Description

Technical Field

[0001] This application relates to the technical field of defoaming for multilayer ceramic chip capacitors, and in particular to an automatic cleaning device for a defoaming tank. Background Technology

[0002] In industrial production processes, defoaming tanks are widely used in chemical, pharmaceutical, food processing, and electronics manufacturing industries to remove air bubbles or tiny particles from liquids, ensuring product quality and process stability. However, residues easily adhere to the walls of defoaming tanks, such as solidified air bubble residue, sticky substances, and chemical deposits. If these residues are not cleaned in a timely manner, they can affect the quality of subsequent production and may lead to reduced equipment operating efficiency or even malfunction.

[0003] In the production process of chip multilayer ceramic capacitors, the internal electrodes and dielectric layers use high solid content metal pastes (such as silver paste, nickel paste) or ceramic pastes (such as BaTiO3 dielectric paste). These pastes are prone to air bubbles during stirring, grinding, and conveying. Degassing tanks are used to remove air bubbles from the paste by combining negative pressure vacuum, stirring, and other methods.

[0004] After discharging, the slurry residue on the walls of traditional defoaming tanks has dried and hardened. This residue can only be dissolved by wetting it with anhydrous ethanol and scraping it off. Operators can only use copper wire brushes to scrub it. When cleaning manually, operators need to wear gas masks, bend over and use copper wire brushes to bring up the anhydrous ethanol from the bottom of the tank to scrape the tank walls. This is not only inefficient, but also poses a great risk to the operator's personal safety. Bending over for a long time poses a risk of lumbar muscle strain, and the volatilization of anhydrous ethanol poses a risk of respiratory diseases due to inhalation of aerosols.

[0052] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, a detailed description of specific embodiments of this application is provided below. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0053] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0054] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0056] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0057] To address the technical problems in the background art, this application provides an automatic cleaning device for a defoaming tank, which can automatically clean the tank wall.

[0058] like Figure 1-6 As shown, in one embodiment, the automatic cleaning device 100 for the defoaming tank includes a scrubbing mechanism 10, which is detachably mounted on the stirring shaft 210 of the defoaming tank 200. The stirring shaft 210, during the defoaming process, rotates to drive the stirring paddle 211 on it to stir the slurry inside the defoaming tank 200. During the defoaming process, the scrubbing mechanism 10 is not required to be mounted on the defoaming tank 200; instead, it is detachably mounted on the stirring shaft 210 after the defoaming process is completed to scrub the tank wall.

[0059] Specifically, such as Figure 2 As shown, the scrubbing mechanism 10 includes a connecting component 11, a hanging arm 12, and a scrubbing component 13. The connecting component 11 is fixed to the stirring spindle 210, one end of the hanging arm 12 is connected to the connecting component 210, and the scrubbing component 13 is connected to the other end of the hanging arm 12. The scrubbing component 13 is used to clean the tank wall of the defoaming tank.

[0060] Preferably, the connecting component 11 is also detachably fixed to the stirring spindle 210. The brushing component 13 cleans the tank wall by brushing elements provided thereon. Specifically, the brushing elements can be metal or other materials, such as copper wire brushes.

[0061] The automatic cleaning device for the defoaming tank in this embodiment of the application achieves automatic cleaning of the tank wall by fixing the scrubbing mechanism to the stirring spindle of the defoaming tank. Since the scrubbing mechanism is detachably mounted on the stirring spindle, it can be quickly installed during use and easily disassembled when not in use, facilitating replacement or maintenance. The detachable connection structure allows for quick assembly or disassembly of the hanging arm and connecting components, improving the equipment's versatility and applicability to defoaming tanks of different specifications. Because the scrubbing component acts directly on the tank wall, it effectively scrapes away stubborn residues, preventing residues from affecting subsequent production. The scrubbing component, fixed to the hanging arm, rotates with the stirring spindle, achieving uniform, full-coverage scrubbing, avoiding cleaning dead zones, and improving cleaning effectiveness.

[0062] In an alternative embodiment, such as Figures 3-5 As shown, the scrubbing assembly 10 includes an elastic support base 131, a scrubbing support plate 133, and a scrubbing element 134. The scrubbing element 134 is fixed on the scrubbing support plate 133 and is used to contact the tank wall of the defoaming tank 200 and scrape off the residue.

[0063] In this embodiment, the elastic support base 131 is fixedly connected to the hanging arm 12, and the scrubbing support plate 133 is connected to the elastic support base 131 through an elastic connection structure. The elastic connection structure allows the scrubbing support plate 133 to approach or move away from the elastic support base 131 along the radial direction of the defoaming tank 200.

