A vibration-assisted fine particle size homogenizer

Abstract

This utility model discloses a vibration-assisted fine particle homogenizer, belonging to the technical field of homogenizers. It includes a barrel body, with a guide plate fixedly connected to the inner wall of the barrel body. A vibration mechanism is installed inside the guide plate to vibrate the solution. A support shell is fixedly connected to the lower part of the barrel body, with a power mechanism installed on the inner wall of the support shell and a circulation mechanism installed on the upper part of the support shell. This utility model has a reasonable design structure. It uses the power mechanism to provide power, creating an up-and-down circulation effect for the solution. The guide plate guides the solution flowing back from the upper part, forcing the solution to concentrate towards the center and flow downwards along the annular channel, closely following the vibration mechanism. This avoids energy attenuation due to the solution moving away from the vibration source, thus solving the problem that in existing containers, the homogenization effect is usually more uniform in the center, while the effect may be poor or unstable near the inner wall due to energy attenuation or reflection interference.

Description

Technical Field

[0001] This utility model relates to the technical field of homogenizers, specifically a vibration-assisted fine particle size homogenizer. Background Technology

[0002] A homogenizer is a machine that can mix experimental samples and solutions or solvents evenly to achieve a homogeneous state. It is widely used in biomedicine, petrochemicals, food industry and other fields. Among them, ultrasonic homogenizers use the energy of ultrasound to make the sample vibrate strongly and create cavitation effects near the probe, thereby achieving emulsification, homogenization and dispersion of fine particles.

[0003] Existing ultrasonic homogenizers typically use a vibrating head made of high-strength, high-toughness materials such as titanium alloy. One end of the vibrating head is connected to the ultrasonic generator (transducer) of the equipment, while the other end is directly immersed in the solution to be treated. During operation, the ultrasonic generator converts electrical energy into high-frequency mechanical vibration (frequency usually between 15kHz and 100kHz), which is then transmitted to the solution through the vibrating head to vibrate the solution.

[0004] However, the energy generated by the ultrasonic vibrator propagates in the solution in the form of longitudinal waves, and its intensity decreases with increasing distance. Existing methods generally use the vibrator to vibrate the solution in a container. The energy distribution around the vibrator is characterized by "strong in the center and weak at the edge". Therefore, the homogenization effect in the middle of the container is usually more uniform, while the effect may be poor or unstable in the area near the inner wall due to energy attenuation or reflection interference. To address these issues, we provide a vibration-assisted fine particle size homogenizer. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This invention proposes a vibration-assisted fine particle size homogenizer. By setting up a power mechanism and guide plate, it solves the problem that the homogenization effect in the middle of the existing container is usually more uniform, while the effect may be poor or unstable in the area near the inner wall due to energy attenuation or reflection interference.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a vibration-assisted fine particle homogenizer, comprising a barrel body, a guide plate fixedly connected to the inner wall of the barrel body, and a vibration mechanism disposed inside the guide plate for vibrating the solution; a support shell fixedly connected to the lower part of the barrel body, a power mechanism disposed on the inner wall of the support shell, and a circulation mechanism disposed on the upper part of the support shell to facilitate the vertical circulation of the solution; the diameters at the upper and lower ends of the guide plate are larger than the diameter at the middle part to guide the flowing solution and simultaneously cause the solution to flow near the vibration mechanism.

[0009] Furthermore, the vibration mechanism includes an ultrasonic generator, which is installed on the top of the barrel. A vibrating rod is connected to the lower end of the ultrasonic generator, and the vibrating rod is inserted into the guide plate without contacting the guide plate.

[0010] Furthermore, the power mechanism includes an electric motor, which is fixedly mounted on the lower surface of the support shell, and the output end of the electric motor passes through the support shell and is connected to a first gear.

[0011] Furthermore, a stirring rod is fixedly connected to the upper surface of the first gear, and the stirring rod is located below the guide plate and rotatably connected to the barrel body.

[0012] Furthermore, the circulation mechanism includes a circulation cylinder, with a feed plate fixedly connected to the lower end of the circulation cylinder and a discharge plate fixedly connected to the upper end of the circulation cylinder. The feed plate and the discharge plate are respectively fixedly connected to the lower end and the upper end of the cylinder body.

