Description

Technical Field

[0001] This utility model relates to the field of material processing technology, and in particular to a pulping kettle. Background Technology

[0002] In the manufacturing process of MHP (metal hydride powder or specific chemical intermediate, the specific name is determined according to the actual product), the raw materials are added to the reaction vessel, stirred and mixed to form a suspension, and then the suspension is extracted for use in subsequent processing steps.

[0003] In existing technologies, the reactors manufactured by MHP are generally cylindrical or similarly shaped sealed containers equipped with internal stirring devices to thoroughly mix the added raw materials. An extraction pipe is installed at a fixed location on the top or side of the reactor, directly connected to the interior. Through an externally connected pump or other power equipment, the suspension inside the reactor is extracted and transported to subsequent processing stages.

[0004] This reactor can only extract suspensions from a fixed height, making it impossible to extract suspensions at different heights according to actual needs. Because the mass of the suspension varies at different heights within the reactor—for example, the upper layer may have finer particles and a relatively uniform concentration due to stirring, while the lower layer may have larger particles and uneven concentration due to gravity settling—a single extraction point cannot obtain suspensions that meet the different quality requirements of subsequent processing. This results in unstable quality of the extracted suspension during subsequent processing, affecting the performance and quality of the final product. Utility Model Content

[0005] The purpose of this invention is to provide a pulping vessel that solves the problem in the prior art where suspensions can only be extracted from a fixed height within the vessel, resulting in significant differences in the quality of the extracted suspensions, making it difficult to meet subsequent processing requirements, and at least reducing the performance and quality of the final product.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a pulping vessel, which includes:

[0008] The vessel body;

[0009] A stirring shaft is rotatably connected to the vessel body;

[0010] A liquid extraction tube is inserted through the vessel body and one end is connected to a liquid extraction device;

[0011] A lifting tube is slidably connected to the other end of the liquid extraction tube;

[0012] A lifting assembly is disposed outside the vessel body and partially extends into the vessel body to connect with the lifting pipe, thereby driving the lifting pipe to slide.

[0013] Optionally, the lifting assembly includes:

[0014] Rollers are rotatably connected to the outside of the vessel body;

[0015] A connecting rope, one end of which is wound around the roller, and the other end extends into the vessel body and is fixedly connected to the lifting pipe;

[0016] A lifting drive unit is fixedly connected to drive the roller to wind up or release the connecting rope.

[0017] Optionally, an arc-shaped connecting block is provided on the side of the lifting pipe near the liquid extraction pipe, and the connecting rope is fixedly connected to the arc-shaped connecting block.

[0018] Optionally, the connecting rope and the roller are provided on both sides of the lifting tube along the radial direction.

[0019] Optionally, each of the rollers is provided with a connecting shaft, and the lifting assembly further includes:

[0020] A drive shaft is connected to the plurality of connecting shafts and to the output end of the lifting drive component.

[0021] Optionally, each of the connecting shafts is provided with a worm gear, and the drive shaft is provided with a worm that meshes with the worm gear at a position corresponding to each worm gear.

[0022] Optionally, a counterweight is provided at the end of the lifting tube away from the connecting rope.

[0023] Optionally, both the counterweight and the lifting tube are provided with a protective layer.

[0024] Optionally, the pulping vessel further includes:

[0025] A detector is configured corresponding to the roller to detect the number of rotations of the roller.

[0026] Optionally, a sealing ring is provided at one end of the liquid extraction tube near the lifting tube, which abuts against the inside of the lifting tube.

[0027] The beneficial effects of this utility model are:

[0028] After the materials and liquids are added to the reactor, the stirring shaft is driven to rotate, thoroughly mixing the materials and liquids to form a suspension. Depending on the mixing conditions, the lifting assembly lowers the lifting pipe to a designated height, immersing its lower end in the required suspension. At this point, the pumping device is activated, extracting the suspension through the pumping pipe and the lifting pipe. The height of the lifting pipe can be further adjusted based on the suspension's quality. Simultaneously, the pumping pipe remains stationary, maintaining a high degree of seal between its upper end and the reactor body. Therefore, during use, this pulping reactor allows for flexible adjustment of the lifting pipe height via the lifting assembly, ensuring the smooth extraction of the required suspension from the reactor, guaranteeing stable suspension quality, meeting the requirements of subsequent processing, and ensuring good performance and quality stability of the final product.

[0039] This utility model embodiment discloses a pulping kettle.

[0040] Reference Figures 1 to 4 The pulping vessel includes a vessel body 1, a stirring shaft 2, a liquid extraction pipe 3, a lifting pipe 4, and a lifting assembly 5. The vessel body 1 is rotatably connected inside the vessel body 1; the liquid extraction pipe 3 passes through the vessel body 1 and one end is connected to a liquid extraction device; the lifting pipe 4 is slidably connected to the other end of the liquid extraction pipe 3; the lifting assembly 5 is located outside the vessel body 1 and partially extends into the vessel body 1 to connect with the lifting pipe 4, so as to drive the lifting pipe 4 to slide.

