[0002] ‌Magnetic separation drum is an important equipment in magnetic separation technology. It is mainly used to disperse and recover magnetic flocs. It is widely used in water purification and sewage treatment. When used, it can effectively separate magnetic solid particles in sewage and collect the magnetic solid particles. At the same time, it can remove some non-magnetic impurities to achieve water purification.

[0003] The magnetic separation drum is usually composed of a floc dispersion device, a magnetic seed recovery device and a magnetic seed storage box. When in use, the drum rotates continuously to magnetize the magnetic solid particles in the grinding fluid flowing nearby and adsorb them to the outer surface of the drum. However, after the sewage inside the magnetic separation drum is separated and purified, the wastewater will be directly discharged. In order to make the sewage that needs to be purified react better with the added reagents, clean water needs to be introduced into the interior for blending, resulting in low wastewater utilization efficiency and increased sewage treatment capacity.

[0012] Compared with the prior art, the magnetic separation drum for wastewater treatment described in the present invention has the following beneficial effects:

[0013] 1. In order to improve the utilization rate of wastewater inside the magnetic separation drum, after the sewage is initially separated, a part of it will be stored in the wastewater temporary storage chamber in the form of wastewater. When the sewage in the dispersion chamber needs to reduce the internal impurity concentration to facilitate the addition of reagents for better effect, the suction pump on one side of the box is started. The suction pump guides the wastewater in the wastewater temporary storage chamber through the connecting pipe and the drain pipe through the first connecting branch pipe, the second connecting branch pipe and the water pipe to the sewage inlet pipe. The sewage is then guided into the dispersion chamber by the sewage inlet pipe to be mixed with the sewage.

[0014] 2. In order to avoid a large amount of sewage still existing in the sludge after separation, the sludge will fall into the filter frame after passing through the sludge discharge valve. At this time, the wastewater in the sludge will pass through the filter frame and be filtered into the sludge treatment chamber. At the same time, the torque motor on one side of the box will drive the sludge discharge auger to rotate through the coupling at the output end, and discharge the filtered sludge from the sludge discharge port. The sludge discharge auger will drive the sludge to turn continuously while discharging the sludge, thereby improving the solid-liquid separation efficiency, effectively reducing the water content of the sludge, and pumping it to the dispersion chamber for further treatment. The magnetic separation drum that can be used for the wastewater can effectively reduce the water content of the sludge, facilitate the subsequent treatment of the sludge, and facilitate the centralized collection and treatment of wastewater.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The magnetic separation drum that can be used for wastewater described herein includes a box body 1, a dispersion chamber 101 and a wastewater temporary storage chamber 102. The dispersion chamber 101, the wastewater temporary storage chamber 102 and the sludge treatment chamber 103 are provided inside the box body 1. Drive motors 104 are installed inside the dispersion chamber 101 and the wastewater temporary storage chamber 102. The output ends at the bottom of the two drive motors 104 are connected to the stirring rod 105 through a coupling. A magnetic separation drum 2, a scraper 201 and a partition 202 are installed inside the box body 1. A mud discharge valve 203 is installed at the bottom of the partition 202. A sewage inlet pipe 3 is connected to one side of the box body 1, and a drain pipe 301 is installed on the other side of the box body 1.

[0022] The outside of the drain pipe 301 is connected to one side of the suction pump 401 through the connecting pipe 4, and the other side of the suction pump 401 is connected to one end of the first connecting branch pipe 402. The other end of the first connecting branch pipe 402 is connected to the bottom of the water pipe 404. The side of the water pipe 404 away from the first connecting branch pipe 402 is connected to the drain pipe 301 through the second connecting branch pipe 403. One side of the suction pump 401 is connected to the box 1. The inside of the water pipe 404 is connected to the bearing seat. A water auger 406 is rotatably installed, and a servo motor 405 is installed at the end of the water pipe 404 away from the bearing seat. The output end of the servo motor 405 is connected to the water auger 406 through a coupling. Scraper rods 407 are welded at equal intervals on the outside of the water auger 406. The outer side of the scraper rod 407 fits against the inner wall of the water pipe 404, and one side of the scraper 201 fits against the magnetic separation drum 2. Control valves are installed at the drain pipe 301, the second connecting branch pipe 403 and the sewage inlet pipe 3.

