Description

Technical Field

[0001] The utility model relates to a magnetic separation device, in particular to a rotary magnetic separation device for sewage treatment. Background Art

[0002] In the mining operations of coal enterprises, a large amount of wastewater is generated. The composition of these mine wastewaters is relatively simple, and the main pollutants include suspended matter, wood decay in waste pits, human excrement, and a small amount of waste oil and emulsified oil. The treatment of this type of wastewater has significant reuse value, and the core of the treatment is to effectively remove suspended matter in the water. In addition, the treatment process of domestic sewage and polluted rivers, lakes and other water bodies also faces the problem of high suspended matter content. In order to cope with the above problems, a variety of sewage treatment equipment has been developed, hoping to efficiently remove suspended matter in sewage.

[0003] Magnetic separation technology has shown unique advantages in sewage treatment. It can not only effectively remove suspended matter, but also reduce the content of pollutants such as biochemical oxygen demand and total phosphorus in sewage to a small extent. Therefore, at the technical research level, magnetic separation purification technology has been introduced into the field of sewage treatment. However, the current magnetic technology sewage treatment equipment on the market (such as super magnetic equipment) can only meet the basic needs of daily sewage treatment in terms of treatment capacity. In addition, the initial investment cost of super magnetic equipment is high, and the subsequent maintenance costs are also relatively expensive, resulting in poor economic benefits and the need to improve operational stability. These factors limit its widespread application in the market. Therefore, technical improvement and optimization of magnetic technology sewage treatment equipment is an issue that needs to be urgently addressed. Utility Model Content

[0004] In order to solve the deficiencies existing in the above-mentioned technologies, the utility model provides a rotary magnetic separation device for sewage treatment.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: comprising an equipment body with an inner cavity, a water inlet and a water outlet are respectively opened on two mutually corresponding sides of the equipment body, and a mud suction mechanism is provided in the cavity of the equipment body;

[0006] The mud suction mechanism includes a plum blossom wheel and a transmission chain meshing with the plum blossom wheel, and the outer ring of the transmission chain is arranged with a plurality of U-shaped magnetic grooves equipped with bar magnetic bars;

[0007] A sludge collecting mechanism is provided on the water outlet side of the sludge suction mechanism. The sludge collecting mechanism includes a sludge collecting trough. The sludge collecting trough is in frictional contact with the outer surface of the bar magnetic bar through a sludge scraper. The sludge collecting trough is connected to the sludge discharge port through a pipe connected to both sides of the equipment body.

[0008] Furthermore, there are two sets of mud suction mechanisms, which are spaced apart in the inner cavity of the equipment body, and each set of mud suction mechanisms is equipped with a set of sludge collection mechanism on one side of the water outlet direction.

[0009] Furthermore, a water distribution plate is provided on the water inlet side of the mud suction mechanism. Each mud suction mechanism is equipped with two water distribution plates, which are respectively located at the gap between the left and right ends of the bar magnetic rod and the inner wall of the equipment body.

[0010] Furthermore, the highest point of the water distribution plate is equal to 100 mm above the highest water level line.

[0011] Furthermore, there are two plum blossom wheels, which are spaced apart in the upper and lower directions on the same vertical line. The maximum horizontal height of the upper plum blossom wheel is higher than the maximum horizontal height of the water outlet. The two plum blossom wheels are also implemented in the form of a tensioned transmission chain.

[0012] Furthermore, the plum blossom wheel is driven by a reduction motor located outside the equipment body, and the part where the transmission shaft of the reduction motor is connected to the wall of the equipment body is driven through a bearing seat including a bearing.

[0013] Furthermore, each set of mud suction mechanism is equipped with a reduction motor.

[0014] Furthermore, the level of the water outlet is higher than the level of the water inlet.

[0015] The utility model discloses a rotary magnetic separation device for sewage treatment. Compared with the same type of supermagnetic devices currently on the market, the supermagnet is changed from a circular magnetic disk to a bar magnetic rod, and the rotating operation of the circular magnetic disk is changed to a rotary operation. Through this change, the contact area between the supermagnet and the sewage is increased, the amount of supermagnetic material is saved, and the price of the equipment is reduced. At the same time, for later operation and maintenance, when a bar magnetic rod has a problem, only one bar magnetic rod needs to be replaced, while the circular magnetic disk needs to be replaced as the whole disk. Therefore, in the later operation and maintenance, the maintenance cost can also be reduced. In order to improve the sludge suction effect and improve the operation stability of the equipment, two sets of sludge suction mechanisms are set, and the sludge collection mechanism is improved, thereby reducing the workload of later operation and maintenance.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-2 As shown together, the present embodiment is about the rotary magnetic separation equipment for sewage treatment, including an equipment body 2 formed with an inner cavity. In the present embodiment, the equipment body 2 is arranged as a rectangular parallelepiped, and the two corresponding sides of the equipment body 2 are respectively provided with a water inlet 1 and a water outlet 3, and the cavity of the equipment body 2 is equipped with a mud suction mechanism; the mud suction mechanism includes a plum blossom wheel 11, and a transmission chain 12 meshing with the plum blossom wheel 11, and the outer ring of the transmission chain 12 is arranged with a plurality of U-shaped magnetic grooves 13 installed with bar magnetic bars 7; the mud suction mechanism is equipped with a sludge collecting mechanism on one side of the water outlet direction, and the sludge collecting mechanism includes a mud collecting trough 9, and the mud collecting trough 9 is in frictional contact with the outer surface of the bar magnetic bar 7 through the mud scraper 8, and the mud collecting trough 9 is connected to the mud outlet 4 through a pipe connected to the inner and outer sides of the equipment body 2, and in order to allow the mud collecting trough 9 to better collect sludge and not be affected by the sewage flow, the opening of the mud collecting trough 9 is set at a position slightly higher than the highest height of the water outlet 3.

