Description

Technical Field

[0001] The invention belongs to the technical field of traditional Chinese medicine processing, and particularly relates to a traditional Chinese medicine extract storage tank with a filtering device and a use method thereof. Background Art

[0002] In the process of processing traditional Chinese medicine, it is necessary to first control the drying of the medicinal materials, and then stir-fry, grind, soak and prepare them. The soaking is to extract the effective ingredients from the medicinal materials by soaking, reflux extraction and other methods to prepare Chinese medicine extracts. During the soaking process, the Chinese medicine at different liquid levels needs to be discharged.

[0003] At present, there is a sedimentation tank with the existing announcement number CN217340201U, which includes a tank body, a feed port is provided on the top of the tank body, a discharge port is provided on the bottom of the tank body, a discharge bin is connected to the discharge port, the discharge bin includes a discharge barrel and a tank bottom valve, and a filter plate is provided between the discharge barrel and the tank bottom valve. The utility model has a simple structure, and creatively adds a detachable discharge bin, a filter plate is provided in the discharge bin, and the precipitate can be filtered by the filter plate of the discharge bin. For easy-to-filter granular precipitates, after the alcohol precipitation is completed, there is no need to stand and wait for stratification, and the liquid can be directly drained through the tank bottom valve, and the liquid can be repeatedly added to complete the washing process, which greatly improves the efficiency of precipitation washing.

[0004] But there is also a problem: the mechanism cannot adjust the position of the suction pipe, and the filter plate is used for filtering, which easily causes the filter plate to be blocked. Summary of the invention

[0005] This solution provides a Chinese medicine extract storage tank with a filtering device, including: Liquid storage tank: The liquid storage tank is provided with a liquid storage tank feed port, a liquid storage tank discharge port and a manhole; Suction pipe: the suction pipe is matched with the liquid storage tank; The suction pipe is L-shaped and is located in the middle of the liquid storage tank; It also includes a suction pipe rotating mechanism: the suction pipe rotating mechanism includes: Steering column: the steering column is rotatably connected to the liquid storage tank; Steering wheel: the steering wheel is fixedly connected to the steering column; Driving gear: The driving gear is fixedly connected to the steering column coaxially; Driven gear: The driven gear is fixedly connected to the suction pipe coaxially, and the driven gear is meshed with the driving gear.

[0006] The principle of this scheme is that the Chinese medicine extract enters the liquid storage tank through the liquid storage tank feed port for temporary storage. During the temporary storage, some precipitation will be generated. These precipitations gather at the bottom, and the extract is divided into two parts: supernatant and precipitation. When concentrating, the supernatant is first extracted through the suction pipe for concentration, and the position of the suction pipe is adjusted by the steering wheel of the discharge device. The operator turns the steering wheel to rotate the steering column, and the rotation of the steering column drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, and the driven gear drives the suction pipe to rotate. While adjusting the position, observe the distance between the suction port and the precipitation liquid surface through the manhole. When the suction port is close to the precipitation liquid surface, stop sucking and complete the separation of the supernatant.

[0007] The beneficial effect of this solution is that the position of the suction pipe can be adjusted by the steering wheel, so that the supernatant can be extracted more thoroughly, and at the same time, the suction pipe can be prevented from extracting the sediment part.

[0008] Furthermore, it also includes a centrifuge, which includes a motor, a feeding pump, a differential, a drum, and a screw. The drum is provided with a centrifuge liquid outlet and a centrifuge slag outlet. The shaft of the motor is fixedly connected to the drum, and the shaft of the motor is fixedly connected to the screw through the differential. The screw cooperates with the drum, and a centrifuge feed port is provided inside the screw. The centrifuge feed port is connected to the liquid storage tank discharge port through the feeding pump.

[0009] Generally speaking, when separation is performed by sedimentation and stratification, part of the liquid medicine accumulates on the sediment, which causes waste. In this solution, the spiral is located inside the drum, and the spiral is coaxially rotated with the drum. An opening is provided in the middle of the spiral, which is connected to the inside of the drum. An auger plate is provided outside the spiral, and the auger plate cooperates with the inside of the drum.

[0010] When the upper clear liquid is extracted, the operator starts the motor to rotate the drum, and then the differential makes the screw rotate in the same direction. The speed of the screw is lower than that of the drum. When the speed is stable, the feed pump starts to extract the lower sediment, so that the sediment is evenly fed into the centrifuge feed port, and the sediment enters the inside of the screw. Under the action of centrifugation, the sediment flows out from the opening, and then centrifuges. Under the action of the auger plate, the sediment flows out from the centrifuge slag outlet, and the liquid flows out from the centrifuge outlet through overflow, completing the secondary separation.