[0064] The automatic cleaning device for the defoaming tank in this embodiment has a brush support plate connected to an elastic support base via an elastic connection structure. When there are local unevenness, curvature changes, or different thicknesses of residue on the tank wall, the brush support plate can automatically adjust its position to ensure that the brushing element is always in close contact with the tank wall, thereby enhancing the scraping and cleaning ability. It can adapt to the slight deformation of different tank walls and improve the cleaning quality.

[0065] Because the scrubbing support plate has radial elastic movement capability, the elastic connection structure can automatically adjust the contact pressure when the scrubbing element comes into contact with the tank wall, ensuring appropriate scraping force so as not to damage the tank wall and to effectively clean it. This structure avoids excessive compression or excessive relaxation, which makes the scrubbing components last longer and reduces the maintenance cost of long-term operation of the equipment.

[0066] Preferred, such as Figures 3-5 As shown, the elastic connection structure includes an elastic support unit and a guide unit. Specifically, the elastic support unit includes multiple springs 132, which are connected between the elastic support base 131 and the scrubbing support plate 133. The springs 132 can be directly fixed to the surfaces of the elastic support base 131 and the scrubbing support plate 133. In a preferred embodiment, for ease of installation, one or all of the elastic support base 131 and the scrubbing support plate 133 are provided with receiving holes to accommodate the springs 132.

[0067] The guiding unit includes a guide post 135 and a guide hole 136. The guide post 135 is disposed on one of the elastic support base 131 and the brushing support plate 133, and the guide hole 136 is disposed on the other. The guide post 135 extends into the guide hole 136 to restrict the movement direction of the brushing support plate 133. Figures 3 to 5 In the embodiments described, the guide post 135 is set on the brushing support plate 133 and the guide hole 136 is set on the elastic support seat 131 as an example.

[0068] To limit the movement of the scrubbing support plate 133 and prevent it from detaching from the elastic support base 131, in one embodiment, such as Figure 4-5 As shown, the scrubbing assembly also includes a limiting unit, which includes a limiting hole 137 and a limiting member 138. The limiting hole 137 is disposed on the elastic support base 131. The limiting member 138 partially passes through the limiting hole 137 and is fixedly connected to the scrubbing support plate 133. The limiting member 138 can move back and forth relative to the limiting hole 137. The portion of the limiting member 138 that does not pass through the limiting hole 137 has a limiting part with a diameter larger than that of the limiting hole 137, so that the limiting member 138 will not completely pass through the limiting hole 137.

[0069] Preferred, such as Figure 4-5 As shown, the limiting member 138 is a bolt, which includes a bolt head 1381, a non-threaded section 1382, and a threaded section 1383. The threaded section 1383 is threadedly connected to the threaded hole 1331 provided on the brushing support plate 133. The diameter of the bolt head 1381 is larger than that of the limiting hole 137 and is located on the side of the limiting hole 137 away from the brushing support plate 133. The non-threaded section 1382 is located between the bolt head 1381 and the threaded section 1383, passes through the limiting hole 137, and can move back and forth relative to the limiting hole 137.

[0070] In this embodiment, when the spring 132 supports the brushing support plate 133 away from the elastic support seat 131, and drives the limiting member 138 to move forward until the bolt head 1381 abuts against the elastic support seat 131, the brushing support plate 133 is limited to the position furthest from the elastic support seat 131 and cannot move further away, so that the brushing support plate 133 will not fall off.

[0071] In one specific embodiment, such as Figure 3-5As shown, the connecting assembly 11 includes a first fixing member 111 and a second fixing member 112. The first fixing member 111 has a first arc-shaped clamping groove 1111; the second fixing member 112 has a second arc-shaped clamping groove 1121 that matches the first arc-shaped clamping groove 1111. When the first fixing member 111 and the second fixing member 112 are fixedly connected, the first arc-shaped clamping groove 1111 and the second arc-shaped clamping groove 1121 cooperate to form a complete clamping hole for fixing the stirring spindle 210 of the defoaming tank. Preferably, both the first arc-shaped clamping groove 1111 and the second arc-shaped clamping groove 1121 are semi-circular.

[0072] In this embodiment, the first fixing member 111 and the second fixing member 112 can be fixed together by fastening, thereby fixing them to the stirring spindle 210. By fastening the first fixing member 111 and the second fixing member 112 together, or by disassembling and separating them, the scrubbing mechanism 10 can be fixed to the stirring spindle 210 or removed from the stirring spindle 210.

