Abstract
The utility model discloses a tubular sand filtration systems that flow back more belongs to sewage treatment device technical field. It includes washed -out sand ware urceolus, washed -out sand ware urceolus internal fixation sets up a cone, a plurality of washed -out sand return of waste water pipes of fixed mounting in the cone, a cone lower extreme fixed mounting maze, the washed -out sand return of waste water pipe of fixed mounting more than three in the cone. Compared with the prior art, the beneficial effects of the utility model are that: through the design of breaking the normal procedure, increase waste water overflow pipe quantity, make the return of waste water effect and go out the water effect better to having improved the shock resistance of sand filtration system when the water yield increases suddenly, having reduced the pollution, it is good to have guaranteed to cross drainage quality of water.
Description
Technical field
The utility model belongs to technical field of sewage treatment equipment, is specifically related to a kind of many backflow tubular type Sand Filtration Systems.
Background technology
Continuous Flow sand filter, is called for short sand filtration apparatus, is that municipal sewage plant carries out advanced treatment of wastewater, reaches the important sewage disposal device of country-level emission standard A.Be filled with quartz sand in sand filtration apparatus for filter sewage, quartz sand is called for short filtrate again.Sand filtration apparatus makes filtrate circulate based on air lift principle, the mixture of the dirty sand bottom husky pond and water is passed through central tube upwardly to the upper end of airlift pump by gas lift, gas is discharged by the steam vent being arranged on the current stabilization cover of airlift pump upper end, dirty sand and the mixture of water fall into be washed in husky device, dirty sand, after the cleaning of washing husky device, falls into pond again under gravity; Addle after washed-out sand is back to front end processes through washing the washed-out sand waste pipe arranged in husky device.At present, the washed-out sand waste pipe of domestic and international sand filtration apparatus is all be symmetrical set two, like this will when the sand filtration process water yield increases suddenly return of waste water anxious, and then cause effluent quality not up to standard.
Utility model content
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of reflowing result, outlet effect better, many backflows tubular type Sand Filtration System that shock resistance is strong.
The utility model solves the technical scheme that its technical problem adopts: a kind of many backflow tubular type Sand Filtration Systems, comprise sand-washing device urceolus, it is characterized in that: described sand-washing device urceolus internal fixtion arranges a cone, vertical fixed installation some washed-out sand return of waste water pipes in described cone, described cone lower end fixedly mounts a labyrinth.
Preferably, described cone fixedly mounts the washed-out sand return of waste water pipe of more than three.
Compared with prior art, the beneficial effects of the utility model are: by design of breaking the normal procedure, increase washed-out sand return of waste water pipe (more than three), make return of waste water effect and outlet effect better, and improve the impact resistance of Sand Filtration System when the water yield increases suddenly, reduce pollution, ensure that filtered water water quality is excellent.
Accompanying drawing explanation
Fig. 1 is the main TV structure sectional view of the utility model embodiment.
Be labeled as in figure:
1, sand-washing device urceolus; 2, cone; 3, washed-out sand return of waste water pipe; 4, labyrinth.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described further.
Embodiment
As shown in Figure 1, a kind of many backflow tubular type Sand Filtration Systems, comprise sand-washing device urceolus 1, sand-washing device urceolus 1 internal fixtion arranges cone 2, cone 2 fixedly mounts the washed-out sand return of waste water pipe 3 of more than three, fixed installation labyrinth, cone 2 lower end 4.
Utility model works principle and the course of work as follows:
As shown in Figure 1, carry the mixture of dirty sand that sand pump promotes bottom sand filter and water, because sand water proportion is different, therefore under gravity, sand is by the layer of sand that falls back through labyrinth 4 after sand-washing device urceolus 1 and centrum 2, when labyrinth 4, quartz sand is cleaned, and washed-out sand addle is back to sewage disposal initiating terminal from washed-out sand return of waste water pipe 3.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
Claims (2)
1. reflux a tubular type Sand Filtration System more, comprises sand-washing device urceolus, it is characterized in that: described sand-washing device urceolus internal fixtion arranges a cone, and vertical fixed installation some washed-out sand return of waste water pipes in described cone, described cone lower end fixedly mounts a labyrinth.
2. many backflow tubular type Sand Filtration Systems according to claim 1, is characterized in that: the washed-out sand return of waste water pipe described cone fixedly mounting more than three.
