Description

Technical Field

[0001] The utility model relates to the technical field of lime production equipment, in particular to a multi-point ash discharging device for a lime kiln. Background Art

[0002] At present, the traditional mechanized lime shaft kiln ash discharging method in China generally adopts screw cone ash discharging or disc ash discharging machine. Screw cone ash discharging is single-point ash discharging, and when the kiln condition changes, it cannot be adjusted smoothly due to single-point ash discharging. Disc ash discharging is circumferential ash discharging. When the lime kiln has uneven burning or nodules, it is difficult to make local adjustments for the uneven burning area and nodule area of the lime kiln. These two ash discharging methods bring great difficulties to operators when dealing with faults. For example, the Chinese patent discloses "a multi-point ash discharging device for a lime kiln", and its application number is: "202020999043.6". Each discharge pipe can be opened, so that the lime with uneven burning or nodules can be cleaned. Before opening the discharge pipe, the first through hole can be blocked and the conveying mechanism can be stopped, while other conveying mechanisms can continue to work. In this way, while cleaning the lime with uneven burning or nodules, other discharge pipes can continue to work. However, allowing a single discharge pipe to be opened for cleaning may lead to unevenness during the ash discharging process, affecting the overall quality stability of the lime product.

[0023] Refer to Figures 1-4, an ash discharging device with multiple points of a lime kiln in an embodiment of the present utility model includes: a kiln body 1 for accommodating limestone for high-temperature calcination to convert it into quicklime. The upper surface of the kiln body 1 is rotatably connected by a hinge to a sealing cover 4 for closing the top of the kiln body to prevent the escape of heat and harmful gases and can open the sealing cover 4 for the operation of adding limestone. The upper surface of the kiln body 1 is fixedly connected with a ventilation pipe 5 for adjusting the temperature and ventilation conditions inside the kiln body. The side surface of the kiln body 1 is rotatably connected by a rotating shaft to a protective cover 3 for being able to open the protective cover 3 for operation when it is necessary to clean the filter plate 11 or check the inside of the kiln body 1. A cleaning port is provided on the side surface of the kiln body 1 for providing a passage for cleaning and maintenance. The cleaning port is located above the filter plate 11, and the protective cover 3 covers the cleaning port. The upper surface of the sealing cover 4 and the right surface of the protective cover 3 are both fixedly connected with handles for facilitating the operator to manually open or close. The side surface of the kiln body 1 is fixedly connected with an output pipe 2 for discharging the lime filtered by the filter plate from the kiln body.

[0024] The lower surface of the kiln body 1 is fixedly connected with a motor 7 for providing power. The output end of the motor 7 is fixedly connected with a rotating shaft 8 for connecting the output end of the motor 7 and a turntable 9 to transmit the power of the motor 7. The rotating shaft 8 penetrates the lower surface of the kiln body 1. The end of the rotating shaft 8 away from the motor 7 is fixedly connected with a turntable 9 for supporting components such as the filter plate and the deflector plate to realize the filtration and diversion of lime. The inner side of the upper surface of the turntable 9 is high and the outer side is low to cooperate with the deflector plate 12 for guiding the lime. The upper end of the rotating shaft 8 is fixedly connected to the lower surface of the turntable 9. The upper surface of the turntable 9 is fixedly connected with a support column 10 for supporting the filter plate 11. The side surface of the support column 10 is fixedly connected with a deflector plate 12 for guiding the lime to the connection port of the output pipe 2 and the kiln body 1 to ensure that the lime can flow out smoothly. The deflector plate 12 is located on the upper surface of the turntable 9. The upper end of the support column 10 is fixedly connected with a filter plate 11 for filtering the lime to remove impurities and unreacted particles therein. A limiting groove is provided on the inner side wall of the kiln body 1 for limiting the moving range of the filter plate 11. The side surface of the filter plate 11 is located inside the limiting groove for preventing the filter plate from shifting. The ventilation pipe 5 and the output pipe 2 are both communicated with the kiln body 1. The connection port of the output pipe 2 and the kiln body 1 is located between the filter plate 11 and the turntable 9. The lower surface of the kiln body 1 is fixedly connected with a support for supporting the kiln body 1. The support 6 is located on the side of the motor 7.

[0025] Working principle: A certain amount of limestone is placed in the kiln body 1. After high-temperature calcination, it becomes quicklime. The sealing cover 4 and the protective cover 3 are closed respectively to ensure the sealing of the kiln body 1. The ventilation pipe 5 is used to adjust the temperature and ventilation in the kiln body. The motor 7 is in the standby state, the turntable 9 is stationary, and the filter plate 11 and the guide plate 12 also remain in place. When ash discharge is required, the motor 7 is started, which in turn drives the turntable 9 to rotate inside the kiln body 1. As the turntable 9 rotates, the filter plate 11 on the support column 10 also rotates accordingly. The function of the filter plate 11 is to filter the lime and let the qualified lime fall into the area between the turntable 9 and the filter plate 11. Above the filter plate 11 are the removed impurities and unreacted particles. The inner side of the upper surface of the turntable 9 is higher than the outer side, so that the lime is affected by the centrifugal force during rotation and moves to the outer side of the turntable 9. At the same time, the arrangement of the guide plate 12 further guides the lime to flow to the connection port of the output pipe 2 and the kiln body 1 and flows out of the kiln body 1 along the output pipe 2 for subsequent collection and processing. When it is necessary to clean the inside of the kiln body 1 or check components such as the filter plate 11, the protective cover 3 can be opened for operation through the cleaning port. At the same time, the opening of the sealing cover 4 is used to add new limestone raw materials or perform other maintenance work.
