Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly membrane anti-pollution technology, and in particular to an anti-pollution device for PVC environmentally friendly membrane. Background Technology

[0002] PVC film is a film material made of polyvinyl chloride. Due to its excellent properties such as high transparency, good chemical resistance, water resistance, and flame retardancy, it is widely used in many industries. PVC undergoes feeding, kneading, cutting, and compounding processes in an open mill, completing the material processing. The processed material then enters a calender or extruder for the next process.

[0003] During the processing of PVC in an open mill, some oils and other components evaporate. In the past, a suction pipe was installed above the open mill to remove the evaporated oil and gas. However, because the suction pipe causes the oil and gas containing chemical components to condense, it accumulates and eventually falls into the material below, contaminating it.

[0004] Open mills process PVC films of different compositions, so they are often used on mixed production lines. However, when producing environmentally friendly PVC films, if the condensate in the suction pipe falls onto the material in the open mill below, it will contaminate the entire product, making it impossible to produce a qualified environmentally friendly film. Utility Model Content

[0005] The purpose of this utility model is to provide a pollution prevention device for PVC environmentally friendly film, which solves the problem that when producing environmentally friendly PVC film, once the condensate in the suction pipe falls onto the material in the open mill below, it will contaminate the entire product and make it impossible to produce qualified environmentally friendly film.

[0006] To achieve the above objectives, a pollution prevention device for PVC environmentally friendly film is provided, comprising: a PVC open mill, with fixed frames fixedly connected to both sides of one end of the PVC open mill, a suction pipe fixedly connected to the top center of the fixed frame, a flow ventilation hole provided inside the suction pipe, an inward turning layer provided at the bottom of the inner wall of the flow ventilation hole, a guide strip penetrating inside the inward turning layer, a holding tray fixedly connected to the bottom of the guide strip, and an inner groove provided between the inward turning layer and the flow ventilation hole.

[0007] Both sides of the inner wall of the ventilation hole are fixedly connected to concave frames, and sponge frames are inserted into the concave frames.

[0008] The sponge frame has a filter sponge fixedly connected inside.

[0009] A pointed cone is fixedly connected to the middle of the bottom end of the sponge frame.

[0010] A manual valve is provided at the bottom of the holding tray.

[0011] An arc-shaped groove is provided in the middle of the outer side of the air intake pipe.

[0012] A disassembly plate is inserted into the inside of the arc-shaped groove, and the disassembly plate is fixedly connected to the sponge frame.

[0013] A hand-held block is fixedly connected to the middle of the outer side of the disassembly plate.

[0014] The above-mentioned solution has the following beneficial effects: 1. This utility model is equipped with a suction pipe, a guide strip, a collection tray, and a manual valve. When the air flows through the suction pipe, the air flow can be achieved through the air vent. During the air flow, the air will come into contact with the guide strip and rise. At this time, the volatile air will condense after contacting the guide strip. Then, the air will flow into the inside of the collection tray through the guide strip for collection. When cleaning is required, it can be periodically treated by opening the manual valve.

[0015] 2. This utility model is equipped with a flow guide strip, a holding tray, a filter sponge, and a disassembly plate. The flow guide strip guides the gas back into the holding tray, while the upward-flowing gas can be filtered again by the filter sponge to separate the gas from the condensate. The condensate drips downward through the pointed cone into the holding tray, while the condensate inside the filter sponge can be pulled out by the hand block. The disassembly plate moves the sponge frame outward, which facilitates the replacement and cleaning of the filter sponge and improves the portability of use. Attached Figure Description

[0021] Reference Figure 1-4 This utility model discloses an anti-pollution device for a PVC environmentally friendly film, comprising a PVC open mill 1. Fixed frames 2 are fixedly connected to both sides of one end of the PVC open mill 1. A suction pipe 3 is fixedly connected to the top center of the fixed frame 2. During the PVC open mill 1's smelting operation, the generated gas is extracted through an external air pump structure connected to the suction pipe 3, achieving a discharge function. The suction pipe 3 has a ventilation hole 4 inside, allowing air to circulate through the ventilation hole 4. During the flow process, the gas will come into contact with the guide strip 8 and rise. The bottom of the inner wall of the flow vent 4 is provided with an inward turning layer 5, and the guide strip 8 runs through the inside of the inward turning layer 5. The volatile gas will condense after contacting the guide strip 8, and then flow to the inside of the holding tray 6 through the guide strip 8 for collection. The bottom of the guide strip 8 is fixedly connected to the holding tray 6, and the flow is guided to the inside of the holding tray 6 again through the guide strip 8. An inner groove 12 is provided between the inward turning layer 5 and the flow vent 4.

[0022] A concave frame 15 is fixedly connected to both sides of the inner wall of the ventilation hole 4. A sponge frame 13 is inserted inside the concave frame 15. When gas enters the air intake pipe 3 and comes into contact with the inner wall of the ventilation hole 4, the condensate will accumulate inside the sponge frame 13. A filter sponge 14 is fixedly connected inside the sponge frame 13. The filter sponge 14 performs a filtration operation to separate the gas from the condensate. The condensate drips down through the pointed cone into the inside of the collection tray 6. A pointed cone is fixedly connected to the bottom center of the sponge frame 13. The bottom of the collection tray 6 is equipped with... A manual valve 7 is provided, which can be used to perform periodic cleaning. An arc-shaped groove 11 is provided in the middle of the outer side of the suction pipe 3. A disassembly plate 9 is inserted into the middle of the arc-shaped groove 11. The disassembly plate 9 drives the sponge frame 13 to be taken out, which facilitates the replacement and cleaning of the filter sponge 14 and improves the portability of use. The disassembly plate 9 and the sponge frame 13 are fixedly connected. A hand block 10 is fixedly connected to the middle of the outer side of the disassembly plate 9. The condensate inside the filter sponge 14 can be pulled out through the hand block 10, and the disassembly plate 9 drives the sponge frame 13 to be taken out.

[0023] In operation, the PVC open mill 1 is used for smelting. The generated gas is extracted through an external air pump connected to a suction pipe 3 for discharge. As the gas flows through the suction pipe 3, it passes through the vent 4. During this flow, the gas comes into contact with the guide strip 8 and rises. The evaporating gas condenses upon contact with the guide strip 8 and is then guided by the guide strip 8 to the inside of the collection tray 6 for collection. Cleaning can be performed periodically by opening the manual valve 7. When the gas enters the suction pipe... The inner wall of the tube 3 contacts the inner wall of the vent hole 4. At this time, the condensate flowing through the tube will accumulate inside the sponge frame 13 and be guided back to the inside of the holding tray 6 by the guide strip 8. The upward flowing gas can be filtered again by the filter sponge 14 to separate the gas from the condensate. The condensate drips down into the inside of the holding tray 6 through the pointed cone. The condensate inside the filter sponge 14 can be pulled out by the hand block 10, and the disassembly plate 9 can be used to remove the sponge frame 13. This makes it convenient to replace and clean the filter sponge 14, improving the portability of use.
