Description

Technical Field

[0001] This invention relates to the field of gel production equipment technology, specifically to an auxiliary device for removing air bubbles in gels. Background Technology

[0002] Gels, as high-viscosity semi-solid formulations with a three-dimensional network structure, are widely used in pharmaceutical dressings, cosmetic gels, food thickeners, and industrial adhesives. During the formulation, delivery, and filling processes of gels, a large amount of air is easily trapped or mixed into the system, forming bubbles. The presence of these bubbles can lead to problems such as uneven porosity in the product appearance, inaccurate filling dosage, segregation of active ingredients, and decreased oxidative stability. Therefore, effectively removing bubbles from gels is a key process step to ensure product quality.

[0003] Existing methods for removing air bubbles from gels mainly include vacuum static degassing, centrifugal degassing, and agitation degassing. Vacuum static degassing utilizes the pressure difference between the inside and outside of the bubbles to cause them to expand, rise, and burst. However, for gels with high viscosity, this method results in high resistance to bubble rise, an extremely slow degassing process, and difficulty for deep, tiny bubbles to escape completely due to their own buoyancy, leading to low efficiency. Centrifugal degassing uses the centrifugal force generated by high-speed rotation to achieve phase separation and migration based on the density difference between the bubbles and the gel matrix. However, the container must maintain dynamic balance during centrifugation, resulting in complex equipment structures. Furthermore, the frictional heat and mechanical shearing generated by high-speed rotation can easily damage the original three-dimensional network structure of the gel, even causing phase separation or a decrease in viscosity. Agitation degassing introduces agitators to assist in the spreading of the gel, but the rotational shearing of the agitator can damage the gel structure and introduce new air bubbles. Ultrasonic degassing utilizes the cavitation effect generated by ultrasound in a liquid to cause tiny bubbles to coalesce into larger bubbles and accelerate their rise. The existing methods are independent of each other, making it difficult to balance the technical contradiction of high degassing efficiency and gel structure integrity: vacuum settling method is inefficient, centrifugation and stirring methods are highly destructive and not suitable for high viscosity systems. These defects seriously restrict the industrial continuous production of high-quality gelling agents. Summary of the Invention

[0004] This invention aims to provide an auxiliary device for removing air bubbles from gels. The device performs three sequential and synergistic processes: pressurized bubble breaking in a pressurized chamber, ultrasonic vibration debubbling in an ultrasonic chamber, and vacuum debubbling in a vacuum chamber. This effectively removes air bubbles from the gel while preserving its three-dimensional network structure, thus solving the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A gel degassing auxiliary device includes a pressurized input pump, a hopper, and a collector. The hopper is connected to a support base. The hopper has, from top to bottom, an independent pressurized chamber, an ultrasonic chamber, and a vacuum chamber. Partition plates are provided between the pressurized chamber and the ultrasonic chamber, and between the ultrasonic chamber and the vacuum chamber. The upper side of the pressurized chamber is connected to an interface for connection to the pressurized input pump, and a detachable cover is connected to the interface. An ultrasonic generator is installed inside the ultrasonic chamber to perform ultrasonic vibration degassing on the gel inside. A vacuum generator is connected outside the vacuum chamber to perform vacuum degassing on the gel inside. The collector is located below the outlet of the vacuum chamber and is used to collect the degassed gel. The outlet of the vacuum chamber is connected to a control valve to control its connection status.

[0007] Furthermore, the ultrasonic chamber is provided with a reducing plate and an expanding plate. The outer side wall of the reducing plate is smaller at the top and larger at the bottom, while the inner side wall of the expanding plate is larger at the top and smaller at the bottom. The reducing plate is located directly above the expanding plate, and the upper tip of the reducing plate is located directly below the outlet of the pressurized chamber, while the lower side of the expanding plate is located directly above the inlet of the vacuum chamber.

