Description

Technical Field

[0001] This utility model relates to the field of slag cooler technology, specifically a slag cooler with anti-slag-spraying function. Background Technology

[0002] The slag cooler, also known as a slag inlet box, slag outlet box, power transmission device, base frame, and electrical control system, mainly consists of a cylinder, slag inlet box, slag outlet box, power transmission device, base frame, and electrical control system. Both the cylinder and the partition frame adopt a water-cooled wall structure, and slag guide plates are welded on the inner wall of the cylinder and the partition frame. The main function of the slag cooler is to cool the ash and slag in the furnace through the water-cooled wall structure, ensuring the normal operation and safety of the boiler. The slag cooler plays a vital role in the boiler system. It can effectively control the temperature inside the furnace and prevent the temperature inside the furnace from becoming too high, thereby protecting the boiler equipment from damage.

[0003] However, existing methods for processing slag in slag coolers present the following problems: if the slag contains excessive moisture or has high humidity, it may generate steam or bubbles during processing, increasing the likelihood of slag ejection and posing safety hazards. Furthermore, there is a lack of methods for pre-treating the slag before it is introduced into the cooler. Therefore, it is necessary to design corresponding technical solutions to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a slag cooler with anti-slag-spraying function, which solves the technical problem that if the slag being processed contains too much moisture or has high humidity, it may cause the slag to generate steam or bubbles during processing, thereby increasing the possibility of slag spraying and posing a safety hazard. There is a lack of means to pre-treat the slag before it is introduced.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slag cooler with anti-slag-spraying function, comprising a slag cooler body and a slag pretreatment component installed at the slag inlet box at the end of the slag cooler body. The slag pretreatment component includes a slag guide pipe, a heated feed cylinder, a drive motor, a rotating rod, spiral blades, a draining mechanism, and a steam guiding mechanism. The end of the slag guide pipe is connected to the heated feed cylinder. The drive motor is installed at the outer end of the heated feed cylinder, and its power output end is connected to the rotating rod. The spiral blades are arranged in several groups and evenly installed on the rotating rod. A drain port is provided at the bottom of the heated feed cylinder. A filter screen is installed at the drain outlet. The draining mechanism is installed directly below the drain outlet and fixed to the heated feed cylinder. The draining mechanism includes an arc-shaped liquid collection hood and a drainage pipe connected to the bottom of the arc-shaped liquid collection hood. The lower end of the drainage pipe is connected to a liquid storage container. The steam guiding mechanism is installed at the upper left corner of the heated feed cylinder and includes a suction pipe, a blower, an air intake pipe, and a water-cooling pipe. The suction pipe is connected to the heated feed cylinder. The blower is installed above the suction pipe and its bottom is connected to the air intake pipe. The water-cooling pipe is fitted onto the air intake pipe. The end of the water-cooling pipe is connected to a connecting pipe. The lower end of the connecting pipe is connected to the liquid storage container.

[0006] As a preferred embodiment of this utility model, the heated feed cylinder includes a cylinder body and several sets of electric heating plates installed inside the cylinder body. The several sets of electric heating plates have an arc-shaped structure and are embedded in the inner wall of the cylinder body.

[0007] In a preferred embodiment of this utility model, the arc-shaped liquid collection hood has an overall arc-shaped structure and closed structures at both ends, and the bottom of the arc-shaped liquid collection hood is connected to the drainage pipe.

[0008] In a preferred embodiment of this utility model, the water-cooled pipe includes an outer pipe, a water inlet pipe, a water outlet pipe, and a drain pipe. The outer pipe is fitted onto the air inlet pipe, and the water inlet pipe is disposed inside the outer pipe with its two ends connected to the water outlet pipe and the drain pipe, respectively.

[0009] In a preferred embodiment of this utility model, the drainage tube has a spiral structure and is laid on the surface of the air drainage tube.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model improves upon existing slag coolers by incorporating a slag pretreatment component into the slag inlet box. Before the slag is introduced, the slag is guided and treated by the slag pretreatment component. During the guiding process, any water that may be present in the slag is drained outwards. Simultaneously, any moisture that may be present in the slag is heated and evaporated. The evaporated moisture is then diverted, cooled, and drained outwards, thereby achieving the purpose of slag pretreatment and reducing the occurrence of slag spray due to excessive moisture or high humidity in the slag.

