Description

    The present invention relates to, for example, a filter device used for removing sludge from a cutting fluid of a machine tool and an operation method thereof.

  Conventionally, in general, the filter is unavoidably clogged. In that case, it was disposable, backwashed, or taken out from the place of use and washed with high pressure water at another place.

  In the case of a single use, the consumption cost is high and a large amount of waste is generated. In the case of backwashing, the clogged filter is clogged, so that the liquid for backwashing is a liquid amount that oozes out of the filter, and it is difficult to obtain sufficient cleaning power. When the hydraulic pressure was increased to enhance the cleaning power, there was a risk of the filter breaking. When cleaning in another place, the work is cumbersome and inefficient.

  An object of the present invention is to provide a filter device having a high filter cleaning effect and an operation method thereof.

  The filter device according to the present invention is different from a filter radial direction, a vertical cylindrical filter supported rotatably around a vertical axis, a cleaning liquid nozzle directed from the same direction as the filter radial direction to the outer surface of the filter, and A rotating liquid nozzle directed from the direction toward the outer surface of the filter, and the filter is rotated by the pressure of the liquid ejected from the rotating liquid nozzle.

  In the filter device according to the present invention, in order to clean the filter, the liquid is ejected toward the outer surface of the filter while rotating the filter. There is no need for backwashing, and the filter can be washed while in use. Therefore, a filter device having a high filter cleaning effect can be obtained.

  Further, when the filter is a pleated filter formed so that the inner and outer folds of the pleat are arranged in the circumferential direction, the outer surface of the filter effectively exerts a resistance force against the pressure of the liquid, so that the filter is effectively rotated. I can do that.

  Moreover, if the resistance member with respect to the liquid pressure is provided on the outer surface of the filter, any type of filter can be used regardless of the type of filter.

  In addition, the filter, the cleaning nozzle, and the rotation nozzle are disposed in the filtrate tank, and supply means for supplying the filtrate in the filtrate tank to the washing nozzle and the rotation nozzle, respectively. In this case, the liquid to be filtered in the tank to be filtered can be circulated and used, and the quantitative balance of the liquid to be filtered need not be taken into consideration. Furthermore, no special equipment is required outside the filtrate tank for cleaning the filter.

  Moreover, it is preferable that the filtrate tank is arrange | positioned in parallel with the to-be-filtrated liquid tank, and is provided with the conveyance means which conveys the filtrate passed through the filter to a filtrate tank.

  In addition, a filter, a cleaning nozzle, and a rotating nozzle are arranged in the filtrate tank, and a filtrate tank is arranged in parallel with the filtrate tank, and the filtrate in the filtrate tank is used for washing. You may provide the supply means to each supply to a nozzle and the nozzle for rotation.

  Moreover, it is preferable to provide a transport means for transporting the filtrate that has passed through the filter to the filtrate tank.

  In the operation method of the filter device according to the present invention, when the filtrate or filtrate is supplied to the cleaning nozzle and the rotation nozzle, the conveyance of the filtrate by the conveying means is stopped.

  In the operation method of the filter device according to the present invention, when the filter is washed, the liquid to be filtered cannot be passed through the filter, so that the filter can be washed efficiently.

  According to the present invention, a filter device having a high filter cleaning effect and an operation method thereof are provided.

  Embodiments of the present invention will be described below with reference to the drawings.

  Referring to FIG. 1, a filtrate tank 11 and a filtrate tank 12 are arranged in parallel. A filter unit 13 is accommodated in the liquid tank 11 to be filtered. The filter unit 13 is surrounded by a vertical sectional rectangular casing 14 from above and below and from the left and right. A filtration pipe 15 extends from the filter unit 13 to the filtrate tank 12. The filtration pipe 15 is provided with a filtration pump 16. An upper bearing 17 is supported at the center of the top wall of the casing 14. A lower bearing 18 is supported at the center of the bottom wall of the casing 14 so as to correspond to the upper bearing 17. On the left and right side walls of the casing 14, a lower end portion of an inverted U-shaped cleaning pipe 19 is fixed so as to straddle the filter unit 13 and protrude upward from the casing 14. The cleaning pipe 19 is provided with a cleaning pump 20. One end of the cleaning pipe 19 is opened, and the other end is closed.

  The filter unit 13 includes a filter body 31, a pleated filter 32 held on the outer surface of the filter body 31, and a collect pipe 33 fixed to the inner surface of the filter body 31.

  The filter body 31 includes a vertical cylindrical main body 41, a horizontal ring-shaped top cover 42 that is detachably attached to the upper end surface of the main body 41, and a horizontal that is detachably attached to the lower end surface of the main body 41. A ring-shaped bottom cover 43 is provided.

  An annular communication passage 51 is provided in the middle of the height of the outer peripheral surface of the main body 41.

  The top cover 42 covers the entire upper end surface of the main body 41 and projects radially outward therefrom. A downward bent edge 61 is provided at the overhanging end of the top cover 42. A downward holding groove 62 is formed by the upper end portion of the outer peripheral surface of the main body 41, the protruding portion of the top cover 42, and the downward bent edge portion 61. The bottom cover 43 has a structure in which the top cover 42 is turned upside down, and has an upward bent edge 63. Similarly to the downward holding groove 62, an upward holding groove 64 is formed by the lower end portion of the outer peripheral surface of the main body 41, the protruding portion of the bottom cover 43, and the upward bent edge portion 63.

  The pleated filter 32 is manufactured by pleating an elastic material such as paper, fiber, and metal mesh. The pleated filter 32 is formed into a cylindrical shape as a whole so that the inner and outer creases are aligned along the circumferential direction. Is formed.

