Description

Technical Field

[0001] This utility model relates to the field of coating oven technology, specifically to an oven that is easy to clean. Background Technology

[0002] During the lithium battery manufacturing process, the battery electrodes need to be dried in an oven after coating. When the battery electrodes move inside the oven to dry, the surface of the battery electrodes is covered with slurry that is not completely dried. This can easily contaminate the nozzles used to blow air onto the surface of the battery electrodes for drying. Therefore, it is necessary to clean and maintain the nozzles inside the oven regularly.

[0003] Due to the limitations of the internal structure, the ovens in related technologies are not easy to collect and discharge the cleaning fluid, which can easily lead to sludge buildup. Usually, the nozzles are designed to be easily detachable. When the nozzles need to be cleaned, they are removed separately for cleaning and then reinstalled. However, this cleaning method is labor-intensive, and the positional accuracy of the reinstalled nozzles is prone to decrease, which cannot meet the requirements of environments with high nozzle precision. Utility Model Content

[0004] This invention provides an easy-to-clean drying oven, solving the technical problem that existing drying ovens, by removing the air nozzles for cleaning and then reinstalling them, tend to have reduced positional accuracy of the reinstalled air nozzles, making them unsuitable for environments with high air nozzle precision requirements.

[0005] In view of this, the present invention provides an easy-to-clean drying oven, comprising:

[0006] The box includes an upper box and a lower box, the box having a closed state in which the upper box and the lower box abut against each other to form a closed space, and an open state in which the upper box and the lower box are separated.

[0007] A first housing is disposed within the upper box. A first cavity is disposed within the first housing. A plurality of first air nozzles are disposed at intervals along a first direction on the bottom end surface of the first housing. Each first air nozzle is provided with a first air blowing slit communicating with the first cavity.

[0008] The connection between the first housing and the first nozzle is provided with first inclined guide plates on both sides along the first direction. The first inclined guide plates extend away from the first housing and are gradually inclined upward.

[0009] The bottom of the lower housing is configured as a first tapered section that is wider at the top and narrower at the bottom, and the lowest end of the first tapered section is connected to a first drain pipe.

[0010] The drying oven according to this utility model, which is easy to clean, has at least the following beneficial effects:

[0011] By providing a first inclined guide plate at the connection between the first housing and the first nozzle, and setting the bottom of the lower housing as a first conical part, when the first nozzle needs to be cleaned, the housing is first switched to the open state, and then the cleaning gun is used to spray the cleaning fluid onto the surface of the first nozzle for cleaning. At this time, the cleaning fluid sprayed onto the surface of the first nozzle will fall into the lower housing under the action of gravity, and gather at the lowest end of the first conical part under the guiding action of the surrounding wall of the first conical part. After cleaning is completed, the cleaning fluid flowing into the first cavity is guided by the first inclined guide plate and converges into the first blowing slit, and falls into the bottom of the lower housing under the action of gravity, and gathers at the lowest end of the first conical part under the guiding action of the surrounding wall of the first conical part. This facilitates the collection of the cleaning fluid and discharge it from the first drain pipe, so as to achieve thorough washing of the first nozzle with cleaning fluid without disassembling the first nozzle, and fully discharge the cleaning fluid to avoid the accumulation of cleaning fluid.

[0045] The following is combined Figures 1 to 11 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, a convenient-to-clean drying oven is provided, comprising a box body 100 and a first shell 200. The box body 100 includes an upper box body 110 and a lower box body 120. The box body 100 has a closed state in which the upper box body 110 and the lower box body 120 abut against each other to form a closed space, and an open state in which the upper box body 110 and the lower box body 120 are separated. The first shell 200 is disposed inside the upper box body 110, and a first cavity 210 is disposed inside the first shell 200. The bottom end surface of the first shell 200 is along the first cavity 210. Multiple first air nozzles 300 are spaced apart in one direction. Each first air nozzle 300 is provided with a first air blowing slit 310 that communicates with the first cavity 210. At the connection between the first housing 200 and the first air nozzles 300, first inclined guide plates 211 are respectively provided on both sides along the first direction. The first inclined guide plates 211 extend away from the first housing 200 and are gradually inclined upward. The bottom end of the lower box 120 is provided with a first tapered part 121 that is wider at the top and narrower at the bottom. The lowest end of the first tapered part 121 is connected to a first drain pipe 410.

