AI Technical Summary
In existing technologies, insufficient water or excessive local moisture content during the coal charging process in tamping coke ovens leads to low coal cake integrity, resulting in reduced coke oven output.
A spray pipe and mist nozzle device are used to evenly spray water mist directly above the tamping coke oven's shaking feeder. The moisture content is adjusted by a control valve to ensure uniform moisture content in the coal cake and prevent coal collapse.
It improves the integrity of tamped coal cakes, reduces coal collapse, and increases coke production.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of coke oven charging technology, specifically relating to a device for stabilizing the moisture content of coal cakes charged into a coke oven. Background Technology
[0002] With the continuous development of steel enterprises, the scale of coke oven construction has expanded rapidly. However, due to the limited coal resources, the proportion of tamped coke ovens has increased significantly during the construction process. The main purpose of constructing tamped coke ovens is to improve the quality and output of coke using limited coal resources. In the existing technology of coke oven coal charging, the low water content or local high moisture content will lead to a certain amount of coal collapse in the coal cake, resulting in a low integrity of the coal cake and thus a low output of coke oven.
[0003] Therefore, it is necessary to design a device to stabilize the moisture content of the coal cake fed into the coke oven, which can achieve uniform and effective spraying directly above the material, avoid localized high moisture content causing an increase in the coal cake collapse rate, and stabilize the moisture content of the coal cake. Utility Model Content
[0004] In view of the problems of the prior art, the purpose of this utility model is to provide a device for stabilizing the moisture content of coal cakes fed into coke ovens, so as to solve the problem of low integrity of coal cakes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A device for stabilizing the moisture content of coal cake fed into a tamping coke oven includes a production water pressure tank connected to a spray pipe. The other end of the spray pipe is connected to a spray pipe with a plurality of mist nozzles. The spray pipe is installed directly above the tamping coke oven shaking feeder, and the mist nozzles are positioned directly above the center of the feed inlet of the tamping coke oven shaking feeder.
[0007] More preferably, the number of mist nozzles matches the number of feed ports.
[0008] More preferably, the spray piping is equipped with control valve I and control valve II.
[0009] More preferably, the control valve I and control valve II are connected to an operating platform, and the operating platform controls the opening degree of the control valve I and control valve II.
[0010] More preferably, the production water pressure tank is located above the spray pipe.
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] This invention utilizes water mist sprayed from a mist nozzle to adjust the moisture content of materials during the feeding process. The mist nozzle enables uniform and effective spraying directly above the material, preventing localized high moisture content from increasing the collapse rate of the compacted coal cake, stabilizing the moisture content of the compacted coal cake, ensuring the integrity of the compacted coal cake, reducing the amount of collapsed coal during coke oven charging, and increasing coke production.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0016] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a number" means two or more, unless otherwise explicitly specified.
[0017] like Figure 1 As shown, a device for stabilizing the moisture content of coal cake fed into a coke oven includes a production water pressure tank 1 and an operating platform 4. The production water pressure tank 1 is connected to a spray pipe 2. The spray pipe 2 is equipped with a control valve I3 and a control valve II5. Control valve I3 controls the water outlet of the production water pressure tank 1, and control valve II5 controls the water inlet of the spray pipe 6 and the mist nozzles 7. The operator controls the opening of control valve I3 and control valve II5 through the control platform 4. The other end of the spray pipe 2 is connected to the spray pipe 6, which is installed directly above the coke oven shaking feeder. The spray pipe 6 is equipped with a number of mist nozzles 7, the number of which matches the number of feed inlets. The mist nozzles 7 are directly facing the center of the feed inlets and pointing towards the material.
[0018] The production water from the coking oven area is drawn to the coking oven tamping station and stored in the production water pressure tank 1. Pipes are then installed above the feeding ports of the tamping oven shaking feeders (10 each for coking ovens #5 and #6). Spray pipes 6 are connected to the pipes above each shaking feeder. Under the influence of gravity due to the height difference between the production water pressure tank 1 and the feeder, the production water flows along the spray pipes 2 into each mist nozzle 7. During the feeding process of the coal at the feeding port, control valves I3 and II5 are opened. The operator controls the opening degree of control valves I3 and II5 through the control platform 4 as needed. The mist nozzles 7 spray directly above the material, evenly increasing the moisture content of the material during the discharge process and adjusting it in real time to stabilize the moisture content of the tamped coal cake, ensuring the integrity of the tamped coal cake, reducing coal collapse during coking oven charging, and increasing coke production.
[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, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
