Description

Technical Field

[0001] This utility model relates to the field of filtration of fluorocarbon coatings, and more particularly to a filtration device for high-performance fluorocarbon coatings with UV resistance. Background Technology

[0002] Fluorocarbon coatings refer to coatings with fluororesin as the main film-forming substance. They are also known as fluorocarbon paints, fluorocoatings, fluororesin coatings, etc. Among various coatings, fluororesin coatings have particularly superior properties due to the high electronegativity of the introduced fluorine element and the strong carbon-fluorine bond energy. These properties include weather resistance, heat resistance, low-temperature resistance, and chemical resistance. In addition, they have unique non-stick and low friction properties. In the production process of fluorocarbon coatings, the mixed coating needs to be filtered to meet production requirements. Therefore, a filtration device for fluorocarbon coating production is needed.

[0003] While traditional filtration equipment can remove impurities from coatings to some extent, when filtering fluorocarbon coatings, the fluorocarbon coating relies solely on gravity for flow, resulting in low pressure and slow flow velocity. This makes it difficult to completely remove fine particles from the coating, leading to low filtration efficiency and affecting the filtration effect. Therefore, a high-performance UV-resistant fluorocarbon coating filtration device is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a filtration device for UV-resistant high-performance fluorocarbon coating, comprising a support frame, a top tank fixedly connected to the inner wall of the support frame, a bottom tank fixedly connected to the bottom of the top tank, a filtration mechanism disposed inside the bottom tank, a discharge pipe fixedly connected to the right side of the bottom tank, a pressure filter mechanism disposed at the top of the support frame, the pressure filter mechanism comprising a stepper motor fixedly connected to the top of the support frame, a circular plate fixedly connected to the front side of the output shaft of the stepper motor, a connecting rod hinged to the front side of the circular plate, a vertical rod connected to the end of the connecting rod away from the circular plate, the vertical rod slidably connected to the inner wall of the top tank, a pressure plate fixedly connected to the bottom of the vertical rod, the pressure plate slidably connected to the inner wall of the top tank, a second one-way valve disposed on the surface of the pressure plate, a feed pipe fixedly connected to the left side of the top tank, and a first one-way valve disposed on the surface of the feed pipe.

[0011] The pressure plate has a protrusion on its top.

[0012] As a further description of the above technical solution:

[0013] The filtration mechanism includes a fixing plate, which is fixedly connected to the inner wall of the bottom tank, and a placement groove is provided on the top of the fixing plate.

[0014] As a further description of the above technical solution:

[0015] The filtration mechanism also includes a filter box, which is disposed inside the placement slot. A sealing gasket is provided between the filter box and the placement slot, and a screen is provided at the bottom of the filter box.

[0016] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the stepper motor drives the circular plate to rotate, and then the connecting rod drives the vertical rod to make linear reciprocating motion in the vertical direction, which drives the pressure plate to move up and down, gradually pressing the fluorocarbon coating from the top tank into the bottom tank for filtration. This increases the conveying pressure and filtration speed, thereby reducing filtration residue and improving filtration efficiency.

[0022] 2. In this utility model, by setting an elastic sheet at the bottom of the fixing ring, the elastic sheet will deform when subjected to external force and apply a downward elastic force to the filter box, which will press the sealing gasket at the bottom of the filter box more tightly in the placement groove, thereby improving the sealing effect and thus improving the filtration efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 One embodiment of this utility model is a filtration device for UV-resistant high-performance fluorocarbon coating, including a support frame 1, a top tank 2 fixedly connected to the inner wall of the support frame 1, a bottom tank 3 fixedly connected to the bottom of the top tank 2, a sealing ring between the bottom of the top tank 2 and the top of the bottom tank 3, and a filter press mechanism 4 provided on the top of the support frame 1.

[0031] Reference Figure 1 , Figure 2The filter press mechanism 4 includes a stepper motor 5, which has high control precision and can accurately control the rotation angle of its output shaft. The stepper motor 5 is fixedly connected to the top of the support frame 1. A circular plate 6 is fixedly connected to the front side of the output shaft of the stepper motor 5. A connecting rod 7 is hinged to the front side of the circular plate 6 in an inclined state. The connecting rod 7 is hinged at the non-center of the front side of the circular plate 6. A vertical rod 8 is connected to the end of the connecting rod 7 away from the circular plate 6. When the stepper motor 5 works and causes the circular plate 6 to rotate, the vertical rod 8 makes a linear reciprocating motion in the vertical direction through the transmission of the connecting rod 7. The vertical rod 8 is slidably connected to the inner wall of the top tank 2. The displacement direction of the vertical rod 8 is up and down. A horizontally arranged pressure plate 9 is fixedly connected to the bottom of the vertical rod 8. A protrusion is provided on the top of the pressure plate 9. The protrusion of the pressure plate 9 enhances the uniformity of the coating extrusion.

