Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model comprises a container 1 and a filter screen 2, wherein the container 1 is provided with a water inlet 3 arranged at the upper end of the container 1 and a water outlet 4 arranged at the lower part of the container 1, the filter screen 2 is a vertically arranged cylindrical tubular structure, the upper end of the filter screen 2 is communicated with the water inlet 3, and the container 1 is provided with a sewage outlet 5 communicated with the lower end of the filter screen 2 and a sealing door 6 for sealing the sewage outlet 5; the filter screen 2 and the container 1 are rotationally connected along the axis of the filter screen 2, the container 1 is provided with a motor 7, and the filter screen 2 and the motor 7 are in transmission connection through a speed reducing mechanism arranged on the container 1.
Preferably, the container 1 is provided with a scraper 8 which is arranged on the inner side of the filter screen 2 and rotates coaxially with the filter screen 2, the scraper 8 is in sliding contact with the inner edge surface of the filter screen 2, the scraper 8 is coaxially connected with the filter screen 2 through an overrunning bearing 9, and the scraper 8 is in transmission connection with the motor 7 through a speed reducing mechanism.
Preferably, the speed reducing mechanism is composed of a small gear 10 coaxially connected with the motor 7 and a large gear 11 coaxially connected with the filter screen 2, and the small gear 10 is meshed with the large gear 11.
Preferably, the closing door 6 is hinged to the container 1, and when the closing door 6 is opened, the filtered impurities fall down and slide down along the closing door 6, that is, the closing door 6 guides the impurities, so that the impurities can be collected conveniently.
Preferably, the water inlet 3 is connected with an electromagnetic valve, the closed door 6 is provided with an electronic lock, and the electromagnetic valve and the electronic lock are controlled by a control chip to realize the orderly water inlet and sewage discharge.
When the utility model is used, the closing door 6 is closed and the motor 7 is started, wastewater is introduced into the water inlet 3, the wastewater enters the inner side of the filter screen 2 and flows to the outer side to complete filtration, the filtered impurities are accumulated on the inner side of the filter screen 2, and the filtered purified water is discharged through the water outlet 4; meanwhile, the motor 7 drives the scraper 8 to rotate through the gear speed reducing mechanism, and the scraper 8 drives the filter screen 2 to rotate through the overrunning bearing 9, so that the wastewater in the filter screen 2 is stirred to generate vortex flow, the centrifugal force generated by the flow can accelerate the filtering speed of the purified water towards the outer side of the filter screen 2, and impurities are tightly attached to the inner surface of the filter screen 2 under the action of the centrifugal force.
After the operation is carried out for a period of time, impurities on the inner surface of the filter screen 2 are gradually increased to influence the filtering effect, at the moment, the introduction of wastewater is stopped, the motor 7 is stopped, the closed door 6 is opened, the scraper 8 is stopped after the motor 7 is stopped, but the overrunning bearing 9 is in a power off state at the moment, so that the filter screen 2 continues to rotate under the action of inertia, the scraper 8 and the filter screen 2 generate relative rotation, and sliding friction is generated between the scraper 8 and the inner edge surface of the filter screen 2 to scrape off the impurities accumulated on the filter screen 2; impurity is scraped the back and is dropped and discharge drain 5 downwards under the action of gravity, accomplishes the clearance of filter screen and the discharge of impurity.
The utility model utilizes the rotating filter screen and the scraper to stir water flow to generate centrifugal force so as to accelerate the filtering speed of waste water, and utilizes the inertial motion to generate relative rotation between the scraper and the filter screen after the motor stops rotating so as to realize the timely cleaning of the filter screen, the filter screen is not easy to be damaged, the cleaned impurities are directly discharged from the sewage outlet, and the waste water filtering operation can be carried out by closing the closed door again; the full-automatic filtering, net cleaning and sewage discharging of the wastewater can be realized by utilizing the electromagnetic valve, the electronic lock and the simple chip control, the filtering efficiency is high, the effect is good, the structure is simple and compact, the operation and the maintenance are simple, and the device is suitable for most wastewater treatment occasions.
