Description

Technical Field

[0001] The utility model belongs to the technical field of electrode paste production, and particularly relates to an exhaust gas recovery pipeline for electrode paste production. Background Art

[0002] Electrode paste is a conductive material supplied to electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. Electrode paste is also called a self-baking electrode, and it is baked by the heat in the submerged arc furnace. Therefore, the key to the use of electrode paste is that the consumption rate of the electrode matches the baking rate. A large amount of exhaust gas is generated during the electrode paste production process, which is discharged into the asphalt storage tank through a closed conveying pipeline for heat preservation storage, generating asphalt storage exhaust gas. The fine grinding process generates ball mill dust exhaust gas, and the asphalt melting pool heats the asphalt to generate asphalt melting exhaust gas. Therefore, it is necessary to treat the generated exhaust gas.

[0003] The exhaust gas is discharged through the exhaust gas recovery pipeline and recovered after treatment. During the treatment, it is often filtered through a filter component. When the exhaust gas passes through the recovery pipeline and impurities adhere to the inner wall of the pipeline, it is easy to increase the burden on the use of the filter component and reduce the use effect of the recovery pipeline after long-term use. Content of the Utility Model

[0004] The utility model provides an exhaust gas recovery pipeline for electrode paste production, which has the characteristics of being beneficial to improving the service life of the recovery pipe and the use effect of the recovery pipeline.

[0005] The utility model provides the following technical solution: an exhaust gas recovery pipeline for electrode paste production, including a recovery pipe, wherein a filter element for filtering exhaust gas is arranged inside the recovery pipe, and a driving air control component is arranged at the air inlet end of the recovery pipe. The driving air control component includes an externally attached rotating ring, an internally connected rotating disk and a driving shaft. An inner surface attaching plate is fixedly connected to the inner end face of the externally attached rotating ring. One end face of the inner surface attaching plate coincides with the inner surface of the recovery pipe. The inner surface attaching plate is provided with a transition cavity, a squeezing treatment cavity and a storage and cleaning cavity. An inclined guiding surface for guiding impurities is arranged in the squeezing treatment cavity, and the side of the inclined guiding surface close to the inner wall of the recovery pipe is a contraction end.

[0006] Wherein, the externally attached rotating ring is rotationally connected with the recovery pipe, and the internally connected rotating disk is fixedly connected with the externally attached rotating ring through a plurality of connecting rods.

[0007] Wherein, a ventilation cavity is arranged between every two connecting rods, and a driving shaft is fixedly installed on the connecting rod.

[0008] Wherein, the transition cavity is communicated with the squeezing treatment cavity, and the storage and cleaning cavity is communicated with the transition cavity.

[0009] Among them, a suction pipe is fixedly installed in the storage and cleaning cavity. When the suction pipe is opened, an attraction force is generated at the position where the extrusion treatment cavity is located.

[0010] Among them, the inner surface attaching plate is located inside the recovery pipe, and one side of the extrusion treatment cavity is in a closed state.

[0011] The beneficial effects of the present utility model are as follows:

[0012] By setting the driving air control component including an outer attached rotating ring, an inner connected rotating disk and a driving shaft, an inner surface attaching plate is fixedly connected to the inner end face of the outer attached rotating ring. As the recovery pipeline is used, the driving shaft can be periodically opened to drive the outer attached rotating ring to rotate, so that the inner surface attaching plate can move inside the recovery pipe. At this time, the inner surface attaching plate can clean the impurities on the inner wall of the recovery pipe, and the inclined guiding surface can guide the position of the impurities. The impurities can be extruded into the storage and cleaning cavity through the extrusion treatment cavity, which is beneficial to improving the service life of the recovery pipe and the use effect of the recovery pipeline.
