Filler sucking and discharging overhead crane for graphite refining

Abstract

The invention discloses a filler sucking and discharging overhead crane for graphite refining, and relates to the technical field of graphite electrode production. The filler sucking and discharging overhead crane for graphite refining comprises a main beam, a trolley frame, a discharging bin, a discharging pipe and a buffering bin, the discharging bin is connected with the discharging pipe, a spreading head is mounted at the lower end of the discharging pipe, and an exhaust fan and a sucking pipe are arranged at the upper end and the lower end of the buffering bin respectively; a rotary support is arranged between the discharging pipe and the spreading head; two two-position four-way valves are installed at the two ends of the sucking pipe respectively, each four-way valve body is provided with a main passageway, an auxiliary passageway and two side passageways, two semicircular pipes are arranged outside the sucking pipe, the lower ports of the two semicircular pipes correspondingly communicate with the two side passageways of the four-way valve body at the bottom end of the sucking pipe respectively, and the upper ports of the two semicircular pipes correspondingly communicate with two side passageways of the four-way valve body at the top end of the sucking pipe respectively; and a cold water outlet pipe and a cold water inlet pipe are respectively arranged at the top end and the bottom end of the sucking pipe. The sucking and discharging overhead crane not only can greatly widen the temperature application range of material sucking, but also can adapt to material spreading sites with various widths, and the discharging efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of graphite electrode production, in particular to a filling material suction and discharge crane for graphite refining. Background technique [0002] At present, the suction and laying operations of filler materials in graphite refining are generally carried out by suction and unloading cranes. The existing suction and unloading cranes are generally equipped with corresponding suction and unloading systems, cooling systems, dust removal systems, electric Control system, etc., can directly absorb the red hot material, can improve the temperature, speed and dust removal effect of the material, and then improve the efficiency of furnace loading. When unloading, the filling material in the unloading bin will pass through the discharge pipe Fall naturally, and stack them in a specific place; however, when the temperature of the filling material is too high, it will increase the cooling burden of the suction cran...

Problems solved by technology

[0002] At present, the suction and laying operations of filler materials in graphite refining are generally carried out by suction and unloading cranes. The existing suction and unloading cranes are generally equipped with corresponding suction and unloading systems, cooling systems, dust removal systems, electric Control system, etc., can directly absorb the red hot material, can improve the temperature, speed and dust removal effect of the material, and then improve the efficiency of furnace loading. When unloading, the filling material in the unloading bin will pass through the discharge pipe Fall naturally, and stack them in a specific place; however, when the temperature of the filling material is too high, it will increase the cooling burden of the suction crane itself, reduce the cooling efficiency, and prolong the cooling time. Improvements are made on the basis of the system to meet more material suction needs; in addition, in the past, in the process of unloading and spreading, because the length, width and position of the outlet of the unloading pipe are fixed, and the width of the spreading site is variable, often It is necessary to control the suction crane to move back and forth multiple times, which reduces the efficiency of unloading
