Abstract

The utility model relates to a self-cleaning filter. A filtering core is pressed on a lower sealing cover of a filtering barrel through a filtering core pressing cover, a water inlet pipe is disposed above the filtering core and on the side wall of the upper portion of the filtering core of the filtering barrel, a water outlet pipe is arranged on the side wall of the filtering barrel, which corresponds to the filtering core, the top of the filtering barrel is connected through an upper flange and a lower flange and is used for supporting a reducing stand, a reducer with a motor is arranged on the reducing stand, the reducer is connected to one end of a rotary shaft, the other end of the rotary shaft is connected to a wire brush, the wire brush is arranged inside the filtering core and is in rotary contact with the inner wall of the filtering core, a foot barrel is arranged at the bottom of the filtering barrel, the lower sealing cover is supported by the foot barrel, and the foot barrel is provided with a drain outlet which is communicated with the inside of the filtering core. The steel brush is arranged on the inner wall of the filtering core of the filter, the motor drives the wire brush to be tightly attached to the inner wall of the filtering core to rotate, the self-cleaning of the filtering core is achieved, and the filter is simple in structure, high in filtering efficiency, good in filtering effect, convenient to maintain, low in use cost and long in service life and has a self-cleaning function.

Description

Self-cleaning filter

Technical field

The utility model relates to a kind of filter, is a kind of filter with 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 " next Petroleum Industry ".Water treatment is from waste water control to drink water purifying and recycling of water resource-desalinization and the recycling conversion of regeneration effluent, and its core is the application of filtering technique.The conventional filter filter core is fixed in the filter, and filter effect reduces after long-term the use, can't change, and has a strong impact on filter effect; The filter of existing removable cartridge structure, but the dismounting filter flushing operation is loaded down with trivial details, wastes time and energy, and operating efficiency is filtered in impact.

Summary of the invention

In order to solve deficiency of the prior art, the purpose of this utility model provides a kind of simple in structure, and 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 solution adopted in the utility model is: a kind of self-cleaning filter, comprise cartridge filter and filter core, filter core press-fits in the cartridge filter lower seal through the filter core gland and covers, cartridge filter filter core upper portion side wall is provided with water inlet pipe, the cartridge filter sidewall corresponding with filter core is provided with outlet pipe, it is characterized in that: described cartridge filter top is through upper, lower flange engages supporting one reducer pedestal, reducer pedestal is provided with the reductor of a translator, reductor connects rotating shaft one end, the rotating shaft other end connects wire brush, and wire brush is arranged at filter core inside and is and filter core inwall rotating contact state; Described cartridge filter bottom is provided with the pin cylinder, and the pin cylinder supports lower capping, and the pin cylinder is provided with the sewage draining exit that is communicated with filter core inside.

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

Again further, described 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 the water body that contains foreign material enters filter core inside, after filter core filters from inside to outside, discharge from outlet pipe, 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 and rotates at filter core inner close fitting filter core inwall, the foreign material brush that is piled up in the filter core inwall is lower, the solenoid control sewage draining exit is opened simultaneously, foreign material under the wire brush brush are discharged by sewage draining exit, and filter element is realized automated cleaning.

The utility model arranges wire brush at the filter element inwall, is close to the automatically cleaning that the rotation of filter core inwall realizes filter core by 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.
