[0029] Example 1
[0030] A loosening device for an ion exchange column, as described in this embodiment, Figs. 1-2 As shown, the device includes a base plate 1 and a controller, which can be a Siemens SIMATI C S7-1200. The base plate 1 has a sleeve 4 for placing an ion exchange column 2 and a hinged door 3 on one side. The inner side of the sleeve 4 has a fixing mechanism and an ultrasonic mechanism. Above the sleeve 4 is a mounting plate 5 that can move in the vertical direction. The mounting plate 5 has a stirring mechanism. The base plate 1 also has a backwashing mechanism. The bottom interface of the ion exchange column 2 is detachably connected to the outlet of the backwashing mechanism through a first connecting pipe 6. The top interface of the ion exchange column 2 is detachably connected to the wastewater end of the backwashing mechanism through a second connecting pipe 7. The ultrasonic mechanism, stirring mechanism, and backwashing mechanism are all electrically connected to the controller.
[0031] In practical use, the operator first opens the opening and closing door 3, places the ion exchange column 2 inside the sleeve 4 and fixes it in place using the fixing mechanism, then connects the bottom interface of the ion exchange column 2 to the first connecting pipe 6 and the top interface of the ion exchange column 2 to the second connecting pipe 7; closes the opening and closing door 3 and starts the backwashing mechanism through the controller. The backwashing mechanism sends backwash liquid through the first connecting pipe 6 from the bottom of the ion exchange column 2 and out from the top of the ion exchange column 2, and then through the second connecting pipe 7 into the wastewater end of the backwashing mechanism, thereby achieving backwashing and loosening of the resin bed inside the ion exchange column 2. When agitating the resin bed of ion exchange column 2, the second connecting pipe 7 is first disconnected from the top interface of ion exchange column 2. Then, the mounting plate 5 is moved downwards by the controller, allowing the agitator to enter the interior of ion exchange column 2 from the top. The depth of the agitator's insertion into the resin bed is controlled by adjusting the downward movement of the mounting plate 5. The agitator is then activated to mechanically loosen the resin bed of ion exchange column 2. When ultrasonically treating the resin bed of ion exchange column 2, the operator activates the ultrasonic mechanism via the controller to ultrasonically loosen the resin bed inside ion exchange column 2. This device integrates backwashing, mechanical agitation, and ultrasonic loosening technologies to improve the loosening effect of the resin bed in ion exchange column 2.
[0032] It is worth mentioning that staff can choose or combine various loosening techniques according to the situation, making it highly practical. For example, when the pressure drop in the resin bed increases significantly (such as a decrease in flow rate of more than 50%), backwashing can be used for loosening; when local agglomeration occurs in the resin bed (such as resin caking at the top), mechanical stirring can be used for loosening; and when stubborn agglomeration occurs (such as bio-enzyme adhesion), ultrasonic loosening can be used.
[0033] In this embodiment, as Figs. 1-2 As shown, the stirring mechanism includes a stirring column 8 disposed below the mounting plate 5. The stirring column 8 is rotatably connected to the mounting plate 5 and is driven to rotate by a motor 9 on the mounting plate 5. Multiple sets of blades are arranged vertically on the sidewall of the stirring column 8. Each blade set includes multiple stirring blades 10 horizontally and evenly distributed around the sidewall of the stirring column 8. The stirring blades 10 can be made of flexible material (e.g., polytetrafluoroethylene to avoid scratching the column wall). For example, the stirring column 8 is vertically disposed above the ion exchange column 2.
[0034] In actual use, the controller controls the mounting plate 5 to move downwards, and the stirring column 8 enters the interior of the ion exchange column 2 through the interface at the top of the column. The controller controls and adjusts the insertion depth into the resin bed (5-10 cm of resin on the surface to avoid damaging the deep structure). Then, the controller starts the motor 9 to rotate slowly, and the stirring blade 10 stirs the resin bed.
[0035] In this embodiment, as Figs. 1-2 As shown, a plurality of telescopic cylinders electrically connected to the controller are vertically arranged on the top of the base plate 1. The telescopic cylinders are evenly distributed around the outer side of the sleeve 4. The cylinder body 11 of the telescopic cylinder is fixedly connected to the base plate 1, and the piston 12 of the telescopic cylinder is fixedly connected to the mounting plate 5.
[0036] In practical use, the extension and retraction of the telescopic cylinder piston 12 is controlled by the controller, thereby controlling the lifting and lowering of the mounting plate 5.
[0037] In this embodiment, as Figs. 1-2 As shown, the backwashing mechanism includes a pump body 13 disposed on the substrate 1. The pump body 13 is a peristaltic pump. The water inlet of the pump body 13 is connected to the backwash liquid storage tank 14 disposed on the substrate 1. The water outlet of the pump body 13 is the water outlet of the backwashing mechanism. The water outlet of the pump body 13 is connected to the first connecting pipe 6 disposed at the bottom of the inner side of the sleeve 4 through the first channel 15 inside the substrate 1. The wastewater end of the backwashing mechanism includes a waste liquid collection tank 16 disposed on the substrate 1. The water inlet of the waste liquid collection tank 16 is connected to one end of the second connecting pipe 7. The other end of the second connecting pipe 7 is detachably connected to the top interface of the ion exchange column 2.