[0008] Furthermore, the tapered outer wall of the reducing plate is provided with several baffles, which cooperate with each other to form a guide groove extending along its generatrix on the outer surface of the reducing plate; the tapered inner wall of the expanding plate is provided with a spiral annular flow channel; after the gel enters the ultrasonic chamber, it impacts the upper tip of the reducing plate and spreads evenly along the guide groove to form a thin film fluid, increasing the surface area of ​​the gel and exposing the air bubbles encapsulated inside the gel; the gel flowing down from the reducing plate enters the annular flow channel of the expanding plate, and the exposed air bubbles gradually expand, rise and burst.

[0009] Furthermore, the upper cone angle of the reduced diameter plate is 30°~60°, and the depth of the guide groove is 2~10mm and the width is 3~8mm.

[0010] Furthermore, the lower end cone angle of the expansion plate is 45°~90°, and the radial width of the annular flow channel is 5~15mm.

[0011] Furthermore, a connecting seat is connected to the lower side of the reduced diameter plate, the connecting seat is slidably disposed inside the ultrasonic chamber, a first motor is connected to the outer side of the hopper, the output shaft of the first motor is connected to a first eccentric cam, the lower end face of the connecting seat slides against the rim of the first eccentric cam, and the upper tip of the reduced diameter plate slides through the partition plate between the pressurized chamber and the ultrasonic chamber.

[0012] Furthermore, the outer wall of the expanding plate is slidably connected to the inner wall of the ultrasonic chamber, a second motor is connected to the outer side of the hopper, the output shaft of the second motor is connected to a second eccentric cam, the upper end face of the expanding plate is slidably abutting against the rim of the second eccentric cam, and a cylindrical sliding part is provided on the lower side of the expanding plate, the sliding part being slidably inserted through the partition plate between the ultrasonic chamber and the vacuum chamber.

[0013] Furthermore, the hopper is also connected to a control center. The first motor and the second motor are both servo motors. The control center is electrically connected to the first motor and the second motor and controls the output speed and direction of their output shafts so that the connecting seat and the expansion plate move in opposite directions along the vertical inner wall of the ultrasonic chamber.

[0014] The principles and beneficial effects of the technical solution are as follows:

[0015] 1. This invention provides an auxiliary device for removing air bubbles from a gelling agent. The hopper is configured from top to bottom with independent pressurized chambers, ultrasonic chambers, and vacuum chambers. The gelling agent enters the pressurized chamber under the action of a pressurized input pump and flows sequentially through the three chambers, undergoing three stages of treatment: pressurized compression to break bubbles, ultrasonic vibration to promote bubble formation, and vacuum degassing. Specifically, after entering the pressurized chamber, the bubbles collapse under pressure. In the ultrasonic chamber, the ultrasonic generator utilizes the cavitation and mechanical vibration effects generated by ultrasound in the gelling agent to cause small bubbles encapsulated by a high-viscosity matrix to coalesce, grow, or loosen, giving the previously difficult-to-escape deep bubbles greater buoyancy and weaker interfacial confinement. After ultrasonic pretreatment, the gelling agent enters the vacuum chamber, where the bubbles rapidly expand, rise, and collapse under vacuum pressure. The three-stage processing steps proceed sequentially and work synergistically. The first two stages (pressure compression and ultrasonic vibration) aggregate small bubbles into large bubbles (bubble compression interface fusion and merging, and ultrasound causing small bubbles to collide and break into large bubbles). The negative pressure chamber removes the large bubbles, overcoming the shortcomings of existing single methods that have limited effectiveness and difficulty in balancing efficiency and gel structure integrity. This forms a complete bubble removal chain, which can effectively remove bubbles from the gel and does not introduce any stirring components throughout the process, thus not damaging the three-dimensional network structure of the gel. The treated gel can effectively maintain its original rheological and physicochemical properties.

