Abstract
The present invention relates to a roller kiln which uses coal as fuel. The present invention is characterized in that a combustion chamber is arranged on the side surface of a kiln body; flues are arranged on a roller way. The heat quantity of the coal directly acts on the roller way through the upper flue and the lower flue, and thus, the present invention solves the problem that the temperatures on the upper part and the lower part of the roller way are different. Thus, the roller kiln provided by the present invention increases heat conduction surfaces of the flues, enhances heat utilization rate, uses coal to burn and reduces burning cost. In addition, the present invention with the structure can provide possibility for multilayer roller kilns which take coal as fuel, and thus, the production capacity of the device is enhanced.
Description
The present invention relates to a kind of is the roller kilns of fuel with the coal.
Known is the roller kilns of fuel with the coal, combustion chamber and flue are arranged on the below of roller-way, and this causes combustion chamber and flue with a hot conducting surface is only arranged between the roller-way on the one hand, and heat utilization efficiency is low, also cause roller-way temperature difference great disparity up and down on the other hand, do not reach the burning process requirement.At a back problem.The measure of taking at present is provided with electric heater unit above roller-way, this has not only increased electric consumption, and has improved greatly and fired cost, therefore, the roller kilns energy consumption height of this coal electricity combination, and can only be the individual layer roller kilns, limited the raising of equipment capacity.
The purpose of this invention is to provide and a kind ofly all fire with coal, and the roller kilns that all are improved largely of heat utilization efficiency and production capacity.
Solution of the present invention is the side that the combustion chamber is arranged on roller kilns kiln body, and flue also is set above roller-way, and the combustion chamber is with being communicated with by bocca between the flue.
Below in conjunction with accompanying drawing, content of the present invention is described in further detail.
The accompanying drawing of this specification has:
Fig. 1: the vertical vertical sectional view of kiln body of the present invention;
Fig. 2: A-A cutaway view;
Fig. 3: B-B cutaway view;
Fig. 4: C-C cutaway view;
Fig. 5: D-D cutaway view.
Roller kilns of the present invention are made up of kiln body (1), body of heater (2) and chimney (3) three parts, and body of heater (2) and chimney (3) are located at the same side of kiln body (1), and the chain drive in the transmission device is arranged in the another side of kiln body (1).This chain drive comprises sprocket wheel (5) and the chain (6) that is installed in roll shaft (4) axle head, and transmission device is made up of motor, reduction box and chain drive.Roll shaft (4) is bearing in by bearing on the both sides kiln wall of kiln body (1), and the roll shaft (4) that numerous horizontal cross are provided with is promptly formed the conveyer line that places in the roller-way (7).Kiln body (1) divides preheating clinkering zone and salband two parts, and the flue (8) of three levels is set in the preheating clinkering zone from top to bottom, forms roller-way (7) between last lower flue (8).Article three, flue (8) forms two layers of roller-way (7), in like manner, sets up the roller kilns structure that flue also can form more multi-layered roller-way.Be provided with combustion chamber (9) in the body of heater (2), and be communicated with three flues (8) by three boccas (10) on the kiln wall, the same chimney in other end (3) of flue (8) is linked up.Place the kiln wall temperature of combustion chamber part very high, be located at roll shaft bearing lubrication condition and maintenance condition extreme difference in this part kiln wall, in order to address this problem, this part bearing can adopt graphite alloy bearing (11), and is fixed on the water pipe (12), this part water pipe (12) can be taken extraction apart from pipeline, so that the maintenance of graphite alloy bearing (11) in addition, feeds the cooling water of circulation in the pipeline, both can reduce the temperature of bearing, can provide hot water again.The structure of flue (8) has two characteristics: the one, be provided with next door (13) and gate (14) in the flue (8), adjacent next door forms smoke-box between (13), the pulling gate, can regulate the flow direction and the flow of flue gas in the smoke-box, thereby the temperature of control smoke-box, make the Temperature Distribution of whole piece flue reasonable, form the heating curves that meets the burning process requirement.The 2nd, at the appropriate location of flue (8) vent stack in parallel, this vent stack is made of the peaceful vent stack of perpendicular vent stack (15) (16), be provided with gate (17) on the horizontal flue that is communicated with flue (8) and perpendicular vent stack (15), the same chimney in other end (3) of flat vent stack (16) is linked up.The effect of vent stack is when whole piece flue (8) when temperature is too high, and by starting gate (17), the part of smoke of releasing descends the temperature of flue (8), and the aperture of gate (17) can be controlled the cigarette amount of letting out.The same with known roller kilns, at the top of kiln body (1) roller-way (18) that is exclusively used in oven dry also can be set, the heat of roller kilns is further utilized.
The roller kilns of indication of the present invention can reach following good effect:
1. realize the design of multilayer flue in the kiln body, the hot conducting surface of flue is increased, improved heat utilization efficiency.
2. coal-fired heat is directly on the roller-way by upper lower flue effect, temperature differs greatly about having solved known roller kilns roller-way take coal as fuel, the problem of essential additional other heater, therefore, this roller kilns can all be fired with coal, reduce and fire cost.
3. this structure for the coal be the design of the multilayer roller kilns of fuel provide may, thereby improved the production capacity of equipment.
Claims (2)
- It is 1, a kind of that what be made up of kiln body, body of heater and chimney is the roller kilns of fuel with the coal, be provided with roller-way and the flue that is positioned at the roller-way below in the kiln body, be provided with the combustion chamber in the body of heater, be provided with in the roller-way by bearing and be bearing in roll shaft on the kiln body two side, roll shaft is rotated by actuator drives, the invention is characterized in: described combustion chamber (9) are arranged on the side of kiln body (1), and the top of roller-way (7) also is provided with flue (8), are communicated with by bocca (10) between the same flue in combustion chamber (9) (8).
- 2, according to claim 1 is the roller kilns of fuel with the coal, it is characterized in that: set roll shaft bearing is graphite alloy bearing (11) in the kiln wall of combustion chamber part, and this graphite alloy bearing (11) is fixed on can be from the water pipe (12) of sidewall of combustion chamber extraction.
