Description

Technical Field

[0001] This utility model relates to the field of nitrogen replacement, and more specifically, to a nitrogen replacement device. Background Technology

[0002] In the pharmaceutical production process, it is necessary to quickly ventilate the sealed aluminum drums containing medicines by introducing nitrogen gas into them. This nitrogen sealing reduces the risk of oxidation of the medicines during storage. Currently, most aluminum drums requiring gas purging use specially designed caps, resulting in high production costs for each drum. This type of venting also poses certain safety hazards, including the risk of leakage. Operators need advanced professional skills to perform nitrogen purging by using a specially designed cap with an interface, replacing the cap with a standard one after purging.

[0003] Chinese utility model patent CN221724076U discloses a nitrogen purging device. This device includes a nitrogen inlet / outlet mechanism to address the issue of nitrogen directly contacting and mixing with the existing gas inside the purging chamber during nitrogen input. A baffle plate is also included to allow the nitrogen to push the existing gas out of the purging chamber. However, because the device's sealing door is hinged to the purging chamber, the hinge structure itself has some room for movement, as the door needs to rotate around the hinge point. Therefore, it is difficult to achieve a tight seal like a planar seal at this connection point, thus providing a possible channel for gas leakage.

[0004] Therefore, a nitrogen replacement device needs to be redesigned to address the aforementioned issues. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] The technical solution provided by this utility model:

[0027] Reference Figure 1-5 A nitrogen replacement device includes a replacement chamber 1. A fixing groove 6 is provided on one side of the replacement chamber 1. Two sliding grooves 7 are symmetrically provided on one side of the replacement chamber 1. Limiting grooves 8 are provided on the inner top and bottom walls of the two sliding grooves 7. Sliding blocks 11 are slidably connected in both sliding grooves 7. A sealing door 2 is fixedly connected to one side of the two sliding blocks 11. A connecting groove 15 is provided on one side of the sealing door 2. A fixing device is provided in the connecting groove 15, and the output end of the fixing device abuts against the inner bottom wall of the fixing groove 6. An installation groove 13 is provided on one side of the sealing door 2. A through groove 14 is provided on the inner top wall of the installation groove 13. A sealing device is provided in the installation groove 13, and the output end of the sealing device passes through the through groove 14 and is connected to the output end of the fixing device.

[0028] Furthermore, each slider 11 has a limit block 12 fixedly installed at its top and bottom, and the limit block 12 is slidably connected in the corresponding limit groove 8.

[0029] Furthermore, the fixing device includes a fixing rod 10, which is slidably connected in the connecting groove 15. One end of the fixing rod 10 abuts against the inner bottom wall of the fixing groove 6. A fixing block 5 is fixedly connected to the end of the fixing rod 10 away from the fixing groove 6. A connecting plate 4 is fixedly installed on the outer wall of the fixing rod 10, and one end of the connecting plate 4 is connected to the output end of the sealing device. By using the abutment between the fixing rod 10 and the fixing groove 6, the sealing door 2 can be limited to prevent the sealing door 2 from sliding easily.

[0030] Furthermore, the sealing device includes a spring 16, which is fixedly connected to the inner top wall of the mounting groove 13. One end of the spring 16 is fixedly connected to a sealing block 9, and a connecting rod 17 is fixedly installed on the upper end face of the sealing block 9. The spring 16 is sleeved on the outer wall of the connecting rod 17. One end of the connecting rod 17 passes through the through groove 14 and extends outward to install a lifting handle 3. The connecting plate 4 is fixedly connected to the outer wall of the connecting rod 17. The elastic properties of the spring 16 can keep the sealing block 9 in contact with the inner wall of the replacement box 1, thus effectively sealing the replacement box 1 and the sealing door 2.

[0031] Furthermore, the outer wall of the lifting handle 3 is provided with multiple anti-slip protrusions. It should be noted that the anti-slip protrusions can increase the friction between the operator's hand and the lifting handle 3.

[0032] Furthermore, two stops 18 are symmetrically fixedly installed on the upper end face of the sealing block 9. It should be noted that the stops 18 can prevent the sealing block 9 from directly contacting the inner top wall of the mounting groove 13, which would cause damage to the sealing block 9.

[0033] Furthermore, the center line of the connecting groove 15 and the center line of the fixing groove 6 are the same straight line.

[0034] In practical use, the working principle of this utility model is as follows:

[0035] First, pull the lifting handle 3. The lifting handle 3 can drive the connecting rod 17 to move. The connecting rod 17 will drive the sealing block 9 to move synchronously, so that the sealing block 9 slides into the mounting groove 13 until the two stops 18 abut against the inner top wall of the mounting groove 13. During this process, the spring 16 will be compressed by the sealing block 9. While the connecting rod 17 moves with the lifting handle 3, the connecting rod 17 can drive the fixing rod 10 to move synchronously through the connecting plate 4. Then the fixing rod 10 will be pushed away from the fixing groove 6. At this time, the sealing door 2 can be slid. The sealing door 2 will drive the slider 11 to move in the sliding groove 7 until the slider 11 drives the limiting block 12 to abut against the inner side wall of the limiting groove 8. At this time, the sealing door 2 can be opened, and the interior of the replacement box 1 will be completely exposed.

[0036] When the sealing door 2 is closed, the elastic properties of the spring 16 allow the sealing block 9 to remain in contact with the inner wall of the replaced box 1, thus effectively sealing the replaced box 1.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
