Description

Technical Field

[0001] The utility model relates to the technical field of coke silos, in particular to a device for preventing coke from falling and breaking in a coke silo. Background Art

[0002] When the finished coke transported by the belt conveyor through the dry quenching device of the coking plant is stored in a silo as a coke storage or loading buffer facility, the coke silo is usually designed without a coke anti-falling and breakage device. The coke on the finished coke transport belt conveyor at the top of the silo naturally falls directly from the chute outlets on both sides of the unloading car at the top of the silo or the funnel outlet at the head of the belt conveyor to the bottom of the silo, and then slowly accumulates upward until the coke is loaded close to the top of the silo. The secondary crushing and dust caused by the fall can be slowed down due to the reduction in the drop height. Especially when the coke is first stored in the silo, due to the large drop height of the coke in the silo and the lack of an anti-falling and breakage device, the coke will be secondary crushed in the silo and produce a large amount of coke powder dust, resulting in an increase in coke powder in the finished coke.

[0003] When in use, the existing coke prevention device usually uses multi-stage buffer components connected in series end to end to extend the distance, so that the coke can weaken the force over a long distance after transmission to achieve the effect of preventing it from falling. For example, application number CN202123389375.6 provides a coke prevention device for coke silos, which belongs to the field of coke storage and is used to solve the problem that there is no coke prevention device for falling and breaking in the coke silo, which leads to an increase in coke powder in the coke stored therein; however, in the above technology, the buffer structure is directly arranged inside the cabin for stacking and placement. Due to the complex structure, it causes more difficulties for the staff to install and set up, and due to the excessive number of components, it reduces the work efficiency and increases the cost of use.

[0024] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] The present invention is further described in detail below with reference to the embodiments:

[0026] like Figure 1-5 As shown, the utility model provides a device for preventing coke from falling and breaking for a coke silo, comprising a coke silo 1, a collecting bottom hopper 2, a sensor 4, a conveyor belt 6 and a discharge barrel lifting device 8. A telescopic guide discharge barrel 3 is provided inside the coke silo 1, and a discharge funnel 5 is fixedly connected to the top of the telescopic guide discharge barrel 3. A fixing groove for installing the discharge funnel 5 is opened on the top of the coke silo 1.

[0027] The inner wall of the discharge hopper 5 is rotatably connected to a buffer plate group 16. The buffer plate group 16 includes a first oblique buffer plate 18 and a second oblique buffer plate 19 whose sides overlap each other. The bottom surfaces of the first oblique buffer plate 18 and the second oblique buffer plate 19 are fixedly connected to a buffer spring 17, and the tail end of the buffer spring 17 is fixedly connected to the inner wall of the discharge hopper 5. When the coke in the conveyor belt 6 is transported to the discharge hopper 5, when the coke falls on the first oblique buffer plate 18 and the second oblique buffer plate 19, it will impact both and compress the buffer spring 17. The deformation of the buffer spring 17 absorbs the impact of the coke, thereby providing a buffering effect on it. In addition, the buffer plate group 16 is distributed in multiple stages in the discharge hopper 5, which can form a multi-stage buffering effect, thereby ensuring the subsequent transportation of coke.

[0028] The outer wall of the bottom end of the telescopic guide discharge barrel 3 is fixedly connected to a mounting bottom ring 11, and the top of the mounting bottom ring 11 is fixedly connected to a traction line 12. The end of the traction line 12 away from the mounting bottom ring 11 is movably connected to the outer wall of the take-up roller of the discharge barrel lifting device 8.

[0029] The telescopic guide discharge cylinder 3 includes a grading bottom cylinder 9 and a grading built-in cylinder 10. The bottom end of the grading bottom cylinder 9 is fixedly connected to the inner wall of the mounting bottom ring 11, and the outer wall of the grading built-in cylinder 10 is slidably connected to the inner wall of the grading bottom cylinder 9. The inner wall of the grading bottom cylinder 9 near the bottom end is provided with an inner ring for receiving the bottom end of the grading built-in cylinder 10. When the grading bottom cylinder 9 moves up to the same height as the grading built-in cylinder 10, the inner ring can be used to lift the grading built-in cylinder 10 upward. Similarly, the inner wall of the grading built-in cylinder 10 is also provided with a similarly adapted inner ring, which facilitates the overall lifting and retraction of the telescopic guide discharge cylinder 3.

[0030] The side of the sensor 4 close to the top is fixedly connected to the outer wall of the grading bottom cylinder 9 through the mounting column 13. The sensor 4 can be a radar level meter or an ultrasonic level meter.

[0031] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the conveyor belt 6 is located on one side of the discharge funnel 5, and the bottom surface of the conveyor belt 6 is fixedly connected to the top of the coke silo 1 through a reinforcement frame.

[0032] A guide hole for the movement of the traction line 12 is provided on the top of the coke silo 1 .

[0033] The top of the charcoal silo 1 is fixedly connected to a support frame 7 , a mounting groove 14 is provided on the top of the support frame 7 , the inner wall of the mounting groove 14 is rotatably connected to a fixed pulley 15 , and the outer wall of the fixed pulley 15 overlaps the outer wall of the traction line 12 .

[0034] There are two pulling lines 12 , which are symmetrically distributed on both sides of the telescopic guide discharge barrel 3 .

[0035] The bottom end of the telescopic guide discharge barrel 3 overlaps the inner wall of the collecting bottom hopper 2.

[0036] The following is a detailed description of the working principle of the coke falling and breaking prevention device for coke silo.

[0037] like Figure 1-5 As shown, when in use, the coke is conveyed to the discharge funnel 5 through the conveyor belt 6, and the coke in the discharge funnel 5 is gradually collected into the telescopic guide discharge barrel 3 through its bottom discharge port, and guided to the collecting bottom bucket 2 through the telescopic guide discharge barrel 3. At this time, the bottom end of the telescopic guide discharge barrel 3 and the inner wall of the collecting bottom bucket 2 are in an overlapping state. As the coke continues to fall, when the inner wall of the telescopic guide discharge barrel 3 is filled, the bottom end of the telescopic guide discharge barrel 3 will move up a certain distance under the extrusion of the coke, and at this time the coke in the collecting bottom bucket 2 will also form a conical distribution.

[0038] At this time, after the sensor 4 detects that the height of the coke in the collecting bottom hopper 2 has reached the rated range, it will feed back the signal to the controller of the discharge barrel lifting device 8. At this time, the discharge barrel lifting device 8 starts to reel in the traction line 12, and the traction line 12 will pull the installation bottom ring 11 upward. During the upward movement, the installation bottom ring 11 will drive the grading bottom barrel 9 to gradually move upward. When the grading bottom barrel 9 moves upward, the coke inside it will be discharged, and the coke on the upper part of the telescopic guide discharge barrel 3 will move downward as a whole, thereby greatly reducing the drop formed during the coke discharge process.

[0039] As the grading bottom barrel 9 gradually moves upward, the overall length of the telescopic guide lower barrel 3 gradually decreases until the coke in the coke silo 1 reaches a suitable stacking height.

[0040] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
