The noun of locality such as forward and backward, upper and lower that this paper is related is to be that benchmark defines with the working direction of pellet in system, before the position of pellet elder generation process is, after through the position be after.The noun of locality that should be appreciated that herein to be adopted should not limit the protection domain of this patent.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Please refer to Fig. 1 and Fig. 2, Fig. 1 carries the structural representation of a kind of embodiment of pellet heater for multi-head spiral that the utility model provides; Fig. 2 is that multi-head spiral shown in Figure 1 carries the A of pellet heater to view.
Multi-head spiral provided by the utility model is carried the pellet heater, is used for pellet and goes into kiln system pellet is heated.This multi-head spiral carries the pellet heater to comprise at least two row's worm conveyors 1, and by the above worm conveyor 1 conveying pellet 2 of two rows, pellet 2 is fully heated in high temperature gas flow passage 3, make the temperature of pellet 2 before going into kiln obtain bigger raising, can save the firing rate in the glass melter, reach purpose of energy saving, also improve economic benefit of enterprises simultaneously.Worm conveyor 1 is in the process of carrying pellet 2, and pellet 2 can move on conveying belt always, can not turn over the shattering material, can effectively reduce the possibility of pellet 2 fragmentations, guarantees the quality of pellet 2.And the above worm conveyor 1 of two rows can significantly increase heated pellet 2 quantity in high temperature gas flow passage 3 simultaneously, improves the heating efficiency of pellet 2, and that also improves pellet 2 simultaneously goes into kiln efficient.
In a kind of concrete embodiment, multi-head spiral provided by the utility model is carried and can be comprised in the pellet heater that two drain into eight row's worm conveyors 1, and every row has four to eight row worm conveyors 1, the worm conveyor battle arrays of the many rows of formation multiple rows.Go in the kiln system at pellet, multi-head spiral carries the front end of pellet heater to be provided with pellet multiply dispenser, be provided with the structure in the pellet multiply dispenser to such an extent that carry the pellet heater suitable with multi-head spiral, make an inlet of every worm conveyor just in time corresponding with an outlet of pellet multiply dispenser, pellet multiply dispenser distributes each strand pellet 2 that obtains to enter just in the worm conveyor 1, forms the matching structure of system.
Obviously, above-mentioned many rows multiple row worm conveyor battle array, the structure of its quantity can as long as distribute function effectively to cooperate with the pellet multiply, just can satisfy requirement of the present utility model according to producing the needs setting.
Particularly, can be more than 6 meters with the Design of length of worm conveyor 1, be about to worm conveyor commonly used 1 and prolong, to prolong the heat exchanger time between high temperature gas flow and the pellet, make pellet fully absorb the heat of high temperature gas flow, improve the temperature of pellet.
Need to prove that long worm conveyor 1 can not be connected to form with the worm conveyor 1 of several weak points.Simultaneously, this sentences the length direction of the working direction of pellet as worm conveyor 1.
A kind of preferred embodiment in, the gas in the high temperature gas flow passage 3 can be the waste gas of glass melter.Utilize the waste gas in the glass melter that pellet 2 is heated, make full use of the waste heat of waste gas in the glass melter, the firing rate when significantly reducing pellet 2 heating improves economic benefit of enterprises.And if waste gas directly enters atmosphere, its higher temperature also can cause bad influence to environment, utilize waste gas that pellet 2 is entered heating after, the temperature of waste gas reduces, and helps protecting environment, further improves the effect of energy-saving and emission-reduction.
Further, heat conductivility good metal dividing plate can be set between high temperature gas flow passage 3 and pellet 2, promptly utilize metal partion (metp) that pellet 2 and waste gas are separated, avoid exhaust emission pellet 2, pyritous waste gas is with heat transferred heat conductivility good metal dividing plate, metal partion (metp) is heat transferred pellet 2, thereby on the basis of guaranteeing pellet 2 quality, improved the temperature of pellet 2.Obviously, metal partion (metp) can also be other plate object with good heat conductive performance, as long as can separate waste gas and pellet 2, and the heat transferred pellet 2 of waste gas just can be able to be satisfied requirement of the present utility model.
In technical scheme further, multi-head spiral provided by the utility model is carried in the pellet heater, and the inlet M of high temperature gas flow passage 3 is located at the below of worm conveyor 1, and outlet N is located at the top of worm conveyor 1.According to the natural law, gas flow temperature has the trend that flows downward when reducing; Multi-head spiral of the present utility model is carried in the pellet heater, and behind the high temperature gas flow admission passage, with pellet 2 heat exchange, temperature reduces, and has the trend that moves downwards.Inlet is located at the below of worm conveyor 1, and the top that worm conveyor 1 is located in outlet can make air-flow carry the time sufficiently long that stops in the pellet heater with multi-head spiral, makes pellet 2 fully attract the heats of air-flows, improves the heats of pellet 2.
Except above-mentioned multi-head spiral is carried the pellet heater, the utility model also provides a kind of pellet of above-mentioned multi-head spiral conveying pellet heater that comprises to go into kiln system, and the structure that this pellet is gone into other each several parts of kiln system please refer to prior art, and this paper repeats no more.
More than pellet provided by the utility model gone into kiln system and multi-head spiral thereof carry the pellet heater to be described in detail.Used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
