Description

Technical Field

[0001] This utility model relates to the field of thin film processing technology, specifically to a PM film processing heating device. Background Technology

[0002] PM membrane is a high-performance filter membrane with excellent filtration accuracy and long service life. It is widely used in chemical, pharmaceutical, and environmental protection fields. During the processing of PM membrane, the raw material of PM membrane needs to be heated to facilitate the formation of PM membrane.

[0003] However, due to the varying sizes of the membrane raw materials, uneven heating during the heating process can easily affect the heating effect. To ensure uniform heating of the membrane raw materials, a patent document with publication number CN221561921U describes a process where a first servo motor drives a spiral crusher to break down polyester film, reducing the size of the polyester film raw materials to a suitable size. A second servo motor then drives a rotating rod and a stirring rod to stir the polyester film raw materials heated in the heating tank, ensuring uniform heating. This process ensures even heating of the polyester film raw materials during the heating process, preventing uneven heating and improving the overall heating effect.

[0004] Based on the above-disclosed technical content, theoretically, the implementation of the relevant technical structure is beneficial for the uniform heating of the membrane raw material. However, according to the description in the above-disclosed technical content, the gas generated by heating the membrane raw material is discharged to the outside of the heating chamber through the exhaust pipe. The filter screen can filter the polluting gas discharged from the exhaust pipe to prevent the polluting gas from being directly discharged to the outside and polluting the outside air. As the amount of membrane raw material processed in the heating chamber increases, the particles in the gas generated by heating the membrane raw material are easily stuck in the filter holes of the filter screen. As the number of particles blocking the filter holes increases, the area of ​​the filter holes blocked by particles on the filter screen will increase until the filter holes are completely blocked by particles. At this time, the filter screen will interfere with the continuous flow of gas. Utility Model Content

[0017] Please see Figure 1 , Figure 4 and Figure 7A PM membrane processing heating device includes a heating chamber body 1. The inner wall of the heating chamber body 1 has a cavity, and a heating wire 2 is fixedly installed inside the cavity. The heating wire 2 heats the membrane material inside the heating chamber body 1. A stirring assembly 3 is installed inside the heating chamber body 1. The rotation of the stirring assembly 3 ensures thorough stirring of the membrane material within the heating chamber body 1, resulting in uniform heating. An electric push rod 4 is fixedly installed on the back of the heating chamber body 1. The extension of the output shaft inside the electric push rod 4 allows the chamber cover body 5 to not only connect to but also separate from the heating chamber body 1, facilitating cleaning of the interior of the heating chamber body 1.

Regarding the connection between the feed funnel 23 and the heating box body 1, the feed funnel 23 is fixedly installed on the upper left side of the auger box body 6. The upper end of the auger box body 6 is fixedly connected to the exhaust pipe 7 located on the right side of the feed funnel 23. The exhaust pipe 7 is used to remove impurities from the gas generated after the membrane raw material is heated. The end of the exhaust pipe 7 away from the feed funnel 23 is movably connected to the filter pipe 9 through the fastening bolt 8.

The inner wall of the middle part of the filter pipe 9 is fixedly sleeved with a first filter screen 10, and the inner wall of the right end of the filter pipe 9 is fixedly sleeved with a second filter screen 11. The inner diameter of the filter holes on the second filter screen 11 is smaller than the diameter of the filter holes on the first filter screen 10. This achieves that the gas in the filter pipe 9 first passes through the first filter screen 10 for primary filtration, and then passes through the second filter screen 11 for secondary filtration, thereby improving the filtration effect of particulate matter in the gas.

The installation of the second side plate 22 serves to connect the electric push rod 4 and the box cover body 5.

[0023] Working principle: In use, firstly, the membrane material is fed from the inside of the feed funnel 23 into the inside of the auger box body 6. Due to the conveying action of the auger inside the auger box body 6, the membrane material falls into the inside of the heating box body 1. Power is supplied to the heating wire 2 through an external power source, allowing the heating wire 2 to heat the membrane particles inside the heating box body 1. Then, the power supply to the rotary motor 19 is turned on. After the rotary motor 19 is turned on, it drives the rotation of the annular block 301 through the connection of the rotating shaft 18. At the same time, the rotation of the annular block 301 drives the synchronous rotation of the scraper 303 through the connection of the extension rod 302, so that the membrane material is fully heated. The material is heated evenly and evenly. After heating, the material is discharged from the inside of the discharge pipe 16 to the outside of the heating box body 1. Then, the gas generated by the heating of the raw material inside the heating box body 1 flows from the exhaust pipe 7 to the inside of the filter pipe 9. The gas in the filter pipe 9 first passes through the primary filter screen 10 and then passes through the second filter screen 11 for secondary filtration, thereby improving the filtration effect of particulate matter in the gas. Finally, by turning on the power of the electric push rod 4, the output shaft inside the electric push rod 4 is extended to separate the box cover body 5 from the heating box body 1, so that the inside of the heating box body 1 can be cleaned.
