Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an efficient water-washing type deposit removing device for a belt conveyor that transports powder and granules.

[0002]

[Prior art]

 Generally, when transporting powdered particles such as ores and coal on a belt conveyor, the conveyor belt on which the powdered particles, which are the transported objects, is moved in one direction, and the powdered particles are dropped downward via the head pulley. The conveyor belt used was an endless belt conveyor that became an endless return belt. However, the particles on the conveyor belt do not fall completely and return with the adhering material attached to the lower surface of the return belt, which may fall off in the middle and cause dust or malfunction of the belt conveyor. Was becoming.

In order to remove the deposits on the conveyor belt, as shown in FIG. 2, the washing water 15 is sprayed on the conveyor belt (return belt 2) by the nozzle 3 to blow off the deposits 1a. Is disclosed in JP-A-2-33025. That is, in order to remove the deposit 1a attached to the lower surface of the return belt 2, the spray nozzle 3 is arranged between the snubb pulley 8 and the first pressing roller 5, and the cleaning water emitted from the spray nozzle 3 is removed. The deposit 1a is removed by 15 and washed with water. In addition, the drainage rollers 4 are arranged at two places in contact with the lower surface of the return belt 2 downstream of the location where the adhered matter 1a is washed and washed, and the radiated cleaning water 15 is drained from the lower surface of the return belt 2 and then dried. This is a method of drying the lower surface of the return belt 2 with the cleaner 6.

A method of immersing the belt 2 in a water tank 12 as shown in FIG. 3 and removing the adhering matter 1a with a brush 13 is disclosed in Japanese Patent Laid-Open No. 58-113023, and as shown in FIG. A method is disclosed in Japanese Utility Model Laid-Open No. 55-20312, in which water is supplied to the surface of the return conveyor to cause the deposit 1a adhering to the surface of the belt to be hydrated and removed by a rotating brush.

[0005]

[Problems to be solved by the device]

 However, in the method disclosed in JP-A-2-33025, the supply port of the nozzle 3 is clogged and the water pulsates in the water supply pipe. Therefore, a flow rate adjusting valve is required for stable water supply. However, there was a problem that the equipment cost was high and maintenance was required.

Further, in the method disclosed in Japanese Patent Laid-Open No. 58-113023, the entire bend pulley 14 has to be immersed in the cleaning water 15 in the water tank 12, which makes it difficult to seal around the rotary shaft. There was also a problem that it was difficult to drain water because both sides of the belt got wet. The method disclosed in Japanese Utility Model Laid-Open No. 55-20312 has a problem that the sealing property and water retention property of the contact portion between the surface of the belt 2 and the water tank 12 become difficult.

An object of the present invention is to provide a water-washed type adhered substance removing device for a belt conveyor that solves the above problems.

[0008]

[Means for Solving the Problems]

 The present invention is directed to a belt-type water washing-type adhered matter removing device having a water draining roller 4, a dry cleaner 6 and a snubbing pulley 8. The belt conveyor is equipped with a bend pulley 14 so as to come into contact with the lower surface of the return belt 2 and the cleaning water 15 in the water tank 12.

[0009]

[Action]

 According to the present invention, the lower portion of the bend pulley 14 is brought into contact with the wash water 15 in the water tank 12 installed below the return belt 2, and the water attached to the pulley 14 is used as the belt 2 by utilizing the rotation of the bend pulley 14. It is possible to continuously carry it up quantitatively to the contact portion of the belt and to remove the deposit 1a on the return belt 2 over the entire surface of the belt contact portion to wash and drain it.

[0010]

【Example】

 An embodiment of the present invention will be described with reference to FIG. A device composed of a water tank 12 for storing the cleaning water 15 and a bend pulley 14 for supplying the cleaning water 15 to the return belt 2 is arranged just below the return belt 2 only between the snubbing pulley 8 and the draining roller 4. Set up.

By the bend pulley 14, the cleaning water 15 is quantitatively and continuously applied over the entire contact surface between the bend pulley 14 and the return surface of the belt 2 to wash off the deposit 1a and drain the bottom surface of the belt to remove a series of belts. Removal of deposits, washing with water and draining can be performed continuously and effectively. Next, if the existing draining roller 4 and the dry cleaner 6 are provided downstream thereof to drain and dry the return belt 2, the draining and drying of the belt is further completed. If the belt 2 is drained only by the bend pulley 14, the draining roller 4 and the dry cleaner 6 in the subsequent step may be omitted.

[0012]

[Effect of device]

 As described above, with the water-wash-type deposit removing device of the belt conveyor according to the present invention, the deposit 1a attached to the return belt 2 can be completely removed and the surface thereof can be continuously washed and drained. The equipment is simple, convenient and efficient. On the other hand, since only part of the bend pulley 14 is immersed in the cleaning water 15 in the water tank 12, it is not necessary to seal the circumference of the rotary shaft of the bend pulley 14 and the facility cost can be reduced.
