Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, specifically to a molecular sieve barrel vibration filling device. Background Technology

[0002] Molecular sieve barrel vibration filling equipment is an automated filling equipment that uses vibration to uniformly fill molecular sieves into barrel-shaped containers.

[0003] In existing molecular sieve barrel vibratory filling equipment, the vibration generated during the vibratory feeding process inevitably spreads to the surrounding area. This phenomenon not only interferes with the normal operation of other components of the equipment, but also significantly reduces their service life over time. Taking existing equipment as an example, such as some oxygen production equipment, the vibration of the air compressor during operation is transmitted through the steel structure base, causing resonance of the molecular sieve in the adsorption tower. This not only affects the structural stability of the molecular sieve, causing adsorbent particles to move and wear, shortening the service life of the molecular sieve, but also increases maintenance and repair costs. Furthermore, there is generally a lack of effective buffering mechanisms when positioning the filling barrel. To achieve uniform filling of the molecular sieve inside the filling barrel, existing equipment uses the method of contact between the filling barrel and the vibrating component, using vibration to fully disperse the molecular sieve particles inside the filling barrel. The vibration generated by the vibrating component is transmitted to the positioning component through the filling barrel. Under prolonged contact, the positioning component will deform. The deformation of the positioning component causes the positioning center of the filling barrel to deviate from the vibration center of the vibrating component, affecting the filling accuracy.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a molecular sieve barrel vibration filling device.

[0026] This utility model provides, for example Figure 1-3 The molecular sieve barrel vibrating filling equipment shown includes a base 1, with brackets 2 fixedly connected to the top two ends of the base 1 via a buffer mechanism, a protective shell 3 fixedly connected between the two brackets 2, a weighing valve 4 fixedly connected inside the cavity of the protective shell 3, a suction pump 5 fixedly connected to the top of the protective shell 3, the bottom of the suction pump 5 passing through the top of the protective shell 3 and fixedly connected to the top of the weighing valve 4, a molecular sieve barrel 6 fixedly connected to the top of the suction pump 5, a vibrating feeding conduit 7 fixedly connected to the bottom of the protective shell 3, and the bottom output end of the weighing valve 4 fixedly connected to the input end of the vibrating feeding conduit 7.

[0027] Flexible positioning clamping plates 8 are fixedly connected to the side walls of both ends of the base 1 via the clamping mechanism. A support plate 9 is fixedly connected to the side wall of the base 1. A buffer seat device 10 is fixedly connected to the top of the support plate 9. A connecting chamber 11 is fixedly connected to the top of the buffer seat device 10. Multiple spring hydraulic buffers 12 are fixedly connected between the connecting chamber 11 and the support plate 9. A vertical vibrator 13 is fixedly connected inside the cavity of the connecting chamber 11. A placement platform 14 is fixedly connected to the top vibrating end of the vertical vibrator 13. The buffer mechanism reduces the transmission of vibration to the base 1 and surrounding components, extends the service life of the equipment, and reduces maintenance costs. The protective shell 3 protects the internal components such as the weighing valve 4. The suction pump 5 transports the material in the molecular sieve bucket 6 to the weighing valve 4 to achieve quantitative feeding. The vibrating feeding guide 7... Vibration-assisted feeding improves feeding efficiency. The weighing valve 4, combined with a common component consisting of an electric valve device and a weighing sensor, ensures accurate filling volume. The clamping mechanism drives the flexible positioning clamp 8 to stably position the molecular sieve barrel, preventing barrel displacement due to vibration and ensuring filling accuracy. The buffer seat device 10 and spring hydraulic buffer 12 work together to absorb the vibration generated by the vertical vibrator 13, reducing vibration transmission and protecting equipment components. The vertical vibrator 13 drives the placement platform 14 to vibrate, which helps the material to compact inside the barrel and improves filling quality. This solves the problems of existing molecular sieve barrel vibration filling equipment where vibration is transmitted to the surrounding area during vibration feeding, leading to shortened equipment component life and increased maintenance costs, and the reduction in filling accuracy caused by vibration deformation of the positioning component.

