[0022] The embodiments of the present application provide an alkali solution purification system, which solves the problems in the existing alkali solution purification system that the purification equipment has a complex structure, is difficult to maintain, and has a high cost. Among them, the impurities contained in the alkali solution are not easy to be discharged. This is mainly because the impurities contain a large amount of ferromagnetic impurities. On the one hand, the ferromagnetic impurities are easy to accumulate in the filter screen of the purification system, causing blockage and increasing the difficulty of maintenance and repair. On the other hand, since the ferromagnetic impurities mixed in the alkali solution are difficult to be completely filtered, the quality of the alkali solution is reduced, resulting in an increase in the waste and discharge of the alkali solution, an increase in environmental pollution, and a reduction in product quality and stability.
[0023] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.
[0024] The embodiments of the present utility model disclose an alkali solution purification system. According to the attached Figures 1-3 As shown, it includes an alkali solution circulation tank 1. A first pump group 2 is connected to the alkali solution circulation tank 1 through a pipeline. The first pump group 2 is connected to a permanent magnet filter 3 through a pipeline. The permanent magnet filter 3 and the alkali solution circulation tank 1 are connected through a pipeline;
[0025] The permanent magnet filter 3 includes a barrel body 31 and multiple groups of magnetic rods 32 arranged inside the barrel body 31. A flushing unit and a slag discharging unit are connected to the permanent magnet filter 3;
[0026] The flushing unit includes a flushing water tank 6 and a second water pump 7. The flushing water tank 6 and the second water pump 7 are connected by a pipeline. The second water pump 7 is connected to the permanent magnet filter 3 through a pipeline. The slag discharging unit is used to discharge the slag from the flushing wastewater inside the permanent magnet filter 3 by the flushing unit.
[0027] The lye purification system mainly consists of a permanent magnet filter 3, a flushing unit and a slag discharging unit. During use, through the dual functions of the permanent magnet filter 3 and the slag discharging unit, impurities in the lye can be efficiently removed. Through optimized design and an efficient purification process, the system can reduce the waste and discharge of lye, reduce environmental pollution. The system has a compact structure, and its components are easy to disassemble and replace, facilitating daily maintenance and upkeep. The purified lye can better meet the production requirements, improving the quality and stability of products.
[0028] The slag discharging unit includes a buffer tank 4 and a permanent magnet drum 5. The buffer tank 4 and the permanent magnet filter 3 are connected by a pipeline. The buffer tank 4 and the permanent magnet drum 5 are connected by a pipeline. The permanent magnet drum 5 is connected to the lye circulation tank 1 through a pipeline. The buffer tank 4 receives the preliminarily purified lye flowing out from the permanent magnet filter 3, playing a role in buffering and stabilizing the flow rate. Through the dual functions of the permanent magnet filter 3 and the permanent magnet drum 5, impurities in the lye can be efficiently removed.
[0029] The permanent magnet drum 5 includes a liquid inlet tank 51 and a drum 52 rotatably connected inside the liquid inlet tank 51. Permanent magnet magnets 53 are provided inside the drum 52. The liquid inlet tank 51 receives the lye from the buffer tank 4 and guides it to the position of the drum 52 for further purification. Permanent magnet magnets 53 are installed inside the drum 52. By rotating and contacting the lye, the remaining magnetic impurities are adsorbed. The permanent magnet magnets 53 provide a strong magnetic field to adsorb ferromagnetic impurities in the lye;
[0030] A pressure roller 54 is also rotatably connected inside the liquid inlet tank 51. The pressure roller 54 is in contact with the drum 52. The permanent magnet drum 5 further includes a scraper plate 55 fixedly connected to the liquid inlet tank 51. The pressure roller 54 is used to press the magnetic impurities tightly on the drum 52 to form a mud cake. The scraper plate 55 is used to scrape off the mud cake and discharge it from the system to achieve slag discharge.
