Description

Technical Field

[0001] This application relates to the technical field of electrophoretic paint storage tanks, and in particular to an anti-settlement type electrophoretic paint storage tank. Background Technology

[0002] As a core technology in the field of surface treatment, the quality of electrophoretic coating is highly dependent on the stability of the electrophoretic paint. However, as a complex colloidal system composed of resin, pigment, additives and solvent, electrophoretic paint is prone to particle sedimentation, pigment agglomeration and resin phase separation due to gravity during static storage, which leads to the deterioration of paint performance and causes defects such as uneven coating thickness, flow marks and orange peel.

[0003] The existing announcement number CN219506739U, entitled "A Paint Storage Tank," includes a storage tank body with a drive motor mounted on its upper end. The output end of the drive motor is connected to a stirring mechanism, which includes a transmission component connected to the output end of the drive motor. The transmission component is connected to an upper stirring element and a lower stirring element, which rotate in opposite directions. Cleaning mechanisms that fit against the inner wall of the storage tank body are also provided on both sides of the upper stirring element. The transmission component used in this invention can drive the upper and lower stirring elements to move synchronously, thereby enabling more thorough and effective stirring of the paint in the tank. Compared with the single stirring direction of the comparative case, this device stirs more thoroughly and evenly. At the same time, the upper stirring element, lower stirring element, and cleaning mechanism in this device have a simple structure, small overall area, and will not be contaminated with excessive paint.

[0004] Regarding the aforementioned technologies, the inventors discovered that in order to prevent the electrophoretic paint inside the storage tank from settling, the storage tank uses a low-speed paddle agitator to increase the bottom flow rate and suppress particle settling. However, such devices have the problem that the paddles are in direct contact with the paint liquid, which can easily introduce shear heat, leading to a local temperature increase and accelerating the resin crosslinking reaction. Utility Model Content

[0005] In order to overcome the problem that existing storage tanks use low-speed paddle agitation to suppress particle settling by increasing the bottom flow velocity, but such devices have the problem that the paddles are in direct contact with the paint liquid, which can easily introduce shear heat, leading to local temperature rise and accelerating the resin crosslinking reaction, this application provides an anti-settling electrophoretic paint storage tank.

[0006] The anti-settlement electrophoretic paint storage tank provided in this application adopts the following technical solution: An anti-settling electrophoretic paint storage tank includes a paint storage component and a support component. The paint storage component includes a tank body. A feeding pipe is vertically connected and fixed to the upper part of the outer circumference of the tank body, and a valve is connected and fixed to the feeding pipe. Multiple air rods are horizontally fixed inside the tank body, and an air inlet pipe is horizontally connected and fixed to the end of the tank body at the air inlet port. Support components are provided on both sides of the bottom of the outer circumference of the tank body. The support component includes a slide bar and a slide frame. The slide bar is horizontally set below the tank body, and a slide frame is horizontally slidably assembled above the slide bar. A support ring is vertically fixed on the top surface of the slide frame and fixed to the outer circumference of the tank body.

[0007] By adopting the above technical solution, the electrophoretic paint is added through the feeding pipe on the outer wall of the tank during use. To prevent the electrophoretic paint inside the tank from settling, the valve on the feeding pipe is opened, and the air inlet pipe is activated to bring external air into the tank. The air enters multiple air rods through the air inlet pipe, and then the air is ejected from multiple air ports on the air rods into the electrophoretic paint inside the tank. The air pulse generates a periodic microbubble flow at the bottom of the tank, which prolongs the suspension time of the pigment particles at the bottom. Then, the air forms bubbles in the electrophoretic paint, and the bubbles burst upward, causing the electrophoretic paint to flow. The air is then discharged through the feeding pipe, so the electrophoretic paint inside the tank will not settle. At the same time, low-speed blade stirring is not used, which avoids the blades directly contacting the paint liquid and introducing shear heat, which would cause local temperature rise and accelerate the resin cross-linking reaction, thus improving the good anti-settling properties of the electrophoretic paint inside the tank.

[0008] Optionally, a discharge pipe is fixedly connected to the bottom of the outer circumference of the tank, and a water pump is fixedly connected to the discharge pipe.

[0009] By adopting the above technical solution, a water pump is fixedly connected to the discharge pipe on the outer circumference of the tank, and the water pump drives the electrophoretic paint inside the tank to flow and discharge.

[0010] Optionally, an air pump is connected and fixed to the air intake pipe, and a screw cap is connected and fixed to the end of the air intake pipe.

[0011] By adopting the above technical solution, the air pump connected to the air intake pipe is used to draw air into the interior of the tank, and the screw cap at the end of the air intake pipe facilitates the later assembly of the air filter component.

[0012] Optionally, a filter cartridge is threaded onto the screw cap, the interior of the filter cartridge is filled with filter cotton, and a mesh is fixed to the other end of the filter cartridge.

[0013] By adopting the above technical solution, a filter cartridge is assembled on the screw cap. Air is filtered through the mesh to remove impurities. When air enters the filter cartridge, the dust in the air is filtered out by the filter cotton, effectively removing dust and impurities from the air and ensuring the cleanliness of the air.

