Description

[0001] MOVABLE FILTER CLOTH TYPE FILTER PRESS WITH SUSPENDING ROD SEPRATED FROM FILTER PLATE [0002]

The present invention relates to a filter cloth movable filter press capable of lifting and lowering a filter cloth between filter plates. More particularly, the present invention relates to a filter cloth movable filter cloth having a structure in which a contraction axis supporting the filter cloth above the filter plate is separated from the filter plate, Filter press.

Generally, the sewage discharged from the home or factory is sent to the sewage treatment plant, and the sludge generated in the treatment process 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 and an electroosmotic dehydrator according to the operation principle.

The filter press is a device for removing sludge cake (dewatered sludge) from the filter chamber after pressurizing the filtrate sludge provided between the filter plates which are in close contact with each other to separate the filtrate from the sludge. Such a filter press is classified into a filter cloth movable filter press and a filter cloth fixed filter press depending on whether a filter cloth provided to surround the filter chamber between the filter plates is raised or lowered or fixed to the filter plate.

During dehydration in the filter cloth movable filter press, the filtrate separated from the sludge is passed through the filter cloth surrounding the filter cloth and then discharged to the outside of the filter plate via the surface protrusions of the filter plate. When the dewatering is completed, the sludge cake is separated from the filter cloth by the separation of the filter plates, thereby being separated from the filter cloth by a free fall. After the filter plates are separated from each other, the two filter cloths that have formed the furrows descend downward, where the sludge cake is separated from the filter cloth. When the separation of the sludge cake is completed, the filter cloth rises again, and then the filter plates are closely contacted. Then, two filter cloths located between the filter plates form the filter chamber, and the sludge to be dewatered is pressed into this filter chamber.

As described above, in the filter cloth movable filter press, since the filter cloth must move in the vertical direction, the filter cloth lifting means is provided. Conventional filtration apparatus elevating means includes a pair of hexagonal bars and a plurality of contraction shafts. The pair of hexagonal bars are spaced apart from each other in the width direction (lateral direction) of the filter plate, and are rotatable about the rotation axis extending along the arrangement direction (front-rear direction) of the filter plate, and are located at the upper portions of the filter plates. The plurality of contraction shafts are provided so as to extend in the left-right direction, to be spaced apart from each other in the front-rear direction, and to be rotatable about a rotation axis extending in the left-right direction. These contractions are coupled to the hexagonal rods through the bevel gears, respectively. Sprockets are provided at both ends of the contraction, and a chain hanging filter cloth hangs in the sprocket.

When the hexagonal rods rotate in the forward direction, the contraction shafts also rotate in the forward direction, and the filter cloth is raised at this time. On the other hand, when the hexagons rotate in the opposite direction, the contractions also rotate in the opposite direction, and the filter cloth falls.

The filter cloth movable filter press having the above-mentioned filter cloth lifting means is disclosed in Korean Patent No. 10-0541328 (Filter Press) and Korean Patent No. 10-1308939 (Filter Filter Removable Filter Press).

On the other hand, as disclosed in Korean Patent No. 10-1545547 (filter cloth mobile filter press) and Korean Patent No. 10-1572055 (filter cloth filter mobile filter), there is also known a filter cloth movable filter press having no hexagonal bar.

Korea Patent No. 10-0541328 (filter press) Korean Registered Patent No. 10-1308939 (filter cloth movable filter press) Korean Patent No. 10-1545547 (filter cloth movable filter press) Korean Patent No. 10-1572055 (filter cloth movable filter press)

In a filter cloth movable filter press having a hexagonal rod, the hexagonal rod passes through the ring gear of the bevel gear. The head shrinkage is rotatably supported on a bracket fixed to left and right ends of the upper surface of the filter plate, and one end of the neck shrinkage is fixed to the pinion gear of the bevel gear. Therefore, when the filter plates are opened and closed, the contraction and the bevel gear are moved together with the filter plate in the forward and backward directions. At this time, the ring gear of the bevel gear linearly moves along the hexagonal bar.

However, since the opening and closing plates of the filter plates are made by pushing or pulling the hydraulic cylinder at the center of the pressure plate located at the front of the frontmost filter plate, there is a difference in the linear movement distance of the filter plates and the linear movement distance of the upper and lower ends. When the difference is large, the ring gear is caught in the hexagonal bar and the linear movement of the filter plates can not be smoothly performed, resulting in a problem that the filter press is destroyed.

