Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting, in particular to a material control device for adding inoculant for metal smelting. Background Art

[0002] Casting is a process of melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling and solidification, cleaning and treatment, a casting with a predetermined shape, size and performance is obtained. Because the casting blank is almost formed, it can be machined or the processing cost and processing time are reduced, which greatly improves efficiency and is one of the foundations of the entire machinery manufacturing. As the chemical composition and mechanical properties of the product material are different, especially in the casting process of high-strength and high-grade gray cast iron, or relatively thick-walled ductile iron, it is usually necessary to add an inoculant for inoculation. Most of the existing inoculants are weighed by the operator according to the weight of the casting molten iron and then poured into the casting molten iron for inoculation. When the factory produces the same batch of products, the weight of the casting molten iron used is the same, but each time the inoculant is added, the operator needs to weigh and add it again. This method has high labor intensity and low work efficiency. Summary of the invention

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a metal smelting inoculant adding and controlling device with reasonable structure and good use effect.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a metal smelting inoculant adding and controlling device, which includes a storage barrel, a feeding port is provided at the top of one side of the storage barrel, a discharge pipe is installed at the upper part of the other side of the storage barrel, a control plate is installed in the inner cavity of the storage barrel, an adjusting screw is movably installed at the center of the bottom of the control plate, a threaded hole penetrating inside and outside is provided at the center of the bottom of the storage barrel, the bottom of the adjusting screw passes downward through the threaded hole and is connected to the adjusting knob, a guide rod is vertically installed at the bottom of the control plate on one side of the adjusting screw, a scale is provided on the guide rod, a guide hole penetrating inside and outside is provided at the center of the bottom of the storage barrel below the guide rod, and the bottom of the guide rod passes downward through the guide hole to form a guide end.

[0005] A bearing seat is installed at the center of the bottom of the storage barrel, a bearing is installed at the top of the adjusting screw, and the bearing is installed on the bearing seat.

[0006] One end of the discharge pipe is connected to the storage barrel, and the other end of the discharge pipe is inclined downward to form a discharge end. An extension pipe is movably sleeved in the discharge end. A locking bolt is installed on the discharge pipe of the discharge end, and the extension pipe is locked and fixed by the locking bolt.

[0007] The discharge pipe and the storage barrel are reinforced and fixed by a reinforcing rod.

[0008] Concave lifting grooves are arranged on both sides of the inner cavity of the material storage barrel, and limiting plates are extended at both ends of the material control plate, and the limiting plates are movably embedded in the lifting grooves.

[0009] After the utility model adopts the above scheme, the weight of the inoculant is first calculated according to the weight of the molten iron poured for casting, and then the volume of the storage barrel is adjusted so that the volume of the storage barrel just corresponds to the weight of the inoculant. The volume of the storage barrel can be adjusted by adjusting the height of the material control plate. During adjustment: by rotating the adjusting knob, the adjusting knob drives the adjusting screw to rotate, and the adjusting screw runs upward (or downward) under the action of the thread when rotating, and the adjusting screw drives the material control plate to run upward (or downward) synchronously when running upward (or downward), and the material control plate drives the guide rod to move synchronously when running, and the volume of the storage barrel can be measured by observing the scale on the guide rod. After the volume of the storage barrel is adjusted, the inoculant is added into the storage barrel through the feed port. When the storage barrel is full, the inoculant in the storage barrel is the required weight. After adopting the above scheme, the utility model has a reasonable structure and good use effect.
