Description

Technical Field

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Combine the following Figures 1 to 3 , describing an extraction device with strong sealing performance in an embodiment of the utility model.

[0033] An extraction device with strong sealing performance comprises a cylinder body 1, a first drainage pipe 2 and a second drainage pipe 3, wherein the cylinder body 1 is provided with a first vertical partition plate 11 and a second vertical partition plate 12 from left to right, and the first partition plate 11 and the second partition plate 12 divide the interior of the cylinder body 1 into a stirring zone 4, a stratification zone 5 and a discharge zone 6 from left to right;

[0034] The cylinder 1 is used to introduce two liquids and stir and mix them to form a mixed liquid. The stirring area 4 is used to store the mixed liquid. The top of the stirring area 4 is connected to the top of the stratification area 5. The stratification area 5 is used to stratify the mixed liquid to form an upper layer of liquid and a lower layer of liquid. The bottom of the stratification area 5 is connected to the bottom of the discharge area 6.

[0035] The first drain pipe 2 is connected to the discharge area 6, and the first drain pipe 2 is used to discharge the lower layer liquid; the top of the second partition plate 12 is provided with an upper layer drain hole, and the second drain pipe 3 is connected to the stratification area 5 through the upper layer drain hole, and the second drain pipe 3 is used to discharge the upper layer liquid;

[0036] A cover plate is provided on the top of the cylinder body 1 , and the cover plate is used to seal the top of the cylinder body 1 .

[0037] In the present scheme, a highly sealed extraction device can introduce two liquids into the stirring zone 4 and stir the two liquids to form a mixed liquid, wherein the two liquids are an extractant and an etching liquid. The water level of the mixed liquid in the stirring zone 4 gradually rises, and it can flow from the top of the first partition plate 11 to the stratification zone 5, and the stratification zone 5 stratifies the mixed liquid so that the top of the stratification zone 5 is the upper layer of liquid and the bottom is the lower layer of liquid. Then, as the water level rises, the upper layer of liquid is discharged from the second drain pipe 3, and the lower layer of liquid is discharged from the first drain pipe 2 of the discharge zone 6, thereby completing the extraction process.

[0038] During the extraction process, when the mixed liquid flows to the discharge area 5, ammonia is easily volatilized outward. Since the molecular weight of ammonia is small, it is easy to float and gather on the top wall of the discharge area 6. A cover plate is provided on the top of the cylinder body 1, so that the top of the cylinder body 1 has a better sealing effect, which effectively prevents ammonia from being discharged to the outside from the top of the cylinder body 1, and solves the problem of waste gas overflowing from the extraction device during the traditional extraction process.

[0039] The stirring zone is provided with a first liquid water inlet pipe 41, a second liquid water inlet pipe 42 and a stirring pipe 43, the input end of the first liquid water inlet pipe 41 is connected to an external pipeline, and the output end of the first liquid water inlet pipe 41 is connected to the stirring pipe 43; the input end of the second liquid water inlet pipe 42 is connected to an external pipeline, and the output end of the second liquid water inlet pipe 42 is connected to the stirring pipe 43;

[0040] The cylinder body 1 is provided with a stirring component 44 in the stirring zone 4 , and the stirring end of the stirring component 44 extends into the stirring tube 43 , and the stirring component 44 is used to stir the liquid in the stirring tube 43 . The bottom of the stirring tube 43 is provided with multiple openings 430 , and the multiple openings 430 are connected to the stirring zone 4 .

[0041] The etching liquid flows into the stirring tube 43 through the first liquid inlet pipe 41, and the extraction liquid flows into the stirring tube 43 through the second liquid inlet pipe 42, and then the stirring assembly 44 stirs the liquid in the stirring tube 43 so that the etching liquid and the extraction liquid are fully mixed to form a mixed liquid. Since the mixed liquid after being stirred evenly is easy to volatilize waste gas to the outside, but in this solution, there is a large amount of liquid in the first liquid inlet pipe 41, the second liquid inlet pipe 42 and the stirring tube 43, making it difficult for the waste gas to be discharged from the input end of the first liquid inlet pipe 41 and the second liquid inlet pipe 42 to the outside of the cylinder body 1.

[0042] The stirring assembly 44 includes a driving member 441 and a stirring rod 442 . The driving member 441 is installed on the top of the cylinder body 1 . The driving end of the driving member 441 is connected to the stirring rod 442 . The end of the stirring rod 442 extends into the stirring tube 43 .

[0043] The driving member 441 is started, and the driving member 441 can drive the stirring rod 442 to rotate in the stirring tube 43, so that the liquid in the stirring tube 43 forms a vortex, thereby fully mixing the first liquid and the second liquid to form a mixed liquid.

[0044] An L-shaped plate 51 is provided at the top of the stratified area 5 near the discharge area 6, and the horizontal end of the L-shaped plate 51 is fixedly connected to the second partition plate 12. The L-shaped plate 51 and the second partition plate 12 form a storage space for the upper liquid. The top of the stratified area 5 is connected to the top of the storage space, and the input end of the second drain pipe 3 is connected to the storage space.

