Description

Technical Field

[0001] This application relates to the field of chemical solution treatment technology, and in particular to an apparatus for reducing the viscosity of slurry solutions and a method for using the same. Background Technology

[0002] Slurries have wide applications in many industrial fields, such as pharmaceuticals, chemicals, and food processing. However, slurries often face the problem of excessive viscosity during use. Excessive viscosity can lead to uneven mixing, difficulty in spraying, poor flowability, and even defects in the final product. This not only affects the smooth progress of processes such as spraying but may also damage related equipment. These problems often need to be solved by reducing the viscosity of the slurry.

[0003] The viscosity of a slurry is determined by many factors, including the properties of the active material itself, the slurry temperature, the proportions of the materials used, the amount of dispersant, and the ratio of solids. These factors can all directly affect the viscosity of the slurry. Even when the temperature and proportions are fixed, the viscosity can still be high. High viscosity has an adverse effect on the dispersion effect. Existing solutions often involve adding diluents or adjusting the amount of dispersant, or using high-energy mixing equipment to achieve the optimal viscosity. However, these methods are often time-consuming, energy-intensive, or increase the amount of chemicals used, leading to higher costs. They may also affect the composition of the slurry. Therefore, there is an urgent need to develop a new type of equipment to reduce the viscosity of the slurry more effectively and conveniently. Summary of the Invention

[0004] This application provides an apparatus and method for reducing the viscosity of a slurry solution, which solves the problem that commonly used apparatuses or methods for reducing slurry viscosity in the prior art are often time-consuming and energy-intensive, making it difficult to reduce the viscosity of slurry efficiently and conveniently.

[0005] This application provides an apparatus for reducing the viscosity of a slurry solution, comprising:

[0006] Bottom support platform;

[0007] A closed mixing tank is located above the bottom support platform and is used to contain the added slurry. It is also provided with a feed port for adding slurry.

[0008] The sealed mixing tank is also equipped with a stirring detection group for reducing the viscosity of the slurry. The stirring detection group can periodically detect the viscosity of the slurry added into the sealed mixing tank to determine whether it has reached the expected viscosity.

[0009] Preferably, the enclosed mixing tank comprises:

[0010] The bottom tank is fixedly connected to the upper surface of the bottom support platform. The inlet is located at the top of the bottom tank, and the outlet is located on one side of the bottom of the bottom tank.

[0011] A closed end cap, located above the bottom tank, can seal the bottom tank.

[0012] Preferably, the stirring detection group includes:

[0013] A stirring assembly is used to stir the slurry added into the closed mixing tank to reduce its viscosity;

[0014] The detection component is connected to the stirring component to detect and determine whether the slurry being stirred has reached the expected viscosity.

[0015] Preferably, the stirring assembly includes a drive motor, a stirring shaft, and stirring blades;

[0016] The drive motor is located inside the closed end cover, and the output end of the drive motor passes through the lower surface of the closed end cover and is fixedly connected to one end of the stirring shaft.

[0017] The stirring blades are provided in a plurality of manner, and the plurality of stirring blades are arranged in a ring array at the end of the stirring shaft away from the drive motor.

[0018] Preferably, the stirring assembly further includes:

[0019] A heating assembly, located at the bottom of the closed mixing tank, includes multiple sets of heating wires for heating the slurry added into the closed mixing tank;

[0020] An ultrasonic generator includes multiple piezoelectric transducers arranged in a circumferential array along the inner wall of the enclosed mixing tank.

[0021] Preferably, the detection component includes:

[0022] A viscosity rotor is disposed inside the stirring assembly, and the viscosity rotor is connected to the drive motor via the stirring shaft;

[0023] A viscosity sensor, coupled to the viscosity rotor, is used to detect the viscosity of the slurry during stirring;

[0024] A flow meter is installed on one side of the outlet to detect the actual flow rate of the slurry flowing out of the outlet.

[0025] Preferably, the stirring and detection group further includes a central control system for controlling its overall operation. The central control system is located inside the bottom support platform and is connected to the detection component and the stirring component respectively.

