Description

Technical Field

[0001] The invention relates to the technical field of magnetic separation equipment, and in particular to an air-blowing anti-blocking magnetic conductive module and a magnetic separator. Background Art

[0002] Magnetic separator is a professional equipment that uses magnetic field to effectively separate ferromagnetic and non-ferromagnetic components in minerals. It is widely used in mining, ceramics, chemical industry, food, resource recycling and other fields.

[0003] A magnetic separator that is widely used at present adopts such a structure: it includes a frame, on which is provided an annular electromagnetic device and a vertically arranged material pipeline, the annular electromagnetic device is sleeved outside the material pipeline, a magnetic conductive module is installed in the material pipeline, the magnetic conductive module includes a central axis, on which are installed multiple layers of magnetic conductive mesh, and the magnetic conductive mesh is provided with a plurality of mesh holes.

[0004] The working method of the magnetic separator is as follows: first, the annular electromagnetic device is energized to generate a magnetic field, the magnetic mesh is magnetized, and the material passes through the mesh holes on the magnetic mesh when flowing through the material pipeline, and the ferromagnetic components in the material are adsorbed onto the magnetic mesh; next, the power supply to the annular electromagnetic device is stopped, the magnetic mesh loses magnetism, and the ferromagnetic components adsorbed on the magnetic mesh fall off from the magnetic mesh, and the fallen material is effectively collected by negative pressure or vibration to become tailings.

[0005] The problem with this magnetic separator is that in order to more effectively adsorb the ferromagnetic components in the material, the mesh size of the magnetic mesh should be reduced as much as possible; however, too small a mesh size will reduce the material's permeability. In addition, for materials with poor fluidity, clogging is prone to occur during the magnetic separation process, resulting in an increase in tailings discharge, thereby causing waste of useful materials. Therefore, it is necessary to improve the magnetic separator and its magnetic conductive module to solve the problem that materials are easily blocked at the mesh size of the magnetic conductive mesh. Summary of the invention

[0006] The purpose of the present invention is to provide an air-blowing anti-blocking magnetic conductive module and a magnetic separator to solve the problem that materials are easily blocked at the mesh holes of the magnetic conductive mesh.

[0007] In order to achieve the above-mentioned purpose, the present invention discloses an air-blowing anti-blocking magnetic conductive module, which includes a vertically arranged central axis, a plurality of magnetic conductive meshes are installed on the central axis, the central axis passes through each magnetic conductive mesh in turn, an air flow channel with an air inlet is provided in the central axis, a flow gap is provided between some or all of the magnetic conductive meshes, and a plurality of air outlets are provided on the central axis that can at least distribute air flow to part of the flow gap, and the air outlets are connected to the air flow channel. The air-blowing anti-blocking magnetic conductive module can be installed in the material pipeline of the magnetic separator, and air flow can be introduced into the air flow channel, and the air flow enters the flow gap between the magnetic conductive meshes through the air outlets, and then passes through the mesh of the magnetic conductive mesh along with the material, thereby improving the passability of the material, avoiding the problem of material blockage during magnetic separation, thereby improving the efficiency of magnetic separation, and reducing the generation of tailings.

[0008] Furthermore, the portion above the first magnetic conductive mesh sheet on the central axis and the portion corresponding to each flow gap are provided with air outlet holes. With the above structure, airflow can be distributed from above each layer of magnetic conductive mesh sheet 2, and airflow passes through each layer of magnetic conductive mesh sheet 2 during magnetic separation, further improving the material passability.

[0009] Furthermore, the central axis is provided with a plurality of collars for spacing the magnetic conductive mesh sheets, and the collars are provided with exhaust holes connected to the exhaust holes. The collars can space the magnetic conductive mesh sheets to form a flow gap, and the exhaust holes on the collars play a role in guiding the airflow, and are used to guide the airflow into the flow gap.

The padding sleeve plays the role of padding the clamping nut; in addition, the head end of the central shaft can be designed to be longer, so as to facilitate the installation and fixation of the air-blowing anti-blocking magnetic module on the magnetic separator.

