Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As depicted in figs. 1 and 2, dust air seal set in a kind of horizontal decanter centrifuge described in the utility model, comprise the helical axis 1 of hollow, helical axis 1 is provided with and is communicated with its inside and outside through hole 22, the outer surface of helical axis 1 is provided with the thread 2 for pusher, the feed pipe 3 of feed is provided with in helical axis 1, helical axis 1 inside is stretched in one end of feed pipe 3, the other end communicates with the external world, rotary drum 4 is arranged with outside helical axis 1, rotary drum 4 is provided with fluid hole 5 and discharge opening 6, rotary drum 4 is wrapped with case 7, a cavity is formed between rotary drum 4 and case 7, dividing plate 8 is provided with in case 7, cavity is divided into sap cavity 9 and material chamber 10 by dividing plate 8, fluid hole 5 is communicated with rotary drum 4 inside and sap cavity 9, discharge opening 6 is communicated with rotary drum 4 inside and material chamber 10, case 7 is provided with liquid outlet 11 and discharging opening 12, liquid outlet 11 is communicated with sap cavity 9 and the external world, discharging opening 12 is communicated with material chamber 10 and the external world, the two ends of helical axis 1 are connected respectively by end cap 13 with the two ends of rotary drum 4, and end cap 13 is arranged on helical axis 1 by bearing 14 rotation, rotary drum 4 is fixedly connected with end cap 13, case 7 leaves gap 15 material chamber 10 between that end edge and one of them end cap 13, this end cap 13 described is circumferentially provided with some blades 16, blade 16 is near gap 15.
The described end cap 13 near expecting chamber 10 is provided with the sealing ring 17 that monolateral cross section is L shape, blade 16 is rectangle, blade 16 is fixed on sealing ring 17 and two right-angle sides of two right-angle sides of blade 16 and L are affixed, a side of sealing ring 17 is parallel with the edge of case 7 and form passage 18 between the two, and blade 16 is positioned at passage 18.Admission passage 18 after outside air is come in from gap 15 like this, because passage 18 is narrower, such air-flow Relatively centralized, logistics just more can not be blown out from passage 18 and gap 15.
Described blade 16 is inclined on sealing ring 17, and such blade 16 can drive stronger being entered by gap 15 of the air outside case to expect chamber 10 when rotating.
Described case 7 is outside equipped with drive unit, stretches out case 7 near one end of the end cap 13 in material chamber 10 and is connected with the drive unit outside case 7.Described drive unit is motor 19, the driving pulley 20 be arranged on motor 19 output shaft, is arranged on the driven pulley 21 that end cap 13 stretches out that end of case, is connected between driving pulley 20 and driven pulley 21 by belt.
The course of work of the dust air seal set in the utility model horizontal decanter centrifuge is: as shown in Figure 1, material enters in helical axis 1 from feed pipe 3, then enter between helical axis 1 and rotary drum from through hole 22, helical axis 1 rotates, material moves right under the effect of thread 2, rotary drum 4 rotates simultaneously, the fluid hole 5 of moisture in material on rotary drum 4 enters sap cavity 9, then flow out from liquid outlet 11, and continued to move right by the solid material after drying, and enter material chamber 10 from discharge opening 6, flow out from discharging opening 12 subsequently and collected by collecting box, because the solid material after drying flies away in material chamber 10 after enter material chamber 10 from discharge opening 6, because end cap 13 can rotate together along with rotary drum 4 under the driving of motor 19, therefore blade 16 also can rotate and form air-flow, a small amount of air in the external world is introduced in material chamber 10 by gap 15, due to the existence of air-flow, the solid material flown away just can not waft to the external world from gap 15, this ensure that the safety of production, avoid material contaminated environment, especially the Separation of Solid and Liquid of dust-like and cotton-wool class material is suitable for, the Separation of Solid and Liquid of inflammable and explosive material can also be used for simultaneously, its effect is fairly obvious, material can be avoided to overflow and to produce danger.
