Detailed Description

The present invention will be described in further detail with reference to the following examples:

a movable dust collecting device is shown in figure 1 and comprises a flue 2 arranged above a smelting furnace 10 and a dust remover 4 connected with the flue 2, wherein cast iron raw materials in the smelting furnace 10 can generate a large amount of white smoke and smoke dust particles which pollute the environment in the melting process, the white smoke and the smoke dust particles are effectively recovered through the flue 2 and are sent into the dust remover 4 for purification treatment, and the white smoke and the smoke dust particles are discharged to the atmosphere after being qualified in an assay, so that the environment is protected.

The flue 2 comprises an air inlet flue 2-3, a conveying flue 2-2 and an air outlet flue 2-1 which are connected in sequence, and the tail end of the air outlet flue 2-1 is connected with a dust remover 4. The dust hood 9 which slides up and down along the outer wall of the air inlet flue 2-3 is arranged on the air inlet flue 2-3, and the dust hood 9 is covered on the smelting furnace 10, so that white smoke and smoke dust particles generated in the cast iron melting process can be prevented from diffusing into the air, and the health of a person is prevented.

In order to ensure that the dust hood 9 completely covers the smelting furnace 10 and to avoid that white smoke and soot particles diffuse out from the gap between the dust hood 9 and the smelting furnace 10, the dust hood 9 needs to be in complete contact with the smelting furnace 10, for which purpose lifting means for the dust hood 9 are designed, which lifting means are arranged on the conveying flues 2-2 and are connected to the dust hood 9 by means of wire ropes 5.

As shown in fig. 1, the lifting device comprises an electric hoist 1 and a fixed pulley arranged above a dust collection cover 9, wherein the electric hoist 1 is connected with the dust collection cover 9 through a steel wire rope 5 penetrating through the fixed pulley. The fixed pulley comprises a first fixed pulley 6 and a second fixed pulley 7, one side of the first fixed pulley 6 and one side of the second fixed pulley 7 are connected with a dust collection cover 9 through a steel wire rope 5, and the other side of the first fixed pulley 6 and the other side of the second fixed pulley 7 are connected with the electric hoist 1 through the steel wire rope 5. When cast iron raw materials need to be added into the smelting furnace 10, the electric hoist 1 is manually controlled to rotate forwards, and the dust hood 1 is lifted upwards, so that a charging space is formed between the dust hood 9 and the smelting furnace 10; after the charging is finished, the electric hoist 1 is manually controlled to rotate reversely, and the dust collection cover 9 slides downwards along the outer wall of the air inlet flue 2-3 until the dust collection cover is tightly contacted with the smelting furnace 10.

The first fixed pulley 6 and the second fixed pulley 7 are both fixedly arranged on a support plate 8 above the dust hood 9, and the support plate 8 is fixedly arranged on the conveying flue 2-2 to ensure the ascending and descending of the dust hood 9.

When the volume of the cast iron raw material added into the smelting furnace 10 is too large, the dust hood 9 is lifted to the maximum limit, and the space between the dust hood 9 and the smelting furnace 10 does not contain large blocks of cast iron raw material, in order to avoid the waste of manpower and financial resources caused by cutting large materials, as shown in fig. 1, a rotating device 3 is arranged on an air outlet channel 2-1, and the rotating device 3 is a rotating bearing. At the moment, as long as the dust hood 9 is manually pushed in the horizontal direction, the dust hood 9 and the flue 2 rotate around the rotating device 3 together with the lifting device on the conveying flue 2-2, the dust hood 9 is smoothly removed from the smelting furnace 10, after the charging is finished, the dust hood 9 is pushed to the upper part of the smelting furnace 10, and the electric hoist 1 of the lifting device is controlled to ensure that the dust hood 9 is in tight contact with the smelting furnace 10 when necessary. The implementation of the device not only purifies the environment, but also facilitates the production, and has the need of popularization.

Finally, it should be noted that: the above examples are merely illustrative for the clarity of the present invention and are in no way intended to limit the scope of the invention. It will be apparent to those skilled in the art that many more modifications and variations than mentioned above are possible in light of the above teaching, and it is not intended to be exhaustive or to limit the invention to the precise form disclosed.
