Embodiment 1

[0018] Embodiment 1, a construction method for replacing the inner cylinder of the preheater cyclone of the cement clinker production line, is characterized in that it includes the following steps:

[0019] Firstly, limit the construction site site and working environment to the allowable scope of construction, reasonable layout and specification range, so that the signs are clear and complete, all kinds of signs are eye-catching, and the construction site is clean and civilized.

[0020] Then harden the roads at the construction site, and often sprinkle water on the construction roads in sunny days to prevent dust from flying and pollute the surrounding environment.

[0021] 1) According to the site conditions, use a crane or a hoist to reverse the inner tube hanging piece to the designated position on the preheater;

[0022] 2) Press down the heavy hammer flap valve of the feeding chute to be replaced and lock it with a 1T gourd to prevent the upper crust from collapsing and...

Abstract

The invention discloses an inner tube hanging sheet replacement construction method for a preheater cyclone of a cement clinker production line. The method is implemented by erecting of a scaffold, disassembling of hanging sheets, pouring construction, welding rod welding and the like. According to the construction method, a construction system is simple; the construction method is adopted instead of a conventional cyclone hanging sheet replacement construction method, so that construction safety is ensured, manpower is greatly saved, the construction period is shortened, and the cost is lowered; A / B series of hanging sheets of the cyclone are required to be simultaneously replaced, and by the novel method, two cyclones can be simultaneously operated by 12 operators, so that the construction time is saved by a half, and the stopping time of the production line is shortened.

Description

technical field [0001] The invention relates to the field of cement clinker production lines, in particular to a construction method for replacing the hanging pieces of the inner cylinder of the preheater cyclone of the cement clinker production line. Background technique [0002] At present, the cyclone of the precalcining kiln system plays the role of solid-gas separation and sufficient heat exchange. To realize this function, the key is the reasonable matching between the cyclone and the inner cylinder and the working condition of the inner cylinder. The main function of the inner cylinder is to enhance the swirl strength, enhance the heat exchange rate, and increase the decomposition rate. Due to different materials, different expansion coefficients, and various factors such as the use of temperature exceeding the limit, the hanging pieces of the inner cylinder generally have different degrees of deformation, damage, cracking, falling and collapsing, which will caus...
