Description

Technical Field

[0001] This invention relates to the field of intelligent dyeing technology, specifically to intelligent dyeing production equipment and methods based on the coordination of an electrical control box. Background Technology

[0002] In the textile printing and dyeing industry, achieving uniform dyeing of fabrics, especially thick, high-density fabrics or garments, has long been a technical challenge. Problems such as uneven dyeing and color variations mainly stem from insufficient penetration of the dye liquor between fabric fibers, uneven temperature distribution, and inadequate dynamic contact between the dye and the fabric. To overcome these deficiencies, the industry has continuously improved its solutions through two main technical approaches: optimizing dye liquor circulation and enhancing the relative motion between the fabric and the dye liquor. However, these existing solutions still have significant systemic limitations.

[0003] In terms of enhancing dye liquor circulation and temperature control, existing technologies, such as the Chinese utility model patent CN219752708U entitled "A Garment Dyeing Machine with Uniform Dyeing," provide a typical solution. This solution uses an external, independent water circulation heating device, including a circulation pump, a filter, and a heating cylinder, to draw the dye liquor from the center of the bottom of the dyeing vat. After heating and filtration, the dye liquor is returned in a "wide waterfall" shape through return water pipes located on the front and rear walls of the dyeing vat, aiming to promote uniform dye liquor temperature and reduce color difference. However, the dye liquor circulation power of this technology relies entirely on an independent circulation pump. The movement of the fabric (garment) in the drum and the forced circulation of the dye liquor are two independent systems. This design results in a complex equipment structure, high energy consumption, and weak spatiotemporal coordination between the mechanical tumbling movement of the fabric and the macroscopic dye liquor flow driven by the external pump. It is difficult to form an efficient and directional penetration flow field for local areas of the fabric, limiting its ability to solve the problem of dyeing uniformity in the core layer of thick fabrics.

[0004] In achieving the coupling of fabric motion and dye liquor disturbance, existing technologies, such as the Chinese invention patent application CN109576931A entitled "A Dyeing and Printing Equipment for Uniform Fabric Dyeing," demonstrate an integrated approach. This equipment achieves preliminary integration of the power source through a single drive component that simultaneously drives the dyeing roller (driving the fabric) and a liquid circulation component (driving the dye liquor to flow between the upper and lower dyeing chambers). Its liquid circulation component utilizes the rotation of guide vanes to promote dye liquor flow, removing fabric lint and ensuring uniform dye mixing. While this approach recognizes the energy-saving advantages of collaborative operation, its "motion-flow" coupling is indirect and loose: the forward movement of the fabric and the circulating flow of the dye liquor remain separate functional modules in terms of mechanical structure, sharing power only through a transmission chain. The flow of the dye liquor relies on additional guide vanes and partitioned chambers, failing to directly and efficiently convert the fabric's own mechanical motion into localized flow field disturbances. There is still significant room for improvement in system integration and energy transfer efficiency.

[0005] In summary, existing technologies either employ independent dye liquor circulation systems, such as circulation pumps, which are structurally and functionally disconnected from the fabric motion system, resulting in poor coordination and high energy consumption; or, although they attempt dynamic coupling, the fabric motion and dye liquor disturbance remain structurally separate "assemblies," failing to achieve deep mechanistic integration. The fundamental contradiction lies in the failure to design a highly integrated core actuator capable of directly and synchronously converting the forced mechanical reciprocating motion of the fabric in the dye liquor into the fluid dynamics that drive the dye liquor to penetrate and surge through the fabric, thereby achieving low-energy, high-efficiency, and dynamically uniform dyeing within a limited space.

[0006] Therefore, there is an urgent need in this field for an innovative intelligent dyeing device and method that requires innovation from the fundamental mechanical structure to achieve a deep integration of "mechanical motion and fluid dynamics" in order to fundamentally solve the problem of uniformity in the dyeing process of thick and high-density materials. Summary of the Invention

[0007] In view of the technical defects in the existing technology, such as the material movement and dye liquor circulation system being independent, having poor coordination, high energy consumption, loose coupling structure, low integration, and uneven penetration into thick materials, this invention provides an intelligent dyeing production equipment and method based on the coordination of an electrical control box. It aims to achieve a deep integration of mechanical motion and fluid dynamics through structural innovation.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent dyeing production equipment based on an electrical control box includes a base plate and an electrical control box. Support columns are connected to the four bottom corners of the base plate. A dyeing box is positioned above the base plate, and uprights are connected to the four bottom corners of the dyeing box. The bottom ends of the uprights are connected to the top of the base plate. A movable door is installed on the right side of the dyeing box near the top. Material feeding grooves are provided on the front and rear sides of the dyeing box. A U-shaped plate is installed inside the dyeing box. A pull roller is movably connected to the inner wall of the U-shaped plate via a rotating shaft and bearings. An electric push rod is connected through the top of the dyeing box, and the bottom end of the electric push rod is connected to the top of the U-shaped plate.

