Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic product manufacturing technology, and in particular to a liquid feeding mechanism and mixing device. Background Technology
[0002] In the production process of ceramic products, the mixing process is as follows: dry material addition → dry mixing → liquid addition → wet mixing → drying → cooling → screening and crushing → storage. Figure 1 As shown, the dry powder raw materials are first placed into the mixer 200. After the dry powder raw materials are mixed, a liquid solvent is added. During the liquid addition process, liquid 1, liquid 2, and liquid 3 enter the liquid mixing tank 104 through pipe 101, pipe 202, and pipe 303 respectively as needed for mixing, thereby obtaining a mixed liquid. This mixed liquid is then added to the mixer 200 through pipe 405. At this point, the mixing process enters the wet mixing stage. In the wet mixing stage, the resin raw materials in the dry powder can be fully dissolved in the liquid solvent. As the wet mixing time increases, the viscosity of the liquid decreases and the fluidity increases, and the liquid coats the aggregate and fine powder. However, the above mixing method ultimately converges into a single pipe 405 to transport the liquid into the mixer 200, reducing the uniformity of the liquid coating on the aggregate in the wet mixing stage.
[0003] Therefore, there is an urgent need to provide a liquid feeding mechanism and a mixing device to solve the above problems. Utility Model Content

[0005] Another objective of this invention is to provide a mixing device that improves mixing uniformity and increases mixing efficiency by setting up multiple pipes and multiple angles to transport liquid.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A liquid feeding mechanism is used to add various liquid solvents into the mixer. The liquid feeding mechanism includes multiple liquid inlet pipes, each of which is used to deliver a corresponding liquid solvent into the mixer.

[0029] like Figure 2 As shown, this embodiment provides a liquid feeding mechanism 10 and a mixing device. The mixing device includes a mixer 20 and the aforementioned liquid feeding mechanism 10. The mixer 20 contains dry powder raw materials. After the dry powder raw materials are mixed, the liquid feeding mechanism 10 adds various liquid solvents to the mixer 20. At this time, the mixing process enters the wet mixing stage. In the wet mixing stage, the resin raw materials in the dry powder can be fully dissolved in the liquid solvent. As the wet mixing time increases, the temperature of the refractory raw materials also gradually increases. When the temperature reaches 40 degrees Celsius or above, the viscosity of the liquid solvent decreases and its fluidity increases. At this time, under the stirring of the rotor, it can coat the aggregate and fine powder, thereby achieving mixing.
[0030] The dry powder raw materials can be added directly to the mixer 20 manually, or they can be transported to the mixer 20 by the existing conveying mechanism. The specific structure and working principle of the mixer 20 are existing technologies and will not be described in detail here.
[0031] Specifically, such as Figure 2 As shown, the liquid feeding mechanism 10 includes multiple liquid inlet pipes 11, each of which is used to deliver a corresponding liquid solvent into the mixer 20. The multiple liquid inlet pipes 11 are arranged at intervals in the vertical direction, and the outlet end 116 of each liquid inlet pipe 11 extends into the mixer 20. In the vertical direction, the angle between the liquid outflow direction of each outlet end 116 and the horizontal plane decreases sequentially.
[0032] The liquid feeding mechanism 10 provided in this embodiment delivers different liquid solvents into the mixer 20 simultaneously through multiple inlet pipes 11. Furthermore, the angle between the liquid outflow direction at each outlet 116 and the horizontal plane decreases sequentially from top to bottom. That is, the angle between the liquid outflow direction at the outlet 116 of the uppermost inlet pipe 11 and the horizontal plane is the largest, while the angle between the liquid outflow direction at the lowermost inlet pipe 11 and the horizontal plane is the smallest. The angles between the liquid outflow direction at each of the middle inlet pipes 11 and the horizontal plane decrease sequentially from top to bottom. Therefore, by delivering liquid into the mixer 20 through multiple pipes and at multiple angles, the uniformity of mixing and the mixing efficiency can be improved.
[0033] In this embodiment, as Figure 2 As shown, a detailed explanation is given using three liquid inlet pipes 11 as an example. Specifically, the liquid feeding mechanism 10 includes three liquid inlet pipes 11. From top to bottom, the three liquid inlet pipes 11 are pipe one 111, pipe two 112, and pipe three 113. The angle α1 between the liquid outflow direction at the outlet end 116 of pipe one 111 and the horizontal plane is 165°; the angle α2 between the liquid outflow direction at the outlet end 116 of pipe two 112 and the horizontal plane is 135°; and the angle α3 between the liquid outflow direction at the outlet end 116 of pipe three 113 and the horizontal plane is 105°. Thus, liquid can be added through three pipes at three different angles, improving the uniformity of mixing and increasing mixing efficiency.
[0034] Depend on Figure 2 It can be seen that the cover of the mixer 20 is set at an angle, and three pipes pass through the cover and extend into the mixer 20. Among them, the angle between the outlet end 116 of pipe 111 and the cover of the mixer 20 is 120°, the angle between the outlet end 116 of pipe 212 and the cover of the mixer 20 is 90°, and the angle between the outlet end 116 of pipe 313 and the cover of the mixer 20 is 60°.
