Description

Unmanned automatic tower type filter press device

The present invention relates to a tower-type filter press device that pressurizes a slurry containing a large amount of water to form a cake, and more particularly, prevents meandering of the circulating filter cloth and prevents contamination of the filter cloth and rollers during operation, thereby increasing the operating efficiency. It relates to a good, unattended automatic tower type filter press apparatus.

Slurry generated at various industrial sites as well as sewage treatment plants contains a lot of moisture and contaminants, and therefore has a large environmental load. . Currently, various types of slurry cake forming equipment are used, and the equipment includes a filter press for compressing the slurry.

A filter press is a device for squeezing moisture by injecting a slurry between a plurality of filter plates equipped with filter cloth and then pressurizing the slurry. The squeezed water passes through the filter cloth and is drained to the outside, and the solid cake remaining in the filter plate is discharged separately.

There are various types of such filter presses, and among them, the tower filter press includes a plurality of horizontal filter plates that move up and down, a circulation type filter cloth passing between the filter plates, and a hydraulic actuator that raises and lowers the filter plate.

However, the conventional tower-type filter press has a disadvantage that the filter cloth is meandering finely from side to side during operation. That is, the filter cloth is pushed to the left or right as it circulates. It is natural that normal cake formation becomes difficult when the meandering of the filter cloth becomes severe. In addition, the conventional tower-type filter press has a limitation in that it cannot immediately remove the sludge adhering to the filter cloth or roller during operation. If the filter cloth is contaminated by the slurry, the pores of the filter cloth are clogged and water cannot drain properly from the slurry.

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

1 is a front view showing an external appearance of an unmanned automatic tower-type filter press apparatus 10 according to an embodiment of the present invention, and FIGS. 2 and 3 are views showing the internal structure of the unmanned automatic tower-type filter press apparatus 10 . In addition, FIGS. 4 and 5 are views for explaining the configuration and operation of the scraper shown in FIG. 2 .

As shown, the unmanned automatic tower filter press device 10 according to the present embodiment includes a sealed housing 11, a frame structure, a plate supporter 26, a plurality of filter plates 27, a lifting pressure plate 25, It includes an inlet cylinder 23 , a filter cloth 33 , a plate roller 31e , a scraper 40 , a filter cloth washing unit 50 , and a filter cloth running control unit 70 .

The hermetic housing 11 is a kind of container that accommodates the frame structure and the components supported by the frame structure to prevent leakage of odors generated during the operation of the filter press. A door 13 is installed on the side of the sealed housing 11 . As the door 13 is applied, maintenance related to the filter press can be performed.

In addition, the odor remover 15 is installed inside the sealed housing 11 . The installation location or capacity of the odor eliminator 15 may be changed as needed.

On the other hand, the frame structure includes a base frame 17 that is horizontally fixed to the ground, and a main frame 21 built on top of the base frame 17 . The frame structure is constructed by bolting and welding steel beams.

The plate supporter 26 is a structure fixed to the upper portion of the base frame 17 , and supports a plurality of filter plates 27 to be horizontally elevated. The filter plate 27 is supported by the plate supporter 26 in a downwardly compressed state.

The filter plate 27 is a hollow rectangular frame installed so as to be able to move up and down on the upper part of the plate supporter 26 , and is connected up and down by a link member 28 in a horizontal state. Up and down neighboring filter plates (27) are connected by a link member (28).

The filter plate 27 has two fixing pins 27a at both ends in the width direction so as to be connected through the link member 28 . The fixing pins 27a are spaced apart at regular intervals in the transport direction of the filter cloth 33 .

The link member 28 is a steel plate having a certain thickness, and as shown in FIG. 4 , has a substantially triangular shape and has a long hole 28a on one side. The link member 28 is located on the side of the filter plate 27 adjacent up and down, and is connected to the fixing pin 27a of the upper filter plate and the fixing pin 27a of the lower filter plate.

The link member 28 is rotatable around the fixing pin while being supported by the fixing pin 27a of the upper filter plate. In addition, the fixing pin (27a) of the lower filter plate is inserted into the long hole (28a), it is possible to move along the longitudinal direction of the long hole according to the close contact and spread of the filter plate (27).

As described above, the upper filter plate and the lower filter plate refer to upper and lower filter plates in two adjacent filter plates.

