Simple automatic sand feeding device
Technical Field
The invention relates to the field of electric furnaces, in particular to a simple automatic sand feeding device.
Background
The electric furnace is a heating furnace which converts electric energy in the furnace into heat to heat a workpiece.
Electric furnaces are broadly classified into resistance furnaces, induction furnaces, arc furnaces, plasma furnaces, electron beam furnaces, and the like, and have the advantages of easy control of the furnace atmosphere, rapid material heating, high heating temperature, easy control of the temperature, and are often used in steel processing.
When the tapping hole of the electric furnace is normally smelted, the tapping hole is sealed by virtue of filled drainage sand, the drainage sand is stored in a sand box on a furnace cover at ordinary times, when the sand box is not filled with the drainage sand, the drainage sand needs to be supplemented in time, and the traditional drainage sand adding is that personnel need to climb up the furnace cover by taking scissors to cut sand bags, so that the drainage sand flows into the sand box, the electric furnace needs to stop oxygen blowing and electrifying for personnel safety, normal production can be restored after the personnel get down, the production rhythm is restricted to a certain extent, and the production efficiency is greatly reduced; therefore, a simple automatic sand feeding device is provided for solving the problems.
Disclosure of Invention
In order to make up the deficiency of the prior art, solve the tapping hole of the electric furnace and in normal smelting, rely on the drainage sand that fills to seal the tapping hole in the tapping hole, and the drainage sand is deposited in the sand box on the bell at ordinary times, when there is no drainage sand in the sand box, need in time to supplement the drainage sand, and traditional the drainage sand that adds is that needs personnel to take the scissors to climb up the bell to cut broken sand bag, let the drainage sand flow into the sand box, for personnel's safety, the electric furnace need stop blowing oxygen and circular telegram, can resume normal production after personnel's coming down, restrict the rhythm of production to a certain extent, greatly reduced production efficiency's problem, the invention proposes a simple and easy automatic sand adding device.
The technical scheme adopted for solving the technical problems is as follows: the invention relates to a simple automatic sand feeding device, which comprises a sand box and a fixed frame; the sand box is characterized in that a fixed frame is fixedly arranged in the sand box, a filter screen is fixedly arranged on the inner wall of the fixed frame, a base is fixedly arranged at the top of the fixed frame, a bottom column is fixedly arranged at the top of the base, and a tip piece is fixedly arranged at one end, far away from the base, of the bottom column; during operation, hang the sand bag that is equipped with drainage sand to the top of sand box through driving for the sand bag is in the top of tip spare, and rethread driving is with the sand bag to the direction below of sand box slowly this moment, makes sand bag and tip spare contact, lets tip spare puncture the sand bag, thereby makes the drainage sand in the sand bag fall into in the fixed frame of sand box, and the filter screen on the fixed frame lets drainage sand slowly flow into in the sand box, thereby need not let the electric stove shut down, lets the manual work go to cut the sand bag on the electric stove again, makes the electric stove can keep working, does not influence the work efficiency of electric stove.
Preferably, a fixed groove is formed in one side of the base, a guide plate is arranged on one side of the base, two sides of the guide plate are inclined, and a fixed block is fixedly arranged at the bottom of the guide plate; during operation, insert the fixed block on the guide plate into the fixed slot of base in the chucking fixedly for the guide plate is fixed on the base, and the drainage sand that the sand bag flowed can fall on the guide plate this moment, because the slope form when the both sides of guide plate, so the drainage sand can continue to flow into in the sand box along the guide plate, avoids the drainage sand to pile up on the base.
Preferably, an insert block is inserted on one side of the base in a sliding manner, one side of the insert block is arc-shaped, sealing rings are fixedly arranged on two sides of the insert block, and a diversion trench is formed in the top of the insert block; during operation, insert two guide plates directly with the kicking block, and arc one side and the sill pillar on the guide plate avoid laminating mutually, and the sealing washer of kicking block both sides is laminated and then is sealed mutually with two guide plates for two guide plates are direct can not have the space any more, avoid having drainage sand to fall into in the gap.
