Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a water tank used for washing a band-shaped member such as a band-shaped storage battery electrode plate, particularly a slit on the outlet side thereof. This invention relates to improvements in seal structure.

Structure of conventional example and its problems A band-shaped electrode plate for a nickel-cadmium storage battery is subjected to chemical conversion treatment and subsequent water washing treatment by passing it through a chemical conversion tank and a water washing tank, respectively.

At this time, the chemical conversion tank and the washing tank were provided with a sealing structure on each side of the tank so that the chemical conversion liquid and washing water contained therein would not leak out from the introduction and outlet portions of the strip member.

A typical water tank and the seal structure of the inlet and outlet parts are shown in FIG. That is, a strip member 2, in this case a strip plate, is introduced into a pair of opposing wall surfaces of a square or rectangular water tank 1,
An introduction side slit 3a and an output side slit 3b are provided for leading out the water, and the strip-shaped electrode plate is passed through the slits 3a and 3b to enter and exit the water tank 1. The slits 3a and 3b here were sealed by a pair of flexible band-like tongues 4a and 4b fixed to the tank wall and whose tips were in contact with each other.

However, in the case of such a slit seal structure, due to the orientation of the band-like tongues 4a and 4b, there is no problem at the introduction side slit 3a of the band-like member, but when the band-like member 2 is led out from the outlet-side slit 3b, there is no problem. There was a problem with the liquid leaking out as well.

As shown in an enlarged view in FIG. 2, as the band member 2 moves in the direction of the arrow, liquid or This is because water is drawn in and as the strip member 2 moves, it passes between the tongues 4a and 4b and leaks out to the outside.

Therefore, a pair of rubber rollers 5 shown in FIG.
It has been proposed to arrange rollers 5a and 5b in the tank 1 so as to press them against each other, and to close the space between the tank wall 6 and the rollers 5a and 5b with band-like tongues 7a and 7b.

In this structure, the rollers 5a and 5b are in close contact with the strip member 2, and it is possible to prevent water from being drawn in and leaking out when the member 2 is led out. It is necessary to maintain high accuracy, and if this is not maintained sufficiently, there is a problem that liquid may leak from the loose contact between the rollers or the belt-like member 2 may meander, resulting in worse results.

Purpose of the invention The present invention solves the drawbacks of such conventional examples,
The purpose is to effectively prevent liquid leakage from the slit on the outlet side of the water tank.

Structure of the Invention For this purpose, in the present invention, two L-shaped fixed frames provided in the tank and the inner wall surface of the tank around the slit are in contact with each other in a compressed state, and the surfaces where the opposing surfaces contact each other are non-porous. It is characterized by a pair of prismatic blocks made of resin sponge or rubber, and these prismatic blocks improve leakage from the outlet slit.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIGS. 4 and 5.

In the figure, 8a and 8b are L-shaped fixed frames provided in the tank 1 in a state close to the outlet side slit 3b, and these frames 8a and 8b and the tank wall 6 around the slit
Synthetic rubber prismatic blocks 9a and 9b are in contact with these in a compressed state between them, and the mutually facing surfaces 1
0a and 10b are arranged in contact with each other.

When the strip member 2 passes between the blocks 9a and 9b and is led out of the tank, as shown in FIG. Leakage was successfully suppressed.

That is, an elastic repulsive force acts on the rubber prismatic blocks 9a, 9b when they are fixed in a compressed state between the fixing frames 8a, 8b and the tank wall 6.
When the strip member 2 is forcibly passed between the blocks in the direction of the arrow in a pressed state, repulsive forces act in the X and Y directions, causing liquid to flow between the block and the strip member and between the block and the tank wall. It becomes denser and can suppress leakage.

Of course, instead of being made of rubber, the blocks 9a and 9b may be made of resin sponge with non-porous surfaces to obtain the same effect as when made of rubber.

Therefore, by sealing the outlet-side slit in this way to prevent liquid leakage, there is an advantage that the amount of liquid in the tank can be kept constant at all times, and the subsequent drying process can be easily performed.

Effects of the Invention In such a structure of the present invention, the prismatic block is
Since it is fixed between the L-shaped fixed frame provided in the tank and the inner wall surface of the tank around the slit, it is easy to improve the accuracy of the parallelism and perpendicularity of the pair of blocks, and it is possible to improve the accuracy of the parallelism and perpendicularity of the pair of blocks. Since deterioration in accuracy can be reduced, there is an advantage that meandering does not occur when the band-shaped member is passed through.
