Description
Technical field
The utility model belongs to the technical field that steel enterprise sintering is produced, and relates to pallet Anti-air-leakage magnetic sealing means, is specifically related to the grid section briquetting pin hole sealing device that a kind of sintering machine uses, and solves the difficult problem of leaking out at pallet breast board pin-and-hole place.
Background technology
In iron ore powder sintering production process; vertical sintering speed and output and be approximated to proportional relation by the air quantity of the bed of material; if reduce the air leak rate of air curtain of pallet; then can significantly improve sintering output and quality; particularly ensure that the sintering quality at trolley breast plate position; and can thermal loss be reduced, reach the performance reducing energy consumption protection of the environment.For a long time, although agglomerant author takes many technological means in reduction sintering air leak rate of air curtain link, but air leak rate of air curtain still remains high, fundamentally do not solve a difficult problem of leaking out, especially the pin-and-hole at grid section briquetting place leaks out very serious, inleakage is suitable with the inleakage between chassis and slideway herein, its absolute air leak rate of air curtain accounts for 10%, the moisture content of raw materials for sintering cannot keep each position homogeneous constant on chassis, cause the edge effect of pallet both sides serious, have impact on the quality of sintering output and sintering deposit to a great extent.
The pin-and-hole at grid section briquetting place and briquetting are in the bottom high temperature position of pallet breast board, one is that pin-and-hole diameter becomes greatly very soon because chassis frequently overturns the wearing and tearing of discharging, and the bearing pin end diameter wearing and tearing on briquetting diminish, cause fit clearance herein to increase in a short time, increase inleakage further; Two is that under this position normality, environment temperature is more than 300 DEG C, and conventional nonmetallic materials are difficult to bear high temperature and frequently extruding and friction, and it is unreliable to seal, and is subject to space constraint and is difficult to install.When the bearing pin end of pin-and-hole and briquetting may wear to a certain degree, can only change trolley breast plate or again prepare grid section briquetting, result also in maintenance repair maintenance cost and increase, therefore this is each sintering producer large technical barrier anxious to be resolved.
Utility model content
The utility model is for a sealing difficult problem for current pallet grid section briquetting place pin-and-hole, it is simple that proposition one has structure, the pallet Anti-air-leakage magnetic sealing means of easy accessibility, employing comprises trolley breast plate, grid section, grid section briquetting, described grid section briquetting one end is square, be arranged on inside trolley breast plate, the other end is columniform bearing pin, be positioned at the magnetosheath bearing pin outside trolley breast plate being fixed with at least one permanent magnetism, the technical scheme of protecting cover is installed in one end that magnetosheath contacts with trolley breast plate, leak out for focus with what solve the grid section briquetting place pin-and-hole of pallet, novelty adopts magnetic sheath hermetically-sealed construction to solve the difficult problem in SINTERING PRODUCTION field.
The technical solution adopted in the utility model is:
Pallet Anti-air-leakage magnetic sealing means, comprise trolley breast plate, grid section, grid section briquetting, described grid section briquetting one end is square, be arranged on inside trolley breast plate, the other end is columniform bearing pin, it is characterized in that, be positioned at the magnetosheath bearing pin outside trolley breast plate being fixed with at least one permanent magnetism, the one end contacted with trolley breast plate at magnetosheath is provided with protecting cover.
In the outside of pallet grid section briquetting, the magnetosheath with permanent magnetism is installed, the iron dust containing in Iron Ore Powder is adsorbed in magnetic field around magnetosheath immediately, by the accumulation of iron dust containing in pin-and-hole gap, and the accumulation in magnetosheath and trolley breast plate gap, then iron dust containing just becomes packing seal, effective close packed is formed to these gaps, thus generation self sealing action, prevent leaking out of pallet grid section briquetting place's pin-and-hole, be extremely conducive to the energy-saving and cost-reducing of the quality of raising sintering deposit, output and SINTERING PRODUCTION.
Feature of the present utility model also has:
Described magnetosheath is fixed by nut, at its afterbody thread cutting in order to mounting nuts.
Described magnetosheath is fixed by split pin, exposes the radial bore of cylindrical end (bearing pin) afterbody of trolley breast plate side in order to construction opening pin at grid section briquetting.
The fixed form of magnetosheath on grid section briquetting can use split pin, also can use one or more nut.
Described magnetosheath self is with permanent magnetism, and its profile can be cylindrical, square or oval, also can with flange.
Described magnetosheath installs one.On the bearing pin of grid section briquetting, a magnetosheath can be installed, also multiple magnetosheath can be installed.
Also protecting cover is installed at the other end of magnetosheath.The position that magnetosheath contacts with trolley breast plate is provided with protecting cover, in order to protect magnetosheath, and also can install protecting cover at the other end of magnetosheath.
The beneficial effects of the utility model are:
Pallet Anti-air-leakage magnetic sealing means of the present utility model, outside pallet grid section briquetting, permanent magnetosheath is installed, iron dust containing in the magnetic field absorption Iron Ore Powder relying on magnetosheath to produce, on end face in the gap that iron dust containing accumulates in pin-and-hole and between magnetosheath and trolley breast plate, clog the gap existed between trolley breast plate and grid section briquetting, played and prevent from leaking wind action in sintering process.
Magnetic absorption iron dust containing is adopted to carry out self sealss and do not need other airtight and watertight padding, not by the impact in gap, pin-and-hole position, manufacture difficulty and expense low, and extend the service life of grid section briquetting and trolley breast plate, can effectively prevent leaking out of pallet grid section briquetting place's pin-and-hole, improve the utilization ratio of effective wind at chassis edge, restrained edge effect, improve productivity of sintering machine, drum strength and improve sintering deposit granularmetric composition, and reducing sintering deposit sinter return rate.
In a word, the utility model leaks out for focus with what solve the grid section briquetting place pin-and-hole of pallet, and novelty adopts magnetic sheath hermetically-sealed construction to solve the difficult problem in SINTERING PRODUCTION field.