  An upper end plate 71 is fixed to the upper end portion of the filter 32, and a lower end plate 72 is fixed to the lower end portion of the filter 32. The upper end plate 71 is fitted in the downward holding groove 62, and the lower end plate 72 is fitted in the upward holding groove 64, respectively. The upper end plate 71 and the lower end plate 72 have the same structure.

  The method of fixing the filter 32 and the both end plates 71 and 72 is as follows. As the material of the end plates 71 and 72, liquid rubber or elastic resin (urethane that can be poured in liquid such as urethane rubber or silicon rubber) is adopted. The end portion of the filter 32 formed into a cylindrical shape is inserted into a cavity corresponding to end plates 71 and 72 of a mold (not shown), and in this state, the above material is poured into the cavity and solidified. As a result, both end portions of the filter 32 are embedded in the end plates 71 and 72 by a depth corresponding to the thickness thereof, and are fixed integrally with the end portions.

  The collect pipe 33 has a vertical main pipe 81 extending on the filter axis and supported by the upper bearing 17, and extending radially outward at equal intervals from the lower end of the main pipe 81 and connecting the tip to the connecting passage 51. It consists of four branch pipes 82.

  A vertical rotation shaft 83 is provided at the lower end of the main pipe 81 so as to extend downward. The lower end portion of the rotating shaft 83 is supported by the lower bearing 18.

  An upper cleaning liquid nozzle 91, a rotating liquid nozzle 92, and a lower cleaning liquid nozzle 93 are sequentially provided from the top to the bottom near the end of the cleaning pipe 19 on the closed side. The upper cleaning liquid nozzle 91 and the lower cleaning liquid nozzle 93 are straightly directed to the filter outer surface from the same direction as the filter radial direction. The rotating liquid nozzle 92 is directed to the outer surface of the filter at a predetermined angle from a direction different from the filter radial direction.

  When the filtration pump 16 is operated, the filtered filtrate in the communication passage 51 is sucked up and the filtrate to be filtered outside the filter 32 is allowed to pass through the filter 32. At this time, the inner part of the filter 32 is opened only at the communication passage 51, but the adjacent creases inside the pleats of the filter 32 are connected in series in the vertical direction. The filtrate is passed through the filter in the height direction and filtered.

When the cleaning pump 20 is operated, the liquid to be filtered is sucked into the cleaning pipe 19, and the sucked liquid to be filtered is straight from the upper cleaning liquid nozzle 91 and the lower cleaning liquid nozzle 93 to the outer surface of the filter from the filter radial direction. In this way, the contaminants adhering to the outer surface of the filter are blown away. On the other hand, the liquid to be filtered is sprayed from the rotating liquid nozzle 92 to the outer surface of the filter at a predetermined angle from the filter radial direction, and the filter is rotated by the pressure. For example, when the pressure in the cleaning pipe 19 is 2 to 3 kg / cm 2 , the rotational speed of the filter unit 13 is about 50 rpm.

  The operation control pattern is shown in FIGS. In FIG. 3, the filtration is repeated with a certain stop interval. Washing is performed while filtration is stopped. On the other hand, as shown in FIG. 4, the cleaning may be continuously performed regardless of whether the filtration is performed or stopped.

  Here, since the experiment was conducted on the cleaning ability, specific examples thereof will be shown with numerals. It is assumed that the pattern shown in FIG. 3 is filtered for 3 minutes and washed for 30 seconds. A filter having an eye size of about 5 μm was used. At the beginning of the operation, the flow rate of the filtrate was 88 l / min. With the passage of time, a change of about several l / min was observed, but there was almost no decrease in the flow rate. On the other hand, when the washing was not performed, the flow rate of the filtrate was 91 l / min at the beginning of the operation, but when the first hour passed, it decreased to 83 l / min, and then several l per hour. It was 76 l / min when it decreased gradually and about 8 hours passed. An experiment was similarly performed on a filter having an eye size of about 0.5 μm. When washing was performed, the flow rate of the filtrate was 79 l / min and remained constant from the beginning of operation. On the other hand, when washing was not performed, the flow rate of the filtrate, which was 79 l / min at the start of operation, dropped to 51 l / min after about 8 hours had passed.

  As shown in FIG. 5, the cleaning pipe 101 may be supplied with a filtrate from the filtrate tank 12 in place of the above-described filtrate to be filtered, and cleaned with the filtrate. In this case, the cleaning pipe 101 extends from the filtrate tank 12 to the filtrate tank 11.

  FIG. 6 shows an example of means for collecting the contaminants blown off from the filter. The filtrate tank 111 includes an upper cleaning tank unit 112, an intermediate cyclone tank unit 113, and a lower recovery tank unit 114. A filter unit 13 is accommodated in the upper cleaning tank portion 112. The pollutants blown off from the filter are collected downward by the centrifugal force in the intermediate cyclone tank unit 113 and stored in the lower collection tank unit 114. The lower collection tank unit 114 is provided with a discharge port 115.

  7 and 8 show modifications of the filter unit 13. As the filter, a cross-sectional cylindrical filter 121 having a smooth outer surface is employed instead of the pleated filter. In this case, a large number of blades 122 are provided at regular intervals on the upper edge of the outer surface of the filter 121. These blades 122 serve as resistance members against the pressure of the liquid ejected from the rotating liquid nozzle 123. The rotating liquid nozzle 123 is provided in the cleaning pipe 19 so as to be at the same level as the blade 122. Below the rotating liquid nozzle 123, three cleaning liquid nozzles 124 are provided in a vertical line.
