Description

Technical Field

[0001] The utility model relates to the technical field of equipment related to magnetic stripe processing, in particular to a wastewater treatment device used for magnetic stripe cutting processing. Background Art

[0002] Magnet processing involves transforming raw materials through various mechanical processes into magnets with specific shapes, sizes, and properties. This process typically includes material preparation, forming, finishing, magnetization, surface treatment, inspection and testing, as well as packaging and shipping. Processing methods may include slicing, grinding, milling, drilling, and chamfering, depending on the magnet type, size, and application requirements. During processing, special attention must be paid to factors such as material brittleness, heat release, and corrosion during processing to avoid damage to magnetic properties.

[0003] Magnets produce wastewater during cutting, and this wastewater needs to be treated before discharge. After searching, the Chinese patent application number is: CN201921305789.6, which discloses a complete set of cutting waste liquid treatment equipment, including a dosing device, a base, a three-phase mixed flotation device, an activated carbon adsorption device, a sterilization device and a membrane filtration device. The dosing device, the three-phase mixed flotation device, the activated carbon adsorption device, the sterilization device, the air compressor and the membrane filtration device are all fixed on the base by bolts. The dosing device and the three-phase mixed flotation device are connected by a pipeline. The three-phase mixed flotation device includes a three-phase mixer, a booster pump, a flotation tank, a scraper and a slag collecting tank. The booster pump, the three-phase mixer and the flotation tank are connected in sequence through pipelines. The three-phase mixed flotation device, the circulation pump, the activated carbon adsorption device, the sterilization device and the membrane filtration device are connected in sequence through pipelines. The dosing device includes a dosing tank and a dosing pump. The cutting waste liquid treatment complete set of equipment has a reasonable design and a compact structure and can realize automatic control of the entire device.

[0004] The above technical solution still has a defect, that is, it lacks the function of recovering magnetic powder in waste liquid. Magnetic powder is made of metals such as iron, nickel, and cobalt. These metals have high recovery value. By recycling magnetic powder, the exploitation of natural resources can be reduced, environmental pollution can be reduced, and raw materials can be provided for the manufacturing industry. Direct chemical precipitation of wastewater will cause the magnetic powder to mix with the sediment, which will be difficult to separate later and is not conducive to the recycling of magnetic powder. Therefore, we need to propose a wastewater treatment device for magnetic strip cutting processing. Utility Model Content

[0023] 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.

[0024] See also Figure 1-2 , the utility model provides a technical solution:

[0025] A wastewater treatment device for magnetic strip cutting processing, comprising:

[0026] The processing chamber 1 is provided with a sedimentation chamber 4 integrally formed at the bottom of the processing chamber 1, a sewage outlet 5 is provided at the lower end of the sedimentation chamber 4, an addition port 2 for adding chemical reagents is provided at the top of the processing chamber 1, and an overflow port 3 for the supernatant to flow out is provided on one side wall of the processing chamber 1; a support ring is provided in an annular shape on the outer wall of the processing chamber 1, and pillars are respectively arranged around the bottom of the support ring, and three groups of pillars are equidistantly arranged.

[0027] The liquid inlet bin 6 is connected to the processing bin 1 through a connecting pipe 8. A sleeve 9 is installed inside the liquid inlet bin 6, and a magnetic separator 10 is installed inside the sleeve 9.

[0028] By setting an addition port 2 at the top of the processing bin 1, an overflow port 3 on the outer wall of the processing bin 1, a sedimentation bin 4 with a sewage outlet 5 at the lower end of the processing bin 1, and a liquid inlet bin 6 above the processing bin 1, the liquid inlet bin 6 is connected to the processing bin 1 through a connecting pipe 8, and a sleeve 9 with a magnetic separator 10 is installed in the liquid inlet bin 6. In actual use, waste liquid is injected through the liquid inlet bin 6. After the waste liquid enters the sleeve 9, under the action of the magnetic separator 10, the magnetic powder and ferromagnetic impurities in the waste liquid will be adsorbed on the filter medium by the strong magnetic field, thereby achieving the filtering effect. At the same time, the filter-type magnetic separator 10 can also filter and intercept large particles of non-magnetic impurities;

[0029] After the preliminary treatment, the wastewater passes through the guide cover 7 and the connecting pipe 8 and enters the treatment chamber 1. Chemical reagents such as flocculants are added to the treatment chamber 1 through the addition port 2. After a period of time, impurities and large particles of pollutants in the wastewater form sediments and fall into the sedimentation chamber 4. The treated water can be discharged through the overflow port 3, and the sediment can be discharged through the sewage outlet 5.

[0030] In general, the device has a simple structure and is easy to use. By setting a liquid inlet tank 6 on the top of the processing tank 1 to pre-treat the wastewater, the magnetic powder in the magnet cutting wastewater can be adsorbed and recovered, reducing the procurement cost of raw materials in magnet processing and realizing the recycling of resources.

[0031] Also, see Figure 2 :

[0032] The sleeve 9 is threadedly mounted on the processing chamber 1. The magnetic separator 10 is a filter-type magnetic separator 10. The upper end of the sleeve 9 is provided with a rim 11. The upper outer wall of the sleeve 9 is provided with an external thread section 12. The upper inner wall of the liquid inlet chamber 6 is provided with an internal thread section 13. The internal thread section 13 is adapted to the external thread section 12.

[0033] By providing an external thread on the outer wall of the upper end of the sleeve 9 and correspondingly providing an internal thread inside the upper end of the liquid inlet bin 6, when installing the sleeve 9 with the magnetic separator 10, the sleeve 9 is threadedly installed in the liquid inlet bin 6. At this time, the surrounding edge 11 contacts the end face of the upper opening of the liquid inlet bin 6. This design facilitates the combined use and disassembly and cleaning of the sleeve 9 and the liquid inlet bin 6, facilitates the subsequent collection of the magnetic powder adsorbed by the magnetic separator 10, and also facilitates the maintenance of the magnetic separator 10.

[0034] After the equipment is used, the sleeve 9 is removed and can be turned upside down to allow non-magnetic impurities to fall, thereby separating the magnetic powder and non-magnetic impurities. The adsorbed magnetic powder can then be collected uniformly by scraping with a scraper.

[0035] For further information, see Figure 1 and Figure 3 :

[0036] The lower end of the sedimentation bin 4 is provided with a drain pipe 14 connected to the sedimentation bin 4. A motor 15 is mounted on the outer wall of the lower end of the drain pipe 14. The output end of the motor 15 extends into the drain pipe 14 and is fixedly connected to a shaft 16. The outer wall of the shaft 16 is provided with spiral blades 17. The drain port 5 is located on the outer wall of the lower end of the drain pipe 14.

[0037] By arranging a sewage pipe 14 at the lower end of the sedimentation bin 4, a shaft 16 with a spiral blade 17 is rotatably installed in the sewage pipe 14, and the shaft 16 is driven by a motor 15 at the bottom end of the sewage pipe 14, and the sewage outlet 5 is located on the outer wall of the lower end of the sewage pipe 14. When sewage is discharged, the sludge settles into the sewage pipe 14, and the motor 15 drives the spiral blade 17 to rotate to discharge the sludge quickly, thereby improving the sewage discharge efficiency of the device. At the same time, it can avoid the problem of sludge clogging when sewage is discharged by gravity.

[0038] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
