It should be noted that the dirt collecting member 23 is installed in the annular cavity of the inner wall of the filtering pipe 21, so that the flow speed of water is not affected, and impurities are collected towards the circumferential direction of the water filtering net 19 under the action of centrifugal force and then collected by the dirt collecting member 23, so that the water filtering net 19 is kept in an unobstructed state. The dirt collecting part 23 is a fiber bundle filter material, and the fiber bundle filter material can utilize a large amount of biological clusters attached to the surface of the fiber bundle filter material and oxygenate, so that tiny suspended matters which are not easy to precipitate and remove are intercepted and organic matters are degraded, and the purpose of purification is achieved.
As shown in fig. 1 to fig. 8, an embodiment of the present invention further provides a filtering method of an air source heat pump unit, where the filtering assembly of the air source heat pump unit includes the following steps:
when the air source heat pump unit normally works, the double-shaft motor 8 rotates positively, the double-shaft motor 8 drives the fan blades 12 and the power wheel 11 to rotate positively, so that air enters the air inlet channel 1, and the driven wheel 10 keeps a static state at the moment.
When the air filter mechanism is automatically cleaned, the double-shaft motor 8 reverses, the double-shaft motor 8 drives the fan blade 12 and the power wheel 11 reverse rotation, make inlet air channel 1 exhaust, power wheel 11 drives under the effect of ratchet external tooth 14 and pawl 15 and rotates from driving wheel 10, drive shaft 6 through reduction gear 9 from driving wheel 10 and rotate, drive shaft 6 makes driving lever 20 rotate, constantly hit when driving lever 20 rotates and beat group post 41, make dust filter screen 4 rock under the effect of go-between 13, dust filter screen 4 makes the dust on it drop when rocking, the dust blows to the outside of filter 3 under the effect of exhaust wind, debris on the filter 3 blows off under the effect of exhaust wind.
The during operation of the water inlet filtering mechanism, the water inlet pipeline 2 continuously feeds water, the water flows in a rotating mode under the action of the spiral channel 74 in the spiral piece 7, when the water passes through the water filter screen 19, the water filter screen 19 filters impurities, the impurities are gathered in the circumferential direction of the water filter screen 19 under the action of centrifugal force, and part of the impurities drop under the action of gravity.
It should be noted that, in the invention, the motor driving the fan blades 12 to rotate is used for driving the shift lever 20 to rotate at the same time, so that the dust filter screen 4 shakes, and further, the motor for shaking the dust filter screen 4 is not required to be arranged, so that the structure of the mechanism is simplified, and meanwhile, when the mechanism cleans dust, the wind direction is changed, so that the dust can be blown out of the mechanism, therefore, the dust removal effect is good, and the efficiency is high. The invention utilizes the characteristic of water flow to lead the impurities to be gathered towards the circumferential direction of the water filter screen 19 under the action of centrifugal force, thereby realizing the purpose of removing the impurities.
In this embodiment, it is apparent to those skilled in the art that the present invention is not limited to the details of the above-described exemplary embodiments, and can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
