Problems solved by technology

The air washing mechanism in the existing backwashing equipment is generally set on the upper side of the filter layer to perform air washing, water washing or air-water mixed scrubbing on the filter layer. This backwashing method can only backwash a large amount of suspended matter. Part, a small part of suspended solids go deep into the inside of the filter layer and are difficult to wash out, resulting in a continuous decline in water treatment efficiency, which requires replacement of filter materials, and at the same time, it is easy to cause blockage of the air washing mechanism, increasing production costs and reducing production efficiency

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Such as figure 1 Shown: a gravity-type air scrubbing filter, including a pool body 1, a clear water bin 2 on the upper part of the pool body 1, and a filter bin 3 located on the lower side of the clear water bin 2. The clear water bin 2 is provided with an overflow port 4, and the filter bin 3 Connect with the external raw water pool through the water inlet pipe 5, the inlet of the water inlet pipe 5 is provided with a water inlet regulating valve 14, and the water inlet pipe 5 behind the water inlet regulating valve 14 is provided with a drainage branch pipe with a backwash drain valve 15 16. A filter layer 6 made of porcelain sand filter material is provided at the bottom of the filter chamber 3. The filter layer 6 is arranged on a porous filter plate 7, and the porous filter plate 7 is provided with evenly distributed filter caps 17. The porou...

Abstract

The invention discloses a gravity type air scrubbing filter pool which comprises a pool body (1), a clean water storehouse (2) and a filter bin (3), wherein an overflow opening (4) is formed in the clean water storehouse (2); the filter bin (3) is connected with an external raw water pool through a water feeding pipe (5); a filter layer (6) is arranged at the lower part of the filter bin (3) and is arranged on a multihole filter plate (7); an aeration coil pipe (8) is arranged on the lower side of the multihole filter plate (7) and is connected with an external air source through a compressed air interface (9) in the pool body (1); a communicating pipe (10) for communicating the clean water storehouse (2) and the filter bin (3) is arranged on the pool body (1); and a lower interface of the communicating pipe (10) is positioned on the pool body (1) on the lower side of the multihole filter plate (7). By combining air-water bottom-to-top backwashing and water top-to-bottom well washing, the gravity type air scrubbing filter pool is good in cleaning effect and low in production cost, improves the production efficiency and is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a novel filter device which combines the air scrubbing function of a valveless filter tank and a mechanical filter, specifically a filter device with the functions of air-water backwash and water forward wash Gravity air scrubbed filter. Background technique [0002] In the field of water treatment technology, after the filter has been used for a period of time, due to the continuous interception of suspended solids in the filter layer, the resistance of the filter layer increases and the turbidity of the effluent increases. Therefore, the filter layer needs to be cleaned. The air washing mechanism in the existing backwashing equipment is generally set on the upper side of the filter layer to perform air washing, water washing or air-water mixed scrubbing on the filter layer. This backwashing method can only backwash a large amount of suspended matter Part, a small part...
