Description

Technical Field

[0001] The invention relates to the technical field of coal mills, and in particular to a device and method for online adding steel balls to an integrated processing machine. Background Art

[0002] The integrated treatment machine is the main equipment of the sludge co-combustion system of thermal power plants. Its working principle is to mix the steel balls and sludge by rolling and grinding through the rotation of the cylinder, and at the same time introduce high-temperature flue gas for direct drying. The sludge after preliminary drying and crushing is sent to the crushing and conveying section for further crushing and drying, and at the same time for conveying. During the entire crushing process, the steel balls rub against the sludge, and their own loss is inevitable. In order to ensure the long-term and reliable operation of the integrated treatment machine, the balls must be replenished regularly.

[0003] The existing method of replenishing balls is to manually add steel balls after the integrated processing machine is shut down, and the cylinder ball replenishment port must be turned to a vertical position before replenishing balls. The existing method of replenishing balls has the disadvantages of high labor intensity, long time for replenishing balls, and the equipment needs to be shut down for ventilation and cooling for a long time, resulting in long-term shutdown of the system. At the same time, due to the large weight of the steel balls themselves, personal injury accidents are very likely to occur during the process of transporting steel balls. When the equipment is shut down, it is repeatedly started to find the correct position, which increases the loss of equipment life and has a great impact on the economy and safety of the power plant.

[0004] After searching, the patent with application number CN202011507826.9 discloses a ball replenishing device for a steel ball coal mill, which belongs to the technical field of coal mills, and includes a ball replenishing sleeve, a ball replenishing channel is arranged inside the ball replenishing sleeve, a ball replenishing chamber is arranged on one side of the ball replenishing sleeve, and a cover plate is arranged on the upper end of the ball replenishing chamber. By setting a material guide component, it is not necessary to manually supply balls to the coal mill, which saves costs and improves the accuracy of the ball supply work. The material guide component can be used to evenly supply balls to the coal mill, thereby improving the working quality of the coal mill.

[0005] However, the above patent still has the problem that the steel balls will be worn out in the machine, and the worn steel balls cannot be recovered or reused, which will cause a waste of resources.
