Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a magnesium ion recovery and treatment system for magnesium glycinate production wastewater. Background Technology

[0002] The industrial production of magnesium glycinate generates a large amount of waste liquid, which is rich in magnesium ions. To achieve resource recycling, the industry generally adopts the method of packing adsorption to enrich and recover magnesium ions in the waste liquid.

[0003] Traditional magnesium ion waste liquid recovery and treatment equipment has many shortcomings in actual use. First, the internal packing arrangement of traditional equipment is relatively fixed and simple. During the flow of water, the water flow is affected by gravity, and a blind zone is easily formed at the top of the packing tube. This makes it difficult for the production waste liquid to reach this area and fully contact and react with the packing throughout the area. Ultimately, this leads to a reduction in the adsorption and recovery efficiency of magnesium ions in the waste liquid, thus affecting subsequent water pollution treatment.

[0004] Secondly, some traditional equipment relies on a single water flow method to complete the waste liquid diversion operation. During long-term water injection, although the water flow blind zone will gradually shrink, the lack of a structure for rapid air venting and water filling makes the internal flow blind zone disappear slowly, thus hindering the waste liquid from fully wetting the packing material. This results in low actual utilization rate of the packing material and also restricts the overall waste liquid treatment throughput, making it difficult to meet the production needs of continuous recycling and treatment of large quantities of waste liquid. Summary of the Invention

[0005] In view of the problems of existing technology, such as blind spots in water flow, low utilization rate of packing material, poor magnesium ion recovery efficiency, and low waste liquid treatment throughput, a magnesium ion recovery and treatment system for glycine magnesium production waste liquid is proposed.

[0011] Furthermore, the outer wall of the filter screen is fixedly connected to the inner wall of the water inlet pipe, and the end of the water blocking pipe away from the first filter plate is fixedly connected to the side wall of the limiting pipe.

[0012] Furthermore, the extrusion component includes a fitting ring fixedly disposed on the outer wall of the fixing pin, a spring sheet fixedly disposed on the inner side wall of the fitting ring, a push rod slidably disposed on the inner wall of the fixing ring through a movable hole, an extrusion ring fixedly disposed on one end of the push rod, and a contact ring fixedly disposed on the other end of the push rod.

[0013] Furthermore, the movable component includes a sliding ring slidably disposed on the outer wall of the limiting tube, a sliding hole opened on the inner wall of the sliding ring, a blocking block fixedly disposed on the bottom of the side wall of the sliding ring, a connecting tube fixedly disposed on the side wall of the sliding ring, an internal thread plate fixedly disposed on the inner side wall of the connecting tube away from the sliding ring, and a compression ring fixedly disposed on the side wall of the internal thread plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1.

[0019] 2. This device utilizes the short-term rotation of the partition shaft to evenly distribute the packing material, eliminating the blind zone of water flow at the top of the packing tube, allowing the waste liquid to fully contact the adsorption packing material, thereby improving the adsorption and recovery efficiency of magnesium ions in the waste liquid. The sequential installation of the first and second filter plates achieves double-layer filtration, which can effectively intercept solid impurities in the waste liquid, prevent impurities from accumulating and clogging the pipeline and adsorption packing material, and ensure the long-term smooth operation of the equipment.

