Description

Technical Field

[0001] The invention relates to a magnetic separation device in the field of water treatment, in particular to a horizontal rotating ring high gradient magnetic separation machine. Background Art

[0002] High gradient magnetic separators are divided into periodic high gradient magnetic separators and continuous high gradient magnetic separators. Periodic high gradient magnetic separators are used in the field of sewage treatment and are one of the commonly used water treatment magnetic separation equipment.

[0003] In recent years, with the development of my country's industry, more and more industrial wastewater has been generated, and the content of suspended matter and metal ions in the wastewater has also increased. The treatment of this wastewater adopts conventional periodic high-gradient magnetic separators. Due to the limited effective working hours, the processing capacity is limited. Therefore, there is an urgent need for a new type of high-gradient magnetic separator with large processing capacity and continuous operation.

[0004] Chinese patent CN111151376A discloses "a composite magnetic system for a flat ring high gradient magnetic separator", which can be applied to a flat ring high gradient magnetic separator, and includes a rotating ring driven by a power mechanism, whose rotation axis extends in the up-down direction, and the outer periphery of the rotating ring is fixed with four circumferentially spaced permanent magnetic poles, namely inner magnetic poles, and the outer periphery of the permanent magnetic poles is fixed with a cylinder, and the outer periphery of the cylinder is fixed with a magnetic concentrating medium. The composite magnetic system also includes four circumferentially spaced electromagnetic magnetic poles, namely outer magnetic poles, located on the periphery of the magnetic concentrating medium.

[0005] When in use, the rotating ring rotates under the drive of the power mechanism. When the permanent magnetic pole rotates to the position corresponding to the electromagnetic pole, a horizontal magnetic field is generated between the permanent magnetic pole and the electromagnetic pole. The space where the horizontal magnetic field is located forms a sorting space. The magnetic medium in the sorting space is magnetized and can absorb the corresponding metal impurities. The existing problem of this composite magnetic system is that the permanent magnetic pole rotates with the rotating ring, so the magnetic field generated between the permanent magnetic pole and the electromagnetic pole is variable. The variable magnetic field is not conducive to the stable magnetization of the magnetic medium, nor is it conducive to the deep removal of fine suspended matter and metal ions. Due to the uncertainty of the magnetic field boundary, it is not conducive to the slag unloading operation. In addition, in the sorting space, it is not easy to generate a gradient magnetic field on the magnetic medium box, which is not conducive to the treatment of wastewater, because the types, content, particle size, types and amount of suspended matter in the wastewater are complicated.

[0027] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] An embodiment of a horizontal rotating ring high gradient magnetic separation separator of the present invention is as follows: Figures 1 to 6 As shown:

[0030] The machine frame includes an upper frame 14 and a lower frame 22. The upper frame 14 is rotatably equipped with a transmission main shaft 16 whose rotation axis extends in the up-down direction. The upper frame is also provided with a swivel driving mechanism for driving the transmission main shaft to rotate. The swivel driving mechanism includes a motor and a reducer 15. The motor is connected to the reducer 15. The power output end of the reducer 15 is connected to the transmission main shaft 16.

[0031] A rotating ring 9 is fixed on the transmission main shaft 16, and a magnetic medium box 21 is fixed on the outer periphery of the rotating ring 9. Because the rotating ring is arranged horizontally, the rotating ring can also be a horizontal rotating ring. An inner magnetic pole 26 located on the inner side of the magnetic medium box and an outer magnetic pole located on the outer side of the magnetic medium box are fixed on the lower end frame. The outer magnetic pole includes a left outer magnetic pole 212 and a right outer magnetic pole 211 arranged symmetrically with the left outer magnetic pole. The left outer magnetic pole 212 and the right outer magnetic pole 211 are C-shaped structures arranged with openings opposite to each other. The circumferential ends of the right outer magnetic pole respectively constitute the first outer magnetic pole 2 and the second outer magnetic pole 6, and the circumferential ends of the left outer magnetic pole respectively constitute the third outer magnetic pole 11 and the fourth outer magnetic pole 18. The ends of the first outer magnetic pole 2, the second outer magnetic pole 6, the third outer magnetic pole 11 and the fourth outer magnetic pole 18 are all fixed with outer magnetic pole heads 28. That is to say, in the present invention, four outer magnetic pole heads arranged in sequence along the circumferential direction are fixed on the outer magnetic pole. An excitation coil is disposed on the periphery of each outer magnetic pole head. In this embodiment, the excitation coils on the periphery of each outer magnetic pole head are respectively referred to as the first excitation coil 1, the second excitation coil 5, the third excitation coil 10 and the fourth excitation coil 17.

[0032] The inner magnetic pole 26 is a cylindrical structure with truncated head 34 planes on the front and rear sides, and a center hole 29 is opened in the center of the inner magnetic pole. The inner magnetic pole on the left side of the center hole 29 is called the left inner magnetic pole 262, and the inner magnetic pole on the right side of the center hole is called the right inner magnetic pole 261. The left outer peripheral surface of the left inner magnetic pole 262 and the right outer peripheral surface of the right inner magnetic pole 261 are both arc-shaped surfaces. The left side of the left inner magnetic pole 262 is fixed with a third inner magnetic pole head 32 and a fourth inner magnetic pole head 33 with an arc-shaped structure, and the right side of the right inner magnetic pole 261 is fixed with a first inner magnetic pole head 27 and a second inner magnetic pole head 31 with an arc-shaped structure, wherein the third inner magnetic pole head 32 and the fourth inner magnetic pole head 33 are integrally arranged, and the first inner magnetic pole head 27 and the second inner magnetic pole head 31 are integrally arranged. Along the radial direction of the inner magnetic pole, the outer circumference of each inner magnetic pole head is arranged in parallel with the inner circumference of the corresponding outer magnetic pole head at intervals, and the relative side surfaces of each inner magnetic pole head and the corresponding outer magnetic pole head are both arc-shaped surfaces arranged coaxially with the transmission main shaft, and an arc-shaped sorting space 30 is formed between each inner magnetic pole head and the corresponding outer magnetic pole head, and the sorting space is arranged horizontally.

