DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to sludge, dust, excavated slag, scale, and the like, which are deposited inside and outside equipment such as steel mills, non-ferrous mills, mines and other smelters, and power plants. In addition, in the production and manufacturing processes in the agricultural and mining industry, including sediment such as livestock manure and straw used for the protection of livestock deposited in stables such as poultry farms and pig farms or stables such as cattle and horses, The present invention relates to a device that crushes generated sediment or snow compacted or frozen in a cold region (in the present specification, these are referred to as “sediment”) and sucks and conveys it. The term “crushing” as used herein refers to a part or the whole of a series of operations for excavating, excavating, digging and crushing a scale or the like.

[0002]

2. Description of the Related Art Taking a steel mill as an example, deposits are deposited in a sinter ore manufacturing facility and its transporting apparatus, a heating furnace and a soaking furnace, and the like. These deposits
It tends to reduce the intended performance of the device. Taking a heating furnace or a soaking furnace as an example, a scale layer deposited on the hearth worsens the combustion situation in the furnace, which causes uneven heating of the slab, resulting in dimensional accuracy and shape defects after rolling. Become like Therefore, it was necessary to periodically remove the scale layer deposited in the furnace.

[0003] Conventionally, the scale layer deposited on the hearth has been removed.
After cooling the furnace down to about 50 ° C,
Dozens of workers per furnace entered the furnace, excavated the scale layer using a pickaxe or rock drill, etc., and manually discharged the excavated scale outside the furnace. Since the latent heat inside the scale is released by excavation of the scale layer, it is inevitable that the temperature inside the furnace will rise again. Therefore, the work in the furnace is limited to a few dozen minutes at a time, requiring constant replacement. As a result, the furnace shut down time was prolonged, a large amount of labor had to be secured, and work efficiency was poor.

[0004] There have also been proposed devices for performing the work of crushing the sediment by human power and devices for sucking and discharging the crushed scale. In other words, Japanese Patent Application Laid-Open No. 7-146084 discloses that a crushing drum includes a moving vehicle that moves on a scale layer and a crushing drum that is rotatably supported by the moving vehicle. A device for crushing and peeling a scale layer by moving a crushing claw projecting from a drum into a scale layer while scooping it up has been proposed. Japanese Patent Application Laid-Open No. 6-240324 discloses a moving vehicle moving in a furnace. An apparatus has been proposed in which a suction port of a suction hose connected to a vacuum suction device outside the furnace is attached to the furnace, and the crushed scale is suctioned and carried out of the furnace.

[0005]

In the apparatus disclosed in Japanese Patent Application Laid-Open No. 7-146084, which crushes sediment, only the crushing of the sediment can be performed, and the transport of the crushed sediment must be performed manually. . Even in the apparatus of JP-A-6-240324 for carrying out the crushed sediment, the crushing of the sediment must be performed manually, and if the crushing and unloading are to be performed without relying on the human, the crushing apparatus and the unloading apparatus are required. Two devices are required. In addition, in the case of a conventional apparatus for sucking deposits, only the suction port and the deposits around the suction port are sucked, and a wide area cannot be sucked.

A first object of the present invention is to crush and carry out a sediment with one apparatus, and to suck and carry out all the crushed sediment while crushing, thereby improving work efficiency. A second object is to provide a moving vehicle that moves on a sediment, and a crushing drum that is attached to the moving vehicle so as to be rotatable in both forward and reverse directions and has crushing claws. In a device for crushing sediment by moving the crushing claw into the sediment by rotating the crushing drum with a motor on the sediment, suctioning and discharging the crushed sediment can be performed. It is intended to provide a device that can do this.

[0007]

An apparatus for achieving the first object is a mobile vehicle capable of moving on a sediment by remote control or microcomputer control, or being towed by a towing device, or being self-propelled, and a hood attached to the mobile vehicle. A spiral wing that is rotatably supported in the horizontal direction in the inside, a crushing claw of sediment provided on the spiral wing, a driving device that rotationally drives the spiral wing, and a vacuum suction device that is connected to and held by the moving vehicle , Consisting of a suction hose provided on at least one side of the front and back of the spiral wing, and by rotating the spiral wing, the excavated sediment is helically fed while excavating with the crushing claw and collected at the suction port. According to the present apparatus, the sediment crushed by the spiral wing is collected at the suction port, so that the sediment crushed by the spiral wing can be carried out in a wide range.

The spiral wing of the above-described device is supported by the suction port of the suction hose, and can be switched between a crushing position in which the suction blade moves up and down together with the suction port and comes into contact with the sediment, and a retracted position where the wing is lifted from the sediment and separated. It is desirable to make.

[0009]

1 and 2 show an apparatus for crushing and suction-conveying a scale layer in a furnace, which is self-propelled and operated by a driver or remotely controlled from outside the furnace. The crawler type moving vehicle 1 has a duct 2 having a tip bent downward and one end having a suction port, which is attached so as to be able to ascend, and an air cylinder 3 which elevates the duct 2 to make the suction port a scale layer. It can be switched between a use position where it touches the ground and a non-use position where it is retracted above.

The duct 2 is connected to a vacuum suction device (not shown) provided outside the furnace by a suction hose 4, and a hood 5 is attached to a suction port. Then, the duct 2 is driven to rotate by an air motor 7 attached to the duct 2. The spiral blade 6 includes a spiral blade for a right-hand screw and a spiral blade for a left-hand screw on both sides of the suction port. Each spiral blade holds a hook-shaped crushing claw 8 in a spiral direction as shown in FIG. While protruding at intervals,
It has a structure in which a pair of tongue-shaped crushing claws 9 that warp laterally in opposite directions are attached between the crushing claws.

According to the present apparatus, the duct 2 is moved downward by the air cylinder 3, the suction port is grounded to the scale layer 11, and the vehicle 1 is switched to the use position, and the moving vehicle 1 is spirally moved on the scale layer. When the wing 6 is driven to rotate by the air motor 7, the crushing claws 8 and 9 dig into the scale layer 11 to crush the excavated scale layer. The crushed scale is transferred to the center having the suction port with the rotation of the spiral blade 6, and is suctioned and discharged from the suction port. When the crushing is completed, or when the crushing is interrupted and moved, the duct 2 is lifted by the air cylinder 3 and the suction port is retracted to the non-use position.

[0012]

The present invention is configured as described above and has the following effects. According to the device of claim 1, crushing of sediment and carrying out of crushed sediment are performed by one device, labor saving of crushing and carrying out becomes possible, and separate devices are used for crushing and carrying out. It is not necessary to use it, and since it is carried out while crushing, only one device is required, work efficiency is improved, and sediment crushed by the spiral wing is collected at the suction port, so the crushed large It is possible to carry out the sediment in the area, and the work efficiency is further improved.

According to the crushing claw according to the second aspect, the scale dug up by the first crushing claw is cut off by the second crushing claw and finely crushed. According to the apparatus of claim 3 , when the spiral wing is not used with the suction port,
Since it can be evacuated upward, there is no hindrance during traveling.