[0011] This mechanism performs secondary separation on the precipitate, so that the liquid medicine accumulated on the precipitate is also collected, thereby improving the separation quality.

[0012] Furthermore, a pump is also included, and the pump is communicated with the material suction pipe. The pump can be used to suck materials faster, thereby improving efficiency.

[0013] Furthermore, it also includes a concentrator, the liquid outlet and the suction pipe of the centrifuge are connected to the concentrator through a pump, and valves are provided at the connection points between the liquid outlet and the suction pipe of the centrifuge and the pump. The liquid medicine obtained by the primary separation of the liquid storage tank and the liquid medicine obtained by the secondary separation of the centrifuge are sent to the concentrator, and the concentrator performs solid-liquid separation to evaporate most of the solvent in the liquid medicine. This mechanism can perform solid-liquid separation on the liquid medicine again, greatly improving the concentration of the liquid medicine.

[0014] Furthermore, it also includes a cleaning mechanism, which includes a nozzle, a connecting pipe and an energy storage mechanism. The nozzle is located inside the liquid storage tank and is fixedly connected to the liquid storage tank. The energy storage mechanism is used to store kinetic energy and supernatant. The nozzle and the energy storage mechanism are connected through a connecting pipe, and the nozzle cooperates with the energy storage mechanism.

[0015] When extracting sediment, many sediments will adhere to the inner wall of the liquid storage tank, resulting in some sediments not entering the centrifuge for secondary separation. In this mechanism, when the liquid level gauge shows that the extraction is completed, the operator controls the electric valve to open, and then the previously stored supernatant is sprayed out from the nozzle through the energy storage mechanism. The sprayed liquid slides with the sediment adhered to the inner wall and is pumped away by the feed pump. This mechanism can send all the sediments on the inner wall into the centrifuge. The existing ones generally use the nozzle to spray water to wash them off. This mechanism uses the previously extracted supernatant to wash them off. Compared with the existing ones, this mechanism can maintain the original concentration of the liquid medicine and will not consume the concentration of the liquid medicine.

[0016] Further, the energy storage mechanism includes a storage box, a return spring, a sliding ring, and a piston block, the storage box is connected to the extraction pipe of the pump, the storage box is connected to the connecting pipe, the piston block is connected to the storage box in a sliding and sealing manner, and the piston block is provided with a one-way valve, one end of the return spring is fixedly connected to the storage box, and the other end is fixedly connected to the piston block; The sliding ring is slidably connected to the extraction tube, and the sliding ring is provided with a through hole for allowing liquid to pass through. One end of the steel wire is fixedly connected to the sliding ring, and the other end is fixedly connected to the piston block.

[0017] In the initial state, the piston block is located at the lower part of the storage box under the action of the torque spring.

[0018] When the pump extracts the supernatant, the liquid will be sent into the concentrator from the extraction pipe through the pump. When the liquid passes through the extraction pipe, the liquid will impact the sliding ring, and the sliding ring will move. The movement of the sliding ring will drive the piston block to move upward. When the piston block moves upward, the liquid will enter the bottom of the piston block through the one-way valve, and the storage box completes the storage of energy.

[0019] When the extraction tube has finished extracting the liquid, there is no liquid in the extraction tube at this time, and the piston block returns to its position under the action of the reset spring, and at the same time drives the sliding ring to return to its position. At this time, due to the return of the piston block, the liquid is squeezed out from the connecting tube. At this time, the liquid in the storage box is sent to the nozzle under the pressure of the reset spring, and the nozzle sprays the liquid to take away the sediment adhering to the inner wall. This mechanism saves costs by automatically storing liquid medicine and storing energy when extracting the supernatant.

[0020] The present invention also provides a method for using a Chinese medicine extract storage tank with a filtering device, comprising the following steps: Step S10: The liquid storage tank outlet and the centrifuge feed port connected; the centrifuge outlet and the turnover tank feed port connected; Step S20: Before use, check whether all facilities and instruments are in good condition, whether the cleaning status meets the requirements, and whether the suction port of the supernatant storage pipe is at the highest point; Step S30: Open the feed inlet valve to feed, and close the feed valve after the feeding is completed; start the pump to extract the supernatant to the concentrator for concentration; Step S40: During the extraction of the supernatant, the position is adjusted by observing the change of the liquid level meter, and the distance between the suction port and the sedimentation liquid surface is observed through the manhole. When the suction port is close to the sedimentation liquid surface, the suction is stopped, and the valve after the pump, the pump, and the valve before the pump are closed successively; Step S50: Start the centrifuge, open the valve from the outlet of the liquid storage tank to the feed inlet of the centrifuge, and start filtering. After the filtering is completed, turn off the centrifuge and close the corresponding valve to complete the secondary filtering.

