Description

Technical Field

[0001] This invention relates to the field of concentration technology, and in particular to an integrated defoaming and descorching device for pharmaceutical extraction and concentration. Background Technology

[0002] The integrated steam heating and refrigeration unit, with its core component being a hot reflux extraction and concentration unit, is a widely used complete set of equipment in fields such as traditional Chinese medicine extraction and food processing. Its core structure consists of an extraction tank and a concentrator connected by a closed-loop pipeline. A steam heating jacket heats the medicinal liquid, achieving low-temperature boiling concentration under vacuum conditions to retain heat-sensitive components. Simultaneously, a refrigeration system condenses and recovers the secondary steam, forming a hot reflux cycle.

[0003] The evaporation chamber, as the core component, is the key part for the evaporation and concentration of the medicine. The medicine is heated and boiled here, and the water vaporizes at low temperature under vacuum conditions to form secondary steam, thus concentrating the medicine. Its structural design and functional stability directly affect the concentration efficiency, product quality and operational reliability of the whole machine.

[0004] However, since the liquid medicine often contains natural surfactants such as saponins, proteins, and polysaccharides, it is very easy to generate a large amount of stable foam under boiling and vacuum conditions. The foam carries fine droplets of liquid medicine into the vacuum system, which will cause material loss. In addition, during the concentration process, the liquid medicine is prone to form coking in the cylinder wall area corresponding to the heating jacket, which will affect the quality stability of subsequent batches of products. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an integrated defoaming and descorching device for pharmaceutical extraction and concentration machines. The liquid sprayed out in a divergent manner by the spray ball can perform preliminary defoaming on the foam layer, forming the first stage of defoaming. Furthermore, the spraying power is effectively utilized so that the rotating impeller throws the foam towards the inner wall of the cylinder, completing the second stage of defoaming through the needle-like structure or impact with the cylinder wall.

[0006] The technical solution adopted to solve the above-mentioned technical problems is: an integrated defoaming and descorching device for pharmaceutical extraction and concentration machines, including an evaporation chamber, a spray pipe, a water wheel, a spray ball, an impeller, an impact cylinder, an annular float pipe, needle-like structures, and a cleaning mechanism. The spray pipe is introduced from the outside and connected to the inside of the evaporation chamber. The water wheel is located in the upper gas phase zone of the evaporation chamber. The water inlet end of the water wheel is connected to the water outlet end of the spray pipe. The spray ball is connected to the water outlet end of the water wheel. The impeller is linked with the output shaft of the water wheel and rotates synchronously. The impact cylinder is coaxially sleeved on the outside of the impeller. The impact cylinder rotates relative to the impeller. The annular float pipe is connected to the lower side of the impact cylinder. Multiple sets of needle-like structures are evenly arranged on the inner wall of the impact cylinder. The needle-like structures are used to break up foam. The cleaning mechanism is connected to the lower part of the evaporation chamber. The cleaning mechanism is linked with the impeller.

[0007] Furthermore, the cleaning mechanism includes a support ring, a rotating ring, scraper strips, scraper teeth, an elastic sheet, brush teeth, abutting balls, and arc-shaped protrusions. The support ring is coaxially connected to the lower part of the evaporation chamber, and the rotating ring is coaxially rotatably connected to the upper side of the support ring. Scraper strips are connected to both sides of the rotating ring, and multiple scraper teeth are evenly arranged on both sides of the scraper strips. The upper end of the elastic sheet is fixedly connected to the scraper strips, and the elastic sheet has a wavy structure. Multiple sets of brush teeth are evenly connected to the elastic sheet, and the abutting balls are fixedly connected to the lower end of the elastic sheet. Multiple arc-shaped protrusions are evenly fixedly connected to the support ring along the circumferential direction, and the arc-shaped protrusions are used to push the abutting balls.

[0008] Furthermore, it also includes a rotating component and a torsion spring. Rotating components are rotatably connected to both sides of the rotating ring, and a torsion spring is provided between the rotating component and the rotating ring. The upper end of the rotating component is fixedly connected to the corresponding scraper. In the natural state of the torsion spring, the scraper, the elastic sheet, the brush teeth, and the scraper teeth are all inclined and separated from the inner wall of the evaporation chamber.

[0009] Furthermore, it also includes a beveled ring, a pressing rod, and a socket. The beveled ring is coaxially connected to the lower side of the impeller, the pressing rod is connected to the upper end of the scraper, and multiple sockets are evenly opened along the circumferential direction on the lower side of the impeller. The sockets are close to the beveled ring, and the upper end of the pressing rod can be inserted into the socket.

