Description

Technical Field

[0001] The utility model relates to the technical field of glufosinate impurity separation, in particular to a device for flotation separation of glufosinate impurities. Background Technique

[0002] Glufosinate has the characteristics of broad herbicide spectrum, low toxicity, high activity and good environmental compatibility. The speed of its active effect is slower than paraquat and better than glyphosate. During the production process of glufosinate, waste residues mainly composed of aluminum chloride and sodium chloride will be generated. The general method of flotation separation of glufosinate impurities is only to separate by specific gravity. The separation efficiency by only gravity is low, and the separation effect is poor, which affects the efficiency of subsequent purification work. For example, the utility model patent with the application number CN202121825847.5 discloses a chemical centrifugal separation device, including an installation platform and a separation chamber. The bottom of the installation platform is fixedly installed with support feet, and the top of the installation platform is fixedly installed with two groups of shock absorbers. This device uses a one-way bearing to drive the overall rotation of the outer separation chamber, which is beneficial to the centrifugal separation of two liquids with different densities and expands the use range of the device. However, during the separation process, the stratification effect of the separation of the positions close to each other of the internal raw materials is not obvious, affecting the separation effect.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0023] Please refer to Figures 1-6, the present utility model provides a device for flotation separation of glufosinate impurities, which includes a separation tank 1 and a collection cylinder 13. A support leg frame 3 is installed at the bottom of the separation tank 1. A bottom discharge pipe 4 is installed at the bottom of the support leg frame 3 and at the middle position. A feeding cylinder 2 is installed at the top of the separation tank 1. A bottom opening 5 is formed on the outer wall of the feeding cylinder 2. A diversion groove 6 is installed on the outer wall of the feeding cylinder 2 and at the position outside the bottom opening 5. A positioning opening 7 is formed on the outer wall of the separation tank 1 and at the position above the diversion groove 6. A clamping groove 8 is formed at the top of the outer side wall of the diversion groove 6. A collection pipe 9 is inserted into the positioning opening 7 and the clamping groove 8. One end of the collection pipe 9 extending above the diversion groove 6 has a collection opening 10 on its outer wall. A connecting elbow 11 is installed at the outer end of the collection pipe 9. A conveying vertical pipe 12 is installed at the bottom of the connecting elbow 11. A connecting sleeve 15 is movably sleeved at the bottom of the conveying vertical pipe 12. A connecting pipe head 14 is installed at the top of the collection cylinder 13. The bottom end of the connecting sleeve 15 is threadedly connected to the connecting pipe head 14.

[0024] Further, the diversion groove 6 is spiral. The top end of the diversion groove 6 bends inward and is installed on the outside of the bottom opening 5. The solution inside the feeding cylinder 2 flows into the diversion groove 6 through the bottom opening 5, and the solution flows downward along the diversion groove 6.

[0025] Further, the collection opening 10 is formed on the surface of the collection pipe 9 and at the side close to the upper end of the diversion groove 6. The upper-layer liquid of the liquid flowing down from the upper side of the diversion groove 6 is collected through the collection opening 10.

[0026] Further, there are several collection pipes 9, and the distance between the collection pipe 9 and the inner wall of the bottom of the diversion groove 6 where it is located gradually decreases from top to bottom. The liquid near the top inside the diversion groove 6 is collected layer by layer through the cooperation of the collection pipe 9 and the collection opening 10.

[0027] Further, the collection cylinder 13 is made of a transparent material, which is convenient for observing the amount of liquid collected inside the collection cylinder 13.

[0028] In use, the raw materials to be subjected to flotation separation are added into the interior of the feeding cylinder 2. After the raw materials enter the interior of the feeding cylinder 2, they flow into the interior of the diversion trough 6 through the bottom opening 5 at the bottom of the feeding cylinder 2 and flow downward along the diversion trough 6. The raw materials flow along a spiral trajectory in the diversion trough 6. During the flowing process, stratification occurs due to different specific gravities inside. At the same time, the spiral trajectory flow will cause the liquid to generate centrifugal force. Under the action of the centrifugal force, the liquid approaches the inner wall of the outer-side diversion trough 6. Due to the specific gravity difference between the main component and the secondary salt, most of the secondary salt particles settle to the bottom position of the diversion trough 6 for flowing due to their large specific gravity, and a small amount of the main component particles flow along with the upper-side flotation solvent alcohol. When the flotation solvent alcohol flows through the collecting pipe 9, the upper-side flotation solvent alcohol is blocked by the collecting pipe 9, so that the upper-side solvent enters the interior of the collecting pipe 9 through the collecting opening 10, and then flows through the collecting pipe 9, the connecting elbow 11, the conveying vertical pipe 12 and the connecting pipe head 14 into the interior of the collecting cylinder 13 for storage. As the flotation solvent alcohol continues to flow downward, the distance between the collecting pipe 9 and the bottom of the diversion trough 6 gradually becomes smaller, so as to gradually collect the upper-side flotation solvent alcohol and collect it into different collecting cylinders 13. The lower the collecting pipe 9 is, the more particle content there is in the collected flotation solvent alcohol. Finally, the secondary salt particles flowing along the bottom of the diversion trough 6 are not collected by the collecting pipe 9 and the collecting opening 10 due to their large specific gravity and flow to the bottom inner wall of the separation box 1, and are finally discharged outwards through the bottom discharge pipe 4. The flotation solvent is sorted according to the content of the internal components, so as to facilitate the subsequent re-purification work according to the different contents of the waste residue mainly composed of aluminum chloride and sodium chloride.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
