Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a novel device for cyclic sampling. Background Technology

[0002] In the fields of chemical engineering, pharmaceuticals, and materials, the reactor is a core reaction device. The efficiency of material mixing, heat transfer, and gas utilization within the reactor is crucial to the reaction process and product quality. The gas flow circulation device for the reactor mainly introduces compressed gas as a power source to build an efficient gas flow circulation system. This device uses gas pressure to drive the reaction medium to flow in the reactor or circulation pipeline, avoiding the drawbacks of mechanical pumps. For example, in scenarios involving gas oxidation and catalytic reactions, the gas flow circulation device can make the reaction gas evenly distributed, increase the gas-liquid-solid contact area, and improve the reaction rate and conversion rate. Chinese Patent Publication No. (CN207641460U) discloses a reaction vessel that uses airflow for stirring, including a sealing structure, a reaction vessel body, a stirring mechanism, and a gas circulation device. The sealing structure is located at the top of the reaction vessel body and has a chamber inside. The stirring mechanism is rotatably located inside the reaction vessel body. The gas circulation device is located above the reaction vessel body and is connected to the sealing structure and the reaction vessel body respectively, so that the gas circulates within the sealing structure and the reaction vessel body, and drives the stirring mechanism to stir within the reaction vessel body. The aforementioned comparative document effectively solves the problems of material leakage and high maintenance costs associated with traditional pump-driven methods by using compressed gas to drive sample circulation. However, the stirring tubes of this device are usually designed with a fixed angle, which exposes significant limitations in practical applications. On the one hand, the physical properties of different samples, such as viscosity, density, and particle size, vary greatly. The fixed-angle stirring tubes are difficult to adapt to diverse mixing needs. For example, high-viscosity samples require a larger angle stirring tube to enhance the airflow driving force, while low-viscosity samples require a smaller angle to optimize the fluid path. The fixed angle cannot be flexibly adjusted, which can easily lead to uneven sample mixing and low circulation efficiency, thereby affecting the accuracy of sample measurement. In view of this, the present invention solves the above-mentioned technical problems by proposing a novel device for cyclic sampling. Utility Model Content

[0003] To address the shortcomings of the aforementioned background technology, this utility model provides a novel technical solution for a circulating sample testing device. Firstly, the jet angle (upward / downward) of the stirring components can be flexibly adjusted, significantly improving the mixing uniformity and circulation efficiency for samples with varying viscosity, density, and particle size, thereby enhancing testing accuracy. Secondly, the drive gear can slide along the rotation axis to switch meshing with the rack, supporting independent angle adjustment of the two stirring components. This adapts to the need for "simultaneous adjustment of different angles" in complex mixing scenarios (e.g., enhancing shear force on one side and optimizing the circulation path on the other), expanding the device's applicability. Finally, the device employs a "rocker-driven - gear and rack transmission - spring reset and locking" structure, requiring only the rotation of the rocker or the pulling plate for simple operation. The automatic reset and locking design of the locking block and slot prevents angle deviation during operation, ensuring long-term stability.

[0004] This utility model provides the following technical solution: A novel device for circulating sample testing includes a reaction vessel body, a gas circulation assembly, and a stirring assembly. A shell is fixedly connected to the inner cavity of the reaction vessel body. Two racks are slidably connected inside the shell. Multiple adjusting gears are meshed on the surfaces of the two racks. One end of each adjusting gear has a through hole, and the other end of the adjusting gear is connected to the stirring assembly. Two connecting plates are fixedly connected to the top plate of the shell. A rotating shaft is connected to the inner cavity of the two connecting plates. A limit block is fixedly connected to the surface of the rotating shaft. An axially movable drive gear is slidably connected to the rotating shaft, and the drive gear meshes with the racks.

[0005] As a preferred embodiment of this utility model, each of the two racks has a plurality of equally spaced slots on one side. A guide plate is fixedly connected to the top of the housing corresponding to each rack. A connecting post is slidably connected to the inner cavity of the guide plate. A locking block that matches the slot is fixedly connected to one end of the connecting post. A return spring is sleeved on the outer periphery of the connecting post. The two ends of the return spring are respectively connected to the guide plate and the locking block.

