Description

Technical Field

[0001] The utility model relates to the technical field of quercetin production equipment, in particular to a quercetin extraction and filtration integrated machine. Background Art

[0002] Quercetin, also known as quercetin, has antioxidant properties and can be used as a medicine. It has good expectorant and antitussive effects and can relieve asthma to a certain extent. In addition, it has the effects of lowering blood pressure, enhancing capillary resistance, reducing capillary fragility, lowering blood lipids, dilating coronary arteries, and increasing coronary blood flow. Quercetin has a wide range of sources and is widely found in the stems, bark, flowers, leaves, buds, seeds, and fruits of many plants. Its preparation method mainly involves heating an inorganic acid solution to boiling and then mixing it with rutin for hydrolysis. The hydrolyzed solution is then filtered to obtain a filter cake, which is washed with water until neutral and then dried to obtain crude quercetin. Finally, the quercetin in the crude product is dissolved and transferred using ethanol for purification. This process is very cumbersome and requires transfer between multiple devices, which increases the possibility of contamination. In addition, the acid solution used for hydrolyzing rutin needs to be prepared on-site using concentrated acid. The dilution process requires constant stirring, which is time-consuming, labor-intensive, and prone to danger. An integrated production equipment is needed to solve the above problems.

[0015] like Figure 1 and Figure 2 As shown, the quercetin extraction and filtration integrated machine includes a mixing kettle 1. A plurality of electric heaters 11 are spaced apart on the top and bottom sides of the mixing kettle 1. A heat dissipation hole 103 is provided between two adjacent electric heaters 11. A cooling water pipe can be inserted into the heat dissipation hole 103. The bottom surface of the output side of the mixing kettle 1 is hinged to the ground hinge seat 12. The output side opening is provided with a gate mesh assembly. The gate mesh assembly includes a gate plate 5. The gate plate 5 is vertically slidably connected to the gate plate slot provided on the top surface of the frame opening 102 on the output side of the mixing kettle 1. When the gate plate 5 falls, the bottom surface of the gate plate 5 is inserted into the sealing groove on the bottom surface of the frame opening 102. When the gate plate 5 is lifted, the upper side through hole 501 of the gate plate 5 can be aligned with the positioning screw hole 204 on the outer wall of the dilution kettle 2, and a positioning bolt can be screwed in to fix it. The end face flange of the frame opening 102 is connected to the filter cover 6.

[0016] In this embodiment, a feed shovel 101 is provided on the input side of the mixing kettle 1. This shovel 101 has a gate structure similar to the gate plate 5. Below the feed shovel 101 is a kettle-lifting cylinder 3 with a downward-facing piston rod. The lower end of the piston rod of the kettle-lifting cylinder 3 is rotatably connected to a roller 301. A concentric dilution kettle 2 is provided on the top surface of the mixing kettle 1. The top surface of the dilution kettle 2's opening is connected to the bottom surface of the top cover 203 via a number of struts 205. A valve post 201 is provided at the center of the bottom surface of the dilution kettle 2. A control valve 202, which opens into its inner cavity, is provided around the underside of the valve post 201. A stirring motor 4 is provided at the center of the top cover 203 of the dilution kettle 2. The output rod of the stirring motor 4 extends vertically downward through the valve post 201 into the mixing kettle 1. A stirring assembly is provided on the output rod.

[0017] In this embodiment, the stirring assembly includes a stirring rake 7, the center of which is connected to the bottom of the output rod of the stirring motor 4. Symmetrical teeth 701 are located on either side of the rake. The output rod of the stirring motor 4 is connected to the center of a beam 8, which is located above the valve column 201. The beam 8 is symmetrically equipped with several stirring rods 801 pointing vertically downward. One side of the dilution kettle 2 is connected to the outlet of the feed pipe 9 in the feed assembly. The feed pipe 9 is equipped with a regulating valve 901. The input end of the feed pipe 9 is connected upward to the bottom outlet of the feed hopper 10.

[0018] The working principle of this utility model is as follows:

[0019] Appropriate amounts of clean water and inorganic acid (preferably hydrochloric acid or concentrated sulfuric acid) are respectively injected into the dilution kettle 2 and the feed hopper 10. The stirring motor 4 is started to drive the stirring assembly for stirring. The regulating valve 901 is gradually opened to release the inorganic acid into the dilution kettle 2. When the inorganic acid solution is evenly diluted, the control valve 202 is opened, and the inorganic acid solution is sprayed through the inner cavity of the valve column 201 onto the raked rutin in the mixing kettle 1. The electric heater 11 is started to perform mixed heating. When the rutin is completely hydrolyzed, the electric heater 11 is turned off, and a cooling water pipe is inserted into the heat dissipation through-hole 103 for cooling. When the hydrolyzed solution cools to 60-65 degrees Celsius, the kettle cylinder 3 is started to lift one side of the device, and the gate plate 5 is pulled upward to filter. The warm water filter cake is blocked in the kettle by the filter cover 6. Add clean water into the kettle from the feed shovel 101 to continue washing the filter cake until it is neutral, then reset the top kettle cylinder 3, close the gate 5, start the electric heater 11 again to dry the filter cake to obtain crude quercetin, then add alcohol to the kettle to absorb the quercetin in the filter cake, start the top kettle cylinder 3 again to filter, collect the filtrate for evaporation and crystallization to obtain fine quercetin.

[0020] The utility model completes the acid adjustment and stirring operations in the dilution kettle 2 and the mixing kettle 1 through a stirring motor 4. The prepared acid solution is directly put into the mixing kettle 1 to be heated and mixed with rutin. When quercetin is generated, the top kettle cylinder 3 can lift one side of the device to assist in multiple cleaning, filtration, dissolution and transfer of the filter cake containing quercetin, which is convenient and efficient.
