Overpressure self-washing filter

Abstract

The invention discloses an overpressure self-washing filter. According to the overpressure self-washing filter, a filtering pipe is arrayed in a filtering pot; the side wall of the filtering pot is provided with a filtering solution outlet; a feeding pump and a feeding valve are mounted on a feeding pipe at the feeding end of the filtering pot; a pressure gauge and an automatic valve are arranged on a discharging pipe at the discharging end of the filtering pot; a reflowing pipe is connected between the discharging pipe at the discharging end and the feeding pipe of a feeding pump at the feeding end; a manual adjusting valve is arranged on the reflowing pipe. The overpressure self-washing filter has the technical effects that firstly, filtering materials flow in the filtering pipe and the flowing direction and the filtering direction of the filtering materials are different; the filtering materials are not easily deposited in the inner wall of the filtering pipe and the overpressure self-washing filter has a self-washing function so as to ensure the continuous filtering function of the filtering pipe; secondly, after the materials in the filter are filtered repeatedly, the concentration is increased and the pressure is increased; the automatic valve on the discharging pipe is opened automatically to discharge the materials and the feeding valve is switched on to pump new materials into the filtering pot to be filtered.

Description

technical field [0001] The present invention relates to a filter. Background technique [0002] At present, the filters used in the food industry are all plate-type sheet filters. The filter tank is equipped with multi-layer filter sheets. The filtered matter is easy to block on the filter sheets and loses the filtering function. First, it needs to be washed frequently, which affects production; Second, the filtering effect is poor and the production efficiency is not high. Contents of the invention [0003] The purpose of the present invention is to provide an overpressure self-cleaning filter. [0004] The technical solution of the present invention is an overpressure self-cleaning filter, filter tubes are arranged in the filter tank, there is a filtrate outlet on the side wall of the filter tank, and a feed tube is installed on the feed end of the filter tank. Pump and feed valve, pressure gauge and automatic valve are installed on the discharge pipe on the discharge ...
