Description

Technical Field

[0001] This utility model relates to the field of distillation technology, and in particular to a unidirectional condenser centrifugal molecular distillation device. Background Technology

[0002] Scraped film molecular distillation equipment is widely used in modern industrial production. It forms a thin, uniform liquid film through the coordinated action of a scraper and a heating surface. The advantages of this equipment include short heating time for materials, reduced risk of thermal decomposition, high production efficiency, and the ability to operate continuously. However, it also has some disadvantages, such as a large footprint, reliance on auxiliary systems for heating oil and coolant, potential risk of media oxidation and leakage, relatively complex operation, and higher equipment costs.

[0003] Currently, there are problems such as the large size of the heating device, which increases the required floor space, and uneven distribution of the mixed liquid during centrifugation, which affects the distillation efficiency.

[0004] Therefore, the above problems need to be addressed. Utility Model Content

[0005] Therefore, this utility model was made in view of the above problems. The purpose of this utility model is to solve the problem of increasing the longitudinal distillation area and reducing the circumferential usable area by changing the internal structure of the centrifuge chamber. This utility model achieves the above objective through the following technical solution:

[0006] A unidirectional condensing centrifugal molecular distillation apparatus includes: an outer casing, a base, a hollow shaft torque motor, and a feed inlet;

[0007] The outer cover is cylindrical and fixed on the base, which is located at the lower end of the outer cover and is used to support the entire device.

[0009] The light liquid outlet is fixed at the lower end of the base and communicates with the light liquid collection tank. The heavy liquid outlet is fixed at the lower end of the base and communicates with the heavy liquid collection tank. The fixing plate is located at the upper end of the hollow shaft torque motor and contacts and limits the contact with the upper surface of the outer cover to prevent the hollow shaft torque motor from shaking when it rotates. The inner ring of the bearing contacts and limits the contact with the lower end of the hollow shaft torque motor, and the outer ring of the bearing contacts and limits the contact with the lower end of the centrifuge section.

[0010] The light liquid collection tank is fixed in the middle of the base, its outer wall is in contact with the inner wall of the heavy liquid collection tank, and the light liquid collection tank is connected to the light liquid outlet and fixedly supports the conical condenser. The heavy liquid collection tank is fixed on the base, its inner wall is in contact with the outer wall of the light liquid collection tank, and the heavy liquid collection tank is connected to the heavy liquid outlet.

[0011] The conical condenser is a conical cylinder with a certain angle of inclination on its outer surface. It is wider at the top and narrower at the bottom to facilitate the downward flow of liquid. The upper end of the conical condenser is fixed in contact with the outer wall of the centrifuge section, and its lower end is fixed in the middle part of the inner surface of the light liquid collection tank. It is connected to the first wire to provide power for cooling, which is used to condense light molecules to form light liquid and allow the light liquid to flow into the light liquid collection tank along its conical surface.

[0012] The four distillation bodies are fixed to the lower end of the outer wall of the centrifuge and connected to the centrifuge. They distill the mixture after centrifugation, causing light molecules to move towards the conical condenser and heavy liquid to flow back. The centrifuge is fixed to the lower end of the hollow shaft torque motor for storing and limiting the mixture. The first wire is fixed inside the hollow shaft torque motor for controlling the cooling of the conical condenser.

[0013] The second wire is fixed to the outer ring of the hollow shaft torque motor and is used to control the heating of the four distillation bodies. The spiral conveyor plate is located inside the centrifuge section and is in contact with the mixture. The mixture moves downward along its trajectory. When the spiral structure rotates and centrifuges, it centrifuges the mixture more thoroughly and also reduces the area occupied by the centrifuge section laterally.

[0014] The base includes: support legs and an annular groove. The support legs are fixed to the lower surface of the base to support the entire device. The annular groove is located on the outer ring of the upper surface of the base and is fixed to the outer cover.

[0015] The outer cover includes a hollow section located on the upper surface of the outer cover, which is fixed to the upper part of the hollow shaft torque motor and contacts and limits the movement of the lower surface of the fixing plate.

