Technical Field

[0001] This application relates to the field of chemical production technology, and in particular to an equipment for preparing odorless hexanediol. Background Technology

[0002] Odorless hexanediol, especially 1,2-hexanediol, is widely used in the cosmetics industry due to its unique physicochemical properties. This compound has low volatility, high thermal stability, and excellent moisturizing properties. It can form a protective film on the skin surface, effectively locking in moisture and enhancing the moisturizing effect of products.

[0003] Currently, some reactors used in the production of odorless hexanediol primarily discharge material through a bottom discharge valve. While this method is simple to operate, it often results in some residue remaining inside the reactor during the discharge process. This residue not only wastes raw materials but may also contaminate subsequent batches, affecting the purity and quality of the product.

[0004] To address the aforementioned issues, a preparation apparatus for odorless hexanediol has been designed. Utility Model Content

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] This application provides an equipment for preparing odorless hexanediol, which solves the problem in the existing reactors used for producing odorless hexanediol that discharge material through a bottom discharge valve, leaving some residual raw material inside the reactor.

[0038] Please see Figures 1-3 An apparatus for preparing odorless hexanediol includes: a vessel body 1 and a support frame 3 connected to each other, the vessel body 1 having a chamber for containing raw materials, a vessel lid 2 arranged on the vessel body 1, and the vessel body 1 and the vessel lid 2 being connected by a plurality of locking rods 7;

[0039] The vessel body 1 is rotatably mounted on the support frame 3. The support frame 3 is provided with a driving component 4. The driving component 4 is connected to the vessel body 1 and is used to drive the vessel body 1 and the vessel cover 2 to rotate.

[0040] The driving component 4 is provided with a locking plug 5, which is used to lock the driving component 4 and prevent the vessel body 1 from rotating autonomously.

[0041] A stirrer 6 is provided on the lid 2, and the stirrer 6 is used to mix the raw materials inside the pot body 1;

[0042] The bottom of the vessel body 1 is provided with a discharge valve, and the vessel cover 2 is provided with a feed inlet.

[0043] First, the raw materials required for preparing odorless hexanediol are added to the chamber of reactor body 1 through the feed port on reactor lid 2. After the feeding is completed, multiple locking rods 7 are used to tightly connect reactor lid 2 and reactor body 1 to ensure airtightness during the reaction process.

[0044] The drive unit 4 on the support frame 3 is connected to the vessel body 1. When needed, the drive unit 4 can be activated, driving the vessel body 1 and the vessel cover 2 to rotate on the support frame 3 through mechanical transmission, which helps to achieve uniform mixing of raw materials or the realization of specific process requirements.

[0045] When the vessel body 1 does not need to rotate, the locking plug 5 can be inserted into the corresponding position of the drive component 4 to lock the drive component 4, thereby preventing the vessel body 1 from rotating autonomously and ensuring the safety and stability of the equipment.

[0046] The stirrer 6 installed on the lid 2 can mix and stir the raw materials inside the vessel 1 after starting, ensuring uniform distribution and full reaction of the raw materials.

[0047] After the reaction is completed, the reactor body 1 is driven to rotate by the drive component 4. The reactor lid 2 is separated from the reactor body 1 by unlocking the locking rod 7, so that the reactor lid 2 and the stirrer 6 are separated from the reactor body 1, and the raw materials inside the reactor body 1 are completely discharged.

[0048] At the same time, it allows the agitator 6 and the lid 2 to be completely detached from the vessel body 1, so that the operator can thoroughly clean and maintain the inside of the vessel body 1, the agitator 6, and the lid 2.

[0049] By controlling the rotation of the vessel body 1 through the drive component 4 and unlocking the locking rod 7, the vessel cover 2 and the vessel body 1 are separated. This can maximize the product recovery rate, reduce the waste of raw materials, avoid leaving residues inside the vessel body 1, and make the cleaning process of the agitator 6 and the vessel body 1 more convenient and efficient. It also helps to maintain the cleanliness of the equipment and avoid contamination for the next production.

