An automatic batching device and batching method

Abstract

The invention discloses an automatic batching device and a batching method. The batching device includes a liquid feeding device, a solid powder feeding device and a mixing device. The liquid feeding device realizes liquid quantitative feeding through a liquid level meter and a flow control meter; The powder feeding device includes a powder storage tank and a weighing device. The powder storage tank is equipped with a first agitator to help the solid powder fall into the weighing device smoothly. The weighing device can realize accurate quantitative feeding of the solid powder; mixing The device includes a spray pipe, a feeding funnel, a mixing chamber, an accelerating tube, a dispersion chamber, a mixer and a mixed liquid storage tank, and all parts are closely matched with each other so that the solid powder is fully mixed in the liquid. In the batching method of the present invention, the PLC controller is used to control the actions of each component, and the parameters are set in the PLC in advance, and the batching is carried out according to the steps of weighing solid powder, solid powder blanking, and solid-liquid mixing. The degree of automation is high and the implementation standard Unification can effectively improve the quality of products.

Description

technical field [0001] The invention relates to an automatic batching device and a batching method, more specifically to an automatic batching device and a batching method capable of quantitatively preparing liquid raw materials and solid powder raw materials, and fully mixing the liquid and solid powder. Background technique [0002] The existing textile industry needs to use different chemicals as textile dyeing and finishing auxiliaries in the processing procedures such as spinning, weaving, printing and dyeing, so as to improve the quality of textiles, simplify the process, and make textiles have excellent performance. In the pre-treatment process of fabric printing and dyeing, the fabric needs to be washed with water, and the washing treatment needs to add reducing agents and bleaching agents, etc. The most commonly used is hydrosulfite (sodium dithionite), which is toxic and harmful to the eyes and respiratory tract mucous membranes. It is irritating, and sodium hydros...

AI Technical Summary

Problems solved by technology

[0004] The addition of sodium hydrosulfite in the prior art has the following deficiencies: 1. Hydrosulfite easily absorbs moisture in the air and agglomerates. After agglomeration, with the discharge of hydrosulfite below, no In the empty area of ​​sodium bicarbonate, sodium bicarbonate cannot fall from the storage tank to the follow-up device; 2. The weighing device cannot accurately weigh the required sodium bicarbonate, and the error is relatively large; 3. During the adding process of bisulfite, due to The sodium hydrosulfite particles are small and are easy to scatter around, resulting in waste of hydrosulfite, resulting in poor working conditions and seriously endangering the health of workers; 4. During the process of adding hydrosulfite to the mixing device, the dissolution rate is relatively slow. The existence of sodium hydrosulfite solid particles reduces the utilization rate of hydrosulfite, thus affecting the printing and dyeing effect
