Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, and in particular relates to a rotary lifting reaction vessel. Background Technology

[0002] A reaction vessel is a container for carrying out physical or chemical reactions. Through structural design and parameter configuration of the vessel, the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process can be achieved.

[0003] Traditional reactors typically consist of a reactor body, a reactor lid, and feed ports and pipelines for adding various chemical raw materials. They lack lifting and rotating functions. Due to inherent structural defects, when the reactor body needs to be cleaned after the reaction is complete, it must be moved downwards to below the stirring blades before cleaning can be performed. This process is inefficient and inconvenient.

[0004] Chinese patent application CN202322176055.5 discloses a novel rotary lifting reactor, comprising a support frame, a U-shaped frame fixedly connected to the top of the support frame, a reactor lid fixedly connected to the outer surface of the U-shaped frame, a stirring motor fixedly connected to the top of the reactor lid, a stirring rod fixedly connected to one end of the stirring motor, stirring blades fixedly connected to the outer surface of the stirring rod, a fixing plate rotatably connected to the outer surface of the support frame, and two fixing rods fixedly connected to the outer surface of the fixing plate, with fixing frames fixedly connected to the opposite faces of the two fixing rods. The advantages of this invention are: the motor of this device rotates a threaded rod via a second and third bevel gear, thereby driving a slide to slide within the support frame, realizing the lifting and lowering operation of the reactor lid; when the reactor body needs to be rotated, the rotation of the reactor body is achieved by rotating the handwheel to drive the connecting parts, facilitating material discharge and cleaning, and is convenient, quick, and highly efficient.

[0005] In the aforementioned prior art, even if the vessel lid does not rise and detach from the vessel body, the handwheel can still be operated to rotate the vessel body, thereby damaging the stirring device on the lid. Similarly, when the vessel body is not reset, the lid can also be operated to lower, which will also damage the stirring device. Summary of the Invention

[0006] The purpose of this invention is to provide a rotary lifting reactor that partially solves or alleviates the above-mentioned deficiencies in the prior art, and can achieve interlocking of reactor body rotation and reactor lid lifting to avoid equipment damage.

[0007] To solve the aforementioned technical problems, the present invention specifically adopts the following technical solution: The first aspect of this utility model is to provide a rotary lifting reactor, including a reactor body, a reactor lid, a support, and a mounting frame; the mounting frame is connected to the support via a rotating shaft; the reactor body is fixed on the mounting frame and can rotate with the rotating shaft; the support is provided with a slide that can be raised and lowered along the support column; the reactor lid is connected to the slide and can be raised and lowered with the slide; the reactor lid is provided with a stirring device that can extend into the reactor body; it also includes a lifting drive mechanism for driving the slide to rise and fall and a rotating mechanism for driving the mounting frame to rotate; it also includes an interlocking mechanism acting on the lifting drive mechanism and the rotating drive mechanism, the interlocking mechanism ensuring that the reactor body cannot rotate before the slide rises to its position, and that the reactor lid cannot be lowered before the reactor body returns to its original position.

[0008] Furthermore, the interlocking mechanism includes an interlocking rod that can rise and fall with the slide and a keyhole that passes through the rotating shaft; after the interlocking rod is inserted into the keyhole, the interlocking rod can only be disengaged from the keyhole when the slide is raised to the correct position, allowing the vessel body to rotate; and only when the vessel body is reset can the interlocking rod be inserted back into the keyhole, allowing the slide to drive the vessel lid to fall.

[0009] Furthermore, the rotating shaft is provided with a square column section; the keyhole is opened on the square column section; the interlocking rod is made of engineering plastic and its lower end is wedge-shaped.

[0010] Furthermore, the lifting drive mechanism includes a lead screw vertically disposed in the column and a threaded sleeve that engages with the lead screw; an axial sliding groove is provided on the side wall of the column, and the slide extends into the column through the sliding groove and connects with the threaded sleeve; it also includes a lifting motor for driving the lead screw to rotate.

