Configuration system for high concentration strong acid mixing

Abstract

The invention discloses a configuration system for high concentration strong acid mixing. The configuration system comprises a feeding device, a mixing and stirring mechanism, and a gas processing device. The mixing and stirring mechanism comprises an enclosed mixing container and a magnetic stirring machine arranged on the bottom of the mixing container; the feeding device comprises at least one feeding part, each feeding part comprises a liquid feeding pipe, which extends from top to bottom, the lower part of the liquid feeding pipe is communicated with the interior of the mixing container; the gas processing device comprises a cooling tank and a reflux condensation pipe that extends from bottom to top, the upper part of the reflux condensation pipe is embedded into the cooling tank, and the lower part of the reflux condensation pipe is communicated with the interior of the mixing container. The feeding device, the mixing and stirring mechanism, and the gas processing device are combined to form a configuration system, which can make the operation for mixing or diluting high concentration strong acids become safer and more efficient, and at the same time, the configuration system can accurately control the feed amount of raw materials, mixed solution concentration and reaction temperature. The configuration system is suitable for mixing or diluting high concentration strong acids.

Description

Technical field [0001] The invention relates to the field of chemical equipment, in particular to a configuration system for mixing high-concentration strong acids. Background technique [0002] Small medical devices such as dental implants and medical screws are widely used in dental and orthopedic operations. The surface morphology and composition of metal implant materials are critical to biocompatibility. Among them, the acid etching treatment is an indispensable process in the surface treatment of metal implant materials. However, there is no special equipment for the configuration of strong acid mixing. The traditional strong acid mixing configuration generally adopts the form of direct pouring for mixing. This mixing method has the following shortcomings and shortcomings: acid volatilization is serious, and the acid mist generated by the violent exotherm during the mixing process can easily cause environmental pollution; the container is easy to corrode. The service life...

However, for the configuration of strong acid mixing, there is currently no special equipment

The traditional strong acid mixing configuration generally adopts the form of direct pouring for mixing. This mixing method has the following disadvantages and deficiencies: the acid volatilization is serious, and the acid mist generated during the mixing process accompanied by violent heat release is easy to cause environmental pollution; the container is easy to corrode, The service life is short; no protective measures are taken during the strong acid mixing operation, which will cause corrosion of metal objects in the production workshop, affect the appearance and service life of the workshop, and also pose potential safety hazards
