Description
Technical Field
[0001] The utility model relates to the technical field of circulating flow equalizing covers, and particularly relates to a sintering flue gas circulating flow equalizing cover. Background Art
[0002] A circulating flow equalizing cover is a device used to achieve uniform distribution and recycling of fluids in specific fields. It usually has a specific shape design, such as an arch shape, a cone shape, or a cuboid shape, etc., to adapt to different installation environments and fluid flow requirements. Its internal space is generally large enough to accommodate a certain amount of fluid passing through.
[0003] When the existing circulating flow equalizing cover equalizes the sintering flue gas in a circulating manner, there is no structure for filtering the sintering flue gas. However, the sintering flue gas usually contains a large amount of impurities such as dust and particulate matter. If these impurities enter the circulating flow equalizing cover and subsequent pipelines and equipment without being filtered, they are likely to accumulate at positions such as the inner wall of the pipeline, the inlets and outlets of the equipment, and the impeller, resulting in pipeline blockage and poor operation of the equipment. In the long run, it will seriously affect the performance and service life of the equipment and increase the cost of equipment maintenance and replacement. Summary of the Utility Model

[0027] A preferred embodiment of a sintering flue gas circulation flow equalizing hood provided by the present utility model is as Figures 1-4 shown: A sintering flue gas circulation flow equalizing hood includes a flow equalizing hood 1. Support legs 2 are uniformly and fixedly installed at the bottom of the flow equalizing hood 1. A smoke inlet pipe 5 is communicatively arranged on one side of the flow equalizing hood 1.

Since the clamping rods 316 on the inner side of the baffle 315 are clamped and connected to the clamping grooves on the front surface of the flow equalizing hood 1, pulling the baffle 315 can drive the installation frame 313 to slide out of the flow equalizing hood 1 through the connection port.

The first motor 327 drives the rotating shafts 325 on both sides of the connection box 324 to rotate, thereby driving the connection box 324 to rotate within the flow equalizing cover 1. The nozzles 326 at the bottom of the connection box 324 evenly spray water on the filter cloth 314, which can increase the humidity of the flue gas, reduce the temperature of the flue gas, reduce the adverse effects on subsequent equipment, and simultaneously filter the flue gas again.
[0032] Embodiment 3
[0033] On the basis of Embodiments 1 and 2, a preferred embodiment of the sintering flue gas circulation flow equalizing cover provided by the present utility model is as Figures 1-4 shown: The adjusting component 4 includes: a first smoke guiding plate 411, fixedly installed inside the flow equalizing cover 1; a long shaft 412, symmetrically and movably connected inside the flow equalizing cover 1; a second motor 415, fixedly installed on the back of the flow equalizing cover 1; one end of the long shaft 412 movably penetrates through the back of the inner wall of the flow equalizing cover 1 and extends to the back of the outer wall of the flow equalizing cover 1. A second smoke guiding plate 413 is fixedly sleeved on the outer wall of the long shaft 412. The other end of the long shaft 412 is rotatably connected to the flow equalizing cover 1 through a bearing. The output end of the second motor 415 is connected to one end of one of the long shafts 412. A gear 414 is fixedly sleeved on the outer wall of one end of the long shaft 412, and the gears 414 are meshed with each other.
[0034] Furthermore, in the embodiment, the first smoke guiding plate 411 is fixed inside the flow equalizing cover 1 to play a role in initially guiding the flow of the flue gas. The second motor 415 drives one of the long shafts 412 to rotate. The gears 414 on the outer walls of the long shafts 412 are meshed with each other, so that the two long shafts 412 rotate synchronously. The second smoke guiding plates 413 fixedly sleeved on the long shafts 412 rotate accordingly. By adjusting the angle of the second smoke guiding plates 413, the flow direction and speed of the flue gas inside the flow equalizing cover 1 can be changed, the regulation of the flue gas flow rate can be realized, and the flue gas can be more evenly distributed inside the flow equalizing cover 1, so as to better perform subsequent treatment and recycling.
[0035] During use, when the sintering flue gas enters the flow equalizing hood 1 from the inlet flue pipe 5, it first passes through the filter cloth 314 for filtration to remove some particulate matters and impurities in the flue gas. When it is necessary to replace and clean the filter cloth 314, the staff pulls the baffle 315 through the handle 317. Since the engaging rod 316 inside the baffle 315 is engaged with the engaging groove on the front of the flow equalizing hood 1, pulling the baffle 315 can drive the mounting frame 313 to slide out of the flow equalizing hood 1 through the connection port. After cleaning the filter cloth 314, the mounting frame 313 is pushed back into the flow equalizing hood 1 to make the engaging rod 316 snap into the engaging groove, completing the cleaning operation of the filter cloth 314. Connect the water suction pipe 322 to an external water source. The water pump 321 extracts water from the external water source through the water suction pipe 322, and then conveys the water into the connection box 324 through the hose 323. The first motor 327 drives the rotating shafts 325 on both sides of the connection box 324 to rotate, thereby driving the connection box 324 to rotate inside the flow equalizing hood 1. The spray heads 326 at the bottom of the connection box 324 evenly spray water on the filter cloth 314, which can increase the humidity of the flue gas, reduce the temperature of the flue gas, reduce the adverse effects on subsequent equipment, and at the same time filter the flue gas again. The smoke guiding plate 411 is fixed inside the flow equalizing hood 1 to play a role in initially guiding the flow of the flue gas. The second motor 415 drives one of the long shafts 412 to rotate, and the gears 414 on the outer wall of the long shaft 412 mesh with each other, causing the two long shafts 412 to rotate synchronously. The smoke guiding plates 413 fixedly sleeved on the long shafts 412 rotate accordingly. By adjusting the angle of the smoke guiding plate 413, the flow direction and speed of the flue gas inside the flow equalizing hood 1 can be changed, realizing the regulation of the flue gas flow rate, and making the flue gas more evenly distributed inside the flow equalizing hood 1 for better subsequent treatment and recycling.
