Description

Technical Field

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

[0002] In the industrial production process, debubble tanks are widely used in the fields of chemistry, pharmaceuticals, food processing, and electronic manufacturing to remove bubbles or tiny particles from liquids to ensure product quality and process stability. However, the tank wall of the debubble tank is prone to residues, such as bubble residues after solidification, sticky substances, chemical deposits, etc. If these residues are not cleaned in time, they will affect the subsequent production quality and may cause equipment operation efficiency to decrease or even malfunction.

[0003] In the production process of chip multilayer ceramic capacitors, the internal electrodes and dielectric layers are made of metal slurries with high solid content (such as silver slurry, nickel slurry) or ceramic slurries (such as BaTiO3 dielectric slurry). These slurries are easily mixed with bubbles during the stirring, grinding, and transportation processes. The defoaming tank is used to remove bubbles from the slurry through a combination of negative pressure vacuum and stirring.

[0004] After the traditional defoaming tank is discharged, the porcelain slurry residue on the tank wall has dried and hardened. This dry slurry residue needs to be soaked in anhydrous ethanol and scraped to dissolve, and the operator can only use a copper wire brush to scrub it. When cleaning manually, the operator needs to wear a gas mask, bend over and use a copper wire brush to bring up the anhydrous ethanol at the bottom of the tank to scrape the tank wall. This is not only inefficient, but also poses a great threat to the personal safety of the operator. There is a risk of lumbar muscle strain due to long-term bending, and there is a risk of respiratory diseases caused by inhalation of aerosols due to the volatilization of anhydrous ethanol.

[0059] In view of the technical problems in the background technology, the present application provides an automatic cleaning device for a defoaming tank, which can realize automatic cleaning of the tank wall of the defoaming tank.

[0060] like Figure 1-6 As shown, in one embodiment, the automatic cleaning device 100 of the defoaming tank includes a scrubbing mechanism 10, which is used to be detachably mounted on the stirring main shaft 210 of the defoaming tank 200. The stirring main shaft 210 is used to stir the slurry in the defoaming tank 200 by rotating and driving the stirring paddle 211 thereon during the defoaming process. During the defoaming process, the scrubbing mechanism 10 does not need to be installed on the defoaming tank 200, but is detachably mounted on the stirring main shaft 210 after the defoaming process is completed to scrub the tank wall.

[0061] Specifically, Figure 2 As shown, the brushing mechanism 10 includes a connecting component 11, a hanging arm 12 and a brushing component 13, wherein the connecting component 11 is used to be fixed on the stirring main shaft 210, one end of the hanging arm 12 is connected to the connecting component 210, and the brushing component 13 is connected to the other end of the hanging arm 12, and the brushing component 13 is used to clean the tank wall of the defoaming tank.

[0062] Preferably, the connecting component 11 is also detachably fixed on the stirring main shaft 210, and the brushing component 13 brushes and cleans the tank wall through the brushing elements arranged thereon. Specifically, the brushing elements can be brush strips made of metal or other materials, for example, copper wire brush strips.

[0063] The automatic cleaning device of the debubble tank in the embodiment of the present application realizes automatic cleaning of the tank wall of the debubble tank by fixing the brushing mechanism on the stirring main shaft of the debubble tank; since the brushing mechanism can be detachably installed on the stirring main shaft, it can be quickly installed when in use and can be easily disassembled when not in use, which is convenient for replacement or maintenance; the detachable connection structure is adopted, so that the hanging arm can be quickly assembled or disassembled with the connecting component, thereby improving the versatility of the equipment and being suitable for debubble tanks of different specifications; since the brushing component directly acts on the tank wall, it can effectively scrape off stubborn residues to avoid the residues affecting subsequent production; the brushing component is fixed on the hanging arm and can rotate with the stirring main shaft to achieve uniform and full-coverage brushing, avoid cleaning dead corners, and improve the cleaning effect.

[0064] In an optional embodiment, if Figure 3-Figure 5 As shown, the brush assembly 10 includes an elastic support seat 131, a brush support plate 133 and a brush element 134. The brush element 134 is fixed on the brush support plate 133 and is used to contact the tank wall of the defoaming tank 200 and scrape the residue.

