Description

Technical Field

[0001] The present application relates to the technical field of distillation separation equipment, and in particular to a glass-lined distillation equipment. Background Art

[0002] Glass enamel, also known as porcelain enamel, is a traditional surface treatment technology for inorganic non-metallic materials. It is mainly achieved by coating one or more layers of glass glaze on the surface of metal, glass, ceramic and other materials, and then sintering them at high temperature to make the glaze and the substrate closely bonded to form a composite material with specific properties.

[0003] Glass-lined distillation equipment is mainly used to separate and purify compounds. Short-range molecular distillation is a special liquid-liquid separation technology that achieves separation by the difference in the mean free path of molecular motion of different substances. When the glass-lined short-range molecular distiller is in use, light molecules are condensed and discharged through the condensation plate, while heavy molecules are discharged along the mixed liquid.

[0004] Referring to the Chinese patent document with announcement number CN114748880B and titled "A film scraping device for a molecular distillation device and a film scraping thickness adjustment method", the film scraping device includes a transmission shaft, a cross bracket, a scraper bracket and a film scraping thickness adjustment device, the transmission shaft is fixedly connected to the cross bracket in the vertical direction along the center point of the cross bracket, the four ends of the cross bracket are fixedly connected to the scraper component through a connecting rod in the vertical direction, and each end of the cross bracket is connected to the scraper bracket through a groove and a spring hole along the horizontal axis. When the film scraping device is used, the transmission shaft drives the cross bracket to rotate while the scraper bracket rotates synchronously, the scraper scrapes the liquid on the cylinder wall, and the liquid is spread on the cylinder wall, so that the molecules in the liquid are easier to separate, and the film scraping thickness adjustment device can be used to complete the film scraping thickness adjustment.

[0005] Referring to the above technical solution, the scraper spreads the liquid flat on the inner wall of the cylinder. At the moment the scraper contacts the liquid, the liquid quickly diffuses to the surroundings driven by the scraper. Part of the liquid diffused to the outlet may be directly squeezed out when the light molecules have not been completely decomposed, so that the mixed liquid still contains light molecules. Summary of the invention

[0006] In view of this, the present application provides a glass-lined distillation device, which is mainly used to solve the problem of low light molecule separation efficiency during distillation of glass-lined liquid.

[0007] In order to solve the above-mentioned technical problems, the present application provides a glass-lined distillation equipment, including a distillation cylinder, a condenser, a rotating bracket, a liquid spraying assembly and a first driving member for driving the rotating bracket to rotate, the rotating rod of the first driving member passes through the top of the distillation cylinder, the rotating bracket is vertically arranged, and a plurality of telescopic rods that can move horizontally are installed on the rotating bracket through elastic members, the telescopic rods are rotatably connected to a vertically arranged film-making roller, and abutment rollers for abutting against the inner wall of the distillation cylinder are installed at both ends of the film-making roller, and a spiral groove for driving the liquid to move upward is opened on the film-making roller, and the spiral groove is opened spirally upward around the film-making roller.

[0008] By adopting the above technical scheme, the mixed liquid can be sprayed on the inner wall of the distillation cylinder through the spray assembly, the elastic part can drive the telescopic rod to extend and retract, so that the abutment roller is always in abutment with the inner wall of the distillation cylinder, and the film roller has a certain distance from the inner wall of the distillation cylinder, so that the mixed liquid can flow downward along the inner wall of the distillation cylinder. When the spiral groove on the abutment roller contacts the mixed liquid, the spiral groove can drive the mixed liquid to move upward, prolonging the time that the mixed liquid stays on the inner wall of the distillation cylinder, preventing the mixed liquid from flowing quickly to the outlet, ensuring that the light molecules in the mixed liquid are fully distilled and separated, and the light molecules flow out along the surface of the condenser under the condensation action of the condenser.

[0009] Optionally, the liquid spray assembly includes a liquid inlet main pipe, a plurality of liquid inlet branch pipes are connected to the liquid inlet main pipe, and the liquid inlet branch pipes are connected to spray nozzles.

[0010] By adopting the above technical solution, the mixed liquid can enter the liquid inlet branch pipe through the liquid inlet main pipe, and the mixed liquid can be evenly sprayed on the inner wall of the upper part of the distillation cylinder through the nozzle.