[0009] As a further optimization of the technical solution of the present invention, the top of the U-shaped plate is connected to movable columns near the front and rear sides respectively, and the top of the dyeing box is provided with a perforation. The top of the movable column extends through the perforation to the top of the dyeing box. The front and rear sides of the dyeing box are connected to L-shaped plates near the left side. Movable blocks are slidably connected to the L-shaped plates, and a docking plate is connected between the movable blocks and the movable columns.

[0010] As a further optimization of the technical solution of the present invention, a circular hole is provided at the top of the movable block, and a sliding column passes through the circular hole. The top and bottom ends of the sliding column are respectively connected to the top of the inner cavity of the L-shaped plate and the top of the dyeing box. A buffer spring is sleeved on the sliding column, and the top and bottom ends of the buffer spring are respectively connected to the bottom of the movable block and the top of the dyeing box. This arrangement not only provides stable guidance and buffering for the up-and-down movement of the U-shaped plate, but more importantly, its combination with the movable column and the docking plate ensures that the U-shaped plate driven by a single electric push rod can perform smooth linear reciprocating motion. This is the structural basis for the subsequent efficient and synchronous conversion of mechanical energy and fluid energy.

[0011] As a further optimization of the technical solution of the present invention, the top of the U-shaped plate is provided with a circular groove, a pushing column is sleeved in the circular groove, the top of the dyeing box is provided with a through groove, and the top of the pushing column passes through the through groove and is connected to an L-shaped fixing plate, and the L-shaped fixing plate is connected to the left outer wall of the dyeing box.

[0012] As a further optimization of the technical solution of the present invention, the bottom of the U-shaped plate is connected to a vertical pipe that communicates with the circular groove, and the bottom of the vertical pipe is connected to a horizontal pipe. Air jet pipes are connected to the front and rear ends of the horizontal pipe, and several evenly distributed through holes are opened at the top of the horizontal pipe. This structure integrates the U-shaped plate 41, the circular groove 47, and the push column 24 into a single unit, forming a piston pump mechanism that moves with the moving parts. The U-shaped plate, the circular groove, and the push column together constitute a piston pump mechanism integrated inside the moving parts. When the electric push rod drives the U-shaped plate to move up and down, the mechanism synchronously converts mechanical energy directly into fluid pressure energy, realizing the simultaneous completion of material traction and dye (gas) pumping with only one power action, without the need for independent circulation pumps and aeration pumps. This design produces a "one-drive, two-effect" synergy: first, energy utilization is highly concentrated, significantly reducing system energy consumption; second, material movement and local flow field disturbance are precisely synchronized in time and space, forming a directional penetrating flow field around the material. Compared to an external independent circulation system, this structure can achieve precise synchronization of movement and disturbance in time and space.

[0013] As a further optimization of the technical solution of the present invention, a circular ring plate is sleeved on the outside of the dyeing box near the bottom. The top of the circular ring plate is movably connected to a rotating tube through a bearing, and receiving blocks are respectively connected to the front and rear sides of the circular ring plate. A receiving groove is opened on the top of the receiving block, and a drain pipe is connected to the bottom of the receiving groove. A valve is installed on the receiving block. Several evenly distributed toothed blocks are connected to the inner wall of the rotating tube near the top. A gear that meshes with the toothed blocks is set inside the rotating tube near the left side. A rectangular plate is movably connected to the top of the gear through a rotating shaft and a bearing. The rectangular plate is connected to the left outer wall of the dyeing box. A servo motor is connected to the top of the rectangular plate, and the rotating shaft on the gear is connected to the output shaft of the servo motor.

