After interior clamshell 48 was connected to electric machine assembly 44, first side drive wheel 202 of rotary screen assembly 200 slided on second end 59 of electric machine assembly output shaft 57.Second end 59 by electric machine assembly output shaft 57 inserts in the tubular drive shaft member 220 of the drive shaft openings 235 of inner annular plate 218 and first side drive wheel 202 first side drive wheel 202 is slided on the electric machine assembly output shaft 57, and the key flange 63 of second end 59 of electric machine assembly output shaft 57 inserts in the driving shaft notch 237 of drive shaft openings 235 as mentioned above.Thereafter, the circular extending element 229 that centers on the inner rim assembly 216 of first side drive wheel 202 is placed center hub/spacer 206.In the opening 120 that is limited by the inner wheel hub 230 that center hub/spacer 206 is inserted the first side slotted filter screen 204 the first side slotted filter screen 204 is placed on the center hub/spacer 206 then.In case the first side slotted filter screen 204 is slided on center hub/spacer 206 fully, the first side slotted filter screen 204 will be in abutting connection with the inner edge 215 of the spoke 214 of first side drive wheel 202 and between the inner periphery notch 213 and center hub/spacer 206 of first side drive wheel 202.When first side drive wheel 202 with the first side slotted filter screen 204 is as described above when just being connected to electric machine assembly output shaft 57 fully, first side drive wheel 202 and the first side slotted filter screen 204 will be positioned at clamshell 48.

First side drive wheel 202, the first side slotted filter screen 204 and center hub/spacer 206 as top as described in just assembled after, in central seal 76 is located as shown in Figure 17 and is leaned against on the periphery flange 56 of clamshell 48.Central seal 76 is positioned such that the connection opening 122 of central seal 76 aims at the connection opening 74 of interior clamshell 48.In addition, the outer surface of center hub/spacer 206 will be as shown in Figure 12 in abutting connection with the inner annular face 98 of the scraping part 84 of central seal 76.In the opening 120 that by the inner wheel hub 230 that center hub/spacer 206 inserted second side slotted filter screen 208 limited second side slotted filter screen 208 slided into center hub/spacer 206 on thereafter.By second end 59 that inserts electric machine assembly output shafts 57 via the tubular drive shaft member 220 of the drive shaft openings 235 of inner annular plate 218 and second side drive wheel 210 the second side sieves 208 is connected to housing 42 then, the key flange 63 of second end 59 of electric machine assembly output shaft 57 inserts in the driving shaft notch 237 of drive shaft openings 235 as mentioned above.In addition, circular extending element 229 inserts in the center hub/spacer 206, and the second side slotted filter screen 208 will be in abutting connection with the inner edge 215 of the spoke 214 of second side drive wheel 210 and between the inner periphery notch 213 and center hub/spacer 206 of second side drive wheel 210.In addition, a plurality of securing members 124 insert with assembling rotary screen assembly 200 by the opening in the inner rim assembly 216 of first side drive wheel 202 and second side drive wheel 210 as shown in Fig. 6 and 6A.At this moment figure 18 illustrates the assembling of housing 42 till.At last, jacket 46 in the connection opening 74 ' of central seal 76 and jacket 46 and the central seal 76 connection opening 122 and the connection opening 74 in the interior clamshell 48 aim at, and securing member 126 inserts with clamshell 48, central seal 76 and jacket 46 in being connected by connection opening 74,74 ' and 122.Although summarized specific assembling process in the above, can expect that the assembling quality body concentrates assembly 40 by any way.For example, before the housing 42 that is connected to the concentrated assembly 40 of quality body, it is assembled that rotary screen assembly 200 can be used as single piece.In addition, can expect that the quality body concentrates assembly 40 and can comprise as shown in Fig. 5-6A between the jacket 46 and second side drive wheel 210 and the T shape seal 45 between the interior clamshell 48 and first side drive wheel 202, T shape seal 45 wedging central seal 76, tubular wall 54, first side drive wheel 202 and between the stop member 49 that a side is extended from tubular wall 54 and central seal 76, tubular wall 54 ', second side drive wheel 210 and between the stop member 49 that opposite side extends from tubular wall 54.

