Description

Technical Field

[0001] This invention relates to the field of resin recovery technology, specifically to a resin recovery system and method for mixed liquids in pharmaceutical production. Background Technology

[0002] In pharmaceutical production, various mixtures of components are often obtained, but the actual production needs are only one of the components in the mixture.

[0003] Methanol is commonly used in the pharmaceutical industry as a solvent, extractant, or reaction medium for the extraction, dissolution, or reaction of specific compounds. In pharmaceutical processes, perlite, with its numerous micropores and porous structure, provides a large surface area and adsorption capacity, and is often used to immobilize enzymes, microbial strains, or other bioactive substances. Mycelium may be produced due to the growth of microorganisms during biofermentation. In some pharmaceutical processes, microbial strains (such as bacteria, fungi, or yeast) are cultured in appropriate media, and mycelium is the cell structure formed during their growth. Resins may be used in specific separation, purification, or adsorption processes. Resin particles are commonly used in the pharmaceutical industry as adsorbents, ion exchangers, or column packing materials for the separation and purification of target compounds or the removal of impurities.

[0004] Therefore, pharmaceutical production often yields a mixture of methanol, mycelium, perlite, and resin, but the actual target compound is only adsorbed in the resin. Currently, there is no integrated device on the market that can extract this mixture of methanol, mycelium, perlite, and resin. Summary of the Invention

[0005] To address the technical problem of resin recovery from a mixture of methanol, perlite, mycelium, and resin, this invention provides a resin recovery system and method for pharmaceutical production, thereby resolving the aforementioned issues.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0011] As a preferred embodiment of the present invention, a hot air guide plate is provided inside the first drying box. The hot air guide plate is positioned above and parallel to the second conveyor belt. The hot air guide plate is located close to the hot air inlet. A heating light wave tube is also provided between the hot air guide plate and the second conveyor belt.

[0012] As a preferred embodiment of the present invention, a flow guide plate is provided below the first filter plate, the flow guide plate is used to guide the liquid mixture filtered by the first filter plate, and a liquid outlet is provided at the bottom of the flow guide plate.

[0013] As a preferred embodiment of the present invention, a notch is provided on the side wall of the water tank near the first drying device, the height of the notch being lower than the height of the arc-shaped plate. The resin separation device further includes a second filter plate, a water tank, and a water pump. The second filter plate is inclinedly disposed outside the water tank, with the highest point of inclination of the second filter plate at the notch. The water tank has an open opening and is disposed below the second filter plate. The water pump is used to pump water from the water tank into the water tank.

[0014] As a preferred embodiment of the present invention, the scraper is uniformly provided with a plurality of first filter holes for the passage of fluid, wherein the diameter of the first filter holes is smaller than that of the resin.

[0015] As a preferred embodiment of the present invention, the resin separation device further includes several stirring mechanisms, each stirring mechanism including a second bearing and a third motor. The third motor is used to drive the second bearing to rotate. The second bearing is disposed at the bottom of the water tank and is parallel to the first bearing. Several stirring rods are arranged around the second bearing, and several second filter holes for fluid to pass through are evenly opened on the stirring rods.

[0016] As a preferred embodiment of the present invention, it further includes a second drying device and a finished product placement box. The second drying device includes a second drying box, a third conveyor belt, and a second hot air generator. The third conveyor belt is disposed in the second drying box, and the second hot air generator is used to blow hot air into the second drying box. One end of the third conveyor belt is disposed below the arc-shaped plate, and the other end of the third conveyor belt is disposed above the finished product placement box.

[0017] A method for recovering resin from a mixture in pharmaceutical manufacturing, implemented using the aforementioned pharmaceutical manufacturing mixture resin recovery system, includes the following steps:

[0018] Step A1: The mixture of methanol, perlite, mycelium and resin enters the solid-liquid separation device. The mixture flows through the first filter plate. Methanol and other fluid substances are separated by the first filter plate and fall onto the guide plate, which guides them to be discharged from the liquid outlet.

[0019] Step A2: The first filter plate is left with three solid materials: perlite, mycelium and resin; the first motor drives the first conveyor belt to transport the solid materials on the first filter plate onto the second conveyor belt.