[0014] Optionally, a support is vertically fixed to the bottom surface of the slide bar, and multiple fixing screws are vertically mounted through the bottom surface of the support, and the multiple fixing screws are used to fix the slide bar.

[0015] By adopting the above technical solution, the vertically fixed support on the bottom surface of the slide bar is fixed to the installation point by multiple fixing screws, ensuring the installation stability of the slide bar.

[0016] Optionally, a drive motor is vertically fixed to one end of the slide bar, and a dial is horizontally fixed to the output end of the drive motor, with multiple dial blades evenly fixed on the outer circumference of the dial.

[0017] By adopting the above technical solution, in order to increase the anti-settling properties of the electrophoretic paint inside the tank, the drive motor on the slide bar is started, the drive motor drives the dial wheel to rotate, and the multiple paddles on the rotating dial wheel press against and move the tank body to make it shake.

[0018] Optionally, a top wheel is vertically mounted on the other end of the sliding frame, and the top wheel is rotatably connected to the sliding frame.

[0019] By adopting the above technical solution, multiple paddles on the rotating wheel press against the top wheel on the sliding frame, pushing the sliding frame to slide horizontally on the slide bar, and the lateral movement drives the tank to slide.

[0020] Optionally, a spring is horizontally fixed to the other end of the slider, and the other end of the spring is fixed to the slide frame.

[0021] By adopting the above technical solution, the sliding frame slides horizontally on the slide bar, compressing the spring deformation. When the multiple paddles on the dial wheel are no longer pressing against the top wheel on the sliding frame, the spring deformation force pushes the sliding frame to slide back on the slide bar, thereby reciprocating the sliding frame sliding on the slide bar, shaking the electrophoretic paint in the tank.

[0022] In summary, this application includes at least one of the following beneficial technical effects: During use, the electrophoretic paint is added through the feeding pipe on the outer wall of the tank. To prevent the electrophoretic paint inside the tank from settling, the valve on the feeding pipe is opened, and the air inlet pipe is activated to bring external air into the tank. The air enters multiple air rods through the air inlet pipe, and then the air is ejected from multiple air ports on the multiple air rods into the electrophoretic paint inside the tank. The air pulse generates a periodic microbubble flow at the bottom of the tank, which prolongs the suspension time of the pigment particles at the bottom. Then, the air forms bubbles in the electrophoretic paint, and the bubbles burst upward, causing the electrophoretic paint to flow. The air is discharged through the feeding pipe, so the electrophoretic paint inside the tank will not settle. At the same time, low-speed blade stirring is not used, which avoids the blades from directly contacting the paint liquid and introducing shear heat, which would lead to a local temperature increase, accelerate the resin cross-linking reaction, and improve the good anti-settling properties of the electrophoretic paint inside the tank.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses an anti-settling electrophoretic paint storage tank. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A type of anti-settling electrophoretic paint storage tank includes a paint storage component 1 and a support component 2. The paint storage component 1 includes a tank body 11. A feeding pipe 12 is vertically connected and fixed to the upper part of the outer circumference of the tank body 11, and a valve is connected and fixed to the feeding pipe 12. Multiple air rods 15 are horizontally fixed through the inside of the tank body 11, and an air inlet pipe 16 is horizontally connected and fixed to the end of the tank body 11 at the air inlet port. Support components 2 are provided on both sides of the bottom of the outer circumference of the tank body 11. The support component 2 includes a slide bar 21 and a sliding frame 23. The slide bar 21 is horizontally arranged below the tank body 11, and the sliding frame 23 is horizontally slidably assembled above the slide bar 21. A support ring 24 is vertically fixed on the top surface of the sliding frame 23, and the support ring 24 is fixed to the outer circumference of the tank body 11.

[0027] By adopting the above technical solution, the electrophoretic paint is added through the feeding pipe 12 on the outer wall of the tank 11. To prevent the electrophoretic paint inside the tank 11 from settling, the valve on the feeding pipe 12 is opened, and the air inlet pipe 16 is activated to bring external air into the tank 11. The air enters multiple air rods 15 through the air inlet pipe 16, and then the air is sprayed out from multiple air ports on the multiple air rods 15 into the electrophoretic paint inside the tank 11. The air pulse generates a periodic microbubble flow at the bottom of the tank 11, which prolongs the suspension time of the pigment particles at the bottom. Then, the air forms bubbles in the electrophoretic paint, and the bubbles burst upward, causing the electrophoretic paint to flow. The air is discharged through the feeding pipe 12, so the electrophoretic paint inside the tank 11 will not settle. At the same time, low-speed blade stirring is not used, which avoids the blades from directly contacting the paint liquid and introducing shear heat, resulting in local temperature rise, accelerating the resin cross-linking reaction, and improving the good anti-settling properties of the electrophoretic paint inside the tank 11.