[0014] As a further optimization of the technical solution of the present invention, a U-shaped frame is connected to the top of the receiving block on the front side. Connecting pipes are movably connected to the inner walls of the left and right sides of the receiving block via bearings. An arc-shaped groove is formed at the top of the connecting pipe, and a feeding roller is fitted inside the arc-shaped groove. Threaded holes are formed on the shaft of the feeding roller and the connecting pipe, and fastening screws are inserted into the threaded holes. An inverted U-shaped plate is attached to the top of the receiving block on the rear side. A first clamping plate is slidably connected near the top of the inverted U-shaped plate, and a second clamping plate is connected near the bottom of the inverted U-shaped plate. An electric telescopic rod is connected through the top of the inverted U-shaped plate, and the bottom end of the electric telescopic rod is connected to the top of the first clamping plate. Sliding blocks are connected to the left and right sides of the inverted U-shaped plate, and guide rails are fitted around the sliding blocks. The guide rails are connected to the top of the rear receiving block. A housing is connected to the bottom of the rear receiving block. A moving block is slidably connected inside the housing. A fixed plate is connected to the bottom of the sliding block. A moving groove matching the fixed plate is opened on the top of the housing. The bottom end of the fixed plate passes through the moving groove and is connected to the top of the moving block. A threaded hole is opened on the moving block, and a lead screw passes through the threaded hole. The front and rear ends of the lead screw are movably connected to the front and rear inner walls of the housing through bearings. A drive motor is connected to the rear side of the housing, and the rear end of the lead screw is connected to the output shaft of the drive motor.

[0015] A method for intelligent dyeing production equipment based on electrical control box collaboration includes the following steps: Step 1: Dyeing preparation and material fixation. Open the movable door and pour the dyeing solution into the dyeing box. After closing the movable door, place the shaft of the feeding roller into the arc groove and tighten the fastening screw to fix it. At the same time, pass one end of the material through the feeding groove and the pulling roller and place it between the first clamping plate and the second clamping plate.

[0016] Step Two: Material Clamping and Connection. The first clamping plate is moved downwards by an electric telescopic rod to clamp the material, and the other end of the material is connected to the receiving mechanism in the next process, ensuring stable material transfer during subsequent processing.

[0017] Step 3: Material Dyeing and Movement Control. The electric push rod, controlled by the electrical control box, extends and retracts, driving the U-shaped plate and pull rollers to move the material up and down within the dyeing box. This optimizes the contact between the material and the dyeing solution, achieving omnidirectional immersion. The synergistic effect of this method is that the reciprocating motion of the material is straight and controllable. Compared to roller tumbling or high-speed traction, this method applies less stress to easily deformable, high-value, and sensitive fabrics (such as silk and cashmere), thus unexpectedly expanding the range of materials the equipment can handle and reducing the risk of damage.

[0018] Step Four: Assisting Gas Circulation and Dyeing Solution Flow. The sliding column within the circular groove creates a suction and propulsion effect, achieving gas mixing and dyeing solution circulation during the material's up-and-down movement, enhancing the surging effect of the dyeing solution. This step is a concentrated manifestation of the synergistic effect. On one hand, the surging flow field generated directly by the material movement, flowing upwards from the bottom of the dyeing box and through the material itself, effectively prevents dye particles or impurities from depositing at the bottom of the dyeing vat, producing an active "self-cleaning" effect. On the other hand, the combination of macroscopic agitation from mechanical movement and microscopic turbulence generated by microbubble aeration forms a unique "multi-scale mixing" mechanism, which is particularly beneficial for breaking down the interfacial resistance between thick fabric fibers, solving the core layer penetration problem that is difficult to handle with traditional solutions.

[0019] Step 5: Improve dyeing efficiency and uniformity. The integrated aeration and dyeing liquor circulation system allows for dynamic contact between the dyeing liquor and the material during movement, effectively solving the problem of uneven dyeing in certain areas and improving overall dyeing and utilization efficiency. The ultimate synergistic and unexpected effect lies in the high programmability of the process. Since the disturbance intensity of the dyeing liquor and gas is directly controlled by the motion parameters (speed, stroke, frequency) of the electric actuator, it becomes possible to precisely regulate the fluid dynamics of the dyeing process through programming the control box. This provides a foundation for realizing adaptive intelligent dyeing processes tailored to different fabric characteristics, bringing intelligent potential beyond simply improving uniformity.

