Liquid mixing device and control method

Abstract

The invention discloses a liquid mixing device. The liquid mixing device comprises a liquid supply assembly, a liquid filling assembly and a control assembly, wherein the liquid supply assembly comprises a first liquid storage pool, a second liquid storage pool, a mixing pool and an agitator; the liquid filling assembly comprises a belt, an infrared sensor, an electromagnetic valve and a conveyingbottle; the control assembly is a central controller; the first and second liquid storage pools supply a liquid to the mixing pool according to a preset proportion; the mixing pool is arranged rightabove the belt; the electromagnetic valve is arranged below the mixing pool; the conveying bottle is placed on the belt; and the infrared sensor is arranged on the side of the belt. The liquid mixingdevice is capable of replacing manual operation to solve the problem that the liquid mixing machines in the prior art are low in accuracy and unreliable in control, is safe, reliable and convenient tomaintain, and is capable of accurately controlling the ratio of variety of liquid, carrying out uniform mixing, realizing continuous and stable production, reducing the labor intensity and improvingthe working efficiency.

Description

technical field [0001] The invention relates to the field of weighing and batching, in particular to a liquid mixing device and a control method. Background technique [0002] The mixing of liquids has a wide range of applications in the medical industry; chemical industry; pharmaceutical industry, and paint industry. The traditional method of blending is to manually mix and bottle different doses of liquids based on measured standards. However, this mixed processing method has a large degree of human intervention, high production costs, lack of product consistency, and easily causes product quality problems due to human errors. In special industries, such as oil refining, chemical industry and other industries, due to the presence of corrosive, toxic and flammable and explosive media, the working environment is very harsh, and it is not suitable for staff to operate on site. [0003] Mixers in the prior art, for example, patent CN201220422090.X discloses a liquid mixer, i...
