Abstract

PURPOSE:To effectively remove a stuck substance without damaging a conveyor belt. CONSTITUTION:When conveyor belts 9 and 11 are run to the return side, the belts are run through a washing tank 19 in which washing liquid 18 is stored and immersed in the washing liquid 18 by a stuck substance peel roll 20, and bending is applied thereon. This constitution causes effective peel of a stuck substance without damaging the conveyor belts 9 and 11.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art A conventional conveyor belt cleaning device is shown in FIG.
As shown in Fig. 6, the scraper 2 is placed in contact with the conveyor belt 1 so that the scraper 2 scrapes off the deposits on the conveyor belt 1 directly, or, as shown in Fig. 6, it is cleaned toward the conveyor belt 1. The cleaning liquid 4 such as water is sprayed from the nozzle 3 to wash off the deposits on the conveyor belt 1, and then the cleaning liquid 4 attached to the conveyor belt 1 is cut off by the water draining roller 5.

Reference numeral 6 is a pressing roller.

[0004]

However, the above-mentioned conventional conveyor belt cleaning device has the following problems.

That is, in the case of using the scraper 2 shown in FIG. 5, the conveyor belt 1 is worn and damaged, so that the conveyor belt 1 must be periodically replaced.

Further, the one using the cleaning nozzle 3 of FIG.
The cleaning effect on the conveyor belt 1 is not sufficient.

In view of the above situation, it is an object of the present invention to provide a conveyor belt cleaning device capable of effectively removing deposits without damaging the conveyor belt.

[0008]

According to the present invention, a cleaning tank is provided on the return side of a conveyor belt, through which the conveyor belt can pass, and a cleaning liquid can be stored therein. The present invention relates to a conveyor belt cleaning device, characterized in that it is provided with a belt for bending and provided with an adherent peeling roll for immersing the bent portion of the conveyor belt in a cleaning liquid.

[0009]

The operation of the present invention is as follows.

When the conveyor belt comes to the return side, the conveyor belt is passed through a cleaning tank in which the cleaning liquid is stored, and is immersed in the cleaning liquid by an adhering material peeling roll and is bent, whereby the conveyor belt is damaged. The deposit is effectively peeled off without being removed.

[0011]

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show a first embodiment of the present invention, which is applied to a steeply inclined conveyor 7.

An endless upper conveyor belt 9 hung on a plurality of upper sheaves 8 and an endless lower conveyor belt 11 hung on a plurality of lower sheaves 10 are fed to each other on the feeding side 1.
By arranging at least a part of 2 to overlap,
A product 14 is sandwiched between the overlapping portions 13 so that a steep slope can be carried (the case of carrying vertically is shown in the figure).

Reference numeral 15 is a return side of the conveyor belts 9 and 11, and 16 is a clamp roller for holding the upper and lower conveyor belts 9 and 11 in the overlapping portion 13.

In the present invention, the conveyor belt 9,
On the return side 15 of 11, the conveyor belts 9 and 11 are passed through the guide rollers 17 on the inlet side and the outlet side, and a cleaning tank 19 capable of storing a cleaning liquid 18 such as water is provided inside.

A guide roller 17 inside the cleaning tank 19 is also provided.
The conveyor belts 9 and 11 are bent at a position between and below the liquid surface of the cleaning liquid 18, and an adherent peeling roll 20 is provided to dip the bent portions of the conveyor belts 9 and 11 into the cleaning liquid 18.

Further, the cleaning tank 19 is provided with a cleaning liquid supply device 21 such as a cleaning liquid injection nozzle for supplying the cleaning liquid 18, a drainage outlet 22 is provided, and the drainage outlet 22 is provided.
A gutter-shaped drainage outlet 23 is connected to the drainage outlet 23, and a flow rate adjusting weir plate 24 is provided inside the drainage outlet 23 with a space.

Further, a stirring device 25 for the cleaning liquid 18 such as a cleaning liquid injection nozzle is provided inside the cleaning tank 19, and the cleaning liquid 18 is applied at high pressure toward the conveyor belts 9 and 11.
For removing deposits such as a cleaning liquid spray nozzle for spraying
To provide.

In this case, the stirring device 25 and the adhered substance removing device 26 are also used as the cleaning liquid supply device 21 (of course, they may be provided separately).

Next, the operation will be described.

Upper conveyor belt 9 of steep slope conveyor 7
The lower conveyor belt 11 and the lower conveyor belt 11 are moved so that the overlapping portions 13 are in the same direction as each other, and the transported article 14 is supplied onto the lower conveyor belt 11.

Since the article to be conveyed 14 is held between the upper and lower conveyor belts 9 and 11, it can be conveyed even on a steep slope.

At this time, if the upper and lower conveyor belts 9 and 11 are wet, the powder of the article to be conveyed 14 adheres to the conveying surfaces of the upper and lower conveyor belts 9 and 11.

Therefore, a cleaning tank 19 in which the cleaning liquid 18 is stored in advance is provided at a portion immediately after the conveyor belts 9 and 11 are turned from the sending side 12 to the returning side 15, and the conveyor belts 9 and 11 are provided inside the cleaning tank 19. And is guided by the guide roller 17 and the adhered substance peeling roll 20.

Then, the conveyor belts 9 and 11 are guided downward by the adhering substance peeling roll 20 and immersed in the cleaning liquid 18, and then bent by the adhering substance peeling roll 20.

By thus wetting and bending the conveyor belts 9 and 11, it is possible to effectively remove the deposits without damaging the conveyor belts 9 and 11.

At this time, by stirring the cleaning liquid 18 inside the cleaning tank 19 by the stirring device 25 such as a cleaning liquid jet nozzle, it is possible to prevent the adhered substances that have peeled off from settling on the bottom of the cleaning tank 19, and By supplying the cleaning liquid 18 into the cleaning tank 19 from the cleaning liquid supply device 21 such as a cleaning liquid injection nozzle, the cleaning liquid 18 overflows from the drainage outlet 22, and the cleaning liquid 18 is replaced.

The drainage discharged from the drainage outlet 22 is discharged from the trough-shaped drainage outlet 23 while the flow rate adjusting dam plate 24 properly adjusts the discharge amount or the discharge speed.

Further, by supplementarily injecting the high-pressure cleaning liquid 18 toward the conveyor belts 9 and 11 from the deposit removing device 26 such as the cleaning liquid ejecting nozzle, the cleaning effect can be made more complete.

FIG. 3 shows a second embodiment of the present invention, which has the same structure as that of the above embodiment except that a propeller type stirring device 25 is used. Obtainable.

FIG. 4 shows a third embodiment of the present invention, which has the same configuration as each of the above-mentioned embodiments except that a scraper is used as the adhering matter removing device 26, and has the same operation and effect. Obtainable.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and it is also possible to combine the embodiments, and other various changes may be made without departing from the gist of the present invention. Of course, it can be added.

[0033]

As described above, according to the conveyor belt cleaning device of the present invention, it is possible to obtain the excellent effect that the adhered substances can be effectively removed without damaging the conveyor belt.
