Description

Technical Field

[0002] Water-based PU resin system can be blended or copolymerized with other water-based emulsions, which can reduce costs or obtain more diverse and excellent PU emulsions; water-based PU resin has good film-forming properties, strong adhesion, cold resistance, water resistance, solvent resistance, wear resistance, etc. Its hardness can be adjusted, which broadens the application field of water-based PU resin;

[0003] In the production process, acetone is a commonly used solvent. Since the viscosity of water-based PU increases during the reaction, adding acetone helps to reduce the viscosity, making stirring easier and the reaction more complete. Acetone has a low boiling point, and the acetone in the water-based PU can be removed after synthesis.

[0004] The existing stirring is carried out by using a stirring kettle. As too much gas volatilizes inside the stirring kettle, it needs to be depressurized. However, the existing depressurization method does not take filtering measures, which causes the acetone mixed in the gas to be absorbed by people, causing poisoning problems. For this reason, we propose a stirring kettle for artificial leather with water-based PU primer resin. Utility Model Content

[0024] In this embodiment, the depressurized gas can be filtered and collected by providing a filtering mechanism, thereby preventing leakage and poisoning of personnel.

[0025] Specifically, a piston chamber 141 is provided inside the movable sleeve 14 , a piston 142 is movably sleeved inside the piston chamber 141 , and a top of the piston 142 is fixedly connected to a bottom of the movable rod 12 .

[0026] In this embodiment, by providing the piston chamber 141, the movable rod 12 can be freely extended and contracted, thereby facilitating the delivery of gas.

[0027] Specifically, a pressure relief component is provided inside the injection tube 5; the pressure relief component includes an air delivery cavity 501, a connecting plate 502, a telescopic rod 503, a spring c504, and a guide plate 505. The air delivery cavity 501 is provided inside the injection tube 5, a limiting ring is fixedly installed inside the air delivery cavity 501, the telescopic rod 503 is movably sleeved inside the limiting ring, the outer wall of the limiting ring and the connecting plate 502 are in contact with each other, the spring c504 is wound around the outer wall of the telescopic rod 503, and the guide plate 505 is fixedly installed at the bottom of the telescopic rod 503.

[0028] In this embodiment, by providing a pressure relief member, when the internal air pressure of the stirring tank 1 is too high, it can be discharged through the pressure relief member, thereby ensuring the safety of the stirring tank 1.

[0029] Specifically, exhaust ports 506 are provided on both sides of the top of the telescopic rod 503 , and the exhaust ports 506 are located at the connection of the limiting ring.

[0030] In this embodiment, the exhaust port 506 is provided to transport the gas to the location where work is required.

[0031] Specifically, liquid is stored inside the mixing cylinder 8, and connecting cavities are provided inside the delivery pipe b17 and the delivery pipe a11.

[0032] In this embodiment, by setting the liquid, the delivery tube b17 can inject the gas into the liquid, so that it can be easily contained inside and collected, and the connecting cavity inside the delivery tube a11 is interconnected with the interior of the injection tube 5, and the bottom of the injection tube 5 can be inserted into the interior of the delivery tube a11.

[0033] Specifically, a bearing cavity is provided inside the telescopic rod 503 , and the bearing cavity and the exhaust port 506 are communicated with each other.

[0034] In this embodiment, by providing a bearing cavity, the gas can leak out from the inside of the exhaust port 506 through the bearing cavity, thereby facilitating pressure relief.

[0035] Specifically, a circular opening is formed inside the limiting ring, and the circular opening and the outer wall of the telescopic rod 503 are sleeved with each other.

[0036] In this embodiment, the circular opening is provided so that the telescopic rod 503 can be freely extended and retracted.

[0037] Working principle,

[0038] Step 1: During operation, the internal air pressure of the stirring kettle 1 is too high, causing the gas to enter the interior of the gas delivery chamber 501. Since the interior of the gas delivery chamber 501 is provided with a telescopic rod 503 and a guide plate 505, the gas will enter the interior of the bearing chamber at this time. As the gas density increases, the telescopic rod 503 will be pushed upward. During the pushing process, the spring c504 will be squeezed, and the exhaust ports 506 opened on both sides of the telescopic rod 503 can be exposed from the interior of the limiting ring. At this time, the gas inside the bearing chamber will be discharged from the exhaust ports 506 into the interior of the gas delivery chamber 501. When the air pressure becomes smaller, the squeezing force on the spring c504 disappears. At this time, the spring c504 will reset and pull the telescopic rod 503 back to its original position. When the outer wall of the connecting plate 502 and the limiting ring is in contact with each other, the exhaust port 506 will be located inside the limiting ring, which can play a sealing role and prevent the gas from leaking from the connection.

[0039] Step 2. Before the above steps are performed, the outer wall of the connecting block 6 and the inner thread of the mixing barrel 8 are connected. When connected, the bottom of the injection pipe 5 will be plugged into the inside of the delivery pipe a11, causing 10 to move downward. When the connecting block 6 is completely installed in the mixing barrel 8, the outer wall of the delivery pipe a11 will be flush with the top side of the delivery pipe b17. When the above gas enters the interior of the injection pipe 5, it will be transported into the interior of the delivery pipe b17 through 10, and then transported into the interior of the mixing barrel 8 through the delivery pipe b17 for storage. Bubbles will be generated during storage, and at this time the bubbles will slowly rise from the inside of the liquid, and will be punctured when they touch the pointed tip 16 during the rise, which causes the acetone mixed in the gas to dissolve in the liquid.

[0040] Step three, when disassembling, you only need to rotate the connecting block 6 in the opposite direction so that it can be separated from the inside of the mixing barrel 8. At this time, the downward thrust on 10 disappears, causing the movable rod 12 sleeved on the outer wall of the spring a13 to reset, allowing 10 to move to its original position. At the same time, the connection between the delivery pipe a11 and the delivery pipe b17 will be cancelled, causing the delivery pipe b17 to be located at the bottom of 10 to form a sealed space, thereby ensuring the sealing and facilitating subsequent processing and use.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