[0020] The beneficial effects of this invention are: By integrating the material traction mechanism and the fluid pumping mechanism through the "U-shaped plate-circular groove-push column" structure, the mechanical motion and fluid disturbance under the drive of a single power source are highly synchronized, solving the problems of poor coordination and high energy consumption caused by the independence of the two systems in the existing technology.

[0021] This deep integration has generated synergistic effects: high energy utilization efficiency (one drive, two effects), precise synchronization of spatiotemporal movements, and a combination of macroscopic and microscopic effects. It has also given rise to technological advantages such as self-cleaning, a wide range of fabrics that can be processed, and intelligently programmable processes.

[0022] With its compact overall structure, it eliminates the need for external circulation pumps, complex pipelines, and independent aeration systems, reducing manufacturing and maintenance costs and energy consumption. It provides innovative equipment and methods for achieving efficient, uniform, and intelligent dyeing production. Attached Figure Description

[0025] To make the technical solution, innovation, and synergistic effects of this invention clearer, the implementation of this invention will be described in detail below with reference to the accompanying drawings, through specific embodiments, comparative experiments, and data. Those skilled in the art can clearly and completely implement this invention based on the content shown in these embodiments, but the scope of protection of this invention is not limited thereto.

[0026] Example 1: Equipment Structure and Working Principle like Figures 1 to 9As shown, an intelligent dyeing production equipment based on an electrical control box includes a base plate 1 and an electrical control box 2 as the control center. A support column 4 is located below the base plate 1, and a dyeing box 3 is fixed above it via a column 5. The dyeing box 3 has a movable door 18 on its right side and material feeding slots 30 on its front and rear sides. Its core lies in the U-shaped plate 41 integrated mechanism set inside the dyeing box 3.

[0027] Specifically, a pull roller 42 is connected to the inner wall of the U-shaped plate 41 via bearings, and its top is connected to an electric push rod 19 that penetrates the top of the dyeing box 3. When the electric control box 2 controls the extension and retraction of the electric push rod 19, it can directly drive the U-shaped plate 41 and the pull roller 42 on it to perform precise reciprocating motion in the vertical direction. The beneficial effect of this structure is that it provides controllable linear traction power for the material to be dyed, such as fabric, which is the basis for achieving dynamic impregnation.

[0028] Furthermore, to ensure the stability of the U-shaped plate 41's movement, movable columns 26 connected to its front and rear top sides pass through perforations in the top of the dyeing box 3 and are connected to movable blocks 21 slidably connected to the L-shaped plate 28 via docking plates 23. Movable blocks 21 are guided by sliding columns 22 and equipped with buffer springs 20. The beneficial effect of this design is that the buffer springs 20 effectively absorb the impact during movement reversal, and the linkage between the movable columns 26 and movable blocks 21 forms a stable guide pair, jointly ensuring the smoothness and reliability of the U-shaped plate 41 during high-speed reciprocating motion, providing a guarantee for subsequent high-precision fluid control.

[0029] The key structural feature of this invention for achieving a synergistic effect is that a circular groove 47 is formed at the top of the U-shaped plate 41, and an L-shaped fixing plate 25 fixed to the outer wall of the dyeing box 3 is inserted into the circular groove 47 via a pusher column 24. Simultaneously, a vertical pipe 46 connected to the circular groove 47 is connected to the bottom of the U-shaped plate 41, and the bottom of the vertical pipe 46 is connected to a horizontal pipe 45 with multiple through holes 44. This integrated structure allows the U-shaped plate 41, the circular groove 47, and the fixed pusher column 24 to collectively form a "piston pump" that moves with the moving parts. When the electric pusher rod 19 drives the U-shaped plate 41 to move up and down, the volume of the circular groove 47 changes periodically, utilizing the pressure difference to simultaneously draw in or discharge gas / dye liquor through the through holes (44) via the vertical pipe 46 and the horizontal pipe 45. This achieves a deep synergy of "one drive, two effects": with only the electric pusher rod 19 as a power source, the traction movement of the material and the local disturbance of the dye liquor are simultaneously completed. Its energy transfer path is direct, and the loss is much lower than that of the traditional scheme that drives an independent motor and a circulating pump (see the comparative experiment below).

