Description

Technical Field

[0001] The utility model relates to the field of casting hoppers, and more particularly to an anti-burst iron ditch casting hopper. Background Art

[0002] Iron trough castable is a refractory castable used in the iron trough of the blast furnace iron-making yard. It is made of fused corundum, silicon carbide and carbon graphite as refractory raw materials, with additives and binders added. It is a burst-resistant iron trough castable made by mixing according to the formula ratio. A hopper is required to transport molten metal or other high-temperature materials from the smelting equipment to the forming mold or other equipment.

[0003] In the commonly used conical or tubular hoppers, the granular materials in the hopper will settle due to gravity, resulting in stratification or unevenness, which affects the quality and consistency of the final product. The flow of materials in the hopper will be restricted, resulting in poor discharge. Therefore, we proposed an anti-burst iron trough casting hopper to solve the above problems.

[0028] See also Figure 1 - Figure 3 A burst-resistant iron ditch pouring hopper includes a burst-resistant iron ditch pouring hopper, including a conveying hopper 1, a mounting frame 2 is fixedly installed on the top of the conveying hopper 1, a motor 3 is fixedly installed on the top of the mounting frame 2, the output end of the motor 3 is fixedly connected to a rotating shaft 4, the bottom of the rotating shaft 4 is rotatably connected to the bottom of the inner wall of the conveying hopper 1, and a spiral blade 18 is fixedly installed on the outer wall of the rotating shaft 4. The edge of the spiral blade 18 is in contact with the inner wall of the conveying hopper 1, a feed pipe 5 is installed through the top of the conveying hopper 1, an air intake pipe 6 is installed through the top of the conveying hopper 1, a plurality of discharge troughs 7 are opened through the bottom of the conveying hopper 1, and a discharge pipe 17 is fixedly installed on the bottom of the conveying hopper 1.

[0029] When the hopper is used to cast a certain type of anti-explosion iron ditch castable, the castable is first introduced into the top of the feed pipe 5, and inert gas is introduced from the air inlet pipe 6. Then the motor 3 is started to drive the rotating shaft 4 to rotate, and the rotating shaft 4 drives the spiral blade 18 to rotate. During the rotation of the spiral blade 18, the castable is stirred and fed. The castable is gradually transported downward and flows from the discharge trough 7 into the discharge pipe 17. The bottom of the discharge pipe 17 is connected to other molds or receiving equipment. By setting the spiral blade 18, the inner wall of the conveying bucket 1 is set to a downward pointed cone shape, and a gradual spiral blade 18 that fits the shape of the inner wall is provided inside. The pointed cone shape of the inner wall of the conveying bucket 1 can effectively guide the material to flow downward, reduce the stagnation of the material in the bucket, and contribute to smooth discharge. The spiral blade 18 can achieve better stirring during the flow of the material, maintain the fluidity of the material, and prevent the material from adhering to the inner wall of the conveying bucket 1 for a long time.

[0030] See Figure 1 - Figure 5 A rotating groove 8 is provided inside the conveying bucket 1, and a rotating disk 9 is rotatably provided inside the rotating groove 8. A plurality of material passing grooves 10 are provided inside the rotating disk 9. The positions of the material passing grooves 10 correspond to the positions of the material discharge trough 7. A rotating rod 11 is fixedly installed on one side of the rotating disk 9. The rotating rod 11 is movably provided inside the rotating groove 8. A rotating handle 12 is fixedly installed on one side of the rotating rod 11, and the rotating handle 12 is provided on the outside of the conveying bucket 1.

[0031] When using the hopper, first push the rotating handle 12 so that the rotating handle 12 drives the rotating rod 11 to deflect inside the rotating groove 8, and the rotating disk 9 rotates inside the rotating groove 8, so that the position of the through trough 10 and the position of the discharge trough 7 are relatively deflected, and the top of the rotating disk 9 fits with the inner wall of the rotating groove 8, and the bottom of the rotating disk 9 fits with the inner wall of the rotating groove 8. By setting the rotating groove 8 and the rotating disk 9, the relative position of the discharge trough 7 and the through trough 10 can be adjusted, and the discharge rate can be adjusted according to the needs of different production processes to adapt to different materials and process requirements. The motor 3 adjusts the rotation speed of the rotating shaft 4 and the spiral blade 18 to effectively control the fluidity of the material and avoid accumulation or waste of material due to excessively fast discharge.

[0032] See Figure 2 and Figure 3 The outer wall of the conveying bucket 1 is provided with a limiting groove 13, and a thermal resistance wire 14 is clamped inside the limiting groove 13. The outer wall of the conveying bucket 1 is fixedly sleeved with an insulation layer 15, and the inner wall of the insulation layer 15 is provided with a positioning groove 16. One side of the positioning groove 16 is in contact with one side of the thermal resistance wire 14, and both ends of the thermal resistance wire 14 pass through the insulation layer 15.

[0033] During the use of the hopper, the two ends of the thermal resistance wire 14 are connected to the power supply to form a loop, and the internal power of the thermal resistance wire 14 generates heat to heat the outer wall of the conveying hopper 1. The thermal insulation layer 15 insulates the outer wall of the conveying hopper 1. The limiting groove 13 and the positioning groove 16 cooperate to fix the position of the thermal resistance wire 14. The thermal resistance wire 14 is evenly arranged on the outer wall of the conveying hopper 1 for heating. By setting the thermal resistance wire 14 and the thermal insulation layer 15, the temperature of the material in the conveying hopper 1 is maintained, which helps to ensure the consistency and reaction activity of the material. The thermal insulation layer 15 can effectively reduce heat loss, maintain the high temperature state inside the conveying hopper 1, improve heat utilization efficiency, and thus save energy costs.

[0034] Working principle: When using this hopper to cast a certain anti-burst iron trough castable, first push the rotating handle 12, so that the rotating handle 12 drives the rotating rod 11 to deflect inside the rotating groove 8, and the rotating disk 9 rotates inside the rotating groove 8, so that the position of the material trough 10 and the position of the discharge trough 7 are relatively deflected, and the top of the rotating disk 9 fits with the inner wall of the rotating groove 8, and the bottom of the rotating disk 9 fits with the inner wall of the rotating groove 8.

[0035] Then, both ends of the thermal resistance wire 14 are connected to a power supply to form a loop. The thermal resistance wire 14 is energized to generate heat, which heats the outer wall of the conveying bucket 1. The thermal insulation layer 15 keeps the outer wall of the conveying bucket 1 warm. The limiting groove 13 and the positioning groove 16 cooperate to fix the position of the thermal resistance wire 14. The thermal resistance wire 14 is evenly arranged on the outer wall of the conveying bucket 1 for heating.

[0036] Finally, the castable is introduced into the top of the feed pipe 5, and inert gas is introduced from the air inlet pipe 6. Then the motor 3 is started to drive the rotating shaft 4 to rotate, and the rotating shaft 4 drives the spiral blade 18 to rotate. During the rotation of the spiral blade 18, the castable is stirred and fed. The castable is gradually transported downward and flows from the discharge trough 7 into the discharge pipe 17. The bottom of the discharge pipe 17 is connected to other molds or receiving equipment.