[0021] The beneficial effects of this method are: 1. Prolonging the service life of the equipment. Reducing the impact of precipitated impurities on subsequent processes, reducing or avoiding the blockage or sticking of pipes, valves, and connectors, resulting in unsmooth liquid discharge, improving work efficiency, reducing equipment load, and extending the service life of the equipment; 2. Improve product yield. Reduce waste and process material sticking to the wall, turn waste into treasure, and improve product yield. Calculated based on 7.5 tons of liquid medicine in an 8-ton storage tank, there is about 400L of sediment at the bottom, and the filter residue is about 5-30kg, depending on the product situation. Calculated based on 370L of filtrate, it accounts for about 5% of the total liquid medicine. If it is treated as waste liquid, it is equivalent to wasting 5% (excluding the loss caused by material sticking to the wall and blockage).

[0022] 3. Improve product quality. Improve the impact of precipitated impurities on product taste, appearance and other quality aspects.

[0023] 4. Environmental protection: energy saving and emission reduction. Reducing the amount of waste liquid, reducing the amount of waste liquid treatment, and saving the corresponding environmental protection treatment costs. BRIEF DESCRIPTION OF THE DRAWINGS

The breathing port 29 is used to balance the internal pressure and release excess gas. The venting port 30 is used to discharge liquid when cleaning the liquid storage tank. The CIP port 5 facilitates the CIP system to automatically clean the liquid storage tank. The manhole 7 is a large opening 28 on the liquid storage tank, which is usually used to provide a channel for personnel to enter the equipment for inspection, maintenance, cleaning or installation. The spare hole 32 is used for backup. When other holes are blocked, the spare hole 32 can be used.

[0027] The lower end cap is provided with a liquid storage tank discharge port 13; the lower end cap 12 is connected to a second sewage outlet 20, which can discharge the cleaning liquid. A liquid level gauge 2 is provided at the body 1 of the liquid storage tank, and an operating platform 8 is also provided at the body 1 of the liquid storage tank. The operating platform 8 is electrically connected to the pump 18, the motor and the feed pump. The suction pipe 27 is L-shaped, one end of the suction pipe 27 is located inside the liquid storage tank, called the supernatant suction port 26, and the other end is connected to the pump 18 through a rotary joint; and the suction pipe 27 is located in the lower middle part of the liquid storage tank.

[0028] It also includes a suction pipe rotating mechanism 10: the suction pipe rotating mechanism 10 includes: a steering column 9: the steering column 9 is rotatably connected to the liquid storage tank; a steering wheel 6: the steering wheel 6 is fixedly connected to the steering column 9; a driving gear 47: the driving gear 47 is coaxially fixedly connected to the steering column 9; a driven gear 48: the driven gear 48 is coaxially fixedly connected to the suction pipe 27, and the driven gear 48 is meshed with the driving gear 47.

[0029] As attached Figure 1 , Figure 2 As shown: It also includes a filtration system: a horizontal centrifuge and a turnover box (including a respirator 15).

[0030] The centrifuge includes a motor, a feed pump, a differential 35, a drum 33, and a screw 34. The drum 33 is provided with a centrifuge liquid outlet 23 and a centrifuge slag outlet 25. The shaft of the motor is fixedly connected to the drum 33, and the shaft of the motor is fixedly connected to the screw 34 through the differential 35. The screw 34 cooperates with the drum 33. The screw 34 is provided with a centrifuge feed port 21 inside, and the centrifuge feed port 21 is connected to the lower head of the liquid storage tank discharge port 12; 13 through the feed pump. The screw 34 is located inside the drum 33, and the screw 34 and the drum 33 are coaxially arranged for rotation. An opening 28 is provided in the middle of the screw 34, and the opening 28 is connected to the inside of the drum 33. A auger plate is provided outside the screw 34.

[0031] The centrifuge liquid outlet 23 is connected to a turnover tank 16 through a high-pressure hose 22. The turnover tank 16 is used to temporarily store the liquid medicine separated from the centrifuge. The turnover tank 16 is provided with a first sewage outlet 19 for discharging the sewage during cleaning. A slag receiving pan 24 is placed at the bottom of the centrifuge slag outlet 25 for placing sediment.

