Description

Technical Field

[0001] This utility model relates to the field of hydrogel production, and in particular to a mixing reaction apparatus for preparing deodorizing and bactericidal hydrogels. Background Technology

[0002] Hydrogels are a type of highly hydrophilic three-dimensional network structure gel that swells rapidly in water and retains a large volume of water without dissolving in this swollen state. As a highly absorbent and water-retaining material, hydrogels are widely used in various fields, such as: drought relief in arid regions; cosmetics (face masks, fever-reducing patches, analgesic patches), agricultural films; condensation prevention agents and humidifiers in construction; water-blocking agents in petrochemicals; dehydration of crude oil or refined oil products; dust suppressants in mining; preservatives and thickeners in food; and drug carriers in medicine, etc.

[0003] Deodorizing and antibacterial hydrogels are a special type of hydrogel used for inhibiting bacteria and decomposing odors. Compared to the preparation of ordinary hydrogels, deodorizing and antibacterial hydrogels require the addition of functional additives (bactericides and deodorizers). This means that if conventional hydrogel reaction equipment is used for preparation, the mechanical shear force generated by the stirring blades can easily damage the functional additives (especially heat-sensitive bactericides, probiotics, enzymes, nano-encapsulations, etc.) due to the "local imbalance of energy input" and "high stress concentration at the microscale," thus affecting product quality. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a mixing reaction device for preparing deodorizing and bactericidal hydrogels, which aims to avoid damage to additives by mechanical shear force and improve product quality.

[0005] To achieve the above objectives, this utility model provides a mixing reaction apparatus for preparing deodorizing and bactericidal hydrogels. The mixing reaction apparatus includes: a reaction vessel body, a cover, and an ultrasonic radiation rod array; the reaction vessel body has a hemispherical bottom at its lower part, a base is provided below the hemispherical bottom, and a discharge port is provided on the hemispherical bottom; the cover is connected to the top of the reaction vessel to seal the top of the reaction vessel, and the cover has at least one inlet, with a motor mounting inlet at its center; the ultrasonic radiation rod array includes a first mounting mechanism, on which a plurality of first mounting holes are arrayed, and ultrasonic radiation rods are installed in the first mounting holes. The ultrasonic radiation rods are used to stir and mix materials by ultrasonic vibration. The ultrasonic radiation rod array also includes a first motor, which is connected to the first mounting mechanism through the motor mounting inlet. The first motor is used to rotate the first mounting mechanism to change the distribution position of each ultrasonic radiation rod.

[0006] Optionally, a jacket is provided on the outside of the reactor body, and a heater is provided in the jacket. The heater is used to heat the reactor body, and the jacket is used for heat preservation.

[0007] Optionally, the feed inlet is connected to a tangential jet nozzle array via a pipe. The tangential jet nozzle array is located at the bottom of the reactor body and includes multiple tangential jet nozzles. The tangential jet nozzles are used to add materials during the reaction process to form a tornado-like vortex.

[0008] Optionally, a temperature sensor is also installed inside the reactor body to monitor the real-time temperature during the reaction process, and then control the heating temperature based on the real-time temperature.

[0009] Optionally, the reactor body is also provided with a vacuum interface, which is connected to a vacuum pumping device. The vacuum pumping device is used to draw a vacuum before gelation to remove dissolved air and bubbles entrained by stirring.

[0010] Optionally, a near-infrared spectral sensor is also provided inside the main body of the reactor, which is used to detect the uniformity of the concentration distribution of the bactericide.

[0011] Optionally, the inlet includes a solid material inlet for solid materials and a liquid material inlet for liquid materials.

[0012] The beneficial effects of this invention are as follows: 1. This invention uses an ultrasonic radiant rod array instead of traditional stirring blades to stir materials, achieving zero mechanical shear damage, avoiding loss of functional additives, and improving product quality. 2. The ultrasonic radiant rod array of this invention is connected to a first motor, which is used to rotate the first mounting mechanism to change the distribution position of each ultrasonic radiant rod, avoiding the problem that the material mixing uniformity is worse in areas further away from the ultrasonic radiant rods due to the fixed position of the ultrasonic radiant rod array.

[0013] In summary, this invention avoids the damage to additives caused by the mechanical shearing force generated by traditional stirring, and makes the materials more uniformly mixed, thus improving product quality. Attached Figure Description

[0017] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0018] In the description of this patent, it should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this patent 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 patent.

[0019] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0020] The applicant's research revealed that deodorizing and antibacterial hydrogels are a special type of hydrogel used for antibacterial and odor decomposition. Compared to the preparation of ordinary hydrogels, deodorizing and antibacterial hydrogels require the addition of functional additives (bactericides and deodorizers). This means that if conventional hydrogel reaction equipment is used for preparation, the mechanical shear force generated by the stirring blades can easily damage the functional additives (especially heat-sensitive bactericides, probiotics, enzymes, and nano-encapsulations) due to the "local unevenness of energy input" and "high stress concentration at the microscale," thus affecting product quality. Using an ultrasonic radiant rod array can replace traditional stirring blades for stirring, effectively avoiding the damage caused by mechanical shear force. However, because the ultrasonic radiant rod array has a fixed position, the material mixing uniformity decreases further away from the ultrasonic radiant rods.

