Technical Field
[0001] The utility model relates to the technical field of magnetic material recovery, in particular to a wet automatic magnetic separator. Background Art
[0002] The existing automatic magnetic separator includes a magnetic separation cavity, a feed pipe connected to the top of the magnetic separation cavity, and a discharge pipe connected to the bottom of the magnetic separation cavity. The magnetic flowing material flows through the feed pipe, the magnetic separation cavity, and the discharge pipe from top to bottom in sequence. Due to the fact that the magnetic flowing material has a relatively fast flow rate under the action of gravity, when flowing through the inside of the magnetic separation cavity, the impact force when the magnetic flowing material contacts the magnetic tube is too large, and the magnetic flowing material can only contact a part of the magnetic tubes directly below the feed pipe, so that the magnetic material is not easily adsorbed by the magnetic tube, resulting in a poor recovery effect of the magnetic material. Secondly, when discharging, after the magnetic rod in the magnetic tube is pulled out, some magnetic materials still remain above the magnetic tube, resulting in incomplete discharging. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a wet automatic magnetic separator. The wet automatic magnetic separator feeds from bottom to top, the magnetic flowing material has a relatively slow flow rate in the magnetic separation cavity, and the magnetic flowing material can contact all the magnetic tubes in the magnetic separation cavity, so that the recovery effect of the magnetic material is better; in addition, when discharging, a small amount of magnetic material remaining above the magnetic tube can be washed through the water inlet pipe, and complete discharging can be achieved.
[0004] To solve the above technical problem, the technical solution of the utility model is realized as follows:
[0005] A wet automatic magnetic separator includes a magnetic separation cavity fixed on a gantry and a magnetic rod device that can extend into or be pulled out of the magnetic separation cavity. The bottom of the magnetic separation cavity is connected with a feed pipe, and the top is connected with a discharge pipe.

[0007] Adopting the above scheme, the wet automatic magnetic separator feeds from bottom to top, the magnetic flowing material has a relatively slow flow rate in the magnetic separation cavity, and the magnetic flowing material can contact all the magnetic tubes in the magnetic separation cavity, so that the recovery effect of the magnetic material is better; in addition, when discharging, a small amount of magnetic material remaining above the magnetic tube can be washed through the water inlet pipe, and complete discharging can be achieved.
[0008] As a preferred embodiment of the wet automatic magnetic separator, there are two magnetic separation cavities in total. The two magnetic separation cavities are distributed on the same horizontal plane and are symmetric about the pipe orifices of the feed pipe, the discharge pipe, and the water inlet pipe.

Detailed implementation manners
[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0041] As Figures 1 to 6 shown, a wet automatic magnetic separator includes a magnetic separation cavity 2 fixed on a gantry 1 and a magnetic rod device that can extend into or withdraw from the magnetic separation cavity 2. A feed pipe 3 is connected to the bottom of the magnetic separation cavity 2, and a discharge pipe 4 is connected to the top. Magnetic flow material enters the magnetic separation cavity 2 through the feed pipe 3 and becomes non-magnetic flow material after demagnetization. The non-magnetic flow material is discharged through the discharge pipe 4.
[0042] A water inlet pipe 5 is also connected to the top of the magnetic separation cavity 2, and a magnetic discharge pipe 6 is connected to the bottom of the magnetic separation cavity 2. Clear water enters the magnetic separation cavity 2 through the water inlet pipe 5 to wash the adsorbed magnetic material and flows out through the magnetic discharge pipe 6.
[0043] This wet automatic magnetic separator feeds from bottom to top. The magnetic flow material has a slow flow rate in the magnetic separation cavity 2, and the magnetic flow material can contact all the magnetic tubes 14 in the magnetic separation cavity 2, making the recovery effect of the magnetic material better. In addition, when discharging, a small amount of magnetic material remaining above the magnetic tube 14 can be washed through the water inlet pipe 5, achieving complete discharging.
[0044] As Figures 1 to 3 shown, there are two magnetic separation cavities 2 in total. The two magnetic separation cavities 2 are distributed on the same horizontal plane and are symmetric about the nozzles of the feed pipe 3, the discharge pipe 4, and the water inlet pipe 5. To improve the working efficiency of the magnetic separator, one feed pipe 3 feeds materials into the two magnetic separation cavities 2 respectively, thereby improving the magnetic material recovery efficiency.
[0045] As Figures 1 to 3 shown, the water inlet pipe 5 is butt-connected and installed on the top of the discharge pipe 4. There are two discharge valve bodies 7 installed on the pipe body of the discharge pipe 4 to control the flow of non-magnetic flow material in the discharge pipe 4. There are two water inlet valve bodies 8 installed on the pipe body of the water inlet pipe 5 to control the flow of clear water in the water inlet pipe 5. To improve the integration of the entire device, the water inlet pipe 5 and the discharge pipe 4 are integrally installed. The flow of the discharge pipe 4 is controlled by the discharge valve body 7, and the flow of the water inlet pipe 5 is controlled by the water inlet valve body 8.
[0046] As Figure 1 shown, a pressure relief valve 9 is also installed on the pipe body of the water inlet pipe 5. To ensure the normal flow of the fluid in the pipe, by setting the pressure relief valve 9, the balance of the air pressure inside and outside the pipe is adjusted.
