Description

Technical Field

[0001] The utility model relates to the technical field of macroporous resin regeneration, in particular to a macroporous resin regeneration processing device for Panax notoginseng extraction. Background Art

[0002] The main active ingredient of Panax notoginseng is total saponins, which are used to prevent and treat cardiovascular and cerebrovascular diseases such as hyperlipidemia, hypertension, atherosclerosis, myocardial ischemia, and ischemic stroke. Total saponins are primarily extracted from Panax notoginseng medicinal materials. The extraction method includes drying and crushing the Panax notoginseng, ethanol extraction, ethanol recovery under reduced pressure, adsorption, ethanol elution, ethanol recovery under reduced pressure, decolorization, concentration, and drying. Macroporous resins are used in the extraction and adsorption of Panax notoginseng's active ingredients. Macroporous resins are a type of polymeric adsorption resin with a macroporous structure that does not contain exchange groups. They possess a well-defined macroporous network structure and a large specific surface area, allowing them to selectively physically adsorb organic matter from aqueous solutions. After a period of use, the adsorption capacity of macroporous resins decreases. To ensure optimal extraction of Panax notoginseng's active ingredients, they must be regenerated after a period of use before continued use.

[0003] Currently, the following problems exist when regenerating macroporous resins: First, there is the problem of incomplete cleaning of the macroporous resin and poor regeneration effect, which affects the normal use of the macroporous resin in the future; second, during the cleaning process, the traditional method uses a long soaking method, which is time-consuming and has low cleaning efficiency. In order to improve efficiency, stirring or vibration is often used to promote contact between the macroporous resin and the cleaning solution. However, due to the fragility of macroporous resin, this process will cause a lot of macroporous resin to break, resulting in loss and waste of macroporous resin, and increasing the cost of using macroporous resin. Therefore, it is an objective need to develop a regeneration and processing device for macroporous resin for Panax notoginseng extraction that can thoroughly clean, regenerate efficiently, and not easily break.

[0012] Furthermore, a rubber layer is provided on the inner walls of the vertical cylinder and the rectangular vertical groove.

[0013] Furthermore, vertical spoiler plates are provided on the inner wall of the tank.

[0014] When the utility model is in operation, an appropriate amount of cleaning liquid is first introduced into the tank body from the liquid inlet. The cleaning liquid can be selected from clean water, acid, alkali liquid and ethanol as needed. Then the motor is started, and the cleaning liquid enters the rectangular vertical groove and the vertical cylinder from the through hole. The motor drives the bottom plate, vertical cylinder, rectangular vertical groove, circular plate and rectangular plate to rotate synchronously, and the macroporous resin that needs to be regenerated is introduced into the tank body from the feed port, falls into the vertical cylinder through the blanking channel, and rotates accordingly.

The cleaning liquid is in a state of continuous flow and has a certain impact and stirring effect on the macroporous resin. It can continuously turn over the macroporous resin and quickly take away the impurities adsorbed in the macroporous resin, thereby realizing the cleaning and regeneration of the macroporous resin. The cleaning is more thorough and the regeneration effect is better, ensuring the normal use of the macroporous resin in the future as much as possible; secondly, in view of the characteristic that the macroporous resin will float in the cleaning liquid, the device can use the cylinder to drive the circular plate and the rectangular plate to press downward during the regeneration process of the macroporous resin, press the macroporous resin into the cleaning liquid, and then lift the circular plate and the rectangular plate back, and the macroporous resin The resin then floats up, and this process is repeated continuously, which can make the macroporous resin float in the cleaning liquid, thereby turning the macroporous resin over, making the macroporous resin in a state of motion, and improving the cleaning efficiency and regeneration effect of the macroporous resin; in addition, compared with the long-term immersion method used in the traditional method, the cleaning liquid and the macroporous resin in this device are in a relative motion state, which is conducive to shortening the cleaning time and improving the cleaning efficiency. At the same time, the stirring or vibration method is eliminated, and the method of using a vertical cylinder and a rectangular vertical groove to drive the macroporous resin to rotate, and the method of using a circular plate and a rectangular plate to press down the macroporous resin, on the premise of achieving efficient cleaning and regeneration, promotes the method of promoting full contact between the macroporous resin and the cleaning liquid in a more gentle way, which can reduce the probability and possibility of macroporous resin fragmentation, reduce the loss and waste of macroporous resin, ensure the integrity of the macroporous resin during the regeneration process, and thus reduce the cost of using the macroporous resin. In summary, the utility model has the advantages of thorough cleaning, high regeneration efficiency, and not easy to fragment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or improvements based on the present invention fall within the scope of protection of the present invention.

