Description

Technical Field

[0001] The utility model relates to the technical field of homogenization, in particular to a homogenization device, and specifically to a homogenization device for nanocellulose. Background Art

[0002] Homogenization, also known as slurrying, is the process of micronizing and homogenizing the dispersed matter in the suspension or emulsion system. Homogenization is a technology often used in the production of food or chemical industry. In the chemical industry, the main function of homogenization is to reduce the particles in the material to the micron or even nanometer level, so that the distribution of the components in the system is more uniform, reducing or eliminating the heterogeneity between phases, and achieving the purpose of improving reaction rate, improving product quality and reducing production costs. Nanocellulose is a fiber aggregate with a diameter of less than 100 nanometers and a length of up to microns. Nanocellulose has excellent mechanical properties, huge specific surface area, high crystallinity, good hydrophilicity, high transparency, low density, good biodegradability and biocompatibility, and stable chemical properties. In the existing technology, a single barrel circulating homogenizer is often used to process nanocellulose, which is a single A ton barrel containing nanocellulose is connected to a homogenizer in a ring shape. The ton barrel is used to store the initial slurry and the slurry after homogenization. The homogenizer performs homogenization processing. When working, the slurry in the ton barrel is passed to the homogenizer for homogenization. The homogenized material is returned to the ton barrel and circulated homogenized in this way. At this time, there will be materials before and after homogenization and different times of homogenization in the ton barrel. The slurry before homogenization and the slurry after homogenization are mixed in a single barrel. Under continuous circulation, the number of times the material is homogenized will be different. Some slurries have been homogenized many times, while some slurries have not even been homogenized, which makes the degree of homogenization of the material different, the homogenization effect is unstable, the degree of homogenization controllability is low, and in order to make the material with low homogenization degree meet the required standards, the homogenization time needs to be extended, which will greatly increase the time cost and energy loss of homogenization. Therefore, a homogenization device that can store different batches of homogenized slurry separately is needed. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a homogenizing device to solve the problems existing in the above-mentioned prior art. The present invention adopts a technical solution in which a homogenizer and multiple ton barrels are connected in sequence to form a circulation. The multiple ton barrels provided can store nanocellulose, so that nanocellulose from different homogenized batches can be stored independently, avoiding the problem of mixing nanocellulose from different homogenized batches.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] like Figure 1 As shown, the utility model provides a homogenizing device, including a first homogenizer 101, a first ton barrel 201 and a second ton barrel 202, the liquid inlet end of the first homogenizer 101 is connected to the liquid outlet end of the first ton barrel 201, the liquid outlet end of the first homogenizer 101 is connected to the liquid inlet end of the second ton barrel 202, and the liquid outlet end of the second ton barrel 202 is connected to the liquid inlet end of the first ton barrel 201, the first homogenizer 101, the first ton barrel 201 and the second ton barrel 202 form a circulation structure, when in use, the nanocellulose in the first ton barrel can be input into the first homogenizer 101 to complete a homogenization of the nanocellulose The nanocellulose enters the second ton barrel 202 for storage. When there is any nanocellulose left in the first ton barrel 201, unhomogenized and once homogenized nanocellulose can be obtained. If twice-homogenized nanocellulose is needed, the above process can be repeated again based on the once-homogenized nanocellulose. Similarly, the first ton barrel 201 and the second ton barrel 202 can always store nanocellulose of different homogenized batches, so that nanocellulose of different homogenized batches can be preserved independently, avoiding the problem of mixing of nanocellulose of different homogenized batches. If more batches of nanocellulose are to be obtained at the same time, the number of ton barrels can be increased.

[0030] like Figure 2 As shown, the present invention also includes a second homogenizer 102, the first homogenizer 101, the second homogenizer 102, the first ton barrel 201 and the second ton barrel 202 form a circulation structure, the liquid inlet end of the second homogenizer 102 is connected with the liquid outlet end of the second ton barrel 202, and the liquid outlet end of the second homogenizer 102 is connected with the liquid inlet end of the first ton barrel 201. The added second homogenizer 102 can work simultaneously with the first homogenizer 101, thereby improving the homogenization efficiency and shortening the homogenization time, and can simultaneously complete two batches of nanocellulose with different homogenization times. If more batches of nanocellulose are to be obtained at the same time, the number of ton barrels and homogenizers can be increased at the same time. In a preferred embodiment, the number of ton barrels is not less than the number of homogenizers.

[0031] like Figure 3 and Figure 4As shown, the present invention also includes a third ton barrel 203. The liquid inlet end of the third ton barrel 203 is connected to the liquid outlet end of the first homogenizer 101 or the liquid outlet end of the second homogenizer 102. The third ton barrel 203 does not participate in the circulation and can obtain nanocellulose with a specified number of homogenizations. For example, if it is necessary to retain a part of the nanocellulose homogenized once but the overall circulation processing number is five times, then part of the nanocellulose can be input into the third ton barrel 203 after one homogenization, and then the circulation processing can be carried out normally. If it is necessary to retain more nanocellulose that cannot be obtained by relying on the circulation processing, more independent ton barrels can be connected to the liquid outlet position of the homogenizer.

[0032] like Figures 1 to 4 As shown, the first ton barrel 201 is a feed barrel, and the second ton barrel 202 is a storage barrel. The feed barrel is connected to the raw material supply pipe, and the storage barrel is connected to the finished product discharge pipe. The feed barrel can serve as the feed end of the entire circulation structure, and the storage barrel can serve as the discharge end of the entire circulation structure.

[0033] The liquid inlet end of the homogenizer or the liquid outlet end of the tonnage barrel is equipped with a flow meter for counting the flow of the homogenized nanocellulose. In a preferred embodiment, the feed end of the first homogenizer 101 and / or the second homogenizer 102 is provided with a flow meter.

[0034] A particle size detection device is provided in the first homogenizer 101 and / or the second homogenizer 102. In a preferred embodiment, the particle size detection device is a laser particle size analyzer. During homogenization, the pressure range of the homogenizer is 48-56 MPa, and the particle size meets the D50≤1 μm requirement.

[0035] The first ton barrel 201 and the second ton barrel 202 are provided with a stirrer and a temperature control device for uniform slurry. The stirrer adjusts the uniformity of the slurry in the ton barrel to avoid sedimentation. The temperature control device can maintain the temperature in the ton barrel at the optimal temperature for preserving nanocellulose and prevent the nanocellulose from deteriorating.

[0036] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
