Description

Technical Field

[0001] This utility model belongs to the field of coke discharge technology, and specifically relates to a coke discharge system. Background Technology

[0002] Currently, coke is loaded into trucks using an open loading method. When a vehicle enters the coke bin, the operator opens the gate, and the material flows out from the bottom of the hopper and into the truck. During the production process, operators need to be on-site to perform the bin release operation and direct the vehicle forward, which requires additional manpower. At the same time, the falling and collapsing of the material poses a certain danger. Furthermore, after the coke quenching process changed from wet quenching to dry quenching, a large amount of coke powder escapes and some coke spills onto the ground during the open loading process, causing serious air and environmental pollution and harming the health of the workers. Utility Model Content

[0003] To address the problem that existing coke silo discharge processes require on-site operators and consume additional manpower, and to solve the problem of large amounts of coke powder escaping and some coke spilling onto the ground during open loading, causing serious air and environmental pollution, this utility model provides a coke discharge system that reduces manpower and prevents environmental pollution.

[0004] The technical solution adopted by this utility model for a coke discharge system is as follows:

[0005] A coke discharge system includes several coke bins installed on the ground, with silos positioned above each bin. Each silo is connected to the top of the coke bin via a conveying pipe. A movable sliding plate is installed between the conveying pipe and the top of the corresponding coke bin. Each coke bin has a level switch extending into its interior, used to control the corresponding sliding plate.

[0006] Each coke bin is equipped with a flap gate inside the discharge pipe at the bottom, and each coke bin is also equipped with a vertically retractable dust cover around the discharge pipe at the bottom. Additionally, a touch switch is installed on the ground corresponding to the location of each coke bin to control the vertical movement of the corresponding dust cover.

[0007] A further improvement of this utility model is that: each coke bin has a feed inlet connected to the interior at its top, and the end of the conveying pipe away from the silo is aligned with the feed inlet of the corresponding coke bin; wherein, the thickness of the sliding plate is the same as the distance between the end of the conveying pipe away from the silo and the top of the coke bin.

[0008] A further improvement of this utility model is that: a horizontal adjusting rod is provided on the outer wall of each conveying pipe at the end away from the silo, above the sliding plate, and the adjusting rod is connected to the corresponding sliding plate through a vertical connecting rod.

[0009] A further improvement of the present invention is that the dust cover includes a fixed frame connected to the coke bin, and a connecting frame located below the fixed frame for connecting to the hopper of a conveyor truck that transports coke; wherein the fixed frame and the connecting frame are connected by a cover body, and a vertical telescopic rod is also provided between the fixed frame and the connecting frame at a position outside the cover body.

[0010] A further improvement of the above-mentioned technical solution of this utility model is that the shape of the cross-section of the connecting frame is the same as the cross-section of the truck bed of the coke transport vehicle.

[0011] A further improvement of the above-mentioned technical solution of this utility model is that each touch switch is used to control the telescopic rod of the dust cover connected to the corresponding coke bin.

[0012] A further improvement of this utility model is that each coke bin is set on the ground by multiple vertical support legs, and the touch switch is located between the multiple support legs of the corresponding coke bin.

[0013] Due to the adoption of the above technical solution, the technical progress achieved by this utility model includes:

[0014] In this invention, a level switch is installed to detect the coke level in the corresponding coke bin in real time. When the coke level in the coke bin drops to a certain height, it indicates that there is not much coke left. At this time, the level switch can control the slide plate to move. After the slide plate moves, the conveying pipe opens, and the coke in the silo is transported into the coke bin through the opened conveying pipe, thereby replenishing the coke bin in a timely manner. When the level switch detects that the coke level in the coke bin is slightly less than the height of the coke bin, it indicates that the coke bin is full of coke. At this time, the level switch controls the slide plate to move in the opposite direction, and the slide plate closes the conveying pipe, thereby preventing the coke in the silo from continuing to be transported into the coke bin and causing damage to the coke bin.

[0015] Meanwhile, the flap gate in this invention can control the opening and closing of the discharge pipe, thereby remotely controlling whether the coke hopper discharges material through remote control of the flap gate, eliminating the need for manual on-site discharge operations.

[0016] Meanwhile, since the fixing rod and the connecting rod are detachably connected in this utility model, it is convenient to disassemble this utility model into two parts when it is not in use, thereby reducing the space occupied by this utility model.

[0017] Furthermore, in this invention, when the conveyor vehicle moves to the bottom of the coke bin, it presses against the touch switch. At this time, the touch switch closes, and the closed touch switch controls the dust cover to extend downward until the connecting frame of the dust cover is in contact with the bucket of the conveyor vehicle. Thus, the space between the discharge pipe and the bucket of the conveyor vehicle is sealed by the dust cover, preventing coke powder or coke from being scattered into the atmosphere through the space between the discharge pipe and the bucket of the conveyor vehicle during the discharge process of the coke bin, which would cause environmental pollution.

[0025] 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 specific embodiments and accompanying drawings. In the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concept of this utility model.

[0026] First reference Figure 1 ,according to Figure 1 As can be seen, this utility model includes several coke bins 1 set on the ground. The number of coke bins 1 can be one or more. Each coke bin 1 is supported on the ground by a support leg 12. At the same time, a silo 2 is set above all coke bins 1. In this utility model, the top of each coke bin 1 is connected to the bottom of the silo 2 through a conveying pipe 3. In this utility model, in order to facilitate the conveying of coke into the silo 2, a conveyor belt can be connected to the top of the silo 2, so as to facilitate the conveying of coke into the silo 2 by the conveyor belt.

