Description

Technical Field

[0001] This application relates to the field of slag cooler technology, and more particularly to a water-cooled drum slag cooler. Background Technology

[0002] In industries such as thermal power generation and metallurgy, the cooling and treatment of high-temperature solid waste is a key link in the production process. Traditional methods such as natural cooling and air cooling can reduce the temperature of waste to a certain extent, but they have obvious shortcomings. Natural cooling is time-consuming and inefficient, and cannot meet the strict time efficiency requirements of industrial production. While air cooling can improve the cooling speed to a certain extent, its cooling effect is easily affected by environmental factors and its stability is insufficient.

[0003] In recent years, with the advancement of technology, water-cooled slag coolers have gradually become the mainstream choice. They bring hot slag into contact with cooling water inside the cylinder to reduce its temperature, thereby making the slag material more stable. However, traditional water-cooling equipment has problems such as low cooling efficiency, high energy consumption, and high maintenance costs.

[0004] Therefore, this application provides a water-cooled drum slag cooler. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a water-cooled drum slag cooler, which overcomes the deficiencies of existing technologies. It aims to solve the problems that, in recent years, with the advancement of technology, water-cooled slag coolers have gradually become the mainstream choice. They bring hot slag into contact with cooling water inside the drum to reduce its temperature, thereby making the slag material more stable. However, traditional water-cooling equipment suffers from problems such as low cooling efficiency, high energy consumption, and high maintenance costs.

[0006] To achieve the above objectives, this application provides the following technical solution: a water-cooled drum slag cooler, comprising a support frame, a cross brace fixedly installed on the top of the support frame, a limiting bracket fixedly installed at the top of the support frame, a drum mechanism rotatably connected inside the limiting bracket, the drum mechanism comprising an outer shell, an inner shell fixedly connected inside the outer shell, a cavity provided between the outer shell and the inner shell, a water-cooling mechanism provided in the cavity, a protruding ring fixedly installed at the open end of the outer shell, a feeding mechanism provided on one side of the drum mechanism at the top of the support frame, and a driving mechanism provided on the other side of the drum mechanism at the top of the support frame. The drive mechanism includes a coupling shaft, which is fixedly installed on one side of the housing. A first roller shaft is fixedly installed at one end of the coupling shaft, and a limit plate is fixedly installed at one end of the first roller shaft. A first pulley is fixedly installed on the outer surface of the first roller shaft. A reciprocating motor is fixedly installed at the top of the bracket directly below the coupling shaft. A second roller shaft is fixedly installed at the output end of the reciprocating motor. A fixed seat is rotatably connected to one end of the second roller shaft. The bottom end of the fixed seat is fixedly installed at the top of the bracket. A second pulley is fixedly installed on the outer surface of the second roller shaft. A belt is drivingly connected between the second pulley and the first pulley.

[0007] By adopting the above technical solution, high-temperature solid waste is fed into the inner shell through a feeding mechanism. The heat released by the high-temperature waste inside the inner shell is absorbed by a water-cooling mechanism. At the same time, a reciprocating motor drives the second roller shaft to rotate, which in turn drives the second pulley to rotate. The belt drives the first pulley to rotate, and the first pulley drives the roller mechanism to rotate through a connecting shaft. This allows the high-temperature solid waste inside the inner shell to have more full contact with the water-cooling mechanism, resulting in more uniform cooling, improving heat exchange efficiency, and saving energy consumption. The reciprocating motor drives the roller mechanism to rotate through the second pulley, the first pulley, and the belt, ensuring stable rotation speed of the roller mechanism. At the same time, the drive mechanism has a simple structure and is easy to maintain.

[0008] As a preferred technical solution of this application, the top of the bracket is provided with auxiliary mechanisms on both sides of the limiting bracket. The auxiliary mechanism includes two sets of rotating seats, and the top of the two sets of rotating seats is rotatably connected to a rotating shaft. The outer surface of the rotating shaft is fixedly installed with a drive wheel, and the outer surface of the roller mechanism is fixedly installed with two sets of rotating rings, and the outer surface of the rotating rings is in rolling contact with the two sets of drive wheels below them.

