[0002] When the smelting dust removal system is working, the industrial dust is collected into the dust box through the flue, and the dust is removed by the dust bags in the dust box. Under the filtering effect of the dust bags, the dust is intercepted and falls to the bottom of the dust box under the action of its own gravity, and gathers at the trumpet collection port at the bottom of the dust box. Finally, the dust is collected and processed through the recovery bucket connected to the lower end of the trumpet collection port.

[0003] At present, the trumpet collection port at the bottom of the dust box is usually connected to the recycling bin by direct connection or soft connection. The above connection method will cause the process of dust falling into the recycling bin to be uncontrolled. The dust collected by the trumpet collection port will often gather to a certain extent and then fall into the recycling bin in large quantities, causing serious dust and the risk of dust fire and explosion; at the same time, a large amount of dust accumulates at the trumpet collection port, which is very likely to cause the trumpet collection port to be blocked, resulting in incomplete dust cleaning and affecting the normal operation of the dust removal system.

Specific Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] As Figure 1-2 shown, an auxiliary ash-dropping device for a dust removal system includes a box body 1. An ash inlet 11 is provided at the upper end of the box body 1 for communicating with the horn-shaped collection port at the bottom of the dust collection box 7. A dust outlet 12 is provided at the lower end of the box body 1 for communicating with the recycling bucket 2. A rotary scraper assembly 3 is provided in the box body 1 corresponding to the ash inlet 11. The rotary scraper assembly 3 includes a rotating shaft 31 rotatably connected in the box body 1. A plurality of scrapers 32 are evenly distributed along the radial direction of the rotating shaft 31. The scrapers 32 can rotate in the box body 1 driven by the rotating shaft 31.

[0022] During use, the dust collected by the horn-shaped collection port of the dust collection box 7 enters the box body 1 through the ash inlet 11 of the box body 1, lands on the slowly rotating scraper 32, and moves circumferentially synchronously with the scraper 32. When the scraper 32 rotates to a downward-sloping position, the dust on the scraper 32 will gradually slide down due to gravity and finally fall into the recycling bucket 2 to complete the dust recycling. In this embodiment, the process of dust falling is intervened by the rotary scraper assembly 3. The falling dust first contacts the scraper 32 and then is slowly released to the recycling bucket 2 by the scraper 32, improving the strong dust emission caused by the direct fall of dust from the horn-shaped collection port of the dust collection box 7 into the recycling bucket 2 and reducing the risk of dust fire and explosion.

[0023] As a preferred embodiment, the outer edge of the scraper 32 in the height direction is higher than the ash inlet 11 of the box body 1, so that the scraper 32 can extend to a certain depth into the horn-shaped collection port of the dust collection box 7 to scrape the dust accumulated in the horn-shaped collection port of the dust collection box 7, avoiding the situation where a large amount of dust accumulates and falls concentratedly at the horn-shaped collection port. At the same time, the problem of blockage of the horn-shaped collection port is eliminated, realizing the orderly and controllable recycling of dust in the dust collection box 7 and ensuring the stable operation of the dust removal system.

[0024] Preferably, the rotating shaft 31 is connected to a power device 4 to obtain the rotational power of the rotary scraper assembly 3, realizing the continuous and stable auxiliary ash discharge of the rotary scraper assembly 3.

[0025] Preferably, a vibrator 5 is provided on the box body 1 to facilitate ash discharge. The vibrator 5 can have an oscillating ash discharge effect on the dust adhering to the inner wall of the box body 1 and the scraper 32. At the same time, it also plays a positive role in the smooth ash dropping of the collection box, improving the cleanliness of dust cleaning.

[0026] An insertion plate valve assembly 6 is provided at the upper end of the ash inlet 11 corresponding to the horn-shaped collection port of the dust collection box 7, as Figure 2As shown, the plug valve assembly 6 includes a rectangular frame 61. A chute 62 is formed in the rectangular frame 61. A sliding plate 63 is slidably connected in the chute 62. The opening and closing action of the ash inlet 11 of the box body is realized by the displacement of the sliding plate 63 in the chute 62 of the rectangular frame 61. When it is necessary to clean the recycling bin 2 or perform equipment inspection, repair and maintenance, the sliding plate 63 can be slid to temporarily close the ash inlet 11 of the box body, which facilitates the cleaning of the recycling bin 2 and the equipment inspection, repair and maintenance operations.

[0027] Preferably, in order to facilitate the sliding operation of the sliding plate 63, a push-pull rod 64 is connected to the sliding plate 63. One end of the push-pull rod 64 is fixedly connected to the sliding plate 63, and the other end penetrates through the rectangular frame 61 and is slidably connected to the rectangular frame 61. During use, hold the push-pull rod 64 and drive the sliding plate 63 to slide in the chute 62 to complete the opening and closing action of the ash inlet 11.
