DETAILED DESCRIPTION

[0031] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 11 As shown:

[0033] Embodiment 1: The present invention provides a working fluid circulation and regeneration device for producing hydrogen peroxide by anthraquinone method, comprising: an adsorption tank mechanism 1, comprising an adsorption tank assembly 11, a cover assembly 12 embedded in the adsorption tank assembly 11, and a positioning assembly 13 installed on the adsorption tank assembly 11, wherein the positioning assembly 13 can position the cover assembly 12; an adsorption mechanism 2, comprising an adsorption assembly 21 slidably embedded in the adsorption tank assembly 11, and a grille slide plate 22 arranged on the adsorption assembly 21;

[0034] Among them, when it is necessary to adsorb the metal ions inside the working fluid, the working fluid is introduced from the bottom of the adsorption tank assembly 11. After the working fluid passes through the adsorption assembly 21, the metal ions will be adsorbed, and at the same time, the working fluid will be discharged from the baffle assembly 12; when the adsorption assembly 21 needs to be replaced, the staff can pull out the adsorption assembly 21, and after opening the grille slide plate 22, the staff can quickly replace the internal activated carbon plate, which greatly facilitates the replacement efficiency of the staff; after the control positioning assembly 13 releases the positioning of the baffle assembly 12, the staff can easily remove the baffle assembly 12, which is convenient for use.

[0035] Specifically, the adsorption tank assembly 11 includes an adsorption tank body 111, the bottom of which is fixedly connected to a liquid inlet pipe port 112, a sliding groove 113 is also opened in the middle of the adsorption tank body 111, a plurality of supporting legs 114 are also fixedly connected to the outer side of the bottom of the adsorption tank body 111, and a positioning frame 115 is also fixedly connected to the upper edge of the adsorption tank body 111.

[0036] Specifically, the blocking cover assembly 12 includes a blocking cover body 121, the upper side of which is fixedly connected to a liquid outlet 122, and the outer side of the blocking cover body 121 is also fixedly connected to a positioning ear 123; the positioning assembly 13 includes an L-shaped positioning block 131, one side of the L-shaped positioning block 131 is fixedly connected to a spring 132, and a spring 2 133 is also arranged inside the adsorption tank body 111.

[0037] Specifically, the positioning ear 123 is limited and slidably embedded in the positioning frame 115, the spring 132 can drive the L-shaped positioning block 131 to move outward, the L-shaped positioning block 131 can limit the positioning ear 123, and the spring 2 133 drives the cover body 121 to move upward.

[0038] As can be seen from the above, the adsorption tank body 111 is firmly placed on the ground through the support legs 114, the liquid inlet pipe port 112 and the liquid outlet pipe port 122 are correctly connected to the corresponding pipeline system, and the baffle body 121 is placed above the adsorption tank body 111, ensuring that the positioning ear 123 is aligned and limitedly slidably embedded in the positioning frame 115. At this time, due to the elastic force of the spring 132, the L-shaped positioning block 131 will move outward and clamp the positioning ear 123 to achieve the initial positioning of the baffle assembly 12, and the spring 2 133 is installed inside the adsorption tank body 111 to provide an upward driving force to assist the separation of the baffle body 121; the liquid to be introduced into the adsorption tank body 111 through the liquid inlet pipe port 112 The treated working fluid flows through the adsorption component 21, and the metal ions and other impurities therein are adsorbed by the adsorption material. The purified working fluid is discharged through the liquid outlet 122 on the baffle body 121 and enters the subsequent process flow; the L-shaped positioning block 131 is controlled and the spring 132 is compressed to release the limitation on the positioning ear 123. When the positioning ear 123 is no longer limited, the baffle component 12 can be easily moved upward and separated from the adsorption tank body 111 with the assistance of the spring 2 133; the staff can pull out the adsorption component 21, open it through the grille slide 22 and replace the internal activated carbon plate and other adsorption materials; after the replacement is completed, the new adsorption component 21 is reinstalled in the adsorption tank body 111.

[0039] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the adsorption assembly 21 includes an adsorption frame body 211, one side of the adsorption frame body 211 is fixedly connected with an outer pull-out plate 212, the outer side of the adsorption frame body 211 is also fixedly connected with a guide bar 213, and the interior of the adsorption frame body 211 is also provided with an activated carbon plate 214.

[0040] Specifically, the activated carbon plate 214 is limited and embedded in the interior of the adsorption frame body 211, and the grille slide plate 22 is limited and slidably embedded on the adsorption frame body 211. The grille slide plate 22 can limit the activated carbon plate 214, and the adsorption frame body 211 is limited and slidably embedded in the sliding groove 113.