[0011] Furthermore, the air inlet of the airflow channel is arranged on the head end face of the central axis, the head of the central axis is screwed with a head connector, the head connector has an inner cavity connected to the air inlet of the airflow channel, an air inlet pipe connector for introducing airflow into its inner cavity is installed on the head connector, the end of the head connector away from the central axis is provided with a first conical positioning surface, and the end of the tail stopper away from the central axis is provided with a second conical positioning surface. After adopting the above structure, the head connector and the tail stopper are used to contact with the relevant parts or components on the magnetic separator to achieve the fixation of the air blowing anti-blocking magnetic conductive module. The first conical positioning surface and the second conical positioning surface are used to abut against the inner conical surface on the relevant parts or related components of the magnetic separator to achieve accurate positioning of the air blowing anti-blocking magnetic conductive module.

[0012] Furthermore, an inner ring groove is provided on the inner wall of the collar, and the inner ring groove is connected to the air outlet and the exhaust hole. After the inner ring groove is provided on the collar, the inner ring groove has the function of collecting airflow, and no matter how the inner ring groove rotates, it can ensure that the air outlet and the exhaust hole are connected, and the number of the air outlet and the exhaust hole can also be set arbitrarily.

[0013] Furthermore, the sleeve is provided with a plurality of exhaust holes, and the positions on the central axis corresponding to the inner ring groove of each sleeve are provided with a plurality of exhaust holes.

A first bracket is provided in the feed pipe, and a second bracket is installed in the material pipeline. The first bracket and the second bracket are spaced apart from each other. The first bracket and the second bracket are respectively provided with a first positioning sleeve and a second positioning sleeve, and the first positioning sleeve and the second positioning sleeve are respectively provided with a first inner cone surface and a second inner cone surface. The upper and lower ends of the air-blowing anti-blocking magnetic conductive module are respectively abutted against the first inner cone surface and the second inner cone surface of the first positioning sleeve and the second positioning sleeve. After adopting the above structure, the first bracket and the second bracket are used to fix the two ends of the air-blowing anti-blocking magnetic conductive module, and the first inner cone surface and the second inner cone surface on the first positioning sleeve and the second positioning sleeve are abutted against the first inner cone surface and the second inner cone surface on the air-blowing anti-blocking magnetic conductive module, thereby ensuring the accurate positioning of the central axis and realizing the precise installation of the air-blowing anti-blocking magnetic conductive module.

At the same time, it can also reduce the generation of tailings and reduce the waste of useful materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Continue to refer to Figure 7 , Figure 8 The magnetic separator further includes an air-blowing anti-blocking magnetic conductive module 200, which is installed in the main chamber of the material pipeline 18. The air-blowing anti-blocking magnetic conductive module 200 is used to replace the existing magnetic conductive module to solve the problem that the material is easily blocked at the mesh of the magnetic conductive mesh 2.

[0024] Figures 1 to 6 Some embodiments of the air-blowing anti-blocking magnetic conductive module 200 and the structures of the related parts of the air-blowing anti-blocking magnetic conductive module 200 in the embodiment are illustrated.

[0025] Reference Figures 1 to 4 In some embodiments of the air-blowing anti-blocking magnetic conductive module 200, the air-blowing anti-blocking magnetic conductive module includes a vertically arranged central axis 1, a plurality of magnetic conductive mesh sheets 2 are installed on the central axis 1, the central axis 1 passes through each magnetic conductive mesh sheet 2 in sequence, an air flow channel 3 with an air inlet is arranged in the central axis 1, a flow gap 4 is arranged between some or all of the magnetic conductive mesh sheets 2, and a plurality of air outlet holes 5 capable of distributing air flow to at least part of the flow gap 4 are arranged on the central axis 1, and the air outlet holes 5 are connected to the air flow channel 3. The "several air outlet holes 5 capable of distributing air flow to at least part of the flow gap 4 are arranged on the central axis 1" mentioned here includes at least the following situations: by arranging the air outlet holes 5 on the central axis 1, the air flow can be distributed to part of the flow gap 4, the air flow can be distributed to all of the flow gaps 4, and the air flow can be distributed to the flow gap 4 and above the first magnetic conductive mesh sheet 2.