[0006] As a preferred technical solution of this utility model, a rocker arm is fixedly connected to one end of the rotating shaft, and the two ends of the drive gear are provided with limiting grooves that slide with the limiting block. The drive gear achieves circumferential limiting and axial sliding connection with the rotating shaft through the limiting block.

[0007] As a preferred embodiment of this utility model, one end of the connecting column extends to the outside of the guide plate and is fixedly connected to a pull plate, the surface of which is provided with anti-slip texture.

[0008] As a preferred embodiment of this utility model, the sliding direction of the two racks is a horizontal straight line, and the inner wall of the housing is provided with a polytetrafluoroethylene wear-resistant pad corresponding to the bottom surface of the rack, and the surface of the wear-resistant pad is in sliding contact with the bottom surface of the rack.

[0009] As a preferred embodiment of this utility model, the two racks are symmetrically staggered, the number of limiting blocks is four, and they are distributed in a circular array. The shape of the locking block is triangular, and its position corresponds to the locking slot.

[0010] As a preferred technical solution of this utility model, the gripping end of the rocker is covered with an anti-slip rubber sleeve, the surface of the rubber sleeve is provided with wavy protrusions, and the rocker is connected to the rotating shaft by a key connection.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention allows for flexible adjustment of the jet angle (upward / downward) of the stirring component, significantly improving the uniformity of sample mixing and circulation efficiency to address differences in viscosity, density, and particle size of different samples, thereby enhancing the accuracy of sample measurement.

[0012] The active gear of this invention can slide and switch the meshing rack along the rotation axis, supporting independent angle adjustment of two sets of stirring components, adapting to the need for "simultaneous adjustment of different angles" in complex mixing scenarios (such as enhancing shear force on one side and optimizing the circulation path on the other side), thus expanding the applicability of the device.

[0013] This utility model adopts a structure of "rocker drive - gear rack transmission - spring reset and locking". The adjustment process only requires rotating the rocker or pulling the pull plate, which is simple to operate. The automatic reset and locking design of the card block and the card slot avoids angle deviation during operation and ensures long-term stability. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-5 As shown, a novel cyclic sampling device includes a reaction vessel body 1, a gas circulation assembly, and a stirring assembly. A shell 2 is fixedly connected to the inner cavity of the reaction vessel body 1. Two racks 201 are slidably connected inside the shell 2. Multiple adjusting gears 202 are meshed on the surfaces of the two racks 201. One end of the adjusting gear 202 has a through hole 203, and the other end of the adjusting gear 202 is connected to the stirring assembly. Two connecting plates 204 are fixedly connected to the top plate of the shell 2. A rotating shaft 205 is connected to the inner cavity of the two connecting plates 204. A limit block 206 is fixedly connected to the surface of the rotating shaft 205. An axially movable drive gear 207 is slidably connected to the rotating shaft 205. The drive gear 207 meshes with the racks 201. Each of the two racks 201 has multiple equally spaced slots 3 on one side. A guide plate 301 is fixedly connected to the top of the housing 2 corresponding to each rack 201. A connecting post 302 is slidably connected to the inner cavity of the guide plate 301. A locking block 303 that matches the slot 3 is fixedly connected to one end of the connecting post 302. A return spring 304 is sleeved on the outer periphery of the connecting post 302. The two ends of the return spring 304 are connected to the guide plate 301 and the locking block 303 respectively. One end of the rotating shaft 205 is fixedly connected to a rocker arm 4, and the two ends of the drive gear 207 are provided with limiting grooves that slide with the limiting block 206. The drive gear 207 achieves circumferential limiting and axial sliding connection with the rotating shaft 205 through the limiting block 206. One end of the connecting column 302 extends to the outside of the guide plate 301 and is fixedly connected to the pull plate 401. The surface of the pull plate 401 is provided with anti-slip texture. Pulling the pull plate 401 can disengage the locking block from the slot 3, releasing the rack 201 from locking and making it easier to adjust the position of the rack 201; the anti-slip texture increases hand friction, making it easy to operate even in wet or gloved environments; The sliding direction of the two racks 201 is a horizontal straight line. The inner wall of the housing 2 is provided with a polytetrafluoroethylene wear-resistant pad corresponding to the bottom surface of the racks 201. The surface of the wear-resistant pad is in sliding contact with the bottom surface of the racks 201. The PTFE wear-resistant pad has self-lubricating properties, which greatly reduces the frictional resistance when the rack 2201 slides, reduces mechanical wear, extends the service life of the device, and reduces energy consumption and noise. The two racks 201 are symmetrically staggered, the number of limit blocks 206 is four, and they are distributed in a ring array. The shape of the locking block 303 is triangular, and its position corresponds to the locking slot 3. The grip end of the joystick 4 is covered with a non-slip rubber sleeve, and the surface of the rubber sleeve has wavy protrusions. The joystick 4 is connected to the rotating shaft 205 by a key connection. The wavy, raised rubber sleeve increases grip friction, reduces hand fatigue, and is especially suitable for long-term manual adjustment scenarios, improving operating comfort. The key connection ensures that the joystick 4 and the rotating shaft 205 rotate synchronously, preventing slippage or loosening and ensuring effective transmission of torque, so that it can work stably even when a large torque is applied.

