酸化による発熱の危険を伴う場合がある。 Coal is used in large quantities as a fuel and industrial raw material. Freight cars, ships, automobiles, etc. are used for transportation from coal mines, coal washing plants, or call centers to users. In this case, if the coal is lumpy and contains a few percent of moisture, problems such as scattering and oxidation will not occur, which is advantageous in terms of transportation. For example, in a burner combustion furnace, it is necessary to grind the powder so that it contains 70% or more of particles with a particle size of 74 μm or less, and to dry it to a moisture content of about 1%. It is extremely advantageous for users to deliver pulverized coal that has already been adjusted to a predetermined particle size and moisture content from a call center or coal supply base without having to perform operations such as crushing and drying on the user's side. be. Transporting such differentiated coal with a moisture content of approximately 1% and a particle size of approximately 70% below 74μm is carried out in a sealed container, tank truck, etc.
Since the bulk density is small at 0.4 to 0.5 g/ cm2 , the volume of a container that can store a certain amount of differential coal is relatively large.
Furthermore, since the specific surface area is large, there may be a risk of heat generation due to oxidation during transportation.

化を防止することができる。 When filling pulverized coal into a transport container, if the bulk density is increased, the volume of the container can be reduced, and a larger amount of pulverized coal can be transported in the same container. Furthermore, by filling the pulverized coal in a state with a low oxygen concentration, oxidation of the pulverized coal can be prevented during transportation or during long-term storage of the filled container.

The purpose of the present invention is to provide a filling device.

及び排気ポンプ５に接続されている。 As shown in FIG. 2, the compaction machine 3 has a vertical screw 15 disposed inside and below a conical hopper 21. The pulverized coal fed into the hopper 21 is sent out from the lower end opening of the hopper 21 at a controlled speed. At the exit of the tip of the screw, two rolls 19 are arranged which bite into each other and are rotated in opposite directions on their own. The roll 19 is surrounded by a casing 18, the lower part of which is provided with a discharge chute 20. A sealed box 17 is provided outside the lower part of the hopper 21 along the outer peripheral surface of the roll, and an exhaust pipe 2 is provided in this box and the upper part of the hopper.
2 and 23 are connected, and this exhaust pipe is connected to the fine powder collector 4.
and is connected to the exhaust pump 5.

浄化された後排気される。 The rotation of the vertical screw 15 sends the pulverized coal downward, but the two rolls 19 are rotated at a speed that limits the discharge of the pulverized coal by the screw 15, and as a result, the pulverized coal is deposited inside the screw or out of the screw. The pulverized coal is compacted at the lower end, and the gas and air inside the pulverized coal are expelled to the upper part of the hopper 21 or the upper part of the box 17, and transported through the exhaust pipes 22 and 23 by the action of the exhaust pump 5 to the fine powder collector 4. After being purified, it is exhausted.

ことができる。 The two rolls mentioned above are made so that the gap between them and the number of rotations of the rolls can be adjusted respectively.
Furthermore, the rotation speed of the screw 15 is also adjustable. This adjusts the degree of compaction of the pulverized coal. For example, if the roll gap is narrowed, the roll rotation speed is reduced, and the screw rotation speed is increased, the degree of consolidation increases. The bulk density of normal pulverized coal is 0.4 to 0.5 g/cm 3 , but it can be increased to 0.6 to 0.7 g/cm 3 using a compactor.

装置９が連結されている。 As shown in FIG. 1, pulverized coal that has been compacted by screws and rolls, degassed, and densified is fed from a lower chute 20 through a feed pipe 24 into a transport container 14. There is a supply port 1 in the transport container.
3 is provided, and a valve 12 and a mounting flange 11 are attached to this supply port, and this mounting flange 11 cooperates with a flange provided at the lower end of the feed pipe 24 to connect the feed pipe and the supply port 13. brings about connection with. A deaerator 10 is connected to the feed pipe 24 via a valve 8 on the downstream side of a valve 6 provided midway therein, and an inert gas injection device 9 is further connected to the feed pipe 24 via a valve 7 .