[0009] By adopting the above technical solution, when the roller mechanism is driven to rotate by the drive mechanism, the outer shell is linked to the rotation of four sets of drive wheels. Under the auxiliary rotation of the outer shell by the four sets of drive wheels, the roller mechanism is more stable during rotation. At the same time, the two sets of auxiliary mechanisms also provide support for the roller mechanism, further improving the stability of the roller mechanism during rotation.

[0010] As a preferred technical solution of this application, the water cooling mechanism includes a cooling pipe, which is fixedly installed between the outer shell and the inner shell. A water inlet pipe is fixedly installed on one side of the cooling pipe, and a drain pipe is fixedly installed on the side of the cooling pipe away from the water inlet pipe. Valves are fixedly installed inside both the water inlet pipe and the drain pipe.

[0011] By adopting the above technical solution, the flow rate of water entering and exiting the water supply pipe and the drainage pipe is controlled by valves, which helps to control the flow rate of water in the cooling pipe to meet the cooling effect requirements of different waste materials.

[0012] As a preferred technical solution of this application, the feeding mechanism includes a vertical frame, which is fixedly installed on the top of the support. Two sets of annular frames are fixedly installed on the top of the vertical frame. A slag hopper is fixedly installed on the inner ring of the two sets of annular frames. A slag pipe is fixedly installed at the bottom of the slag hopper. The end of the slag pipe away from the slag hopper extends into the interior of the inner shell.

[0013] By adopting the above technical solution, the slag hopper is fixed by the upright frame and the ring frame, which improves the stability of the slag hopper. The high-temperature waste slag in the slag hopper enters the inner shell through the slag discharge pipe, which improves the practicality during use.

[0014] As a preferred technical solution of this application, a heat conduction plate is fixedly installed inside the inner shell.

[0015] By adopting the above technical solution, the heat transfer plate enables the temperature inside the inner shell to be transferred to the cooling pipe more quickly, further improving the cooling efficiency.

[0016] As a preferred technical solution of this application, flow sensors are fixedly installed on the inner walls of both the water inlet pipe and the drain pipe, and a controller is fixedly installed on the side wall of the bracket. Both sets of flow sensors are signal connected to the controller.

[0017] By adopting the above technical solution, flow sensors are fixedly installed on the inner walls of both the water inlet pipe and the drain pipe, which facilitates the recording of water flow in the cooling pipe. The controller monitors the cooling water flow in the cooling pipe in real time, which helps to keep the cooling effect at its best.

[0018] As a preferred technical solution of this application, a temperature sensor is fixedly installed on the inner wall of the inner shell, and the temperature sensor is signal-connected to the controller, and the controller is electrically connected to the control terminal of the reciprocating motor.

[0019] By adopting the above technical solution, the temperature of the waste material inside the inner shell is monitored in real time by a temperature sensor, and the signal is transmitted to the reciprocating motor. The reciprocating motor adjusts its speed according to the temperature signal, which is beneficial for precise control of the cooling effect.

[0020] As a preferred technical solution of this application, the slag discharge pipe is inclined, and the bottom end of the slag discharge pipe is located inside the inner shell.

[0021] By adopting the above technical solution and setting the slag discharge pipe at an angle, the waste can smoothly enter the inner shell, further improving the waste processing efficiency.

[0022] The beneficial effects of this application are:

[0023] 1. High-temperature solid waste is fed into the inner shell via a feeding mechanism. The heat released by the high-temperature waste inside the inner shell is absorbed by a water-cooling mechanism. Simultaneously, a reciprocating motor drives the second roller shaft to rotate, which in turn drives the second pulley to rotate. The belt drives the first pulley to rotate, and the first pulley drives the roller mechanism to rotate via a connecting shaft. This allows the high-temperature solid waste inside the inner shell to have more thorough contact with the water-cooling mechanism, resulting in more uniform cooling, improved heat exchange efficiency, and energy savings. The reciprocating motor drives the roller mechanism to rotate via the second pulley, the first pulley, and the belt, ensuring stable rotation speed. The drive mechanism has a simple structure and is easy to maintain.