[0011] Optionally, a spray assembly is installed on the rotating bracket, and the spray assembly includes an articulated base fixedly mounted on the rotating bracket, a rotating wheel is hingedly arranged on the articulated base, a sleeve shaft is connected to the rotating rod, a tooth plate is arranged in a ring array on the sleeve shaft, the rotating wheel is meshed with the tooth plate, the spray head is arranged on the rotating wheel, and a second driving member is arranged on the sleeve shaft for driving the sleeve shaft to move up and down along the rotating rod.

[0012] By adopting the above technical solution, the second driving member can drive the sleeve shaft to move up and down along the rotating rod, and then drive the tooth plate to move up and down. When the wheel and the tooth plate are engaged, the teeth on the tooth plate drive the wheel to rotate, and then the water spray angle of the nozzle can be adjusted, so that the inner wall of the distillation cylinder can be better cleaned.

[0013] Optionally, a protective cover shell for preventing liquid from being thrown out is installed on the telescopic rod, and the protective cover shell is arranged around the side of the film-distributing roller away from the inner wall of the distillation cylinder.

[0014] By adopting the above technical solution, when the film roller rolls on the mixed liquid, the rotation of the film roller may drive the mixed liquid to be thrown outward. The protective cover can prevent the mixed liquid from being thrown onto the surface of the condenser, prevent the light molecules separated by distillation from containing the mixed liquid, and improve the separation quality of the light molecules of the mixed liquid.

[0015] Optionally, a scraper for spreading the liquid is connected to the protective cover.

[0016] By adopting the above technical solution, the scraper can scrape the mixed liquid on the inner wall flat, and when the mixed liquid is heated, the heating surface of the mixed liquid is guaranteed. At the same time, the mixed liquid is spread flat on the inner wall of the distillation cylinder, which can prevent the mixed liquid from accumulating and ensure the speed of heating distillation.

The top plate is arranged as a circular structure, the top plate and the auxiliary ring are arranged coaxially, and three telescopic sleeves are arranged in a circular array on the top plate and the auxiliary ring, and a support rod is installed between the upper and lower corresponding telescopic sleeves.

[0018] By adopting the above technical solution, three telescopic sleeves are provided on the top plate and the auxiliary ring. The three telescopic sleeves are grouped in two and correspond to each other one by one. The corresponding three film-making rollers can increase the contact time between the film-making rollers and the mixed liquid, and further extend the time that the mixed liquid stays on the inner wall of the distillation cylinder.

[0019] Optionally, the distillation cylinder is provided with a mixture outflow tube and a distillation molecule outflow tube.

[0020] By adopting the above technical solution, the light molecules of the mixed liquid after distillation flow out from the distillation molecule outflow pipe along the surface of the distiller, and the remaining mixture flows out directly along the mixture outflow pipe on the inner wall of the distillation cylinder.

[0021] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0022] 1. When the roller contacts the mixed liquid on the inner wall of the distillation cylinder, the spirally rotating groove on the roller can drive the mixed liquid to move upward a certain distance, which can increase the time the mixed liquid stays on the inner wall of the distillation cylinder. By setting multiple rollers, the time the mixed liquid stays on the inner wall of the distillation cylinder can be further extended, so that the light molecules inside the mixed liquid can be fully heated and distilled, and separated from the mixed liquid, thereby improving the quality of distillation separation.

[0023] 2. When cleaning the inner wall of the distillation cylinder, the quality of flushing can be improved by changing the spraying angle of the nozzle so that the nozzle flushes the inner wall of the distillation cylinder and the rotating bracket. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The present embodiment provides a glass-lined distillation device, comprising a distillation cylinder 1, a condenser 2, a rotating bracket 3, a liquid spraying assembly 5 and a spraying assembly 6. The condenser 2 and the rotating bracket 3 are installed inside the distillation cylinder 1. The condenser 2 is cylindrical in shape and is coaxially arranged with the distillation cylinder 1. The liquid spraying assembly 5 and the spraying assembly 6 are installed on the rotating bracket 3. The liquid spraying assembly 5 is used to spray the mixed liquid onto the inner wall of the distillation cylinder 1. When the liquid spraying assembly 5 and the spraying assembly 6 are used in combination, the inner wall and internal parts of the distillation cylinder 1 can be sprayed.

