Description
Technical Field
[0001] This utility model relates to the technical field of boiler slag cooler, and in particular to a boiler slag cooler that prevents slag spraying and splashing. Background Technology
[0002] A boiler slag cooler, also known as a slag remover, is a device used to process high-temperature boiler slag. Its working principle is to reduce the temperature of the slag through water cooling heat exchange, providing a safe working environment for slag removal and thus helping the boiler to operate normally.
[0003] However, due to the large weight of concentrated slag, it is easy to generate great pressure during slag discharge. Most of the existing boiler slag coolers on the market are not good at relieving the pressure generated by the slag during slag discharge, which can easily lead to slag spraying and splashing, resulting in poor safety.
[0004] Therefore, those skilled in the art have provided a boiler slag cooler to prevent slag spraying and splashing, in order to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a boiler slag cooler that prevents slag spraying and splashing. The tank is divided into upper and lower layers by a partition plate in the slag discharge mechanism. The movement of the insert plate changes the opening and closing of the slag discharge port and slag discharge pipe, thereby controlling the slag discharge rate. At the same time, the inclined plate of the opening slows down the rate of slag descent, preventing slag spraying and splashing and improving the safety of slag discharge.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A boiler slag cooler for preventing slag spraying includes a tank, a rotating tube, and two insert plates. A cooling mechanism is provided at the upper end of the tank. The cooling mechanism includes an upper rotating tube, a driven gear, and a lower rotating tube. A rotating cavity is opened inside the upper rotating tube. A servo motor is provided on one side of the top surface inside the rotating cavity. The output shaft of the servo motor is fixedly connected to a drive gear. The drive gear meshes with the driven gear. The inner wall of the driven gear is fixedly connected to the rotating tube. Upper blades are fixedly connected to all four sides of the upper end of the outer wall of the rotating tube. The upper blades are all provided with cooling channels, which are all connected to the rotating tube. The upper end of the tank body is provided with a cooling pipe, and the lower end of the tank body is provided with a slag discharge mechanism. The slag discharge mechanism includes a partition plate and multiple open inclined plates. The middle part of the inner wall of the tank body is fixedly connected to the partition plate. A slag discharge port is provided on one side of the upper end of the partition plate. The middle and lower ends of the outer wall of one side of the tank body are fixedly connected with an electric telescopic rod. The other side of the electric telescopic rod is fixedly connected to an insert plate. The above technical solution divides the tank into upper and lower layers using a partition plate. Two electric telescopic rods each drive an insert plate, and the movement of the insert plate changes the opening and closing of the slag discharge port and slag discharge pipe, facilitating control of the slag discharge rate. At the same time, the inclined plate at the opening slows down the rate of slag descent, preventing slag spray and splashing, thus improving safety. In addition, the slag on the outer layer inside the tank is cooled by a cooling pipe, while cooling water is introduced from the rotating pipe through a cooling channel to cool the slag on the inner layer inside the tank. Meanwhile, a servo motor is used as a power source to stir the slag with the upper blades, making the slag flow and further improving the slag cooling efficiency.
[0007] Furthermore, support frames are provided at the four corners of the lower end of the tank, and a control panel is provided at the front end of the support frame. A slag inlet pipe is connected through the other side of the upper end of the tank. The above technical solution improves the stability of the device during operation by fixing the support frame at the lower end of the tank, while also maintaining a certain height between the device and the ground, which facilitates the slag discharge operation for the staff. The slag inlet pipe, which runs through the upper end of the tank, is fixed to the boiler's slag discharge channel with multiple bolts and nuts, allowing the slag to enter the tank.
[0008] Furthermore, the upper middle part of the tank body is connected to the upper transfer pipe, both sides of the cooling pipe extend out of the tank body, and the lower middle part of the tank body is connected to the lower transfer pipe. Through the above technical solution, by connecting the tank body with the upper and lower transfer pipes, the rotating pipe can be inserted into the upper and lower transfer pipes, allowing the upper transfer pipe, rotating pipe, cooling channel and lower transfer pipe to communicate. The upper transfer pipe can be connected to the external water inlet pipe, and the lower transfer pipe can be connected to the external drainage pipe.
[0009] Furthermore, a slag discharge pipe is connected through one side of the lower end of the tank, and the insert plates all penetrate the tank and lead to the slag discharge port and the slag discharge pipe respectively. The above technical solution allows the electric telescopic rod to act on the baffle plate, which can change the degree of obstruction of the baffle plate on the slag discharge port and the slag discharge pipe, thereby controlling the slag discharge rate. When the baffle plate seals the slag discharge port, the slag above the partition plate can be cooled in the tank. At this time, the slag discharge pipe can be opened to allow the cooled slag to be discharged.
[0010] Furthermore, the lower end of the rotating tube passes through the partition plate and the opening inclined plate in sequence to the interior of the lower rotating tube, and multiple lower blades are fixedly connected to the lower end of the outer wall of the rotating tube; Through the above technical solution, the rotating tube passes through the partition plate and the opening inclined plate, allowing the rotating tube to rotate and drive the upper and lower blades fixedly connected to it to move inside the tank. The upper blade can stir the slag above the partition plate, while the lower blade is located between the opening inclined plates and can push the slag along the opening inclined plates to avoid accumulation.
