Description

Technical Field

[0001] This application relates to the field of liquid mixing equipment technology, and in particular to a splash-proof liquid material mixer. Background Technology

[0002] Currently, liquid material stirring technology is widely used in chemical, food, and pharmaceutical fields, mainly to achieve uniform mixing of different liquid components.

[0003] In existing technologies, common methods for mixing liquid materials include mechanical stirring, magnetic stirring, and ultrasonic stirring. Mechanical stirring achieves mixing by driving the stirring blades to rotate with a motor. Its advantages are simple structure and low cost. However, during the mixing process of liquid materials, due to the high-speed rotation of the stirring blades and the effect of centrifugal force, the liquid is prone to splashing out of the mixing container, which not only wastes materials but may also pollute the working environment and even cause injury to operators. Summary of the Invention

[0004] To address the problem that liquids easily splash out of the mixing container due to the high-speed rotation of the mixing blades and the effect of centrifugal force, which not only wastes materials but may also pollute the working environment and even harm operators, this application provides a splash-proof liquid material mixer.

[0005] This application provides a splash-proof liquid material mixer, which adopts the following technical solution: A splash-proof liquid material mixer includes a support frame for overall support and a stirring mechanism for liquid stirring. The stirring mechanism is mounted on the support frame and is provided with a shielding assembly for preventing liquid splashing. The shielding assembly includes a connecting piece, a retaining ring, and a skirt. One end of the connecting piece is connected to the retaining ring, and the other end of the connecting piece is connected to the stirring mechanism. The bottom of the retaining ring is connected to the skirt.

[0006] By adopting the above technical solution, the baffle ring, as the main shielding structure, can directly block the outward splashing of liquid caused by centrifugal force or the impact of the stirring blades during the stirring process, reducing the risk of liquid splashing onto the operator. At the same time, the skirt is a downward-extending structure that can further cover the gap between the baffle ring and the stirring container, preventing liquid from leaking out of the gap, supplementing the shielding range and improving the overall anti-splashing effect.

[0007] Preferably, the skirt edge and the retaining ring are inclined, and the angle between the skirt edge and the retaining ring in the vertical direction is 60 degrees.

[0008] By adopting the above technical solution, the 60-degree tilt angle allows the skirt to extend downwards and open outwards appropriately. Compared with vertical or too small angle designs, it can cover a larger potential splash area. When liquid splashes onto the baffle ring, if a small amount of liquid flows down the inside of the baffle ring, the tilted skirt can guide it into the mixing container below, preventing liquid from dripping down the outside of the skirt or splashing again.

[0009] Preferably, the stirring mechanism includes a drive motor, a sleeve, a mounting ring, a connecting column, and a stirring blade. The drive motor is mounted on a support frame, and the output end of the drive motor is connected to the sleeve. The mounting ring is mounted on the sleeve, and the connecting column is mounted on the sleeve via the mounting ring. One end of the connecting column is connected to the stirring blade, and the stirring blade is located inside the retaining ring and the skirt.

[0010] By adopting the above technical solution, the combination of drive motor, sleeve, mounting ring, connecting column and stirring blade is a modular design. The drive motor directly transmits power through the sleeve, and the mounting ring serves as a fixed carrier for the connecting column, making the installation, disassembly or replacement of the stirring blade easier.

[0011] Preferably, the support frame is provided with an auxiliary mechanism for preventing splashing of the mixer. The auxiliary mechanism includes a connecting plate, a driving component, a screw, a moving block, a connecting rod, and a shielding plate for shielding the top of the liquid tank. The connecting plate is connected to the support frame. The driving component is disposed on the upper connecting plate. The output end of the driving component is connected to the top end of the screw. The bottom end of the screw is rotatably connected to the lower connecting plate. The moving block is threaded onto the surface of the screw. One end of the connecting rod is connected to the moving block. The other end of the connecting rod is connected to the shielding plate. The shielding plate is sleeved and connected.

