The present invention relates to a lifting device for a filter assembly, and more particularly, to a lifting device for a filter assembly whose structure is improved to be able to move up and down in conjunction with a water level inside a tank.

Generally, a filter is required for the process of separating the powder and the solution, and the filter has a function of filtering the powder to filter out only the solution according to the difference in particle size of the solution and the powder.

Among the existing filters, the filter having the function of separating the powder and the solution is mainly used in water purifier or chemical separation process, and most of them are in the form of a mesh made of a plurality of holes, and in the tank or the mixing pipeline in which the powder and the solution are mixed It is common to be installed inside.

The conventional filter is mostly fixed to the inside of the tank or transfer line to separate and filter the solution in the mixture of powder and solution.

In addition, in the case of the filter installed inside the tank, it is mainly installed to be fixed to the lower part where the powder is settled, there is a fear that a large number of foreign substances adsorbed on the surface of the filter and the surface is frequently clogged, which causes frequent replacement of the filter There was a problem that a separate equipment is required to separate the foreign matter attached to the surface of the filter.

Therefore, a backwashing process is required to prevent the foreign matter is adsorbed on the surface of the existing filter to block the pores, and the backwashing pressure of the positive pressure during the backwashing process removes the powder remaining in the pores of the filter and back into the tank. It has the function of returning again.

On the other hand, as the backwash pressure of the positive pressure is supplied to the filter side during the backwashing process, it is preferable that the pore size of the filter is varied so that the powder is easily separated from the inside of the pores. There is a need for a material that is flexible and has sheet type material properties.

In addition, since powder is precipitated to the lower side of the tank, a larger amount of powder is deposited on the lower side of the tank than the upper side, so that the lower the end position of the pipe pipe where the filter is located, the greater the amount of powder to be filtered. As a result, the surface of the filter may be clogged quickly.

Therefore, it is preferable that the end of the pipe pipe in which the filter is located is located in the upper part of the tank where the amount of powder to be filtered is small, so that a lifting device for the filter that can be lifted according to the variable water level in the tank is required.

In addition, the present invention further includes a backwashing means for delivering pressure to the filter side by discharging the solution backward from the pipe pipe to the filter side.

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

An embodiment of the lifting device of the filter assembly of the present invention will be described with reference to FIG. 1, the configuration of which is a tank 100 in which a mixture of powder and a solution is mixed and a solution in the mixture in the tank 100. The pipe pipe 250 has a passage function for discharging the gas and a filter 450 for separating the powder and the solution at an end thereof, and is connected to a part of the pipe pipe 250 so as to be stretchable. The expansion pipe 400 for varying the and the pipe pipe 250 is configured to move up and down so as to move up and down.

In more detail, the pipe structure 250 and the expansion pipe 400 is connected to each other in the form of a pipe structure so as not to interfere with the discharge flow of the solution, the expansion pipe 400 is a pipe pipe ( It is a structure that can be stretched and coupled to the inside of the 250).

That is, the pipe pipe 250 is elevated by the lifting means for adjusting the height of the filter 450 installed at one end, the expansion pipe 400 is fitted into the inside of the pipe pipe 250, pipe pipe 250 The inside and outside of the telescopic structure to have a structure that can appear.

In addition, it is preferable to further provide a backwashing means for transmitting pressure to the filter 450 side by discharging the solution in the reverse direction from the pipe pipe 250 to the filter 450 side.

That is, when the backwashing means is attached to the surface of the filter 450 and the pores become clogged, the filter back by supplying air or a solution from the pipe pipe 250 to the filter 450 side to the filter 450 in the reverse direction to the filter It is for leaving the foreign matter attached to the (450) side.

As an example of the lifting means, as shown in Figure 2, a rotatable driven roller 520 is provided on the outside of the tank 100, the belt member (1) to be interlocked in a position spaced upward from the driven roller 520 ( The driving roller 535 connected to the 510 is rotatably connected to the motor shaft 532 of the rotary motor 530, and integrally connected to one side of the belt member 510 to be rotated and a part of the pipe pipe 250. As the belt member 510 rotates, it is configured to be lifted up and down.

This, by coupling a portion of the belt member 510 rotatably rotatable between the drive roller 535 and the driven roller 520 and the fixture 550 for connecting a portion of the outer circumferential surface of the pipe pipe 250 to be integrated with each other, When the belt member 510 is rotated, the pipe pipe 400 is to be raised or lowered together.

