Abstract

The present invention relates to the technical field of drying equipment, and in particular to a combined drying equipment for the manufacture of electrolytic capacitors. The combined drying equipment for the manufacture of electrolytic capacitors includes a drying conveying component, an airway component, a drying component, a reflux component, and two flow-increasing components. The present invention can quickly and evenly heat and dry electrolytic capacitors on both sides, ensuring that the surfaces of the electrolytic capacitors can be evenly heated, avoiding uneven drying that may be caused by single-sided heating. At the same time, it provides a step-by-step temperature change, which helps to gradually adjust the temperature of the electrolytic capacitors and prevent material damage caused by excessive temperature changes. It also provides a tangential airflow to impact the main drying electrolytic capacitors, preventing the opposite heating airflow from counteracting the main drying airflow for drying and heating, causing excessive heat concentration and local damage to the electrolytic capacitors. It also reduces airflow resistance, improves hot air flow efficiency, reduces energy waste, improves energy utilization efficiency, and saves drying costs.

Description

Technical Field

[0001] The present invention relates to the technical field of drying equipment, and in particular provides a drying equipment combined with electrolytic capacitor manufacturing. Background Art

[0002] During the manufacturing process of electrolytic capacitors, the electrolyte or solid electrolyte needs to be dried under certain temperature and humidity conditions to ensure the performance and stability of the capacitor. The drying equipment used in the manufacture of electrolytic capacitors is a device used to dry the electrolyte or solid electrolyte in the electrolytic capacitor. It can ensure the quality stability of the electrolytic capacitor during the production process, reduce product quality problems caused by moisture or impurities, and quickly process the electrolyte or solid electrolyte, shorten the production cycle, and improve production efficiency. However, the existing drying equipment adopts a single-point direct air supply drying mode and is prone to single-point temperature concentration when performing transmission drying. As a result, the surface temperature of some electrolytic capacitors is too high, while the temperature of other parts is too low, resulting in uneven drying. At the same time, the direct hot air impact of a single point can easily lead to confusion in the hot air flow path, which in turn causes the hot air to be unable to fully cover the surface of the capacitor, further affecting the drying uniformity.

[0040] For example, in one embodiment, lifting slots are provided at both ends of the hollow cavity 23, and lifting doors are provided in the lifting slots. A filter is provided in the downwind funnel 114.

[0041] For example, in one embodiment, when the electrolytic capacitors need to be dried, the lifting door is opened, and a plurality of electrolytic capacitors are placed in two rows on the top surface of the capacitor conveyor belt 14, and then the conveying motor 12 is started to allow the plurality of electrolytic capacitors to enter the hollow cavity 23 and be transported to the bottom of the drying assembly 30. Then, the lifting door is closed, and the heating generator 32 is started to generate a uniform high temperature in the installation cavity 33, and then the four air pumps 24 are started synchronously to generate a push airflow, and the push airflow is made to flow along the air inlet 233, the connecting pipe and the inlet. The air connection port 332 enters into the installation cavity 33, and generates heat exchange to form a main drying airflow that flows out along the main drying slot 331, and heats and dries the electrolytic capacitor below.

[0042] At the same time, the counter-heating airflow will counteract the main drying airflow, forming a counter-flow. Due to the higher velocity and flow rate of the main drying airflow, the counter-flow will flow downward from between the two flow-increasing components 50 to the downwind funnel 114. Since the downwind funnel 114 is provided with a filter, the counter-flow will filter out moisture through the filter before entering the return chamber 111. It will then enter the return air duct 221 through the return port 224, and then enter the two return elements 45 through the first and second diverter pipes 222 and 223. Part of the counter-flow will then flow out through the return outlet slot 455, causing a step-by-step temperature change for the electrolytic capacitors that have not yet undergone the main drying process and those that have already undergone the main drying process. At the same time, another part of the counter-flow will impact the two return flow guide plates 453, causing the two guide shafts 452 to rotate and open, so that the other part of the counter-flow will be guided by the two return flow guide plates 453 to form an inclined tangential airflow to impact the main drying electrolytic capacitor, preventing the counter-heating airflow from counteracting the main drying airflow for drying and heating, causing excessive heat concentration, resulting in local damage to the electrolytic capacitor, and reducing airflow resistance, improving hot air flow efficiency, reducing energy waste, improving energy utilization efficiency, and saving drying costs.

[0043] In addition, by rotating the adjusting hand wheel 110, the adjusting shaft 119 can be rotated, the first bevel gear can be rotated, the second bevel gear 441 can be rotated, the two threaded rods 44 can be rotated, and the two reflux control cross bars 43 can be slid along the four sliding columns 42, thereby adjusting the positions of the two reflux elements 45, and changing the size and position of the counter-flow and tangential airflow, thereby effectively controlling the heating intensity of the electrolytic capacitor and the intensity of the step temperature change.

[0044] For example, in one embodiment: when it is necessary to reduce the drying degree, the regulating cylinder 531 is started, so that the output shaft of the regulating cylinder 531 retracts, so that the lever 532 moves upward along the longitudinal mounting slide groove 514, and the middle part of the elastic trigger belt 536 is pulled upward, so that the two heating mounting rotating rods 533 rotate, so that the two heating mounting slide rods 534 and multiple heating wires 535 rotate and move upward, so that the supporting rotating rod 545 follows and moves, so that the two diversion guide plates 542 follow and rotate and open along the two first diversion rotating shafts 541, so that the counter-flow enters the gap of the downwind funnel 114 and rises, so that the counter-flow can quickly enter the downwind funnel 114 and then enter the return chamber 111, thereby reducing the contact time of the counter-flow with the electrolytic capacitors being dried mainly, and reducing the drying degree of the electrolytic capacitors. At the same time, the diversion guide plate 542 will no longer support the linkage bar 549, so that the two vertical collecting plates 543 will fall along the longitudinal installation slide groove 514, so that the cross-sectional area blown out by the flow-increasing fan 52 will increase, and the flow rate of the opposite heated air flow will decrease, further reducing the contact time between the counter-flow airflow and the main drying electrolytic capacitor, and reducing the degree of drying of the electrolytic capacitor.
