Embodiment Construction

[0018] The present invention is further described below in conjunction with accompanying drawing.

[0019] refer to figure 1 , The pressure dynamic sand filter is composed of a sand filter tank body 6, a sand distribution valve, a sand water separator 2, a bypass pipe 4, a sand delivery device 1, a sand delivery pipe 7 and a sand washing device 11. The sand filter tank body 6 is composed of a sand filter lower tank body and a sand filter upper head body, and the sand filter lower tank body and the sand filter upper head body are connected together by a pair of tank body flanges. A water inlet 5, a water outlet 8 and an exhaust port 9 are arranged on the sand filter tank body 6, and an overflow port 12 is arranged on the sand washer 11. The pressure type dynamic sand filter adopts two sand matching valves, one is the sand outlet opening sand matching valve 3 located at the lower end of the lower tank body of the sand filter, and the other is the sand falling outlet sand matchi...

Abstract

The present invention provides a pressure type dynamic sand filter. The invention relates to a sand filter applied for liquid filtering, and especially to a pressure type dynamic sand filter which can continuously wash the filter material. The aim of the invention is to overcome a defect that the common pressure type sand filter can not operate continuously, and provide the pressure type dynamic sand filter which can clean the filter material and operate continuously. The invention is mainly characterized in that the pressure type dynamic sand filter is composed of a sand filter tank body, a sand distribution valve, a sand-water separator, a bypass pipe, a sand conveyor, a sand conveying pipe and a sand washer. The sand filter tank body is internally installed with a water distribution ring, a flow guiding sand cone, a sand outlet filter element, a water outlet filter element, a sand dropping pipe and a sand distribution cone. When the pressure type dynamic sand filter operates normally, the raw water passes through a water inlet, the water distribution ring and the filter material layer, and is discharged from the water outlet filter element and the water outlet after filtering. Simultaneously the filter material is washed continuously through the sand distribution valve, the sand conveyor, the sand conveying pipe and the sand washer, and then drops into the sand filter tank body and forms a circulation.

Description

technical field [0001] The invention relates to a pressure type dynamic sand filter, which relates to a sand filter used in liquid filtration, in particular to a pressure type dynamic sand filter which can continuously clean the filter material. Background technique [0002] Ordinary pressure sand filters cannot work continuously. After working for a period of time, the filter material is blocked by suspended solids in the raw water, and it needs to stop working and reverse wash the filter material with clean water. Therefore, when the system needs continuous water supply, it is necessary to use two ordinary pressure sand filters to form a method of one for use and one for standby. Therefore, the complexity of equipment control, equipment investment cost and equipment footprint are increased. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that common pressure type sand filters cannot work continuously, and provide a press...
