Description

Technical Field

[0001] This utility model relates to the field of nitrogen sealing technology, and in particular to a fully automatic intelligent nitrogen sealing filling equipment for oxalyl chloride and phosphorus oxychloride. Background Technology

[0002] When storing oxalyl chloride and phosphorus oxychloride, nitrogen is introduced to prevent oxygen from damaging them. Nitrogen's inertness provides protection. However, existing intelligent nitrogen-sealing filling equipment uses intelligent filling and releasing of nitrogen based on the pressure inside the tank. This results in the equipment being fixedly installed on the tank, and the tank and equipment are used together. If the tank is damaged or not in use, the equipment cannot be disassembled to nitrogen-seale other tanks, affecting the equipment's adaptability. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where tanks and equipment are used in conjunction, and when a tank is damaged or not in use, the equipment cannot be disassembled to nitrogen-seale other tanks, thus affecting the adaptability of the equipment. Therefore, this invention proposes a fully automatic intelligent nitrogen-sealing filling equipment for oxalyl chloride and phosphorus oxychloride.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a fully automatic intelligent nitrogen sealing filling device for oxalyl chloride and phosphorus oxychloride, including a storage tank. Conical hoods are fitted onto both the nitrogen inlet and outlet pipes of the storage tank. Both conical hoods are fixed by a fixing mechanism. Connecting pipes are connected to both conical hoods, and solenoid valves are installed on both connecting pipes. A nitrogen collection tank is connected to one connecting pipe, and a nitrogen storage tank is connected to the other connecting pipe. Sealing gaskets are installed on the inner walls of both conical hoods. The two conical hoods are fixed by the fixing mechanism. A controller is installed on the nitrogen storage tank, and the controller is signal-connected to the solenoid valves.

[0006] Preferably, the fixing mechanism includes two connecting ears, and a bidirectional telescopic rod is fixedly connected to the two connecting ears. A fixing block is fixedly connected to both ends of the bidirectional telescopic rod, and a fixing rod is fixedly connected to each of the two fixing blocks. The two fixing rods pass through the connecting ears, and the two connecting ears are connected to the conical cover through an adjustment mechanism.

[0007] Preferably, the adjusting mechanism includes two threaded rods, both of which are rotatably connected to the connecting lugs via bearings, and both threaded rods are threaded through and connected to a fixing lug, which is fixedly connected to the conical cover.

[0008] Preferably, each of the two threaded rods is fixedly connected to a pulley, and a belt is fitted onto the two pulleys.

[0009] Preferably, the two fixing rods are provided with anti-slip textures on their opposite inner sides.

[0010] Preferably, the storage tank is equipped with a feed valve and a discharge valve.

[0011] Preferably, the sealing gasket is made of polyurethane rubber material.

[0012] The present invention proposes a fully automatic intelligent nitrogen sealing filling equipment for oxalyl chloride and phosphorus oxychloride. The advantages are as follows: by using a fixing mechanism to fix the conical hood, the sealing gasket and the nitrogen inlet and outlet pipes are brought into contact and sealed, which makes it easy to disassemble the equipment and use it for nitrogen sealing with storage tanks of different specifications, thus improving the adaptability of the equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-3An automated intelligent nitrogen sealing filling device for oxalyl chloride and phosphorus oxychloride includes a storage tank 14, which is equipped with a feed valve and a discharge valve. Conical shrouds 7 are fitted onto both the nitrogen inlet and outlet pipes of the storage tank 14. Because the inner wall of the conical shroud 7 is conical, it can be connected to two nitrogen inlet and outlet pipes of different diameters. The conical shrouds 7 are fixed by a fixing mechanism. Connecting pipes 2 are connected to both conical shrouds 7, and solenoid valves 4 are installed on both connecting pipes 2. Pressure gauges 3 are installed on the connecting pipes 2 and are connected to a controller 5. A nitrogen collection tank 15 is connected to one of the connecting pipes 2, and a nitrogen collection tank 15 is connected to the other connecting pipe 2. The device includes a nitrogen storage tank 1, with sealing gaskets installed on the inner walls of two conical shrouds 7. The two conical shrouds 7 are fixed by a fixing mechanism. A controller 5 is installed on the nitrogen storage tank 1, and the controller 5 is connected to a solenoid valve 4. By controlling the pressure gauge 3 of the solenoid valve 4 through the controller 5, nitrogen is filled into the storage tank 14 or released, ensuring pressure stability and playing a role in intelligent nitrogen sealing. The fixing mechanism also fixes the conical shrouds 7 to ensure that the sealing gaskets and nitrogen inlet and outlet pipes abut against each other to create a tight seal. This facilitates the disassembly of the device and allows it to be connected to storage tanks of different specifications for nitrogen sealing, improving the adaptability of the device.

[0019] The fixing mechanism includes two connecting ears 11, with a bidirectional telescopic rod 16 fixedly connected to each connecting ear 11. A fixing block 12 is fixedly connected to both ends of the bidirectional telescopic rod 16, and a fixing rod 13 is fixedly connected to each fixing block 12. The two fixing rods 13 pass through the connecting ears 11. The two connecting ears 11 are connected to the conical cover 7 via an adjusting mechanism. The adjusting mechanism includes two threaded rods 10, both of which are rotatably connected to the connecting ears 11 via bearings. A fixing ear 9 is threaded through each of the threaded rods 10 and fixedly connected to the conical cover 7. When the bidirectional telescopic rod 16 is retracted, the fixing rod 13 abuts against the nitrogen inlet / outlet pipe. By rotating the threaded rod 10, the position of the fixing ear 9 on the threaded rod 10 is adjusted, causing the conical cover 7 to descend and press the sealing gasket against the nitrogen inlet / outlet pipe to achieve a seal.

[0020] During connection, the conical cover 7 is fitted onto the nitrogen inlet or outlet pipe. Then, the bidirectional telescopic rod 16 retracts, and the fixing rod 13 abuts against the nitrogen inlet or outlet pipe. Then, the threaded rod 10 is rotated to adjust the position of the fixing ear 9 on the threaded rod 10, so that the conical cover 7 descends and the sealing gasket abuts against the nitrogen inlet and outlet pipes to achieve a sealing effect. The controller 5 controls the solenoid valve 4 and the pressure gauge 3 to fill nitrogen into the storage tank 14 or release nitrogen. When materials are discharged or added, the pressure inside the storage tank 14 is kept stable.

[0021] Example 2: In Example 1, when using an adjustment mechanism for adjustment, it is necessary to rotate both threaded rods 10 simultaneously, which increases the inconvenience of operation. (Refer to...) Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 1, pulleys 6 are fixedly connected to both threaded rods 10, and belts 8 are sleeved on the two pulleys 6. The belts 8 and pulleys 6 are used to transmit power, so that rotating one threaded rod 10 can drive the other threaded rod 10 to rotate, which is beneficial to the convenience of operation.

[0022] The inner sides of the two fixing rods 13 are provided with anti-slip texture, which helps to increase the fixing effect.

[0023] The gasket is made of polyurethane rubber, which prevents it from tearing and helps extend its service life.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
