Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to an air inlet and dehumidification device for ovens. Background Art

[0002] When an oven is used in the production process of lithium-ion batteries, the electrode material coated on the electrode is dried. The oven uses heated dry air to dry the surface of the electrode. The solvent on the surface of the electrode evaporates and is discharged with the exhaust fan. In order to save the energy required for heating, part of the exhausted hot air passes through the return air duct and the fresh air duct to enter the oven, thereby increasing the gas temperature before heating. Generally, the solvent of the negative electrode material is pure water, so the hot air contains water vapor, and the humidity content of the air is different throughout the year, so there will also be moisture in the fresh air. This will cause the gas in the fresh air duct to contain more moisture, which will prolong the drying time of the oven and also cause poor consistency in the drying of the electrode.

[0003] The existing technology is to remove moisture from the gas in the fresh air duct through a rotary dehumidifier. However, since the fan blades of the rotary dehumidifier are small, it is difficult to remove all moisture from the gas in the fresh air duct. Utility Model Content

[0004] The technical problem to be solved by the utility model is how to remove all moisture from the gas in the fresh air duct.

[0005] The utility model solves the above technical problems through the following technical means:

[0006] The utility model provides an oven air inlet dehumidification device, comprising a dehumidification box and a drying box, wherein a dehumidification filter element is horizontally placed inside the dehumidification box, wherein the dehumidification filter element is a corrugated silica gel plate and a partition plate alternately arranged, and an axial channel is formed by the corrugated silica gel plate, and metal silicate is attached to the surface of the corrugated silica gel plate; when the dehumidification filter element is saturated with water, it is placed in the drying box for drying.

[0007] Beneficial effects: The utility model removes moisture from the gas through the dehumidification box, and then dries the dehumidification filter element through the drying box. The utility model forms a large number of axial channels through the corrugated silica gel plate to facilitate the passage of gas. Metal silicate is attached to the surface of the corrugated silica gel plate. The metal silicate increases the adsorption holes of the corrugated silica gel plate, thereby improving the ability of the corrugated silica gel plate to adsorb moisture. Since the corrugation increases the contact area between the gas and the channel, the dehumidification filter element has an extremely high ability to adsorb water vapor, which can completely remove moisture from the gas, while reducing heating energy consumption and ensuring the stability of the moisture content of the gas entering the oven, ensuring the consistency of the electrode drying.

[0008] Preferably, the drying box is connected to a drying fan.

[0009] Beneficial effect: The utility model uses a drying fan to pass air through the drying box to bring part of the moisture in the dehumidification filter element out of the drying box.

[0010] Preferably, the dehumidification box body is provided with an air inlet and an air outlet, the air inlet is connected to the fresh air pipeline, and the air outlet is connected to the oven.

[0011] Preferably, the drying box is provided with a hot air inlet and a hot air outlet, the hot air inlet is connected to a heating device, and the heating device is connected to a drying fan.

[0012] Beneficial effect: The utility model uses a drying fan to heat the air through a heating device to turn it into hot air. The hot air enters the drying box and turns the moisture in the dehumidification filter into water vapor and is discharged through the hot air outlet, so that the dehumidification filter can be recycled repeatedly.

[0013] Preferably, the oven is connected to the fresh air duct of the dehumidification box through a return air duct.

[0014] Preferably, the dehumidification filter element is provided with multiple layers of corrugated silica gel plates.

[0015] Preferably, the number of layers of the corrugated silicone plate is 16, and the radius of the corrugation is 5 mm.

[0016] Preferably, the length and width of the dehumidification filter element are both 80 mm.

[0017] Preferably, the dehumidification box and the drying box are three-dimensional in shape.

[0018] Preferably, the dehumidification box and the drying box are in the shape of a cube, with the length, width and height all being 100 mm. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] according to Figure 1-3 As shown, this embodiment provides an oven air inlet dehumidification device, including a dehumidification box 10 and a drying box 20, wherein a dehumidification filter element 13 is horizontally placed inside the dehumidification box 10, and the dehumidification filter element 13 is formed by alternating corrugated silica gel plates 132 and partitions 131, and metal silicate is attached to the surface of the corrugated silica gel plates 132. The metal silicate increases the adsorption holes of the corrugated silica gel plates 132, thereby improving the ability of the corrugated silica gel plates 132 to adsorb moisture. The corrugated silica gel plates 132 form a large number of axial channels. When the gas passes through its channels, the contact area between the corrugated silica gel plates 132 and the hot air can be increased due to the waveform, and the corrugated silica gel plates 132 can completely adsorb moisture in the gas.

[0026] When the dehumidification filter element 13 is fully saturated with water, the dehumidification filter element 13 is removed from the dehumidification box 10 and placed in a drying box 20. The drying box 20 is provided with a hot air inlet 21 and a hot air outlet 22. A heating device 23 is provided at the hot air inlet 21. The heating device 23 is connected to a drying fan 24. Figure 1As shown, the drying fan 24 passes the air into the heating device for heating, turning it into hot air. The hot air passes into the drying box 20 to dry the dehumidification filter element 13 that is saturated with moisture. The hot air can turn the moisture in the dehumidification filter element 13 into water vapor, which is discharged through the hot air outlet, thereby drying the dehumidification filter element 13. The dried dehumidification filter element 13 can be placed back in the dehumidification box 10 for dehumidification work.

[0027] The dehumidification box body 10 is provided with an air inlet 11 and an air outlet 12. The air inlet 11 is connected to the fresh air pipeline (not shown in the figure), and the air outlet 12 is connected to the oven (not shown in the figure) through a pipeline. The oven is connected to the fresh air pipeline through a return air pipeline (not shown in the figure), which can increase the temperature of the gas in the fresh air pipeline and reduce the drying time of the oven.

[0028] The dehumidification box 10 and the drying box 20 are cube-shaped, with a length, width and height of 100 mm. The dehumidification filter element 13 is formed by alternating corrugated silica gel plates 132 and partitions 131, wherein the corrugated silica gel plates 132 are arranged in multiple layers, for example, 16 layers. The corrugated radius of the corrugated silica gel plates 132 is 5 mm, and the length and width of the dehumidification filter element 13 are 80 mm.

[0029] In summary, this embodiment removes moisture from the air in the fresh air duct using the dehumidification box 10, and then dries the dehumidification filter 13 using the drying box 20, allowing the dehumidification filter 13 to be reused, saving costs. This embodiment completely removes moisture from the air using the corrugated silica gel plate 132 in the dehumidification filter 13, reducing heating energy consumption while ensuring stable moisture content in the air entering the oven and consistent electrode drying.
