Description

FIBER FILTRATION APPARATUS WITH VERTICAL GUIDE PIPE}

The present invention relates to a fiber filter device in which a spiral guide is applied to a vertical pipe, and more specifically, in adjusting the air gap of the fiber yarn applied to the filter, the upper hook of the fiber yarn is fixed through a cylinder device driven in the vertical direction. By reciprocating the rotated upper plate in the vertical direction and rotating in one direction, the voids of the entire fiber media layer are controlled uniformly and uniformly throughout the fiber filter device in which the spiral guide is applied to the vertical pipe to maximize the filtration efficiency. It is about.

In general, the filter is a device for draining clean treated water by filtering the contaminated water with a filter, it is gradually increasing in size for filtration of large rivers, filtration of factory wastewater.

As a filter used for this purpose, a pore-controlled fiber filter is typically used. The pore-controlled fiber filter uses a bundle of fiber yarns having fine filaments and arranges them on a flow path to use them as a filtration material. It is called media. The fibrous media has the advantage that the pores formed by the filaments are easily controlled by physical control, so that not only the filtration performance is excellent, but also the cleaning is easy and the life is long. In particular, the removal efficiency of each particle size, SS, BOD removal efficiency and the like has been proved to have an excellent effect compared to other filtration methods.

As a related art with respect to a fiber filter, there is a "filtering apparatus having a variable filter layer" of Patent Registration No. 10-0241198. The prior art is a pore-controlled fiber filtration device that relaxes and compresses the fiber yarn in the vertical direction by using a piston, and there is a problem that the fiber filter material is broken due to an increase in the fatigue of the fiber material due to excessive tensile force when used for a long time. In addition, the method of controlling the voids by pulling the fiber yarn in the vertical direction has a problem that the filtration efficiency is lowered due to the phenomenon that the fibrous layer is not formed uniformly and the fiber yarns are spread.

In addition, there is a conventional pull up and down compression method using an air cylinder.

In the case of the vertical pull compression method using an air cylinder, a method of compressing the fiber yarn by reciprocating motion of the upper cylinder is to control the air gap by simply pulling the fiber yarn in a vertical direction and relaxing and pressing, wherein the cylinder force is applied to the upper part of the fibrous layer. The filtration efficiency is deteriorated due to the phenomenon that only the fiber is delivered to the intermediate layer and is not delivered to the intermediate layer.

In particular, in the case of a vertical pull compression method using a conventional air cylinder, since the air cylinder is located on the upper part of the filter, a space constraint occurs in that the height and the stroke height of the air cylinder are increased.

Hereinafter, preferred examples are provided to aid in understanding the present invention. However, the following examples are merely provided to more easily understand the present invention, and the contents of the present invention are not limited by the examples.

1 is a view showing the configuration of a fiber filter device 100 is applied to the spiral guide in a vertical pipe according to an embodiment of the present invention.

Referring to Figure 1, the fiber filter device 100 is applied spiral guide in a vertical pipe according to an embodiment of the present invention is large filter tank 110, the rotating shaft 120, the cylinder portion 130, guide pipe 140 , A strainer 150, a rotating upper plate 160, and a fixed lower plate 170 are configured.

Here, the strainer 150 is covered with a side of the fibrous media consisting of the fiber yarn bundle (1), wherein the fiber yarn bundle (1) may mean a fiber bundle made of fine filaments.

The filtration tank 110 is a hollow cylindrical structure, and forms a space for filtering the contaminated raw water introduced into the interior to be discharged to the outside.

More specifically, the inside of the filtration tank 110 is provided with a fiber yarn bundle (1) for wrapping the body of the strainer 150 to be described later in the longitudinal direction, the contaminated raw water introduced into the voids between the fiber bundle (1) Can be filtered and discharged to the outside.