As shown in FIG. 3 , the filter plate 27 receives and compresses the slurry injected from the outside in a state in which it is pressed downward and in close contact with each other. Of course, as the slurry is compressed, the moisture contained in the slurry escapes. Since the dehydration method using the filter plate 27 is common, a description thereof will be omitted. In the filter plate (27) stack, the lowermost filter plate (27) is fixed to the plate supporter (26) via a link member (28).

The lifting pressure plate 25 is located on the upper part of the laminate of the filter plate 27 , and connected to the uppermost filter plate 27 through the link member 28 , and moves up and down by the hydraulic cylinder 23 . That is, it descends by the hydraulic cylinder 23 and presses down the filter plate 27 as shown in FIG. 3 or lifts the filter plate 27 to spread the filter plate at regular intervals.

On the other hand, the filter cloth 33 is a member that has a certain width and circulates along a predetermined path, and is interposed between the filter plates 27, passes moisture squeezed out of the slurry, and dehydrates the slurry residue, that is, The cake serves to export to the discharge conveyor 61 side.

The filter cloth 33 circulates at a constant speed by the driving wheel 29b while being supported by the plurality of guide rollers 31a. The driving wheel 29b rotates by receiving rotational force from the motor 29a and transfers the filter cloth 33 . In addition, a tension maintaining roller 31c is installed on the upper side of the motor 29a. The tension maintaining roller 31c presses the filter cloth by its own weight, so that the filter cloth 33 is in a tensioned state.

In addition, a plate roller 31e is installed at one end of each filter plate 27 . The plate roller 31e is positioned on the opposite side of the neighboring filter plates up and down, and supports the filter cloth 33 passing between the filter plates. The plate roller 31e is axially rotatably supported by the roller bracket 41 as shown in FIG. 4 .

The roller bracket 41 is a plate-shaped member fixed to one end of the filter plate 27 , and supports the two scrapers 40 . The scraper 40 serves to remove the contaminants adhering to the plate roller 31e and the filter cloth 33 . That is, the contaminants adhering to the outer peripheral surface of the plate roller 31e are peeled off, and the contaminants adhering to one surface of the filter cloth 33 are peeled off and removed. Contaminants include, for example, solid residues remaining after dewatering the slurry.

The scraper 40 is configured to include a parallel shaft 43a, a scraper rod 43h, a rotating arm 43c, and a spacing adjusting unit.

The parallel shaft 43a is a round bar-shaped member that is parallel to the plate roller 31e and both ends are supported so as to be axially rotatable by the roller bracket 41 . Both ends of the parallel shaft 43a are supported by the roller bracket 41 while passing through the passage (no reference numeral) formed inside the scraper rod 43h.

In addition, the scraper rod 43h is a bar extending in a straight line in the longitudinal direction and having a trapezoidal cross-sectional shape, is fixed to the parallel shaft 43a, and is rotatable in the direction of the arrow g or the opposite direction using the parallel shaft as the central axis of rotation. When the scraper rod 43h rotates in the direction of the arrow g, the corner portion of the scraper rod 43h comes into contact with the outer peripheral surface of the plate roller 31e and one side of the filter cloth 33 . The corners serve as blades to remove contaminants.

In addition, the rotary arm (43c) is coupled to the end of the parallel shaft (43a), as a part extending in a direction perpendicular to the longitudinal direction of the parallel shaft, and is pressed in the direction of the arrow k by the spacing adjusting unit. As the rotary arm 43c is pressed in the arrow k direction, the edge of the scraper rod 43h comes closer to the outer peripheral surface of the plate roller 31e or the filter cloth 33 .

The gap adjusting unit includes a nut block 43k, a male screw rod 43m, a pressure head 43n, and a locking nut 43p. The nut block 43k is a block-type member having a female screw hole and is welded and fixed to the roller bracket 41 . The male threaded rod 43m is a rod-shaped member having an external thread formed thereon and is screwed to the nut block 43k. It goes without saying that the male threaded rod (43m) reciprocates in the longitudinal direction as the shaft rotates.

