Problems solved by technology
The third is that the thermal system is not properly controlled, resulting in local high temperature in the rotary kiln, and agglomeration and ring formation in the kiln
Seriously affect the stable production
Not only that, frequent temperature rise and fall will lead to a large amount of waste pellets, increased energy consumption, increased equipment damage, and adverse effects on labor intensity and safety of personnel

Embodiment Construction
[0015] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0016] like figure 1 As shown, the rotary kiln ring forming device of the present invention is characterized in that the fixed bracket 3 connected with the forklift teeth 6 inserted in the car, the telescopic rake rod 2 connected with the fixed bracket 3 and the telescopic rake rod 2 fixed The rake head 1 is connected, and the fixed bracket 3 is fixedly connected with the forklift teeth 6 inserted into the vehicle through bolts 5 and clamping plates 4 .
[0017] The telescopic rake rod of the present invention is composed of an inner rod 2-1 and an outer rod 2-2 sleeved on the inner rod 2-1, and the inner rod 2-1 and the outer rod 2-2 are provided with The fixed screw hole 2-4 is locked by the locking nut 2-3 after the screw hole 2-4 of the inner rod 2-1 and the outer rod 2-2 are docked.
[0018] In order to meet the needs of the actual ...

The invention relates to a block raking device for a formed ring of a rotary kiln, which is characterized by comprising a fixing support connected with forklift teeth of a forklift, a telescopic rake rod connected with the fixing support, and a rake head fixedly connected with the telescopic rake rod. The fixing support is connected with the forklift teeth of the forklift fixedly through bolts and clamp plates. The rake head is a flat rake head, a tooth rake head or a rake hook. The block raking device has the advantages that after the block raking device is adopted, high ambient temperature, high labor intensity, low working efficiency and personal safety problems of a post in the block raking process are completely avoided. Damages brought by the formed ring of the rotary kiln to stable and smooth production are prevented, times of temperature rising and dropping and generation of rejected pellets are reduced, the energy consumption is reduced, and the service life of equipment is prolonged. In addition, the device is flexible and convenient to use, low in cost, and easy to manufacture, and can be used repeatedly.
Description
technical field [0001] The invention belongs to the technical field of sintering equipment, and in particular relates to a rotary kiln ring forming device. Background technique [0002] In recent years, my country's pellet industry has developed rapidly, and there are more than 50 production lines of grate-rotary kiln pellets with a capacity of more than 2 million tons in the country. With the continuous improvement and maturity of production technology, the iron pellets produced have high grade iron, uniform particle size, good strength and less powder, which meet the requirements of blast furnace production. However, the ring formation of the rotary kiln seriously restricts the production and development of pellets. After research and analysis, there are three main reasons for ring formation in the rotary kiln: first, due to the poor strength of preheating balls and low bursting temperature of green balls, more powder enters the rotary kiln; The third is improper control...