[0065] In this embodiment, the elastic support seat 131 is fixedly connected to the hanging arm 12, and the brush support plate 133 is connected to the elastic support seat 131 through an elastic connection structure, wherein the elastic connection structure enables the brush support plate 133 to approach or move away from the elastic support seat 131 along the radial direction of the defoaming tank 200.

[0066] The automatic cleaning device for the defoaming tank of the present embodiment has a scrubbing support plate connected to the elastic support seat by an elastic connection structure. When there are local unevenness, curvature changes or different thicknesses of residues on the tank wall, the scrubbing support plate can automatically adjust its position to ensure that the scrubbing element always fits tightly against the tank wall and enhances the scraping and cleaning ability; it can adapt to slight deformations of different tank walls and improve the cleaning quality.

[0067] Since the scrubbing support plate has radial elastic movement capability, when the scrubbing element contacts the tank wall, the elastic connection structure can automatically adjust the contact pressure to ensure appropriate scraping force, which neither damages the tank wall nor can effectively clean it. This structure avoids excessive squeezing or excessive relaxation, thereby extending the service life of the scrubbing component and reducing the maintenance cost of the equipment during long-term operation.

[0068] Preferably, Figure 3-Figure 5As shown, the elastic connection structure includes an elastic support unit and a guide unit. Specifically, the elastic support unit includes a plurality of springs 132, and the plurality of springs 132 are connected between the elastic support seat 131 and the scrubbing support plate 133. The spring 132 can be directly fixedly connected to the surface of the elastic support seat 131 and the scrubbing support plate 133. In a preferred example, for ease of setting, one or all of the elastic support seat 131 and the scrubbing support plate 133 are provided with a receiving hole for receiving the spring 132.

[0069] The guide unit includes a guide post 135 and a guide hole 136. The guide post 135 is disposed on one of the elastic support seat 131 and the brush support plate 133, and the guide hole 136 is disposed on the other. The guide post 135 extends into the guide hole 136 to limit the movement direction of the brush support plate 133. Figures 3 to 5 In the embodiment of the present invention, the guide column 135 is arranged on the scrubbing support plate 133, and the guide hole 136 is arranged on the elastic support seat 131 as an example for description.

[0070] In order to limit the movement of the scrubbing support plate 133 so that it does not separate from the elastic support seat 131, in one embodiment, Figure 4-5 As shown, the brushing assembly also includes a limiting unit, which includes a limiting hole 137 and a limiting member 138, wherein the limiting hole 137 is arranged on the elastic support seat 131, the limiting member 138 partially passes through the limiting hole 137 and is fixedly connected to the brushing support plate 133, and the limiting member 138 can move forward and backward relative to the limiting hole 137; the part of the limiting member 138 that does not pass through the limiting hole 137 has a limiting portion with a diameter larger than the limiting hole 137, so that the limiting member 138 will not completely pass through the limiting hole 137.

[0071] Preferably, 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, wherein the threaded section 1383 is threadedly connected to the threaded hole 1331 set on the brush support plate 133; the diameter of the bolt head 1381 is larger than the limiting hole 137, and is located on the side of the limiting hole 137 away from the brush 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 forward and backward relative to the limiting hole 137.

[0072] In this embodiment, when the spring 132 supports the scrubbing support plate 133 away from the elastic support seat 131 and drives the limit piece 138 to move forward until the bolt head 1381 abuts against the elastic support seat 131, the scrubbing support plate 133 is limited to the farthest position from the elastic support seat 131 and cannot move further away, so that the scrubbing support plate 133 will not fall off.

[0073] In a specific embodiment, Figure 3-5 As shown, the connecting assembly 11 includes a first fixing member 111 and a second fixing member 112, wherein the first fixing member 111 has a first arc-shaped clamping groove 1111; and the second fixing member 112 is provided with a second arc-shaped clamping groove 1121 matching 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 defoaming tank stirring main shaft 210. Preferably, the first arc-shaped clamping groove 1111 and the second arc-shaped clamping groove 1121 are both semicircular.

[0074] In this embodiment, the first fixing member 111 and the second fixing member 112 can be fixed to each other by fastening connection, so as to be fixed to the stirring main shaft 210. By fastening the first fixing member 111 and the second fixing member 112, or disassembling and separating them, the brushing mechanism 10 can be fixed to the stirring main shaft 210, or be removed from the stirring main shaft 210.

