Technical Field

[0001] The present application relates to the technical field of calcium oxide production, and specifically discloses a disc ash discharging machine for calcium oxide production. Background Art

[0002] The disc ash discharger is a common ash handling equipment used in lime kiln production. It is usually installed at the bottom of the lime kiln. The lime ash processed from the original lime kiln falls from the bottom of the lime kiln onto the disc ash discharger and is transferred and collected by the centrifugal force of the disc ash discharger structure, thus completing the processing of the lime ash. The normal operation of the disc ash discharger directly affects the quality and integrity of the ash. The disc ash discharger is mainly composed of a motor, a reducer, a transmission shaft, a turntable, a scraper and other components.

[0003] The scraper height of the existing disc ash discharger is generally a fixed value, which makes it inconvenient to quickly scrape the inner wall of the kiln at different heights. Therefore, in view of this, the inventor provides a disc ash discharger for calcium oxide production to solve the above problem. Utility Model Content

[0005] The ash discharging pipe is connected with the ash discharging pipe on the mounting frame, and the discharging disc is rotatably connected with the top of the ash discharging pipe and is located below the bottom of the lime kiln. The top surface of the discharging disc is evenly provided with a plurality of limiting support rods for abutting against the outer side of the bottom of the lime kiln and being rotatable around the outer side of the bottom of the lime kiln. The top surface of the discharging disc is provided with a guide cone located directly below the bottom of the lime kiln. The top surface of the discharging disc is also provided with a plurality of discharge grooves located between the guide cone and the limiting support rod and connected to the ash discharging pipe. The discharging disc is provided with a scraping mechanism for scraping the lime ash on the surface of the discharging disc and the guide cone into the ash discharging pipe. The mounting frame is provided with a driving member for driving the discharging disc to rotate. The connecting end of the ash discharging pipe and the discharge groove is provided with a micro-pressure dust suction mechanism for sucking the lime ash from the discharge groove into the inside of the ash discharging pipe.

[0006] The principles and effects of this basic solution are:

[0007] 1. The utility model provides a mounting frame and a limiting support rod to facilitate the installation and positioning of the discharging disc, which improves the stability of the structure and ensures the normal operation of the discharging disc. By providing a scraping mechanism, the lime ash on the discharging disc is scraped into the discharging chute, thereby improving the efficiency of discharging and collecting the lime ash.

[0008] 2. Compared with the prior art, the utility model is convenient for forming negative pressure airflow in the material discharge trough by setting a micro-pressure dust suction mechanism, which can not only accelerate the discharge of lime ash materials falling on the surface of the discharging disc of the lime kiln into the ash discharge pipe for collection, but also can suck in the lime ash materials lifted above the discharging disc through the negative pressure airflow, thereby making the collection of lime ash materials more convenient and more efficient, and solving the problem that when the lime ash materials are discharged from the bottom of the traditional lime kiln, the lime ash materials are easy to raise dust above the disc ash discharger, making it inconvenient for the disc ash discharger to collect the lime ash materials falling on its surface.

[0009] Furthermore, the mounting frame includes a lateral support frame symmetrically and detachably connected to the outer side of the bottom of the lime kiln and a transverse support frame installed between the two symmetrical lateral support frames, and the side of the ash discharge pipe is fixedly connected to the transverse support frame. By providing the transverse support frame, it is convenient to provide structural support and installation sites for the discharge disc, and by providing the lateral support frame, it is convenient to connect and install the transverse support frame and the structure of the discharge disc to the bottom of the lime kiln.

By setting up a motor drive, the power is transmitted and driven to rotate the bevel gear after being decelerated by the gear reducer, and the meshing connection between the bevel gear and the bevel gear ring is utilized to drive the rotation of the discharge disc, and finally the rotation of the discharge disc is utilized to provide a driving force for the lime ash material on the discharge disc to be discharged.

