Description

Technical Field

[0001] The utility model relates to the technical field of extraction, in particular to a dioxolane extraction and purification device. Background Art

[0002] Dioxolane is an excellent organic solvent with a wide range of uses. It is mainly used as a solvent for oils and fats, an extractant, an electrolytic solvent for lithium batteries, a chlorine-based solvent stabilizer, a pharmaceutical intermediate, and a raw material for copolymer formaldehyde. It can also be used as a silk finishing agent and a raw material for sealing adhesives. A necessary step in the production process of dioxolane is extraction and purification.

[0003] The extraction and purification device in the prior art has a simple structure, and the extraction process basically relies on the self-reaction and sedimentation stratification of the material. The reaction process is long and wastes a lot of time. To this end, Chinese patent CN213853210U proposes a 4-chloro-2-aminobiphenyl extraction device, which improves the extraction efficiency by adding a stirring structure in the extraction tank; but this design has the following defects during use: on the one hand, after the extraction is completed, a large amount of raw liquid will adhere to the stirring structure, making the stirring structure difficult to clean; on the other hand, after the extraction is completed, this structure setting is not convenient for subsequent cleaning operations in the extraction tank. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a dioxolane extraction and purification device.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A dioxolane extraction and purification device comprises a mounting frame, on which a first rotating tube and a second rotating tube are horizontally rotatably arranged, the first rotating tube is connected to a driving motor arranged on the mounting frame, and an extraction tank is arranged between the first rotating tube and the second rotating tube; a feed pipe and a discharge pipe are arranged on the extraction tank, a feed valve is installed on the feed pipe, and a discharge valve is installed on the discharge pipe; a spray pipe with a circular ring structure is arranged in the extraction tank, a plurality of spray holes are arranged on the spray pipe, and the spray pipe is connected to a liquid guide component, which passes through the extraction tank and extends to the outside of the second rotating tube.

[0007] Furthermore, the liquid guiding assembly includes a branch pipe, a rotating joint, a liquid guiding tube and a quick joint; one end of the branch pipe is connected to the spray pipe, and the other end passes through the extraction tank and is connected to the liquid guiding tube through the rotating joint; one end of the liquid guiding tube extends to the outside of the second rotating tube and is installed with a quick joint, which can be conveniently connected to the external water inlet pipe through the quick joint.

[0008] Furthermore, a pressure balancing valve is installed on the extraction tank.

[0009] Furthermore, the spray holes are continuously arranged in the circumferential direction of the spray pipe body so that the sprayed water is dispersed all around, thereby improving the cleaning effect.

[0010] Furthermore, the extraction tank is provided with a transparent window along its height direction to facilitate liquid separation operation.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model utilizes the rotation of the extraction tank itself to replace the traditional stirring structure, thereby reducing the adhesion of the original liquid in the extraction tank; at the same time, through the arrangement of the spray pipe and the liquid guide component, the cleaning effect on the inside of the extraction tank is greatly improved, and the cleaning efficiency is high.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0017] See attached Figure 1As shown, a dioxolane extraction and purification device comprises a mounting frame 1, on which a first rotating tube 11 and a second rotating tube 12 are horizontally rotatably arranged, the first rotating tube 11 is connected to a driving motor 2 arranged on the mounting frame 1, and an extraction tank 3 is arranged between the first rotating tube 11 and the second rotating tube 12 so that the driving motor 2 operates to make the extraction tank 3 perform a vertical rotation movement; a feed pipe 31 and a discharge pipe 33 are arranged on the extraction tank 3, a feed valve 32 is installed on the feed pipe 31, and a discharge valve 34 is installed on the discharge pipe 33; a spray pipe 4 in a circular ring structure is arranged in the extraction tank 3, and a plurality of spray holes 41 are arranged on the spray pipe 4, and a liquid guide component is connected to the spray pipe 4, which passes through the extraction tank 3 and extends to the outside of the second rotating tube 12.

[0018] Specifically, the liquid guiding assembly includes a branch pipe 42, a rotating joint 43, a liquid guiding pipe 44 and a quick connector 45; one end of the branch pipe 42 is connected to the spray pipe 4, and the other end passes through the extraction tank 3 and is connected to the liquid guiding pipe 44 through the rotating joint 43. One end of the liquid guiding pipe 44 extends to the outside of the second rotating tube 12 and is installed with a quick connector 45, which can be conveniently connected to the external water inlet pipe through the quick connector 45.

[0019] During the specific implementation of the device, the dioxolane extraction liquid and the extraction reagent are injected into the extraction tank 3 through the feed pipe 31, and then the feed valve 32 is closed, and then the drive motor 2 is started. Under the action of the drive motor 2, the extraction tank 3 begins to rotate vertically to allow the dioxolane extraction liquid and the extraction reagent therein to fully react until the reaction is completed, and then the extraction tank 3 is stopped. At this time, stratification occurs in the extraction tank 3. Finally, the drain valve is opened to perform the liquid separation operation; when it is necessary to clean the extraction tank 3, the drive motor 2 is started to make the extraction tank 3 start to rotate vertically. At the same time, the external water inlet pipe is connected to the quick connector 45. At this time, the external water body is pumped into the spray pipe 4 and sprayed toward the inner wall of the extraction tank 3 through the spray hole 41. The inner wall of the extraction tank 3 is fully in contact with the water body and is thoroughly cleaned.

[0020] To further refine the above scheme, the dioxolane extract will produce gas during the reaction with the extraction reagent, which will cause the pressure in the extraction tank 3 to increase. In order to keep the extraction tank 3 in a balanced state with the external pressure, a pressure balance valve 35 is installed on the extraction tank 3.

[0021] The above scheme is further refined. To improve the spraying effect of the spray pipe 4 and make the water sprayed from the spray pipe 4 cover a larger area, the spray holes 41 are continuously arranged in the circumferential direction of the spray pipe 4 so that the sprayed water is dispersed around.

[0022] In order to facilitate the user to observe the level of the stratified liquid in the extraction tank 3 and facilitate the subsequent liquid separation operation, refer to the attached Figure 2 As shown, the extraction tank 3 is provided with a transparent window 36 along its height direction.

[0023] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the protection required by the utility model. The scope of protection required by the utility model is defined by the attached claims and their equivalents.