[0026] Reference Figure 2In a preferred embodiment of the air-blowing anti-blocking magnetic conductive module 200, the number of the magnetic conductive meshes 2 is 29, which are divided into 8 layers. The 7 upper layers are each composed of 4 magnetic conductive meshes 2, and the bottom layer is a single magnetic conductive mesh 2. The number of flow gaps 4 is 7, so only some of the magnetic conductive meshes 2 have flow gaps 4; in other embodiments of the air-blowing anti-blocking magnetic conductive module, the magnetic conductive meshes 2 may also adopt other combinations, for example, each layer is a single magnetic conductive mesh 2, so that all the magnetic conductive meshes 2 are provided with flow gaps 4.

[0027] After the above improvements, the air-blowing anti-blocking magnetic module can be installed in the material pipeline of the magnetic separator for use. Air flow can be introduced into the air flow channel 3, and the air flow enters the flow gap 4 between the magnetic mesh 2 through the air outlet 5, and then passes through the mesh of the magnetic mesh 2 with the material, thereby improving the passability of the material, avoiding the problem of material blockage during magnetic separation, improving the efficiency of magnetic separation, and reducing the generation of tailings.

[0028] Reference Figure 2 , Figure 4 , Figure 5 In a preferred embodiment of the air-blowing anti-blocking magnetic conductive module 200, the portion above the first magnetic conductive mesh 2 on the central axis 1 and the portion corresponding to each flow gap 4 are provided with air outlet holes 5. In this way, airflow can be distributed from above each layer of magnetic conductive mesh 2, and airflow passes through each layer of magnetic conductive mesh 2 during magnetic separation, further improving the passability of the material.

[0029] Reference Figure 2 , Figure 3 , Figure 4 In some embodiments of the air-blowing anti-blocking magnetic conductive module 200, a plurality of collars 7 for spacing the magnetic conductive mesh sheets 2 are provided on the central axis 1, and exhaust holes 8 connected to the air outlet holes 5 are provided on the collars 7; the magnetic conductive mesh sheets 2 are spaced apart by the collars 7 to form a flow gap 4, and the exhaust holes 8 on the collars 7 have the function of guiding the airflow, and are used to guide the airflow into the flow gap 4.

[0030] Reference Figure 2 , Figure 3 , Figure 4In order to fix the magnetic mesh 2 and the collar 7 on the central shaft 1, in some embodiments of the air-blowing anti-blocking magnetic conductive module 200, a tail stopper 9 is provided at the tail of the central shaft 1, and collars 7 are provided at the position above the first magnetic mesh 2 and the position corresponding to each flow gap 4 on the central shaft 1. A clamping nut 10 for clamping the collar 7 and the magnetic mesh 2 is screwed on the central shaft 1. The tail stopper 9 and the clamping nut 10 work together to fix the magnetic mesh 2 and the collar 7 on the central shaft 1, and facilitate the assembly and disassembly of the magnetic mesh 2 and the collar 7. A padding sleeve 11 is provided between the clamping nut 10 and the closest collar 7 on the central shaft 1, and the padding sleeve 11 plays the role of padding the clamping nut 10; in addition, the head end of the central shaft 1 can also be designed to be longer, so as to facilitate the installation and fixation of the air-blowing anti-blocking magnetic conductive module on the magnetic separator.