Accordingly, it is an object of the present invention to provide a technique that prevents the ring gear from being caught in the hexagonal bar, even if there is a difference in the linear travel distance between the left and right ends of the filter plates, and ultimately, .

The present invention relates to a filtering device comprising: a contraction axis provided to extend in a left-right direction at an upper portion of each of filter plates arranged in the front-rear direction, The hexagonal bar extending in the forward and backward directions from the left and right sides of the upper and the lower filter plates is rotatably supported on the left and right sides of the contraction, Shrink housing; A ring gear coupled to the hexagonal bar so as to penetrate the hexagonal bar and a pinion gear fixed to an end portion of the left and right ends of the hysteretic shafts where the present shrinkable housing is not fastened and meshing with the ring gear; A bevel gear housing rotatably surrounding a rotary shaft of the ring gear and a rotary shaft of the pinion gear; A rail which supports the bevel gear housing and the hull shrink housing such that the front and rear ends thereof are fixed so as to be parallel to the hexagonal rod and the front and rear ends of the bevel gear housing and the hull contraction housing are slidable; And a pulling chain connecting the neighboring bevel gear housing and the current shrinking housing, and a filter bag movable filter press having a separate contraction.

The filter cloth moveable filter press having the contraction axis separated from the filter plate has a structure in which both the frontmost filter plate and the bevel gear housing fastened to the left and right sides of the contraction axis located on the uppermost portion of the forefront filtration plate and the contraction- And a pushing plate provided to push or pull forward.

According to the present invention, even if the filter plate is tilted leftward and rightward and / or tilted up and down, the posture of the contraction is maintained unchanged, so that the phenomenon that the ring gear provided on the bevel gear at one end of the contraction axis does not stick to the hexagonal bar does not occur.

Further, according to the present invention, although the filter sheet and the upper shrinkage thereon are separated from each other, the upper filter sheet and the contraction shrinkage are simultaneously pressed and pulled at the time of operation of one hydraulic cylinder.

<Typical Filter cloth  Removable filter press>

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

In general, 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.

The frame includes a front plate (12) and a back plate (14) which are apart from each other in the front-rear direction. The frame also includes a pair of support rods 16 spaced laterally, both ends of which are fixed to the front and rear plates 12 and 14, respectively.

The pressure plate 20 is positioned between the front plate 12 and the back plate 14 as shown in FIG. 1, and is coupled with the support 16 so as to perform a sliding motion along the front-rear direction. The pressure plate 20 is connected to the forefront filter pipe 30 through a chain 22.

The filter plates 30 are positioned 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 perform sliding movement along the front-rear direction. In addition, adjacent filter plates 30 are connected by chain 22.

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

When the hydraulic cylinder 40 is operated and the rod 42 is pulled out in the above-described filter mobile filter press 10, the pressure plate 20 is moved toward the back plate 14 while being pushed by the rod 42. At this time, the filter plates 30 are moved toward the back plate 14 while being pushed by the pressure plate 20, and reach the closed state (closed plate state) in a state of being in close contact with each other as shown in FIG. On the other hand, when the hydraulic cylinder 40 is operated and the rod 42 is pulled in the closed state, the pressure plate 20 is pulled by the rod 42 and moved toward the front plate 12. At this time, the filter plates 30 connected to the chain 22 are moved by the pressure plate 20 toward the front plate 12, and then they are opened from each other as shown in FIG. 1 (b).

When the sludge is press-fitted into the filter plates 30 in the state where the filter plates 30 are closed, dehydration of the sludge is performed. In order to dewater the sludge, a filter cloth 50 is required, and the filter press 10 includes a plurality of filter cloths 50.

As shown in FIG. 2, the filter cloth 50 is provided in a form in which a pair of bags are overlapped with each other. An upper end rod 56 is provided at the upper end of the filter cloth 50. A first lower end rod 58a is provided at the lower end of one of the pair of cannons and a second lower end rod 58b is provided at the lower end of the remaining cannon Lt; / RTI &gt;

Further, a sludge passing plate 52 is provided at the upper center of the filter cloth 50. The sludge passing plate 52 has a sludge passing hole 52a through which the pressurized sludge passes. The sludge passing plate 52 is also provided with a sludge supplying path 52b positioned at a part of the inner circumferential surface of the sludge passing hole 52a. The sludge supplying path 52b allows the sludge to flow from the sludge passing hole 52a It can be fed into a pair of guns.