[0013] Furthermore, the lower end of the circulation cylinder is fixedly connected to the support shell, and a second gear is provided inside the support shell, with the outer surface of the second gear meshing with the first gear.

[0014] Furthermore, a rotating rod is fixedly connected to the upper surface of the second gear.

A helical blade is fixedly connected to the outer surface of the rotating rod, and the outer surface of the helical blade is rotatably connected to the circulation cylinder.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this vibration-assisted fine particle size homogenizer has the following advantages:

[0017] I. This vibration-assisted fine particle homogenizer, through the setting of components such as a power mechanism and a guide plate, provides power to drive the circulation mechanism to move the solution at the bottom of the tank, causing the solution to be injected into the upper part of the tank, forming an up-and-down circulation effect of the solution. The guide plate has a converging and guiding effect on the solution returning from the upper part, forcing the solution to concentrate in the middle and flow downward along the annular channel close to the vibration mechanism. This avoids the energy attenuation of the solution due to the distance from the vibration source, and ensures that each part of the solution can pass through the high-energy vibration area multiple times. This solves the problem that the homogenization effect in the middle of the existing container is usually more uniform, while the effect may be poor or unstable in the area near the inner wall due to energy attenuation or reflection interference.

[0018] II. This vibration-assisted fine particle homogenizer, through the setting of power mechanism and other components, drives the stirring rod to rotate while the first gear rotates. The stirring rod stirs the solution after vibration treatment under the guide, which can break up any local uneven concentration or particle agglomeration in the solution, further mix the preliminarily homogenized solution, and make the overall system more uniform.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The electric motor 501 and the ultrasonic generator 301 in this utility model are common electrical devices in the prior art, and this application will not elaborate on their models or internal structures.

[0028] like Figure 1-5 As shown, this utility model provides a technical solution: a vibration-assisted fine particle size homogenizer, including a barrel 1, a guide plate 2 fixedly connected to the inner wall of the barrel 1, a vibration mechanism 3 installed inside the guide plate 2 for vibrating the solution; a support shell 4 fixedly connected to the lower part of the barrel 1, a power mechanism 5 installed on the inner wall of the support shell 4, and a circulation mechanism 6 installed on the upper part of the support shell 4 to facilitate the vertical circulation of the solution; the diameters at the upper and lower ends of the guide plate 2 are larger than the diameter at the middle part to guide the flowing solution and allow the solution to flow near the vibration mechanism 3; the interior of the barrel 1 is used to hold the liquid, with an inlet at the upper part and an outlet pipe at the lower part for feeding and discharging; and a support component is fixedly installed below the support shell 4. 7. Used to support and fix all components. In use, the solution is poured into the interior of the tank 1. The vibration mechanism 3 vibrates the solution to emulsify and homogenize it. The power mechanism 5 provides power, which drives the circulation mechanism 6 to move the solution at the bottom of the tank 1, causing the solution to be injected into the upper part of the tank 1, forming a downward circulation effect to promote the homogenization of the solution. During the downward flow of the solution, the guide plate 2 guides the solution, causing the solution at the top to concentrate and flow downward. During the downward flow of the solution, the guide plate 2 keeps the solution close to the vibration mechanism 3, thus preventing the solution from being too far away from the vibration mechanism 3 and resulting in poor vibration effect. Combined with the effect of the up and down circulation, uniform vibration of the solution is achieved.

[0029] Vibration mechanism 3 includes an ultrasonic generator 301, which is installed on the top of the tank 1. The lower end of the ultrasonic generator 301 is connected to a vibrating rod 302, which is inserted into the guide plate 2 without contacting the guide plate 2. The vibrating rod 302 and the middle of the guide plate 2 form a downward annular channel with a diameter of 2 to 5 cm, so as to make the solution adhere as closely as possible to the vibrating rod 302 without affecting the upward and downward flow speed.

[0030] The power mechanism 5 includes an electric motor 501, which is fixedly mounted on the lower surface of the support shell 4. The output end of the electric motor 501 passes through the support shell 4 and is connected to a first gear 502. The electric motor 501 can drive the first gear 502 to rotate.