[0016] The hollow shaft torque motor includes: a motor body, a rotating part, and a valve. The motor body is located at the upper end of the hollow shaft torque motor and drives the rotating part to rotate. Its lower end is in contact with and fixed to the hollow part of the outer casing. The rotating part is fixed inside the upper end of the motor body. Its outer surface is in contact with and fixed to the inner wall of the centrifugal part and drives it to rotate. The valve is fixed on the feed inlet, the light liquid outlet, and the heavy liquid outlet to control the vacuum seal inside the outer casing.

[0017] The centrifuge section includes: a rotor, a liquid storage tank, and an opening. The rotor is located in the middle of the centrifuge section, with its inner wall in contact and fixed to the rotating part, and its outer wall in contact and fixed to the spiral conveyor plate. The liquid storage tank is located on the outermost side of the centrifuge section and is in contact with and limited by the spiral conveyor plate. The opening is located on the outer wall of the liquid storage tank, and its opening size is fixed, allowing the mixed liquid to be spun out through the opening.

[0018] The rotor includes: a rotating plate, a rotor base, and a rotor body. The rotating plate is located at the lower end of the rotor and rotates along the path of the rotating plate when the rotor rotates. The rotor base is located at the lower end of the rotating plate and contacts and limits the movement with the inner ring of the bearing. The rotor body is located at the upper end of the rotating plate, where the screw conveyor plate is fixed, and the inner wall of the rotor body contacts and is fixed with the rotating part.

[0019] The liquid storage tank includes: a chute, a liquid storage tank control unit, an outer wall of the liquid storage tank, and a porous distributor. The chute is located inside the liquid storage tank, contacts and limits the rotation of the rotating plate, and causes the rotor to rotate along its path. The liquid storage tank control unit is located in the middle of the liquid storage tank, its inner surface contacts and limits the rotation of the bearing outer ring, and its lower surface contacts and fixes the upper surface outer ring of the conical condenser. The outer wall of the liquid storage tank is located at the upper end of the liquid storage tank and contacts and limits the rotation of the spiral conveyor plate. The porous distributor is located on the lower surface of the opening and is made of porous metal sponge material, used to control the flow rate of the mixture.

[0020] The distillation body includes: a connecting opening, a through-hole, a reflux port, an upper wall, an inclined distillation plate, and a lower wall. The connecting opening is located at the outer end of the upper surface of the distillation body and is fixed in contact with the lower surface of the opening. It is used to receive the mixture after centrifugation. The through-hole is located in the middle of the distillation body and is in contact with and limited by the conical condenser. The reflux port is located at the lower end of the outer ring of the distillation body. The heavy liquid can flow into the heavy liquid collection tank through the reflux port. The upper wall of the body is located on the upper surface of the distillation body and is used to limit the splashing of the mixture. The inclined distillation plate is located at the inner outer ring of the distillation body. Its shape is a right triangle, and its hypotenuse is the distillation surface. The inclined surface distillation is more thorough and can reduce the downward flow velocity of the mixture. The distillation of the mixture can make the light liquid move towards the conical condenser, while the heavy liquid flows along the surface of the condenser to the lower wall of the body.

[0021] The lower wall of the main body is located on the lower surface of the distillation body. Its surface has a certain angle, with the middle part being higher and the surrounding area being lower. The purpose is to allow the heavy liquid on its surface to move to the surrounding return ports through the angle of its surface, and finally flow out of the return ports into the heavy liquid collection tank.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. This utility model changes the centrifugal rotor to a spiral structure, which reduces the machine's footprint, increases the centrifugal area, and increases centrifugal efficiency.

[0024] 2. This utility model changes the liquid outlet to a four-way outlet, which prevents splashing of the mixed liquid and makes the mixed liquid distribution more uniform;

[0025] 3. This utility model uses an inclined distillation plate inside the distillation body to connect with the centrifuge section to complete the centrifugal distillation of the mixture, which enhances the overall efficiency of the work.

[0026] 4. The four distillation bodies have openings facing the same direction, all directly opposite the conical condenser. The machine components are compactly arranged, reducing the area occupied by the machine's horizontal surface. Attached Figure Description

[0068] The liquid storage tank 132 is located on the outermost side of the centrifuge section 13 and is in contact with and limited by the spiral conveyor plate 16.