[0020] 3. The equipment has a built-in linkage damping limit structure, which can offset the inertial force generated by the rotation of the separator blades by elastic compression friction, thereby reducing shaft idling and vibration, thus reducing structural wear and operating noise, and extending the overall service life of the equipment.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] Example 1, referring to Figure 1 - Figure 6This invention provides a magnesium ion recovery and treatment system for glycine magnesium production waste liquid, comprising a frame 1, a control cabinet 2 fixedly connected to the outer wall of the frame 1, a water pump 3 fixedly connected to the outer wall of the frame 1, and a separation component 4 fixedly connected to the outer wall of the frame 1, and a drainage component 5 fixedly connected to the inner wall of the separation component 4. The separation component 4 includes an inlet pipe 42 fixedly connected to the frame 1, a packing pipe 41 fixedly connected to the side wall of the inlet pipe 42, an outlet pipe 43 fixedly connected to the outer wall of the end of the packing pipe 41 away from the inlet pipe 42, a servo motor 44 fixedly connected to the outer wall of the outlet pipe 43, and a distributor fixedly connected to the output end of the servo motor 44. The components include: a partition blade 45; a filter screen 47 rotatably connected to the outer wall of the partition blade 45; and a drainage assembly 5 including a fixed component 51 fixedly connected to the inner side wall of the outlet pipe 43, a limiting component 57 slidably connected to the inner wall of the fixed component 51, a fixing pin 59 fixedly connected to the inner wall of the fixed component 51, a squeezing component 52 fixedly connected to the outer wall of the fixed component 51, a movable component 53 slidably connected to the outer wall of the fixed component 51, a connecting pipe 54 fixedly connected to the side wall of the fixed component 51, a second filter plate 56 fixedly connected to the inner wall of the outlet pipe 43, a water-blocking pipe 58 fixedly connected to the inner side wall of the second filter plate 56, and a first filter plate 55 fixedly connected to the outer wall of the water-blocking pipe 58.

[0036] Specifically, during actual operation, the control cabinet 2 outside the frame 1 controls the water pump 3 to pump the glycine magnesium production waste liquid into the separation component 4. The waste liquid is first introduced into the equipment through the inlet pipe 42, and then passes through the filter screen 47 into the packing tube 41. The packing tube 41 is filled with adsorption resin packing, which adsorbs and recovers magnesium ions in the waste liquid, thereby achieving the interception and enrichment of magnesium ions. During the operation of the equipment, the servo motor 44 drives the separator blade 45 to rotate slightly. Unlike the continuous rotation structure, the separator blade 45 only rotates at a short angle, which disperses the packing inside the packing tube 41 in a spiral manner. The packing is evenly filled in the water flow area between the first filter plate 55 and the filter screen 47, thereby improving the problem that the water flow at the top of the packing tube 41 is difficult to reach and the packing utilization rate is low under the gravity of traditional equipment, ensuring that the waste liquid and the packing are in full contact, and ensuring the basic recovery efficiency of magnesium ions.

[0037] Reference Figure 1 - Figure 6The drainage assembly 5 includes a fixed component 51 fixedly connected to the inner side wall of the outlet pipe 43, a limiting component 57 slidably connected to the inner wall of the fixed component 51, a fixing pin 59 fixedly connected to the inner wall of the fixed component 51, a squeezing component 52 fixedly connected to the outer wall of the fixed component 51, a movable component 53 slidably connected to the outer wall of the fixed component 51, a connecting pipe 54 fixedly connected to the side wall of the fixed component 51, a second filter plate 56 fixedly connected to the inner wall of the outlet pipe 43, a water-blocking pipe 58 fixedly connected to the inner side wall of the second filter plate 56, and a first filter plate 55 fixedly connected to the outer wall of the water-blocking pipe 58.

[0038] Specifically, after the waste liquid completes magnesium ion adsorption through the packing tube 41, it continues to flow and enters the drainage component 5. The water flows through the first filter plate 55 and the second filter plate 56 in sequence for double-layer filtration, effectively intercepting impurities and particles in the waste liquid. The filtered waste liquid finally flows into the water storage area formed by the outlet pipe 43, the second filter plate 56, the water blocking pipe 58 and the fixing ring 511 of the fixing component 51, thus completing the temporary storage of waste liquid.

