Abstract

PURPOSE:To prevent leakage from an outlet side slit of a tank by providing a pair of square pillar blocks made of rubber etc. having no pore on the surface that are in contact with two L-shaped fixing frame in the tank and with the tank wall around a slit in compressed condition and having facing surfaces in contact to each other. CONSTITUTION:Slits for introducing and leading out a belt-like member 2 are provided on a pair of facing tank walls 1. At the same time, the inlet side slit is sealed by a pair of beltlike tongues having tips in contact to each other and provided in the tank. The outlet side slit 3b is in contact with L-shaped fixing frames 8a, 8b provided in the tank and tank wall 6 around the slit in compressed state, and sealed by a pair of square pillar blocks 9a, 9b made of resin sponge or rubber having no pores on the surface and having opposite faces in contact with each other. Elastic repulsive force acts on the square pillar blocks when they are fixed in compressed state between fixing frames 8a, 8b and tank wall 6, and components of the repulsive force act in the directions X, Y. Thus, leakage can be suppressed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a water tank used, for example, when a band-shaped member such as a band-shaped storage battery electrode plate is passed through and washed with water, and in particular, improvement of the sealing structure thereof. It is related to.

Conventional Structure and Problems The band-shaped electrode plates for nickel-cadmium storage batteries are subjected to chemical conversion treatment and subsequent water washing treatment by passing them 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.

The typical water tank and the seal structure of the introduction and outlet parts are the first
As shown in the figure. 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 aquarium 1.

An inlet side slit 3a and an outlet side slit 3b are provided for the tank to be led out, and a band-shaped electrode plate is passed through the slits 3a and 3b to enter and exit the aquarium 1. The sulins 3a and 3b here were sealed with a pair of flexible band-like tongues 4a and 4b whose tips were in contact with each other and which were fixed to the tank wall.

However, in the case of such a slit seal structure, due to the orientation of the strip tongues 4a and 4b, there is no problem with the introduction side slit 3a of the strip member, but with the outlet side slit 3b, when the strip member 2 is led out, Along with this, there was also the problem that liquid leaked out.

As shown in an enlarged view in FIG. 2, as the band member 2 moves in the direction of the arrow, liquid or Water is drawn in, and as the strip member 2 moves, the tongue piece 4a
, 4b and leaks to the outside.

Therefore, in order to prevent the liquid from leaking from the outlet side sulin) 3b, a pair of rubber rollers sa and sb shown in FIG. , 5b was proposed in which the gap between the two is closed with band-like tongue pieces 7a and 7b.

In this structure, the rollers sa and sb are in close contact with the strip member 2,
Although it was possible to prevent water from drawing in and leaking out when the member 2 was drawn out, it was necessary to maintain the parallelism, parallelism, and perpendicularity of the rollers 5a and 5b at a high precision of 1. If this is not maintained, 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 even worse results.

OBJECTS OF THE INVENTION The object of the present invention is to solve the above-mentioned drawbacks of the conventional example and to effectively prevent liquid leakage from the outlet side slit of the water tank.

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

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be explained with reference to FIGS. 4 and 6.

In the figure, sa and sb are L-shaped fixed frames provided with eaves inside the tank 1 in a state close to the outlet side sulin) 3b, and this frame s
A, sb and the tank wall 6 around the slit, synthetic rubber prismatic blocks 9a, 9b are in contact with these in a compressed state, and mutually facing surfaces 10a.

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 and 9b when they are fixed in a compressed state between the fixed frames 8a and ah and the tank wall 6, and the strip member 2 is moved between the blocks. X
A repulsive force acts in the direction and the Y direction, making the space between the block and the strip member and between the block and the tank wall liquid-tight, thereby suppressing liquid leakage.

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

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

Effects of the Invention In this configuration of the present invention, the prismatic block is fixed between the L-shaped fixed frame provided in the tank and the tank wall around the slit, so the parallelism and perpendicularity of the pair of blocks are fixed. It is also easy to increase the precision of the strips, and deterioration of these precisions due to embrittlement can be reduced, so there is an advantage that meandering does not occur when the strip member is passed through.
