Internal cleaning mechanism and method for spiral mandrel of horizontal screw machine

Abstract

The invention relates to an internal cleaning mechanism for a spiral mandrel of a horizontal screw machine. The internal cleaning mechanism for the spiral mandrel of the horizontal screw machine comprises a sleeve arranged on a feed pipe in a sleeving mode, a closed cavity is formed between the sleeve and the feed pipe, a water inlet connected with the outside is arranged at one end of the sleeve,and a plurality of cleaning nozzles are arranged on the sleeve. The internal cleaning mechanism for the spiral mandrel of the horizontal screw machine has the advantages that the special cleaning mechanism is additionally arranged in the spiral mandrel of the horizontal screw machine, and the interior of the spiral mandrel of the horizontal screw machine can be thoroughly cleaned without dead angles under the condition that the machine is not disassembled, so that the requirements of special industries such as biopharmacy and food are met.

Description

technical field [0001] The invention relates to a cleaning mechanism and a cleaning method, in particular to a cleaning mechanism and a cleaning method inside a spiral mandrel of a horizontal screw machine, belonging to the technical field of engineering machinery. Background technique [0002] The horizontal screw machine is a general-purpose equipment for solid-liquid separation using the centrifugal force generated by high-speed rotation. After the separated material enters the drum, due to the density difference between the solid and the liquid, the solid phase will settle rapidly under the action of the centrifugal force. to the inner wall of the drum, and the liquid phase settles to the surface of the solid phase. The drum and the screw rotate in the same direction, and there is a speed difference between the drum and the screw. The solid phase is pushed to the slag outlet at the small end of the drum under the action of the screw, and the liquid phase passes through t...

AI Technical Summary

Problems solved by technology

However, in some special industries, such as biopharmaceutical and food industries, it is necessary to fully and thoroughly clean the inside of the decanter screw machine, especially the inside of the screw mandrel must be cleaned without dead ends and without any residue, which usually requires dismantling , that is to disassemble the screw from the drum, and then flush the inside with water. It usually takes 2-3 people to work for about 3 hours to complete the disassembly and installation, which is time-consuming and laborious.