[0016] 2. This invention provides an auxiliary device for removing gel bubbles. A reducing plate and an expanding plate are installed within an ultrasonic chamber. The reducing plate has a conical structure, wider at the bottom and narrower at the top, with several baffles on its outer wall forming a guide channel extending along the generatrix. The expanding plate has an inverted conical structure, wider at the top and narrower at the bottom, with a spiral annular flow channel on its inner wall. After the gel falls from the outlet of the pressurized chamber, it first impacts the upper tip of the reducing plate. Guided by the conical surface, it spreads evenly along the guide channel, forming a thin film of fluid. This increases the surface area of ​​the gel, allowing the bubbles encapsulated within to be fully exposed. The gel flowing from the reducing plate then enters the spiral annular flow channel of the expanding plate. The spiral flow channel prolongs the residence time and flow path of the gel within the vacuum chamber, giving the exposed bubbles sufficient time to expand, rise, and burst. The reducing plate achieves "spreading and exposure," while the expanding plate achieves "delayed debubbling." The combined effect of these two components significantly improves the efficiency of the vacuum debubbling process. The upper cone angle of the reducing plate is set to 30°~60°, the depth of the guide groove is 2~10mm, and the width is 3~8mm. The lower cone angle of the expanding plate is set to 45°~90°, and the radial width of the annular flow channel is 5~15mm. This ensures that the gelling agent does not accumulate and stagnate on the cone surface due to the gentle slope, nor does it flow too fast due to the steep slope, resulting in insufficient film formation.

[0017] 3. The present invention provides an auxiliary device for removing air bubbles from a gel agent. A connecting seat is connected to the lower side of a reducing plate, which is slidably disposed inside an ultrasonic chamber. A first motor is connected to the outer side of a material hopper, and the output shaft of the first motor is connected to a first eccentric cam. The lower end face of the connecting seat slidably abuts against the rim of the first eccentric cam. The outer wall of an expanding plate is slidably connected to the inner wall of the ultrasonic chamber. A second motor is connected to the outer side of the material hopper, and the output shaft of the second motor is connected to a second eccentric cam. The upper end face of the expanding plate slidably abuts against the rim of the second eccentric cam. A control center is electrically connected to the first and second motors, which function as servo motors, and controls the rotational speed and direction of their output shafts. During the defoaming process, the control center drives the first and second motors to operate, which, through the eccentric cam mechanism, respectively drive the connecting seat and the expanding plate to reciprocate along the vertical direction of the ultrasonic chamber. The control center ensures that the connecting seat and the expanding plate always move in opposite directions; that is, when the reducing plate moves upward, the expanding plate moves downward, and vice versa. This reverse motion design results in three main effects: First, the axial distance between the reducing and expanding plates changes periodically. When the distance decreases, the gelling agent is subjected to compression and shearing between the two cones, prompting further detachment of bubbles from the gel matrix. When the distance increases, the gelling agent gains more space to spread, which is beneficial for bubble exposure. Second, the reciprocating motion of the reducing plate causes its upper tip to periodically shift relative to the outlet of the pressurized chamber, changing the gelling agent's landing point and making its spread on the reducing plate surface more uniform, avoiding local accumulation and uneven film formation caused by a fixed landing point. Third, the reciprocating motion of the expanding plate subjectes the gelling agent in the spiral annular channel to alternating shearing, enhancing the relative motion between bubbles and the gel matrix, and promoting bubble coalescence and detachment.

[0018] 4. This invention provides an auxiliary device for removing air bubbles from gels. Partition plates are installed between the pressurized chamber and the ultrasonic chamber, and between the ultrasonic chamber and the vacuum chamber. The three chambers are independent of each other, each maintaining its required process environment. The pressurized chamber maintains a positive pressure environment through an external pressurization pump, applying a crushing effect to the bubbles. The ultrasonic chamber operates under normal pressure or slightly positive pressure conditions, ensuring that the cavitation effect generated by the ultrasonic generator fully acts on the interior of the gel. The vacuum chamber maintains a negative pressure environment through an external vacuum generator, providing the driving force for the expansion and buoyancy of the bubbles. The partition plates allow for independent adjustment of the pressurization pressure, ultrasonic power, and vacuum level in each of the three chambers to adapt to the processing needs of gels with different viscosities and bubble contents.