[0036] Reference Figure 1 and Figure 2 , the distillation cylinder 1 is equipped with a vertical rod 13, a support plate 14, a first driving member 4, a mixture outflow pipe 11, a through-tube 15 and a distillation molecule outflow pipe 12. A plurality of vertical rods 13 are fixedly installed on the top of the distillation cylinder 1, and the vertical rods 13 are distributed in a circular array around the central axis of the distillation cylinder 1. The upwardly extending end of the vertical rod 13 is provided with a support plate 14, and the first driving member 4 is fixedly installed on the support plate 14. The first driving member 4 is used to drive the rotating bracket 3 to rotate. The rotating rod 41 on the output shaft of the first driving member 4 penetrates the top of the distillation cylinder 1 and is fixedly connected to the top of the rotating bracket 3. The distillation cylinder 1 is equipped with a mixture outflow pipe 11, and the mixture distilled on the inner wall of the distillation cylinder 1 flows out from the mixture outflow pipe 11. The bottom of the condenser 2 is provided with a through-tube 15, and the through-tube 15 penetrates the bottom of the distillation cylinder 1. The distillation molecule outflow pipe 12 is installed on the through-tube 15, and the light molecular separation flowing down from the surface of the condenser 2 flows out from the distillation molecule outflow pipe 12.

[0037] Reference Figure 5 The rotating bracket 3 is composed of a top plate 36, an auxiliary ring 37, a support rod 38, a telescopic sleeve 39 and a telescopic rod 30. The top plate 36 and the auxiliary ring 37 are both arranged to be horizontally distributed, the top plate 36 is arranged to be a circular structure, the top plate 36 and the auxiliary ring 37 correspond to each other up and down and are arranged coaxially, three telescopic sleeves 39 are arranged in an annular array on the top plate 36 and the auxiliary ring 37, the telescopic sleeves 39 on the top plate 36 and the telescopic sleeves 39 on the auxiliary ring 37 correspond to each other one by one, and the telescopic rod 30 is installed inside the telescopic sleeves 39 through elastic members.

[0038] Reference Figure 7 , Figure 8 and Fig. 9, a film-making roller 31, an abutting roller 32, a spiral groove 33, a protective cover shell 34 and a scraper 35 are installed on the rotating bracket 3. The film-making roller 31 is rotatably connected between the two corresponding telescopic rods 30 above and below, and abutting rollers 32 are fixedly installed at both ends of the film-making roller 31. The diameter of the abutting roller 32 is larger than the diameter of the film-making roller 31. Under the connection between the elastic member and the telescopic rod 30, the abutting roller 32 always abuts against the inner wall of the distillation cylinder 1, and the film-making roller 31 always maintains a certain distance from the inner wall of the distillation cylinder 1. The film-making roller 31 is provided with a spiral groove 33 that spirally extends upward. When the mixed liquid is sprayed on the inner wall of the distillation cylinder 1, the film-making roller 31 contacts the mixed liquid. When the film-making roller 31 rotates along the inner wall of the distillation cylinder 1, the spiral groove 33 can bring In order to move the mixed liquid upward for a certain distance and prolong the time the mixed liquid stays on the inner wall of the distillation cylinder 1, a protective cover shell 34 is also installed on the upper and lower corresponding telescopic rods 30, and the protective cover shell 34 is arranged around the film roller 31 on the side away from the inner wall of the distillation cylinder 1. When the film roller 31 rotates, it will drive the mixed liquid to be swung in the direction of rotation. The protective cover shell 34 can prevent the swung mixed liquid from falling on the condenser 2. A scraper 35 is installed on the protective cover shell 34. The scraper 35 is vertically arranged at a certain distance from the inner wall of the distillation cylinder 1, and the scraper 35 is used to scrape the mixed liquid on the inner wall of the distillation cylinder 1 flat.

[0039] When in use, first start the first driving member 4, and the rotating rod 41 on the output shaft of the first driving member 4 drives the rotating bracket 3 to rotate. The abutment roller 32 is always in contact with the inner wall of the distillation cylinder 1 under the action of the elastic member and the telescopic rod 30. When the film roller 31 contacts the mixed liquid on the inner wall of the distillation cylinder 1, the friction force generated by the abutment between the abutment roller 32 and the inner wall of the distillation cylinder 1 causes the abutment roller 32 to rotate. The film roller 31 rotates synchronously driven by the abutment roller 32, and at the same time drives the mixed liquid upward, thereby reducing the downward movement speed of the mixed liquid on the inner wall of the distillation cylinder 1 and extending the residence time of the mixed liquid.