[0045] In order to ensure that the lower layer of liquid cannot flow into the storage space of the upper layer of liquid, a small gap is left between the vertical end of the L-shaped plate 51 and the inner wall of the cylinder 1, so that the upper layer of liquid located at the top of the stratified area 5 can flow from the gap into the storage space of the upper layer of liquid. Since the input end of the second drain pipe 3 is connected to the storage space, the upper layer of liquid can be discharged from the cylinder 1 through the second drain pipe 3.

[0046] The bottom of the stratification area 5 is connected to the bottom of the discharge area 6, so that the lower layer of liquid can flow into the discharge area 6 and then be discharged out of the cylinder body 1 through the first drain pipe 2. Therefore, the height of the lower layer of liquid is dynamically changing, and it is difficult to flow from the gap between the L-shaped plate 51 and the cylinder body 1 into the accommodation space, thereby completely separating the upper layer of liquid and the lower layer of liquid.

[0047] The first drain pipe 2 is vertically installed in the discharge area 6 , and an input end of the first drain pipe 2 is located between the upper drainage hole and the bottom of the second partition plate 12 .

[0048] In the early stage of extraction, the mixed liquid flows from the bottom of the second partition plate 12 to the discharge area 6, and then stratifies in the discharge area 6, so that a small amount of upper liquid is located in the discharge area 6. As the water level of the mixed liquid increases, when the water level of the mixed liquid is higher than the bottom wall of the second partition plate 12 and stratification begins, the second partition plate 12 can limit the flow path of the upper liquid, so that the upper liquid can only flow in the stratification area 5.

[0049] Since the bottom of the stratification area 5 is connected to the bottom of the discharge area 6, the water level of the stratification area 5 is consistent with the water level of the discharge area 6. At this time, the present solution defines the height of the input end of the first drain pipe 2. When the upper layer of liquid flows into the accommodation space, it means that the water level in the discharge area 6 is higher than the input end of the first drain pipe 2, and the lower layer of liquid can be discharged from the first drain pipe 2 to the outside of the cylinder 1.

[0050] A vertical slow flow plate 52 is provided on one side of the layered zone 5 close to the first partition plate 11, and the slow flow plate 52 is provided with a plurality of slow flow holes.

[0051] The slow flow plate 52 slows down the speed of the mixed liquid in the entrance of the stratification zone 5 through multiple slow flow holes, so that the mixed liquid can enter the water pool smoothly, avoiding excessive impact and turbulence, thereby reducing the impact force of the mixed liquid on the bottom of the cylinder body 1 and protecting the structural safety of the cylinder body 1.

[0052] Among them, the multiple slow flow plates 52 can increase the residence time of the mixed liquid in the stratification zone 5, thereby increasing the contact time between the first liquid and the second liquid, which is helpful to improve the extraction efficiency and make the extraction process more complete.

[0053] The stratified area 5 is distributed with a plurality of horizontal baffles 53 , and two sides of the baffles 53 are connected to the inner wall of the cylinder body 1 .

[0054] The baffle 53 further slows down the flow rate of the mixed liquid, allowing the mixed liquid to flow more smoothly in the stratification zone 5, so that different liquids are better separated, and the extraction effect is further improved. By properly setting the position and angle of the baffle 53, the stratification effect can be optimized and the extraction purity can be improved.

[0055] By setting a plurality of baffles 53 in the stratification zone 5, the flow field distribution in the stratification zone 5 can be further optimized, so that the mixed liquid flows more evenly and avoids the phenomenon of local flow velocity being too fast or too slow, thereby improving the extraction efficiency and quality, thereby ensuring that the mixed liquid is stratified in the stratification zone 5 to obtain an upper layer of liquid and a lower layer of liquid.

[0056] A horizontal plate 54 is provided on the top of the first partition plate 11 , and the horizontal plate 54 abuts against the top of the slow flow plate 52 . A vertical plate 55 is fixedly installed on the end of the horizontal plate 54 away from the first partition plate 11 , and the slow flow plate 52 is located between the first partition plate 11 and the vertical plate 55 .

[0057] The stratification area 5 stratifies the mixed liquid so that the upper liquid is an oily liquid and the lower liquid is an etching waste liquid. When the lower liquid volatilizes ammonia gas outward, the upper liquid can play the role of an oil seal to prevent the ammonia gas from diffusing to the top of the stratification area 5. When the water level of the upper liquid is higher than the bottom of the vertical plate 55, the vertical plate 55 can guide the mixed liquid to flow downward, thereby reducing the volatilization of ammonia gas when the mixed liquid enters the stratification area 5.

[0058] The horizontal plate 54 and the vertical plate 55 cooperate together to suppress the leakage of ammonia gas, making it difficult for the ammonia gas to float and gather on the top wall of the stratified area 5, thereby further reducing the overflow of ammonia gas.

[0059] In addition, a sealing cover 61 is provided at the top of the discharge area 6. The sealing cover 61 is in the shape of a Chinese character "X". In order to further improve the sealing effect of the sealing cover 61, water can be added to the gap between the sealing cover 61 and the side wall of the cylinder body to form a serpentine water flow. When ammonia volatilizes from the sealing cover, it will dissolve in the water outside the sealing cover, so that the sealing cover has a better sealing effect, further reducing the discharge of ammonia from the top of the discharge area 6.

[0060] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
