Description
Technical Field
The utility model belongs to the technical field of sintering production, and particularly relates to a sintering material level flattening device.
Background
The sintering is a process of mixing and granulating various iron-containing raw materials, fluxes (quicklime, limestone, dolomite, magnesite and the like), fuels (coke powder, coal dust), return ores and the like, and then paving the mixture on a sintering machine trolley for ignition, air draft and sintering. The distribution state of the sintering mixture on the trolley is one of important factors influencing the quality of the sintering mineral products, when the mixture is distributed unevenly on the trolley, the uneven surface of the sintering material is easily caused, the uneven distribution of sintering wind is caused, the vertical sintering speeds of the whole surface of the material are different, and the quality of the sintering mineral products is deteriorated. And because the sintering machine has edge effect, namely the resistance of air inlet at two sides of the sintering machine trolley is smaller than that of the middle area, the vertical sintering speed of the edge sintering material is larger than that of the middle area, and large-particle sintering materials in the sintering material roll down to two sides of the sintering machine trolley easily during distribution, so that the original air permeability of the edge sintering material is better than that of the sintering material in the central area, the vertical sintering speed of the sintering material at the edge is accelerated, the excessively fast vertical sintering speed leads to incomplete reaction of the sintering material in the sintering process, the cooling speed is excessively fast, the crystallization is imperfect, the glass content of the edge sintering material is increased, and finally, the quality of sintered mineral products is influenced.

Detailed Description
The present utility model will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1-2, a sintering material level flattening device comprises a fixing rod 5 and a flattening plate 6, wherein the fixing rod is welded on a supporting beam 4 of a multi-roller distributor 3 and is positioned at the upper end of a trolley, and the distance between the fixing rod and the supporting beam is 100mm-200mm from the upper edge of the sintering trolley 4; a small ore tank 1 and a wide belt distributor 2 are arranged above the multi-roller distributor 3, a plurality of flat material plates 6 are arranged, the plurality of flat material plates are sleeved on a fixed rod, the total width of the flat material plates is equal to or smaller than the width of the trolley by 50-100mm, so that the flat material can be carried out on the whole sintering material surface, the thickness of two flat material plates close to the edge of the sintering trolley is larger than twice that of the middle flat material plates, and the reduction of the sintering material at the edge is larger than that of the sintering material in the middle area; the upper end of each flat material plate is provided with a connecting ring, the connecting rings are sleeved on the fixed rods and can rotate around the fixed rods and transversely move, and the flat material plates sink into the sintering trolley 7 under the action of dead weight and are in a hanging state.
The application method of the utility model is as follows: firstly, the flat material plates are connected with the connecting rings and then penetrate into the fixing rods during installation, and the positions of the flat material plates are adjusted to ensure that the flat material plates on two sides are slightly smaller than the width of the trolley, so that the trolley breast plates and the flat material plates are scraped and rubbed when no sintered material exists on the trolley. And secondly, fixedly connecting the fixing rod with the supporting beam of the multi-roller distributor. Then, start the sintering machine, will sinter the platform truck and be covered with the sintering material, flat flitch and sintering material face contact, adjust the position of flat flitch to both sides and be close to the platform truck breast board, under the effect of flat flitch, whole sintering material face is scraped to be flat, simultaneously under the pressure of flat flitch self weight, can carry out the appropriate swage to the sintering material on platform truck top layer to reduce the gas permeability of surface sintering material, simultaneously because the reduction of edge sintering material is greater than the reduction of middle part regional sintering material for the gas permeability of edge sintering material reduces, thereby can reduce the sintering machine edge effect.
