Description

Technical Field

[0001] The invention relates to the technical field of distillation devices, and in particular to a distillation device. Background Art

[0002] Naphthols, commonly known as Naphthols, are a type of component of ice dyes. They are coupled with diazonium salts of another type of component, chromophores, on fibers to form insoluble azo dyes, which are mostly made by condensing 2-hydroxy-3-naphthoic acid with aniline after acylation. In addition, there are derivatives of hydroxycarboxamides of carbazole and anthracene, such as Naphthols AS-LB and Naphthols AS-GR. A type of Naphthols can often be coupled with different chromophore diazonium salts to form different azo dyes with different hues and fastnesses.

[0003] The Chinese utility model patent with the authorization announcement number "CN219423740U" is specifically "a distillation device". The beneficial effect section of its specification states that "the top of the distillation tank is set to an open and inclined shape and covered with a mesh plate, and a waterproof breathable membrane is fixed on the mesh plate. When the steam passes through the waterproof breathable membrane and meets the condenser tube, it condenses into liquid and finally slides to the drain pipe and then flows into the recovery box. It has a large steam permeability area and high condensation efficiency."

[0004] The above-mentioned device arranges a waterproof breathable membrane at a fixed position in the inner cavity of the distillation tank, and utilizes the waterproof breathable membrane's water-proof and breathable properties to increase the breathable area and improve the condensation efficiency. However, it is found in actual use that the hot air that passes through the waterproof breathable membrane and contacts the condenser tube will be pre-cooled to form water droplets that fall on the waterproof breathable membrane, which can easily cause damage to the waterproof breathable membrane. In addition, although the waterproof breathable membrane can allow high-temperature hot air to pass through, the high-temperature steam will still encounter obstacles when passing through the waterproof breathable membrane, thereby reducing the ventilation speed, and further affecting the contact frequency between the high-temperature steam and the condenser tube, ultimately reducing the condensation efficiency. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a distillation device, which can effectively solve the problem of low condensation efficiency in the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The present invention provides a distillation device, comprising a distillation tank, wherein a baffle is obliquely installed at the top of the inner cavity of the distillation tank, a condenser is arranged above the baffle, and an outer wall of the distillation tank is provided with a liquid discharge port which is connected with the inner cavity of the distillation tank and opposite to the baffle.

[0008] Furthermore, a connected feed pipe is installed on the outer side wall of the distillation tank, a feed hopper is installed at one end of the feed pipe away from the distillation tank, and a first valve is installed at the connection between the feed hopper and the feed pipe.

[0009] Furthermore, a second valve is installed at the output port of the discharge port, and the output end and the output end of the condenser are respectively installed with a cold water pipe and a hot water pipe fixedly installed on both sides of the distillation tank.

[0010] Furthermore, the first enhancement component also includes a motor fixedly mounted on the top of the distillation tank, the output end of the motor is equipped with a rotating rod extending into the distillation tank, and the stirring paddle and the fan blades are fixedly sleeved on the outer rod wall of the rotating rod.

[0011] Furthermore, the filter assembly also includes an air intake seat embedded between the outer wall of the distillation tank and the inner wall of the distillation tank, the filter cartridge is rotatably installed in the air intake seat, and a connecting ring connected to the exhaust pipe is provided on the top of the filter cartridge.

[0012] Furthermore, a rotating tube is fixedly connected to the top center position of the filter cylinder, the connecting ring is wrapped around the outer tube wall of the rotating tube and is connected to the inner cavity of the filter cylinder, a first transmission wheel is installed on the top of the rotating tube, a second transmission wheel is fixedly wrapped around the outer rod wall of the rotating rod, and a transmission belt is wrapped around the first transmission wheel and the second transmission wheel.

[0013] Furthermore, a reflux assembly is installed on the baffle, and the reflux assembly includes a reflux pipe running through the center of both sides of the baffle, and a one-way exhaust valve is installed at the bottom end of the reflux pipe.

[0014] Furthermore, a truncated cone-shaped waterproof cap is installed at the top of the return pipe, and a gap is provided between the waterproof cap and the top of the return pipe.

[0015] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0016] First, a first synergistic component is arranged in the distillation tank. The first synergistic component includes a plurality of rotating stirring paddles and fan blades. The rotating stirring paddles can accelerate the flow of the reaction solution in the distillation tank, thereby increasing the liquid evaporation efficiency. The rotating fan blades can accelerate the high-temperature evaporation air below the baffle to the top of the baffle, thereby increasing the contact frequency between the high-temperature air and the condensation tube, and preliminarily improving the condensation efficiency.

[0017] Secondly, a fan is installed on the outer wall of the distillation tank. The fan is started to add air filtered by the filter cartridge into the reaction solution in the distillation tank through the exhaust pipe, thereby further increasing the flow rate of the reaction solution.

[0029] The present invention will be further described below in conjunction with the embodiments.

[0030] Example 1

Air is blown by the fan 3, and the air filtered by the filter cartridge 32 is discharged from the exhaust pipe 38, forming bubbles in the reaction solution, accelerating the flow of the reaction solution, and increasing the inner cavity pressure of the distillation tank 1, thereby improving the reaction efficiency. Under the premise that there is no reaction solution in the distillation tank 1, the fan 3 is started in reverse regularly to extract dust remaining in the inner cavity of the air inlet seat 31, ensuring that the filter cartridge 32 can maintain a good filtering effect for a long time without the need for disassembly and cleaning.

