Description

Technical Field

[0001] This utility model relates to the field of carrageenan production technology, and to a mixing device for alcohol and carrageenan solution. Background Technology

[0002] The most common extraction method for carrageenan is to use hot or warm water for extraction, followed by filtration or centrifugation to remove impurities, resulting in an extract containing the target colloid. After purification and concentration, a large amount of water-miscible organic solvent (ethanol or isopropanol) is added to the extract, taking advantage of the characteristic that the solubility of polysaccharides in alcohol decreases sharply, causing them to precipitate.

[0003] Currently, common alcohol precipitation equipment mainly includes alcohol precipitation tanks. During precipitation, alcohol and carrageenan are first introduced in a certain ratio, and then the mixing system within the equipment mixes them evenly. Precipitation is completed within the equipment's volume. The precipitation effect can be adjusted according to the alcohol-to-carrageenan ratio and the time the mixture remains in the tank. However, existing carrageenan alcohol precipitation methods are simplistic, require large tank volumes and large amounts of alcohol, have low mixing efficiency, limited precipitation results, and the solid residue after precipitation easily clogs the pipes, leading to poor continuity.

[0007] In a further improvement, the adhesive rotor pump is a rotor pump with equal volume, and the first flow meter is an electromagnetic flow meter.

[0008] A further improvement is that the distance between the tee connector and the mixing pump inlet is less than 10cm, and the inner diameter of this section of the adhesive pipe is consistent with the inner diameter of the mixing pump inlet.

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.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] The following describes the embodiments and appendices. Figure 1 The technical solution of this utility model will be further described below.

[0016] Example 1 An apparatus for mixing alcohol and adhesive includes: an adhesive rotor pump 1, an adhesive pipeline 2, an alcohol pipeline 3, a first flow meter 4, a second flow meter 5, a first regulating valve 6, a second regulating valve 7, and a mixing pump 9. The adhesive rotor pump 1, the first regulating valve 6, and the first flow meter 4 are connected in series along the adhesive conveying direction on the adhesive pipeline, and the downstream end of the adhesive pipeline 2 is connected to the inlet of the mixing pump 9. The alcohol pipeline 3 is connected in series with the second regulating valve 7 and the second flow meter 5 along the alcohol delivery direction. The output end of the alcohol pipeline 3 is connected to the glue pipeline 2 through the tee connector 10, and the tee connector 10 is located between the first flow meter 4 and the mixing pump 9.

[0017] like Figure 1 As shown, in actual use, the present invention first starts the adhesive rotor pump 1, slowly opens the first regulating valve 6, and observes the real-time reading of the first flow meter 4: if the flow is insufficient, the frequency of the adhesive rotor pump 1 is increased; if the flow is too high, the first regulating valve 6 is closed until the adhesive flow stabilizes at the target value, and the adhesive is transported along the adhesive pipeline 2 to the three-way connector 10; secondly, after the adhesive flow stabilizes, the second regulating valve 7 is opened, and the alcohol enters the adhesive pipeline 2 through the three-way connector 10 after passing through the second flow meter 5 and the one-way valve 8; according to the actual adhesive flow of the first flow meter 4, the second regulating valve 7 is adjusted so that the alcohol flow displayed by the second flow meter 5 matches the preset ratio; finally, after the adhesive and alcohol initially merge at the three-way connector 10, they enter the mixing pump 9, and the mixing pump 9 is started, which achieves deep mixing and disperses the short fibers produced by alcohol precipitation through high-speed rotation.

[0018] During the use of this utility model, the frequency of the adhesive rotor pump 1 is adjusted, and the flow rate of the adhesive is controlled by the first regulating valve 6 in conjunction with the first flow meter 4. At the alcohol end, the ratio of the adhesive is matched by the second regulating valve 7 in conjunction with the second flow meter 5, which greatly improves the mixing uniformity and alcohol precipitation efficiency, allowing carrageenan to precipitate more fully and disperse better.

[0019] As a further preferred embodiment, a pressure gauge 91 is provided at the outlet of the mixing pump 9.

[0020] Specifically, by monitoring the material pressure at the outlet of the mixing pump 9 in real time, it is possible to quickly determine whether there are problems such as solid blockage or valve jamming inside the mixing pump 9 or in the downstream pipeline. This allows operators to stop the machine in time for troubleshooting, avoid overload damage to the mixing pump or pipeline leakage due to excessive pressure, ensure continuous and stable operation of the device, and reduce equipment maintenance costs.

[0021] As a further preferred embodiment, the adhesive rotor pump 1 is a rotor pump with equal volume, and the first flow meter 4 is an electromagnetic flow meter.

[0022] Specifically, the output flow rate of a rotary pump or other volumetric pump is in a fixed ratio to its rotation speed, and the amount of adhesive delivered can be precisely controlled by adjusting the frequency, resulting in small flow fluctuations. The electromagnetic flow meter is not affected by the viscosity or impurities of the adhesive and can accurately monitor the real-time flow rate of the adhesive, ensuring that the mixing ratio of each batch of adhesive and alcohol is consistent and improving the stability of the carrageenan alcohol precipitation effect.

[0023] As a further preferred embodiment, the distance between the tee connector 10 and the inlet of the mixing pump 9 is less than 10cm, and the inner diameter of the adhesive pipe 2 is consistent with the inner diameter of the inlet of the mixing pump 9.

[0024] Specifically, the conveying distance from the initial mixing of adhesive and alcohol at the tee joint 10 to the entry into the mixing pump 9 is shortened, reducing the residence time of materials in the pipeline and preventing the adhesive and alcohol from separating due to excessively long conveying paths, thus ensuring the stability of the materials after initial mixing. The inner diameter of the adhesive pipeline 2 is consistent with the inner diameter of the inlet of the mixing pump 9, which can eliminate the flow field disturbance caused by the change in pipeline diameter, prevent the material from forming eddies or accumulating at the change in diameter, ensure that the mixed materials enter the mixing pump 9 smoothly, and prevent solid impurities from accumulating in the change in diameter gap and causing blockage, further ensuring the continuous operation of the device.

[0025] As a further preferred embodiment, the second flow meter 5 is a turbine flow meter, and a one-way valve 8 is provided between the output end of the alcohol pipeline 3 and the adhesive pipeline 2.

[0026] Specifically, the turbine flow meter is adapted to the low viscosity and high fluidity characteristics of alcohol, and has high measurement accuracy; the one-way valve 8 can strictly prevent the material after the adhesive and alcohol are mixed from flowing back into the alcohol pipe 3, avoiding solid particles from clogging the alcohol pipe or contaminating the alcohol supply source, eliminating the need for frequent disassembly and cleaning of the alcohol pipe, and reducing the number of downtime maintenance; at the same time, it prevents the alcohol delivery from being interrupted due to backflow, ensuring a continuous and stable supply of alcohol and improving the continuity of the mixing process.

[0027] 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.
