Description

Technical Field

[0001] The utility model relates to the technical field of boiler container detection, and particularly relates to a leakage detection device for a boiler pressure vessel. Background Technique

[0002] Boiler pressure vessels are the full names of boilers and pressure vessels. Because they belong to special equipment, they play an important role in production and life and are also used in a small amount in industrial production. Pressure vessels will age after long-term use. Aging pressure vessels are prone to leakage accidents during use, affecting the safe production of enterprises.

[0003] Among them, a leakage detection device for a boiler pressure vessel disclosed in the patent application No. CN202022194216.X is also an increasingly mature technology. Start the second water pump, and the second water pump introduces the water in the water storage tank into the detection tank through the fourth water pipe and the first water pipe. Start the air inflation pump to inflate the inside of the boiler pressure vessel body. If bubbles are found around the boiler pressure vessel body, it means that the boiler pressure vessel body leaks and cannot be used. Otherwise, the boiler pressure vessel body is okay. When the detection of the boiler pressure vessel body is completed, through the first water pump, the water in the detection tank can be introduced into the water storage tank through the second water pipe and the third water pipe. Then control the hydraulic press to drive the connecting hard pipe to move upward through the fixing ring, so that the connecting hard pipe is separated from the boiler pressure vessel body. Subsequently, open the sealing door to replace another boiler pressure vessel body. On the one hand, it effectively detects whether the boiler pressure vessel body leaks. On the other hand, the water in the water storage tank can be recycled, and through the hydraulic press, the installation and disassembly of the connecting hard pipe and the boiler pressure vessel body can be effectively completed.

[0004] Based on this, while agreeing with the advantages of the above products, there are still the following defects:

[0005] For this kind of detection device, since it requires the human eye to find bubbles, if the gap on the boiler pressure vessel is very small, the generated bubbles will be very small. Since the human eye cannot see them outside the detection tank, it may increase the risk of safety accidents. Content of the Utility Model

[0006] The purpose of the utility model is to provide a leakage detection device for a boiler pressure vessel to solve the problem that the human eye cannot see very small gaps outside the detection tank proposed in the above background technique.

[0007] The embodiment of the utility model provides a leakage detection device for a boiler pressure vessel, which includes a detection tank and a water storage tank. A boiler body is arranged inside the detection tank. A detection component is arranged at the top of the boiler body. A matching component vertically penetrates through the top of the detection tank. A clamping component is arranged in the middle of the inner walls on both sides of the detection tank;

[0008] Among them, the detection component includes a connecting pipe of a flange plate connected to an exhaust pipe at the top end of the boiler body through bolts. The connecting pipe of the flange plate penetrates through the middle of the top end of the detection box and extends out of the top end. A foam collar is arranged at the top end of the connecting pipe of the flange plate. An air outlet pipe of an air inflation pump is movably arranged at the top end of the connecting pipe of the flange plate. The air inflation pump is located at the top end of the detection box;

[0009] The matching component includes a sleeve. A sliding cavity is formed inside the sleeve. A top plate is arranged inside the sliding cavity and extends out of one side surface of the sleeve. A connecting rod is vertically arranged at the bottom end of the top plate and is connected to a floating plate at the bottom end. The connecting rod penetrates through the top end of the detection box. A scale line is arranged on one side surface of the outside of the sleeve. The sleeve is located on the symmetry plane of the air inflation pump.

[0010] In this embodiment, the foam collar enables the air outlet pipe of the air inflation pump to be closely attached to the foam collar, avoiding gas leakage. The air inflation pump inflates the inside of the boiler body. Water is loaded inside the detection box. If there is a leak inside the boiler body, due to the action of gas pressure, it will push the floating plate, the connecting rod and the top plate to move upward along the sleeve. The top plate cooperates with the scale line of the sleeve, so that it can easily judge whether the boiler body leaks.

[0011] In an implementation scheme of the present utility model, clamping components include fixed blocks horizontally arranged on both inner walls of the detection box. A return spring is arranged inside the fixed block. One end of the return spring is provided with a convex block and extends out of the fixed block to be connected to a clamping block. Rubber pads are arranged at the opposite ends of the clamping blocks.

[0012] In this scheme, by squeezing the clamping blocks and the convex blocks, the return spring is compressed to move the clamping blocks and the convex blocks backward, which is convenient for replacing the boiler body. After replacement, the convex blocks are released, and through the elastic action of the return spring, the clamping blocks limit and clamp both sides of the boiler body.

[0013] In an implementation scheme of the present utility model, a first water pump and a second water pump are respectively arranged between the detection box and the water storage tank. The bottom end of the water inlet pipe of the first water pump is connected to a branch pipe. The branch pipe penetrates through one side surface of the water storage tank. The drain pipe of the first water pump penetrates through one side surface of the detection box. The water inlet pipe of the second water pump penetrates through one side surface of the detection box. The drain pipe of the second water pump penetrates through one side surface of the water storage tank.

[0014] In this scheme, the first water pump conveniently transports the water inside the water storage tank to the inside of the detection box, and the second water pump pumps the water inside the detection box back to the inside of the water storage tank again.

[0015] In an embodiment of the present utility model, a placement rack is provided in the middle of the inner bottom end of the detection box.

A handle is provided in the middle of one side of the outer wall of the box door. A transparent observation window is provided on one side of the detection box away from the water storage tank.

[0016] In this solution, the boiler body can be stably placed inside the detection box through the placement rack. Pulling the handle facilitates opening the box door, which is convenient for replacing other boiler bodies for detection. The sealing layer prevents gas and water from leaking through the gaps of the box door when it is closed. The observation window facilitates checking whether the water level inside the detection box reaches the bottom end of the floating plate.

[0017] In an embodiment of the present utility model, legs are provided around the bottom ends of the detection box and the water storage tank. An installation frame is provided on one side of the first water pump and is fixed to one side of the water storage tank by screws.