However, the up and down movement of the pipe pipe 250 is proportional to the rotation of the belt member 510, but the up and down movement range is shorter than half of the entire length of the belt member 510. This is because the fastener 550 is integrally coupled to the belt member 510 and the pipe pipe 250, and if the belt member 510 is rotated further, there is a risk of damage.

In addition, the moving section of the pipe pipe 250 may be such that the filter 450 is movable to a distance close to the upper and lower bottom surface of the tank 100.

As a second embodiment of the present invention, as shown in Figure 3, a plurality of gears (250a) is formed on a portion of the outer peripheral surface of the pipe pipe 400 in the longitudinal direction, and the gears (250a) of the pipe pipe 250 It has a drive motor shaft 575 to be engaged and is driven to rotate as the external power is applied to the drive motor 570 for elevating the pipe pipe 250 up and down.

At this time, the gear structure of the drive motor shaft 575 and the pipe piping 250 is engaged, the drive motor shaft 575 is a pinion, the gear 250a of the pipe piping 250 is configured as a rack gear rack and pinion In this manner, the pipe pipe 250 may be configured to be lifted up and down.

As shown in FIG. 4, the third embodiment of the present invention has a structure in which the structure is installed at a position spaced apart from the pipe pipe 250, and the rod 610 is upward and downward as the hydraulic or pneumatic pressure is supplied / discharged. An actuator 600 of an elevated hydraulic, pneumatic or electric drive type, and an end of a rod 610 of the actuator 600 are coupled to each other, and a gripping means is provided to grip an outer circumferential surface of the expansion pipe 400.

The gripping means is formed so that the fitting groove 252 is recessed in the outer peripheral surface of the pipe pipe 250, the clamping portion 615 of the shape corresponding to the fitting groove 252 at the end of the actuator rod 610 is Formed.

In addition, Figure 5 shows a fourth embodiment of the present invention, the engaging portion 622 of the tongs shape corresponding to the fitting groove 252 is formed at the end of the rod 610, the rod ( The end of the 610 is further provided with a gripper 620 is integrally coupled.

The gripping tool 620 is integrally coupled to the end of the rod 610 by welding, or has a structure that is integrally coupled to each other using a separate fastening member 630 such as a bolt.

Preferably, the connection structure of the pipe piping 250 and the expansion pipe 400 is composed of a double structure of the outer case and the inner case so as not to interfere with the discharge flow of the filtered solution, and the pipe case 250 is an outer case The end portion of the tongs of the rod 610 or the end of the gripper 620 is to be held on a portion of the).

On the other hand, as a means for controlling the operation of the lifting means, as shown in Figure 7 showing the sixth embodiment of the present invention, a water level sensor for detecting the level of the mixture in the tank 100 and outputs it as an electrical signal ( 710 and a control unit for automatically controlling the elevating operation of the expansion and contraction pipe 400 when the level of the mixture is within a predetermined range after receiving the signal outputted from the water level sensor 710 and comparing it with a predetermined value. 700 may be further provided.

The water level sensor 710 is integrally fixed so as to interlock with the elevated pipe pipe 250, or a plurality of water level sensors 710 are installed on the inner peripheral surface of the tank 100 spaced apart from each other, except that the water level sensor 710 is a tank ( When fixed to the pipe pipe 250 located in the 100 is preferably installed at a position higher than the filter 450.

This is to place the filter 450 at least as close to the water surface as possible so that the water level of the mixture is always higher than the position of the filter 450, so that the powder is precipitated and placed at a high position so as to be spaced as far as possible from the cloudy bottom.

In addition, the present invention is not provided with one filter 450 at the end of the pipe pipe 250, a plurality of filters 450 may be installed to be spaced apart at different heights at the end of the pipe pipe 250. .

In this case, when the vacuum negative pressure is applied to the inside of the pipe piping 250, the vacuum negative pressure is applied to the filter 450 located below or the filter 450 located thereon according to the height of the pipe piping 250. Since the solution is discharged in the tank, it may be possible to control the discharge of the solution.

Reference numeral "200" indicates a vacuum pump for suctioning and discharging the solution in the tank 100 toward the pipe piping 250 side, and "310", "320", "330" indicates the pipe piping 250 The valves respectively installed on the branched pipe side control the operations of the water washing and backwashing means to selectively convert the internal pressure of the pipe pipe 250 into negative pressure or positive pressure.