[0026] The central control system is also equipped with a preset judgment threshold. The central control system can judge the detection data of the detection component according to the preset judgment threshold to determine whether the slurry in the closed mixing tank has reached the expected viscosity.

[0027] This application also provides a method of using the apparatus for reducing the viscosity of a slurry solution based on any of the above claims, comprising:

[0028] Step S1: Add the slurry to be processed into the inside of the closed mixing tank through the feed port;

[0029] Step S2: Start the mixing unit to mix the added slurry;

[0030] Step S3: Activate the detection component to periodically detect the slurry during mixing;

[0031] Step S4: The central control system judges the detected data to determine whether the slurry being processed has reached the expected viscosity. If it has, the processed slurry is discharged through the outlet.

[0032] Step S5: The actual flow rate of the slurry during discharge is detected by a flow meter, and the central control system determines whether the actual flow rate meets the expected flow rate standard. If it does, the slurry continues to be discharged.

[0033] Preferably, the central control system is equipped with a preset judgment threshold, which includes a expected viscosity judgment value and an expected flow rate judgment value;

[0034] The detection component can periodically detect the actual viscosity of the slurry during stirring using a viscosity sensor connected to the viscosity rotor.

[0035] The central control system can determine the actual viscosity detected by the detection component based on the expected viscosity determination value;

[0036] In step S4, the process by which the central control system determines the actual viscosity based on the expected viscosity determination value is as follows:

[0037] If the actual viscosity is less than or equal to the expected viscosity determination value, it is determined that the slurry being processed has reached the expected viscosity, and the processed slurry is discharged through the discharge port.

[0038] If the actual viscosity is greater than the expected viscosity value, it is determined that the slurry being processed has not reached the expected viscosity, and it will be stirred further by the stirring assembly.

[0039] Preferably, the central control system can determine the actual flow rate detected by the flow meter based on the expected flow rate determination value;

[0040] In step S5, the process by which the central control system determines the actual flow rate based on the expected flow rate determination value is as follows:

[0041] If the actual flow rate is greater than or equal to the expected flow rate value, it is determined that the actual flow rate of the discharged slurry has reached the expected flow rate standard, and the processed slurry continues to be discharged through the discharge port.

[0042] If the actual flow rate is less than the expected flow rate value, it is determined that the actual flow rate of the discharged slurry has not reached the expected flow rate standard. The discharge port will be closed to stop the discharge, and the slurry will be stirred again by the stirring component. This discharge will be recorded.

[0043] The beneficial effects of this application are as follows:

[0044] The device for reducing the viscosity of slurry solution disclosed in this application uses a stirring component in a stirring detection group to stir the slurry. The driving motor in the stirring component drives the stirring blades to stir the added slurry. At the same time, an ultrasonic generator and a heating component work together with the stirring blades to accelerate the process of reducing the viscosity of the slurry. This device can significantly reduce the viscosity of the slurry solution in a short time to improve its production efficiency. Furthermore, by adopting a physical treatment method, there is no need to add additional chemical substances, which avoids interference from additional components with the slurry composition, reduces the use and maintenance costs of chemical additives, improves the durability and service life of the equipment, and thus reduces the overall cost of the production process.

[0045] Furthermore, by periodically detecting the slurry in the processing through the detection components in the stirring detection group, the slurry that has reached the expected viscosity can be detected in a timely manner, thereby reducing unnecessary stirring operations and improving the overall production efficiency while reducing production costs.

[0046] In particular, by cooperating with the set detection components and the central control system, the slurry during and after processing is dually detected to ensure the viscosity of the discharged slurry. This ensures that the slurry after processing can still maintain the viscosity range required for subsequent use when it flows through the outlet after the mixing is finished, thus guaranteeing its normal participation in subsequent use.

[0055] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] The following is combined Figures 1-5 This application describes the apparatus for reducing the viscosity of slurry solutions and its usage method provided in the embodiments of this application.

