Description

Technical Field

[0001] This utility model relates to the field of water-based solvent-free new material production technology, and in particular to a mixing device for the production of water-based nanomaterials. Background Technology

[0002] The mixing device for the production of water-based nanomaterials is a highly efficient and environmentally friendly production equipment, which is of great significance for promoting the development of the nanomaterials industry.

[0003] In the prior art, an air pump is used to deliver air through the air holes at the bottom of the stirring shaft into the raw material liquid being stirred, so that the air bubbles output from the air holes come into contact with the raw material, thereby allowing the raw material to be fully mixed inside the mixing device, thus solving the problem of insufficient mixing of raw materials by the mixing device.

[0004] However, in practical applications, since the water-based nanomaterials may contain corrosive components, the inner wall of the mixing device may be severely worn after long-term use. In this case, the entire mixing device needs to be repaired or replaced. However, the inner wall of the existing mixing device is usually fixed inside the device with multiple sets of bolts, which makes the process of replacing the inner wall time-consuming and laborious, and is not conducive to improving the replacement efficiency of the inner wall.

[0005] Therefore, this application provides a mixing apparatus for the production of aqueous nanomaterials to meet the requirements. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and propose a mixing device for the production of aqueous nanomaterials.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a mixing device for the production of aqueous nanomaterials, comprising:

[0008] Mixing tank;

[0009] An inner wall protection assembly is placed inside the mixing tank. The inner wall protection assembly includes a main protection plate disposed on the inner wall of the mixing tank and secondary protection plates disposed on both sides of the main protection plate. An elastic snap-fit ​​block is fixedly connected to the side of the main protection plate near the secondary protection plate, and a snap-fit ​​groove is opened on the side of the secondary protection plate near the elastic snap-fit ​​block. The main protection plate is snapped into the secondary protection plate through the elastic snap-fit ​​block and the snap-fit ​​groove.

[0010] A fixing component is placed on top of the inner wall protection component and is used to reinforce the connection between the main protection plate and the secondary protection plate. The fixing component includes a movable block disposed on the secondary protection plate near the top of the mixing tank. A connector is fixedly connected to the side of the mixing tank near the movable block. A threaded rod is rotatably connected to the side of the movable block near the connector. The threaded rod is threadedly connected to the connector. The movable block is slidably connected to the mixing tank through the connector and the threaded rod.

[0011] In a preferred embodiment, a fixing block is fixedly connected to the bottom of the inner wall of the mixing tank, and the fixing block is engaged with a secondary protective plate near the bottom of the mixing tank.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it keeps the interior of the main protective plate and the secondary protective plate smooth, thus avoiding disturbance to the stirring of the water-based nanomaterials.

[0013] In a preferred embodiment, the elastic snap-fit ​​block is an annular flat-headed conical structure, the diameter of the top of the snap-fit ​​groove is smaller than the diameter of the top of the elastic snap-fit ​​block, and the diameter of the bottom of the snap-fit ​​groove is larger than the diameter of the bottom of the elastic snap-fit ​​block.

[0014] The beneficial effect of adopting the above-mentioned further solution is that it can increase the contact area between the elastic snap block and the snap slot, and further strengthen the connection between the main protection plate and the secondary protection plate.

[0015] In a preferred embodiment, the side of the secondary protective plate away from the main protective plate is a sloping structure, and the movable block and the fixed block are both provided with an inner groove matching the sloping surface on the side near the secondary protective plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it further strengthens the main protection plate and the secondary protection plate, which is conducive to further improving the stability of the mixing device.

[0017] In a preferred embodiment, a rubber pad is fixedly connected to the side of both the main protection plate and the secondary protection plate near the mixing tank, and the thickness of the rubber pad is greater than the thickness of the inclined surface on the secondary protection plate.

[0018] The beneficial effects of adopting the above-mentioned further solution are: it makes the main protective plate and the secondary protective plate more firmly fixed, and the main protective plate seals the gap between the inner tank and the secondary protective plate, preventing water-based nanomaterials from corroding the inner wall of the mixing tank from the gap.

