Description

Technical Field

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

[0002] Molecular sieves are loosely structured solid materials, typically processed into small spheres. They have strong absorption and filtration capabilities and are commonly used in waste gas and wastewater treatment, chemical processing, and other fields. Molecular sieves need to be filled into a sieve cylinder, which is then placed in the filtration environment to perform its filtration function. Therefore, a molecular sieve filling device is required to facilitate accurate and rapid filling of molecular sieves.

[0003] A prior patent (publication number: CN221772290U) discloses a molecular sieve filling device for an oxygen generator, including a base frame with an adsorption cylinder placed on top of the base frame, and a filling mechanism located above the adsorption cylinder. The filling mechanism includes a clamping component and a filling component. The filling component pours the material into the adsorption cylinder. A lifting structure drives a rotating rod in a leveling structure to extend into the adsorption cylinder, driving an electric push rod to move a leveling brush downwards, inserting the leveling brush into the molecular sieve. A rotating motor drives the rotating rod to rotate, causing the two leveling brushes to rotate, thereby stirring the molecular sieve in all directions and leveling its surface. At the same time, a vibration structure vibrates the adsorption cylinder up and down, making the upper surface of the molecular sieve even flatter and the molecular sieve more evenly distributed, thus improving the adsorption effect of the molecular sieve.

[0004] However, the above technical solution still has certain defects. In the process of feeding, the feed pipe is located on one side of the adsorption cylinder, which makes the material on the side closer to the feed pipe more during the feeding process. During the rotation of the flat brush, the material is blocked by the feed pipe, so there is more material on the side of the feed pipe, resulting in uneven material distribution inside the adsorption cylinder. Therefore, a molecular sieve filling device for oxygen generator is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a molecular sieve filling device for an oxygen generator to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a molecular sieve filling device for an oxygen generator, comprising a frame, a four-jaw chuck fixedly connected to the bottom end of the frame, an adsorption tower fixedly connected to the top end of the four-jaw chuck, and a feeding mechanism fixedly connected to the top end of the frame.

[0007] The feeding mechanism includes a feeding hopper, which is fixedly connected to the top of the frame. A discharge pipe is rotatably connected to the bottom of the feeding hopper. A connecting rod extending into the adsorption tower is slidably sleeved on the bottom of the inner wall of the discharge pipe. Multiple sets of stirring rods are hinged to the side wall of the connecting rod. A torsion spring is provided at the connection point between the stirring rod and the connecting rod.

[0008] As a preferred technical solution of the molecular sieve filling device for an oxygen generator according to this utility model, a motor located next to the feed pipe is fixedly connected to the top of the frame, and a gear set located between the feed pipe and the motor is provided at the top of the frame. One end of the gear set is connected to the output end of the motor, and the other end of the gear set is fixedly sleeved on the outer wall of the feed pipe.

[0009] As a preferred technical solution of the molecular sieve filling device for an oxygen generator according to this utility model, the top end of the connecting rod is fixedly connected to a pull rod extending into the inside of the feeding hopper, and the top end of the pull rod is fixedly connected to a pull ring.

[0010] As a preferred technical solution of the molecular sieve filling device for an oxygen generator according to this utility model, two sets of inclined rods are fixedly connected to the outer wall of the pull rod, and the ends of the inclined rods are cut obliquely downward.

[0011] As a preferred technical solution of the molecular sieve filling device for an oxygen generator according to the present invention, a rotating arm is fixedly sleeved on the outer wall of the feeding pipe, and a set of pushing blocks are fixedly connected to both ends of the rotating arm.

[0012] As a preferred technical solution of the molecular sieve filling device for an oxygen generator according to this utility model, two sets of striking rods are rotatably connected to the side wall of the frame. A torsion spring is provided at the connection between the striking rod and the frame. Two sets of protrusions are fixedly connected to the top of the two sets of striking rods respectively. The bottom end of the striking rod abuts against the side wall of the adsorption tower.

[0013] As a preferred technical solution of the molecular sieve filling device for an oxygen generator according to the present invention, the bottom end of the feeding pipe is provided with two sets of openings, and the two sets of openings are inclined to both sides respectively.

[0014] In summary, the present invention has the following main advantages:

[0015] 1. This utility model uses two sets of openings at the bottom of the feeding pipe to allow the material to fall into the adsorption tower. The feeding pipe rotates during the feeding process, which makes the material more evenly distributed inside the adsorption tower. The stirring rod stirs and mixes the material evenly, avoiding the problem of material accumulating on one side of the adsorption tower.

