The utility model discloses a paddle-type thrust device for delivering high-temperature materials, which is characterized in that high-temperature clinker calcined in a rotary cement kiln is dumped on a grate cooler for delivery and cooling; each grate bed for delivering the high-temperature clinker is modified into a ladder-shaped structure; a grate element is placed on each ladder surface; a paddle-type thrust unit is mounted between every two adjacent ladders; and a driving unit is adopted to realize reciprocating swing of the thrust units and push the high-temperature clinker on the grate element of the ladder surface to move to next ladder surface so as to realize delivery of the entire clinker layer. According to the addle-type thrust device for delivering high-temperature materials, the material feedback problem during the clinker delivery process is effectively solved, the entire clinker layer is fully stirred and homogenized on the grate beds, heat exchange efficiency and delivery rate are improved, the thrust units are convenient to mount and dismount, the number of the thrust units can be adjusted according to the grate bed structure, and flexibility of grate bed adjustments is increased.

Description

A kind of oar formula thrust unit for delivery of high-temperature material

Technical field

The utility model relates to a kind of oar formula thrust unit for delivery of high-temperature material, is particularly useful for carrying high-temperature cement accumulation grog on the cold prevention machine grate bed.

Technical background

Cold prevention machine is the critical host equipment in the grog firing system of cement plant, and its major function is that clinker is cooled off, carries, and simultaneously for rotary kiln and dore furnace etc. provides hot-air, is the capital equipment of firing system recuperation of heat.Whether quick should take all factors into consideration for the mode of movement of grog on the grate bed, whether exist and leak material, feed back, to the equipment attrition situation and situation such as whether be convenient to cool off in order to reach desirable operating mode.

The cold prevention machine employing of the 4th generation is the reciprocal way of propelling of grate bed horizontal bar fixedly, exist the problem of feed back at the grog throughput direction, the full-movable push bar cold prevention machine of the ten thousand big dragons (patent No.: CN200710133642.9) the movable expeller of triangle is installed in the ebb place of setback wire grate plate, simple in structure, be convenient to maintenance, life-span is long, but also has the feed back problem; People's such as Chen Zeyu the new and effective reciprocal promotion grate type cooler (patent No.: CN03237969.2) designed novel electronic arc air valve, prevented effectively the fine grained grog fill the air fall into the inflation beam in, the fountain of having got rid of the fine grained grog flies upward, the relative complex but the grate bed structure becomes; Wen Yan for delivery of with the conveying device of the cooling down high-temperature bulk material (patent No.: CN200710139365.2) do the reciprocating pushing block that is snakelike distribution in the left and right sides by one group of Driven by Hydraulic Cylinder and promote to roll about grog, each pushing block stirs and promotes forward grog as turnplow simultaneously, make grog better and refrigerating gas carry out heat exchange, improved the heat exchanger effectiveness of cooler, but driving velocity is not good; (application number: CN102767966A) mode of movement that adopts semicircle to put pushing block has solved the problem of feed back to a certain extent for the conveying of people's such as Wen Yan, Jing Tong semicircle pendulum block-pushing high temperature chamotte and cooling device, but there is the dead angle in semicircle piece rear, and the part grog is difficult for promoting; A kind of cold prevention machine of people such as Wang Lijun (patent No.: CN202350544U) can realize the combination of grate bed unit, back and forth promote but the way of propelling still is based on horizontal bar, not make improvements.

The utility model content

Can't overcome and carry back material in the grog course of conveying and improve heat exchanger effectiveness and problems such as transfer rate in order to overcome prior art, the utility model provides a kind of oar formula thrust unit for delivery of high-temperature material.

The technical scheme that the utility model adopts is: will be poured over through the burnt high temperature chamotte of cement rotary kiln and carry on the cold prevention machine and cool off, and transform as stepped for delivery of the grate bed of high temperature chamotte, lay grate unit on each cascaded surface, between every adjacent two ladders oar formula pushing unit is installed then, realize the reciprocally swinging of pushing unit by drive unit, the high temperature chamotte that promotes in the cascaded surface grate unit moves to next cascaded surface, thereby realizes the conveying of whole grog layer.

Compared with prior art, the beneficial effects of the utility model are: efficiently solve the feed back problem in the grog course of conveying; Whole grog layer is fully stirred on the grate bed, and the homogenizing bed of material improves heat exchanger effectiveness and transfer rate; Pushing unit is convenient to dismounting, can adjust the number of pushing unit according to the grate bed structure, has increased the flexibility that the grate bed is regulated.

The specific embodiment

Fig. 1 is the disclosed embodiment of the utility model, demonstration be that its structure chart as shown in Figure 2 for delivery of the schematic diagram of the oar formula thrust unit of high-temperature material.Clinker is poured into material bed 1 by the revolution kilneye after the calcining of rotary kiln.Drive unit (motor) drives sector gear V 19 by crank and rocker mechanism and rotates, driving axle III 17 rotates, oar formula pushing block 3 on the axle III 17, sector gear IV 18 are rotated at this moment, sector gear IV 18 and 16 engagements of sector gear III, driving axle II 14 rotates, in like manner realize oar

formula pushing block

3,15 rotations of sector gear II on the axle II 14, according to type of belt drive like this, the rotation of sector gear I 10 has also realized the motion of oar formula pushing block 3 on the axle I 5.The oar formula pushing block 3 that can realize each ladder place by the above-mentioned way of propelling rotates to a direction simultaneously.During duty, grog is swum over to the downstream from the grate bed and is piled up, when the oar formula pushing block 3 on the axle I 5 (from grate bed top) when rotating an angle clockwise, oar formula pushing block 3 cross sections are an inswept arc area is pushed this grate unit 13 half side grogs at the grate unit place of next ladder; When oar formula pushing block 3 counterclockwise during the identical angle of counter-rotating, again this grate unit 13 other half side grogs are pushed to the grate unit place of next ladder, the grog in the grate unit 13 at each ladder place promotes in this way, realizes the conveying of the grog of whole grate bed.