[0050] By driving the reactor body 1 to rotate using the drive unit 4 and stirring the agitator 6, the mixing efficiency of the raw materials can be significantly improved, ensuring the uniformity of the reaction and the quality of the product.

[0051] The rotation of the vessel body 1 increases the flexibility of the equipment, allowing the rotation speed and direction to be adjusted according to different process requirements, thus meeting diverse production needs.

[0052] The locking plug 5 setting can effectively prevent the vessel body 1 from rotating on its own when not needed, ensuring the safety of operators and the stable operation of the equipment.

[0053] It should be noted that the feed inlet in this embodiment is equipped with a sealing cap;

[0054] In addition, the lid 2 is also equipped with a temperature sensor for monitoring the temperature of the internal chamber of the vessel body 1, and a pressure sensor for monitoring the pressure.

[0055] The feed inlet serves as the sole channel for raw materials to enter the reactor body 1. A sealing cap is installed on the feed inlet to prevent external air, moisture, or impurities from entering the reactor, thereby ensuring the purity of the raw materials and the stability of the reaction environment.

[0056] The vessel lid 2 integrates a temperature sensor and a pressure sensor, which are used to monitor the temperature and pressure status of the internal chamber of the vessel body 1 in real time. The temperature sensor accurately reflects temperature changes during the reaction process, providing operators with a basis for adjusting the heating or cooling system. The pressure sensor monitors the pressure inside the vessel, ensuring that the reaction proceeds within a safe range and preventing equipment damage or safety accidents caused by abnormal pressure.

[0057] In one embodiment, the support frame 3 includes two oppositely arranged support rods 31, the support rods 31 being Y-shaped, and the two support rods 31 being connected by a plurality of reinforcing ribs; a support base 32 is provided above the support rods 31, and a rotating rod 33 is rotatably provided inside the support base 32, the two ends of the rotating rod 33 being connected to the vessel body 1 and the driving component 4 respectively.

[0058] The support frame 3 mainly consists of two opposing support rods 31. These two support rods 31 adopt a Y-shaped design, which not only provides a stable support foundation but also optimizes the spatial layout, making the entire equipment more compact. The two Y-shaped support rods 31 are connected by multiple reinforcing ribs. These reinforcing ribs effectively disperse stress and improve the overall load-bearing capacity of the support frame.

[0059] The support base 32 has a rotating rod 33 inside, and the two ends of the rotating rod 33 are connected to the vessel body 1 and the driving component 4 respectively, allowing the vessel body 1 to rotate around the rotating rod 33 under the drive of the driving component 4, thus ensuring the effective transmission of power and the stable rotation of the vessel body.

[0060] In one embodiment, the driving component 4 includes a housing 41 disposed on one side of the support rod 31. Two gears 42 are arranged opposite each other inside the housing 41, with adjacent gears 42 meshing with each other. The gear 42 located at the upper part is fixedly connected to the other end of the rotating rod 33. A drive motor 43 and a reducer 44 are disposed on one side of the housing 41. The output shaft of the drive motor 43 is connected to the input shaft of the reducer 44. The output shaft of the reducer 44 is connected to the gear 42 located at the lower side on one side. The gear 42 located at the lower side on the other side is rotatably connected to the inner side of the housing 41.

[0061] The main body of the drive unit 4 is a housing 41 located on one side of the support rod 31, which provides protection for the internal gear transmission and also ensures the compactness and stability of the entire drive unit.

[0062] Inside the shell 41, two gears 42 are arranged opposite each other. The two adjacent gears 42 mesh with each other to form a stable transmission chain. The upper gear 42 is fixedly connected to the other end of the rotating rod 33. When the upper gear 42 rotates, the rotating rod 33 and the connected vessel body 1 will also rotate.

[0063] On one side of the housing 41, a drive motor 43 and a reducer 44 are provided. The drive motor 43 serves as a power source, and its output shaft is connected to the input shaft of the reducer 44. The function of the reducer 44 is to reduce the speed and increase the torque to ensure that sufficient power is transmitted to the gear transmission mechanism.

