Description

Technical Field

[0001] This application relates to the field of coating machine oven technology, and in particular to a negative pressure chamber condensate collection structure, an oven, and a coating machine. Background Technology

[0002] In the electrode production process, the electrode needs to be dried using a coating machine oven to remove the solvent and form an electrode structure with good electrochemical performance. However, during the drying process, the temperature inside the negative pressure chamber of the oven is high. The hot and humid air and high-temperature solvent gas inside the negative pressure chamber easily mix with the cooler air outside at the outlet of the negative pressure chamber, forming condensate that drips onto the electrode, thus affecting the coating process. Utility Model Content

[0003] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a negative pressure chamber condensate collection structure, an oven, and a coating machine, which can reduce the amount of condensate dripping onto the electrode.

[0004] An embodiment of the first aspect of this application provides a negative pressure chamber condensate collection structure, including:

[0005] A drain plate is provided at the outlet of the negative pressure chamber of the oven, and the drain plate has a collection chamber;

[0006] The liquid guiding structure has a flow guiding channel, which is in communication with the liquid in the collection chamber. The flow guiding channel is used to guide the coolant in the collection chamber to the outside of the negative pressure chamber.

[0007] Furthermore, the collection cavity has a drainage bottom wall, which is inclined, and the installation height of the drainage bottom wall on the side closer to the guide channel is less than the installation height of the drainage bottom wall on the side farther away from the guide channel.

[0008] Furthermore, the drainage plate includes two baffles spaced apart from each other on the bottom wall of the drainage system. The two baffles and the bottom wall of the drainage system enclose the collection cavity, wherein the top of the collection cavity is an opening.

[0009] Furthermore, the liquid guiding structure includes a delivery pipe connected to the drainage plate, wherein the delivery pipe forms the guiding channel.

[0010] Furthermore, the liquid guiding structure includes a liquid receiving tray, which is disposed between the conveying pipe and the diversion tray. The liquid receiving tray has a liquid receiving cavity, the inlet end of which is in fluid communication with the collecting cavity, and the outlet end of which is in communication with the guiding channel. The cross-sectional area of ​​the liquid receiving cavity is larger than the cross-sectional area of ​​the guiding channel.

[0011] Furthermore, the liquid guiding structure includes a connector, which is installed outside the negative pressure chamber and connected to the end of the delivery pipe away from the collection chamber.

[0012] An embodiment of the second aspect of this application provides an oven, including a chamber and a negative pressure chamber condensate collection structure as described above, the chamber having the negative pressure chamber, and the drain plate being disposed at the outlet of the negative pressure chamber.

[0013] Furthermore, the oven includes an exhaust pipe, one end of which is connected to the oven body, wherein the exhaust pipe has an exhaust channel that is in fluid communication with the negative pressure chamber.

[0014] Furthermore, an exhaust port is formed at the connection between the exhaust pipe and the housing, and the exhaust port is located above the drainage plate.

[0015] An embodiment of the third aspect of this application provides a coating machine, including the oven as described above.

[0016] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects:

[0017] In the negative pressure chamber condensate collection structure, oven, and coating machine provided in this application embodiment, a diversion plate is installed at the outlet of the negative pressure chamber in the oven body. The collection chamber of the diversion plate collects the condensate formed at the outlet of the negative pressure chamber, and the condensate in the collection chamber is guided away through the guide channel. This reduces the amount of condensate dripping onto the electrode, which helps ensure the normal production of the electrode and thus guarantees the product quality of the electrode. At the same time, using the collection chamber to collect the condensate formed at the outlet of the negative pressure chamber reduces the corrosion of the seals between the negative pressure chamber and the oven body by the condensate, which helps increase the service life of the seals and further ensures the normal production of the electrode.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] In coating equipment, the main factors contributing to condensation at the oven outlet include: slow solvent evaporation, resulting in incomplete evaporation and liquid formation at the outlet; improper settings of coating speed, thickness, and other parameters, leading to insufficient drying of the coating within the oven and residual liquid at the outlet; excessively high oven temperature causing rapid solvent evaporation and condensation at the outlet; uneven hot air circulation resulting in uneven heating of the coating material and incomplete solvent evaporation in some areas, leading to liquid formation at the outlet; and high internal oven temperature causing humid air to condense and form water droplets upon encountering cooler external air at the outlet. If this condensate is not drained, it will affect the electrode coating yield, corrode internal oven components, and shorten the equipment's lifespan.

