detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

A kind of gravity integrated water purifier embodiment as shown in Figure 1, Figure 2 and Figure 3, comprises water inlet pipe 1, folded plate reaction tank 2, inclined tube sedimentation tank 4, collector The water tank 5, the filter tank 7, and the bottom of the inclined tube sedimentation tank 4 are provided with a sludge return device 3, and the filter tank 7 is provided with a water outlet 9. The top of the filter tank 7 is provided with a siphon device 6 for backwashing of the filter material; the filter tank 7 is provided with a clear water area, a filter area and a water collection area in sequence from top to bottom, and the water collection tank 5 is connected to the filter area through an elbow; An active filter bed 8 is provided, and a filter material is arranged on the active filter bed 8 . The active filter bed 8 includes a bracket and a filter plate formed by a plurality of filter units 81. The filter unit 81 includes a shell 82, and the shell 82 forms a number of equal filter tanks 83 through its internal transverse wall and vertical wall. 83 is provided with some strip water filter holes 84. The siphon device 6 includes a siphon ascending pipe, a siphon descending pipe and a siphon auxiliary pipe connected in sequence; a siphon destroying bucket pipe is connected to the bottom of the siphon auxiliary pipe; the end of the siphon ascending pipe extends into the water tank. The filter material is arranged on the water filter plate, which includes a pebble layer, quartz sand, anthracite layer and active carbon layer arranged sequentially from bottom to top. The inclined tube sedimentation tank 4 is composed of hexagonal honeycomb inclined tubes. The hexagonal honeycomb inclined tubes are conducive to the decline of sediment and the rise of clarified water, and are not prone to clogging. At the same time, they have good integrity and high compressive strength. , which is conducive to maintaining its original state in the pool for a long time.

The working process of the utility model is: during work, the raw water enters the folded plate reaction tank 2 and the inclined tube sedimentation tank 4 successively through the water inlet pipe 1. After the flocs are separated from the water, the clear water enters the filter tank 7 from the sump 5 for filtration, and the turbidity such as suspended solids in the raw water is intercepted and adsorbed on the surface of the filter material layer and in the filter material layer. Under the action of the level difference of the two liquid levels after filtering, the water collecting area enters the clear water area from bottom to top, and the qualified drinking water (industrial water) overflows from the clear water area into the water outlet 9 on the top and flows to the outlet pipe. Among them, the sludge return device 5 can generate self-priming phenomenon through the pressure difference, so that the settled sludge can be automatically siphoned and discharged. After the filter 7 runs for a certain period, due to the increase of suspended solids, the resistance of the filter tank is large, causing the water level to rise and rise to the top of the siphon device 6, that is, the automatic recoil of the siphon is formed. At this time, the water passes through the filter tank from bottom to top. Backwash the filter. At this time, due to the presence of the active filter bed 8, when the water flows through the filter water plate, some filter water tanks 83 in each filter water unit 81 will slow down and evenly distribute the water flow, and the strip-shaped filter holes in the water filter tank 83 will evenly enter the water filter. Due to the uniform water inflow, the filter material will not be washed away, the filter material can be evenly distributed, and there will be no dead angle, so the backwash water is evenly distributed. When the water level drops to the pipe opening of the siphon breaking bucket, the air enters from the opening of the siphon breaking bucket and enters the top of the inverted siphon descending pipe, so the siphon is broken, the backwashing water in the siphon device stops flowing, and the backwashing ends. So another cycle of filtering began.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in the Within the protection scope of the present utility model.
