[0002] Deep filter paperboard is mainly used in pharmaceuticals and other fields with high purity requirements. During processing, deep filter paperboard can be made into various sizes and shapes according to customer requirements. Deep filter paperboard needs to be dried using a drying device during the production process. Traditional drying devices for deep filter paperboard production can basically meet people's needs, but there are still some problems, which are described below.

[0003] For example, CN216481910U discloses a continuous drying device for deep filter paperboard production, which relates to the technical field of deep filter paperboard production equipment. It includes a second mounting base plate, a collection frame fixed to the left side of the top of the second mounting base plate, vertical telescopic mechanisms symmetrically located on both sides of the bottom of the collection frame's inner cavity, a conveyor belt body and a water-pressing mechanism fixed to the top of the two sets of vertical telescopic mechanisms, with the conveyor belt body positioned in front of the water-pressing mechanism, and a horizontal telescopic mechanism fixed to the right side of the top of the second mounting base plate. A drying box is fixed to the top of the horizontal telescopic mechanism. When the deep filter paperboard moves to the right end of the conveyor belt body, the continuous drying device activates a third cylinder to retract, causing the drying box and the perforated plate to move synchronously to the rightmost position to automatically complete the stacking. Then, two sets of second cylinders are activated to extend to an appropriate length, facilitating the completion of the next cycle's stacking target and reducing the labor intensity of the workers.

[0004] However, in implementing the relevant technology, the following problems were found in the above-mentioned continuous drying device for deep filter paper production: it is difficult to maintain the stability of the continuous drying high temperature, which leads to the output of temperature and the instability of the continuous drying temperature in filter paper production, thereby reducing the working efficiency of continuous drying in filter paper production. Therefore, a continuous drying device for filter paper production is proposed. Utility Model Content

[0005] This invention proposes a continuous drying device for filter paperboard production, which solves the problem in related technologies that it is difficult to maintain the stability of the continuous drying high temperature, resulting in temperature output and instability of the continuous drying temperature in filter paperboard production, thereby reducing the working efficiency of continuous drying in filter paperboard production.

[0006] The technical solution of this utility model is as follows: A continuous drying device for filter paperboard production, comprising: a fixed frame, hollow discs fixedly installed at both ends of the fixed frame, a rotating drum rotatably connected between the hollow discs, and a power mechanism fixedly installed on the outer wall of the rotating drum;

[0007] A hollow auger is fixedly installed at one end of the inner wall of the rotating drum, and a hollow auger is fixedly installed at the other end of the inner wall of the rotating drum. The hollow auger is arranged opposite to the hollow auger, and both rotate inward to convey the material.

[0008] A mesh conveyor is fixedly installed on the top of the fixed frame, and the mesh conveyor passes through the hollow disc;

[0009] The outer wall of the hollow disc is equipped with multiple heating devices.

[0010] Preferably, the power mechanism includes a circular toothed plate fixedly installed at one end of the outer wall of the rotating drum, and a support plate fixedly installed on one side of the fixed frame.

[0011] Preferably, a motor is fixedly installed on the top of the support plate, and a gear is fixedly connected to the output end of the motor, with the gear meshing with the circular toothed plate.

[0012] Preferably, the plurality of heating devices include rectangular frames respectively fixedly installed on the outer wall of the hollow disc, and filter screens, fixing plates and heating wires respectively fixedly installed inside the rectangular frames, wherein the heating wires are located below the fixing plates and the fixing plates are located below the filter screens.

[0013] Preferably, three ventilation shells are fixedly installed through one side of the fixed plate from left to right, and a fan is fixedly installed inside each of the three ventilation shells.

[0014] The working principle and beneficial effects of this utility model are as follows: by starting the motor, the motor drives the gear to rotate, and the circular toothed plate connected by the gear linkage drives the rotating drum to rotate on the hollow disc, so that the second hollow auger and the first hollow auger rotate. The rotation of the second hollow auger and the first hollow auger causes the gas at both ends of the rotating drum to be transported inward, so as to maintain the continuous drying high temperature in the middle position of the rotating drum, effectively preventing the temperature inside the rotating drum from being output outward, thereby improving the stability of the continuous drying temperature in the production of filter paperboard.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1 - Figure 4 A continuous drying device for filter paperboard production includes: a fixed frame 1, hollow discs 2 fixedly installed at both ends of the fixed frame 1, a rotating drum 3 rotatably connected between the hollow discs 2, and a power mechanism fixedly installed on the outer wall of the rotating drum 3.

[0024] A hollow auger 7 is fixedly installed at one end of the inner wall of the rotating drum 3, and a hollow auger 8 is fixedly installed at the other end of the inner wall of the rotating drum 3. The hollow auger 8 and the hollow auger 7 are arranged opposite to each other, and both rotate inward to convey the material.

[0025] A mesh conveyor 9 is fixedly installed on the top of the fixed frame 1. The mesh conveyor 9 passes through the hollow disc 2. The power mechanism includes a circular toothed plate 4 fixedly installed on one end of the outer wall of the rotating drum 3, and a support plate 10 fixedly installed on one side of the fixed frame 1. A motor 5 is fixedly installed on the top of the support plate 10. A gear 6 is fixedly connected to the output end of the motor 5. The gear 6 is meshed with the circular toothed plate 4.

[0026] This utility model provides a continuous drying device for filter paperboard production. By starting the motor 5, the motor 5 drives the gear 6 to rotate. The circular toothed plate 4, which is linked to the gear 6, drives the rotating drum 3 to rotate on the hollow disc 2. This causes the hollow auger 2 8 and the hollow auger 1 7 to rotate. The rotation of the hollow auger 2 8 and the hollow auger 1 7 causes the gas at both ends of the rotating drum 3 to be transported inward. This is used to maintain a continuous high temperature for drying in the middle position of the rotating drum 3, effectively preventing the temperature inside the rotating drum 3 from being output outward, thereby improving the stability of the continuous drying temperature in filter paperboard production.

[0027] Furthermore, the outer wall of the hollow disc 2 is provided with a plurality of heating devices 11. The plurality of heating devices 11 include rectangular frames 111 fixedly installed on the outer wall of the hollow disc 2, and filter screens 112, fixing plates 113 and heating wires 115 fixedly installed inside the rectangular frames 111. The heating wires 115 are located below the fixing plates 113, and the fixing plates 113 are located below the filter screens 112. Three ventilation shells 114 are fixedly installed through the fixing plates 113 from left to right. Fans 116 are fixedly installed inside the three ventilation shells 114.

[0028] Specifically, by activating the fan 116, the fan 116 draws external gas into the interior of the rectangular frame 111. The drawn gas is blown onto the heating wire 115 to generate hot air. The generated hot air enters the interior of the hollow disc 2 and blows onto the filter paperboard conveyed by the mesh conveyor 9 for drying the filter paperboard. With the motor 5 driving the drum 3 to rotate, the hot air rotates and blows onto the filter paperboard, effectively drying the filter paperboard evenly.

[0029] While the fan 116 draws air, the filter screen 112 filters out impurities in the air, effectively preventing impurities from entering and adhering to the filter paperboard.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