The filtration tank 110 is preferably made of a pressure tank. The reason is that if the backwater is not properly performed due to deterioration of water quality of the contaminated water or equipment failure, the pressure inside the filtration tank 110 is rapidly increased, and therefore, the filtration tank 110 should be able to operate normally even at an increased pressure. . In addition, if the filtration tank 110 can withstand high pressure, it is because the increase in the filtration flux has the advantage of treating a larger amount of contaminated water with the same filtration area.

On the other hand, such a filtration tank 110 may be configured to include a fixed stand (110a), backwash water outlet (110b), contaminant water inlet (110c), dual function pipe (110d) and backwash air inlet (110e).

The fixing stand 110a serves to fix the strainer 150 inside the filtration tank 110 and is formed in a tubular shape in which the inside is empty. Therefore, air introduced through the reverse air inlet 110e to be described later may be introduced into the strainer 150 through the fixing base 110a.

The backwash water outlet 110b is installed above the filtration tank 110 and serves as a passage through which the backwash water flows out. The polluted water inlet 110c is installed at the lower side of the filtration tank 110 and serves as a passage through which the polluted water is introduced from the outside. In addition, the dual function pipe (110d) is installed on the lower side of the filtration tank 110 to serve as a passage for performing both functions outflow and backwash water inflow.

This is to solve the limitation of the installation space generated when the piping for the treatment water outflow and the piping for the backwash water inflow separately. On the other hand, the treated water here means water that is contaminated by the fibrous yarn bundle (1) to be clean.

The backwash air inlet 110e is a pipe that serves as a passage through which the backwash air flows into the filtration tank 110, which will be described in more detail with reference to FIG. 2.

2 is a view showing in detail the lower portion of the filtration tank 110 shown in FIG.

Referring to Figure 2, the backwash air introduced into the filtration tank 110 is sprayed in the form of a bubble in the backwash water introduced through the backwash air inlet (110e) is moved to the top along the flow of backwash water, the fiber bundle ( 1) to hit the surface. As a result, the backwasher gives a constant pressure vibration (shake) to the fiber bundle 1, and as a result, the filtered debris particles adhered to the surface of the fiber yarn bundle 1 come off and backwash with the backwash water. It is discharged to the outside of the filtration tank 110 through the outlet (110b). In other words, the fiber yarn bundle 1 is washed by the complex action of backwashing water and backwashing air.

In addition, the present invention may further include a backing air perforated plate (110f) formed a plurality of holes to allow the backwashing air introduced through the backwashing air inlet (110e) to be introduced into the filter tank (110).

1 again, the rotary shaft 120 is installed in a vertical direction to penetrate the upper side of the filtration tank 110 inward or outward. This will be described in more detail with reference to FIG. 3.

Referring to Figure 3, the rotary shaft 120 is located in the vertical direction to enable the inlet and withdrawal in the vertical direction from the upper side of the filter tank 110, wherein the upper end of the rotary shaft 120 is the horizontal axis of the cylinder portion 130 It is connected to the support (130g).

More specifically, the rotary shaft 120 is provided on the lower side of the upper rotary shaft 120a and the upper rotary shaft 120a, the upper end of which is connected to the horizontal axis support (130g) and the rotary upper plate 160 is fixed And 120b.

The upper rotary shaft 120a is positioned outside the filtration tank 110 and is connected to the horizontal shaft support 130g through the ball joint 120a-1 provided at the upper end portion. At this time, the upper rotary shaft 120a may be freely rotated below the horizontal support 130g by the ball joint 120a-1.

The lower rotary shaft 120b is positioned inside the filtration tank 110 and has a length for fixing the rotary upper plate 160 as it extends downward to have a predetermined length.

On the other hand, the horizontal axis support (130g) connected to the upper rotary shaft (120a) is a vertical reciprocating linear movement by the cylinder action of the cylinder portion 130.