[0020] Step B1: The solid material obtained in step A2 still has methanol adhering to it. The second conveyor belt operates to transport the solid material obtained in step A. The first hot air generator operates to blow hot air into the first drying box. The hot air guide plate evenly blocks the hot air on the surface of the second conveyor belt. The heating light tube operates to irradiate the surface of the second conveyor belt with heat. After drying by the hot air and baking by the heating light tube, the methanol adhering to the solid material on the second conveyor belt is dried.

[0021] Step B2: The methanol vapor obtained during drying is guided by the conical cover and finally enters the condenser through the hot air outlet for condensation, and the methanol is recovered through the condenser.

[0022] Step C1: The dried solid material obtained in step B1 is conveyed by the second conveyor belt and falls into the water tank; the water tank contains water, the resin with a density greater than water falls to the bottom of the water tank, and the perlite and mycelium with a density less than water adhere to the surface of the water in the water tank.

[0023] Step C2: The water pump works, pumping water from the tank into the water trough. After the water is pumped into the trough, the water carries the perlite and mycelium floating in the trough and flows out through the opening onto the second filter plate. The water leaks from the second filter plate into the tank, leaving the perlite and mycelium on the second filter plate.

[0024] Step C3: The third motor drives the second bearing to rotate the stirring rod, pushing the resin that has sunk to the bottom of the tank to the side of the scraper; the second motor drives the first bearing to rotate the scraper, the scraper pushes the resin and pushes it off the curved plate, and the resin falls from the curved plate onto the third conveyor belt.

[0025] Step D: The third conveyor belt operates, conveying the resin obtained in step C3. The second hot air generator operates, blowing hot air into the second drying chamber to dry the resin on the third conveyor belt. The third conveyor belt then conveys the dried resin into the finished product placement box.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In this invention, the methanol can be recovered by setting up a solid-liquid separation device and a first drying device, thus preventing methanol from polluting the air; the resin can be separated from the perlite and mycelium by using a water tank with a partition, and the resin can be separated from the water tank by setting up a rotating scraper, thus achieving the purpose of recovering the resin in the mixed solution.

[0028] 2. In this invention, the first conveyor belt with bristles can brush off the solid mixture adhering to the first filter plate, preventing the perlite, resin and mycelium from sticking to the first filter plate due to their lightness and failing to fall onto the second conveyor belt. In addition, the methanol vapor dried in the first drying device can be recovered by the condenser.

[0029] 3. In this invention, the hot air guide plate can improve the drying efficiency of the hot air emitted by the first hot air generator, the heating light wave tube can provide auxiliary heating to improve the drying effect on the solid mixture with methanol on the second conveyor belt, and the guide plate with liquid outlet can centrally recover the methanol passing through the first filter plate for convenient subsequent processing.

[0030] 4. In this invention, the perlite and mycelium floating on the water tank can be separated by the notch, the second filter plate, the water tank and the water pump, and the water can be recycled at the same time. In addition, the first filter hole can reduce the running resistance of the scraper and the first bearing, and prevent too much water from being scraped out when the scraper scrapes out the resin.

[0031] 5. In this invention, the stirring mechanism can prevent resin particles from accumulating at the bottom of the water tank and push the resin particles toward the rotating scraper, thereby improving the resin separation efficiency. Furthermore, the second drying device can dry the resin separated by the resin separation device, and the final dried resin product is placed in the finished product storage box.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0045] Example 1: Please refer to Figure 1-10The illustrated pharmaceutical manufacturing mixture resin recovery system is used to separate resin from a mixture of methanol, perlite, mycelium, and resin. It includes a solid-liquid separation device 100, a first drying device 200, and a resin separation device 400. The solid-liquid separation device 100 includes an inclined first filter plate 110 through which liquid can pass, preventing perlite, mycelium, and resin from passing through. The first drying device 200 includes a first drying chamber 210, a second conveyor belt 220, and a first hot air generator 230. The second conveyor belt 220 is disposed within the first drying chamber 210, and the first hot air generator 230 is used to blow hot air into the first drying chamber 210. The resin separation device 400 is provided with a water tank 410 and a partition 420. The partition 420 is disposed in the water tank 410 and divides the water tank 410 into two sides connected at the bottom. The second conveyor belt 220 is used to convey the solid mixture to one side of the water tank 410. The other side of the water tank 410 has an arc plate 411 with its axis parallel to the horizontal plane. A rotating scraper 460 is disposed on the arc plate 411. The rotating scraper 460 includes a first bearing 461, a scraper 462 and a second motor 464. The scraper 462 is disposed on the first bearing 461. The second motor 464 is used to drive the first bearing 461 to rotate. The first bearing 461 is collinear with the axis of the arc plate 411.

