Description

Technical Field

[0001] This utility model relates to the field of separation device technology, specifically to a device for separating acetic acid and propionic acid. Background Technology

[0002] In the carbonyl synthesis of acetic acid, a small amount of propionic acid is generated as a byproduct of the reaction due to the presence of trace amounts of ethanol in the raw material methanol. In order to extract the acetic acid product, a separation device is required.

[0003] While existing separation devices can achieve the desired separation effect, excessive material accumulation in the container during operation leads to inconsistent heat transfer rates, resulting in inconsistent material purity and reduced separation efficiency for acetic acid and propionic acid. Therefore, we propose a device for separating acetic acid and propionic acid. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 An apparatus for separating acetic acid and propionic acid includes a tank 1. A motor 2 is fixedly mounted on the top of the tank 1. An exhaust pipe 3 and a sleeve 7 pass through the outer wall of the tank 1. An air pump 4 is fixedly mounted at the end of the exhaust pipe 3. An electric telescopic rod 5 is provided on the top of the tank 1. A lifting plate 15 is fixedly mounted on the output shaft of the electric telescopic rod 5. A rubber tube 6 is provided on the outer wall of the lifting plate 15. A rotating rod 11 is fixedly mounted on the output shaft of the motor 2. A positioning rod 25 is fixedly mounted on the outer wall of the rotating rod 11. A fixing plate 12 is fixedly mounted on the outer wall of the positioning rod 25. A motor 13 is fixedly mounted on the outer wall of the fixing plate 12. The motor 13 outputs... A rotating rod 24 is fixedly mounted on the output shaft. A gear 23 is fixedly mounted on the end of the rotating rod 24. A turntable 22 is rotatably connected to the end of the positioning rod 25. A receiving hopper 14 is fixedly mounted on the outer wall of the turntable 22. An installation groove 16 is opened on the inner wall of the sleeve 7. A crossbar 17 is fixedly mounted on the inner wall of the installation groove 16. A return spring 18 is sleeved on the outer wall of the crossbar 17. A piston 19 is abutted on the outer wall of the return spring 18. A sealing plug 20 and a round rod 21 are fixedly mounted on both ends of the piston 19, respectively. A sealing plug 10 is fixedly mounted on the round rod 21. A discharge hopper 8 passes through the bottom of the tank body 1. A heater 9 is provided at the bottom of the tank body 1.

[0019] In the above structure, the tank 1, motor 2, exhaust pipe 3, air pump 4, electric telescopic rod 5, hose 6, sleeve 7, heater 9, and receiving hopper 14 are designed so that during use, the user can extend the output shaft of the electric telescopic rod 5 to lower the lifting plate 15, allowing the steel connector to transport the material into the receiving hopper 14. Then, the rotation of the rotating rod 11 ensures that several receiving hoppers 14 are evenly contacted with the heat source, thereby ensuring uniform heating and distillation of the material, thus improving the separation effect of the device. In a preferred embodiment, the inner wall of the turntable 22 is provided with toothed grooves, and the inner wall of the toothed grooves meshes with the outer wall of the gear 23.

[0020] In the above structure, the toothed groove and gear 23 structure allows the user to operate the motor 13 to make the receiving hopper 14 rotate with the turntable 22 after the material is separated, so that the acetic acid is automatically poured into the discharge hopper 8 for discharge, thereby improving the automation of the device.

[0021] In a preferred embodiment, the outer wall of the piston 19 has a limiting hole, and the inner wall of the limiting hole is slidably connected to the outer wall of the crossbar 17, and the outer wall of the sealing plug 20 is slidably connected to the inner wall of the sleeve 7.

[0022] In the above structure, through the sleeve 7 and sealing plug 20, during the operation of the device, the air inside the tank 1 will expand due to high temperature. The increase in air pressure will push the sealing plug 20 and cause the piston 19 to move, so that the high temperature and high pressure air can be discharged through the gap between the mounting groove 16 and the piston 19. This avoids the risk of the tank 1 deforming or even bursting due to the high temperature and high pressure air, thereby improving the safety of the device during operation.

[0023] In a preferred embodiment, both sealing plug 10 and sealing plug 20 are made of rubber, and receiving hopper 14 is connected to the outside world through discharge hopper 8.

[0024] In the above structure, the rubber material has good airtightness, which reduces the rate of heat loss during operation and ensures that the piston 19 can be pushed to move and discharge high-temperature and high-pressure air, so that the device can operate normally.

[0025] In a preferred embodiment, there are several receiving hoppers 14, and all of the several receiving hoppers 14 are evenly distributed along the outer wall of the rotating rod 11.

[0026] In the above structure, the device uses several receiving hoppers 14 to receive materials during operation, thereby enabling the device to complete the separation operation by utilizing the difference in boiling points between acetic acid and propionic acid, thus improving the separation efficiency of the device.

[0027] In a preferred embodiment, the top of the tank 1 is provided with an installation hole, and the inner wall of the installation hole is fixedly assembled with the outer wall of the electric telescopic rod 5.

[0028] In the above structure, through the installation hole and the electric telescopic rod 5, during the heating process of the heater 9, the contraction of the output shaft of the electric telescopic rod 5 ensures that the hose 6 will not melt due to the high temperature and heat of the air, thus allowing the hose 6 to maintain its original state for conveying materials, thereby ensuring that the subsequent use of the device will not be affected.

[0029] In a preferred embodiment, a steel connector is fixedly mounted on the outer wall of the lifting plate 15, and the tank body 1 is connected to the storage tank via a rubber hose 6.

[0030] In the above structure, the tank 1 and the hose 6 are designed so that the material can be transported by the hose 6 during use. After the acetic acid is poured out of the receiving hopper 14, the user can directly transport the material through the hose 6, thus enabling the device to operate continuously.

[0031] In a preferred embodiment, the receiving hopper 14 is made of tempered glass, and there is a 1 cm gap between the mounting groove 16 and the piston 19.

[0032] In the above structure, tempered glass has good high temperature resistance and corrosion resistance, thereby reducing the erosion of the material's chemical properties on the receiving hopper 14 and extending the service life of the receiving hopper 14. Tempered glass can also absorb heat to transfer heat to the material, thereby achieving the effect of separating acetic acid and propionic acid.

[0033] Working principle: First, the user can use the extension of the output shaft of the electric telescopic rod 5 to transport the material to the receiving hopper 14 through the steel connector. Then, the motor 2 is used to rotate the rotating rod 11, so that several receiving hoppers 14 are heated evenly to heat the material. The boiling point of propionic acid decreases under different pressure and humidity conditions. The user can use the air pump 4 to discharge humid air into the tank 1, thereby causing the boiling point of propionic acid to decrease and evaporate, achieving the separation effect. The uniform heating of the material results in a consistent separation degree, which improves the separation effect of the device on acetic acid and propionic acid. During the operation, the high temperature and high pressure air will exert a pushing force on the sealing plug 20, thereby causing the sealing plug 10 to move and allowing the high temperature and high pressure air to be discharged through the gap between the mounting groove 16 and the piston 19. This avoids the risk of deformation or even explosion of the tank 1, thereby improving the safety of the device during operation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
