Specific embodiment
A kind of horizontal screw centrifuge embodiment of the invention is described further referring to figs. 1 to Fig. 7.
A kind of horizontal screw centrifuge, including driving means 1, rotary drum 3, spiral propeller 2 and case, driving means 1 drive spiral propeller 2 to rotate, rotary drum 3 is arranged in case, rotary drum 3 is respectively arranged at two ends with the outlet of liquid phase thing and sediment outlet, spiral propeller 2 is arranged on the inside of rotary drum 3 and forms material pond between the inwall of rotary drum 3 and spiral propeller 2, during horizontal screw centrifuge works, driving means 1 can drive spiral propeller 2 to work, also have a power set in addition, power set drive rotary drum 3 to rotate, because spiral propeller 2 is provided with blade 8, therefore by the rotation of rotary drum 3, separate sediment and liquid phase thing, then by the rotation of spiral propeller 2, and then sediment is delivered to into sediment outlet, liquid phase thing is delivered to into the outlet of liquid phase thing.
And in order to make the separation of liquid phase thing and sediment more thorough，The present invention is using the rolling compaction device 4 for being provided with rolling compaction sediment layer near the side that sediment is exported in spiral propeller 2，Elastic component is provided between rolling compaction device 4 and spiral propeller 2，Rolling compaction device 4 is connected by elastic component with spiral propeller 2，Rolling device includes rolling wheel 41 and connecting rod 42，Rolling wheel 41 is provided with rotating shaft 6，Rolling wheel 41 is rotated with connecting rod 42 by rotating shaft 6 and is connected，Connecting rod 42 is connected by elastic component with spiral propeller 2，The axis of rolling wheel 41 and the diameter parallel of rotary drum 3，During spiral propeller 2 is rotated，Due to there is elastic component between connecting rod 42 and spiral propeller 2，With regard to the selection of elastic component，Present invention preferably employs tension spring 7，One end of tension spring 7 is connected with spiral propeller 2，The other end is connected with connecting rod 42，With the rotation of spiral propeller 2，Spiral propeller 2 can by connecting rod 42 towards sediment layer direction whipping，With the continuous improvement of the rotating speed of spiral propeller 2，Rolling wheel 41 can be contacted slowly with sediment，And work as after rolling wheel 41 contacts with sediment，Rolling wheel 41 occurs rolling，So as to the effect that rolling compaction is produced to sediment enables the liquid phase thing being attached on sediment to be effectively separated，And the setting of sleeve 5，Effectively certain position-limiting action can be played to the direction of motion of connecting rod 42，Connecting rod 42 is prevented due to the inclined phenomenon of the appearance of the impact of sediment.
Although sediment is when transport is to sediment exit，Extruding due to have passed through one-level level，The hardness of sediment is greatly improved，But because comparatively impact of the sediment layer near the sediment of the side of liquid phase thing is also said than relatively low，Therefore rolling wheel 41 has the embedded sediment layer the inside of sub-fraction，And in order to improve the rolling effect of rolling wheel 41，The present invention is adopted and for two seamed edges of the side wall of rolling wheel 41 to be disposed as bevel edge 411，Because rolling wheel 41 is when sediment is rolled，Spiral propeller 2 is also pushing the direction motion that sediment is exported towards sediment，Therefore by arranging bevel edge 411 on rolling wheel 41，Sediment is given bevel edge 411 power of the radial direction of the power conversion on the axial direction of rolling wheel 41，So as to increase the extruding force between rolling wheel 41 and sediment，And then reach more preferable rolling effect，And the service life of rolling wheel 41 is also relatively more long.
And due to the difference of horizontal screw centrifuge operative scenario，The thickness that sediment layer in horizontal screw centrifuge can be caused also occurs a certain degree of difference，After the lower thickness of sediment layer，If the rotating speed of spiral propeller 2 or that original speed，Occur that rolling wheel 41 diminishes with the contact area of sediment，Even rolling wheel 41 and sediment are not in the phenomenon of contact，At this time rolling wheel 41 is difficult to recur and arrives liquid phase thing effect detached with sediment，Therefore in order to solve this problem，The present invention is using the detection means 9 that the detection rotating speed of rolling wheel 41 is provided between rolling wheel 41 and connecting rod 42，Detection means 9 controls the rotating speed of driving means 1，Detection means 9 includes infrared ray sensor，Infrared ray sensor includes infrared receiving device 91 and infrared launcher 92，Infrared launcher 92 is arranged on the one end of rolling wheel 41，Infrared receiving device 91 is arranged in connecting rod 42 and infrared receiving device 91 is just to infrared launcher 92，When the velocity of rotation of rolling wheel 41 it is excessively slow，Also or rolling wheel 41 do not have rotate when，When namely rolling wheel 41 does not play the effect for rolling substantially to sediment layer，Infrared receiving device 91 receives the number of times of infrared launcher 92 that signal for sending within the unit interval and tails off，Signal is fed back to driving means 1 by infrared receiving device 91，With regard to driving means 1，Driving means 1 are preferably selected the YE3 series ultrahigh-efficiency three-phase asynchronous motors for the motor production of Anhui south by the present invention，When the rotating speed of rolling wheel 41 is excessively slow，Signal is fed back to ultrahigh-efficiency three-phase asynchronous motor by infrared receiving device 91，The rotating speed of ultrahigh-efficiency three-phase asynchronous motor increases，And then the rotating speed with dynamic spiral propeller 2 is improved，Until rolling wheel 41 normally rolls sediment.
And in order to be effectively protected infrared launcher 92 and infrared detecting device 9; the present invention is preferably respectively provided with transparent cloche 10 in connecting rod 42 and rolling wheel 41; infrared receiving device 91 and infrared launcher 92 are arranged in cloche 10; by cloche 10, infrared receiving device 91 and infrared launcher 92 can be played a very good protection.And in addition, in order to prevent some sediments from sticking to the signal that the reception infrared launcher 92 of infrared receiving device 91 is affected on glass, therefore apply in the outer surface of cloche 10 and be covered with self-cleaning coating, the nano material that the coating is adopted has extremely low surface tension, so as to powerful hydrophobic, oil rub resistance ability；The dirts such as dust greatly reduce with coating surface contact area, so as to have the automated cleaning characteristic being unsurpassed in excellence；Water is tumbled just as on lotus leaf in body surface and does not stay water mark, the time of keeping a public place clean can effectively be extended, therefore the thing of sediment etc also is difficult to stick on cloche 10, and the situation that the signal of infrared launcher 92 cannot be received so as to avoid infrared receiving device 91 occurs.
The course of work：Rotary drum 3 is first rotated，So that sediment is separated with liquid phase thing，Then driver 1 again，The rotating speed of driving means 1 slowly increases，And driving means 1 can work with dynamic spiral propeller 2，The rolling compaction device 4 being now placed on spiral propeller 2 can be moved towards the direction of sediment，Now tension spring 7 is in extended state，And because rolling wheel 41 does not also touch sediment，Therefore rolling wheel 41 is not in rotation phenomenon，The rotating speed of driving means 1 slowly increases，Until rolling wheel 41 is touched and rotation phenomenon occurs with sediment，After rolling wheel 41 is rotated，Infrared launcher 92 on rolling wheel 41 and then moves in a circle together，And the every revolution of rolling wheel 41，Infrared receiving device 91 receives the signal that infrared launcher 92 sends，So as to draw the rotating speed of rolling wheel 41，When the rotating speed of rolling wheel 41 reaches certain，Infrared receiving device 91 controls driving means 1，Driving means 1 are made to keep this rotating speed，Rolling wheel 41 can be enable to roll sediment constantly.