[0023] In the specific implementation, in order to improve the utilization rate of the wastewater inside the magnetic separation drum, after the sewage is initially separated, a part of it will be stored in the form of wastewater inside the wastewater temporary storage chamber 102. When the sewage in the dispersion chamber 101 needs to reduce the internal impurity concentration, it is convenient for adding reagents to work better. The suction pump 401 on one side of the box body 1 is started. The suction pump 401 guides the wastewater in the wastewater temporary storage chamber 102 through the connecting pipe 4 and the drain pipe 301 through the first connecting branch pipe 402, the second connecting branch pipe 403 and the water pipe 404 into the sewage inlet pipe 3, and then the sewage inlet pipe 3 guides the wastewater to the sewage outlet. The wastewater enters the dispersion chamber 101 and mixes with the sewage, thereby reducing the concentration of impurities in the sewage; at the same time, a water delivery auger 406 driven by a servo motor 405 is provided in the water pipe 404, which can effectively prevent the wastewater from flowing back, and the scraper rods 407 are equidistantly connected to the outside of the water delivery auger 406, which can clean the inner wall of the water pipe 404 to prevent small impurities from adhering to the pipe. The magnetic separation drum that can be used for the wastewater can guide the wastewater in the wastewater temporary storage chamber 102 into the dispersion chamber 101 for reuse, effectively improving the utilization rate of the wastewater and reducing the amount of sewage treatment.

[0024] See Figure 2 、 Figure 3 and Figure 4 It can be seen that one side of the sludge treatment chamber 103 is connected to the connecting pipe 4 through the wastewater diversion pipe 5, a filter frame 6 is welded inside the sludge treatment chamber 103, and the filter frame 6 is arranged obliquely, a mud discharge port 601 is opened on one side of the box body 1, and a torque motor 603 is installed on the other side of the box body 1, one side of the filter frame 6 is connected to the mud discharge port 601, and a mud discharge auger 602 is arranged inside the filter frame 6, and the output end of the torque motor 603 is connected to one end of the mud discharge auger 602 through a coupling.

[0025] During specific implementation, in order to avoid a large amount of sewage still remaining in the sludge after separation, the sludge will fall into the filter frame 6 after passing through the sludge discharge valve 203. At this time, the wastewater in the sludge will pass through the filter frame 6 and be filtered into the sludge treatment chamber 103. At the same time, the torque motor 603 on one side of the box body 1 will drive the sludge discharge auger 602 to rotate through the coupling at the output end, and discharge the filtered sludge from the sludge discharge port 601. The sludge discharge auger 602 will drive the sludge to turn continuously while discharging the sludge, thereby improving the solid-liquid separation efficiency and effectively reducing the water content of the sludge. When the suction pump 401 on one side of the box body 1 is started, the wastewater in the sludge treatment chamber 103 will be pumped out through the wastewater diversion pipe 5 and pumped to the dispersion chamber 101 for further treatment. The magnetic separation drum that can be used for the wastewater can effectively reduce the water content of the sludge, which is convenient for subsequent treatment of the sludge and is conducive to the centralized collection and treatment of wastewater.

[0026] In summary, when using the magnetic separation drum that can be used for wastewater, the sewage is introduced into the dispersion chamber 101 through the sewage inlet pipe 3 on one side of the box body 1, and is stirred by the driving motor 104 and the stirring rod 105, and then evenly mixed with the corresponding reagent to form flocs. During the stirring process, the flocs will flow to the magnetic separation drum 2. Under the action of the continuous rotation of the magnetic separation drum 2, the magnetic solid particles in the grinding fluid flowing to the vicinity are magnetized, and after being adsorbed to the outer surface of the magnetic drum, they are scraped off by the scraper 201 and fall through the partition 202 and the mud discharge valve 203 at the bottom of the partition 202 to the filter frame 6 and then discharged. The wastewater that has completed magnetic separation will enter the wastewater temporary storage chamber 102 and be discharged through the drain pipe 301.
