Technical Field

[0001] The present application relates to the technical field of salt separation devices, and in particular to a glycerol salt separation device. Background Art

[0002] Glycerin distillation is a chemical process designed to separate and purify glycerin by heating it to its boiling point in a still and then condensing the vapors.

[0003] In the crude distillation process of glycerol, the common method is to introduce the raw materials into the distillation kettle and evaporate them by heating. In order to remove the liquid and impurities remaining in the distillation kettle, it is usually necessary to stop the device after each distillation cycle, drain the liquid and remove the salt and other residues deposited in the kettle by manual cleaning. This method is not only time-consuming and labor-intensive, but also the manual cleaning process may cause damage to the equipment, increasing maintenance costs.

[0004] However, in the existing glycerin distillation process, salt is easily deposited on the inner wall and bottom of the still, causing increased corrosion and wear of the equipment. This not only affects the service life of the still, but also may reduce the production efficiency and quality of glycerin. Therefore, how to reduce the salt deposited in the still during the distillation process, protect the equipment and extend its service life has become a key issue that needs to be solved urgently. Summary of the invention

[0007] By adopting the above technical solution, the distillation chamber and the heating part in the kettle body heat and distill the glycerin, and the rotating shaft and the stirring blade are used to stir the glycerin in the distillation chamber to ensure that the glycerin is heated evenly. The bottom of the stirring blade is in sliding contact with the bottom of the distillation chamber, which can effectively push the bottom sediment. Through the design of the collection box and the connecting hole, the separated salt particles can be collected in the collection box, reducing the number of salt particles deposited in the distillation chamber during the distillation process. The design of the hinged shaft and the partition net can automatically flip the partition net when the stirring blade moves to the vicinity of the connecting hole, control the inflow and collection of salt particles, and at the same time block the connecting hole through the partition net, reducing the possibility that the salt particles in the collection tank will be disturbed by the glycerol and drive the distillation chamber when the next stirring blade moves to the vicinity of the connecting hole.

[0008] Optionally, the control assembly includes a control coil spring, a control rope and a control block; The control coil spring is wound around the outer peripheral side of the hinge shaft, one end of the control coil spring is clamped to the hinge shaft, and the other end is clamped to the kettle body; When the control coil spring is released, the hinge shaft is driven to rotate, driving the partition net to flip to a position to block the opening of the communication hole; The control block is slidably connected to the kettle body, and the control block is located on the peripheral wall of the distillation chamber; The control rope is slidably inserted into the kettle body, the control rope is wound around the outer peripheral side of the hinge shaft, one end of the control rope is connected to the hinge shaft, and the other end is connected to the control block; When the stirring blade slides close to the opening of the communicating hole, the stirring blade pushes the control block to slide, and at this time, the control rope pulls the hinge shaft to rotate, so that the partition net flips into the collecting tank; The kettle body is formed with receiving grooves corresponding to the control blocks one by one, and the kettle body is formed with a guiding surface for guiding the control blocks to slide into and out of the receiving grooves; When the stirring blade pushes the control block to slide into the containing groove, the stirring blade passes through the control block, and at this time the control coil spring is released.

[0015] By adopting the above technical solution, the driving assembly realizes precise control of the blocking plate through the cooperation of the driving rope, the driving block and the driving spring. When the rotating blade pushes the driving block to slide, the driving rope pulls the blocking plate to open the salt collecting tank; when the rotating blade passes the middle position of the salt collecting tank, the driving spring drives the blocking plate to block the salt collecting tank.

A liquid inlet pipe 13, a liquid outlet pipe 14 and a condenser 15 are fixedly installed on the kettle body 1, and the liquid inlet pipe 13, the liquid outlet pipe 14 and the condenser 15 are respectively connected to the distillation chamber 111. Among them, the liquid outlet pipe 14 is located near the bottom of the kettle body 11, and is used to discharge the residue in the kettle body 1; the liquid inlet pipe 13 and the condenser 15 are respectively located at the top of the kettle body 1, and the condenser 15 is connected to an external condenser. A heating part 16 is arranged outside the kettle body 1, and the heating part 16 is a heating pipe, which is arranged around the kettle body 1 and is used to heat the glycerol in the distillation chamber 111. When in use, the glycerin to be distilled is introduced into the distillation chamber 111 through the liquid inlet pipe 13, and then the glycerin is heated by the heating part 16. The steam generated when the glycerin is heated is discharged through the condenser 15, and then the steam enters the condenser for condensation.

