Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of plastics technology, specifically a powder activation and dispersion device. Background Technology
[0002] In the field of plastics technology, powder materials are widely used. For example, calcium carbonate, glass fiber, and flame-retardant masterbatches are often used as functional fillers to improve the performance of plastic products. However, untreated powders present numerous problems in plastic matrices. Taking calcium carbonate as an example, its surface has a large number of hydroxyl groups, making it hydrophilic and oleophobic. This makes it difficult to disperse evenly in silane-based rubbers, plastics, and other high-molecular-weight organic compounds, hindering the formation of good chemical cross-linking and interfacial adhesion with the matrix, thus severely affecting the overall performance of plastic products. Traditional powder activation and dispersion methods typically involve preheating liquid raw materials such as dispersants and coupling agents that require preheating using separate equipment before conveying the preheated liquid to a spraying device. The spraying device then adds the powder by spraying it from above. This method of heating before conveying and spraying not only makes it difficult to ensure the temperature stability of the liquid raw materials during the conveying and spraying process, but also easily affects the subsequent powder activation effect due to the unidirectional contact direction between the liquid and the powder and insufficient mixing. Utility Model Content
[0003] This utility model provides a solution that addresses the problem of overly simplistic solutions in existing technologies. It offers a significantly different approach by providing a powder activation and dispersion device. This device addresses the technical problem mentioned in the background section of traditional powder activation and dispersion, where liquid raw materials such as dispersants and coupling agents that require preheating must be preheated by a separate device before being transported to a spraying device and then sprayed from above the powder. This makes it difficult to ensure the temperature stability of the liquid during transport and spraying, thus affecting the powder activation and dispersion effect.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A powder activation and dispersion device includes a housing assembly, a cover assembly on the top of the housing assembly, and a dispersion assembly and a storage assembly disposed on the cover assembly.
[0005] The housing assembly includes a powder processing chamber, and a first valve is installed at the bottom center of the powder processing chamber.
[0006] The cover assembly includes a cover, the top of which is fitted with an annular tube.
[0007] The dispersing assembly includes a rotating rod rotatably connected to the center of the lid. Multiple stirring discs are evenly and equidistantly distributed on the outer wall of the rotating rod, and a driving mechanism for driving its rotation is provided at the top of the rotating rod.
[0008] More preferably, the outer wall of the powder processing chamber is provided with a first mounting ring and a support ring from top to bottom, and the bottom of the support ring has a plurality of first legs distributed in a ring shape.
[0009] More preferably, the bottom of the cover is provided with a second mounting ring, and the outer walls of both the first and second mounting rings are provided with circular holes distributed in an annular pattern, and the first and second mounting rings are fastened together by bolts.
[0010] More preferably, a mounting bracket is installed on the top of the cover, a drive motor is installed on the top of the mounting bracket, the output end of the drive motor is connected to the rotating rod, and a scraper is installed on the outer wall of the rotating rod.
[0011] More preferably, the storage assembly includes a storage tank and a centrifugal pump. The bottom of the storage tank is provided with a second leg arranged in a ring. The second leg and the centrifugal pump are both installed on the top of the cover. The bottom of the storage tank is connected to the centrifugal pump through a second valve. A third valve is installed on the top of the storage tank. The outer wall of the storage tank is provided with a cavity, and a spiral heating wire is provided in the cavity. A temperature sensor is provided inside the storage tank.