[0012] 2. The slag pretreatment component designed in this utility model can pre-treat and dry the slag before it is introduced, thereby reducing the problem of slag spraying during subsequent cold slag machining. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: a slag cooler with anti-slag-spraying function, including a slag cooler body 1 and a slag pretreatment component installed at the slag inlet box at the end of the slag cooler body 1. The slag pretreatment component includes a slag guide pipe 2, a heated feed cylinder 3, a drive motor 4, a rotating rod 5, spiral blades 6, a liquid discharge mechanism 7, and a steam guiding mechanism 8. The end of the slag guide pipe 2 is connected to the heated feed cylinder 3. The drive motor 4 is installed at the outer end of the heated feed cylinder 3 and its power output end is connected to the rotating rod 5. The spiral blades 6 are arranged in several groups and evenly installed on the rotating rod 5. A liquid discharge port 9 is opened at the bottom of the heated feed cylinder 3, and a filter screen 10 is installed at the liquid discharge port 9 for liquid discharge. Mechanism 7 is installed directly below the drain port 9 and fixed on the heated feed cylinder 3. The drain mechanism 7 includes an arc-shaped liquid collection hood 11 and a drainage pipe 12 connected to the bottom of the arc-shaped liquid collection hood 11. The lower end of the drainage pipe 12 is connected to a liquid storage container 13. The steam guiding mechanism 8 is installed at the upper left corner of the heated feed cylinder 3 and includes a suction pipe 14, a blower 15, an air duct 16, and a water cooling pipe 17. The suction pipe 14 is connected to the heated feed cylinder 3. The blower 15 is installed above the suction pipe 14 and its bottom is connected to the air duct 16. The water cooling pipe 17 is fitted onto the air duct 16. The end of the water cooling pipe 17 is connected to a connecting pipe 18. The lower end of the connecting pipe 18 is connected to the liquid storage container 13.

[0019] Further improvements, such as Figure 2 As shown, the heated feed cylinder 3 includes a cylinder body 19 and several sets of electric heating plates 20 installed inside the cylinder body 19. The sets of electric heating plates 20 have an arc-shaped structure and are embedded in the inner wall of the cylinder body 19. The electric heating plates 20 are energized to heat and dry the slag inside.

[0020] Further improvements, such as Figure 2 As shown, the arc-shaped liquid collection hood 11 has an overall arc-shaped structure and closed structures at both ends. The bottom of the arc-shaped liquid collection hood 11 is connected to the drainage pipe 12, which can collect and treat the seeping liquid.

[0021] Further improvements, such as Figure 3 As shown, the water-cooled pipe 17 includes an outer pipe 21, a water inlet pipe 22, a water outlet pipe 23, and a drain pipe 24. The outer pipe 21 is fitted onto the air intake pipe 16. The water inlet pipe 22 is located inside the outer pipe 21 and its two ends are connected to the water inlet pipe 23 and the drain pipe 24, respectively. The water inlet pipe 23 introduces cold water into the water inlet pipe 22, and the steam in the air intake pipe 16 is rapidly cooled through the water inlet pipe 22.

[0022] Specifically, the drainage pipe 12 has a spiral structure and is laid on the surface of the air intake pipe 16. This design facilitates the cooling and liquefaction of the steam in the air intake pipe 16 by the cold water in the drainage pipe 12.

[0023] In use: Before the slag is introduced into the slag cooler, the slag is introduced into the heated feed pipe 3 through the slag guide pipe 2. The electric heating plate 20 is energized to heat and dry the slag inside. At the same time, the drive motor 4 drives the rotating rod 5 to rotate. During the rotation of the rotating rod 5, the spiral blades 6 rotate synchronously. The spiral blades 6 guide the slag towards the slag inlet box at the end of the slag cooler body 1. Meanwhile, the liquid seeping down from the slag is introduced into the arc-shaped liquid collection hood 11 and into the liquid storage container 13. The steam generated by heating is guided by the induced draft fan 15 and introduced into the air intake pipe 16. The water inlet pipe 23 introduces cold water into the water intake pipe 22. The water intake pipe 22 quickly cools the steam in the air intake pipe 16. The liquefied water is guided along the connecting pipe 18 into the liquid storage container 13, thus completing the purpose of collecting the water in the slag.
