Description

Technical Field

[0001] This utility model relates to the field of material recycling technology used in steelmaking production, specifically a material recycling device for steelmaking. Background Technology

[0002] Alloys, fluxes and other materials are the most important raw materials in steelmaking. They are used in large quantities in daily production and also generate a lot of quicklime, lightly burned dolomite, alloy ash and waste materials. Due to the lack of suitable recycling devices, waste occurs. Material recycling also has problems such as large amounts of dust, inconvenient recycling and transportation, and inconvenient recycling and use.

[0003] According to a public notice (Announcement No.: CN218319606U) of a steelmaking material recycling device, the above application includes a vertical pipe, a dust cover, and a material hopper. The vertical pipe is set above the material hopper, and the bottom end of the vertical pipe is connected to the dust cover. Rotating shaft seats are fixed on the outer walls of both sides of the lower part of the material hopper. A fixed hanging ring is fixedly connected to one side of the material hopper. A hook is provided on the outside of the material hopper, and the hook is hooked and connected to the fixed hanging ring.

[0004] However, in actual use, there is a gap between the dust cover and the material hopper in the above-mentioned recycling device. The gap will still allow fine materials such as lime, alloy ash or lightly calcined dolomite powder generated during the steelmaking process to leak into the environment from between the dust cover and the material hopper during the recycling process, resulting in increased dust concentration in the workplace and pollution of the production environment. In view of this, we propose a recycling device for steelmaking materials. Utility Model Content

[0005] The purpose of this invention is to provide a material recycling device for steelmaking, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steelmaking material recycling device, comprising a vertical pipe, a recycling component at the bottom of the vertical pipe, the recycling component including a guide rail fixedly connected to the bottom of the vertical pipe, a guide block fixedly connected to the inner wall of the vertical pipe, the guide rail being slidably connected to a material hopper, a receiving bag fixedly connected to the inner wall of the material hopper, a baffle slidably connected to the inner wall of the material hopper, and a handle hinged to the side wall of the baffle.

[0007] Preferably, one end of the receiving bag is fixedly connected to the inner wall of the material hopper, and the other end of the receiving bag is fixedly connected to the bottom end face of the baffle, so that the receiving bag collects and recycles the material.

[0008] Preferably, the guide block is located at the bottom of the vertical pipe where the discharge port is aligned with the top of the material hopper where the inlet is aligned, and the top of the guide block is provided with an arc-shaped surface.

[0009] Preferably, the vertical pipe has an opening on its side wall, the opening being located above the vertical pipe. The vertical pipe is fixedly connected to a conveying device, which feeds material into the vertical pipe through the opening, and then the material falls into the receiving bag.

[0010] Preferably, a square tube is fixedly connected to the bottom of the material hopper, and two sets of the square tubes are arranged symmetrically at the bottom of the material hopper.

[0011] Preferably, the recycling assembly further includes an air inlet pipe fixedly connected to the side wall of the vertical pipe, a fan fixedly connected to the inner wall of the air inlet pipe, and ventilation holes provided on the side wall of the material hopper to allow the blown-in air to be discharged normally.

[0012] Preferably, a guide plate is fixedly connected to the inner wall of the vertical pipe, and the guide plate is disposed at one end of the air intake pipe located on the inner wall of the vertical pipe.

[0013] Compared with the prior art, this utility model provides a material recovery device for steelmaking, which has the following beneficial effects: 1. This steelmaking material recovery device, through its recovery components, includes a baffle that seals the feed inlet after the material hopper is full, forming a sealed collection structure with the containment bag to prevent dust and powder from overflowing, thus improving the cleanliness of the recovery process. The negative pressure airflow draws in external air through the opening and blows it into the containment bag along the airflow direction, promoting concentrated material collection and further preventing dust diffusion. It sucks in slightly suspended or dusty materials into the containment bag, preventing dust from scattering, reducing the dust concentration in the workshop air, reducing the health risk of operators inhaling dust, and improving the working environment.

[0014] 2. The steelmaking material recovery device uses a guide plate to guide airflow through one end of the guide plate fixed to the inner wall of the vertical pipe. The airflow is directed downwards, causing slightly suspended or dusty materials to be concentrated and sucked into the collection bag by the negative pressure airflow. This prevents the upward airflow from disturbing the material and causing it to scatter or bounce, thus improving the recovery rate. Attached Figure Description

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a steelmaking material recycling device, including a vertical pipe 1, a recycling component 2 at the bottom of the vertical pipe 1, the recycling component 2 including a guide rail 201 fixedly connected to the bottom of the vertical pipe 1, a guide block 202 fixedly connected to the inner wall of the vertical pipe 1, the guide rail 201 being slidably connected to a material hopper 203, a receiving bag 204 fixedly connected to the inner wall of the material hopper 203, a baffle 205 slidably connected to the inner wall of the material hopper 203, and a handle 206 hinged to the side wall of the baffle 205.

