Description
Technical field
The utility model relates to metallurgical briquetting blowing-type central cooler, relates to a kind of inner lining structure of central cooler hopper specifically.
Technical background
Pelletizing central cooler hopper is installed in the chassis top, and the hopper of design is straight wall type at present, and antetheca is vertical wallboard with rear wall, and the both sides sidewall is near vertical (about 80 °) wallboard.Whole wallboard liner adopts corundum brick to build by laying bricks or stones, but has only designed one deck stainless steel brick plate in hopper wallboard bottom during design, upwards builds corundum brick continuously by laying bricks or stones on this layer brick plate, until the hopper top.When the rotary kiln discharge, red-hot pelletizing drops on the chassis through hopper, the temperature of this moment is about 1000-1100 ℃, the stainless steel brick plate of hopper bottom is directly impacted in strong heat radiation, because central cooler is continuous operation, so corrosion resistant plate large tracts of land oxidation soon, distortion are until scaling loss; After the brick plate scaling loss, the effect of its support top brick setting loses, and causes coming off of bottom brick setting; And brick setting is built by laying bricks or stones from bottom to top, so the bottom masonry comes off and causes the chain reaction of top masonry, finally makes hopper liner masonry large tracts of land come off the shutdown maintenance of having to.Because of the brick plate reason causes the come off situation of blowing out of masonry, just occurred in the shortest only 1-2 month, long also only 3-5 month of time, have a strong impact on the ordinary production of rotary kiln.
Summary of the invention
The purpose of this utility model provide at existing weak point in the above-mentioned prior art just a kind of structure more scientific and reasonable can effectively prevent the oxidation of corrosion resistant plate large tracts of land, distortion, until the inner lining structure of the central cooler hopper of scaling loss.
The purpose of utility model can realize by following technique measures:
The inner lining structure of the central cooler hopper of utility model comprises by the stainless steel brick plate of horizontal mode setting and the latticed wall liner pallet body that constitutes with the stainless steel separator of vertical mode setting, and is arranged on the high-strength corundum fireproof casting preformed block in each grid; Described high-strength corundum fireproof casting preformed block comprises draw-in groove type prefabricated section and card bench-type prefabricated section; The concave shaped draw-in groove that described draw-in groove type prefabricated section processes by its side lower part is inlay on bottom stainless steel brick plate, and the Ka Tai that card bench-type prefabricated section processes by its bottom surface builds by laying bricks or stones on the stainless steel brick plate of upper strata.
The width of the stainless steel separator described in the utility model be the stainless steel brick plate width 2/3, the width of stainless steel brick plate is 2/3 of a castable refractory prefabricated section width; The groove depth of the concave shaped draw-in groove that processes on the described draw-in groove type prefabricated section and groove width are greater than stainless steel brick plate width, thickness; Be positioned at the table top of low table for matching with the stainless steel brick plate of the Ka Tai on the card bench-type prefabricated section bottom surface, the width of this low table is greater than the width of stainless steel brick plate, and the vertical height between the paramount table top of low table is greater than stainless steel brick plate thickness.
The setting of draw-in groove type prefabricated section can make bottom brick plate (ground floor brick plate) be subjected to effective protection of this prefabricated section in the utility model; avoided thermal-radiating direct impact; alleviated its suffered temperatures involved; reduce its oxidated degree, thereby avoided brick plate to be taken place by the situation of scaling loss at short notice.The setting of upper strata (second and third layer) brick plate is in order to prevent that whole liner masonry collapses after bottom brick plate (ground floor brick plate) is by unexpected scaling loss, and the setting of card bench-type prefabricated section can play protection upper strata (second and third layer) brick plate be subjected to strong heat radiation directly impact and oxidized, produce distortion, until the generation of burning damage accident; Simultaneously for the consideration that improves the brick plate structural strength, between each layer brick plate, stainless steel separator is set, form latticed brick hold structure, to play the solid effect of drawing, avoid because the distortion of local brick plate causes masonry whole loosening situation in bottom to take place, be able to effective prolongation in service life of whole hopper liner thereby make.