[0010] Furthermore, it also includes: a corresponding arc surface is formed on the side of the arc-shaped protrusion adjacent to the rotating ring, and the rotating ring slides relative to the arc-shaped protrusion through the arc surface.

[0011] Furthermore, it also includes a splined shaft, a sliding sleeve, and a connecting rod. The splined shaft is coaxially and fixedly connected to the output end of the water turbine. The splined shaft is coaxially and rotatably connected to the evaporation chamber. The sliding sleeve is vertically and slidably sleeved on the splined shaft. Connecting rods are fixedly connected to both sides of the sliding sleeve. The lower end of the connecting rod is fixedly connected to the impeller.

[0012] Furthermore, it also includes a one-way bearing, a countershaft, a magnetic coupler, a motor, and an airflow channel. The inner ring of the one-way bearing is fixedly connected to the upper end of the splined shaft, the countershaft is fixedly connected to the outer ring of the one-way bearing, the magnetic coupler is coaxially connected to the upper end of the evaporation chamber, the motor is connected to the upper outside of the evaporation chamber, the motor drives the countershaft through the magnetic coupler, and the airflow channel is eccentrically connected to one side of the evaporation chamber.

[0013] Furthermore, it also includes: the rotating ring, the impeller, the impact cylinder, and the inclined ring can all be separated into two semi-circular structures, and the conical cover is sleeved on the outside of the water wheel.

[0014] The beneficial effects of this invention are as follows: (1) This invention introduces return liquid (condensate) by setting up a spray pipe, and uses the flow kinetic energy of the spray liquid itself to drive the water wheel to rotate. The water wheel then drives the impeller to rotate synchronously, effectively utilizing the spray power. The liquid sprayed out in a divergent manner by the spray ball can perform preliminary defoaming on the foam layer, forming the first stage of defoaming. The impeller always floats on the liquid surface under the action of the annular float pipe, and automatically adjusts its height as the liquid level rises and falls, ensuring that the impeller is always located in the foam enrichment area. The rotating impeller throws the foam towards the inner wall of the impact cylinder, and completes the second stage of defoaming through the needle-like structure or impact with the cylinder wall. This structure makes full use of the existing spray liquid energy of the system and realizes the dynamic self-adaptation of the defoaming mechanism and the liquid surface, significantly improving the defoaming efficiency. (2) The present invention provides a cleaning mechanism at the bottom of the evaporation chamber. The mechanism includes components such as scraper, scraper teeth, elastic sheet and brush teeth. During normal evaporation, the cleaning mechanism is kept in an inclined state by the action of torsion spring. The scraper teeth and brush teeth are separated from the inner wall of the evaporation chamber to avoid interfering with the heat transfer of the heating jacket area. At the same time, it prevents the cleaning mechanism itself from becoming a focal point. When evaporation is completed and the liquid is discharged, the impeller descends with the liquid level. Through the cooperation of the inclined ring and the extrusion rod, the scraper is automatically driven to rotate to the vertical working position, so that the scraper teeth and brush teeth are in contact with the inner wall of the evaporation chamber. The extrusion rod is inserted into the insertion hole to realize the reliable linkage between the impeller and the cleaning mechanism. It realizes the function of automatic docking only when cleaning, which not only ensures the stability of the concentration process, but also solves the problem that the coking material affects the quality stability of subsequent batches of products. (3) In the cleaning mechanism of the present invention, the scraper drives the scraper teeth to achieve circumferential rotation and scraping, which is used to remove the hardened coking layer on the cylinder wall. At the same time, the abutting ball set at the bottom of the wave-shaped elastic sheet repeatedly abuts against the arc-shaped protrusion fixed on the support ring during the rotation of the scraper, generating periodic shaking, which drives the brush teeth to reciprocate and scrub the cylinder wall mainly in the vertical direction. This structure expands the single rotation scraping into a composite cleaning motion that combines rotation and vertical, which significantly improves the ability to remove coking material and makes cleaning more thorough.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] like Figures 1-10 As shown in the figure, this embodiment provides an integrated defoaming and descorching device for a pharmaceutical extraction and concentration machine, including an evaporation chamber 1, a spray pipe 2, a water wheel 3, a spray ball 4, an impeller 5, an impact cylinder 6, an annular float pipe 7, a needle-like structure 8, and a cleaning mechanism 9. The spray pipe 2 is introduced from the outside and connected to the inside of the evaporation chamber 1. The water wheel 3 is located in the upper gas phase zone of the evaporation chamber 1. The water inlet end of the water wheel 3 is connected to the water outlet end of the spray pipe 2. The spray ball 4 is connected to the water outlet end of the water wheel 3. The impeller 5 is linked with the output shaft of the water wheel 3 and rotates synchronously. The impact cylinder 6 is coaxially sleeved on the outside of the impeller 5 and rotates relative to the impeller 5. The annular float pipe 7 is connected to the lower side of the impact cylinder 6. Multiple sets of needle-like structures 8 are evenly arranged on the inner wall of the impact cylinder 6. The needle-like structures 8 are used to break up foam. The cleaning mechanism 9 is connected to the lower part of the evaporation chamber 1 and can be linked with the impeller 5.