[0073] In one specific embodiment, such as Figure 3-5 As shown, the detachable connection structure connecting the connecting assembly 11 and the hanging arm 12 includes a slot 1112 and a plug-in part 121. The slot 1112 is disposed on the first fixing member 111; the plug-in part 121 matches the slot 1112 and is disposed at the end of the hanging arm 12; the hanging arm 12 is inserted into the slot 1112 through the plug-in part 121, thereby being fixedly connected to the connecting assembly 11.

[0074] In one embodiment, such as Figures 1-7 As shown, the automatic cleaning device 100 for the defoaming tank also includes a spray system, which includes a pneumatic diaphragm pump 21 and a spray pipe 22. The pneumatic diaphragm pump 21 is used to supply cleaning fluid to the spray pipe. Specifically, the spray pipe 22 is connected to the pneumatic diaphragm pump 21 via a delivery pipe 23; the spray pipe 22 is arranged in a ring along the top of the defoaming tank 200 and is used to spray cleaning fluid into the defoaming tank 200.

[0075] like Figure 6 and Figure 7 As shown, the spray pipe 22 is provided with multiple spray holes, which are evenly distributed along the pipe axis of the spray pipe 22 and face the tank wall of the defoaming tank 200. In a preferred embodiment, the spray holes are arranged at an angle downwards so that the cleaning liquid flows downwards along the tank wall and will not be splashed into the tank.

[0076] Preferably, the cleaning solution is anhydrous ethanol, such as... Figure 1 As shown, the pneumatic diaphragm pump 21 draws anhydrous ethanol from the cleaning solution tank 26 and delivers it to the spray pipe 22. In this embodiment, anhydrous ethanol is a polar organic solvent that can effectively dissolve the metal electrode slurry or ceramic slurry on the tank wall of the defoaming tank 200.

[0077] like Figure 1 and Figure 6 As shown, in one embodiment, the spray system further includes a main liquid supply pipe 24 and a branch pipe 25. The main liquid supply pipe 24 is connected to the pneumatic diaphragm pump 21 through a delivery pipe 23. The branch pipe 25 is branched off from the main liquid supply pipe 24 and connected to the spray pipe 22. The branch pipe 25 is arranged symmetrically along the top of the defoaming tank 200.

[0078] In a preferred embodiment, such as Figure 6 and Figure 7 As shown, the spray holes on the spray pipe 22 include a first group of spray holes 221 and a second group of spray holes 222. The first group of spray holes 221 is arranged in a ring at a first height position of the spray pipe 22; the second group of spray holes 222 is arranged in a ring at a second height position of the spray pipe 22 and is staggered with the first group of spray holes 221.

[0079] In this embodiment, by setting two sets of spray holes at different heights and arranging them evenly and alternately, the spraying effect can be made more uniform.

[0080] In a preferred embodiment, to achieve better control of the cleaning fluid flow rate, the automatic cleaning device 100 for the defoaming tank also includes a controller (not shown) and a distance sensor (not shown). The controller is connected to the drive motor of the pneumatic diaphragm pump 21, the distance sensor and the stirring spindle 210. The distance sensor is mounted on the elastic support 131 and is used to detect the interval distance between the elastic support 131 and the brushing support plate 133 during use.

[0081] The controller receives the interval distance signal sent by the distance sensor and controls the spray pressure of the pneumatic diaphragm pump 21 and the rotation speed of the stirring shaft 210 according to the interval distance. The larger the interval distance, the smaller the spray pressure output by the pneumatic diaphragm pump 21 and the smaller the rotation speed of the stirring shaft 210 controlled by the controller; the smaller the interval distance, the larger the spray pressure output by the pneumatic diaphragm pump 21 and the larger the rotation speed of the stirring shaft controlled by the controller.

[0082] Specifically, the distance sensor can be a non-contact displacement sensor, which is mounted on the elastic support 131 and faces the brush support plate 133 to detect the distance between the two, and transmits the distance signal to the controller via a wireless (Bluetooth) sensor.

[0083] In this embodiment, the distance between the elastic support base 131 and the scrubbing support plate 133 is detected by a distance sensor, which allows for real-time monitoring of the scrubbing assembly's contact with the tank wall. When the residue on the tank wall is thick, the scrubbing support plate 133 is obstructed and moves backward, reducing the distance. When the residue decreases or is removed, the scrubbing support plate 133 springs back to its original position, increasing the distance. This real-time monitoring mechanism enables dynamic adjustment of cleaning parameters, avoiding over-cleaning or under-cleaning. It also improves cleaning efficiency by intelligently adjusting the spray pressure and the rotation speed of the stirring spindle, preventing over-cleaning, reducing energy consumption, minimizing cleaning fluid waste, and extending equipment life.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims, and the specification can be used to interpret the content of the claims.
