Description

Technical Field

[0001] This utility model relates to the field of nanocellulose coated diaphragm drying technology, and in particular to a nanocellulose coated diaphragm drying device. Background Technology

[0002] With the continuous improvement of modern technology, my country's battery production technology is developing faster and faster. The battery separator is a layer of membrane material between the positive and negative electrodes of the battery. It is a very critical part of the battery and has a direct impact on battery safety and cost. However, during the production process, the battery separator is often coated with some materials to improve the structural stability of the separator. Nanocellulose is a common chemical coating. The coated separator often needs to be dried in a dryer before it can be used.

[0003] Existing nanocellulose-coated diaphragm drying equipment dries the diaphragm by heating during use. In order to reduce energy consumption, excess heat is collected and reused. However, this heat contains a large amount of humid gas. When reused, this humid gas can easily increase the humidity of the drying gas, thereby reducing the drying quality and efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide a nanocellulose-coated diaphragm drying device.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A nanocellulose-coated diaphragm drying device includes a body with symmetrically mounted frames on the upper part of the body. A drying mechanism is installed between the two sets of frames, and a recovery mechanism is provided on the outside of the frames. The recovery mechanism includes an exhaust pipe, an exhaust pump, and an exhaust pipe. A processing mechanism is installed on the exhaust pipe. The processing mechanism includes a housing connected to the exhaust pipe. A heating frame is installed on one side of the housing. A drying screen is installed on one side of the heating frame inside the housing and is snap-fitted to the housing. The processing end of the drying screen is located inside the housing.

[0007] Preferably, the drying mechanism includes an air intake fan, a wind deflector, and a heater, wherein the air intake fan has multiple sets.

[0008] Preferably, the wind deflector is located below the air intake fan, and the heater is located below the wind deflector.

[0009] Preferably, the air extraction pipe is located inside the machine body and is connected to the air extraction pump.

[0010] Preferably, the gas supply pipe is connected to the air pump, and the end of the gas supply pipe is connected to the frame.

[0011] Preferably, slots are provided on both sides of the machine body, and a guide roller is provided inside the machine body on one side of the slot.

[0012] Preferably, a dustproof net is provided on the frame at the top of the air intake fan, and the dustproof net is fastened to the frame.

[0013] The beneficial effects of this technology are:

[0014] By setting up a processing mechanism, the heat transported during the heat transfer process of the recovery mechanism will enter the casing of the processing mechanism. At this time, the heat will come into contact with the heating rack inside the casing. The heating rack will reduce the moisture in the heat. After the moisture is reduced, the heat will come into contact with the drying mesh. The drying mesh can absorb and filter the residual moisture in the heat, thereby keeping the heat dry. This avoids increasing the humidity of the drying gas during the heat recovery process and improves the drying quality and efficiency. Attached Figure Description

[0020] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0021] like Figures 1-3As shown, this embodiment provides a nanocellulose coated membrane drying device, including a body 1. A frame 2 is symmetrically installed on the upper part of the body 1, supporting a drying mechanism 3. The drying mechanism 3 is installed between two sets of frames 2. A recovery mechanism 4 is provided on the outside of the frame 2. The recovery mechanism 4 includes an extraction pipe 401, an extraction pump 402, and a gas delivery pipe 403. A processing mechanism 5 is installed on the gas delivery pipe 403. The processing mechanism 5 includes a housing 501 connected to the gas delivery pipe 403. The housing 501 can fix a heating frame 502 and a drying net 503. A heating frame 502 is installed on one side inside the housing 501, reducing moisture in the heat through heating. A drying net 503 is installed inside the housing 501 on one side of the heating frame 502, absorbing and filtering residual moisture in the heat. The drying net 503 is snap-fitted to the housing 501, and the processing end of the drying net 503 is located inside the housing 501.

[0022] like Figures 2-3 As shown, the drying mechanism 3 includes an intake fan 301, a wind deflector 302, and a heater 303. The intake fan 301 has multiple sets, which facilitates the intake fan 301 to draw outside air into the frame 2.

[0023] like Figures 1-2 As shown, the wind deflector 302 is located below the intake fan 301, and the heater 303 is located below the wind deflector 302. The wind deflector 302 can reduce the speed of the incoming air. After the decelerated air comes into contact with the heater 303, it forms hot air that blows onto the diaphragm, thereby drying it.

[0024] like Figures 1-2 As shown, the air extraction pipe 401 is located inside the machine body 1, and the air extraction pipe 401 is connected to the air extraction pump 402, so that the air extraction pump 402 can extract the heat inside the machine casing 501 through the air extraction pipe 401.

[0025] like Figures 1-2 As shown, the gas supply pipe 403 is connected to the air pump 402, and the end of the gas supply pipe 403 is connected to the frame 2. The heat extracted by the air pump 402 enters the frame 2 through the gas supply pipe 403 for recycling.

[0026] like Figures 1-2 As shown, slots 6 are provided on both sides of the machine body 1, and a guide roller 7 is provided inside the machine body 1 on one side of the slot 6, so that the diaphragm can enter the machine body 1 through the slot 6 and be guided by the guide roller 7.

[0027] like Figures 1-2 As shown, a dustproof net 8 is provided on the top of the intake fan 301 on the frame 2, and the dustproof net 8 is snapped to the frame 2. It can prevent external dust from entering the machine body 1 during the operation of the intake fan 301.

[0028] The working principle of this device is as follows: In actual use, the diaphragm enters the machine body 1 through the slot 6 and is guided by the guide roller 7. During the diaphragm's movement, the intake fan 301 draws in outside air into the frame 2. The airflow speed is reduced by the baffle 302. The reduced airflow comes into contact with the heater 303, forming hot air that blows onto the diaphragm, thus drying it. During the operation of the intake fan 301, the dustproof net 8 prevents outside dust from entering the machine body 1. Furthermore, during the drying process, the suction pump 402 extracts heat from the casing 501 through the suction pipe 401. The heat extracted by 402 enters the frame 2 through the gas pipe 403 for recovery and utilization. At the same time, during the heat transmission process of the recovery mechanism 4, the transmitted heat will enter the casing 501 in the processing mechanism 5. At this time, the heat comes into contact with the heating rack 502 in the casing 501. The heating rack 502 reduces the moisture in the heat. The heat after the moisture is reduced will come into contact with the drying net 503. At this time, the drying net 503 can absorb and filter the residual moisture in the heat, thereby keeping the heat dry and avoiding increasing the humidity of the drying gas during the heat recovery and utilization process, thus improving the drying quality and efficiency.

[0029] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
