Description

Technical Field

[0001] This utility model relates to the field of cyclodextrin processing technology, and in particular to an integrated ultrafiltration and impurity removal device for decolorizing cyclodextrin derivatives. Background Technology

[0002] Cyclodextrin is a general term for a series of cyclic oligosaccharides produced from linear starch under the action of cyclodextrin glucosyltransferase produced by Bacillus. During the production of cyclodextrin and its derivatives, the presence of reducing substances causes the product solution to turn yellow under alkaline or high-temperature conditions, which seriously affects the quality of the product. Therefore, decolorization treatment is generally performed during the processing of cyclodextrin and its derivatives.

[0003] During the production of cyclodextrin derivatives, some impurities are often mixed in. Ultrafiltration membranes are usually used to filter them to ensure production quality. However, ultrafiltration membranes are easily clogged during use, which leads to a decrease in filtration efficiency and affects subsequent use. Therefore, we propose an integrated ultrafiltration impurity removal device for decolorization of cyclodextrin derivatives. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an integrated ultrafiltration and decolorization device for cyclodextrin derivatives.

[0005] This utility model is achieved using the following technical solution: an integrated ultrafiltration and impurity removal device for decolorizing cyclodextrin derivatives, comprising a tank, a feed pipe connected to the top of the tank, a hot air blower fixedly connected to the top of the tank, an air outlet pipe connected to the air outlet end of the hot air blower, an inner tank fixedly connected to the inner wall of the tank, a discharge pipe connected to the bottom of the inner tank, a first solenoid valve fixedly installed at the bottom of the discharge pipe, an activated carbon fiber filter fixedly connected to the bottom of the inner tank, a flushing assembly provided at the left end of the tank, an installation plate fixedly connected to the inner wall of the tank, an ultrafiltration membrane fixedly connected to the bottom of the installation plate, a discharge pipe and a slag discharge pipe connected to the bottom of the tank, and a mixing assembly provided in the middle of the tank; The rinsing assembly includes a fixing plate, a cleaning pump is fixedly connected to the top of the fixing plate, a water pump is connected to the left end of the cleaning pump and a water delivery pipe is connected to the right end of the cleaning pump, one end of the water delivery pipe extends to the tank and is connected to a rinsing pipe, and a second solenoid valve is fixedly installed at the connection between the water delivery pipe and the rinsing pipe.

[0006] By combining decolorization and ultrafiltration into one device, the operation process is simplified and production efficiency is improved. When the internal cleaning of the activated carbon fiber filter and ultrafiltration membrane is required, the water pumping pipe is placed into the external water source, the second solenoid valve is opened to connect the water supply pipe and the flushing pipe, and the cleaning pump is started. The cleaning pump draws water from the water source through the water pumping pipe and sends it into the interior of the flushing pipe through the water supply pipe. The water is sprayed out through several through holes on the flushing pipe to clean and regenerate the interior of the activated carbon fiber filter and ultrafiltration membrane, thus extending their service life.

[0007] As a further improvement to the above solution, the top of the fixing plate is fixedly connected to the bottom of the tank, and the surface of the flushing pipe is fixedly connected to the inner wall of the activated carbon fiber filter and the ultrafiltration membrane.

[0008] The above technical solution involves opening several through holes on the surface of the flushing pipe, which facilitates water spraying to different locations and improves the cleaning effect.

[0009] As a further improvement to the above solution, the activated carbon fiber filter is located above the ultrafiltration membrane.

[0010] Through the above technical solutions, activated carbon fiber filters have a large adsorption capacity and a fast adsorption rate, which can effectively remove pigments and other impurities from raw materials and improve the decolorization effect. Ultrafiltration membranes can remove fine particles and other soluble impurities, thereby improving product quality.

[0011] As a further improvement to the above solution, the end of the air outlet pipe away from the hot air blower is connected to the tank body, and valves are installed inside both the discharge pipe and the slag discharge pipe.

[0012] The above technical solution involves blowing hot air into the air outlet pipe through a hot air blower, and then blowing hot air into the tank through the air outlet pipe to heat the raw materials, thereby improving the mixing and reaction efficiency. The wastewater after cleaning can be easily discharged through the slag discharge pipe.

[0013] As a further improvement to the above solution, the mixing component includes a motor, the output end of which is fixedly connected to a drive shaft, and a plurality of stirring blades are fixedly connected to the surface of the drive shaft.

[0014] The above technical solution uses a motor to drive the transmission shaft to rotate, which in turn causes several stirring blades to rotate, helping to mix the cyclodextrin raw material and decolorizing agent evenly and improving the decolorization effect.

[0015] As a further improvement to the above solution, the bottom of the motor is fixedly connected to the top of the tank.

[0016] As a further improvement to the above solution, the surface of the drive shaft is rotatably connected to the inner wall of the tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a flushing assembly. Specifically, by activating a cleaning pump, water is drawn from the pumping pipe and delivered into the flushing pipe via a delivery pipe. The water is then sprayed out through several through-holes in the flushing pipe, cleaning and regenerating the interior of the activated carbon fiber filter and ultrafiltration membrane, thus extending their service life. Furthermore, it eliminates the need for manual cleaning, making subsequent use more convenient.