[0038] In practical use, the pump body 13 draws the backwash liquid from the backwash liquid storage tank 14 through the first channel 15 into the first connecting pipe 6 at the bottom of the inner side of the sleeve 4, and then into the ion exchange column 2 from the bottom of the first connecting pipe 6 and the ion exchange column 2, and exits from the top of the ion exchange column 2. Then, it enters the waste liquid collection tank 16 through the second connecting pipe 7, thereby achieving backwashing and loosening of the resin bed inside the ion exchange column 2.
[0039] In this embodiment, as Figs. 1-2 As shown, the inlet of the waste liquid collection tank 16 is connected to the outlet of the second channel 18 located in the mounting plate 5 via a hose 17. The inlet of the second channel 18 is located at the bottom of the mounting plate 5. One end of the second connecting pipe 7 is connected to the bottom of the mounting plate 5 and sleeved outside the inlet of the second channel 18. The other end of the second connecting pipe 7 is detachably sleeved on the interface at the top of the ion exchange column 2. The second connecting pipe 7 is a sealed corrugated pipe.
[0040] The above technical solution satisfies the connection between the interface at the top of the ion exchange column 2 and the inlet of the waste liquid collection tank 16. Furthermore, since the second connecting pipe 7 is a sealed corrugated pipe, the interface at the top of the ion exchange column 2 remains in a sealed connection with the inlet of the second channel 18 during the lifting and lowering movement of the mounting plate 5.
[0041] In this embodiment, as Figs. 1-2 As shown, the stirring column 8 is sleeved inside the second connecting pipe 7.
[0042] Through the above technical solution, when the stirring column 8 extends into the ion exchange column 2, the top interface of the ion exchange column 2 is always in a sealed state, which effectively prevents liquid leakage during stirring. Furthermore, since the second connecting pipe 7 is a sealed bellows, the internal pressure of the stirring column 8 remains stable when it rotates, and the ion exchange column 2 is in a dynamically sealed state.
[0043] In this embodiment, as Figs. 1-2 As shown, the first connecting pipe 6 is a sealed bellows pipe.
[0044] The above technical solution facilitates the connection of the first connecting tube 6 to the bottom interface of the ion exchange column 2 by the staff.
[0045] In this embodiment, as Figs. 1-2 As shown, the fixing mechanism includes two arc-shaped plates 19 fixedly disposed inside the sleeve 4. The two arc-shaped plates 19 are vertically disposed, and the distance between them matches the distance between the top of the upper flange and the bottom of the lower flange of the ion exchange column 2. The opening direction of the arc-shaped plates 19 faces the position of the opening and closing door 3.
[0046] In practical use, the ion exchange column 2 enters the arc plate 19 through the opening of the arc plate 19, and the bottom of its lower flange is supported above the second arc plate 19, while its upper flange also abuts against the bottom of the first arc plate 19, thereby fixing the ion exchange column 2.
[0047] In this embodiment, as Figs. 1-2 Figs. 1-2 As shown, the ultrasonic mechanism includes an ultrasonic device group arranged vertically inside the sleeve 4. The ultrasonic device group is disposed between the two arc-shaped plates 19, so that the ultrasonic device can be aligned with the tube wall of the ion exchange column 2. The ultrasonic device group includes ultrasonic generators 20 evenly distributed around the inner wall of the sleeve 4.
[0048] In practical use, first apply a coupling agent (silicone grease or water-based gel) between the probe 21 of the ultrasonic generator 20 and the column wall of the ion exchange column 2 to reduce energy loss caused by air gaps. Then start the ultrasonic generator 20 to loosen the resin bed through ultrasonic waves.
[0049] Example 2
[0050] In Embodiment 2, unlike the embodiments described above, the bottom of the substrate 1 is provided with casters to facilitate the movement of the device.
[0051] The specific operating principle of this device
[0052] When backwashing the resin bed of the ion exchange column 2, the backwashing mechanism is activated by the controller. The backwashing mechanism sends the backwash liquid into the bottom of the ion exchange column 2 through the first connecting pipe 6 and out of the top of the ion exchange column 2. Then, it enters the wastewater end of the backwashing mechanism through the second connecting pipe 7, thereby achieving backwashing and loosening of the resin bed inside the ion exchange column 2.
[0053] When stirring the resin bed of the ion exchange column 2, the second connecting pipe 7 is first disconnected from the top interface of the ion exchange column 2. Then, the mounting plate 5 is moved downward by the controller, so that the stirring mechanism enters the interior of the ion exchange column 2 from the top. The depth of the stirring mechanism into the resin bed is controlled by controlling the downward movement of the mounting plate 5. Then, the stirring mechanism is started to stir, thereby realizing the mechanical stirring and loosening of the resin bed of the ion exchange column 2.
[0054] When ultrasonically treating the resin bed of ion exchange column 2, the operator activates the ultrasonic mechanism through the controller to ultrasonically loosen the resin bed inside ion exchange column 2.
[0055] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
