Description

Technical Field

[0001] This utility model relates to the field of recycling device technology, and in particular to a device for recycling extract. Background Technology

[0002] Electroplating enterprises typically generate electroplating wastewater containing metals such as copper and nickel during daily production. Extraction processes are commonly used to treat this wastewater, purifying, separating, and recovering the metals to reduce resource waste and environmental pollution. However, existing extraction processes generally involve mixing an extractant and a diluent. During extraction, the extractant is lost and reduced due to various factors, especially during back-extraction. If the back-extraction process is ineffective, significant amounts of extractant can be lost into the raffinate, severely impacting subsequent treatment of the electroplating wastewater. Furthermore, the high cost of extractants continuously increases the operating costs of the extraction process as they are lost, and this loss also has environmental impacts. Existing extractant wastewater recovery devices mostly involve filtration followed by settling the extract. Because the density of the extractant solvent is less than that of water, the extractant separates with the water, requiring manual separation for reuse. This method results in low precision in extractant recovery, the presence of impurities, poor extractant quality, and reduced extraction efficiency.

[0003] Chinese utility model patent CN217323741U discloses an extractant waste liquid recovery device, including a filter tank, an extraction tank, a cooler, and a stratification tank. The bottom of the filter tank is connected to a delivery pipe, the end of which is connected to the inlet of the extraction tank. A collection hood is installed at the top of the extraction tank, and a steam collector is installed at the top of the collection hood. An air inlet pipe is connected to the top of the steam collector, and a cooling pipe is connected to the end of the air inlet pipe. The cooling pipe is located inside the cooler, and its outlet is connected to a second outlet pipe, the end of which is connected to the stratification tank. By setting up a filter tank, extraction tank, cooler, and stratification tank, and stratifying the extractant through filtration, evaporation, and cooling liquefaction, the extractant in the waste liquid can be recovered and reused. This experimental device has a simple configuration, low manufacturing cost, greatly saves recovery costs, and improves the utilization rate of the extractant.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: The device collects the extractant from the upper layer of the stratification tank via an organic matter control valve fixed to the side wall of the stratification tank. In actual use, because the position of the organic matter control valve is fixed and the amount of extractant obtained in each extraction process is variable, the organic matter control valve may not be able to completely collect the extractant from the upper layer of the stratification tank. This results in a large amount of extractant remaining in the water at the lower layer of the stratification tank, which is detrimental to improving the user experience for operators. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a device for recovering extract.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an extractant recovery device includes an extraction tank, a stratification tank connected to the extraction tank, a cooler installed between the stratification tank and the extraction tank, and a filter tank connected to the extraction tank. A tempered glass plate for observing the stratified liquid levels inside the stratification tank is provided on the side wall of the stratification tank. A support rod is provided on the bottom surface of the stratification tank, and an aqueous phase pipe is provided on the bottom surface of the stratification tank. A first extractant pipe is provided on the side wall of the stratification tank. A connecting groove is formed on the inner bottom wall of the stratification tank, and a second extractant pipe is connected to the connecting groove. Sliding grooves are formed on the two opposite inner walls of the connecting groove. A sealing component for sealing the connecting groove is provided on the stratification tank.

[0007] By adopting the above technical solution, when workers need to recycle the extractant waste liquid, the waste liquid is first added through the inlet of the filter tank. It passes through two layers of activated carbon to filter out high-molecular impurities and finally flows into the extraction tank. Subsequently, the extraction tank is heated, causing the organic matter in the extractant waste liquid to vaporize. The steam collector at the top of the extraction tank collects the organic matter and steam, and the cooler cools the organic matter and steam, causing them to liquefy and enter the stratification tank. At this point, because the density of the organic matter (extractant) is less than the density of the steam (water), the organic matter and water separate into layers. Workers then simply need to open the first extractant pipe to move the organic matter layer above the water layer to the outside of the stratification tank. Further, workers need to open the aqueous phase pipe to move the water flow to the outside of the stratification tank. After the water is discharged, a certain amount of extractant remains in the stratification tank. Staff only need to open the sealing component and the second extractant tube to allow the residual extractant to be discharged through the second extractant tube.

[0008] Furthermore, the enclosed assembly includes a limiting spring fixed at one end to the inner wall of the chute, a baffle slidably disposed in the chute, and a connecting rope fixed at one end to the side wall of the baffle away from the limiting spring. The other end of the limiting spring is fixed to the side wall of the baffle, and the other end of the connecting rope extends to the outside of the stratification pool and is slidably connected.