[0032] Reference Figure 1 , Figure 2 The pressure plate 9 is slidably connected to the inner wall of the top tank 2. The pressure plate 9 slides up and down. A one-way valve 12 is provided on the surface of the pressure plate 9, so that the fluorocarbon coating above the pressure plate 9 in the top tank 2 can only enter the bottom tank 3 below the pressure plate 9 in one direction, waiting for subsequent filtration. A feed pipe 10 for inputting the fluorocarbon coating to be filtered is fixedly connected to the left side of the top tank 2. A one-way valve 11 is provided on the surface of the feed pipe 10, so that the fluorocarbon coating inside the feed pipe 10 can only enter the pressure plate 9 inside the top tank 2 in one direction. A filtration mechanism 14 is provided inside the bottom tank 3. A discharge pipe 22 for discharging the filtered fluorocarbon coating is fixedly connected to the right side of the bottom tank 3.

[0033] Reference Figures 2-4 The filtration mechanism 14 includes a fixing plate 13, which is fixedly connected to the inner wall of the bottom tank 3. The top of the fixing plate 13 is provided with a placement groove 15 that matches the shape of the filter box 16. The filtration mechanism 14 also includes a filter box 16, which is disposed inside the placement groove 15. A sealing gasket 18 is provided between the filter box 16 and the placement groove 15. A screen 17 is provided at the bottom of the filter box 16.

[0034] Reference Figure 3 , Figure 4The filter mechanism 14 also includes a fixing ring 19, the bottom of which contacts the top of the filter box 16. The fixing ring 19 is fixedly connected to the fixing plate 13 by fixing bolts 20. The filter mechanism 14 also includes an elastic sheet 21 with its own elasticity. The elastic sheet 21 is located at the bottom of the fixing ring 19 and contacts the top of the filter box 16. The elastic sheet 21 is set in an arc shape. When the elastic sheet 21 is not subjected to external force, it is a naturally extended arc shape. When the elastic sheet 21 is subjected to external force, it will deform and bend, thereby applying a downward elastic force to the filter box 16, thereby pressing the sealing gasket 18 at the bottom of the filter box 16 more tightly in the placement groove 15, improving the filtration effect of the fluorocarbon coating.

[0035] Working principle: During use, the UV-resistant high-performance fluorocarbon coating to be filtered is fed into the pressure plate 9 inside the top tank 2 through the feed pipe 10. The stepper motor 5 is started, and its output shaft drives the circular plate 6 to rotate. Since the connecting rod 7 is hinged at the non-center of the front side of the circular plate 6, the rotation of the circular plate 6 causes the connecting rod 7 to push the vertical rod 8 to make linear reciprocating motion in the vertical direction. The pressure plate 9 fixed at the bottom of the vertical rod 8 moves up and down accordingly. When the pressure plate 9 moves downward, the fluorocarbon coating above the pressure plate 9 in the top tank 2 enters the bottom tank 3 below the pressure plate 9 through the one-way valve 12, waiting for subsequent filtration. When the pressure plate 9 moves upward, the one-way valve 12 closes to prevent the fluorocarbon coating from flowing back. At the same time, the protrusion on the top of the pressure plate 9 helps to improve the pressure filtration efficiency. As the stepper motor 5 continues to work, the pressure plate 9 moves up and down continuously, gradually pressing the fluorocarbon coating from the top tank 2 into the bottom tank 3 for filtration.

[0036] Inside the bottom tank 3, the fluorocarbon coating is filtered through the screen 17 at the bottom of the filter box 16. The filter box 16 is placed in the placement groove 15 at the top of the fixing plate 13, and the sealing gasket 18 ensures that no leakage occurs during the filtration process. The fixing ring 19 is fixedly connected to the fixing plate 13 by the fixing bolt 20. The elastic sheet 21 is set at the bottom of the fixing ring 19 and contacts the top of the filter box 16. The elastic sheet 21 is arc-shaped in its natural state. When subjected to external force, it will deform and apply a downward elastic force to the filter box 16, thereby pressing the sealing gasket 18 at the bottom of the filter box 16 more tightly in the placement groove 15, improving the filtration effect of the fluorocarbon coating and ensuring the sealing and stability during the filtration process. After filtration, the filtered fluorocarbon coating is discharged from the bottom tank 3 through the discharge pipe 22, completing the entire filtration process. When the filter box 16 needs to be replaced, the fixing bolt 20 is loosened, and the elastic sheet 21 returns to its original shape due to the loss of external force, so that the filter box 16 can be easily removed for cleaning.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
