Description

Technical Field

[0001] This utility model relates to the field of coking equipment technology, and in particular to coking preparation equipment. Background Technology

[0002] Coke is a type of solid fuel obtained by dry distillation of coal under high temperature conditions. After coke production, it needs to be pushed out of the coking oven and randomly transported to cooling equipment. During the transport process, the coke will also undergo a certain degree of natural cooling. After entering the cooling equipment, cooling water is sprayed onto the coke to achieve rapid cooling. After cooling, moisture will adhere to the surface of the coke, so it needs to be dried to keep it dry. However, in existing coke production equipment, the cooling and drying of coke need to be carried out in different equipment, which requires the coke to be transferred between the equipment. This seriously affects the efficiency of coke production and brings great inconvenience to the coking process. Utility Model Content

[0017] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application 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 scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-3 As shown, the coke preparation equipment described in this embodiment includes a processing tank 1. A feed inlet 2 is provided at the top of the processing tank 1, and a discharge outlet 3 is provided on one side of its lower end. Several inclined downward-arranged grid plates 4 are provided on both sides of the inner wall of the processing tank 1, with adjacent grid plates 4 facing opposite directions. One end of each grid plate 4 is fixedly connected to the inner wall of one side of the processing tank 1, and a material passage gap exists between the other end of each grid plate 4 and the inner wall of the other side of the processing tank 1. The feed inlet 2 corresponds to the position of the top grid plate 4. A cooling device is provided inside the processing tank 1 above the corresponding top grid plate 4. The cooling pipe 5 has several water outlets 6 on the side facing the top grid plate 4. The lower end of the treatment tank 1 is provided with an inclined guide grid 7 at the position corresponding to the discharge port 3. The lowest point of the inclined guide grid 7 corresponds to the lower edge of the discharge port 3. The treatment tank 1 is also provided with a protective cover 8 below the corresponding grid plate 4. The protective cover 8 is provided with air holes 9 evenly distributed. The side wall of the treatment tank 1 is provided with holes 10 corresponding to the cavity inside the protective cover 8. The outside of the treatment tank 1 is provided with a drying pipe 11 that can move along the holes 10 into the protective cover 8. The drying pipe 11 is provided with several air outlets 12 evenly distributed.

[0020] The protective cover 8 has a triangular cross-section, with one end of the protective cover 8 with a sharp corner facing upwards, and the end of the protective cover 8 with an opening installed at the position of the corresponding hole 10. The air vent 9 is set on the two inclined side walls of the protective cover 8.

[0021] The protective cover 8 has several drainage holes 13 evenly distributed on its bottom wall.

[0022] An installation plate 14 is provided on the outside of the treatment tank 1 at the position corresponding to the drying pipe 11. A multi-stage electric cylinder 15 is provided on the installation plate 14. The piston rod of the multi-stage electric cylinder 15 is fixedly connected to the end of the drying pipe 11. The drying pipe 11 moves into the protective cover 8 under the drive of the multi-stage electric cylinder 15. An air inlet 16 is provided at the end of the drying pipe 11 located outside the treatment tank 1. The air inlet 16 is connected to the air supply equipment through a pipeline.

[0023] The diameter of the hole 10 is larger than the diameter of the drying tube 11. A sealing block 17 is provided on the outer side of one end of the drying tube 11 and the multi-stage electric cylinder 15, and the sealing block 17 seals the hole 10.

[0024] The arrangement of the protective cover 8 allows the drying tube 11 to move normally within the processing tank 1, preventing coke from obstructing its movement. When cooling is required, the drying tube 11 is moved out of the processing tank 1, preventing cooling water from entering the protective cover 8 and wetting the drying tube 11, thus avoiding corrosion and extending its service life.

[0025] Discharge valves 18 are installed at the discharge ports 3.

[0026] The top of the treatment tank 1 is also equipped with an exhaust pipe 19, which is used to discharge water mist generated by cooling and hot air generated by drying. The exhaust pipe 19 is connected to the flue gas treatment equipment through a pipeline so that the flue gas is treated and then discharged.

[0027] The bottom of the treatment tank 1 is also equipped with a drain pipe 20, and a drain valve 21 is installed on the drain pipe 20.

[0028] The bottom of the treatment tank 1 has a constricted structure, and the drain pipe 20 is located at the bottom end of the constricted structure.

[0029] The working principle of this utility model is as follows: First, driven by the multi-stage electric cylinder 15, the drying pipe 11 is moved out of the processing tank 1. At the same time, coke is conveyed into the processing tank 1 through the feed inlet 2 via the conveying equipment. The coke falls onto the grid plate 4 inside the processing tank 1 and is continuously turned and conveyed. As the coke enters the processing tank 1, the water outlet 6 on the cooling pipe 5 sprays cooling water onto one side of the coke for cooling. The coke eventually falls onto the guide grid 7 and accumulates continuously inside the processing tank 1. Excess cooling water drips down the grid plate 4 and the holes in the guide grid 7 to the bottom of the processing tank 1. The cooling water entering the protective cover 8 flows down the bottom... The drain hole 13 on the plate drains outward to prevent cooling water from accumulating inside the protective cover 8. After the coke is cooled, the multi-stage electric cylinder 15 controls the drying pipe 11 to move into the interior of the protective cover 8. Thus, the drying pipe 11 enters the interior of the processing tank 1. The hot air supply equipment sends hot air into the drying pipe 11 through the pipeline and the air inlet 16. The hot air is sent out through the air outlet 12 on the drying pipe 11 and the air hole 9 on the protective cover 8. The hot air enters the interior of the processing tank 1 and dries the damp coke. After cooling and drying, the discharge valve 18 is opened, and the coke will be discharged outward through the discharge port 3. The drain valve 21 is opened to recover the dripping cooling water.

[0030] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
