Description

Technical Field

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

[0002] In industrial production and scientific research, molecular sieves, with their uniform microporous structure, play an irreplaceable role in many key processes such as adsorption, separation, and catalysis. Molecular sieve oxygen generators, as common oxygen-generating equipment, have a molecular sieve cylinder filled with molecular sieves as one of their core components. Through their unique physical adsorption and desorption technologies, molecular sieves can efficiently separate oxygen from the air, providing essential oxygen support for people.

[0003] Traditional manual filling methods for molecular sieves have significant limitations. Manual filling is not only labor-intensive and time-consuming, resulting in low efficiency, but also suffers from instability due to the inherent instability of manual operation. It's difficult to precisely control the filling amount and speed, leading to spillage. Spilled molecular sieves not only waste materials and increase production costs but also pollute the working environment, making cleanup extremely difficult. Furthermore, spilled molecular sieves may contaminate other equipment or products, affecting their normal operation and product quality.

[0004] Therefore, it is necessary to modify it by setting a directional filling structure that is compatible with the molecular sieve cylinder, so as to accurately fill the molecular sieve into the molecular sieve cylinder, improve the filling efficiency and filling accuracy of the molecular sieve, and avoid the leakage of molecular sieve during filling, which would cause inconvenience to users.

The top end of the compression spring is fixedly connected to the top of the inner wall of the material box, and the bottom end of the compression spring is fixedly connected to the bottom of the inner wall of the material box. A push ring is fixedly connected to the lower part of the surface of the discharge cylinder. A moving plate is slidably connected to the lower part of the interior of the base. A placement seat is provided above the moving plate. A placement groove is opened on the top of the placement seat. The diameter of the placement groove is slightly larger than the outer diameter of the molecular sieve cylinder. An electric telescopic rod is fixedly connected to the rear side of the inner wall of the base. The output end of the electric telescopic rod is fixedly connected to the top of the moving plate.

[0007] In a preferred embodiment of this utility model, damping retraction rods are fixedly connected to both the left and right sides of the bottom of the placement base.

A vibration motor is fixedly connected to the center of the front side of the top of the moving plate, and the output end of the vibration motor is in contact with the bottom of the placement base.

[0008] As a preferred embodiment of this utility model, the surface of the compression spring is fitted with a retractable rubber sleeve, the top end of the rubber sleeve is fixedly connected to the top of the inner wall of the material box, the bottom end of the rubber sleeve is fixedly connected to the top of the disc, the surface of the discharge cylinder is fitted with a retractable splash guard, the top end of the splash guard is fixedly connected to the bottom of the material box, and the bottom end of the splash guard is fixedly connected to the top of the push ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a stable space for storing molecular sieves by fixing a material box to the top of the base. The top of the material box is hinged to a closed cover via a shaft, facilitating the opening and closing of the material box and the addition of molecular sieves. The sliding connection design between the discharge cylinder and the circular groove at the bottom of the material box allows the discharge cylinder to move flexibly, and its diameter is smaller than the inner diameter of the molecular sieve cylinder, ensuring that the discharge cylinder can be smoothly inserted into the molecular sieve cylinder.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a rapid molecular sieve filling device, including a base 1, a material box 2 fixedly connected to the top of the base 1, a sealing cover 3 hinged to the rear side of the top of the material box 2 via a shaft, a through-hole circular groove at the front bottom of the material box 2, and a discharge cylinder 4 slidably connected inside the groove, the diameter of the discharge cylinder 4 being smaller than the inner diameter of the molecular sieve cylinder, a plurality of evenly distributed through holes located at the bottom of the material box 2 on the surface of the discharge cylinder 4, the diameter of the through holes being larger than the diameter of the molecular sieve, a circular plate 5 fixedly connected to the top of the discharge cylinder 4, the bottom of the circular plate 5 fitting against the bottom of the inner wall of the material box 2, a circular rod 6 fixedly connected to the top of the circular plate 5, the top end of the circular rod 6 penetrating to the top of the material box 2, and a pressure-fitting device on the surface of the circular rod 6. Spring 7, the top end of spring 7 is fixedly connected to the top of the inner wall of material box 2, and the bottom end of spring 7 is fixedly connected to the bottom of the inner wall of material box 2. A push ring 8 is fixedly connected to the lower surface of the discharge cylinder 4. The distance from the top of push ring 8 to the bottom of material box 2 is greater than the distance from the through hole to the inside of material box 2. The diameter of push ring 8 is greater than the outer diameter of molecular sieve cylinder. A moving plate 9 is slidably connected to the lower inside of base 1. A placement seat 10 is provided above the moving plate 9. A placement groove is opened on the top of placement seat 10. The diameter of placement groove is slightly larger than the outer diameter of molecular sieve cylinder. An electric telescopic rod 11 is fixedly connected to the rear side of the inner wall of base 1. The output end of electric telescopic rod 11 is fixedly connected to the top of moving plate 9. Electric telescopic rod 11 is in the extended state.

