Description

Technical Field

[0001] The utility model relates to the field of capacitor processing equipment, in particular to an impregnation tank device with a liquid control function. Background Art

[0002] The capacitor impregnation production line is a device used for the impregnation treatment of capacitor workpieces. It has the functions of improving the mechanical strength and insulation strength of the workpieces, as well as moisture-proof, mildew-proof, and noise reduction. In the electrolytic capacitor impregnation process, the workpiece containing the liner paper needs to be immersed in the impregnation tank device, immersed in electrolyte, and then dried. The above "immersion" and "drying" processes are repeated many times so that the substances in different electrolytes can be better absorbed by the liner paper.

[0003] However, the existing impregnation tank device has the following defects:

[0004] (1) The existing immersion tank device includes a tank A for immersing workpieces and a tank B for detecting the overflow of electrolyte in tank A. The existing air control liquid flow process is complicated. A float is set to detect the overflow of tank A. The float is connected to tanks A and B through a pipeline. Due to the large volume of the float, the float needs to float up to detect the overflow. When tank A is full of liquid and overflows into tank B, a lot of liquid needs to overflow to make the float in tank B float up, so as to detect the overflow of tank A and control the amount of electrolyte injected into tank A.

[0005] (2) In order to save electrolyte, the electrolyte recovered from tank B will be returned to tank A for the vacuum impregnation process of the workpiece. However, when tank A is detected to be overflowing, a certain degree of impregnation reaction has already occurred in tank A, resulting in a decrease in the concentration of the electrolyte overflowing into tank B. In the subsequent recycling process, when the electrolyte collected in tank B is returned to tank A, the concentration of the original solution in tank A will be diluted, reducing the impregnation quality. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model aims to provide an impregnation tank device with a liquid control function.

[0007] The purpose of the utility model is achieved by adopting the following technical scheme: an impregnation tank device with a liquid control function, comprising a tank A for immersing workpieces, a tank B for recovering the overflowing liquid in the tank A, and a liquid level sensor for detecting the liquid at the bottom of the tank B; one of the edges on the top of the tank A is provided with an overflow notch, and the height of the other edges is higher than the height of the overflow notch; one of the edges on the top of the tank B is connected with the overflow notch, so that the overflowing liquid in the tank A flows into the tank B from the overflow notch; a mounting hole is provided in the bottom of the tank B, and the liquid level sensor is penetrated in the mounting hole, and when the impregnation liquid in the tank A overflows and flows into the tank B, the liquid level sensor located at the bottom of the tank B detects that the tank A is overflowing, and then stops the injection of the impregnation liquid into the tank A.

[0008] Furthermore, a liquid injection port is provided at the bottom of the A tank, and the liquid injection port is electrically connected to an infusion system through an infusion pipeline, and the infusion system is used to control the injection amount of the impregnation liquid in the A tank.

[0009] Furthermore, a valve switch is provided at the bottom of the B tank, and the valve switch is electrically connected to the infusion system through a recovery pipeline. The infusion system is used to control the recovery of the impregnation liquid in the B tank to flow into the A tank.

[0010] Furthermore, the valve switch is a pneumatic ball valve.

[0011] Furthermore, the liquid level sensor is a contact type liquid level sensor that is in direct contact with the liquid.

[0012] Furthermore, the impregnation tank device includes a vacuum tank chamber and a lifting cover, wherein the A tank and the B tank are both installed in the vacuum tank chamber, and the lifting cover is located above the vacuum tank chamber and is driven by the cover lifting mechanism to lift and lower the cover to seal or open the slot of the vacuum tank chamber.

[0013] Furthermore, the impregnation tank device also includes a vacuum device for evacuating the entire interior of the vacuum tank chamber, and the vacuum tank chamber is provided with a vacuum port.

[0014] Furthermore, there are two groups of A grooves and B grooves, which are all arranged in the vacuum chamber and share the same vacuum device.

[0015] Furthermore, the cover lifting mechanism includes a locking motor, a linkage shaft, a belt, and a pulley; the belt is strip-shaped, one end of the belt is fixed on the pulley, and the other end is fixed on the lifting cover; the pulley is sleeved on the linkage shaft, and the linkage shaft is linked to the locking motor; the locking motor rotates, driving the linkage shaft to rotate, and then the pulley fixed on the linkage shaft rotates synchronously, thereby tightening or loosening the length of the belt to realize the up and down lifting movement of the lifting cover.

[0016] Furthermore, the impregnation tank device also includes a lifting cover locking mechanism, which is arranged on both sides of the vacuum tank chamber. During vacuum impregnation, the lifting cover locking mechanism presses the lifting cover onto the vacuum tank chamber.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) The present application improves the overflow notch structure of grooves A and B and designs the position of the liquid level sensor, so that the entire liquid control structure is simpler and more direct. After the impregnation liquid in groove A overflows, it flows into the bottom of groove B and contacts the liquid level sensor, which can directly control the injection of the impregnation liquid in groove A. It has higher reaction sensitivity and higher impregnation quality, and can be used to replace the existing float ball liquid control method, so as to avoid the situation where a lot of liquid overflows from groove A before the float ball in groove B floats up, thereby avoiding delayed feedback of overflow of groove A.

[0019] (2) The present application uses the infusion system to cooperate with the injection port in the impregnation device to automatically realize the injection amount of the impregnation liquid in tank A, thereby improving the automation performance of the equipment and reducing manual work processes.

In order to improve the impregnation quality, some products need to be impregnated in a vacuum environment, and for this purpose, an automatically lifting cover 6 is designed to realize the vacuum of the impregnation process and improve the applicability and practicality of the product.

[0038] As a further preferred embodiment, the impregnation tank device further comprises a vacuum device 7 for evacuating the entire interior of the vacuum tank chamber 5 , and a vacuum port 71 is provided on the vacuum tank chamber 5 .

One impregnation device contains multiple groups of A tanks 1 and B tanks 2 with liquid control functions, and share the same vacuum device 7, which reasonably utilizes the spatial structure, can improve production efficiency and reduce production costs.

[0040] As a further preferred embodiment, the function of the cover lifting mechanism 8 is to lift the cover to seal the impregnation device. Therefore, any mechanism that can achieve the lifting function can be used in the present device, including but not limited to the lifting structure described below. The specific structure includes a locking motor (not shown in the figure), a linkage shaft, a belt, and a pulley; the belt is strip-shaped, one end of the belt is fixed on the pulley, and the other end is fixed on the lifting cover 6; the pulley is sleeved on the linkage shaft, and the linkage shaft is linked to the locking motor; the locking motor rotates, driving the linkage shaft to rotate, and then the pulley fixed on the linkage shaft rotates synchronously, thereby tightening or loosening the length of the belt to realize the up and down lifting movement of the lifting cover 6.

[0041] As a further preferred embodiment, the impregnation tank device further includes a lifting cover locking mechanism 9, which is arranged on both sides of the vacuum tank chamber 5.