[0011] Furthermore, an upper sealing ring is fixedly connected to the middle of the inner wall of the upper transfer pipe, and the inner wall of the upper sealing ring is tightly fitted with the rotating pipe; a lower sealing ring is fixedly connected to the middle of the inner wall of the lower transfer pipe, and the inner wall of the lower sealing ring is tightly fitted with the rotating pipe. The above technical solution improves the sealing performance between the rotating pipe and the upper and lower connecting pipes by ensuring that the upper and lower sealing rings are tightly fitted to the rotating pipe and preventing cooling water leakage.
[0012] Furthermore, an upper bearing is fixedly connected to the lower end of the inner wall of the upper transfer pipe, and the inner wall of the upper bearing is fixedly connected to the rotating pipe; a lower bearing is fixedly connected to the upper end of the inner wall of the lower transfer pipe, and the inner wall of the lower bearing is fixedly connected to the rotating pipe. The above technical solution involves fixing the outer walls of the upper and lower bearings to the upper and lower transfer tubes, while fixing the inner walls of the upper and lower bearings to the rotating tube, thus enabling the rotating tube to rotate stably within the upper and lower transfer tubes.
[0013] This utility model has the following beneficial effects: 1. This utility model proposes a boiler slag cooler to prevent slag spraying and splashing. The tank is divided into upper and lower layers by a partition plate in the slag discharge mechanism. Two electric telescopic rods each drive an insert plate. The movement of the insert plates changes the opening and closing of the slag discharge port and slag discharge pipe, which facilitates the control of the slag discharge rate. At the same time, the opening inclined plate fixedly connected inside the tank slows down the rate of slag descent, avoiding the rapid discharge of a large amount of slag. This helps to relieve the pressure generated by the slag during slag discharge, avoids slag spraying and splashing, and improves safety.
[0014] 2. The boiler slag cooler proposed in this utility model prevents slag spraying and splashing. The cooling mechanism uses cooling pipes to cool the outer layer of slag inside the tank. In conjunction with the cooling channels inside the blades, cooling water is introduced from the rotating pipe to cool the inner layer of slag inside the tank. At the same time, a servo motor drives the drive gear, which, through the driven gear, drives the upper blades to stir the slag, making the slag flow and thus improving the cooling efficiency of the slag.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Reference Figure 1-5 This utility model provides a specific implementation method: A boiler slag cooler for preventing slag spraying includes a tank 1, a rotating tube 505, and two insert plates 604. A cooling mechanism 5 is provided at the upper end of the tank 1. The cooling mechanism 5 includes an upper rotating tube 501, a driven gear 506, and a lower rotating tube 510. A rotating cavity 502 is opened inside the upper rotating tube 501. A servo motor 503 is provided on one side of the top surface inside the rotating cavity 502. The output shaft of the servo motor 503 is fixedly connected to a drive gear 504. The drive gear 504 meshes with the driven gear 506. The inner wall of the driven gear 506 is fixedly connected to the rotating tube 505. Upper blades 507 are fixedly connected to all four sides of the upper end of the outer wall of the rotating tube 505. Cooling channels 508 are provided inside the upper blades 507, and the cooling channels 508 are all connected to the rotating tubes 505. Cooling pipes 509 are provided at the upper end of the tank body 1, and slag discharge mechanism 6 is provided at the lower end of the tank body 1. The slag discharge mechanism 6 includes a partition plate 601 and multiple open inclined plates 605. The middle part of the inner wall of the tank body 1 is fixedly connected to the partition plate 601. A slag discharge port 602 is provided on one side of the upper end of the partition plate 601. Electric telescopic rods 603 are fixedly connected to the middle and lower ends of one side of the outer wall of the tank body 1. The other side of the electric telescopic rods 603 is fixedly connected to the insert plate 604.
[0019] The tank body 1 is divided into upper and lower layers by the partition plate 601 in the slag discharge mechanism 6. Two electric telescopic rods 603 each drive an insert plate 604. The movement of the insert plate 604 changes the opening and closing of the slag discharge port 602 and the slag discharge pipe 606, which facilitates the control of the slag discharge rate. At the same time, the opening inclined plate 605 fixedly connected inside the tank body 1 slows down the rate of slag descent, avoiding the rapid discharge of a large amount of slag. This helps to relieve the pressure generated by the slag during slag discharge, avoids slag spraying and splashing, and improves safety. In addition, the cooling pipe 509 in the cooling mechanism 5 cools the outer layer of slag inside the tank body 1. The cooling channel 508 inside the blade 507 introduces cooling water from the rotating pipe 505 to cool the inner layer of slag inside the tank body 1. At the same time, the servo motor 503 drives the drive gear 504, which is transmitted through the driven gear 506. The rotating pipe 505 drives the upper blade 507 to stir the slag, making the slag flow and thus improving the slag cooling efficiency.