[0021] Therefore, this utility model embodiment provides a mixing reaction apparatus for preparing deodorizing and bactericidal hydrogels, such as... Figure 1-3As shown, the mixing reaction device includes: a reaction vessel body 1, a cover 2, and an ultrasonic radiation rod array 3; a hemispherical bottom 4 is provided at the lower part of the reaction vessel body 1, a base 5 is provided below the hemispherical bottom 4, and a discharge port 6 is provided on the hemispherical bottom 4; the cover 2 is connected to the top of the reaction vessel to seal the top of the reaction vessel, and at least one inlet 7 is provided on the cover, and a motor installation inlet 8 is provided at the center of the cover; the ultrasonic radiation rod array 3 includes a first mounting mechanism 9, and a plurality of first mounting holes are arrayed on the first mounting mechanism 9, and ultrasonic radiation rods 10 are installed in the first mounting holes. The ultrasonic radiation rods 10 are used to stir and mix the materials by ultrasonic vibration. The ultrasonic radiation rod array 3 also includes a first motor 11, which is connected to the first mounting mechanism 9 through the motor installation inlet 8. The first motor 11 is used to rotate the first mounting mechanism 9 to change the distribution position of each ultrasonic radiation rod 10.

[0022] It should be noted that in this embodiment of the invention, an ultrasonic radiant rod array 3 is used instead of a traditional stirring blade, avoiding the loss of some materials due to mechanical shearing force, thereby improving product quality. However, unlike traditional stirring, the ultrasonic radiant rod array 3 is generally fixed, resulting in varying distances from the ultrasonic radiant rods 10 and differences in mixing uniformity. Therefore, this invention also uses a first motor 11 to drive the ultrasonic radiant rod array 3, changing the distribution position of the ultrasonic radiant rods 10 during the reaction process to ensure uniform mixing in all areas.

[0023] In this specific embodiment, a jacket is provided on the outside of the reactor body 1, and a heater is provided in the jacket. The heater is used to heat the reactor body 1, and the jacket is used for heat preservation.

[0024] It should be noted that heating is required during the preparation process to ensure the smooth progress of the reaction. The jacket design can make the heating more uniform and prevent excessive heat loss, thereby saving energy.

[0025] In this specific embodiment, the feed inlet 7 is connected to a tangential jet nozzle array via a pipe. The tangential jet nozzle array is located at the bottom of the reactor body 1. The tangential jet nozzle array includes multiple tangential jet nozzles, which are used to add materials during the reaction process to form a tornado-like vortex.

[0026] It should be noted that this structure allows for more uniform mixing of different materials, especially functional additives added during the reaction, thus avoiding significant differences in reaction progress between different regions.

[0027] In this specific embodiment, a temperature sensor is also installed inside the reactor body 1. The temperature sensor is used to monitor the real-time temperature during the reaction process, and then control the heating temperature according to the real-time temperature.

[0028] It should be noted that temperature monitoring is a crucial part of the preparation process. Ensuring that the temperature meets the requirements can guarantee reaction efficiency and reduce the generation of byproducts.

[0029] In this specific embodiment, the reactor body 1 is also provided with a vacuum interface, which is connected to a vacuum pumping device. The vacuum pumping device is used to draw a vacuum before gelation to remove dissolved air and bubbles entrained by stirring.

[0030] In this specific embodiment, a near-infrared spectral sensor is also provided inside the main body 1 of the reaction vessel. The near-infrared spectral sensor is used to detect the uniformity of the concentration distribution of the bactericide.

[0031] In this specific embodiment, the inlet 7 includes a solid material inlet 7 for solid materials to enter and a liquid material inlet 7 for liquid materials to enter.

[0032] It should be noted that different forms of materials require different inlet structures 7 to ensure smooth material addition. For example, the inlet 7 for solid materials needs a dustproof structure to prevent material from flying away; while the inlet 7 for liquid materials needs a metering device to ensure the addition amount and speed.

[0033] This invention uses an ultrasonic radiation rod array 3 instead of traditional stirring blades to stir materials, achieving zero mechanical shear damage, avoiding loss of functional additives, and improving product quality.

[0034] The ultrasonic radiating rod array 3 of this invention is connected to a first motor 11. The first motor 11 is used to rotate the first mounting mechanism 9 to change the distribution position of each ultrasonic radiating rod 10, thereby avoiding the problem that the material mixing uniformity is worse in areas further away from the ultrasonic radiating rod 10 due to the fixed position of the ultrasonic radiating rod array 3.

[0035] In summary, this invention avoids the damage to additives caused by the mechanical shearing force generated by traditional stirring, and makes the materials more uniformly mixed, thus improving product quality.

[0036] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
