Description

Technical Field

[0001] This utility model relates to the field of diaphragm paper production, and in particular to a dryer for producing supercapacitor diaphragm paper. Background Technology

[0002] Supercapacitors, also known as electrochemical capacitors, are devices that store energy through electrochemical reactions at the interface between electrodes and electrolytes. They can complete charging and discharging in a short time and are high-power energy storage devices that fall between traditional capacitors and batteries. Supercapacitors are mainly composed of current collectors, electrode materials, electrolytes, and separators.

[0003] Supercapacitor separator paper is mainly composed of polymer membrane (gel membrane), glass fiber and cellulose. The separator paper is located between the two electrodes, isolating the positive and negative electrodes to prevent short circuits, while allowing electrolyte ions to pass through smoothly. It is a key component affecting the energy density, power density and cycle life of the capacitor. After production, it must be dried to remove moisture.

[0004] For example, patent document CN219916946U discloses a drying device for producing supercapacitor separator paper, belonging to the field of drying equipment technology. It includes a drying table with a drying channel on its inner side, and two clamping rollers installed on the inner side of one end of the drying channel. This invention solves the problem of drying the separator paper by directly blowing hot air onto its surface. While this method is relatively effective, hot air has a low thermal density and is generally a poor conductor of heat. In this device, a servo motor drives blades to rotate via a connecting shaft, generating airflow. This airflow is heated by resistance wires to form hot air. The hot airflow enters the ventilation slot through the drying chamber, heating the outer side of the drying rollers. The drying rollers transfer heat to the supercapacitor separator paper on their outer side. The hot airflow also coats the surface of the drying rollers, further heating and drying the supercapacitor separator paper.

[0005] In existing technologies, the mainstream drying method is to remove the moisture on the separator paper by blowing hot air, thereby achieving the drying effect. However, the hot airflow after this method is used still carries a considerable amount of heat, and direct discharge will lead to energy waste. Utility Model Content

[0006] The purpose of this invention is to provide a dryer for producing supercapacitor diaphragm paper in order to solve the above-mentioned problems.

The double drying cylinder groups are hollow and filled with heat-conducting oil. The separator paper moves forward in a "U" shape under the action of the double drying cylinder groups. A hot air mechanism is provided inside the drying chamber. The hot air mechanism includes several air distribution boxes fixedly connected to the drying chamber. The air distribution boxes are located on the left and right sides of the separator paper and are mirror-symmetrical. Several air nozzles are fixedly connected to the air distribution boxes.

[0013] Preferably, the oil heat pipe assembly is made of copper pipe, the outside of the T-shaped return air pipe is covered with insulation material, and the outside of the first return oil pipe and the second return oil pipe are covered with insulation material.

[0014] The beneficial effects are as follows: by utilizing the characteristics of the Venturi tube, during the continuous flow of new airflow, some of the hot airflow carrying moisture is drawn back into the distribution box for reuse through negative pressure and T-shaped return air duct.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1-8As shown, a dryer for producing supercapacitor separator paper includes a device body, the device body includes a drying box 101, the left and right sides of the drying box 101 are rotatably connected with guide roller sets 102 through bearings, a plurality of evenly distributed rectangular double dryer cylinder sets 103 are rotatably connected inside the drying box 101, the double dryer cylinder sets 103 are hollow and filled with heat-conducting oil inside, the separator paper advances in a "zigzag" shape under the action of the plurality of double dryer cylinder sets 103, a hot air mechanism is arranged inside the drying box 101, the hot air mechanism includes a plurality of air distribution boxes 201 fixedly connected with the drying box 101, the air distribution boxes 201 are arranged on the left and right sides of the separator paper and are mirror-symmetrical, a plurality of hot air nozzles 203 are fixedly connected to the air distribution boxes 201, a Venturi tube 202 is fixedly connected to the rear side of the air distribution box 201, the middle necks of the two Venturi tubes 202 are fixedly connected with the same T-shaped return air pipe 204, a plurality of air suction branches 205 are fixedly connected to the top of the drying box 101, the other end of the T-shaped return air pipe 205 is communicated with the air suction branches 205, a heating mechanism is arranged on the rear side of the drying box 101. In use, the heating mechanism sends hot oil and hot air into the double dryer cylinder sets 103 and the air distribution boxes 201 respectively, so that the double dryer cylinder sets 103 heat up to dry the separator paper in contact with them, the hot air in the air distribution boxes 201 is blown onto the separator paper through the hot air nozzles 203, and the air distribution boxes 201 are arranged in mirror symmetry, so that the separator paper can be ensured to be evenly stressed while being dried by hot air blowing, avoiding damage from position limitation. After the hot air blows and carries away moisture, it leaves the drying box 101 through the air suction branches 205. At this time, due to the characteristics of the Venturi tube 202, during the continuous inflow of new air flow, part of the moisture-containing hot air flow is sucked back into the air distribution boxes 201 through negative pressure and the T-shaped return air pipe 204 for reuse, which can realize the reuse of waste heat and prevent the "glazing" of the paper web surface due to excessive drying in the initial stage of drying, protecting the pore structure.

[0031] The front end of a single dryer cylinder in the double dryer cylinder set 103 is fixedly connected with a pulley 104, the pulleys 104 on adjacent double dryer cylinder sets 103 are connected through a synchronous belt, the rear end of a single dryer cylinder in the double dryer cylinder set 103 is fixedly connected with symmetric gears 105, the two symmetric gears 105 are meshed with each other, a driving motor 106 is fixedly connected to the drying box 101, the output end of the driving motor 106 is fixedly connected with a driving gear 107, and the driving gear 107 is meshed with one of the symmetric gears 105.

