Abstract

The invention relates to a self-cleaning filter, wherein a filter element is mounted on the lower seal cover of a filter cylinder in a pressed manner through a filter element gland, a water inlet pipe is arranged on the side wall of the upper part of the filter element of the filter cylinder, a water outlet pipe is arranged on the side wall of the filter cylinder, which corresponds to the filter element, the top of the filter cylinder is connected with a speed reducer seat in a supporting manner through an upper flange and a lower flange, a speed reducer with a motor is arranged on the speed reducer seat, the speed reducer is connected with one end of a rotating shaft, the other end of the rotating shaft is connected to a wire brush, and the wire brush is arranged inside the filter element and is in a contact state with the inner wall of the filter element in a rotating manner; and a foot tube is arranged at the bottom of the filter cylinder and supports the lower seal cover, and a pollution discharge port communicated with the interior of the filter element is arranged on the foot tube. The wire brush is arranged on the inner wall of the filter element of the filter, and the wire brush is driven by a motor to rotate in a way of being clung to the inner wall of the filter element, so as to achieve self-cleaning of the filter element. The filter has a simple structure, has an automatic cleaning function and high filter efficiency, and is excellent in filter effect, convenient to maintain, low in cost and long in service life.

Description

Self-cleaning filter

Technical field

The present invention relates to a kind of filter, is a kind of filter that has self-cleaning function specifically.

Background technology

Water resources problems not merely is the challenge that has 1,300,000,000 populations China just to face, and we must be appreciated that this crisis and take action; With regard to its importance, the water industry will be " a next oil industry ".To drink water purifying and recycling of water resource-desalinization and regeneration effluent recycle conversion, its core is the application of filtering technique from waste water control in water treatment.The conventional filter filter core is fixed in the filter, and the long-term back filter effect that uses reduces, and can't change, and has a strong impact on filter effect; The filter of existing removable cartridge structure, but filter dismounting flushing operation is loaded down with trivial details, wastes time and energy, and operating efficiency is filtered in influence.

Summary of the invention

In order to solve deficiency of the prior art, the purpose of this invention is to provide a kind of simple in structurely, good filtration effect has automatic cleaning function, and filter efficiency is high, and is easy to maintenance, the self-cleaning filter of long service life.

For achieving the above object, the technical scheme that the present invention adopts is: a kind of self-cleaning filter comprises cartridge filter and filter core; Filter core press-fits in capping under the cartridge filter through the filter core gland; Cartridge filter filter core upper portion side wall is provided with water inlet pipe, and the cartridge filter sidewall corresponding with filter core is provided with outlet pipe, it is characterized in that: said cartridge filter top engages supporting one reducer pedestal through upper and lower flange; Reducer pedestal is provided with the reductor of a translator; Reductor connects rotating shaft one end, and the rotating shaft other end connects wire brush, and wire brush is arranged at filter core inside and is and filter core inwall rotation contact condition; Said cartridge filter bottom is provided with the pin tube, and the pin tube supports capping down, and the pin tube is provided with and is communicated with the inner sewage draining exit of filter core.

Further, said sewage draining exit is provided with magnetic valve.

Again further, said rotating shaft is through the follower hermetically passing and be supported on the upper and lower flange.

In filter when work,, water inlet pipe is intake in cartridge filter, and it is inner that the water body that contains foreign material gets into filter core, through filter core filters from inside to outside after from the outlet pipe discharge, foreign material by filter element filtering at the filter core inwall; But by in the filter core or the work of outlet pipe upward pressure automatic control motor; Motor rotates through reductor driven rotary axle; Rotating shaft drives wire brush in the rotation of filter core inner close fitting filter core inwall, and with the foreign material brush that is piled up in the filter core inwall down, the solenoid control sewage draining exit is opened simultaneously; Foreign material under the wire brush brush are discharged through sewage draining exit, and filter element is realized automated cleaning.

The present invention is provided with wire brush at the filter element inwall, is close to the automatically cleaning that the rotation of filter core inwall realizes filter core through the motor-driven wire brush, and this filtration device structure is simple; Have automatic cleaning function, filter efficiency is high, good filtration effect; Easy to maintenance, use cost is low, the life-span is long.
