Description

Anti-fog filter cloth removable filter press {MOVABLE FILTER CLOTH TYPE FILTER PRESS FOR PREVENTING JAM}

The present invention relates to a filter cloth movable filter press provided with a filter cloth between the filter plates to be able to lift and lower. More specifically, the suspension contraction that supports the filter cloth in the upper part of the filter plate extends in the front-rear direction from the upper left and right sides of the filter plate. It relates to an anti-foam filter cloth mobile filter press connected with a bevel gear and a universal joint or a flexible shaft fastened to a hexagonal bar.

In general, sewage that is disposed of in homes or factories is treated after being sent to a sewage treatment plant, and sludge generated in this treatment is processed through a reduction process such as concentration and dehydration. The dehydrator, which is one of the devices used in the sludge reduction process, separates the filtrate from the sludge, and is classified into a belt press, a filter press, a screw press, a centrifugal dehydrator, an electropenetrating dehydrator, and the like according to an operating principle.

The filter press is a device for injecting sludge into the chamber provided between the filter plates in close contact with each other to separate the filtrate from the sludge, and then removing the sludge cake (dehydrated sludge) from the chamber. Such filter presses are classified into filter cloth mobile filter presses and filter cloth fixed filter presses, depending on whether the filter cloth provided to surround the chambers between the filter plates is provided to be lifted or fixed to the filter plate.

During dewatering in the filter cloth mobile filter press, the filtrate separated from the sludge passes through the filter cloth surrounding the filter chamber and then is discharged to the outside of the filter plate via between the surface protrusions of the filter plate. And when the dehydration is finished, the sludge cake is first separated from the filter cloth by falling free from the open chamber by the separation of the filter plates. After the filter plates are spaced apart, the two sheets of filter cloth, which form the filtrate, are separated from each other by going down, where the sludge cake is separated secondarily from the filter cloth. When the separation of the sludge cake is completed, the filter cloth is raised again, and then the filter plates are in close contact. Then, two sheets of filter cloth positioned between the filter plates form a chamber again, and the sludge to be dehydrated is pressed into the chamber.

Thus, in the filter cloth mobile filter press, since the filter cloth must move up and down, the filter cloth lifting means is provided. The conventional filter cloth lifting means includes a pair of hexagonal bars and a plurality of filter cloth suspension shafts. The pair of hexagonal bars are spaced apart from each other in the width direction (left and right directions) of the filter plate, and are provided to be rotatable about a rotation axis extending along the line direction (front and rear direction) of the filter plate, and are positioned above the filter plates. The plurality of filter cloth suspension shafts extend in the left and right directions, are spaced apart from each other in the front and rear directions, and are rotatable based on a rotation axis extending in the left and right directions. These filter cloth suspension shafts are respectively coupled to the hexagonal bar through the bevel gear. Moreover, although the sprocket is provided in the both ends of the filter cloth suspension shaft, the chain which suspended the filter cloth hangs on this sprocket.

When the hexagonal rods rotate in the forward direction, the filter cloth suspension shafts also rotate in the forward direction, and the filter cloth is raised. On the other hand, when the hexagon rods rotate in the reverse direction, the filter cloth suspension shafts also rotate in the reverse direction, and the filter cloth is lowered.

A filter cloth mobile filter press having a filter cloth lifting means as described above is disclosed in Korean Patent No. 10-0541328 (filter press) and Korean Patent No. 10-1308939 (filter mobile filter press).

On the other hand, as disclosed in Korean Patent No. 10-1545547 (filter mobile filter press) and Korean Patent No. 10-1572055 (filter mobile filter press), there is also known a filter cloth mobile filter press of the form without a hexagon bar.

In the filter cloth movable filter press provided with a hexagon bar, a hexagon bar penetrates the ring gear of the bevel gear, and one end of the filter cloth suspension shaft is fastened to the pinion gear of the bevel gear. Therefore, when the filter plates are opened and closed, the ring gear is linearly moved along the hexagonal bar.

However, since the hydraulic cylinder is pushed or pulled at the center of the pressure plate located in front of the frontmost filter plate, the opening and closing plates of the filter plates, there is no difference in the linear movement distance of the left and right ends of the filter plates and the upper and lower straight movement distances. If the difference is large, the linear motion of the filter plates cannot be smoothly performed, and thus the filter press is eventually broken.

