Description

Technical Field

[0001] This utility model belongs to the field of dust collection technology for coke oven equipment, specifically relating to a dust collection hood device for a coke quenching car. Background Technology

[0002] As an important piece of equipment in the modern iron and steel smelting industry, the coke oven's main function is to convert coal into coke through high-temperature treatment for use in subsequent ironmaking processes. This process involves several complex operational steps, with coke pushing and coke receiving being two particularly critical stages. Coke pushing refers to pushing the pyrolyzed coke out of the coke oven, while coke receiving involves using a coke catcher to catch the pushed-out coke and transport it to a designated location. In actual production, when the furnace door is opened and the coke is pushed out, a large amount of dust and smoke is instantly generated above the furnace door. This dust not only contains harmful substances, posing a threat to the health of the operators, but also seriously pollutes the surrounding environment.

[0003] In existing technologies, the traditional approach to address this problem is to install a fixed dust collection hood above the coke oven opening of the quenching car. This hood uses negative pressure suction to draw the generated dust into a pipe, where it is then processed by a dust removal device before being released into the atmosphere. Since large coke ovens are typically equipped with oven door maintenance vehicles for regular maintenance and repair of the oven doors, and these vehicles usually have tracks located on the oven column brackets above the opening, they must pass in front of the quenching car without interfering with it or the dust collection hood. To meet this requirement, the fixed dust collection hood is often designed to be located far from the oven opening. While this avoids interference with the maintenance vehicle, it also prevents the hood from effectively covering the dust-generating area, significantly reducing its dust collection efficiency. Therefore, there is an urgent need for a dust collection hood device for coke ovens. Utility Model Content

[0004] To address some or all of the technical problems existing in the prior art, this utility model provides a dust collection hood device for a coke quenching car.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1 to 5As shown, this utility model discloses a dust collection hood device for a coke quenching car. The dust collection hood device is installed on the top of the coke quenching car 1 near the furnace column 2, between the coke quenching car 1 and the furnace column 2. A baffle plate 3 matching the dust collection hood device is installed on the furnace column 2. A maintenance vehicle track 5 is provided between the furnace column 2 and the dust collection device. The maintenance vehicle (not shown in the figure) can slide to the front of the furnace column 2 via the maintenance vehicle track 5 to inspect and maintain the furnace door. The dust collection device includes multiple sets of support rollers 4 installed on the top of the coke quenching car 1, support plates 6 respectively installed on both sides of the multiple sets of support rollers 4 and fixed to the top of the coke quenching car 1, a telescopic cover 8 installed between two support plates 6, and guide rollers 7 installed inside the support plates 6. The support rollers 4 provide horizontal support for the movement of the telescopic cover 8, and the guide rollers 7 provide lateral support for the movement of the telescopic cover 8 to prevent the telescopic cover 8 from deviating during the movement. The telescopic hood 8 is slidably connected to the inner side of the support plate 6 via guide rollers 7 on the outside, and to the top of the coke quenching car 1 via support rollers 4 on the bottom. A dust extraction fan 10 is installed at the end of the telescopic hood 8 away from the furnace column 2. The dust extraction fan 10 is connected to a dust extraction pipe (not shown in the figure). The negative pressure generated by the dust extraction fan 10 draws the smoke and dust into the dust extraction pipe. Then, the dust extraction pipe will transmit the air containing the smoke and dust to the dust collector (not shown in the figure) for filtration and discharge into the atmosphere. The dust extraction pipe is located below the telescopic hood 8. A hydraulic cylinder 9 is fixedly installed above the coke quenching car 1. The hydraulic cylinder 9 includes a cylinder barrel fixed above the coke quenching car 1 via a fixing frame 11 and a push rod slidably sleeved in the cylinder barrel. The free end of the push rod is fixed to the telescopic hood 8. One end of the telescopic hood 8 is matched with the smoke baffle 3. When the push rod extends, the telescopic hood 8 approaches the furnace column 2 and matches the smoke baffle 3 to form a closed space. When the push rod retracts, the telescopic hood 8 moves away from the furnace column 2 and returns to its initial state.

[0021] In one specific embodiment, the dust collection hood device for a coke quenching car of this utility model has 3 to 6 supporting rollers 4. More specifically, the number of supporting rollers 4 is 3. Of course, the specific number and distribution position of the supporting rollers 4 need to be determined according to the specific working conditions such as the shape and size of the telescopic hood 8 during actual use.

[0022] Furthermore, in the dust collection hood device for the coke quenching car of this utility model, the telescopic hood 8 is parallel to the top plane of the coke quenching car 1. This arrangement improves the overall dust collection efficiency of the device.

[0023] As a specific embodiment, in the dust collection hood device for coke quenching car of this utility model, a heat-resistant plate (not shown in the figure) is provided at one end of the telescopic hood 8 near the furnace column 2. The heat-resistant plate is made of high temperature resistant material. This arrangement is to prevent the telescopic hood 8 from being damaged or deformed due to high temperature after contacting the smoke baffle 3, thereby improving the durability and safety of the device.

[0024] The working principle of the dust collection hood device for coke quenching cars of this utility model is as follows:

[0025] In the non-working state, the telescopic cover 8 retracts to its initial position under the action of the hydraulic cylinder 9. At this time, the telescopic cover 8 will not block the passage of the maintenance car, thus avoiding interference with the maintenance car. When entering the working state, the push rod of the hydraulic cylinder 9 pushes the telescopic cover 8 to slide along the support plate 6 and the guide roller 7, so that it extends and fits against the smoke baffle 3 of the furnace column 2. In this way, a closed space is formed between the telescopic cover 8 and the smoke baffle 3, which effectively seals the smoke and dust inside. At the same time, the dust suction fan 10 is started. The dust suction fan 10 sucks the smoke and dust in the closed space into the dust collector through the dust suction pipe and performs centralized treatment, thus completing the dust collection work of the coke quenching car 1.

[0026] In summary, compared with the prior art, the dust collection hood device for coke ovens of this invention has the following advantages and beneficial effects:

[0027] This device has a simple structure and is easy to use. It achieves mobility by setting up components such as hydraulic cylinder 9, telescopic cover 8, support roller 4 and guide roller 7. It can avoid interference with maintenance vehicles when not in operation. When in operation, it forms a closed space with the furnace column 2 and smoke baffle 3 to efficiently collect smoke and dust. It has the advantages of strong stability, high durability, strong adaptability and significant environmental benefits. It effectively reduces dust and smoke pollution in the coke oven production process, improves the environmental protection level and has good practicality.
