Description

Technical Field

[0001] This utility model relates to the field of paint filling technology, and in particular to an integrated machine for precision filtration and filling of water-based fluorocarbon paint products. Background Technology

[0002] Waterborne fluorocarbon paints, with their low VOC emissions, ultra-long weather resistance, and excellent protective performance, have become core coatings in the construction and industrial protection fields. The purity, uniformity, and performance stability of the finished product directly determine the coating effect and service life. Currently, the industry mostly uses dispersed processes for filtration and filling, which have many technical bottlenecks that urgently need to be overcome. With the market's increasing demands for paint quality and stricter environmental policies, traditional dispersed processes can no longer meet the needs of efficient, precise, and low-damage production.

[0003] The above-mentioned and existing related technologies have the following drawbacks: the paint is sensitive to temperature and has weak shear resistance; traditional processes lack precise temperature control design; temperature fluctuations can easily lead to changes in paint viscosity; paint is prone to splashing and generating bubbles during transportation; and traditional stirring devices have excessive shear force, which can not effectively prevent pigment sedimentation and stratification, and may also damage the paint system. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of paint being sensitive to temperature and having weak shear resistance. To address this, we propose an integrated precision filtration and filling machine for water-based fluorocarbon paint products.

[0005] To achieve the above objectives, this application adopts the following technical solution: a precision filtration and filling integrated machine for water-based fluorocarbon paint products, including a mounting base, a screw pump, a filter tank, a transfer cylinder, and a filling rack. The screw pump, filter tank, transfer cylinder, and filling rack are all fixedly installed on the top surface of the mounting base, and a temperature control component is provided outside the filter tank. The temperature control assembly includes a temperature control outer cylinder, which is fixedly sleeved outside the filter tank. The inner wall of the temperature control outer cylinder and the outer wall of the filter tank form a temperature control cavity, which is filled with a temperature control liquid. Several temperature adjustment modules are uniformly fixedly installed on the inner wall of the temperature control outer cylinder. Several temperature-conducting plates that are fixedly connected to each other are fixedly installed on the inner wall of the filter tank. Several external heat dissipation plates are fixedly installed on the outer wall at the bottom of the filter tank. One end of each external heat dissipation plate is fixedly connected to the bottom of the temperature control outer cylinder.

[0006] Preferably, the screw pump is connected to an inlet pipe and an outlet pipe, the bottom of the filter tank is connected to an outlet valve pipe, the inlet pipe is connected to the water-based fluorocarbon paint to be treated, the outlet pipe is connected to the outlet valve pipe, and several precision filter screens are fixedly installed inside the filter tank, with the precision filter screens positioned above the temperature guide plate.

[0007] Preferably, the top of the filter tank is connected to a conveying pipe, the other end of which is fixedly inserted into the transfer cylinder. The end of the conveying pipe extends into the bottom of the transfer cylinder. A low-speed stirring motor is fixedly installed at the bottom of the transfer cylinder. Several low-shear stirring frames are rotatably installed inside the transfer cylinder and are fixedly connected to each other. The output shaft of the low-speed stirring motor rotatably passes through the transfer cylinder and is fixedly connected to the center of the bottom of the low-shear stirring frames.

[0008] Preferably, the bottom of the outer wall of the transfer cylinder is connected to a discharge valve pipe, and the end of the conveying pipe is located above the low-shear mixing frame.

[0009] Preferably, a filling pump is fixedly installed at the top of the filling rack. The filling pump is connected to a suction pipe and a filling pipe. The other end of the suction pipe is fixedly inserted into the transfer cylinder, and the end of the suction pipe extends into the bottom of the transfer cylinder. The other end of the filling pipe passes through the top of the filling rack and into the filling rack.

[0010] Preferably, an installation plate is fixedly installed inside the filling rack, a filling head is fixedly inserted through the center of the installation plate, the end of the filling tube is connected to the top of the filling head, and the end of the extraction tube is positioned above the low-shear mixing frame.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, a temperature control component is incorporated to achieve precise temperature control of the paint material within the filter tank. The temperature-controlled liquid circulates within the temperature-controlled chamber, and the temperature adjustment module can actively heat or cool the liquid. A temperature-conducting plate evenly transfers temperature to the paint material, and an external heat dissipation plate assists in heat dissipation, ensuring that the paint material remains within the optimal temperature range throughout the filtration process. This effectively prevents viscosity changes and paint deterioration caused by temperature fluctuations, thereby improving filtration efficiency and precision.

[0012] In this invention, the filtered paint is directly fed into the transfer cylinder through the conveying pipe. The low-speed stirring motor and low-shear stirring frame inside the transfer cylinder can gently stir the paint, effectively preventing the paint from settling during transfer and waiting for filling. Low-shear stirring prevents settling and ensures the uniformity of the paint. Attached Figure Description

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] Reference Figures 1 to 5 As shown, this utility model provides a technical solution: an integrated precision filtration and filling machine for water-based fluorocarbon paint products, comprising a mounting base plate 1, a screw pump 2, a filter tank 3, a transfer cylinder 4, and a filling rack 5. The screw pump 2, filter tank 3, transfer cylinder 4, and filling rack 5 are all fixedly mounted on the top surface of the mounting base plate 1, making the entire equipment structure compact.

