Description

Apparatus for preventing an telescope clogging and method using the same}

The present invention relates to a telescope blockage preventing device and a method for preventing telescope blockage using the same. More particularly, the present invention relates to a telescope blockage preventing device and a method of preventing a telescope blockage using the same, by uniform charging, thereby improving coke quality and smoothing a gas passage.

In general, the coal charged in the carbonization chamber of the coke oven is coagulated by coagulation for a certain time.

The coke oven facility is composed of a rectangular box structure in which coal is charged and an combustion chamber that alternately burns fuel gas to supply heat required for coal drying. Between the oven and the combustion chamber, partition walls are formed as refractory bricks such as silica bricks, and conduct heat of combustion in the combustion chamber through the partition walls, thereby supplying heat to the coal in the oven and distilling them.

At the top of the coke oven is a charging vehicle running along the rail. The charging car forms a plurality of screw feeders that charge coal into the coke oven. And the charging vehicle is installed with a conveying device for charging the coal from the screw feeder into the coke oven.

Here, the pipe for introducing coal from the feeder to the coke oven is made of a telescope type double pipe structure. When charging the vehicle, the tube is contracted, and when coal is injected, the tube is extended and connected to the coke oven.

1 is a view showing that the charging vehicle is to put coal into the coke oven while traveling along the rail. 2 is a view illustrating a process in which coal loaded in a hopper of a charging vehicle passes through a screw peter and a telescope. FIG. 3 illustrates a process in which coal is poured into a screw feeder and the cover of the screw housing is opened and the spilled coal is poured into the charging hole when the coal path is blocked.

1 and 2, the charging car (2) in the coke oven (1) of the steelworks coke factory coal coal from the coal to the hopper (5) of the charging car (2) and then run along the rail to coke The screw feeder 6 is rotated in the carbonization chamber 4 to charge coal.

 Coal (3) charged in the carbonization chamber (4) is dried at a high temperature for a certain period of time to produce coke, which is pushed by an extruder and used as a heat source of the blast furnace.

In the carbonization chamber 4 which pushed out the coke, the charging vehicle 2 performs the repetitive operation of coaling and charging coal in the hopper 5.

On the other hand, when the charging car 2 charges the coal 3 into the carbonization chamber 4, many problems arise. When the coal (3) is charged, the long axis screw feeder (6) passes the coal (3) in the hopper (5) into the screw housing (14) and the telescope (7), so that tar and moisture-containing coal (3) and Due to the high temperature heat of the carbonization chamber 4, coal, carbon, and tar attached to the screw feeder 6 are attached to the telescope 7 so that the passage of the coal 3 is narrowed, so that the screw feeder 6 becomes coal ( 3) Push back and do not charge, so the worker should clean the window periodically. Further, when the screw feeder 6 is abnormal, the lower cover of the screw housing 14 is opened to pour the coal 3 in the hopper 5 to the bottom of the roadbed, and the coal 3 is shoveled with a large amount of attraction to the coke oven 1. It should be placed in the charging slot (8). As a result, workers may suffer from musculoskeletal diseases and burns, and work delays may occur.

In particular, the Palms facility, which improves the quality by using low-cost raw materials, has been operating. This facility produces coke by adding about 3% of tar to coal (3), so that tar can be attached to the telescope (7) as a charging device. have.

Because of this, the coal passage in the telescope (7) is often blocked, and the worker must go up to the height to remove the tar attached to the hard carbon into the window.

As a result, the coal 3 is not uniformly charged beyond the screw feeder 6, and the coal 3 is biased to either side, and the coke quality is lowered due to poor dryness, and in particular, the gas passage in the carbonization chamber 4 cannot be secured. Heavy gas leakage can cause air pollution, and in particular, production costs are high due to lower coal loading per minute.

Korean Patent Laid-Open Publication No. 2004-0110632, published December 31, 2004.

In one embodiment of the present invention, the coal is pushed into one side of the carbonization chamber so that the carbon dioxide is not dried up, the coke quality is deteriorated, and the gas passage is narrowed, so that the gas leaks into the carbonization chamber door and the like, thereby preventing the air pollution from clogging. And to provide a telescope clogging prevention method using the same.

According to an aspect of the present invention, the coal crushing unit for rotating and pulverizing coal by moving up and down; A telescope blockage preventing device including a driving unit for rotating the coal mill and a cylinder for moving the coal mill up and down may be provided.

In this case, the telescope clogging prevention device may further include a speed reducer for reducing the rotational speed of the drive unit.

On the other hand, the vertical movement of the coal mill may be guided by a guide rail coupled to the roller.

According to another aspect of the invention, (a) the telescope to move downward; And

(b) A method of preventing a telescope blockage may include providing a step of pulverizing the coal pushed by the screw feeder while the screw feeder and the coal crushing unit are rotated at the same time.

Telescope clogging prevention device and a telescope clogging prevention method using the same according to an embodiment of the present invention, the coal charging time is shortened, uniform charging is made to improve the coke quality and the gas passage is smooth and the gas leakage in the atmosphere Is reduced.
