Description

Technical Field

[0001] The utility model relates to the technical field of lime production, in particular to a vertical kiln for lime production. Background Art

[0002] After long-term use, a lot of impurities will be deposited in the smoke exhaust pipe outside the existing lime production vertical kiln, causing the inner diameter of the smoke exhaust pipe to shrink and the smoke exhaust efficiency to be low. The inner diameter of the smoke exhaust pipe needs to be restored regularly by manual cleaning, which increases the labor intensity of workers and has low work efficiency, making it difficult to meet usage needs. For this reason, we propose a lime production vertical kiln to solve the problems raised in the above background technology. Utility Model Content

[0003] The utility model aims to provide a vertical kiln for lime production to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vertical kiln for lime production, comprising a vertical kiln body, a smoke exhaust pipe interconnected with the top of the vertical kiln body fixedly connected, a column fixedly installed on the top of the vertical kiln body and corresponding to the right side of the smoke exhaust pipe, a collar rotatably connected to the column, the inner side of the collar movably connected to the surface of the column through a limit rotating block, a bracket fixedly connected to the left side of the collar through a cross bar, and a cleaning component fixedly connected to the position of the top of the inner wall of the bracket corresponding to the smoke exhaust pipe through an electric telescopic column.

[0005] Furthermore, a plurality of gear teeth are installed around the outer side of the collar at equal distances, a horizontal plate is fixedly installed on the right side of the column, a stepper motor is fixedly installed on the bottom of the horizontal plate, and the output shaft of the stepper motor passes through the outside of the horizontal plate and is fixedly connected to a driving gear used in conjunction with the gear teeth.

[0006] Furthermore, the cleaning assembly includes a circular plate and a connecting ring, the circular plate and the connecting ring are fixedly connected via four connecting rods, the circular plate is fixedly connected to the bottom end of the electric telescopic column, and a scraper is fixedly connected to the outer side of the connecting ring.

[0007] Furthermore, a plurality of rolling elements are movably mounted on the top and bottom of the position-limiting rotating block, and the rolling elements are specifically balls.

[0008] Furthermore, the top and bottom of the cross bar on the outer side of the bracket are fixedly connected with reinforcing ribs, and the side of the reinforcing rib close to the cross bar is fixedly connected to the cross bar.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The utility model can start the electric telescopic column to drive the circular plate to move downward when the inner wall of the smoke exhaust pipe on the top of the vertical kiln body needs to be cleaned, and the scraper on the outer side of the connecting ring is used to scrape off the impurities deposited on the inner wall of the smoke exhaust pipe under the connection of the connecting rod. After completion, the electric telescopic column drives the cleaning component to return to its position, and then starts the stepper motor to drive the driving gear to rotate with its output shaft. The gear teeth meshing with it can drive the sleeve ring to rotate under the connection of the limit rotating block and the column, and then rotate the bracket and the cleaning component to the other side to prevent the normal smoke exhaust work of the smoke exhaust pipe. The vertical kiln for lime production has a reasonable structural design and is easy to use. When impurities are deposited in the smoke exhaust pipe of the vertical kiln for a long time, automatic scraping and cleaning can be realized without too much manual operation, which effectively reduces the labor intensity of workers and improves efficiency, thereby ensuring the normal smoke exhaust work of the vertical kiln.
