Description

Technical Field

[0001] This application relates to a simple foaming experiment auxiliary device, belonging to the technical field of foaming experiment auxiliary devices. Background Technology

[0002] The research and development of foamed materials is relatively mature. The research and development of new foamed materials often requires going through the experimental stage, the pilot stage, and the intermediate stage before mass production can be carried out. The experimental stage is the most important part of the research and development work.

[0003] Currently, physical blowing agents are used in all foamed materials. The most widely used are low-boiling-point liquid physical blowing agents, such as pentane and 245Fa. These are added to the raw materials during production, and the gas generated by their volatilization creates a closed-cell structure within the material, thus producing the foamed material. Due to their stable and excellent performance, they are widely used in polyurethane foamed materials. However, their disadvantage is their low boiling point. In laboratory experiments, disposable beakers are often used for mixing the raw materials. During mixing, gas evaporates from the opening of the disposable beaker, causing some gas to escape and making it difficult to form a closed-cell structure within the material. Furthermore, this escaped gas cannot be measured. Therefore, even if the amount of blowing agent added is precisely controlled in the experimental stage, the impact of the gas generated by the blowing agent on the closed-cell structure within the material is uncontrollable, making it difficult to correlate laboratory results with results from mass production applications.

[0004] Currently, there are specialized foaming machines available for polyurethane foam materials. However, these machines are quite large, requiring a significant amount of raw materials and foaming agent for each experiment, making them unsuitable for small-scale laboratory experiments. Producing a small foaming machine based on its structure requires custom manufacturing from a specific manufacturer, which is not only expensive but also presents challenges due to the often sticky nature of the foam material. Furthermore, the smaller foaming chamber of a small foaming machine makes cleaning difficult.

[0005] Therefore, there is currently a lack of foaming auxiliary devices for small-scale experiments in the laboratory stage. Utility Model Content

[0029] refer to Figure 1-5 This application discloses a simplified foaming experiment auxiliary device, comprising: The cup body 10 has an internal cavity 11 for accommodating a disposable beaker 30. The top of the cup body 10 is fixedly provided with a mouth, and the outer wall of the mouth is provided with external threads. The cup lid 20 is detachably mounted on the cup body 10. The inner wall of the cup lid 20 is provided with an internal thread that mates with the external thread, and the cup lid 20 is provided with a sealing groove 21 that abuts against the cup mouth. Figure 1 (Not shown in the image) A sealing gasket is fixed inside the sealing groove 21. The cup lid 20 is provided with a pressure relief port 22, a raw material inlet 23, a stirring paddle opening 24, a foaming agent inlet 25, and a vacuum port 26. The raw material inlet 23 is connected to the raw material inlet pipe 41. The stirring paddle opening 24 is arranged on the same central axis as the cup lid 20. The foaming agent inlet 25 is connected to the foaming agent inlet pipe 51. The vacuum port 26 is connected to the vacuum mechanism. Both the cup body 10 and the cup lid 20 are made of transparent material.

[0030] This device is a simple auxiliary device that applies the structure of the cup body 10 and the cup lid 20 to the experimental stage. Utilizing the sealing properties of the cup body 10 and the cup lid 20, a disposable beaker 30 is placed inside the receiving cavity 11 and covered by the cup lid 20. Therefore, the disposable beaker 30 can be placed in a sealed environment, which can prevent the leakage of gas generated by the foaming agent. Thus, the amount of gas entering the foaming material can be precisely controlled, thereby improving the accuracy of the experimental stage and making the laboratory results correspond to the production line application results, which is convenient for promoting the transition from the experimental stage to mass production.

[0031] The cup body 10 and the cup lid 20 are connected by internal and external threads, enabling quick opening and closing of the cup body 10 and the cup lid 20, thus improving the ease of use of the device. The sealing groove 21 on the cup lid 20 improves the sealing performance of the device, preventing gas from escaping from the connection between the cup body 10 and the cup lid 20. The raw material inlet 23 on the cup lid 20 facilitates the entry of raw materials into the disposable beaker 30. The stirring paddle opening 24 facilitates the placement of the stirring head of the stirring paddle inside the disposable beaker 30. The stirring rod passes through the stirring paddle opening 24 and connects to the stirring mechanism. The foaming agent inlet 25 facilitates the entry of the foaming agent. The exhaust port 26 not only removes impurities from the gas inside the device, improving the cleanliness of the reaction, but also removes excess gas in time under high pressure, improving the operational safety of the device.