[0046] Specifically, the solid-liquid separation device 100 is used to separate methanol, the first drying device 200 is used to dry the methanol remaining on the solid mixture, and the resin separation device 400 uses water to separate the resin from the perlite and mycelium based on the principle that the density of perlite and mycelium is less than that of water and the density of resin is greater than that of water.

[0047] More specifically, the liquid can pass through the first filter plate 110, while perlite, resin particles, and mycelium will be blocked by the first filter plate 110. The function of the rotating scraper 460 is to scrape out the resin that has settled at the bottom of the water tank 410 using scraper 462. Due to the presence of the arc-shaped plate 411, when the second motor 464 drives the first bearing 461 and scraper 462 to rotate, the edge of scraper 462 is in contact with the arc-shaped plate 411. Therefore, scraper 462 can scrape the resin from the bottom of the water tank 410 to obtain the separated resin.

[0048] The water tank 410 is divided into two parts by the partition 420. The part near the second conveyor belt 220 is where the solid mixture falls in, with perlite and mycelium floating on the surface. The other part is equipped with an arc plate 411 and a rotating scraper 460 to scrape out the resin. The two parts do not interfere with each other, which can prevent perlite and mycelium from being scraped by the scraper 462, thus preventing the separated resin from containing perlite and mycelium.

[0049] In this embodiment, reference is made to Figure 1-3 As shown,

[0050] The solid-liquid separation device 100 also includes a first conveyor belt 130, which is arranged parallel to the solid-liquid separation device 100 above the first filter plate 110. The first conveyor belt 130 has a first motor 132 for driving the first conveyor belt 130 to convey, and bristles 131 are planted on the first conveyor belt 130.

[0051] Specifically, because mycelium, perlite, and resin particles are light and contain liquid, they are difficult to roll directly off the first filter plate 110. The first motor 132 drives the first conveyor belt 130 to rotate. The first conveyor belt 130, which is closer to the first filter plate 110, moves from top to bottom, causing the bristles 131 to brush the solid matter off the guide plate 120 from top to bottom, and finally fall onto the second conveyor belt 220.

[0052] In this embodiment, reference is made to Figure 4-6 As shown,

[0053] The first drying chamber 210 is provided with a hot air inlet 211 for receiving hot air generated by the first hot air generator 230. The top of the first drying chamber 210 is covered with a conical cover 212. The top of the conical cover 212 has a hot air outlet 213 for discharging hot air. The hot air outlet 213 is connected to a condenser 300.

[0054] Specifically, the hot air generated by the first hot air generator 230 enters through the hot air inlet 211 and blows onto the solid mixture on the second conveyor belt 220, evaporating and carrying away any residual methanol on the solid mixture. The conical cover 212 collects the hot air and discharges it through the hot air outlet 213. The hot air, mixed with the evaporated methanol, enters the condenser 300 from the hot air outlet 213. The condenser 300 condenses the methanol vapor back into methanol, thus recovering the methanol. This also prevents methanol from drifting and polluting the air, and improves the purity of the resin recovered in subsequent processes.

[0055] A hot air guide plate 214 is provided inside the first drying chamber 210. The hot air guide plate 214 is positioned above and parallel to the second conveyor belt 220. The hot air guide plate 214 is positioned close to the hot air inlet 211. A heating light wave tube 240 is also provided between the hot air guide plate 214 and the second conveyor belt 220.

[0056] Specifically, there are multiple heating light wave tubes 240, which are evenly arranged. Through the action of the hot air guide plate 214, the hot air entering from the hot air outlet 213 can be evenly guided to the surface of the second conveyor belt 220, so as to uniformly heat the solid mixture. At the same time, the hot air can also uniformly remove methanol from the solid mixture, thereby improving the methanol removal effect.