[0047] In this embodiment, the oven features a first inclined guide plate 211 at the connection between the first housing 200 and the first air nozzle 300, and the bottom of the lower housing 120 is configured as a first conical portion 121. When cleaning the first air nozzle 300 is required, the housing 100 is first switched to the open state, and then a cleaning gun is used to spray cleaning fluid onto the surface of the first air nozzle 300. The cleaning fluid sprayed onto the surface of the first air nozzle 300 falls into the lower housing 120 under gravity and accumulates in the first conical portion 121 under the guiding effect of the surrounding wall. At the lowest end; after cleaning is completed, the cleaning fluid flowing into the first cavity 210 is guided by the first inclined guide plate 211 and converges into the first blowing slit 310. Under the action of gravity, it falls into the bottom end of the lower box 120 and is concentrated at the lowest end of the first cone 121 under the guiding action of the surrounding wall of the first cone 121. This facilitates the collection of cleaning fluid and discharge from the first drain pipe 410, so as to achieve the goal of thoroughly washing the first air nozzle 300 with cleaning fluid without disassembling the first air nozzle 300 and fully draining the cleaning fluid to avoid the accumulation of cleaning fluid.

[0048] It should be noted that, because this embodiment does not require the first air nozzle 300 to be removed and reinstalled during the cleaning process, the cleaning operation is easier and the cleaning efficiency is higher; and the installation accuracy of the first air nozzle 300 remains basically unchanged before and after cleaning, ensuring that the oven in this embodiment meets the requirements of the operating environment that has high requirements for the installation accuracy of the first air nozzle 300.

[0049] Understandably, this embodiment can also be used to collect NMP waste liquid. Since the solvents of the slurry from different manufacturers are not consistent, or may be other solutes, when the solute in the slurry is too high, the concentration in the chamber 100 is too high during the drying process. When a temperature difference occurs in the oven, the high concentration of solute in the chamber 100 turns into water droplets that adhere to the inner wall of the chamber 100 and slide down to the bottom of the lower chamber 120 under the action of gravity. Under the guiding action of the surrounding wall of the first conical part 121, it gathers at the lowest end of the first conical part 121, thereby facilitating the collection of NMP waste liquid and its discharge from the first drain pipe 410.

[0050] It should be noted that in the process of cleaning the first air nozzle 300 in the oven of this embodiment, it is not necessary to remove and reinstall the first air nozzle 300. Therefore, the sealing performance at the connection between the base of the first air nozzle 300 and the first housing 200 can be ensured, thereby ensuring the uniformity of the air output of the first air nozzle 300 and thus ensuring the coating quality.

[0051] It should be noted that after cleaning is completed, the cleaning fluid flowing into the first cavity 210 can easily flow down along the first inclined guide plate 211 and converge into the first blowing slit 310, instead of accumulating at the right-angle connection, which helps to reduce the accumulation of cleaning fluid.

[0052] It should be noted that the cleaning solution dissolution ratio used in this embodiment is based on the actual slurry formula. The handheld cleaning gun nozzle used in this embodiment can be a high-pressure water gun nozzle or an electric booster water gun. The water source can be a high-pressure high-temperature car wash machine or a steam cleaner to supply the cleaning solution.

[0053] like Figure 5 As shown, specifically, one end of the housing 100 is provided with an electrode inlet 140, and the other end of the housing 100 is provided with an electrode outlet 150. The electrode inlet 140 and the electrode outlet 150 are used for the battery electrodes to enter and exit the housing 100.

[0054] It is understandable that the first direction mentioned in the text is parallel to the direction in which the battery electrodes are transported within the housing 100.

[0055] In specific applications, such as Figure 5As shown, the first inclined guide plate 211, which is connected to the first nozzle 300 closest to the electrode inlet 140, is connected to the side wall of the first cavity 210 so that the cleaning fluid falling on the side wall of the first cavity 210 relative to the electrode inlet 140 converges into the first blowing slit 310 of the first nozzle 300 closest to the electrode inlet 140 under the action of gravity; the first inclined guide plate 211, which is connected to the first nozzle 300 closest to the electrode outlet 150, is connected to the side wall of the first cavity 210 so that the cleaning fluid falling on the side wall of the first cavity 210 relative to the side wall of the electrode outlet 150 converges into the first blowing slit 310 of the first nozzle 300 closest to the electrode outlet 150 under the action of gravity.

