Description

Technical Field

[0001] This utility model relates to the field of active lime processing technology, and in particular to a dust removal device for an active lime rotary kiln. Background Technology

[0002] A rotary kiln for quicklime is a specialized device for calcining limestone, also known as a lime kiln. It is widely used in the steel industry and other industrial sectors that require high-quality quicklime. By utilizing fuels such as blast furnace gas and coke oven gas, high-quality quicklime can be produced, improving the strength of steel and the quality of other related products. During the production process, lime kilns generate a large amount of dust. If not treated in time, this dust will float into the air and affect air quality.

[0003] Chinese patent disclosure relates to a dust removal device for lime kilns (publication number CN214552235U). This patented technology uses a filter screen, an electric telescopic rod, and a scraper. The telescopic rod extends and retracts, allowing the scraper to remove dust from the surface of the filter screen, effectively preventing dust accumulation and clogging. However, the scraper can only clean the dust on the surface of the filter screen, while dust accumulates inside the filter screen. Moreover, the scraper's prolonged contact with the filter screen surface can easily damage the filter screen and affect the filtration effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dust removal device for a rotary kiln for quicklime, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for a rotary kiln for quicklime, comprising:

[0006] The dust collector has seven fixing rings connected to the upper and lower sides of its inner wall. A stainless steel water pipe is connected inside the fixing ring. Several spray holes are opened on the outside of the stainless steel water pipe. One end of the stainless steel water pipe passes through the outside of the dust collector and is equipped with a water supply mechanism.

[0007] A frame is connected to the right side of the dust collector, and a sealing ring is fixedly connected to the front side of the frame. A pair of first positioning mechanisms are connected to the upper and lower sides of the frame. An outer shell is connected to the outer side of the frame through the first positioning mechanisms. A first filter screen is connected to the front side of the outer shell. A second positioning mechanism is provided on the inner wall of the outer shell, and a second filter screen is connected to the inner wall of the outer shell through the second positioning mechanism.

[0008] As a further technical solution of this utility model, the second positioning mechanism includes a slide and a concave base. Both the slide and the concave base are fixedly connected to the inner wall of the outer shell. The slide is located above the concave base. The bottom of the second filter screen is embedded in the groove at the top of the concave base. A pair of sliders are slidably connected inside the slide. A limiting plate is fixedly connected below the sliders. The limiting plate is sleeved on the end of the second filter screen. A protrusion is connected to the outside of the limiting plate.

[0009] As a further technical solution of this utility model, the first positioning mechanism includes a U-shaped plate, with through holes on both sides of the U-shaped plate. A rod is slidably connected inside the through hole. One end of the rod is connected to a pull ring, and the other end of the rod is connected to a hook. The end of the hook is fixedly connected to the outer shell.

[0010] As a further technical solution of this utility model, the top end of the hook is provided with an insertion hole, and the other end of the insertion rod extends into the interior of the insertion hole.

[0011] As a further technical solution of this utility model, a return spring is sleeved on the outside of the insertion rod and inside the U-shaped plate. One end of the return spring is fixedly connected to the U-shaped plate, and the other end of the return spring is fixedly connected to a ring. The inner side of the ring is fixedly connected to the insertion rod.

[0012] As a further technical solution of this utility model, the water supply mechanism includes a water pump and a water tank. Both sides of the water pump are connected to hoses. One end of the hose penetrates the interior of the water tank, and the other end of the hose is fixedly connected to a stainless steel water pipe.

[0013] This utility model provides a dust removal device for a rotary kiln for quicklime, which has the following advantages compared with the prior art:

[0014] 1. This design provides a dust removal device for a rotary kiln used for quicklime. By setting up a first filter screen and a second filter screen, the filtration effect is improved. When the second filter screen becomes clogged or damaged, the insert rod can be removed from the hook by pulling the pull rings on both sides outward, allowing the outer shell to be removed. Then, the limiting plates on both sides can be slid outward, making it convenient to remove the second filter screen from the inner wall of the outer shell for cleaning and replacement without removing it. This solves the problems of scrapers not cleaning the dust thoroughly and scrapers easily damaging the filter screen, greatly improving the dust removal effect.

[0015] 2. The dust removal device for a rotary kiln for quicklime designed in this paper introduces water from the water tank into a stainless steel water pipe through a hose by turning on the water pump, and then sprays it out through multiple nozzles. This helps to cool and adsorb the high-temperature dust in the dust removal box, prevents the high-temperature dust from contacting the filter screen, reduces the damage to the filter screen, and improves the service life of the filter screen.

[0026] A frame 5 is connected to the right side of the dust collection box 1. A sealing ring 24 is fixedly connected to the front side of the frame 5. A pair of first positioning mechanisms are connected to the upper and lower sides of the frame 5. The outer side of the frame 5 is connected to the outer shell 6 through the first positioning mechanism. A first filter 7 is connected to the front side of the outer shell 6. A second positioning mechanism is provided on the inner wall of the outer shell 6. A second filter 14 is connected to the inner wall of the outer shell 6 through the second positioning mechanism.

[0027] like Figures 3 to 7 As shown, the second positioning mechanism includes a slide 19 and a concave base 15. Both the slide 19 and the concave base 15 are fixedly connected to the inner wall of the outer casing 6. The slide 19 is located above the concave base 15. The bottom of the second filter screen 14 is embedded in the groove at the top of the concave base 15. A pair of sliders 22 are slidably connected inside the slide 19. A limiting plate 21 is fixedly connected below the sliders 22. The limiting plate 21 is sleeved on the end of the second filter screen 14. A protrusion 20 is connected to the outside of the limiting plate 21. Sliding the limiting plates 21 on both sides outwards makes it convenient to clean and replace the second filter screen 14 without removing it from the inner wall of the outer casing 6.

[0028] like Figures 3 to 7 As shown, the first positioning mechanism includes a U-shaped plate 12. Both sides of the U-shaped plate 12 have through holes 23. A rod 17 is slidably connected inside the through holes 23. One end of the rod 17 is connected to a pull ring 13, and the other end of the rod 17 is connected to a hook 8.