[0017] To address the temperature sensitivity of water-based fluorocarbon paints during filtration, this invention incorporates a temperature control component 6 outside the filter tank 3. This component includes a temperature-controlling outer cylinder 61, which is fixedly fitted around the filter tank 3, forming a sealed temperature-controlling cavity 62. The inner wall of the outer cylinder 61 and the outer wall of the filter tank 3 form the temperature-controlling cavity 62, which is filled with a temperature-controlling liquid, which can be heat-conducting oil or water. Several temperature-regulating modules 63 are uniformly fixedly installed on the inner wall of the outer cylinder 61. These modules can be electric heaters, cooling elements, or heat exchangers, used to precisely control the temperature of the temperature-controlling liquid. Several interconnected temperature-conducting plates 64 are fixedly installed on the inner wall of the filter tank 3. These plates increase the contact area between the inner wall of the filter tank 3 and the paint, and quickly and evenly transfer the temperature of the temperature-controlling liquid to the water-based fluorocarbon paint inside the filter tank 3, ensuring temperature stability during filtration. Several external heat dissipation plates 65 are fixedly installed on the outer wall of the bottom of the filter tank 3. One end of each of these external heat dissipation plates 65 is fixedly connected to the bottom of the temperature control outer cylinder 61, which can assist the temperature control component 6 in heat dissipation, thereby improving the efficiency and stability of temperature control. Through the temperature control component 6, the temperature of the water-based fluorocarbon paint can be precisely controlled at the optimal filtration temperature, avoiding viscosity changes caused by temperature fluctuations, thereby improving filtration efficiency and paint quality.

[0018] The screw pump 2 is connected to an inlet pipe 21 and an outlet pipe 22. The screw pump 2 delivers the water-based fluorocarbon paint to the filter tank 3 and pushes it into the transfer cylinder 4. The inlet pipe 21 connects to the water-based fluorocarbon paint to be treated, responsible for extracting the untreated paint from the storage tank. The outlet pipe 22 connects to the outlet valve 31 at the bottom of the filter tank 3, pumping the paint into the filter tank 3 for filtration. The screw pump 2 has the advantages of stable delivery, low shear force, and no damage to the paint, making it particularly suitable for conveying viscous and shear-sensitive water-based fluorocarbon paint. Several precision filter plates 32 are fixedly installed inside the filter tank 3. These precision filter plates 32 are positioned above the temperature-conducting plate 64 and are used for multi-stage precision filtration of the paint, removing impurities and particles to ensure the purity of the paint. The pore size of the precision filter plates 32 can be selected according to the particle size requirements of the paint to achieve the best filtration effect.

[0019] like Figure 6As shown, a feed pipe 33 is connected to the top of the filter tank 3, and the other end of the feed pipe 33 is fixedly inserted into the transfer cylinder 4. The end of the feed pipe 33 extends deep into the bottom of the transfer cylinder 4 to ensure that the filtered paint can smoothly enter the transfer cylinder 4, reducing splashing and the generation of bubbles. A low-speed stirring motor 41 is fixedly installed at the bottom of the transfer cylinder 4, which drives the stirring device. Several low-shear stirring frames 42 are rotatably installed inside the transfer cylinder 4 and fixedly connected to each other. The output shaft of the low-speed stirring motor 41 rotatably passes through the transfer cylinder 4 and is fixedly connected to the center of the bottom of the low-shear stirring frames 42. The low-shear stirring frames 42 are designed to gently stir the paint, preventing the paint from settling or separating during transfer and waiting for filling, maintaining the uniformity and stability of the paint, and avoiding excessive shearing of the paint, which would affect its performance. The end of the feed pipe 33 is positioned above the low-shear stirring frames 42, so that the paint can be directly covered by the stirring action of the low-shear stirring frames 42 after entering the transfer cylinder 4, further ensuring the uniform mixing of the paint.

[0020] The bottom of the outer wall of the transfer cylinder 4 is connected to a discharge valve pipe 43, which is used to discharge the paint in the transfer cylinder 4 when needed, such as for cleaning or changing the type of paint.

[0021] A filling pump 51 is fixedly installed at the top of the filling rack 5, and the filling pump 51 is connected to a suction pipe 52 and a filling pipe 53. The other end of the suction pipe 52 is fixedly inserted into the transfer cylinder 4, and the end of the suction pipe 52 extends to the bottom of the transfer cylinder 4 to ensure that the paint in the transfer cylinder 4 can be fully extracted. The other end of the filling pipe 53 passes through the top of the filling rack 5 and into the filling rack 5, and is used to transport the paint to the filling head 55. An installation plate 54 is fixedly installed inside the filling rack 5, and the filling head 55 is fixedly inserted through the center of the installation plate 54. The end of the filling pipe 53 is connected to the top of the filling head 55. The filling head 55 is the part that directly contacts the filling container, and its design can be adjusted according to different filling containers to achieve accurate and drip-free filling. The end of the suction pipe 52 is positioned above the low-shear stirring frame 42, so that during the filling process, the paint can still be stirred by the low-shear stirring frame 42 before being extracted, further ensuring the uniformity of the filled paint.

[0022] It should be noted that the specific structure of the filling head 55 and the connection and control of the electronic components in this utility model are existing mature technologies and are not the key technical points of this utility model, so they will not be elaborated here.

[0023] The workflow is as follows: The water-based fluorocarbon paint to be processed is drawn by the screw pump 2 through the inlet pipe 21 and enters the filter tank 3 through the delivery pipe 22. In the filter tank 3, the paint undergoes multi-stage filtration through the precision filter screen 32 under the precise temperature control of the temperature control component 6 to remove impurities. The filtered paint enters the transfer cylinder 4 through the delivery pipe 33. In the transfer cylinder 4, the low-speed stirring motor 41 drives the low-shear stirring frame 42 to gently stir the paint and prevent sedimentation. When filling is required, the filling pump 51 draws paint from the transfer cylinder 4 through the extraction pipe 52 and delivers it to the filling head 55 in the filling rack 5 through the filling pipe 53, finally completing the precise filling of the container.

[0024] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