[0032] Example 2

[0033] Reference Figure 1-5 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: a connected feed pipe 11 is installed on the outer side wall of the distillation tank 1, and a feed hopper 12 is installed at the end of the feed pipe 11 away from the distillation tank 1 for convenient feeding, a first valve 13 is installed at the connection between the feed hopper 12 and the feed pipe 11 for convenient closing of the feed pipe 11, a second valve 15 is installed at the output port of the drain port 14 for convenient closing of the drain port 14, and the output end and output end of the condenser 16 are respectively installed with a cold water pipe 17 and a hot water pipe 18 fixedly installed on both sides of the distillation tank 1 to form a cooling water circulation system, and the first synergistic component also includes a The motor 2 has a rotating rod 21 extending into the distillation tank 1 installed at its output end, and the stirring paddle 22 and the fan blade 23 are fixedly mounted on the outer rod wall of the rotating rod 21. The baffle 4 has a reflux assembly installed, and the reflux assembly includes a reflux pipe 41 passing through the centers of both sides of the baffle 4, a one-way exhaust valve 42 is installed at the bottom end of the reflux pipe 41, and a truncated cone-shaped waterproof cap 43 is installed at the top end of the reflux pipe 41 to prevent falling liquid droplets from entering the reflux pipe 41. A gap is provided between the waterproof cap 43 and the top end of the reflux pipe 41 to facilitate excess gas to enter the reflux pipe 41 from the gap and reflux to the bottom of the baffle 4, thereby increasing the gas circulation speed in the distillation tank 1.

[0034] The remaining structures are the same as those of Example 1.

[0035] Example 3

[0036] Reference Figure 6-8 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the filter assembly also includes an air inlet seat 31 embedded and installed between the outer wall of the distillation tank 1 and the inner wall of the distillation tank 1, the air inlet seat 31 is connected to the output end of the fan 3, the filter cartridge 32 is rotatably installed in the air inlet seat 31, the top of the filter cartridge 32 is provided with a connecting ring 33 connected to the exhaust pipe 38, the top center position of the filter cartridge 32 is fixedly connected to a rotating tube 34, the connecting ring 33 surrounds the outer tube wall of the rotating tube 34, and the outer tube wall of the rotating tube 34 penetrates the inner tube cavity to open a plurality of The inner wall of the connecting ring 33 is connected to the air hole, so no matter how the rotating tube 34 rotates to any angle, the connecting ring 33 is still connected to the rotating tube 34, and the inner cavity of the filter cylinder 32 is directly connected to the inner cavity of the rotating tube 34. Therefore, the connecting ring 33 is directly connected to the inner cavity of the filter cylinder 32, and a first transmission wheel 35 is installed on the top of the rotating tube 34. The outer rod wall of the rotating rod 21 is fixedly mounted with a second transmission wheel 36. A transmission belt 37 is mounted around the first transmission wheel 35 and the second transmission wheel 36. Two small holes are provided on the inner wall of the distillation tank 1 for the transmission belt 37 to extend and retract through.

[0037] The remaining structure is the same as that of Example 2.

[0038] In the first step, the second valve 15 is closed, the first valve 13 is opened, the reaction solution and the reaction material are added into the distillation tank 1 through the feed hopper 12, and then the first valve 13 is closed, so that the interior of the distillation tank 1 is relatively closed;

[0039] The second step is to place the distillation tank 1 in the adding device to increase the tank body temperature, thereby promoting the evaporation of the solution inside the distillation tank 1. At the same time, the motor 2 is started to drive the rotating rod 21 to rotate, thereby driving a plurality of stirring paddles 22 and fan blades 23 to rotate synchronously. Since the stirring paddles 22 are arranged at the bottom and in direct contact with the reaction solution, the rotating stirring paddles 22 can accelerate the flow of the reaction solution, thereby improving the evaporation efficiency. Since the fan blades 23 are arranged at the top and opposite to the bottom position of the baffle 4, the hot air flow formed by the evaporation of the reaction solution can be quickly sent into the inner cavity of the distillation tank 1 above the baffle 4;

[0040] The third step is to start the fan 3 and inject air into the air inlet seat 31. The air passes through the filter holes on the surface of the filter cartridge 32 and enters the inner cylinder cavity of the filter cartridge 32. Dust and impurities with larger particles are intercepted in the inner cavity of the air inlet seat 31 outside the filter cartridge 32, and then pass through the rotating tube 34 and the connecting ring 33, and finally enter the distillation tank 1 through the exhaust pipe 38. Under the premise that the internal volume of the distillation tank 1 remains unchanged, the internal pressure of the distillation tank 1 is increased, thereby improving the reaction efficiency. The rotation of the rotating rod 21 also synchronously drives the second transmission wheel 36 to rotate, and through the transmission of the transmission belt 37, drives the first transmission wheel 35 to rotate, and then drives the rotating tube 34 to rotate, and also drives the filter cartridge 32 to rotate. Under the premise that the normal filtering and circulation of air is no longer affected, the filter holes on the surface of the filter cartridge 32 are not easily blocked, ensuring that the filter cartridge 32 can effectively filter the air for a long time.

[0041] In the fourth step, low-temperature cooling water is injected into the condenser tube 16 through the cold water pipe 17. After contacting with the high-temperature hot air, the high-temperature hot air will be pre-cooled and condensed to form liquid drops on the baffle 4, and gather near the second valve 15 along the inclined surface of the baffle 4. The high-temperature hot water formed by the condenser tube 16 after heating will be discharged from the hot water pipe 18, forming a cooling circulation water system to ensure long-term condensation effect;

[0042] In the fifth step, when the pressure in the distillation tank 1 above the baffle 4 increases, it will flow back to the bottom of the baffle 4 through the reflux pipe 41, increasing the gas circulation speed in the distillation tank 1, thereby increasing the contact frequency with the condenser 16 and improving the condensation efficiency.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