[0041] Specifically, a lid 11 is provided on the upper side of the vessel body 1, and a feeding port 12 is provided on the lid 11 for adding materials into the vessel body 1. A liquid injection port 13, a first drain port 14, and a second drain port 15 are respectively provided on the side wall of the vessel body 1. The liquid injection port 13 is connected to a liquid injection device to inject liquid into the vessel body 1 to mix with the materials and form a suspension. The first drain port 14 and the second drain port 15 are located at different heights of the vessel body 1 to discharge wastewater at different locations. A stirring shaft 2 passes through the lid 11 and extends into the vessel body 1. A stirring paddle 21 is provided at the lower end of the stirring shaft 2, and the upper end of the stirring shaft 2 is connected to a drive motor.

[0042] A liquid extraction pipe 3 passes through the vessel lid 11 and is sealed to it. The upper end of the liquid extraction pipe 3 is connected to the liquid extraction equipment, and its lower end extends into the vessel body 1. A lifting pipe 4 is slidably connected to the lower end of the liquid extraction pipe 3. The lifting pipe 4 is made of corrosion-resistant material and can be raised and lowered vertically to reach different heights in the vessel body 1. A lifting assembly 5 is mounted on the vessel lid 11, with part of it passing through the lid 11 and extending into the vessel body 1 to connect with the lifting pipe 4. The lifting assembly 5 can use a screw, connecting rod, or rope structure to drive the lifting pipe 4 to rise and fall. The specific design can be tailored to the actual application scenario, and this utility model does not impose any limitations.

[0043] After the materials and liquid are added to the vessel body 1, the stirring shaft 2 is driven to rotate, thoroughly mixing the materials and liquid to form a suspension. Depending on the mixing conditions, the lifting assembly 5 lowers the lifting pipe 4 to a designated height, immersing its lower end in the required suspension. At this point, the extraction device is activated, drawing the suspension out through the extraction pipe 3 and the lifting pipe 4. The height of the lifting pipe 4 can be further adjusted according to the quality of the suspension. Simultaneously, the extraction pipe 3 does not need to be moved, maintaining a high degree of seal between its upper end and the vessel body 1. Therefore, during use, the lifting assembly 5 allows for flexible adjustment of the height of the lifting pipe 4, ensuring the smooth extraction of the required suspension from the vessel body 1, guaranteeing stable suspension quality, meeting the requirements of subsequent processing, and ensuring good performance and quality stability of the final product.

[0044] Optionally, the lifting assembly 5 includes a roller 51, a connecting rope 52, and a lifting drive 53. The roller 51 is rotatably connected to the outside of the vessel body 1; one end of the connecting rope 52 is wound around the roller 51, and the other end extends into the vessel body 1 and is fixedly connected to the lifting tube 4; the lifting drive 53 is fixedly connected to drive the roller 51 to wind up or release the connecting rope 52.

[0045] Specifically, roller 51 is rotatably connected to the vessel lid 11. One end of the connecting rope 52 is fixed to the side wall of roller 51, and part of the connecting rope 52 is wound around roller 51. A winding groove can also be formed on the surface of roller 51 for the connecting rope 52 to be wound. The lifting drive 53 can be a motor or an electric cylinder as the driving element, which can drive roller 51 to rotate forward or reverse, so that the connecting rope 52 is wound around roller 51 or released from roller 51.

[0046] A connection hole is provided on the lid 11. The connecting rope 52 passes through the connection hole and extends into the body 1 and is fixedly connected to the outer wall of the lifting pipe 4. The fixing method can be welding, bonding, snap-fitting or screw connection, etc. This utility model does not limit this.

[0047] When the lifting drive 53 drives the roller 51 to rotate and wind up the connecting rope 52, the connecting rope 52 can pull the lifting tube 4 to rise. When the lifting drive 53 drives the roller 51 to reverse and release the connecting rope 52, the connecting rope 52 loosens, and the lifting tube 4 falls automatically by its own weight, thus smoothly realizing the lifting of the lifting tube 4.

[0048] Optionally, an arc-shaped connecting block 6 is provided on the side of the lifting pipe 4 near the liquid extraction pipe 3, and the connecting rope 52 is fixedly connected to the arc-shaped connecting block 6.

[0049] Specifically, an arc-shaped connecting block 6 is provided on the upper side of the lifting pipe 4. The two can be an integral structure or fixed together by welding or bonding. The arc-shaped connecting block 6 extends circumferentially along the lifting pipe 4, and a connecting notch is provided on the top wall of the arc-shaped connecting block 6. The lower end of the connecting rope 52 is placed in the connecting notch and locked by screws or pressure blocks, so that the connecting rope 52 is fixedly connected to the arc-shaped connecting block 6.

