Abstract

The invention relates to the technical field of dust collecting equipment, and discloses a casting electric furnace dust collecting device, which comprises a bottom plate. A supporting plate is fixedly connected to the upper surface of the bottom plate, a fixing frame is fixedly connected to the side wall of the supporting plate, a dust collecting cover is fixedly connected to the inner wall of the fixing frame, a preheating mechanism is fixedly connected to the upper surface of the bottom plate, the top end of the dust collecting cover fixedly communicates with a conveying pipe, the bottom end of the conveying pipe fixedly communicates with the outer wall of the bottom end of the preheating mechanism, the upper surface of the preheating mechanism fixedly communicates with a guide pipe, the bottom end of the guide pipe fixedly communicates with a collecting box, and the outer wall of the collecting box is fixedly connected with a connecting block. According to the casting electric furnace dust collecting device, the dust collecting device can have the waste heat recovery function, heat waste is avoided, meanwhile, the heat utilization rate of the device is increased, the material heating efficiency of a casting electric furnace can be improved, the dust collecting effect of the dust collecting device can be effectively improved, fine dust is prevented from polluting the environment, and the environment-friendly performance of the casting electric furnace dust collecting device is improved.

Description

technical field [0001] The invention relates to the technical field of dust collection equipment, in particular to a dust collection device for a foundry electric furnace. Background technique [0002] At present, a large number of metal cutting processes are carried out in the production process of the machinery industry, which produces a large amount of metal waste. If these wastes are discarded, it will not only waste resources, but also seriously pollute the environment. Therefore, these metal wastes are recycled. , After processing, returning to the furnace for smelting is an effective treatment method. Since metal waste contains more impurities during the smelting process, a large amount of fine dust is prone to appear during the heating process. [0003] At present, when the casting electric furnace dust floats out, a large amount of heat will flow out, but the existing dust collection device cannot collect heat and cause heat waste, which affects the heat utilization...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a casting electric furnace dust collection device, which can make the dust collection device have the function of waste heat recovery, avoid heat waste, improve the utilization rate of heat of the device at the same time, and can improve the heating efficiency of the casting electric furnace. The efficiency of the material can also effectively improve the dust collection effect of the dust collection device, avoid fine dust from polluting the environment, improve the environmental protection performance of the dust collection device of the foundry electric furnace, and solve the problem that a large amount of heat will flow out when the dust of the foundry electric furnace is released. , but the existing dust collection device cannot collect heat and cause waste of heat, which affects the heat utilization rate of the device, and the dust collection device of the casting electric furnace is still poor and has the problem of poor dust collection effect
