A kind of vertical axial flow pump type walnut shell filter and filtering method thereof

Abstract

The invention relates to a vertical axial-flow pump walnut shell filter and a filtering method. The filter comprises a tank body, annular supports, a water input pipe, a water output pipe, a discharge pipe and a multistage filter layer. The tank body is fixedly installed on a pedestal vertically The water input pipe is installed at the upper part of the tank body in a communicated manner. A water input pipe electric butterfly valve is installed on the water input pipe. The bottom of the tank body is communicated with the water output pipe. The water output pipe is equipped with a water output valve. The bottom of the tank body is communicated with the discharge pipe. The discharge pipe is equipped with a discharge valve. A plurality of layers of annular supports are fixedly installed on the inner wall of the tank body at upper and lower intervals. The annular supports are used for supporting the multistage filter layer. A water absorption chamber is fixedly installed at the central part in the tank body vertically and coaxially. The water absorption chamber has a cylindrical structure with openings at the upper and lower ends. A transmission shaft is installed in the water absorption chamber vertically and coaxially. The upper end of the transmission shaft extends out from the tank body and is equipped with a motor in a driving manner. A pump impeller is installed at the lower part of the transmission shaft in the water absorption chamber coaxially. The filter is suitable for deep processing of oil-containing sewage in petroleum industry, and the processing effects are good.

Description

technical field [0001] The invention belongs to the field of filters, in particular to a vertical axial flow pump type walnut shell filter and a filtering method thereof. Background technique [0002] In petrochemical, metallurgy, offshore oil platforms and other workplaces with oily sewage, the water must be filtered and treated to meet the oilfield reinjection water requirements and the discharge standards stipulated by the environmental protection department. The existing filtering equipment has a simple structure, and the effect standards of water treatment are different, and the effect of advanced sewage treatment cannot be achieved. [0003] After searching, the following similar patent technologies were found: [0004] A vertical long-axis pump self-cleaning anti-vortex shock-absorbing filter (CN204628107U), which includes an interface sleeve and a water-absorbing sleeve arranged at its lower end and a filter screen arranged inside, and a deflector is arranged in the...