[0064] The output shaft of the reducer 44 is connected to the gear 42 located on one side below, while the gear 42 located on the other side below is rotatably connected to the inside of the housing 41. A rotating shaft is provided inside the housing 41 to provide rotational support for the gear.

[0065] When the drive motor 43 starts, its power is transmitted to a lower gear 42 through the reducer 44. When this gear 42 starts to rotate, it drives the entire gear transmission mechanism to rotate through meshing with another gear 42 above. Since the upper gear 42 is fixedly connected to the rotating rod 33, when the other gear 42 above rotates, the rotating rod 33 and the vessel body 1 will also rotate. At the same time, the rotating rod 33 on the other side drives the two gears 42 on the other side to rotate relative to each other.

[0066] Furthermore, in this embodiment, the locking plug 5 includes a guide tube 51 disposed inside one side of the housing 41, and an electric push rod 52 disposed on one side of the housing 41. The piston rod of the electric push rod 52 passes through the guide tube 51 and extends into the housing 41; the piston rod of the electric push rod 52 is slidably engaged with the guide tube 51.

[0067] The piston rod of the electric push rod 52 is provided with a plate 53, and three pins 54 arranged in a ring are provided on the other side of the plate 53. On the upper gear 42, three grooves 55 are provided to match the pins 54.

[0068] The electric push rod 52 is used to drive the pin 54 to insert into the corresponding groove 55 to lock the gear 42 and limit the position of the vessel body 1.

[0069] The guide tube 51 provides a stable sliding path for the piston rod of the electric push rod 52. The piston rod of the electric push rod 52 can pass through the guide tube 51 and extend into the housing 41. The piston rod and the guide tube 51 are in sliding fit, which ensures that the piston rod can move smoothly under the drive of the electric push rod 52.

[0070] On the other side of the plate 53, there are three pins 54 arranged in a ring. These pins 54 are components of the locking plug 5 and are used to cooperate with the grooves 55 on the gear 42 to achieve the locking function.

[0071] On a gear 42 located at the top, there are three grooves 55 that are adapted to the pin 54. The shape, size and position of these grooves 55 are matched with the pin 54 to ensure that the pin 54 can be accurately inserted into them.

[0072] When it is necessary to lock the vessel body 1, the electric push rod 52 is activated, and its piston rod moves inward along the guide tube 51 under the drive of electric force. As the piston rod moves, the plate 53 and the pin 54 also move. When the pin 54 aligns with the groove 55 on the gear 42, the electric push rod 52 continues to push, causing the pin 54 to insert into the groove 55. Once the pin 54 is fully inserted into the groove 55, the gear 42 is locked and can no longer rotate. Since the upper gear 42 is fixedly connected to the rotating rod 33, the vessel body 1 is also limited and cannot rotate further.

[0073] When unlocking is required, the electric push rod 52 is activated in reverse, and the piston rod drives the plate 53 and the pin 54 to move outward. The pin 54 disengages from the groove 55, and the gear 42 and the vessel body 1 can resume rotation.

[0074] Specifically, a limiting disk 56 is also provided on the outside of the piston rod of the electric push rod 52. The limiting disk 56 is located outside the housing 41 and is used to limit the extension or protrusion length of the piston rod of the electric push rod 52.

[0075] The limiting plate 56 is located outside the housing 41, adjacent to the extended end of the electric push rod 52. Its main function is to limit the maximum length of the piston rod of the electric push rod 52 during the extension or retraction process, thereby ensuring that the pin 54 can be accurately and stably inserted into or disengaged from the groove 55 on the gear 42.

[0076] As the piston rod extends outward or retracts inward, the limiting disc 56 moves accordingly and remains outside the housing 41. When the piston rod reaches its predetermined maximum extension length, the limiting disc 56 contacts the side wall of the housing 41, thereby preventing the piston rod from extending further. Similarly, when the piston rod needs to retract, the limiting disc 56 also limits its minimum retraction length, ensuring that the pin 54 can be completely disengaged from the groove 55.

