Description

Technical Field

[0001] The utility model relates to the technical field of industrial ovens, in particular to an air blast structure of a capacitor aging oven. Background Art

[0002] Industrial ovens are made of angle steel and thin steel plates. In addition, the box is strengthened, the outer surface is painted, and the outer shell and the inner tank are filled with aluminum silicate fiber to form a reliable insulation layer. Industrial ovens have a wide range of applications and can dry various industrial materials. They are universal drying equipment.

[0003] In the capacitor production industry, capacitors need to be placed in an oven for aging, and the heating and baking effect of the oven will directly affect the aging quality of the capacitors. For example, the Chinese patent document with the publication number CN116793031A discloses a multi-element drawer-type capacitor industrial baking device, which discloses the following content: the baking oven includes a baking oven body, a capacitor baking mechanism, a door opening mechanism and a blower mechanism, the capacitor baking mechanism is connected to one side of the door opening mechanism and is connected to the baking oven body, the door opening mechanism is respectively connected to the capacitor baking mechanism and the baking oven body, the blower mechanism is arranged on the baking oven body, the capacitor baking mechanism includes a capacitor baking layer, a heater, a door body and a charging brush plug, the capacitor baking layer and the heater are both arranged in the baking oven body, the door body is connected to the door opening mechanism, the charging brush plug is arranged on the inner side of the baking oven body, the blower mechanism includes a first blower and a second blower, the first blower and the second blower are both connected to the baking oven body, an air inlet box is arranged on the top of the baking oven body, and a plurality of air inlet holes are arranged on the bottom. In this way, the first blower and the second blower blow air into the oven body, and the heat generated by the heater is evenly distributed everywhere along with the airflows blown out by the first blower and the second blower, thereby accelerating the efficiency of capacitor heating.

[0004] However, the existing baking device has the following deficiencies in actual use: the first blower and the second blower inhale the external wind through the air inlet box and the air inlet hole, and then pressurize the wind and blow it into the capacitor baking layer through the air vents, so that the heat emitted by the heater is evenly blown into every corner of the baking layer. That is, when the existing baking device heats and bakes the capacitor, the first blower and the second blower continuously blow the external gas into the capacitor baking layer. However, since the external gas is room temperature gas, the continuous blowing of room temperature makes it difficult for the temperature in the capacitor baking layer to quickly rise to the required value, resulting in too low heating efficiency; secondly, after the capacitor is aged, the existing baking device cannot quickly cool down the capacitor and can only cool it naturally, resulting in a too long capacitor aging cycle. Therefore, in order to solve the above technical problems, the capacitor aging oven blast structure of the present application is proposed. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0032] like Figures 1 to 5As shown, a capacitor aging oven air blowing structure 10 includes a box body 100 and an air supply assembly 200, an air inlet pipe 110 and an air outlet pipe 120 are respectively arranged on both sides of the box body 100, and a switch valve 130 is arranged on the air inlet pipe 110 and the air outlet pipe 120. A heater 140 is respectively arranged on the inner side of the box body 100 near the air inlet pipe 110 and the air outlet pipe 120. The air supply assembly 200 includes a circulating fan 210, a circulating air duct 220 and an exhaust fan 230. The circulating air duct 220 is arranged on the rear side of the box body 100, and both ends of the circulating air duct 220 are connected to the box body 100, and the two ends of the circulating air duct 220 are respectively arranged toward the two heaters 140, the circulating fan 210 is arranged on the circulating air duct 220, and the exhaust fan 230 is arranged on the end of the air outlet pipe 120 away from the box body 100.

[0033] It should be noted that the box 100 is a rectangular parallelepiped structure, and a door panel is provided on one side thereof. After opening the door panel, the capacitor can be placed in the box 100. The air inlet pipe 110 is installed on one side of the box 100, and the air outlet pipe 120 is installed on the other side of the box 100. The air inlet pipe 110 and the air outlet pipe 120 are both connected to the box 100. An electrically controlled switch valve 130 is installed on the air inlet pipe 110 and the air outlet pipe 120 to control the opening and closing of the air inlet pipe 110 and the air outlet pipe 120 by using the switch valve 130. Two heaters 140 are both installed in the box 100, and one of the heaters 140 is arranged close to the air inlet pipe 110, and the other heater 140 is arranged close to the air outlet pipe 120. The circulating air duct 220 is fixedly installed on the back side of the box 100, and both ends of the circulating air duct 220 are connected to the box 100, wherein the two ends of the circulating air duct 220 are respectively arranged toward the two heaters 140. The circulation fan 210 is fixedly mounted on the circulation air duct 220. The exhaust fan 230 is fixedly mounted on one end of the air outlet duct 120 away from the box 100. In this way, after the heater 140 is started, as the circulation fan 210 is started for a period of time, after the switch valves 130 on the air inlet duct 110 and the air outlet duct 120 are closed, the circulation fan 210 drives the gas in the box 100 to circulate through the two heaters 140, so that the temperature in the box 100 can be quickly raised. When the capacitor is aged, the circulation fan 210 stops, and then the two switch valves 130 are opened and the exhaust fan 230 is started. In this way, the external gas enters the box 100 from the air inlet duct 110 and is then discharged through the air outlet duct 120, so that the temperature in the box 100 can be quickly reduced. Compared with the existing oven device, the capacitor aging oven blast structure 10 of the present application can achieve rapid heating and rapid cooling.

