Description

Technical Field

[0001] The utility model relates to the technical field of boiler slag poking, in particular to a slag poking device for a boiler slag discharge pipe. Background Art

[0002] During the operation of the boiler, as coal powder is continuously fed into the furnace for combustion, slag will continue to be produced. More slag will affect the thickness of the material layer, causing a smaller air volume and the risk of furnace collapse. The slag pipe discharges part of the slag when the material layer becomes thicker and the air volume becomes smaller, so that the material layer thickness is moderate.

[0003] The boiler slag outlet has high and low temperatures and poor fluidization, which leads to coking at the slag outlet or unsmooth slag discharge. Coking at the slag outlet is a common problem of boilers. During normal operation, operators need to wear anti-scalding clothes and use tools such as steel bars to poke through the slag. The operation is difficult and the hot slag that is poked out also poses a safety hazard of burns. Utility Model Content

[0015] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-2As shown, a slag poking device for a boiler slag discharge pipe comprises a movable material receiving frame 1, a through slot is provided in the middle of the material receiving frame 1, a shroud 2 is provided inside the material receiving frame 1 and on the upper surface of the through slot, an extension frame 3 is slidably connected inside the material receiving frame 1, bottom plates 4 are provided at the bottom of both sides of the material receiving frame 1, a first electric telescopic device 5 is provided on the bottom plate 4, extension plates 6 are provided on both sides of the upper end of the extension frame 3, an output end of the first electric telescopic device 5 is fixedly connected to the extension plate 6, a sleeve 7 is slidably connected inside the shroud 2, a second electric telescopic device 8 is provided inside the sleeve 7, a material guide plate 9 is provided on the upper surface of the sleeve 7, and a guide plate 9 is provided on the upper surface of the sleeve 7. Both ends of the material plate 9 are fixedly connected to the extension frame 3 respectively, a through groove is arranged in the middle of the material guide plate 9, the output end of the second electric telescopic device 8 is slidably connected to the through groove, and a slag poking rod 10 is arranged at the output end of the second electric telescopic device 8. A mounting groove is opened in the middle of the slag poking rod 10, and scraping rods 11 are arranged on both sides of the inner side of the mounting groove respectively. The upper end of the scraping rod 11 is hinged to the slag poking rod 10, and also includes a V-shaped spring 12 arranged in the mounting groove, the V-shaped spring 12 is fixedly connected to the slag poking rod 10, the V-shaped spring 12 has two movable connecting ends, and the two scraping rods 11 are fixedly connected to one of the connecting ends of the V-shaped spring 12 respectively.

[0017] The receiving frame 1 is used to receive the slag, and the guide plate 9 is an inverted V-shape. The guide plate 9 is arranged in the middle position of the receiving frame 1. When receiving the slag through the receiving frame 1, it is necessary to move the receiving frame 1 to the position of the slag discharge port, and move the guide plate 9 to be directly below the slag discharge port. When the slag falls downward through the slag discharge port, the slag is separated by the guide plate 9, and part of the slag enters one side of the guide plate 9, and the other part of the slag enters the other side of the guide plate 9. The guide plate 9 can prevent the slag in the receiving frame 1 from accumulating too high and overflowing from the receiving frame 1. When receiving the slag, the staff does not need to level the slag in the receiving frame 1, thereby improving the convenience of the receiving frame 1 in receiving the slag.

[0018] When the slag in the slag discharge port is blocked by slag, the second electric telescopic device 8 is controlled to start, the output end of the second electric telescopic device 8 extends, and drives the slag poking rod 10 to enter the inside of the slag discharge port. When the slag poking rod 10 enters the inside of the slag discharge port, the slag in the slag discharge port will squeeze the scraper rod 11 in the slag poking rod 10, and make the scraper rod 11 move into the installation groove of the slag poking rod 10, thereby reducing the difficulty of the slag poking rod 10 entering the slag discharge port. When the output end of the second electric telescopic device 8 retracts, the slag poking rod 10 is driven 10 moves downward, at this time, the resistance between the scraper rod 11 and the slag in the slag discharge port is relatively large, which will prompt the scraper rod 11 to move to the outside of the mounting groove, and the opening angle between the two scraper rods 11 is increased, so that the slag rod 10 can effectively scrape the blockage in the slag discharge port downward from the slag discharge port through the two scraper rods 11, so that the blockage of the slag discharge port is alleviated. At the same time, the opening angle of the V-shaped spring 12 is limited. When the two scraper rods 11 move downward, the maximum opening angle between the two scraper rods 11 is less than 180°.

[0019] When the position of the slag discharge port is higher, by controlling the output ends of the two first electric telescopic devices 5 to extend, the extension frame 3 is driven to move upward in the material receiving frame 1, thereby improving the material receiving capacity of the material receiving frame 1 and driving the sleeve 7 and the second electric telescopic device 8 to move upward, so that the distance between the slag poking rod 10 and the slag discharge port is shortened, making it easier for the slag poking rod 10 to be inserted into the slag discharge port to a sufficient length, thereby facilitating the effective unblocking of the blocked slag discharge port.

[0020] Furthermore, the top of the slag-poking rod 10 is configured to be conical, so that the slag-poking rod 10 can be more conveniently inserted into the slag blocking the slag outlet when moving upward.

[0021] Furthermore, a moving wheel 13 is provided at the lower end of the receiving frame 1 .

[0022] Furthermore, a handle 14 is provided on one side of the material receiving frame 1 .

[0023] Furthermore, the scraper rod 11 can completely enter the installation groove on the slag poking rod 10. When the slag poking rod 10 moves upward, the scraper rod 11 can be completely retracted into the inside of the slag poking rod 10, thereby reducing the resistance between the slag poking rod 10 and the slag in the slag discharge port.

[0024] When the device is in use, the staff only needs to move the material receiving frame 1 to the bottom of the slag discharge port. The slag poking and material receiving do not require the operator to operate close to the slag discharge port. The operator can remotely control the start of the first electric telescopic device 5, and the scraper rod 11 that can be set can quickly, stably and efficiently clear the slag blocked in the slag discharge port, thereby improving the convenience and safety of clearing the slag discharge port and reducing potential risks.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