[0019] In a preferred embodiment, both the main protective plate and the secondary protective plate have an anti-corrosion coating on the side away from the rubber pad.

[0020] The beneficial effects of adopting the above-mentioned further solutions are: to further improve the anti-corrosion performance of the main protective plate and the secondary protective plate, and to increase the service life of the main protective plate and the secondary protective plate.

[0021] In a preferred embodiment, a sealing top cover is provided on the side of the mixing tank near the movable block, and the sealing top cover has an L-shaped cross-section.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the sealed top cover wraps around the outer wall of the top of the mixing tank, which helps to maintain the airtightness of the mixing tank.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] 1. By setting up an inner wall protection component, the main protection plate and the secondary protection plate are stacked inside the mixing tank. The main protection plate and the secondary protection plate can isolate the inner wall of the mixing tank from the water-based nanomaterials, effectively preventing the water-based nanomaterials from directly corroding the inside of the mixing tank. Pushing the secondary protection plate located at the top of the mixing tank upwards allows the elastic locking block to separate from the locking groove. In this way, the secondary protection plate and the main protection plate can be smoothly removed from the inside of the mixing tank in sequence. This maintains the protection of the inner wall of the mixing tank and helps to improve the replacement efficiency of the main protection plate and the secondary protection plate.

[0025] 2. By setting up a fixing component, screws are used to firmly fix the connecting parts to the mixing tank to further stabilize the relevant structure. When the rotating threaded rod starts to rotate, according to the principle of thread transmission, the threaded rod will move downward along the thread trajectory. The threaded rod will then drive the connected movable block to move downward synchronously. The movable block will then apply a compressive force to the secondary protective plate. Thanks to this compressive force, the main protective plate and the secondary protective plate stacked inside the mixing tank can be firmly fixed, making the connection between the two tighter and more reliable, and reducing gaps. In this way, the structural stability of the entire mixing device is significantly improved. During daily operation, it will not easily loosen or shift, further enhancing the protective effect of the inner wall protection component. It can more effectively isolate the water-based nanomaterials from contact with the inner wall of the mixing tank, reduce the risk of corrosion of the inner wall, and extend the service life of the mixing tank.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0035] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a mixing device for the production of water-based nanomaterials, including: a mixing tank 1, the mixing tank 1 including a motor, a rotating shaft, and a stirring rod, the motor being installed on the top of a sealed top cover 31, the rotating shaft being fixedly connected to the output end of the motor and perpendicular to the inside of the mixing tank 1, and the stirring rod being fixed on the rotating shaft for stirring the raw materials inside the mixing tank 1, so that the raw materials are mixed together;

[0036] like Figure 1 - Figure 3 As shown, the inner wall protection component 2 is placed inside the mixing tank 1. The inner wall protection component 2 includes a main protection plate 21 disposed on the inner wall of the mixing tank 1 and a secondary protection plate 22 disposed on both sides of the main protection plate 21. An elastic snap-fit ​​block 24 is fixedly connected to the side of the main protection plate 21 near the secondary protection plate 22. A snap-fit ​​groove 25 is opened on the side of the secondary protection plate 22 near the elastic snap-fit ​​block 24. The main protection plate 21 is snapped into the secondary protection plate 22 through the elastic snap-fit ​​block 24 and the snap-fit ​​groove 25.

