Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a vertical plate conveyor for conveying cut plates for pickling equipment.

(Prior Art) Conventionally, as a conveyor for pickling equipment that conveys cut plates in an upright position, a roller conveyor composed of rollers made of acid-resistant lining has been used. However, due to the high line pressure, the life of the roller is short and the lining cost increases. As a way to solve this problem, it was considered to send the cut plates in an upright position using a plate conveyor that continuously arranges the slats. However, in the case of flat slats, the acid solution sprayed during pickling could damage the cut plates. It spreads onto the slats, runs along the inner wall of the pickling tank and spills onto the slats, flows through the slats and leaks out of the tank on both sides, causing trouble to the slat moving device and adversely affecting the pickling quality. The drawback was that the amount of processing solution consumed increased and the pickling cost increased.

(Problems to be solved by the invention) An attempt is made to solve the problems of the prior art and provide a slat structure that prevents the sprayed acid solution from leaking out of the tank even if it is on the slats. It is something to do.

(Devised solution) A slat with a cutting plate holder attached to the center of the tank is raised diagonally above the cutting plate holder on both sides of the cutting plate holder, and both ends are led out of the tank. By doing so, the acid solution sprinkled on the slats can be prevented from leaking out of the tank through the slats.

(Example) One example will be described below with reference to the drawings. In FIG. 1, 1 is a pickling tank divided into upper and lower parts. 2 is a cut plate strip, which is conveyed horizontally in an upright position by a plate conveyor 3. A pedestal 6 made of acid-resistant lining is provided on the plate conveyor 3, and the cut plate strip 1 rests on this and is further guided by side guide rollers 13 made of acid-resistant lining on both sides to be conveyed in the pickling tank 1 in an upright position. be done.

The plate conveyor 3 has a pedestal 6 mounted at the center of the pickling tank 1, and rises obliquely upward from the skid 6 on both sides of the pedestal 6, with both ends overhanging the outside of the tank 1.
It is constructed by alternately arranging slats 4 made of acid-resistant lining and slats 5 made of acid-resistant lining having a notch 8 in the center and leaving only both sides of the slat 4.

And each slat 4, 5 of the plate conveyor 3
The rising portion diagonally upward moves through the gap 14 between the divided portions of the pickling tank 1 and circulates endlessly.

Acid liquid spray nozzles 7 are provided inside the tank 1, and are provided on the left and right sides of the cut plate strip 2 so as to be able to spray from both sides thereof.

Figures 4 and 5 show another embodiment of the slat. In this case, an opening 9 is provided in the center of the slat 4a, through which the sprayed acid solution falls. 1
0 is a reinforcing rib provided at the lower part of the slat 4a. In this case (FIGS. 4 and 5), the plate conveyor is entirely composed of the slats 4a.

Each of the slats 4, 5 or 4a has rollers 11 attached to the lower portions of both sides projecting outward from the tank 1, and rolls on rails 12.

(Effect) As described above, the slat with the cut plate holder 6 attached to the central position inside the tank 1 is raised diagonally above the cut plate holder on both sides, and the ends are extended outside the tank. Therefore, even if the sprayed acid solution travels along the cut plate strip 2 onto the slats, or travels down the wall of the pickling tank 1 and onto the slats, there is almost no leakage through the slats to the outside of the tank. Therefore, consumption of the acid solution is suppressed, and the cost for pickling cut plates can be reduced. Therefore, there is no problem in the operation of the slat moving device, so the conveyance of cut plates during pickling can be carried out smoothly, and this has a great effect in that products with a good pickling finish can be obtained.
