes through the The feed pipe is continuously introduced into the screw pusher, and then enters the drum after being accelerated. Under the action of centrifugal force, the heavier solids are deposited on the drum wall to form a sediment layer, and the screw pusher continuously deposits the deposited solids. Push it to the cone drum and discharge through the slag outlet, and the resulting clear liquid flows to the other end of the drum and is discharged through ...

Problems solved by technology

However, this hinge opening device can only realize the opening and closing of the upper case, but cannot realize the positioning adjustment when the upper case is opened. The positioning position after the upper case is opened is determined by the torque and the torsion angle of the torsion spring. Manufacturing error, the torque and torsion angle of the torsion spring deviate from the design requirements, so that the upper cover cannot reach the designed opening positioning position and cannot be adjusted

In addition, it is very laborious to disassemble and assemble the torsion springs. The service life of the opening device depends on the quality of the torsion springs. The quality consistency of the four torsion springs is highly required. Once the torsion springs fail, they need to be replaced, which is very inconvenient.

Therefore, the cost of the hinge opening device is relatively high, and it is inconvenient to use and disassemble.
