Description

Technical Field

[0001] This utility model relates to the field of spray filtration technology, specifically a spray filtration and cooling device for a magnet sintering furnace. Background Technology

[0002] In the production and processing of magnets, sintering is an essential step. During the sintering process, a large amount of waste gas is generated. The waste gas must be filtered before it can be discharged into the air. A common filtration method is spray filtration, which involves passing the waste gas into the inner cavity of a spray tower so that water vapor can come into full contact with the waste gas. After filtration through bio-balls, activated carbon, etc., the waste gas can be guaranteed to meet emission standards.

[0003] A magnetic sintering furnace spray filtration and cooling environmental protection device disclosed in Chinese utility model patent application CN216432533U, utilizes a second spray head and an aluminum alloy cooler in conjunction during the filtration process. This interaction effectively cools the exhaust gas, preventing excessively high temperatures from affecting the filtration efficiency of the bio-sphere layer and significantly improving the filtration effect. Furthermore, the combined effect of the second spray head and the aluminum alloy cooler allows for the removal of fine particles carried in the rising water vapor. The activated carbon layer, when sprayed, adheres to the outside of the aluminum alloy cooler. This spray washes away the fine particles on the outside of the cooler, which are then adsorbed onto the surface of the biosphere layer, further improving the filtration effect. However, existing devices only cool the flue gas by spraying water. During the water cooling process, the particulate matter in the flue gas cannot be reduced, which can clog the nozzles and cause them to malfunction. Furthermore, it is difficult to quickly replace the activated carbon when needed, and it is also difficult for staff to quickly monitor the water level in the tank when filling it. Therefore, this utility model is proposed to solve these problems. Utility Model Content

[0025] 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.

[0026] Example: Reference Figures 1-6 The magnetic sintering furnace spray filtration and cooling device shown includes a support frame 1, a support base 2 inserted into the inner side wall of the support frame 1, a discharge valve 3 inserted into the lower surface of the support base 2, a water tank assembly 4 provided on the surface of the support frame 1, a support cylinder 5 provided on the upper surface of the support base 2, a dust filter 6 inserted into the inside of the support cylinder 5, a spray assembly 7 inserted into the inside of the dust filter 6, a support filter box 9 fixed to the lower part of the surface of the support cylinder 5 by support bolts 8, a storage filter box 11 fixed to the upper part of the surface of the support cylinder 5 by storage bolts 10, and a support cover 12 threaded through one end of the support cylinder 5.

[0027] As a preferred embodiment of this example, Figures 2 to 6As shown, a support base 2 is inserted into the inner wall of the support frame 1. A discharge valve 3 is inserted into the lower surface of the support base 2. A discharge port is opened on the lower surface of the support base 2, and a discharge valve 3 is inserted into the discharge port. A water tank assembly 4 is provided on the surface of the support frame 1. The water tank assembly 4 includes a water tank 401, a liquid level sensor 402, a water inlet valve 403, a water pump 404, and a water pipe 405. A liquid level sensor 402 is inserted into the upper surface of the water tank 401. The liquid level sensor 402 is a pressure sensor for measuring liquid level. The static pressure submersible liquid level transmitter is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffused silicon sensitive element or a ceramic capacitive pressure sensitive sensor to convert the static pressure into an electrical signal, which is then processed by temperature compensation and linear... The signal is corrected and converted into a standard electrical signal. A water inlet valve 403 and a water pump 404 are sequentially inserted from front to back on the upper surface of the water tank 401. A water pipe 405 is inserted into one end of the water pump 404. A support cylinder 5 is provided on the upper surface of the support base 2. A smoke inlet pipe 501 is inserted into the surface of the support cylinder 5. A smoke outlet is opened on the upper surface of the support cover 12. A dust filter 6 is inserted inside the support cylinder 5. A spray assembly 7 is inserted inside the dust filter 6. The spray assembly 7 includes a smoke hood 701, a drain hole 702, a nozzle 703, a seepage seat 704, and a seepage hole 705. A drain hole 702 is opened on the lower part of the surface of the smoke hood 701. A nozzle 703 is inserted inside the smoke hood 701. A seepage seat 704 is sleeved on one end of the nozzle 703. The upper surface of the bearing cylinder 5 has a seepage hole 705. The lower part of the surface of the bearing cylinder 5 is fixed with a bearing filter box 9 by a bearing bolt 8. The surface of the bearing filter box 9 has a bearing threaded hole, and the bearing bolt 8 passes through the internal thread of the bearing threaded hole. The lower surface of the spray assembly 7 has a water pipe hole. The lower surface of the spray head 703 is connected to a water pipe 405. The upper part of the surface of the bearing cylinder 5 is fixed with a storage filter box 11 by a storage bolt 10. The bearing filter box 9 has a bearing filter screen 901 inserted inside. The storage filter box 11 has a storage filter screen 111 inserted inside. The surface of the bearing cylinder 5 near the storage filter box 11 has a storage groove. The storage filter box 11 is slidably connected inside the storage groove. The surface of the bearing cylinder 5 near the bearing filter box 9 has a... The device has a support groove, inside which a support filter box 9 is slidably connected. The support filter box 9 is fixed to the lower part of the surface of the support cylinder 5 by support bolts 8. An inlet pipe 501 is inserted into the surface of the support cylinder 5. An outlet is opened on the upper surface of the support cover 12. An outlet filter box 11 is fixed to the upper part of the surface of the support cylinder 5 by storage bolts 10. One end of the support cylinder 5 is threaded through the support cover 12. During use, by inserting the inlet pipe 501 into the outlet of the magnet sintering furnace, the flue gas from the magnet sintering furnace enters the support cylinder 5 through the inlet pipe 501. The flue gas in the support cylinder 5 moves upward and is discharged from the outlet. Clean water is drawn from the water tank 401 by the water pump 404 and sprayed intermittently from the nozzle 703 through the water pipe 405.The height of the water sprayed from nozzle 703 is lower than that of the filter box 11, allowing the water to cool and absorb heat from the flue gas in the carrier cylinder 5, rapidly reducing the flue gas temperature. Simultaneously, the water also adsorbs and purifies the flue gas, better adsorbing particulate matter and removing dust, thus reducing pollution emissions. The smoke hood 701 blocks the flue gas around nozzle 703, reducing its flow towards nozzle 703 and ensuring the flue gas accumulates at a height higher than the spray height. This ensures that the intermittently sprayed water from nozzle 703 consistently prevents the accumulated flue gas from approaching nozzle 703. 3. This reduces the amount of particulate matter in the flue gas entering the nozzle 703, minimizing clogging and allowing the nozzle 703 to spray more effectively, thus improving equipment efficiency. The flue gas flowing through the carrier cylinder 5 passes through the storage filter screen 111, which contains activated carbon. The activated carbon in the storage filter screen 111 adsorbs pollutants in the flue gas, thus better purifying the flue gas and reducing the emission of pollutants, thereby protecting the environment. The water sprayed from the nozzle 703 falls into the carrier filter box 9. Activated carbon is placed on the filter screen 901, which adsorbs and purifies the water after treating the flue gas. This adsorption of pollutants in the treated water reduces wastewater discharge and environmental pollution. The water inlet valve 403 connects to an external water inlet, allowing water to be added to the water tank 401. A level sensor 402 monitors the water level in the tank, enabling operators to easily monitor the water volume and reducing workload. During operation, the filter screen... The carrier filter box 9 is pushed into the carrier cylinder 5, and the carrier bolt 8 is tightened to fix the carrier filter box 9 onto the carrier cylinder 5. Similarly, the storage filter box 11 is pushed into the carrier cylinder 5, and the storage bolt 10 is tightened to fix the storage filter box 11 onto the carrier cylinder 5. This allows for quick fixing and disassembly of the carrier filter box 9 and the storage filter box 11, facilitating rapid replacement of the activated carbon and improving pollutant adsorption. Tightening the carrier cover 12 fixes the carrier cover onto the carrier cylinder 5, further enhancing worker efficiency.