[0031] Reference Figure 1 , Figure 2 In some embodiments of the air-blowing anti-blocking magnetic conductive module 200, the air inlet of the air flow channel 3 is arranged on the head end face of the central axis 1, the head of the central axis 1 is screwed with a head connector 12, the head connector 12 has an inner cavity connected to the air inlet of the air flow channel 3, and the head connector 12 is installed with an air inlet pipe connector 13 for introducing air flow into its inner cavity, and the end of the head connector 12 away from the central axis 1 is provided with a first conical positioning surface 14, and the end of the tail stopper 9 away from the central axis 1 is provided with a second conical positioning surface 15. The head connector 12 and the tail stopper 9 are used to abut against the relevant parts or components on the magnetic separator to achieve the fixation of the air-blowing anti-blocking magnetic conductive module 200. The first conical positioning surface 14 and the second conical positioning surface 15 are used to contact the inner conical surface on the relevant parts or relevant components of the magnetic separator to achieve accurate positioning of the air-blowing anti-blocking magnetic conductive module.

[0032] Reference Figure 6 In some embodiments of the air-blowing anti-blocking magnetic conductive module 200, an inner ring groove 16 is provided on the inner wall of the collar 7, and the inner ring groove 16 connects the air outlet 5 and the exhaust hole 8. After the inner ring groove 16 is provided on the collar 7, the inner ring groove 16 has the function of collecting airflow, and no matter how the inner ring groove 16 rotates, it can ensure that the air outlet 5 is connected with the exhaust hole 8, and the number of the air outlet 5 and the exhaust hole 8 can also be set arbitrarily.

[0033] Reference Figure 4 , Figure 5 , Figure 6In some embodiments of the air-blowing anti-blocking magnetic conductive module 200, a plurality of exhaust holes 8 are arranged on the collar 7, and a plurality of air outlet holes 5 are arranged on the central shaft 1 at positions corresponding to the inner ring groove 16 of each collar 7. Since a plurality of exhaust holes 8 are arranged on the collar 7, the air can be sprayed around the central shaft 1 through the air outlet holes 5 on the collar 7, so that the air flow can fully enter the flow gap 4 between the magnetic conductive mesh sheets 2, further improving the passability of the material; a plurality of air outlet holes 5 are arranged on the central shaft 1 corresponding to each collar 7, which is conducive to the discharge of the air flow in the air flow channel 3.

[0034] In some embodiments of the air-blowing anti-blocking magnetic conductive module 200, in addition to the spacing method of the collar 7, the formation of the flow gap 4 can also adopt other structural forms. For example, a heightened portion is provided at the edge or center hole of part or all of the magnetic conductive mesh sheets 2, and the heightened portion is used to space the magnetic conductive mesh sheets 2 to form the flow gap 4, thereby eliminating the collar 7 component, and the airflow can directly enter the flow gap 4 more smoothly through the airflow channel 3 and the air outlet 5.

[0035] Fig. 9 A structural form of a raised portion of the magnetic mesh 2 is specifically illustrated: the raised portion includes an outer cylinder 28 arranged at the edge of the magnetic mesh 2, an inner cylinder 29 arranged at the center hole of the magnetic mesh 2, and a plurality of spiral guide plates 30 connecting the outer cylinder 28 and the inner cylinder 29, and a portion of the inner cylinder 29 located between the spiral guide plates 30 is provided with an avoidance hole 31 for avoiding the air outlet 5. Fig. 9 The magnetic conductive mesh 2 shown is turned upside down for use. The advantage of adopting this structure is that the heightened portion formed by the outer cylinder 28, the inner cylinder 29, and the spiral guide plate 30 can separate the main body of the magnetic conductive mesh 2 from the next magnetic conductive mesh 2 to form a flow gap 4. The flow gap 4 is relatively closed by the outer cylinder 28 and the inner cylinder 29. The airflow coming out of the air outlet 5 can pass through the avoidance hole 31 and enter the space between the spiral guide plates 30, so that the airflow can be quickly diffused to the entire upper surface of the next magnetic conductive mesh 2, so that the material forms a spiral flow, which can further prevent the accumulation of materials and allow the materials to flow downward more smoothly through the mesh holes of the magnetic conductive mesh 2.