The stirring blade 21 is installed and fixed on the outer peripheral side of the rotating shaft 2, and there are multiple stirring blades 21 and they are evenly spaced along the circumferential direction. When the rotating shaft 2 rotates, it drives the stirring blade 21 to rotate, and at this time, the bottom of the stirring blade 21 is in sliding contact with the bottom of the distillation chamber 111. The kettle body 1 is provided with a driving member, and the driving member is a driving motor 17 (the driving motor 17 is Figure 2 ), the driving motor 17 is fixed on the top of the kettle body 1, the output shaft of the driving motor 17 is rotatably connected to the kettle body 1, the end of the output shaft of the driving motor 17 is fixedly connected with a clamping block, and a clamping groove is formed on the top of the rotating shaft 2, and the clamping block is clamped into the clamping groove, so that the output shaft of the driving motor 17 and the rotating shaft 2 are linked. When the driving motor 17 is started, it drives the rotating shaft 2 to rotate, so that the stirring blade 21 stirs the glycerin in the distillation chamber 111, so that the glycerin can flow, and the uniformity of the glycerin heating is improved.

[0032] See also Figure 3 and Figure 5 The collecting box 3 is fixed to the bottom of the kettle body 1, and the collecting box 3 is a cubic structure. The collecting box 3 is formed with a collecting groove 31. The collecting boxes 3 correspond to the stirring blades 21 one by one, and the collecting boxes 3 are evenly spaced along the circumferential direction. A communicating hole 18 is formed at the bottom of the kettle body 1, and the communicating hole 18 is connected to the distillation chamber 111 and the collecting groove 31.

[0033] See also Figure 3 and Figure 4 The hinge shaft 4 is rotatably connected to the kettle body 1, and the hinge shaft 4 is located at the top opening of the communicating hole 18. There are multiple hinge shafts 4 and they correspond to the communicating holes 18 one by one. A partition net 41 is fixedly connected to the hinge shaft 4 to block the opening of the communicating hole 18. The mesh of the partition net 41 is fine, which can allow the glycerin in the collecting tank 31 to pass through while limiting the passage of salt particles.

[0034] See also Figure 3 and Figure 5 The glycerol salt separation device also includes a control component, which is arranged on the kettle body 1. When the stirring blade 21 moves to a position adjacent to the opening of the connecting hole 18, the control component controls the hinge shaft 4 to rotate, so that the partition net 41 flips into the collecting tank 31; when the stirring blade 21 moves to a position close to the middle of the connecting hole 18, the control component controls the hinge shaft 4 to rotate, so that the partition net 41 flips to a horizontal state, thereby blocking the opening of the connecting hole 18.

[0035] See also Figure 4 and Figure 6 The control assembly includes a control coil spring 51, a control rope 52 and a control block 5. The control coil spring 51 is wound around the outer peripheral side of the hinge shaft 4 and is located in the kettle body 11. One end of the control coil spring 51 is clamped and fixed on the outer peripheral side wall of the hinge shaft 4, and the other end is clamped on the kettle body 1. When the control coil spring 51 is released, the hinge shaft 4 is driven to rotate, driving the partition net 41 to flip to a horizontal state, and the position of the opening of the communication hole 18 is blocked.

[0037] When the stirring blade 21 slides close to the opening of the connecting hole 18, the stirring blade 21 pushes the control block 5 to slide. At this time, the control rope 52 pulls the hinge shaft 4 to rotate, so that the partition net 41 flips into the control groove. The kettle body 11 is formed with a receiving groove 19 corresponding to the control block 5. The receiving groove 19 is connected to the control groove, and the kettle body 11 forms a guide surface 191, and the control block 5 slides on the guide surface 191.