[0012] More preferably, the storage components are provided in multiple ways, the top of the annular tube is provided with multiple liquid inlet pipes, and each liquid inlet pipe is connected to the centrifugal pump of the corresponding storage component, and the annular tube is provided with nozzles distributed in a ring.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This powder activation and dispersion device, through a storage component, uses a storage tank with a temperature sensor and a spiral heating wire to monitor and regulate the temperature of liquid raw materials such as dispersants and coupling agents in real time. This prevents changes in the viscosity of the raw materials or a decrease in the activity of the components due to temperature fluctuations, ensuring that the liquid raw materials are always in a stable state required by the process. Furthermore, the second valve is an electric flow control valve that monitors and regulates the liquid flow rate. The liquid raw materials can be transported to the annular pipe by a centrifugal pump, and then formed into fine droplets through the bottom annularly distributed atomizing nozzles. This uniformly sprays the dispersant / coupling agent into the powder processing chamber, allowing the droplet-shaped liquid raw materials to fully contact the powder being stirred, improving the liquid-powder mixing efficiency and ensuring the consistency and stability of the powder activation effect.

On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0019] Please refer to the appendix carefully. Figures 1-6 A powder activation and dispersion device includes a housing assembly 1, a cover assembly 2 is provided on the top of the housing assembly 1, and a dispersion assembly 3 and a storage assembly 4 are provided on the cover assembly 2.
[0020] The housing assembly 1 includes a powder processing chamber 101, and a first valve 105 is installed at the bottom center of the powder processing chamber 101.
[0021] The cover assembly 2 includes a cover 201, and an annular tube 203 is installed on the top of the inner wall of the cover 201.
[0022] The dispersing component 3 includes a rotating rod 303 rotatably connected to the center of the cover 201. Multiple stirring discs 305 are evenly and equidistantly distributed on the outer wall of the rotating rod 303. A driving mechanism for driving the rotation of the rotating rod 303 is provided on the top of the rotating rod 303.
[0023] In this embodiment, as Figure 2 As shown, the outer wall of the powder processing chamber 101 is provided with a first mounting ring 102 and a support ring 103 from top to bottom, and the bottom of the support ring 103 has a number of first legs 104 distributed in a ring shape.
[0024] Through the above structure, the multiple first legs 104 can provide uniform support force for the powder processing chamber 101, disperse the weight of the powder processing chamber 101 and the internal material, prevent the powder processing chamber 101 from tilting due to uneven force, and improve the stability of the overall structure during the dispersion operation.
[0025] In this embodiment, as Figure 2 and Figure 3 As shown, the bottom of the cover 201 is provided with a second mounting ring 202. The outer walls of the first mounting ring 102 and the second mounting ring 202 are provided with circular holes distributed in an annular pattern, and the first mounting ring 102 and the second mounting ring 202 are fastened together by bolts.
[0026] With the above structure, the annularly distributed circular holes can be aligned with bolts to install the first mounting ring 102 and the second mounting ring 202, which facilitates the subsequent disassembly of the cover 201 and provides convenience for subsequent maintenance and cleaning of the powder processing chamber 101.
[0027] In this embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, a mounting bracket 301 is installed on the top of the cover 201, and a drive motor 302 is installed on the top of the mounting bracket 301. The output end of the drive motor 302 is connected to the rotating rod 303 for transmission. A scraper 304 is installed on the outer wall of the rotating rod 303. The drive motor 302 can be a servo motor or a frequency converter motor.
[0028] With the above structure, when the drive motor 302 is started, the rotating rod 303 can drive the scraper 304 and multiple mixing discs 305 to rotate. The multiple mixing discs 305 disperse the material in the powder processing chamber 101, and the scraper 304 can scrape off the material attached to the inner wall of the powder processing chamber 101 to avoid the accumulation of material residue and affect the dispersion effect.
[0029] In this embodiment, as Figure 6As shown, the storage assembly 4 includes a storage tank 401 and a centrifugal pump 402. The bottom of the storage tank 401 is provided with a second support leg 403 arranged in a ring. The second support leg 403 and the centrifugal pump 402 are both installed on the top of the cover 201. The bottom of the storage tank 401 is connected to the centrifugal pump 402 through a second valve 404. A third valve 405 is installed on the top of the storage tank 401. The outer wall of the storage tank 401 has a cavity inside, and a spiral heating wire is provided in the cavity. A temperature sensor is also provided inside the storage tank 401.
