Description

Technical Field

[0001] This utility model relates to the field of deoxygenation equipment technology, specifically a carbon-adding purification and deoxygenation device. Background Technology

[0002] The carbon-added deoxygenation purification nitrogen generator refers to a nitrogen generator based on the PSA pressure swing adsorption nitrogen generator with the addition of a carbon-supported purification device. It improves the purity of the original nitrogen to ≥99.999% high-purity nitrogen. It uses a high-efficiency catalyst for deoxygenation without activation and has a wide deoxygenation range. It is suitable for processes with high oxygen content and no excessive requirements for excess hydrogen.

[0003] The carbon molecular sieve in the nitrogen generator is a crucial component, directly affecting the equipment's performance. Therefore, it is essential to regularly check the adsorption efficiency of the carbon molecular sieve and replace it promptly if necessary. When replacing the carbon molecular sieve, first stop the compressed air supply, unload the internal pressure of the nitrogen generator system until all pressure gauges return to zero, disconnect the system power, then remove the top cover of the packed tower one by one, clean the carbon molecular sieve from the packed tower, check for any structural damage, and ensure there are no residues in the packing before filling. Next, place a layer of palm fiber pad at the bottom, then lay some activated alumina, and finally begin filling the packed tower with carbon molecular sieve, ensuring the tower is fully filled and compacted.

[0004] In existing equipment, when replacing the carbon molecular sieve in the packed tower, workers need to remove the original carbon molecular sieve from the tower. The bottom of the packed tower is usually equipped with a discharge port. Workers knock on the outer wall of the packed tower to make the carbon molecular sieve flow out of the discharge port quickly. However, repeatedly knocking on the packed tower not only reduces work efficiency, but may also cause the connection between the packed tower and other equipment to become loose. Summary of the Invention

[0005] Based on this, the purpose of this utility model is to provide a carbon addition purification and deoxygenation device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon-added purification and deoxygenation device, comprising a packed tower, wherein a discharge port is installed at the lower end of the packed tower, and a connecting rod is movably installed on the inner wall of the discharge port, a limiting block is installed at one end of the connecting rod, and a sliding groove is provided at the other end of the limiting block, and the sliding groove and the limiting block are engaged with each other, and a through hole is provided at one end of the connecting rod, and the through hole is located on the outer wall of the packed tower.

[0007] By adopting the above technical solution, the connecting rod is moved within the packed tower by pulling and shifting it left and right, allowing the material inside the tower to gradually flow out from the outlet. This reduces the need for workers to repeatedly tap the outer wall of the packed tower, greatly improving work efficiency and effectively extending the service life of the packed tower. Furthermore, the positioning rod and through-hole design allow the connecting rod to be positioned on the outer wall of the positioning rod when there is no need to remove material from the tower, facilitating the removal of one end of the connecting rod during secondary operations.

[0008] The present invention is further configured such that the outer wall of the discharge port is provided with external threads, and a plug is fitted on the outer wall of the discharge port, and the inner wall of the plug is provided with internal threads.

[0009] By adopting the above technical solution, the discharge port is threadedly connected to the plug to seal the discharge port, which also makes it easier for staff to replace the carbon molecular sieve.

[0010] The present invention is further configured such that the chute is arc-shaped and is arranged opposite to the discharge port.

[0011] By adopting the above technical solution, the carbon molecular sieve can be effectively relaxed in the packed tower, thereby improving working efficiency.

[0012] The present invention is further configured such that the slide groove and the limiting block are T-shaped, and the limiting block is movably installed in the slide groove.

[0013] By adopting the above technical solution, the chute limits the limiting block, making it difficult for the limiting block to detach from the chute, and facilitating the shaking of the carbon molecular sieve by the connecting rod.

[0014] The present invention is further configured such that the connecting rod is in the form of a mesh, the diameter of the mesh holes is larger than the diameter of the carbon molecular sieve, and the connecting rod is made of silicone rubber.

[0015] By adopting the above technical solution, silicone rubber is composed of elements such as silicon, carbon, oxygen, and hydrogen. However, silicone rubber does not react with carbon because the molecular structure of silicone rubber contains a large number of Si-O bonds and Si-C bonds, which makes silicone rubber have high chemical stability.

[0016] The present invention is further configured such that the through hole is a wavy circular hole, and the diameter of the through hole is larger than the width of a finger.

[0017] By adopting the above technical solution, it is convenient for workers to place their fingers inside the through hole to move and pull the connecting rod.

[0018] The present invention is further configured such that a positioning rod is installed on the inner wall of the packed tower, and the positioning rod is located at the top of the outlet.

[0019] By adopting the above technical solution, the positioning rod is cylindrical and fixedly connected to the inner wall of the packed tower.

[0020] The present invention is further configured such that the through hole is sleeved on the outer wall of the positioning rod, and the through hole and the positioning rod are engaged.

[0021] By adopting the above technical solution, the positioning rod engages with the through hole, thereby limiting the position of the connecting rod.

