Backwater flushing type filter device

Abstract

The invention discloses a reverse water pressure flushing type filter device, which comprises a filter seat arranged in the water outlet of the pool, a filter net is arranged in the filter seat, a filter hole and a spare filter hole are arranged on the filter seat, and the filter net is fixed on the In the filter hole, a spare filter screen is fixed in the spare filter hole, and a diversion baffle is arranged on the front of the filter seat, and one end of the diversion baffle is connected to the filter seat between the filter hole and the spare filter hole through a rotating shaft Above, a water pump is fixed on the front of the bottom wall of the filter seat, and a backwash nozzle connected to the water pump is provided on the back of the filter seat. The structure setting of the present invention is reasonable, and it completes the switching between the filter screen and the standby filter screen through the guide baffle when it is in use, but starts the water pump, and backwashes the filter screen through the backwash nozzle, thereby realizing the filter screen. The cleaning operation of the net is simple and fast, and can effectively ensure the filtering effect of the filter net. It has good stability in use, strong applicability, and good practicability.

Description

technical field [0001] The invention belongs to the technical field of filters, and in particular relates to a backwater pressure flushing filter device. Background technique [0002] In water storage and drainage equipment, filter devices are generally used to filter some slag in the reservoir to make the discharged water clean. However, when used for a long time, there will be more dust and debris on the filter, thus It will affect the filtering effect of the filter, and the filter needs to be cleaned or replaced in advance. It is not only troublesome to operate, but also easy to damage the filtering device, thereby limiting the applicability and practicability. Contents of the invention [0003] The object of the present invention is to provide a backwater pressure flushing filter device with reasonable structure and good stability. [0004] The technical solution to achieve the purpose of the present invention is a backwater pressure flushing type filter device, which...
