Description

Technical Field

[0001] The utility model relates to the technical field of rotary kiln calcination, and in particular to a device for calcining and purifying manganese carbonate ore in a rotary kiln. Background Art

[0002] A rotary bed kiln, also known as a rotary kiln, is a type of building materials equipment. Rotary kilns are categorized by the materials they process, including cement kilns, metallurgical and chemical kilns, and lime kilns. Cement kilns are primarily used to calcine cement clinker and are divided into two main types: dry process and wet process. Metallurgical and chemical kilns are primarily used in the metallurgical industry for magnetization roasting of lean iron ore in steel mills; oxidation roasting of chromium and ferronickel ores; roasting of high-alumina bauxite in refractory plants and clinker and aluminum hydroxide in aluminum plants; and roasting of chromium ore sand and chromium ore powder in chemical plants. Lime kilns are used to roast active lime and light-burned dolomite for use in steel mills and ferroalloy plants.

[0003] After searching, the announcement number CN220959527U discloses an aluminum ash calcining rotary kiln, which belongs to the field of rotary kiln technology, including a kiln tail box, a base, a support platform and a fixed seat. A feed hopper is provided on the top of the kiln tail box, a dust removal pipe is provided on one side of the kiln tail box, and a dust collector is fixedly connected to the other end of the dust removal pipe. A lifting plate is fixedly connected to the bottom of the kiln tail box, and a lifting platform is fixedly connected to the bottom of the lifting plate. One side of the base is fixedly connected to an oil tank. By setting a sleeve and working with the help of a hydraulic pump, hydraulic oil is transported from the oil tank to the sleeve through the solenoid valve. With the help of the hydraulic effect, the lifting platform is pushed to move, driving the lifting plate to move, thereby driving the kiln tail box to rise and fall, thereby achieving the effect of appropriately adjusting the angle. By setting a first telescopic rod and a second telescopic rod and working with the help of an air pressure pump, the first telescopic rod and the second telescopic rod are pushed to slide, thereby pushing the telescopic tube to slide in the fixed tube, thereby achieving the effect of adjusting the combustion position.

[0004] When the above-mentioned aluminum ash calcining rotary kiln transports materials into the steel plate layer through the feed hopper, the materials cannot be transported quantitatively, which easily leads to the material not being able to be calcined evenly in the steel layer plate, thereby significantly reducing the material calcination and purification efficiency.

This design solves the problem that the material cannot be quantitatively transported in the prior art, which leads to the material being unable to be calcined evenly in the steel layer, thereby greatly reducing the efficiency of material calcination and purification.

[0027] See also Figure 2 The telescopic assembly 2 also includes an electric telescopic rod 21. The telescopic end of the electric telescopic rod 21 is fixedly connected to the baffle 22. The electric telescopic rod 21 drives the baffle 22 to complete the closing interception work at the feeding bin 11.

[0028] See also Figure 4 The drive assembly 3 also includes a motor 31, which is fixedly mounted on the side of the flow limiting bin 12. The drive assembly 3 also includes a first conical tooth 32, which is fixedly connected to the output end of the motor 31.

[0031] The working principle and use process of this utility model are as follows:

[0032] The staff can first put the first batch of materials into the feed bin 1 through the slot on the upper part of the feed bin 1. At this time, the materials with impurities will accumulate on the screening plate 51. At this time, the electric telescopic rod 21 is started so that the telescopic end of the electric telescopic rod 21 drives the baffle 22 to move up until the closing work in the cavity of the feed bin 11 is completed. At this time, the motor 31 can be started so that the output end of the motor 31 drives the first conical gear 32 to rotate.

When the second synchronous rod 42 rotates, the elliptical block 421 located on the outside of the second synchronous rod 42 will repeatedly contact the screening plate 51, and under the elastic action of the spring coil 521 at the bottom of the screening plate 51, the screening plate 51 will drive the materials accumulated on it to oscillate back and forth in the cavity of the feed bin 1. Through this design, the impurity removal work before calcination can be carried out on the materials to be calcined. This design can effectively avoid In order to prevent impurities from entering the kiln tube 6 along with the materials and thus affecting the calcination and purification efficiency, the staff then starts the electric telescopic rod 21 so that the telescopic end of the electric telescopic rod 21 drives the baffle 22 to move downward. At this time, the materials located on the upper part of the screening plate 51 will move toward the feeding bin 11 and the flow limiting bin 12 side under the action of vibration. When all the materials in this batch enter the feeding bin 11 and the flow limiting bin 12, the electric telescopic rod 21 can be started again and the baffle 22 can be driven to complete the closing and isolation of the feeding bin 11. At this time, the staff can put the second batch of materials into the feeding bin 1 and repeat the above operation. In particular, when the first batch of materials enters the feeding bin 11 and the flow limiting bin 12, under the drive of the motor 31, the first synchronous rod 34 will synchronously drive the flip plate 35 to flip in the flow limiting bin 12 until the materials flip from the flow limiting bin 12 to the left kiln tube 6 and are calcined. Through this design, the materials can be evenly transported from the feeding bin 1 to the kiln tube 6, thereby improving the calcination and purification efficiency of the materials.
