Description

Technical Field

[0001] The utility model relates to the field of lightweight aggregates, and in particular to a rotary temperature-regulating kiln structure. Background Art

[0002] The Chinese invention with patent application number 201010240962.6 discloses a method for manufacturing energy pellets using instantaneous temperature jump sintering. The preparation steps include an instantaneous temperature jump step, and the temperature in the kiln instantly jumps from 200-400°C to 700-900°C. To realize this process, the sintering material needs to be able to be quickly transmitted in two kiln bodies with different temperatures during the transmission process, and at the same time, a large temperature difference must be ensured between the two kiln bodies to achieve the instantaneous temperature jump sintering process.

[0003] In response to this process requirement, a Chinese invention patent with a patent application number of 201010288822.6 discloses a kiln structure with adjustable temperature, in which a temperature-adjusting chamber is connected to the middle section of a strip-shaped kiln body, wherein the strip-shaped kiln body includes a feed kiln body and a discharge kiln body, and the outlet end of the feed kiln body and the inlet end of the discharge kiln body are respectively connected to the temperature-adjusting chamber; in this embodiment, the strip-shaped kiln body is a curved kiln body, and can also be a straight kiln body. The temperature-adjusting chamber includes at least one exhaust port and at least one air inlet, wherein the exhaust port and the air inlet can be opened or closed respectively. By controlling the closing or opening of the exhaust port and the air inlet of the temperature-adjusting chamber, the sintering temperature of the middle section of the kiln body can be effectively controlled and adjusted. In particular, by utilizing the function of the temperature-adjusting chamber, the temperature can be instantly adjusted and jumped during the sintering process, and the surface of the sintered lightweight aggregate product can be vitrified. However, it was found in actual production that the instantaneous temperature jump range of this structure is limited, and the adjustable temperature is also limited, which is somewhat different from the actual process requirements. At the same time, the process of sintering materials entering the discharging kiln body from the feed kiln body is not smooth and is prone to blockage. The feed kiln body and the discharging kiln body need to be set on the same side of the temperature control room due to volume reasons, so that the sintering materials need to turn around when using gravity transmission to enter the discharging kiln body for sintering. A large angle turn will cause blockage at the end of the discharging kiln body, which is not conducive to the smooth transmission of the sintering materials. Utility Model Content

[0025] For example, please refer to Figure 1 As shown:

[0026] A rotary temperature-controlled kiln structure comprises a feeding kiln 100 and a combustion kiln 300 arranged on the same side of an insulation chamber 200; the feeding kiln 100 is located above the combustion kiln 300; the feeding kiln 100 and the combustion kiln 300 are arranged on the same side because when the device is used to sinter energy pellets, the feeding kiln 100 and the combustion kiln 300 have a long length. If they are arranged on both sides, the overall occupied area of ​​the device will be greatly increased. Therefore, for the purpose of saving space and reducing costs, it is preferred to place the feeding kiln 100 and the combustion kiln 300 on the same side. 00 is arranged on the same side as the combustion kiln 300; the sintered material 400 entering through the feeding kiln 100 is turned around by gravity through the rotating structure 201 arranged in the insulation chamber 200 and then enters the combustion kiln 300; the feeding port 310 of the combustion kiln 300 is arranged at an interval outside the insulation chamber 200 at the discharge port of the rotating structure 201; the rotating structure 201 is used to reverse the sintered material 400, and use gravity to make the sintered material 400 in the rotating structure 201 Smooth sliding; the rotary structure 201 includes a first transmission part 210, a second transmission part 220, and a third transmission part 230 which are connected in sequence and tilted in the direction of gravity. After being connected in this way, each transmission part of the rotary structure 201 is tilted in the direction of gravity, so that the sintered material 400 can pass through the transmission part in sequence and move downward under the action of gravity; the first transmission part 210 is fixedly connected to the feeding kiln 100; the discharge port of the third transmission part 230 is arranged opposite to the feeding port 310 of the combustion kiln 300; the three-stage structure is used for transmission, which can increase the movement path of the sintered material, and at the same time, multiple reversals are used to realize the steering of the sintered material 400. Compared with the one-time steering in the original scheme, congestion can be better avoided. Since the weight of the sintered material itself is not large, congestion is prone to occur in the V-shaped tube or similar structure using one-time steering; and multiple steering can reduce the turning angle each time and provide more buffer space, thereby effectively avoiding congestion;

[0027] In one embodiment of the utility model, the angle between the first transmission part 210 and the second transmission part 220 is greater than or equal to 90°; the angle between the second transmission part 220 and the third transmission part 230 is greater than or equal to 90°; when the angle between two adjacent transmission parts is larger, the transmission is smoother, and in order to achieve rotation, the angle is not allowed to be too large. Usually, when the angle is greater than 90°, blockage can be avoided. In order to further increase the angle, the angle between the two adjacent transmission parts can be appropriately adjusted by changing the angle between the feeding kiln 100 and the combustion kiln 300.

