Description

Technical Field

[0001] This utility model belongs to the technical field of fixed connection structure for chlorine cylinders, and in particular relates to a fixed connection structure for chlorine cylinders. Background Technology

[0002] In modern industrial production systems, chlorine, with its strong oxidizing properties and active chemical properties, has become an indispensable key chemical raw material in many fields such as papermaking, textiles, water treatment, and chemical synthesis. Taking the papermaking industry as an example, chlorine is used in the pulp bleaching process to effectively remove lignin and improve the whiteness and quality of paper. In the field of chemical synthesis, chlorine participates in the synthesis reactions of various organic compounds and is an important raw material for the production of products such as plastics, pesticides, and pharmaceutical intermediates. In actual production processes, the large number of one-ton chlorine cylinders used are the main carriers for storing and transporting chlorine. However, the traditional method of connecting chlorine cylinders to pipelines is extremely cumbersome, so a fixed connection structure for chlorine cylinders is needed to solve this problem.

[0003] However, the existing fixed connection structure of chlorine cylinders often requires the delivery pipeline to be fixed to the chlorine cylinder through the connection structure before the valve can be opened to deliver chlorine. After the connection is completed, the staff needs to approach the cylinder again to open the valve. This not only wastes time but also increases the time that personnel are exposed to potentially hazardous environments, significantly reducing overall production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed connection structure for chlorine cylinders. By setting a valve mechanism, it solves the problem that in the use of existing fixed connection structures for chlorine cylinders, it is often necessary to fix the delivery pipe to the chlorine cylinder through the connection structure before opening the valve to deliver chlorine. After the connection is completed, the operator needs to approach the cylinder again to open the valve, which is not only time-consuming, but also increases the time that personnel are exposed to potentially hazardous environments, significantly reducing the overall production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a fixed connection structure for chlorine gas cylinders, including a chlorine gas cylinder, on which a valve mechanism and a quick disassembly mechanism are provided;

[0007] The top of the chlorine cylinder is connected to an outlet pipe, and a delivery pipe is sleeved on the outer wall of the outlet pipe. The outlet pipe is connected to the delivery pipe. The valve mechanism includes a positioning ring fixedly connected to the outer wall of the outlet pipe. The left side of the delivery pipe is in contact with the positioning ring. A cross support frame is fixedly connected to the inner wall of the outlet pipe. The quick disassembly mechanism includes an L-shaped support plate fixedly connected to the outer wall of the delivery pipe. A limit plate is fixedly connected to the left side of the positioning ring.

[0008] Furthermore, a matching ring is fixedly connected to the inner wall of the air outlet pipe, a piston is installed inside the air outlet pipe, the piston is matched with the matching ring, a telescopic rod is fixedly connected to the right side of the cross support frame, the right side of the telescopic rod is fixedly connected to the piston, a spring is sleeved on the outer wall of the telescopic rod, the left side of the spring is fixedly connected to the cross support frame, and the right side of the spring is fixedly connected to the piston.

[0009] Furthermore, a Y-shaped support frame is fixedly connected to the inner wall of the conveying pipe, and a push rod is fixedly connected to the left side of the Y-shaped support frame, the left side of the push rod being adapted to the piston.

[0010] Furthermore, a cylinder is fixedly connected to the top of the L-shaped support plate, a limiting rod passes through the cylinder, the limiting rod is slidably connected to the cylinder, and the bottom of the limiting rod passes through the L-shaped support plate.

[0011] Furthermore, a circular slider is fixedly connected to the outer wall of the limiting rod, the outer wall of the circular slider is slidably connected to the cylinder, and a second spring is sleeved on the outer wall of the limiting rod. The top of the second spring is fixedly connected to the cylinder, and the bottom of the second spring is fixedly connected to the circular slider.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting a valve mechanism, during the installation of the delivery pipe, the push rod on the Y-shaped support frame will also move to the left along with the movement of the delivery pipe. During this process, the push rod will press against the piston and drive the piston to move to the left until the connection between the outlet pipe and the delivery pipe is completed. At this time, the piston will also disengage from the adapter ring, and a gap will be created between the piston and the adapter ring. Chlorine gas will flow into the delivery pipe through this gap and be guided to the required delivery position. During this process, the telescopic rod and spring 1 will be compressed. When spring 1 is compressed, it will also undergo elastic deformation and generate elastic force. When the delivery ends, the limit rod is pulled again to remove the delivery pipe. At this time, the push rod will also disengage from the piston, and the piston will be reset under the action of the elastic force of spring 1 and restore the sealing state with the adapter ring. This allows the chlorine delivery channel to be opened automatically without the need for manual operation of the valve to control the gas flow. This achieves automated gas delivery control, improves the convenience and efficiency of operation, and effectively prevents chlorine gas leakage after delivery, ensuring the safety of the entire delivery process and reducing harm to the environment and personnel.