[0033] In this embodiment, each sorting space is composed of an upper sorting space 38 and a lower sorting space 39. The width of the upper sorting space in the inner-outer direction is greater than the width of the lower sorting space in the inner-outer direction. The specific implementation means is: the upper side of the inner end of the corresponding outer magnetic pole head has an inward-concave step, so that the upper end of the outer magnetic pole head is farther away from the corresponding inner magnetic pole head.

[0034] The rotating ring 9 and the magnetic medium box on the rotating ring span the sorting spaces in the circumferential direction. A downward water supply port is arranged on the upper side of the magnetic medium box corresponding to the sorting space on the frame. Since there are four sorting spaces in this embodiment, there are also four water supply ports, which are respectively called the first water supply port 3, the second water supply port 7, the third water supply port and the fourth water supply port 19. A flushing water tank for flushing the magnetic medium box is arranged on the frame downstream of the corresponding sorting space. Similarly, since there are four sorting spaces in this embodiment, there are also four flushing water tanks, which are respectively the first flushing water tank 4, the second flushing water tank 8, the third flushing water tank and the fourth flushing water tank 20.

[0035] In this embodiment, the rotating ring includes an upper ring, a lower ring and a partition sleeve connected between the upper ring and the lower ring, the magnetic medium box is fixed to the outer periphery of the partition sleeve, the magnetic medium box includes a medium plate 37 connected to the partition sleeve, a horizontally arranged steel bar 36 is fixed on the medium plate 37, the plate thickness extension direction of the medium plate 37 is consistent with the extension direction of the steel bar length, and from top to bottom, the diameter of the steel bar on the lower side is smaller than the diameter of the steel bar on the upper side. Specifically, the magnetic medium box in this embodiment includes an upper magnetic medium box 40 corresponding to the upper separation space and a lower magnetic medium box 41 corresponding to the lower separation space, the upper magnetic medium box includes an upper medium plate, an upper steel bar group 42 is fixed on the upper medium plate, and a lower steel bar group 42 is fixed on the lower medium plate, and the upper steel bar group and the lower steel bar group both include a plurality of the steel bars arranged at intervals. The upper medium plate and the lower medium plate together constitute the medium plate of the magnetic medium box, and the axis of the steel bar is parallel to the tangent direction of the rotating ring.

[0036] The inner and outer width of the lower medium box is smaller than that of the upper medium box, that is, the inner and outer width of the lower steel rod group is smaller than that of the upper steel rod group. The diameter of the steel rods in the upper steel rod group is larger than that of the steel rods in the lower steel rod group, which helps to form a gradient magnetic field in the sorting space. The steel rods in the sorting space form a gradient adsorption capacity, and the suspended matter of different particle sizes is removed in layers, resulting in a better sorting effect. In other embodiments of the present invention, the spacing between adjacent steel rods in the lower steel rod group can also be smaller than the spacing between adjacent steel rods in the upper steel rod group.

[0037] The upper ring and the lower ring are hollowed out to allow corresponding water flow to pass through, and water holes for water flow to pass through are opened on the upper ring and the lower ring.

[0038] A right clean water outlet 23 is provided at the bottom of the two sorting spaces on the right, and a left clean water outlet 24 is provided at the bottom of the two sorting spaces on the left. The water flowing out through the left clean water outlet 24 and the right clean water outlet 23 is used as the clean water product, and the sludge residue on the medium box rinsed by each rinse sink will be collected at the lower side of the rotating ring and discharged from the sludge residue outlet.

[0039] In this embodiment, the thickness of the medium box along the magnetic force line direction, i.e., the radial direction of the rotating ring, is between 40 and 250 mm, and the height of the medium box is between 150 and 2500 mm. The magnetic field strength of the sorting space is not less than 1.0 T. The rotating speed of the rotating ring is between 1 and 18 rpm.

[0040] An "O"-shaped magnetic circuit is formed between the left inner magnetic pole and the left outer magnetic pole, and an "O"-shaped magnetic circuit is formed between the right inner magnetic pole and the right outer magnetic pole. When in use, a horizontal magnetic field is formed between each outer magnetic pole head and the corresponding inner magnetic pole head, and the rotating ring rotates horizontally with the magnetic medium box. When the magnetic medium box enters the sorting space, the steel rod is magnetized, and the wastewater flows from top to bottom through the corresponding water supply port. The wastewater passes through the water holes on the upper ring, and then flows through the array steel rods of the magnetic medium box. After being adsorbed by the steel rods, it becomes clean water, and then flows out through the water holes on the lower ring and the corresponding clean water outlet. The magnetic medium box adsorbed with metal impurities rotates to the flushing sink position. At this time, the magnetic medium box has been rotated out of the sorting space, and the steel rod is no longer magnetic. The impurities on the steel rod can be easily washed away through the flushing sink. The sludge residue obtained through the flushing sink is collected by the sludge residue outlet.

[0041] The magnetic field lines of the sorting space are in the horizontal direction, and the water supply direction is perpendicular to the magnetic lines of force. When the pre-treated wastewater passes through the sorting space, it is adsorbed on the medium rods in the medium box to achieve solid-liquid separation and obtain clean water. The upper end to the lower end of the medium box is composed of steel rods with different rod diameters distributed from coarse to fine. Different gradient magnetic fields will be generated under the stimulation of the background magnetic field, and suspended particles of different particle sizes will be effectively adsorbed.