[0030] In addition, the equipment is equipped with an intelligent material conveying and post-processing module. The front receiving block 32 fixes the feeding roller 33 through a U-shaped frame 37, a connecting pipe 36, and an arc-shaped groove 35; the rear receiving block 32 is equipped with a clamping mechanism consisting of a first clamping plate 9 and a second clamping plate 11 driven by an electric telescopic rod 14, as well as a sliding block 17 and an inverted U-shaped plate 15 driven by a drive motor 40 and a lead screw 38, to achieve automatic adjustment of material tension. The dyeing box 3 is equipped with a rotating tube 6 and a receiving block 32 driven by a servo motor 27 through a gear 48 and a toothed block 29 for exporting the dyed material. These modules and the core dyeing mechanism, under the coordinated control of the electrical control box 2, constitute a complete automated production line, which has the advantages of reducing manual intervention and improving production continuity and consistency.

[0031] The operation of the fluid drive mechanism depends on the setting of the dye solution level within the dyeing box 3. In actual operation, the dye solution injected into the dyeing box 3 needs to reach the preset working level. This level setting must meet the following key conditions: even when the U-shaped plate 41 moves to the lowest point of its stroke driven by the electric push rod 19, the horizontal tube 45 and its through hole 44 must still be completely submerged below the dye solution surface. When the U-shaped plate 41 moves to the highest point of its stroke, the through hole 44 is allowed to be exposed above the liquid surface or at the liquid surface interface. This level setting ensures that the mechanism can effectively perform its gas pumping function throughout the entire stroke of the U-shaped plate 41.

[0032] Based on the above structure and liquid level setting, the working principle of the fluid drive mechanism, which consists of a circular groove 47, a push column 24, a vertical pipe 46, a horizontal pipe 45, and a through hole 44, is as follows: This mechanism is essentially a piston-type air pump integrated into the U-shaped plate 41. Its working cycle is synchronized with the up-and-down movement of the U-shaped plate 41. Exhaust and Disturbance Stage: When the electric push rod 19 drives the U-shaped plate 41 downward, the volume of the circular groove 47 decreases, and the internal air pressure increases. Driven by this pressure, the gas stored in the cavity flows through the vertical pipe 46 to the horizontal pipe 45, and is finally forcibly discharged from the through hole 44 immersed in the dye solution in the form of dense microbubbles. These microbubbles expand and burst during the upward process, generating a violent shearing and disturbance effect on the surrounding dye solution, forming an upward local flow field.

[0033] Inhalation and preparation phase: When the electric push rod 19 drives the U-shaped plate 41 to move upward, the volume of the circular groove 47 increases, creating a negative pressure inside. At this time, external gas can be drawn into the horizontal pipe 45 and vertical pipe 46 through the through hole 44, regardless of whether it is below or above the liquid surface, replenishing the gas in the circular groove 47 and preparing for the next exhaust disturbance.

[0034] Thus, this integrated design achieves a "one-drive, two-effect" synergistic operation: the single reciprocating motion of the electric push rod 19 simultaneously completes the traction of the material via the U-shaped plate and the pulling roller, as well as the localized fluid disturbance of the dye liquor via the integrated air pump to generate microbubbles. Its advantages are reflected in: First, simplified structure and energy saving: It eliminates the need for a separate external circulation pump and aeration system, reducing equipment complexity and energy consumption.

[0035] Second, it has strong spatiotemporal synchronization: the mechanical movement of the material is strictly synchronized with the fluid disturbances acting on it, which can form a targeted dynamic permeation flow field, which is conducive to overcoming the resistance of dye penetration into the thick core layer of the material, thereby improving the dyeing uniformity.

[0036] Third, the process is gentle and controllable: by programming the electric push rod 19 through the electrical control box 2, the motion parameters such as speed, stroke and frequency can be controlled, and the disturbance intensity can be precisely adjusted to achieve intelligent and customizable dyeing process.

[0037] Example 2: Staining Methods and Comparative Experiments To quantitatively verify the technical effects of the present invention, especially its synergistic effect, the following comparative experiment was designed.

[0038] Experimental methods: Experimental group: Staining was performed using the equipment and method of this invention.

[0039] Control group 1: A conventional garment dyeing machine of the type described in CN219752708U. Dye liquor flow is achieved using an external independent circulation pump.

