Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-6 , the present invention provides a technical solution: an automatic coke discharging program control system, including a carbonization part, a coke discharging part, a control part, and a coke discharging and transporting part;

[0023] The carbonization part includes a carbonization furnace 1. The carbonization furnace 1 is divided into a single carbonization furnace 1 or multiple groups of carbonization furnaces 1, and the carbonization furnace 1 is used for carbonization. The coke discharging part includes a coke discharging bin 2. There are two groups of coke discharging bins 2, and the two groups of coke discharging bins 2 are distributed up and down. The coke discharging bin 2 located in the upper part receives the semi-coke after carbonization in the carbonization furnace 1 for coke discharging. The control part includes a controller 3 and a coke discharging valve 4. The bottom of each coke discharging bin 2 is connected with a coke discharging pipe 5, and the coke discharging valve 4 is installed outside the coke discharging pipe 5. The controller 3 is used to control and adjust the opening and closing of the coke discharging valve 4. The control part also includes a detection component, which is used to detect the material level in the coke discharging bin 2 and control the opening and closing of the coke discharging valve 4 through the controller 3 with a data signal. The coke discharging and transporting part includes a coke discharging belt 6, a coke box 7, and a rubber scraping mechanism. The coke discharged from the lower coke discharging bin 2 is transported to the coke box 7 through the coke discharging belt 6. The rubber scraping mechanism includes a rubber scraping plate 8 installed between the coke box 7 and the coke discharging belt 6.

[0024] The outside of the carbonization furnace 1 is connected with a mounting bracket 9 installed on the wall, and the outside of the coke discharging bin 2 is connected with a coke bin support 21 connected to the cavity. The upper and lower two coke discharging valves 4 are set to be interlocked and are not allowed to be opened simultaneously.

[0025] As shown in the attached Figure 4 and the attached Figure 5As shown in the figure, for the material level detection of the coke discharging bin 2, the detection component includes a rotating disk 22 sleeved on the top of the coke discharging bin 2. A connecting bracket 23 is connected to the rotating disk 22. The bottoms of a plurality of connecting brackets 23 are connected to a material level detection disk 24, and the material level detection disks 24 are distributed inside the coke discharging bin 2. The coke bin bracket 21 is connected with a transmission member. The bottom of the transmission member is connected to the roller shaft of the coke discharging belt 6, and the top of the transmission member drives the outside of the rotating disk 22 to rotate. The transmission member includes a first transmission belt 25. The bottom of the first transmission belt 25 is connected to the roller shaft of the coke discharging belt 6. A roller 26 is connected between the coke discharging bin 2 and the coke bin bracket 21, and the top of the first transmission belt 25 is connected to the lower roller 26. The upper roller 26 and the lower roller 26 are connected by a second transmission belt 27. One end of the roller 26 is connected with a helical gear 28. A toothed ring 29 meshing with the helical gear 28 is installed outside the rotating disk 22. A multi-point contact sensing sheet is installed on the material level detection disk 24, and there is a hole in the middle of the material level detection disk 24.

[0026] Through the synchronous transportation of the coke discharging belt 6, the roller shafts 26 of a plurality of coke discharging belts 6 are in a rolling state. Because under the action of the first transmission belt 25, the lower roller shaft 26 is driven to rotate. Through the transmission of the second transmission belt 27, the upper roller shaft 26 also starts to rotate, and then the two helical gears 28 mesh to drive the toothed disk 29, so that the rotating disk 22 starts to rotate at the positions of the upper coke discharging bin 2 and the lower coke discharging bin 2. Since the rotating disk 22 is connected to the material level detection disk 24 through the connecting bracket 23, the material level detection disk 24 and the coke discharging bin 2 are in full contact. During the rotation process, on the one hand, it is convenient for the coke to be discharged smoothly and avoid coke sticking. On the other hand, it is beneficial for the contact sensing sheet on the material level detection disk 24 to be in full contact with the material level in the coke discharging bin 2, so as to facilitate the detection of the material level in the coke discharging bin 2.

[0027] As Figure 1 As shown in the figure, taking four carbonization furnaces as an example, two series-connected coke discharging bins 2 are arranged under each carbonization furnace 1. Independent coke discharging valves 4 are arranged at the coke discharging ports of each coke discharging bin 2, namely the upper coke discharging valve 4 and the lower coke discharging valve 4. The controller 3 controls the opening and closing of the upper coke discharging valve 4 and the lower coke discharging valve 4 to control the coke in the carbonization furnace 1 to flow into the coke discharging and transferring part, realizing coke discharging without stopping the vehicle, and not stopping the vehicle due to the delay or blockage of coke discharging in the carbonization furnace 1. At the same time, the coke discharging efficiency of the system is improved.

[0028] It should be noted that the aforementioned carbonization furnace 1 has a double-carbonization chamber structure, that is, there are two carbonization chambers in the furnace. The double-chamber carbonization furnace 1 can not only improve the carbonization efficiency, but also form activated carbon or semi-coke with different parameters at the same time. In addition, the double-chamber carbonization furnace 1 can also prevent air from entering the coke bin where the coke is extinguished and cause safety accidents such as flash explosions. The controller 3 is a PLC or a single-chip microcomputer.

[0029] The following is an example of the control of the coke discharging valve 4 in the upper part and the coke discharging valve 4 in the lower part by the controller in this embodiment:

[0030] As Figure 6 shown, the coke discharging bin A1 represents the upper coke discharging bin 2 mentioned above, the coke discharging bin A2 represents the lower coke discharging bin 2 mentioned above, the coke discharging valve A1 represents the upper coke discharging valve 4 mentioned above, the coke discharging valve A2 represents the lower coke discharging valve 4, the coke discharging belt, and the carbonization furnaces A, B, C, and D represent four different carbonization furnaces 1.

[0031] 1) Single furnace coke discharging operation: The semi-coke produced by the carbonization furnace 1 is discharged into the coke discharging bin 2 through the coke discharging valve or the pusher. When the material level in the coke discharging bin 2 reaches more than 80%, confirm that the coke discharging valve 4 is closed, and the controller 3 controls the coke discharging valve 4 to open, and discharges the semi-coke in the upper coke discharging bin 2 into the lower coke discharging bin 2. After discharging, close the upper coke discharging valve 4, and the controller 3 controls the lower coke discharging valve 4 to open, and discharges the semi-coke in the lower coke discharging bin 2 into the coke discharging belt 6 and sends it to the coke box 7 outside.

By analogy, the B, C, and D systems are set in the same way.

[0034] ② The lower coke discharging bin 2 of each set of systems is not allowed to be emptied.
