Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for abrading hot materials.

Recently, as an energy saving measure, there has been a demand for cleaning high temperature billets, etc. that have just come out of the furnace. However, when attempting to clean such high-temperature materials using conventional polishing equipment, various problems arise because no special consideration is given to heat. In other words, since the radiant heat of an object is proportional to the fourth power of the absolute temperature, the radiant heat of a material with a temperature of about 1000°C is significant, and unless some measure is taken, it will cause the cabinet to deform, and if the cabinet deforms, the parts installed there will be damaged. The projection direction of the projector will change, making it impossible to shoot uniformly, making it impossible to control the quality of the material to be polished, and causing adverse effects such as seizure on the projector, motor, etc., resulting in short-term damage. This can cause problems such as when the device becomes unusable.

This idea was created in view of these points.
By bringing the cooling fluid into contact with the cabinet for direct cooling, and by ventilating the air inside the cabinet to prevent the occurrence of convection, the cooling effect is synergistically enhanced, thereby stabilizing the grinding work of high-temperature materials. This is what makes it possible.

Embodiments of the present invention will be described below based on the drawings.

1 and 2 show an example of the present invention, in which a plurality of projectors 4 are provided in a cabinet 3 capable of passing high-temperature material 1 through an opening 2, and a high-temperature material 1 introduced through the opening 2 is provided. Material 1, projector 4
The abrasive material 5 is projected to perform the cleaning.

A cooling fluid injection nozzle 7 for spraying a cooling fluid 6 such as cold air or water is disposed around the outer periphery of the cabinet 3. At this time, the nozzle 7
It is advisable to arrange the projector 4 and its mechanical parts, such as its motor, so that they can be locally strongly cooled. In the figure, numerals 8 and 9 are nozzles provided at the entrance and exit sides of the cabinet 3 for the high-temperature material 1. Further, the temperature of the air inside the cabinet 3 increases due to the convection effect caused by the high temperature material 1. Therefore, in order to collect the shots that have fallen to the lower part of the cabinet 3 due to the cleaning, a shot collection device 11 equipped with a vacuum pump 10 is used to simultaneously ventilate the air inside the cabinet 3. At this time, the air intake port 12 for ventilation
is preferably provided above the cabinet 3.

According to the above configuration, by directly cooling the outer periphery of the cabinet 3 with the cooling fluid injection nozzle 7, problems such as deformation of the cabinet 3 due to heat and seizure of the projector 4 and its motor etc. can be solved. Furthermore, since the inside of the cabinet 3 is ventilated by taking in cold air through the air intake port 12 by the suction of the vacuum pump 10, convection of air inside the cabinet 3 is prevented.
In addition to direct cooling of the cabinet 3, the cooling effect can be synergistically enhanced.

FIG. 3 shows another embodiment of the present invention, in which the cabinet 3 is of a jacket type, and cold air or water is injected into the space 13 through an inlet 14 in order to directly cool the cabinet 3. Cooling is performed by introducing the cooling fluid 6 and leading it out from the outlet 15. Further, at this time, the mechanical parts are similarly configured in a jacket type so that they can be cooled at the same time. Also the third
In the case shown in the figure, the shot is collected by the screw conveyor 16, so as a measure to prevent convection in such a case, a dust collection duct 17 is provided at the top to perform suction. . Then, the cold air flowing in through the gap between the openings 2 and the like flows inside the cabinet 3 toward the dust collecting duct 17, thereby preventing air convection from occurring inside the cabinet 3.

Note that the present invention is not limited to the above-mentioned embodiments, and various changes may be made without departing from the gist of the present invention.

According to the high-temperature material polishing apparatus of the present invention described above, the following excellent effects can be achieved.

(i) Direct cooling by bringing the cooling fluid into contact with the cabinet and prevention of convection by ventilation can synergistically enhance the cooling effect and suppress the temperature rise of the entire polishing device.

(ii) Deformation of the cabinet due to heat can be prevented, and the direction in which the abrasive material is projected by the projector is stabilized, so that consistent shots can be performed and good quality control can be achieved.

(iii) Eliminates negative effects on the projector and its motor, resulting in stable cleaning work and extended service life.