[0009] By adopting the above technical solution, when the second extractant tube is not needed, the baffle needs to be kept closed, thus reducing the probability of water flowing into the connecting tank and improving the extractant content in the collected organic matter. When the extractant remains in the stratification tank, the operator loosens the connecting rope, allowing the baffle to move away from the rope under the action of the limiting spring, keeping the connecting tank open. Furthermore, the operator only needs to open the second extractant tube to allow the extractant to move out of the stratification tank, reducing the difficulty of collecting the extractant.

[0010] Furthermore, stabilizing grooves that communicate with the sliding groove are provided on the two inner walls opposite to each other of the connecting groove, and the two sides of the baffle are slidably connected to the two stabilizing grooves respectively.

[0011] Furthermore, a movable groove is provided on the side wall of the stratified pool, and a movable block is slidably disposed in the movable groove. The movable block is fixed to the end of the connecting rope away from the baffle.

[0012] By adopting the above technical solution, when the staff needs to move the connecting rope, the staff only needs to slide the moving block to make the end of the connecting rope away from the baffle move with the moving block, thereby reducing the difficulty of operation for the staff.

[0013] Furthermore, the side wall of the movable block is threaded with fixing bolts for fixing the movable block.

[0014] By adopting the above technical solution, when workers need to close the connecting groove, they can slide the moving block to move the fixed rod along the extension direction of the moving groove. When the connecting groove is completely closed, workers only need to rotate the fixing bolt to press the fixing bolt against the inner wall of the moving groove, thereby stabilizing the moving block and thus stabilizing the baffle.

[0015] Furthermore, a movable rope is fixed on the side wall of the baffle near the limiting spring, and a limiting block is fixed at the end of the movable rope. The end of the movable rope away from the baffle extends to the outside of the stratification pool and is slidably connected.

[0016] Furthermore, the moving rope is a moving rope made of rubber bands.

[0017] By adopting the above technical solution, when the baffle is stuck, the staff only needs to pull the limit block to make the moving rope follow the limit block, thereby moving the baffle away from the connecting rope, thus improving the staff's user experience.

[0018] Furthermore, the upper surface of the baffle is provided with a rubber sheet to improve the sealing effect of the baffle.

[0019] In summary, this utility model has the following beneficial effects: 1. In this application, when workers need to recycle the extractant waste liquid, the waste liquid is first added through the inlet of the filter tank, filtered through two layers of activated carbon to remove high-molecular impurities, and finally flows into the extraction tank. Subsequently, the extraction tank is heated to vaporize the organic matter in the extractant waste liquid. The steam collector at the top of the extraction tank collects the organic matter and steam, and the cooler cools the organic matter and steam, causing them to liquefy and enter the stratification tank. At this point, because the density of the organic matter (extractant) is less than the density of the steam (water), the organic matter and water separate into layers. Workers only need to open the first extractant pipe to move the organic matter layer above the water layer to the outside of the stratification tank. Further, workers need to open the aqueous phase pipe to move the water flow to the outside of the stratification tank. After the water is discharged, a certain amount of extractant remains in the stratification tank. Staff only need to open the sealing component and the second extractant tube to allow the residual extractant to be discharged through the second extractant tube; 2. In this application, when the worker does not need to use the second extractant tube, the worker must keep the baffle closed, thereby reducing the probability of water flowing into the connecting tank, which helps to increase the extractant content in the organic matter collected by the worker. When the worker needs to collect the extractant remaining in the stratification tank, the worker needs to loosen the connecting rope, which allows the baffle to move away from the connecting rope under the action of the limiting spring, thereby keeping the connecting tank open. Furthermore, the worker only needs to open the second extractant tube to allow the extractant to move out of the stratification tank through the second extractant tube, thereby reducing the difficulty for the worker to collect the extractant; 3. In this application, when the operator needs to close the connecting groove, the operator needs to slide the moving block, which will allow the fixed rod to move along the extension direction of the moving groove. When the connecting groove is completely closed, the operator only needs to rotate the fixing bolt, which will press the fixing bolt against the inner wall of the moving groove, thereby stabilizing the moving block and thus stabilizing the baffle.

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] like Figure 1-4 As shown in the illustration, this application discloses an extractant recovery device, comprising an extraction tank 1, a stratification tank 11, a cooler 12, a filter tank 13, a tempered glass plate 14, a support rod 2, an aqueous phase pipe 21, a first extractant pipe 3, a second extractant pipe 4, a sealing assembly 5, a moving block 7, a fixing bolt 8, a moving rope 81, a limiting block 82, and a rubber sheet 9. The stratification tank 11 is connected to the extraction tank 1. The support rod 2 is a rectangular rod structure, and multiple support rods 2 are arranged sequentially on the bottom surface of the stratification tank 11. The aqueous phase pipe 21 is disposed on the bottom surface of the stratification tank 11, and the first extractant pipe 3 is disposed on the side wall of the stratification tank 11. A connecting groove 31 is formed on the inner bottom wall of the stratification tank 11, and the second extractant pipe 4 is connected to the connecting groove 31.

