Description

Filter press follicle vertically reciprocating device {APPARATUS FOR UP-DOWN RECIPROCAL OPERATION OF CLOTH FILTER IN FILTER PRESS}

The present invention relates to a device for dewatering sludge (SLUDGE) generated by coagulating sedimentation of wastewater from wet collection of gas (GAS) containing a large amount of dust (DUST) generated after a steelmaking converter is below a predetermined moisture content. In detail, after the filter of the dehydrator filters the sludge in the press-fitting state, the filter press is opened, and after the opening, the sludge cake produced between the foams falls down by its own load. The present invention relates to a filter press follicle vertically reciprocating device capable of cleaning the residual cake by removing the residual cake by UP-DOWN reciprocating movement of the follicle when the residual cake is attached to the follicle.

In the present invention, the action of the up and down of the follicles is moved by the motor of the follicle drive unit, and the inner and outer shafts are symmetrically operated up and down, so that the follicles move up and down, respectively, and the gap between the follicles moved downwards opens the remaining cake. It is supposed to be removed.

In the filter press equipment generally known as the equipment for the purpose of the present invention, a large amount of dust coming out after steelmaking is wet-collected, and the wastewater from wet is collected using chemicals (POLYMER) to aggregate contaminants in the water. THICKENER) is settled for a certain period of time, and the sludge generated in this way is transferred to the filter press through a feeding hole 19 by a pump while the filter plate 1 of the filter press equipment is press-fitted. It enters again and enters the CLOTH FILTER 2 through the feeding device 17 (refer FIG. 2A-2D). The sludge filtered and the filtered water inside the follicle 2 are discharged out through the drain hole 20 of the filter board 1. The remaining sludge is again dehydrated using hydraulic and pneumatic pressure and then turned into a cake that falls below a certain moisture content. When the filter board 1 is pulled and opened along the board moving rail 37 by the force of the cylinder, the cake is discharged downward by its own load. However, if the cake does not fall below a certain moisture content or for a long period of use of the follicles 2, a large amount of cake residue will remain attached to the follicles 2 without falling even if the sheet 1 is opened. The follicle 2 acts as an UP-DOWN in order to drop the remaining cake. As shown in FIG. 2D, when the follicle moving motor 3 is operated, the slide shaft 30 is rotated by the operation of the bevel gear 29. When the slide shaft 30 rotates as described above, the slide gear 24 and the bevel gear bitten by the slide gear bearing 31 on each filter plate 1 move to move the rotating shaft 32. Moving the rotating shaft 32 causes the sprocket to rotate to move the roller chain 26. Conventional follicle support rods 25 are connected to the roller chain 26 by tightening connecting bolts 21 so that the follicles 2 hanging on the follicle support rods 25 move up and down.

However, as described above, the follicle moving device is composed of a slide gear 24, a rotation shaft 32, a sprocket 27, and the like, each of which is supported by the upper support plate 34 for each filter board. If the filter press provided with the number of filter boards 1 is abnormal, the parts attached to one filter board 1 are abnormally affected by the other boards of the equipment, and at the same time, a large amount of the boards are damaged and the equipment cannot be operated. In addition, the connection of the follicles 2 is fastened to the follicle support rods 25, and the lower part of the filter board 1 is connected to the bottom by the tie-clads 13 so that many parts are dismantled when dismantling the lower tie clamps 13. There is a problem that must be dismantled in a narrow space between the board.

The present invention is to improve the conventional problems as described above, its purpose is to replace the follicle (2) of the follicle movement device to raise the follicle caught on the inner follicle support rod 14 to disassemble the tie clamp 13 and again In the opposite operation, the inner follicle support rod is lowered and the outer follicle support rod 15 is lifted up to disassemble the tie clamp 13 to facilitate the exchange of the follicles, and is engaged with the slide gear 24 located at the top of each leaflet 1. Eliminates the bevel gears and allows the follicles to move simultaneously in the opposite motion of the inner follicle (odd follicle) and the outer follicle (even follicle), simplifying the installation and reducing the occurrence of safety accidents caused by the bite of the gear. Due to the separation of the slide gear 24 of (1) and the bevel gear bite, the slide gear 24 and the bevel gear bite of the other filter part are separated and the other plate is broken. To provide a device that minimizes that.