[0036] Reference Figure 7 , Figure 8 In order to install the air-blowing anti-blocking magnetic conductive module 200 on the magnetic separator, a detachable feed pipe 27 is installed at the upper end of the material pipeline 18, and the feed pipe 27 is used to pass the material into the material pipeline 18 through it.

[0037] A first bracket 21 is provided in the feed pipe 27, and a second bracket 22 is installed in the material pipeline 18. The first bracket 21 and the second bracket 22 are spaced apart from each other. A first positioning sleeve 23 and a second positioning sleeve 24 are provided on the first bracket 21 and the second bracket 22, respectively. A first inner conical surface 25 and a second inner conical surface 26 are provided on the first positioning sleeve 23 and the second positioning sleeve 24, respectively. The upper and lower ends of the air-blowing anti-blocking magnetic conductive module 200 abut against the first inner conical surface 25 and the second inner conical surface 26 of the first positioning sleeve 23 and the second positioning sleeve 24, respectively. The first bracket 21 and the second bracket 22 are used to fix the two ends of the air-blowing anti-blocking magnetic conductive module, and the first inner conical surface 25 and the second inner conical surface 26 on the first positioning sleeve 23 and the second positioning sleeve 24 abut against the first inner conical surface 25 and the second inner conical surface 26 on the air-blowing anti-blocking magnetic conductive module 200, thereby ensuring the accurate positioning of the central axis 1 and realizing the precise installation of the air-blowing anti-blocking magnetic conductive module 200. Figure 7 , Figure 8 In the shown embodiment, the feed pipe 27 is connected to the material pipeline 18 by a flange, and the flange connected to the feed pipe 27 and the flange connected to the material pipeline 18 are fixedly connected by bolts and nuts, so that the feed pipe 27 can be easily removed from the material pipeline 18. Since the first bracket 21 can be removed along with the feed pipe 27, the installation and replacement of the air blowing anti-blocking magnetic conductive module 200 is also relatively convenient.

[0038] The above is one installation method of the air-blowing anti-blocking magnetic conductive module 200. In other embodiments of the present invention, the air-blowing anti-blocking magnetic conductive module 200 can also be installed in other ways, for example, in one of the embodiments: a trumpet-shaped feed hopper with a larger diameter is provided at the upper feed end of the material pipeline 18, and the first bracket 21 is fixed to the inner wall of the trumpet-shaped feed hopper, thereby realizing the installation and fixation of the air-blowing anti-blocking magnetic conductive module 200 in the material pipeline 18.

When the material passes through the mesh of the magnetic mesh 2, the magnetic material in the material is adsorbed on the magnetic mesh 2, and the non-magnetic material in the material is able to pass through the mesh of the magnetic mesh 2 and then be discharged outward through the finished material outlet 20. During the magnetic separation process, the airflow is introduced into the airflow channel 3 through the air inlet pipe connector 13 on the head connector 12, and the airflow enters the inner ring groove 16 in the sleeve 7 through the air outlet 5, and flows to the flow gap 4 through the exhaust hole 8 provided on the sleeve 7, and then passes through the mesh of the magnetic mesh 2 with the material, thereby improving the passability of the material, avoiding the problem of material blockage during magnetic separation, improving the efficiency of magnetic separation, and reducing the generation of tailings.

[0040] Tailings discharge process: the three-way pipe is switched to a state where the tailings outlet 19 is connected to the material pipeline 18, the annular electromagnetic device 17 is powered off to eliminate the magnetic field, the magnetic conductive mesh 2 on the air-blowing anti-blocking magnetic conductive module 200 loses its magnetism, and the ferromagnetic components adsorbed on the magnetic conductive mesh 2 fall off and are finally discharged outward through the tailings outlet 19. In the tailings discharge process, airflow is introduced into the airflow channel 3 to assist the ferromagnetic components adsorbed by the magnetic conductive mesh 2 to fall off as soon as possible, so that the magnetic conductive mesh 2 can be restored to a clean state.