[0019] 5. This invention provides an auxiliary device for removing air bubbles from a gel. A removable cover is provided on the upper side of the pressurized chamber. Opening the cover allows connection to a pressurized input pump to add the gel to be treated into the pressurized chamber. Closing the cover creates a relatively sealed processing space within the pressurized chamber. A control valve is connected to the outlet of the vacuum chamber to control its connection status. This valve is opened after one batch of processing is completed to discharge the defoamed gel to a collector. The entire device utilizes a top-down pressure and gravity-driven flow method, avoiding the possibility of introducing new air bubbles due to mechanical shearing during the conveying process. The collector is located below the outlet of the pressurized chamber, directly collecting the processed, bubble-free gel. The device is compact and easy to operate. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0027] like Figures 1 to 4 As shown, an auxiliary device for removing gel bubbles includes a pressurized input pump (not shown), a hopper 1, and a collector 2. The hopper 1 is fixedly supported by a support base 6, and the collector 2 is located directly below the hopper 1. The hopper 1 has, from top to bottom, a pressurized chamber 3, an ultrasonic chamber 4, and a vacuum chamber 5. A partition plate 7 is provided between the pressurized chamber 3 and the ultrasonic chamber 4, and also between the ultrasonic chamber 4 and the vacuum chamber 5. The two partition plates 7 make the three chambers independent of each other. The bottom of the support base 6 has feet, the lower ends of which are flush with the outer bottom wall of the collector 2, ensuring the overall stability of the device.

[0028] An interface is located on the upper side of the pressurized chamber 3, which is connected to a pressurized input pump via a pipeline. The pressurized input pump is used to pressurize and deliver the gel to be processed into the pressurized chamber 3. A cover can also be detachably connected to the interface. When the cover is open, the pressurized input pump pipeline can be connected; when the cover is closed, the pressurized chamber 3 forms a sealed processing space. A pressure sensor (not shown in the figure) is installed on the inner wall of the pressurized chamber 3 for real-time monitoring of the pressure inside the chamber. A discharge port is located at the bottom of the pressurized chamber 3, which passes through the partition plate 7 and leads to the ultrasonic chamber 4.

[0029] The ultrasonic chamber 4 contains a reducing plate 8 and an expanding plate 9, with the reducing plate 8 located directly above the expanding plate 9. The reducing plate 8 has a conical structure, wider at the bottom and narrower at the top, with its upper tip positioned directly below the outlet of the pressurized chamber 3. Several baffles 10 are provided on the outer conical wall of the reducing plate 8, evenly arranged along the generatrix of the conical surface, forming guide channels between adjacent baffles 10. The expanding plate 9 has an inverted conical structure, wider at the top and narrower at the bottom, with a spiral annular flow channel on its inner conical wall. The lower side of the expanding plate 9 is positioned directly above the inlet of the vacuum chamber 5. Several ultrasonic generating devices (not shown in the figure) are installed on the inner wall of the ultrasonic chamber 4, evenly arranged in the vertical plane of the ultrasonic chamber 4 to ensure uniform distribution of the ultrasonic field throughout the chamber. The inner side of the ultrasonic chamber 4 is also equipped with a heating element (not shown in the figure). The heating element is an electric heating wire or an electric heating tube, which is used to moderately heat the gel in the chamber to reduce its viscosity.

