Description

Hopper drainage device {APPARATUS FOR DRAINING WATER USED IN HOPPER}

The present invention relates to a hopper (drip) discharge device, and more particularly to remove a large amount of fine coke generated on the return side of the drive pulley head portion during the coke (cokes) transport process of coal briquettes The present invention relates to a flushing device for discharging water in which water is sprayed down through a reservoir hopper.

In general, the coke transport of the coking facility is as shown in Figure 1, the coke (2) loaded on the belt conveyor (Belt Conveyer) 1 falls into the reservoir hopper (3), fine coke (4) of diameter 3mm or less A certain amount and a certain pressure to bury the return side and hit the return roller (5) and fall to the floor of the workplace to contaminate the surrounding environment or shorten the life of the drive belt and the return roller (5). The fine water coke 4 is removed by spraying the washing water 6.

However, the washing water 6 sprayed in this process falls along with the fine coke 4 and flows through the reservoir hopper 3 through the gap of the gate 7 and with the fine coke 4 to flow to the bottom. Not only does it pollute significantly, but it causes freezing during the winter season, and when it is severe, it is impossible to enter a transport vehicle, and there are problems such as a large number of personnel being mobilized to solve the problem.

Therefore, the present invention was devised to solve the coke transport problem of the conventional coking equipment such as the coke cleaning water of the reservoir hopper to fall to the bottom to contaminate the surrounding environment or freeze in winter fundamentally to smooth the phenomenon The purpose is to manage the equipment.

It is configured to include a down weight.

In addition, between the hopper gate and the movable drip plate includes a coke leak prevention plate fixed to the fixed support while having a rubber plate to prevent the discharge of the fine coke discharged from the hopper gate.

Hereinafter, the hopper according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 shows a perspective view of the coupling of the hopper gate provided in the bottom portion of the coke storage tank hopper of the hopper drain water discharge apparatus according to the present invention.

As shown in FIG. 2, the hopper gate 9 according to the present invention includes a washing down drain plate 10 and a washing down drain plate 11, and the washing down drain plate 10 includes coarse coke and washing down water. Filter holes (Hole) 12 for filtering the filter is formed in a predetermined shape, a predetermined interval, such a predetermined shaped hole is the coarse coke particles of the hopper outlet 14 as shown in the enlarged cross-sectional view (13) It is formed in a trapezoidal shape to prevent the phenomenon that it does not facilitate the drainage of the clean water by blocking the manure hole.

In addition, the locking jaw 15 is installed on both sides and the rear of the washing down drain plate 10 so as to coincide with the hopper outlet 14 to prevent the washing down from the hopper outlet 14 from flowing out of the front in the discharge direction. , The flushing drain plate 11 of the hopper gate 9 is manufactured to have the same width as the flushing drain screen 10 formed integrally with the hopper gate 9 so that a plurality of nuts are directly below the flushing drain screen 10. It is fastened to the bolt 16 and the 16, and the closing of the hopper gate (9) to function to discharge the flushing water flowing out from the flushing filter 10.

The hopper gate 9 is the fixing hole 20 of the upper end of the hopper gate 9 is inserted into the connecting projections 19 formed on each outer side of the fixing stand 18 located on both sides of the hopper outlet 14 The outer plate 22 having the bearing 21 is reinserted into the connecting protrusion 19 to be fixed to the nut 23 and the bolt 24 to enable smooth opening and closing of the hopper gate 9.

Figure 3 is a perspective view showing the arrangement of the device of the effluent drainage device of the hopper according to the present invention.

As shown in Fig. 3, a coke hopper outlet 14 is provided with a hopper gate 9 manufactured for the purpose of the present invention, and a plurality of rollers are provided with a movable drip 25 for guiding the flowing coke rinse water. (26) is installed on the top of the movable drip tray (26) is a separate structure so that the coke leak prevention plate 27 for filtering some fine coke flowing down with the washing water is strongly adhered to the top surface of the movable drip tray (25) It is firmly installed on the fixed support 28, the turnbuckle 30 for fastening one end of the tension adjustment rope 29 is installed on both sides of the upper center of the movable drip tray 25 to fasten the rope, and the hopper outlet Guide sheaves 31 of the wire rope 29 are installed on the left and right upper ends of the 14, and the ropes 29 passing through the wires 29 are fastened and fastened to the brackets 32 provided at the front ends of the gates 9.