[0024] 2. When the roller mechanism is driven to rotate by the drive mechanism, the outer shell is linked to the rotation of four sets of drive wheels. With the auxiliary rotation of the outer shell by the four sets of drive wheels, the roller mechanism is more stable during rotation. At the same time, the two sets of auxiliary mechanisms also provide support for the roller mechanism, further improving the stability of the roller mechanism during rotation.

A first pulley 604 is fixedly installed on the outer surface of shaft 602. A reciprocating motor 605 is fixedly installed at the top of bracket 1 directly below the connecting shaft 601. A second roller 606 is fixedly installed at the output end of the reciprocating motor 605. A fixed seat 607 is rotatably connected to one end of the second roller 606. The bottom end of the fixed seat 607 is fixedly installed at the top of bracket 1. A second pulley 609 is fixedly installed on the outer surface of the second roller 606.

The water cooling mechanism 7 includes a cooling pipe 701, which is fixedly installed between the outer shell 401 and the inner shell 402. A water inlet pipe 702 is fixedly installed on one side of the cooling pipe 701. A drain pipe 703 is fixedly installed on the side of the cooling pipe 701 away from the water inlet pipe 702. Valves are fixedly installed inside both the water inlet pipe 702 and the drain pipe 703.

[0032] High-temperature solid waste is fed into the inner shell 402 by the feeding mechanism 5. The water cooling mechanism 7 absorbs the heat released by the high-temperature waste in the inner shell 402. At the same time, the reciprocating motor 605 drives the second roller shaft 606 to rotate, which in turn drives the second pulley 609 to rotate. The belt 608 drives the first pulley 604 to rotate. The first pulley 604 drives the roller mechanism 4 to rotate through the connecting shaft 601. This allows the high-temperature solid waste in the inner shell 402 to have more complete contact with the water cooling mechanism 7, and to be cooled more evenly, thereby improving heat exchange efficiency and saving energy consumption. The reciprocating motor 605 drives the roller mechanism 4 to rotate through the second pulley 609, the first pulley 604, and the belt 608, ensuring that the rotation speed of the roller mechanism 4 is stable. The drive mechanism 6 has a simple structure and is easy to maintain. The flow rate of water entering and leaving the water supply pipe 702 and the drain pipe 703 is controlled by the valve, which helps to control the flow rate of water in the cooling pipe 701 to meet the cooling requirements of different waste materials.

[0033] Reference Figure 2-4The top of the support 1 is provided with auxiliary mechanisms 8 on both sides of the limiting support 3. The auxiliary mechanism 8 includes two sets of rotating seats 801. The top of the two sets of rotating seats 801 is rotatably connected to the rotating shaft 802. The outer surface of the rotating shaft 802 is fixedly installed with a drive wheel 803. The outer surface of the roller mechanism 4 is fixedly installed with two sets of rotating rings 804, and the outer surface of the rotating rings 804 is in rolling contact with the two sets of drive wheels 803 below them. The feeding mechanism 5 includes a vertical frame 501. The vertical frame 501 is fixedly installed at the top of the support 1. The top of the vertical frame 501 is fixedly installed with two sets of ring frames 502. The inner ring of the two sets of ring frames 502 is fixedly installed with a slag hopper 503. The bottom end of the slag hopper 503 is fixedly installed with a slag pipe 504. The end of the slag pipe 504 away from the slag hopper 503 extends into the interior of the inner shell 402.

[0034] When the drum mechanism 4 is driven to rotate by the drive mechanism 6, the outer shell 401 is linked to the four sets of drive wheels 803 to rotate. Under the auxiliary rotation of the outer shell 401 by the four sets of drive wheels 803, the drum mechanism 4 is more stable during rotation. At the same time, the two sets of auxiliary mechanisms 8 also provide support for the drum mechanism 4, further improving the stability of the drum mechanism 4 during rotation. The slag hopper 503 is fixed by the upright frame 501 and the ring frame 502, which improves the stability of the slag hopper 503. The high-temperature waste slag in the slag hopper 503 enters the inner shell 402 through the slag discharge pipe 504, which improves the practicality during use.