[0030] A connecting seat 11 is fixedly connected to the lower side of the reduced diameter plate 8. The connecting seat 11 is slidably disposed on the inner side wall of the ultrasonic chamber 4 and can slide back and forth along the vertical direction of the ultrasonic chamber 4. A first motor is fixedly connected to the outer side wall of the hopper 1. The output shaft of the first motor passes through the side wall of the hopper 1 and extends into the ultrasonic chamber 4. A first eccentric cam is fixedly connected to the end of the output shaft. The lower end face of the connecting seat 11 slides against the rim of the first eccentric cam. The upper tip of the reduced diameter plate 8 slides through the partition plate 7 between the pressurization chamber 3 and the ultrasonic chamber 4. A first through hole is provided on the partition plate 7 for the upper end of the reduced diameter plate 8 to pass through. When the first motor is running, the first eccentric cam rotates and pushes the connecting seat 11 to reciprocate in the vertical direction. The connecting seat 11 drives the reduced diameter plate 8 to reciprocate together. The upper tip of the reduced diameter plate 8 slides up and down in the first through hole of the partition plate 7, changing the material drop distance between the upper end of the reduced diameter plate 8 and the outlet of the pressurization chamber 3.

[0031] The outer wall of the expansion plate 9 is slidably connected to the inner wall of the ultrasonic chamber 4, and the expansion plate 9 can slide back and forth along the vertical direction of the ultrasonic chamber 4. A second motor 12 is fixedly connected to the outer wall of the hopper 1. The output shaft of the second motor 12 passes through the side wall of the hopper 1 and extends into the ultrasonic chamber 4. A second eccentric cam 13 is fixedly connected to the end of the output shaft. The upper end face of the expansion plate 9 slides against the rim of the second eccentric cam 13. A cylindrical sliding part is provided on the lower side of the expansion plate 9. The sliding part slides through the partition plate 7 between the ultrasonic chamber 4 and the vacuum chamber 5. A second through hole is provided on the partition plate 7 for the sliding part to pass through. An axially penetrating flow channel hole is provided at the center of the sliding part. This flow channel hole is the feed inlet of the vacuum chamber 5. When the second motor 12 is running, the second eccentric cam 13 rotates and pushes the expansion plate 9 to reciprocate in the vertical direction.

[0032] A control center is also connected to the outside of the hopper 1. The first motor and the second motor 12 are both servo motors, and the control center is electrically connected to the first motor and the second motor 12. The control center controls the speed and direction of rotation of the output shafts of the first motor and the second motor 12, so that the connecting seat 11 and the expansion plate 9 always maintain opposite movements along the vertical direction of the ultrasonic chamber 4, that is, when the reduction plate 8 moves upward, the expansion plate 9 moves downward, and when the reduction plate 8 moves downward, the expansion plate 9 moves upward.

[0033] Vacuum chamber 5 is located directly below ultrasonic chamber 4. The inlet of vacuum chamber 5 is connected to the flow channel hole at the center of the sliding part of expansion plate 9. A vacuum interface is connected to the outer wall of vacuum chamber 5, which is connected to an external vacuum pump (not shown in the figure) via a pipeline for evacuating the interior of vacuum chamber 5. A vacuum sensor (not shown in the figure) is installed on the inner wall of vacuum chamber 5 for real-time monitoring of the vacuum level inside the chamber. An outlet is located at the bottom of vacuum chamber 5, and a control valve 14 is connected to the outlet to control its on / off state.

[0034] Collector 2 is located directly below the outlet of vacuum chamber 5 and is used to collect the gel after the three-stage degassing treatment. Collector 2 is detachably connected to support base 6, which facilitates the removal of the treated gel for subsequent filling or packaging processes.

[0035] In this embodiment, the upper cone angle of the reducing plate 8 is 45°, and the baffle 10 forms eight guide grooves on the cone surface of the reducing plate 8. Each guide groove has a depth of 3mm and a width of 5mm, and the eight guide grooves are evenly distributed circumferentially along the cone surface. The lower cone angle of the expanding plate 9 is 60°, and the radial width of the spiral annular flow channel is 10mm, with three spiral turns. The ultrasonic generating device in the ultrasonic chamber 4 uses four ultrasonic transducers with a frequency of 28kHz and a power of 200W each, symmetrically installed in pairs on opposite inner walls of the ultrasonic chamber 4. The heating element in the ultrasonic chamber 4 is set to a heating temperature of 35~45℃. The working pressure of the pressurized chamber 3 is 0.3~0.5MPa, and the working vacuum degree of the vacuum chamber 5 is 100~500Pa.

