Abstract

The utility model relates to an elastic sealing ring cooler, in particular to the sealing between a trolley and a cooling cover of metallurgical ring cooler, which belongs to the technical field of ring coolers and is used for solving the defects of fast abrasion, fast effectiveness loss and short service life of the existing sealing plates. The construction comprises a trolley, a horizontal orbit, a sealing cover, an upper sealing plate and a lower sealing plate. The unique position is that the upper sealing plate and the lower sealing plate are omega shape, and the tail end is provided with an upper and a lower elastic plates; the tail of the upper and the lower elastic plates is fixed on the sealing cover and the horizontal orbit; the head part of the upper sealing plate and the lower sealing plate is contacted with the surface of the upper part and the lower part of the trolley, can form elastic and narrow line contact because of the elastic plates and the omega-shaped arc end head, can effectively eliminate leakage problem brought by abrasion gaps, enhances work efficiency of an air blower and the service life of the sealing plates, greatly reduces maintenance repair costs of the ring cooler, avoids frequent machine halt of the ring cooler, ensures normal run of sintering production, and is suitable for being used on the ring cooler.

Description

The elastic packing central cooler

Technical field

The utility model relates to the sealing between chassis and the cooling dome etc. in the metallurgical central cooler.Belong to the central cooler technical field.

Background technology

Central cooler is a widely used cooling infrastructure in metallurgy sintered, the pelletizing production, mainly form by motor, decelerator, drive unit, horizontal rail, chassis, slewing frame, blower system, seal closure etc., deadweight is generally about 500 tons to 1000 tons, add the sintering deposit that needs cooling, machine utilization is very big.Common heat-resistant rubber slab is all adopted in sealing between chassis and the seal closure at present, when chassis when circular orbit moves, rubber slab and chassis and seal closure produce sliding friction, under the operating mode of long-term heavy duty and continuous turning function, rubber slab very easily produces wearing and tearing, therefore the gap occurs between rubber slab and chassis and the seal closure, causes and leaks out, cause cooling effect to descend, the blower system power consumption rises; Wearing and tearing reduce the service life of rubber slab rapidly, and frequently changing sealing plate not only significantly increases the Maintenance and Repair cost, also makes the central cooler frequent shutdown simultaneously, has seriously disturbed the normal operation of SINTERING PRODUCTION.

Summary of the invention

The purpose of this utility model provides a kind of elastic packing central cooler, and the sealing device of this central cooler can be eliminated the sealing plate quick abrasion, defective fast, that service life is short lost efficacy.

The alleged problem of the utility model realizes with following technical scheme:

A kind of elastic packing central cooler, chassis, horizontal rail, seal closure and upper and lower sealing plate are arranged in the formation, its unique distinction is, described upper and lower sealing plate is that Ω type, tail end are connected with upper and lower elastic plate respectively, the tail end of last elastic plate is fixed on the seal closure, the tail end of following elastic plate is fixed on the horizontal rail, and the head of upper sealing panel contacts with the upper face of chassis, and the head of lower seal plate contacts with the lower surface of chassis.

Above-mentioned elastic packing central cooler, the described tail end of going up elastic plate is fixed on the seal closure by upper bracket, and the described tail end of elastic plate down is fixed on the bottom girder of horizontal rail by lower carriage.

Above-mentioned elastic packing central cooler, set up second lower seal plate and the reversing frame in the formation, the second lower seal plate also is connected with elastic plate second time for Ω type, tail end, reversing frame is fixed on the chassis, the tail end of second time elastic plate is fixed on the reversing frame, and the head of the second lower seal plate contacts with the upper angled surface of described lower carriage.

Sealing plate is the Ω type and has elastic plate in the utility model; can be on circular arc termination that makes Ω type sealing plate under the effect of elastic plate and chassis; lower surface forms rubber-like and contacts closely; and contact-making surface is very narrow line contact; it is big so effectively to have overcome the wearing and tearing that the rigid CONTACT WITH FRICTION of existing sealing plate large tracts of land caused; seal failure is fast; defectives such as service life is short; can realize the sealing between chassis and the seal closure etc. well; eliminate the problem of leaking out that bring in the wearing and tearing slit; improve the operating efficiency of blower fan and the service life of sealing plate; can therefore significantly reduce central cooler Maintenance and Repair cost; avoid the central cooler frequent shutdown, guarantee that SINTERING PRODUCTION normally moves.

Through measuring and calculating, behind employing the utility model, power of motor can reduce about 10%, and when power of motor was 1000KW, every central cooler can be saved about 800,000 yuan of the electricity charge every year, can obtain the good energy-conservation benefit.