In case housing 42 is assembled as mentioned above, the quality body will have by central seal 76, the first side slotted filter screen 204, the second side slotted filter screen 208, center bush/wheel hub 206, the extension 80 of jacket 46 and the path that passes through housing 42 that sidewall 72 limits.So the quality body enters in the housing 42 by the inlet that the end face 102 by the scraping part 84 of inlet extension 90, first access panel 86, second access panel 88 and central seal 76 limits.Mobile in the path that the quality body limits towards the back of central seal 76 and around inner surface, the first side slotted filter screen 204, the second side slotted filter screen 208 and the center hub/spacer 206 of center hub/spacer 206 part 82 by the C shape of central seal 76 outside then.At last, the quality body is by leaving housing 42 by top surface 96, the extension 80 of jacket 46 and the assembly outlet (promptly first exporting 15) that sidewall 72 limits at the one-tenth angle of the bottom surface 104 of the scraping part 84 of central seal 76, outlet extension 92.

In use, the quality body enters housing 42 by inlet and is pushed around center hub/spacer 206.When center seal 76 and housing 42 fix in position, rotary screen assembly 200 will be as mentioned above along with 57 rotations of electric machine assembly output shaft.The pressure of quality body will promote the quality body towards the outlet that the quality body concentrates the housing 42 of assembly 40 and concentrate assembly 40 by the quality body in the piping 22.Yet, when the quality body moves through the quality body and concentrates assembly 40, the slotted filter screen 204,208 of the both sides of quality body will be with restriction such as the U.S. Patent No. 4,534 that is caused by first and/or second valve as described below, removes the part of liquid from the quality body described in 868.When slotted filter screen 204,208 when the quality body is removed liquid a part of, liquid falls by a pair of regional 180 (referring to Fig. 6 A) between each of rotary screen assembly 200 and interior clamshell 48 and jacket 46.Liquid leaves housing 42 by filtrate drain 62 then.So the liquid part will flow through slotted filter screen 204,208, and flow through the filtrate drain 62,62 ' of jacket 46 and interior clamshell 48 downwards respectively.When in the circular path of quality body in housing 42 when mobile, the scraping tip 100 of the scraping part 84 of central seal 76 will scrape the quality body and the quality body be moved to the outlet of housing 42 from center hub/spacer 206.When the quality body towards first outlet 15 of housing 42 when moving, the quality body will comprise the solid portion of the removed quality body of the liquid of certain percentage.Because quality body discharge area is outside convergent rather than straight as mentioned above, therefore can control the quality body better, and will reduce the bridge joint of quality body and/or bonding.

As mentioned above, the pressure of the liquid component of certain percentage in second valve, 19 controls, second outlet 17.So second valve 19 will make the liquid in the zone 180 remain on certain pressure.By the pressure (by the pressure in second outlet 17) of liquid in the control area 180, second valve 19 can be controlled from the amount of the liquid of quality body removal.For example, if the pressure of the quality body in the second piping section 26 equals the pressure of liquid in the zone 180,,, second valve 19 will not be removed from the quality body owing to having liquid when the quality body passes when concentrating assembly 40.Yet in case second valve 19 is opened, second valve 19 reduces second fluid pressure that exports in 17 with allowing, and reduces the fluid pressure in the zone 180 thus.Second valve 19 preferably can be regulated continuously to allow to regulate continuously the pressure in second outlet 17, the pressure in the continuous thus control band 180.Second valve 19 can be a pinch valve, for example the pinch valve of being sold by the Red Valve Company company in Pennsylvania Pittsburgh city with the title of Type A Pinch Valve.Second valve 19 can comprise a plurality of valves, and each valve is directly connected to each drainage tube 62, makes that the pressure in each zone 180 can be controlled.Yet second valve 19 can only be connected to each housing 42 with the pressure in the zone 180 of control in the single housing 42 or be connected to each quality body and concentrate the pressure of assembly 40 with the zone 180 that is used for controlling whole assembly 40.Further can expect to use and be used for raising any valve or any system of pressure of zone 180 liquid.So therefore second valve 19 can be conditioned so that in the zone 180 pressure of liquid remain on any level, in the zone 180 in the pressure of liquid and the concentrated assembly 40 the more big-difference between the pressure of quality body allow the liquid of bigger percentage to be removed from the quality body.