[0030] Through the above structure, the temperature sensor can monitor the material temperature in the storage tank 401 in real time and feed back the data to the PLC control host. When the temperature is detected to be lower than the set threshold, the spiral heating wire is automatically powered on and works. By heating the outer wall of the storage tank 401, heat is evenly transferred to the internal material, ensuring that the material is always maintained within the temperature range required by the process. By regulating the temperature stability of liquid raw materials such as dispersants and coupling agents, viscosity changes or decreases in component activity caused by temperature fluctuations are avoided, providing a constant temperature and stable raw material supply for the subsequent powder activation and dispersion process, thereby ensuring the reliability of the production process.
[0031] In this embodiment, as Figure 3 , Figure 4 and Figure 6 As shown, there are multiple storage components 4. The top of the annular pipe 203 is provided with multiple liquid inlet pipes 204, and each liquid inlet pipe 204 is connected to the centrifugal pump 402 of the corresponding storage component 4. The annular pipe 203 is provided with nozzles distributed in a ring. The second valve 404 is an electric flow control valve used to monitor and adjust the liquid flow.
[0032] With the above structure, when the centrifugal pump 402 is started, the dispersant or coupling agent in the storage tank 401 enters the pump body through the second valve 404, and is transported to the annular pipe 203 through the liquid inlet pipe 204. Then, the liquid forms fine droplets through the atomizing nozzles distributed in an annular pattern at the bottom, and is evenly sprayed onto the powder processing chamber 101 below, so as to achieve efficient contact between the dispersant or coupling agent and the powder.
[0033] It should be noted that in this utility model, the temperature sensor, spiral heating wire, centrifugal pump 402 and each valve are all electrically connected to the PLC or single-chip microcomputer control system. The system receives the temperature signal and controls the power of the spiral heating wire through the PID algorithm to maintain the liquid temperature in the storage tank 401 at the set value. At the same time, it controls the start and stop of each centrifugal pump 402 and the opening degree of each valve to control the flow rate and sequence of each liquid raw material.
[0034] The specific operating procedure of this utility is as follows: First, the overall structure is sealed and stable by detachably connecting the cover 201 to the powder processing chamber 101. Then, an appropriate amount of powder is added to the powder processing chamber 101 through the valve on the cover 201. Next, a dispersant or coupling agent is added to the storage tank 401 through the third valve 405 of the corresponding storage component 4.
[0035] Next, the drive motor 302 on the mounting frame 301 is started to drive the rotating rod 303 to rotate, which drives the multiple stirring discs 305 on the outer wall to shear and disperse the powder. At the same time, the scraper 304 rotates synchronously to scrape off the material attached to the inner wall of the powder processing chamber 101 in real time, so as to avoid the accumulation of residues that affect the dispersion effect.
[0036] Meanwhile, the temperature of the dispersant or coupling agent in the storage tank 401 is monitored in real time by a temperature sensor. When the temperature is lower than the set threshold, the spiral heating wire automatically heats up and conducts heat through the cavity on the outer wall of the tank to ensure that the liquid raw material is maintained within the temperature range required by the process.
[0037] Subsequently, the second valve 404 corresponding to the storage component 4 is opened, and the centrifugal pump 402 delivers the constant temperature liquid through the liquid inlet pipe 204 to the annular pipe 203 at the top of the inner wall of the cover 201. The liquid is then sprayed evenly into the powder processing chamber 101 through the atomizing nozzles distributed in an annular pattern at the bottom, where it is fully mixed with the powder being stirred.
[0038] Multiple storage components 4 can independently control the supply of different liquid raw materials. The electric flow valve regulates the amount of each raw material added, realizing the synergistic supply of multiple components such as dispersants and coupling agents. After processing, the powder is discharged through the first valve 105 at the bottom of the powder processing chamber 101, completing the entire activation and dispersion process.
[0039] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
