Example 6:

referring to fig. 9, 10 and 11, in this embodiment, a flow guide mechanism is further provided between the two support baffles 10, and one end of the flow guide mechanism is connected to the water inlet 11, and the flow guide mechanism can guide the water flow entering between the two support baffles 10 to the magnetic disk 23.

In one specific implementation scenario, the water flow from the diversion mechanism is diverted onto the magnetic disc 23 in a jetting manner, so as to improve the adsorption efficiency of the magnetic stripe 22. The injection may be achieved by arranging a booster mechanism at the water inlet 11 to increase the degree of injection of the water stream.

The flow guide mechanism specifically comprises a flow guide part 41 communicated with the water inlet 11 and a flow guide part 42 communicated with the flow guide part 41, wherein the flow guide part 41 is basically covered in the middle of the plate surface of the magnetic disk 23, and meanwhile, the projection length of the flow guide part 42 on the magnetic disk 23 is more than or equal to one half of the length of the magnetic disk and less than or equal to three quarters of the length of the magnetic disk 23. The number of the air guide mechanisms may be the same as the number of the disks 23, or the number of the air guide portions 42 may be the same as the number of the disks 23, for example, in the structure shown in fig. 10, the number of the disks 23 is three, and the number of the air guide mechanisms and the air guide portions 42 is three.

The flow guide mechanism is internally provided with a stirring assembly 43, and the stirring assembly 43 is in transmission connection with the transmission shaft 32 through a gear set 50. When the transmission shaft 32 rotates, the gear set 50 is driven to rotate, so that the stirring assembly 43 can be driven to work. It should be understood that in fig. 9, for better illustration of the stirring assembly 43, one wall of the flow guide portion 42 is purposely omitted, and the flow guide portion 42 has uniformly distributed injection holes (not shown) in the direction toward the magnetic disk 23.

In this embodiment, the water flow can be guided to the adsorption area of the magnetic disc 23 better by adding the flow guiding mechanism, and turbulence of the water flow in the area where the magnetic disc 23 is disposed is disturbed, so that the adsorption mechanism 20 (composed of the magnetic disc 23 and the magnetic strip 22) can adsorb the magnetic floccules better.

In an implementation scenario, referring to fig. 5, the middle portion of the magnetic disc 23 has a plurality of guiding grooves 232 penetrating through two side surfaces of the magnetic disc 23, a guiding groove 232 is disposed between two adjacent magnetic strips 22, and the length of the guiding groove 232 is greater than or equal to the length of the projection of the guiding portion 42 on the magnetic disc 23. The water flow enters the diversion trench 232, and because the two sides of the diversion trench 232 are both provided with the magnetic strips 22, the magnetic floccules in the water flow are more easily captured by the magnetic strips 22. The magnetic flocks are pushed to the end of the magnetic disk 23 by the blade 21 reciprocating on the magnetic disk 23. Thereby separating the magnetic flocks in the water stream.

Example 7:

referring to fig. 8, 10, 11, 12 and 13, the water purifying apparatus further comprises a collecting mechanism 60 disposed between the two support baffles 10, wherein the collecting mechanism 60 comprises a driving member, an endless chain 61 and a sweeping member.

Specifically, the collecting mechanism 60 includes two magnetic endless chains 61, the endless chains 61 may be a link plate type chain, and the two endless chains 61 are correspondingly disposed at the end portions of the magnetic disks 23, respectively bypass the release area 231 at the end portion of each magnetic disk 23, and extend to the water surface. Used for adsorbing and lifting the magnetic floccules scraped to the end part of the magnetic disc 23 out of the water surface to realize the collection of the magnetic floccules. In a specific implementation scenario, in order to better lift the magnetic flocks in the disengagement area 231 to the upper side by the endless chain 61, a plurality of magnetic plates can be hung on the endless chain 61 at equal intervals, and the contact area with the disengagement area 231 is increased by the plates, so that the magnetic flocks can be more efficiently taken away from the water surface to be collected.

The driving member is a motor, and the output end of the driving member is connected to the upper part of the endless chain 61 through a gear to drive the endless chain 61 to rotate circularly around the end of the magnetic disk 23. The end part of the magnetic disc 23 is provided with a guide wheel 63 which is matched with the annular chain 61, the guide wheel 63 is rotatably arranged on the rotating shaft 62 and plays a role in limiting and guiding the annular chain 61, so that the annular chain 61 passes through a separation area 231 at the end part of the magnetic disc 23, and separated magnetic floccule is adsorbed and carried away from a water body.

The cleaning member is in contact with the upper part of the endless chain 61 and is used for sweeping down the magnetic floccules on the endless chain 61 for recovery. Specifically, the cleaning element may include an annular brush body disposed at the front end of the driving element, and the annular chain 61 is disposed in the annular brush body, so that the annular chain 61 can clean the substances adsorbed on the surface through the annular brush body during operation.

After the magnetic floccules on the magnetic disk 23 are scraped by the scraper 22, the magnetic floccules are adsorbed by the annular chain 61, meanwhile, the driving element drives the annular chain 61 to move the magnetic floccules out of the water body, and the magnetic floccules on the annular chain 61 are swept down and recovered by a sweeping element outside the water surface, so that the separation of water flow and the magnetic floccules is realized.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
