Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for dust removal of metallurgical environmental protection flue gas, and in particular to a device for collecting flue gas during the casting of steel in mold casting vehicles. Background Technology

[0002] The production process of ingot casting includes multiple stages such as raw material preparation, smelting, casting, and post-processing. Among these, the casting process is the most critical step, affecting the quality and performance of the ingot. The casting process refers to the methods and techniques for pouring molten steel into ingots, including ladle casting and casting car casting.

[0003] Because steel casting trucks require mobile operations and continuously cast 2 to 3 steel ingot molds, the treatment of the fumes generated during steel casting trucks is currently a major challenge. Many companies do not collect and purify this fumes during production, and the few companies that do collect and purify them use roof hoods for fumes collection.

[0004] The existing special steel production workshop has a long casting production line and a wide distribution between steel ingot molds, resulting in the need for multiple roof covers for the casting span. The addition of multiple roof covers for capturing casting fumes from stainless steel steelmaking casting cars increases the load on the steel structure of the casting span. Installing dust collection hoods requires reinforcement of the plant, increasing project construction costs. The distance between the roof cover opening and the ladle casting opening is nearly 20 meters, resulting in low efficiency for direct fume capture. Roof cover capture can only solve the fume pollution within the fume plant, but cannot solve the fume pollution at the worker's work site. The dust collection system of the roof cover capture process requires a large air volume, leading to high energy consumption. Therefore, designing a casting fume capture device for ingot casting cars to solve the above technical problems is particularly important. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of increased load on the steel structure of the casting span due to the addition of multiple roof covers to the top of the existing factory building, the need to reinforce the factory building when setting up dust collection hoods, which increases the project construction cost, the low efficiency of direct flue gas capture, and the high air volume required by the existing roof cover dust collection technology dust collection system, which leads to high energy consumption of the dust collection system. Therefore, a flue gas capture device for casting steel car is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a casting fumes collection device for a casting car, comprising a casting car, rails on both sides of the casting car, symmetrically arranged slide rails at the bottom of the casting car, the casting car being slidably disposed in the slide rails, a steel ladle being disposed on the casting car, a drive beam being slidably mounted on the rails, a movable cover being mounted on the top of the drive beam, and a steel ingot mold being mounted below the casting car.

[0007] Preferably, an outlet pipe is provided at the top of the movable cover, and a movable trolley is provided at the side of the movable cover, the movable trolley being connected to the outlet pipe.

[0008] Preferably, the bottom of the mobile trolley is connected to a ventilation slot, and the top of the ventilation slot is connected to the mobile trolley.

[0009] Preferably, the mobile vehicle is a non-powered vehicle.

[0010] Preferably, the overall structure of the movable cover is located directly above the casting car.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, during use, the non-powered mobile trolley design relies on the natural movement of the mobile cover for synchronous movement, which simplifies the power requirements, thereby achieving the energy-saving goal and reducing the system's energy consumption. Workers can easily and flexibly move the mobile hood by operating it, eliminating the need for complicated operating procedures and greatly improving work efficiency and production safety. The flue gas capture device is used in heavy industrial environments such as steel plants, especially in situations where frequent casting operations generate large amounts of flue gas. It not only provides a flexible flue gas capture solution for multi-station and multi-location casting, but also effectively reduces air pollution through an efficient emission system, meeting environmental protection requirements. Compared with conventional flue gas capture devices that are fixed on the roof above the casting vehicle, the technical solution adopted by this utility model achieves dynamic capture of the flue gas generated during the casting process. It has high structural flexibility and is easy for workers to move. It solves the problems of existing factory buildings where adding multiple roof hoods increases the load on the steel structure of the casting span, requires factory building reinforcement when setting up dust collection hoods, increases project construction costs, has low efficiency in direct flue gas capture, and requires large air volumes for existing dust collection systems, resulting in high energy consumption.

[0013] 2. In this utility model, during use, the mobile trolley is located at the top of the ventilation duct and is driven by the movement of the mobile cover. With this design, there is no need to provide separate power for the mobile trolley. Instead, the movement trajectory of the mobile cover itself is used to drive its synchronous movement. This not only simplifies the equipment structure but also reduces additional energy consumption, achieving a highly efficient energy-saving effect. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] This utility model provides a fume collection device for casting steel pouring, including a casting car 1. Tracks 2 are provided on both sides of the casting car 1, and slide rails 3 are symmetrically arranged at the bottom of the casting car 1. The casting car is slidably mounted in the slide rails 3. A ladle 101 is mounted on the casting car 1. A drive beam 201 is slidably mounted on the track 2. A movable cover 202 is mounted on the top of the drive beam 201. A steel ingot mold 4 is mounted below the casting car 1. An outlet pipe 5 is provided at the top of the movable cover 202. A movable trolley 501 is provided on the side of the movable cover 202, and the movable trolley 501 is connected to the outlet pipe 5. A ventilation slot 502 is connected to the bottom of the movable trolley 501, and the top of the ventilation slot 502 is connected to the movable trolley 501.

