Description

Technical Field

[0001] This utility model relates to the field of magnetic coagulation technology, and in particular to a magnetic separator. Background Technology

[0002] Magnetic coagulation is a highly efficient water treatment process. It is an enhanced coagulation and sedimentation method formed by adding magnetic particles to traditional coagulation and sedimentation technology. Its basic principle is to add coagulants, flocculants, and magnetic particles to wastewater. The coagulant destabilizes suspended particles in the water, the flocculant promotes the aggregation of small particles into larger flocs, and the magnetic particles are adsorbed onto these flocs. In the magnetic coagulation process, a magnetic separator is used. Magnetic separation is a technology that uses the difference in magnetic properties of substances to separate them. Its basic principle is based on the fact that different substances experience different magnetic forces in a magnetic field. When a mixture containing magnetic and non-magnetic substances enters the magnetic field area of ​​the magnetic separator, the magnetic substances are attracted by the magnetic field, while the non-magnetic substances are not affected by the magnetic field, thereby achieving the separation of the two substances.

[0003] In daily work, it has been found that existing magnetic separators have problems such as large size, large footprint, slow processing speed, low efficiency, and small processing capacity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as large size, large footprint, slow processing speed, low efficiency, and small processing capacity, and to propose a magnetic separator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic separator, including a base, a housing mounted above the base, a magnetic cylinder and a magnetic core rotatably connected to the inner wall of the housing, the magnetic core being disposed within the inner wall of the magnetic cylinder, a high-speed shear machine mounted on one side of the housing, a water inlet on one side of the high-speed shear machine, a water outlet at the bottom of the housing, a magnetic powder outlet mounted on the side of the housing away from the high-speed shear machine, a speed reducer mounted on one side surface of the housing, sprockets mounted on the surfaces of the speed reducer and the magnetic cylinder respectively, a chain mounted on the surfaces of the two sprockets, a shovel plate mounted on the inner wall of the housing, and a fine-tuning component disposed between the base and the magnetic core.

[0006] Preferably, the magnetic core includes a magnetic core shaft rotatably connected to the outer shell, a plurality of magnetic blocks are mounted on the outer surface of the magnetic core shaft, and a partition is fixedly connected to the surface of the magnetic core shaft. Through the above components, the partition can separate the plurality of magnetic blocks on the magnetic core shaft, thereby facilitating the adsorption of magnetic powder with the magnetic cylinder.

[0007] Preferably, the partition is composed of multiple partition blocks 1 and partition blocks 2. By using multiple partition blocks 1 and partition blocks 2, the magnetic blocks can be placed separately, which facilitates subsequent disassembly and assembly.

[0008] Preferably, the fine-tuning assembly includes a connecting arm fixedly connected to the surface of the magnetic core shaft. A connecting member one is rotatably connected to the surface of the connecting arm, and a connecting member two is rotatably connected to the surface of the base. A screw one and a screw two are fixedly connected to the surfaces of the connecting member one and the connecting member two, and threaded sleeves are threadedly connected to the surfaces of the screw one and the screw two. Through the above components, during operation, rotating the threaded sleeves causes the screw one and the screw two to extend into the threaded sleeves. Subsequently, the connecting member one can drive the connecting arm to rotate, thereby fine-tuning the magnetic core.

[0009] Preferably, the first connector and the second connector are arranged in a U-shape.

[0010] Preferably, the magnetic block is made of high-quality strontium ferrite or a composite of high-performance rare-earth neodymium iron boron.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a magnetic separator, including a base 1, an outer shell 2 mounted on the top of the base 1, a magnetic cylinder 6 and a magnetic core 10 rotatably connected to the inner wall of the outer shell 2, the magnetic core 10 being disposed in the inner wall of the magnetic cylinder 6, a high shear machine 3 mounted on one side of the outer shell 2, a water inlet 4 disposed on one side of the high shear machine 3, a water outlet 9 disposed at the bottom of the outer shell 2, a magnetic powder outlet 8 disposed on the side of the outer shell 2 away from the high shear machine 3, a reducer 5 mounted on one side surface of the outer shell 2, sprockets 11 mounted on the surfaces of the reducer 5 and the magnetic cylinder 6 respectively, chains 12 mounted on the surfaces of the two sprockets 11, a shovel plate 7 mounted on the inner wall of the outer shell 2, and a fine-tuning component 13 disposed between the base 1 and the magnetic core 10.

[0023] In this embodiment, the high-shear mill 3 has a sludge separation and rotary cutting capacity of 0-20 m³ / h. The external material is entirely corrosion-resistant stainless steel, and the main mud-water contact parts are made of corrosion-resistant material. It employs a sealed cooling system with condenser pipes.

[0024] Specifically, the magnetic core 10 includes a magnetic core shaft 101 rotatably connected to the outer shell 2, a plurality of magnetic blocks 102 are mounted on the outer surface of the magnetic core shaft 101, and a partition 103 is fixedly connected to the surface of the magnetic core shaft 101.

[0025] In this embodiment, the partition 103 can separate the multiple magnetic blocks 102 on the magnetic core shaft 101, thereby facilitating the adsorption of magnetic powder with the magnetic cylinder 6.

[0026] Specifically, the partition 103 is composed of multiple partition blocks 1031 and partition blocks 1032. By using multiple partition blocks 1031 in conjunction with partition blocks 1032, the magnetic blocks 102 can be placed separately, which facilitates subsequent disassembly and assembly and can improve the magnetic field effect.

[0027] Specifically, the fine-tuning component 13 includes a connecting arm 136 fixedly connected to the surface of the magnetic core shaft 101. A connecting member 132 is rotatably connected to the surface of the connecting arm 136, and a connecting member 134 is rotatably connected to the surface of the base 1. A screw 133 and a screw 135 are fixedly connected to the surfaces of the connecting member 132 and the connecting member 134, respectively. A threaded sleeve 131 is threadedly connected to the surfaces of the screw 133 and the screw 135.

[0028] In this embodiment: During operation, the threaded sleeve 131 is rotated, so that screw 133 and screw 135 extend into the threaded sleeve 131. Then, connector 132 can drive connector arm 136 to rotate, thereby fine-tuning the magnetic core 10.

[0029] Specifically, connector 132 and connector 2134 are arranged in a U-shape.

[0030] Specifically, the magnetic block 102 is made of high-quality strontium ferrite or a composite of high-performance rare earth neodymium iron boron.

[0031] Working principle: In operation, the sludge is first separated and cut by the high-shear machine 3 through the inlet 4. The sludge then enters the machine body. The magnetic core shaft 101, together with multiple magnetic blocks 102 made of high-quality strontium ferrite or composite of high-performance rare earth neodymium iron boron, can adsorb magnetic powder onto the magnetic cylinder 6. The reducer 5, together with the sprocket 11 and chain 12, can drive the magnetic cylinder 6 to rotate. After the magnetic cylinder 6 drives the magnetic powder to a certain position, the shovel 7 in the machine body can scrape away the magnetic powder on the magnetic cylinder 6 and put it into the magnetic powder outlet 8 through the shovel 7. Finally, the liquid and sludge can be discharged through the drain outlet, thus achieving magnetic separation. Rotating the threaded sleeve 131 causes the screw 133 and screw 2 135 to extend into the threaded sleeve 131. Then, the connecting part 132 can drive the connecting arm 136 to rotate, so that the magnetic core 10 can be finely adjusted on the inner wall of the magnetic cylinder 6, thus completing the use.