[0031] A collection trough 501 is provided at the bottom of the permanent magnet drum 5. The collection trough 501 is located below the permanent magnet drum 5 to facilitate the collection of impurities falling off the drum.
[0032] A compressed air inlet 301 and a compressed air exhaust port 302 are provided on the side of the permanent magnet filter 3. The compressed air inlet 301 provides compressed air into the filter. The compressed air is used to assist in purging impurities on the sleeve 33 and the magnetic rod 32, improving the purification effect. The compressed air exhaust port 302 is used to discharge the compressed air no longer needed inside the filter.
[0033] The barrel body 31 is provided with multiple sets of sleeves 33. The sleeves 33 are sleeved outside the magnetic rods 32. The barrel body 31 is also provided with a cylinder 34. The cylinder 34 is used to control the opening and closing of the pipeline of the permanent magnet filter 3, providing safety protection for the permanent magnet filter 3. The main function of the sleeve 33 is to protect the magnetic rod 32 from direct impact and wear, and ensure that the lye can flow evenly through the surface of the magnetic rod 32. The sleeve 33 is made of non-magnetic material to avoid interfering with the magnetic field; the cylinder 34 is used to quickly close the valve or passage connected to the permanent magnet filter 3 to prevent the leakage of lye or other safety accidents.
[0034] The flushing water tank 6 is provided with a water replenishing pipe 601. A pressure transmitter 8 is provided on the pipeline between the second water pump 7 and the permanent magnet filter 3. The water replenishing pipe 601 replenishes water source for the flushing water tank 6. The pressure transmitter 8 is used to monitor and adjust the pressure of the flushing water to ensure the flushing effect.
[0035] The working process of the lye purification system is divided into the process of the lye to be purified entering the permanent magnet filter 3, the purification process of the permanent magnet filter, the flushing process, and the process of treating and recycling the flushing wastewater;
[0036] Step 1, the lye to be purified enters the permanent magnet filter 3
[0037] The lye to be purified is pumped out from the lye circulation tank 1 by the first pump group 2 and sent into the permanent magnet filter 3.
[0038] Step 2, the purification process of the permanent magnet filter 3:
[0039] Inside the permanent magnet filter 3, the lye flows through multiple sets of sleeves 33, and the magnetic rods 32 inside the sleeves 33 use magnetic force to adsorb magnetic impurities in the lye.
[0040] Compressed air enters the permanent magnet filter 3 through the compressed air inlet 301. The compressed air is used to assist in purging impurities on the sleeves 33 and the magnetic rods 32, improving the purification effect. The compressed air exhaust port 302 discharges the used compressed air.
[0041] Step 3, the flushing process:
[0042] When the impurities accumulated on the magnetic rods 32 in the permanent magnet filter 3 reach a certain level, flushing is required. At this time, the flushing water in the flushing water tank 6 is sent into the permanent magnet filter 3 after being pressurized by the second water pump 7 and the pressure transmitter 8.
[0043] The flushing water flushes the sleeves 33 and the magnetic rods 32, washing down the adsorbed impurities to form flushing wastewater.
[0044] Step 4, treatment and recycling of the flushing wastewater:
[0045] After the flushing wastewater flows out from the permanent magnet filter 3, it enters the buffer tank 4 for temporary storage.
[0046] The wastewater in the buffer tank 4 is then sent to the permanent magnetic drum 5 for treatment. In the permanent magnetic drum 5, the drum 52 rotates. Inside the drum 52, there are permanent magnetic magnets 53. The drum 52 contacts the wastewater through rotation. Through the magnetic force of the permanent magnetic magnets 53, the drum 52 adsorbs the remaining magnetic impurities. The pressure roller 54 presses the magnetic impurities tightly on the drum 52 to form a mud cake. Subsequently, the scraper plate 55 shovels off the mud cake and discharges it from the system to achieve slag discharge. The discharged slag is collected by the collection tank 501.
[0047] The lye treated by the permanent magnetic drum 5 is recovered and sent back to the lye circulation tank 1 for recycling.
