Description

Technical Field

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

[0002] In the process of industrial production, some light component liquid products need to be purified. Among them, distillation and concentration is a commonly used method. The product is evaporated into a gas phase and then condensed and collected to achieve the purification effect. Distillation is a thermodynamic separation process. It uses the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling component and then condense to separate the entire component. It is a unit operation process that combines evaporation and condensation. Compared with other separation methods, such as extraction, filtration and crystallization, it has the advantage of not requiring the use of solvents other than the system components, thereby ensuring that no new impurities are introduced.

[0003] When the existing distillation device processes different solutions, due to the long time it takes for the tank to heat up, the suspended matter in the solution will settle to the bottom of the tank and accumulate together, resulting in incomplete evaporation. In addition, during the process of steam rising and condensing, the gathered steam molecules will adhere to the top of the tank and drip only by gravity, which is not collected thoroughly and reduces the distillation efficiency. In view of this, the present application proposes a distillation device. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a distillation device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, the water outlet pipe is slidably connected to the sealing cover and the top plate, and the bottom of the water outlet pipe extends into the collecting bucket.

[0008] Preferably, the plurality of stirring rods are circumferentially arranged, and the lower ends of the plurality of stirring rods are in contact with the bottom inner wall of the tank body.

[0009] Preferably, the transmission device comprises a reciprocating screw, a screw nut is threadedly connected to the reciprocating screw, and an assembly block is sleeved on the screw nut.

[0011] Preferably, the diameter of the collecting hopper is smaller than the diameter of the top plate, and the upper surface of the collecting hopper is designed to be arc-shaped and corresponds to the lower end of the top plate.

[0012] The utility model has the following beneficial effects:

[0013] 1. Through the reciprocating screw, screw nut and assembly block, after the motor is started, the output shaft of the motor will eventually drive the support rod to move up and down, so that the upper collecting bucket moves back and forth, and the upper end of the collecting bucket contacts the top plate.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A distillation device comprises a tank body 1, a sealing cover 2 is installed on the top of the tank body 1, a feeding pipe 3 connected with the interior thereof is provided on the side wall of the tank body 1, a water outlet pipe 4 connected with the interior thereof is provided on the top of the tank body 1, the water outlet pipe 4 is slidably connected with the sealing cover 2 and the top plate 12, and the bottom of the water outlet pipe 4 extends into a collecting bucket 11. It should be noted that the bottom of the water outlet pipe 4 is fixedly installed in the collecting bucket 11 and a gap is maintained between the water outlet pipe 4 and the collecting bucket 11, so that the liquid in the collecting bucket 11 can be discharged outward in time through an external pressure pump.

[0022] A motor 5 is fixedly installed at the bottom of the tank body 1 through a bracket, and the output shaft seal of the motor 5 passes through the bottom of the tank body 1. A plurality of stirring rods 6 are fixedly connected to the output shaft of the motor 5. The plurality of stirring rods 6 are circumferentially arranged, and the lower ends of the plurality of stirring rods 6 are in contact with the bottom inner wall of the tank body 1. Furthermore, during the rotation of the stirring rod 6, the precipitated suspended matter can be floated again to avoid accumulation at the bottom of the tank body 1, so that the raw materials inside the tank body 1 are evenly heated, thereby improving the utilization rate of the raw materials.

[0023] The upper end of the output shaft of the motor 5 is connected with a transmission device, which includes a reciprocating screw 7, a screw nut 8 is threadedly connected to the reciprocating screw 7, and an assembly block 9 is sleeved on the screw nut 8. The bottom of the reciprocating screw 7 is fixedly connected to the output shaft of the motor 5 through a coupling, and the assembly block 9 is fixedly connected to the lower ends of multiple support rods 10. It should be noted that since the water outlet pipe 4 is eccentrically set relative to the collecting bucket 11, the rotation of the collecting bucket 11 will be restricted. Therefore, when the output shaft of the motor 5 drives the reciprocating screw 7 to rotate, the screw nut 8 will not rotate, and finally drives the upper collecting bucket 11 to move along the direction set by the reciprocating screw 7.

[0024] The transmission device is connected to a collecting bucket 11 through a plurality of support rods 10, and a top plate 12 is fixedly installed on the inner wall of the tank body 1 through a base. A plurality of guide plates 13 are arranged on the lower surface of the top plate 12, and a drainage groove 14 is provided at the bottom of the top plate 12. The diameter of the collecting bucket 11 is smaller than the diameter of the top plate 12, and the upper surface of the collecting bucket 11 is designed to be arc-shaped and corresponds to the lower end of the top plate 12. It should be noted that the evaporated liquid will condense on the lower surface of the top plate 12. Under the action of the guide plates 13 and the drainage grooves 14, the attached liquid will gather together and drip into the collecting bucket 11 below. Furthermore, when the collecting bucket 11 is in contact with the top plate 12, the liquid gathered on the lower surface of the top plate 12 will flow into the collecting bucket 11 along the arc surface, so that the liquid at the contact surface can be thoroughly collected, thereby improving the condensation performance of the top plate 12.

[0025] When the utility model is in use, the raw materials to be processed are added into the tank body 1 through the feeding pipe 3, the tank body 1 is heated, and the motor 5 is started to run. The output shaft of the motor 5 will drive the multiple stirring rods 6 to rotate. The lower ends of the multiple stirring rods 6 are kept in contact with the bottom inner wall of the tank body 1, which can stir the raw materials to avoid the raw materials from piling up and increase the escape rate of steam molecules. At the same time, the output shaft of the motor 5 will drive the reciprocating screw 7 to rotate synchronously, and finally the screw nut 8 sleeved on the reciprocating screw 7 will move along the direction set by the reciprocating screw 7. Under the fixation of the assembly block 9, the upper collecting bucket 11 is driven to move by the support rod 10, so that the upper end of the collecting bucket 11 is fitted with the top plate 12, and flows into the collecting bucket 11 along the corresponding arc surface, and the collection is more thorough. At the same time, the guide plate 13 makes the water droplets attached to the top plate 12 converge and drip into the collecting bucket 11 through the drainage groove 14, thereby improving the collection efficiency.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
