Embodiment Construction

[0016] Such as figure 1 As shown, the drum-type rotary filter includes a drum 1 covered with a filter screen, and sprays the liquid to be filtered on the drum from above the drum, such as figure 1 As shown in the spray nozzle (not marked with the icon), because there is an impulse when spraying, the filtrate will pass through the filter and fall into the sink 4 installed on the frame 3 in an instant. The drum 1 is fixedly connected with the rotating shaft 2. The rotating shaft 2 is connected to a motor, and the motor is used to provide a power source for the filter. The rotating shaft 2 is installed and supported on the frame 3 and drives the drum 1 to rotate through the rotating shaft 2. The edge of the drum 1 has a peripheral edge extending outward, and the liquid to be filtered sprayed from above falls into a groove composed of the peripheral edge and the filter screen to form a containing space, so that the liquid will not spill to both sides. At the same time, the filte...

Abstract

The invention discloses a drum type rotary filter which comprises a drum covered by a filter screen, wherein the drum is fixedly connected with a rotating shaft; the rotating shaft is arranged on and supported against a frame; the drum is driven through the rotating shaft to rotate; and a water tank for receiving filtrate is also supported against and arranged on the frame. By using the technical scheme provided by the invention, the filter can continuously work and has the advantages of low cost, quick filtration and good effect. The preferred technical scheme is that the edge of the drum is provided with a surrounding edge which extends outwards and has the beneficial effects that the surrounding edge and the filter screen form a sunken space for accommodating filtered liquid, so that the filtered liquid does not move towards the lateral wing. Another preferred technical scheme is that a cleaning device for washing filter residue on the filter screen is arranged on the lower side of the water tank and has the beneficial effects that the filter residue is completely separated from the filter screen and the filter screen can realize cycle operation.

Description

Technical field [0001] The invention relates to the technical field of filtering liquid containing fine particles and sundries, in particular to a filter capable of continuous operation and adopting a rotating drum to filter liquid. Background technique [0002] At present, in the field of industrial production, especially in the field of medical filtration, people often use cloth bag-type filtering to contain fine particles and manually filter them, or use filter presses to filter cloth bags. This filtering method has many shortcomings. The use of manual filtering of cloth bags is labor intensive and slow in work efficiency; the use of filter press for filter press requires large energy consumption, large area of ​​machinery and equipment, and additional costs. Big. [0003] In the Chinese utility model patent document CN201592019U, a drum filter is disclosed. The technical solution adopted is that the filtrate rotates inside the drum. Due to centrifugal force, the sm...