[0057] Reference Figure 1 As shown, the device for reducing the viscosity of a slurry solution provided in this application embodiment includes a bottom support platform 100;

[0058] A closed mixing tank 200 is set above the bottom support platform 100 to hold the added slurry, and it is also provided with a feed port for adding slurry.

[0059] The sealed mixing tank 200 is also equipped with a mixing and detection group 300 for reducing the viscosity of the slurry. The mixing and detection group 300 can periodically detect the viscosity of the slurry added into the sealed mixing tank 200 to determine whether it has reached the expected viscosity. The detection cycle interval should be adaptively selected based on the actual operating power of the mixing components and the initial viscosity of the slurry to be treated. In order to avoid wasting detection resources by multiple tests, the detection cycle interval should not be too short. However, in order to avoid the detection cycle interval being too long, which would cause the mixing components to operate excessively and thus waste power resources, the detection cycle should not be set too long. Therefore, considering all factors, the interval between each cycle should not be less than 1 minute and not more than 5 minutes. The initial detection interval can be adaptively extended according to the initial viscosity of the added slurry to be treated.

[0060] The slurry is stirred by the stirring component in the stirring and detection group 300. The drive motor in the stirring component drives the stirring blade 320 to stir the added slurry. At the same time, the ultrasonic generator and heating component work together with the stirring blade 320 to accelerate the process of reducing the viscosity of the slurry. This allows the device to significantly reduce the viscosity of the slurry solution in a short time to improve its production efficiency. At the same time, by adopting a physical treatment method, there is no need to add additional chemical substances, which avoids the interference of additional components on the slurry composition, reduces the use and maintenance costs of chemical additives, improves the durability and service life of the equipment, and thus reduces the overall cost of the production process.

[0061] By cooperating with the set detection components and the central control system 330, the slurry during and after processing is dually detected to ensure the viscosity of the discharged slurry. This ensures that the slurry after processing can still maintain the viscosity range required for subsequent use when it flows through the outlet after the mixing is finished, thus guaranteeing its normal participation in subsequent use.

[0062] Please continue reading. Figure 2 and Figure 3 ,like Figure 2 and Figure 3 As shown, where, Figure 2 This is a schematic diagram of the overall structure of the support base in an embodiment of this application. Figure 3 This is a schematic diagram of the overall structure of the closed end cap 220 in the embodiments of this application;

[0063] In some specific embodiments, the enclosed mixing tank 200 includes:

[0064] The bottom tank 210 is fixedly connected to the upper surface of the bottom support platform 100. The inlet is located at the top of the bottom tank 210, and the outlet is also located on one side of the bottom of the bottom tank 210.

[0065] The closed end cap 220 is located above the bottom tank 210 and can seal the bottom tank 210.

[0066] The overall diameter of the closed end cap 220 is larger than the opening diameter of the feed inlet. The bottom of the closed end cap 220 is provided with an annular groove. The bottom of the closed end cap 220 forms a contraction section with a bottom diameter smaller than the top diameter through the annular groove. The closed end cap 220 can be inserted into the bottom tank 210 through the contraction section. The diameter of the contraction section is slightly larger than the opening diameter of the feed inlet, so that it forms an interference fit with the feed inlet and increases its sealing effect on the tank space.

[0067] Furthermore, a sealing ring can be added between the closed end cap 220 and the feed inlet to enhance its sealing performance.

[0068] In another embodiment of this application, the lower surface of the closed end cap 220 is fixedly connected to the upper surface of the bottom tank 210, and the feed inlet is opened on the outer surface of the bottom tank 210 near the closed end cap 220, so that the closed end cap 220 does not need to be opened for each feeding, thereby further improving its sealing performance.

[0069] In some specific embodiments, the stirring detection group 300 includes:

[0070] A stirring assembly is used to stir the slurry added into the closed mixing tank 200 to reduce its viscosity;

[0071] The detection component is connected to the mixing component to detect and determine whether the slurry being mixed has reached the expected viscosity.