[0020] like Figures 1 to 3 As shown, the utility model includes a tank body 1 and a feed port 11, a liquid inlet is provided on the tank body 1, a vertical cylinder 2 is concentrically provided in the tank body 1, a plurality of rectangular vertical grooves 3 are evenly distributed on the circumference of the outer wall of the vertical cylinder 2, the rectangular vertical grooves 3 are connected to the vertical cylinder 2, and a plurality of through holes are processed on both sides of the rectangular vertical groove 3. The size of the through hole is determined according to the particle size of the macroporous resin to ensure that the size of the through hole is smaller than the macroporous resin. A bottom plate 4 is provided at the bottom of the vertical cylinder 2 and the rectangular vertical groove 3. A motor 5 is installed at the bottom of the tank body 1. The output shaft of the motor 5 is inserted into the tank body 1 and is connected to the bottom The center of the plate 4 is fixedly connected, a circular plate 6 is provided at the upper portion of the vertical cylinder 2, a cylinder 7 is installed at the top of the tank body 1, the piston rod of the cylinder 7 is rotatably connected to the center of the circular plate 6, a plurality of rectangular plates 8 are provided around the circular plate 6, the edges of the rectangular plates 8 match the inner walls of the corresponding rectangular vertical slots 3, the circular plates 6 and the rectangular plates 8 are connected by a connecting rod 9, and an annular blanking channel 10 is provided between the circular plate 6 and the rectangular plates 8. The blanking channel 10 is an annular structure that ensures that the macroporous resin introduced from the feed port 11 can smoothly enter the blanking channel 10. When the utility model is in operation, the motor 5 can be rotated forward and reversed, so that the vertical cylinder 2 and the rectangular vertical slot 3 rotate forward for a period of time and then reverse for a period of time, thereby improving the stirring effect of the macroporous resin and improving the regeneration efficiency of the macroporous resin.

[0021] The feed port 11 is located at the top of the tank body 1 above the material drop channel 10, and a discharge pipe is provided at the bottom of the tank body 1. The motor 5 and the cylinder 7 are existing equipment and can be purchased, installed and used on the market according to actual parameters.

[0022] When the utility model is in operation, an appropriate amount of cleaning liquid is first introduced into the tank body 1 from the liquid inlet. The cleaning liquid can be selected from clean water, acid, alkali liquid and ethanol as needed. Then the motor 5 is started, and the cleaning liquid enters the rectangular vertical groove 3 and the interior of the vertical cylinder 2 from the through hole. The motor 5 drives the bottom plate 4, the vertical cylinder 2, the rectangular vertical groove 3, the circular plate 6 and the rectangular plate 8 to rotate synchronously, and the macroporous resin that needs to be regenerated is introduced into the tank body 1 from the feed port, falls into the interior of the vertical cylinder 2 through the blanking channel 10, and rotates therewith. It spreads to the surroundings under the action of centrifugal force and gradually enters each rectangular vertical groove 3. At this time, the cleaning liquid enters it from the through hole on one side of the rectangular vertical groove 3 and is then discharged from the through hole on the other side. In this process, the cleaning liquid contacts the macroporous resin during the flow, and because the cleaning liquid has a certain impact force, it can continuously penetrate into the interior of the macroporous resin, thereby realizing the cleaning and regeneration of the macroporous resin. In the present invention, the macroporous resin is first introduced into the vertical cylinder 2, and then enters the rectangular vertical groove 3 under the action of centrifugal force. At this time, the macroporous resin forms a vertical wall in the rectangular vertical groove 3. When the vertical wall rotates, it pushes the cleaning liquid in the tank body 1, and the cleaning liquid close to the vertical wall will enter the rectangular vertical groove 3 from the through hole to clean the macroporous resin. The cleaning liquid is in a state of continuous flow and has a certain impact and stirring effect on the macroporous resin. It can continuously turn over the macroporous resin and quickly take away the impurities adsorbed in the macroporous resin, thereby realizing the cleaning and regeneration of the macroporous resin. The cleaning is more thorough and the regeneration effect is better, ensuring the subsequent normal use of the macroporous resin as much as possible; secondly, in view of the characteristic that the macroporous resin will float in the cleaning liquid, during the process of regenerating the macroporous resin, the cylinder 7 can drive the circular plate 6 and the rectangular plate 8 to press downward, press the macroporous resin into the cleaning liquid, and then lift the circular plate 6 and the rectangular plate 8 back up. , the macroporous resin floats up, and this process is repeated continuously, which can make the macroporous resin float in the cleaning liquid, thereby turning over the macroporous resin, making the macroporous resin in a state of motion, and improving the cleaning efficiency and regeneration effect of the macroporous resin; in addition, compared with the traditional method of using a long time of immersion, the cleaning liquid and the macroporous resin in this device are in a relative motion state, which is conducive to shortening the cleaning time and improving the cleaning efficiency. At the same time, the stirring or vibration method is eliminated, and the vertical cylinder 2 and the rectangular vertical groove 3 are used to drive the macroporous resin to rotate, and the circular plate 6 and the rectangular plate 8 are used to press down the macroporous resin. Under the premise of achieving efficient cleaning and regeneration, the method of promoting full contact between the macroporous resin and the cleaning liquid is more gentle, which can reduce the probability and possibility of macroporous resin fragmentation, reduce the loss and waste of macroporous resin, ensure the integrity of the macroporous resin during the regeneration process, and thus reduce the cost of using macroporous resin.