Therefore, the present invention is to provide a technology that can prevent the destruction of the filter press by making the linear movement of the filter plates smoothly even if there is a difference in the linear movement distance of the left and right ends and the upper and lower ends of the filter plates.

<General Filter cloth  Removable Filter Press>

For a clear and easy understanding of the present invention, a general filter cloth mobile filter press 10 will first be described with reference to FIGS. 1 and 2.

Generally, the filter cloth movable filter press 10 includes a frame, a pressure plate 20, filter plates 30, and a hydraulic cylinder 40 as shown in FIG. 1.

The frame includes a front plate 12 and a rear plate 14 which are spaced apart in the front-rear direction. The frame also includes a pair of supports 16 which are spaced apart in the left and right directions, both ends of which are fixed to the front plate 12 and the rear plate 14.

The pressing plate 20 is located between the front plate 12 and the rear plate 14, as shown in Figure 1, and is coupled to the support 16 so as to slide along the front and rear direction. In addition, the pressure plate 20 is connected to the foremost filter tube 30 through the chain 22.

The filter plates 30 are located between the pressure plate 20 and the back plate 14 as shown in FIG. 1, and are coupled to the support 16 so as to slide along the front and rear directions. In addition, neighboring filter plates 30 are connected by a chain 22.

The hydraulic cylinder 40 is for moving the pressure plate 20 in the front-rear direction, and is mounted to the front plate 12 as shown in FIG. 1. The rod 42 of the hydraulic cylinder 40 is fixed to the pressure plate 20.

When the hydraulic cylinder 40 is operated in the above-described filter cloth mobile filter press 10 and the rod 42 is pulled out, the pressure plate 20 is pushed by the rod 42 and moved toward the rear plate 14. At this time, the filter plates 30 move toward the rear plate 14 while being pushed by the pressure plate 20, and reach a closed state (closed state) in close contact with each other as shown in FIG. On the other hand, when the hydraulic cylinder 40 is operated in the closed state and the rod 42 is retracted, the pressure plate 20 is led by the rod 42 to move toward the front plate 12. In this case, the filter plates 30 connected to the chain 22 are moved toward the front plate 12 by the pressure plate 20, and reach an open state (open state), which is separated from each other as shown in FIG.

When the sludge is pressed into the filter plates 30 while the filter plates 30 are closed, the sludge is dewatered. In addition, the filter cloth 50 is required to dewater the sludge, and the filter press 10 includes a plurality of filter cloths 50.

The filter cloth 50 is provided in a form in which a pair of cloth overlap each other as shown in FIG. An upper rod 56 is provided at an upper end of the filter cloth 50, a lower first rod 58a is provided at a lower end of one pair of fabrics, and a lower lower rod 58b is provided at a lower end of the remaining fabrics. It is prepared.

In addition, a sludge passing plate 52 is provided in the upper center of the filter cloth 50. The sludge passage plate 52 has a sludge passage hole 52a through which the sludge press-fitted passes through the sludge passage hole 52a. In addition, the sludge passage plate 52 also includes a sludge supply passage 52b located at a part of the inner circumferential surface of the sludge passage hole 52a, and due to the sludge supply passage 52b, the sludge passes through the sludge passage hole 52a. Can be supplied between a pair of guns.

The filter cloth 50 thus formed is located between the filter plates 30 as shown in FIG. When the filter plates 30 are in the closed state, the sludge passage hole 52a of the sludge passage plate 52 communicates with the sludge passage hole 34 of the filter plate 30, and a part of the portion of the filter cloth 50 ( b) (hereinafter, referred to as a 'non-contamination site'), a pair of fabrics are pressed by the filter plate 30 to abut, and an upper portion (a) of the site (b) (hereinafter referred to as a 'contamination site') In Esau 54, which is a pair of interspaces, is provided.

When the sludge is press-fitted in the closed state, the sludge passes through the sludge passage hole 52a of the sludge passage plate 52, the sludge passage hole 34 of the filter plate 30, and the sludge supply passage 52b of the sludge passage plate 52. It is supplied to the chamber 54 of all the filter cloth 50 while passing through. The sludge is dewatered by press input in the filter chamber 54. At this time, the filtrate passes through the filter cloth 50 and the sludge cake remains in the filter chamber 54. On the other hand, the filtrate passing through the filter cloth 50 moves downward along the gap between the projections (not shown) provided on the retraction surface 32 of the filter plate 30, and then a hole (not shown) at the bottom of the filter plate 30 Is discharged to the outside of the filter plate (30).

