Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a two box little throughput valveless filter equipment, including water distribution box 1, water distribution box 1's bottom fixedly connected with produces hydroecium 2 and filter chamber 3, the inside of filter chamber 3 is provided with siphon equipment 4, the opposite face of producing hydroecium 2 and filter chamber 3 is provided with communicating pipe 5, water distribution box 1's bottom fixedly connected with oral siphon 6, produce hydroecium 2's bottom fixedly connected with circulating pipe 7, circulating pipe 7 keeps away from the one end of producing hydroecium 2 and water distribution box 1's bottom fixed connection, the top fixedly connected with drain pipe 8 of filter chamber 3, siphon equipment 4's bottom is equipped with loudspeaker form guide plate, the guide plate below is equipped with quartzy sand filter layer and quartzy sand bed course in proper order, quartzy sand bed course sets up on the filter plate.

In the embodiment, when the device is used, raw water enters the water distribution box 1 through the water inlet pipe, is filtered from top to bottom through the filtering chamber 3, clear water is injected into the water production chamber 2 from the communicating pipe 5 below the two chambers, when the water in the water production chamber 2 rises to a designed position, because the filtering layer continuously intercepts suspended matters in the water body, the resistance of the filtering layer is gradually increased, so that the water level of the siphon rises, when the water level of the water production chamber 2 rises to the designed position, the water enters the air extractor in the siphon auxiliary pipe, because the air in the siphon is taken away under the action of water power, negative pressure is formed, the water in the water production chamber 2 flows back to enter a backwashing process of the filtering chamber 3 through the communicating pipe 5 in the middle of the two chambers, so the backwashing process is fast in speed and high in efficiency, through the water production chamber 2, the raw water can enter a stage filtering process of the water production chamber 2 through the communicating pipe 5 from the filtering chamber 3, in addition, a siphon device 4 is arranged outside the top of the tank body, the siphon device 4 penetrates through the top of the filter chamber 3 and extends into the filter chamber 3, a horn-shaped guide plate is arranged at the bottom of the filter chamber 3, a quartz sand filter layer and a quartz sand cushion layer are sequentially arranged below the guide plate, the back washing process can be manually destroyed when the quartz sand cushion layer is arranged on the filter plate, and can also be manually started, so the back washing process has high speed and efficiency, and the filter material is uniformly washed and can be widely used for filtering water in various environments, finally, the siphon device 4 is arranged, and is mainly used for lowering the water surface in the water production chamber 2, enabling the clear water in the water production chamber 2 to enter the filter chamber 3 which is being back washed and participate in back washing to ensure enough washing time, and enabling forced back washing when the water surface in the siphon ascending pipe does not reach the highest water surface in the back washing front pipe, the pressure is intake, reach the purpose that forces to wash, because the filtering layer constantly holds the suspended solid in the holding-back water body, the resistance of filtering layer increases gradually for the siphon water level rises, get into the air exhaust device in the siphon auxiliary pipe when the water level rises to the design position, because hydraulic action takes away the air in the siphon, form the negative pressure, when the negative pressure reaches the design value, take place siphonage promptly, at this moment the water in the water tank forms the refluence, constantly wash from bottom to top below the filtering layer, the filtering layer obtains an effect of "regeneration".

Specifically, the top end of the siphon device 4 penetrates the outside of the filter chamber 3, and the cross-sectional shape of the siphon device 4 in plan view is circular.

In this embodiment, by providing the siphon device 4, when the impurities in the filter material layer are accumulated to a certain degree, the back washing is automatically induced, and when the washing is completed, the siphon is automatically broken to continue the filtration.

Specifically, the number of the communicating pipes 5 is three, and the three communicating pipes 5 are located on the inner sides of the water producing chamber 2 and the filtering chamber 3.

In the embodiment, the three communicating pipes 5 are arranged, so that the backwashing process is high in speed and efficiency, the filter material is uniformly washed, and the filter material can be widely used for filtering water in various environments.

Specifically, top covers are arranged on the tops of the water distribution box 1, the water production chamber 2 and the filtering chamber 3, and the top cover is rectangular in section.

In this embodiment, through being provided with the top cap, can improve the sanitary protection condition to can open-air setting, it is little to compare the dead weight with the reinforced concrete filtering pond, and area is little.