[0035] In other embodiments, the number of liquid inlet pipes 11 can be adapted to actual needs, and no specific limitation is made here.
[0036] Specifically, such as Figure 2As shown, the liquid inlet pipe 11 includes an inlet end 114, a horizontal section 115, and an outlet end 116 connected in sequence. The inlet end 114 is connected to a tank containing liquid solvent. The inlet end 114 is perpendicular to the horizontal section 115 and extends upwards. The horizontal section 115 extends horizontally. The outlet end 116 is set at an angle to the horizontal section 115. The horizontal sections 115 of each liquid inlet pipe 11 are parallel and spaced apart in the vertical direction. This arrangement allows multiple liquid inlet pipes 11 to be arranged in a regular manner, reducing space occupation.
[0037] In the prior art, since the temperature of the liquid solvent added to the mixer 20 is usually room temperature, after dissolving into the resin, the viscosity is higher and the fluidity is poor. It takes a longer mixing time to raise the temperature to 40°. Therefore, such a mixing process is inefficient. In addition, the liquid solvent at room temperature has poor fluidity and is easy to remain in the liquid inlet pipe 11, contaminating the liquid inlet pipe 11 and increasing the error of the liquid solvent dosage.
[0038] To address the aforementioned issues, the liquid feeding mechanism 10 provided in this embodiment further includes a heating component 12, which heats the liquid solvent within each inlet pipe 11. Heating the liquid solvent improves its fluidity, reduces contamination of the inlet pipe 11, and enhances dosage accuracy. More importantly, it allows the liquid solvent to fully coat the aggregates and fine powders within a shorter mixing time, thereby increasing mixing efficiency.
[0039] Specifically, such as Figure 2 As shown, the heating assembly 12 includes a nitrogen pipe 121, which surrounds each liquid inlet pipe 11. Specifically, the inlet end 114 of the pipe extends into the nitrogen pipe 121 from the outside, the horizontal part 115 extends into the nitrogen pipe 121, and the outlet end 116 extends out of the nitrogen pipe 121 and into the mixer 20. The nitrogen pipe 121 is provided with a hot nitrogen inlet 122 and a hot nitrogen outlet 123. Both the hot nitrogen inlet 122 and the hot nitrogen outlet 123 are connected to a nitrogen source. Heated nitrogen can be introduced into the nitrogen pipe 121 through the hot nitrogen inlet 122. After heated nitrogen is introduced into the nitrogen pipeline 121, the liquid solvent in each liquid inlet pipeline 11 can be heated instantly, improving the fluidity of the liquid solvent. This not only reduces contamination of the liquid inlet pipeline 11 and improves the accuracy of dispensing, but also allows the liquid solvent to fully coat the aggregate and fine powder in a shorter mixing time, increasing mixing efficiency. The nitrogen after heat exchange returns to the nitrogen source through the hot nitrogen outlet 123, thus circulating continuously. This heating component 12 makes full use of the nitrogen heating device built into the mixing system, realizing the input and output of heated nitrogen and saving energy.
[0040] In other embodiments, the heating component 12 can also be configured to introduce hot liquid into the pipe to achieve a heat exchange process, or an electric heating element can be provided on the inner or outer wall of the pipe to heat the internal space of the pipe.
[0041] In this embodiment, as Figure 2 As shown, the hot nitrogen inlet 122 and the hot nitrogen outlet 123 are respectively located at opposite ends of the nitrogen pipeline 121 along its length. This arrangement increases the flow path of the hot nitrogen, thereby enabling sufficient heat exchange between the hot nitrogen and the liquid solvent in each liquid inlet pipeline 11, and improving the heat exchange efficiency.
[0042] In the prior art, the diameter of the liquid inlet pipe 11 is usually set to 40 mm. In this embodiment, the diameter of each liquid inlet pipe 11 is 20 mm. Reducing the diameter of the liquid inlet pipe 11 facilitates heat exchange between the hot nitrogen gas and the liquid solvent inside the liquid inlet pipe 11, thereby improving the heating efficiency of the liquid.
[0043] In this embodiment, the diameter of the nitrogen pipe 121 is 100 mm. This design increases the space inside the nitrogen pipe 121, increases the flow time of the hot nitrogen, facilitates heat exchange between the hot nitrogen and the liquid solvent in the liquid inlet pipe 11, and improves the heating efficiency of the liquid.
[0044] Furthermore, the temperature of the heating nitrogen introduced into the nitrogen pipeline 121 is 40-50℃, and the motor speed for supplying the heating nitrogen is 3500rpm. By controlling the heating temperature within this range, the liquid solvent in the liquid inlet pipeline 11 can be heated to a suitable temperature without damaging the liquid inlet pipeline 11.
[0045] In summary, by adopting the above technical solution, the liquid solvent can be added from multiple angles. Furthermore, through the heating of the heating component 12, the viscosity of the liquid solvent after being incorporated into the resin is reduced from 3500pc to 600-1000pc, and its fluidity is greatly improved. This allows the liquid solvent to uniformly coat the dry powder aggregate and fine powder in a shorter time, thereby improving the mixing efficiency and shortening the mixing time by 10-15%.
[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
