Detailed Description

The utility model will be further explained with reference to the drawings.

As shown in fig. 1 to 3, a sealed dust hood for a mixer, including first dust hood 1 and first dust suction pipe 2 communicating with first dust hood 1, further including the trapping cover, at least two guide plates 11, second dust hood 3 and second dust suction pipe 4, the trapping cover is a semi-closed structure with an open bottom, the trapping cover front side is provided with a ladle inlet 10, the trapping cover top and the rear side are respectively provided with a vent, first dust hood 1 is arranged at the trapping cover top and communicated with the vent at the trapping cover top, second dust hood 3 is arranged at the trapping cover rear side and communicated with the vent at the trapping cover rear side, second dust suction pipe 4 is communicated with second dust hood 3, guide plate 11 is obliquely arranged inside the trapping cover. The collecting cover is used for collecting smoke dust and preventing the smoke dust from diffusing to the outside; the guide plate 11 is used for guiding the smoke into the first dust hood 1, so that the smoke absorption effect of the first dust hood 1 is enhanced; the second dust suction hood 3 and the second dust suction pipe 4 have the function of sucking away the residual smoke dust of the trapping hood.

In order to conveniently detach and clean, the collecting cover comprises a front baffle 5, a side baffle 6, a top baffle 7 and a rear baffle 8, and the front baffle 5, the side baffle 6, the top baffle 7 and the rear baffle 8 are detachably connected through bolts or lock catches.

Guide plate 11 one end and the inside articulated of entrapment cover have connecting rod 12 between the guide plate 11, are connected with haulage rope 14 on the connecting rod 12, and haulage rope 14 wears to draw to the entrapment cover outside and be connected with the outside couple 13 of entrapment cover. Because along with the removal of taphole position, the flue gas direction is along with changing, leads to guide plate 11 inclination often and can not reach the best water conservancy diversion effect, consequently adjusts the inclination of guide plate 11 according to the flue gas direction and can realize the best water conservancy diversion effect of guide plate 11. The inclination angle adjustment process of the guide plate 11: pulling the pulling rope 14 to make the plurality of guide plates 11 synchronously rotate to the proper inclination angle, and fixing the pulling rope 14 on the hook 13.

In order to avoid the damage of the high-temperature environment to the collecting cover, the inner wall surface of the collecting cover is covered with high-temperature resistant ceramic cloth.

In order to facilitate the observation of the molten iron process, the collecting cover is provided with a transparent observation window 9.

The air vents at the top and the rear side of the trapping cover are respectively provided with a first filter screen 15 and a second filter screen 16, and the first filter screen 15 and the second filter screen 16 are used for filtering large-particle smoke dust and preventing the first dust suction pipe 2 and the second dust suction pipe 4 from being blocked.

The working principle of the utility model is as follows: when molten iron is discharged, about two thirds of iron ladles enter the trapping cover through the iron ladle inlet 10, most of smoke dust generated by the molten iron enters the first dust absorption cover 1 through the guide plate 11 and is absorbed away through the first dust absorption pipe 2; residual smoke dust in the collecting cover is sucked away through the second dust suction cover 3 and the second dust suction pipe 4, so that the rear side of the collecting cover is airtight, more than 90% of generated smoke dust can be sucked away by the device, the workshop environment is greatly improved, and the use of a covering agent is obviously reduced.

The above embodiments are only for illustrating the utility model and are not to be construed as limiting the utility model, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, therefore, all equivalent technical solutions also belong to the scope of the utility model, and the scope of the utility model is defined by the claims.