[0014] 2. By setting up a quick-release mechanism, when it is necessary to install the conveying pipe on the air outlet pipe, the limiting rod can be pulled to move it upward. At this time, the circular slider will also move accordingly and compress the second spring. During the compression process, the second spring will undergo elastic deformation and generate elastic force. Then, the conveying pipe is inserted into the air outlet pipe until the left side of the conveying pipe hits the positioning ring. Then, the limiting rod is released. At this time, the limiting rod will move downward under the action of the elastic force of the second spring and cooperate with the L-shaped support plate and the limiting plate to complete the connection between the air outlet pipe and the conveying pipe. This ensures that the insertion depth of the conveying pipe is accurate and achieves precise positioning. After releasing the limiting rod, the limiting rod, under the action of the elastic force of the second spring, cooperates with the L-shaped support plate and the limiting plate to firmly fix the conveying pipe on the air outlet pipe, ensuring the stability of the connection. No complicated installation steps and tools are required, which improves the connection efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A push rod 217 is fixedly connected to the left side of the Y-shaped support frame 216. The left side of the push rod 217 is adapted to piston 213. By setting valve mechanism 2, the chlorine conveying channel can be automatically opened without manual operation of the valve to control the gas flow.

[0027] The quick assembly / disassembly mechanism 3 includes an L-shaped support plate 311 fixedly connected to the outer wall of the conveying pipe 102; a limit plate 312 fixedly connected to the left side of the positioning ring 210; a cylinder 313 fixedly connected to the top of the L-shaped support plate 311; a limit rod 314 passing through the cylinder 313 and slidably connected to the cylinder 313; the bottom of the limit rod 314 passing through the L-shaped support plate 311 and the limit plate 312; a circular slider 315 fixedly connected to the outer wall of the limit rod 314 and slidably connected to the cylinder 313; and the limit rod 315 extending through the cylinder 313. A second spring 316 is fitted on the outer wall of the rod 314. The top of the second spring 316 is fixedly connected to the cylinder 313, and the bottom of the second spring 316 is fixedly connected to the circular slider 315. By setting a quick disassembly and assembly mechanism 3, the insertion depth of the conveying pipe 102 can be accurately ensured and precise positioning can be achieved. After the limiting rod 314 is released, the limiting rod 314 cooperates with the L-shaped support plate 311 and the limiting plate 312 under the elastic force of the second spring 316 to firmly fix the conveying pipe 102 on the air outlet pipe 101, ensuring the stability of the connection. No complicated installation steps and tools are required, which improves the connection efficiency.

[0028] A specific application of this embodiment is as follows: In use, first connect the right side of the conveying pipe 102 to the desired conveying position, then pull the limiting rod 314 to move it upwards. At this time, the circular slider 315 will also move accordingly, compressing the second spring 316. During compression, the second spring 316 will undergo elastic deformation and generate elastic force. Then, insert the conveying pipe 102 onto the air outlet pipe 101 until the left side of the conveying pipe 102 reaches the positioning ring 210. Then release the limiting rod 314. At this time, the limiting rod 314 will move downwards under the elastic force of the second spring 316, cooperating with the L-shaped support plate 311 and the limiting plate 312 to complete the connection between the air outlet pipe 101 and the conveying pipe 102. During the installation of the conveying pipe 102, the top rod 217 on the Y-shaped support frame 216 will also move along with the conveying pipe 102. The piston moves to the left as the piston moves. During this process, the push rod 217 will press against the piston 213 and drive the piston 213 to move to the left until the connection between the outlet pipe 101 and the delivery pipe 102 is completed. At this time, the piston 213 also disengages from the adapter ring 212 and a gap is formed between the piston and the adapter ring 212. Chlorine gas flows into the delivery pipe 102 through this gap and is guided to the required delivery position. During this process, the telescopic rod 214 and the spring 215 will be compressed. When the spring 215 is compressed, it will also undergo elastic deformation and generate elastic force. When the delivery ends, the limit rod 314 is pulled again to remove the delivery pipe 102. At this time, the push rod 217 will also disengage from the piston 213, and the piston 213 will be reset under the action of the elastic force of the spring 215 and restore the sealing state with the adapter ring 212.