[0018] In one embodiment of this utility model, one end of the receiving bag 204 is fixedly connected to the inner wall of the material hopper 203, and the other end of the receiving bag 204 is fixedly connected to the bottom end face of the baffle 205. The receiving bag 204 collects and recycles the material. The discharge port of the guide block 202 at the bottom of the vertical pipe 1 is aligned with the inlet at the top of the material hopper 203. The top of the guide block 202 is provided with an arc-shaped surface. An opening 5 is opened on the side wall of the vertical pipe 1. The opening 5 is located above the vertical pipe 1. The vertical pipe 1 is fixedly connected to the conveying device. The conveying device puts the material into the vertical pipe 1 through the opening 5, and then the material falls into the receiving bag 204.

[0019] The recycling component 2 also includes an air inlet pipe 207 fixedly connected to the side wall of the vertical pipe 1. A fan 208 is fixedly connected to the inner wall of the air inlet pipe 207. The side wall of the material hopper 203 is provided with ventilation holes so that the blown air can be discharged normally. A square tube 3 is fixedly connected to the bottom of the material hopper 203. Two sets of square tubes 3 are provided and symmetrically arranged at the bottom of the material hopper 203.

[0020] First, slide the material hopper 203 along the guide rail 201 into the bottom of the vertical pipe 1, aligning the top inlet of the material hopper 203 with the bottom outlet of the vertical pipe 1. The arc-shaped surface of the guide block 202 guides the falling material smoothly into the material hopper 203. The operator pushes the handle 206 to move the baffle 205 away from above the inlet of the material hopper 203, opening the collection channel of the receiving bag 204. When the conveying device puts the material into the vertical pipe 1 through the opening 5, the material falls into the receiving bag 204 under the action of gravity, guided by the guide block 202. One end of the receiving bag 204 is fixed to the inner wall of the material hopper 203. The other end is fixedly connected to the bottom end face of the baffle 205 to realize the material collection and temporary storage functions. When the receiving bag 204 is full of material, the operator pulls the handle 206 to make the baffle 205 block the feed inlet and close the receiving bag 204, isolating the collected material from the feed inlet and completing the closed material recycling process. The material hopper 203 can then slide out from the guide rail 201 to facilitate the handling or subsequent processing of the collected material. The baffle 205 can close the feed inlet after the material hopper 203 is full, forming a closed collection structure with the receiving bag 204 to prevent dust and powder from overflowing and improve the environmental cleanliness of the recycling process.

[0021] Air is blown into the vertical pipe 1 through the air intake pipe 207 via the fan 208. The air velocity inside the vertical pipe 1 is greater than that of the external environment, thus creating a negative pressure state inside the vertical pipe 1. Since the material hopper 203 has ventilation holes on its side wall, air can be discharged from the ventilation holes, thereby ensuring smooth airflow. After the conveying device puts the material into the vertical pipe 1 through the opening 5, the material falls into the receiving bag 204 along the guide block 202 under the action of gravity. At the same time, the negative pressure airflow draws in the external air through the opening 5 and blows it into the receiving bag 204 along the airflow direction, promoting the concentrated collection of materials and further preventing dust diffusion. Slightly suspended or dusty materials are sucked into the receiving bag 204 to avoid dust scattering. The dust concentration in the workshop air is reduced, reducing the health risk of operators inhaling dust and improving the working environment.

[0022] In addition, a guide plate 4 is fixedly connected to the inner wall of the vertical pipe 1. The guide plate 4 is set at one end of the air inlet pipe 207 located on the inner wall of the vertical pipe 1. The air inlet pipe 207 blows air into the vertical pipe 1 through the fan 208. The air flows through the guide plate 4 fixed at one end of the inner wall of the vertical pipe 1 and is guided downward. This causes slightly suspended or dusty materials to be concentrated and sucked into the collection bag 204 by the negative pressure airflow. This prevents the upward air from disturbing the material and causing the material to scatter or rebound, thereby improving the recovery rate and the stability and safety of the system operation.

[0023] In this invention, during use, the material hopper 203 is slid along the guide rail 201 into the bottom of the vertical pipe 1, aligning the top inlet and outlet. The arc-shaped surface of the guide block 202 guides the material smoothly into the receiving bag 204. The operator pushes the handle 206 to open the baffle 205 collection channel, and the conveying device feeds the material into the vertical pipe 1 through the opening 5. Under the action of gravity, the material falls into the receiving bag 204 along the guide block 202. At the same time, the air inlet pipe 207 blows air in through the fan 208, creating a negative pressure inside the vertical pipe 1. Excess air is discharged through the vent, and the negative pressure draws in external air and blows it into the receiving bag 204, causing slightly suspended or dusty materials to be collected in a concentrated manner, preventing dust from scattering. When the receiving bag 204 is full, the handle 206 is pulled to close the baffle 205, closing the receiving bag 204 and achieving sealed material recovery, which is convenient for handling or subsequent processing. At the same time, it reduces the dust concentration in the workshop, improves the operating environment, and increases the recovery efficiency and environmental cleanliness.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