[0032] The transparent material of both the cup body 10 and the cup itself improves operational visibility, allowing operators to observe the reaction within the disposable beaker 30 in a timely manner and understand the reaction progress of the foaming material.

[0033] Specifically, the materials of the cup body 10 and the cup lid 20 can be selected according to actual needs. For example, they can be made of PE, PC, or PET. When made of the above materials, as long as the cup body 10 and the cup lid 20 are undamaged and uncracked, they can be reused repeatedly, reducing the cost of using the device.

[0034] Specifically, the dimensions of the cup body 10 and the lid 20 are determined based on the dimensions of the disposable beaker 30 used, ensuring that when the disposable beaker 30 is placed in the receiving cavity 11, the distance between the top opening of the disposable beaker 30 and the mouth of the beaker does not exceed 5 cm, and the gap between the outer wall of the disposable beaker 30 and the receiving cavity 11 does not exceed 0.5 cm. This design stabilizes the disposable beaker 30 and prevents material spillage. In actual production, the dimensions of the cup body 10 and the lid 20 can be determined based on the existing dimensions of the disposable beaker 30. Each size of disposable beaker 30 corresponds to a specific size of this device.

[0035] Specifically, since the disposable beaker 30 is placed in the receiving cavity 11, the shape of the cup body 10 is adapted to the shape of the disposable beaker 30. When the disposable beaker 30 is cylindrical, the cup body 10 is also cylindrical; when the disposable beaker 30 is an inverted frustum shape, the cup body 10 is also an inverted frustum shape.

[0036] In one implementation, the raw material inlet 23 and the foaming agent inlet 25 are respectively located on both sides of the agitator opening 24, and the air extraction port 26 is located on the same side as the raw material inlet 23.

[0037] This configuration separates the raw material inlet 23 and the foaming agent inlet 25, allowing for selection of whether to simultaneously add raw material inlet 23 and foaming agent inlet 25 as needed. This avoids pre-mixing of the raw material and foaming agent when they are introduced simultaneously, which could affect the foaming process. Furthermore, this configuration facilitates the molding of the cup lid 20, improving the production convenience of the device.

[0038] In one implementation, a raw material inlet pipe 41 is provided with a raw material switching valve 42, and the distance between the raw material switching valve 42 and the raw material inlet 23 is 5-10cm. A foaming agent inlet pipe 51 is provided with a foaming agent switching valve 52, and the distance between the foaming agent switching valve 52 and the foaming agent inlet 25 is 2-5cm.

[0039] By installing a raw material inlet valve 42 on the raw material inlet pipe 41 and a foaming agent inlet valve 52 on the foaming agent inlet pipe 51, the amount of raw material and foaming agent added can be precisely controlled, thereby further improving the accuracy of the experiment. The location of the raw material inlet valve 42 is convenient for operators and allows for precise calculation of the amount of raw material from the raw material inlet valve 42 to the raw material inlet 23, making the raw material usage controllable. Similarly, the location of the foaming agent inlet valve 52 also facilitates operation and precise control of the amount of foaming agent used.

[0040] Specifically, the raw material inlet pipe 41 is connected to the raw material inlet 23. This connection can be a threaded connection, a snap-fit ​​connection, or a connection using an additional elastic sealing plug. When a snap-fit ​​connection is used, the outer wall of the raw material inlet pipe 41 abuts against the inner wall of the raw material inlet 23. When a connection using an elastic sealing plug is used, the elastic sealing plug snaps into the raw material inlet 23 under its elastic force. The sealing plug also has an opening in its center, and the raw material inlet pipe 41 snaps into this opening under the elastic force of the sealing plug, thus ensuring that the gas generated by the foaming agent does not overflow from the raw material inlet 23. Similarly, the connection between the foaming agent inlet pipe 51 and the foaming agent inlet 25 can also be configured as described above.

[0041] Specifically, the negative pressure extraction mechanism and the stirring mechanism are not components of this device, and existing mechanisms in the prior art can be used, which will not be elaborated further.

