[0026] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0027] like Figure 1 - Figure 3 As shown, a pulp impurity cleaning device comprises: an equipment frame 1, a magnetic suction stirring tank 2 is arranged on the equipment frame 1, a clamp 5 is arranged between the magnetic suction stirring tank 2 and the equipment frame 1, the clamp 5 is sleeved on the outside of the magnetic suction stirring tank 2, the clamp 5 is threadedly connected to the equipment frame 1, a feed pipe 3 is arranged at the upper end of the magnetic suction stirring tank 2, and a discharge pipe 4 is arranged at the lower end of the magnetic suction stirring tank 2;

[0028] The upper end of the magnetic stirring tank 2 is also fixedly connected to a stirring motor 6, and a stirring magnetic component is arranged inside the magnetic stirring tank 2. The output end of the stirring motor 6 extends to the interior of the magnetic stirring tank 2 and is fixedly connected to the stirring magnetic component. The stirring magnetic component includes a stirring vertical rod 13, and a magnetic stirring rod 10 is arranged on the stirring vertical rod 13. The lower end of the magnetic stirring tank 2 is fixedly connected to a conical discharge tank 7, and the stirring magnetic component extends to the interior of the conical discharge tank 7. A discharge filter component 8 is arranged at the lower end of the conical discharge tank 7.

[0029] The pulp enters the magnetic stirring tank 2 from the feed pipe 3, the stirring motor 6 is started to drive the stirring rod 13 to rotate, and the stirring rod 13 drives the magnetic stirring rod 10 to stir the pulp, so that the magnetic stirring rod 10 is in full contact with the pulp. When the magnetic stirring rod 10 is powered on, the magnetic stirring rod 10 magnetically attracts the metal in the pulp through electromagnetic induction, so that the metal impurities in the pulp are adsorbed on the magnetic stirring rod 10, and the fully stirred pulp is discharged through the discharge pipe 4. At this time, the magnetic stirring rod 10 is powered off, the magnetic stirring rod 10 loses its magnetism, and the metal particles adsorbed on the magnetic stirring rod 10 fall onto the magnetic filter 17 due to gravity.

[0030] Refer to the attached Figure 4 A built-in electric connecting rod 12 is provided inside the magnetic stirring rod 10, and the built-in electric connecting rod 12 is electrically connected to the inside of the stirring rod 13. A magnetic coil 11 is wound on the built-in electric connecting rod 12, one end of the magnetic coil 11 is electrically connected to an end of the built-in electric connecting rod 12 away from the stirring rod 13, and the other end of the magnetic coil 11 is electrically connected to the inside of the stirring rod 13.

[0031] According to the above structure, a power line with positive and negative electrodes is arranged inside the stirring rod 13. The current flows through the positive electrode inside the stirring rod 13, flows through the built-in electric connecting rod 12, reaches the end of the built-in electric connecting rod 12 away from the stirring rod 13, and is connected to one end of the magnetic attraction coil 11. The other end of the magnetic attraction coil 11 is connected to the negative power line of the stirring rod 13.

[0032] Refer to the attached Figure 3 The number of the magnetic stirring rods 10 is multiple, and the length of the magnetic stirring rods 10 is adapted to the direct connection between the magnetic stirring tank 2 and the conical discharge tank 7.

[0033] According to the above structure, the length of the magnetic stirring rod 10 in the magnetic stirring tank 2 is different from that in the conical discharge tank 7, which can fully stir the pulp. At the same time, the conical design of the conical discharge tank 7 facilitates the discharge of pulp.

[0034] Refer to the attached Figure 5 The discharge filter assembly 8 includes a discharge valve 9 and a magnetic filter assembly. A magnetic filter assembly is arranged on the top of the discharge valve 9, and the magnetic filter assembly is plug-connected to the discharge valve 9.

[0035] According to the above structure, the discharge valve 9 is used to control the discharge of pulp, and the magnetic filter assembly is used for the final filtration during discharge and the collection of metal impurities dropped from the magnetic stirring rod 10 after power failure.

[0036] Refer to the attached Figure 3 and Figure 5 A stirring inclined plate 14 is fixedly connected to the stirring upright rod 13 at an upper position corresponding to the magnetic filter assembly.

[0037] According to the above structure, the stirring blade 14 is designed to be placed obliquely. When rotating, it can push the pulp at the bottom upward to make the stirring of the pulp more three-dimensional. At the same time, it can scratch the magnetic filter 17 when discharging the pulp to prevent the magnetic filter 17 from being blocked by pulp fibers.

[0038] Refer to the attached Figure 3 - Figure 6 The magnetic filter assembly includes a filter plate 15, one end of the filter plate 15 located below the conical discharge tank 7 is fixedly connected to a magnetic filter 17, a sealing rubber ring 18 is provided on the outside of the magnetic filter 17, and a ring-shaped sealing strip 19 is fixedly connected to the part of the filter plate 15 located at the discharge valve 9.

[0039] According to the above structure, the magnetic filter 17 is made of permanent magnet material and can magnetically attract passing metal. The annular sealing strip 19 is used for positioning the magnetic filter assembly during insertion and can also increase the sealing effect. The sealing rubber ring 18 is used for contact sealing between the magnetic filter assembly and the conical discharge tank 7.

[0040] Refer to the attached Figure 6 A filter buckle 16 is fixedly connected to one side of the filter plate 15 away from the magnetic filter screen 17 .

[0041] According to the above structure, the filter buckle 16 is used to facilitate the removal of the magnetic filter assembly from the discharge valve 9.

[0042] The working principle of the utility model is as follows: pulp enters the magnetic attraction stirring tank 2 from the feed pipe 3, the stirring motor 6 is started to drive the stirring rod 13 to rotate, the stirring rod 13 drives the magnetic attraction stirring rod 10 to stir the pulp, so that the magnetic attraction stirring rod 10 is in full contact with the pulp, when the magnetic attraction stirring rod 10 is energized, the magnetic attraction stirring rod 10 magnetically attracts the metal in the pulp through electromagnetic induction, so that the metal impurities in the pulp are adsorbed on the magnetic attraction stirring rod 10, and the fully stirred pulp is discharged through the discharge pipe 4.

[0043] At this time, the power to the magnetic stirring rod 10 is cut off, and the magnetic stirring rod 10 loses its magnetism. The metal particles adsorbed on the magnetic stirring rod 10 fall onto the magnetic filter 17 due to gravity, and the magnetic filter 17 collects them. After the collection is completed, the magnetic filter assembly is pulled out by pulling the filter buckle 16 to clean the metal impurities on the magnetic filter 17.

[0044] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