[0039] Reference Figure 1 - Figure 7 The fixing component 51 includes a fixing ring 511 fixedly connected to the inner side wall of the water outlet pipe 43, a connecting hole 512 opened in the inner wall of the fixing ring 511, a movable hole 513 opened in the inner wall of the fixing ring 511, a limiting tube 514 fixedly connected to the side wall of the connecting hole 512, a limiting groove 515 opened in the outer wall of the limiting tube 514, a rubber tube 516 fixedly connected to the inner side wall of the limiting tube 514, and a slot 517 opened in the outer wall of the rubber tube 516. The outer wall of the filter screen 47 is fixedly connected to the inner wall of the water inlet pipe 42, and the end of the water blocking tube 58 away from the first filter plate 55 is fixedly connected to the side wall of the limiting tube 514.

[0040] Specifically, during the waste liquid treatment process, the servo motor 44 can drive the separator blade 45 to rotate in the forward direction. The threaded groove 46 on the outer wall of the separator blade 45 and the internal threaded plate 535 of the moving part 53 form a threaded transmission engagement, which drives the internal threaded plate 535 to move as a whole, thereby driving the sliding ring 531 to slide along the outer wall of the limiting tube 514. During the sliding process, the sliding ring 531 slides on the connecting tube 54 through the sliding hole 532.

[0041] Reference Figure 1 - Figure 7 , Figure 9 and Figure 11The movable component 53 includes a sliding ring 531 slidably connected to the outer wall of the limiting tube 514, a sliding hole 532 opened in the inner wall of the sliding ring 531, a blocking block 533 fixedly connected to the bottom of the side wall of the sliding ring 531, a connecting tube 534 fixedly connected to the side wall of the sliding ring 531, an internal thread plate 535 fixedly connected to the inner side wall of the connecting tube 534 away from the sliding ring 531, and a compression ring 536 fixedly connected to the side wall of the internal thread plate 535. The outer wall of the spring piece 522 contacts the outer wall of the contact ring 523. The inner wall of the internal thread plate 535 is threadedly connected to the outer wall of the separator blade 45 through the threaded groove 46. The outer wall of the bottom of the blocking block 533 is slidably connected to the inner side wall of the water outlet pipe 43.

[0042] Specifically, the sliding ring 531 drives the connecting pipe 534 and the pressure ring 536 to move synchronously on the one hand, and drives the blocking block 533 on the side wall to slide along the inner wall of the outlet pipe 43 on the other hand, gradually blocking and reducing the flow area of ​​the outlet of the outlet pipe 43 until the outlet is completely blocked. With the servo motor 44 switching between forward and reverse rotation, the equipment can achieve alternating operation of negative pressure water intake and high pressure drainage, continuously disturbing the water flow and air flow inside the packing tube 41, quickly expelling the air left in the gap of the packing, thereby accelerating the elimination of the airflow stagnation blind zone, so that the waste liquid can fully wet the entire packing area, thereby improving the effective utilization rate of the packing and stabilizing the magnesium ion recovery efficiency.

[0043] Example 2, refer to Figure 1 - Figure 8 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the extrusion component 52 includes a fitting ring 521 fixedly connected to the outer wall of the fixing pin 59, a spring piece 522 fixedly connected to the inner side wall of the fitting ring 521, a push rod 524 slidably connected to the inner wall of the fixing ring 511 through the movable hole 513, an extrusion ring 525 fixedly connected to one end of the push rod 524, and a contact ring 523 fixedly connected to the other end of the push rod 524.

[0044] Specifically, during the reciprocating sliding operation of the sliding ring 531, when the sliding ring 531 moves, it drives the pressure ring 536 to approach the slider 571 of the limiting component 57. When the pressure ring 536 contacts the second pressing surface 574 of the slider 571, it can press the slider 571, causing it to slide away from the axis of the limiting tube 514 along the limiting groove 515. During the sliding process of the slider 571, the damping rod 575 and the tension spring 576 are stretched. At the same time, the pressing ring 525 is pressed through the top first pressing surface 572, pushing the push rod 524 to slide outward along the movable hole 513 of the fixed ring 511, causing the contact ring 523 to move synchronously and press the spring piece 522. Since the fitting ring 521 is fixed on the fixed plate by the fixing pin 59 and the connecting hole 512, the spring piece 522 of the pressing component 52 shrinks and fits against the outer wall of the fitting ring 521 at this time.

