Description

Technical Field

[0001] The utility model relates to the field of steam calcining furnaces, in particular to a transmission device of a steam calcining furnace. Background Art

[0002] The driving pinion of the original transmission device of the steam calcining furnace is directly installed in a cantilever manner at one end of the transmission shaft. After the motor is speeded up by a speed reducer, it drives the elastic rubber block coupling to rotate, and then drives the large gear ring fixed on the outer surface of the furnace body of the calcining furnace through the transmission shaft and the pinion, so that the furnace body of the calcining furnace rotates accordingly. This transmission device matches the designed production capacity of 800 tons per day of the steam calcining furnace. With the continuous improvement and upgrading of the auxiliary system and the continuous improvement of the secondary dehydration process of adding a centrifuge before the heavy soda ash enters the furnace, the production capacity of the light ash calcining furnace has been greatly improved, and the deficiencies of the transmission mechanism have become prominent. In the original design, due to the acting force directly acting on the outer bearing at the output end of the speed reducer, the bearing is subjected to alternating impact forces, shortening the service life of the speed reducer, the elastic rubber block and the bearing at the output end of the speed reducer. At the same time, due to the long-term action of alternating stress on the pinion of the speed reducer, the output shaft generates elastic deformation, the steel foundation of the transmission device becomes loose, and the speed reducer vibrates, resulting in forced furnace shutdown for maintenance, shortening the normal operation cycle of the calcining furnace, and also greatly affecting the alignment accuracy of the motor and the speed reducer.

[0003] For example, the utility model with the publication (announcement) number: CN202732897U discloses a transmission device of a steam calcining furnace, which includes a transmission shaft, an elastic rubber block coupling, a pinion, a bearing seat at the output end of the speed reducer. The elastic rubber block coupling is connected to one end of the transmission shaft. The transmission shaft is also successively provided with a bearing seat at the output end of the speed reducer, a pinion and a support bearing seat. The support bearing seat and the bearing seat at the output end of the speed reducer are respectively fixedly connected to the steel foundation. Compared with the prior art, both sides of the transmission shaft with the pinion are fixedly connected to the steel foundation through the support bearing seat and the bearing seat at the output end of the speed reducer. The force received by the pinion is jointly borne by the two bearings on both sides, which can control the radial swing of the transmission shaft, effectively avoid the influence of alternating stress impact on the speed reducer and the bearing at the output end of the speed reducer, and the rotation process of the transmission device becomes relatively stable, extending the service life of the equipment.

[0004] The device of the above-mentioned utility model is provided with multiple bearing seats for bearing support, and after the bearing seats are fixedly connected to the steel structure and then reinforced by pouring cement, it is extremely inconvenient to disassemble and replace when the support seats are damaged and need to be maintained and repaired during use.

The reducer output end bearing and the support bearing are respectively fixedly installed with adapted bearing seats, and positioning mounting plates are fixedly connected to both sides of the bottom end of each bearing seat. Each bearing seat is fixedly installed on a base through an installation component.

[0007] Preferably: the other end of the coupling is fixedly installed with the output end of the reducer, and the small gear meshes with a large gear ring fixedly installed on the outer side of the boiler body.

[0008] Preferably: the base is provided with grooves adapted to the bottom ends of each bearing seat, and positioning grooves slidably adapted to the positioning mounting plates are respectively opened on both sides of the grooves of each base.

[0011] Preferably: a limiting screw rod is threadedly penetrated through the center position of the positioning mounting plate, and the bottom end of the limiting screw rod is threadedly fixed to the center position of the bottom end of the positioning groove.

[0012] Preferably: a connecting rotating shaft is rotatably connected to one side of each positioning mounting plate at the top end of the base, and a shielding block is fixedly connected to the top end of each connecting rotating shaft. The bottom end of the shielding block fits with the top end of each limiting screw rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] Embodiment 1

[0021] Please refer to Figures 1 - 3, The steam calciner drive device in the illustration includes a coupling 1, which is fixedly connected to one end of a transmission shaft.

It has been fully disclosed in the prior art and will not be elaborated here.

[0022] In this embodiment, the other end of the coupling 1 is fixedly installed with the output end of the reducer, and the small gear 3 meshes with the large gear ring 11 fixedly installed on the outer side of the boiler body.

The mounting component 7 includes mounting bottom sleeves 72 symmetrically installed at the bottom ends of each positioning groove 801. Each mounting bottom sleeve 72 is provided with a groove. A connecting rod 71 is slidably connected to the groove of each mounting bottom sleeve 72, and a spring is arranged in the groove of each mounting bottom sleeve 72. Both ends of each spring are fixedly connected to one end of the inner wall of the groove of the mounting bottom sleeve 72 and one end of the connecting rod 71 respectively. And the end of each connecting rod 71 away from the mounting bottom sleeve 72 abuts against the bottom end of the positioning mounting plate 6. A limiting screw 73 is threadedly penetrated through the center position of the positioning mounting plate 6, and the bottom end of the limiting screw 73 is threadedly fixed to the center position of the bottom end of the positioning groove 801.
