Abstract
Description
Technical Field
[0001] This utility model relates to the field of coking equipment, specifically a device for preventing coke spillage on a coke blocking vehicle. Background Technology
[0002] Coking is crucial to steel production, involving the high-temperature dry distillation of coal in a coke oven to convert it into coke. Coke, as a vital raw material for steel production, plays a crucial role in subsequent ironmaking and steelmaking processes. During coking, coke is formed through prolonged heating and chemical reactions in the coke oven. Once mature, the coke needs to be removed from the oven; this process is called coke pushing. The equipment used for coke pushing includes a coke pusher car, a coke catcher car, and a coke quenching car located at the bottom of the coke catcher car. The coke catcher car includes a dust hood on its platform and a coke guide grid inside the dust hood. One end of the guide grid is connected to the coke oven. During coke pushing, the pusher car pushes the red-hot coke from the coke oven through the guide grid into the coke quenching car, while the dust hood removes dust simultaneously. However, due to the varying shapes and sizes of the coke and the dynamic effects during the pushing process, some coke inevitably spills onto the ground during its fall. This not only increases the labor intensity for workers but may also lead to a deterioration of the working environment, increased cleaning and maintenance costs, and even potential safety accidents such as fires.
[0003] To address this, utility model patent application number 2024212407130 discloses a device for preventing coke spillage from a coke quenching car. This device uses a baffle to intercept the red-hot coke falling from the coke guide grid outlet, thus preventing coke spillage. However, in practical applications, relying solely on a baffle for interception can easily lead to uneven distribution of red-hot coke, and there is a risk that the red-hot coke may roll off the opening of the coke quenching car when it is almost full, requiring improvement. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a device for preventing coke spillage in a coke blocking car.
[0005] To solve the above problems, the technical solution of this utility model is: a coke-blocking car anti-coke-sprinkling device, including a coke-blocking car platform and a dust removal hood installed below the coke-blocking car platform. The side of the dust removal hood is provided with a through groove, and a coke guide grid is installed inside the through groove. A coke-blocking component is installed inside the dust removal hood on the side away from the through groove.
[0006] The coke-blocking assembly includes multiple inclined coke-blocking plates, with a baffle strip fixed to the bottom of each coke-blocking plate. The coke-blocking plate has multiple through holes and is fixed to the inner wall of the dust collector by a support column.
[0007] The lower part of both sides of the dust removal hood is fixed with Z-shaped protective plates. The bending angle of the bent part of the protective plate is 90°. The two protective plates are engaged on both sides of the coke quenching car feed inlet.
[0008] Furthermore, the baffle bar and the scorch baffle are integrally formed, and the baffle bar is vertically arranged.
[0009] Furthermore, a positioning plate is fixedly connected to the end of the support column, and the scorch baffle is mounted on the positioning plate.
[0010] Furthermore, an inclined guide plate is installed at one end of the protective plate, and the included angle between the guide plate and the end of the protective plate is 50-75°.
[0011] Furthermore, a connecting plate is fixedly connected to the top of the guide plate, and one end of the connecting plate is detachably mounted on the protective plate by bolts.
[0012] The advantages of this utility model compared with the existing technology are as follows: the coke baffle plate of this utility model has multiple through holes, which can reduce the load on the coke baffle plate and improve the uniformity of red coke falling in the coke quenching car; the protective plate and the guide plate can further prevent red coke from spilling.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] like Figures 1 to 3As shown, a coke-preventing device for a coke-preventing car includes a coke-preventing car platform 1 and a dust removal hood 2 installed below the coke-preventing car platform 1. The dust removal hood 2 has a through groove on its side, and a coke guide grid 3 is installed inside the through groove. A coke-blocking component is installed inside the dust removal hood 2 on the side away from the through groove.
[0019] The coke-blocking assembly includes multiple inclined coke-blocking plates 4. A baffle strip 5 is fixedly connected to the bottom of the coke-blocking plate 4. Multiple through holes are opened on the coke-blocking plate 4, and the coke-blocking plate 4 is fixed to the inner wall of the dust collector hood 2 by a support column 6. The baffle strip 5 and the coke-blocking plate 4 are integrally formed, and the baffle strip 5 is vertically arranged. A positioning plate 8 is fixedly connected to the end of the support column 6, and the coke-blocking plate 4 is installed on the positioning plate 8.
[0020] The setting of the coke baffle plate 4 can effectively block the red coke pushed out by the coke guide grid 3 outlet, and prevent coke from spilling. The coke baffle plate 4 has multiple through holes, which allow some coke to fall into the coke quenching car through the through holes, reducing the load on the coke baffle plate 4 and improving the uniformity of the red coke falling into the coke quenching car.
[0021] Stop adding red coke to the quenching car when the red coke level inside reaches position 5 (stop adding red coke to avoid excessive red coke).
[0022] The dust collector hood 2 has Z-shaped protective plates 7 fixedly attached to the lower parts of both sides. The bending angle of the bent part of the protective plate 7 is 90°. The two protective plates 7 are engaged on both sides of the coke quenching car inlet. An inclined guide plate 9 is installed at one end of the protective plate 7. The included angle between the guide plate 9 and the end of the protective plate 7 is 60°. A connecting plate 10 is fixedly attached to the top of the guide plate 9. One end of the connecting plate 10 is detachably installed on the protective plate 7 by bolts. The guide plate 9 is located at the rear end of the coke quenching car in the forward direction.
[0023] The width of the dust hood 2 is smaller than the width of the feed inlet of the coke quenching car. When combined with the protective plate 7, it can effectively prevent the red coke from spilling during and after the material is dropped. When the coke quenching car moves forward, the guide plate 9 can push the red coke at the edge of the coke quenching car inward to further prevent the red coke from spilling.
[0024] In practical use, during the coking process, the coking car pushes the red coke in the coke oven through the coke guide grid 3 and pushes it into the quenching car. During the fall of the red coke, the coke baffle 4 catches the falling red coke and prevents it from spilling onto the ground. The coke baffle 4 has multiple through holes, which allow some coke to fall into the quenching car through the through holes, reducing the load on the coke baffle 4 and improving the uniformity of the red coke falling into the quenching car. The protective plate 7 can prevent the red coke from spilling, and the guide plate 9 can push the red coke at the edge of the quenching car inward to further prevent the red coke from spilling.