More specifically, the cylinder portion 130 is inside each of the first and second cylinders 130a and 130b and the first and second cylinders 130a and 130b provided in the vertical direction from the outer side of the filtration tank 110. First and second pistons 130c and 130d and first and second pistons 130c and 130d which are provided and reciprocated in the first and second cylinders 130a and 130b, respectively. And horizontal transverse supports 130g connected to the upper end portions of the second piston rods 130e and 130f and the first and second stone rods 130e and 130f, respectively.

In this case, the first and second cylinders (130a, 130b) are formed on the side of the filtration tank 110, not the upper surface, through which the overall height of the fiber filter device 100 is applied to the spiral guide to the vertical pipe is reduced Has

Here, the cylinder 130 may be a kind of pneumatic cylinder device or a hydraulic cylinder device may be applied.

Therefore, when the first and second pistons 130c and 130d are moved upward in the upward direction by pneumatic or hydraulic pressure, the first and second piston rods 130e connected to the first and second pistons 130c and 130d, 130f) moves up, and thus the transverse support 130g also moves up, such that the upper rotary shaft 120a connected to the center of the transverse support 130g through the ball joint 120a-1 is moved up. do.

On the contrary, when the first and second pistons 130c and 130d move downward, the first and second piston rods 130e and 130f connected with the first and second pistons 130c and 130d move downward. As the horizontal axis support 130g is also moved downward, the upper rotary shaft 120a connected to the center of the horizontal axis support 130g through the ball joint 120a-1 is moved downward.

On the other hand, the side of the upper rotary shaft 120a is provided with a guide pipe 140 surrounding the upper rotary shaft 120a.

Guide pipe 140 is formed in a hollow cylindrical shape surrounding the side of the upper rotary shaft (120a) having an inner diameter larger than the diameter of the upper rotary shaft (120a), protrudes from the side of the upper rotary shaft (120a) inside The spiral guide groove 140a to which the rotated protrusion 120a-2 is coupled is formed in an oblique line along the longitudinal direction. Accordingly, when the upper rotary shaft 120a is vertically reciprocated, the upper rotary shaft 120 is moved along the length direction of the spiral guide groove 140a while the rotary protrusion 120a-2 is coupled to the spiral guide groove 140a. Rotation of 120a may be guided.

Looking at the spiral guide groove 140a formed in the guide pipe 140 in more detail, the spiral guide groove 140a is formed in the longitudinal direction (up and down in the drawing) of the guide pipe 140, but twisted in a diagonal rather than a straight form It is in the form of a gin. Two guide grooves 140a are provided in the guide pipe 140 because two rotation protrusions 120a-2 protruding from the side of the upper rotation shaft 120a are provided.

That is, the two rotary protrusions 120a-2 protruding from the side of the upper rotary shaft 120a correspond to a state of being engaged with the spiral guide groove 140a, respectively, and the upper rotary shaft ( When 120a) is moved upward or downward, it automatically rotates.

At this time, the rotary top plate 160 is fixed to the lower end of the lower rotary shaft 120b, since the lower rotary shaft 120b is rotated together with the upper rotary shaft 120a, the rotary upper plate 160 also moves up and down in the vertical direction. Will rotate simultaneously.

The rotating top plate 160 is provided with a plurality of upper projections 160a on which the upper hooks of the fiber yarn bundles 1 are caught, and the number of the upper protrusions 160a corresponds to the number of the fiber yarn bundles 1. Is formed.

When the top plate 160 of the rotary top plate 160 is moved up and down and rotated in the vertical direction while the upper hook 160 of the fiber bundle 1 is caught in the top protrusion 160a, the fiber bundle ( 1) is stretched in the vertical direction and twisted while rotating. That is, the vertical movement and rotation of the rotary top plate 160 in this vertical direction is to induce tension and twisting of the fiber yarn bundle 1.

In one embodiment, the upper side of the rotating upper plate 160 by covering the upper side of the upper plate 160, the upper locking ring fixing plate 160b to prevent the upper locking ring caught on the upper projection 160a is separated Can be prepared.

