Abstract

The utility model belongs to the field of a sintering apparatus for metallurgy and iron-making. The sintering apparatus is in particular adaptable for a sealing device arranged between a stillage truck of a sintering device for iron ore powder and a sliding way arranged on the upper portion of a sinter wind-box. The formation of the apparatus is that fixed bolts connected with the stillage truck of the sintering device and locating pin shafts connected with a sealing slide-plate are all mounted on a frid. The utility model is characterized in that an integral spring is arranged between the frid and the sealing slide-plate, a spring locating seat is mounted on the sealing slide-plate, the inner surface of the frid is fixedly equipped with guiding rings, the number of the guiding rings is the same as the locating pin shafts which combines the integral spring of the frid and the sealing slide-plate which are then locked by a bolt chisel. Compared with the existing device, the utility model has the advantages of reasonable structure, low costs, convenient usage and maintenance and the like.

Description

Sintering pallet Monolithic spring seal arrangement

The utility model belongs to metallurgical iron making and sintering apparatus field, is specially adapted to the seal arrangement between iron ore powder sintering machine trolley and the sintering bellows top slideway.

At present, in the prior art, sintering pallet can directly influence output and the quality that sintering machine is produced sintering deposit with the quality of spring body sealability.Therefore, the sintering pallet sealing is subjected to paying close attention to widely, existing seal device of sintering machine pallet, and relatively more commonly used is the spring bearer plate Sealing Method, its spring element is generally helical spring steel wire or leaf spring.The two leaf spring Sealing Method of Chinese patent ZL00209144.5 sintering pallet.Adopt the Spring Steel Wire Sealing Method, be used for having between slide plate and the frid gap of a Fixed width, therefore, have the serious problem of leaking out, directly influence the sintering machine ordinary production.Adopt the leaf spring seal arrangement, prior art is that leaf spring is fixed between frid and the slide plate, like this with rivet, bring difficulty for running repairs and replacing component, make the necessary integral replacing of producer, cause cost of equipment to improve and waste, increased the cost of production of sintering deposit.

The purpose of this utility model is to propose a kind of project organization advantages of simple, and using effect is good, and installs installation and maintenance sintering pallet Monolithic spring seal arrangement easily.

According to the sintering pallet spring body that the utility model proposed, adopt the Monolithic spring body that the utility model proposed, can overcome the laying dust problem of leaking out in slit between drop bar and the frid, but also solve the problems such as I﹠M difficulty of this equipment.The composition of the utility model device can be described with reference to the accompanying drawings, and accompanying drawing 1 is the utility model device overall structure assembling schematic representation, and accompanying drawing 2 is accompanying drawing 1A-A cross-sectional view, and accompanying drawing 3 is the structural representation of the Monolithic spring in this device.Sequence number 1 is an alignment pin in the accompanying drawings, and 2 is frid, and 3 is guide ring, and 4 is Monolithic spring, and 5 is the spring positioning seat, and 6 is drop bar, and 7 is latch, and 8 is fixing bolt.Can find out with reference to the accompanying drawings, the utility model sintering pallet is the fixing bolt 8 that dress is connected with sintering pallet on frid 2 with the composition of spring body seal arrangement, with the alignment pin 1 that is connected with drop bar 6, it is characterized in that between frid 2 and the drop bar 6 Monolithic spring 4 being housed, on drop bar 6, be installed with spring positioning seat 5, at frid 2 inner faces guide ring 3 with alignment pin 1 equal number is housed fixedly, alignment pin 1 connects into integral body with frid 2 Monolithic springs 4 and drop bar 6, and is locked on the drop bar 6 by latch 7.Its feature of the utility model device fixedly is equipped with two or more spring positioning seats 5 in addition on drop bar 6.Can be found out that by accompanying drawing 3 the upper and lower end face that is shaped as of Monolithic spring 4 is a plane shape, the both sides end face is a waveform.

The utility model sintering machine is by fixing bolt 8 sintering pallet to be installed to sintering pallet bottom with the Monolithic spring seal arrangement with the working procedure of Monolithic spring seal arrangement, when the sintering machine proper functioning, being used for the action of gravity of chassis own makes the spring body pressurized produce elastic force, means of press seals slide plate 6 closely is pressed on the sealing chute on both sides, sintering machine wind box top drop bar 6 downwards.Because Monolithic spring 4 upper and lower surfaces of installing on drop bar 6 all are the planes, therefore, drop bar 6 is stressed even, contacts very closely with sealing chute, so sealing effect is fine.Because Monolithic spring 4 is that therefore, it is all more reasonable to install and change various component, can keep in repair easily, change the component of damage, thereby reduce production costs by the spring seat fixed position.

Compared with prior art, the spring element that the utility model adopted is a Monolithic spring, is respectively smooth rectangular surfaces with the upper and lower of Monolithic spring, and upper surface has 2 locating stud axis holes, lower surface has 2 or 2 with upper spring positioning seat hole, and the both sides of Monolithic spring 4 are wavy.Adopt this spring element, promptly can solve the leaf spring seal arrangement and change the component difficulty, can solve the problem of seriously leaking out of helical spring steel wire seal arrangement again.Therefore, the utility model is compared with existing equipment, have rational in infrastructure, cost is low and use, characteristics such as easy to maintenance.
