Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feeding equipment, in particular to a fuel alternative feeding device. Background Art
[0002] The dry process of clinker production is an important process in cement production. It produces cement by grinding, mixing and calcining raw materials. In this process, the selection and use of fuel has a significant impact on the efficiency and environmental performance of the production line. The traditional fuel is mainly coal, but with the improvement of environmental awareness and the increasing shortage of resources, the use of alternative fuels has received more and more attention.
[0003] At present, the alternative fuels of most cement plants are affected by the instability of the feeding device, and there are factors such as blockage and feed cutoff, which leads to a low utilization rate of alternative fuels. At the same time, the feed cutoff increases the air leakage at the discharge pipe, and the cold air leaks into the decomposition furnace to absorb heat, which in turn generates heat energy. The actual coal consumption savings are far less than expected.
[0004] For example, the publication number CN220981915U disclosed a new rotary feeding device for cement kiln alternative fuel on May 17, 2024. The transmission assembly can provide power for unloading. By providing a unloading assembly fixedly mounted on the transmission assembly inside the shell, the unloading assembly can unload the alternative fuel, and the unloading assembly can unload evenly to ensure the stability of the unloading process. In addition, when the unloading assembly is working, the unloading assembly is sealed with the shell to avoid gas exchange between the upper and lower ends of the shell, ensuring the sealing inside the shell. When the above-mentioned feeding device is working, the distribution fuel is prone to blockage, and the practicality is poor. Summary of the invention
[0005] The utility model aims to provide a fuel feeding device for alternative fuels that stably feeds fuel into a decomposition furnace. The utility model prevents fuel from being blocked in the distribution bin by dispersing components arranged in the feed bin, thereby ensuring that fuel stably enters the decomposition furnace for combustion, and has higher practicality.
[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model to solve its technical problem is: an alternative fuel feeding device, including a feed bin connected to a decomposition furnace, wherein a dispersion component for breaking up the fuel is arranged in the feed bin.
[0007] The feed bin is provided with a conical bin, and the dispersion component is arranged in the conical bin.

[0009] A fixing seat is provided on the outer wall of the conical bin, and the fixing seat is connected to the first motor. The power output shaft of the first motor is connected to the rotating shaft through a first coupling.
[0010] The rotating shaft is distributed in a conical shape in the conical bin.
[0011] A mounting seat is arranged on the conical bin, and a bearing connected with the rotating shaft is arranged inside the mounting seat.
[0012] The conical bin is connected to the decomposition furnace through a feeding bin, and a feeding assembly is arranged in the feeding bin.
[0013] The feeding assembly comprises a transverse axis arranged in the feeding bin, a spiral blade is arranged on the transverse axis, a second motor is arranged outside the feeding bin, and a power output shaft of the second motor is connected to the transverse axis.
[0014] A transverse seat is provided on the outer wall of the feeding bin, and the transverse seat is connected to the second motor, and the power output shaft of the second motor is connected to the transverse shaft through a second coupling.
[0015] The feed bin is provided with a feed port.
[0016] The beneficial effects of the utility model are:
[0017] The material moves in the feed bin, and the dispersion component works to realize the uniform movement of the fuel in the feed bin to the decomposition furnace, thereby preventing the material from being blocked before the fuel enters the decomposition furnace, thereby ensuring the stable and uniform feeding of the alternative fuel, and at the same time ensuring the safe, stable and efficient operation of the feeding device during the production process, greatly improving the use efficiency of the alternative fuel, and generating higher economic and safety benefits;
[0018] The first motor drives the breaking blocks on the rotating shaft to rotate in the conical bin, so that the fuel can fall evenly into the feed bin, and the second driving horizontal shaft drives the spiral blades to rotate in the feed bin, so that the fuel can stably enter the decomposition furnace, and the materials are continuously fed into the feed bin to fill the entire feed device, which greatly reduces the leakage of cold air into the system and further plays the effect of saving energy. The first motor and the second motor are controlled to rotate forward and reverse, and clear the blockage when it occurs. BRIEF DESCRIPTION OF THE DRAWINGS
