[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a glucosamine hydrochloride impurity removal device, whose structure includes a mixing tank, a crude salt input pipe, a water inlet pipe, a connecting pipe, a sedimentation tank, a sedimentation tank partition, an output booster pump, a separation tank, an ultrafiltration membrane, a concentrated liquid output pipe, and a drain pipe. The front end of the mixing tank is connected to the crude salt input pipe and the water inlet pipe, the mixing tank is connected to the sedimentation tank through a connecting pipe, a sedimentation tank partition is arranged in the sedimentation tank, the rear end of the sedimentation tank is connected to the output booster pump through a pipeline, the output booster pump is connected to the separation tank, an ultrafiltration membrane is arranged in the separation tank, the interior of the ultrafiltration membrane is connected to the concentrated liquid output pipe, and a drain pipe is arranged at the bottom of the separation tank.

[0008] Furthermore, a stirring rod is provided in the mixing tank, and the stirring rod is connected to the stirring motor.

[0011] Furthermore, an output control solenoid valve is provided on the concentrated liquid output pipe.

[0012] By adopting the above-mentioned technical scheme, the beneficial effects of the utility model are as follows: the glucosamine hydrochloride impurity removal device improves the existing technology which can only separate solid phase impurities, cannot process liquid phase raw materials, and cannot separate impurities with a molecular weight smaller than that of glucosamine hydrochloride during actual use. Impurities such as water-insoluble chitin introduced into the raw materials are removed by precipitation, and then impurities with a molecular weight smaller than that of glucosamine hydrochloride are removed by filtration with an ultrafiltration membrane. These components are discharged from the drain pipe together with water, and the product is concentrated inside the ultrafiltration membrane, so that a solution with a higher concentration can be output, and the subsequent concentration steps are reduced, thereby improving work efficiency.
