    1536069 Charging a coke oven HUTNI PROJEKT PRAHA 25 Feb 1977 [26 March 1976] 8126/77 Heading F4B A method of supplying a preheated coal charge to a coking chamber 6, Fig. 2, of a coke oven comprises the steps of pneumatically transporting the coal charge from a metering container 81 through a conduit 42 by means of a pressurized neutral carrier medium (such as nitrogen), separating the carrier medium from the coal charge in a degassing separator 46, dividing the separated coal charge into two streams, and distributing the coal charge by gravity through shoots 49, 50 to the coking chamber. The container 81 has closure valves 71, 73 and is supplied with the pressurized carrier gas by a device 75, Fig. 1. By appropriate positioning of valve means 44, Fig. 1, container 81 can supply any of chambers 6-10. Similarly, container 80 (which has closure valves 70, 72 and a carrier medium supply 74) can supply any of chambers 1-5 or 11-15 via conduit 41, degassing separator 45 and shoots 47, 48. The valve means 44 direct the pneumatically transported coal to a required coking chamber via a bent conduit 61, Fig. 3. The coal follows the outer part of the bend and the carrier medium follows the inside of the bend from where it is removed through a pipe 33 and suction conduit 43, Fig. 1.

    The invention relates to a coke-chemical product, namely, devices for pneumatic loading of preheated coal into a coke oven. A device for pneumatically charging preheated coal into a coke oven is known, including a dosirukiy bunker, a pneumatic conduit located above the coke oven battery, gas and coal separation chambers located above the coke ovens, connected to the furnace charging ports and a pipe for removal. gas C The disadvantage of the known device lies in its low operational reliability due to this. iTO it contains a large number of gas separation chambers. The purpose of the invention is to increase operational reliability. The goal is achieved by the fact that the device for pneumatic loading of preheated coal into a coke oven, including a metering bin, a pneumatic conduit located above the coke oven battery, gas and coal separation chambers located above the coke ovens, connected to the furnace charging ports and having . coal supply, connected to pneumatic, wire, and gas outlet pipe; separation chamber connected to charging hatches by means of barriers. And it is equipped with a partition, which is located between the grooves, the coal pipe is located inside the chamber and has wedge-shaped (Holes Radir to the lower part of the nozzle and opposite the nozzle for exhaust gas, the cutting pipe for coal supply and the adjacent wall of the separation chamber have an arcuate shape. Fig. 1 shows the diagram of the proposed installation; Without A-A in Fig. 1; in Fig. 3 - a dividing chamber, a section J in Fig. 4 - a section B-B in Fig. 3} in Fig. 5 - view B in Fig. 3; in Fig. B - section YYY in Fig. 3. A device for pneumatic loading of preheated coal into a coke oven includes a metering hopper 1, a pneumatic line 2 located above the coke oven battery 3 4. A chamber 5 for separating gas and coal, which are connected to the charging, is located above the coke ovens 4 Lkskami 6 coke ovens 4. Chamber 5 is connected to the pneumatic line 2 and has a nozzle 7 for the removal of gas. The chamber 5 is connected to the loading hatches via the channels 8 and is provided with a partition 9 placed between the channels 8. The coal supply pipe 10 is located inside the chamber 5 and has a wedge-shaped opening 11 extending to the bottom of the pipe 10 and opposite the pipe 7 for venting gas. The coal feed pipe 10 and the adjoining wall of the separation chamber 5 are arcuate. The device works as follows. The dosing hopper 1 is installed under pressure. Neutral environment, preparing the heated coal charge to the pneumatic loading. After opening the valve 12, the coal mine is transported via the pneumatic line 2 to the chamber 5 connected to the charging hatches 6 of the coke oven 4. In the chamber 5, the carrier medium is separated by centrifugal force and discharged through the nozzle 7 to the pipeline 13 for venting gas. Separated from the gas heated by the force of gravity to the chutes 8 and is divided into two streams through the partition 9. In the chutes 8 there is an additional separation of gas and its removal through the pipe 7. The mixture slides through the chutes 8 and through the loading hatches b enters coke oven 4. After the bunker 1 is completely emptied and the coke oven is filled, the medium supply is shut off and the valve 12 is closed. The invention not only allows for the separation of gas from coal, but also ensures that the charge is distributed to the feed Yux1M, which increases the reliability of the installation.
