Description

Technical Field

[0001] This utility model relates to the field of filter paper production technology, specifically to an environmentally friendly filter paper drying device. Background Technology

[0002] Filter paper is the main functional component of filter cartridges, and drying it is a crucial step in the production process. Traditional filter paper drying equipment suffers from numerous problems, including energy and resource waste. Therefore, various energy-efficient drying devices for filter paper production and processing have emerged on the market.

[0003] In the prior art, Chinese Patent Publication No. CN209960925U discloses an energy-saving and environmentally friendly filter paper drying device, including a dryer. A fixed box is fixedly connected to the top of the inner wall of the dryer, and air ducts are connected to the left and right sides of the bottom of the fixed box. This utility model uses the left and right movement of the fixed column to drive the rotation of the sector gear. The sector gear, in conjunction with the bushing, rotates on the U-shaped frame, driving the gear to rotate. The rotation of the gear drives the rotation of the rotating rod, which in turn causes the placement plate to shake, achieving a uniform drying effect. Finally, the fan is started to transmit the air force to the inside of the conveying pipe through the connecting pipe. The conveying pipe delivers the air force to the inside of the air duct and, together with the drying lamp, dries the filter paper. This solves the problem of unnecessary water waste caused by traditional filter paper drying devices that use hot water combustion for heat conduction or hot air combustion for drying, thus avoiding the waste of water resources and financial costs, reducing the user's drying time, and improving the practicality of the drying device.

[0004] The filter paper drying device provided in the aforementioned patent uses a fan to deliver airflow to a designated location via a connecting pipe. However, the inner side of the filter paper drying device contains a conveying mechanism to achieve simultaneous conveying and drying of the filter paper. Uniform drying of the filter paper is crucial during the drying process, but existing heating mechanisms struggle to provide even heating to the entire drying device, resulting in poor drying performance. Furthermore, the air inlet of the drying device cannot filter the air, allowing dust to easily adhere to the filter paper. Utility Model Content

The heater 2 is used to heat the airflow entering the air guide duct 1. The air guide duct 1 is used to introduce airflow, thus facilitating the heating of the airflow in conjunction with the heater 2. Multiple heating tubes 22 are provided at the end of the heater 2 facing the air guide duct 1, and the heating tubes 22 are inserted into the interior of the air guide duct 1. The heating tubes 22 facilitate rapid heating of the airflow after it enters the air guide duct 1. An air inlet pipe 15 is provided at the other end of the air guide duct 1, facilitating the entry of external air into the interior of the air guide duct 1. A filter element 4 is connected to the top of the air inlet pipe 15, and the inner cavity of the filter element 4 communicates with the inner cavity of the air inlet pipe 15. The filter element 4 facilitates the filtration of external air entering the air inlet pipe 15, preventing dust in the air from adhering to the filter paper. The filter element 4 is fitted with an air duct 5. The side of the air duct 5 has uniform air vents. The bottom of the air duct 5 is connected to the top of the air inlet pipe 15. The air duct 5 is used to guide the airflow through the filter element 4, and at the same time, the air duct 5 also protects the filter element 4.

[0030] like Figure 2 As shown, one end of the air guide duct 1 is provided with a disassembly hole 11, which facilitates the disassembly, assembly, and maintenance of the heater 2. Multiple air outlet pipes 12 are evenly distributed on the bottom surface of the air guide duct 1, allowing the heated air inside the air guide duct 1 to be smoothly discharged and enter the drying equipment. A flange 13 is provided at the bottom end of the air outlet pipe 12, facilitating the connection between the air guide duct 1 and the body of the drying equipment.

[0031] like Figure 4 As shown, the top of the air inlet pipe 15 is provided with an adapter plate 16 for connecting with the air duct 5, and the middle of the adapter plate 16 is provided with an installation ring 17 for connecting with the bottom of the filter element 4.

[0034] like Figure 7 As shown, the bottom of the air hood 5 is provided with a connector 51, which is threadedly connected to the adapter plate 16. There is a gap between the air hood 5 and the filter element 4. This structure makes it easy to ensure that the air around the air hood 5 enters the air suction pipe, and at the same time, the air hood 5 can also prevent the filter element 4 from being easily damaged.

[0035] Working principle: When in use, connect the air hood 5 to the air supply equipment. The air supply equipment supplies air so that the airflow passes through the filter element 4 and the air inlet pipe 15 and enters the air guide tube 1. The heater 2 heats the airflow inside the air guide tube 1, so that the airflow temperature inside the air guide tube 1 rises. The heated airflow enters the drying equipment through the air outlet pipe 12 and blows onto the filter paper, thereby achieving the purpose of drying the filter paper. Compared with the prior art, this application installs a heater 2 inside the guide tube to heat the airflow. At the same time, the air inlet pipe of the guide tube is connected to a filter element 4 to filter the air entering the guide tube, thereby ensuring that the airflow for drying the filter paper is sufficiently clean and preventing dust from the air from sticking to the filter paper. Multiple air outlet pipes 12 are evenly arranged at the bottom of the guide tube. This structure allows the air inlets to be evenly arranged from the front to the rear of the drying equipment. The air outlet pipes 12 are connected to the air inlets, so that the heated airflow can be drawn into the drying equipment by the fan 3, so that there are air inlets from front to back inside the drying equipment. With the help of the air distribution plate, the drying equipment can evenly dry the filter paper from front to back.