[0028] Reference Figure 3 A discharge pipe 13 is fixedly connected to the bottom of the outer circumference of the tank 11, and a water pump 14 is fixedly connected to the discharge pipe 13. The water pump 14 is fixedly connected to the discharge pipe 13 on the outer circumference of the tank 11, and the water pump 14 drives the electrophoretic paint inside the tank 11 to flow and discharge.

[0029] Reference Figure 4 An air pump 161 is connected and fixed to the air intake pipe 16, and a screw cap 17 is connected and fixed to the end of the air intake pipe 16. The air pump 161 connected to the air intake pipe 16 is used to draw air into the interior of the tank 11, and the screw cap 17 at the end of the air intake pipe 16 facilitates the later assembly of the air filter components. A filter cartridge 18 is threaded onto the screw cap 17, and the interior of the filter cartridge 18 is filled with filter cotton 19, and a mesh 181 is fixed to the other end of the filter cartridge 18. With the filter cartridge 18 threaded onto the screw cap 17, air is filtered through the mesh 181 to remove impurities, and as air enters the filter cartridge 18, dust in the air is filtered and removed by the filter cotton 19, effectively removing dust and impurities from the air and ensuring the cleanliness of the air.

[0030] Reference Figure 5A support 22 is vertically fixed to the bottom surface of the slide bar 21, and multiple fixing screws 221 are vertically mounted through the bottom surface of the support 22 for fixing the slide bar 21. The support 22 vertically fixed to the bottom surface of the slide bar 21 is fixed to the installation point by the multiple fixing screws 221, ensuring the installation stability of the slide bar 21. A drive motor 27 is vertically fixed to one end of the slide bar 21, and a dial wheel 28 is horizontally fixed to the output end of the drive motor 27. Multiple pawls are evenly fixed to the outer circumference of the dial wheel 28. To increase the anti-settling properties of the electrophoretic paint inside the tank 11, the drive motor 27 on the slide bar 21 is started. The drive motor 27 drives the dial wheel 28 to rotate. The multiple pawls on the rotating dial wheel 28 press against and agitate the tank 11, causing it to shake. A top wheel 25 is vertically provided at the other end of the sliding frame 23, and the top wheel 25 is rotatably connected to the sliding frame 23. The rotating dial 28 has multiple paddles that press against the top wheel 25 on the sliding frame 23, pushing the sliding frame 23 to slide horizontally on the slide bar 21, thus causing the can 11 to slide laterally. A spring 26 is horizontally fixed to the other end of the slide bar 21, and the other end of the spring 26 is fixed to the sliding frame 23. As the sliding frame 23 slides horizontally on the slide bar 21, it compresses and deforms the spring 26. When the paddles on the dial 28 are no longer pressing against the top wheel 25 on the sliding frame 23, the deformation force of the spring 26 pushes the sliding frame 23 back to its original position on the slide bar 21, thus reciprocating and causing the sliding frame 23 to slide on the slide bar 21, shaking the electrophoretic paint in the can 11.

[0031] The implementation principle of an anti-settling electrophoretic paint storage tank according to an embodiment of this application is as follows: During use, electrophoretic paint is added through the feeding pipe 12 on the outer wall of the tank 11. To prevent the electrophoretic paint inside the tank 11 from settling, the valve on the feeding pipe 12 is opened. The air pump 161 connected to the air inlet pipe 16 is used to draw air into the tank 11. The air is filtered through the mesh 181 to remove impurities and enters the filter cartridge 18. Dust in the air is filtered out by the filter cotton 19, effectively removing dust and impurities from the air. The air inlet pipe 16 is activated to bring external air into the tank 11. The air enters multiple air rods 15 through the air inlet pipe 16, and then the air is ejected from multiple air ports on the multiple air rods 15 into the electrophoretic paint inside the tank 11. The air pulse generates a periodic microbubble flow at the bottom of the tank 11, prolonging the suspension time of the pigment particles at the bottom. Then, air forms bubbles in the electrophoretic paint, and the bubbles burst upwards, causing the electrophoretic paint to settle. Air flows and is discharged through the feeding pipe 12. To increase the anti-settling properties of the electrophoretic paint inside the tank 11, the drive motor 27 on the slide bar 21 is activated. The drive motor 27 drives the dial wheel 28 to rotate. The multiple blades on the rotating dial wheel 28 press against the top wheel 25 on the sliding frame 23, pushing the sliding frame 23 to slide horizontally on the slide bar 21. This lateral movement causes the tank 11 to slide. The sliding frame 23 slides horizontally on the slide bar 21. When the spring 26 is compressed and deformed, when the multiple paddles on the dial wheel 28 are no longer pressing against the top wheel 25 on the sliding frame 23, the deformation force of the spring 26 pushes the sliding frame 23 to slide back on the slide bar 21, thereby reciprocatingly driving the sliding frame 23 to slide on the slide bar 21, shaking the electrophoretic paint in the tank 11. A water pump 14 is connected and fixed on the discharge pipe 13 on the outer circumference of the tank 11, and the water pump 14 drives the electrophoretic paint inside the tank 11 to flow and discharge.

[0032] 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.
