Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By shown in Fig. 1 to Fig. 4, the continuous quicksand filter of a kind of multistage water distribution list bin, comprise housing 1, in described housing 1, middle part is equipped with the cloth sump 2 of annular, cloth sump 2 side is connected with water inlet pipe 9, cloth sump 2 bottom is connected with the water distributor 3 of several levels, cloth sump 2 ringwise, can uniformly in the future moisture be fitted on subordinate's water distributor, water arrives water distribution position through water distributor 3, before water arrives water distribution position, can not with filtrate joint, only reach completely after water distribution effect, water is meeting percent of pass material, realize the uniform filtering to water, largely avoid the phenomenon of short stream or filtering layer perforation.Described water distributor 3 has water distributing pore, water is by being evenly distributed in water distribution region by the perforate of bottom cloth water pipe after water distributor, water distributing pore on described bottom cloth water pipe is two rows, perforate direction is respectively downward 45 ° of left and right, uniformly at intervals, the effect that such structure can play water distribution can play again the effect of water conservancy diversion, prevents water distribution from causing the in uneven thickness of filtrate to same position continuous erosion.
Housing 1 internal fixtion on cloth sump 2 top has sand-washing device 5, and described sand-washing device 5 is 4, and one of them is positioned at housing 1 center, other 3 along the circumferential direction uniform.Described sand-washing device 5 is all connected with and carries sand device 4, and the bottom carrying sand device 4 is positioned at bottom housing 1, described sand-washing device 5 is connected with blow-off pipe 11.In described housing 1, filter bed top is provided with effluent weir 6, and effluent weir 6 is annular, be positioned at housing 1 interior periphery, effluent weir 6 be connected with outlet pipe 10, and the height of effluent weir 6 is a little less than sand-washing device 5.Be fixed with bracing frame 8 bottom housing 1, bracing frame 8 top is fixed with leads sand device 7, leads sand device and is positioned at below water distributor 3, in turbination, fixed by bracing frame 8, not with body contact.
During filtration, water enters cloth sump 2 by water inlet pipe 9, because cloth sump 2 moisture in future is fitted on subordinate's water distributor 3, arriving behind water distribution position through water distributor 3 is evenly distributed in water distribution region by the perforate of bottom cloth water pipe, after water distribution process completes, water is filtered by filtering layer, the filtering direction of water is from bottom to top, the upper strata of filtrate is progressively risen to from the bottom of filtrate, that is the bottom of filtrate is contaminated comparatively serious region, water completes after filtration through filtering layer gradually, arrive the effluent weir 6 of upper end, by outside outlet pipe 10 drain tank after effluent weir 6 overflow.
The backwash process of this device is relatively independent relative to filter process, and backwashing system and filtration system are not structurally occured simultaneously, the possibility that after can not there is filter, water is secondary polluted.Ji Shaqu is formed by leading between sand device 7 and housing 1 in the bottom of device, temporary contaminated filtrate is mainly used in this region, and filtrate is concentrated to being provided with the position carrying sand device 4, due to the gravity suffered by filtrate self, when the filtrate of Ji Shaqu is carried after sand device 4 withdraws, the filtrate on upper strata will hole left by automatic filling, thus realizes the continuous lifting of bottom filtrate, filtrate is carried after sand device 4 is promoted to sand-washing device 5, starts the cleaning process of filtrate.Filtrate is in the state of high-speed and high-density in sand device 4 putting forward, when entering in container relatively open in sand-washing device 5, just slowly loose motion state can be presented, loose condition (of surface) in fixed container is that the backwash of filtrate provides best condition, ensure that filtrate can clean thoroughly, by the kinetic energy that gas in sand-washing device 5 provides, mutual collision friction between filtrate, be affected by gravity, its direction of motion is lasting downward, and pollutant due to the effect moving direction of kinetic energy be continue upwards, finally realize the pollutant that filtrate adsorbs to be separated with filtrate, filtrate after separation constantly falls from newly forming filtering layer, pollutant then after rising to sand-washing device 5 top outside blow-off pipe 11 drain tank.
