Description

Technical Field

[0001] This utility model relates to the field of cold slag machine technology, and in particular to a water-cooled wall tube assembly for a cold slag machine with a leakage detection function. Background Technology

[0002] The slag cooler is a key hub connecting the boiler furnace and the subsequent slag conveying system. Its core function is to rapidly cool the high-temperature slag discharged from the furnace to a safe temperature. Among them, the water-cooled wall tube assembly is the key heat exchange component of the slag cooler. It is usually composed of multiple parallel seamless steel tubes, with cooling water flowing inside the tubes, and heat exchange is achieved through the tube walls to achieve cooling.

[0003] In actual operation, water-cooled pipes may experience leaks due to long-term exposure to high temperature, high pressure, and slag abrasion. These leaks may be difficult to detect in time, potentially leading to equipment failure or even safety accidents. Utility Model Content

[0004] The purpose of this utility model is to provide a water-cooled wall tube assembly for a slag cooler with a leakage detection function. This can solve the problem that in actual operation, water-cooled tubes may experience leakage problems such as weld cracking and tube wall corrosion perforation due to long-term exposure to high temperature, high pressure and slag abrasion. It is difficult to detect leakage in time, which may lead to equipment failure or even safety accidents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water-cooled wall tube assembly for a slag cooler with leakage detection function, comprising an annular water tank, a main detection mechanism, and a backup detection mechanism. The annular water tank comprises two sets, with protective shells fixedly installed on adjacent sides of the two sets of annular water tanks. The main detection mechanism is located outside the annular water tank and includes an internally threaded tube. The outer walls of the two sets of annular water tanks are respectively fixedly connected to one end of one set of internally threaded tubes, and the internally threaded tubes are connected to the interior of the annular water tanks. The backup detection mechanism is located outside the protective shell and includes a water collection tank, a thin water pipe, and a strip-shaped capacity window. The bottom of the water collection tank is fixedly connected to one end of the thin water pipe, and the thin water pipe is connected to the interior of the water collection tank. A strip-shaped opening is provided on the outer wall of the thin water pipe, and a strip-shaped capacity window is embedded inside the strip-shaped opening.

[0006] Preferably, the main detection mechanism also includes pressure sensors. A pressure sensor is threadedly installed on the inner wall of each of the two sets of internally threaded pipes to detect the water pressure of the circulating cooling water in the pipe group in real time, promptly detect water leakage and carry out repairs, prevent serious water leakage from causing equipment failure, and minimize the occurrence of safety accidents.

[0007] Preferably, the backup detection mechanism further includes a sealing cover and an auxiliary plate. The bottom of the protective shell is fixedly connected to the top of the water collection tank, and the water collection tank is connected to the inside of the protective shell. The other end of the thin water pipe is threaded with a sealing cover, and the bottom of the sealing cover is fixedly installed with an auxiliary plate. When the pressure sensor fails, the leaked cooling water can be collected in the thin water pipe, ensuring that the staff can detect the leak in time. By using dual methods to detect the leak, the availability and practicality of the device are improved.

[0008] Preferably, the bottom of the water collection tank is provided with two sets of symmetrically arranged inclined surfaces.

[0009] Preferably, multiple sets of annularly distributed water-cooling pipes are fixedly installed on the adjacent sides of the two sets of annular water tanks. The water-cooling pipes are connected to the interior of both sets of annular water tanks and are located inside the protective shell.