[0050] By setting the arc-shaped connecting block 6, the tension generated by the connecting rope 52 is evenly distributed on the outside of the lifting pipe 4 through the arc-shaped connecting block 6, ensuring the stable lifting of the lifting pipe 4. On the other hand, it also ensures that the connecting rope 52 extends vertically, so that the tension of the connecting rope 52 is generated entirely in the vertical direction, thereby further improving the stability of the lifting pipe 4. Simultaneously, the arc-shaped connecting block 6 is located on the upper side of the lifting pipe 4, keeping the connection point between the connecting rope 52 and the lifting pipe 4 away from the suspension, thus reducing the possibility of the connecting rope 52 directly contacting the suspension and protecting the safety of the connecting rope 52. The connecting rope 52 itself can also be made of corrosion-resistant material, with a coating on its outer surface to further improve its corrosion resistance and strength.

[0051] Optionally, the lifting pipe 4 is provided with connecting ropes 52 and rollers 51 on both sides along the radial direction.

[0052] Specifically, a set of connecting ropes 52 and rollers 51 are respectively set on both sides of the lifting tube 4. Each roller 51 can be equipped with a lifting drive component 53, or one lifting drive component 53 can drive two rollers 51 to rotate. In this way, when the lifting tube 4 is raised or lowered, both sides of the lifting tube 4 can be pulled at the same time to ensure that the lifting tube 4 is subjected to balanced forces during the raising and lowering process.

[0053] Optionally, each roller 51 is provided with a connecting shaft 511, and the lifting assembly 5 also includes a drive shaft 54. The drive shaft 54 ​​is connected to the plurality of connecting shafts 511 and to the output end of the lifting drive 53.

[0054] Specifically, a mounting base is provided on the vessel lid 11, and the connecting shaft 511 is rotatably connected to the mounting base via bearings. The rollers 51 are sleeved on the connecting shaft 511 and fixedly connected to it. The lifting drive component 53 adopts a servo motor, and its output end is fixedly connected to a drive shaft 54 ​​via bearings. The drive shaft 54 ​​can drive multiple connecting shafts 511 to rotate through a gear set or a sprocket chain, thereby driving multiple rollers 51 to rotate synchronously.

[0055] By setting a lifting drive 53 and a drive shaft 54 ​​to drive multiple rollers 51 to rotate, the multiple rollers 51 can rotate synchronously, so that the connecting rope 52 can be wound or released synchronously, thereby ensuring that the connecting rope 52 can move synchronously, and further ensuring that the lifting tube 4 remains stable.

[0056] Optionally, each connecting shaft 511 is provided with a worm gear, and the drive shaft 54 ​​is provided with a worm that meshes with the worm gear at the corresponding part of each worm gear.

[0057] Specifically, the drive shaft 54 ​​is perpendicular to the axis of the connecting shaft 511. A worm gear is fixedly installed on the connecting shaft 511, and a worm is fixedly sleeved on the drive shaft 54. The connecting shaft 511 is driven to rotate by the cooperation of the worm gear and the worm, and the connecting shaft 511 can be automatically locked by the self-locking of the worm gear and the worm.

[0058] Optionally, a counterweight 7 is provided at the end of the lifting tube 4 away from the connecting rope 52.

[0059] Specifically, a counterweight 7 is provided on the lower outer wall of the lifting tube 4. The counterweight 7 can be arc-shaped and extend along the axis of the lifting tube 4. The counterweight 7 can correspond vertically to the arc-shaped connecting block 6 to increase the weight of the lifting tube 4, so that after the connecting rope 52 is released from the roller 51, the lifting tube 4 can descend smoothly under its own weight.

[0060] Optionally, both the counterweight 7 and the lifting tube 4 are provided with a protective layer.

[0061] Specifically, the protective layer is formed by coating the surface of the counterweight 7 and the lifting pipe 4 with a corrosion-resistant material to ensure good overall corrosion resistance and effectively reduce the possibility of the counterweight 7 and the lifting pipe 4 being corroded after entering the suspension.

[0062] Optionally, the pulping vessel also includes a detector. The detector is configured to correspond to the roller 51 to detect the number of rotations of the roller 51.

[0063] Specifically, the detector can be a counting sensor or other sensors. It can be set outside the vessel body 1 and detect the number of rotations of the roller 51. While ensuring the safe operation of the detector, it can also obtain the lifting distance of the lifting pipe 4 in real time, so as to control the lifting pipe 4 to accurately stop at the specified height and extract the suspension that meets the requirements.

[0064] Optionally, a sealing ring 8 is provided at one end of the liquid extraction tube 3 near the lifting tube 4, which abuts against the inside of the lifting tube 4.

[0065] Specifically, a notch is provided at one end of the extraction tube 3 near the lifting tube 4, and a sealing ring 8 is installed in the notch. The sealing ring 8 is made of corrosion-resistant rubber material and protrudes from the notch to abut against the inner wall of the lifting tube 4, thereby sealing the gap between the lifting tube 4 and the extraction tube 3 to smoothly extract the suspension.

[0066] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