[0045] Reference Figure 1 - Figure 10 The limiting component 57 includes a slider 571 slidably connected to the inner wall of the limiting tube 514 via a limiting groove 515, a first extrusion surface 572 formed on the outer wall of the top of the slider 571, an extrusion protrusion 573 fixedly connected to the outer wall of the middle part of the bottom end of the slider 571, a second extrusion surface 574 formed on the outer wall of the bottom of the slider 571, a damping rod 575 fixedly connected to the outer wall of the middle part of the top of the slider 571, and a tension spring 576 sleeved on the outside of the damping rod 575. The outer wall of the damping rod 575 on the side away from the slider 571 is fixedly connected to the inner wall of the limiting tube 514, and the outer wall of the tension spring 576 on the side away from the slider 571 is fixedly connected to the inner wall of the limiting tube 514.

[0046] Specifically, under normal conditions without external pressure, the elastic spring 522 pushes the contact ring 523 inward to reset, driving the push rod 524 and the compression ring 525 to reset, releasing the compression constraint on the slider 571. Under the reset action of the tension spring 576 and the damping rod 575, the slider 571 moves closer to the axis of the limiting tube 514, causing the compression protrusion 573 at the bottom of the slider 571 to engage with the groove 517 on the outer wall of the rubber tube 516, thus squeezing and clamping the separator blade 45 at the axis of the limiting tube 514, forming a damping constraint on the separator blade 45. During this process, the inertial impact force generated by the rotation of the long shaft is offset by friction, avoiding the shaft from spinning freely and vibrating, thereby improving the overall operational stability of the equipment, reducing abnormal noise and structural wear, and extending the service life of the equipment. The remaining structure is the same as that in Embodiment 1.

[0047] Based on embodiments 1-2, the working principle of this invention is as follows: During actual operation, the control cabinet 2 outside the frame 1 controls the water pump 3 to pump the glycine magnesium production waste liquid into the separation component 4. The waste liquid is first introduced into the equipment through the inlet pipe 42, and then passes through the filter screen 47 into the packing tube 41. The packing tube 41 is filled with adsorption resin packing, which adsorbs and recovers magnesium ions in the waste liquid, thereby achieving the interception and enrichment of magnesium ions. During the operation of the equipment, the servo motor 44 drives the separating shaft blade 45 to rotate slightly. Unlike the continuously rotating structure, the separating shaft blade 45 only rotates at a short angle. Since the packing inside the packing tube 41 is spirally dispersed and the packing is evenly filled in the water flow area between the first filter plate 55 and the filter screen 47, the problem of water flow being difficult to reach the top of the packing tube 41 and the low utilization rate of the packing under the gravity of traditional equipment is improved, ensuring that the waste liquid and the packing are in full contact, and ensuring the basic recovery efficiency of magnesium ions.

[0048] After the waste liquid undergoes magnesium ion adsorption through the packing tube 41, it continues to flow and enters the drainage component 5. The water flows through the first filter plate 55 and the second filter plate 56 in sequence for double-layer filtration, effectively intercepting impurities and particles in the waste liquid. The filtered waste liquid finally flows into the water storage area formed by the outlet pipe 43, the second filter plate 56, the water blocking pipe 58 and the fixing ring 511 of the fixing component 51, thus completing the temporary storage of the waste liquid.