Meanwhile, the state in which the rotating shaft 120 and the rotating upper plate 160 are driven by the driving of the cylinder 130 will be described in more detail with reference to FIG. 4.

4 is a view illustrating a driving state of the rotary shaft 120 and the rotary upper plate 160 by the driving of the cylinder unit 130 illustrated in FIG. 3.

Referring to FIG. 4B, in the state of FIG. 4B, the first and second pistons 130c and 130d are moved upward in the first and second cylinders 130a and 130b, respectively. As the second piston rods 130e and 130f rise, the horizontal axis support 130g rises upward.

Accordingly, the upper rotary shaft 120a connected to the horizontal support 130g and the ball joint 120a-1 and the lower rotary shaft 120b connected to the upper rotary shaft 120a are upwardly raised.

At this time, as shown in Figure 4 (c), because the rotary projection (120a-2) protruding on the side of the upper rotary shaft 120a is engaged with the spiral guide groove 140a, the upper and lower rotary shafts 120a, 120b) and the rotating upper plate 160 are raised in the upward direction while rotating.

On the other hand, when the rotating upper plate 160 moves in the downward direction, the process proceeds in the order of FIGS. 4 (c), 4 (b), and 4 (a).

2, the strainer 150 is installed in the lower part of the filter tank 110 by the fixing unit 110a, and an accommodation space 150a is provided on the upper side for accommodating the lower end of the lower rotating shaft 120b. On the lower side, a lower locking ring (not shown) of the fiber yarn bundle 1 is fixed and fixed, but the lower plate 170 is not rotated.

The strainer 150 is a hollow cylindrical structure, and a plurality of through holes 150b are formed on a surface thereof.

The fixed lower plate 170 is connected to the lower side of the strainer 150, and a plurality of lower protrusions 170a are provided on which the lower hook ring (not shown) of the fiber bundle 1 is provided, and the number of the lower valleys 170a is provided.

When the rotary top plate 160 is moved up and down in the vertical direction, correspondingly, the fiber bundle 1 is twisted in the vertical direction at the same time. That is, the upward movement and rotation of the rotating upper plate 160 in the vertical direction and the fixing of the fiber yarn bundle 1 of the fixed lower plate 170 induce tensioning and twist generation of the fiber yarn bundle 1.

In one embodiment, the lower side of the fixed lower plate 170 by covering the lower side of the fixed lower plate 170 to prevent the lower locking ring (not shown) caught in the lower protrusion (170a) to prevent the separation hook fixing plate ( 170b) may be provided.

On the upper side of the strainer,
Fibrous filtration with a spiral guide applied to the vertical pipe, characterized in that the receiving space for receiving the lower end of the lower rotary shaft vertically moved in the downward direction by the first and second piston rod is received inwardly Device.
The method of claim 1,
And an upper hook ring fixing plate and a lower hook ring fixing plate covering each of the rotating upper plate and the fixed lower plate, wherein the spiral pipe is applied to the vertical pipe.
The method of claim 3,
When the first and second piston rod is vertically moved in the upward direction, the rotary shaft and the rotary top plate are vertically moved upward and simultaneously rotate in one direction by the combination of the rotation protrusion and the spiral guide groove. The gap between the fiber yarn bundles is reduced by the tensile force generated in the fiber yarn bundles as the upper yarn hooks coupled to the rotary top plate are pulled in the vertical direction and the fiber yarn bundles are twisted.
When the first and second piston rods are vertically moved downward, the rotary shaft and the rotary top plate are vertically moved downward and are rotated in opposite directions by the combination of the rotation protrusion and the spiral guide groove. And the voids between the fiber yarn bundles are increased while the twist and the tension generated in the fiber yarn bundles are removed.
The method of claim 2,
And a backwash air porous plate having a plurality of holes formed therein to allow the backwash air introduced through the backwash air inlet to be introduced into the filtration tank.