[0028] The working principle of this practical application is as follows:

[0029] During operation, the operator first secures the support cover 12 to the support cylinder 5 by screwing it on. Then, the operator inserts the flue gas inlet pipe 501 into the flue gas outlet of the magnet sintering furnace, allowing the flue gas to enter the support cylinder 5 through the inlet pipe 501. This causes the flue gas in the support cylinder 5 to rise and exit through the flue gas outlet. Next, the water pump 404 draws clean water from the water tank 401, and the clean water is intermittently sprayed from the nozzle 703 through the water pipe 405. The height of the water sprayed from the nozzle 703 is lower than the storage filter box 11, thus allowing the clean water to cool and absorb heat from the flue gas in the support cylinder 5, rapidly reducing the flue gas temperature and simultaneously absorbing heat from the flue gas. The system is equipped with a purification system to better adsorb particulate matter in the flue gas, improve dust removal, and reduce pollution emissions. The smoke hood 701 blocks the flue gas around the nozzle 703, reducing its flow towards the nozzle and ensuring the flue gas accumulates above the spray height. This prevents the intermittently sprayed water from the nozzle from approaching it, thus reducing particulate matter entering and clogging the nozzle. This allows the nozzle to spray more effectively, improving equipment efficiency. The flue gas flows through the carrying cylinder 5 and passes through the storage filter 111. Filter screen 111 contains activated carbon, which adsorbs pollutants in the flue gas, thus better purifying the flue gas and reducing the emission of pollutants, thereby protecting the environment. Water sprayed from nozzle 703 falls into the carrier filter box 9, where activated carbon on the carrier filter 901 adsorbs and purifies the treated flue gas water, reducing wastewater discharge and further protecting the environment. Water is added to the water tank 401 through the water inlet, and the level is monitored by the liquid level sensor 402. The water level in water tank 401 is sensed by a level sensor 402, which detects the water level in water tank 401. This allows staff to better monitor the water level in water tank 401, reducing their workload. When it is time to replace the activated carbon, the carrier filter box 9 is pushed into the carrier cylinder 5, and the carrier bolt 8 is tightened to fix the carrier filter box 9 onto the carrier cylinder 5. Similarly, the storage filter box 11 is pushed into the carrier cylinder 5, and the storage bolt 10 is tightened to fix the storage filter box 11 onto the carrier cylinder 5. This allows for quick fixing and disassembly of the carrier filter box 9 and the storage filter box 11, enabling rapid replacement of the activated carbon and better adsorption of pollutants.
