Blast furnace bin structure capable of preventing blanking

Abstract

The utility model discloses an anti-blanking blast furnace bin structure which comprises a bin, a rectangular clamping plate groove is arranged at the lower end of a flow nozzle at the bottom of the bin, a rubber plate is inserted in the rectangular clamping plate groove in a matched mode, the length of the rubber plate is matched with the length of an opening at the bottom end of the bin, and the lower end of the rubber plate extends into a material receiving opening of a skip car. According to the utility model, the phenomenon of material leakage of the flow nozzle of the stock bin in the discharging process can be solved, material accumulation in a material pit is avoided, and the waste of manpower, material resources and time during material cleaning in the material pit is reduced.

Description

Technical Field

[0001] The utility model relates to a blast furnace material bin structure for preventing material from falling. Background Art

[0002] During the process of preparing materials for the blast furnace ironmaking through the material car, during the discharge process of the nozzles of the East Mine, East Coke, West Mine, and West Coke silos, since the material car and the silo nozzle are both steel structures, if the silo nozzle is close to the material car, it is easy to cause equipment collision and damage to the equipment and rollover accidents, resulting in a long-term stoppage of the blast furnace. Therefore, the nozzle of the silo and the silo are directly kept at a certain distance. Therefore, due to the impact force during material discharge, the granular material basically falls into the material car, but the foam near the bottom of the silo nozzle is difficult to enter the material car and falls to the bottom of the material car, forming an accumulation. Over time, the accumulated materials will lift up the material car, causing the material car to derail and cause a production accident. Every time the accumulated materials are cleaned up, they can only be safely cleaned up during the scheduled maintenance every other month, which wastes a certain amount of manpower and time. The main problems are as follows: when the center pit bucket of the ore trough is discharged, the foam falls into the pit, causing the material car to lift up, which is easy to cause a material car accident and increase the labor intensity of employees. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a blast furnace silo structure that prevents material from falling, solves the problem of material leakage from the silo nozzle during the discharge process, prevents material accumulation in the silo, and reduces the waste of manpower, material resources and time when clearing the silo.

[0004] The technical solution adopted by the utility model is a blast furnace silo structure for preventing material from falling, comprising a silo, a rectangular clamping plate groove is arranged at the lower end of the flow nozzle at the bottom of the silo, a rubber plate is inserted in the rectangular clamping plate groove, the length of the rubber plate matches the length of the opening at the bottom of the silo, and the lower end of the rubber plate extends to the receiving port of the material car.

[0005] The structure of the utility model can effectively extend the length of the nozzle at the bottom of the silo, so that the foam does not overflow, and can also reduce the collision force between the nozzle and the material vehicle, making it less likely for equipment to collide and cause equipment damage and material vehicle rollover accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 It is a schematic diagram of the main structure of the utility model. DETAILED DESCRIPTION

[0007] A blast furnace silo structure to prevent material falling, such as Figure 1 As shown, it includes a silo 5, a rectangular clamping plate groove 7 is provided at the lower end of the flow nozzle 6 at the bottom of the silo 5, a rubber plate 8 is inserted in the rectangular clamping plate groove 7, the length of the rubber plate 8 matches the length of the opening at the bottom end of the silo, and the lower end of the rubber plate extends to the material receiving port 9 of the material cart 4.

[0008] During operation, the material cart 4 having the traction arm 2 and the bracket 1 is pulled by an external force and supported by the material wheels 3 to run on the track. Since the rubber sheet 8 extends the discharge length and range of the flow nozzle 6, the phenomenon of material leakage in the silo 5 is completely prevented.

[0009] In addition, the utility model can also adopt other structural forms of rubber plate supporting and fixing structures at the bottom spout of the silo, such as setting a groove or convex ridge at the rear end of the rubber plate, and setting a slideway matching the groove or convex ridge at the bottom spout of the silo. The slideway is connected to the rubber plate, which is not only firmly connected but also saves time and effort.

Claims

1. A blast furnace silo structure for preventing material from falling, comprising a silo, characterized in that: A rectangular clamping plate groove is arranged at the lower end of the flow nozzle at the bottom of the silo, and a rubber plate is inserted into the rectangular clamping plate groove.
