Description

Technical Field

[0001] This utility model relates to the field of polytetrafluoroethylene membrane cleaning technology, specifically to a cleaning device for polytetrafluoroethylene membranes. Background Technology

[0002] Polytetrafluoroethylene (PTFE) is generally known as a "non-stick coating" or "easy-to-clean material." This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. PTFE also has high-temperature resistance and an extremely low coefficient of friction, making it suitable for lubrication and ideal for cleaning the inner lining of water pipes. During processing, PTFE films often contain dust on their surface, requiring surface treatment.

[0003] The prior art discloses a film cleaning device with application number CN202021338522.X. This utility model cleans the film by immersing it in a washing tank and then rotating a guide roller. However, this device can only effectively clean the surface of the film, and the guide roller cannot brush the bottom of the film, resulting in poor film cleaning effect. Moreover, after cleaning, there is no structure for cleaning water marks on the film surface, resulting in water marks remaining on the film surface after cleaning. As the film is conveyed backward, the film carries the water marks outward, which can easily cause the water marks to drip onto other workstations. Further improvements are needed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a cleaning device for polytetrafluoroethylene membranes to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for polytetrafluoroethylene (PTFE) membranes, comprising a cleaning tank, a guide roller, a connecting shaft, and a fixing frame inside the cleaning tank; a brush cylinder on the outer surface of the connecting shaft; a driving bevel gear fixed at one end of the connecting shaft, and a driven gear at the other end of the connecting shaft, with the driving bevel gear meshing with the driven bevel gear; a piston box on the outer surface of the cleaning tank, with a reciprocating screw mounted on one side of the piston box; a driven bevel gear fixed at one end of the reciprocating screw; a threaded seat fitted onto the outer surface of the reciprocating screw; a piston rod fixed on one side of the threaded seat; and a piston plate fixed at one end of the piston rod extending into the piston box; an air inlet pipe and an air outlet pipe connected to one side of the piston box, with one end of the air outlet pipe extending into the cleaning tank and connected to an air outlet pipe; a motor mounted on the back of the cleaning tank via a mounting bracket, with the output end of the motor connected to a driving gear; and a compression plate connected inside the fixing frame via a spring.

[0006] Furthermore, both the air inlet pipe and the air delivery pipe are equipped with one-way valves on their outer surfaces.

[0007] By adopting the above technical solution, the one-way valve ensures that the air intake pipe can only take in air and cannot exhaust air, while the air delivery pipe can only deliver air, thus preventing cleaning water from being drawn into the piston box.

[0008] Furthermore, the intake pipe is equipped with a filter element inside.

[0009] By adopting the above technical solution, the filter element can filter the outside air and prevent external dust from entering the cleaning tank.

[0010] Furthermore, a guide rod is fixed to one side of the extrusion plate, and the guide rod is movably connected to the fixing frame.

[0011] By adopting the above technical solution, the stability of the extrusion plate is improved under the action of the guide rod, so that the extrusion plate can only move horizontally.

[0012] Furthermore, the extrusion plate is provided in two sets, and the inner side of the two sets of extrusion plates is provided with a protective pad, which is made of rubber material.

[0013] By adopting the above technical solution, the two sets of extrusion plates can simultaneously scrape away water stains on both sides of the film, and the protective pad of the rubber material is flexible to prevent the film from being scratched.

[0014] Furthermore, two sets of heating blocks are installed inside the lower part of the cleaning tank.

[0015] By adopting the above technical solution, the heating block can heat the cleaning water to a certain temperature, and the warm water can quickly remove stains, thus improving the cleaning effect.

[0016] Furthermore, a control panel is installed above the outer surface of the cleaning tank, and the heating block and the motor are both electrically connected to the control panel.

[0017] By adopting the above technical solution, staff can control the heating block and motor through the control panel.

[0018] Furthermore, a drain outlet is provided on one side of the cleaning tank, and a valve is installed on the outer surface of the drain outlet.

[0019] By adopting the above technical solution, after cleaning is completed, the staff can open the valve to discharge the wastewater, which makes it easier to replace the cleaning water.

