Description

Anti-blocking cyclone for preheater Technical Field The utility model relates to the technical field of preheaters, in particular to an anti-blocking cyclone for a preheater. Background In the cement processing process, the use of the preheater is important for fully utilizing the heat in the kiln, reducing the sintering heat consumption of clinker and reducing the occupied area of sintering equipment, however, after long-term operation, the cone part of the cyclone in the preheater is easy to generate accumulation and skinning phenomena, so that the problem of blockage is caused, the kiln of the system is forced to be stopped for cleaning, and the production efficiency is seriously influenced, therefore, the anti-blocking cyclone for the preheater needs to be designed to solve the problem of blockage, so as to ensure the continuity and the stability of production, avoid the loss caused by shutdown maintenance and ensure the whole economic benefit. For example, chinese patent CN217125741U discloses a cyclone preheater with anti-blocking structure, which comprises a preheater main body, an air outlet port, an air inlet pipe, a guide cylinder, a mounting sleeve, a driving motor, a driving bevel gear, a fixing plate, a push rod and a baffle plate, wherein the push rod at each position is pushed by continuously rotating the rotating sleeve, so that the guide cylinder is repeatedly hit, and blocking at the guide cylinder is avoided. However, in the anti-blocking process of the cyclone preheater, since the ejector rod repeatedly strikes the guide cylinder to generate vibration to remove accumulated materials, the mode needs to accurately control the striking force, if the striking force is improper, the accumulated materials cannot be effectively removed, the equipment is possibly damaged, especially the long-term repeated mechanical impact can accelerate the abrasion of parts, the service life of the equipment is shortened, and the maintenance complexity and cost of the equipment are increased.