[0030] In view of this, the first aspect of this application discloses a condensate collection structure for a negative pressure chamber, which reduces the impact of condensate on electrode production and production equipment by collecting the condensate formed at the outlet of the negative pressure chamber 11.

[0031] See Figures 1 to 3 As shown, an embodiment of the first aspect of this application discloses a negative pressure chamber condensate collection structure, including a drainage plate 100 and a liquid guiding structure.

[0032] Specifically, the diversion plate 100 is located at the outlet of the negative pressure chamber 11 of the oven. The diversion plate 100 has a collection chamber 110, which is used to collect the condensate formed at the outlet of the negative pressure chamber 11 to reduce the condensate dripping onto the electrode 1. The liquid guiding structure has a guiding channel, which is in liquid communication with the collection chamber 110. The guiding channel is used to guide the coolant in the collection chamber 110 to the outside of the negative pressure chamber 11.

[0033] It is understandable that the drainage plate 100 is located inside the negative pressure chamber 11 2, rather than outside the negative pressure chamber 11 3, as... Figure 1 and Figure 3 As shown.

[0034] In practical applications, the drainage plate 100 is located above the electrode 1, and the collection chamber 110 of the drainage plate 100 is used to collect the condensate formed above the electrode 1.

[0035] In the negative pressure chamber condensate collection structure provided in this application embodiment, a diversion plate 100 is installed at the outlet of the negative pressure chamber 11 of the oven body 10. The collection chamber 110 of the diversion plate 100 collects the condensate formed at the outlet of the negative pressure chamber 11, and the condensate in the collection chamber 110 is guided away through the guide channel, reducing the occurrence of condensate dripping onto the electrode 1, which helps to ensure the product quality of the electrode 1. At the same time, using the collection chamber 110 to collect the condensate formed at the outlet of the negative pressure chamber 11 reduces the corrosion of the seals of the oven body 10 by the condensate, which helps to increase the service life of the seals and further ensures the normal production of the electrode.

[0036] In one embodiment, the collecting chamber 110 has a drainage bottom wall, which is inclined, and the installation height of the side of the drainage bottom wall near the guide channel is less than the installation height of the side of the drainage bottom wall away from the guide channel. Therefore, when condensate falls into the collecting chamber 110, the condensate can flow along the drainage bottom wall to the guide channel, allowing the condensate in the collecting chamber 110 to be guided to the guide channel and discharged from the negative pressure chamber 11 through the guide channel. By setting the inclined drainage bottom wall, the condensate can automatically flow to the guide channel under gravity, achieving condensate discharge while saving the need for structures such as pumps to drive the condensate flow, thus simplifying the structural design.

[0037] In one embodiment, see Figure 1 and Figure 2The drainage plate 100 includes two baffles 111 spaced apart on the bottom wall of the drainage system. The two baffles 111 and the bottom wall of the drainage system enclose a collection cavity 110, wherein the top of the collection cavity 110 is open. Specifically, the bottom wall of the drainage system and the two spaced baffles 111 form a trough-like structure, and the top of the collection cavity 110 is open, that is, the top of the drainage plate 100 has an opening. Thus, the collection cavity 110 can not only be used to collect the condensate formed in the negative pressure cavity 11, but also to guide the condensate away.

[0038] In this embodiment, the drainage plate 100 has an elongated structure and is disposed above the electrode 1, with its length direction being substantially parallel to the width direction of the electrode 1. The drainage plate 100 has a certain width in the conveying direction of the electrode 1.

[0039] It is worth mentioning that the width of the drainage plate 100 in the conveying direction of the electrode 1 should not be too large, so as to avoid the humid gas in the negative pressure chamber 11 from mixing directly with the external cold air below the drainage plate 100 to form condensate and drip onto the electrode 1.

[0040] In one embodiment, see Figure 1 and Figure 2 The liquid guiding structure includes a delivery pipe 220, which is connected to the drainage plate 100, wherein the delivery pipe 220 forms a flow guiding channel.