[0072] In some specific embodiments, the stirring assembly includes a drive motor, a stirring shaft 310, and stirring blades 320;

[0073] The drive motor is located inside the closed end cover 220. The output end of the drive motor passes through the lower surface of the closed end cover 220 and is fixedly connected to one end of the stirring shaft 310. The closed end cover 220 also has a mounting cavity for installing the drive motor, and the drive motor is a variable frequency motor with adjustable speed.

[0074] Multiple stirring blades 320 are provided, and the multiple stirring blades 320 are arranged in a ring array at the end of the stirring shaft 310 away from the drive motor.

[0075] Specifically, the stirring shaft 310 is driven by a drive motor to rotate, which in turn drives the stirring blades 320 to rotate in the slurry to stir the slurry added into the closed mixing tank 200, so as to reduce the viscosity of the slurry and maintain its fluidity.

[0076] In some specific embodiments, the stirring assembly further includes:

[0077] The heating component, located at the bottom of the closed mixing tank 200, includes multiple sets of heating wires to heat the slurry added into the closed mixing tank 200. This works in conjunction with the stirring blades 320 to reduce the difficulty of stirring the added slurry, improve the stirring effect, and reduce the viscosity of the slurry during stirring. Generally, to ensure that the heating component can adapt to the heating temperature required by various slurries, the selected heating component can be selected with a heating range of 20℃-80℃. This expands the selectable heating range while meeting the required activity of the slurry to be treated. The stirring group is also equipped with a temperature control unit 340 to work with the heating component to heat the slurry to be treated, keeping it within a certain range, thereby ensuring the stability of the stirring and testing group 300 during operation.

[0078] The ultrasonic generator includes multiple piezoelectric transducers arranged in a circumferential array along the inner wall of the closed mixing tank 200. In the specific implementation process, the circumferentially arranged ultrasonic generator generates a cavitation effect through high-frequency vibration, which, together with the stirring blades 320, breaks down the slurry added into the closed mixing tank 200, thereby destroying the intermolecular forces in the slurry, reducing its overall viscosity, and improving the overall stirring effect of the stirring assembly.

[0079] In some specific embodiments, the detection component includes:

[0080] The viscosity rotor is located inside the stirring assembly and is connected to the drive motor via the stirring shaft;

[0081] A viscosity sensor, coupled to a viscosity rotor, is used to detect the viscosity of the slurry during stirring.

[0082] A flow meter, located on one side of the outlet, is used to detect the actual flow rate of the slurry flowing out of the outlet.

[0083] The viscosity sensor should be selected adaptively according to the actual type of the selected viscosity rotor. There are various types, such as rotary (torque / speed detection), vibration (damping effect detection), and differential pressure (fluid pressure drop detection). In this embodiment, the selected viscosity rotor is a rotary single-cylinder rotor. Therefore, the required viscosity sensor should be a rotary sensor that matches the type of rotary rotor. Similarly, if other types of viscosity rotors are used, appropriate matching should also be performed.

[0084] Specifically, the viscosity of the slurry is measured and characterized by the operating power of the viscosity rotor through the stirring shaft 310 or stirring blade 320 in the slurry, so as to visualize the viscosity and facilitate subsequent comparison and judgment. The actual flow rate of the slurry at the outlet is measured and characterized by the flow meter, and the actual viscosity of the treated slurry is visualized to determine whether the treated slurry meets the expected standards. This prevents slurry that does not meet the expected standards from flowing into subsequent use steps, thereby improving the quality of the final product.

[0085] In some specific embodiments, the stirring and detection assembly 300 also includes a central control system 330 for controlling the operation of the assembly. The central control system 330 is located inside the bottom support platform 100 and is connected to the detection assembly and the stirring assembly respectively.

[0086] The central control system 330 is also equipped with a preset judgment threshold. The central control system 330 can judge the detection data of the detection component according to the preset judgment threshold to determine whether the slurry in the closed mixing tank 200 has reached the expected viscosity.