[0042] As one implementation, there are at least two foaming agent inlets 25.

[0043] Since foaming materials generally contain two or more foaming agents, if the foaming agents are mixed and introduced through a single foaming agent inlet 25, the foaming agent gas will evaporate during the mixing process. Therefore, different foaming agent inlets 25 can be set according to actual needs to meet the actual usage requirements.

[0044] In one embodiment, a first insulating sponge is also provided on the inner wall of the receiving cavity 11. The height of the first insulating sponge is 2 / 3 to 3 / 4 of the height of the cup body 10, and the thickness is 0.5-2cm. A second insulating sponge 13 is also provided at the bottom of the receiving cavity 11. The thickness of the second insulating sponge 13 is 0.5-2cm.

[0045] The placement of the first insulating sponge 12 and the second insulating sponge 13 can improve the heat insulation performance of the receiving cavity 11, maintain the environmental stability of the foaming process of the foamed material, and further improve the accuracy of the experiment. However, from the perspective of ease of use and operation visualization, the first insulating sponge 12 cannot exceed 3 / 4 of the height of the cup body 10, and the thickness of the second insulating sponge 13 cannot exceed 2cm.

[0046] For further reference Figure 2 Currently, some disposable beakers 30 have outward protruding notches on their edges to facilitate the pouring of materials. The thickness and height of the first insulating sponge 12 are designed so that the first insulating sponge 12 can circumferentially abut against the disposable beaker 30 without obstructing the notch from being placed in the receiving cavity 11. Therefore, it also has the function of improving the stability of the disposable beaker 30.

[0047] Specifically, the first insulating sponge 12 and the second insulating sponge 13 can be disposed on the inner wall and bottom of the receiving cavity 11 by means of adhesive bonding.

[0048] Specifically, when the disposable beaker 30 is placed in the receiving cavity 11, the bottom of the disposable beaker 30 is placed on the second insulating sponge 13. The side wall of the disposable beaker 30 can directly abut against the first insulating sponge 12, or there can be a certain gap. When there is a certain gap, the gap does not exceed 0.5cm.

[0049] In one embodiment, the bottom of the cup body 10 is provided with an anti-slip groove, the anti-slip groove contains an anti-slip pad, and the surface of the anti-slip pad is provided with anti-slip texture.

[0050] The anti-slip grooves and anti-slip pads at the bottom of the cup body 10 improve the anti-slip performance of the device and facilitate its stability during stirring.

[0051] The pressure relief port 22 provided on the cup lid 20 can promptly release gas when the device is under excessive pressure, improving the safety of the device. This pressure relief port 22 can be a small orifice without additional sealing components. Because it is a small orifice, it can only release pressure when the gas volume is too large, thus improving the flexibility of the device. However, this design will still allow some gas to leak out within a safe range, making it difficult to further improve the accuracy during the experimental stage.

[0052] To address this issue, as one implementation, the device further includes a safety valve 60 made of an elastic material. The safety valve 60 includes a mounting post 61 and a valve cover 62, with the valve cover 62 disposed on top of the mounting post 61. The cup lid 20 is also provided with a safety valve 60 mounting port 27. The mounting post 61 is installed at the safety valve 60 mounting port 27. The valve cover 62 is located above the pressure relief port 22 and blocks the pressure relief port 22. The valve cover 62 can be deformed by the air pressure inside the cup body 10 to open the pressure relief port 22.

[0053] In this configuration, the safety valve 60 is fixed at the mounting port 27 on the cup lid 20 by the cooperation of the mounting post 61. Furthermore, the valve cover 62 of the safety valve 60 can close to the pressure relief port 22 under gravity, achieving a seal. Only when the gas pressure inside the device reaches a certain level can the gas push the valve cover 62 upwards to open the pressure relief port 22 and release pressure. When the gas pressure inside the device decreases to an insufficient level to push the valve cover 62 upwards, the valve cover 62 falls back down, sealing the pressure relief port 22 again. Therefore, this configuration enables the device to self-depressurize while promptly sealing the pressure relief port 22 within a safe range, further improving experimental accuracy. Moreover, it eliminates the need for manual operation, enhancing the ease of use of the device.

[0054] In one implementation, there are at least two pressure relief ports 22, which are evenly distributed around the mounting port 27 of the safety valve 60.

