DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt cleaning device used for cleaning a belt of a belt conveyor.

[0002]

2. Description of the Related Art In a belt conveyor for conveying foods and the like, it is necessary to keep the belt clean for hygiene management. What is described in 282823 is known. In this belt cleaning device, a cleaning liquid is supplied to a cleaning tank in an overflow state, and a belt is linearly passed through the cleaning tank.

[0003] The washing liquid overflowing from the washing tank is collected by a large tank installed in a manner to receive the lower part of the washing tank.
After that, the water is circulated and supplied again into the cleaning tank by a pump or the like. Further, at a portion where the belt comes out of the cleaning tank, a nozzle for jetting clean water for finishing to the belt and a blower for blowing off the clean water adhered to the belt are provided.

[0004]

In the above-mentioned conventional belt cleaning apparatus, there is only one cleaning tank, and only one type of cleaning water can be used. Therefore, for example, when it is desired to perform two-stage or two-stage cleaning of preliminary cleaning and finishing cleaning, a plurality of belt cleaning devices having the same configuration are arranged side by side along the running direction of the belt. Was required, which led to an increase in the installation area.

[0005] If there is no room for a straight portion in a belt conveyor or the like, it is impossible to install a plurality of belt cleaning devices.
It was decided that a satisfactory cleaning effect could not be obtained. The present invention has been made in view of the above circumstances, and has been made capable of performing a multi-stage cleaning while preventing an increase in installation area, and performing satisfactory belt cleaning. It is an object of the present invention to provide a belt cleaning device that enables each cleaning water to be individually collected when using the same, thereby reducing the running cost by reusing them.

[0006]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the belt cleaning device according to the present invention, a plurality of cleaning tanks are provided in a plurality of stages vertically, and the belts of the belt conveyor can pass through the respective cleaning tanks in a sequential manner.

For example, this belt cleaning device is installed at a position near the upper and lower turn portions of the belt conveyor, so that the upper cleaning tank that allows the upper belt of the belt conveyor to pass therethrough and the lower belt of the belt conveyor that passes the lower belt. What is necessary is just to have a washing tank of the upper and lower two stages with the lower washing tank to be made. Therefore, the washing is repeated each time the belt passes through each washing tank, and the belt is finally finished to a satisfactory degree of washing. In addition, since the cleaning tanks are arranged so as to be stacked in a plurality of upper and lower stages, the installation area may be the same as the case where one cleaning tank is provided (that is, the conventional installation area). .

[0008] For this reason, even in the case where it is not possible to secure a sufficient linear portion in the belt conveyor, it is possible to wash the belt in a plurality of stages. The belt is not limited to a belt belt, but has a net structure in which chains are also woven in the width direction, and a ladder structure in which bars or rollers are provided at predetermined intervals. The link may be provided, or a link may be used as a main body, and a transport support plate may be attached to each link.

Further, the belt is first passed to the upper cleaning tank and then to the lower cleaning tank, or conversely, first passed to the lower cleaning tank and then to the upper cleaning tank. Passage is not limited at all. However,
In the washing tank installed at the top, it is preferable to have a structure in which the upper surface of the belt is opened upward.
When at least the uppermost cleaning tank is emptied and the belt cleaning device is not used, the belt on the upper side can be used as it is for carrying (passing) the article.

[0010] Therefore, the installation area of the belt cleaning device can be more effectively utilized. At the bottom of the bottom cleaning tank, a recovery tank is provided to receive the lower part of all the cleaning tanks, and the cleaning water flowing out of each cleaning tank is collected separately in this recovery tank. Separation of each washing water becomes possible by partitioning it as much as possible.

Therefore, turbidity, dilution, alteration, fouling, etc. of each washing water can be prevented, and each washing water can be reused as needed.