The filter cloth 50 thus formed is positioned between the filter plates 30 as shown in FIG. The sludge passing hole 52a of the sludge passing plate 52 communicates with the sludge passing hole 34 of the filter plate 30 and the sludge passing hole 34 of the filter cloth 50 is partially (hereinafter, referred to as a "contaminated portion") of the portion (b) is pressed by the filter plate 30 and abuts on the pair of bags, A female room 54 is provided, which is a space between the pair.

When the sludge is pushed in the closed state, the sludge passes through the sludge passing hole 52a of the sludge passing plate 52, the sludge passing hole 34 of the filtering plate 30, and the sludge supplying passage 52b of the sludge passing plate 52, And is supplied to the filter chamber 54 of all the filter cloths 50. [ In the filtration chamber 54, dewatering of the sludge is performed by the pressure input. At this time, the filtrate passes through the filter cloth 50 and the sludge cake remains in the filtration chamber 54. On the other hand, the filtrate having passed through the filter cloth 50 is moved downward along the gap between protrusions (not shown) provided on the retraction surface 32 of the filter plate 30, And is discharged to the outside of the filter plate 30. [

When the sludge is dewatered for a predetermined period of time, the filter plates 30 are opened. At this time, the sludge cake falls freely from the chamber 54. Thereafter, the filter cloth 50 is lowered to remove the sludge cake remaining in the contaminated portion (a) of the filter fabric 50. The filter cloth 50 descending to the lower limit is raised again to its original position. On the other hand, when the filter cloth 50 is moved up and down, the filter cloth 50 is cleaned by the washing water sprayed from the washing water spray tube 92.

For the lifting movement, the filter cloth 50 is connected to the lifting chain 78 as shown in FIG. Specifically, the upper end rod 56 of the filter cloth 50 is coupled to the upper end of the lifting chain 78, and the first and second lower end rods 58a and 58b of the filter cloth 50 are connected to the lifting chain 78, As shown in FIG. All of the filter cloths 50 can simultaneously ascend and descend when the coupling relationship between the filter cloth 50 and the lifting chain 78 is as described above.

The lifting chain (78) is suspended at both ends of the neck shrinkage (76). Therefore, when the hunting shrinkage 76 rotates in the forward direction, the filter cloth 50 descends. When the hunting shrinkage filter 76 rotates in the reverse direction, the filter cloth 50 rises.

As shown in Fig. 1, one end of the hinge shaft 76 is coupled with a bracket 75 fixed to one end of the upper surface of the filter plate 30 through a bearing. The opposite end of the neck shrinkage 76 is coupled to the bevel gear 77 while being rotatably coupled to a bracket (not shown) fixed to the opposite end of the upper surface of the filter plate 30.

The bevel gear 77 moves along the hexagonal bar 74 when the filter plates 30 are moved in the forward and backward directions and transmits the rotational force of the hexagonal bar 74 to the hull axis 76. 1, the hexagonal rod 74 is connected to the driving shaft 72 through another bevel gear 72a, and the driving shaft 72 is connected to the front plate 12 And is connected to the motor 70. And the rear end of the hexagonal bar 74 is rotatably coupled to the upper end of the rear plate 14. [

When the motor 70 is operated in the filtration chamber 10, the filter cloth 50 ascends or descends while the drive shaft 72, the hexagonal bar 74, and the head shrinkage 76 rotate.

&Lt; Having a contraction contour separated from the filter plate Filter cloth  Removable filter press>

Hereinafter, characteristics of a filter movable filter press 100 having a contraction axis separated from a filtration plate according to the present invention compared to the general filter movable filter press 10 will be described with reference to FIGS. 3 and 4, The same reference numerals are used for the same members.

3 and 4, the filter cloth 100 according to the present invention includes a neck shoe 76, a necked shoe housing 140, a bevel gear 77, a bevel gear housing 130, A rail 120, and a traction chain 110. As shown in Fig.

The hinge shafts 76 are provided to extend in the left-right direction from the upper portions of the filter plates 30 arranged in the front-rear direction. A sprocket 76a is provided on the right and left sides of the neck shrinkage 76 so that the lifting chain 78 hanging the filter cloth 50 hangs thereon.

Conventionally, a bracket 75 (not shown) for supporting the left and right ends of the neck shrinkage 76 is fixed to the upper left and right ends of the upper surface of the filter plate 30. However, in the present invention, the brackets 75 (not shown) are not provided, and the left and right ends of the neck shrinkage 76 are supported by the hull contraction housing 140 and the bevel gear 77. Specifically, same.

