Description

By-product remover at the bottom of the carbonization chamber

The present invention relates to a by-product removal device of the carbonization chamber bottom that can automatically remove by-products remaining on the carbonization chamber floor during the coke operation by being mounted on the extruder.

In general, in order to produce coke, bituminous coal is put in a carbonization chamber with air blocking and hot distilled for a certain time (about 17 hours). The coke is dried and discharged to the outside by using an extruder, The process then proceeds.

The problem during the coke extruding process is that after the coke is discharged from the carbonization chamber, residual coke residue and other by-products remaining in the carbonization chamber bottom or inlet are locally heated at the bottom of the carbonization chamber to shorten its lifespan. Have In addition, these by-products include sticky liquid coal tar and the like, which prevents the carbonization chamber from being properly closed using a door installed at the entrance of the carbonization chamber, and especially during continuous charging and drying of bituminous coal. It causes a problem that a large amount of gas is leaked to the outside.

Conventionally, at the end of coke extrusion or at regular time, the operator directly removes the by-products of the carbonization chamber bottom and the inlet side, but this means that the temperature of the carbonization chamber bottom and the inlet side where the operator should be located for removal of the by-products is not cleaned. Since it is so hot that it is difficult to perform, it was undesirable in terms of cleaning efficiency and worker protection.

The present invention has been devised to solve such a conventional problem, and its purpose is to operate by mounting the extruder while extruding coke while automatically removing the by-products remaining in the carbonization chamber inlet and bottom. To provide a by-product removal device of.

Have Of course, the frames 13 and 15 are preferably located on one side of the charging vehicle by a separate mechanism (not shown), so that the frame 13 and 15 can move to the front side of the charging vehicle during cleaning (hereinafter, FIG. 1). The left side is called the front side in the state of).

On the front side of the frame 15, a heat sink 16 having a substantially plate shape is installed.

The tool support frame 27 is installed between the frames 13 and 15 so as to be moved in the vertical direction by a mechanism such as a cylinder, not shown, and a center portion of the tool support frame 27. The stopper 28 is integrally fixed to the proper position.

The first link bar 11A is rotatably installed on the upper portion of the frame 13 via the pin 12, and the length direction of the first link bar 11A is approximately equal to the front-rear direction of FIG. 1. same.

The upper end position of the rear end of the first link bar 11A is sensed by the limit switch 29 provided in the frame 13, and the front end of the first link bar 11A is the pin 30. The upper end of the third link bar (11C) is connected to the upper end of the second link bar (11B) via a spring member 22, the lower end side of the second link bar (11B) via the spring member 22. The third link bar 11C is in a state of receiving an elastic force toward the lower side by the spring member 22. Of course, the third link bar 11C is connected by a fitting structure so as not to be separated from the second link bar 11B.

The third link bar 11C is fitted to the hollow pipe-shaped guide bar 11D fixed to the frame 15 to slide upward and downward. A pin 14A is provided at the lower end of the third link bar 11C. One end of the cleaning tool support 17 is rotatably connected to the center, and the center portion of the cleaning tool support 17 is rotatably connected to the frame 15 via the pin 14B.

The scraper support 18 is mounted on the front end of the cleaning tool support 17 in the horizontal direction, that is, in the width direction of the carbonization chamber, and the scraper 19 is fixed to the scraper support 18. Of course, the length of the scraper 19 is set to be slightly smaller than the width of the carbonization chamber, the lower end portion is formed to protrude to the lower side than the cleaning tool support 17 and the scraper support 18 to scratch the by-product of the bottom To help.