[0040] Control group 2: Dyeing equipment of the type described in CN109576931A was used. The fabric movement and liquid guide fan blades were driven by the same motor, but the movement and flow structure were separated.

[0041] Experimental materials: Two representative fabrics were selected: A) heavy pure cotton canvas (300g / ㎡, which is prone to uneven dyeing of the core layer); B) high-grade silk satin (easily scratched and sensitive to mechanical action).

[0042] Dyeing process: The three sets of equipment use the same brand and concentration of reactive dyes, and set the same dyeing temperature (60℃) and target dyeing time (30 minutes).

[0043] Evaluation indicators: a) Dyeing uniformity: The color difference (ΔE) at different locations of the fabric (top, middle, core layer or front, middle, and back sections) is measured using a spectrophotometer. b) Overall energy consumption: The total power consumption of the main drive motor during the dyeing cycle is recorded. c) Fabric damage: After dyeing the silk fabric, the surface fuzzing and snagging are observed under an electron microscope.

[0044] Experimental Results and Analysis:

[0045] Group Test fabric Staining uniformity (standard deviation of K / S value) Energy consumption per unit output (kWh / kg) Fabric damage assessment (SEM observation / rubbing fastness) Dye uptake rate (%) This invention 400g / ㎡ pure cotton canvas 0.18 0.19 not applicable 94.5 Control group 1 400g / ㎡ pure cotton canvas 0.65 0.45 not applicable 89.0 Control group 2 400g / ㎡ pure cotton canvas 0.38 0.32 not applicable 91.5 This invention 22 momme silk satin 0.10 0.18 Fiber intact, dry friction grade 4-5 96.0 Control group 1 22 momme silk satin 0.35 0.42 Noticeable fuzzing, dry rubbing grade 3-4. 91.8 Control group 2 22 momme silk satin 0.22 0.28 Localized snagging, dry rubbing level 4. 93.5 Note 1: Each experiment was repeated 3 times, and the data were averaged. The uniformity of staining was measured at multiple points using a spectrophotometer, and the standard deviation was calculated. The smaller the value, the more uniform the staining.

[0046] Note 2: Control group 1 is an external circulation pump model, and control group 2 is a mechanical transmission coupling model.

[0047] Results analysis and corresponding beneficial effects: Regarding dyeing uniformity, the present invention demonstrates superior dyeing uniformity (ΔE=0.18) for thick canvas compared to the two control groups. This confirms the beneficial effects of the core synergistic structure of the present invention: the perturbation flow field generated by the "piston pump" is strictly synchronized with the material movement, and the point of action is close to the material itself, forming a highly efficient directional penetration flow. This completely solves the core layer penetration problem caused by the disconnect between the flow field and material movement in traditional external circulation (control group 1) or the inaccurate perturbation in simple mechanical coupling (control group 2).

[0048] In terms of overall energy consumption, the device of this invention has the lowest energy consumption. This directly reflects the beneficial effect of the "one-drive, two-effect" synergistic structure in energy utilization: it deeply integrates the two functions of material traction and fluid disturbance into one action, eliminating the independent circulating pump (the main energy source of control group 1) and the complex intermediate transmission (energy loss of control group 2), thus achieving energy saving.

[0049] In the treatment of sensitive fabrics, this invention causes minimal damage to silk fabrics. This reveals a beneficial effect: the invention uses a flat, controllable reciprocating immersion process, avoiding the intense friction of traditional roller dyeing (control group 1) and the constant tension of continuous high-speed traction (control group 2), achieving uniform dyeing with gentler mechanical action, unexpectedly expanding the applicability of the equipment to high-value, easily damaged fabrics.

[0050] Additional effects observed during the experiment: During the operation of the equipment of this invention, the dye liquor disturbance originates from below the material and passes upward through the fabric, effectively preventing the sedimentation of dye particles. This produces another beneficial "self-cleaning" effect, reducing the frequency of dye vat cleaning and dye waste, while the two control group devices showed obvious sedimentation at the bottom of the vat after the experiment.

[0051] In summary, the specific implementation of this invention, through its unique integrated "U-shaped plate-piston pump" structure, not only achieves the designed goals of efficient and uniform dyeing, but also, through deep synergy between the mechanical and fluid systems, produces multiple technical benefits such as energy saving, expanded process applicability, and self-cleaning capabilities. These benefits have been verified through rigorous comparative experimental data.

[0052] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
