A kind of multifunctional crane unloading online automatic screening and crushing system and its operation method

Abstract

The invention discloses a multi-functional crane unloading online automatic screening and crushing system and an operation method thereof. On the multi-functional crane operating platform, the conical bottom opening of the packing silo on one side of the original unloading pipe leads to a newly installed unloading pipeline. , the newly installed discharge pipeline is connected with the newly installed electric discharge valve, the trommel screen is connected with the newly installed electric discharge valve, the double-toothed roller crusher and the screw conveyor are respectively connected with the trommel screen, and the screw conveyor is connected with the original discharge pipe. The dust collection pipe is connected between the trommel screen and the double-toothed roller crusher, and the newly installed dust collection pipe is connected with the original dust collection pipe on the multifunctional crane operating platform. The invention cleverly utilizes the original discharging process on the multi-functional crane to automatically complete the screening and crushing operations of the filling material online while discharging, and then feed it into the original new charging and discharging pipeline through the screw conveyor without increasing the process time. Reduce manual operation, improve automation control level, greatly improve labor efficiency and production efficiency.

Description

technical field [0001] The invention relates to the technical field of raw anode carbon block production equipment for aluminum, in particular to a multi-functional crane discharging on-line automatic screening and crushing system and an operation method thereof. Background technique [0002] The raw anode carbon block for aluminum is made of calcined petroleum coke and coal pitch. In order to improve the electrolysis operating environment and improve its physical and chemical properties, it needs to be calcined at high temperature in advance before being put into the tank. In order to prevent the deformation and cracking of the raw anode carbon block due to stress release during the roasting process, it is necessary to place metallurgical coke or petroleum coke with a filler of 0-6mm around the raw anode carbon block when charging the furnace. The charcoal block is protected. When the calcined charcoal block comes out of the furnace, the filler needs to be sucked out, and t...

Problems solved by technology

[0004] Aiming at the large particles such as coke lumps and castable blocks in the filling material during the roasting of the anode carbon block seriously affect the quality of the anode carbon block, the current multi-functional crane does not have the function of screening and crushing of the filling material and the corresponding equipment, and a new special filling Material screening, crushing, and dust removal systems require large investment, low production efficiency, and large pollution. For this reason, the present invention provides a multi-functional crane discharging online automatic screening and crushing system and its operation method