[0011] Furthermore, the rotary drive mechanism includes a bevel gear I fixedly sleeved on the rotating shaft and a bevel gear II meshing with the bevel gear I; it also includes a handwheel coaxial with the bevel gear II and a handle fixed to the handwheel.

[0012] Furthermore, the gear ratio between the bevel gear I and the bevel gear II is 2:1 to 3:1.

[0013] Furthermore, the connection point between the rotating shaft and the mounting bracket is located directly above the center of gravity of the vessel.

[0014] Furthermore, the vessel body has a sandwich structure, and cold or hot media can be introduced into the sandwich to cool or heat the materials inside the vessel body.

[0015] Furthermore, the stirring device includes a stirring rod and stirring blades; the stirring rod is made of 304 stainless steel and is covered with a polytetrafluoroethylene tube, and the stirring blades are made of polytetrafluoroethylene.

[0016] Furthermore, the bracket includes an I-shaped base on which a braked caster wheel is mounted.

[0017] Beneficial effects: The rotary lifting reactor with the above structure has an interlock mechanism that uses an interlock rod and a pivot lock to enforce the operation sequence of "lifting the lid → rotating → resetting → lowering the lid". This avoids conflicts between the reactor body rotation and lid lifting due to misoperation, and prevents risks such as collisions of the stirring device and failure of the reactor body seal. In addition, the design of the square column section and the wedge-shaped interlock rod ensures accurate positioning and smooth insertion.

[0018] The rotating shaft is connected directly above the center of gravity of the vessel, allowing the vessel to automatically reset under gravity, reducing vibration and eccentric load during rotation, ensuring stable operation of the equipment, and extending its service life.

[0019] The lifting drive mechanism uses a screw drive, which can precisely control the lifting of the vessel lid, facilitating material addition, equipment cleaning and maintenance; the rotary drive mechanism uses bevel gears with a gear ratio of 2:1-3:1 and a handwheel to achieve labor-saving rotation, making it convenient for operators to adjust the angle of the vessel body and perform operations such as material pouring and observation.

[0020] The vessel jacket can be circulated with hot or cold media to heat or cool the materials, with a wide temperature control range and good uniformity; the stirring device is made of corrosion-resistant 304 stainless steel and polytetrafluoroethylene, which can adapt to a variety of chemical media, effectively stir materials, and improve reaction efficiency.

[0021] The I-shaped base, combined with braked casters, makes the reactor easy to move in the laboratory or workshop and can be quickly fixed in place after reaching the designated location, adapting to the needs of different working scenarios.

[0022] The design of the lid being adjustable and the body being rotatable makes the internal space of the equipment easier to expose, facilitating internal cleaning and material disposal. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this document, "and / or" includes any and all combinations of one or more of the listed related items.

[0033] In this article, "multiple" means two or more, that is, it includes two, three, four, five, etc.

[0034] Example 1: like Figure 1 , Figure 4 As shown, this utility model provides a rotary lifting reactor, including a reactor body 4, a reactor cover 5, a support 1, and a mounting frame 2; the mounting frame 2 is connected to the support 1 via a rotating shaft 9; the reactor body 4 is fixed on the mounting frame 2 and can rotate with the rotating shaft 9; the support 1 is provided with a slide 3 that can be raised and lowered along the support 1 column 11; the reactor cover 5 is connected to the slide 3 and can be raised and lowered with the slide 3; the reactor cover 5 is provided with a stirring device 6 that can extend into the reactor body 4; it also includes a lifting drive mechanism for driving the slide 3 to rise and fall and a rotating mechanism for driving the mounting frame 2 to rotate; it also includes an interlocking mechanism acting on the lifting drive mechanism and the rotating drive mechanism, the interlocking mechanism ensuring that the reactor body 4 cannot rotate before the slide 3 rises to the position, and the reactor cover 5 cannot be lowered before the reactor body 4 is reset.