In addition, as mentioned above, the pressure of the quality body of housing 42 is left in 35 controls of first valve, controls thus from the percentage of the liquid component of quality body removal.So first valve 35 will make the quality body that leaves first outlet 15 remain on certain pressure.By controlling the pressure of quality body in first outlet 15, first valve 35 can be controlled from the amount of the liquid of quality body removal.For example, if the pressure of quality body equals the pressure of quality body in first outlet 15 in the second piping section 26,,, first valve 35 will not be removed from the quality body owing to having liquid when the quality body passes when concentrating assembly 40.Yet in case first valve 35 cuts out, first valve 35 will force the pressure that concentrates quality body in the assembly 40 to increase, and the pressure that will concentrate quality body in the assembly 40 thus is elevated on the liquid in the zone 180.First valve 35 preferably can be regulated continuously, allows to regulate continuously the pressure in first outlet 15 thus.First valve 15 is cone valve preferably.Yet, can expect to use to be used for raising any valve or any system of pressure of housing 42 quality bodies.So regulate first valve 15 so that concentrate on the pressure that the pressure of quality body in the assembly 40 is elevated to liquid in the zone 180, the more big-difference that concentrates between the pressure of liquid in the pressure of quality body in the assembly 40 and the zone 180 allows the liquid of bigger percentage to be removed from the quality body.So, can control the density of leaving the quality body that concentrates assembly 40.

As shown in fig. 1, device 10 preferably includes the pressure that is used for the sensing second piping section 26 quality bodies, is used for the pressure of sensing first outlet 15 and/or is used at least one pressure sensor 23 of the pressure of sensing second outlet 17.Described at least one pressure sensor 23 is measured the pressure of quality body in the pressure of quality body in second piping section 26 and the pressure differential between the pressure in second outlet 17 and/or the second piping section 26 and the pressure differential between the pressure in first outlet 15.Described at least one pressure sensor 23 sends to quotient relay 25 with this information then.The information that quotient relay 25 receives from described at least one pressure sensor 23, and optionally control first valve 35 and/or second valve 19 thus.In the embodiment shown, quotient relay 25 uses air pressure from air pressure source 33 to control first valve 35 and/or second valve 19.So quotient relay 25 control first valve 35 and/or second valves 19 are controlled the pressure in first outlet, 15 and/or second outlet 17 thus respectively.In addition, by controlling the pressure of first outlet, 15 and/or second outlet in 17, device 10 can concentrate the amount of the liquid component that the quality body the assembly 40 removes from the quality body as following control described in more detail.Yet, can expect to use any control system control and monitor that the pressure in the second piping section 26, first outlet, 15 and/or second outlet 17 concentrates the percentage of the liquid component that the quality body the assembly 40 removes with control from the quality body.Thickened mass can be carried out further the concentrating of quality body (in Fig. 1 7) by being inserted again or be used (in Fig. 1 9) as thickened mass under end-state in another housing 42 then.

In the example shown, the quality body concentrates several parts that assembly 40 comprises the inside, the first side slotted filter screen 204 and the second side slotted filter screen 208 that are used to clean housing 42.At first, the scraping part 84 of central seal 76 comprises the side 106 upwardly extending a plurality of inlet scrapings 140 (referring to Figure 12) from scraping part 84.When the first side slotted filter screen 204 and the second side slotted filter screen, 208 rotation process inlet scrapings 140, inlet scraping 140 is in abutting connection with the medial surface of the first side slotted filter screen 204 and the second side slotted filter screen 208, thus when their rotations through inlet during scraping 140, the medial surface of the swipe first side slotted filter screen 204 and the second side slotted filter screen 208.Secondly, the scraping part 84 of central seal 76 comprises the side 106 outward extending a plurality of quality body scrapings 142 (referring to Figure 12) from scraping part 84.When the first side slotted filter screen 204 and the second side slotted filter screen, 208 rotation process inlet scrapings 140, the medial surface of the quality body scraping 142 adjacency first side slotted filter screen 204 and the second side slotted filter screen 208, the medial surface of the first side slotted filter screen 204 and the second side slotted filter screen 208 of when their rotate the scraping part 84 of process central seal 76, swiping thus.Once more, the scraping part 84 of central seal 76 is included in a pair of flooding nozzle 144 in the side 106 of scraping part 84.Scraping part 84 comprises the aperture 146 by scraping part 84, and flushing liquor inlet 148 (referring to Figure 13) are arranged in the end face 108 of scraping part 84.As shown in Fig. 3 and 4, the water that enters water source 29 also may be directed to the flushing liquor inlet 148 in the scraping part 84, enters aperture 146 then.Water cleans the first side slotted filter screen 204 and the second side slotted filter screen 208 thus by 146 ejections from the aperture of the flooding nozzle 144 in the side 106 of scraping part 84 when their rotation process scraping parts 84 then.Can between the operating period of device 10, (promptly when the quality body is concentrated) wash and clean the first side slotted filter screen 204 and the second side slotted filter screen 208 so can expect nozzle 144.At last, can be by by lancing door 60 ', 60 water or cleaning fluid being injected interior clamshell 48 and the whole housing 42 of jacket 46 cleanings respectively as mentioned above.