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

The elevating device of the filter assembly of the present invention may omit the water level sensor 710 and the control unit 700 during manual operation, and if the user supplies an external power source (electric, hydraulic, pneumatic, etc.) to the elevating means, the driving motor In the case of 570, if the motor shaft is rotated in one direction by the rack and pinion gear coupling method, the pipe piping 250 that is the rack gear is raised, and if the motor shaft is rotated in the other direction, the pipe piping 250 is reversed. The lowering operation is performed.

At this time, the expansion pipe 400 has a function to ensure that even if a portion of the pipe pipe 250 is elevated, the remaining portion does not interfere with the lifting force regardless of its movement.

That is, when a part of the pipe pipe 250 is raised, the telescopic structure is interlocked so that the length of the flexible pipe 400 connected to the pipe pipe 250 is extended so as not to affect the lower pipe pipe 250 side. Will be.

In addition, when the belt member 510 is used, when the driving roller 535 connected to interlock with the motor shaft of the rotating motor 530 rotates the driven roller 520 through the belt member 510, the belt member ( The pipe pipe 250 integrally supported by the 510 is moved up and down by the rotation of the belt member 510.

In addition, in the case where the actuator 600 is used, when air or hydraulic pressure is supplied to the actuator 600 in one direction, the rod 610 is lowered to extend, and thus is gripped at the end of the rod 610. Pipe pipe 250 is interlocked with the lowering operation.

On the contrary, when air or hydraulic pressure in the other direction is discharged to the actuator 600 to the outside, the rod 610 is lifted up to contract and the pipe pipe 250 is lifted up.

That is, the pipe pipe 250 having the lifting operation by the lifting means can be moved up or down manually or automatically according to the level of the mixture in the tank 100, and when the water level is high pipe pipe so that the filter 450 close to the water surface By raising the 250, the solution of the upper side of which the powder is relatively thinner than the lower side can be filtered through the filter 450 and then discharged to the outside.

In addition, when the water level is reduced, the pipe pipe 250 is lowered back to the lower side in the tank 100 so that the filter 450 is always positioned at a lower position than the water surface.

In addition, even when the filter 450 is lifted by the lifting means, when foreign matter (powder) adheres to the surface of the filter to block the pores of the filter, the backwashing means is periodically operated to generate a positive pressure solution from the pipe piping 250 side. By supplying to the filter 450 side, it is possible to separate the foreign matter attached to the surface of the filter 450.

On the other hand, Figure 6 shows a fifth embodiment of the present invention, the structure of the expansion pipe 400 is not a telescopic telescopic structure but formed of bellows type, the pipe having a hollow to communicate with the pipe pipe 250 therein It is configured in the form of a (pipe), and the structure is formed in the pleated portion 410 of the flexible stretchable pleated form so that the volume of a portion above the variable according to the lifting operation of the filter 450 in the intermediate portion.

The stretchable pipe 400 may have a fixed structure, except for the portion in which the pleats 410 are formed, or may be configured in the form of a pleat in its entirety to be coupled to the pipe pipe 250.

In addition, the embodiments of the present invention described above can be changed depending on the height and level of the tank 100, the lifting range of the pipe pipe 250 is elevated by the lifting means, the height of the tank is formed to about 1m ~ 10m More preferably, a height of about 2 to 5 m will be preferable.

This is because the height of the tank 100 is at least 1 m or more, so that the precipitation of the powder may be maintained so that the upper and lower boundaries within the tank 100 may be installed due to the width of the tank. This is because the space securing problem and the capacity of the mixture of the powder and the solution contained in the tank 100 must be considered.

On the contrary, the reason why the height of the tank 100 is 10 m or less is that the cost of manufacturing a tank with a height higher than that is not only large, but also considering the capacity of the mixture accommodated in the tank, the capacity is smaller than that. This is because it is more preferable to manufacture a plurality of tanks.

In addition, since another embodiment of the present invention described above may adopt various lifting means described above, duplicate descriptions of the lifting means will be omitted.

As described above, the present invention is improved in structure so that the filter assembly for separating the solution is installed in the tank containing the mixture of powder and solution can be elevated according to the level of the mixture, according to the present invention Since the filter assembly can be lifted and lowered, the powder can be precipitated to the lower side, and the solution can be discharged from the upper side than the turbid lower side, thereby minimizing the adhesion of foreign substances on the surface of the filter and prolonging the replacement cycle of the filter. Has a useful effect.

In addition, when the filter lifting structure of the present invention is adopted in the tank provided with the backwashing means, the lifting structure and the backwashing means of the filter assembly is in parallel has the advantage that the efficiency in the washing process can be further improved.
