Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a water / purifier backwashing apparatus for wastewater treatment of tangent electric discharge machining, for example.

[Conventional technology]

In general, water purifiers are those that filter out contaminants in the water with a filter material inside the machine to derive clean water. However, after a long-time filtering action, the contaminants in the water stick to the filter medium and harden, which significantly reduces the effect of the filtering action. Therefore, the water purifier must be regularly cleaned.

Although not shown, conventional water purifier cleaning methods include cleaning outside the machine and back cleaning inside the machine. That is, the former is to remove the filter medium from the inside of the machine to the outside and wash it, and then store it again in the water purifier. Also, the latter does not take the filter media out of the machine,
Under the condition that this is housed in the body, running water is injected in the opposite direction to wash the inside filter material.

[Problems to be solved by the invention]

The conventional water purifier cleaning method has the following problems.

The former cleaning method outside the fuselage requires a lot of labor and time for handling when taking the filter out from the fuselage to the outside or storing the filter again in the fuselage.

The latter method of back-flushing inside the fuselage can wash the filter medium by injecting running water in the opposite direction, but it is difficult to wash quickly even if many control valves are added with this conventional method. However, there was a problem that foreign matter in the water stuck to the filter material.

The present invention solves the above-mentioned problems of the prior art. That is, the purpose of this invention is to make a large number of backward flowing water in one direction by the operation of the control valve to make a link-shaped flowing water, and to induce the control valve to
It is an object of the present invention to provide a water / purifier backwashing device which can swirl an agitator to loosen a filter medium and thereby perform washing in the reverse direction easily, quickly and reliably.

[Means for solving problems]

The feature of this invention is that the bottom is opened and the flow ports are provided and the flow ports are provided at equal intervals on the four sides of the side wall. A vertical sleeve pipe was hung vertically on the section, and a plurality of notches communicating with the outside of the lower end were provided in the lower half of the vertical sleeve pipe, and a conduction hole was provided in a part of the side wall between the water stop rods. A control valve that rotatably accommodates a valve body, and a stirrer in which a large number of vertical claws are provided at intervals on the stirring claw that radially projects a stirring claw on the axis of the long vertical axis, One or more movable blades are provided in the axial direction on one circumferential surface of the horizontal and vertical pipe sections, and a fountain clearance is formed in parallel on the two sides of each movable blade, and this fountain clearance is reduced from the inner circumference to the outer circumference. That is, a large number of water leakers communicating with the tapered space are arranged concentrically in the upper, lower, middle and lower parts of the body.

[Action]

When cleaning the water purifier with the back-cleaning device with the above-mentioned configuration, the four flow ports that project in advance on the side wall of the valve seat are divided into entry, water discharge, drain, and communication, and pipes according to their use. Then, when the valve body is turned 90 degrees by operating the handle, the conduction hole provided between the water stop rods of the valve body communicates with the drain flow port, so that the valve side wall has three sides. The drain stop and the water outlet for the drain are closed by the water stop rod attached to the inlet, and the inlet for inlet leads to the outlet for communication which is connected to each of the lower water leakers. Therefore, the running water introduced from the entry port is
As it is, it is jetted in the same direction on the bottom side of the fuselage from the lower water leaker through the communication flow port, and ring-shaped running water is created and flows upward, so that the filter material on the bottom side can be loosened. Further, when the handle is operated to rotate the stirrer after a lapse of a certain period of time, the stirring claw and the vertical claw are moved in position, and the filter medium can be loosened in the opposite direction. This repetitive operation enables quick and reliable washing in the opposite direction. Immediately after that, when the handle is operated to rotate the valve element to the original position, the flow passage introduced is aligned with the through hole of the valve element. After that, it flows into the airframe from above, and thus the filtration state can be smoothly restored.

The top of 11 is loosely fitted and thrown above it, and the lower end is opened to the same plane as the valve body 12 to provide a flow port 112 that communicates with the hollow part of the inner region by the same diameter. There is.

A shank-shaped handle 1 is provided on the outer top of the valve body 12.
21 is attached, and by operating this handle 121,
The valve body 12 is assembled into a unitary body in a state where it can rotate in the circumferential direction with the valve seat 11 as a guide. A part of the side wall of the valve body 12 between the water stop rods 122 and 122 according to this aspect is removed from the upper end to the lower end except the top part, and the lower flow port 112 and the inner diameter region of the valve seat 11 are located at this position. A communication hole 123 is provided for communication. A vertical sleeve tube 124 having an open lower end is vertically provided at the top axis of the valve body 12. The lower half portion of the vertical sleeve pipe 124 communicates with the outer side of the lower end and is provided with notches 125, 12 for engaging the localization fork 21 of the agitator 2 described later at this position.
5 are provided to face each other.

As shown in FIG. 3, in the stirrer 2, radial stirrer claws 22 with vertical claws 23 are axially fitted at intervals on the axis other than the upper and lower ends of the long vertical axis to form a batch. ing. In this case, the stirring claw 22 is formed in a state in which a large number of taper strips are radially projected around the long vertical axis, and a large number of vertical claws 23 are provided at intervals on each surface portion. The filter material (not shown) can be stirred and loosened.

As shown in FIG. 4, the water leaker 3 has a plurality of small-diameter pipes continuously arranged in a bent manner in a horizontal direction and a vertical direction, and one side surface of each pipe portion has a shaft for the pipe portion.

There is.
In this case, on both sides of each movable vane 31, there is formed a narrow water jet clearance 32 in parallel. This fountain gap 3
2 communicates with an inner tapered space S formed so as to gradually shrink from the inner circumference to the outer circumference of the small-diameter pipe portion. The fountain clearance 32 disappears when the movable blade 31 moves in the inner diameter direction and widens when the movable blade 31 moves in the outer diameter direction. (Figs. 5 and 6
Further, a cap 33 for closing the opening is attached to the opening position of the pipe portion on the tip side of the water leaker 3. The large number of water leakers 3 according to this aspect are individually mounted and used for each radial port 51 of the fixed base 5 described later.