The hysteretic shrink housing 140 is coupled with the left and right ends of the hysteretic shrinkage 76 and alternately turns left and right in the forward and backward directions as shown in Figs. Therefore, if the present contraction housing 140 is engaged with the left end of the contraction axis 76 in any one of the neighboring contraction shafts 76, the other contraction axis 76 is engaged with the right end thereof.

The hysteresis shrinking housing 140 also engages with the left or right end of the hysteretic shrinkage 76 via a bearing (not shown). Therefore, even if the hip shrinkage 76 rotates around an axis extending in the left and right direction, the hip shrinkage housing 140 maintains its posture.

The present shrinking housing 140 has a through hole 144 through which the hexagonal bar 74 penetrates. A bearing (not shown) is interposed between the inner surface of the through hole 144 and the outer surface of the hexagonal bar 74 have. Therefore, even if the hexagonal bar 74 rotates about an axis extending in the front-rear direction, the contraction-resistant housing 140 maintains its posture.

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 hexagonal bar 74 so as to penetrate the hexagonal bar 74. Therefore, the ring gear 77a may rotate together with the hexagonal bar 74 and move in the front-rear direction 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 around the axis extending in the left-right direction. The rotary shaft 77b-1 of the pinion gear 77b is fixed to an end portion of the left and right ends of the hysteresis shrinkage shaft 76 where the present shrinkage housing 140 is not fastened. Therefore, when the pinion gear 77b rotates, the contraction 76 also rotates.

The bevel gear housing 130 surrounds a rotary shaft (not shown) of the ring gear 77a so as to be movable along the hexagonal bar 74 together with the ring gear 77a. A bearing (not shown) is provided between the bevel gear housing 130 and the rotation shaft of the ring gear 77a. Even if the ring gear 77a rotates together with the hexagonal bar 74, the bevel gear housing 130 does not rotate The posture can be maintained as it is.

The bevel gear housing 130 also surrounds the rotary shaft 77b-1 of the pinion gear 77b. At this time, a bearing (not shown) is also provided between the bevel gear housing 130 and the rotary shaft 77b- City). Therefore, even if the pinion gear 77b rotates, the bevel gear housing 130 is not rotated.

The bead gear 76 is connected to the bevel gear 77 while being supported by the left and right brackets 75 (not shown) on the upper surface of the filter plate 30. However, in the present invention, the neck shrinkage 76 is supported by the bevel gear 77 and the hysteretic shrink housing 140, and the upper left and right brackets 75 (not shown) are not provided on the upper surface of the filter plate 30, (76) and the filter plate (30) are separated from each other. Therefore, in the present invention, the conventional problem of the ring gear 77a of the bevel gear 77 being stuck in the hexagonal bar 74 does not occur at all, which will be described in detail as follows.

When the filter plates 30 are moved from the open state to the closed state, the front filter plates 30 move backward and the filter plates 30 are in contact with each other. In this process, A slight or more advance than the end, that is, left and right side deviations occur. This right and left deviation occurs even when the filter plates 30 are moved 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 side tilts but also the up-and-down side tilts. That is, since the filter plate 30 has a structure in which the center of gravity thereof is located at a lower position, when the filter plates 30 in an open state are sequentially pushed backward, the tops of the filter plates 30 are slightly lower Tilting occurs, that is, upward and downward tilting occurs.

However, if the contraction 76 is connected to the bevel gear 77 while being supported by the left and right brackets 75 (not shown) on the upper surface of the filter plate 30 as in the prior art, The tilting occurs as it is in the contraction 76. And the upper left and right tilting and / or the vertical tilting are generated and accumulated in the various filter plates 30, the ring gear 77a is tightly caught in the hexagonal bar 74, The pressing of the filter plates 30 to the rear causes the problems such as the breakage of the bevel gear 77 or the breaking of the bracket 75 (not shown) or the breakage of the contraction 76.

However, in the present invention, since the string shrinkage 76 is supported by the bevel gear 77 and the shrinking housing 140 while being separated from the filter plate 30, the left and right tilting and / or tilting of the upper and lower sides of the filter plate 30 The contraction 76 can be maintained in the posture without being influenced by the upper left and right side tilting and / or the upper and lower side tilting at all. Therefore, in the present invention, even if the filter plate 30 is tilted leftward and rightward and / or tilted up and down, the ring gear 77a of the bevel gear 77 does not catch on the hexagonal bar 74, The conventional problems such as fracture (77), destruction of the bracket (75, not shown), and contraction of the contraction (76) do not occur. However, in the present invention, the rotational force of the pinion gear 77b is transmitted as it is to the contraction shaft 76 as is conventionally done.

