Device and methodpreventing drying in pipe

Abstract

The invention relates to a device preventing drying in a pipe. The device is characterized in that the device comprises an automatic pouring system and a control valve; the automatic pouring system comprises a stirring device, a slurry discharging ball valve, a slurry pouring air operated reversing valve, a slurry pouring ball valve and an annular slurry pouring ring; the control valve comprises athrottle, a solenoid water valve, an air operated reversing valve, a reducing valve, an atomized lubricator, and a check valve; the stirring device is connected with the slurry discharging ball valveby a pipeline; the slurry discharging ball valve is connected with the slurry pouring ball valve and the annular slurry pouring ring by pipelines; and one way of the check valve is sequentially connected with the throttle and the solenoid water valve by the atomized lubricator, and the other way of the check valve is sequentially connected with the air operated reversing valve and the reducing valve. According to the scheme, stability and uniformity of long-term automatic pouring can be guaranteed, drying is prevented, and running stability of equipment is improved.

Description

technical field [0001] The invention relates to a device, in particular to a device and method for preventing dryness in a pipe, and belongs to the technical field of grouting structural components. Background technique [0002] After the existing coke oven is filled with coal, environmental protection requires that the furnace cover and the furnace seat must be sealed to prevent the toxic gas and dust inside from overflowing. The current technology is to pour grout, and the grout with a certain viscosity dries up in a high temperature environment to form a solid , adhered between the furnace cover and the furnace seat to play a sealing role. At present, there are two ways of manual grouting and automatic mechanical equipment. Automatic grouting in the environment of poisonous gas and dust in the coke oven is promoted and used. It flows into the furnace cover and furnace seat through the pipeline. The slurry is made of powdered grout and water and stirred into a liquid state...

Problems solved by technology

[0002] After the existing coke oven is filled with coal, environmental protection requires that the furnace cover and the furnace seat must be sealed to prevent the toxic gas and dust inside from overflowing. The current technology is to pour grout, and the grout with a certain viscosity dries up in a high temperature environment to form a solid , adhered between the furnace cover and the furnace seat to play a sealing role. At present, there are two ways of manual grouting and automatic mechanical equipment. Automatic grouting in the environment of poisonous gas and dust in the coke oven is promoted and used. It flows into the furnace cover and furnace seat through the pipeline. The slurry is made of powdered grout and water and stirred into a liquid state. After the water evaporates, it forms a block and adheres to the container. Therefore, the slurry adhered to the pipeline after a period of time after grouting The inside will become dry and gradually accumulate, the volume of the grouting pipe will become smaller, resulting in less grouting, and at the same time, it will dry up and block the holes on the grouting ring. At this time, the sealing quality of the furnace cover will be poor and there will be empty sections that cannot be grouted. Phenomenon
