[0037] Reference Figures 1-4 For the first embodiment of the utility model, a pressure relief device for feeding a spin dryer is proposed, which is used to balance the pressure of the vacuum pump 1 feeding into the container 2, including the frame body 3 having the first placement layer 31 and the second placement layer 32, the first placement layer 31 is located above the second placement layer 32, the second placement layer 32 has the through port 321, the through port 321 is used to lead to the container 2; the feeding cylinder 4 is arranged on the second placement layer 32, one end of which is in communication with the through port 321, and the other end has a pressure relief port 401, the side wall of the feeding cylinder 4 has a feeding port 402; one end of the feeding pipe 5 is used to communicate with the vacuum pump 1, and the other end is tangentially arranged on the side wall of the feeding cylinder 4 and communicates with the feeding port 402.
[0038] In this embodiment, the feeding cylinder 4 is placed on the second placement layer 32, one end of which is seamlessly connected with the through port 321, which ensures that the material can smoothly enter the container 2 from the through port 321. The end connected with the feeding port 402 of the feeding pipe 5 is tangential to the feeding cylinder 4. In the process of raw material entering the container 2, after the vacuum pump 1 is started, the material enters the feeding cylinder 4 along the tangential direction from the feeding pipe 5, forming a rotating flow in the feeding cylinder 4, so that the gas in the container 2 can be discharged through the pressure relief port 401 in the middle of the feeding cylinder 4 at the same time of feeding, and the rotating movement of the material also has a certain suction effect on the gas in the container 2, accelerating the discharge of the gas during feeding, so that the material can be fed into the container 2 more uniformly, and it is also beneficial to the preliminary balance of pressure and reduce the possibility of sudden increase of local pressure.
[0039] Furthermore, the feed cylinder 4 is cylindrical, and the pressure relief port 401 is coaxially arranged with the feed cylinder 4.
[0040] In this embodiment, the cylindrical feed cylinder 4 facilitates smoother material flow within it, and the coaxially arranged pressure relief port 401 allows for uniform release of gas from the container 2. When conveying material into the ton bag, if an abnormal pressure increase occurs, the pressure will be discharged outwards along the pressure relief port 401, which is coaxial with the feed cylinder 4, without significantly interfering with the material flow direction, thus ensuring stable feeding. This avoids material flow disturbances caused by pressure relief, improving the reliability of the feeding process and the quality of material delivery.
[0041] Furthermore, the feed inlet 402 is located at the end of the feed cylinder 4 near the pressure relief port 401.
[0042] In this embodiment, when the vacuum pump 1 feeds the material into the feed cylinder 4 through the feed pipe 5, because the feed port 402 is close to the pressure relief port 401, the swirling path formed after the material enters the feed cylinder 4 is longer. This allows time for the gas in the container 2 to be discharged through the pressure relief port 401, and also provides stronger swirling suction for the gas in the container 2. Furthermore, it reduces the probability of material accumulating at the outlet 321, effectively avoiding material blockage during feeding.
[0043] Furthermore, it also includes a filter 6, which is used to install at the feed end of the vacuum pump 1, and the material enters the vacuum pump 1 after being filtered by the filter 6.
[0044] In this embodiment, filter 6 is installed at the feed end of vacuum pump 1. When vacuum pump 1 draws material, it first passes through filter 6. Filter 6 can adopt a metal mesh structure, which can effectively filter out impurities, dust and some small unqualified particles in the material, prevent these impurities from entering vacuum pump 1, ensure the normal operation of vacuum pump 1, avoid impurities from causing wear or blockage to the internal structure of vacuum pump 1, and at the same time improve the quality of material supply.
[0045] Furthermore, it also includes an air guide pipe 7, which is located at the end of the feed cylinder 4 away from the second placement layer 32. One end of the air guide pipe 7 is located outside the feed cylinder 4, and the other end is located inside the feed cylinder 4 and its height is lower than the feed inlet 402. The inner cavity of the air guide pipe 7 is a pressure relief port 401.
[0046] In this embodiment, when the pressure inside container 2 increases during the feeding process, the gas can be discharged through the inner cavity of the air guide pipe 7 to relieve pressure. Since the end of the air guide pipe 7 located inside the feed cylinder 4 is lower than the feed inlet 402, it can prevent the high-speed flowing material from disturbing and impacting the airflow in the middle of the feed cylinder 4 during the material entering the feed cylinder 4, thereby making the pressure relief process more stable and the suction force generated by the swirling material has a better adsorption effect on the gas inside container 2.
[0047] Further, the air guide pipe 7 has a plurality of nozzles 701 located in the feeding cylinder 4, and the plurality of nozzles 701 are distributed along the circumferential wall of the air guide pipe 7.