[0028] To achieve cushioning and shock absorption for the filling equipment, such as Figure 1 and 2As shown, the buffer mechanism includes a friction support plate 15, a polyurethane support column 16, and an air spring damper 17. The bottom of the two end supports 2 are fixedly connected to the friction support plate 15, and the top of the two end supports 1 are fixedly connected to the polyurethane support column 16. The top of the two end polyurethane support column 16 is fixedly connected to the bottom of the friction support plate 15. Multiple air spring dampers 17 are fixedly connected between the top of the two end supports 1 and the bottom of the two end supports 2. The polyurethane support column 16 has good elasticity and buffering performance, which can initially absorb vibration. The air spring damper 17 can further attenuate vibration. The two work together to significantly reduce the transmission of vibration to the base 1. The friction support plate 15 increases the friction with the polyurethane support column 16, ensuring connection stability and extending the service life of equipment components.

[0029] In order to clamp and position the filling barrel, such as Figure 1-3 As shown, the clamping mechanism includes a bidirectional screw 18, a motor 19, a threaded sleeve 20, and a sliding opening 21. The bidirectional screw 18 is rotatably connected inside the cavity of the base 1, and the motor 19 is fixedly connected to one end of the cavity of the base 1. One end of the motor 19 is fixedly connected to one end of the bidirectional screw 18. The two ends of the bidirectional screw 18 are threadedly connected to the threaded sleeve 20. Sliding openings 21 are provided at both ends of the side wall of the base 1. One end of the flexible positioning clamp 8 at both ends passes through the corresponding sliding opening 21 and is fixedly connected to the side wall of the corresponding threaded sleeve 20. The motor 19 drives the bidirectional screw 18 to rotate, causing the threaded sleeves 20 at both ends to move in the opposite direction along the sliding opening 21, thereby driving the flexible positioning clamp 8 to move closer or further away synchronously, realizing the stable clamping of molecular sieve barrels of different diameters. The flexible material avoids damage to the barrel body, ensures positioning accuracy, and prevents displacement due to vibration from affecting filling.

[0030] To facilitate material feeding via vibration, such as Figure 1 and 2 As shown, the vibrating feeding conduit 7 includes an inclined feeding conduit 22, with a universal tube head 23 fixedly connected to the output end of the inclined feeding conduit 22. A ring vibrator 24 is fixedly connected to one end of the inclined feeding conduit 22. The inclined feeding conduit 22 facilitates the material to slide down by gravity. The vibration generated by the ring vibrator 24 can prevent material blockage and accelerate feeding. The universal tube head 23 can flexibly adjust the feeding direction to adapt to different filling positions, thereby improving the adaptability and feeding efficiency of the equipment.

[0031] In order for the buffer seat device 10 to achieve a buffering effect, such as Figure 1 and 2As shown, the buffer seat device 10 includes a polyurethane buffer seat 25, and a friction sleeve 26 is slidably frictionally connected to the outer wall of the polyurethane buffer seat 25. The tops of both the polyurethane buffer seat 25 and the friction sleeve 26 are fixedly connected to the bottom of the connecting chamber 11. The polyurethane buffer seat 25 has good elasticity and buffering performance, which can absorb part of the vibration generated by the vertical vibrator 13. The sliding friction between the friction sleeve 26 and the polyurethane buffer seat 25 can further attenuate the vibration energy, reduce the transmission of vibration to the support plate 9, and protect the equipment structure.

[0032] To enhance friction, prevent the bucket from sliding, and avoid damage to the bucket during clamping, such as Figure 1 and 2 As shown, the flexible positioning clamps 8 at both ends are plates with arc-shaped openings on their inner walls, and rubber buffer pads 27 are fixedly connected to the inner arc-shaped surfaces. The arc-shaped openings can better fit the outer wall of the molecular sieve barrel, improving clamping stability. The rubber buffer pads 27 are elastic, which can enhance friction to prevent the barrel from sliding and avoid damage to the barrel during clamping, ensuring the stability of the filling process.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