[0020] Furthermore, the driven gear is provided in two sets, the two sets of driven gears mesh with each other, and the driving gear meshes with one of the sets of driven gears.

[0021] By adopting the above technical solution, when the driving gear rotates, it can cause a set of driven gears to rotate, and when a set of driven gears rotates, it can drive another set of driven gears to rotate.

[0022] Furthermore, the outer surface of the vent pipe has several fine holes.

[0023] By adopting the above technical solution, air can be discharged from several fine holes to form fine bubbles. After the bubbles burst, they can generate an impact force, which further enables the stains to be quickly removed from the film.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model comprises a brush cylinder, a connecting shaft, a driven gear, a driving gear, a driving bevel gear, a driven bevel gear, a reciprocating screw, a threaded seat, a piston rod, a piston plate, an air inlet pipe, an air outlet pipe, and an air outlet pipe. When cleaning a film, the film passes between two sets of films. The operator starts the motor, which rotates the driving gear, which in turn rotates the driven gear, causing the connecting shaft to rotate the brush cylinder. The rotation of the brush cylinder cleans the surface and bottom of the film. Furthermore, the rotation of the connecting shaft drives the driving bevel gear, which in turn drives the driven bevel gear, which in turn cleans the reciprocating screw. The rotation of the lead screw causes the threaded seat to drive the piston rod to move back and forth, thus causing the piston plate to perform left and right piston movements within the piston box. Outside air enters the piston box through the air inlet pipe, and the air outlet pipe can input air into the air outlet pipe, and then discharge it from the fine holes on the air outlet pipe. The air forms fine bubbles in the cleaning water near the brush cylinder, and the brush bristles can break the bubbles when the brush cylinder rotates. The impact force generated when the bubbles burst further cleans the stains on the film, greatly improving the cleaning effect on the film and solving the drawback of existing technologies that can only clean one side of the film, and greatly improving the cleaning efficiency.

[0026] 2. This utility model is equipped with a fixed frame, spring, extrusion plate and protective pad. After the film is cleaned, it passes through the fixed frame. Under the action of the spring, the extrusion plate and the protective pad can scrape off the water stains on the film, thereby avoiding the problem of residual water stains on the film dripping onto the work station later, and improving the practicality of the cleaning device.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1: A cleaning device for polytetrafluoroethylene membranes, such as... Figures 1-5As shown, the system includes a cleaning tank 1. Inside the cleaning tank 1 are a guide roller 18, a connecting shaft 6, and a fixing frame 23. A brush cylinder 21 is provided on the outer surface of the connecting shaft 6. One end of the connecting shaft 6 is fixed with a driving bevel gear 7, and the other end is provided with a driven gear 14. The driving bevel gear 7 meshes with the driven bevel gear 5. A piston box 2 is provided on the outer surface of the cleaning tank 1, and a reciprocating screw 3 is installed on one side of the piston box 2. One end of the reciprocating screw 3 is fixed with the driven bevel gear 5. A threaded seat 4 is sleeved on the outer surface of the reciprocating screw 3. A piston rod 9 is fixed on one side of the threaded seat 4, and one end of the piston rod 9 extends into the interior of the piston box 2 and is fixed with a piston plate 20. An air inlet pipe 11 and an air delivery pipe 10 are respectively connected to one side of the piston box 2. One end of the air supply pipe 10 extends into the interior of the cleaning tank 1 and is connected to the air outlet pipe 22. The outer surfaces of the air inlet pipe 11 and the air supply pipe 10 are equipped with one-way valves. Under the action of the one-way valves, the air inlet pipe 11 can only take in air and cannot exhaust air, while the air supply pipe 10 can only supply air, preventing the cleaning water from being drawn into the piston box 2. The back of the cleaning tank 1 is equipped with a motor 16 via a mounting bracket 15, and the output end of the motor 16 is connected to a drive gear 17. The inside of the fixed bracket 23 is connected to a pressing plate 26 via a spring 25. A guide rod 24 is fixed on one side of the pressing plate 26, and the guide rod 24 is movably connected to the fixed bracket 23. Under the action of the guide rod 24, the stability of the pressing plate 26 is improved, so that the pressing plate 26 can only move horizontally.

