Description

Technical Field

[0001] The utility model relates to the technical field of coking furnaces, in particular to a high-temperature coking discharging device. Background Art

[0002] The coking box furnace ignites the coal by injecting air into the furnace. As the temperature rises, the volatile substances in the coal begin to be released and pyrolyzed in an oxygen-deficient environment, eventually turning into coke. After the coal is coked at high temperature, the discharging device will be used to push the coke out of the furnace;

[0003] The discharge device, driven by a driving device such as a hydraulic rod, will move in the oven through a pusher head, come into contact with the coke and exert a thrust to push the coke toward the discharge port of the coke oven;

[0004] The following problems were found during the actual use of the above-mentioned discharging device:

[0005] When the coke pushing head pushes coke for a long time, the bottom surface of the coke pushing head will be worn continuously, which will cause the coke pushing effect of the discharging device to decline and fail to push the coke effectively, which may cause the equipment to jam or be damaged.

[0006] The coke pushing part of the discharge device works in the high temperature environment of the furnace for a long time, and the metal parts may suffer from thermal fatigue, resulting in breakage or deformation.

[0007] In summary, there is a need for a high-temperature coking discharging device that can cope with wear and high temperature. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] In order to solve the technical problems in the background technology, a high-temperature coking discharging device is provided as follows:

[0030] Combination Figure 1-Figure 5As shown, a high-temperature coking discharging device provided by the utility model comprises a coke pushing plate 1 and a supporting plate 2, a connecting block 21 is provided on the side of the supporting plate 2, a plurality of connecting blocks 21 are provided on the side of the supporting plate 2, the connecting block 21 is fixedly connected to the coke pushing plate 1, a coke pushing assembly 5 is provided on the bottom surface of the coke pushing plate 1, a sliding mechanism 4 is provided on the edge of the coke pushing plate 1 and the edge of the supporting plate 2, the sliding mechanism 4 can improve the stability of the coke pushing plate 1 and the supporting plate 2 when they move, a cooling mechanism 3 for cooling and lowering the temperature is provided inside the coke pushing plate 1, a mounting groove 11 is provided on the bottom surface of the coke pushing plate 1, a plurality of mounting grooves 11 are provided at equal intervals on the bottom of the coke pushing plate 1, the mounting groove 11 is in a T-shaped structure, and the mounting groove 11 The auxiliary coke pushing assembly 5 can be assembled and fixed at the bottom of the coke pushing plate 1. The coke pushing assembly 5 includes a coke pushing head 51 and a mounting block 52. The side of the coke pushing head 51 is provided with a mounting block 52. The mounting block 52 is fixedly arranged on the side of the coke pushing head 51. The mounting block 52 is arranged corresponding to the mounting groove 11. The mounting block 52 and the mounting groove 11 are engaged and slid. Through the engagement of the mounting block 52 and the mounting groove 11, when the coke pushing head 51 is worn after the processing device is used for a long time, it is convenient to replace the worn coke pushing head 51 more conveniently, thereby facilitating the long-term use of the processing device, avoiding the situation where the coke pushing effect of the discharging device is reduced, the coke cannot be effectively pushed, and the equipment is stuck or damaged;

[0031] In this embodiment, the side of the coke pushing head 51 is inclined, and a fixing screw 53 is provided on the top of the coke pushing head 51, and the fixing screw 53 is threadedly connected to the coke pushing head 51. The fixing screw 53 threadedly connected to the coke pushing head 51 can fix and lock the coke pushing head 51 when the coke pushing head 51 is installed at the bottom of the coke pushing plate 1, so as to prevent the coke pushing head 51 from loosening and affecting the coke pushing;

[0032] In this embodiment, a coke pushing rod 22 is provided in the middle of one side of the support plate 2 away from the coke pushing plate 1. The coke pushing rod 22 is engaged and slidably engaged with the coking furnace 6. The coke pushing rod 22 is used to be connected to the driving device so that the driving device pushes the discharging device to perform the coke pushing operation through the coke pushing rod 22.

[0033] In this embodiment, the sliding mechanism 4 includes a sliding rod 41, a sliding sleeve 1 42 and a sliding sleeve 2 43. The sliding rod 41 is fixedly arranged inside the coking furnace 6, the sliding sleeve 1 42 is arranged at the edge of the support plate 2, and the sliding sleeve 2 43 is arranged at the edge of the coke pushing plate 1. The sliding sleeve 1 42 and the sliding sleeve 2 43 are both engaged and slid with the sliding rod 41. Through the engagement and sliding of the sliding sleeve 1 42 and the sliding sleeve 2 43 with the sliding rod 41, it can ensure that the support plate 2 and the coke pushing plate 1 can move stably inside the coking furnace 6.

[0034] The implementation principle of this embodiment is: after the coal inside the coking furnace 6 is coked at high temperature, a driving device such as a hydraulic rod pushes the coke pushing rod 22 to drive the support plate 2 and the coke pushing plate 1 to move in the furnace. At this time, the coke pushing plate 1 together with the coke pushing head 51 at the bottom pushes the coke in the furnace and pushes the coke away from the coking furnace 6. After the coke pushing head 51 is worn out due to long-term use, the fixing screw 53 is rotated, and then the coke pushing head 51 can be removed from the bottom of the coke pushing plate 1. In this way, a new coke pushing head 51 can be replaced to avoid the situation where the coke pushing effect of the discharging device decreases and the coke cannot be effectively pushed when the coke pushing head 51 is worn, causing the equipment to jam or be damaged.

[0035] Embodiment 2:

[0036] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0037] In order to prevent the discharging device from deformation and fracture due to thermal fatigue, the present embodiment provides the following design:

[0038] The cooling mechanism 3 includes a water inlet pipe 31, a water inlet box 32 and a cooling pipe 33. The water inlet pipe 31 is arranged inside the coke pushing rod 22. The water inlet box 32 is arranged at the end of the water inlet pipe 31. The water inlet box 32 is arranged in the middle of the side of the coke pushing plate 1. The side of the water inlet box 32 is provided with a cooling pipe 33. The cooling pipe 33 is located inside the coke pushing plate 1. There are multiple cooling pipes 33 distributed at equal intervals inside the coke pushing plate 1. The multiple cooling pipes 33 facilitate cooling the coke pushing plate 1 from multiple positions.

[0039] As an improvement of the above solution, the middle part of the cooling pipe 33 is connected to the water inlet box 32, and water outlet boxes 34 are provided at the top and bottom ends of the cooling pipe 33. A water outlet pipe 35 is provided in the middle part of the water outlet box 34, and the water outlet box 34 can guide the cooling water to be discharged from the device through the water outlet pipe 35.

[0040] The implementation principle of the second embodiment is: when the discharging device is working in the coking furnace 6, cooling water is sent into the water inlet box 32 through the water inlet pipe 31, and the cooling water entering the water inlet box 32 will evenly enter multiple cooling pipes 33, and finally be discharged from the device through the water outlet box 34 and the water outlet pipe 35. In this way, the pushing plate 1 can be evenly cooled to avoid the breakage or deformation of the pushing plate 1 caused by thermal fatigue due to high temperature.
