Embodiment Construction
[0016] A collection and discharge device for casting dust generated during the production of large steel castings, such as figure 1 As shown: it includes ash discharge points 8 connected in series. All ash discharge points 8 are connected to one side of the material gas separator 5 through the main ash delivery pipe, and the other side of the material gas separator 5 is connected to the Roots through the intake pipe. The pump 7 is connected, and the lower part of the material-gas separator 5 is connected with an ash storage hopper 6 .
[0017] Such as figure 2 As shown: each ash discharge point 8 is assembled by the ash discharge winch 1 , the unloader 2 installed below the ash discharge winch 1 , the transition bucket 3 and the Venturi unloader 4 sequentially.
[0018] A pneumatic flapper valve and a material level gauge are installed in the transition bucket 3 .

The invention relates to a dust collecting device, in particular to a collecting and exhausting device for cast dust produced in a large-scale steel casting production process. The collecting and exhausting device for the cast dust produced in the large-scale steel casting production process is characterized by comprising ash-exhausting points connected in series, all the ash-exhausting points are connected with one side of a material-gas separator through an ash conveying main pipeline, the other side of the material-gas separator is connected with a roots pump through an air inlet pipeline, and the lower portion of the material-gas separator is connected with an ash storage bucket. The collecting and exhausting device for the cast dust produced in the large-scale steel casting production process can solve the secondary dust-raising problem produced during the exhausting process of the dust, reduce the labor intensity of staff, improve working efficiency and reduce maintenance cost.
Description
technical field [0001] The invention relates to a dust collection device, in particular to a collection and discharge device for casting dust generated in the production process of large steel castings. Background technique [0002] In the production process of steel castings, in order to achieve the purpose of multiple use of molding sand, the casting sand after pouring should be dust-removed through steps such as shakeout, regeneration, and separation; A large amount of metal dust will be generated. Throughout the foundry industry at home and abroad, the collection method of these dusts is mostly collected by a single high-power bag-type dust collector, and then the motor drives the winch to push the collected ash to the discharge port. Place the ash storage hopper under the feed port, and when the ash storage hopper is full, replace it with an empty ash hopper to continue storing ash, and replace the ash hopper in this way, and finally pour the ash in the ash hopper into ...