[0056] In order to better guide the cleaning fluid flowing into the first cavity 210 into the first blowing slit 310, such as Figure 10 and Figure 11 As shown, specifically, the connection between the first housing 200 and the first nozzle 300 is provided with first inclined guide plates 211 on both sides along the second direction. The second direction and the first direction are perpendicular to each other and located on the same horizontal plane.

[0057] like Figure 5 and Figure 6 As shown, in some embodiments, the bottom end of the first cavity 210, located between two adjacent first nozzles 300, is configured as an inverted V-shaped first guide section 212. The first guide section 212, which is high in the middle and low around the edges, is suitable for the cleaning liquid falling on it to flow into the first blowing slit 310 under the action of gravity, which helps to reduce the amount of cleaning liquid remaining on the first guide section 212.

[0058] like Figure 5 As shown, in some embodiments, the top of the first cavity 210 includes a connecting portion 213. Second inclined guide plates 214 are symmetrically arranged on both sides of the connecting portion 213 along the first direction. One end of the second inclined guide plate 214 facing away from the connecting portion 213 is connected to the side wall of the first cavity 210. The second inclined guide plate 214 extends along the first direction away from the connecting portion 213 and gradually slopes downward. This arrangement facilitates the flow of cleaning fluid falling onto the second inclined guide plate 214 to the side wall of the first cavity 210 under the guiding action of the second inclined guide plate 214, and it easily flows into the first blowing slits 310 of the two first air nozzles 300 located at the beginning and end of the first direction under the action of gravity, which helps to reduce cleaning fluid residue.

[0059] like Figures 1 to 5 as well as Figure 7 , Figure 9 and Figure 10As shown, in some embodiments, a second housing 500 is provided inside the lower housing 120, and a second cavity 510 is provided inside the second housing 500. A plurality of second air nozzles 600 are provided at intervals along a first direction on the top surface of the second housing 500. The second air nozzles 600 are provided with a second air blowing slit 610 communicating with the second cavity 510. The bottom end of the second cavity 510 is provided as a second conical part 511, which is wider at the top and narrower at the bottom. The lowest end of the second conical part 511 is connected to a second drain pipe 420. When the second nozzle 600 needs to be cleaned, first switch the housing 100 to the open state, then hold the cleaning gun and spray the cleaning fluid onto the surface of the second nozzle 600 for cleaning. At this time, some of the cleaning fluid sprayed onto the surface of the second nozzle 600 will fall into the bottom of the lower housing 120 under the action of gravity, and gather at the lowest end of the first cone 121 under the guiding action of the surrounding wall of the first cone 121. At the same time, some of the cleaning fluid sprayed onto the second nozzle 600 will enter the second cavity 510 through the second blowing slit 610 under the action of gravity, and fall into the bottom of the second cavity 510. Under the guiding action of the surrounding wall of the second cone 511, it will gather at the lowest end of the second cone 511, thus facilitating the collection of the cleaning fluid entering the second cavity 510 and its discharge from the second drain pipe 420. This allows the second nozzle 600 to be thoroughly washed with cleaning fluid without disassembling it, and the cleaning fluid to be fully discharged to avoid the accumulation of cleaning fluid.

[0060] In specific applications, such as Figure 5 As shown, the first housing 200 is connected to the top of the upper housing 110 via the first connecting post 160, and the second housing 500 is connected to the bottom of the lower housing 120 via the second connecting post 170.

[0061] It should be noted that the first air nozzle 300 and the second air nozzle 600 are air nozzles with the same structure.

[0062] Understandably, the space between the first air nozzle 300 and the second air nozzle 600 in the vertical direction is used for the battery electrode to pass through.

[0063] In specific applications, the first housing 200 and the second housing 500 are symmetrically arranged in the vertical direction, and the first housing 200 and the second housing 500 are partially staggered in the first direction, so that the first air nozzle 300 and the second air nozzle 600 are alternately arranged in the first direction, thereby enabling the battery electrode to be dried evenly during the process of being transported from the electrode inlet 140 to the electrode outlet 150 in the first direction, thus improving the drying efficiency and effect of the battery electrode.