[0037] like Figure 2 - Figure 4As shown, the fixing component 3 is placed on top of the inner wall protection component 2 and is used to reinforce the connection between the main protection plate 21 and the secondary protection plate 22. The fixing component 3 includes a movable block 32 disposed on the secondary protection plate 22 near the top of the mixing tank 1. A connector 35 is fixedly connected to the side of the mixing tank 1 near the movable block 32. A threaded rod 36 is rotatably connected to the side of the movable block 32 near the connector 35. The threaded rod 36 is threadedly connected to the connector 35. The movable block 32 is slidably connected to the mixing tank 1 through the connector 35 and the threaded rod 36. By stacking the main protection plate 21 and the secondary protection plate 22 inside the mixing tank 1, the main protection plate 21 and the secondary protection plate 22 isolate the inner wall of the mixing tank 1 from the water-based nanomaterial, preventing the water-based nanomaterial from directly corroding the inside of the mixing tank 1. When the main protection plate 21 and the secondary protection plate 22 are used for a long time, their own inner walls will be corroded. At this time, the secondary protection plate 22 on the top of the mixing tank 1 is pushed. The secondary protection plate 22 moves upward, causing the elastic locking block 24 to separate from the locking groove 25. This facilitates the sequential removal of the secondary protection plate 22 and the main protection plate 21 from the inside of the mixing tank 1. This solves the problem that the inner wall is usually fixed inside the device with multiple sets of bolts, which makes the replacement process of the inner wall time-consuming and laborious. It helps to maintain the protection effect of the inner wall of the mixing tank 1 while improving the replacement efficiency of the main protection plate 21 and the secondary protection plate 22. Furthermore, the connecting piece 35 is fixed to the mixing tank 1 by using screws. When the threaded rod 36 rotates, the threaded rod 36 moves downward through its own thread and the thread on the connecting piece 35, driving the movable block 32 to squeeze the secondary protection plate 22, fixing the main protection plate 21 and the secondary protection plate 22 inside the mixing tank 1. This makes the connection between the main protection plate 21 and the secondary protection plate 22 more secure and reduces the gap between the main protection plate 21 and the secondary protection plate 22, thereby improving the stability of the mixing device and further improving the protection effect of the inner wall protection component 2.

[0038] Furthermore, such as Figure 2 As shown: A fixing block 33 is fixedly connected to the bottom of the inner wall of the mixing tank 1. The fixing block 33 is engaged with the secondary protection plate 22 near the bottom of the mixing tank 1. By engaging the secondary protection plate 22 at the bottom with the fixing block 33, the movable block 32, the fixing block 33, the elastic engaging block 24, and the engaging groove 25 cooperate. The fixing block 33 first fixes the bottom of the secondary protection plate 22, and the elastic engaging block 24 and the engaging groove 25 fix the main protection plate 21 and the secondary protection plate 22. Then, the movable block 32 fixes the top plate of the secondary protection plate 22, so that the main protection plate 21 and the secondary protection plate 22 are tightly attached to the inner wall of the mixing tank 1, so that the interior of the main protection plate 21 and the secondary protection plate 22 remains smooth, avoiding disturbance to the stirring of the water-based nanomaterials.

[0039] Furthermore, such as Figure 3As shown: The elastic snap-fit ​​block 24 is an annular flat-headed conical structure. The diameter of the top of the snap-fit ​​groove 25 is smaller than the diameter of the top of the elastic snap-fit ​​block 24, and the diameter of the bottom of the snap-fit ​​groove 25 is larger than the diameter of the bottom of the elastic snap-fit ​​block 24. By setting the conical elastic snap-fit ​​block 24, when the elastic snap-fit ​​block 24 contacts the snap-fit ​​groove 25, the snap-fit ​​groove 25 presses the elastic snap-fit ​​block 24 downward. Since the elastic snap-fit ​​block 24 is elastic, it deforms to both sides after being compressed, thereby sealing the inside of the snap-fit ​​groove 25. Moreover, the two sides of the elastic snap-fit ​​block 24 are inclined, which can increase the contact area between the elastic snap-fit ​​block 24 and the snap-fit ​​groove 25, further strengthening the connection between the main protection plate 21 and the secondary protection plate 22.