[0035] In this invention, an interlocking device is used to interlock the lifting drive mechanism and the rotating drive mechanism, ensuring that if either the vessel body 4 or the vessel lid 5 is not in the correct position, the other cannot move. For example, under normal circumstances, the vessel lid 5 needs to be raised to disengage the stirring device 6 from the vessel body 4 before the vessel body 4 can rotate. When the vessel lid 5 is lowered, the vessel body 4 needs to be returned to its initial position, i.e., in a vertical state. This ensures that there will be no collision between the equipment, especially between the stirring device 6 and the vessel body 4, thus protecting the equipment safety.

[0036] Specifically, the interlocking mechanism in this embodiment includes an interlocking rod 15 that can rise and fall with the slide 3 and a keyhole that passes through the rotating shaft 9; after the interlocking rod 15 is inserted into the keyhole, the interlocking rod 15 can only be disengaged from the keyhole when the slide 3 rises to the position, so that the vessel body 4 can rotate; and only when the vessel body 4 is reset can the interlocking rod 15 be inserted into the keyhole again, so that the slide 3 can drive the vessel cover 5 to fall.

[0037] The interlock mechanism is the core safety feature of the rotary lifting reactor. It uses a mechanical structure to forcibly restrict the operating sequence, preventing damage to the equipment due to misoperation. In this embodiment, the reactor body 4 can only rotate after the reactor lid 5 is fully raised (the slide 3 is in position), the interlock rod 15 disengages from the lock, and the rotating shaft 9 unlocks. Conversely, the reactor lid 5 can only descend after the reactor body 4 has reset (returned to its initial position), the lock is aligned with the interlock rod 15, the interlock rod 15 inserts into the lock, and the slide 3 can then descend. The interlock mechanism's operating procedure is as follows: 1. In the initial state, the interlocking rod 15 is inserted into the lock hole of the rotating shaft 9, the vessel body 4 is locked and cannot rotate; the slide 3 can rise freely.

[0038] 2. When it is necessary to raise the lid 5, the lifting drive mechanism drives the slide 3 to rise, and the interlocking rod 15 moves upward accordingly.

[0039] 3. Unlock and rotate. When the slide 3 is raised to the highest point, the interlock rod 15 is completely disengaged from the lock, the rotating shaft 9 is unlocked, and the vessel body 4 can be rotated.

[0040] 4. Rotate the vessel body 4. The operator turns the handwheel 7 to rotate the vessel body 4 around the axis (for example, rotate it 150° in a certain direction).

[0041] 5. Reset and lock. After the vessel body 4 rotates back to its initial position, the keyhole aligns with the interlocking rod 15, and the interlocking rod 15 can be inserted into the keyhole.

[0042] 6. Lower the lid 5. After the interlocking rod 15 is inserted into the keyhole, the rotating shaft 9 is locked again, preventing the vessel body 4 from rotating.

[0043] More specifically, the pivot 9 is provided with a square column section 91; the keyhole is opened on the square column section 91; the interlocking rod 15 is made of engineering plastic and its lower end is wedge-shaped.

[0044] The square column section 91 facilitates keyhole drilling and increases the keyhole opening area. The lower end of the interlocking rod 15 is wedge-shaped (sloping). When the slide 3 lowers the interlocking rod 15 and approaches the keyhole, the wedge-shaped slope can generate a guiding force with the edge of the keyhole. Even if there is a slight deviation between the two in the horizontal direction, they can be automatically aligned by the pressure of the slope, avoiding the interlocking rod 15 being unable to be inserted into the keyhole due to installation errors. In addition, the interlocking rod 15, made of engineering plastic, has good wear resistance and low hardness. It is not easy to wear down the edge of the keyhole after long-term insertion and removal, nor is it easy to damage the pivot 9. It also has a certain degree of elasticity, which can be elastically deformed in the event of a slight impact, avoiding rigid jamming.

