Definitions

  • the invention relates to a method for cooling hot bulk material according to the preamble of claim 1.
  • the bulk material For cooling of hot bulk material, such as cement clinker, the bulk material is placed on a cooling gas flow-through cooling grate. During transport from the beginning of the radiator to the radiator end, the bulk material is flowed through by cooling gas and thereby cooled.
  • the bulk material is transported by movable rows of cooling grates, which alternate with fixed cooling grate rows in the transport direction.
  • the hot bulk material is applied to a fixed ventilation bottom through which cooling gas can flow and transported by means of conveying elements which are movable to and fro above the aeration bottom.
  • the in the DE 878625 described conveying elements are formed by rods which are arranged above a fixed grate and extending in the longitudinal direction parallel to the grate level.
  • the rods are connected to a suitable movement mechanism, which allows a reciprocating movement in the transport direction of the bulk material.
  • suitable projections are provided on the rods to assist the conveying action.
  • conveying elements have been proposed with a substantially triangular cross-sectional shape, wherein the pointing in the direction of transport end face is formed substantially perpendicular to the transport direction and the rear end face forms an angle between 20 and 45 ° to the ventilation floor. While the forward vertical stroke the substantially vertical face achieves a good conveying effect, the conveying element can be withdrawn in the return stroke by its wedge shape under the bulk material, see, for example DE-4417422-A ,
  • the invention is therefore based on the object to improve the method according to the preamble of claim 1 with respect to the conveying effect.
  • the bulk material forms a relatively compact unit, which can be moved in the transport direction in the common forward stroke of the conveying elements.
  • the different groups of conveying elements are actuated individually and sequentially during the return stroke, due to the friction conditions in the good bed significantly less bulk is taken contrary to the transport direction, as in a common return stroke of all conveying elements.
  • Each group of conveying elements consists of at least one conveying element or conveying element strand.
  • the individual groups of conveying elements are provided alternately transversely to the transport direction of the bulk material.
  • the best results can be achieved.
  • the conveyor elements adjacent to the transport direction are arranged such that they are aligned to each phase of the movement sequence offset from each other in the transport direction.
  • the individual groups of conveying elements are arranged alternately in the transport direction of the bulk material.
  • cooler 1 for cooling hot bulk material 2 has substantially a fixed, can be flowed through by cooling gas ventilation floor 3 for receiving the bulk material and above the ventilation floor arranged, reciprocable conveying elements 4, 5, 6 for transporting the bulk material.
  • the bulk material 2 is formed for example by cement clinker, which is supplied from a rotary kiln 7 upstream of the cooler.
  • the bulk material passes through an oblique inlet region 8 on the fixed ventilation floor 3 and is transported there by means of the conveying elements 4, 5, 6 in the longitudinal direction through the radiator.
  • the ventilation floor is designed in a manner known per se and in particular has openings through which the cooling gas flows through the bulk material bed and thereby cools it.
  • the cooling air openings in the ventilation floor 3 are designed so that a sufficient amount of cooling air supplied, but rust diarrhea can be avoided.
  • the cooling air is expediently supplied below the ventilation floor 3.
  • the air ducts are not shown in detail for reasons of clarity.
  • the conveying elements are divided into at least two groups, wherein the at least two groups of conveying elements in the transport direction of the bulk material can be actuated separately from one another and counter to the transport direction.
  • the detailed design and the sequence of movement of the conveying elements in a first embodiment will be described below with reference to FIG Fig.2 and 3 explained in more detail.
  • three groups of conveying elements 4, 5, 6 are provided, which are alternately transversely to the transport direction of the bulk material (arrow 9 in FIG Fig.1 ) are arranged.
  • six conveying elements are provided across the width of the radiator 1, wherein the conveying elements 4.1 and 4.2 belong to the first group, the conveying elements 5.1 and 5.2 to the second group and the conveying elements 6.1 and 6.2 to the third group.
  • the conveying elements 4.1 and 4.2 belong to the first group
  • the conveying elements 5.1 and 5.2 to the second group
  • conveying elements 6.1 and 6.2 to the third group.
  • more or fewer conveying elements can be arranged over the width of the radiator.
  • Each conveying element 4.1 to 6.2 is connected via a carrier element 14.1 to 16.2 with suitable transport mechanisms 17.1 to 19.2.
  • 3 slots are provided in the ventilation floor through which the support elements 14.1 - 16.2 are passed.
  • the transport mechanisms which are associated with a specific group of conveying elements, can be coupled together for common adjustment of the conveying elements.
  • the reciprocating movement of the conveying elements is realized for example via a hydraulic drive.
  • 3a shows the state after the common forward stroke of all conveying elements 4.1 to 6.2. All conveying elements have been moved in the transport direction of the bulk material (arrow 9) by a length a. The bulk material lying on the ventilation floor and thus also on the conveyor elements is displaced in a corresponding manner.
  • conveying elements are arranged in the transport direction over the length of the radiator.
  • the conveying elements according to the first embodiment extend substantially in the longitudinal direction, ie in the transport direction of the bulk material (arrow 9).
  • the conveying elements differ from the first embodiment substantially in that they extend substantially transversely to the transport direction and are accordingly also supported via two carrier elements (for example 14.1) and connected to a transport mechanism (for example 17.1) or can be connected.
  • conveying elements according to the second embodiment in the basic position can be aligned transversely to the transport direction, as is the case in the first embodiment, in the second embodiment, adjacent conveying elements are arranged such that after each movement phase, i. after the common forward stroke and offset after each return stroke in the transport direction are aligned with each other.
  • the second embodiment can reduce the unwanted return transport of the bulk material during the return stroke of the conveying elements even better.
  • a third embodiment is shown, which differs from the preceding embodiments essentially in that only two groups of conveying elements are provided, which are also provided alternately in the transport direction 9 of the bulk material.
  • Each conveying element (for example 4.1) is connected via two carrier elements (14.1) to a transport mechanism (17.1). Conveniently, all conveyor elements of a group are moved via a common transport frame in the illustrated embodiment.
  • the stroke length of the conveyor elements should be designed to be adjustable.
  • the ventilation floor preferably extends horizontally, but also a downward slope would be conceivable.
  • the material of the conveyor elements must be selected according to the occurring temperature and the expected wear. For example, welding and casting constructions are possible. In the area of the bushings for the support elements also suitable seals must be provided in order to avoid rust diarrhea.
  • the embodiments described above are characterized in particular by the fact that the bulk material is not significantly carried along during the return stroke of the various groups of conveying elements. Accordingly, a smaller number of strokes is required for the movement of the bulk material, whereby in particular the wear of the conveying elements or the transport mechanism can be reduced.
