Definitions

  • the invention relates to sheet metal production, in particular to a device for descaling the surface of a flat steel.
  • a device for descaling the surface of a flat steel by means of grinding powder.
  • This device contains a working chamber with a sloping floor, which is filled from the side with abrasive powder, and with two powder compaction mechanisms arranged in opposite directions, the working elements of which are designed in the form of blades and face the vertical conveying plane of the flat steel.
  • This device is characterized as follows.
  • the powder not only fills the working space mentioned but also the entire space inside the working chamber.
  • the compaction mechanisms are completely immersed in the powder mass and when they are adjusted (for the approach of the working organs) a significant part of the energy of the drive is used to overcome the frictional forces between them and the powder. This reduces the efficiency of the drive and the Nutzkraftgrösse considerably, which ultimately leads to an increased energy consumption and unloading z underungs(7) because of insufficient Nu t z - force size reduced.
  • the lower powder compaction mechanisms work under conditions which differ from those of the upper mechanisms, since the powder reaches its work organs from above, from the space between the work organs of the upper compaction mechanisms and is partly already contaminated with scale. This also deteriorates the descaling and makes it on the flat steel length UNHAPPY p ich bugsssig.
  • the powder volume enclosed in the space between the working elements of the compaction mechanisms and involved in the descaling process is at most IO% of the total powder volume in the chamber, i.e. about 90% of the powder inside the working chamber does not take part in the descaling process. This makes it difficult to remove the scale from the powder and further reduces the descaling quality.
  • the grinding oily mass which is located between the non-working surface elements and the working chamber walls, proves to be less mobile and takes almost no part in the circulation of the powder.
  • the invention has for its object to develop such a device for descaling the surface of a flat steel, in which the constructive design of the means for feeding and removing the grinding powder from the chamber allows the circulation of the grinding powder inside the working chamber Design that this powder could be supplied independently to all work zones for flat steel descaling and could be removed independently from these zones so that all of the powder to be supplied could participate in the descaling process of the flat steel, which increases the descaling quality of the flat steel and reduces the energy expenditure in the operation of the device.
  • the device for descaling the surface of a flat steel which has a chamber for receiving an abrasive powder with at least two pairs. , for loading of the abrasive powder from the top into the chamber and in the lower part of this chamber therein superimposed powder compaction mechanisms, whose working members anen g of the flat steel plane of conveyance to form a space between the Häor and this plane facing means flaps arranged to unload the powder from the chamber ,
  • a system of channels for separate routing of the grinding powder from the means for filling the same into the space between the working means of the compression mechanisms and the flat steel conveying plane and a system of channels for separate removal of the powder from the space mentioned to the Has flaps for discharging the powder from the chamber According to the invention, a system of channels for separate routing of the grinding powder from the means for filling the same into the space between the working means of the compression mechanisms and the flat steel conveying plane and a system of channels for separate removal of the powder from the space mentioned to the Has flaps for discharging the powder from the
  • the working space allows the powder to get into to exclude the space between the non-working elements of the compaction mechanisms and the walls of the working chamber, which substantially (by 2.5 to 3 times) reduces the energy losses to overcome the friction between the compaction mechanisms and the powder, because the ratio of the area of the work organs (e.g. ß. blades) to the area of the remaining surface of the compaction mechanism usually I: 2.5-3.
  • This allows firstly to save energy, and secondly, to use the released energy part of the drive of the powder compacting mechanisms appropriately, i.e. for compressing the powder in the working space of the device, thereby increasing the surface descaling quality.
  • each compression mechanism also allows, unlike the prototype, a pure powder not only to feed the upper but also the lower compression mechanisms, ie the ent to improve the scaling quality of flat steel in the periods when the lower mechanisms work, thereby creating more uniform conditions for descaling over the length of the flat steel. This also increases the descaling quality of the surface of the flat steel.
  • the presence in the device of the system of channels for separate discharge of the powder from the working space of each compression mechanism to the flaps for discharging the powder from the chamber additionally improves the working conditions of the lower compression mechanisms and the descaling quality of the flat steel, since, in contrast to the prototype, the The bulk of the powder contaminated with scale does not get from the upper compaction mechanisms to the working elements of the lower mechanisms, but it reaches the flaps for unloading the powder separately via the channels mentioned.
  • the preferred embodiment of the device is that the channels for feeding the abrasive powder S having a rectangular profile in the space between the working elements of the lower compression mechanisms, and the flat steel conveying plane and consist of vertical and inclined portions, and the channels for the discharge of the powder from the Space between the same level and the working members of the upper compression mechanisms are designed in the form of a system of inclined parallel pipes which intersect the above-mentioned channels with a rectangular profile.
  • the channels with a rectangular profile for feeding the grinding powder into the working area of the lower compaction mechanisms make it possible to achieve the object of the invention in the simplest and most effective way: to connect the working area of the lower compaction mechanisms with the means for filling the powder and thereby the penetration to prevent the powder from entering the space between the non-working elements of the surface of the compaction mechanisms and the chamber walls.
  • This can be explained by the fact that the bottom of the channel with a rectangular profile is an obstacle to the penetration of the powder into the ineffective. Represents space behind the lower compression mechanisms, and the wall of this channel, which is opposite the floor, prevents the powder from penetrating into the ineffective space behind the upper compression mechanisms.
  • this channel from vertical and inclined sections ensures free movement of the powder inside the channel under the action of gravity, which would not be possible if horizontal sections were present.
  • the design of the ducts for the discharge of the powder from the working space of the upper compacting mechanism in the form of a system of inclined parallel pipes which intersect with the above-mentioned ducts with a rectangular profile allows the device to be made as compact as possible, since the inclined portion of the ducts is also compatible with the duct rectangular profile and the system of inclined pipes are housed in the same space between the upper and lower compression mechanisms.
  • the tubes are inclined on the opposite side with respect to the corresponding channels with a rectangular profile, and they are parallel to each other, so there is enough space in the zones of their intersection with the channel inside for the free movement of the pure powder see the pipes left.
  • the channels for the discharge of the powder from the space between the flat steel conveying plane and the working elements of the powder compacting mechanisms are insulated from one another along their entire length and are hermetically connected to at least one flap for discharging the powder from the chamber that is assigned to each channel .
  • Such a design of the above-mentioned channels and their connection to the powder discharge flaps are advantageous because in the device registered, the powder is discharged via each flap, which is only discharged from one working area of one of the compression mechanisms, therefore the powder is at the same pressure in each flap, and the pressure difference in the different channels does not prevent the powder from escaping from the channels in which the powder pressure is lower.
  • a better effect in solving the problem can be achieved if a flexible band of transport rubber fabric is between the working surface of the powder compacting mechanism and the channel directed towards this surface for the supply of the grinding powder into the space between the working member of the mechanism and the flat steel conveyor plane is assembled.
  • This makes it possible to completely separate the working space and the ineffective space of each compression mechanism inside the chamber, thereby not only preventing the ineffective space from being filled with powder, but also also exclude the penetration of powder particles into this space, which increases the operational reliability of the device with all the above-described perfections.
  • the strip must be flexible so that the movement of the compression mechanisms as they are removed from and approached by the flat steel during the descaling process is not prevented.
