The reaction device comprises a dilute sulfuric acid tank, a salt transfer tank, a plate frame filter and a refined liquid tank; the dilute sulfuric acid tank is communicated with the interior of the salt transfer tank through a dropping tube, a blanking valve of the salt transfer tank is connected with a feedingport of the plate frame filter through a blanking pipe, the plate frame filter is provided with two discharging ports, and the two discharging ports are externally connected with refined liquid pipes; the outer ends of the refined liquid pipes are communicated with each other through a switching pipe, the switching pipe is communicated with the top of the salt transfer tank through a return pipe,the return pipe is provided with a return valve and a viewing vessel, the switching pipe is connected with the refined liquid tank through a terminal filter pipe, and the terminal filter pipe is provided with a discharging valve. According to the device, through the optimization arrangement of a pipeline, the equipment investment is small, the cumbersome suction filtration process is simplified,and the operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of neomycin sulfate production equipment, and in particular relates to a reaction device used for the refining process of neomycin sulfate. Background technique [0002] In the production process of neomycin sulfate, the concentrated solution of neomycin is refined into salt by adding sulfuric acid to adjust the pH value, and then transformed into neomycin sulfate. Due to the technical influence on the light transmittance of the refined solution of neomycin sulfate and the finished product Strict requirements, after the neomycin concentrated solution is refined and converted to salt, it is necessary to put in an appropriate amount of activated carbon to decolorize the refined solution, and then separate the activated carbon to become a qualified neomycin sulfate refined solution.

[0002] In the production process of neomycin sulfate, the concentrated solution of neomycin is refined into salt by adding sulfuric acid to adjust the pH value, and then transformed into neomycin sulfate. Due to the technical influence on the light transmittance of the refined solution of neomycin sulfate and the finished product Strict requirements, after the neomycin concentrated solution is refined and converted to salt, it is necessary to put in an appropriate amount of activated carbon to decolorize the refined solution, and then separate the activated carbon to become a qualified neomycin sulfate refined solution. There are many existing filtration equipment The plate and frame filter is used to separate the carbon liquid, but in the early stage of the filtration process, because the activated carbon cannot immediately form a carbon cake on the filter cloth, a part of the activated carbon will penetrate the filter cloth, causing the filtrate to leak carbon and become turbid. Once the activated carbon is formed on the filter cloth Carbon cake, the filtrate will gradually become clear in the later stage, how to distinguish whether the filtrate becomes clear

The conventional method is to first use a suction filter tank to hold the filtrate in the early stage, and continuously sample and observe from the sampling port of the plate and frame filter press until the filtrate becomes clear, then transfer the qualified filtrate to the refined liquid storage tank, and the unqualified filtrate in the early stage is passed through suction filtration. The tank is pressed into the salt tank to re-filter. This method is complicated to operate and easy to run out. Because of carbon leakage, the suction filter tank needs to be thoroughly cleaned after each use.