The pressing head 43n is a part made of synthetic resin and is fixed to the tip of the male screw rod 43m and is in contact with the rotating arm 43c. In addition, the locking nut 43p is a nut that prevents the longitudinal movement of the male threaded rod 43m. After adjusting the position of the male screw rod 43m, the locking nut 43p is rotated and pressed against the nut block 43k to maintain the fixed state of the male screw rod 43m.

Among the scrapers 40 having the above structure, the scraper 40 in contact with the filter cloth 33 is contaminated with adhered to one side of the filter cloth 33 (the surface in contact with the slurry) when the filter cloth 33 circulates. The material is peeled off. In addition, the scraper 40 in contact with the outer circumferential surface of the plate roller 31e removes contaminants adhering to the outer circumferential surface of the plate roller 31e.

Meanwhile, as shown in FIG. 2 , the filter cloth washing unit 50 is positioned under the plate supporter 26 . The filter cloth washing unit 50 passes the filter cloth 33 inside and sprays washing water to the filter cloth 33 during transport to separate and remove contaminants from the filter cloth.

6 is a configuration diagram showing the filter cloth washing unit 50 separately.

As shown, the filter cloth washing unit 50 includes a washing chamber 51 , a drain pipe 52 , a guide pipe 53 , and a nozzle 53a.

The washing chamber 51 has a passage 51a as a case providing a washing space 51c. The filter cloth 33 enters the washing space 51c through one passage 51a, is washed, and then exits through the opposite passage 51a. The drain pipe 52 is a pipe provided under one side of the washing chamber 51, and discharges water and contaminants used for washing to the outside.

The guide pipe 53 is a pipe disposed on the opposite side with the filter cloth 33 interposed therebetween in the washing chamber 51 and has a plurality of nozzles 53a. Washing water pressed into the guide pipe 53 from the outside is ejected through the nozzle 53a. The washing water sprayed through the nozzle 53a hits the filter cloth 33 and removes contaminants attached to the filter cloth. The spray angle of the washing water may be 60 degrees to 70 degrees.

Referring back to FIG. 2 , it can be seen that the filter cloth running control unit 70 is installed on the side of the filter cloth washing unit 50 . The filter cloth running control unit 70 is installed on the transport path of the filter cloth, and serves to correct the meandering of the filter cloth when the circulating filter cloth is meandering.

Meandering means that the filter cloth moves left or right in the width direction while it is circulating. If the meandering continues, the filter cloth 33 will eventually deviate from the circulation path. In order to prevent this phenomenon, the filter cloth running control unit 70 is used. Also, correcting the meandering of the filter fabric means restoring the filter fabric that is deviated to the left or right to its original position. That is, the state is restored to the state before the meandering occurred.

7 and 8 are views showing the configuration and operation method of the filter cloth running control unit 70, FIG. 7 is a side view, and FIG. 8 is a plan view.

As shown, the filter cloth running control unit 70 includes a crossbar 17b, a roller support beam 75, a vertical support pin 71a, a variable roller 71, a meander detection unit 78, and a beam position adjustment unit. do.

The crossbar 17b is a section steel having a C-shaped cross section, and both ends are fixed to the base frame 17 . The crosspiece 17b has vertical support pins 71a that are orthogonal to the running direction of the filter cloth 33 and rotatably support the roller support beam 75 in the direction of the arrow s or the opposite direction.

The vertical support pin 71a is a member fixed to the longitudinal center portion of the crossbar 17b and extends vertically upward, and is fitted to the longitudinal center portion of the roller support beam 75 . The roller support beam 75 is rotatable while supported by the vertical support pin 71a.

The roller support beam 75 is horizontally disposed on the upper portion of the crossbar 17b, and both ends are supported so as to be adjustable in position while spanning the base frame 17 . To this end, fixed plates 75b are welded to the upper portions of both base frames 17, and sliding plates 75a are provided in lower portions of both ends of the roller support beam 75.

The fixing plate 75b is a plate-shaped member having a certain thickness and has a long hole 75c. The long hole 75c is a part of a circular arc with the vertical support pin 71a as the center of the circle. In addition, the sliding plate (75a) has a locking bolt (75f) protruding downward as a sliding plate in a state in which the upper surface of the fixed plate (75b) is slidable. The locking bolt (75f) is accommodated in the long hole (75c). In this way, by applying the long hole 75c and the locking bolt 75f, excessive rotation of the roller support beam 75 is prevented.