[0010] Preferably, a set of connecting pipes is fixedly installed on the outer wall of each of the two sets of annular water tanks, and a flange ring is fixedly installed at one end of the connecting pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This water-cooled wall tube assembly for a slag cooler, equipped with a leak detection function, uses a combination of internally threaded pipes and pressure sensors to monitor the water pressure of the circulating cooling water within the assembly in real time. This allows for timely detection and repair of leaks, preventing serious equipment failures and minimizing the risk of accidents. Furthermore, the combined use of a water collection tank, a thin water pipe, a strip-shaped capacity window, a sealing cap, and auxiliary plates ensures that leaked cooling water is collected in the thin water pipe when the pressure sensor malfunctions, allowing for prompt detection of leaks. This dual-method approach to leak detection enhances the device's usability and practicality. Attached Figure Description

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a water-cooled wall tube assembly for a slag cooler with leakage detection function, comprising an annular water tank 1, a main detection mechanism 3, and a backup detection mechanism 4. The annular water tank 1 comprises two sets, with protective shells 2 fixedly installed on adjacent sides of the two sets of annular water tanks 1. The main detection mechanism 3 is located outside the annular water tank 1 and includes an internally threaded pipe 301. The outer walls of the two sets of annular water tanks 1 are respectively fixedly connected to one end of one set of internally threaded pipes 301, and the internally threaded pipes 301 communicate with the interior of the annular water tank 1. The backup detection mechanism 4 is located outside the protective shell 2 and includes a water collection tank 401 and a thin water pipe 402. The bottom of the water collection tank 401 is fixedly connected to one end of the thin water pipe 402, and the thin water pipe 402 is connected to the interior of the water collection tank 401. The outer wall of the thin water pipe 402 has a strip-shaped opening, and the strip-shaped capacity window 403 is installed inside the strip-shaped opening. The bottom of the water collection tank 401 is provided with two sets of symmetrically arranged inclined surfaces. Multiple sets of annularly distributed water-cooling pipes 8 are fixedly installed on the adjacent sides of the two sets of annular water tanks 1. The water-cooling pipes 8 are connected to the interior of the two sets of annular water tanks 1 and are located inside the protective shell 2. A set of connecting pipes 6 are fixedly installed on the outer wall of the two sets of annular water tanks 1 respectively, and a flange ring 7 is fixedly installed at one end of the connecting pipe 6.

[0016] Secondly, the main detection mechanism 3 also includes a pressure sensor 302. A pressure sensor 302 is threadedly installed on the inner wall of each of the two sets of internally threaded pipes 301 to detect the water pressure of the circulating cooling water in the pipe group in real time, promptly detect water leakage and carry out repairs, prevent serious water leakage from causing equipment failure, and minimize the occurrence of safety accidents.

[0017] Furthermore, the backup detection mechanism 4 also includes a sealing cover 404 and an auxiliary piece 405. The bottom of the protective shell 2 is fixedly connected to the top of the water collection tank 401. The water collection tank 401 is connected to the inside of the protective shell 2. The other end of the thin water pipe 402 is threaded with a sealing cover 404. The bottom of the sealing cover 404 is fixedly installed with an auxiliary piece 405. When the pressure sensor 302 fails, the leaked cooling water can be collected in the thin water pipe 402, ensuring that the staff can detect the leak in time. By using dual means to detect the leak, the availability and practicality of the device are improved.

[0018] Working principle: When using this device, the pressure sensor 302 is rotated and screwed into the internally threaded pipe 301 for installation. Two sets of connecting pipes 6 are connected to the inlet and outlet pipes of the cooling water circulation equipment via the flange ring 7. Cooling water is injected into the annular water tank 1 through one set of connecting pipes 6, then dispersed into each water-cooling pipe 8 for cooling, and finally discharged through the other set of connecting pipes 6. During cooling water circulation, the pressure sensor 302 detects the water pressure. When the water pressure is lower than the set value, it indicates a leak, and an alarm is triggered. When the pressure sensor 302 fails to detect a leak, the coolant will leak into the protective housing 2 and flow along the inner wall of the protective housing 2 into the water collection tank 401. After passing through the inclined surface at the bottom of the water collection tank 401, the coolant will enter the thin water pipe 402. The staff can observe whether there is liquid in the thin water pipe 402 through the strip capacity window 403. If there is liquid, it indicates a leak, and repairs can be carried out in time. By rotating the sealing cover 404 through the auxiliary plate 405, it can be removed from the thin water pipe 402 to drain the leaked coolant.

[0019] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