[0028] In the above embodiments, by introducing return liquid (condensate) through spray pipe 2, the water wheel 3 is driven to rotate by the flow kinetic energy of the spray liquid itself. The water wheel 3 then drives the impeller 5 to rotate synchronously, effectively utilizing the spray power. The liquid sprayed out in a divergent manner by spray ball 4 can perform preliminary defoaming on the foam layer, forming the first stage of defoaming. The impeller 5 always floats on the liquid surface under the action of the annular float pipe 7, and automatically adjusts its height as the liquid level rises and falls, ensuring that the impeller 5 is always located in the foam enrichment area. The rotating impeller 5 throws the foam towards the inner wall of the impact cylinder 6, and completes the second stage of defoaming through the needle-like structure 8 or by impacting the cylinder wall. This structure makes full use of the existing spray liquid energy of the system and realizes the dynamic self-adaptation of the defoaming mechanism and the liquid surface, significantly improving the defoaming efficiency.

[0029] Specifically, the cleaning mechanism 9 includes a support ring 91, a rotating ring 92, a scraper 93, scraper teeth 94, an elastic sheet 95, brush teeth 96, an abutment ball 97, and an arc-shaped protrusion 98. The support ring 91 is coaxially connected to the lower part of the inner side of the evaporation chamber 1. The rotating ring 92 is coaxially rotatably connected to the upper side of the support ring 91. Scraper 93 is connected to both sides of the rotating ring 92. Multiple scraper teeth 94 are evenly arranged on both sides of the scraper 93. The upper end of the elastic sheet 95 is fixed to the scraper 93. The elastic sheet 95 has a wave-like structure. Multiple sets of brush teeth 96 are evenly connected to the elastic sheet 95. The abutment ball 97 is fixed to the lower end of the elastic sheet 95. Multiple arc-shaped protrusions 98 are evenly fixed to the support ring 91 along the circumferential direction. The arc-shaped protrusions 98 are used to push the abutment ball 97. It also includes a rotating component 10 and a torsion spring 11. The rotating component 10 is rotatably connected to both sides of the rotating ring 92. A torsion spring 11 is provided between the rotating component 10 and the rotating ring 92. The upper end of the rotating component 10 is fixedly connected to the corresponding scraper 93. In the natural state of the torsion spring 11, the scraper 93, elastic sheet 95, brush tooth 96 and scraper tooth 94 are all inclined and separated from the inner wall of the evaporation chamber 1. It also includes a beveled ring 12, a pressing rod 13 and a socket 14. The beveled ring 12 is coaxially connected to the lower side of the impeller 5. The pressing rod 13 is connected to the upper end of the scraper 93. Multiple sockets 14 are evenly opened along the circumferential direction on the lower side of the impeller 5. The sockets 14 are close to the beveled ring 12. The upper end of the pressing rod 13 can be inserted into the socket 14. It also includes: a corresponding arc surface 15 is opened on the side of the arc protrusion 98 adjacent to the rotating ring 92, and the rotating ring 92 slides relative to the arc protrusion 98 through the arc surface 15.

