Description

Technical Field

[0001] This utility model relates to the field of magnetic coagulation technology, and in particular to an integrated magnetic coagulation sedimentation device. Background Technology

[0002] Magnetic coagulation is a novel water treatment process that organically combines traditional coagulation technology with magnetic technology. By adding magnetic particles or materials during the water treatment process, magnetic force is used to promote the aggregation and sedimentation of suspended solids, colloidal particles, and pollutants, thereby improving water treatment efficiency and purification effect. Magnetic coagulation technology has advantages such as short reaction time, small footprint, and stable and reliable effluent quality, and is widely used in sewage treatment, industrial wastewater treatment, and urban river management.

[0003] A search revealed that Chinese patent CN220098676U discloses an integrated magnetic coagulation and sedimentation device. By setting a magnetic block at the bottom of the turntable, magnetic powder can be attached to the turntable. The turntable rotates to the side away from the magnetic block and has a magnetic powder collection box, so that the separated turntable falls into the magnetic powder collection box below, thereby realizing the separation and recovery of magnetic powder in wastewater.

[0004] However, the above-mentioned device has the following drawbacks: it is difficult to achieve a balance between the magnetic powder adsorption layer on the rotating disc surface and the impact of the water flow, which easily leads to unstable adsorption; the magnetic powder does not completely detach when transitioning between the strong magnetic zone and the non-magnetic zone, resulting in residues; especially when treating high-concentration or viscous sludge, the magnetic powder is prone to caking and accumulating on the rotating disc surface, seriously affecting the separation efficiency and long-term operational stability of the system. Therefore, further improvements are needed. To this end, we propose an integrated magnetic coagulation sedimentation device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated magnetic coagulation sedimentation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an integrated magnetic coagulation sedimentation device, comprising a mixing tank and a sedimentation tank fixedly connected to the mixing tank, wherein a separation mechanism is provided on the right side of the sedimentation tank;

[0007] The separation mechanism includes two support seats, and a circular core column is fixedly connected between the two support seats. The circular core column has a drainage groove on its front outer wall, a water inlet groove on its rear outer wall, and a mud discharge groove on its top outer wall.

[0008] A connecting pipe is fixedly connected to the left outer wall of the single support on the left side, and the connecting pipe is fixedly connected to the sewage output pipe of the sedimentation tank and to the inlet tank.

[0009] A screw conveyor assembly is installed between the sludge discharge trough and the left-side support base;

[0010] The outer surface of the circular core is fitted with a sleeve, and the sleeve is rotatably connected to the two support seats in a sealed manner. A scraper is fixedly connected to the front side of the top opening of the mud discharge trough, and the scraper is in contact with the inner wall of the sleeve. A rotating assembly is installed between the sleeve and the single support seat on the right side.

[0011] The outer surface of the sleeve is uniformly and detachably fitted with multiple magnet components.

[0012] Furthermore, the right outer wall of the single support on the right side is fixedly connected to a sludge discharge pipe and a drain pipe, and the sludge discharge pipe is interconnected with the sludge discharge trough, and the drain pipe is interconnected with the drain trough. This arrangement realizes the separation and directional discharge of sludge and clean water.

[0013] Furthermore, the auger assembly includes an assembly base, which is disposed through an adjacent support base and is sealed and fixedly connected to the adjacent support base. A first motor is fixedly connected to the left side of the assembly base, and the drive end of the first motor is fixedly connected to the auger body. The assembly base is sealed and rotatably sleeved on the mounting shaft of the auger body. The outer wall of the auger body is in contact with the inner wall of the sludge discharge trough, which improves the reliability and efficiency of sludge discharge.

[0014] Furthermore, each of the two support seats is fixedly connected to a bearing seat on an adjacent side, and the inner ring of the bearing built into the bearing seat is fixedly sleeved on the outer surface of the sleeve. The bearing seat provides stable support for the sleeve, ensuring smooth rotation and good centering.

[0015] Furthermore, the rotating assembly includes a second motor, which is fixedly connected to an adjacent support base. The driving end of the second motor is fixedly connected to a drive gear, and the outer surface of the drive gear is meshed with a driven gear. The driven gear is fixedly sleeved on the outer surface of the sleeve. The gear transmission method ensures reliable power transmission and effectively controls the rotation speed of the sleeve.

[0016] Furthermore, each of the multiple magnet components includes a shielding base, which is embedded in the outer surface of the sleeve. The shielding base is fixed to the sleeve by several screws. An electromagnet is fixedly connected to the mounting end of the shielding base. The modular magnet components are easy to install, maintain and replace. The shielding base helps to concentrate the magnetic field and reduce magnetic leakage.

[0017] The beneficial effects of this utility model are:

[0018] In use, this invention employs a separation mechanism consisting of a circular core column and a rotating sleeve. The uniformly embedded magnetic components enhance the stability of magnetic field adsorption, preventing unstable adsorption caused by water flow impact.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-5 As shown, an integrated magnetic coagulation sedimentation device is disclosed, including a mixing tank 1 and a sedimentation tank 2 that is fixedly connected to the mixing tank 1. A separation mechanism is provided on the right side of the sedimentation tank 2. Both the mixing tank 1 and the sedimentation tank 2 are existing technologies. The principle of the integrated magnetic coagulation sedimentation device is disclosed in detail in Chinese Patent Publication No. CN220098676U.