The control valve 1, the stirrer 2 and the large number of water leakers 3 according to the above-mentioned main parts are arranged as follows with respect to the upper, middle and lower parts of the machine body A which is vertically long and has the shape of a tank with legs that are vertically closed. . That is, as shown in FIG. 7, the lower half of the control valve 1 is mounted at the top position of the machine A so that the lower half of the control valve 1 penetrates the top of the machine A due to its external force. From the inside of the machine body A, the water separation port 4 is concentrically fitted to the lower end of the control valve 1.

Further, the stirrer 2 is housed at internal positions except the bottom side of the machine body A, and its upper end shaft portion is loosely inserted into the vertical sleeve pipe 124 of the control valve 1 and then each notch 1 of this vertical sleeve pipe 124 is inserted.
The localization fork 21 is engaged with 25. In this case, since the width of the notch 125 is larger than the thickness of the localization fork 21, it is set so that the stirring operation cannot be transmitted to the stirrer 2 unless the handle 121 is rotated 90 degrees or more. The lower end shaft portion of the stirrer 2 is loosely inserted in the bearing by the shaft center hole portion of the fixed base 5 installed on the base plate 6 corresponding to the inner bottom portion of the machine body A, whereby the stirrer 2 rotates in the circumferential direction. Is arranged so that it is possible.

Further, at each radial opening 51 of the fixed base 5 arranged on the base plate 6 in the airframe A, the water leaker 3 is provided for each opening, and the movable blade 3 is provided.
The fountain clearances 1 in which 1 is located are mounted in the radial direction by connecting the base end openings so as to be arranged in the same direction, and are fixed so as to be a radial arrangement as a whole.

According to the above aspect, the following piping is provided in the upper and lower parts of the machine body A in which the control valve 1, the agitator 2 and the many water leakers 3 which are the main parts are arranged concentrically in the upper, middle and lower parts. .

That is, as shown in FIG. 7, FIG. 9, and FIG. 10, each of the flow ports 111 provided on the four sides of the side wall of the control valve 1 has an inlet pipe 111A at the flow port 111 at the position where the cleaning water is introduced.
Is connected, and the water outlet pipe 1 is connected to the flow port 111 at the opposite position.
11B is connected. Further, the communication pipe 1 is provided at the flow port 111 on one side orthogonal to the inflow pipe 111A and the water discharge pipe 111B.
The upper end of 11D is connected, and the flow port 11 at the opposite position is connected.
A drain pipe 111C for draining water is connected to 1.
The lower end of the communication pipe 111D as described above is connected to the axial hole of the fixed base 5 that is opened in the base plate 6 that is the bottom side of the machine body A, and the water / purifier backwashing device as a whole as a whole is cleaned. Is composed. (See FIG. 7) When the water purifier is washed by the back washing device having the above-described structure, first, the valve body 12 of the control valve 1 is rotated 90 degrees by the operation of the handle 121. Conduction hole 1 provided between the water stop rods 122
As shown in FIG. 9, 23 communicates with the drain pipe 111C, so that the drain pipes 111C and the water outlet pipe 111B are closed by the water stopper rods 122 mounted on the three sides of the side wall of the valve body 12 to prevent running water. An inlet pipe 111A for introduction is connected to each of the water leakers 3 in the lower portion through a fixing base 5 to form a communication pipe 111.
It will lead to D. Therefore, the flowing water introduced from the inflow pipe 111A is directly ejected from the respective water leakers 3 in the lower part in the same direction on the inner bottom side of the machine body A through the communication pipe 111D. Even if the handle 121 is turned 90 degrees as described above, the notch 125 in the vertical sleeve tube 124
Since the width of the stirrer is formed to be large, the agitator 2 is not rotated at this point.

At the time of jetting of running water by the above, each fountain clearance 3 of the leaker 3
Since 2 are uniformly oriented in the same direction, the flowing water ejected from each fountain clearance 32 is, as shown in FIG.
It is made into a ring shape of different sizes, and flows upward, which allows the filter material on the bottom side to be loosened. That is, as shown in FIG. 5, each movable blade 31 during filtration before washing is pressed from the outside by a filter material (not shown) and is concave toward the inner diameter of the pipe portion. Since the running water is jetted from the inner diameter of the pipe portion to the outer diameter direction, the pressure of the jetted water causes each movable blade 31 to be in a convex state from the outer peripheral surface of the pipe portion, as shown in FIG. Therefore, since the tapered space S is also expanded, the jetting amount of the flowing water from the gap 32 is increased due to the widening of the fountain gaps 32 communicating with the tapered space S, thereby enhancing the ring-shaped flowing water jet. Easy, quick backwash can be done.

When the handle 121 is operated to rotate the stirrer 2 after a lapse of a predetermined time (after about 20 seconds or more), each stirring claw 22
The vertical claw 23 and the vertical claw 23 are moved in position to loosen the filter medium in the opposite direction. It is possible to smoothly and reliably complete the washing in the opposite direction by repeating the above-mentioned jetting of the ring-shaped running water from below and the rotation of the agitator 2.

Immediately after completion of the above-described backwash operation, the handle 121
When the valve body 12 is rotated to the original position by operating the
Since the conduction hole 123 of the valve body 12 is aligned with 11A as shown in FIG. 10, the flowing water introduced from the inflow pipe 111A communicates with the hollow portion of the inner area of the valve body 12 and the lower flow passage 11
It will flow into the inside of Aircraft A from above via 2,
As a result, the filtration state can be recovered easily and quickly again.