[0020] Support frames 2 are installed at the four corners of the lower end of tank 1. A control panel 3 is installed at the front end of the support frame 2. A slag inlet pipe 4 is connected through the other side of the upper end of tank 1. The support frames 2 fixedly connected to the lower end of tank 1 improve the stability of the device during operation and also keep the device at a certain height from the ground, which facilitates the slag discharge operation. The slag inlet pipe 4 connected through the upper end of tank 1 is fixed to the slag discharge channel of the boiler with multiple bolts and nuts, allowing the slag to enter the interior of tank 1. The middle of the upper end of tank 1 is connected through the upper transfer pipe 501. The cooling pipe 509 extends through tank 1 on both sides. The middle of the lower end of tank 1 is connected through the lower transfer pipe 510. The connection between tank 1 and the upper transfer pipe 501 and the lower transfer pipe 510... The connection allows the rotating pipe 505 to be inserted into the upper rotating pipe 501 and the lower rotating pipe 510, enabling communication between the upper rotating pipe 501, the rotating pipe 505, the cooling channel 508, and the lower rotating pipe 510. The upper rotating pipe 501 can be connected to an external water inlet pipe, while the lower rotating pipe 510 can be connected to an external drainage pipe. A slag discharge pipe 606 is connected through one side of the lower end of the tank body 1. Insert plates 604 penetrate the tank body 1 and extend to the slag discharge port 602 and the slag discharge pipe 606 respectively. An electric telescopic rod 603 acts on the insert plates 604, changing the degree of obstruction of the slag discharge port 602 and the slag discharge pipe 606, thereby controlling the slag discharge rate. When the insert plates 604 seal the slag discharge port 602, the slag discharge rate can be controlled by the partition plate 601. The slag is cooled inside the tank 1. During this process, the slag discharge pipe 606 can be opened to allow the cooled slag to be discharged. The lower end of the rotating pipe 505 passes through the partition plate 601 and the opening inclined plate 605 to the interior of the lower transfer pipe 510. Multiple lower blades 11 are fixedly connected to the lower end of the outer wall of the rotating pipe 505. The rotating pipe 505, passing through the partition plate 601 and the opening inclined plate 605, allows it to rotate, driving the upper blades 507 and lower blades 11 fixedly connected to it to move inside the tank 1. The upper blades 507 can stir the slag above the partition plate 601, while the lower blades 11, located between the opening inclined plates 605, can push the slag along the opening inclined plates 605 to prevent accumulation. The inner wall of the upper transfer pipe 501... An upper sealing ring 7 is fixedly connected to the middle of the upper connecting pipe 501, and the inner wall of the upper sealing ring 7 is tightly fitted to the rotating pipe 505. A lower sealing ring 8 is fixedly connected to the middle of the inner wall of the lower connecting pipe 510, and the inner wall of the lower sealing ring 8 is tightly fitted to the rotating pipe 505. By ensuring that the upper sealing ring 7 and the lower sealing ring 8 fixedly connected to the upper connecting pipe 501 and the lower connecting pipe 510 are tightly fitted to the rotating pipe 505, the sealing performance between the rotating pipe 505 and the upper and lower connecting pipes 501 and 510 is improved, preventing cooling water leakage. An upper bearing 9 is fixedly connected to the lower end of the inner wall of the upper connecting pipe 501, and the inner wall of the upper bearing 9 is fixedly connected to the rotating pipe 505. A lower bearing 10 is fixedly connected to the upper end of the inner wall of the lower connecting pipe 510, and the inner wall of the lower bearing 10 is fixedly connected to the rotating pipe 505.The upper bearing 9 and the lower bearing 10 are fixedly connected to the upper connecting pipe 501 and the lower connecting pipe 510 via their outer walls, while the inner walls of the upper bearing 9 and the lower bearing 10 are fixedly connected to the rotating pipe 505, allowing the rotating pipe 505 to rotate stably within the upper connecting pipe 501 and the lower connecting pipe 510.
[0021] Working principle: When using this boiler slag cooler to prevent slag spraying, the operator first connects the slag inlet pipe 4 to the boiler's slag discharge channel using bolts and nuts. Then, the upper transfer pipe 501 is connected to the external water inlet pipe, and the lower transfer pipe 510 is connected to the external drainage pipe. Next, the cooling pipe 509 is connected to the external water inlet and outlet pipes. The slag entering the tank 1 accumulates above the partition plate 601. The operator then uses the control panel 3 to start the servo motor 503, causing the rotating pipe 505 to drive the upper blade 507 to rotate. The slag is stirred, and the cooling pipe 509 is used to cool the outer layer of slag inside the tank 1. The cooling channel 508 inside the upper blade 507 introduces cooling water from the rotating pipe 505 to cool the inner layer of slag inside the tank 1. Finally, the operator uses the control panel 3 to control the electric telescopic rod 603 to open the slag discharge port 602 and the insert plate 604 inside the slag discharge pipe 606, so that the cooled slag falls onto the opening inclined plate 605, which slows down the rate of slag descent and avoids a large amount of slag being discharged quickly and concentrated, thus preventing slag spraying and splashing.