[0018] Jet angle pitching adjustment process When it is necessary to adjust the jet angle of the stirring component to tilt upwards, the operating steps are as follows: Drive input: Manually rotate the joystick 4, which drives the rotating shaft 205 to rotate synchronously through the transmission connection; Gear transmission: The rotation of the rotating shaft 205 synchronously drives the drive gear 207 fixedly connected to it to rotate, and the drive gear 207 pushes the rack 201 to move upward in the vertical direction through tooth meshing; Angle adjustment: When the rack 201 moves upward, the groove 3 on its surface moves upward and presses the inclined surface of the block 303, forcing the block 303 to retract away from the groove 3 and compress the return spring 304; at the same time, the movement of the rack 201 drives the adjusting gear 202 to rotate through tooth meshing. The adjusting gear 202 is connected to the stirring assembly, thereby driving the stirring assembly to deflect upward around the rotation center, realizing the upward tilting of the jet angle; Automatic locking: When the angle is adjusted to the target position, the rocker arm 4 stops rotating. At this time, the elastic force of the reset spring 304 pushes the locking block 303 to reset and lock into the inner cavity of the slot 3, thus completing the limit locking of the rack 201 and ensuring that the angle of the stirring component is fixed. Dual-unit stirring component switching adjustment Since the device is equipped with two sets of stirring components (corresponding to two sets of racks 201 and adjusting gears 202), when it is necessary to adjust the other set: Gear switching: Manually push the drive gear 207 to slide along the axial direction of the rotating shaft 205 (the drive gear 207 and the rotating shaft 205 are slidably connected to maintain rotational synchronization), so that it disengages from the currently meshing rack 201 and completes gear meshing with another set of racks 201; Repeat adjustment: Follow the above "Jet Angle Upward Adjustment Process" to operate the joystick 4 to adjust the jet angle upward of another set of stirring components; Jet angle pitching adjustment process When it is necessary to adjust the downward angle of the jet nozzle of the stirring component: Release the limit: Manually pull the pull plate 401. The pull plate 401 drives the locking block 303 to move away from the locking groove 3 through the connecting column 302, so that the locking block 303 is completely disengaged from the inner cavity of the locking groove 3 (at this time, the return spring 304 is further compressed). Reverse drive: Rotate the rocker arm 4 (reverse rotation), which drives the drive gear 207 to rotate in the opposite direction through the rotating shaft 205. The drive gear 207 pushes the rack 201 to move downward in the vertical direction. Angle adjustment: When the rack 201 moves downward, it drives the adjusting gear 202 to rotate in the opposite direction through tooth meshing, thereby causing the stirring component to deflect downward around the center of rotation, so as to achieve the downward tilting of the jet angle; Locking Reset: After adjustment, loosen the pull plate 401. The elastic force of the reset spring 304 pushes the locking block 303 to reset and re-lock into the inner cavity of the slot 3, thus completing the angle locking.
