Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for iron and steel metallurgy production systems, and particularly relates to a shaft rod baffle feeding hopper for a ferroalloy submerged arc furnace ramming machine. Background Art

[0002] During the process of smelting metals in a ferroalloy submerged arc furnace, it is necessary to add auxiliary materials into the smelting furnace. The front end of the original open feeding hopper cannot be filled with materials, and the materials are prone to falling during transportation. When unloading the materials into the furnace, the material distribution is uneven, resulting in low efficiency. Content of the Utility Model

[0003] The purpose of the utility model is to provide a shaft rod baffle feeding hopper for a ferroalloy submerged arc furnace ramming machine to solve the above problems.

[0004] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0005] A shaft rod baffle feeding hopper for a ferroalloy submerged arc furnace ramming machine includes a hopper. Both ends of the hopper are open, one end is set as the discharge port, and the other end is set as the extrusion port. A baffle is arranged on the discharge port. The included angle between the bottom edge of the baffle and the bottom surface of the hopper is an acute angle. A shaft rod is arranged on the top surface of the baffle. Connecting blocks extending outward are symmetrically arranged at the top of the discharge port. Through holes are arranged in the connecting blocks, and both ends of the shaft rod are arranged in the through holes. A push plate is clamped in the extrusion port, and the rear end wall of the push plate is connected with the hydraulic mechanism of the ramming machine.

[0006] In order to further implement the utility model, the four side walls of the push plate and the baffle are respectively attached to the inner walls of the extrusion port and the discharge port.

[0007] In order to further implement the utility model, the connecting block is arranged on the outer wall of the discharge port.

[0008] The beneficial effects of the utility model compared with the prior art are as follows:

[0009] The utility model is provided with a baffle that can be turned up at the front end of the feeding hopper. During the loading and transportation process, the materials will not easily fall. After being transported into the submerged arc furnace, the hydraulic mechanism of the ramming machine is used to push out the push plate, so that the materials are evenly distributed into the submerged arc furnace. After the materials are emptied, the push plate is retracted, and the baffle returns to its original position by its own weight to resume blocking, so as to achieve the purposes of good loading, unloading, safety and improving operation efficiency.

[0011] The meanings of the reference numerals are as follows: 1. Hopper; 2. Baffle; 3. Shaft rod; 4. Connecting block; 5. Push plate; 6. Hydraulic mechanism of the ramming machine. Detailed Embodiment

[0012] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0013] As Figure 1 shown, a shaft rod baffle feeding hopper for a submerged arc furnace of ferroalloy includes a hopper 1. Both ends of the hopper 1 are open. One end is set as the discharge port, and the other end is provided with an extrusion port. A baffle 2 is arranged on the discharge port. The included angle between the bottom edge of the baffle 2 and the bottom surface of the hopper 1 is an acute angle. A shaft rod 3 is arranged on the top surface of the baffle 2. Connecting blocks 4 extending outward are symmetrically arranged at the top of the discharge port. The connecting blocks 4 are arranged on the outer wall of the discharge port. Through holes are formed in the connecting blocks 4. Both ends of the shaft rod 3 are inserted into the through holes. A push plate 5 is clamped in the extrusion port. The rear end wall of the push plate 5 is connected to the hydraulic mechanism 6 of the ramming machine. The four side walls of the push plate 5 and the baffle 2 are respectively attached to the inner walls of the extrusion port and the discharge port.

[0014] During operation, the hydraulic mechanism 6 of the ramming machine retracts, driving the push plate 5 to reset to the rear end of the hopper 1. At this time, the baffle 2 is in a closed state. After filling the hopper with materials, transportation is carried out. When it is transported into the submerged arc furnace, the hydraulic mechanism 6 of the ramming machine is started to push the push plate 5. The push plate 5 pushes into the hopper 1, extruding the materials to move towards the discharge port. The baffle 2 is lifted upward with the shaft rod 3 as the axis under the extrusion of the materials. The materials continue to be pushed by the push plate 5 and are discharged from the discharge port and fall into the submerged arc furnace. When the materials are emptied, the hydraulic mechanism 6 of the ramming machine retracts, the push plate 5 is retracted, and the baffle 2 returns to its initial state.