[0064] like Figures 1 to 3 as well as Figure 10As shown, in some embodiments, at least one side wall of the upper housing 110 is provided with an openable first operating door 111. When cleaning is required, the first operating door 111 can be opened so that a handheld cleaning gun can be inserted into the upper housing 110 to wash and clean the outer surface of the first housing 200 and the inner side wall of the upper housing 110.

[0065] Specifically, the first housing 200 is provided with an openable first maintenance door 220 at the position corresponding to the first operating door 111; when cleaning is required, the first maintenance door 220 can be opened so that a handheld cleaning gun can pass through the first operating door 111 and the first maintenance door 220 in sequence and be inserted into the first cavity 210 for water washing and cleaning, which facilitates thorough cleaning and helps to improve the cleanliness of the oven in this embodiment.

[0066] like Figures 1 to 3 as well as Figure 10 As shown, in some embodiments, at least one side wall of the lower housing 120 is provided with an openable second operating door 122. When cleaning is required, the second operating door 122 can be opened so that a handheld cleaning gun can be inserted into the lower housing 120 to wash and clean the outer surface of the second housing 500 and the inner side wall of the lower housing 120.

[0067] Specifically, the second housing 500 is provided with an openable and closable second maintenance door 530 at the position corresponding to the second operating door 122; when cleaning is required, the second maintenance door 530 can be opened so that a handheld cleaning gun can be passed through the second operating door 122 and the second maintenance door 530 in sequence and inserted into the second cavity 510 for water washing and cleaning, which facilitates thorough cleaning and helps to improve the cleanliness of the oven in this embodiment.

[0068] like Figure 3 , Figure 5 and Figure 7 As shown, in some embodiments, the portion of the top surface of the second housing 500 located between two adjacent second nozzles 600 is configured as a second guide portion 520, which is V-shaped. The second guide portion 520, being lower in the middle and higher around the edges, is suitable for channeling the cleaning fluid falling onto it into the lower middle section of the second guide portion 520 under gravity, and allowing it to fall to the bottom of the lower housing 120, thus reducing cleaning fluid residue on the second guide portion 520.

[0069] like Figure 5 and Figure 9As shown, in some embodiments, the two walls of the second conical portion 511 along the first direction are respectively connected to the side walls of the second cavity 510 by an inclined guide member 512. The inclined guide member 512 extends away from the second conical portion 511 along the first direction and is gradually inclined upward. The inclination angle of the inclined guide member 512 is greater than the inclination angle of the walls of the second conical portion 511. Considering that the cross-section of the first housing 200 perpendicular to the vertical direction is rectangular, and the side parallel to the first direction is the long side, by connecting the two walls of the second conical portion 511 along the first direction to an inclined guide member 512, the cleaning fluid falling on the side wall of the second cavity 510 along the first direction can quickly flow into the second conical portion 511 after falling into the inclined guide member 512 and being guided by the inclined guide member 512.

[0070] like Figure 4 and Figure 10 As shown, in some embodiments, a first valve 411 is provided on the first drain pipe 410, and a second valve 421 is provided on the second drain pipe 420. The second drain pipe is disposed inside the first drain pipe and is coaxially arranged. This arrangement reduces the space occupied by the first drain pipe 410 and the second drain pipe 420. Furthermore, after cleaning, the second valve 421 can be opened first to drain the cleaning fluid accumulated at the bottom of the second cavity 510, and then the first valve 411 can be opened for further drainage, resulting in a better drainage effect.