[0028] In one embodiment of the present invention, the first transmission part 210 is connected to the middle part of the second transmission part 220 to form a first temporary storage part 221 for temporarily accommodating the sintering material 400 at the high end of the second transmission part 220; the second transmission part 220 is connected to the middle part of the third transmission part 230 to form a second temporary storage part 231 for temporarily accommodating the sintering material 400 at the high end of the third transmission part 230; by adding the first temporary storage part 221, the possibility of blockage can be further reduced. When the sintering material 400 enters the second transmission part 220 from the first transmission part 210, if the sintering material 400 descends too fast, it will still be partially stacked at the corner. Through the first temporary storage part 221, the stacked sintering material 400 can be squeezed or impacted and then enter the first temporary storage part 221, thereby reducing the accumulation of the sintering material 400 between the first transmission part 210 and the second transmission part 230. The sintered material 400 at the connection between the two transmission parts 220 can further reduce the occurrence of congestion; similarly, the second temporary storage part 231 has the same function; the first transmission part 210, the second transmission part 220, and the third transmission part 230 are all straight open semi-cylindrical structures; usually an open semi-cylindrical structure is set for transmission, which can achieve more contact area between the sintered material 400 and the air, so that the heat of the sintered material 400 can be better dissipated into the insulation room 200; the high ends of the second transmission part 220 and the third transmission part 230 are both provided with end sealing plates 240; the high end refers to the highest end of the second transmission part 220 and the third transmission part 230; the purpose of setting the end sealing plate 240 is to prevent the descending sintered material 400 from falling from the high end when colliding and squeezing with the transmission part, and to achieve a semi-closed effect through the end sealing plate 240.

[0029] In one embodiment of the present invention, the third transmission part 230 passes through the side wall of the insulating chamber 200 and continues to extend outward to have a discharge part 250; the feed port 310 of the combustion kiln 300 is arranged opposite to the discharge part 250; the combustion kiln 300 is arranged at an interval on the outside of the insulating chamber 200, so the feed port 310 of the combustion kiln 300 is not directly connected to the insulating chamber 200; the feed port 310 is arranged relative to the discharge part 250, and the sintered material 400 flies into the feed port 310 after coming out of the discharge part 250. By setting the discharge part 250, the interval between the feed port 310 and the insulating chamber 200 can be increased, thereby reducing the influence of the high temperature in the combustion kiln 300 on the insulating chamber 200, ensuring a high temperature difference between the combustion kiln 300 and the insulating chamber 200, so that the sintered material 400 can enter the feed port 310 from the discharge part 250 to achieve an instantaneous temperature jump.

[0030] In one embodiment of the utility model, the insulation room 200 includes at least one exhaust port 260 and at least one air inlet 270; the exhaust port 260 and the air inlet 270 can be opened or closed respectively; the exhaust port 260 is provided with an exhaust cover 261, and the exhaust cover 261 can open or close the exhaust port 260; the air inlet 270 is provided with an air inlet cover 271, and the air inlet cover 271 can open or close the air inlet 270; by adjusting the opening and closing of the air inlet cover 271 and the exhaust cover 261, the The temperature of the insulating chamber 200 can be controlled, so as to better ensure the temperature inside the insulating chamber 200; a water reservoir 280 for absorbing the heat of the insulating chamber 200 is disposed on the top of the insulating chamber 200; the exhaust vent 260 is disposed through the water reservoir 280; the heat of the insulating chamber 200 is transferred to the water reservoir 280 through the exhaust vent 260, so as to avoid the temperature of the insulating chamber 200 being too high, and the heat of the sintered material 400 and the insulating chamber 200 can be effectively utilized for resource utilization and cost saving.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
