Continuous type coke furnace hot-state roof grouting system based on pressure balance of multiple group of delivery pipe

Abstract

The invention relates to a continuous type coke furnace hot-state roof grouting system based on the pressure balance of multiple groups of delivery pipes. The continuous type coke furnace hot-state roof grouting system comprises an air compressor, a first slurry mixer, a first slurry delivery pump, a second slurry mixer, a second slurry delivery pump and a slurry pressure uniform distributor, wherein the air compressor is connected with the air inlet valve of the first slurry mixer through an air pipe; the slurry outlet of the first slurry mixer is connected with the water inlet of the second slurry mixer through the first slurry delivery pump; the slurry outlet of the second slurry mixer is connected with the slurry pipe inlet of the slurry pressure uniform distributor through the second slurry delivery pump; the first slurry output pipe, second slurry output pipe, third slurry output pipe and fourth slurry output pipe of the slurry pressure uniform distributor are respectively connected with respective grouting pipes. The continuous type coke furnace hot-state roof grouting system disclosed by the invention has the advantages of simple structure, scientificity and reasonability in design, lower cost, high production efficiency and good slurry property without pollution and effectively reduces the manual labor intensity.

Description

technical field [0001] The invention belongs to the field of grouting systems, in particular to a continuous coke oven hot top grouting system based on the pressure balance of multiple sets of conveying pipes. Background technique [0002] The grouting of the coke oven hot roof and protective plate is an important work of the coke oven. The materials used for the masonry of the combustion chamber of a large modern coke oven are silica bricks, and the materials used in the roof area are clay bricks, insulation bricks, and coke oven cylinders. Bricks, etc., the coke oven is built from the cold state until the oven is heated to 600-800 ° C, and the coke oven expands outward along the direction of the combustion chamber. Since the expansion of silica bricks is greater than that of other refractory bricks, the temperature of the combustion chamber is also much higher than that of the furnace roof. The temperature in the area will inevitably produce multiple longitudinal cracks in...

AI Technical Summary

Problems solved by technology

The top of the coke oven is well sealed, the heat dissipation loss is small during the production process, and there are few volatile substances such as gas leakage, which can meet the requirements of energy conservation and environmental protection. The recovery system directly leaks to the combustion system, causing smoke from the chimney. The result is a waste of energy and environmental protection is not up to standard. The existing grouting system mostly uses multi-way pipes made of steel pipes, and the multi-way pipes are connected at right angles. Connection, the position of the main pipe and the branch pipe is different, the pressure of the branch pipe is different, the mud delivery volume is not equal, and because the pipeline is connected at a right angle, the mud transportation resistance is relatively large, and there is a dead angle, which is easy to block the pipeline. In addition, the existing The mixer in the technology will encounter the following problems when producing mud: 1, low efficiency, high labor intensity of workers, and low degree of mechanization; Under the action, fire mud dust swings out into the air, polluting the air; 3. The mud performance is poor, especially there may be large particles of impurities in the mud stuck in a certain part of the pouring gap, resulting in the situation that the mud cannot be poured below this position , resulting in poor sealing effect