[0031] A stirring rod 503 is fixedly connected to the upper surface of the first gear 502. The stirring rod 503 is located below the guide plate 2 and is rotatably connected to the barrel 1. When the first gear 502 rotates, it can drive the upper stirring rod 503 to rotate, thereby stirring the solution flowing down from the guide plate 2. After the solution is vibrated, the internal particles are broken, and then it is stirred again to enhance its homogenization effect. The position where the stirring rod 503 contacts the barrel 1 is sealed.

[0032] The circulation mechanism 6 includes a circulation cylinder 601. A feed plate 602 is fixedly connected to the lower end of the circulation cylinder 601, and a discharge plate 603 is fixedly connected to the upper end of the circulation cylinder 601. The feed plate 602 and the discharge plate 603 are fixedly connected to the lower end and the upper end of the barrel 1, respectively. The circulation cylinder 601 is connected to the barrel 1 through the feed plate 602 and the discharge plate 603, forming a channel for the solution to move upward, so that the solution falls to the bottom of the barrel 1 and is then transported to the upper part of the barrel 1.

[0033] The lower end of the circulating cylinder 601 is fixedly connected to the support shell 4. The support shell 4 is provided with a second gear 604. The outer surface of the second gear 604 meshes with the first gear 502. When the first gear 502 rotates, it can drive the second gear 604 to rotate.

[0034] A rotating rod 605 is fixedly connected to the upper surface of the second gear 604. The rotating rod 605 is inserted into the inside of the circulation cylinder 601 and rotatably connected to it. A spiral blade 606 is fixedly connected to the outer surface of the rotating rod 605. The outer surface of the spiral blade 606 is rotatably connected to the circulation cylinder 601. The contact point between the rotating rod 605 and the circulation cylinder 601 is sealed. When the second gear 604 rotates, the rotating rod 605 and the spiral blade 606 can be adjusted to rotate, so that the solution is transported upward.

[0035] Working principle: When the solution is injected into the tank 1 through the feed port, the vibration mechanism 3 is activated: the ultrasonic generator 301 converts electrical energy into high-frequency mechanical vibration, which is transmitted to the surrounding solution through the vibrating rod 302. Since the vibrating rod 302 and the middle of the guide plate 2 form an annular channel with a diameter of 2-5cm, the solution is forced to be close to the surface of the vibrating rod 302 when it flows, so that the ultrasonic energy acts on the solution efficiently in the form of longitudinal waves. The cavitation effect and strong vibration break the particles to achieve preliminary emulsification and homogenization.

[0036] The motor 501 drives the first gear 502 to rotate, which in turn drives the second gear 604 to rotate through gear meshing. This causes the rotating rod 605 and the spiral blade 606 inside the circulation cylinder 601 to rotate synchronously. The spiral blade 606 draws the solution from the bottom of the barrel 1 into the circulation cylinder 601 through the feed plate 602 and conveys it upward to the discharge plate 603 at the top of the barrel 1, forming a closed loop of "bottom → top → downward flow". During this process, the guide plate 2, due to its special structure of "large diameter at the top and bottom and small diameter in the middle", has a converging and guiding effect on the solution flowing back from the top: forcing the solution to concentrate in the middle and flow downward along the annular channel close to the vibrating rod 302, avoiding energy attenuation due to the solution being far from the vibration source, and ensuring that each part of the solution can pass through the high-energy vibration area multiple times.

[0037] While the first gear 502 rotates, it drives the stirring rod 503 to rotate. The stirring rod 503 performs secondary stirring on the solution after vibration treatment below the guide plate 2. This can break up any local uneven concentrations or particle agglomeration that may exist in the solution, further mix the initially homogenized solution, and make the overall system more uniform.

[0038] During the circulation process, the solution continuously repeats the process of "upper reflux → guide plate convergence → vibration close to vibrator 302 → stirring and mixing → bottom recirculation" until the solution in all areas has been fully ultrasonically treated and mixed. Finally, the homogenized solution can be discharged through the discharge pipe at the bottom of the tank 1.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
