Problems solved by technology

With tamping heads, the tamping machines have to be arranged spaced apart from each other due to structural constraints and therefore cannot process the entire cross-section of the briquette

Embodiment Construction

[0031] exist figure 1 shows a charging unit 11 for a coke oven with a briquette 1 produced in a compaction mold 2 and a filling device 3 as well as a furnace group 4 .

[0032] The device 5 according to the invention has a structural unit 6 and a connection device 7 (for connection) to a holding device 8 arranged movably on a rail 9 , which device is mounted on a loading unit 11 . exist figure 1 The track 9 is only schematically shown in .

[0033] The structural unit 6 shown in detail in FIGS. 2 and 3 comprises a scraper 12 , an impact plate 13 and a device frame 14 for connecting these components.

[0034] The device frame 14 has a plate 15 , on which vertical telescopic guides 16 are mounted via two damping elements 40 , which in turn are connected to the impact plate 13 via damping elements 17 . The impact plate 13 is driven by two counter-running vibration (unbalance) motors 18 arranged on the impact plate.

[0035] Such as Figure 4 As shown, a height-adjustable lev...

Abstract

According to the invention, the loose coal is displaced from the peaks to the valleys of the waves on the narrow, long coal cake and is beaten down on the coal cake. The inventive device comprises at least one scraper (12) and at least one vertically movable impact plate (13) that are disposed one behind another and are fitted with a connection (7) to a holder. Furthermore, means are provided for generating a relative movement between the scraper (12) and the impact plate (13) and between the scraper (12) and a stamping form. The scraper (12) and the impact plate (13) are interconnected by means of a device frame (14) so as to form a structural unit (6) that is connected to the holder. Preferably, the structural unit (6) can be moved along the stamping form and is equipped with a drive unit. For this purpose, the holder encompasses a guide that extends along the stamping form as well as a carriage or a car which can be slid or moved on said guide and to which the unit (6) is connected with the aid of a boom.

Description

technical field [0001] The present invention relates to a method for removing loose coal on the corrugated surface of a narrow and long briquette solidified by tamping for coking by removing loose coal. The invention also relates to a device / apparatus for carrying out the method. Background technique [0002] To compress coal with a relatively high content of volatile components, molds are filled with granulated coal and solidified there by compaction. With the tamper heads, the compactors have to be arranged spaced apart from one another due to structural constraints and therefore cannot process the entire cross-section of the briquette. The result is therefore non-uniform solidification; thus forming areas with waves that have loosely placed coal on the crests and compacted coal in the troughs. [0003] Since the loose coal swirls in the coke oven due to the gas flow during the coking process and causes strong contamination there, it must be removed from the coal cake be...
