Description

Technical Field

[0001] The utility model relates to the technical field of waste heat boilers, and particularly relates to a cleaning tool for caking of waste heat boilers. Background Art

[0002] The flue gas generated after the zinc concentrate is roasted in the fluidized bed roaster first passes through the waste heat boiler for cooling and dust removal. The flue gas contains metal oxides. A large amount of molten metal oxides such as copper, lead, and zinc are cooled to form dense, hard, and high-strength ash deposits when they encounter the cooling surfaces (water walls, slag-removing tube screens, convection tube bundles) of the waste heat boiler. The enrichment of the ash deposits to form caking not only causes the heat exchange efficiency of the waste heat boiler to decrease, the evaporation capacity to drop, and the flue gas temperature to rise, but also the large-area shedding affects the normal operation of subsequent facilities and even affects the stability of the entire production system. Therefore, it is necessary to regularly clean the ash in the waste heat boiler.

[0003] At present, most of the ash cleaning is carried out by combining two methods: blasting ash cleaning and elastic mechanical vibration ash cleaning. However, there are still some cakings (large cakings) that fall off and get stuck on the grizzly screen at the top of the boiler scraper conveyor and cannot be discharged normally. As a result, the grizzly screen at the top of the boiler scraper conveyor is severely clogged with ash, and it is difficult to clean the cakings on the grizzly screen. When using a galvanized elbow and a steel bar for cleaning, it is easy to get stuck on the grizzly screen, and the safety is relatively poor. The lack of a dedicated cleaning tool increases the labor intensity of workers, the cleaning efficiency of the boiler cakings is low, and the long-term reduction of air volume and material affects the stable operation of the production system.

[0028] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0029] As shown Figures 1 to 3 in the figure, a cleaning tool for removing caking in a waste heat boiler includes a handle sleeve 1, a connecting rod 2, and a cleaning plate 3. In this embodiment, the handle sleeve 1 is made of a galvanized pipe with a length of 30 cm (centimeters), the connecting rod 2 is made of a galvanized pipe with a length of 3 m (meters), and the cleaning plate 3 is made of a high-temperature resistant steel plate with a thickness of 6 mm (millimeters), a length of 45 cm, and a width of 20 cm. Generally, the size of the cleaning plate 3 is designed to be slightly larger than the size of the grid screen. The connecting rod 2 has a curvature. One end of the connecting rod 2 is fixedly connected to the handle sleeve 1, and the other end is rotatably connected to the cleaning plate 3. The cleaning tool further includes a first arc-shaped rod 4 and a second arc-shaped rod 5 that are rotatably connected. One end of the first arc-shaped rod 4 away from the second arc-shaped rod 5 is rotatably connected to the cleaning plate 3. One end of the second arc-shaped rod 4 away from the first arc-shaped rod 4 is detachably connected to the connecting rod 2. A plurality of slots 21 are provided on the connecting rod 2. One end of the second arc-shaped rod 5 away from the first arc-shaped rod 4 is snapped into one of the slots 21. In the waste heat boiler used in this embodiment, the water wall of the waste heat boiler is located at the lowermost side and above the boiler scraper conveyor. The outer side wall of the water wall is inclined, and the grid screen is located between the outer side walls of two adjacent water walls. There are still some cakings (large cakings) that fall off and get stuck on the grid screen at the top of the boiler scraper conveyor because small cakings can pass through the grid openings of the grid screen and fall onto the chain plate of the conveyor, and the chain plate conveys the small cakings; but the large cakings fall on the grid screen. It should be noted that the curvature of the connecting rod 2 in this embodiment is designed to be 60°, but it is not limited to this. The curvature of the connecting rod 2 can be adjusted according to the inclination of the water wall of the waste heat boiler to be cleaned.

[0030] The cleaning tool can be used to check the amount of large cakings falling on the grid screen. When there are too many large cakings on the grid screen, cleaning is carried out. A person holds the cleaning tool in this embodiment to clean the large cakings on the grid screen. Specifically, a person holds the handle sleeve 1. Since the connecting rod 2 has a curvature, the connecting rod 2 and the cleaning plate 3 can be inserted into the grid screen from the cleaning opening on the waste heat boiler and enter above the grid screen. The curved part of the connecting rod 2 will contact the outer side wall of the water wall at this time, and the outer side wall of the water wall plays a supporting role for the connecting rod 2. When a person is operating, the connecting rod 2 will not cause the other end of the connecting rod 2 and the cleaning plate 3 to shake or sway due to its own excessive length; when the cleaning plate 3 hooks the large cakings on the grid screen onto it, the person then extends the connecting rod 2 and the cleaning plate 3 out of the cleaning opening, thereby realizing the cleaning of the large cakings on the grid screen.

[0031] And take out the end of the second arc rod 5 far from the first arc rod 4 from a slot 21, then the cleaning plate 3 can rotate. After adjusting the angle of the cleaning plate 3 according to the cleaning requirements, rotate the first arc rod 4 and the second arc rod 5, and then snap the end of the second arc rod 5 far from the first arc rod 4 into a slot 21 again. The cleaning plate 3 is fixed and no longer rotates, and the cleaning plate 3 is adjusted to different angles to better hook the large lumps on the grid sieve onto it.

[0032] The cleaning tool of this embodiment has a simple structure and convenient operation. It can clean the large lumps on the grid sieve in a timely and convenient manner, reduce the labor intensity of people, improve the cleaning efficiency when people use it to clean the large lumps, and at the same time, it will not get stuck on the grid sieve, improving the operation safety.
