Description

[Detailed description of the invention] This invention relates to a charging device in coke dry extinguishing equipment.When charging coke transported in packets into a furnace, the particle size distribution on the charging surface The aim is to improve the internal sediment distribution.

A conventional charging device will be explained with reference to FIG.

FIG. 1 shows a charging device having a conventional structure, and shows a state in which coke is charged using a coke packet when the lid is opened.

In the Gokoku, 1 is a cart that moves horizontally, and on the cart 1 are an upper hopper (receiving hopper) 2 and a lower hopper 3 for charging raw materials, and a receiving hopper 3 for when raw materials are not charged. Canopies 4 are arranged side by side and are used selectively as appropriate.

Reference numeral 5 denotes a hydraulic cylinder which moves the trolley 1 and operates a link mechanism 6 to raise or lower the canopy 4 as appropriate and to raise or lower the sealing mechanism 7 of the lower hopper 3.

(Details omitted) That is, in the state shown in Fig. 1, the canopy 4 is raised, the upper and lower hoppers 2 and 3 are installed on the charging port 9 of the furnace body 8 via the seal mechanism 7, and coke can be charged. It has become.

(10 is the coke bucket l-111 is the bottom lid of the coke packet 10) When charging is completed, the cylinder 5 and the link mechanism 6 lift up the sealing mechanism 7 of the upper and lower hoppers 2 and 3 (
(Details omitted) At the same time, move the trolley 1 to the left in the figure,
Once in position, the canopy 4 is lowered to cover the charging port 9.

When charging coke with a charging device configured as described above, no measures are taken to control particle size distribution, so
The charging surface distribution has an inverted V shape with fine grains in the center and coarse grains around the periphery, and as a result, the flow of cooling gas in the cooling chamber has a strong tendency to be a peripheral flow, and this is combined with the fact that the blasting device is located in the furnace core. , heat transfer between the cooling gas and the coke grain surface is extremely ineffective, resulting in an increase in the amount of cooling gas,
This results in an increase in chamber volume, which is a major problem in terms of capital investment.

Therefore, the present invention aims to eliminate the decline in cooling efficiency caused by the single pattern of V-type feeding, fine grains at the center and coarse grains at the periphery, which is seen in these conventional facilities. The purpose of the present invention is to provide a charging device that ensures a uniform (type) distribution.

Next, the present invention will be explained based on an embodiment shown in the drawings.

(See FIG. 2 and 3) 12 is a receiving hopper, 13 is a seal valve box having a seal valve 14 therein.

Further, the seal valve box 13 is provided with dust collection ducts I to 21 so that dust can be collected by a dust collector (not shown).

Reference numeral 15 denotes a lower hopper, the inner part of which is installed near the center of the coast via a material distribution bell 16 or a bell support 17.

The raw material distribution bell 16 is normally supported at four points as shown in the figure.

The raw material distribution bell 16 and the bell support 17 may be water-cooled in consideration of heat resistance.

For example, the shape of the raw material distribution bell 16 is as shown in FIGS. 4A and 4B.
In short, a bell is a general term for an axially symmetrical part-like object.

The furnace top charging device configured as described above is installed at the top of the furnace body 20 via the water seal device 18.

When the material distribution bell 16, bell support 17, etc. are damaged, they are moved to a predetermined location via wheels 19 and replaced.

When charging coke in a charging device having the above configuration, first, a coke packet 1 loaded with red hot coke is charged.
0 onto the receiving hopper 12, interlock it, and open the bottom lid 11.

Note that the seal valve 14 is opened before the bucket 10 is interlocked.

The red hot coke passes through the seal valve box 13 and hits a raw material distributing bell 16 fixed in the lower hopper 15 to be distributed.

When the sealing is completed, the seal valve 14 closes to completely seal the top of the furnace.

As described above, according to the present invention, despite the extremely simple structure, the desired V-shaped distribution, that is, coarse grains at the center and fine grains at the periphery, can be obtained, which is extremely effective in improving thermal efficiency, and has good sealing properties and is environmentally friendly. It is very desirable and has great practical value.
