Definitions
- the invention relates to a method for entering bulk material on a belt of a rotary hearth furnace, which has hoods that form a ring covering the belt, and a corresponding device for this.
- Conveying device for loading and unloading the heating material in the area of the door opening in which a large number of gripping devices are provided which can feed the material to be heated from the conveyor device through the furnace openings to the contents of the furnace arranged in the furnace or remove them.
- the oven known from this is a so-called push-through oven, in which the goods are not transported on a circular path.
- EP 0 058 736 B1 is a rotary hearth furnace with a heating device for generating a hot zone, with a device forming an insertion station, via which parts can be inserted into the furnace.
- the invention has set itself the goal of a method and a corresponding
- the introduction device is constructed in such a way that the material feed is broken down into different stages.
- the individual stages can be easily monitored and the individual stage transition can be safely controlled.
- the material is fed in with a constant amount.
- a movable conveyor belt is used, the discharge quantity of which is monitored and whose discharge position is adjustable.
- the position of the transfer point is controlled so that on a further conveyor (level 2) a material layer is set, the height of which depends on the structural conditions of the rotary hearth furnace and here the size of the belt. It is taken into account here that the individual belt positions have different conveying speeds depending on their distance from the center of the rotary hearth.
- Layer height on this conveyor is highest on the outside of the furnace belt, which is furthest from the center of the furnace. Overall, the layer height has a cross-sectional area that represents a square that tapers conically towards the center of the furnace.
- the exact surface shape is set by a smoothing device.
- This conveyor is operated at a predeterminable speed.
- the smoothing device and the constant speed make it possible to set a delivery rate that is fixed directly from its position of the cross-sectional area at the discharge relative to the distance to the center of the furnace.
- the material from the above-mentioned funding is gently thrown onto the stove band at the discharge point.
- the relative speed of the hearth belt to the speed of the conveying means now determines the layer height, specifically over the full width of the furnace belt.
- the layer height can be set particularly low and with a high degree of certainty by the exclusive dependence of the speeds of the furnace belt and the conveyor belt.
- layer heights of only 30 mm are required on the conveyor belt with an oven belt width of up to 7 m. These high accuracies are achieved by the device according to the invention, layer heights of 200 to 400 mm being provided on the conveyor belt.
- the device according to the invention is particularly suitable for coarse-grained bulk materials.
- a swiveling belt can also be used as the first material feed.
- An endless belt is advantageously used as the conveyor unit. This can have an edge-shaped elevation directly at its edges or a side bar is provided regardless of the conveyor belt. With this lateral limitation, the bulk material on the conveyor belt can be set exactly at the desired height.
- the bulk material can also be conveyed gently through a vibrating trough that has a fixed strip on the side.
- the oscillation frequency is set so that the conical cross-sectional area is maintained.
- Figure 1 An overall view of the rotary hearth furnace.
- Figure 2 The diagram of the input device.
- FIG. 1 shows a rotary hearth furnace 11 with a center point M, the material conveyor belt 13 of which is covered by hoods 14.
- a hood cutout 12 is provided for the input device.
- FIG. 2 shows a section of the range 13 which is moved at the speed vp.
- the hearth belt 13 is covered with bulk material in the height hrj.
- An endless belt 21 is arranged above the hearth belt 13 and is covered with material which has a height of hjp on the side facing the center of the rotary hearth furnace, h m F in the middle and height h a p in the outer region.
- the endless belt 21 is moved at the speed vp.
- the surface of the material is carried out under a smoothing roller 31.
- Limits in the form of limiting strips 24 are provided below the underside of the smoothing roller 31 in the edge regions of the endless belt 21.
- Wings 32 are arranged on the smoothing roller 31 - distributed over their axial length - and ensure that the material is distributed on the endless belt 21.
- a conveyor belt 41 is provided which has a drive 42. As indicated by the arrows, the conveyor belt can be moved back and forth. In addition, the conveyor belt 41 can be pivoted about an axis lying outside the rotary hearth furnace. This is also shown in the figure by a double arrow. This pivoting serves to improve the material feed to the endless belt, in particular to achieve the different dumping heights.