[0032] The centrifuge is a horizontal centrifuge (it can also be a vertical centrifuge or an ordinary funnel filter. The purpose of setting the horizontal type is to consider the height of the liquid storage tank from the ground and the ease of operation. The horizontal centrifuge can be fed by gravity, and the vertical type needs a pump to pump the material from the liquid storage tank to the centrifuge; the ordinary funnel filter can also filter, but it also needs the help of a pump or vacuum to transport the material. At the same time, the filter paper or filter bag is replaced and the slag is removed frequently, and the filtration efficiency is not high).

[0033] The centrifuge liquid outlet 23 and the suction pipe 27 are both connected to the concentrator through the pump 18, and valves 17 are provided at the connection points between the centrifuge liquid outlet 23 and the suction pipe 27 and the pump 18. The liquid medicine obtained by the primary separation in the liquid storage tank and the liquid medicine obtained by the secondary separation in the centrifuge are sent to the concentrator, which performs solid-liquid separation and evaporates most of the solvent in the liquid medicine, thereby achieving solid-liquid separation.

[0034] As attached Figure 4 , Figure 5 , Figure 6 As shown: It also includes a cleaning mechanism, which includes a nozzle 36, a connecting pipe 37 and an energy storage mechanism 39. The nozzle 36 is located inside the liquid storage tank and is fixedly connected to the liquid storage tank. The energy storage mechanism 39 is used to store kinetic energy and supernatant.

[0035] The energy storage mechanism 39 includes a storage box 40, a return spring 41, a sliding ring 42, and a piston block 43. The storage box 40 is connected to the extraction pipe 46 of the pump 18, and the storage box 40 is connected to the connecting pipe 37. The piston block 43 is slidingly and sealingly connected to the storage box 40, and the piston block 43 is provided with a one-way valve 44 that can only conduct from the extraction pipe 46 to the storage box 40. One end of the return spring 41 is fixedly connected to the storage box 40, and the other end is fixedly connected to the piston block 43; the connecting pipe 37 is provided with a one-way valve from the storage box 40 to the nozzle 36.

[0036] The sliding ring 42 is slidably connected to the extraction pipe 46. The sliding ring 42 is provided with a through port for allowing liquid to pass through. One end of the steel wire 38 is fixedly connected to the sliding ring 42, and the other end is fixedly connected to the piston block 43. The sliding ring 42 can also be replaced by a stressed filter plate. When the extraction pipe 46 is closed, a water hammer effect generally occurs. The water hammer effect refers to the pressure fluctuation phenomenon generated in the pipeline when the fluid flow rate changes rapidly due to the sudden closure of the valve or the stop of the pump in the fluid transmission system. This phenomenon may cause a significant increase in pressure, thereby causing damage to the pipeline system. The water hammer effect may cause mechanical damage or even rupture of pipelines, joints, flanges and other accessories. The stressed filter plate or sliding ring 42 in this solution can play a buffering role and reduce the intensity of the water hammer effect.

[0037] The storage box 40 is provided with a pulley block, and the steel wire 38 is connected to the sliding ring 42 through the pulley block.

[0038] The energy storage mechanism may be positioned above the nozzle 36, so that even if there is residual liquid, it will flow into the nozzle 36 due to gravity, and thus no concentrated liquid will remain in the energy storage mechanism.

[0039] In the initial state, the piston block 43 is located at the lower part of the storage box 40 under the action of the torque spring. When the sliding ring 42 pulls the piston block 43 upward, the liquid passes through the one-way valve 44, so that the liquid can enter the bottom of the piston block 43. When the return spring 41 moves back, the liquid will not flow back into the extraction pipe 46 due to the one-way valve 44.

[0040] As attached Figure 1-6 As shown: The principle of this scheme is that the Chinese medicine extract enters the liquid storage tank through the liquid storage tank feed port 4 for temporary storage. During the temporary storage, some precipitation will be produced. These precipitations gather at the bottom, and the extract is divided into two parts: supernatant and precipitation. When concentrating, the supernatant is first extracted through the suction pipe 27 for concentration, and the position of the suction pipe 27 is adjusted by the steering wheel 6 of the discharge device. The operator turns the steering wheel 6 to rotate the steering column 9. The rotation of the steering column 9 drives the driving gear 47 to rotate, and the driving gear 47 drives the driven gear 48 to rotate. The driven gear 48 drives the suction pipe 27 to rotate. While adjusting the position, observe the distance between the suction port and the precipitation liquid surface through the manhole 7.

[0041] When the liquid medicine passes through the extraction tube 46, the liquid will impact the sliding ring 42, and the sliding ring 42 will move. The movement of the sliding ring 42 will drive the piston block 43 to move upward. When the piston block 43 moves upward, the liquid will enter under the piston block 43, and the storage box 40 completes the storage of energy. When the suction port approaches the sedimentation liquid surface, the suction is stopped and the pump 18 is turned off.