[0041] As can be seen from the above, the adsorption frame body 211 is aligned with the sliding groove 113 on the adsorption tank body 111, and the adsorption frame body 211 is pushed in along the direction of the sliding groove 113 until it is completely limited and slid into the sliding groove 113. At the same time, the guide bar 213 will play a guiding role to ensure that the adsorption frame body 211 enters the sliding groove 113 smoothly and accurately; the grille slide plate 22 is removed from the adsorption frame body 211 to expose the installation position of the activated carbon board 214, and the new or prepared activated carbon board 214 is limited and embedded in the interior of the adsorption frame body 211 to ensure that the activated carbon board 214 is stable and in the correct position.

[0042] Close the grille slide 22 and insert its limit sliding card back into the adsorption frame body 211 , then move the grille slide 22 to ensure that the grille slide 22 effectively limits and fixes the activated carbon plate 214 .

[0043] Embodiment 3

[0044] This embodiment is basically the same as the previous embodiment, except that the first vertical shaft 3 is rotatably mounted on both sides of the sliding groove 113 on the adsorption tank assembly 11, and the top and bottom ends of the first vertical shaft 3 are fixed with fan-shaped positioning plates 301. When the fan-shaped positioning plate 301 is rotated to the side close to the adsorption frame body 211, the adsorption frame body 211 can be clamped from the top and bottom ends. The fan-shaped positioning plate 301 is provided with a chamfer close to the adsorption frame body 211. The fan-shaped positioning plate 301 is made of rubber, and the spacing between the upper and lower pairs of fan-shaped positioning plates 301 is less than the thickness of the fan-shaped positioning plate 301.

[0045] By rotating the fan-shaped positioning plate 301, the adsorption frame body 211 can be clamped, so that the adsorption frame body 211 is installed more stably, the overall airtightness of the device is improved, and liquid leakage is prevented.

[0046] Among them, a first gear 302 is fixed on the outside of the first vertical shaft 3, and two first racks 303 arranged parallel to each other are slidably installed in the adsorption tank body 111. The ends of the two first racks 303 away from each other are fixed with second racks 304, and the second racks 304 are meshed with the first gear 302. The ends of the two first racks 303 close to each other are provided with springs 305;

[0047] In the absence of external force, spring three 305 pulls the two first racks 303 to move closer to each other, and then can drive the first vertical axis 3 to rotate until the fan-shaped positioning plate 301 is separated from the adsorption frame body 211 through the engagement of the second rack 304 with the first gear 302, and the adsorption frame body 211 can be easily pulled out at this time.

[0048] Among them, a second vertical shaft 4 is rotatably installed in the adsorption tank body 111, the second vertical shaft 4 is located between the two first racks 303, and a second gear 401 is fixed to the outside of the second vertical shaft 4, the two first racks 303 are respectively meshed with the second gear 401 from both sides of the second gear 401, a linkage column 402 is fixed to the top of the second vertical shaft 4, a spiral guide groove 403 is opened on the outside of the linkage column 402, a lifting ring 405 is provided on the outside of the linkage column 402, the lifting ring 405 is guided and installed by a guide rod 404, a limiting rod 406 is fixed on the inner wall of the lifting ring 405, the limiting rod 406 extends into the spiral guide groove 403, a pressure plate 407 is fixed to the outer ring of the lifting ring 405, and a pressing rod corresponding to the pressure plate 407 is fixed to the bottom end of the baffle cover assembly 12;

[0049] When the suction frame body 211 is plugged into place, during the process of covering the baffle assembly 12, the pressing rod will press down the pressing plate 407, and then press down the lifting ring 405. Since the limit rod 406 slides along the spiral guide groove 403, it can drive the second vertical shaft 4 to rotate, and then drive the two first racks 303 to move relative to each other through the engagement of the first rack 303 and the second gear 401. At this time, the spring three 305 is stretched, and through the engagement of the second rack 304 with the first gear 302, the first vertical shaft 3 is driven to rotate to the state where the fan-shaped positioning plate 301 clamps the suction frame body 211. Through the linkage method, when the baffle assembly 12 is installed in place, the fan-shaped positioning plate 301 will automatically switch to the state of clamping the suction frame body 211. When the baffle assembly 12 is picked up, the fan-shaped positioning plate 301 will automatically switch to the state of being separated from the suction frame body 211, which is more convenient to use. On the one hand, it enhances the stability and airtightness of the installation of the suction frame body 211, and on the other hand, it will not increase the difficulty of disassembly and assembly.