[0057] The heating light wave tube 240 can serve as an auxiliary heating element to heat solid mixtures and improve the evaporation efficiency of methanol.

[0058] In this embodiment, reference is made to Figure 1-3 As shown,

[0059] A flow guide plate 120 is provided below the first filter plate 110. The flow guide plate 120 is used to guide the liquid mixture filtered by the first filter plate 110. A liquid outlet 121 is provided at the bottom of the flow guide plate 120.

[0060] Specifically, the methanol flowing down from the first filter plate 110 is guided by the guide plate 120 and finally discharged from the liquid outlet 121 for centralized recovery.

[0061] In this embodiment, reference is made to Figure 7-9 As shown,

[0062] A notch 412 is provided on the side wall of the water tank 410 near the first drying device 200. The height of the notch 412 is lower than the height of the arc plate 411. The resin separation device 400 also includes a second filter plate 430, a water tank 440 and a water pump 450. The second filter plate 430 is inclined and arranged outside the water tank 410. The highest point of the inclination of the second filter plate 430 is at the notch 412. The water tank 440 has an opening and is arranged below the second filter plate 430. The water pump 450 is used to pump water from the water tank 440 into the water tank 410.

[0063] Specifically, the solid mixture dried by the first drying device 200 is conveyed to one side of the water tank 410 via the second conveyor belt 220. Water is present in the water tank 410. Because perlite and mycelium are lighter than water, they float in the water tank 410, while the resin sinks to the bottom. The water pump 450 pumps water from the water tank 440 into the water tank 410, increasing the water level until it overflows from the opening 412. The overflowing water carries the floating perlite and mycelium out of the opening 412 and onto the second filter plate 430. After being filtered by the second filter plate 430, the water passes through the second filter plate 430 and falls back into the water tank 440 for recycling. What remains on the second filter plate 430 are the mycelium and perlite, which are then further processed or recycled.

[0064] In this embodiment, reference is made to Figure 7-9 As shown,

[0065] The scraper 462 is evenly provided with a plurality of first filter holes 463 for the passage of fluid, and the diameter of the first filter holes 463 is smaller than that of the resin.

[0066] Specifically, by setting the first water filter hole 463, the resistance of the rotating scraper 460 during operation can be reduced, and the water can be prevented from being scraped out of the water tank 410 when the scraper 462 and the first bearing 461 rotate, thus affecting the operation of the device.

[0067] In this embodiment, reference is made to Figure 7-9 As shown,

[0068] The resin separation device 400 also includes several stirring mechanisms 470. Each stirring mechanism 470 includes a second bearing 471 and a third motor 474. The third motor 474 is used to drive the second bearing 471 to rotate. The second bearing 471 is located at the bottom of the water tank 410 and is arranged parallel to the first bearing 461. Several stirring rods 472 are arranged around the second bearing 471. Several second filter holes 473 for fluid to pass through are evenly opened on the stirring rods 472.

[0069] Specifically, resin particles that sink to the bottom of the water tank 410 cannot actively approach the rotating scraper 460, resulting in excessive accumulation of resin particles at the bottom of the water tank 410, which cannot be scraped off by the rotating scraper 460 in time. By driving the second bearing 471 to rotate the stirring rod 472 through the third motor 474, excessive accumulation of resin particles can be prevented. At the same time, adjusting the rotation direction of the second bearing 471 and the stirring rod 472 towards the rotating scraper 460 can push the resin particles to the vicinity of the rotating scraper 460, improving the efficiency of the scraper 462 in scraping out resin.

[0070] The second filter hole 473 can reduce the operating resistance of the second bearing 471 and the stirring rod 472 when they rotate in water.

[0071] In this embodiment, reference is made to Figure 10-11 As shown,

[0072] It also includes a second drying device 500 and a finished product placement box 600. The second drying device 500 includes a second drying box 510, a third conveyor belt 520 and a second hot air generator 530. The third conveyor belt 520 is disposed in the second drying box 510. The second hot air generator 530 is used to blow hot air into the second drying box 510. One end of the third conveyor belt 520 is disposed below the arc plate 411 and the other end of the third conveyor belt 520 is disposed above the finished product placement box 600.