[0022] refer to Figure 1Damping contraction rods 12 are fixedly connected to the left and right sides of the bottom of the placement seat 10. The bottom end of the damping contraction rod 12 is fixedly connected to the top of the moving plate 9. A stabilizing spring 13 is sleeved on the surface of the damping contraction rod 12. The top end of the stabilizing spring 13 is fixedly connected to the bottom of the placement seat 10. The bottom end of the stabilizing spring 13 is fixedly connected to the top of the moving plate 9. A vibration motor 14 is fixedly connected to the center of the front side of the top of the moving plate 9. The output end of the vibration motor 14 is in contact with the bottom of the placement seat 10.

[0023] As a technical optimization of this utility model, the combination of damping contraction rod 12 and stabilizing spring 13 at the bottom of the placement seat 10 provides good support for the placement seat 10. The setting of vibration motor 14 is also a major highlight. Its output end is in close contact with the bottom of the placement seat 10, and it can generate vibration during filling, which helps the molecular sieve to flow better in the material box 2, so that the molecular sieve can enter the discharge cylinder 4 more smoothly through the through hole, thereby improving the uniformity and speed of filling, ensuring that the molecular sieve can be tightly and evenly filled into the molecular sieve cylinder, and improving the filling quality.

[0024] refer to Figure 3 The surface of the compression spring 7 is covered with a retractable rubber sleeve 15. The top end of the rubber sleeve 15 is fixedly connected to the top of the inner wall of the material box 2, and the bottom end of the rubber sleeve 15 is fixedly connected to the top of the disc 5. The surface of the discharge cylinder 4 is covered with a retractable anti-splash sleeve 16. The top end of the anti-splash sleeve 16 is fixedly connected to the bottom of the material box 2, and the bottom end of the anti-splash sleeve 16 is fixedly connected to the top of the push ring 8.

[0025] As a technical optimization of this utility model, a rubber sleeve 15 is fitted onto the surface of the compression spring 7. Its expandable nature allows it to change with the expansion and contraction of the compression spring 7, thus protecting the compression spring 7 and preventing the molecular sieve from entering the compression spring 7 and affecting its normal use. A splash guard 16 is fitted onto the surface of the discharge cylinder 4. Its top is fixed to the bottom of the material box 2, and its bottom is fixed to the top of the push ring 8. This can effectively prevent the molecular sieve from splashing out during the filling process, keep the working environment clean, and also avoid the waste of molecular sieve, thereby improving resource utilization.

[0026] refer to Figure 3 The inner wall of the circular groove is fixedly connected to a first sealing sleeve 17, the surface of the discharge cylinder 4 is slidably connected to the inner wall of the first sealing sleeve 17, and the upper surface of the circular rod 6 is slidably connected to a second sealing sleeve 18, the surface of the second sealing sleeve 18 is fixedly connected to the inner wall of the material box 2.