[0030] In the above embodiments, during normal evaporation, the cleaning mechanism 9 is kept in an inclined state by the action of the torsion spring 11, and the scraper teeth 94 and brush teeth 96 are separated from the inner wall of the evaporation chamber 1 to avoid interfering with the heat transfer of the heating jacket area. At the same time, it prevents the cleaning mechanism 9 itself from becoming a focal point. When evaporation is completed and the liquid is discharged, the impeller 5 descends with the liquid level. Through the cooperation of the inclined ring 12 and the extrusion rod 13, the scraper 93 is automatically driven to rotate to the vertical working position, so that the scraper teeth 94 and brush teeth 96 are in contact with the inner wall of the evaporation chamber 1. The extrusion rod 13 is inserted into the insertion hole 14 to realize the reliable linkage between the impeller 5 and the cleaning mechanism 9. It realizes the function of automatic docking only when cleaning, which not only ensures the stability of the concentration process, but also solves the problem that the coking material affects the quality stability of subsequent batches of products. The arc-shaped protrusion 98 not only pushes the contact ball 97, but also enables the rotating ring 92 to rotate stably through the arc surface 15.

[0031] Specifically, it also includes a spline shaft 16, a sliding sleeve 17 and a connecting rod 18. The spline shaft 16 is coaxially fixed to the output end of the water turbine 3. The spline shaft 16 is coaxially rotatably connected to the evaporation chamber 1. The sliding sleeve 17 is vertically slidably sleeved on the spline shaft 16. Connecting rods 18 are fixed to both sides of the sliding sleeve 17. The lower end of the connecting rod 18 is fixed to the impeller 5.

[0032] In the above embodiments, by setting the spline shaft 16, the sliding sleeve 17 and the connecting rod 18, the impeller 5 and the output shaft of the water turbine 3 are linked, so that the impeller 5 can not only rotate synchronously with the output shaft of the water turbine 3, but also move up and down with the annular float tube 7.

[0033] Specifically, it also includes a one-way bearing 19, a countershaft 20, a magnetic coupler 21, a motor 22, and an airflow channel 23. The inner ring of the one-way bearing 19 is fixedly connected to the upper end of the spline shaft 16, the countershaft 20 is fixedly connected to the outer ring of the one-way bearing 19, the magnetic coupler 21 is coaxially connected to the upper end of the evaporation chamber 1, the motor 22 is connected to the upper part of the outside of the evaporation chamber 1, and the motor 22 drives the countershaft 20 through the magnetic coupler 21. The airflow channel 23 is eccentrically connected to one side of the evaporation chamber 1.

[0034] In the above embodiments, by further configuring the motor 22, magnetic coupler 21, and one-way bearing 19 as backup drive schemes, when cleaning is carried out after the liquid is discharged, if the driving force of the spray liquid is insufficient or the coking material is strongly adhered, the motor 22 can be activated to drive the internal mechanism to rotate at high speed through magnetic coupling to achieve high-intensity cleaning. The setting of one-way bearing 19 ensures that the spray drive and the motor 22 drive do not interfere with each other, and the two modes can be flexibly switched, improving the equipment's adaptability to different working conditions and cleaning reliability.

[0035] Specifically, it also includes: the rotating ring 92, impeller 5, impact cylinder 6 and inclined ring 12 can all be separated into two semi-circular structures, the conical cover 24 is sleeved on the outside of the water wheel 3, and the input end of the water wheel 3 is led out through the conical cover 24.

[0036] In the above embodiments, key components such as the rotating ring 92, impeller 5, impact cylinder 6, and inclined ring 12 are all designed to be detachable into two semi-circular structures, which can be installed or removed as a whole through the manhole of the evaporation chamber 1, greatly reducing the difficulty of installing and cleaning the internal mechanism offline. The cone cover 24 is streamlined and covers the water wheel 3, which is convenient for cleaning and rinsing.