[0035] Reference Figure 1-3 A heat conduction plate 10 is fixedly installed inside the inner shell 402; a temperature sensor 12 is fixedly installed on the inner wall of the inner shell 402, and the temperature sensor 12 is connected to the controller 13 by signal, and the controller 13 is electrically connected to the control terminal of the reciprocating motor 605; the heat conduction plate 10 enables the temperature inside the inner shell 402 to be transferred to the cooling pipe 701 more quickly, further improving the cooling efficiency; the temperature sensor 12 monitors the temperature of the waste material inside the inner shell 402 in real time and transmits the signal to the reciprocating motor 605, and the reciprocating motor 605 adjusts its speed according to the temperature signal, which is conducive to precise control of the cooling effect.

[0036] Reference Figure 1-3 Flow sensors are fixedly installed on the inner walls of both the water inlet pipe 702 and the drain pipe 703, and a controller 13 is fixedly installed on the side wall of the bracket 1. Both sets of flow sensors are connected to the controller 13. The slag discharge pipe 504 is inclined, and the bottom end of the slag discharge pipe 504 is located inside the inner shell 402. The heat conduction plate 10 enables the temperature inside the inner shell 402 to be transferred to the cooling pipe 701 more quickly, further improving the cooling efficiency. The inclined design of the slag discharge pipe 504 allows waste to enter the inner shell 402 smoothly, further improving the waste processing efficiency.

[0037] Working principle: High-temperature solid waste is fed into the inner shell 402 by the feeding mechanism 5. The water cooling mechanism 7 absorbs the heat released by the high-temperature waste in the inner shell 402. Simultaneously, the reciprocating motor 605 drives the second roller shaft 606 to rotate, which in turn drives the second pulley 609 to rotate. The belt 608 drives the first pulley 604 to rotate, and the first pulley 604 drives the roller mechanism 4 to rotate through the connecting shaft 601. This allows the high-temperature solid waste in the inner shell 402 to have more thorough contact with the water cooling mechanism 7, resulting in more uniform cooling, improved heat exchange efficiency, and reduced energy consumption. The reciprocating motor 605 drives the roller mechanism 4 to rotate via the second pulley 609, the first pulley 604, and the belt 608, ensuring the stable rotation speed of the roller mechanism 4. At the same time, the drive mechanism 6 has a simple structure and is easy to maintain. When the roller mechanism 4 is driven to rotate by the drive mechanism 6, the outer shell 401 is linked to the four sets of drive wheels 803 to rotate. Under the auxiliary rotation of the outer shell 401 by the four sets of drive wheels 803, the rotation of the roller mechanism 4 is more stable. At the same time, the two sets of auxiliary mechanisms 8 also provide support for the roller mechanism 4, further improving the stability of the roller mechanism 4 during rotation.

[0038] Among them, the flow rate of water entering and exiting the water supply pipe 702 and the drain pipe 703 is controlled by valves, which helps to control the flow rate of water in the cooling pipe 701 to meet the cooling effect requirements of different waste materials. The slag hopper 503 is fixed by the upright frame 501 and the ring frame 502, which improves the stability of the slag hopper 503. The high-temperature waste slag in the slag hopper 503 enters the inner shell 402 through the slag discharge pipe 504, which improves the practicality during use.

[0039] Meanwhile, the heat conduction plate 10 enables the temperature inside the inner shell 402 to be transferred to the cooling pipe 701 more quickly, further improving the cooling efficiency.

[0040] In addition, the temperature of the waste inside the inner shell 402 is monitored in real time by the temperature sensor 12 and the signal is transmitted to the reciprocating motor 605. The reciprocating motor 605 adjusts its speed according to the temperature signal, which is conducive to precise control of the cooling effect. The slag discharge pipe 504 is inclined, which allows the waste to enter the inner shell 402 smoothly, further improving the waste processing efficiency.
