Description

Technical Field

[0001] This utility model relates to the field of active pharmaceutical ingredient (API) production technology, specifically to an extraction device for a reaction vessel lid. Background Technology

[0002] In the production of active pharmaceutical ingredients (APIs), the reaction vessel is a crucial reaction container. Its main function is to provide a sealed space for the chemical reaction and to promote uniform mixing of materials through physical stirring, ensuring the reaction proceeds fully and ultimately yielding the target product. After each production run, reactants, byproducts, or catalysts inevitably remain on the inner wall of the vessel and on the stirring components. If these residues are not removed, they will directly affect the purity of the next batch of materials, the reaction process, and even the quality and safety of the product. Therefore, the interior of the reaction vessel must be thoroughly cleaned after each batch of production.

[0003] To perform internal cleaning, the reactor lid needs to be opened. Currently, the widely used locking method between the lid and the reactor body primarily relies on multiple sets of high-strength bolts evenly distributed along the flange at the reactor opening. Because reactor lids are typically made of heavy metal and integrate accessories such as stirring actuators, sight glasses, gauges, and lugs, their weight is often considerable. After the bolts are released, multiple operators need to work together to safely lift the heavy lid off the reactor body and move it to a designated area. After cleaning, the same manpower is required to move and lift the lid back onto the reactor body.

[0004] While in practice, electric or pneumatic wrenches are often used instead of manual wrenches to reduce the labor intensity of bolt removal and installation, which improves the speed of bolt removal and installation to some extent, this only solves the efficiency problem of bolt removal and installation. It does not solve the problem of the weight of the reactor lid itself and the need for manual handling. The handling process requires a lot of manpower and affects the cleaning efficiency of the reactor. Utility Model Content

[0005] The purpose of this invention is to provide a reactor lid extraction device that can assist in moving the lid during reactor cleaning, reducing manpower consumption, facilitating reactor cleaning, and improving cleaning efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a reaction vessel lid extraction device, comprising a column and a cable assembly, wherein the cable assembly comprises a first cable, a guide wheel, and a second cable, one end of the first cable is connected to the output shaft of a winch, and the other end passes around the guide wheel located at the upper end of the column and is connected to a lifting disc, and several second cables are arranged in an array along the center of the lifting disc on its lower end surface, and the lower end of the second cable is provided with a connector for connecting to the lid lug, and the winch is located on one side of the lower end of the column.

[0007] A further improvement of this utility model is that the column is provided with a mounting bracket, and the guide wheel is disposed on the mounting bracket.

[0008] A further improvement of this utility model is that the mounting frame includes support rods symmetrically arranged at the upper end of the column, and two guide wheels are provided and rotatably connected to one end of the two support rods respectively. The first steel cable passes around the two guide wheels in sequence and is connected to the lifting plate.

[0009] A further improvement of this utility model is that the support rod extends upward in a trumpet shape, and the guide wheel is located at the extended end of the support rod.

[0010] A further improvement of this invention is that the output shaft of the winch and the rotation shaft of the guide wheel are arranged parallel to each other.

[0011] A further improvement of this utility model is that the guide wheel has an anti-detachment groove on its surface, and the first steel cable runs within the anti-detachment groove.

[0012] A further improvement of this utility model is that the second steel cable has at least three strands.

[0013] A further improvement of this utility model is that the connecting component is a spring hook or a hook.

[0014] A further improvement of this utility model is that the lower end of the column is rotatably connected to the base cylinder and fixed by a fastener.

[0015] A further improvement of this utility model is that the lower end of the column is provided with a through hole in the radial direction, and the wall of the base cylinder is provided with at least two pairs of adjustment holes that cooperate with the through hole, and the fixing member passes through the adjustment hole and the through hole.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention, by incorporating a steel cable assembly, enables the vessel lid to be moved with the assistance of a winch during reactor cleaning, reducing manpower consumption, facilitating reactor cleaning, and improving cleaning efficiency.

[0018] This utility model, by setting up a lifting plate, can be equipped with multiple second steel cables to connect with the kettle lid, which can increase the load-bearing capacity, improve the stability of handling compared to a single steel cable connection, and prevent the kettle lid from tipping over during handling.

[0019] The column of this utility model is rotatably connected inside the base cylinder and fixed by a fastener. After the lid is lifted, the lid can be moved away from directly above the lid by adjusting the rotation angle of the column, which facilitates cleaning of the lid and removes any obstruction from the lid, thus improving the cleaning effect and efficiency.

[0023] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1: Combination Figures 1-2 It is known that a reaction vessel lid extraction device includes a vertically fixed column 1 and a steel cable assembly. The steel cable assembly includes a first steel cable 2, a guide wheel 3, and a second steel cable 4. One end of the first steel cable 2 is connected to the output shaft (specifically, a winding drum) of a winch 5, and the other end passes over the guide wheel 3 located at the upper end of the column 1 and is connected to a lifting plate 6. Several second steel cables 4 are arranged in an array along the center of the lifting plate 6 on its lower end surface. The lower end of the second steel cable 4 is provided with a connector 7 that is connected to a pre-set lug on the top or side wall of the vessel lid. The winch 5 is located on one side of the lower end of the column 1.

