Embodiment Construction

[0023] Examples such as Figures 1 to 3 As shown, a precision filter unloading device includes an inlet and outlet water chamber partition 1 arranged in the filter, and a water inlet chamber 101 and an outlet water chamber 102 respectively arranged on both sides of the inlet and outlet water chamber partition 1 . The door frame 2 is sealed and fixed on the partition plate 1 of the inlet and outlet water chamber, and the door body 3 that can be turned over is arranged in the door frame 2. The door shaft 4 is fixedly installed on the door body 3, and the two ends of the door shaft 4 are installed through bearings. On the inlet and outlet water separator 1, the bearing adopts self-lubricating ceramic rolling bearing. The door shaft 4 drives the door body 3 to rotate to realize the opening and closing of the door body 3 .

Abstract

The invention discloses an unloading device for a precision filter. The unloading device comprises an inlet / outlet water cavity separation board arranged in the filter and a turnable door body arranged in a door frame, wherein the door frame is fixedly arranged on the inlet / outlet water cavity separation board in a sealing manner; a door spindle is fixedly arranged on the door body; two ends of the door spindle are arranged on the inlet / outlet water cavity separation board by bearings; a buoyancy tank is also arranged in a water inlet cavity of the filter; connecting components are arranged between the buoyancy tank and the door spindle; the buoyancy tank vertically floats and drives the door spindle to rotate by the connecting components, so that opening and closing the door body are realized. According to the unloading device disclosed by the invention, automatic unloading is realized by arranging an unloading door on an opening hole of the inlet / outlet water cavity separation board without other bypass valves or electric components with the help of a water level force for overload rising of a filter cartridge; the gravity of the buoyancy tank is automatically reset and closed when the water level is reduced to be normal. The device has the advantages of good operation effect, high reliability and low cost; the problems of large occupied area and high equipment expenses of an existing precision filter, an unloading electrically operated valve cannot be opened during power outage and the like are solved.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to an automatic unloading device in a precision filter. Background technique [0002] In the fields of domestic sewage treatment, industrial wastewater treatment, etc., in order to make the effluent meet the first-class A standard, the most economical and effective way is to use a precision filter to filter the effluent of the secondary sedimentation tank or high-efficiency sedimentation tank. However, due to the fineness of the filter mesh of the precision filter, when the water quality of the incoming water deteriorates and other unexpected reasons cause the water level on the inlet side of the filter to rise, the water level difference between the inlet and outlet of the filter will increase, causing the filter to be subjected to excessive water pressure and the filter to rupture. accident trends. In order to prevent accidents, when the water inlet end of the precision ...
