In order to solve the above problems, the utility model provides a sewage filtering device with positive high density filtration and reverse automatically cleaning. The filter tower is characterized by comprising a filter tower, nineteen filter sticks are uniformly distributed in the filter tower, the filter sticks are connected and fixed in a filter basket and can be lifted out and replaced together, the outer wall of the bottom of the filter tower is connected with a water inlet, the outer wall of the top of the filter tower is connected with a water outlet, and the outer wall of a tower cover of the filter tower is provided with an air inlet.

Preferably, the sewage filtering device with the forward high-density filtering function and the reverse self-cleaning function is provided with 19 filter rods.

Preferably, in the sewage filtering apparatus with forward high-density filtration and reverse self-cleaning, the length of the filter stick is set to be 800mm.

Preferably, in the sewage filtering apparatus with forward high-density filtering and reverse self-cleaning functions, the filter basket and the pressure plate are made of 304 stainless steel.

Compared with the prior art, the beneficial effects of the utility model are that: through the high-density filter stick, tiny rubbish in the dirty liquid is blocked outside the filter stick, and clean liquid flows into the upper end of the tank body through the hollow pipeline in the filter stick and flows out of the filter tower, so that the dirty liquid filtering function is achieved. When closing inlet and liquid outlet, aerify the jar body through the air inlet, when jar body reaches certain pressure, open the inlet, rubbish is taken out from the inlet by its high intensity air current, reaches the anti-abluent purpose for jar internal cleaning that reaches. Two handles on the clamp plate and four screws that clamp plate and filter basket are fixed can wholly propose all filter rods, quick replacement and maintenance filter core to conveniently wash jar body bottom residual rubbish. The backwash flow from top to bottom of the entire system ensures thorough and efficient cleaning of the filter cartridge.

To sum up, the utility model has the characteristics of simple structure, reasonable in design, the running cost is low.

Detailed Description

Examples

A sewage filtering device with forward high-density filtering and reverse self-cleaning functions is shown in figures 1 to 4 and comprises a filtering tower 1

A filter basket 7 is fixed on the inner wall of the filter tower 14, filter sticks 13 are uniformly distributed and fixed in the filter basket 7, the outer wall of the bottom of the filter tower 14 is communicated with a water inlet 4, the water outlet 5 is arranged at the bottom end, the outer wall of the top is communicated with a water outlet 2, and an air inlet 3 is arranged on the outer wall of a tower cover at the top of the filter tower 14. The inner wall of the filter tower 14 is hermetically welded with a filter tower mounting ring 1. The upper end of the filter tower mounting ring 1 is fixed with a filter basket 15.