When this condition continues for a predetermined time and the sludge dewatering is completed, the filter plates 30 are opened, in which the sludge cake falls free from the chamber 54. Since the filter cloth 50 is lowered, this is to remove the sludge cake remaining in the contaminated portion (a) of the filter cloth (50). The filter cloth 50 lowered to the lower limit rises back to the original position. On the other hand, at the time of lifting the filter cloth 50, the filter cloth 50 is washed by the washing water injected from the washing water injection pipe (92).

The filter cloth 50 is connected to the lifting chain 78 as shown in FIG. 2 for the lifting movement as described above. Specifically, the upper rod 56 of the filter cloth 50 is coupled to the upper end of the elevating chain 78, and the first and second lower rods 58a, 58b of the filter cloth 50 are the elevating chain 78 Is coupled to the bottom of the. When the coupling relationship between the filter cloth 50 and the elevating chain 78 is as described above, all the filter cloth 50 can be raised and lowered at the same time.

The lifting chain 78 is suspended at both ends of the suspension shaft 76. Therefore, when the suspension shaft 76 rotates in the forward direction, the filter cloth 50 descends, and when rotated in the reverse direction, the filter cloth 50 rises.

One end of the suspension shaft 76 is coupled to the hexagonal bar 74 through the bevel gear 77, as shown in Figure 1, the opposite end of the bracket 75 and the bearing fixed to the top of the filter plate 30 Combining through. The bevel gear 77 moves along the hexagonal bar 74 when the filter plates 30 move forward and backward, and transmits the rotational force of the hexagonal bar 74 to the suspension shaft 76. Meanwhile, the front end of the hexagonal bar 74 is connected to the drive shaft 72 through another bevel gear 72a as shown in FIG. 1, and the drive shaft 72 is mounted to the front plate 12. It is connected to the motor 70. The rear end of the hexagonal bar 74 is rotatably coupled to the upper end of the rear plate (14).

When the motor 70 operates in the filter cloth moving chamber filter press 10, the filter cloth 50 is raised or lowered while the driving shaft 72, the hexagon bar 74, and the suspension shaft 76 rotate.

<Anti-filter cloth removable filter press>

Hereinafter, the features of the anti-foam filter cloth removable filter press 100 according to the present invention compared to the above-described general filter cloth mobile filter press 10 will be described with reference to FIGS. 3 to 6. Reference numerals are used as they are.

The anti-foam filter cloth mobile filter press 100 according to the first embodiment of the present invention includes a filter cloth suspension shaft 76, a universal joint 150, a bevel gear 77, and the like as shown in FIGS. 3 and 4. And a bevel gear housing 130, a rail 120, a housing stopper 160, and a traction chain 110.

The filter cloth suspension shaft 76 is supported by bearings on left and right brackets 73 and 75 fixed to the left and right ends of upper surfaces of each of the filter plates 30 arranged in the front-rear direction. Accordingly, the filter cloth suspension shaft 76 may rotate about an axis extending along the left and right directions while being supported by the left and right brackets 73 and 75. At the left and right ends of the filter cloth suspension shaft 76, a sprocket 76a is provided to hang the lifting chain 78 suspended from the filter cloth 50.

The universal joint 150, as is well known, is a joint that includes two portions 152 and 154 that allow a change in angle with respect to each other while still allowing the rotational force of any one portion to be transferred to the other portion as it is. In the present invention, the first portion 152, which is one of the two portions 152 and 154 of the universal joint 150, is fixed to the left and right ends of the filter cloth suspension shaft 76, and alternately fixed left and right while going in the front-rear direction. do. Thus, if the first portion 152 of the universal joint 150 is fixed to the left end of the filter cloth suspension shaft 76 in one of the filter cloth suspension shafts 76 adjacent to each other, the other filter cloth suspension shaft 76 It is fixed at the right end.

The bevel gear 77 has a structure in which the ring gear 77a and the pinion gear 77b are vertically engaged with each other. The ring gear 77a is coupled to the hexagon bar 74 so as to penetrate the hexagon bar 74. Therefore, the ring gear 77a may rotate together with the hexagonal bar 74 and move forward and backward along the hexagonal bar 74.

