Description

Technical Field

[0001] This utility model relates to the field of magnetic coagulation technology, specifically to a magnetic coagulation sedimentation tank. Background Technology

[0002] Magnetic coagulation sedimentation tank is a high-efficiency water treatment equipment that combines magnetic and coagulation sedimentation principles. Because the specific gravity of magnetic powder is five times that of water, the flocs formed by the magnetic powder will settle quickly, improving the efficiency of sewage treatment. When adding magnetic powder, there are two methods: dry powder addition and wet powder addition. However, because wet powder addition requires special magnetic powder dissolving and stirring equipment and storage tanks, the equipment is more complicated. Therefore, at present, the dry powder addition method is more commonly used.

[0003] Existing dry powder addition methods typically use equipment such as screw feeders to uniformly feed magnetic powder into wastewater in dry powder form. However, since the magnetic powder may have relatively poor dispersibility in water, it is impossible to guarantee that the magnetic powder is evenly distributed. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] In this technical solution, a magnetic coagulation sedimentation tank includes a sedimentation tank 1 and a screw feeder 2. A fixed frame 3 is installed on the side wall of the sedimentation tank 1, and the screw feeder 2 is installed on the upper wall of the fixed frame 3. The screw feeder 2 is electrically connected to an external power source. A magnetic powder storage tank 4 is installed at the input end of the screw feeder 2, and a spreading mechanism 5 is installed at the discharge end of the screw feeder 2.

[0022] The spreading mechanism 5 includes a connecting rod 51, a fixed plate 52, a rotating rod 53, a small fan 54, and a rotating ring 55. One end of the connecting rod 51 is installed on the lower wall of the discharge end of the screw feeder 2, and the other end of the connecting rod 51 is installed with the fixed plate 52. The rotating rod 53 is installed at the center of the upper wall of the fixed plate 52. The rotating ring 55 is sleeved on the outside of the rotating rod 53. The small fan 54 is installed on the side wall of the rotating ring 55 and is electrically connected to an external power source.

[0023] In this technical solution, the screw feeder 2 can transport the magnetic powder in the magnetic powder storage tank 4 to the discharge end and then fall onto the fixed plate 52. At this time, the small blower 54 can be started to blow out airflow, and the magnetic powder can be blown into the sedimentation tank 1 through the airflow, thereby expanding the spreading area of ​​the magnetic powder and making the magnetic powder more dispersed, thus improving the wastewater treatment efficiency.

[0024] Meanwhile, its small fan 54 is mounted on the rotating rod 53 via a rotating ring 55, and a bolt is screwed into the outer side of the rotating ring 55. The bolt passes through the side wall of the rotating ring 55 and fits against the side wall of the rotating rod 53. The two are in a linked state. At this time, the second motor 10 can drive the rotating rod 53 and the rotating ring 55 to rotate, so that its small fan 54 rotates on the fixed plate 52, further expanding the spreading area of ​​magnetic powder.

[0025] The small fan 54 selected in this paper can remotely adjust the wind speed. Remote control is achieved through the cooperation of a programmable logic controller (PLC) and sensors. The sensors collect relevant operating data and environmental parameters of the fan. The PLC controls the start, stop and speed adjustment of the fan according to the preset logic and the received signals to meet different working conditions.

[0026] In some technical solutions, a support frame 6 is installed on the side wall of the sedimentation tank 1, a first motor 7 is installed on the upper wall of the support frame 6, the first motor 7 is electrically connected to an external power source, and an agitator 8 is installed through the lower wall of the support frame 6 at the output end of the first motor 7. An agitator blade 9 is installed on the outer side wall of the agitator 8, and the agitator blade 9 is placed in the sedimentation tank 1.

[0027] In this technical solution, the first motor 7 drives the stirring rod 8 and the stirring blade 9 to rotate. The shear force and turbulence generated can break up the agglomerates of magnetic powder, so that the magnetic powder is evenly dispersed in the water in the form of individual particles or smaller agglomerates, avoiding magnetic powder sedimentation or excessively high local concentration, thereby ensuring the consistency of the magnetic powder's function in the entire water body.

[0028] At the same time, stirring can accelerate the mass transfer process between magnetic powder and water, as well as other substances in the water, enabling the magnetic powder to contact and interact with the target substances more quickly, improving the efficiency of the magnetic powder in the reaction or adsorption process, and helping to improve the treatment effect of the magnetic coagulation sedimentation tank.

[0029] In some technical solutions, a second motor 10 is installed at the center of the lower wall of the fixed disk 52. The second motor 10 is electrically connected to an external power source, and the output end of the second motor 10 passes through the upper wall of the fixed disk 52 and is connected to the rotating rod 53.

[0030] In this technical solution, the second motor 10 can drive the rotating rod 53 and the rotating ring 55 to rotate, so that its small fan 54 rotates on the fixed plate 52, further expanding the area of ​​magnetic powder spreading.

[0031] In some technical solutions, a conical sleeve 11 is installed on the upper wall of the rotating rod 53. The conical sleeve 11 is positioned above the small fan 54 and can shield the small fan 54.

[0032] In this technical solution, the conical sleeve 11 is positioned above the small fan 54. On the one hand, it prevents the magnetic powder from falling above the small fan 54 when it falls from the discharge end of the screw feeder 2. On the other hand, it guides the magnetic powder to fall in front of the output end of the small fan 54.

[0033] In some technical solutions, the magnetic powder storage tank 4 is filled with magnetic powder, and the side wall of the magnetic powder storage tank 4 is provided with a slot 12. A baffle plate 13 is inserted into the slot 12 and installed therein. The baffle plate 13 can block the discharge end of the magnetic powder storage tank 2.

[0034] In this technical solution, the opening size of the magnetic powder storage tank 4 can be adjusted by adjusting the baffle plate 13, thereby enabling adaptive adjustment of the magnetic powder feeding speed.

[0035] In some technical solutions, a sealing ring 14 is fitted to the inner side wall of the slot 12, and the sealing ring 14 can fit against the side wall of the baffle plate 13.

[0036] In this technical solution, the sealing ring 14 can prevent magnetic powder from leaking out from the gap between the slot 12 and the baffle plate 13.

[0037] Working principle: The screw feeder 2 can transport the magnetic powder in the magnetic powder storage tank 4 to the discharge end and then fall onto the fixed plate 52. At this time, the small fan 54 can be started to blow out airflow, which blows the magnetic powder into the sedimentation tank 1, thereby expanding the spreading area of ​​the magnetic powder and making the magnetic powder more dispersed, thus improving the wastewater treatment efficiency.

[0038] Meanwhile, its small fan 54 is mounted on the rotating rod 53 via a rotating ring 55, and a bolt is screwed into the outer side of the rotating ring 55. The bolt passes through the side wall of the rotating ring 55 and fits against the side wall of the rotating rod 53. The two are in a linked state. At this time, the second motor 10 can drive the rotating rod 53 and the rotating ring 55 to rotate, so that its small fan 54 rotates on the fixed plate 52, further expanding the spreading area of ​​magnetic powder.