[0016] 2. This utility model prevents material from accumulating inside the feeding hopper by rotating the inclined rod inside the feeding hopper during the feeding process. In the above process, the pushing block rotates and contacts the protrusion, thereby pushing the striking rod to flip. Then, through the rebound force of the torsion spring, the bottom end of the striking rod strikes the side wall of the adsorption cylinder, so that the material inside the adsorption tower is vibrated and compacted evenly.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A molecular sieve filling device for an oxygen generator, such as Figures 1 to 4 As shown, it includes a frame 1, a four-jaw chuck 2 fixedly connected to the bottom end of the frame 1, an adsorption tower 3 fixedly connected to the top end of the four-jaw chuck 2, and a feeding mechanism 4 fixedly connected to the top end of the frame 1.

[0028] The feeding mechanism 4 includes a feeding hopper 401, which is fixedly connected to the top of the frame 1. A feeding pipe 402 is rotatably connected to the bottom of the feeding hopper 401. A connecting rod 403 extending into the adsorption tower 3 is slidably sleeved on the bottom of the inner wall of the feeding pipe 402. Multiple sets of stirring rods 404 are hinged to the side wall of the connecting rod 403. A torsion spring is provided at the connection point between the stirring rod 404 and the connecting rod 403. A motor 411 located next to the feeding pipe 402 is fixedly connected to the top of the frame 1. A gear set 412 is located between the feeding pipe 402 and the motor 411 at the top of the frame 1. One end of the gear set 412 is connected to the output end of the motor 411, and the other end of the gear set 412 is fixedly sleeved on the outer wall of the feeding pipe 402. The bottom end of the feed pipe 402 has two sets of openings, which are inclined to both sides. The top end of the connecting rod 403 is fixedly connected to a pull rod 405 extending into the feed hopper 401. The top end of the pull rod 405 is fixedly connected to a pull ring. The outer wall of the pull rod 405 is fixedly connected to two sets of inclined rods 406, the ends of which are cut downwards at an angle. The outer wall of the feed pipe 402 is fixedly fitted with a rotating arm 407. The two ends of the rotating arm 407 are fixedly connected to a set of pushing blocks 408. The side wall of the frame 1 is rotatably connected to two sets of striking rods 409. The striking rods 409 are provided with torsion springs at the connection with the frame 1. The top ends of the two sets of striking rods 409 are fixedly connected to two sets of protrusions 410. The bottom end of the striking rods 409 abuts against the side wall of the adsorption tower 3.

[0029] The material is poured into the feeding hopper 401, then falls into the discharge pipe 402. Through two openings at the bottom of the discharge pipe 402, it falls into the adsorption tower 3. During this process, the motor 411 drives the discharge pipe 402 to rotate via the gear set 412. This causes the discharge pipe 402 to rotate the connecting rod 403, which in turn rotates the stirring rod 404. As the stirring rod 404 rotates, the connecting rod 403 drives the pull rod 405, causing the two sets of inclined rods 406 to rotate, thus agitating the material inside the feeding hopper 401. After feeding is complete, pulling the pull rod 405 causes the connecting rod 403 to move upwards. During this process, the connecting rod 403 drives the stirring rod 404 upwards. As the stirring rod 404 moves upwards, it is blocked by the material, causing it to flip downwards. This makes the upward movement of the stirring rod 404 smoother. When the stirring rod 404 contacts the discharge pipe 402, it is again blocked and flipped. This causes the stirring rod 404 to adhere to the side wall of the connecting rod 403. Then, the connecting rod 403 drives the stirring rod 404 to slide out of the feed pipe 402 and the feeding hopper 401. When it is necessary to insert the connecting rod 403 into the feed pipe 402, the stirring rod 404 flips upwards and adheres to the side wall of the connecting rod 403, allowing the stirring rod 404 to pass through the feed pipe 402. After feeding is completed, when the stirring rod 404 is pulled out of the adsorption tower 3, the motor 411 drives the feed pipe 402 to continue... The continuous rotation causes the feed pipe 402 to drive the rotating arm 407 to rotate, and the rotating arm 407 to drive the push block 408 to rotate. When the push block 408 contacts the protrusion 410, it pushes the protrusion 410 to cause the striking rod 409 to flip, thereby torturing the torsion spring. After the push block 408 slides past the protrusion 410, the torsion spring rebounds and pushes the striking rod 409 to reset, so that the bottom end of the striking rod 409 strikes the side wall of the adsorption tower 3, thereby making the material inside the adsorption tower 3 vibrate evenly and make the material compacted.

[0030] In use, the material falls into the adsorption tower 3 through the two sets of openings at the bottom of the feeding pipe 402. The feeding pipe 402 rotates during the feeding process, making the material more evenly distributed inside the adsorption tower 3. The stirring rod 404 stirs and mixes the material evenly, avoiding the problem of material accumulating on one side of the adsorption tower 3. The parts not mentioned in this device are the same as or can be implemented using existing technology.
