Abstract
The self-concurrent-heating kiln for firing bricks features that a self-concurrent-heating channel by the main flue at the top of kiln is connected via control valve and branch pipes to coal charge holes of each kiln chamber to deliver the afterheat into drying kiln chamber before preheating region and moisture is discharged via main flue. Its advantages include less investment for reformation, high thermal utilization rate, and speeding-up burning-up of bricks.
Description
The present invention relates to a kind of baking bricks and use ring type self concurrent heating kiln.
In the process of producing clay brick, adobe needs just can go into the kiln roasting after drying.Drying means has two kinds of artificial drying and air dries.Artificial drying is carried out in a hothouse, need to be equipped with drying cart, air-introduced machine, moisture-eliminating blower and to add equipment such as gas boiler.Heat is taken from the waste heat of annular kiln insulation, cooling section, carries by one the tens meters long defeated passage of heat.Air dry is carried out on the base field in the open.Obviously air dry is subjected to the weather conditionality, and the waste heat of annular kiln can not make full use of.But the investment of artificial drying is bigger, builds one group of hothouse and needs about 2,000,000 yuan approximately, and this is that general middle-size and small-size brick field is to be difficult to bear.
The objective of the invention is to disclose a kind of type self concurrent heating kiln, can make full use of the space and the waste heat of annular kiln self, before the adobe preheating, make base substrate reach dry requirement.
Task of the present invention is achieved in that the side at annular kiln kiln top flue collector, an annular is set from the concurrent heating passage, is connected with arm through the control lock between the coal feeding hole of this passage and each firing chamber.
Usually, described defeated hot leg pipe is communicated with the coal feeding hole that is located at the middle part, firing chamber, avoids the cooling of both sides, heat supply firing chamber too fast; Each firing chamber is provided with a control lock with main from the concurrent heating interchannel.
The operation principle of this annular kiln is in the waste heat of the firing chamber of insulation belt and salband after with roasting, arm input through being communicated with this chamber is from the concurrent heating main channel, and be in before the preheating zone dry firing chamber through the arm of this chamber obtain the waste heat of confession, during operation, dry firing chamber also need open flue damper, allow flue collector be connected with the air port, Kazakhstan of this chamber, moisture discharges from flue collector.Because this heat supply concerns ringwise with the position that is heated, so be referred to as the meaning annular from concurrent heating.
Major advantage of the present invention is:
1, realizes the artificial drying of adobe with extremely low investment, only several thousand yuan of improvement expenseses.
2, improve the afterheat utilization rate.Because the waste heat transfer passage is shorter than the defeated hot road of common artificial hothouse, so thermal losses is low, the heat energy utilization rate can improve about 30%.
3, can improve the fiery line speed of annular kiln.Because brick bat drying is thorough before the preheating, base substrate temperature height, fiery line speed can bring up to for 1.30 row/times from 1.10 row/times of past, increased output about 25%.
With embodiment and accompanying drawing the present invention is specified below.
Fig. 1 is the annular kiln schematic diagram.
Fig. 2 is the annular kiln cutaway view.
Fig. 3 is from the concurrent heating manifold configuration.
Firing chamber 1, flue collector 2, flue 3, branch flue 4, air port 5, Kazakhstan, coal feeding hole (being commonly called as pinkeye) 6 constitute the major part of annular kilns among the figure.The present invention is provided with one from concurrent heating main channel 10 at Yao Ding, and it is communicated with the coal feeding hole 6 of each firing chamber by outer shroud arm 11, is provided with control lock 12 at arm 11 and between concurrent heating main channel 10.
From brick the overarching of concurrent heating main channel 10 usefulness, high 70cm, wide 80cm.Arm 11 is the tree fork shape special pipe, one end of its main pipe 13 through described control lock 12 be connected from the concurrent heating main channel, usually, the coal feeding hole 6 of a firing chamber is made up of side opening 8 and two holes 9 that mediate of row that two rows are in both sides, the main pipe 13 of concurrent heating arm 6 is communicated with the interstitial hole 9 of described coal feeding hole through breeches pipe 14, to obtain the waste heat of firing chamber central authorities.Each breeches pipe 14 is tree fork shape and distributes on main pipe 13, be connected with the coal feeding hole of a firing chamber, utilizes a control lock 12 can control a corresponding firing chamber.Adobe 15 usefulness " # " expression among the figure, arrow 16 expressions are from the air-flow trend of concurrent heating.
Annular kiln dryer section mean temperature reaches 250 ℃ in the test manufacture, will improve about 80 ℃ than artificial drying room temperature, and it is about 13% to go into kiln adobe water content, and requirement in the past is 6%.On one 22 brickkiln, reconstruct, under-capitalize 2000 yuan, product qualification rate reaching 95%, annual production increases by 300 10,000 bricks, and wet base kiln collapse phenomenon does not take place.
Claims (3)
1, a kind of ring type self concurrent heating kiln is characterized in that being provided with one from the concurrent heating passage in annular kiln kiln top flue collector one side, and this passage is through control lock and from the concurrent heating arm, is communicated with the coal feeding hole of each firing chamber of annular kiln.
2,, it is characterized in that describedly being communicated with the coal feeding hole that is located at the middle part, firing chamber from the concurrent heating arm by the described ring type self concurrent heating kiln of claim 1.
3, by claim 1 or 2 described ring type self concurrent heating kilns, it is characterized in that described is the tree fork shape special pipe from the concurrent heating arm, one side of its main pipe (13) through described control lock (12) be connected from the concurrent heating main channel, its breeches pipe (14) outer end is connected with the coal feeding hole (6) of a firing chamber.
