Description

Technical Field

[0001] This utility model relates to the field of experimental equipment for polymer materials, and in particular to a spraying device for SAP experiments that can be adjusted at multiple angles. Background Technology

[0002] In the research and development and performance improvement experiments of superabsorbent polymers (SAP), it is often necessary to spray solutions of crosslinking agents and hydrophobic modifiers onto their surface to study their effects on properties such as SAP liquid absorption rate and gel strength. Currently, the spraying equipment commonly used in laboratories usually consists of a liquid storage tank, a pneumatic spray gun, and a simple vertical support. The spray gun is fixed to the upright of the support by a clamp, and its height can only be adjusted in the vertical direction.

[0003] This spraying device has obvious drawbacks: the spraying angle is fixed and the flexibility is poor. The spray gun can only spray vertically downwards and cannot adjust the spraying angle according to experimental needs (such as simulating different spraying angles, treating the inner wall of a container of a specific shape, or SAP samples in a specific area), which seriously affects the diversity and accuracy of the experiment.

[0004] Easy to clog and corrode: The reagents used in SAP processing are often corrosive or easily solidify and clog the nozzles. Ordinary metal or plastic adjustment parts are easily corroded or have reagent residues condensed when in contact with such reagents for a long time, which can lead to equipment failure and difficulty in cleaning, affecting the reliability of experimental results and increasing maintenance costs.

[0005] Therefore, there is a need for a dedicated experimental spraying device that can provide flexible spraying angles and is corrosion-resistant and non-adhesive. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] This utility model provides a multi-angle adjustable SAP experimental spraying device, including a base connector 1, an adjusting member 2, a height locking member 3, a guide rod 4, and a nozzle. The base connector 1 is movably connected to the adjusting member 2, and the adjusting member 2 can rotate relative to the base connector 1. The guide rod 4 passes through the adjusting member 2 and can slide relative to the adjusting member 2. The height locking member 3 is threadedly connected to the adjusting member 2, and the end of the height locking member 3 can abut against the side wall of the guide rod 4. The end of the guide rod 4 is connected to the nozzle. The base connector 1 is used to install at the top opening of the container. This utility model provides a multi-angle adjustable SAP experimental spraying device. In use, by placing the base connector 1 at the top opening of the container, the nozzle is located inside the container. Due to the connection between the base connector 1 and the adjusting component 2, the operator can operate by holding the guide rod 4, which allows the nozzle to perform a wide range of pitch, rotation, and other multi-angle attitude adjustments in three-dimensional space. By adjusting the tightness of the height locking component 3, the position of the nozzle in the height direction can be adjusted, which greatly meets the needs of different experimental scenarios for spraying orientation and angle, significantly improves the versatility of the device and the flexibility of experimental design, enriches experimental methods, and improves the comprehensiveness of experimental data.

[0025] As an optional implementation, the adjusting member 2 is provided with a through channel and a threaded hole. The length direction of the through channel is consistent with the length direction of the adjusting member 2. The through channel and the threaded hole are perpendicular to each other and connected. The guide rod 4 passes through the through channel and can move relative to the through channel. The height locking member 3 is threadedly connected to the threaded hole. When the end of the height locking member 3 abuts against the side wall of the guide rod 4, the guide rod 4 is restricted and cannot move relative to the through channel, so the height of the nozzle cannot be adjusted. When the end of the height locking member 3 does not contact the side wall of the guide rod 4, the restriction on the guide rod 4 is released, and it can move relative to the through channel. At this time, the height of the nozzle can be adjusted.

[0026] As an optional implementation, the adjusting member 2 includes a ball head 21 and a sleeve portion 22, which are fixedly connected. The ball head 21 and the sleeve portion 22 are internally connected to form a through channel. A threaded hole is provided on the side wall of the sleeve portion 22. The ball head 21 is movably connected to the base connector 1. The structure of the ball head 21 is part of a ball, which facilitates universal rotation with the base connector 1.

[0027] As an optional implementation, the base connector 1 includes a universal sleeve 11, a locking sleeve 12, and an adjusting screw 13. The ends of the locking sleeve 12 and the universal sleeve 11 are connected by the adjusting screw 13, and the adjusting screw 13 can change the distance between the locking sleeve 12 and the universal sleeve 11. The universal sleeve 11 and the locking sleeve 12 are fitted onto the ball head 21. By adjusting the distance between the locking sleeve 12 and the universal sleeve 11, the tightness of the universal sleeve 11 and the locking sleeve 12 on the ball head 21 can be adjusted, thereby changing the sensitivity of the ball head 21.

[0028] As an optional implementation, the inner wall of the universal sleeve 11 is set with an arc-shaped structure, and the inner wall of the locking sleeve 12 is set with an arc-shaped structure in order to adapt to the ball head 21.

[0029] As an optional implementation, the other end of the universal sleeve 11 is provided with a limiting end ring 111, which is for docking with the top opening of the container.

[0030] As an optional implementation, the height locking component 3 includes a butterfly handle and a threaded post. The butterfly handle and the threaded post are fixedly connected, and the threaded post is threadedly connected to a threaded hole. The butterfly handle is for the operator to easily rotate the height locking component 3. The height locking component 3 is used to reliably lock the linear positioning, and the adjusting screw 13 is used to reliably lock the angle and attitude. This ensures that after the position and attitude are adjusted, accidental displacement during the spraying process is avoided, guaranteeing the stability and repeatability of the operation. The overall structure is compact, and the adjustment and locking operations are intuitive and convenient.

[0031] As an optional implementation, the base connector 1, adjusting component 2, guide rod 4, and nozzle are all made of polytetrafluoroethylene (PTFE). PTFE is known for its excellent chemical inertness, resistance to strong acids and alkalis, and extremely low surface energy (non-stickiness). This effectively avoids corrosion and residual clogging of the apparatus by experimental reagents, effectively prevents adjustment failures caused by corrosion and experimental errors caused by residue contamination, ensures the stability of the spraying process and the accuracy of experimental results, and also makes the apparatus easier to clean and maintain, resulting in a longer service life.

[0032] As an optional implementation, the system also includes a storage tank, a pump body, and a connecting conduit. One end of the connecting conduit is connected to the storage tank, and the other end is connected to the other end of the guide rod 4. The pump body is connected to the connecting conduit, and the inner wall of the guide rod 4 is provided with a liquid guiding channel. The solution in the storage tank, under the action of the pump body, passes through the connecting conduit and the liquid guiding channel in sequence, and is then sprayed out from the nozzle.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
