Described longitudinal sealing device is for dividing body structure, and a part is a L type baffle plate, and another part is that two L type baffle plates connections form the suitable formation active card of two parts buckle structure.
Be provided with scraping wings between the adjacent leakage-proof grid plate on each grate plate brace summer.
Grate plate unit on the moveable longitudinal beam adjacent with lower house is provided with the longitudinal sealing device, and the part of longitudinal sealing device is connected on the lower house, and another part is connected on the grate plate unit.
Each moveable longitudinal beam bottom is provided with guider and transmission device.
Two guide plates that described guider is provided with by the moveable longitudinal beam bottom and two suitable directive wheels on the lower house are formed.
Also be provided with several gripper shoes in each moveable longitudinal beam bottom, the tugboat on each gripper shoe and the lower house is suitable, forms transmission device.
Each moveable longitudinal beam and several grate plate unit on it, and longitudinal sealing device, guider and transmission device are formed a cooling, pusher, motion module.
The utility model has the advantages that: 1, the scraping wings at the longitudinal sealing device of leakage-proof grid plate both sides, two ends forms a quadra, makes to cover one deck cold burden on the grate plate all the time, the material of red heat and grate plate is separated, thereby the heat-resisting requirement of grate plate is reduced.Adopt originally general steel sheet by cut, roll over, processing technology manufacturing such as weldering, alleviated the weight of grate plate greatly, save a large amount of expensive heat-resisting steel material and machined expenses, reduced the manufacturing cost of grate plate significantly.
2, because the longitudinal sealing technology between employing leakage-proof grid plate and motion module, the bed of combing does not have the material of leakage, therefore ash bucket, electricity arc valve and grog machine for zipper that traditional cooling machine is positioned at the lower house bottom have been cancelled, reduced the manufacturing cost of cooler, can reduce about cooler height 3000mm simultaneously, bring the reduction of cement producing line all devices height such as rotary kiln, preheater, reduced the construction costs of cement producing line significantly.
3, modularized design:, can utilize module combinations to become any specification cooler as required cooling, pusher, the motion module of leakage-proof grid plate, grate plate brace summer, longitudinal sealing device, scraping wings, moveable longitudinal beam and transmission device composition cooler.
4, replace the horizontal pusher motion mode of traditional cooler (movable comb board roof beam and on activity grate plate pusher) with the lengthwise movement of cooling, pusher, motion module, can need to realize that all modules of forming cooler are moved simultaneously, part of module is moved and the multiple pusher mode of individual module motion according to (cooling effect, thickness of feed layer etc.), improve cooling effectiveness and cooling effect, reduce the power consumption of cooler, energy-efficient.
5, cancel the power transmission shaft and the movable frame of traditional cooler, reduced manufacturing cost and fault rate, improved the running rate of cooler simultaneously.