[0041] In one embodiment, see Figure 1 and Figure 2 The liquid guiding structure includes a liquid receiving tray 210, which is disposed between the conveying pipe 220 and the guide tray 100. The liquid receiving tray 210 has a liquid receiving cavity 211, the inlet end of which is in fluid communication with the collecting cavity, and the outlet end of which is in communication with the guiding channel. The cross-sectional area of ​​the liquid receiving cavity 211 is larger than that of the guiding channel. In this embodiment, the condensate in the guide tray 100 first flows into the liquid receiving cavity 211, and then flows from the outlet end of the liquid receiving cavity 211 into the guiding channel. Because the cross-sectional area of ​​the liquid receiving cavity 211 is larger than that of the guiding channel, the overflow of condensate during its flow from the guide tray 100 into the guiding channel can be reduced.

[0042] In this embodiment, see Figure 1 and Figure 2 The upper end of the receiving tray 210 is the liquid inlet end, which has an opening, and the liquid outlet end is located at the lower end of the receiving tray 210. As shown in the figure, one end of the guide plate 100 abuts against the upper end of the receiving tray 210, and the condensate in the guide plate 100 can flow along the collecting chamber 110 and flow into the receiving chamber 211 from the opening at the upper end of the receiving tray 210, and then flow into the guide channel from the bottom of the receiving tray 210.

[0043] In one embodiment, see Figure 2 and Figure 3 The liquid guiding structure includes a connector 230, which is installed outside the negative pressure chamber 11 and connected to the end of the delivery pipe 220 away from the collection chamber 110.

[0044] In practical applications, the condensate in the guide channel can be discharged directly from the connector 230 into the collection container, or a pipe, such as a hose, can be connected to the connector 230 to guide the condensate away. No limitation is made here.

[0045] The second aspect of this application discloses an oven, including a chamber 10 and a negative pressure chamber condensate collection structure as described above. The chamber 10 has a negative pressure chamber 11, and a drain plate 100 is disposed at the outlet of the negative pressure chamber 11.

[0046] It is worth understanding that the embodiments of the second aspect of this application have all the technical effects of the aforementioned negative pressure chamber condensate collection structure, which will not be repeated here.

[0047] In one embodiment, the oven includes an exhaust duct 12, one end of which is connected to the chamber 10. The exhaust duct 12 has an exhaust channel that is in fluid communication with the negative pressure chamber 11. The exhaust duct 12 is used to discharge steam from the negative pressure chamber 11 to further reduce the formation of condensate in the negative pressure chamber 11.

[0048] In one embodiment, an exhaust port is formed at the connection between the exhaust pipe 12 and the housing 10, and the exhaust port is located above the guide plate 100. In this way, the probability of vapor above the electrode 1 mixing with cold air and generating condensate can be reduced.

[0049] In one embodiment, see Figure 3 The oven includes a first adjusting plate 13, which is adjustablely installed on the upper side of the outlet of the negative pressure chamber 11. Specifically, the oven includes a first adjusting plate 13 and a first adjusting mechanism. The first adjusting plate 13 is provided with a first adjusting groove that extends vertically. The first adjusting mechanism includes a first adjusting bolt 14, which passes through the first adjusting groove and is connected to the chamber body 10. By tightening the first adjusting bolt 14, the first adjusting plate 13 and the chamber body 10 can be relatively fixed. Loosening the first adjusting bolt 14 allows the installation height of the first adjusting plate 13 to be adjusted.

[0050] In one embodiment, the oven includes a second adjusting plate, which is adjustablely installed below the outlet of the negative pressure chamber 11. Specifically, the oven includes a second adjusting plate and a second adjusting mechanism. The second adjusting plate is provided with a second adjusting groove that extends vertically. The second adjusting mechanism includes a second adjusting bolt that passes through the second adjusting groove and is connected to the chamber body 10. By tightening the second adjusting bolt, the second adjusting plate and the chamber body 10 can be relatively fixed. Loosening the second adjusting bolt allows adjustment of the installation height of the second adjusting plate.

[0051] The third aspect of this application discloses a coating machine, including the oven as described above, which has all the technical effects of the aforementioned oven, and will not be repeated here.