[0038] The control block 5 is provided with a control surface which is inclined and is located in the distillation chamber 111; when the control block 5 slides to the guide surface 191, the stirring blade 21 slides on the control surface; then the control block 5 slides on the guide surface 191 and slides toward the receiving tank 19, until the control block 5 slides into the receiving tank 19, the stirring blade 21 separates from the control block 5, at which time the hinge shaft 4 drives the partition net 41 to flip into the collecting tank 31, and during the stirring movement of the stirring blade 21, the salt particles deposited on the bottom of the distillation chamber 111 are pushed onto the partition net 41, and then the salt particles slide along the partition net 41 into the collecting tank 31, thereby collecting the salt particles. Then, as the stirring blade 21 continues to slide, the stirring blade 21 passes through the control block 5, and then the control coil spring 51 (the control coil spring 51 is in Figure 4 The elasticity of the connecting member 12 (marked in the middle) is released, driving the hinge shaft 4 to rotate, so that the control rope 52 pulls the control block 5 from the receiving groove 19 to slide into the control groove. At this time, the partition net 41 flips to a horizontal state to block the opening of the connecting hole 18, thereby reducing the possibility that the salt particles in the collecting tank 31 are brought into the distillation chamber 111 by the disturbed glycerin when the next stirring blade 21 moves close to the opening of the connecting hole 18.

[0039] See also Figure 7 and Figure 8 , a mounting groove 211 is formed on the end surface of the side where the stirring blade 21 is impacted, and when the stirring blade 21 moves, the glycerol impacts the stirring blade 21 and enters the mounting groove 211.

[0048] See also Figure 8 and Fig. 9 The driving block 82 is slidably connected to the side wall of the installation groove 211. When the rotating blade 61 flips into the installation groove 211, the rotating blade 61 abuts against the driving block 82 and pushes the driving block 82 to slide. The driving rope 81 is slidably arranged in the stirring blade 21. One end of the driving rope 81 is connected and fixed to the driving block 82, and the other end is connected and fixed to the blocking plate 215 away from the salt collecting tank 212 (the salt collecting tank 212 is at Figure 5 (marked in the middle) primary groove wall.

[0049] The rotating blade 61 rotates close to the salt collecting tank 212 (the salt collecting tank 212 is Figure 5During the process of rotating blade 61 first abutting driving block 82, and then when rotating blade 61 continues to rotate, driving block 82 is pushed to slide, at this time driving rope 81 pulls blocking plate 215 to slide into salt collecting tank 212 in chute 216, and driving spring 83 enters a compressed state. When rotating blade 61 moves through the middle position of salt collecting tank 212, rotating blade 61 slides on driving block 82, at this time rotating blade 61 is away from driving block 82, and then driving spring 83 is elastically released, driving blocking plate 215 to slide out of chute 216, and blocking salt collecting tank 212, reducing the possibility that salt particles in mounting groove 211 are brought out of salt collecting tank 212 by disturbed glycerol when the next rotating blade 61 moves to near the opening of connecting hole 18.

[0050] The implementation principle of a glycerol salt separation device in the embodiment of the present application is: During the glycerol distillation process, the salt in the glycerol gathers to form salt particles, and the rotating shaft 2 drives the stirring blade 21 to rotate during the glycerol distillation, thereby improving the uniformity of heat distribution in the glycerol. When the stirring blade 21 moves, the salt particles deposited at the bottom of the distillation chamber 111 are pushed into the collecting tank 31. At the same time, during the movement of the stirring blade 21, the connecting shaft 6 drives the rotating blade 61 to rotate, so that the rotating blade 61 brings the salt particles floating in the glycerol into the installation tank 211, and then pushes the salt particles into the salt collecting tank 212, thereby reducing the number of salt particles floating in the glycerol and improving the evaporation rate of the glycerol.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