[0049] During the waste liquid treatment process, the servo motor 44 can drive the separator blade 45 to rotate in the forward direction. The threaded groove 46 on the outer wall of the separator blade 45 and the internal threaded plate 535 of the moving part 53 form a threaded transmission engagement, driving the internal threaded plate 535 to move as a whole. This, in turn, drives the sliding ring 531 to slide along the outer wall of the limiting tube 514. During the sliding process, the sliding ring 531 slides on the connecting tube 54 through the sliding hole 532. On the one hand, the sliding ring 531 drives the connecting tube 534 and the pressure ring 536 to move synchronously. On the other hand, it drives the blocking block 533 on the side wall to slide along the inner wall of the outlet pipe 43, gradually blocking and reducing the outlet of the outlet pipe 43. The water outlet flow area is expanded until the outlet is completely blocked. After the outlet is blocked, the liquid and gas inside the water storage area cannot be discharged. With the expansion of the structure, a local negative pressure environment is formed. The negative pressure suction is used to accelerate the flow speed of the upstream waste liquid and increase the waste liquid treatment throughput. At the same time, the water flow inside the water storage area can be introduced into the interior of the connecting pipe 54 through the hole of the connecting pipe 54. Meanwhile, the drainage area space enclosed by the fixed ring 511, the limiting pipe 514, the sliding ring 531 and the inner wall of the outlet pipe 43 is squeezed and contracted. With the outlet not completely blocked, the water pressure formed by the continuous water intake of the inlet pipe 42 is used to achieve high-pressure rapid drainage operation.

[0050] When the servo motor 44 drives the partition shaft 45 to rotate in the reverse direction, the threaded transmission drives the sliding ring 531 to move in the reverse reset direction, and the water storage area shrinks accordingly. At the same time, the blocking block 533 gradually moves away, thereby removing the obstruction and blockage of the outlet of the outlet pipe 43. Under the continuous action of the inlet water pressure, the liquid inside the water storage area is quickly squeezed and pushed, further accelerating the water flow through the connecting pipe 54 and the outlet pipe 43 for discharge. Through the cyclic switching of forward and reverse rotation of the servo motor 44, the alternating operation of negative pressure water intake and high pressure drainage inside the equipment can be realized, continuously disturbing the water flow and air flow inside the packing tube 41, quickly discharging the air left in the gaps between the packing, thereby accelerating the elimination of the airflow stagnation blind zone, so that the waste liquid can fully wet the entire packing area, thereby improving the effective utilization rate of the packing and stabilizing the magnesium ion recovery efficiency.

[0051] During the reciprocating sliding operation of the sliding ring 531, the internal shaft limiting structure of the equipment can be triggered simultaneously. When the sliding ring 531 moves, it drives the pressure ring 536 to approach the slider 571 of the limiting component 57. When the pressure ring 536 contacts the second pressing surface 574 of the slider 571, it can press the slider 571, causing it to slide away from the axis of the limiting tube 514 along the limiting groove 515. During the sliding process of the slider 571, the damping rod 575 and the tension spring 576 are stretched. At the same time, the pressing ring 525 is pressed through the first pressing surface 572 at the top, pushing the push rod 524 to slide outward along the movable hole 513 of the fixed ring 511, causing the contact ring 523 to move synchronously and press the spring piece 522. Since the fitting ring 521 is fixed on the fixed plate by the fixing pin 59 and the connecting hole 512, the spring piece 522 of the pressing component 52 shrinks and fits against the outer wall of the fitting ring 521.

[0052] Under normal conditions without external pressure, the elastic contact ring 523 of the spring plate 522 pushes the contact ring 523 inward to reset, driving the push rod 524 and the compression ring 525 to reset, releasing the compression constraint on the slider 571. Under the reset action of the tension spring 576 and the damping rod 575, the slider 571 moves closer to the axis of the limiting tube 514, causing the compression protrusion 573 at the bottom of the slider 571 to engage in the groove 517 on the outer wall of the rubber tube 516, squeezing and holding the dividing shaft leaf 45 at the axis of the limiting tube 514, forming a damping constraint on the dividing shaft leaf 45. During this process, the inertial impact force generated by the rotation of the long shaft is offset by friction, avoiding the shaft from spinning freely and shaking, thereby improving the overall operating stability of the equipment, reducing abnormal noise and structural wear, and extending the service life of the equipment.