[0055] The two pressure relief ports 22 can improve the gas discharge efficiency, facilitate rapid pressure reduction, improve the safety of the device, and eliminate safety hazards; at the same time, they can also ensure smooth pressure relief in the event of a failure of one of them.

[0056] refer to Figure 6 , Figure 7 As one implementation, the cup body 10 is also provided with a manual exhaust port 14, and a manual exhaust valve 70 is placed inside the manual exhaust port 14. If the operator observes that a lot of gas is generated, he / she can press the manual exhaust valve 70 to make it move left and right, thereby venting the gas and further improving the ease of use of the device.

[0057] For details, please refer to Figure 7 The manual exhaust valve 70 includes a connecting rod 71 and a first baffle 72 and a second baffle 73 disposed on both sides of the connecting rod 71. The first baffle 72 is located on the outer side of the cup body 10, and the second baffle 73 is located on the inner side of the cup body 10. The connecting rod 71 is disposed inside the manual exhaust port 14. A spring 74 is disposed on the connecting rod 71 on the outer side of the cup body 10. One end of the spring 74 abuts against the outer wall of the cup body 10, and the other end abuts against the first baffle 72. Under the elastic force of the spring 74, the second baffle 73 abuts against the inner wall of the cup body 10.

[0058] When the device does not require venting, the spring 74 causes the second baffle 73 to abut against the inner wall of the cup body 10, so the gas inside the cup body 10 cannot flow out from the manual vent 14. When manual venting is required, the operator can press the first baffle 72 inward, causing the spring 74 to compress, and then the second baffle 73 to move inward, allowing the manual vent 14 to circulate with the receiving cavity 11 of the cup body 10, thereby venting the gas in the receiving cavity 11. When the gas is vented to a level that the operator deems safe, the first baffle 72 is released, and the spring 74 rebounds, causing the second baffle 73 to abut against the inner wall of the cup body 10 again, thus resealing the manual vent 14.

[0059] In this manual exhaust valve 70, the connecting rod 71, the first baffle 72, the second baffle 73, and the spring 74 are detachably connected. Specifically, the connecting rod 71 has external threads at both ends, and the first baffle 72 and the second baffle 73 have connecting holes with internal threads. The spring 74 is simply sleeved on the outside of the connecting rod 71. In use, first connect the connecting rod 71 and the second baffle 73 with threads, then extend the connecting rod 71 outward through the manual exhaust port 14, sleeve the spring 74 on the outside of the connecting rod 71, and finally connect the first baffle 72 and the connecting rod 71 with threads, thus completing the installation of the manual exhaust valve 70 at the manual exhaust port 14.

[0060] Taking polyurethane foam as an example, this illustrates the usage of the device: Preparation stage: During the experimental stage, the accurately weighed white material is placed in a disposable beaker 30, and the stirring head of the stirring paddle is placed in the disposable beaker 30. Then, the disposable beaker 30 is placed in the receiving cavity 11 of the cup body 10, and the cup lid 20 is placed on the cup mouth of the cup body 10. The stirring rod of the stirring paddle passes through the stirring paddle opening 24. The cup body 10 and the cup lid 20 are connected by threads to achieve a seal. The raw material inlet pipe 41 is connected to the raw material inlet 23, the foaming agent inlet 25 is connected to the foaming agent inlet pipe 51, the air extraction port 26 is connected to the vacuum mechanism, and the stirring rod is connected to the stirring mechanism. Experimental Stage: The negative pressure extraction mechanism is activated to remove all gas from the device. The foaming agent valve 52 is opened to allow the foaming agent to enter the disposable beaker 30. Once the required amount of foaming agent is reached, the foaming agent valve 52 is closed. The stirring mechanism is then activated, and the stirring paddle agitates the material in the disposable beaker 30. Next, the raw material valve 42 is opened to allow the black material to enter the disposable beaker 30. Once the required amount of black material is reached, the raw material valve 42 is closed. Stirring continues until the reaction is complete. During this process, the pressure relief port 22 automatically releases pressure.

[0061] Removal stage: After the foaming material is prepared, rotate the lid 20 to separate the lid 20 from the body 10, remove the disposable beaker 30 from the cavity 11, and then put the lid 20 back on the body 10.
