DETAILED DESCRIPTION

[0016] The following is a detailed description of the specific implementation of the present invention with reference to the accompanying drawings.

[0017] Example:

[0018] The following is a specific embodiment of a small electromagnetic iron remover with self-cooling according to the present invention. Figure 1 、 Figure 2The machine mainly comprises a frame 1, mounted with a vibrating feeder 2. Below the vibrating feeder 2 is an iron removal tank 3, connected to a feed pipe 4 at the top and a discharge tee 5 at the bottom. Iron-containing material is automatically fed by the vibrating feeder 2 and falls into the iron removal tank 3 through the feed pipe 4. The screened iron-free material and iron impurities are then discharged through the discharge tee 5. A heat exchanger 6 is mounted on the iron removal tank 3 to cool it down.

[0019] Reference Figure 1 、 Figure 3 A material drop channel 301 is provided in the iron removal box 3. The top of the material drop channel 301 is connected to the feed pipe 4. The lower part of the material drop channel 301 has a contraction portion. The bottom end of the material drop channel 301 is connected to the discharge tee pipe 5. An iron remover 7 is provided in the material drop channel 301. The iron remover 7 is located near the contraction portion of the material drop channel 301.

[0020] The iron remover 7 includes a housing 701. The top plate of the housing 701 is tilted downward from the center to the sides, which can guide the material downward without accumulation. The bottom plate of the housing 701 is tilted upward from the center to the sides. The bottom plate can cooperate with the contraction of the material drop channel 301 to guide the material toward the iron remover 7 for better iron removal. The bottom plate of the housing 701 is provided with a recessed portion, which is a groove 12. There are several grooves 12, which are divided into two groups and are respectively arranged on two inclined sections of the bottom plate. The provision of the grooves 12 can accommodate a portion of iron impurities, preventing a large amount of accumulation on the surface of the iron remover 7 and causing channel blockage.

[0021] A cooling pipe 702 is provided within the housing 701. The cooling pipe 702 comprises a central tube 702a and two winding pipes 702b. The central tube 702a is hollowed out to form a flow channel 8. The two winding pipes 702b are connected to the left and right sides of the central tube 702a, respectively, and communicate with the flow channel 8 within the central tube 702a. The left winding pipe 702b is connected to the water inlet pipe 13, while the right winding pipe 702b is connected to the water outlet pipe 14. The water inlet pipe 13 and the water outlet pipe 14 are each threaded through the housing 701 and connected to the heat exchanger 6. Cooling water can flow from the water inlet pipe 13 into the left winding pipe 702b, into the flow channel 8 within the central tube 702a, and into the right winding pipe 702b. Cooling water then circulates through the water outlet pipe 14 to the heat exchanger 6, where it undergoes heat exchange.

[0022] A magnetic core 9 is installed in the central tube 702a, and an electromagnetic coil 10 is wound around the winding tube 702b. The large amount of heat generated by the iron remover 7 is absorbed by the cooling water to achieve cooling. The cooling water after absorbing the heat can be heat exchanged by the heat exchanger 6 and then circulated back to the cooling tube 702 for use.

[0023] The outer shell 701 of the iron remover 7 is also connected to heat dissipation fins 11. The fins 11 are multiple and are connected in two groups to two inclined sections of the top plate of the outer shell 701. Because the feed pipe 4, the material discharge channel 301, and the discharge tee 5 are connected to the outside world, the heat generated by the iron remover 7 during operation can be dissipated to the outside air through the heat dissipation fins 11, further reducing the temperature.

[0024] In addition, a three-way valve is provided in the discharge three-way pipe 5 for controlling the discharge of the iron-free material and iron impurities.

[0025] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications based on the spirit of the main technical solution of the present invention shall be included within the scope of protection of the present invention.