The pinion gear 77b is vertically engaged with the ring gear 77a. Therefore, when the ring gear 77a rotates about the axis extending in the front-rear direction due to the rotation of the hexagonal bar 74, the pinion gear 77b rotates about the axis extending in the left-right direction. In addition, the rotation shaft 77b-1 of the pinion gear 77b is fixed to a portion of the two portions 152 and 154 of the universal joint 150 that is not coupled to the filter cloth suspension shaft 76, that is, the second portion 154. do. Therefore, when the pinion gear 77b rotates, both the universal joint 150 and the filter cloth suspension shaft 76 rotate.

The bevel gear housing 130 surrounds a rotating shaft (not shown) of the ring gear 77a so as to move along the hexagonal bar 74 together with the ring gear 77a. In addition, a bearing (not shown) is provided between the bevel gear housing 130 and the rotating shaft of the ring gear 77a so that the bevel gear housing 130 does not rotate even if the ring gear 77a rotates together with the hexagonal bar 74. do.

In addition, the bevel gear housing 130 also encloses the rotation shaft 77b-1 of the pinion gear 77b, wherein a bearing (not shown) is also provided between the bevel gear housing 130 and the rotation shaft 77b-1 of the pinion gear 77b. City) is prepared. Therefore, even if the pinion gear 77b rotates, the bevel gear housing 130 does not rotate. On the other hand, the end of the pinion gear rotation shaft (77b-1) slightly protrudes out of the bevel gear housing 130 to be fixed to the second portion 154 of the universal joint 150.

In the related art, the bevel gear housing 130 is fixed to the left and right brackets 73 and 75 of the upper surfaces of the filter plates 30. However, in the first embodiment of the present invention, the connection between the bevel gear housing 130 and the left and right brackets 73 and 75 is broken, and the pinion gear 77b and the filter cloth suspension shaft 76 are connected by the universal joint 150. . Therefore, in the first embodiment of the present invention, the conventional problem that the ring gear 77a is fitted to the hexagonal bar 74 does not occur at all.

When the filter plates 30 move from the open state to the closed state, the filter plates 30 are sequentially abutted while the front filter plate 30 moves backwards, and in this process, the left end of the filter plates 30 is right. Distortions, ie left and right, are caused by more advanced or less advanced stages. This left and right twist occurs even when the filter plates 30 move from the closed state to the open state.

In addition, when the filter plate 30 moves in the front-rear direction, not only the left and right sides of the filter plate 30 but also the inclination of the upper and lower sides are generated. That is, since the filter plate 30 has a structure in which the center of gravity thereof is located downward, when the filter plates 30 in the open state are pushed backwards in order, the upper ends of the filter plates 30 are more backward than the lower end. Tilt, ie, tilting up and down, occurs.

However, when the bearing housing 130 is fixed to the left and right brackets 73 and 75 of the filter plate 30 as in the related art, left and right twists and / or vertical tilts of the filter plates 30 occur in various filter plates 30. If the cumulative ring gear (77a) is stuck to the hexagonal bar (74) and can not be reversed, the hydraulic cylinder 40 continues to press the filter plates 30 to the rear, so that the housing ( 130 breakage, or breakdown of the brackets 73 and 75, or breakage of the suspension shaft 76 will occur.

However, in the first embodiment of the present invention, the connection between the bearing housing 130 and the left and right brackets 73 and 75 is disconnected, and only the left end or the right end of the filter cloth suspension shaft 76 is the pinion gear 77b of the bevel gear 77. ) And the universal joint 150, the second part 154 of the universal joint 150 maintains its posture only when the left and right and / or the vertical tilt of the filter plate 30 occurs. Only the angle of the first portion 152 with respect to the second portion 154 is changed. Therefore, in the first embodiment of the present invention, the ring gear 77a of the bevel gear 77 is not caught at all on the hexagonal bar 74. Therefore, the housing 130 and the brackets 73 and 75 are destroyed and stringed. Shrinkage 76 destruction also does not occur at all. Yet, in the present invention, the rotational force of the pinion gear 77b is transmitted to the filter cloth suspension shaft 76 as it is through the universal joint 150.

On the other hand, the rail 120 extends in parallel with the hexagon bar 74 at the bottom of the hexagon bar 74. The front end of the rail 120 is fixed to the front plate 12, and the rear end of the rail 120 is fixed to the back plate 14. In addition, the rail 120 is inserted into the guide groove 132 provided on the lower surface of the bevel gear housing 130. The upper portion of the rail 120 which is in contact with the bevel gear housing 130 in the guide groove 132 is lining treatment, which is the bevel gear housing 130 to slide smoothly in the front and rear direction along the rail 120. To make it possible.