[0077] The stroke of the electric linear actuator can be further limited based on its own displacement control, thereby improving the safety of use.

[0078] In one embodiment, the vessel body 1 and the vessel cover 2 are each provided with a plurality of corresponding positioning holes 8, one side of which is open. The locking rod 7 includes a plurality of positioning rods 71 ​​disposed above the vessel body 1. The top end of the positioning rod 71 passes through the corresponding positioning hole 8 and extends outward. The positioning rod 71 is threaded with a bolt 72 that abuts against the vessel cover 2.

[0079] The positioning hole 8 provides a base for the installation and fixation of the locking rod 7, and also ensures the precise alignment of the vessel body 1 and the vessel lid 2 when closed.

[0080] It is worth noting that one side of the positioning hole 8 is open, which allows the positioning rod 71 to be easily inserted and pulled out, facilitating quick installation and removal by operators.

[0081] The top of the positioning rod 71 has a diameter that matches the positioning hole 8, ensuring that it can smoothly pass through the corresponding positioning hole 8 and extend outward. When the bolt 72 is tightened, it generates downward pressure, pressing the lid 2 tightly against the vessel body 1, thereby achieving a tight seal between the vessel body 1 and the lid 2.

[0082] In practical use, when installing the lid 2, align it with the vessel body 1 so that the corresponding positioning holes 8 on the top and bottom coincide. Then, move the lid 2 down so that the positioning rod 71 is inserted into the corresponding positioning hole 8 on the lid 2.

[0083] Next, bolt 72 is threaded onto the top of positioning rod 71 and gradually tightened. As bolt 72 is tightened, it generates downward pressure, which firmly presses the lid 2 onto the body 1 through positioning rod 71, achieving a tight seal.

[0084] The stirrer 6 in this embodiment includes: a second drive motor mounted on the lid 2; a stirring rod rotatably mounted in the internal cavity of the vessel body 1; the output shaft of the second drive motor is connected to the stirring rod and is used to drive the stirring rod to rotate.

[0085] During the preparation process, drive motor 2 is started, and the output shaft of drive motor 2 begins to rotate. Power is transmitted to the stirring rod through the connection, and the stirring rod rotates in the chamber inside the vessel 1 to stir the raw materials. By adjusting the speed of drive motor 2, the stirring intensity can be controlled to meet the needs of different preparation stages.

[0086] In addition, the stirrer 6 also includes a reducer installed on the lid 2. The output shaft of the drive motor 2 is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the stirring rod. The speed of the stirring rod is reduced and the torque is increased by the reducer 2.

[0087] It should be noted that the inside of the vessel body 1 is provided with a cavity 11, and a plurality of electric heating rods 12 are provided inside the cavity 11.

[0088] The vessel body 1 has an internal cavity 11, which provides installation space for the electric heating rod 12. The electric heating rod 12 is the main component for heating the vessel body, and it is distributed inside the cavity 11 to ensure uniform temperature distribution within the vessel body.

[0089] The electric heating rod 12 converts electrical energy into heat energy through the electrothermal effect, heating the vessel body 1 and the raw materials inside. By controlling the power and heating time of the electric heating rod, the temperature inside the vessel can be precisely adjusted to meet different needs in the preparation process.

[0090] In another embodiment, the vessel body 1 is provided with an inlet pipe and an exhaust pipe for steam circulation, both of which are connected to the cavity 11.

[0091] An air inlet pipe and an exhaust pipe are installed on the vessel body 1. Both pipes are connected to the cavity 11, forming a circulation path for steam within the vessel body 1.

[0092] The inlet pipe is used to introduce steam into the vessel, which can be heated water vapor or other inert gases, for further heating of the vessel and the raw materials inside. The steam enters cavity 11 through the inlet pipe, improving heating efficiency.

[0093] The exhaust pipe is used to expel the steam in cavity 11 and maintain the continuous flow of hot steam.

[0094] It should be noted that either the electric heating rod 12 or the hot steam can be used to heat the vessel body 1.