[0071] Specifically, the outer wall of the housing 100 is equipped with an air supply assembly, which is used to supply hot air to the first cavity 210 and the second cavity 510. With this configuration, when drying the battery electrode, the first valve 411 and the second valve 421 are closed, and the air supply assembly is activated to supply hot air to the first cavity 210 and the second cavity 510 respectively. The hot air entering the first cavity 210 is then blown onto the upper surface of the battery electrode through the first air slit 310 of the first air nozzle 300, and the hot air entering the second cavity 510 is then blown onto the lower surface of the battery electrode through the second air slit 610 of the second air nozzle 600. This not only avoids deformation of the battery electrode caused by air blowing only at one end of the battery electrode, but also ensures uniform drying of the battery electrode, improving the drying efficiency and effect of the battery electrode. On the other hand, during cleaning, after the cleaning liquid collected at the bottom of the lower chamber 120 and the bottom of the second cavity 510 is drained through the first drain pipe 410 and the second drain pipe 420, the first valve 411 and the second valve 421 are closed, and the air supply assembly is activated to deliver hot air. The hot air flows through every corner of the chamber 100, the first cavity 210, the second cavity 510, the first air slit 310 and the second air slit 610, drying the remaining small amount of cleaning liquid, thereby ensuring the cleanliness of the oven in this embodiment.

[0072] In specific applications, the air supply component adopts the existing air supply equipment used for conveying hot air. This embodiment does not involve any improvement to the structure of the air supply component, and will not be further elaborated here.

[0073] In specific applications, the first valve 411 is configured as a ball valve and the second valve 421 is configured as a butterfly valve; firstly, for ease of operation, the first valve 411 is configured on the part of the first drain pipe 410 extending outside the housing 100, and the second valve 421 is configured on the part of the second drain pipe 420 extending outside the housing 100.

[0074] like Figure 1 , Figure 2 and Figure 5 As shown, specifically, the top of the upper housing 110 is provided with a return air inlet 114 and an exhaust air inlet 115. During the start-up of the air supply assembly, both the exhaust air inlet 115 and the return air inlet 114 are opened. A portion of the hot air circulates into the housing 100 through the return air inlet 114, while a portion of the hot air is discharged from the housing 100 through the exhaust air inlet 115, improving drying efficiency and reducing energy consumption. Simultaneously, the return air boxes on the bottom surface of the first housing 200 and the top surface of the second housing 500 can be eliminated, further reducing cleaning difficulty.

[0075] like Figure 10 As shown, in some embodiments, a first air inlet is provided on one side wall of the first housing 200, which connects to the first cavity 210. A first air inlet 112 is provided on the upper housing 110 corresponding to the first air inlet, and the first air inlet 112 connects to the air supply assembly. The first air inlet 112 and the first air inlet are connected by a first inclined connecting portion 113, which extends towards the first air inlet and gradually slopes downwards. The inclined connecting portion 113 connects the first air inlet and the first air inlet 112, which helps prevent cleaning fluid from splashing into and accumulating in the first inclined connecting portion 113 during cleaning.

[0076] like Figure 5 As shown, specifically, a first anti-splash mesh plate 215 is provided inside the first air inlet end, which helps to prevent cleaning liquid from splashing into and accumulating in the first inclined connecting part 113 during cleaning.

The drive assembly is used to drive the housing 100 to switch between a closed state and an open state. By assembling the upper housing 110 and the lower housing 120 in a manner similar to a "clamshell opening and closing structure," and cooperating with the drive assembly to automatically switch the housing 100 between a closed state and an open state, the intensity of manual labor is reduced.

[0080] Specifically, the drive assembly includes a cylinder 130, which is hinged to one of the upper housing 110 and the lower housing 120, and the piston end of the cylinder 130 is hinged to the other of the upper housing 110 and the lower housing 120; preferably, the cylinder 130 is hinged to the outer side wall of the lower housing 120, and the piston end of the cylinder 130 is hinged to the outer side wall of the upper housing 110; the housing 100 is automatically switched between a closed state and an open state by controlling the extension and retraction of the piston end of the cylinder 130.

[0081] In another alternative embodiment, cylinder 130 is hinged to the outer side wall of upper housing 110, and the piston end of cylinder 130 is hinged to the outer side wall of lower housing 120.

[0082] In practical applications, cylinder 130 can also be replaced by an electric telescopic rod or a hydraulic cylinder, etc.

[0083] In specific applications, telescopic components can also be provided on at least two outer side walls of the lower housing 120. The telescopic ends of the telescopic components are connected to the upper housing 110. The upper housing 110 is driven to rise or fall vertically relative to the lower housing 120 through at least two telescopic components, thereby automatically switching the housing 100 between the closed and open states.

[0084] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