[0069] The opening 133 is located on the outer wall of the liquid storage tank 132, and its opening size is fixed, allowing the mixture to be spun out through the opening 133.

[0070] like Figure 7 As shown, the rotor 131 includes: a rotating plate 41, a rotor base 42, and a rotor body 43;

[0071] The rotating plate 41 is located at the lower end of the rotor 131 and rotates along the path of the rotating plate 41 when the rotor 131 rotates.

[0072] The rotor base 42 is located at the lower end of the rotating plate 41 and is in contact with and limited by the inner ring of the bearing 8.

[0073] The rotor body 43 is located at the upper end of the rotating plate 41, the spiral conveying plate 16 is fixed thereon, and the inner wall of the rotor body 43 is in contact with and fixed to the rotating part 32.

[0074] like Figure 8 As shown, the liquid storage tank 132 includes: a chute 44, a liquid storage tank control unit 45, an outer wall of the liquid storage tank 46, and a porous distributor 47;

[0075] The chute 44 is located inside the liquid storage tank 132, contacts and limits the rotation plate 41, and causes the rotor 131 to rotate along its path when it rotates.

[0076] The liquid storage tank control unit 45 is located in the middle of the liquid storage tank 132. Its inner surface contacts and limits the outer ring of the bearing 8, and its lower surface contacts and fixes the outer ring of the upper surface of the conical condenser 11.

[0077] The outer wall 46 of the liquid storage tank is located at the upper end of the liquid storage tank 132 and is in contact with and limited by the spiral conveyor plate 16.

[0078] The porous distributor 47 is located on the lower surface of the opening 133 and is made of porous metal sponge material, used to control the flow rate of the mixture.

[0079] like Figure 9 As shown, the distillation body 12 includes: a connecting opening 121, a through-hole 122, a reflux port 123, an upper wall 124, an inclined distillation plate 125, and a lower wall 126.

[0084] The inclined distillation plate 125 is located inside the outer ring of the distillation body 12. Its shape is a right triangle with its hypotenuse as the distillation surface. The inclined distillation is more thorough and can reduce the downward flow velocity of the mixture. The distillation of the mixture can cause the light liquid to move towards the conical condenser 11, while the heavy liquid flows along the surface of the condenser towards the lower wall 126 of the body.

[0085] The lower wall 126 of the main body is located on the lower surface of the distillation body 12. Its surface has a certain angle of inclination, with the middle part being higher and the surrounding area being lower. The purpose is to allow the heavy liquid on its surface to move to the surrounding return ports 123 through the angle of inclination of its surface, and finally flow out of the return ports 123 and into the heavy liquid collection tank 10.

[0086] The working principle of this utility model:

[0087] This utility model is applicable to the separation of light and heavy component mixtures. The mixture enters the spiral conveyor plate 16 in the centrifuge section 13 through the feed port 4, and the rotor 131 is driven to rotate by the hollow shaft torque motor 3 to fully centrifuge the mixture.

[0088] When the mixture falls to the bottom through the path of the spiral conveyor plate 16, it spirals out of the centrifuge section 13 through the opening 133 (the storage tank 132 is in a fixed state, so the opening 133 only spirals out the centrifuged mixture in one direction), and the mixture is decelerated by the porous distributor 47, so that the centrifuged mixture moves to the inclined distillation plate 125 inside the rotating distillation body 12 for distillation.

[0089] Meanwhile, the light component molecules move towards the inclined surface of the central conical condenser 11 through distillation and condense into a stream on its surface (the free path of the light component molecules is greater than or equal to the radius of the conical condenser 11), and then flow into the light liquid collection tank 9 through its inclined surface. The side of the light liquid collection tank 9 is connected to the light liquid outlet 5, which can flow out to the outside through the light liquid outlet 5.

[0090] Since the free path of the heavy liquid is smaller than that of the light component molecules, the heavy liquid flows along the surface of the inclined distillation plate 125 to the surface of the lower wall 127 of the main body. Because the lower wall 127 of the main body has an inclination angle, the heavy liquid eventually flows to the return port 123 and enters the heavy liquid collection tank 10. The lower part of the heavy liquid collection tank 10 is connected to the heavy liquid outlet 6, which can flow out to the outside.
