Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a magnetic separation device based on wastewater carbon source concentration treatment. Background Art

[0002] Wastewater treatment is particularly important for ecological health. Magnetic separation technology is an efficient solid-liquid separation technology that plays an important role in the carbon source concentration treatment of wastewater. Its basic principle is to use the force characteristics of magnetic particles in the magnetic field to separate the magnetic substances in the wastewater or the pollutants adsorbed by the magnetic substances from the water phase. The working process is as follows: First, magnetic seeds are added to the wastewater. These magnetic seeds are fully mixed with the carbon source in the wastewater under the action of the stirring device. The magnetic seeds will adsorb the organic carbon source particles in the wastewater to form a magnetic complex with a carbon source. Then, the wastewater enters the magnetic separation tank. Under the action of the magnetic field, the magnetic complex is captured by the magnetic field and moves toward the magnet, and finally gathers on the inner wall or bottom of the separation tank. The clean water after magnetic separation flows out through the outlet, achieving the effect of separating the carbon source from the water phase. Finally, the magnetic agglomerates containing the carbon source are regularly discharged through the slag discharge port for subsequent carbon source recovery or further treatment.

[0003] In the prior art, a water baffle is usually installed in the magnetic separation tank to slow down the flow rate of wastewater. However, since the water baffle is usually fixedly installed, the effect of slowing down the flow rate of wastewater is poor and the residence time of wastewater in the magnetic separation tank cannot be fully extended. Therefore, it is necessary to provide a new water baffle installation structure for the magnetic separation tank to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a magnetic separation device based on wastewater carbon source concentration treatment to solve the problem raised in the above background technology that in the prior art, a water baffle is usually installed in the magnetic separation tank to slow down the flow rate of the wastewater, but because the water baffle is usually fixedly installed, the effect of slowing down the flow rate of the wastewater is not good and the residence time of the wastewater in the magnetic separation tank cannot be fully extended.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model is a magnetic separation device based on wastewater carbon source concentration treatment, comprising:

[0007] A magnetic separation tank body;

[0008] An extended wastewater retention component includes a water baffle, a receiving plate, an L-shaped plate, a circular ring, a circular groove and a shaft rod. The top of the magnetic separation tank body is movably connected to the receiving plate, and the water baffle is movably connected in the magnetic separation tank body. Both sides of the top of the receiving plate are fixedly connected to one end of the L-shaped plate, and the other end of the L-shaped plate is fixedly connected to the circular ring. A circular groove is provided through the middle of the circular ring, the bottom of the water baffle is fixedly connected to the shaft rod, and the circular groove is movably connected to the shaft rod.

[0009] Furthermore, the wastewater retention extension component also includes a limiting ring, and the bottom of the shaft is fixedly connected to the limiting ring.

[0010] Furthermore, the wastewater retention extension component also includes a through hole, a threaded groove and a butterfly screw. Through holes are formed at both ends of the receiving plate, a threaded groove is formed on the main body of the magnetic separation tank, and a butterfly screw is movably inserted between the through hole and the threaded groove.

[0011] Furthermore, it also includes a high-efficiency separation component, which includes a triangular prism, and the triangular prism is fixedly connected to the main body of the magnetic separation tank.

[0012] Furthermore, the high-efficiency separation component also includes a first magnetic attraction plate and a second magnetic attraction plate, and the first magnetic attraction plate and the second magnetic attraction plate are fixedly installed on the inner walls on both sides of the magnetic separation tank body at an angle.

[0013] Furthermore, the high-efficiency separation component also includes a magnetic mesh plate, and the outlet end of the magnetic separation tank body is fixedly connected to the magnetic mesh plate.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] In the utility model, with the cooperation of the shaft and the circular ring, when the water baffle is impacted by wastewater, the force generated at this time will drive the water baffle to rotate in the main body of the magnetic separation tank, thereby dynamically changing the direction of the wastewater flow, so that the wastewater flow forms a more complex path in the main body of the magnetic separation tank, thereby effectively extending the residence time of the wastewater, and further allowing the magnetic particles to have more opportunities to interact with the magnetic field, thereby improving the separation effect.

[0016] Based on the above beneficial effects, the tip of the front end of the triangular prism can divert the wastewater flow into two streams, so that the wastewater flow rate at the adsorption part is reduced accordingly, thereby improving the adsorption effect of the magnetic separation tank body on the magnetic particles. At the same time, the installed magnetic suction mesh plate can fully contact and adsorb the magnetic particles distributed in the wastewater. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Magnetic separation tank body 101;

The top of the magnetic separation tank body 101 is movably connected to the receiving plate 202, and the water baffle 201 is movably connected in the magnetic separation tank body 101. The two sides of the top of the receiving plate 202 are fixedly connected to one end of the L-shaped plate 203, and the other end of the L-shaped plate 203 is fixedly connected to the ring 204. The middle of the ring 204 is penetrated by a circular groove 205. The bottom of the water baffle 201 is fixedly connected to the shaft 206, and the shaft 206 is movably connected in the circular groove 205;

[0033] The receiving plate 202 provides a carrier for the connection of components, the L-shaped plate 203 is used to receive the connection between components, the circular groove 205 on the ring 204 provides a guarantee for the movable connection of the shaft 206, and the water baffle 201 rotates to change the wastewater path.

[0034] The wastewater retention extension assembly further includes a limit ring 207, and the bottom of the shaft 206 is fixedly connected to the limit ring 207;

[0035] The setting of the limiting ring 207 can prevent the shaft 206 from being separated from the ring 204 .

[0036] The wastewater retention extension component further includes a through hole 208, a threaded groove 209 and a butterfly screw 2010. Through holes 208 are formed at both ends of the receiving plate 202, and a threaded groove 209 is formed on the magnetic separation tank body 101. The butterfly screw 2010 is movably inserted between the through hole 208 and the threaded groove 209.

[0037] The through hole 208 , the threaded groove 209 and the butterfly screw 2010 are used in conjunction with each other to provide a guarantee for the installation and removal of the receiving plate 202 on the magnetic separation tank body 101 .

[0038] It also includes a high-efficiency separation component, which includes a triangular prism 301, and the triangular prism 301 is fixedly connected to the magnetic separation tank body 101;

[0039] The triangular prism 301 can realize wastewater diversion.

[0040] The high-efficiency separation component also includes a first magnetic attraction plate 302 and a second magnetic attraction plate 303. The first magnetic attraction plate 302 and the second magnetic attraction plate 303 are fixedly installed on the inner walls of both sides of the magnetic separation tank body 101.

At this time, the water baffle 201 is impacted by the wastewater. Since the shaft 206 is movably connected in the circular groove 205, the force generated by the wastewater will drive the water baffle 201 to rotate. When the water baffle 201 rotates, the flow path of the wastewater is changed. Then the wastewater is divided into two streams at the triangular prism 301, and then flows through the first magnetic attraction plate 302 and the second magnetic attraction plate 303, and then flows out through the magnetic attraction mesh plate 304. In this process, the magnetic force generated by the magnetic separation tank body 101, the first magnetic attraction plate 302, the second magnetic attraction plate 303 and the magnetic attraction mesh plate 304 adsorbs the magnetic particles composed of the magnetic seeds and the carbon source. This step fully improves the separation effect of the carbon source in the wastewater.
