Description

Automatic shifting block device of rotary kiln

Technical Field

The utility model relates to a solid waste coprocessing technical field, concretely relates to automatic shifting block device of rotary kiln.

Background

The rotary cement kiln is used for cooperatively treating solid wastes, such as steel rolling oil sludge, oily sludge, oil-based drilling cuttings and the like, so that the harmless treatment of the wastes is realized, and the wastes are used as partial fuel to realize the resource utilization of the wastes. The pellets and the waste are dried and preheated by a grate and then are roasted at high temperature in a rotary kiln. In the high-temperature roasting process, materials form ring-forming objects on the inner wall of the rotary kiln, the ring-forming objects gradually form large ring-forming blocks, then collapse and fall off, and are conveyed to the kiln head along with the rotation of the rotary kiln and fall on a fixed screen of the kiln head.

Because the fixed screen and the longitudinal center of the rotary kiln are vertically arranged, and the included angle between the fixed screen and the horizontal plane is 13 degrees. Therefore, the large block of the ring can not be discharged from the side door after falling onto the fixed sieve, and can be moved out of the side door by external force. In addition, the distance between the side wall of the receiving hopper and the kiln hood at the side door is long, the receiving hopper is filled with heat-resistant concrete, a large number of pellets are stacked on a concrete platform in production, after the side door is opened, the stacked pellets need to be cleaned firstly, and then the large pellets can be pulled.

However, the rake head of the existing automatic block shifting device of the rotary kiln is fixed in structure and single in function. If the large rake head is used for cleaning the piled balls, the piled balls flow out from gaps between the rake claws, and therefore the problems of low cleaning efficiency and unclean cleaning are caused. If the large block is cleaned by the rake head for cleaning the piled balls, the rake claws cannot penetrate through the large block gaps, so that the problem of low cleaning efficiency is caused.

The sliding friction between the swing arm 41 and the telescopic arm 51 is converted into the rolling friction between the swing arm 41 and the telescopic arm idler assembly 500 and between the telescopic arm 51 and the swing arm idler assembly 400 by the swing arm idler assembly 400 and the telescopic arm idler assembly 500, thereby reducing the friction. This structure helps reduce friction.

The pivot cylinder 42 and the pivot cylinder 32 are of course connected to the hydraulic system 6. In addition, since the temperature of the working environment of the device is high, air ducts 8 are installed at both ends of the swing arm 41, and the air ducts 8 communicate with the cooling system 7.

The working principle of the utility model is as follows:

in use, the wheels 22 are driven to rotate by the travel drive motor 24 to effect movement of the device to facilitate adjustment of the device to a desired position. The rotary hydraulic cylinder 32 drives the rotary table 31 to rotate so as to enable the drag head 111 to swing left and right, and therefore the cleaning range is enlarged. The oscillating arm 41 is driven to oscillate up and down by the oscillating hydraulic cylinder 42 so as to insert the drag head assembly 1 into the material to be cleaned. The telescopic arm 51 is driven to reciprocate linearly by the telescopic drive motor 54 to pull the material back out of the rotary kiln.

Meanwhile, when the piled balls are cleaned, because the piled balls are small, if the rake head assembly 1 with large tooth pitch is used for cleaning, the cleaning efficiency is low. Thus, by activating the drive motor 16, thereby causing the first head 12 and the second head 13 to move apart, the pitch may be reduced while increasing the face of the drag head 111, thereby improving the efficiency of cleaning the stack balls.

When cleaning large blocks, if cleaning is performed with a rake head assembly 1 having a smaller pitch, the rake teeth 100 are difficult to insert into the large blocks, resulting in a lower cleaning efficiency. This is to increase the strength of the rake teeth 100 and thus the working efficiency by activating the driving motor 16 so that the first rake 12 and the second rake 13 are overlapped to increase the pitch.

In addition, sometimes the big block is too big, and if the rake teeth 100 are too short, the stress surface is too small to clean. In this manner, the length of the rake tines 100 may be varied by rotating the adjustment shaft 101 to facilitate cleaning.

In the specification of the present invention, a large number of specific details are explained. It is understood, however, that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.