[0025] A mounting bracket is provided on the column 1, and the guide wheel 3 is mounted on the mounting bracket. The output shaft of the winch 5 is parallel to the axis of rotation of the guide wheel 3. Preferably, there are at least three second steel cables 4. The central axis of the winding drum that drives the first steel cable 2 to be wound by the winch 5 is parallel in space to the central axis of rotation of the guide wheel 3 around it. When the first steel cable 2 reaches the guide wheel 3, since the axis of rotation of the guide wheel 3 is parallel to the axis of rotation of the winding drum, the first steel cable 2 can smoothly and naturally change direction within the groove of the guide wheel 3 without undergoing forced twisting around its own axis.

[0026] The rigid side connection of the column 1 (e.g., by welding or by flange and high-strength bolts) includes a mounting base plate. One end of the mounting base plate has a connecting arc that mates with the outer cylindrical surface of the cylindrical column 1, thereby increasing the effective connection area and improving connection stability. This mounting base plate is used to fix the winch 5 in place. To enhance structural rigidity and resistance to deformation, at least one reinforcing rib is preferably provided between the mounting base plate and the column 1. This connection structure has sufficient strength and rigidity to effectively bear the weight and working load of the winch 5 and resist the vibration and torsional torque generated during its operation, ensuring the long-term stability and reliability of the winch 5 installation.

[0027] The mounting frame includes symmetrically fixed support rods 8 welded or bolted to the upper end of the column 1. Two guide wheels 3 are provided, each rotatably connected to one end of a support rod 8. The first steel cable 2 passes over the two guide wheels 3 sequentially and connects to the lifting plate 6. The segmented guidance using two guide wheels 3 reduces the risk of cable slippage compared to a single guide wheel.

[0028] The support rod 8 extends upward in a trumpet shape, and the guide wheel 3 is located at the extended end of the support rod 8. This ensures that the two guide wheels 3 are spaced a certain distance apart in the horizontal direction. There are two guide wheels 3, which are rotatably connected to the extended ends (i.e., the far ends after opening) of the two support rods 8 via axles and bearings, respectively.

[0029] The guide wheel 3 has an anti-slip groove on its surface, within which the first steel cable 2 runs. The first steel cable 2 always runs within the anti-slip groove, effectively preventing it from accidentally slipping off the guide wheel surface during operation. Preferably, the anti-slip groove has a cross-sectional shape that matches the diameter of the first steel cable 2, and its depth is slightly greater than the radius of the steel cable, effectively limiting lateral displacement or jumping out of the groove during operation.

[0030] Connector 7 is a spring-loaded hook or latch. It facilitates quick and reliable attachment and detachment of the lugs on the vessel lid.

[0031] The lower end of the column 1 is rotatably connected to the base cylinder 9 via a bearing or bushing structure. The base cylinder 9 is a fixed sleeve structure. Preferably, the bottom of the base cylinder 9 is provided with a connecting plate, which is fixed to the ground by anchor bolts. The rotational position of the column 1 relative to the base cylinder 9 can be locked by a fixing component. When it is necessary to adjust the position of the lifted vessel lid, the fixing component can be removed, and the column 1 (along with the entire extraction device and the suspended vessel lid) can be manually rotated around the vertical axis, thereby moving the vessel lid from directly above the vessel body to a safe side position. After adjustment, the fixing component can be tightened again. This design greatly facilitates the relocation of cleaning operation space.

[0032] The lower end of the column 1 is provided with a radial through hole 10, and the wall of the base cylinder 9 is provided with at least two pairs of adjustment holes 11 that mate with the through hole. The fixing member passes through the adjustment hole 11 and the through hole 10. The through hole 10 can be connected to any pair of adjustment holes 11 by the rotation of the column 1. The fixing member is a locking rod 12.

[0033] Preferably, the locking rod 12 includes a rod body, one end of which is provided with a limiting element (for example, a limiting rod welded perpendicular to the rod body, or a limiting ring fixed coaxially with the rod body), and the other end is provided with a threaded section. When it is necessary to fix the column 1, the column 1 is rotated so that the through hole 10 is aligned with a pair of adjustment holes 11 on the base cylinder 9 (for example, 0 degrees, 120 degrees or 240 degrees). The rod body of the locking rod 12 is then passed through the adjustment hole 11 on one side of the base cylinder 9, through the through hole 10 of the column 1, and then through the corresponding adjustment hole 11 on the other side of the base cylinder 9. Then, the nut is tightened on the threaded section at its protruding end so that the nut is pressed against the outer wall of the base cylinder 9. At the same time, the limiting element (limiting rod or limiting ring) at the other end of the locking rod 12 is pressed tightly against the outer wall of the other side of the base cylinder 9. Thus, the column 1 and the base cylinder 9 are firmly fixed relative to each other by the cooperation of the nut and the limiting element, preventing the locking rod 12 from moving and the column 1 from rotating.

[0034] Preferably, there are three pairs of adjustment holes 11, that is, six adjustment holes are provided on the cylinder wall of the base cylinder 9, and the six adjustment holes are distributed around the axial circumference of the base cylinder 9. The diameter of the adjustment holes 11 matches the diameter of the through holes 10, and the three pairs of adjustment holes 11 are distributed at 120-degree intervals on the circumference of the base cylinder 9.

[0035] The working principle of the reaction vessel lid extraction device provided by the utility model is as follows: When in use, the winch 5 is controlled to place the lifting plate 6 at a suitable height, the connector 7 on the second steel cable 4 is connected to the lug on the reaction vessel lid, and then the winch 5 is started to wind up. The lifting plate 6 rises and drives the lid to rise together. The column 1 can also be rotated by adjusting the locking rod 12, so that the lifted lid can be removed from the top of the vessel body, which is convenient for cleaning.