[0032] Several suction channels 205 are fixedly connected to a main suction channel 206 at their tops. An air pump 207 is fixedly connected to the main suction channel 206. A condenser is connected to the outside of the main suction channel 206. In use, the air pump 207 slowly and continuously draws the airflow from the drying chamber 101. The residual hot airflow leaves the drying chamber 101 from the suction channels 205 and then flows into the main suction channel 206.

[0033] The heating mechanism includes an air inlet channel 302 fixedly connected to the rear side of the drying chamber 101. A blower 301 is fixedly connected to one end of the air inlet channel 302. The blower 301 is existing technology, and its specific structure will not be described here. Several sets of symmetrically arranged oil distribution boxes 305 are fixedly connected to the air inlet channel 302. The upper and lower oil distribution boxes 305 are connected by an oil heat pipe assembly 304. The air inlet channel 302 is fixedly connected to the rear end of the venturi tube 202. In use, the blower 301 blows outside air into the air inlet channel 302. When the airflow passes through the oil heat pipe assembly 304, heat exchange occurs, and the airflow is heated. Then the hot airflow enters the air distribution box 201 from the air inlet channel 302.

[0034] The oil distribution tank 305 is rotatably and sealed to the rear end of the double drying cylinder assembly 103. A heating oil tank assembly 303 is fixedly connected to the rear side of the air inlet channel 302. The heating oil tank assembly 303 has heating and oil pumping functions. Existing equipment that meets the above functions is selected. The heating oil tank assembly 303 is connected to the lower oil distribution tank 305 through a pipeline. A first return oil pipe 306 is fixedly connected to the lower end of the heating oil tank assembly 303. The other end of the first return oil pipe 306 is rotatably and sealed to the upper double drying cylinder assembly 103. A second return oil pipe 307 is fixedly connected to the lower end of the heating oil tank assembly 303. The other end of the second return oil pipe 307 is rotatably connected to the lower double drying cylinder group 103. In use, the heating oil tank assembly 303 heats the heat transfer oil, and then the heat transfer oil pump sends it into the lower oil distribution tank 305. The hot oil is divided, part of which enters the corresponding lower double drying cylinder group 103, and part of which enters the upper oil distribution tank 305 through the oil heat pipe group 304. Then the oil distribution tank 305 enters the corresponding upper double drying cylinder group 103. After leaving the double drying cylinder group 103, the heat transfer oil returns to the heating oil tank assembly 303 through the second return oil pipe 307 and the first return oil pipe 306.

The T-shaped return air duct 204 is covered with insulation material on the outside. The first return oil pipe 306 and the second return oil pipe 307 are also covered with insulation material on the outside. The insulation material prevents heat loss when transporting hot airflow and heat transfer oil.

[0036] Working principle: The diaphragm paper belt enters the drying chamber 101 from one side guide roller group 102. Under the action of several double drying cylinder groups 103, the diaphragm paper advances in a "V" shape, and then leaves the drying chamber 101 from the other side guide roller group 102. The drive motor 106 drives the drive gear 107 to rotate, and the drive gear 107 drives the symmetrical gear 105 to rotate. The two symmetrical gears 105 rotate simultaneously, driving the double drying cylinder groups 103 to rotate. Several double drying cylinder groups 103 achieve synchronous rotation through pulleys 104 and synchronous belts. The dual-drying cylinder assembly 103 drives the diaphragm paper to move, and the heating oil tank assembly 303 heats the heat transfer oil. The heat transfer oil is then pumped into the lower oil distribution tank 305, where it is split. Part of the hot oil enters the corresponding lower dual-drying cylinder assembly 103, and part enters the upper oil distribution tank 305 through the oil-conducting heat pipe assembly 304. The oil then flows into the corresponding upper dual-drying cylinder assembly 103 from the distribution tank 305. After leaving the dual-drying cylinder assembly 103, the heat transfer oil returns to the heating oil tank assembly 303 via the second return oil pipe 307 and the first return oil pipe 306. The blower 301 draws outside air into the air inlet channel 302. As the airflow passes through the oil-conducting heat pipe assembly 304, heat exchange occurs, heating the airflow. The hot air then enters the air distribution box 201 from the air inlet channel 302. The heating mechanism sends hot oil and hot air into the dual drying cylinder assembly 103 and the air distribution box 201, respectively. The dual drying cylinder assembly 103 heats up, drying the diaphragm paper in contact with it. The hot air in the air distribution box 201 is blown onto the diaphragm paper through the blower nozzles 203. The air distribution box 201 is mirror-symmetrically arranged. While the hot air is blowing and drying, it can ensure that the diaphragm paper is subjected to uniform force and avoid damage to the limiting position. After the hot air blows away the moisture, it leaves the drying box 101 through the suction channel 205. At this time, due to the characteristics of the Venturi tube 202, in the process of continuously flowing in new airflow, some of the hot airflow with moisture is drawn back into the air distribution box 201 for reuse through negative pressure and T-shaped return air pipe 204. In this way, the residual heat can be reused and the paper surface can be prevented from "glazing" due to excessive drying in the early stage of drying, thus protecting the pore structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
