Definitions
- a cooling grate of this type in which a row of slides is arranged on the support plate, which carries the refrigerated goods, which is wedge-shaped and reciprocates along the surface of the support plate reciprocable are. Openings are provided below the slider in the support plate, through which a bolt is guided in each case. This is arranged with its upper end on the slide and with its lower end on a drive frame. The bolts are used to transmit the reciprocation of the drive frame to the slider.
- a similar cooling grate is known from US-A-2, 904,323.
- a disadvantage of these known cooling grates is that the slides have an inadequate conveying effect and the amount of cooling material falling through the openings is undesirably high.
- the invention has recognized that, thanks to the seal arranged on the collar, a better sealing of the openings against falling through of refrigerated goods can be achieved by a collar with a seal at the openings in the support plate, and at the same time a better conveying effect of the slide is achieved.
- the latter is achieved in that, due to the height of the collars, the slides are spaced from the support plate, that is, they protrude further into the bed formed by the goods to be refrigerated.
- the collars have the advantage that they protect the transformers from contact with the refrigerated goods. As a result, the transducers need at most only part of their length, which extends outside the collar towards the slide, to make their way through the refrigerated goods during their back and forth movement.
- a sealing packing cooperating with the transmitter is expediently provided on the collar. Although this is not absolutely necessary since the transformers move the refrigerated goods away from the edge of the collar during their forward stroke, so that the risk of undesired penetration of refrigerated goods is minimized in this phase, however, it can occur during the return stroke movement due to Chilled goods adhering to the transmitter such that a small amount of chilled goods would be introduced into the collar. This can be effectively prevented by a sealing packing on the collar.
- FIG. 1 shows a sectional view of a cooling grate according to the invention with a conveyor system according to a first exemplary embodiment of the invention
- cooling grate for is a cooler through which cooling gas flows from bottom to top and thereby serves to cool hot material, in particular cement clinker or other particulate bulk material.
- a sealing surface is formed by the upper edge of the collar 23 and the cladding 24, which cooperates with a counter-sealing surface which is formed by the cladding 61 of the cover plate 6, and thus a seal 7 forms.
- the cover plate 6 itself has an opening 62 in its center, the width of which is selected in accordance with the cross section of the thrust plate 4. At the edge of the opening 62 a holder 63 is arranged, by means of which the cover plate 6 is fastened to the thrust plate 4.
- the drive frame 3 is set into a lifting movement by means of the drive (not shown), the direction 9 of which is inclined by the elevation angle et with respect to the horizontal.
- the thrust plates 4, the slides 5 and the cover plates 6 thus also move along this direction.
- the slider 5 pushes with its shorter leg 52 part of the refrigerated goods 8 in front of them and thus causes the refrigerated goods 8 to move in the conveying direction 81.
- they give at least the area of the refrigerated goods displaced by the legs 52 during its forward stroke movement a vertical component of direction.
- this causes a certain mixing of the refrigerated goods 8 and, on the other hand, makes the refrigerated goods 8 displaced by the slide 5 easier to move, since the slightly displaced upward movement slightly lifts the refrigerated goods displaced from the underlying refrigerated goods 8 and thus counteracts the displacement Frictional forces are reduced.
- a third embodiment of the invention is shown. It corresponds essentially to the first and second exemplary embodiments. The same elements have the same reference numerals; a further explanation of their opening and their function is therefore not given below.
- the third embodiment differs from the first and second embodiments mainly in that the collar 23 and the spring plates 25 are made in one piece as a spring collar 27. This simplifies the manufacture of the arrangement, since a smaller number of parts is required. Since the spring plates are regularly subject to a certain amount of wear, it is expedient to replace the one-piece design on the support plate 2 by means of
