Abstract
Description
Technical Field
[0001] This application relates to the technical field of kilns, and particularly relates to a device for preventing ash accumulation and purging in the cones of a double-C kiln. Background Art
[0002] The double-C kiln, also known as an annular shaft kiln, consists of two kiln chambers and can be used to calcine dolomite and limestone. Its lower part is composed of two cones, with a connecting channel in the middle. The air flow passes through the connecting channel for heat exchange. There is an ash discharge funnel below the connecting channel. During the passage of the air flow, powder will be mixed and precipitated into the ash removal funnel. During use, the ash discharge funnel is prone to ash accumulation. Since the inside of the kiln is in a high-temperature state, it cannot be cleaned. As time goes by, more and more ash accumulates, which will cause the channel to be blocked, thereby affecting the flow of the air current, resulting in underburned products and a relatively large fuel consumption. In addition, ash will also accumulate on the cones inside the kiln, which cannot be cleaned, affecting the downward flow of lime. It will also affect the upward flow of the cooling air, resulting in a higher ash discharge temperature and greater damage to the equipment. Utility Model Content

[0019] Now, the present application will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, which only illustrate the basic structure of the present application in a schematic manner, so they only show the components related to the present application.
[0020] As shown in Figures 1-5As shown in the figure, a device for preventing ash accumulation and purging in a double-C kiln cone volume includes a kiln chamber. At the bottom of the kiln chamber, there are two wind cap cones 1. An ash discharge funnel 2 is formed between the two wind cap cones 1. Inside the wind cap cone 1, there are a first cooling air duct 3 and a second cooling air duct 4. One end of the first cooling air duct 3 is opened in the ash discharge funnel 2, and the other end of the first cooling air duct 3 is connected to the corresponding compressed air tank 5. One end of the second cooling air duct 4 is opened at the end of the wind cap cone 1 facing away from the ash discharge funnel 2, and the other end of the second cooling air duct 4 is connected to the corresponding compressed air tank 5.
[0021] Cold air can be introduced into the first cooling air duct 3 and the second cooling air duct 4 to cool the wind cap cone 1 while removing ash, reducing damage to the equipment.
[0022] By arranging the first cooling air duct 3 and the second cooling air duct 4 on the wind cap cone 1, the ash accumulated in the wind cap cone 1 and the ash discharge funnel 2 can be cleaned without stopping the kiln, reducing the problem of poor product quality caused by ash accumulation blocking the air flow and also solving the problem of fuel waste caused by blockage.
[0023] In some further embodiments, electric valves 6 are provided on both the first cooling air duct 3 and the second cooling air duct 4.
[0024] The electric valves on the first cooling air duct 3 and the second cooling air duct 4 can be switched on and off correspondingly through corresponding programs (such as PLC programs). Exemplarily, the first cooling air ducts 3 on the two wind cap cones 1 can be set to blow air alternately or at intervals, so as to form a certain impact force on the ash accumulated on the ash discharge funnel 2, thereby improving the treatment effect on the ash.
[0025] In some further embodiments, a vibration motor 11 is provided inside the side wall of the wind cap cone 1 facing the ash discharge funnel 2. A vibration frame 13 is provided on the side wall of the wind cap cone 1 facing the ash discharge funnel 2, and the vibration frame 13 is connected to the vibration motor 11.
[0026] The vibration motor 11 is located inside the wind cap cone 1 and is connected to the external vibration frame 13 through a connecting rod 12. Specifically, a cavity 10 is opened inside the wind cap cone 1, the vibration motor 11 is arranged inside the cavity 10, a slot is provided on the wind cap cone 1, one end of the slot communicates with the cavity 10, and the other end is connected to the ash discharge funnel 2. The connecting rod 12 is arranged in the slot, with one end connected to the vibration motor 11 and the other end connected to the vibration frame 13.
[0027] Under the action of the vibration motor 11, the vibration frame 13 can shake off the ash on the side wall of the ash discharge funnel 2. At the same time, with the cooperation of the air flow impact, ash removal can be better carried out to avoid blockage.
[0028] In some further embodiments, the vibrating rack 13 is of a net structure, and the cross-section of the mesh bar 130 of the vibrating rack 13 is diamond-shaped.
[0029] The mesh bar 130 with a diamond-shaped cross-section can produce a "cutting" effect on the accumulated ash. For some accumulated ash that is about to or has already caked, simple air flow impact may not be able to clean it thoroughly. By setting the vibrating rack 13 and treating the accumulated ash through direct contact force, efficient cleaning of the caked accumulated ash can be ensured.
[0030] In some further embodiments, the air outlet of the first cooling air duct 3 on one of the wind cap cones 1 faces the vibrating rack 13 on the other wind cap cone 1, and the first cooling air duct 3 on the other wind cap cone 1 faces the vibrating rack 13 on one of the wind cap cones 1.
[0031] The air outlets of the first cooling air ducts 3 on the two wind cap cones 1 blow towards the corresponding vibrating racks 13 in a staggered manner, so that the treatment processes of the two for the accumulated ash are carried out simultaneously, further ensuring the treatment effect on the accumulated ash.
[0032] In some further embodiments, a bent pipe is provided at the air outlet of the second cooling air duct 4, and the air outlet of the bent pipe faces one side wall of the wind cap cone 1 that is opposite to the ash discharge funnel 2.
[0033] In some other embodiments, a bent pipe can be provided at the air outlet of the second cooling air duct 4 to make the air flow blow towards the wind cap cone 1 itself, so as to facilitate blowing the accumulated ash.
[0034] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