[0037] The working principle of this invention is as follows: During normal concentration operation in the evaporation chamber 1, the liquid boils and produces a large amount of foam. At this time, the external high-pressure liquid pump sends the return liquid (condensate) into the spray pipe 2. The return liquid first washes the water wheel 3, driving the water wheel 3 to rotate. The water wheel 3 drives the impeller 5 to rotate synchronously through the spline shaft 16, the sliding sleeve 17 and the connecting rod 18. The spray liquid is then sprayed downward through the spray ball 4 to perform preliminary defoaming on the foam layer. Impeller 5 floats on the liquid surface under the buoyancy of the annular float tube 7, and automatically adjusts its height according to the rise and fall of the liquid level to ensure that impeller 5 is always in the foam enrichment area. The rotating impeller 5 throws the foam towards the inner wall of the impact cylinder 6 on the outside. The needle-like structure 8 on the inner wall of the impact cylinder 6 causes the foam to break quickly. The gas in the foam is extracted by the vacuum system (existing technology), and the liquid flows back to the main body of the liquid, achieving efficient defoaming. During this stage, the one-way bearing 19 causes the spline shaft 16 and the secondary shaft 20 to rotate relative to each other. The motor 22 drive system does not participate in the work. At the same time, the cleaning mechanism 9 is kept in an inclined state under the action of the torsion spring 11. The scraper teeth 94 and brush teeth 96 are separated from the inner wall of the evaporation chamber 1 to avoid interference with the heating and evaporation process. After the evaporation operation is completed and the liquid is discharged, the liquid level drops. The impeller 5, annular float tube 7, impact cylinder 6, and inclined ring 12 move down synchronously with the liquid level. The inclined ring 12 contacts the squeezing rod 13 at the upper end of the scraper 93. Under the guidance of the inclined surface, the squeezing rod 13 is pushed to rotate, causing the scraper 93 to rotate to a vertical position against the spring force of the torsion spring 11. This makes the scraper teeth 94 and brush teeth 96 fit tightly against the inner wall of the evaporation chamber 1. Then, the upper end of the squeezing rod 13 abuts against the lower side of the impeller 5. The spray system sends in cleaning water, driving the impeller 5 to rotate. The rotation of the impeller 5 is opposite to the upper end of the squeezing rod 13. Slide until the upper end of the extrusion rod 13 is inserted into the insertion hole 14. Then, the impeller 5 drives the rotating ring 92 and the scraper 93 to rotate synchronously through the extrusion rod 13. The scraper teeth 94 on the scraper 93 scrape the cylinder wall in a circumferential manner to remove the hardened coking layer. At the same time, the scraper 93 drives the wave-shaped elastic sheet 95 to rotate. The abutting ball 97 at the bottom of the elastic sheet 95 repeatedly abuts against the arc-shaped protrusion 98 on the support ring 91 during the rotation, causing the elastic sheet 95 to shake periodically. This drives the brush teeth 96 to reciprocate and scrub the cylinder wall in the vertical direction, achieving a composite cleaning of the cylinder wall. When the amount of cleaning water is controlled below the annular float tube 7, the cleaning mechanism 9 can rotate continuously for cleaning. Then the amount of cleaning water can be increased so that the spray ball 4 sprays water to thoroughly rinse the evaporation chamber 1 and discharge the wastewater. The cleaning process can be repeated several times to complete the cleaning process. For coking materials with strong adhesion, after completing the above-mentioned water-driven cleaning, the motor 22 drive mode can be activated. The motor 22 drives the secondary shaft 20 to rotate through the magnetic coupler 21. The secondary shaft 20 drives the spline shaft 16 and internal mechanism to rotate at high speed through the one-way bearing 19, achieving high-intensity cleaning. The one-way bearing 19 ensures that the motor 22 drive system does not interfere in the spray drive mode. The two modes can be flexibly switched to meet different cleaning needs.

[0038] It should be noted that the brush teeth 96, scraper teeth 94, and scraper strip 93 on the elastic sheet 95 are made of polytetrafluoroethylene (PTFE). The overall structure is designed to be lightweight while meeting strength requirements, so as to reduce the load on moving parts. The magnetic coupler 21 includes an outer magnetic rotor, an isolation sleeve, and an inner magnetic rotor, which is existing technology. It achieves contactless power transmission by penetrating the isolation sleeve through the magnetic field, avoiding the need to open a dynamic sealing hole at the top of the evaporation chamber 1. This device also includes an external pipeline and valve body connected to the spray pipe 2, which are used to introduce reflux liquid and cleaning water, respectively. The specific selection and connection method can be conventionally set by those skilled in the art according to the actual process. The introduced reflux liquid is distilled water obtained by condensation in the condenser. Its composition is the same as the volatile components in the liquid medicine and does not contain exogenous chemical substances. Therefore, it will not affect the purity of the liquid medicine when sprayed onto the foam layer. After the rotating ring 92, impeller 5, impact cylinder 6 and inclined ring 12 are split into two halves, they are connected by countersunk screws or snap-fit ​​quick-connect structure to ensure convenient disassembly and assembly and reliable connection. During the rotation cleaning phase of the cleaning mechanism 9, the liquid level is maintained at the lower side of the annular float tube 7 by controlling the amount of cleaning water entering. This prevents the impeller 5 and the inclined ring 12 from moving upward due to buoyancy, which would cause the squeezing rod 13 to detach from the insertion hole 14. Specifically, this can be monitored by setting a liquid level sight glass or liquid level sensor on the side wall of the evaporation chamber 1. Those skilled in the art can adjust it according to the actual equipment.