[0027] As a technical optimization of this utility model, the sealing performance of the device is enhanced by setting a first sealing sleeve 17 and a second sealing sleeve 18. The first sealing sleeve 17 is fixed to the inner wall of the circular groove and slidably connected to the surface of the discharge cylinder 4, which can prevent the molecular sieve from leaking from the gap between the discharge cylinder 4 and the circular groove, ensuring the sealing and accuracy of the filling process. The second sealing sleeve 18 is slidably connected above the surface of the circular rod 6 and fixed to the inner wall of the material box 2, preventing external impurities from entering the interior of the material box 2, and also ensuring the smoothness of the circular rod 6 during the sliding process, further improving the stability and reliability of the device.

[0028] refer to Figure 3 T-shaped blocks 19 are fixedly connected to both the left and right sides of the movable plate 9. Slide grooves 20 that cooperate with the T-shaped blocks 19 are opened on both the left and right sides of the inner wall of the base 1. The surface of the T-shaped blocks 19 is slidably connected to the inner wall of the slide grooves 20.

[0029] As a technical optimization of this utility model, by setting the T-shaped block 19 and the slide groove 20 in cooperation, the T-shaped block 19 slides in the slide groove 20, providing a precise guiding effect for the up and down movement of the moving plate 9, ensuring that the moving plate 9 can move smoothly along the predetermined trajectory. This not only improves the stability of the movement of the moving plate 9, but also ensures the positional accuracy of the placement seat 10 and the molecular sieve cylinder during the movement process, so that the molecular sieve cylinder can be accurately aligned with the discharge cylinder 4, improving the filling accuracy and efficiency, and avoiding problems such as filling failure or unevenness caused by movement deviation.

[0030] refer to Figure 2 A magnetic sealing strip 21 is fixedly connected to the rear side of the top of the material box 2, and the top of the magnetic sealing strip 21 is magnetically connected to the bottom of the sealing cover 3.

[0031] As a technical optimization of this utility model, by setting a magnetic sealing strip 21 and magnetically connecting it to the bottom of the sealing cover 3, a tight fit between the sealing cover 3 and the material box 2 can be ensured. During the operation of the device, this effectively prevents external dust and impurities from entering the material box 2, thus ensuring the purity of the molecular sieve inside the material box 2. At the same time, the magnetic connection makes the opening and closing of the sealing cover 3 more convenient and quick. When adding molecular sieve, simply open the sealing cover 3 gently. After adding, the sealing cover 3 will automatically adhere to the magnetic sealing strip 21, improving the convenience of operation and the overall performance of the device.

[0032] The working principle and usage process of this utility model are as follows: In use, open the sealing cover 3 and add sufficient molecular sieve into the material box 2. Then close the sealing cover 3 and place the molecular sieve cylinder into the placement groove at the top of the placement seat 10, ensuring that its injection port is aligned with the discharge cylinder 4, preparing for subsequent filling operations. Next, activate the electric telescopic rod 11, causing it to retract and move the moving plate 9 at the bottom of the base 1 upwards. The placement seat 10 rises accordingly, and the molecular sieve cylinder also moves upwards until its top contacts the pushing ring 8 on the surface of the discharge cylinder 4. The electric telescopic rod 11 continues to retract, and the molecular sieve cylinder pushes the pushing ring 8 to continue moving upwards, thereby moving the discharge cylinder 4 upwards. At this time, the through hole on the surface of the discharge cylinder 4 enters the material box 2. Then, the electric telescopic rod 11 is closed. Since the diameter of the through hole is larger than the diameter of the molecular sieve, the molecular sieve in the material box 2 will enter the discharge cylinder 4 through the through hole, and then enter the molecular sieve cylinder through the bottom of the discharge cylinder 4, completing the filling process of the molecular sieve. After filling is completed, the electric telescopic rod 11 is activated to extend it, driving the moving plate 9 and the placement seat 10 to move downwards, taking out the filled molecular sieve cylinder. At the same time, the discharge cylinder 4 is reset by the rebound pressure of the compression spring 7, and the through hole moves to the outside of the material box 2, sealing the material box 2 for the next filling, effectively improving the filling efficiency and accuracy of the molecular sieve.