[0029] The separation mechanism includes two support seats 6, with a circular core column 20 fixedly connected between them. The circular core column 20 has a drainage groove 18 on its front outer wall, a water inlet groove 17 on its rear outer wall, and a sludge discharge groove 16 on its top outer wall. A connecting pipe 9 is fixedly connected to the left outer wall of a single support seat 6 on the left side, and the connecting pipe 9 is fixedly interconnected with the sewage output pipe of the sedimentation tank 2 and the water inlet groove 17. A sludge discharge pipe 5 and a drain pipe 8 are fixedly connected to the right outer wall of a single support seat 6 on the right side, and the sludge discharge pipe 5 is interconnected with the sludge discharge groove 16, and the drain pipe 8 is interconnected with the drain groove 18. The fluid channels are cleverly integrated into a fixed component, realizing the sealing and interconnection between the rotating sleeve 21 and the fixed pipe. This is the core structure for realizing the "dynamic and static separation" function and simplifies the overall pipeline layout of the device.

[0030] A screw conveyor assembly is installed between the sludge discharge trough 16 and the left support seat 6. The screw conveyor assembly includes a mounting base 10, which passes through the adjacent support seat 6 and is sealed and fixedly connected to the adjacent support seat 6. A first motor 3 is fixedly connected to the left side of the mounting base 10. The drive end of the first motor 3 is fixedly connected to the screw conveyor body 14, and the mounting base 10 is sealed and rotatably sleeved on the mounting shaft of the screw conveyor body 14. The outer wall of the screw conveyor body 14 is in contact with the inner wall of the sludge discharge trough 16. The mounting base 10 is a mechanical seal support with a through hole. It passes through the left support seat 6 and is sealed and fixedly connected to it by a static seal (such as an O-ring or gasket). A rotary dynamic seal (such as a mechanical seal or stuffing box) is installed in its through hole for sealing and rotatably sleeved on the mounting shaft of the screw conveyor body 14.

[0031] A sleeve 21 is fitted on the outer surface of the circular core column 20, and the sleeve 21 is rotatably connected to the two support seats 6 in a sealed manner. The two ends of the sleeve 21 are sealed to the support seats 6 through mechanical seals. A bearing seat 13 is fixedly connected to the adjacent side of the two support seats 6, and the inner ring of the bearing built into the bearing seat 13 is fixedly fitted onto the outer surface of the sleeve 21. A scraper 15 is fixedly connected to the front side of the top opening of the mud discharge trough 16, and the scraper 15 is in contact with the inner wall of the sleeve 21. A rotating assembly is installed between the sleeve 21 and the single support seat 6 on the right. The rotating assembly includes a second motor 7, and the second motor 7 is fixedly connected to the adjacent support seat 6. A drive gear 12 is fixedly connected to the drive end of the second motor 7, and a driven gear 11 is meshed with the outer surface of the drive gear 12, and the driven gear 11 is fixedly fitted onto the outer surface of the sleeve 21.

[0032] Multiple magnet components are uniformly and detachably embedded on the outer surface of the sleeve 21. Each magnet component includes a shielding seat 4, which is embedded in the outer surface of the sleeve 21 and fixed to the sleeve 21 by several screws. An electromagnet 19 is fixedly connected to the mounting end of the shielding seat 4. The shielding seat 4 is a shell made of a soft magnetic material (such as low carbon steel). Its main functions are: first, to serve as a mounting base and physical protective cover for the electromagnet 19; and second, to utilize the high magnetic permeability of the soft magnetic material to form a "magnetic circuit shield," guiding the magnetic field generated by the electromagnet 19 to the inside of the sleeve 21.

[0033] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the various electrical components of this application to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

[0034] Working principle: After the sewage reacts in the mixing tank 1 and the sedimentation tank 2, the sewage containing magnetic powder is transported to the separation mechanism through the connecting pipe 9. The sewage enters the water inlet tank 17 on the rear side of the circular core column 20 through the connecting pipe 9 and flows into the annular separation space composed of the circular core column 20 and the sleeve 21.

[0035] The sleeve 21 rotates slowly and continuously under the drive of the rotating assembly (composed of a second motor 7, a driving gear 12, and a driven gear 11). Multiple electromagnets 19 fixed to its outer surface rotate accordingly, generating a rapidly changing magnetic field within the separation space. Magnetic flocs in the water are quickly attracted to the inner wall of the rotating sleeve 21 by the strong magnetic force generated by the electromagnets 19.

[0036] As the cylinder sleeve 21, which has adsorbed magnetic flocs, rotates, it gradually detaches from the liquid surface. The scraper 15, fixed to the top of the sludge discharge trough 16, fits tightly against the inner wall of the cylinder sleeve 21, scraping off the magnetic powder and sludge flocs adhering to its surface. The scraped-off sludge falls into the sludge discharge trough 16 below.

[0037] The concentrated sludge that falls into the sludge discharge trough 16 is transported to one side by the internal auger assembly (the first motor 3 drives the auger body 14), and finally discharged through the sludge discharge pipe 5 for subsequent magnetic powder recovery and sludge disposal.

[0038] Meanwhile, the separated clean water enters the internal drainage tank 18 and is discharged through the drain pipe 8.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