(1) Provides a follicle vertically reciprocating movement device consisting of a connecting portion of the upper portion and a follicle hook portion that allows the follicle 2 to move on the upper shaft.

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

The cam limit switch 18 is connected backward to the half load side of the follicle moving motor 3, and the follicle moving gear 4 is attached to the load side. The inner movement gear 5 and the outer movement gear are bitten symmetrically vertically to the gear biting portion of the follicle movement gear 4 from side to side. The inner support 35 and the outer support 36 supporting the inner and outer moving gears 5 and 6 are fixed to the frame to support the gears to move up and down. The inner and outer shaft supports 7 and 8 are connected to the center portion of the inner and outer moving gears 5 and 6 horizontally using bolts 23, and the inner and outer shaft supports 7 and 8 are perpendicular to the inner and outer shaft supports 7 and 8, respectively. The outer shafts 9, 10 are connected by nuts 22. The inner and outer shafts 9 and 10 are connected with a moving pipe 11 which is fastened to each rod support chain 12 by the number of filter plates. The rod support chain 12 is caught by the moving pape 11, and a tie clamp 13 is assembled by connecting a tightening connecting bolt 21 to the end of the chain.

When the two outer follicle support rods 15 are connected to the tie clamp 13, two inner follicle support rods 14 are connected between the next medial plates, and are alternately connected between the respective medias 1 to move up and down. Inner and outer follicle support rods 14 and 15 are connected to one end of the follicle 2, one side of which is a long outer follicle support rod 15, and the other is connected to a short inner follicle support rod 14.

The center of the follicles 2 connected to the inner and outer follicle support rods 14 and 15 is caught by the return roller 16 attached to the lower part of the filter board 1 so that the follicles form a U shape.

Referring to the operation of the present invention made of such a configuration as follows.

When the follicle moving motor 3 rotates, the cam limit switch 18 operates at the same time to indicate when the motor stops. The follicle movement gear 4 is connected to the motor load side and the motor rotates at the same time so that the inner movement gear 5 and the outer movement gear 6 perform vertical movement but move oppositely. The inner movement gear 5 and the outer movement gear 6 are supported by the inner gear support 35 and the outer gear support 36, respectively, to move up and down symmetrically. Movement of the inner and outer gears 5 and 6 causes the inner and outer shaft supports 7 and 8 to move the inner and outer shafts 9 and 10 in the up and down direction. When the outer shaft 10 is moved upward, the outer follicle support rod 15 is hung on each moving pipe 11 so that the outer follicle support rod 15 is moved upward. At the same time, since the inner shaft 9 moves downward by the same position, the inner follicle support rod 14 caught on the inner shaft 9 moves downward. The follicle 2 is connected to the inner follicle support rod 14 that descends, so that the follicle 2 moves up and down through the return roller 16 and is connected to the inner follicle support rod 14 bitten by the tie clamp 13. There is a gap between (2), and the remaining cake falls. The follicle 2, which has been lowered by a certain distance, stops at the bottom by the predetermined lower limit operation of the cam limit switch 18 and starts to rise again. This time, the inner and outer shafts 9 and 10 move, so that the outer follicle support rod 15 goes down and the inner follicle support rod 14 goes up. In this case, the gap between the follicles 2 connected to the outer follicle support rod 15 is opened, and the remaining cakes CAKE are dropped by the return roller 16. In the case of replacing the follicles, the above operation may be repeated to dismantle the follicle support rods at the end of the follicle end up in the wide space above the filter press and dismantle the follicle support rods raised from below.

According to the device of the present invention as described above, because one of the follicles (2) surrounds one of the follicles (1), the damage of the follicles (2) is reduced, and the follicle life is long, and when replacing the follicles, the follicle is replaced by raising one side to the upper limit. 1) It is easy to work because the follicle can be exchanged in a large space of the upper part, and the frequent failure is prevented by eliminating the slide gear 24 and the bevel gears that are complicatedly assembled on the upper part of each conventional filter board 1 There is an effect that can eliminate the risk of safety accidents due to bevel gear installation. In addition, there is an effect that the operation according to the movement of the filter 2 up and down for eliminating the residual cake in the filter press can be performed simply and efficiently by simplifying the portion of the filter 1 and integrating the operation of the filter 2.
