Abstract
Description
Technical fields:
[0001] This utility model belongs to the field of mechanical clarification tank production, and particularly relates to a coking mechanical clarification tank. Background technology:
[0002] A mechanized ammonia clarification tank is a type of primary cooling equipment for coke oven gas that uses gravity settling to separate coal tar, ammonia, and tar residue. Its tank cross-section can be boat-shaped or rectangular. Mechanized ammonia clarification tanks are used by gas companies or coking plants to purify coal tar. They primarily separate tar, ammonia, and tar residue based on the difference in specific gravity of the materials. The tank consists of three layers: an upper layer of ammonia, a middle layer of tar, and a lower layer of tar residue. The tar residue settled at the bottom is conveyed by a scraper conveyor to a drain nozzle and discharged from the tank. The tar flows to the tar tank through a level regulator, and the clarified ammonia overflows from the top into a circulating ammonia tank.
[0003] The tar residue separated by the mechanical clarification tank in the coal coking plant is discharged into the slag collection truck through the slag discharge pipe and transported away. During this process, after the slag is discharged, the tar carried by the tar residue will adhere to the inner wall of the slag discharge pipe and drip down the pipe wall onto the ground, causing pollution and damage to the environment of the working site. At the same time, the dripping tar cannot be recovered in time, resulting in waste of resources. Summary of the Invention:
[0004] The purpose of this invention is to provide a coking mechanical clarification tank, which overcomes the shortcomings of the prior art and effectively solves the existing problem of tar dripping and polluting the environment.
[0005] The present invention relates to a coking mechanical clarification tank, comprising a mechanical clarification tank body, a slag discharge pipe provided at one end of the mechanical clarification tank body, a frame-shaped tar collection groove provided at the bottom end of the slag discharge pipe, the bottom end of the slag discharge pipe extending into the inner cavity of the frame-shaped tar collection groove, and the frame-shaped tar collection groove and the slag discharge pipe being fixedly connected by a strip.
[0006] Furthermore, the top of the inner wall of the frame-shaped tar collection groove bends toward the inner wall of the slag discharge pipe.
[0007] Furthermore, the gap between the top of the inner wall of the frame-shaped tar collection groove and the inner wall of the slag discharge pipe is less than 2 cm.
[0008] Furthermore, an oil guide pipe is connected to the frame-shaped tar collection groove, and the output end of the oil guide pipe is connected to the oil storage tank.
[0009] The beneficial effects of this utility model are as follows: by matching and setting a frame-shaped tar collection groove directly below the slag discharge pipe, the tar dripping from the slag discharge pipe can be blocked and recovered in time, which not only protects the working environment, but also avoids waste of resources.

[0012] Figure 3 for Figure 2 Cross-sectional view of section BB;
[0013] In the diagram, 1 is the mechanical clarification tank, 2 is the slag discharge pipe, 3 is the frame-shaped tar collection groove, 4 is the slats, 5 is the oil guide pipe, and 6 is the oil storage tank. Detailed implementation method:
[0014] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:
[0015] like Figures 1 to 3 As shown, a coking mechanical clarification tank includes a mechanical clarification tank body 1. A slag discharge pipe 2 is provided at one end of the mechanical clarification tank body 1. A frame-shaped tar collection groove 3 is provided at the bottom end of the slag discharge pipe 2. The bottom end of the slag discharge pipe 2 extends into the inner cavity of the frame-shaped tar collection groove 3. The frame-shaped tar collection groove 3 and the slag discharge pipe 2 are fixedly connected by a strip 4. The top end of the inner sidewall of the frame-shaped tar collection groove 3 is bent towards the inner sidewall of the slag discharge pipe 2. The gap between the top end of the inner sidewall of the frame-shaped tar collection groove 3 and the inner sidewall of the slag discharge pipe 2 is less than 2 cm. An oil guide pipe 5 is connected to the frame-shaped tar collection groove 3, and the output end of the oil guide pipe 5 is connected to an oil storage tank 6.
[0016] Specifically, by matching the frame-shaped tar collection groove 3 directly below the slag discharge pipe 2, the tar dripping from the slag discharge pipe 2 can be blocked and recovered in a timely manner.
[0017] In actual use, the frame-shaped tar collection groove 3 is connected and fixed to the slag discharge pipe 2 by the strip 4. When discharging slag, the tar slag falls freely from the slag discharge pipe 2 and passes through the opening formed by the frame-shaped tar collection groove 3 and finally falls into the slag collection car. The tar adhering to the inner wall of the slag discharge pipe 2 flows down the pipe wall under the action of gravity. When the tar flows to the lowest point, it drips into the inner cavity of the frame-shaped tar collection groove 3. When a certain amount of tar is collected, it flows from the oil guide pipe 5 into the oil storage tank 6 for temporary storage.
[0018] The top of the inner wall of the frame-shaped tar collecting groove 3 bends toward the inner wall of the slag discharge pipe 2, and the gap between the two is less than 2cm. This not only allows the tar to drip smoothly into the inner cavity of the frame-shaped tar collecting groove 3, but also helps the tar residue to slide quickly off the inner wall of the frame-shaped tar collecting groove 3, preventing the gap from becoming blocked.
[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
