Description
Technical Field
The utility model belongs to the technical field of the filter technique and specifically relates to a self-cleaning filter.
Background
In the prior art, for a filter, a filter screen is generally arranged in a container, and impurities in fluid passing through the filter screen are filtered by the filter screen, so that the function of cleaning the impurities is achieved. However, in actual use, in order to ensure the flow efficiency of the fluid, the proper filter mesh diameter needs to be selected. However, some fine particles with a particle size smaller than the mesh diameter exist in the fluid, but the fine particles can be accumulated on the inner wall of the filter or the filter mesh during long-time use, and can fall off during the impact of the fluid to enter the fluid, so that the filtering effect is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned technique not enough and provide a automatically cleaning filter, can in time clear up the tiny particle of gathering on filter screen or filter inner wall, avoid its long-pending save to be the large granule.
The utility model discloses a self-cleaning filter, which comprises a closed tank body, a layer of filter screen is arranged in the tank body, the filter screen separates the tank body into two independent cavities, a water inlet pipe is arranged on the side wall of the tank body corresponding to the cavity at the lower part, a water outlet pipe is arranged on the side wall of the tank body corresponding to the cavity at the upper part, a power mechanism is arranged at the top part of the tank body, a rotating shaft is connected on the power mechanism in a transmission way, the rotating shaft extends to the inside of the tank body and is positioned on the central axis of the tank body, the rotating shaft passes through the filter screen, the rotating shaft and the filter screen are sealed, a connecting frame is arranged on the rotating shaft in the cavity at the upper part, a rubber scraper attached to the side wall of the cavity at the upper part of the tank body and the upper surface of the filter screen is arranged on the connecting frame, a connecting frame is arranged on the rotating shaft in the cavity at the lower part, a rubber scraper attached to the side wall of the cavity at the lower part of the tank body and a brush attached to the lower surface of the filter screen are arranged on the connecting frame, the bottom of the tank body is provided with a discharge pipe, and the discharge pipe is provided with a control valve.
Above-mentioned scheme, the jar body is the hollow cylinder structure, and the fluid gets into the jar body from the inlet tube of below, exports from the outlet pipe behind the filter screen, and at filterable in-process, because the particle size of some granules is greater than the filter screen, so by the separation in the cavity of below. Of course, during the use of the filter, some fine particles may pass through the filter screen, but may adhere to the side wall of the filter or to the filter screen, so that the power mechanism is intermittently activated. Through setting up the rubber scraper on the epaxial link of commentaries on classics, the lateral wall and the filter screen of laminating top cavity, scrape on the top cavity lateral wall and the upper surface of filter screen and wash, rubber scraper and the brush on the epaxial link in below cavity scrape the washing respectively to the lateral wall of below cavity and the lower surface of filter screen simultaneously, when some fine particles adsorb on lateral wall and filter screen, can scrape it down, avoid it to collect on the surface and form the large granule and get into in the fluid after the filtration, cause the jam of rear pipeline etc.. And when some large-particle impurities on the filter screen are adsorbed on the lower surface of the filter screen along with the flow rate of the fluid after being filtered, the impurities can be brushed down by the brush and precipitated to the bottom under the action of gravity, and the impurities are discharged by intermittently starting the discharge valve. The above process can realize automatic cleaning of the filter to ensure the filtering effect.
The rubber scraper in the upper cavity of the filter is arranged in the following mode: the rubber scraper is at least vertically arranged and attached to the side wall, the rubber scraper is arranged at the top in the diameter direction, and the rubber scraper is arranged in the diameter direction and attached to the filter screen. The side wall of the cavity below the filter is at least provided with a vertical rubber scraper, and the lower surface of the filter screen is provided with a brush along the diameter direction. The arrangement can ensure that other parts except the bottom surface can be brushed or scraped in the rotating process of the rotating shaft, and the adhered particles of the parts are brushed down.
The bottom of the jar body is the back taper structure, locates to form the settling zone at the center of jar body bottom, the delivery pipe sets up in the settling zone within range, and the settling zone within range does not set up rubber scraper. The design of this structure, can be better with jar body cavity under the body brush down and the impurity that filters out deposits the back and concentrate together, can discharge smoothly when the follow-up control valve of being convenient for is opened.
The aperture of the filter screen is 0.05-0.2 mm. When this filter is used in atomizing system, the aperture of the atomizer that generally adopts is 0.6mm, so, the impurity more than 0.2mm is directly filtered, and even if there is the granule that is less than 0.2mm to get into when adsorbing the lateral wall behind the top cavity, also can in time be scraped down by rubber scraper to along fluid entering atomizing system, because it fails to collect and is the large granule, so can not lead to the fact the jam to atomizing nozzle completely through atomizing nozzle, ensure atomizing system's steady operation.
The utility model provides a self-cleaning filter can scrape the tiny particle that adsorbs on filter screen and lateral wall after the fluid filtration, avoids collecting and scraping and fall after being the large granule and block up follow-up system.