[0042] When the extraction tube 46 has finished extracting the liquid, there is no liquid in the extraction tube 46, and the piston block 43 returns to its original position under the action of the return spring 41, and at the same time drives the sliding ring 42 to return to its original position. At this time, due to the return of the piston block 43, the liquid is squeezed out from the connecting tube 37. At this time, the liquid medicine in the storage box 40 is sent to the nozzle under the pressure of the return spring 41, and the nozzle sprays the liquid medicine to take away the precipitation adhering to the inner wall.

[0043] Then the operator starts the motor to rotate the drum 33, and then the screw 34 is rotated in the same direction through the differential 35. The speed of the screw 34 is lower than that of the drum 33. When the speed is stable, the feed pump starts to extract the lower layer of sediment, so that the sediment is evenly fed into the centrifuge feed port 21, and the sediment enters the inside of the screw 34. Under the action of centrifugation, the sediment flows out from the opening 28, and then centrifuges. Under the action of the auger plate, the sediment flows out from the centrifuge slag outlet 25, and the liquid flows out from the centrifuge liquid outlet 23 through overflow for secondary separation.

[0044] Finally, the liquid medicine obtained from the first separation in the liquid storage tank and the liquid medicine obtained from the second separation in the centrifuge are sent to the concentrator, which performs solid-liquid separation and concentrates the solid particles suspended in the liquid, thereby achieving solid-liquid separation. This mechanism can perform solid-liquid separation on the liquid medicine again, greatly improving the purity of the liquid medicine.

[0045] The beneficial effects of this solution are as follows: 1. This solution can adjust the position of the suction pipe 27 through the steering wheel 6, so that the supernatant can be extracted more thoroughly, and at the same time, it can prevent the suction pipe 27 from extracting the sediment. 2. This mechanism performs secondary separation on the sediment, so that the liquid medicine attached to the sediment is also collected, improving the separation quality. 3. This mechanism uses the previously extracted supernatant to flush, and compared with the existing mechanism, this mechanism can maintain the original concentration of the liquid medicine and will not destroy the concentration of the liquid medicine.

[0046] The present invention also provides a method for using a Chinese medicine extract storage tank with a filtering device, comprising the following steps: Step S10: The liquid storage tank outlet 12 is connected to the feed port of the centrifuge; the liquid outlet of the centrifuge is connected to the feed port of the turnover tank 16; Step S20: Before use, check whether all facilities and instruments are in good condition, whether the cleaning status meets the requirements, and whether the suction port of the supernatant storage pipe is at the highest point; Step S30: Open the feed inlet valve 17 to feed, and close the feed valve after the feeding is completed; start the pump to extract the supernatant to the concentrator 11 for concentration; Step S40: During the extraction of the supernatant, the liquid level meter 2 is observed to change, and the position is adjusted while observing the distance between the suction port and the sedimentation liquid surface through the manhole 7. When the suction port is close to the sedimentation liquid surface, the suction is stopped, and the valve 17 after the pump, the pump, and the valve 17 before the pump are closed successively; Step S50: Start the centrifuge, open the valve 17 from the liquid storage tank outlet 12 to the centrifuge feed port 21, and start filtering. After the filtering is completed, close the centrifuge and close the corresponding valve 17 to complete the secondary filtering.

[0047] The beneficial effects of this method are: 1. Prolonging the service life of the equipment. Reducing the impact of precipitated impurities on subsequent processes, reducing or avoiding the blockage or adhesion of pipelines, valves 17, and connectors, resulting in unsmooth liquid discharge, improving work efficiency, reducing equipment load, and extending the service life of the equipment; 2. Improve product yield. Reduce waste and process material sticking to the wall, turn waste into treasure, and improve product yield. Calculated based on 7.5 tons of liquid medicine in an 8-ton storage tank, there is about 400L of sediment at the bottom, and the filter residue is about 5-30kg, depending on the product situation. Calculated based on 370L of filtrate, it accounts for about 5% of the total liquid medicine. If it is treated as waste liquid, it is equivalent to wasting 5% (excluding the loss caused by material sticking to the wall and blockage).

[0048] 3. Improve product quality. Improve the impact of precipitated impurities on product taste, appearance and other quality aspects.

[0049] 4. Environmental protection: energy saving and emission reduction. Reducing the amount of waste liquid, reducing the amount of waste liquid treatment, and saving the corresponding environmental protection treatment costs.

It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
