Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a cement clinker rotary kiln. Background Art

[0002] A rotary kiln is a rotating calcining kiln, which is similar in appearance to a rotary bed. It is also called a rotary bed kiln. Rotary kilns are generally used to calcine cement clinker and are divided into two categories: dry process cement kilns and wet process cement kilns.

[0003] However, the existing technology still has some shortcomings. When the limited support is performed in the existing technology, the kiln body of the rotary kiln cannot be limited. Moreover, when the rotary kiln is working, the supporting support is prone to deflection, resulting in the kiln body being unable to rotate smoothly when calcining cement, thereby affecting the calcination of cement.

[0004] Therefore, we propose a cement clinker rotary kiln to solve this problem. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and to propose a cement clinker rotary kiln.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Preferably, the support mechanism includes a mounting frame fixedly connected to the bottom of the rotating cylinder; support wheels are rotatably mounted on both sides of the inner surface of the mounting frame; a mounting groove is provided on the upper surface of the mounting frame; and an auxiliary wheel is rotatably mounted on the inner surface of the mounting groove.

[0009] Preferably, the driving mechanism includes a base fixedly connected to the bottom of the rotating cylinder; a mounting plate is fixedly connected to the upper surface of the base; a support rod is rotatably mounted on the inner surface of the mounting plate; a driving gear is fixedly connected to the outer circular surface of the support rod; a speed reduction plate is fixedly connected to one end of the support rod; a motor is fixedly connected to the outer surface of one side of the mounting plate; and a brake is fixedly connected to the outer surface of the other side of the mounting plate.

[0010] Preferably, the support wheel cooperates with the support ring; the auxiliary wheel cooperates with the limiting ring.

[0011] Preferably, the output end of the motor is fixedly connected to one end of the support rod; the brake and the reduction plate cooperate with each other; and the driving gear and the outer gear ring are meshed with each other.

[0012] In the utility model, the cement clinker rotary kiln is provided with a limit ring, an outer gear ring, a mounting frame, a mounting groove, a support wheel, and an auxiliary wheel. The support ring and the support wheel cooperate with each other, the support wheel supports the support ring, thereby supporting the rotating cylinder, and the auxiliary wheel supports the limit ring, thereby stably supporting the rotating cylinder, thereby improving the stability of the rotating cylinder;

[0013] In the utility model, the cement clinker rotary kiln is provided with a base, a mounting plate, a support rod, a motor, a driving gear, a reduction disc, and a brake. When the rotary drum is rotated, the motor is started, the motor drives the support rod to rotate, the rotation of the support rod drives the driving gear to rotate, and the rotation of the driving gear drives the rotary drum to rotate through the outer gear ring; when the rotary drum is stopped, the brake is started, because the rotation of the support rod drives the reduction disc to rotate, the brake brakes the reduction disc, the deceleration of the reduction disc decelerates the outer gear ring through the driving gear, and the deceleration of the outer gear ring drives the rotary drum to decelerate, thereby quickly braking the rotary drum and improving efficiency;