[0040] Furthermore, such as Figure 3 As shown: The side of the secondary protection plate 22 away from the main protection plate 21 is a sloping structure. The movable block 32 and the fixed block 33 are both provided with inner grooves 34 that match the sloping surface on the side near the secondary protection plate 22. By setting the sloping surface on the secondary protection plate 22 that matches the inner groove 34, when the movable block 32 moves downward, the inner groove 34 on the movable block 32 and the fixed block 33 cooperate to squeeze the secondary protection plate 22 against the inner wall of the mixing tank 1, thereby further reinforcing the main protection plate 21 and the secondary protection plate 22, which is conducive to further improving the stability of the mixing device.

[0041] Furthermore, such as Figure 3 As shown: Rubber pads 23 are fixedly connected to the side of the main protection plate 21 and the secondary protection plate 22 near the mixing tank 1. The thickness of the rubber pads 23 is greater than the thickness of the inclined surface of the secondary protection plate 22. By fixing the rubber pads 23 to the main protection plate 21 and the secondary protection plate 22, when the movable block 32 fixes the secondary protection plate 22, the rubber pads 23 increase the coefficient of friction between the secondary protection plate 22, the main protection plate 21 and the mixing tank 1, making the main protection plate 21 and the secondary protection plate 22 more firmly fixed. The main protection plate 21 seals the gap between the inner tank 34 and the secondary protection plate 22, preventing water-based nanomaterials from corroding the inner wall of the mixing tank 1 from the gap.

[0042] Furthermore, such as Figure 3 As shown: both the main protection plate 21 and the secondary protection plate 22 are provided with an anti-corrosion coating 26 on the side away from the rubber pad 23. By spraying the anti-corrosion coating 26 onto the main protection plate 21 and the secondary protection plate 22, the anti-corrosion performance of the main protection plate 21 and the secondary protection plate 22 is further improved, and the service life of the main protection plate 21 and the secondary protection plate 22 is increased.

[0043] Furthermore, such as Figure 4As shown: A sealing top cover 31 is provided on the side of the mixing tank 1 near the movable block 32. The sealing top cover 31 has an L-shaped cross section. The sealing top cover 31 is fixed to the top of the mixing tank 1 by using bolts. At this time, the internal reinforcing threaded rod 36 of the sealing top cover 31 is stuck, and the sealing top cover 31 covers the outer wall of the top of the mixing tank 1, which helps to maintain the airtightness of the mixing tank 1.

[0044] Working principle: such as Figure 1 - Figure 4 As shown, after prolonged use, the inner walls of the main protective plate 21 and the secondary protective plate 22 of the mixing tank 1 suffer severe corrosion. Therefore, it is necessary to replace the main protective plate 21 and the secondary protective plate 22. After opening the sealing top cover 31, remove the connecting threaded rod 36 of the connector 35 from the top of the mixing tank 1. Push the main protective plate 21 and the secondary protective plate 22 out of the mixing tank 1 in sequence and replace them. Then, place the new secondary protective plate 22 inside the mixing tank 1 and engage it with the inner groove 34 on the fixing block 33 to improve the replacement efficiency of the main protective plate 21 and the secondary protective plate 22. Finally, place the main protective plate 21 and the other secondary protective plate 22 into the mixing tank 1. The elastic locking block 24 and the locking groove 25 are interlocked to fix the main protection plate 21 and the two auxiliary protection plates 22. Then, the connecting piece 35 is installed on the mixing tank 1 by bolts. The rotating threaded rod 36 moves downward through its own thread and the thread line on the connecting piece 35, which drives the movable block 32 to squeeze the auxiliary protection plate 22. The movable block 32 cooperates with the inner groove 34 on the fixed block 33 to squeeze the auxiliary protection plate 22 against the inner wall of the mixing tank 1. The rubber pad 23 increases the coefficient of friction between the auxiliary protection plate 22, the main protection plate 21 and the mixing tank 1, making the main protection plate 21 and the auxiliary protection plate 22 more firmly fixed, thereby improving the stability of the mixing device and further improving the protective effect of the inner wall protection component 2.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