[0040] The mixed liquid is heated on the inner wall of the distillation cylinder 1. The meteorological light molecules generated during heating separate from the mixed liquid and meet the condenser 2. The meteorological light molecules form light molecule liquid when cooled and move downward along the surface of the condenser 2 and flow out from the distillation molecule outflow pipe 12. The remaining mixed liquid flows out from the mixture outflow pipe 11 along the inner wall of the distillation cylinder 1.

[0041] Reference Figure 4 and Figure 6 The liquid spraying assembly 5 includes a liquid inlet main pipe 51, a liquid inlet branch pipe 52 and a nozzle 53. The liquid inlet main pipe 51 is composed of an L-shaped branch pipe and a sleeve pipe, the sleeve pipe is fixedly installed at the bottom of the support plate 14 and is coaxial with the rotating rod 41, an L-shaped through pipe is opened on the rotating rod 41, and the cavity structure inside the sleeve pipe is connected to the L-shaped through pipe, and three liquid inlet branch pipes 52 are arranged on the connecting end of the rotating rod 41 and the top plate 36, and the liquid inlet branch pipes 52 are set as hoses, and nozzles 53 are installed on the liquid inlet branch pipes 52 to spray the mixed liquid onto the inner wall of the distillation cylinder 1.

[0042] When in use, the mixed liquid is introduced into the liquid inlet main pipe 51, and the mixed liquid passes through the L-shaped branch pipe, the inner cavity of the sleeve pipe, the L-shaped through pipe and the liquid inlet branch pipe 52 in sequence to reach the nozzle 53, and the mixed liquid is evenly sprayed on the inner wall of the distillation cylinder 1.

[0043] Reference Figure 4 and Figure 6 The spraying assembly 6 includes an articulated base 61, a rotating wheel 62, a sleeve shaft 63 and a tooth plate 64. The articulated base 61 is fixedly mounted on the top plate 36. Three articulated bases 61 are arranged in an annular array on the top plate 36. The rotating wheel 62 is articulatedly mounted on the articulated base 61. The rotating rod 41 is sleeved with a sleeve shaft 63 that penetrates the top plate 36. Three tooth plates 64 are arranged in an annular array on the sleeve shaft 63. A single tooth plate 64 meshes with teeth on a single rotating wheel 62. The sleeve shaft 63 is connected to a second driving assembly that drives the sleeve shaft 63 to move up and down. The spray head 53 is mounted on the rotating wheel 62.

[0044] When in use, the liquid spraying assembly 5 and the spray cleaning assembly 6 are used in conjunction to clean the inner wall and internal parts of the distillation cylinder 1. Cleaning liquid is introduced into the liquid inlet manifold 51, and the cleaning liquid is sprayed out from the spray head 53. The second driving member 7 drives the sleeve shaft 63 to move up and down, and synchronously, the tooth plate 64 moves up and down, and the rotating wheel 62 meshing with the teeth on the tooth plate 64 rotates around its own axis. While the rotating wheel 62 rotates, it drives the rod and the spray head 53 to adjust the angle, and the inner wall and internal parts of the distillation cylinder 1 are cleaned.

[0045] The implementation principle of a glass-lined distillation device in the embodiment of the present application is:

[0046] When in use, first start the first driving member 4 to drive the rotating bracket 3 to rotate. Under the connection of the elastic member, the telescopic rod 30 is extended and retracted in the telescopic sleeve 39, so that the abutment roller 32 abuts against the inner wall of the distillation cylinder 1. The friction between the abutment roller 32 and the inner wall of the distillation cylinder 1 causes the abutment roller 32 to rotate, and then the film roller 31 fixedly connected to the abutment roller 32 rotates; then the mixed liquid is introduced into the liquid inlet main pipe 51, and the mixed liquid is sprayed out from the nozzle 53. The mixed liquid is evenly sprayed on the inner wall of the distillation cylinder 1, and the mixed liquid moves downward along the inner wall of the distillation cylinder 1.

[0047] When the mixed liquid contacts the rotating film roller 31, the spiral groove 33 on the film roller 31 drives the mixed liquid to move upward a certain distance, thereby extending the time the mixed liquid stays on the inner wall of the distillation cylinder 1. Then, the scraper 35 scrapes the mixed liquid on the inner wall of the distillation cylinder 1 to prevent the mixed liquid from accumulating and ensure the heating distillation speed of the mixed liquid.

For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
