[0026] Reference Figure 1-Figure 4 An embodiment of the utility model provides an oven exhaust structure, including an oven body 1, wherein a feed port 12 and a discharge port 6 are respectively provided on two opposite sides (front and rear sides) of the oven body 1, and the electrode piece 7 to be dried after coating enters the oven from the feed port 12, and then exits the oven from the discharge port 6, and a roller assembly 8 is also provided inside the oven body 1, and the roller assembly 8 includes a plurality of rollers, and the plurality of rollers are used to support the walking of the electrode piece 7.

[0027] The other two opposite sides (left and right sides) of the oven body 1 are provided with exhaust ducts (left exhaust duct 2 and right exhaust duct 3 respectively), the top side of the oven body 1 is provided with an air intake duct 4, and a spoiler component 9 and a flow equalizer component 10 are provided below the air intake duct 4 in the oven body 1, the air intake duct 4 is used to introduce fresh air (hot air), the spoiler component 9 is used to disperse the fresh air, and the flow equalizer component 10 is used to evenly distribute the fresh air.

[0028] In the utility model, fresh air (hot air) enters the oven body 1 from the air inlet duct 4, and then is dispersed once under the action of the spoiler component 9. The dispersed fresh air is dispersed twice under the action of the flow-leveling component 10, so that the fresh air is blown downward evenly to improve the uniformity of drying the electrode 7. Then the left exhaust duct 2 and the right exhaust duct 3 on the left and right sides of the oven body 1 simultaneously exhaust air to extract the gas inside the oven body 1, so that the airflow inside the oven body 1 is always in a flowing state, and the flowing airflow brings the toxic and explosive gases out of the oven; at the same time, because the fresh air is dispersed under the action of the spoiler component 9 and the flow-leveling component 10, the airflow inside the oven body 1 can flow completely, preventing toxic and explosive gases from accumulating inside the oven body 1, and effectively discharging toxic and explosive gases to ensure safe production.

[0029] In addition, the air intake volume of the air intake duct 4 is smaller than the air outlet volume of the two exhaust ducts, so that the interior of the oven body 1 is in a slightly negative pressure state, thereby preventing toxic and explosive gases from escaping to the outside of the oven.

[0030] Furthermore, a plurality of air inlets are provided on the top side of the oven body 1, preferably two air inlets, and both of the two air inlets are connected to the air inlet duct 4, that is, the fresh air transported by the air inlet duct 4 enters the interior of the oven body 1 from the two air inlets, thereby realizing the pre-dispersion of the fresh air and improving the dispersion effect of the fresh air.

[0031] Furthermore, two spoiler components 9 are provided, and the two spoiler components 9 are arranged under the two air inlets in a one-to-one correspondence, so as to disperse the fresh air introduced into the two air inlets.

[0032] In a specific embodiment, refer to Figure 5 and Figure 6 The spoiler assembly 9 includes two support plates 91 arranged opposite to each other and a plurality of spoiler plates connected between the two support plates 91. The plurality of spoiler plates are arranged at intervals. The support plates 91 are connected and installed to the inner top wall of the oven body 1, and a first spoiler hole 92 is arranged on the support plate 91. When the fresh air blown out from the air inlet enters between adjacent spoiler plates, part of the airflow will escape from the first spoiler hole 92, thereby realizing partial dispersion of the fresh air.

[0033] The spoiler includes an arc plate 93 and straight plates 94 connected to both sides of the bottom of the arc plate 93. The straight plate 94 extends in a direction away from the support plate 91. A plurality of second spoiler holes 95 are provided on the straight plate 94. The curvatures of the plurality of arc plates 93 are different, and the inclination directions of the plurality of straight plates 94 are different. When the fresh air blows on the arc plate 93, it will be guided along the arc surface of the arc plate 93. Since the curvatures of the arc plates 93 of the plurality of spoilers are different, the fresh air is guided to be blown out in different directions, thereby achieving further dispersion of the fresh air. In addition, a portion of the fresh air enters the support plate after being guided by the arc plate 93, and is blown out through the second spoiler holes 95 on the support plate, thereby achieving dispersion of the portion of the fresh air.

[0034] Specifically, refer to Figure 3 There are five arc-shaped plates 93. In the spoiler assembly 9 on the left, three arc-shaped plates 93 on the left are bent to the left, and two arc-shaped plates 93 on the right are bent to the right, and the curvatures of the bending are different; the spoiler assembly 9 on the right is symmetrically arranged with the spoiler assembly 9 on the left.

[0035] In a specific embodiment, refer to Figure 2-Figure 4 and Figure 7 The uniform flow component 10 includes a uniform wind plate 101 connected to the inner wall of the oven body 1. The uniform wind plate 101 is horizontally arranged, and a plurality of uniform wind holes 102 arranged in a uniform rectangular array are opened on the uniform wind plate 101. The fresh air dispersed by the spoiler component 9 is evenly dispersed from the uniform wind holes 102, thereby improving the dispersion effect of the fresh air.

[0036] In some embodiments, a wind knife assembly 11 is provided at the lower part of the oven box 1, and the wind knife assembly 11 includes two relatively arranged wind knife shells, and the wind knife shells are provided with wind knife openings. A wind cavity is provided in the wind knife shell, and the wind cavity is connected with a pipeline of an external air source through an air duct joint, so that the wind knife openings blow air into the oven box 1. Since the two wind knife openings are facing the middle of the oven box 1, the toxic and explosive gases on the surface of the coated electrode 7 are blown to the middle of the oven, so that the toxic and explosive gases are more concentrated, making it more convenient for the left exhaust duct 2 and the right exhaust duct 3 to extract the toxic and explosive gases.

[0037] In some embodiments, an observation window 5 is provided on the side wall of the oven body 1, through which the internal conditions of the oven can be observed at any time.

[0038] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