[0034] like Figure 3 As shown, in one embodiment, a partition net 150 is respectively disposed on the two inner side walls of the box body 100 , and the heater 140 is located between the inner side wall of the box body 100 and the partition net 150 .

[0035] It should be noted that the gas enters the box 100 through the partition 150, or flows out through the partition 150, so that the gas can be evenly distributed in the box 100 under the action of the partition 150, so that the temperature in each place of the box 100 is uniform.

[0036] like Figure 3 As shown, in one embodiment, a plurality of mesh holes 151 are formed on the partition net 150. For example, the mesh holes 151 are circular hole structures, so that the gas is evenly distributed in the box body 100.

[0037] In one embodiment, the circulating air duct 220 faces the inner wall of the box body 100 and between the partition nets 150. In this way, it is ensured that the gas fully flows through the heater 140 to be heated, and under the action of the circulating air duct 220, the gas can be heated quickly.

[0038] like Figure 4 As shown, in one embodiment, the heater 140 includes two brackets 141 and three heating tubes 142 . The two brackets 141 are spaced apart on the inner wall of the box body 100 , and the three heating tubes 142 are respectively connected to the two brackets 141 along the vertical direction.

[0039] It should be noted that in order to allow the gas to be heated by the heater 140. Therefore, the heater 140 is configured as a structure in which three heating tubes 142 are suspended by a bracket 141. Specifically, the two brackets 141 can be installed on the inner wall of the box 100 by welding, wherein a gap is provided between the two brackets 141. Then the three heating tubes 142 are respectively installed on the two brackets 141, and the three heating tubes 142 are spaced apart in the vertical direction. In this way, when the gas flows through each heating tube 142 from the partition 150, it can be fully heated, thereby effectively improving the heating efficiency of the gas in the box 100.

[0040] like Figure 1 As shown, in one embodiment, a pressure relief hole 160 is provided on the rear side of the box body 100. It should be noted that as the gas in the box body 100 is circulated and heated, the gas will expand. In order to prevent the box body 100 from bursting, a pressure relief hole 160 is provided on the back side of the box body 100. In this way, when the gas expands, the pressure can be released through the pressure relief hole 160, thereby improving safety.

[0041] like Figure 1As shown, in one embodiment, a plurality of box bodies 100 are provided, and each box body 100 is arranged in sequence along the vertical direction. A plurality of circulating fans 210 and circulating air ducts 220 are provided, and each circulating air duct 220 is respectively provided on each box body 100, and each circulating fan 210 is respectively provided on each circulating air duct 220. The air supply assembly 200 also includes an exhaust duct 240, and one end of each air outlet duct 120 away from the box body 100 is connected to the exhaust duct 240, and the exhaust fan 230 is provided on the top of the exhaust duct 240.

[0042] It should be noted that, due to the limited space of a single box 100, in order to increase the aging yield of the capacitor, a plurality of boxes 100 are provided so that each box 100 is spaced apart in the vertical direction. For example, three boxes 100 are provided, and the three boxes 100 are equally spaced in the vertical direction. Further, a circulation duct 220 is installed on the back side of each box 100, and then a circulation fan 210 is installed on each circulation duct 220. Further, the air outlet of the air outlet duct 120 is connected to the exhaust duct 240. The exhaust fan 230 is installed on the top of the exhaust duct 240, so that the exhaust fan 230 controls the exhaust of gas in multiple boxes 100 at the same time. In one embodiment, each box 100 can be mounted on a rack for fixing.

[0043] like Figure 1 As shown, in one embodiment, the air supply assembly 200 further includes an air inlet pipe 250 , and one end of each air inlet pipe 110 away from the box body 100 is connected to the air inlet pipe 250 .

[0044] It should be noted that each air inlet pipe 110 is connected to the air inlet pipe 250 , so that the air inlet pipe 250 uniformly supplies air to the box 100 , which can ensure balanced heating in each box 100 .

[0045] like Figure 1 As shown, in one embodiment, a filter box 260 is provided at the top of the air inlet pipe 250. Thus, by installing a filter box 260 at the inlet, wherein filter cotton is installed in the filter box 260, the external air is filtered by the filter cotton to prevent dust and other impurities from entering the box body 100.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