[0020] In actual use, the fume collection device for the casting car has two additional tracks 2 on both sides of the casting car 1, along the direction of the two slide rails 3 used for the casting car's movement. These two tracks 2 serve as the travel path for the movable hood 202, ensuring that the movable hood 202 can move along the casting area of ​​the casting car 1. The movable hood 202 is located above the casting car 1, with a large coverage area that can completely cover the working area of ​​the casting car 1, thus ensuring effective fume collection. The movable hood 202 can be flexibly moved according to the casting position of the casting car by the operator to adapt to the fume collection of different casting positions. The upper part of the movable hood 202 is equipped with an outlet pipe 5, which is connected to a movable trolley 501 on the ventilation duct 502. The ventilation duct 502 is set on the side of the hood along the travel direction of the casting car 1 and uses a negative pressure system to... The fumes inside the hood are discharged. As the mobile hood 202 moves to different positions with the operation of the casting car 1, the mobile hood 202 drives the mobile trolley 501 to move synchronously along the ventilation slot 502, ensuring that the fumes inside the mobile hood 202 can always be effectively drawn into the ventilation system, maintaining continuous emission and treatment of the fumes. The mobile hood 202 can be flexibly adjusted according to different casting positions of the casting car 1, ensuring that the fumes generated at any casting position can be covered, improving the capture efficiency. Through the negative pressure extraction system and the precise coverage of the mobile hood 202, the high-temperature fumes generated during the casting process can be quickly and thoroughly captured and treated, reducing on-site air pollution. The design of the non-powered mobile trolley 501 relies on the natural movement of the mobile hood 202 for synchronous movement, simplifying the power requirements, thereby achieving the energy-saving goal and reducing the system's energy consumption. Workers can easily and flexibly move the movable hood 202 by operating it, without complicated operating procedures, which greatly improves work efficiency and production safety. The flue gas capture device is used in heavy industrial environments such as steel plants, especially in situations where frequent casting operations generate a large amount of flue gas. It not only provides a flexible flue gas capture solution for multi-station and multi-location casting, but also effectively reduces air pollution through an efficient emission system, meeting environmental protection requirements. Compared with conventional flue gas capture devices with a fixed structure set on the roof above the casting car 1, the technical solution adopted by this utility model achieves dynamic capture of the flue gas generated during the casting process, with high structural flexibility and easy movement by workers.

[0021] like Figure 1-2 As shown, the mobile trolley 501 is a non-powered trolley, and the overall structure of the mobile cover 202 is located directly above the casting car 1.

[0022] The effect achieved by the entire embodiment 1 is that, in use, the mobile trolley 501 is located at the top of the ventilation slot 502 and is driven by the movement of the mobile cover 202. With this design, there is no need to provide power to the mobile trolley 501 separately. Instead, the movement of the mobile cover 202 itself is used to drive its synchronous movement. This not only simplifies the equipment structure but also reduces additional energy consumption and achieves a highly efficient energy-saving effect.

[0023] Working Principle: On both sides of the casting car, two additional tracks are set along the direction of the two slide rails used for the casting car's movement. These two tracks serve as the travel path for the movable hood, ensuring that the movable hood can move along the casting area of ​​the casting car. The movable hood is located above the casting car, with a large coverage area that can completely cover the working area of ​​the casting car, thus ensuring effective capture of fumes. The movable hood can be flexibly moved according to the casting position of the casting car by the operator to adapt to the fumes capture of different casting positions. The upper part of the movable hood is equipped with an outlet pipe, which is connected to a moving trolley on the ventilation duct. The ventilation duct is set on the side of the hood along the direction of the casting car's movement and exhausts the fumes inside the hood through a negative pressure system. When the movable hood moves to different positions with the operation of the casting car, the movable hood drives the moving trolley to move synchronously along the ventilation duct, ensuring that the fumes inside the movable hood can always be effectively drawn into the ventilation system, maintaining continuous emission and treatment of fumes.