As described above, when the hexagonal bar 74 rotates, the ring gear 77a of the bevel gear 77 also rotates. The upper rail 120 rotates the bevel gear housing 130 at all even though the ring gear 77a rotates. It performs the function of holding the bevel gear housing 130 to maintain the posture as it is.

In order to increase the dehydration capacity of the filter press 100, when the filter plates 30 are placed a lot, the length of the hexagonal bar 74 is inevitably lengthened. In this case, the hexagonal bar 74 has its own weight and various bevel gears 77. Due to the weight and weight of the various bevel gear housing 130 is bound to sag down. By the way, the rail 120 as described above supports the weight of the hexagonal bar 74 itself, the weight of the bevel gears 77 and the weight of the bevel gear housings 130, the upper rail 120 is the hexagonal bar 74 ) Will also prevent sag.

Previously, the guide groove 132 is provided on the lower surface of the bevel gear housing 130, and the rail 120 is inserted into the guide groove 132. However, the guide groove 132 may be provided on the side surface of the bevel gear housing 130 (for example, the left surface of the bevel gear housing 130 in the case of FIG. 4). Even in this case, the rail 120 serves to prevent sag of the hexagon bar 74 and to hold the bevel gear housing 130.

The housing stopper 160 is provided to extend in the front-rear direction from any one of front and rear surfaces of the bevel gear housing 130. 3 and 4 illustrate an example in which the housing stopper 160 extends forward from the front surface of the bevel gear housing 130.

In addition, all of the housing stoppers 160 provided in each bevel gear housing 130 have the same length. In addition, the length of the housing stopper 160 is such that the distance between the bevel gear housings 130 which are adjacent to each other when the filter plates 30 abut in the present invention is matched with the filter plates 30 in the conventional filter press 10. It is set to be equal to the distance between the bevel gear housings 130 that are adjacent to each other when they touch, that is, "a conventional separation distance when closing."

Therefore, when the housing stopper 160 of one bevel gear housing 130 is in contact with the neighboring bevel gear housing 130, the distance between the two bevel gear housing 130 is the same as the above "distinguishment conventional distance when closing." Done. For example, when all four filter plates 30 of FIG. 3 abut, the right bevel gear housing in which the housing stopper 160 of the right bevel gear housing 130 located second from the front is located first from the front. In contact with 130, the distance between the first and second right bevel gear housings 130 is equal to the "distance of the prior art when closing."

In the related art, the bevel gear housings 130 are fixed to the left and right brackets 73 and 75 of the filter plate 30 so that the bevel gear housings 130 are also automatically rearward when the filter plates 30 are pushed backwards in contact with each other. Pushed in turn. However, in the present invention, the filter plates 30 are pushed backward while contacting in turn as in the prior art, and the bevel gear housings 130 are pushed backward while contacting with the housing stopper 160 in turn.

The housing stopper 160 may be replaced or used with a shock absorber (not shown). Shock absorbers (such as koba industrial showbars) are designed to receive elastic forces in the direction in which the piston is withdrawn from the cylinder. When the piston receives an external force, the piston is introduced into the cylinder while overcoming the elastic force, and when the external force disappears, the piston returns to its original position by the elastic force. The usual length of the shock absorber is set slightly longer than the length of the housing stopper 10. And the stroke of the shock absorber is set to the distance of the length of the shock absorber minus the length of the shock absorber when the distance between the bevel gear housings 130 is "the conventional separation distance in closing."

When such a shock absorber is used, the bevel gear housing 130 exerts an external force on the piston while being pushed backwards while contacting the piston of the shock absorber, which causes the piston to enter the cylinder slightly, but the length of the shock absorber is bevel gear housings. Only 130 is drawn until the distance between the above "closed conventional distance in closing".

The towing chain 110 connects the neighboring bevel gear housings 130, all of the same length. And the length of the traction chain 110 is the distance between the bevel gear housings 130 that are adjacent to each other when the filter plates 30 in the open state in the conventional filter press 10, that is, the conventional separation at the time of opening. Distance ". Therefore, when all four filter plates 30 of FIG. 3 are fully spaced apart, that is, in the open state, the distance between the right bevel gear housings 130 located in the first and second positions from the front is the above- Is the separation distance ".

Conventionally, the bevel gear housing 130 is fixed to the left and right brackets 73 and 75 of the filter plate 30, so that the bevel gear housings are pulled forward while the filter plates 30 connected to the chain 22 are sequentially dropped. 130 was also automatically towed forward. However, in the present invention, the filter plates 30 connected by the chain 22 are pulled forward while falling in order as in the prior art, and the bevel gear housings 130 connected by the towing chain 110 are separate from the filter plates 30. In turn, towing forward.