[0045] In this embodiment, the lifting drive mechanism includes a lead screw 10 vertically disposed within a column 11 and a threaded sleeve 12 threadedly engaged with the lead screw 10. An axial groove is formed on the side wall of the column 11, and the slide 3 extends into the column 11 through the groove and connects to the threaded sleeve 12. It also includes a lifting motor 8 for driving the lead screw 10 to rotate. When the motor drives the lead screw 10 to rotate, the threaded sleeve 12 moves axially along the lead screw 10 due to the action of the threaded pair, converting the rotational motion into linear motion, thereby driving the slide 3 and the vessel lid 5 and stirring device 6 fixed on the slide 3 to rise and fall. The lead screw 10 has a self-locking function; even if power is lost during lifting, the threaded sleeve 12 will not slip due to load, protecting the equipment safety.

[0046] In order to provide more stable support for the slide 3 during lifting, this embodiment uses two upper and lower screw sleeves 12, which can move synchronously under the action of the lead screw 10.

[0047] The width of the groove on the side wall of the column 11 matches the width of the carriage 3, ensuring that the carriage 3 can only move axially along the column 11 and preventing circumferential rotation. The carriage 3 is rigidly connected to the threaded sleeve 12 by bolts or keyways to ensure synchronous movement. The connection parts need to be strength checked to avoid loosening due to frequent starts and stops.

[0048] In this embodiment, the rotary drive mechanism includes a bevel gear I13 fixedly sleeved on the rotating shaft 9 and a bevel gear II14 meshing with the bevel gear I13; it also includes a handwheel 7 coaxial with the bevel gear II14 and a handle fixed on the handwheel 7.

[0049] Two bevel gears intersect on their axes to transmit power between the intersecting shafts. Handwheel 7 drives bevel gear II to rotate, and bevel gear II meshes with bevel gear I fixed on rotating shaft 9. Both bevel gears are vertically arranged, allowing handwheel 7 to be operated from the side of the vessel body 4. Compared to the electric rotating mechanism, the manual handwheel 7 is more suitable for pouring materials according to the material conditions inside the vessel body 4, and it requires no electricity, making it suitable for environments without power supply or in explosion-proof environments.

[0050] Furthermore, the gear ratio between bevel gear I13 and bevel gear II14 is 2:1 to 3:1. The gear ratio (number of teeth on the driven gear / number of teeth on the driving gear) determines the torque amplification factor. When the gear ratio is 2:1, the handwheel 7 rotates 2 revolutions, and the shaft 9 rotates 1 revolution, resulting in an output torque that is twice the input torque. When the gear ratio is 3:1, the handwheel 7 rotates 3 revolutions, and the shaft 9 rotates 1 revolution, resulting in a 3-fold amplification of the output torque. With this configuration, rotating the handwheel 7 to drive the vessel body 4 requires less effort.

[0051] In this embodiment, the connection point between the rotating shaft 9 and the mounting bracket 2 is located directly above the center of gravity of the vessel body 4. The purpose of this is to allow the vessel body 4 to return to a vertical position under its own gravity through eccentricity. Furthermore, when the vessel body 4 returns to a vertical position under gravity, the lock hole of the square column section 91 of the rotating shaft 9 automatically aligns with the interlocking rod 15, eliminating the need for precise manual positioning.

[0052] The vessel body 4 has a jacketed structure, through which cold or hot media can be introduced to cool or heat the materials inside. When heating is required, heat transfer oil or steam is introduced to raise the material temperature through heat conduction; when cooling is required, cooling water or chilled brine is introduced to absorb heat from the material and lower its temperature. The flow of the media is controlled by solenoid valves at the inlet and outlet of the jacket, thereby switching between heating and cooling modes.

[0053] To prevent corrosion from materials, the stirring device 6 includes a stirring rod and stirring blades; the stirring rod is made of 304 stainless steel and is covered with a polytetrafluoroethylene tube, and the stirring blades are made of polytetrafluoroethylene.

[0054] For greater stability and ease of transfer, the bracket 1 also includes an I-shaped base 102, on which a braked caster wheel 103 is mounted.

[0055] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