[0022] In summary, the present invention has the following main advantages: 1. This utility model, through the setting of the connecting rod, allows the connecting rod to move inside the packed tower by pulling and moving it left and right, so that the material inside the packed tower gradually flows out from the discharge port, reducing the need for workers to repeatedly knock on the outer wall of the packed tower, greatly improving work efficiency and effectively extending the service life of the packed tower. 2. By setting up a positioning rod and a through hole, this utility model limits the position of the connecting rod by fitting the through hole onto the outer wall of the positioning rod when there is no need to remove the material inside the packed tower, making it convenient to remove one end of the connecting rod during secondary operations.

[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. Example 1:

[0027] A carbon-added purification and deoxygenation device, such as Figure 1 - Figure 4As shown, the system includes a packed tower 1, with a discharge port 2 installed at the lower end of the packed tower 1. A connecting rod 12 is movably installed on the inner wall of the discharge port 2. A limiting block 11 is installed at one end of the connecting rod 12, and a sliding groove 10 is provided at the other end of the limiting block 11. The sliding groove 10 and the limiting block 11 are engaged with each other. A through hole 13 is provided at one end of the connecting rod 12, and the through hole 13 is located on the outer wall of the packed tower 1. By setting the connecting rod 12, pulling the connecting rod 12 and moving the connecting rod 12 left and right can make the connecting rod 12 move inside the packed tower 1, so that the material inside the packed tower 1 gradually flows out from the discharge port 2. This reduces the need for workers to repeatedly knock on the outer wall of the packed tower 1, greatly improves work efficiency, and effectively improves the service life of the packed tower 1. By setting the positioning rod 3 and the through hole 13, when it is not necessary to remove the material inside the packed tower 1, the through hole 13 is fitted onto the outer wall of the positioning rod 3 to limit the position of the connecting rod 12, making it easy to remove one end of the connecting rod 12 during secondary operations.

[0028] Please see Figure 1 , Figure 2 The outer wall of the discharge port 2 is provided with external threads, and a plug is fitted on the outer wall of the discharge port 2. The inner wall of the plug is provided with internal threads. The discharge port 2 is threadedly connected to the plug to seal the discharge port 2 and facilitate the replacement of the carbon molecular sieve by the staff.

[0029] Please see Figure 1 , Figure 2 The chute 10 is arc-shaped and is positioned opposite to the discharge port 2. The opposite positioning of the chute 10 and the discharge port 2 effectively relaxes the carbon molecular sieve in the packed tower 1, thereby improving working efficiency.

[0030] Please see Figure 4 The chute 10 and the limiting block 11 are T-shaped, and the limiting block 11 is movably installed in the chute 10. The chute 10 limits the limiting block 11, making it difficult for the limiting block 11 to detach from the chute 10, so that the connecting rod 12 can shake the carbon molecular sieve.

[0031] Please see Figure 1 - Figure 3 The connecting rod 12 is mesh-like, and the diameter of the mesh holes is larger than that of the carbon molecular sieve. The connecting rod 12 is made of silicone rubber, which is composed of elements such as silicon, carbon, oxygen, and hydrogen. However, silicone rubber does not react with carbon because the molecular structure of silicone rubber contains a large number of Si-O bonds and Si-C bonds, which makes silicone rubber have high chemical stability.

[0032] Please see Figure 1 , Figure 3 The through hole 13 is a wavy circular hole, and the diameter of the through hole 13 is larger than the width of a finger, so that the operator can put his / her finger in the through hole 13 to move and pull the connecting rod 12. Example 2:

[0033] Please see Figure 3 The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, a positioning rod 3 is added to one end of the discharge port 2, so that the positioning rod 3 engages with the through hole 13 to limit the connection rod 12. A positioning rod 3 is provided at the top of the discharge port 2, and the positioning rod 3 is located on the inner wall of the packed tower 1. The through hole 13 is sleeved on the outer wall of the positioning rod 3. The positioning rod 3 limits the position of the connecting rod 12, making it convenient for the staff to pick up and place the connecting rod 12.

[0034] The working principle of this utility model is as follows: When it is necessary to replace the carbon molecular sieve in the nitrogen generator, the original carbon molecular sieve must first be removed. With the equipment stopped, the operator opens the block on the outer wall of the discharge port 2, then removes the connecting rod 12 from the packed tower 1. The operator manually pulls the connecting rod 12 to accelerate the falling of the carbon molecular sieve at the upper end of the packed tower 1, and swings the connecting rod 12 left and right, so that the connecting rod 12 drives the limiting block 11 to move in the slide 10, which loosens the compacted carbon molecular sieve in the packed tower 1, making it easier for the carbon molecular sieve to fall and improving work efficiency. Furthermore, a positioning rod 3 is installed on the inner wall of the packed tower 1, and the positioning rod 3 is located at the top of the outlet 2. The positioning rod 3 engages with the through hole 13, and the positioning rod 3 limits the position of the through hole 13, thereby allowing one end of the connecting rod 12 to hang on the inner wall of the packed tower 1, which facilitates secondary operations by the staff and also improves the sealing performance of the packed tower 1.