[0018] This invention incorporates an inner tank, an activated carbon fiber filter, and a mixing assembly. Specifically, a motor drives a transmission shaft to rotate, causing several stirring blades to rotate, which helps to evenly mix the cyclodextrin raw material and the decolorizing agent. After initial decolorization, the cyclodextrin raw material inside the inner tank flows downward through the discharge pipe into the interior of the activated carbon fiber filter. The activated carbon fiber filter adsorbs the pigments in the raw material, achieving secondary decolorization and thus improving the decolorization effect. Attached Figure Description

The rinsing assembly 9 includes a fixing plate 901. A cleaning pump 902 is fixedly connected to the top of the fixing plate 901. A water suction pipe 903 is connected to the left end of the cleaning pump 902, and a water delivery pipe 904 is connected to the right end of the cleaning pump 902. One end of the water delivery pipe 904 extends to the tank 1 and is connected to a rinsing pipe 905. A second solenoid valve 906 is fixedly installed at the connection between the water delivery pipe 904 and the rinsing pipe 905. When the rinsing assembly 9 and the ultrafiltration membrane 11 need to be cleaned, the water suction pipe 903 is inserted into the tank. With an external water source, the second solenoid valve 906 is opened to connect the water supply pipe 904 with the flushing pipe 905, and the cleaning pump 902 is started. The cleaning pump 902 draws water through the water pumping pipe 903 and sends it into the flushing pipe 905 through the water supply pipe 904. The water is sprayed out through several through holes on the flushing pipe 905 to clean and regenerate the interior of the activated carbon fiber filter 8 and the ultrafiltration membrane 11, extending their service life. At the same time, no manual cleaning is required, which is convenient for subsequent use.

[0023] The top of the fixed plate 901 is fixedly connected to the bottom of the tank 1, and the surface of the flushing pipe 905 is fixedly connected to the inner wall of the activated carbon fiber filter 8 and the ultrafiltration membrane 11. Through the backwashing action of the flushing pipe 905, the impurities adsorbed on the activated carbon fiber filter 8 can be peeled off and carried away, thereby restoring part of its adsorption capacity.

[0024] The activated carbon fiber filter 8 is located above the ultrafiltration membrane 11. The cyclodextrin raw material inside the inner tank 5 flows downward into the interior of the activated carbon fiber filter 8 through the discharge pipe 6. The activated carbon fiber filter 8 adsorbs the pigments in the raw material, achieving secondary decolorization and thus improving the decolorization effect.

[0025] The end of the air outlet pipe 4 away from the hot air blower 3 is connected to the tank body 1. Valves are installed inside the discharge pipe 12 and the slag discharge pipe 14. The opening and closing of the discharge pipe 12 and the slag discharge pipe 14 are controlled by the valves.

[0026] The mixing component 13 includes a motor 1301, the output end of which is fixedly connected to a drive shaft 1302. Several stirring blades 1303 are fixedly connected to the surface of the drive shaft 1302. When the motor 1301 is started, it drives the drive shaft 1302 to rotate, which helps the cyclodextrin raw material and the decolorizing agent to mix evenly after initial decolorization.

[0027] The bottom of motor 1301 is fixedly connected to the top of tank 1.

[0028] The surface of the drive shaft 1302 is rotatably connected to the inner wall of the tank 1.

[0029] The implementation principle of the integrated ultrafiltration and decolorization device for cyclodextrin derivatives in this embodiment is as follows: First, the cyclodextrin raw material and decolorizing agent are added to the inner tank 5 through the feed pipe 2. Then, the hot air blower 3 is started, blowing hot air into the tank 1 through the air outlet pipe 4 to heat the inner tank 5, which helps accelerate the decolorization process. Next, the motor 1301 is started, driving the transmission shaft 1302 to rotate. This rotation of several stirring blades 1303 helps to evenly mix the cyclodextrin raw material and decolorizing agent. After initial decolorization, the first solenoid valve 7 is opened, allowing the cyclodextrin raw material inside the inner tank 5 to flow downwards through the discharge pipe 6 into the activated carbon fiber filter 8. The activated carbon fiber filter 8 adsorbs the pigments in the raw material, achieving secondary decolorization and improving the decolorization effect. The decolorized cyclodextrin raw material flows to the ultrafiltration membrane 11. Internally, impurities in the cyclodextrin raw material are filtered through the ultrafiltration membrane 11, improving product quality. The valve on the discharge pipe 12 is opened, and the processed cyclodextrin raw material is discharged through the discharge pipe 12. When it is necessary to clean the rinsing component 9 and the ultrafiltration membrane 11, the water pump 903 is placed into the external water source, the second solenoid valve 906 is opened, and the water supply pipe 904 is connected to the rinsing pipe 905. The cleaning pump 902 is started, and the cleaning pump 902 draws water through the water pump 903 and sends it into the interior of the rinsing pipe 905 through the water supply pipe 904. The water is sprayed out through several through holes on the rinsing pipe 905 to clean and regenerate the interior of the activated carbon fiber filter 8 and the ultrafiltration membrane 11, extending their service life. At the same time, no manual cleaning is required, which is convenient for subsequent use. The valve on the slag discharge pipe 14 is opened, so that the cleaning wastewater is discharged through the slag discharge pipe 14.