[0036] The specific implementation process is as follows:

[0037] When using this gel degassing auxiliary device, first open the cover at the upper interface of the pressurized chamber 3, connect the pressurized input pump pipeline to the interface, and start the pressurized input pump to deliver the gel containing bubbles into the pressurized chamber 3 under pressure. After the gel enters the pressurized chamber 3, the internal bubbles collapse and rupture under the pressure difference between the inside and outside of the chamber under high pressure, completing the first stage of pressurized degassing. The pressure sensor inside the pressurized chamber 3 monitors the pressure inside the chamber in real time and maintains it within the preset working pressure range.

[0038] The pressurized gel is ejected from the outlet under pressure and its own gravity, entering the ultrasonic chamber 4. During its descent, the gel impacts the upper tip of the constriction plate 8 and spreads evenly along the guide grooves on the conical surface of the constriction plate 8, forming a thin film of fluid. This significantly increases the surface area of ​​the gel, exposing the encapsulated air bubbles to the surface. The ultrasonic generator and heating element are activated, and the ultrasonic transducer generates high-frequency mechanical vibrations within the ultrasonic chamber 4. Utilizing cavitation and mechanical vibration, these vibrations cause the air bubbles inside the gel to coalesce, grow, or loosen. The heating element heats the gel to a preset temperature to reduce its viscosity, facilitating the conduction of the ultrasonic cavitation effect and the escape of the air bubbles.

[0039] Simultaneously, the control center drives the first and second motors 12 to operate. The first eccentric cam pushes the connecting seat 11 and the diameter-reducing plate 8 to reciprocate, while the second eccentric cam 13 pushes the diameter-expanding plate 9 to reciprocate. The diameter-reducing plate 8 and the diameter-expanding plate 9 always move in opposite directions. The reciprocating motion of the diameter-reducing plate 8 causes the landing point of the gel on the conical surface to continuously change, resulting in more uniform spreading. The counter-movement of the diameter-reducing plate 8 and the diameter-expanding plate 9 causes the axial distance between them to change periodically. When the distance decreases, the gel is subjected to compression and shearing between the two plates, further exposing air bubbles from the gel matrix. When the distance increases, the gel obtains more space for spreading, which is beneficial for bubble exposure and ultrasonic action. This completes the second stage of ultrasonic vibration degassing.

[0040] The gel flowing down from the reducing plate 8 enters the spiral annular flow channel of the expanding plate 9 and flows downward along the spiral flow channel. The spiral flow channel prolongs the flow path and residence time of the gel in the ultrasonic chamber 4, allowing the bubbles sufficient time to coalesce, grow, or loosen under the effects of ultrasonic cavitation and mechanical vibration.

[0041] The gelling agent enters the vacuum chamber 5 through the flow channel hole at the center of the sliding part of the expansion plate 9. The vacuum pump continuously evacuates the vacuum chamber 5 through the vacuum interface, maintaining a negative pressure environment inside the chamber. Under the action of vacuum negative pressure, the pressure difference between the inside and outside of the bubble after pressurization and ultrasonic treatment increases sharply, causing the bubble to expand rapidly, float to the surface, and burst, completing the third stage of vacuum degassing.

[0042] After all three stages of degassing are completed, open the control valve 14 at the bottom outlet of vacuum chamber 5. The treated bubble-free gel flows into collector 2 under gravity. Remove collector 2 to obtain the degassed gel product. After one batch is processed, close control valve 14 and the solenoid valve at the outlet of pressurized chamber 3. The pressurized input pump can then be restarted to deliver the gel to be processed into pressurized chamber 3 to begin the next batch processing.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