[0012] By adopting the above technical solution, during stirring, the liquid will not only splash to the sides, but may also overflow or splash from the top of the tank opening due to the upward impact force generated by the high-speed rotation of the stirring blades. The baffle directly covers the opening area at the top of the liquid tank, intercepting the upward splashing liquid at the source and preventing it from escaping from the top by passing over the surrounding baffle components. At the same time, the drive component drives the moving block to move up and down through the screw, thereby adjusting the height of the baffle: for liquid tanks of different heights, the position of the baffle can be adjusted to make it fit precisely against the top of the tank opening.

[0013] Preferably, the auxiliary mechanism is further provided with a scraping component, which may be a rubber plate. The scraping component is located at the bottom of the baffle plate and is used in conjunction with the connecting piece.

[0014] By adopting the above technical solution, when the baffle moves up and down through the auxiliary mechanism, the scraper will move synchronously with the baffle, and its edge can rub against the surface of the connecting piece, thereby scraping off the splashed liquid or residual material adhering to the connecting piece.

[0015] Preferably, the auxiliary mechanism is provided with a guide assembly, which includes a guide slider, a guide post and a fixed plate. The fixed plate is connected to the connecting plate, the two ends of the guide post are connected to the fixed plate, the guide slider is sleeved on the surface of the guide post, and the guide slider is connected to the moving block.

[0016] By adopting the above technical solution, the guide component constrains the guide slider through the guide post, forcing the moving block to move only in the vertical direction of the guide post. The guide slider is connected to the moving block, and the guide post is fixed to the connecting plate by the fixing plate to form a rigid guide track, ensuring that the moving block always moves smoothly in a straight line, avoiding problems such as the tilting of the baffle plate and uneven force on the connecting rod caused by the offset, and ensuring that the baffle plate is accurately aligned with the top of the liquid tank.

[0017] Preferably, the bottom end of the screw is connected to a bearing for assisting the rotation of the screw, and the outer ring of the bearing is connected to the connecting plate.

[0018] By adopting the above technical solution, the outer ring of the bearing is fixed to the connecting plate, and the inner ring is connected to the bottom end of the screw, forming a rigid radial constraint on the bottom end of the screw, ensuring that the screw always rotates stably along the axial direction, and avoiding problems such as wear of the moving block threads and displacement of the connecting rod caused by shaking.

[0019] Preferably, the support frame is provided with a plurality of mounting bolts for fixing the support frame, and the mounting bolts are symmetrically distributed on the support frame.

[0020] By adopting the above technical solution, the mounting bolts are rigidly connected to the foundation to firmly fix the support frame, thus preventing the auxiliary mechanism from shifting and shaking due to the vibration of the mixer, the force during the adjustment of the baffle plate, or the impact of liquid splash during operation.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting the baffle ring as the main shielding structure, it can directly block the outward splashing of liquid caused by centrifugal force or the impact of the stirring blades during the stirring process, reducing the risk of liquid splashing onto the operator. At the same time, the skirt is a downward extending structure, which can further cover the gap between the baffle ring and the stirring container, preventing liquid from leaking from the gap, supplementing the shielding range and improving the overall anti-splashing effect. 2. An auxiliary mechanism is installed to prevent liquid from splashing out or spraying from the top of the tank opening during stirring. This is because the liquid will not only splash to the sides during stirring, but also may overflow or spray due to the upward impact force generated by the high-speed rotation of the stirring blades. The baffle directly covers the opening area at the top of the liquid tank, intercepting the upward splashing liquid at the source and preventing it from escaping from the top by bypassing the surrounding baffle components. At the same time, the drive component drives the moving block to move up and down through the screw, thereby adjusting the height of the baffle: for liquid tanks of different heights, the position of the baffle can be adjusted to make it fit precisely against the top of the tank opening. 3. By setting up a scraping component, when the baffle moves up and down through the auxiliary mechanism, the scraping component will move synchronously with the baffle, and its edge can rub against the surface of the connecting piece, thereby scraping off the splashed liquid or residual material adhering to the connecting piece.

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail.

[0025] This application discloses a splash-proof liquid material mixer.