[0011] Furthermore, the scraping mechanism includes a fixed frame arranged at the top of the ash discharging pipe, a fixed rod arranged on the fixed frame and passing through the discharging disc to the outer top of the guide cone, and a scraping rod fixed at the top of the fixed rod and capable of scraping the outer surface of the guide cone, and the discharging disc and the guide cone can both rotate around the fixed rod. By providing the scraping rod and the fixed frame and the fixed rod installed on the ash discharging pipe, the scraping rod is fixed by the fixed frame and the fixed rod, and in the process of the discharging disc rotating around the fixed rod, the scraping rod scrapes the lime ash on the surface of the discharging disc, thereby accelerating the speed at which the lime ash enters the ash discharging pipe, and improving the collection efficiency of the lime ash.

[0012] Furthermore, the fixing frame includes a fixing platform and a plurality of connecting rods evenly arranged between the fixing platform and the inner side of the top end of the ash discharge pipe, the fixing rods are fixed on the fixing platform, and a gap is provided between two adjacent connecting rods for allowing the lime ash to pass through.

[0013] Furthermore, the micro-pressure dust suction mechanism includes an exhaust fan installed on the inner wall of the ash discharge pipe and a dust suction motor for driving the exhaust fan to rotate. By arranging the dust suction motor to drive the exhaust fan to rotate, a micro-negative pressure airflow is formed in the ash discharge pipe from the end where the discharge disc is located to suck inward, thereby collecting external dust, thereby reducing the amount of dust at the bottom of the lime kiln and on the discharge disc, and improving the work efficiency of sucking lime ash from the discharge disc into the ash discharge pipe.

A scraping mechanism is installed on the disk 4 for scraping the lime ash on the surface of the discharge disk 4 and the guide cone 6 into the ash discharge pipe 3, and a driving member is provided on the mounting frame 2 for driving the discharge disk 4 to rotate. A micro-pressure dust suction mechanism is provided at the connecting end of the ash discharge pipe 3 and the discharge groove 7 for sucking the lime ash from the discharge groove 7 into the ash discharge pipe 3, wherein the micro-pressure dust suction mechanism includes an exhaust fan 8 installed on the inner wall of the ash discharge pipe 3 and a dust suction motor 9 for driving the exhaust fan 8 to rotate, wherein the outlet end of the ash discharge pipe 3 is connected to an existing lime ash collection and containing device for collecting and storing the lime ash.

[0020] The mounting frame 2 includes a lateral support frame 10 symmetrically and detachably connected to the outer side of the bottom of the lime kiln 1 and a transverse support frame 11 installed between the two symmetrical lateral support frames 10, and the side of the ash discharge pipe 3 is fixedly connected to the transverse support frame 11.

[0021] The scraping mechanism includes a fixed frame arranged at the top of the ash discharge pipe 3, a fixed rod 18 arranged on the fixed frame and passing through the discharge disc 4 to the outer top of the guide cone 6, and a scraping rod 19 fixed at the top of the fixed rod 18 and capable of scraping the outer surface of the guide cone 6.

[0023] Compared with the prior art, the utility model provides a micro-pressure dust suction mechanism, in which the dust suction motor 9 drives the exhaust fan 8 to rotate, thereby forming a negative pressure airflow from the discharge slot 7 to the ash discharge pipe 3, which can not only accelerate the discharge of the lime ash material dropped on the surface of the discharge disc 4 of the lime kiln 1 into the ash discharge pipe 3 for collection, but also can suck in the lime ash material lifted above the discharge disc 4 through the negative pressure airflow, thereby making the collection of the lime ash material more convenient and more efficient. By providing a fixed platform 17 and a connecting rod 20, the fixed rod 18 is supported and fixedly installed to make the structure more stable, thereby solving the problem that when the traditional lime kiln is discharged from the bottom, the lime ash material is easy to generate dust above the disc ash discharger, which is inconvenient for the disc ash discharger to collect the lime ash material dropped on its surface.