[0024] The connecting groove 31 has two opposing inner walls with grooves 41. A sealing assembly 5 is installed on the layered pool 11 to seal the connecting groove 31. The sealing assembly 5 includes a limiting spring 51, a baffle 52, and a connecting rope 53. One end of the limiting spring 51 is fixed to the inner wall of the groove 41, and the other end is fixed to the side wall of the baffle 52. The baffle 52 is a rectangular plate structure and is slidably disposed within the groove 41. One end of the connecting rope 53 is fixed to the side wall of the baffle 52 away from the limiting spring 51, and the other end extends to the outside of the layered pool 11 and is slidably connected.

[0025] When the second extractant tube 4 is not needed, the baffle 52 should be kept closed to reduce the probability of water flowing into the connecting tank 31, thereby increasing the extractant content in the collected organic matter. When the extractant remains in the stratification tank 11, the baffle 52 should be released, allowing it to move away from the baffle 53 under the action of the limiting spring 51, thus keeping the connecting tank 31 open. Furthermore, the extractant can be moved out of the stratification tank 11 simply by opening the second extractant tube 4, reducing the difficulty of collecting the extractant.

[0026] On the two inner walls opposite to each other of the connecting groove 31, there are stabilizing grooves 6 that communicate with the sliding groove 41. The two sides of the baffle 52 are slidably connected to the two stabilizing grooves 6 respectively. The side wall of the layered pool 11 is provided with a moving groove 61. The moving block 7 is a rectangular block structure. The moving block 7 is slidably disposed in the moving groove 61, and the moving block 7 is fixed to the end of the connecting rope 53 away from the baffle 52.

[0027] When the operator needs to move the connecting rope 53, the operator only needs to slide the moving block 7 to make the end of the connecting rope 53 away from the baffle 52 move with the moving block 7, thereby reducing the difficulty of operation for the operator.

[0028] The fixing bolt 8 is threaded onto the side wall of the movable block 7 to fix the movable block 7. When the operator needs to close the connecting groove 31, the operator needs to slide the movable block 7, which will allow the fixing rod 71 to move along the extension direction of the moving groove 61. When the connecting groove 31 is completely closed, the operator only needs to rotate the fixing bolt 8 to make the fixing bolt 8 press against the inner wall of the moving groove 61, thereby stabilizing the movable block 7 and thus stabilizing the baffle 52.

[0029] One end of the moving rope 81 is fixed to the side wall of the baffle 52 near the limiting spring 51. The limiting block 82 is a rectangular block structure and is fixed to the end of the moving rope 81. The end of the moving rope 81 away from the baffle 52 extends to the outside of the stratification pool 11 and is slidably connected. The moving rope 81 is made of rubber band. In actual use, the connecting rope 53 and the moving rope 81 have sealing structures such as sealing gaskets at the points where they pass through the stratification pool 11.

[0030] When the baffle 52 is stuck, the staff only needs to pull the limit block 82 to make the moving rope 81 move with the limit block 82, thereby moving the baffle 52 away from the connecting rope 53, thus improving the staff's user experience.

[0031] To improve the sealing effect of the baffle 52, a rubber sheet 9 is provided on the upper surface of the baffle 52.

[0032] The operating principle of the extractant recovery device in this embodiment is as follows: When the operator needs to recycle the extractant waste liquid, the waste liquid is first added through the inlet of the filter tank 13. It passes through two layers of activated carbon to filter out high-molecular-weight impurities and finally flows into the extraction tank 1. Subsequently, the operator heats the extraction tank 1, causing the organic matter in the extractant waste liquid to vaporize. The steam collector at the top of the extraction tank 1 collects the organic matter and steam, and the cooler 12 cools the organic matter and steam, causing them to liquefy and enter the stratification tank 11. At this point, because the density of the organic matter (extractant) is less than the density of the steam (water), the organic matter and water separate into layers. The operator then simply opens the first extractant pipe 3, allowing the organic matter layer above the water layer to move along the first extractant pipe 3 to the outside of the stratification tank 11. Further, the operator opens the aqueous phase pipe 21, allowing the water flow to move along the aqueous phase pipe 21 to the outside of the stratification tank 11. After the water is discharged, a certain amount of extractant remains in the stratification tank 11. Staff only need to open the sealing component 5 and the second extractant tube 4 to allow the residual extractant to be discharged through the second extractant tube 4.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