When an external force is applied to move one end of the roller support beam 75 in the direction of the arrow t or the opposite direction, sliding of the sliding plate 75a is possible within the range allowed by the long hole 75c. By moving one end of the roller support beam 75 in the direction of the arrow t, of course, the roller support beam 75 rotates around the vertical support pin 71a.

The variable roller 71 is axially rotatably supported on the roller support beam 75 through the roller bearing 72 . The filter cloth 33 rides over the variable roller 71 as shown in FIG. 7 .

The transfer direction of the filter cloth 33 and the axial direction of the variable roller 71 are always perpendicular to each other. Accordingly, for example, when the variable roller 71 is turned in the direction of the arrow s, the filter cloth 33 moves in the direction of the arrow w in FIG. 8 . By finely rotating the roller support beam 75, the position of the filter cloth in the width direction can be adjusted as much as possible.

The beam position adjusting unit is interlocked with a meandering detecting unit 78 to be described later, and when the filter cloth 33 is meandered, it rotates the roller support beam 75, that is, one end of the roller support beam 75 in the direction of the arrow t. or by moving it in the opposite direction to correct the position of the filter cloth 33 crossing the variable roller 71 .

The beam position adjusting unit includes a spring support body 76 , an air spring 77 , a connecting hose 77a , a distribution pump 77b , and a pump controller 77e .

The spring support body 76 is a member fixed to the opposite side with one end of the roller support beam 75 in the center. The spring support body 76 is bolted to the base frame 17 .

The air spring 77 is an air bag into which air is pressed, and is installed between the roller support beam 75 and the spring support body 76 on both sides. The air spring 77 can expand and contract according to the injected air pressure. For example, when the air spring 77 expands, the roller support beam 75 is pushed from the spring support body 76 as much as it expands. By controlling the amount of expansion and contraction of the air spring 77, it is possible to implement the rotational motion of the roller support beam.

The connecting hose (77a) has a distribution pump (77b) as a pipe connecting the air springs (77) on both sides. The distribution pump 77b is controlled by the pump controller 77e, and serves to move the air of one air spring to the other air spring. For example, in the drawing, a part of the air in the left air spring 77 is moved to the right air spring, or, conversely, a part of the air in the right air spring is moved to the left air spring. Accordingly, the volume of the left and right air springs is different, and the end of the roller support beam 75 can move in the arrow t direction or the opposite direction. That is, the left-right rotation of the variable roller 71 is possible.

On the other hand, the meander detection unit 78, detects the meandering of the filter cloth 33 during transport, and outputs a signal when the meandering is detected. The output signal is transmitted to the pump controller 77e to cause the pump controller 77e to operate the distribution pump 77b.

The meander detection unit 78 includes a contact plate 78k, an extension rod 78f, a sensor module 78c, and a fixing base 78a.

The fixing table 78a is installed on the base frame 17 and supports the sensor module 78c at a predetermined height. It goes without saying that the fixing table 78a is located on the side of the filter cloth 33 .

The contact plate 78k is formed by bending a metal plate of a certain thickness, and is in contact with the end of the filter cloth 33 in the width direction while being lowered by the action of gravity. One end of the filter cloth 33 in the circulating motion in the width direction passes by the contact plate 78k. When the filter cloth 33 moves straight forward normally, there is no change in the angle of the contact plate 78k with respect to the horizontal plane. However, when the filter cloth 33 meanders, the angle of the contact plate 78k changes.

The extension rod 78f extends in the longitudinal direction while being fixed to the contact plate 78k, and the extension end is connected to the sensing shaft 78d of the sensor module 78c. The change in the angle of the contact plate 78k is transmitted to the sensing shaft 78d.

The sensor module 78c calculates an angular change of the contact plate 78k based on the rotation angle of the sensing shaft 78d, and determines the degree of movement in the width direction of the filter cloth 33 through this. For example, it is to find out that the filter cloth has moved 1 mm to the left. The value calculated by the sensor module 78c is transmitted to the pump controller 77e. The pump controller 77e returns the filter cloth to its original position by finely adjusting the angle of the variable roller 71 through the distribution pump 77b based on the transmitted information.

As mentioned above, although the present invention has been described in detail through specific embodiments, the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical spirit of the present invention.