[0021] It should be noted that the mud collecting trough 9, the pipe connected thereto and the mud discharge port 4 are provided with a ramp. It can be understood that the mud collecting trough 9 is the highest point of the ramp, and the sludge collected in the mud collecting trough 9 can be discharged in time under the action of gravity.

[0022] Preferably, there are two sets of mud suction mechanisms, and the two sets of mud suction mechanisms are arranged in the inner cavity of the equipment body 2 at intervals, such as Figure 1 As shown, the interval between the two sets of mud suction mechanisms is set on the extension line from the incoming water direction to the outgoing water direction, and each set of mud suction mechanisms includes a side in the incoming water direction and a side in the outgoing water direction.

[0023] Each set of sludge suction mechanism is equipped with a sludge collection mechanism on one side of the water outlet direction, so the sludge of each set of sludge suction mechanism can be discharged in time. It should be noted here that in this embodiment, the sewage entering the equipment body 2 has been added with flocculants, coagulants and magnetic seeds in the previous treatment and has been fully stirred and mixed. It can be understood that the sewage entering the equipment body 2 has formed floc-like magnetic flocs.

[0024] A water distribution plate 6 is provided on the water inlet side of the sludge suction mechanism. Each set of sludge suction mechanism is equipped with two water distribution plates 6. The two water distribution plates 6 are respectively located at the gap positions between the left and right ends of the strip magnetic rod 7 and the inner wall of the equipment body 2. The water distribution plate 6 is used to prevent the clump of magnetic floccules from escaping the attraction of the strip magnetic rod 7, ensuring that the clump of magnetic floccules can be completely adsorbed by the strip magnetic rod 7. At the same time, in order to ensure that the water distribution plate 6 and the strip magnetic rod 7 can fit tightly, the edge of the water distribution plate 6 is preferably made of flexible rubber material.

[0025] Furthermore, in order to ensure the function of the water distribution plate 6, the highest point of the water distribution plate 6 is set to be equal to 100 mm above the highest water level line.

[0026] There are two plum blossom wheels 11, which are arranged at intervals in the same vertical line. The maximum horizontal height of the upper plum blossom wheel 11 is higher than the maximum horizontal height of the water outlet 3. The two plum blossom wheels 11 are also implemented in a tensioning transmission chain 12.

[0027] The plum blossom wheel 11 is driven by the reduction motor 5 located on the outside of the equipment body 2. The part where the transmission shaft of the reduction motor 5 is connected to the wall of the equipment body 2 is transmitted through the bearing seat 10 containing the bearing. Based on the above structure, when the reduction motor 5 is working, its transmission shaft rotates on the bearing seat 10, further driving the plum blossom wheel 11 connected to the transmission shaft to rotate, and then the plum blossom wheel 11 drives the transmission chain 12 meshing with it to rotate.

[0028] Furthermore, each set of mud suction mechanism is equipped with a reduction motor 5.

[0029] In addition, if Figure 1 As shown, the level of the water outlet 3 is higher than the level of the water inlet 1 .

[0030] Based on the above structure, when the sludge suction mechanism is operating, the clump-like magnetic flocs in the sewage are continuously adsorbed by the rotating bar magnetic bars 7. When the bar magnetic bars 7 run to the scraper plate 8 for friction contact, the clump-like magnetic flocs are scraped by the scraper plate 8 into the sludge collecting tank 9 and then discharged through the sludge discharge port 4, thereby removing the suspended matter in the sewage.

[0031] Thus, the rotary magnetic separation equipment for sewage treatment disclosed by the utility model, compared with the similar supermagnetic equipment on the market, changes the supermagnet from a circular disk to a bar magnet, and changes the rotating operation of the circular disk to a rotary operation. Through this change, the contact area between the supermagnet and the sewage is increased, the amount of supermagnetic material is saved, and the price of the equipment is reduced. At the same time, for the later operation and maintenance, when there is a problem with a bar magnet, only one bar magnet needs to be replaced, while the circular disk needs to replace the entire disk. Therefore, in the later operation and maintenance, the maintenance cost can also be reduced. In order to improve the sludge suction effect and improve the operating stability of the equipment, two sets of sludge suction mechanisms are set up, and the sludge collection mechanism is improved, thereby reducing the workload of later operation and maintenance.

[0032] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