Meanwhile, the filter movable filter press 100 according to the present invention includes the rails 120 for supporting the bevel gear housing 130 and the suspension rod housing 140 described above.

The rail 120 extends parallel to the hexagonal bar 74 at the bottom of the hexagonal 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 rear plate 14. [

The rail 120 is inserted into a guide groove 132 provided on the lower surface of the bevel gear housing 130 and a guide groove 142 provided on the lower surface of the hysteretic housing 140. The portions of the rails 120 that come into contact with the housings 130 and 140 in the upper guide grooves 132 and 142 are lined with the housings 130 and 140 along the rails 120 So as to smoothly slip in the direction shown in FIG.

The cross section of the upper rail 120 may be provided in an inverted trapezoidal shape as shown in the drawing, or may be provided in an inverted trapezoid or a rectangular shape although not shown.

The rails 120 support the contraction housing 140 and the bevel gear housing 130 and the upper housings 140 and 130 support the left and right ends of the contraction shafts 76, 120 perform the function of supporting the contraction 76.

As described above, when the hexagonal bar 74 rotates, the ring gear 77a and the pinion gear 77b of the bevel gear 77 rotate, and the present shrinkage 76 also rotates. When the hexagonal bar 74 rotates, 140 also hold the upper housings 130, 140 so that the bevel gear housing 130 and the hysteretic housing 140 can maintain their posture even if the current shrinkage 76 rotates.

In this case, the hexagonal rod 74 has its own weight, a plurality of bevel gears 77, and a plurality of bevel gears 76. In this case, And due to the weight of the various housings 130, 140. The rail 120 supports the hexagonal bar 74 itself, the weight of the bevel gears 77 and the weight of the housings 130 and 140. The upper rail 120 is supported by the hexagonal rods 74 And also performs a sag prevention function.

The towing chain 110 connects the neighboring bevel gear housing 130 and the current-shrinking housing 140. And the length of the pulling chain 110 is set such that when the filter plates 30 are in the open state, the neck shrinkage 76 is located at the top of the filter plate 30. [

The contraction 76 is supported by the left and right brackets 75 (not shown) on the upper surface of the filter plate 30 so that the filter plates 30 connected to the chain 22 are sequentially pulled and pulled forward, 76) were also towed automatically forward. However, in the present invention, the filter plates 30 connected to the chain 22 are pulled forward while falling down in the conventional manner, and the neck shrinkage 76 is transmitted to the bevel gear housings 130 connected to the pull chains 110, The shrink housing 140 is pulled forward together when it is towed forward as it falls in turn. On the other hand, the length of the pulling chain 110 is set such that when the filter plates 30 are placed in the open state, the neck shrinkage 76 is positioned above the filter plate 30.

In the prior art, the contraction shafts 76 are fixed to the left and right brackets 75 (not shown) on the upper surface of the filter plate 30. When the filtration plates 30 are in contact with each other and pushed backward sequentially, the contraction shafts 76 are automatically I was pushed backward one by one. However, in the present invention, the filter plates 30 are pushed rearward while abutting in the same manner as in the prior art, and the bevel gear housing 130 and the hysteretic shrink housing 140, which are alternately arranged in the forward and backward directions, When pushing backward, push it back together. On the other hand, the forward and backward lengths of the haptic contraction housing 140 are set such that the contraction axis 76 is located above the filter plate 30 when the filter plates 30 are placed in the closed plate state.

The pressure plate 20 of the filter cloth movable filter press 100 according to the present invention is coupled with the support table 16 so as to be able to slide in the forward and backward directions between the front plate 12 and the back plate 14, Left and right brackets 22 for slidably passing through the hexagonal bar 74 are provided on left and right sides of the upper surface of the top plate and the rod 42 of the hydraulic cylinder 40 is connected to the front- It is fixed.

3, the left and right brackets 22 of the pressure plate 20 are coupled to the bevel gear housing 130 and the hysteretic housing 140 coupled to the left and right ends of the foremost hysteretic shrinkage 76, And is connected to the chain 110. Therefore, when the pressure plate 20 is advanced by the operation of the hydraulic cylinder 40, the forefront filtration plate 30 is pulled forward and the forefront column shrinkage 76 is pulled forward together with the left and right housings 130 and 140, The rear filter plates 30 and the contraction shafts 76 are pulled forward one after another.
