Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a low-point drain cleaner with high safety. Background Technology

[0002] During the operation of chemical plants, solids settle at the lowest points of pipelines, frequently causing blockages in valves located at these points. When draining oil from pipelines or equipment, a common practice for clearing these blockages is to use a wire or iron rod to pry them open. However, this method carries significant risks when dealing with acidic or toxic materials. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses a highly safe low-point drain cleaner, comprising a pipe fitting with a drain rod inserted upwards at the lower end. The pipe fitting includes a pipe body with a second plug inside. The drain rod includes a member that interference-fits through the second plug. A branch port is fixedly connected to the upper side wall of the pipe body, located above the second plug. The drain cleaner is fixedly connected to a low-level pipe opening in a chemical pipeline. The branch port is used to discharge residual material from the pipeline. However, because the opening is low, solid matter can accumulate and cause blockages. Therefore, the member is provided to push away the blockage, allowing the material to drain smoothly from the branch port.

[0004] Preferably, a valve is fixedly connected to the branch pipe opening. During the unblocking process, the valve is in a closed state.

[0005] Preferably, the upper end of the pipe body is an upper connection port, and a movable joint is provided at the upper connection port. The pipe fitting is fixedly connected to the chemical pipeline through the movable structure.

[0006] Preferably, the upper end of the rod is provided with a ball, and the lower end of the rod is fixedly connected to a grip section. The grip section facilitates pushing and pulling the rod up and down.

[0007] Preferably, a first plug is provided at the lower end of the pipe body, and the cavity between the first and second plugs is filled with fluid. Both the first and second plugs are used to improve sealing. Simultaneously, the fluid pressure is greater than the pressure of the chemical pipeline, greatly preventing material leakage below the second plug.

[0008] Preferably, the tube body has an inner limiting member inside, which abuts against the second seal. The outer wall of the inner limiting member is threaded, and a regular hexagonal through hole is provided in the middle. The inner limiting member is rotated and fixed inside the tube body using a tool.

[0009] Preferably, a first plug is fixedly connected to the lower end of the tube, and the first plug abuts upward against the first seal, with the middle of the first plug penetrating through it. The first plug serves to limit and fix the first seal.

[0010] Preferably, an oil injection pipe is fixedly connected to the side wall of the pipe body. A second plug is threaded onto the oil injection pipe, and the second plug is hollow. A valve core is installed inside the oil injection pipe, and the conical surface of the valve core fits against the inner wall of the second plug. A spring is installed on one side of the valve core, and the other end of the spring abuts against the inner wall of the oil injection pipe. The valve core, spring, and other components constitute the structure of a one-way valve, which facilitates fluid injection into the chamber between the first and second plugs and prevents overflow.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. When using this drain cleaner, install and fix it to the lowest point of the chemical pipeline. The drain rod can push the solid matter deposited there upwards, so that the material can be sent out from the valve.

[0013] 2. It is equipped with a first seal and a second seal, and fluid is injected into the first seal and the second seal to prevent the material in the chemical pipeline from leaking downward, thereby improving the sealing and safety. Attached Figure Description

[0020] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0021] like Figures 1 to 3 As shown, a high-safety low-point drain cleaner includes a pipe fitting 2, and a drain rod 1 is provided at the lower end of the pipe fitting 2. The drain rod 1 pushes the blockage upward to ensure that the material in the chemical loop is smoothly delivered. The pipe fitting 2 includes a pipe body 23, and a second plug 25 is provided inside the pipe body 23. The drain rod 1 includes a rod 12, and the rod 12 is interference-fitted through the second plug 25. The interference fit improves the sealing between the two. A branch pipe port 26 is fixedly connected to the upper side wall of the pipe body 23, and the branch pipe port 26 is located above the second plug 25. That is, after the blockage is cleared, the material in the chemical pipeline can be discharged from the branch pipe port 26.

[0022] A valve 3 is fixedly connected to the branch pipe 26. During cleaning, the valve 3 is in a closed state.

[0023] The upper end of the pipe body 23 is the upper connection port 27, and a movable connector 4 is provided at the upper connection port 27.

[0024] A ball 13 is provided at the upper end of the rod 12. The ball 13 is designed to prevent the unblocking rod 1 from falling off the second plug 25 due to factors such as gravity. Note that the second plug 25 has a certain degree of elasticity. During assembly, the ball 13 can be directly inserted into the second plug 25. A grip section 11 is fixedly connected to the lower end of the rod 12 for easy gripping of the unblocking rod 1. Furthermore, after the unblocking rod 1 is assembled, a cleaning brush can be installed and fixed on the ball 13 from the upper end of the pipe body 23.

[0025] The lower end of the pipe body 23 is provided with a first plug 22, which further improves the sealing effect. The cavity between the first plug 22 and the second plug 25 is filled with fluid. Note that the fluid here is set to high pressure, at least greater than the pressure in the chemical pipeline, to prevent material from leaking downwards to the second plug 25.

[0026] The inner limiter 24 is provided inside the tube body 23, and the inner limiter 24 abuts against the second seal 25. The outer wall of the inner limiter 24 is provided with threads, that is, it is fixedly connected to the inner wall of the tube body 23 by means of threaded connection. A regular hexagonal through hole is provided in the middle. By using a regular hexagonal wrench in the regular hexagonal through hole, the inner limiter 24 can be rotated to fix the second seal 25.

[0027] The lower end of the tube body 23 is fixedly connected to a first plug 21, and the first plug 21 abuts against the first seal 22. The upper side wall of the first plug 21 is threaded and threadedly connected to the tube body 23. At the same time, the lower end of the first plug 21 has a regular hexagonal structure, which can be locked and rotated with a wrench. The middle part of the first plug 21 is through, that is, the part 12 passes through the first plug 21 and the first seal 22.

[0028] An oil injection pipe 210 is fixedly connected to the side wall of the pipe body 23. The oil injection pipe 210 injects fluid into the chamber between the first plug 22 and the second plug 25. A second plug 28 is threaded onto the oil injection pipe 210 and is hollow. A valve core 29 is installed inside the oil injection pipe 210, and the conical surface of the valve core 29 fits against the inner wall of the second plug 28. A spring 211 is installed on one side of the valve core 29, and the other end of the spring 211 abuts against the inner wall of the oil injection pipe 210. Under the action of the spring 211, the inner walls of the valve core 29 and the second plug 28 are in close contact, so that the chamber between the first plug 22 and the second plug 25 is in a closed state. The structure of the valve core 29, the spring 211, and the second plug 28 constitutes the function of a one-way valve.
