Problems solved by technology

[0003] In order to overcome the existing pressure difference filter, the particles and suspended solids in the water are subjected to the pressure of the water flow for a long time, and they stay in the stainless steel filter mesh to cause impaction, block the stainless steel filter mesh, reduce the filtering effect, and mechanical cleaning is difficult. The invention provides an automatic filter with a swirl device, the automatic filter with a swirl device can not only reduce the phenomenon that particles and suspended matter in water block the stainless steel filter net

Abstract

The invention discloses an automatic filter with a rotational flow device, belongs to water treatment equipment, and in particular relates to filters for treating circulating water. The automatic filter with the rotational flow device comprises a barrel body, a water inlet, a water outlet, a filter screen and a blowdown pipe and is characterized in that the water inlet and the water outlet are respectively formed in two ends of the horizontal barrel through tapered transitional areas, and the filter screen is installed in the barrel body through a filter screen fixing plate; a water inlet guide plate and a water outlet guide plate which are composed of three uniformly distributed blades are respectively arranged in the tapered transitional areas of the two ends of the barrel body, and the guide plates are fixed on the tapered transitional areas through support frames. The automatic filter with the rotational flow device has the beneficial effects that the filter is provided with the rotational flow device, therefore particle impurities and suspended solids in water are hovered and deposited outside the filter screen of the inner wall of the barrel body under the action of centrifugal force and can be discharged from a discharge outlet along the circumferential tangent line of the barrel wall, the blocking of the stainless steel filter screen is reduced, the filtering efficiency of the filter screen is improved, and the service life of equipment is prolonged.

Description

technical field [0001] The invention belongs to water treatment equipment, in particular to a filter used for treating circulating water. Background technique [0002] In the treatment of circulating water, differential pressure filters and backwash filters are usually used. During the operation of these filters, the water flow containing impurities directly hits the filter screen. The particles and suspended solids in the water are under the pressure of the water flow for a long time and stay on the stainless steel filter screen. Impaction occurs in the hole, which blocks the stainless steel filter screen, reduces the filtering effect, and is difficult to clean mechanically. Contents of the invention [0003] In order to overcome the existing pressure difference filter, the particles and suspended solids in the water are subjected to the pressure of the water flow for a long time, and they stay in the stainless steel filter mesh to cause impaction, block the stainless ste...
