Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to a supermagnetic separator based on magnetic seed recovery. Background Art

[0002] The magnetic coagulation system process is a water treatment technology developed by combining magnetic coagulation sedimentation process, magnetic separation process, intelligent dosing and intelligent control technology. It is mainly used in the fields of municipal sewage deep treatment, upgrading and transformation, industrial sewage deep treatment and zero discharge of sewage and wastewater.

[0003] Magnetic coagulation and sedimentation technology (also known as magnetic loading-coagulation technology) is a new water treatment technology that adds magnetic loading materials (Magnetite Ballast) to increase the density of flocs formed by coagulation or flocculation of suspended bodies in the traditional coagulation and sedimentation water treatment process, and combines magnetic separation to recycle the magnetic loading materials. Magnetic loading agents (also generally called magnetic seeds) are added simultaneously in the ordinary coagulation and sedimentation process. They are called the core of the alum flocs in the flocculation process and play a heterogeneous nucleation role, so that they are connected with the pollutant flocculation to improve the density of the coagulation flocs, make the generated flocs denser and stronger, and shorten the formation, aggregation and sedimentation time of the alum flocs, so as to achieve the purpose of high-speed sedimentation. The magnetic seeds can be recovered for recycling through magnetic separation drums or similar magnetic recovery devices.

[0017] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0018] The following is a detailed description of the implementation method of the present invention in conjunction with the accompanying drawings. Only some embodiments are described, not all embodiments. For the purpose of clarity, representations and descriptions that are not related to the present invention are omitted in the drawings and descriptions.

[0019] In order to have a clearer understanding of the technical features, purposes and beneficial effects of the utility model, the technical solution of the utility model is now described in detail below. Obviously, the implementation cases described are part of the embodiments of the utility model, not all of the embodiments, and cannot be understood as limiting the scope of implementation of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0020] like Figure 1 As shown, the utility model provides a super magnetic separator based on magnetic seed recovery, including a feed pipe 1, a floc dispersion box 2, a magnetic separation drum 3, a magnetic seed stirring box 5, a magnetic seed agitator 4, and a magnetic seed output pipe 6; the magnetic seed stirring box 5 is a rectangular parallelepiped as a whole, with a square opening on the upper left side, which is connected to the floc dispersion box 2; the feed pipe 1 is arranged on the front side of the floc dispersion box 2 near the upper left side, and the magnetic separation drum 3 is arranged in the center of the front side; the magnetic seed agitator 4 is arranged above the magnetic seed stirring box 5; the magnetic seed output pipe 6 is arranged on the right side of the magnetic seed stirring box 4.

[0021] It also includes an emptying pipe 7 and a mud discharge pipe 8; both of the emptying pipe 7 and the mud discharge pipe 8 are arranged on the floc dispersion box 2; the emptying pipe 7 is located directly below the magnetic separation drum 3, and the mud discharge pipe 8 is arranged parallel to the right side of the emptying pipe 7.

[0022] A high-speed shearing machine 9 is arranged above the floc dispersion box 2, and the high-speed shearing machine 9 is used to separate the magnetic seed from the flocculent. The magnetic seed and the flocculent combine to form flocs. When recycling, the high-speed rotary shearing action of the high-speed shearing machine 9 is required to separate the magnetic seed and the flocculent. The magnetic seed is recycled by the magnetic drum and reused, and the flocculent enters the sludge tank for further treatment.

[0023] It also includes a magnetic seed water supply pipe, which is arranged on the magnetic seed stirring box 5 and is located on the right side of the magnetic seed stirrer 4. When stirring the magnetic seed, the magnetic seed and water need to be stirred to form a mixed liquid, and the concentration of the magnetic seed in the mixed liquid needs to be adjusted according to the process conditions. Therefore, when the concentration of the magnetic seed is high or the amount of water is insufficient, water needs to be supplied to the stirring box through the water supply pipe.

[0024] The magnetic seed output pipe 4 consists of an output pipe and an output nozzle; the output nozzle is a rectangular parallelepiped with a square raised opening on the right side; the output pipe is connected to the lower right side of the magnetic seed mixing box 5. A regulating valve is provided on the output pipe, and the regulating valve is used to adjust the rate of magnetic seed output. A placing clamp is provided on the right side of the magnetic seed mixing box 5, and the placing clamp is used to place the magnetic seed output pipe 6 in an idle state.

[0025] The working principle of the super magnetic separator described in the utility model is as follows: the slag separated by the super magnetic separator is a magnetic floc formed by the magnetic seed and the suspended matter under the action of the coagulant. After being transported out of the equipment by the spiral conveying device of the super magnetic separator, it flows by gravity into the high-speed stirring unit of the magnetic seed recovery system through the pipeline, and the cutting blades are dispersed under the floc disperser. After the magnetic seed and the suspended matter are broken up and separated, they are mixed in the water and overflow into the magnetic separation drum, and the magnetic seed is adsorbed on the drum designed with a special magnetic circuit. The magnetic drum rotates continuously, and the magnetic seed separated from the mixed liquid is recovered into the magnetic seed mixing box. The non-magnetic suspended matter is discharged from the mud discharge pipe with the water flow, and the cleaned magnetic drum enters the next cycle. This process completes the recovery of the magnetic seed. The magnetic seed is diluted into a solution of a certain concentration by adding water in the magnetic seed mixing box, and is continuously mixed and evenly mixed under the action of the magnetic seed stirring.

[0026] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
