DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention is a chronicle centrifugal separator designed to separate liquid phase from a slurry phase containing minute solidus materials. Traditionally, centrifugal separator has been use in the waste water treatment industry, the pharmaceutical industry and the purification of raw materials industry. These sort of centrifugal separator relied on a high speed centrifugal action. A slurry containing minute solidus materials has been introduced on a mesh screen. Liquid phase has been separated from the slurry. At the same time the solidus material has been separated out by a chronicle mesh screen type centrifuge.

Examples of Japanese patents SO36-1386. SO39-20693 as well as S055-51558. These traditional centrifugal separator had common problems. The liquidus phase has been separated by the rotation of the mesh screen and then transferred to a receiver tank. The solidus material was transferred to a opening which followed the mesh screen into a receiver chamber. The minute solidus phase frequently blinds often the mesh screen openings. During the continuous introduction of the slurry, the mesh screen had to be replaced because of the decreased separation deficiency. Japanese patent SO55-51558 describes a system where a cleanser fluid is injected to the mesh screen. However, the mesh screen was blinded but at a reduced extent, making replacement of the mesh screen inactiveable.

Accordingly, traditional centrifugal separator is not practical as a general consumer product. Traditionally, the slurry had been introduced at a reduced amount through the supply pipe toward the center of the scraper blade. In this case the slurry feed of pipe must be a fine pipe. The present invention solves this problem because there is no blinding of the mesh screen even though the mesh screen is not replaced. Another purpose of the present invention is to increase the amount of slurry in order to enhance the separation efficiency.

The present invention utilizes the centrifugal action at high speed where the slurry is introduced. Because of the centrifugal force, the mesh screen is connected to the shaft. The periphery of the opening of the mesh screen is clamped to the upper and lower portion of the grill. The grill can slide up and down toward the direction of the centrifugal action. At the same time the mesh screen may turn in combination. The shaft supports the moveable parts. At the same time, the shaft houses the support for the moveable parts, which are fixed on the elevator plate. This elevator plate is attached to the elevator cylinder.

Another investigation of this invention is that the slurry is introduced into this housing by means of a pipe installed on the cover. Through this pipe the slurry is introduced and separated.

In order to facilitate the elevator mechanisms the bearings attachments are utilized. The bearing attachment fixes the height of the rotating shaft. At the same time, it turns the inside of the screen out. This elevator attachment contacts the mesh screen which is turned over in order

i iac to remove the solid phase materials. This solid phase removal mechanism contains a blade. These are the essential features of the present invention.

The grill is clamped on a fixed screen at the lower inside. The opening periphery of the mesh screen is attached to the screen plate by clamping on the lower inside periphery. The shaft connected to the sliding attachment could be hexagonly in shape, considering the sliding mechanism is in the direction of the shaft. During the rotation of the mechanism, the inside of the mesh screen turns to the outside. As a result materials blinding off the screen is separated out by centrifugal action. In this way the replacement of the mesh screen is unnecessary.

The solidus material separates off the mesh screen and is collected at a collection channel. The collection blade collects the solidus materials from the collection channel. This blade is fixed to the πng gear The ring gear rotates because of the centrifugal gear and motor attachment Because of this ring gear, the slurry pipe attached toward the center of the shaft is enlarged making the feed rate of the slurry increased.

The first figure is the overall view of the present invention The slurr> material is introduced through Figure 1 These raw materials introduce pipe 1 which freely falls down through the raw material overflow prevention pipe 2. The 7 chronicle mesh screen introduces the slu The mesh screen 7 has stationary screen 5 and 6 clamped at its lower peπpheπ The upper periphery has grill 9 & grill 8 by way of clamping The stationary screen plate 5 and 6 are fixed by not 11 but. to a shaft 24. The mesh screen 7 contains multiples of bolts by way of tight clamping. Use of these bolts fall under public knowledge and is not subject of present invention

The raw material introduction pipe 4 is fixed to the upper part of the stationary screen 5 In this case a constant gap is maintained between the introduction pipe #4 and the upper stationary screen 5. The raw mateπal is passed through multiple openings 46. Accordingly, the end note in 11 and the centrifugal spread material passes through the opening 46 of the rav. material introduction pipe 4. And by way of the centrifugal force sprayed over the inside surface of mesh screen 7. The mesh screen 7 is rotated by way of the rotation shaft 24 to which a pulley 32 and belt 34 are affixed. The centrifugal pulley 33 and the centrifugal 41 provide the power. Belt 34 is a V shaped belt type. Timing belt was similar can also be used for the power source. The Centrifugal motor 41 is connected to rotation shaft 24. And the shaft 28 is connected to a stationary bolt 31. The shaft 28 is connected to bearing 35 in the housing 26. The housing 26 and the centrifugal motor 41 is supported by the elevator plate 38. Elevator plate 38 is vertically movable because of the air cylinder 42. Air cylinder 42 is supported by the plate 36 located at the upper part of the case. This makes it possible to support the elevator plate 38. In order to control the height of the elevator plate 38 a spacer 43 is installed.