[0037] See Figure 2 and Figure 5 In the above embodiment, the extrusion plate 26 is provided in two sets, and the inner side of the two sets of extrusion plates 26 is provided with a protective pad 27. The protective pad 27 is made of rubber material. The two sets of extrusion plates 26 can simultaneously scrape off water stains on both sides of the film. The rubber material protective pad 27 is flexible and prevents the film from being scratched.

[0038] See Figures 1-3 In the above embodiment, a drain outlet 12 is provided on one side of the cleaning tank 1, and a valve is installed on the outer surface of the drain outlet 12. After cleaning, the staff can open the valve to discharge the wastewater after cleaning, which makes it convenient to replace the cleaning water.

[0039] See Figure 2 and Figure 4 In the above embodiment, the driven gear 14 is provided in two sets, the two sets of driven gear 14 mesh with each other, and the driving gear 17 meshes with one set of driven gear 14. When the driving gear 17 rotates, it can cause one set of driven gear 14 to rotate. When one set of driven gear 14 rotates, it can drive the other set of driven gear 14 to rotate.

[0040] See Figures 3-4In the above embodiment, the outer surface of the air outlet pipe 22 is perforated with several fine holes. After the air is discharged from the several fine holes, it can form fine bubbles. After the bubbles burst, they can generate an impact force, which further enables the stains to be quickly removed from the film.

[0041] Example 2: To prevent external dust from being drawn into the cleaning tank, Example 2 improves upon Example 1. (See attached document.) Figure 6 The air intake pipe 11 is equipped with a filter element 8 inside, which can filter the outside air and prevent outside dust from entering the cleaning tank 1.

[0042] Example 3: To further improve the cleaning effect and efficiency, Example 3 is an improvement on Example 1. (See attached document for details.) Figure 3 Two sets of heating blocks 19 are installed at the bottom of the interior of the cleaning tank 1. The heating blocks 19 can heat the cleaning water to a certain temperature, and the warm water can make the stains quickly detach, thus improving the cleaning effect.

[0043] Referring to the figure, in the above embodiment, a control panel 13 is installed above the outer surface of the cleaning tank 1, and the heating block 19 and the motor 16 are both electrically connected to the control panel 13. The operator can control the heating block 19 and the motor 16 through the control panel 13.

[0044] The implementation principle of this utility model is as follows: When cleaning the film, the film passes between two sets of films. The operator starts the motor 16, and the rotation of the motor 16 causes the drive gear 17 to rotate. The rotation of the drive gear 17 causes the driven gear 14 to rotate, which in turn causes the connecting shaft 6 to drive the brush cylinder 21 to rotate. The rotation of the brush cylinder 21 can brush the surface and bottom of the film. Moreover, when the connecting shaft 6 rotates, it will drive the drive bevel gear 7 to rotate. The rotation of the drive bevel gear 7 can drive the driven bevel gear 5 to rotate. The rotation of the driven bevel gear 5 can drive the reciprocating screw 3 to rotate. The rotation of the reciprocating screw 3 causes the threaded seat 4 to drive the piston rod 9 to move back and forth, thereby making... The piston plate 20 moves left and right within the piston box 2. Outside air enters the piston box 2 through the air inlet pipe 11. The air supply pipe 10 can input air into the air outlet pipe 22, and then discharge it from the fine holes on the air outlet pipe 22. The air forms fine bubbles in the cleaning water near the brush cylinder 21. When the brush cylinder 21 rotates, the bristles can break the bubbles. When the bubbles burst, they generate an impact force to further clean the stains on the film. The cleaned film passes through the fixing frame 23. Under the action of the spring 25, the extrusion plate 26 and the protective pad 27 can extrude the film. When the film is rolled up, the protective pad 27 can scrape off the water stains on the film.