[0026] Reference Figure 1 and Figure 2A splash-proof liquid material mixer includes a support frame 100 for overall support and a stirring mechanism 200 for liquid stirring. The stirring mechanism 200 is fixedly connected to the support frame 100 on the side closest to it. A shielding assembly 300 is connected to the stirring mechanism 200 to prevent liquid splashing. The shielding assembly 300 includes a connecting piece 310, a retaining ring 320, and a skirt 330. The top end of the connecting piece 310 is connected to the stirring mechanism 200, and the connecting piece 310 is arc-shaped. The bottom end of the connecting piece 310 is connected to the retaining ring 320. The ring 320 is fixedly connected, and the bottom end of the retaining ring 320 is fixedly connected to the skirt 330. Both the retaining ring 320 and the skirt 330 are circular. By setting the retaining ring 320 as the main shielding structure, it can directly block the outward splashing of liquid caused by centrifugal force or the impact of the stirring blades 250 during the stirring process, reducing the risk of liquid splashing onto the operator. At the same time, the skirt 330 is a downward extending structure, which can further cover the gap between the retaining ring 320 and the stirring container, preventing liquid from leaking from the gap, supplementing the shielding range and improving the overall anti-splashing effect.

[0027] refer to Figure 2 and Figure 3 The skirt 330 and the retaining ring 320 are set at an inclination, and the skirt 330 is inclined outward. The angle between the skirt 330 and the retaining ring 320 in the vertical direction is 60 degrees. The 60-degree inclination angle allows the skirt 330 to extend downward and open outward appropriately. Compared with a vertical or too small angle design, it can cover a larger potential splash area. When liquid splashes to the retaining ring 320, if a small amount of liquid flows down along the inner side of the retaining ring 320, the inclined skirt 330 can guide it into the stirring container below, avoiding liquid dripping or secondary splashing along the outer side of the skirt 330.

[0028] refer to Figure 3 The stirring mechanism 200 includes a drive motor 210, a sleeve 220, a mounting ring 230, a connecting column 240, and a stirring blade 250. The drive motor 210 is fixedly connected to the support frame 100 on the side closest to it. The output end of the drive component 420 is fixedly connected to the top end of the sleeve 220, and the bottom end of the sleeve 220 is fixedly connected to the mounting ring 230. The connecting column 240 is mounted on the sleeve 220 via the mounting ring 230, and the bottom end of the connecting column 240 is connected to the stirring blade 250. The stirring blade 250 is fixedly connected to the retaining ring 320 and the skirt 330, so that the retaining ring 320 and the skirt 330 cover the stirring blade 250. The combination of the drive motor 210, the sleeve 220, the mounting ring 230, the connecting column 240 and the stirring blade 250 is a modular design. The drive motor 210 directly transmits power through the sleeve 220, and the mounting ring 230 serves as a fixed carrier for the connecting column 240, making the installation, disassembly or replacement of the stirring blade 250 easier.

[0029] refer to Figure 4 The support frame 100 is equipped with an auxiliary mechanism 400 to prevent splashing of the mixer. The auxiliary mechanism 400 includes a connecting plate 410, a driving component 420, a screw 430, a moving block 440, a connecting rod 450, and a baffle plate 460 for shielding the top of the liquid tank. The connecting plate 410 is fixedly connected to the support frame 100 on the side closest to the support frame 100. The driving component 420 is mounted on the upper connecting plate 410, and the output end of the driving component 420 is fixedly connected to the top end of the screw 430. The bottom end of the screw 430 is rotatably connected to the lower connecting plate 410. The moving block 440 is threaded onto the surface of the screw 430, and both sides of the moving block 440 are fixedly connected to the connecting rod 450. The end of 50 away from the moving block 440 is fixedly connected to the baffle plate 460, which is sleeved on the surface of the connecting column 240 and the mounting ring 230. During stirring, the liquid will not only splash to the sides, but may also overflow or splash from the top of the tank opening due to the upward impact force generated by the high-speed rotation of the stirring blade 250. The baffle plate 460 directly covers the opening area at the top of the liquid tank, intercepting the upward splashing liquid at the source and preventing it from escaping from the top through the peripheral baffle assembly 300. At the same time, the drive component 420 drives the moving block 440 to move up and down through the screw 430, thereby adjusting the height of the baffle plate 460. For liquid tanks of different heights, the position of the baffle plate 460 can be adjusted to make it fit precisely against the top of the tank opening.

