Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.
Referring to fig. 1 to 3, an embodiment of the present invention discloses a magnetic separation backflow device, which includes a water tank 100 and a magnetic separation mechanism disposed in the water tank 100; a lifting conveyor 300 is also disposed in the tank 100, the feeding end of the lifting conveyor 300 is located at the bottom of the tank 100, and the discharging end of the lifting conveyor 300 extends out of the tank 100 in an oblique upward direction.
The lifting type conveying mechanism 300 arranged in the water tank 100 can lift the magnetic flocs precipitated in the water tank 100 out of the water surface, so that the water lifted together with the magnetic flocs is drained off, and the magnetic flocs are returned and put into a coagulation reaction system, so that the unreacted coagulation medicament in the magnetic flocs can be reused for coagulation reaction; therefore, the flocculation effect is improved by facilitating the full reaction of the coagulation medicament, the formed floc is more compact, the waste of the coagulation medicament can be avoided, the dosage of the coagulation reaction is reduced, and the cost of sewage treatment is reduced; the non-precipitated magnetic flocs flow to the magnetic separation mechanism and are subjected to magnetic adsorption separation through the magnetic separation mechanism.
Specifically, the water tank 100 is provided with a water inlet 101 and a water outlet 102, and the water inlet 101 and the water outlet 102 are respectively located at two sides of the magnetic separation mechanism, so that the sewage coming out from the coagulation reaction system enters the water tank 100 through the water inlet 101, part of the magnetic flocs precipitate and are returned to the coagulation reaction system for recycling through the lifting type conveying mechanism 300 in the process that the sewage entering the water tank 100 flows from the water inlet 101 to the magnetic separation mechanism, the magnetic flocs which do not sink at the bottom flow to the magnetic separation mechanism and are magnetically adsorbed and separated by the magnetic separation mechanism, and further the purified water passing through the magnetic separation mechanism is discharged out of the water tank 100 from the water outlet 102.
Because the precipitation of magnetic flocs mainly takes place in the process that sewage flows to the magnetic separation mechanism from the water inlet 101, in order to better ensure that the lifting type conveying mechanism 300 carries out the backflow reutilization on the magnetic flocs precipitated in the water tank 100, the lifting type conveying mechanism 300 can be arranged on one side of the water inlet 101 of the magnetic separation mechanism, so that the lifting type conveying mechanism 300 is positioned in the precipitation area of the magnetic flocs, and the backflow conveying effect of the lifting type conveying mechanism 300 on the precipitated magnetic flocs is ensured.
Meanwhile, the water inlet 101 may be disposed on the top wall of the water tank 100 and located above the lifting type conveying mechanism 300, so that the magnetic flocs entering the water tank 100 through the water inlet 101 have a larger settling height, and are more easily precipitated at the lifting type conveying mechanism 300 at the bottom of the water tank 100 under the action of gravity of the magnetic flocs and the driving of water flow, thereby ensuring the backflow lifting conveying effect of the lifting type conveying mechanism 300 on the precipitated magnetic flocs; the water outlet 102 is disposed on a side wall of the water tank 100, such that the position of the water outlet 102 is lower than the position of the water inlet 101, which is more beneficial for the purified water to exit the water tank 100 from the water outlet 102.
In order to adjust and control the liquid level in the water tank 100, as shown in fig. 1, a hole plate for controlling the water level may be disposed in the water tank 100, and the hole plate is located between the magnetic separation mechanism and the water outlet 102, and separates the water tank 100 into a water inlet area and a water outlet area; the magnetic separation mechanism is located in the water inlet zone and the water outlet 102 is located in the water outlet zone.
The water inlet area is provided with a plurality of rows of through holes, and the water in the water inlet area flows into the water outlet area through the through holes of the pore plate; when the liquid level of the water inlet area is low, only the through holes in the bottom row of the pore plate can be used for passing water, so that the water passing amount of the through holes of the pore plate is smaller than the water inlet amount of the water inlet 101, and the water level in the water inlet area rises; the quantity of the through holes through which the pore plate can pass water is increased along with the rising of the water level, so that the water passing quantity of the pore plate is gradually increased, and when the water inlet quantity of the water inlet 101 and the water passing quantity of the pore plate reach dynamic balance, the liquid level is kept unchanged; therefore, the purpose of controlling the water level of the water inlet area can be achieved through the pore plate, and the magnetic separation mechanism is partially positioned below the liquid level and partially positioned above the liquid level so as to adsorb and separate the magnetic flocs in the water inlet area.
It is easy to understand that, in order to gather the magnetic flocs deposited at the bottom of the water tank 100, as shown in fig. 2, the bottom of the water tank 100 may be provided with a material collecting surface 103, and the material collecting surface 103 forms a horn-shaped structure with a large top and a small bottom at the bottom of the water tank 100, so that the magnetic flocs deposited at the bottom of the water tank 100 can slide along the material collecting surface 103 and be gathered together, thereby being more beneficial to the backflow lifting conveying of the lifting type conveying mechanism 300 on the deposited magnetic flocs; the material collecting surface 103 can be an inclined surface or an arc curved surface.
In the magnetic separation reflux device disclosed in the embodiment of the present invention, as a specific structure of the lifting type conveying mechanism 300, it may be a screw conveyor; generally, a screw conveyor comprises a housing, a screw shaft and a driving motor, wherein the screw shaft is arranged in the housing and can be in transmission connection with an external driving motor; the shell provides a bearing foundation for the installation of the spiral shaft, and the driving power supply provides power for the rotation of the spiral shaft, so that the lifting and conveying of materials are realized through the rotation of the spiral shaft.
Meanwhile, a feed port is formed in the feed end of the spiral conveyor and is positioned on the top side of the spiral conveyor, so that the precipitated magnetic flocs can enter the shell more easily through the feed port on the top side and can be lifted and conveyed under the rotation of the spiral shaft; the discharge end of the screw conveyor is provided with a discharge port 310, and the discharge port 310 is positioned at the bottom side of the screw conveyor, so that the magnetic flocs lifted to the top end along the screw conveyor can automatically flow into the coagulation reaction system through the discharge port 310, the returned magnetic flocs can automatically fall into the coagulation reaction device, the unreacted coagulation agent contained in the magnetic flocs can participate in the reaction again, and the conveying resistance and the energy consumption of the screw conveyor can be reduced.
Preferably, the feed inlet is located directly below the magnetic separation mechanism; in the process that the magnetic flocs flow from the water inlet 101 to the magnetic separation mechanism, the part of the magnetic flocs which is not precipitated flows to the magnetic separation mechanism under the action of water flow and is adsorbed and separated, and the part of the magnetic flocs which is precipitated is mainly precipitated below the magnetic separation mechanism under the action of water flow, so that the precipitated magnetic flocs can better enter the spiral conveyor to be lifted and conveyed by arranging the feed inlet in the area right below the magnetic separation mechanism.