[0087] The preset judgment thresholds are the expected viscosity judgment value and the expected flow rate judgment value, and both should be adapted and set according to the viscosity required by the slurry to be processed in subsequent use;

[0088] The working process is as follows: Select the slurry to be treated and add it into the sealed mixing tank 200 through the feed inlet. Start the drive motor to drive the stirring blades 320 to stir the added slurry. Simultaneously, activate the ultrasonic generator and heating assembly to assist the stirring assembly in reducing the viscosity of the slurry. This allows the instrument to significantly reduce the viscosity of the slurry solution in a short time, thereby improving production efficiency. Furthermore, by employing a physical treatment method, no additional chemical substances are needed, avoiding interference from extra components with the slurry composition. This reduces the use and maintenance costs of chemical additives, improves the durability and lifespan of the equipment, and ultimately lowers overall production costs. Activate the detection assembly; the viscosity sensor in the detection assembly, in conjunction with the viscosity rotor, monitors the viscosity of the slurry during processing. The actual viscosity of the slurry is periodically tested, and the central control system 330 judges each detected actual viscosity to determine whether it has reached the expected viscosity. When the detected actual viscosity is determined to have reached the expected viscosity, stirring is stopped, the outlet is opened to discharge the treated slurry, and the flow rate of the slurry flowing through the outlet is detected by the flow sensor in the detection component. The central control system 330 judges the detected actual flow rate to determine whether it has reached the expected flow rate standard. When it is determined that the expected flow rate standard has been reached, the treatment is completed, and the treated slurry is completely discharged. If it is determined that the expected flow rate standard has not been reached, the outlet is closed, the stirring component is started, and the above operation is repeated until the judgment is passed.

[0089] Please continue reading. Figure 4 ,like Figure 4 The diagram shown is a flowchart of the method of using the apparatus for reducing the viscosity of a slurry solution provided in this application embodiment;

[0090] Specifically, this application also provides a method of using the apparatus for reducing the viscosity of a slurry solution based on any of the above claims, comprising:

[0091] Step S1: Add the slurry to be processed into the interior of the closed mixing tank 200 through the feed port;

[0092] Step S2: Start the mixing unit to mix the added slurry;

[0093] Step S3: Activate the detection component to periodically detect the slurry during mixing;

[0094] Step S4: The central control system 330 judges the detected data to determine whether the slurry being processed has reached the expected viscosity. If it has, the processed slurry is discharged through the outlet.

[0095] Step S5: The actual flow rate of the slurry during discharge is detected by a flow meter, and the detected actual flow rate is judged by the central control system 330 to determine whether the actual flow rate meets the expected flow rate standard. If it does, the slurry continues to be discharged.

[0096] Please continue reading. Figure 5 ,like Figure 5 As shown, it is a logic diagram for determining whether the processed slurry should continue to be discharged in an embodiment of this application;

[0097] In some specific embodiments, the central control system 330 is provided with a preset judgment threshold, which includes a expected viscosity judgment value and an expected flow rate judgment value.

[0098] The detection component can periodically detect the actual viscosity of the slurry during stirring using a viscosity sensor connected to the viscosity rotor;

[0099] The central control system 330 can determine the actual viscosity detected by the detection component based on the expected viscosity judgment value;

[0100] In step S4, the process by which the central control system 330 determines the actual viscosity based on the expected viscosity value is as follows:

[0101] If the actual viscosity is less than or equal to the expected viscosity, the slurry being processed is determined to have reached the expected viscosity, and the processed slurry is discharged through the outlet.

[0102] If the actual viscosity is greater than the expected viscosity value, it is determined that the slurry in the process has not reached the expected viscosity, and it will be stirred by the stirring component.

[0103] In some specific embodiments, the central control system 330 can determine the actual flow detected by the flow meter based on the expected flow determination value;

[0104] In step S5, the process by which the central control system 330 determines the actual flow rate based on the expected flow rate is as follows:

[0105] If the actual flow rate is greater than or equal to the expected flow rate, it is determined that the actual flow rate of the discharged slurry has reached the expected flow rate standard, and the treated slurry continues to be discharged through the outlet.

