Description

Mobile Foreign Object Collection Device {A MOVABLE FOREIGN SUBSTANCE PICKUP DEVICE}

The present invention relates to a foreign matter collection device, and more particularly to a mobile removal device that can more effectively remove the foreign matter accumulated in the ash or coal ash generated in the boiler.

In general, in a boiler system that burns coal or burns coal and petroleum, coal ash such as fly ash and bottom ash is emitted as industrial waste after combustion.

On the other hand, the amount of waste discharged varies depending on the type of coal, but is discharged to about 10 to 30% of the weight of the continuous coal is disposed of.

On the other hand, conventionally, since no separate device has been developed for the collection of such waste, the worker has performed work by hand using a work tool such as a shovel.

However, due to the simple repetitive work when performing the above work, there was a problem in that the work efficiency is reduced due to the input of a large amount of manpower when the work occurs.

The present invention has been proposed to improve the problems in the prior art as described above, by providing a mobile device for easily moving the collection work to collect the foreign matter such as coal ash accumulated in a certain amount on the work site, It aims to improve work efficiency while reducing costs.

The present invention for achieving the above object, the spline shaft is connected to the motor shaft of the drive motor; A handle shaft which is fastened to the spline shaft and protrudes symmetrically shaped handles on both sides; A drive shaft connected to the handle shaft by a coupling; A screw configured at one end of the drive shaft; A guide tube for guiding foreign substances introduced from the outside by the rotational driving of the screw; A support bearing for supporting the rotation of the screw in the guide tube; The spline shaft and the handle shaft, the drive unit housing is configured to be connected to the guide tube in order to prevent the external exposure of the drive shaft;

The foreign matter collection device of the present invention, the movement is easy to move quickly to the work site where the foreign matter is accumulated, and the effective foreign material collection and removal can be made by the screw-type transfer pump principle.

In particular, by adopting the spline shaft on the drive shaft to enable stroke adjustment can maximize the work efficiency.

Figure 5 is a state diagram when the screw down of the present invention foreign matter collection device.
Figure 6 is an enlarged view of the tip portion of the guide tube according to another embodiment of the present invention.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, looking at the structure of the collection device according to an embodiment of the present invention, the spline shaft 20 is connected to the motor shaft of the drive motor 10, the handle shaft 30 is coupled to the spline shaft 20, The handle 31 is rotatably configured by the ball bearing 32 on the handle shaft 30 in a symmetrical form on both sides.

In particular, at one end of the spline shaft 20, a plurality of guide grooves 21 are formed in the longitudinal direction on the outer circumferential surface, and guide protrusions 33 are formed on the inner circumferential surface of the handle shaft 30 corresponding thereto, While the rotational force of the shaft 20 is smoothly transmitted to the handle shaft 30, the handle shaft 30 has a structure capable of adjusting the raising and lowering height according to the sliding flow in the longitudinal direction of the spline shaft 20.

And, the handle shaft 30 is connected by the drive shaft 40 and the coupling 45, the lower end of the drive shaft 40 is configured with a screw 50 for forced transfer of foreign matter.

On the other hand, the guide tube 60 for guiding the foreign material conveyed by the screw 50 is configured in a form surrounding the drive shaft 40, the guide tube 60 is formed at the lower end and the inlet is formed on the top The outlet portion forms a flange portion 63 for coupling with a separate collection container, and the upper portion of the guide tube 60 is integrally connected to the drive unit housing 80 in which the drive parts are built.

In addition, a support bearing 70 for supporting the drive shaft 40 is mounted in the guide tube 60, and a guide hole 81 for guiding the lifting and lowering of the handle 31 is provided in the drive part housing 80. It is formed in the shape of "H".

In the figure, reference numeral 11 denotes a speed reducer.

The working effect of the use of the present invention removable foreign matter removal device constituting such a structure will be described.

First, after the removal device of the present invention is moved to a work site where coal ash and the like are accumulated, a separate collection container is connected to the discharge side flange portion 63 of the guide tube 60 or a collection box such as a bag or the like. Will be connected.

Thereafter, the foreign materials accumulated by driving the power in a state in which the lower portion of the inlet portion of the guide tube 60 is placed in the stacked state are transported and collected through the guide tube 60.

That is, by applying power to the drive motor 10, the drive shaft 40 received the rotational force through the spline shaft 20 and the handle shaft 30 is rotated together with the screw 50, such a When the operator lowers the handle 31 while the power is being driven, the handle shaft 30 pushes the driving shaft 40, so that the screw 50 descends as shown in FIG. 5. It will protrude.

Therefore, it can be seen that the foreign matter is transported through the guide tube 60 and collected by the collecting box 61 by driving the protruding screw 50, so that foreign matters such as coal ash can be more efficiently transported and collected.

On the other hand, Figure 6 shows an enlarged cross-sectional view of the inlet side of the lower end of the guide tube 60 according to another embodiment of the present invention, as shown in the permanent magnet 62 is mounted to the inlet.

In particular, the inlet portion of the guide tube 60 to which the permanent magnet 62 is attached is made to form a fallopian tube to form a shape in which the diameter (D) gradually increases toward the end to facilitate the selection of metals more easily. Do.

As the permanent magnet 62 is mounted as described above, the metallic foreign matter contained in the coal ash during the collection process is selected by the strong magnetic force of the permanent magnet 62 so that the metal material is introduced into the guide tube 60. (50) Breakage can be prevented.

In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the structure of the foreign material collecting device of the present invention may be variously modified and implemented by those skilled in the art.

It should be understood, however, that such modified embodiments are not to be understood individually from the spirit and scope of the invention, and such modified embodiments are intended to be included within the scope of the appended claims.
