Siphon type valveless filtering pool

Abstract

The invention discloses a siphon type valveless filtering pool comprising a pool body (1), a clean water tank (2), a filtering water chamber (3), a water outlet (4), a water inlet pipe (5), a filtering layer (6) and a closed pipe (7), wherein the pool body (1) is provided with a siphon pipe (8) which is communicated with an outlet end of the water inlet pipe (5); the siphon pipe (8) comprises a siphon ascending pipe (9) and a siphon descending pipe (10); the lower end and the upper end of the siphon ascending pipe (9) are respectively connected with the outlet end of the water inlet pipe (5) and the upper end of the siphon descending pipe (10); the lower end of the siphon descending pipe (10) is immersed into a water seal tank (11) located at the lower side of the pool body (1); and the lower wall of the upper end of the siphon ascending pipe (9) is provided with a siphon assisting pipe (12) and the upper wall of the top end of the siphon pipe (8) is provided with a siphon damaging pipe (13) with the lower end located at the bottom of the clean water tank (2). According to the siphon type valveless filtering pool disclosed by the invention, the backwashing speed is high, the efficiency is high and the backwashing is complete, so that the siphon type valveless filtering pool is suitable for being popularized and used.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a siphon type non-valve filter which adopts a siphon method to quickly backwash the 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. Because the efficiency of the existing backwashing equipment is not high, it can only backwash a large part of the suspended matter, and a small part of the suspended matter will go deeper into the filter layer and be difficult to wash off, resulting in a continuous decline in water treatment efficiency, thus The filter material needs to be replaced, which increases the production cost and reduces the production efficiency.
