Automatic cleaning system of conical spiral mixer and cleaning technology for conical spiral mixer

Abstract

The invention relates to an automatic cleaning system of a conical spiral mixer and a cleaning technology for the conical spiral mixer. The automatic cleaning system comprises a control system; a group of fixed nozzles are mounted on the side wall of a mixer cylinder body; spiral cleaning nozzles are arranged at the center of the mixer cylinder body and mounted downward from the top end of a mixer common rotation drive device; a sensing localization device is mounted at the top end of the mixer common rotation drive device; the sensing localization device is relative to a stirring propeller in position; a water treatment recycle system comprises a clean water storage tank, a return water storage tank, an acid-alkali liquor storage tank, an acid-alkali liquor addition pump, a centrifugal filter, a cleaning water pump and a pipeline valve; under the effects of the control system, the water treatment recycle system can be used for flexibly switching the technology steps of adding water, heating, washing with hot water, cleaning with alkali liquor, washing with the hot water, cleaning with acid liquor, washing with the hot water, and carrying out return water treatment.

Description

Technical field [0001] The invention aims at the hygienic level requirements of the conical spiral mixer in the medicine and food industries, and is designed to improve the cleaning effect of the equipment, complete automation and program control, and is an automatic cleaning system applied to professional equipment. Background technique [0002] Conical spiral mixer is widely used in food, medicine, chemical industry and other fields, and has the characteristics of high cost performance, low energy consumption, good mixing effect, high sanitation level and strong adaptability. However, in the application of food and pharmaceutical industries, the problem that plagues the use of this type of mixer is: because the mixing equipment is a container fixed mixer, there is a planetary spiral mixing mechanism inside the cylinder, the structure is relatively complicated, and the mixing materials are mostly Powders of various particle sizes and physical properties tend to stick to the wall...

Problems solved by technology

However, in the application of food and pharmaceutical industries, the problem that plagues the use of this type of mixer is: because the mixing equipment is a fixed container mixer, there is a set of planetary spiral mixing mechanism inside the cylinder, the structure is relatively complicated, and most of the mixing materials are Powders of various particle sizes and physical properties often stick to the wall, which leads to a low degree of equipment cleaning automation. The traditional automatic cleaning system cannot achieve the cleaning effect and is easy to breed bacteria; while manual cleaning is time-consuming, laborious and costly

With the continuous improvement of the industry's automation level, the cleaning automation of conical screw mixing equipment has become a bottleneck restricting the use and promotion of equipment. In order to improve production efficiency, some enterprises have to abandon the use of conical screw mixers and use other forms of mixing equipment. , but the mixing effect is not ideal