[0048] In this embodiment, when the type of the material to be supplied changes, the feeding pipe 5 of the feeding cylinder 4 needs to be cleaned to avoid mixing of different materials. At this time, the water can be sent into the feeding pipe 5 and the feeding cylinder 4 through the vacuum pump 1 for flushing, but since the feeding port 402 is located on the upper side of the side wall of the feeding cylinder 4, the water vortex cannot completely flush the feeding cylinder 4, so a plurality of nozzles 701 are arranged at one end of the air guide pipe 7. After the water is sprayed into the feeding cylinder 4 from the air guide pipe 7, the water is uniformly sprayed from the plurality of nozzles, which can continuously flush the inner wall of the feeding cylinder 4.
[0049] Further, the air guide pipe 7 is arranged on the feeding cylinder 4 in a lifting manner, and further comprises an adjusting member 8 arranged at both ends of the air guide pipe 7 and the feeding cylinder 4, respectively. The adjusting member 8 is used to adjust the height of the air guide pipe 7.
[0050] In this embodiment, through the adjusting member 8, the length of the air guide pipe 7 entering the feeding cylinder 4 can be adjusted according to different feeding requirements and material characteristics, so as to change the relative position relationship between the pressure relief port 401 and the feeding port 402, thereby optimizing the pressure regulation effect. The lifting arrangement of the air guide pipe 7 and the cooperation of the adjusting member 8 make the pressure relief device adapt to the changes of different materials and feeding conditions, improve the flexibility and universality of the device, and achieve a relatively ideal pressure regulation effect in different production scenes, thereby improving the stability and reliability of the pressure relief device. During the cleaning process of the feeding cylinder 4, the position of the air guide pipe 7 can also be adjusted to adjust the height of the nozzles 701, so that the feeding cylinder 4 can be better cleaned.
[0051] Further, the feeding cylinder 4 comprises a first cylinder body 41 arranged on the second placing layer 32, and the side wall of the first cylinder body 41 has a first inlet 411; a second cylinder body 42 is detachably arranged in the second cylinder body 42, and the side wall of the second cylinder body 42 has a second inlet 421. The first inlet 411 and the second inlet 421 constitute the feeding port 402, and the air guide pipe 7 is arranged on the second cylinder body 42.
[0052] In the embodiment, the feeding cylinder 4 is composed of a first cylinder body 41 and a second cylinder body 42. When feeding, the material enters the feeding cylinder 4 from the feeding pipe 5 through the first inlet 411 and the second inlet 421. When it is necessary to check or clean the inside of the feeding cylinder 4, the second cylinder body 42 can be conveniently disassembled, for example, after changing different materials, the residual materials can be conveniently cleaned. The split structure of the feeding cylinder 4 facilitates the maintenance and cleaning of the equipment, improves the operability and hygiene of the equipment, can effectively avoid cross contamination between different batches of materials, ensures the quality stability of the products, and facilitates the checking and replacement of the internal components of the feeding cylinder 4, and reduces the equipment maintenance cost.
[0053] Further, the side wall of the first cylinder body 41 further has a third inlet 412, and the second cylinder body 42 is rotatably arranged in the first cylinder body 41. After the second cylinder body 42 is rotated, the second inlet 421 is in communication with the first inlet 411 or the third inlet 412, and the third inlet 412 is used for connecting a cleaning water pipe.
[0054] In the embodiment, the side wall of the first cylinder body 41 further has a third inlet 412, and the second cylinder body 42 is rotatably arranged in the first cylinder body 41. When feeding, the first inlet 411 and the second inlet 421 are in communication to form a feeding port 402; when cleaning the feeding cylinder 4, the second cylinder body 42 is rotated to make the second inlet 421 in communication with the third inlet 412, and then a cleaning water pipe is connected to the third inlet 412, so that the inside of the feeding cylinder 4 can be completely cleaned. The design of the third inlet 412 and the rotating structure of the second cylinder body 42 further improves the cleaning function of the feeding cylinder 4, can realize more comprehensive and thorough cleaning effect, effectively avoids the quality problems and safety hazards caused by material residues, and has important significance for some industries with extremely high requirements on purity and safety. Through the design of the third inlet 412, the cleaning of the feeding cylinder 4 is more flexible and convenient, and the cleaning efficiency is better.
[0055] Further, the first flange 9 is arranged on the first cylinder body 41, and the second flange 10 is arranged on the second cylinder body 42, and the second flange 10 has a plurality of long hole 101, the long hole 101 is arc-shaped, and the long hole 101 is used for connecting with the first flange 9.
[0056] In the embodiment, the first cylinder body 41 and the second cylinder body 42 are installed together through the first flange 9 and the second flange 10. When the second cylinder body 42 is installed to the first cylinder body 41, the long hole 101 is connected with the first flange 9, so that the installation angle of the second cylinder body 42 can be conveniently adjusted, thereby adjusting the relative position relationship between the second inlet 421 and the first inlet 411 and the third inlet 412, adapting to the feeding or cleaning requirements. The assembly flexibility of the equipment is improved, which is helpful to improve the working efficiency and adaptability of the whole spin dryer feeding system.