The pressing plate 20 is coupled to the support 16 so as to slide in the front and rear direction between the front plate 12 and the rear plate 14 as in the prior art, and through the chain 22 and the front filter plate 30 and The left and right brackets 22 and 24 are connected to each other, and the rods 42 of the hydraulic cylinder 40 are fixed to the left and right sides of the upper surface.

In addition, in the present invention, as shown in FIG. 3, the upper left bracket 22 is connected to the foremost left bevel gear housing 130 and the towing chain 110, and the upper right bracket 24 is foremost right bevel gear housing. 130 is connected to the towing chain (110). Therefore, when the pressure plate 20 is advanced by the operation of the hydraulic cylinder 40, the front filter plate 30 is pulled forward and the front left and right bevel gear housings 130 are pulled forward, and then the filter plates 30 at the rear thereof. ) And left and right bevel gear housings 130 are sequentially towed forward.

In addition, in the present invention, the left bracket 22 is provided with a protrusion 22a protruding rearwardly, in which the stopper 160 of the foremost right bevel gear housing 130 is fitted with the right bracket 24. When it comes in contact with the stopper 160 of the foremost left bevel gear housing 130. Therefore, when the pressure plate 20 is reversed by the operation of the hydraulic cylinder 40, the front filter plate 30 is pushed backwards and the front left and right bevel gear housings 30 are pushed backwards, and then the rear filter plates ( 30 and the left and right bevel gear housings 30 are pushed backwards in sequence.

In FIG. 3, the front right bevel gear housing 130 is provided with the protrusion 22a at the upper side of the front filter plate 30 at the left bracket 22, but if the front left bevel gear housing 130 is the front filter plate ( If at the top of 30, the upper projection 22a will be provided in the right bracket 24.

In addition, in the present invention, the upper left and right brackets 22 and 24 slidably penetrate the rail 120.

Meanwhile, in the anti-foam filter cloth mobile filter press 100 according to the second embodiment of the present invention, the universal joint 150 of the first embodiment has a flexible shaft 250 as shown in FIGS. 5 and 6. Is replaced by.

As is well known, the flexible shaft 250 is provided to be able to bend in all directions while being provided so that rotation of one end 252 is transmitted to the opposite end 254 as it is. In the second embodiment of the present invention, the first end 152, which is one of both ends 252 and 254 of the flexible shaft 250, is fixed to the left and right ends of the filter cloth suspension shaft 76, It is fixed alternately from side to side. Therefore, if the first portion 252 of the flexible shaft 250 is fixed to the left end of the filter cloth suspension shaft 76 in one of the filter cloth suspension shafts 76 adjacent to each other, the other filter cloth suspension shaft 76 It is fixed at the right end.

The end of the flexible shaft 250, which is not coupled to the filter cloth suspension shaft 76, that is, the second end 254, is fixed to the rotation shaft 77b-1 of the pinion gear 77b. . Therefore, when the pinion gear 77b rotates, the rotation is transmitted to the filter cloth suspension shaft 60 through the flexible shaft 250, so that the filter cloth suspension shaft 76 also rotates. The rotation shaft 77b-1 of the pinion gear 77b faces outwardly so that the pinion gear 77b can be comfortably coupled to the second end 254 of the flexible shaft 250.

In the second embodiment of the present invention, the connection between the bearing housing 130 and the left and right brackets 73 and 75 is disconnected, and only the left end or the right end of the filter cloth suspension shaft 76 is connected to the pinion gear 77b of the bevel gear 77. Since only the flexible shaft 250 is connected, even if left and right twist and / or tilt of the filter plate 30 occurs, only the bending phenomenon of the flexible shaft 150 occurs. Therefore, in the second embodiment of the present invention, the ring gear 77a of the bevel gear 77 is not caught at all on the hexagonal bar 74. Therefore, the housing 130 is broken, the brackets 73 and 75 are broken, and Suspension 76 destruction also does not occur at all. Yet, in the second embodiment of the present invention, the rotational force of the pinion gear 77b is transmitted to the filter cloth suspension shaft 76 as it is through the flexible shaft 250.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Various modifications and variations can be made within the equivalent scope of the claims to be described, and the above-described embodiments may be variously combined.