Air cylinder 42 moves the elevator plate 38 maintaining the steadiness by the guide post 39 at least at 4 corners. These are guided by guide roller 40.

Accordingly, the elevator plate 38 and the stationary shaft 24 are activated by the air cylinder 42. This is because the shaft 24 and the stationary screen 5 and 6 elevates and docents the mesh screen 7. The same can turn the mesh screen 7 inside out or outside in. In further details the air cylinder 41 rotates at high speed by the centrifugal motor 41. separating the slum . elevating the mesh screen 7. turning the screen upside down during the operation.

While doing this the solidus material attached to the inside surface of the mesh screen #7 is separated out. The mesh screen 7 and the upper grill 8 and 9 are clamped to the former rotates. In this case the lower grill 8 and grill supports 10 supports the grill 8. The support grill 10 is connected to the shaft 24 which rotates with the shaft 27 and the centrifugal motor 41. The grill 9 and 8 are connected to the clamping nut 13. Shaft 27 with bearing 30 are housed by housing 25. The housing 25 is supported by a plate 36. restricting the movement of shaft 27. Shaft 27 and shaft 24 movement are better managed by use of a multigon shaft material. Shaft 24 can be a hexagon in shape, therefore, in further details, the hexagon shape shaft number 24 in conjunction with shaft number 27 facilitates the sliding action during the rotation.

The raw material feed pipe 1 and raw material guide pipe 4 facilitates the separation of the slurry by way of a high speed mesh screen 7. The fluid is then collected by the liquid collection chamber 15, which is provided at lower periphery at mesh screen 7. The collected liquid is then transferred to the next phase by exiting exit number 23.

On the other hand the solidus material follows through the angled surface of the mesh screen 7 upwards and it is collected at collection chamber 14. While doing this, the solidus material is collected also at the screen opening which then lowers the separation efficiency.

To overcome this problem the present invention facilitate a mechanism whereby the mesh screen 7 is turned upside down by use of the air cylinder 41. periodically. On the other hand the solidus material collected at collection 14 is merged at one location by the action of the blade 21. This material subsequently is transferred to the next process by the screw conveyer 22. The blade 21 is installed at four directions, ss viewed from the rotation shaft. Here the blade 21 is fixed to the lower portion of the ring gear 19. The ring gear 19 rotates by ways of multiples of roller 20 and is supported by the motor support plate 16. This ring gear 19 interfaces the centrifugal gear 18. then rotates with the power supplied by motor 17 which is supported by support plate 16.

The part 3 is the cover for the centrifugal separator and part 45 is the clamp which supports the cover to the motor. The part 44 is a wheel and is located in the lower part of plate 37. Figure 2 shows the mesh screen, the shaft, the upper and lower grill and its cross sectional view. The lower grill 8 has the mesh screen 7. The mesh screen 7 is clamped to the lower part of grill 9 and 8. The lower periphery plate is clamped in between the stationary plate 5 and 6. The grill 9 and 8 are firmly secured by lower grill 8 and nut 13. Grill 9 and 8 are secured on grill support 10. The pexagonal rotation shaft 24 and shaft 27 are connected. In this case the shaft 27 slides toward the shaft direction without any needs of support. The shaft 24 slides towards the direction of the arrow, turning the mesh screen 7 inside out. This mechanism is shown in figure 3.

Figure 3 A illustrates a situation where the mesh screen is blinded off with fine minute solidus materials. Figure 3B shows the mechanism whereby the solidus material is removed from the mesh screen. Air cylinder 42 periodically removes the solidus materials from mesh screen 7. The solidus materials is collected at the collection chamber 13.

Figure 4 shows the structure of the blade. Blade 21 and ring gear 19 are at a 90 degree angle. Ring gear 19 and centrifugal gear 18 are tooted together and are at a rotational motion which is facilitated using the power supplied by motor 17. In this case the ring gear 19 is supported by multiples of roller 20. Roller 20 is supported by support plate 16 as shown on figure 1.

Accordingly, the present invention unlike the traditional centrifugal separator takes the raw materials introduced, maintaining the extra space toward the direction of the shaft. The raw materials overflow prevention pipe is installed toward the center. In this way the raw material does not overflow. The raw material inlet pipe can be enlarged making the amount of input higher and making the separation efficiency higher. Figure 5 shows the mechanism by which the solidus materials collected at collection channel 14 is scraped by the blade 21 to be transferred to the next process. A donut shape collection channel 14 is located at the outside periphery at screen 7. Blade 21 collects the solidus material from the collection shaft 14 and exits through exit 12.

Subsequently, screw conveyer 22 transfers the solidus materials to the next process. Part