[0023] A solid-liquid separator 12, a dryer 13 and a sieving machine 14 are sequentially arranged on the discharge pipe. The solid-liquid separator 12, the dryer 13 and the sieving machine 14 are all existing equipment. The solid-liquid separator 12 is used to separate the macroporous resin and the cleaning liquid, the dryer 13 is used to dry the macroporous resin, and the sieving machine 14 is used to screen the macroporous resin and separate out debris and fine impurities.

[0024] The output shaft of the motor 5 and the base plate 4 are connected via a flange 15. In order to facilitate the disassembly and assembly between the output shaft of the motor 5 and the base plate 4, the flange 15 is used for connection. In actual use, other structural connection structures can also be used according to actual conditions.

[0025] A guide tube 16 is obliquely provided on the through hole of the rectangular vertical groove 3. The lower end of the guide tube 16 is connected to the through hole. The guide tube 16 rotates synchronously with the rectangular vertical groove 3. The cleaning liquid enters the guide tube 16 from the higher end and then enters the rectangular vertical groove 3 from the lower end. The water flow is in a state of oblique downward flow, which can impact the macroporous resin while causing the macroporous resin to sink to the lower part of the cleaning liquid, and then float up under the action of buoyancy. This process is repeated continuously, which can promote the cleaning and regeneration effect of the macroporous resin.

[0026] A discharge pipe 17 is provided on the side wall at the bottom of the rectangular vertical groove 3, and a gate valve is provided on the discharge pipe 17. After the macroporous resin is cleaned and regenerated, the discharge pipe 17 is provided to facilitate its discharge. The macroporous resin is first pressed down by the circular plate 6 and the rectangular plate 8, and the gate valve is opened. Under the action of centrifugal force, the macroporous resin is discharged from the discharge pipe 17 and finally discharged through the discharge pipe.

[0027] A scraper 18 is provided on the output shaft of the motor 5. The lower end surface of the scraper 18 contacts the bottom of the tank body 1. The scraper 18 can scrape away the impurities deposited on the bottom of the tank body 1 and discharge them from the discharge pipe along with the cleaning liquid. At the same time, when the macroporous resin is discharged from the bottom of the rectangular vertical groove 3, the macroporous resin falls to the bottom of the tank body 1. The scraper 18 can also stir the macroporous resin, further improving the cleaning effect of the macroporous resin. In order to prevent the scraper 18 from crushing the macroporous resin, the surface of the scraper 18 can be wrapped with a layer of rubber material.

[0028] The base plate 4 is machined with several air holes. An air distributor 19 is located within the tank body 1 below the base plate 4. An air pipe 20 is provided on the tank body 1, connected to the air distributor 19. The air distributor 19 is a conventional device that evenly distributes air across the cross-section of the tank body 1. Air is sprayed from the air distributor 19 into the cleaning liquid, forming a number of tiny bubbles. These bubbles then pass through the air holes and enter the rectangular vertical slots 2 and vertical cylinder 2. As they rise, they agitate the macroporous resin, enhancing its regeneration. When ethanol is used as the cleaning liquid, cold air can be introduced into the air pipe 20. This cool air absorbs heat from the ethanol and the macroporous resin, lowering their temperatures and achieving a cooling effect.

[0029] A rubber layer 21 is provided on the inner walls of the vertical cylinder 2 and the rectangular vertical groove 3. The macroporous resin is relatively fragile. If it directly collides with the inner walls of the vertical cylinder 2 and the rectangular vertical groove 3, it is easy to break, resulting in waste of the macroporous resin. After the rubber layer 21 is provided, since the rubber layer 21 has a certain degree of flexibility and elasticity, it can play a buffering role, thereby reducing the possibility of the macroporous resin breaking.

[0030] A spoiler vertical plate 22 is provided on the inner wall of the tank body 1. When the device is in operation, the motor 5 drives the vertical cylinder 2 and the rectangular vertical groove 3 to rotate, and drives the cleaning liquid to rotate. The flow rate of the cleaning liquid will continue to increase, and eventually approach the rotation speed of the rectangular vertical groove 3. At this time, less cleaning liquid will enter the rectangular vertical groove 3, and the cleaning efficiency of the macroporous resin will be reduced. In order to improve this situation, a spoiler vertical plate 22 is provided. When the cleaning liquid flows onto the spoiler vertical plate 22, it is blocked by the spoiler vertical plate 22, and the flow direction and flow rate of part of the cleaning liquid change, which in turn affects the surrounding cleaning liquid and generates turbulence, thereby preventing the swirl flow rate of the cleaning liquid from being close to the rotation speed of the rectangular vertical groove 3, thereby ensuring the cleaning efficiency of the macroporous resin.