[0075] In a specific embodiment, Figure 3-5 As shown, the detachable connection structure connecting the connecting component 11 and the hanging arm 12 includes a slot 1112 and a plug-in portion 121, the slot 1112 is arranged on the first fixing member 111; the plug-in portion 121 matches the slot 1112 and is arranged at the end of the hanging arm 12; the hanging arm 12 is inserted into the slot 1112 through the plug-in portion 121, thereby being fixedly connected with the connecting component 11.

[0076] In one embodiment, if Figure 1-Figure 7 As shown, the automatic cleaning device 100 for the defoaming tank further includes a spray system, which includes a pneumatic diaphragm pump 21 and a spray pipe 22. The pneumatic diaphragm pump 21 is used to provide cleaning liquid to the spray pipe. Specifically, the spray pipe 22 is connected to the pneumatic diaphragm pump 21 through a delivery pipe 23; the spray pipe 22 is arranged in a ring shape along the top of the defoaming tank 200, and is used to spray the cleaning liquid into the defoaming tank 200.

[0077] like Figure 6 and Figure 7 As shown, the spray pipe 22 is provided with a plurality of 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 to be tilted downward so that the cleaning liquid flows downward along the tank wall and will not be splashed into the tank body.

[0078] Preferably, the cleaning liquid is anhydrous ethanol, such as Figure 1 As shown, the pneumatic diaphragm pump 21 extracts the anhydrous ethanol in the cleaning liquid tank 26 and delivers it to the spray pipe 22. In this embodiment, the 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.

[0079] like Figure 1 and Figure 6 As shown, in one embodiment, the spray system also 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 from the main liquid supply pipe 24 and connected to the spray pipe 22, and the branch pipe 25 is symmetrically arranged along the top of the defoaming tank 200.

[0080] In a preferred embodiment, 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.

[0081] The first height position is higher than the second height position, and both the first height position and the second height position are located at the lower half of the spray pipe 22 . The inclination of the first group of spray holes 221 is greater than that of the second group of spray holes 222 .

[0082] In this embodiment, two groups of spray holes at different heights are arranged in a staggered and uniform manner, so that the spraying effect can be made more uniform.

[0083] In a preferred embodiment, in order to achieve better control over the flow rate of the cleaning liquid, the automatic cleaning device 100 for removing the foam tank also includes a controller (not shown) and a distance sensor (not shown). The controller is connected to the pneumatic diaphragm pump 21, the distance sensor and the driving motor signal of the stirring spindle 210. The distance sensor is arranged on the elastic support seat 131 and is used to detect the interval distance between the elastic support seat 131 and the brush support plate 133 during use.

[0084] The controller is used to receive the interval distance signal sent by the distance sensor, and control the spray pressure of the pneumatic diaphragm pump 21 and the rotational speed of the stirring spindle 210 according to the interval distance; wherein, the larger the interval distance, the smaller the spray pressure output by the pneumatic diaphragm pump 21 controlled by the controller, and the smaller the rotational speed of the stirring spindle 210 controlled; the smaller the interval distance, the larger the spray pressure output by the pneumatic diaphragm pump 21 controlled by the controller, and the larger the rotational speed of the stirring spindle controlled.

[0085] Specifically, the distance sensor can be a non-contact displacement sensor, which is arranged on the elastic support seat 131 and faces the brush support plate 133, so as to detect the distance between the two and preferentially transmit the distance signal to the controller through a wireless (Bluetooth) sensor.

[0086] In this embodiment, by detecting the interval distance between the elastic support seat 131 and the scrubbing support plate 133 through a distance sensor, the fit of the scrubbing assembly to the tank wall can be monitored in real time. When the residue on the tank wall is thicker, the scrubbing support plate 133 is blocked and moves backward, and the interval distance is reduced; when the residue is reduced or cleared, the scrubbing support plate 133 rebounds and resets, and the interval distance increases; this real-time monitoring mechanism makes it possible to dynamically adjust the cleaning parameters to avoid excessive or insufficient cleaning; it can also improve the cleaning efficiency by intelligently adjusting the spray pressure and the stirring spindle speed; avoid excessive cleaning, reduce energy consumption, reduce the waste of cleaning fluid, and extend the life of the equipment.

[0087] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0088] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims, and the description may be used to interpret the contents of the claims.