[0047] As Figures 1 to 3As shown, a return pipe 10 is also connected to the bottom of the magnetic separation cavity 2, and the flowing material in the magnetic separation cavity 2 is discharged through the return pipe 10. In order to discharge the excess magnetic fluid in the magnetic separation cavity 2, when the discharge pipe 4 is closed, the excess magnetic fluid in the magnetic separation cavity 2 is discharged from the return pipe 10 under the action of gravity.
[0048] As Figures 1 to 3 shown, the return pipe 10, the feed pipe 3, and the magnetic discharge pipe 6 are integrally installed together; a feed valve body 11 for controlling the flow of the magnetic flowing material in the feed pipe 3 is installed on the pipe body of the feed pipe 3; a return valve body 12 for controlling the flow of the magnetic flowing material in the return pipe 10 is installed on the pipe body of the return pipe 10; a magnetic discharge valve body 13 for controlling the flow of the magnetic material in the magnetic discharge pipe 6 is installed on the pipe body of the magnetic discharge pipe 6. In order to improve the integration of the entire device, the return pipe 10, the feed pipe 3, and the magnetic discharge pipe 6 are integrally installed together. The flow of the feed pipe 3 is controlled by the feed valve body 11, the flow of the return pipe 10 is controlled by the return valve body 12, and the flow of the magnetic discharge pipe 6 is controlled by the magnetic discharge valve body 13.
[0049] As Figures 4 to 6 shown, the magnetic rod device includes a magnetic tube 14 fixed in the magnetic separation cavity 2 and a magnetic rod 15 movably installed in the magnetic tube 14. The magnetic rod 15 can be driven by a cylinder 16 fixed on the outer side wall of the magnetic separation cavity 2 to extend or retract along the length direction of the magnetic tube 14; the magnetic tubes 14 are arranged horizontally at intervals, and the magnetic tubes 14 on the upper and lower adjacent horizontal planes are arranged staggeredly up and down. In order to realize the recovery of the magnetic material, when the cylinder 16 drives the magnetic rod 15 to extend into the magnetic tube 14, the magnetic tube 14 is magnetic at this time. When the magnetic fluid passes through the magnetic tube 14, it will be adsorbed by the magnetic tube 14. Then, after the cylinder 16 drives the magnetic rod 15 to withdraw from the magnetic tube 14, the magnetic tube 14 loses its magnetism at this time, and then the magnetic material will fall down.
[0050] As Figures 4 to 6 shown, an ultrasonic cleaner 17 extending into the magnetic separation cavity 2 is also installed on the outer side wall of the magnetic separation cavity 2. In order to avoid material accumulation at the corners in the magnetic separation cavity 2, when the magnetic separation cavity 2 is cleaned with clean water, the clean water remains in the magnetic separation cavity 2 for a certain period of time, and the ultrasonic cleaner 17 vibrates to clean the inside of the magnetic separation cavity 2, so as to keep the inside of the magnetic separation cavity 2 clean.
[0051] The working principle of the present utility model:
[0052] S1. Only the feed valve body 11 and the discharge valve body 7 are opened, and the rest of the valve bodies are all closed; the magnetic fluid is fed from bottom to top through the feed pipe 3. The flow rate of the magnetic fluid in the magnetic separation cavity 2 is slow, and the magnetic flowing material can contact all the magnetic tubes 14 in the magnetic separation cavity 2. At this time, the magnetic rod 15 extends into the magnetic tube 14, and the magnetic tube 14 is magnetic. When the magnetic fluid passes through the magnetic tube 14, it will be adsorbed by the magnetic tube 14. The remaining non-magnetic fluid is discharged from the discharge pipe 4. AsFigure 7 as shown
[0053] S2. Only open the return material valve body 12 and close all other valve bodies. When the valve bodies are closed, there will be magneto-fluid remaining in the magnetic separation cavity 2 at this time. After opening the return material valve body 12, the excess magneto-fluid in the magnetic separation cavity 2 is discharged from the return pipe 10 under the action of gravity, and only the magnetic material adsorbed on the magnetic tube 14 remains, as Figure 8 shown
[0054] S3. Withdraw the magnetic rod 15 from the magnetic tube 14 through the cylinder 16. At this time, the magnetic tube 14 loses its magnetism, and then the magnetic material will fall. Subsequently, open the water inlet valve body 8 and close all other valve bodies. After the clean water enters from the water inlet pipe 5, it can wash a small part of the magnetic material remaining above the magnetic tube 14. After flushing for a period of time, close the water inlet valve body 8 and let the clean water remain in the magnetic separation cavity 2 for a period of time, as Figure 9 shown
[0055] S4. Start the ultrasonic cleaner 17. By vibrating and cleaning the inside of the magnetic separation cavity 2 with the ultrasonic cleaner 17, the accumulated material at the corners in the magnetic separation cavity 2 can be removed. Subsequently, close the ultrasonic cleaner 17 and open the magnetic discharge valve body 13. The magnetic material is discharged from the magnetic discharge pipe 6 together with the water, as Figure 10 shown
[0056] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
