DETAILED DESCRIPTION

[0022] The technical solutions of the utility model will be described clearly and completely in combination with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] As shown in the accompanying drawings Fig. 1 to the accompanying drawings Fig. 2 It is shown that a recycling device for magnetic materials comprises a device main body 1, a first chamber 2 arranged in the device main body 1, and an electromagnet 3 and a stirring device 4 arranged in the first chamber 2, wherein the electromagnet 3 is fixedly arranged on the inner wall surface of the first chamber 2, and the stirring device 4 is arranged at the inner center of the first chamber 2. In use, waste liquid containing magnetic materials can be introduced into the first chamber 2, and then the waste liquid is mixed and stirred by the stirring device 4. In the stirring process, the magnetic materials in the waste liquid are adsorbed by the electromagnet 3, so that the separation of the magnetic materials can be realized.

[0024] The stirring device 4 mainly comprises a motor, a rotating shaft and a plurality of groups of stirring paddles. The motor is arranged below the first chamber 2, the rotating shaft is rotatably arranged at the inner center of the first chamber 2, and the lower end of the rotating shaft is connected to the transmission shaft of the motor. The stirring paddles are arranged on the outer wall of the upper end of the rotating shaft. This design allows the rotating shaft to rotate in the first chamber 2 driven by the motor, and the waste liquid in the first chamber 2 can be mixed and stirred by the stirring paddles during rotation. The centrifugal force generated during stirring can make the waste liquid fully contact with the electromagnet 3, so that the magnetic materials in the waste liquid can be uniformly adsorbed.

[0025] Further, at least two water inlet pipes 5 are arranged between the upper surface of the device main body 1 and the inner wall surface of the first chamber 2. In use, the waste liquid containing magnetic materials outside can be introduced into the first chamber 2 through the water inlet pipes 5 for treatment.

[0026] Further, the first chamber 2 has a cylindrical structure, and the electromagnet 3 is fixedly arranged along the circumferential direction on the inner wall surface of the first chamber 2. This design allows the electromagnet 3 to form a ring structure, so that the waste liquid can uniformly contact with the electromagnet 3 when it is mixed and stirred in the first chamber 2.

[0027] Based on the above embodiment, a drain pipe 6 is fixedly arranged at the lower end of the first chamber 2 in the horizontal direction, a first electromagnetic valve 9 is arranged at the right side of the drain pipe 6, then a first branch pipe 7 is arranged in communication between the drain pipe 6 and the inner wall bottom end of the first chamber 2, and a second electromagnetic valve 10 is further arranged at the first branch pipe 7. In this way, in use, two groups of electromagnetic valves can be opened, and the separated waste liquid can enter the drain pipe 6 through the first branch pipe 7 for discharge.

[0028] Meanwhile, a second chamber 12, a magnetic material recovery chamber 13 and a sampling temporary storage chamber 14 are respectively formed in the equipment body 1 below the drain pipe 6, the second chamber 12 is also provided with a corresponding stirring device 4, and the second chamber 12, the magnetic material recovery chamber 13 and the sampling temporary storage chamber 14 are all arranged in communication with the drain pipe 6 through a second branch pipe 8, and a corresponding second electromagnetic valve 10 is arranged on each second branch pipe 8. This design enables the magnetic material in the first chamber 2 to enter the second chamber 12, the magnetic material recovery chamber 13 and the sampling temporary storage chamber 14 through the drain pipe 6 and the second branch pipe 8 for processing. For example, when recovering the magnetic material, the electromagnet 3 can be disconnected first, then clean water is poured into the first chamber 2 to mix with the magnetic material, and after mixing, the mixture enters the drain pipe 6 through the first branch pipe 7, and then the clean water containing the magnetic material or the waste liquid containing the magnetic material can enter the second chamber 12, the magnetic material recovery chamber 13 or the sampling temporary storage chamber 14 for processing.

[0029] When the waste liquid containing the magnetic material enters the second chamber 12, the waste liquid can be subjected to secondary treatment by the stirring device 4 in the second chamber 12, so that the magnetic material in the waste liquid can be subjected to secondary adsorption;

[0030] When the clean water containing the magnetic material enters the magnetic material recovery chamber 13, an external adsorption material containing a magnet can be used to adsorb the magnetic material in the clean water, for example, magnetite powder, which is a common magnetic mineral, has a large specific surface area after being made into powder, and can better contact and adsorb the magnetic material in the clean water containing the magnetic material; or a magnetic field can be added outside the magnetic material recovery chamber 13, and the adsorption of the magnetic material can be realized by the magnetic force of the magnetic field. After adsorption, the waste water in the magnetic material recovery chamber 13 is discharged, so that the collection process of the magnetic material is realized.

[0031] When the waste liquid containing the magnetic material enters the sampling temporary storage chamber 14, the waste liquid can be detected by the equipment in the sampling temporary storage chamber 14. In the detection, it can be checked whether the content of the magnetic material in the waste liquid exceeds the predetermined value, and if it exceeds the predetermined value, the magnetic material in the waste liquid needs to be continuously mixed and stirred.

[0032] Further, the detection equipment 15 can be arranged in the sampling storage room 14, and the detection equipment 15 is used to measure the content of the magnetic material in the waste liquid. It should be noted that the detection equipment 15 can be an electromagnetic induction type detection equipment 15.

[0033] That is, the principle of the electromagnetic induction type detection equipment 15 is based on the law of electromagnetic induction. When the waste liquid containing the magnetic material passes through a detection coil, the magnetic field changes, and then an induced electromotive force is generated in the coil. The equipment calculates the content of the magnetic material by measuring the size, frequency and other parameter changes of the induced electromotive force. If the waste liquid contains more magnetic material, the amplitude of the magnetic field change is large, and the induced signal is stronger.

[0034] Further, the water level detector 17 is arranged on the inner wall of the first chamber 2 and the second chamber 12. The water level detector 17 is used to detect the amount of waste liquid entering the first chamber 2 and the second chamber 12, so that the waste liquid does not overflow the chamber due to too much entering during stirring.

[0035] Further, the controller 16 and a plurality of button switches are arranged in the equipment main body 1. The controller 16 is electrically connected with the button switches, the electromagnet 3, the stirring device 4, the first electromagnetic valve 9 and the second electromagnetic valve 10. In use, the user can control the opening and closing of the electromagnet 3, the stirring device 4, the first electromagnetic valve 9 and the second electromagnetic valve 10 through the button switches and the controller 16, so as to facilitate the recycling of the waste liquid and the magnetic material.

[0036] Further, the reflux pipe 11 can be arranged between the second chamber 12 and the first chamber 2, and the suction pump for transporting the waste liquid is arranged at the reflux pipe 11. In use, the waste liquid in the second chamber 12 is introduced into the first chamber 2 for recycling through the suction pump. Meanwhile, the electromagnetic valve is arranged at the reflux pipe 11, so that the waste liquid can be introduced into the reflux pipe 11 through the electromagnetic valve.

[0037] Finally, it should be noted that the above examples are merely specific embodiments of the present application, and are used to illustrate the technical solutions of the present application, but not to limit the same. Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that any person skilled in the art can make modifications or easily think of changes to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to some of the technical features within the technical scope disclosed by the present application.