[0073] Specifically, the resin particles scraped off by scraper 462 fall onto the third conveyor belt 520. Hot air is blown into the second drying chamber 510 by the second hot air generator 530 to dry the water stains on the resin on the third conveyor belt 520. The dried resin particles are then conveyed by the third conveyor belt 520 to the finished product placement box 600 to obtain recycled resin particles. Example

[0074] A method for recovering resin from a mixture in pharmaceutical manufacturing, implemented using the aforementioned pharmaceutical manufacturing mixture resin recovery system, includes the following steps:

[0075] Step A1: The mixture of methanol, perlite, mycelium and resin enters the solid-liquid separation device 100. The mixture flows through the first filter plate 110. Methanol and other fluid substances are separated by the first filter plate 110 and fall onto the guide plate 120. The guide plate 120 guides the mixture to be discharged from the liquid outlet 121.

[0076] Step A2: The first filter plate 110 is left with three solid substances: perlite, mycelium and resin; the first motor 132 drives the first conveyor belt 130 to transport the solid substances, and the first conveyor belt 130 drives the brush 131 to sweep the solid substances on the first filter plate 110 onto the second conveyor belt 220.

[0077] Step B1: The solid material obtained in step A2 still has methanol adhering to it. The second conveyor belt 220 operates to convey the solid material obtained in step A. The first hot air generator 230 operates to blow hot air into the first drying box 210. The hot air guide plate 214 evenly blocks the hot air on the surface of the second conveyor belt 220. The heating light wave tube 240 operates to irradiate the surface of the second conveyor belt 220 with heat. After drying by hot air and baking by heating light wave tube 240, the methanol adhering to the solid material on the second conveyor belt 220 is dried.

[0078] Step B2: The methanol vapor obtained during drying is guided by the conical cover 212 and finally enters the condenser 300 through the hot air outlet 213 for condensation, and the methanol is recovered through the condenser 300.

[0079] Step C1: The dried solid material obtained in step B1 is conveyed by the second conveyor belt 220 and falls into the water tank 410; there is water in the water tank 410, the resin with a density greater than water falls to the bottom of the water tank 410, and the perlite and mycelium with a density less than water adhere to the surface of the water in the water tank 410.

[0080] Step C2: The water pump 450 operates, pumping water from the water tank 440 into the water trough 410. After the water is pumped into the water trough 410, the water will carry the perlite and mycelium floating in the water trough 410 out through the opening 412 onto the second filter plate 430. The water leaks from the second filter plate 430 back into the water tank 440, leaving the perlite and mycelium on the second filter plate 430.

[0081] Step C3: The third motor 474 drives the second bearing 471 to rotate the stirring rod 472, pushing the resin that has settled at the bottom of the water tank 410 to the side of the scraper 462; the second motor 464 drives the first bearing 461 to rotate the scraper 462, the scraper 462 pushes the resin, pushing the resin out of the arc plate 411, and the resin falls from the arc plate 411 onto the third conveyor belt 520;

[0082] Step D: The third conveyor belt 520 operates, conveying the resin obtained in step C3. The second hot air generator 530 operates, blowing hot air into the second drying box 510 to dry the resin on the third conveyor belt 520. The third conveyor belt 520 then conveys the dried resin into the finished product placement box 600.

