Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, in particular to a device for spraying calcium chloride on sintered ore. Background Art

[0002] In the process of steel smelting, the blast furnace uses sintered ore sprayed with CaCl2 solution, which can reduce the low-temperature reduction and pulverization of the upper furnace charge of the blast furnace, improve the air permeability of the material column, and promote the smooth operation of the furnace. In the use of the existing calcium chloride spraying device, the water flow sprayed from the nozzle is directly sprayed onto the sintered ore on the surface of the conveyor belt. Due to the large impact force of the water flow, the sintered ore is easily flushed away. In addition, the sintered ore cannot be turned over during the spraying process, so that only one surface of the sintered ore is sprayed, resulting in uneven spraying. In this regard, the utility model provides a sintered ore spraying calcium chloride device to overcome this technical problem. Utility Model Content

[0006] Furthermore, the cover shell is provided with material passing holes on both the front and rear sides, and the material passing holes are correspondingly located on the conveyor belt.

[0007] Furthermore, the inner wall of the housing is provided with an inner flange for supporting the spray buffer net, and the top of the housing is provided with a pipe joint for fixing the liquid spray pipe.

[0008] Furthermore, the water delivery hose is also connected to a water filter cartridge.

[0009] Furthermore, a liquid level meter is provided on the side of the medicine box.

[0010] Furthermore, the inclination angle of the scraper strip is 10-20°, and the scraper strip is located in the middle of the housing.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model arranges a liquid spraying pipe in a cover shell so that the spraying process is carried out in the cover shell to prevent the reagent from splashing. A buffer net is arranged in the cover shell. The spraying buffer net is located below the liquid spraying pipe so as to reduce the impact force of the spraying of the nozzle and prevent the sintered ore from being flushed and splashed. A scraper bar is also obliquely arranged on the inner wall of the cover shell. During the conveying process of the conveyor belt, the sintered ore falls onto the conveyor belt again after passing through the scraper bar. Through this process, the sintered ore is turned over, so as to facilitate the uniformity of the calcium chloride spraying. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] refer to Figure 1-2As shown, the utility model provides a device for spraying calcium chloride on sintered ore, including a cover shell 1 arranged on a conveyor belt 15, so that the spraying process is carried out in the cover shell 1 to prevent splashing when the agent is sprayed, a medicine box 11 is arranged on the cover shell 1, and a liquid level meter 13 is arranged on the side of the medicine box 11 to facilitate the detection of the liquid level. At least two spray pipes 5 are arranged on the top of the cover shell 1, preferably, the number of the spray pipes 5 is 3, and a plurality of nozzles 6 are arranged on the spray pipe 5 at intervals and the nozzles 6 are facing the conveyor belt 15. In order to transport the agent to the spray pipe 5, the spray pipes 5 are connected by a liquid delivery pipe 8, and the end of the liquid delivery pipe 8 passes through the cover shell 1 and is connected to a water hose 9, and the other end of the water hose 9 is connected to a water pump 12 in the medicine box 11. Further, In order to filter the calcium chloride agent to prevent the nozzle 6 from being blocked, a water filter cartridge 10 is connected to the water supply hose 9, and a spray buffer net 4 is also arranged in the cover shell 1. The spray buffer net 4 is a fine mesh structure, and the spray buffer net 4 is located below the nozzle 6, so as to reduce the pressure of the nozzle 6 spraying and prevent the sintered ore from being flushed and splashed.