[0030] refer to Figure 4 The auxiliary mechanism 400 is also equipped with a scraper 470, which can be a rubber plate. The scraper 470 is installed at the bottom of the baffle plate 460 and works in conjunction with the connecting piece 310 to scrape the surface of the connecting piece 310. When the baffle plate 460 moves up and down through the auxiliary mechanism 400, the scraper 470 moves synchronously with the baffle plate 460, and its edge can rub against the surface of the connecting piece 310 to scrape off the splashed liquid or residual material adhering to the connecting piece 310.

[0031] The auxiliary mechanism 400 is equipped with a guide assembly 480, which includes a guide slider 481, a guide post 482, and a fixing plate 483. The fixing plate 483 is fixedly connected to the connecting plate 410 on the side closest to it. Both ends of the guide post 482 are fixedly connected to the fixing plate 483. The guide slider 481 is sleeved onto the surface of the guide post 482, and the side of the guide slider 481 closest to the support frame 100 is fixedly connected to the moving block 440, providing vertical guidance to the moving block 440. The guide block 440 is forced to move only along the vertical direction of the guide block 482 by the guide column 482 constraining the guide slider 481 of the component 480. The guide slider 481 is connected to the moving block 440, and the guide column 482 is fixed on the connecting plate 410 by the fixing plate 483 to form a rigid guide track, ensuring that the moving block 440 always moves smoothly along a straight line, avoiding problems such as the tilting of the baffle plate 460 and uneven force on the connecting rod 450 caused by offset, and ensuring that the baffle plate 460 is accurately aligned with the top of the liquid tank.

[0032] The bottom end of the screw 430 is connected to a bearing 490 for assisting the rotation of the screw 430. The outer ring of the bearing 490 is connected to the connecting plate 410. The outer ring of the bearing 490 is fixed to the connecting plate 410, and the inner ring is connected to the bottom end of the screw 430, forming a rigid radial constraint on the bottom end of the screw 430. This ensures that the screw 430 always rotates stably along the axial direction, avoiding problems such as thread wear of the moving block 440 and displacement of the connecting rod 450 caused by shaking.

[0033] refer to Figure 4 The support frame 100 is provided with a number of mounting bolts 110 for fixing the support frame 100. The mounting bolts 110 are symmetrically distributed on the support frame 100. The mounting bolts 110 are rigidly connected to the foundation to firmly fix the support frame 100, so as to prevent the auxiliary mechanism 400 from being displaced and shaking due to the vibration of the mixer, the force of the baffle plate 460 during adjustment, or the impact of liquid splash during operation.

[0034] The implementation principle of this application embodiment is as follows: In implementation, by placing the liquid container at the bottom of the stirring mechanism 200, the stirring blade 250, connecting piece 310, retaining ring 320, and skirt 330 on the stirring mechanism 200 are all located inside the container. The driving component 420 on the auxiliary mechanism 400 is started. The driving component 420 drives the screw 430 to rotate. The screw 430 drives the moving block 440 to rotate. The moving block 440 drives the connecting rod 450 to move. The connecting rod 450 drives the baffle plate 460 to move, so that the baffle plate 460 covers the top of the container. The drive motor 210 on the stirring mechanism 200 is started. The drive motor 210 drives the connecting column 240 to rotate. The connecting column 240 drives the stirring blade 250 to stir the liquid. At the same time, the connecting piece 310, retaining ring 320, and skirt 330 shield the area around the stirring blade 250, which can directly prevent the liquid from splashing outward due to centrifugal force or the impact of the stirring blade 250 during the stirring process, reducing the risk of liquid splashing onto the operator.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