[0083] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The rotating scraper (460) includes a first bearing (461), a scraper (462), and a second motor (464). The scraper (462) is disposed on the first bearing (461). The second motor (464) is used to drive the first bearing (461) to rotate. The first bearing (461) is collinear with the axis of the arc plate (411). The solid-liquid separation device (100) further includes a first conveyor belt (130), which is arranged parallel to the solid-liquid separation device (100) above the first filter plate (110). The first conveyor belt (130) has a first motor (132) for driving the first conveyor belt (130) to convey, and the first conveyor belt (130) is equipped with bristles (131). The first drying box (210) is provided with a hot air inlet (211) for receiving hot air generated by the first hot air generator (230), the top of the first drying box (210) is covered with a conical cover (212), the top of the conical cover (212) has a hot air outlet (213) for discharging hot air, and the hot air outlet (213) is connected to a condenser (300). The first drying box (210) is provided with a hot air guide plate (214), which is located above and parallel to the second conveyor belt (220). The hot air guide plate (214) is located near the hot air inlet (211). A heating light wave tube (240) is also provided between the hot air guide plate (214) and the second conveyor belt (220). A flow guide plate (120) is provided below the first filter plate (110). The flow guide plate (120) is used to guide the liquid mixture filtered by the first filter plate (110). A liquid outlet (121) is provided at the bottom of the flow guide plate (120). The water tank (410) has a notch (412) on the side wall near the first drying device (200). The height of the notch (412) is lower than the height of the arc plate (411). The resin separation device (400) also includes a second filter plate (430), a water tank (440), and a water pump (450). The second filter plate (430) is inclined and arranged outside the water tank (410). The highest point of the inclination of the second filter plate (430) is at the notch (412). The water tank (440) has an open opening and is arranged below the second filter plate (430). The water pump (450) is used to pump water from the water tank (440) into the water tank (410). The scraper (462) is uniformly provided with a plurality of first filter holes (463) for passing fluid, the first filter holes (463) being smaller than the diameter of the resin; The resin separation device (400) further includes several stirring mechanisms (470). Each stirring mechanism (470) includes a second bearing (471) and a third motor (474). The third motor (474) is used to drive the second bearing (471) to rotate. The second bearing (471) is located at the bottom of the water tank (410) and is parallel to the first bearing (461). Several stirring rods (472) are arranged around the second bearing (471). Several second filter holes (473) for fluid to pass through are evenly opened on the stirring rods (472). The first motor drives the first conveyor belt to rotate. The first conveyor belt, which is close to the first filter plate, moves from top to bottom, causing the brush bristles to brush the solid matter on the guide plate from top to bottom, and finally fall onto the second conveyor belt. The hot air generated by the first hot air generator enters through the hot air inlet and blows onto the solid mixture on the second conveyor belt, evaporating and carrying away the residual methanol on the solid mixture. The solid mixture, after being dried by the first drying device, is conveyed to one side of the water tank via the second conveyor belt. Water is present in the water tank; since perlite and mycelium are lighter than water, they float in the tank, while the resin sinks to the bottom. A water pump pumps water from the water tank into the water tank, increasing the water level until it overflows from an opening. The overflowing water carries the floating perlite and mycelium out of the opening and onto the second filter plate. After being filtered by the second filter plate, the water passes through and falls back into the water tank for recycling. What remains on the second filter plate are the mycelium and perlite, which are then further processed or recycled.

After the drying by the hot air and the baking by the heating light wave tube (240), the methanol adhering to the solid material on the second conveyor belt (220) is dried. Step B2: The methanol vapor obtained during drying is guided by the conical cover (212) and finally enters the condenser (300) through the hot air outlet (213) for condensation, and the methanol is recovered through the condenser (300). Step C1: The dried solid material obtained in step B1 is conveyed by the second conveyor belt (220) and falls into the water tank (410); there is water in the water tank (410), the resin with a density greater than water falls to the bottom of the water tank (410), and the perlite and mycelium with a density less than water are attached to the surface of the water in the water tank (410). Step C2: The water pump (450) operates, pumping water from the water tank (440) into the water trough (410). After water is pumped into the water trough (410), the water carries the perlite and mycelium floating in the water trough (410) out through the opening (412) onto the second filter plate (430). The water leaks from the second filter plate (430) into the water tank (440), leaving the perlite and mycelium on the second filter plate (430). Step C3: The third motor (474) drives the second bearing (471) to rotate the stirring rod (472), pushing the resin at the bottom of the water tank (410) to the side of the scraper (462); the second motor (464) drives the first bearing (461) to rotate the scraper (462), the scraper (462) pushes the resin, pushing the resin off the arc plate (411), and the resin falls from the arc plate (411) onto the third conveyor belt (520); Step D: The third conveyor belt (520) operates to convey the resin obtained in step C3. The second hot air generator (530) operates to blow hot air into the second drying box (510) to dry the resin on the third conveyor belt (520). The third conveyor belt (520) conveys the dried resin into the finished product placement box (600).
