[0002] The magnetic separator is mainly used for the wet type magnetic separation of magnetite and pyrrhotite with particle size below 3mm, and is a common separation device in ore dressing production. According to the difference of working medium, the magnetic separator can be divided into dry type and wet type. The dry type magnetic separator separates in the air, and is mainly used for selecting and separating large blocks, coarse particles and weak magnetic ores. The wet type magnetic separator separates in water or magnetic liquid, and is mainly used for selecting and separating fine particles and weak magnetic ores. In the production process, it is mainly applied to the post-milling process and the process before concentrate dewatering, and the main purpose is to separate or improve the material concentration.
[0003] When the wet type magnetic separator is in the normal range of ore supply, its separation index can basically remain normal. However, in daily production, the grinding, classification operation and belt ore supply in the upstream process of the magnetic separator will fluctuate, including the change of raw ore grade, which will cause the ore supply to the magnetic separator to suddenly increase in a short time, and when the capacity is exceeded, the ore will overflow from the rear side of the magnetic separator tank. The overflowed ore slurry will enter the magnetic tailings box along the rear side of the magnetic separator tank, which will seriously affect the separation index of the magnetic separator and cause the loss of useful minerals. In addition, the overflowed ore will cause poor ground hygiene on site, increasing the workload of workers. UTILITY MODEL CONTENTS

The lower side of the ore receiving box is provided with a discharge port, and the discharge port is connected with the concentrate box of the wet type magnetic separator through a pipeline.
[0006] As the improved technical scheme of the present application, the internal space of the ore receiving box is in inverted triangular structure, that is, the top of the ore receiving box has the largest opening.

[0017] The technical scheme of the present application is to manufacture a mine receiving box and connect a pipeline at one end of the mine receiving box. The pipeline outlet is led into the concentrate box of the wet magnetic separator, which can cope with the occurrence of the wet magnetic separator tank overflow phenomenon when the mine amount is suddenly large, and the overflowed mine is directly introduced into the concentrate box through the mine receiving box and the pipeline. The overflow of the wet magnetic separator directly into the concentrate box will reduce the quality of the concentrate to some extent. The magnetic separator suitable for this connection mode is mainly applied in the roughing, concentration magnetic separation before grinding, and concentration magnetic separation before filter dehydration in the magnetic separation process. Because there is a magnetic separation cleaning stage in the subsequent production process of roughing and concentration magnetic selection before grinding, the influence on the final concentrate grade is small. The concentration magnetic selection before filter dehydration mainly improves the concentration, and the material grade entering the magnetic separator has reached the standard. The feed of the last magnetic separator in the magnetic separation process is basically stable, so this device is not needed.
[0018] The technical scheme of the present application will be clearly and completely explained in combination with the specific embodiments.
[0019] As shown in Figures 1-4 A mine overflow receiving device of a wet magnetic separator, comprising a mine receiving box 1, the mine receiving box 1 is installed on the back side of the tank body of the wet magnetic separator 4 and can receive the overflow slurry of the tank body of the wet magnetic separator; the back side is the side of the tank body of the wet magnetic separator 4 close to the tailing box 5 of the wet magnetic separator 4; the lower side of the mine receiving box 1 is provided with a mine discharge port, and the mine discharge port is connected with the concentrate box 3 of the wet magnetic separator 4 through a pipeline 2.
[0020] As shown in Figure 1 The internal space of the mine receiving box 1 is in a reverse triangular structure, that is, the top of the mine receiving box 1 has the largest opening. In detail, the mine receiving box 1 has a length equal to the length of the tank body of the wet magnetic separator, and the side view is a triangle. The purpose of the triangle is to ensure that the bottom of the mine receiving box 1 can store a part of the mine, which plays a role in protecting the bottom of the mine receiving box 1 and preventing long-term slurry erosion.
[0021] In some embodiments, the ore receiving box 1 comprises a plane, an inclined plane and two side planes; the inclined plane is fixed to the bottom surface of the tank, and the plane and the inclined plane are connected from the bottom, i.e. to ensure that the interior of the ore receiving box is a triangular space; the plane extends to the space between the rear surface of the tank and the tailings box after being supported by the inclined plane, so as to ensure that the opening of the ore receiving box 1 is offset from the rear surface of the tank by a certain distance, facilitating the ore receiving box to receive all the overflowed ore slurry from the tank. The angle between the inclined plane and the plane is less than 90°; the two side planes are respectively located at the two ends of the space formed by the plane and the inclined plane, so that the ore receiving box finally has a triangular space with an open top. In actual application, the inclined plane of the ore receiving box 1 is tightly attached to the bottom surface of the tank of the wet magnetic separator 4 by welding, and the plane of the ore receiving box 1 is slightly higher than the inclined plane of the ore receiving box 1 by 10 cm, so that the ore receiving box 1 has a certain slope, facilitating the overflowed ore to flow by itself. In other embodiments, a slanted plate is placed inside the ore receiving box 1, one end of the slanted plate is arranged at the bottom of the ore receiving box 1 and located at the rear surface, so as to facilitate the ore receiving box 1 to form an inverted triangular space structure; the other end of the slanted plate is arranged at the top of the ore receiving box 1 and away from the rear surface.
[0022] In some embodiments, in order to facilitate the overflowed ore to flow by itself, the position of one end of the pipeline 2 located at the ore discharge opening is higher than the position of one end of the pipeline 2 located at the concentrate box 4 of the wet magnetic separator 3. Preferably, the height difference between the two ends of the pipeline 2 is 8-15 cm. More preferably, the height difference between the two ends of the pipeline 2 is 10 cm.
[0023] In order to ensure the stability of the installation, a flange interface is installed at the ore discharge opening, and the pipeline 2 is installed at the ore discharge opening through the flange interface.
