As an embodiment of the present invention, the insertion block 54 and the ring plate 632 are made of magnetic materials, and the insertion block 54 and the ring plate 632 repel each other;
when the floating type waste water treatment device works, the inserting block 54 and the ring plate 632 are made of magnetic materials, the inserting block 54 and the ring plate 632 are mutually repelled, so that after the floating plate 52 is attracted by the electromagnet at the extending end of the electric push rod 55, waste water in the cavity 61 in the floating plate 52 still remains in the cavity 61, and the waste water cannot completely flow out along the through hole 523, so that the ring plate 632 with certain buoyancy still floats on the surface of the waste water in the cavity 61, and moves towards the top wall of the shell 1 along with the floating plate 52, the ring plate 632 approaches to the lower end of the inserting block 54, and the ring plate 632 and the lower end of the inserting block 54 are mutually repelled, so that under the action of the inserting block 54, the ring plate 632 moves downwards in the cavity 61 of the floating plate 52, the floating plate 52 drives the sliding block 63 to move downwards on the connecting column 62 through the connecting rod 631, so that after the inserting block 54 is inserted into the ring groove 522, the cavity 61 is deep enough in the height direction of the shell 1, thereby effectively avoiding the inserting block 54 from being inserted into the ring groove 522, insert 54 lower extreme extrusion heater strip 633 problem, improve this device's life, improve the result of use of this application.
As an embodiment of the present invention, a connecting block 7 is arranged inside each through hole 523, a drainage needle 8 is arranged below the connecting block 7, and the lower end of the drainage needle 8 extends out of the through hole 523;
when the device works, after the floating plate 52 is sucked up by the electromagnet at the extending end of the electric push rod 55, the waste water in the cavity 61 inside the floating plate 52 drops onto the upper surface of the waste water below the floating plate 52 through the through hole 523, waves are easily generated on the upper surface of the waste water, so that more oil bubbles are generated on the surface of the waste water, after the floating plate 52 is placed on the waste water again, the oil bubbles are upwards surged and placed on the surface of the waste water again, at the moment, the more oil bubbles block the sponge 53 from absorbing the oil on the surface of the waste water, and the efficiency of removing the oil on the surface of the waste water is reduced; at this moment, through having set firmly connecting block 7 in through-hole 523 inside, connecting block 7 lower extreme is to the slope of through-hole 523 bottom (as shown in figure 4), connecting block 7 below sets firmly drainage needle 8, drainage needle 8 is olive form, its upper and lower tip is most advanced form, the diameter that is close to the upper end is greater than the through-hole 523 diameter, make the waste water that through-hole 523 flows can flow through drainage needle 8 surfaces, finally in the waste water of casing 1 inside is remitted to 8 lower extremes of drainage needle, with this fluid bubble that produces on reducing the waste water below floating plate 52, improve the result of use of this application.
As an embodiment of the present invention, the floating plate 52 and the inner wall of the casing 1 are both coated with PTFE coatings;
during operation, through spraying the PTFE coating on kickboard 52 and the casing 1 inner wall, the PTFE coating possesses certain self-lubricating effect to this makes sponge 53 after the extrusion that receives kickboard 52 and casing 1 roof, the fluid that sponge 53 appeared can be quick remove on kickboard 52 surface, flows out through play oil pipe 4 at last, improves fluid at the removal rate on kickboard 52 surface, improves the deoiling efficiency of this application.
The specific implementation flow is as follows:
wastewater enters the shell 1 through the water inlet pipe 2 arranged on the side wall below the shell 1, oil floats on the surface of the wastewater, the floating plate 52 floats on the surface of the wastewater in the shell 1, and along with the rise of the water level in the shell 1, the convex blocks 521 arranged on the surface of the periphery of the floating plate 52 slide in the sliding grooves 51 vertically arranged on the inner wall of the shell 1, so that the floating plate 52 is limited, the floating plate 52 is prevented from shaking along with the waves generated on the surface of the wastewater and impacting the inner surface of the shell 1, thereby prolonging the service life of the floating plate 52, after the water inflow and the water outflow in the shell 1 tend to be stable, the floating plate 52 is located at the upper part of the inner part of the shell 1, at this time, the water in the inner part of the shell 1 enters the annular groove 522 arranged on the upper surface of the floating plate 52 through the through hole 523 arranged on the lower surface of the floating plate 52, the sponge 53 is arranged on the upper surface of the floating plate 52, so that the oil liquid exposed from the waste water through the surface of the ring groove 522 can be sucked;
when the sponge 53 absorbs oil to a certain degree, the controller controls the external water inlet device to stop feeding water into the shell 1 through the water inlet pipe 2, meanwhile, the controller arranged on the shell 1 controls the electric push rod 55 to work, the extending end of the electric push rod 55 moves towards the lower part of the inside of the shell 1, because the central axis of the extending end of the electric push rod 55 is coincident with the central axis of the floating plate 52, the middle part of the floating plate 52 is made of magnetic material, so that after the extending end of the electric push rod 55 is close to the middle part of the upper surface of the floating plate 52, the controller controls the electromagnet to work, the electromagnet is attached to the floating plate 52, then the controller controls the electric push rod 55 to work, the extending end of the electric push rod 55 moves towards the top wall of the shell 1, the insertion block 54 arranged on the top wall of the shell 1 is inserted into the annular groove 522 to block the annular groove, then under the action of the electric push rod 55, the sponge 522 arranged on the floating plate 52 is contacted and extruded with the top wall of the shell 1, the oil adsorbed in the sponge 53 flows out, a plurality of holes formed in the upper part of the inserting block 54 are used for allowing the oil separated out from the sponge 53 in the inner ring part of the inserting block 54 to pass through, the oil on the upper surface of the floating plate 52 is finally conveyed to the outside through the oil outlet pipe 4, after the sponge 53 is extruded, the controller controls the electric push rod 55 to work, the extending end of the electric push rod 55 moves towards the lower part of the inner part of the shell 1, when the floating plate 52 contacts the upper surface of the waste water, the controller controls the electromagnet to stop working, the floating plate 52 floats on the surface of the waste water again, and the sponge 53 arranged on the upper surface of the floating plate absorbs the oil on the surface of the waste water again;
the problem that oil liquid cannot float on the surface of the floating plate 52 due to different densities of waste water in the shell 1 can be solved by controlling the electromagnet arranged at the lower end of the electric push rod 55, namely when the oil liquid does not float on the surface of the floating plate 52, the extending end of the electric push rod 55 is controlled to move downwards at the moment, the electromagnet arranged on the electric push rod 55 works, so that the floating plate 52 is pressed downwards under the action of the electromagnet and the electric push rod 55, and the oil liquid floats on the surface of the floating plate 52 and is absorbed by the sponge 53; when fluid floated out the kickboard 52 surface, the electro-magnet work that sets up on the electric putter 55, and electric putter 55 stretches out the end upward movement, upwards attracts kickboard 52 under the effect of electro-magnet to this makes fluid can accurately float in kickboard 52 surface position, improves the separation accuracy of fluid and waste water.