[0106] If the actual flow rate is less than the expected flow rate, it is determined that the actual flow rate of the discharged slurry has not reached the expected flow rate standard. The discharge port will be closed to stop the discharge, and the slurry will be stirred again by the stirring component. This discharge will be recorded.

[0107] In the specific implementation process, the expected viscosity and expected flow rate should be selected according to the viscosity required for the slurry to be treated in subsequent use. For example, if the initial viscosity of the slurry to be treated when it is added to the closed mixing tank 200 is 10 Pa·s, and the expected viscosity for subsequent use is 2 Pa·s, then 2 Pa·s can be selected as its expected viscosity. The expected flow rate should be selected in combination with the determined expected viscosity and the diameter of the outlet. Where Q = Vp * A, Vp is the average flow rate, A is the cross-sectional area of ​​the outlet, Vp = ΔP·R2 / 8ηL, η is the viscosity, ΔP is the static pressure of the slurry in the container, and R is the opening radius of the outlet.

[0108] Assuming the final result is that the flow rate of the slurry discharged from the outlet should be 10 L / min during the period when the viscosity is within the required range, some specific embodiments are as follows:

[0109] The slurry to be processed is added into the interior of the closed mixing tank 200 through the feed port. At this time, the initial viscosity of the slurry is 10 Pa·s.

[0110] Start the stirring assembly, drive the stirring shaft 310 and stirring blade 320 to rotate via the drive motor, set the stirring speed to 300 r / min, and simultaneously start the ultrasonic generator and heating device, set the ultrasonic generator frequency to 40 kHz and the power to 300 W, and heat the slurry to 40°C or above via the heating device, and maintain the temperature stable via the temperature control unit 340, keeping it within a certain temperature range.

[0111] The detection component is activated to periodically detect the actual viscosity of the slurry during the processing using a viscosity sensor;

[0112] The central control system 330 determines the actual viscosity detected by the detection component based on the expected viscosity judgment value. If the actual viscosity is less than or equal to 2 Pa·s, it is determined that the slurry being processed has reached the expected viscosity. That is, at this time, the slurry in the closed mixing tank 200 has reached the viscosity range required for subsequent use after being crushed and stirred by the mixing component. At this time, the processed slurry can be discharged through the discharge port.

[0113] If the actual viscosity is greater than 2 Pa·s, it is determined that the slurry being processed has not reached the expected viscosity. That is, the slurry in the closed mixing tank 200 has not yet reached the viscosity range required for subsequent use. Therefore, it is necessary to continue to stir and break it up by the stirring components and wait for the next detection.

[0114] The central control system 330 determines the actual flow rate detected by the flow meter based on the expected flow rate judgment value. If the actual flow rate is greater than or equal to 10L / min, it is determined that the actual flow rate of the discharged slurry has reached the expected flow rate standard. That is, the slurry after the mixing is finished and it flows through the outlet can still maintain the viscosity range required for subsequent use, which means that it can be used normally in subsequent use. Therefore, it can continue to be discharged through the outlet for subsequent use.

[0115] If the actual flow rate is less than 10 L / min, it is determined that the actual flow rate of the discharged slurry has not reached the expected flow rate standard. That is, the actual flow rate of the treated slurry after the stirring ends and it flows through the outlet cannot be maintained within the viscosity range required for subsequent use. This means that the slurry discharged through the outlet cannot be used normally for subsequent use. Therefore, the outlet must be closed to stop the discharge, and the slurry must be stirred again by the stirring component until it can reach the expected flow rate standard before being discharged.

[0116] Furthermore, the central control system 330 is also equipped with a preset recording threshold. If the number of consecutive records reaches the preset recording threshold, an alarm will be triggered to remind external personnel to carry out timely maintenance to check whether there is any damage in the mixing and detection group 300, which may lead to errors in the flow meter or viscosity sensor. Alternatively, the operating power of the mixing components may be appropriately increased to enhance the mixing effect, so that the slurry discharged can also achieve the expected viscosity and ensure the treatment effect.