[0027] In this utility model, the material conveying pipe 3 and the coke bin 1 are specifically connected by referring to... Figure 2 and Figure 3 It is known that each coke bin 1 has a feed inlet at the top that is connected to the internal storage space of the coke bin 1, and the end of the conveying pipe 3 corresponding to each coke bin 1 that is away from the silo 2 is aligned with its own feed inlet. The slide plate 4 is located between the silo 2 and the conveying pipe 3, and a horizontal adjusting rod 31 is fixedly connected to the outer wall of the end of the conveying pipe 3 that is away from the silo 2 above the slide plate 4. The adjusting rod 31 can be a rod body such as an electric telescopic rod 55 or a hydraulic telescopic rod 55 commonly used in the prior art, and the adjusting rod 31 is connected to the corresponding slide plate 4 through a vertical connecting rod 32.

[0028] In this invention, to facilitate the simultaneous sealing of the feed inlet of the coke bin 1 and the end of the conveying pipe 3 away from the silo 2 by the sliding plate 4, the thickness of the sliding plate 4 is the same as the distance between the end of the conveying pipe 3 away from the silo 2 and the feed pipe of the coke bin 1. At the same time, the large cross-section of the sliding plate 4 is larger than the cross-section of the feed inlet and the cross-section of the end of the conveying pipe 3 away from the silo 2, thereby facilitating the simultaneous sealing of the feed inlet of the coke bin 1 and the end of the conveying pipe 3 away from the silo 2 by the sliding plate 4.

[0029] Continue to refer Figure 2 and Figure 3 In this invention, to facilitate control of the slide plate 4, a level switch 11 extending into the interior of each coke bin 1 is fixedly installed on the top. This level switch 11 can be a commonly used tuning fork level switch 11 or a radio frequency level switch 11. Each level switch 11 can control the adjusting rod 31 on the corresponding coke bin 1. When the level switch 11 detects that the coke level in the coke bin 1 is slightly higher than the bottom of the coke bin 1, the level switch 11 controls the adjusting rod 31 to extend. The extended adjusting rod 31 drives the slide plate 4 to move. At this time, the feed inlet and feed outlet of the coke bin 1 on the slide plate 4 are... The end of the conveying pipe 3 furthest from the silo 2 opens simultaneously, allowing coke in the silo 2 to move into the coke bin 1 via the conveying pipe 3, thus replenishing the coke bin 1. When the level switch 11 detects that the coke level in the coke bin 1 is slightly lower than the top of the coke bin 1, the level switch 11 controls the adjusting rod 31 to retract. The extended adjusting rod 31 drives the sliding plate 4 to move in the opposite direction. At this time, the inlet of the sliding plate 4 into the coke bin 1 and the end of the conveying pipe 3 furthest from the silo 2 are simultaneously closed, thus preventing coke in the silo 2 from continuing to move into the coke bin 1 via the conveying pipe 3, thereby protecting the coke bin 1. The wiring method between the level switch 11 and the adjusting rod 31 can be wired by technicians according to the actual site conditions, and there is no technical difficulty involved, so it will not be described in detail here.

[0030] Meanwhile, in order to facilitate observation of the position of the skateboard 4, a camera (not shown in the figure) for taking pictures of the skateboard 4 can be installed on the top of each coking chamber 1 in this utility model. The real-time image of the camera can be transmitted to the control room, so as to facilitate real-time observation of the position of the skateboard 4.

[0031] Continue to refer Figure 3 It can be seen that in this utility model, each coke bin 1 is equipped with a vertically retractable dust cover 5 at the bottom of the discharge pipe. The dust cover 5 is specifically designed with reference to... Figure 4 It can be seen that the dust cover 5 includes a fixing frame 52 that is fixedly connected to the bottom of the coke bin 1 and sleeved on the discharge pipe. The fixing frame 52 can be fixedly connected to the bottom of the coke bin 1 by welding or bolts. (Continue to refer to...) Figure 4 A connecting frame 53 is provided below the fixing frame 52. The cross-sectional shape of the connecting frame 53 is the same as the cross-sectional shape of the conveyor hopper of the coke transport vehicle. The fixing frame 52 and the connecting frame 53 are connected by a cover 54, which can be made of flexible materials such as dustproof cloth commonly used in the prior art. (Continue to refer to...) Figure 4 It is known that a vertical telescopic rod 55 is also provided on the outside of the cover 54 between the fixed frame 52 and the connecting frame 53. The telescopic rod 55 can be a commonly used electric telescopic rod or hydraulic rod in the prior art. In order for the connecting frame 53 to move horizontally up and down, at least two telescopic rods 55 should be arranged, located on the front and rear sides or left and right sides of the cover 54 respectively. At the same time, the number of telescopic rods 55 can also be an even number of two or more, evenly distributed on the front, rear, left and right sides of the cover 54.

[0032] Continue to refer Figure 1 On the ground, corresponding to each coke bin 1 and located at the position of multiple support legs 12, there is a touch switch 51 for controlling the dust cover 5 on the corresponding coke bin 1. When the transport vehicle needs to transport coke, the transport vehicle moves between the multiple support legs 12, and at the same time, the wheels of the transport vehicle press on the touch switch 51. At this time, the truck bed of the transport vehicle is aligned with the connecting frame 53 of the dust cover 5 and the touch switch 51 is closed. The closed touch switch 51 controls the extension rod 55 to extend. The extended extension rod 55 drives the connecting frame 53 to move downward until the connecting frame 53 contacts the truck bed of the transport vehicle. At this time, the dust cover 5 seals the space between the discharge pipe and the truck bed of the transport vehicle, preventing coke powder or coke from being scattered into the atmosphere through the space between the discharge pipe and the truck bed of the coke bin 1 during the discharge process, thus preventing environmental pollution.

[0033] To further facilitate the positioning of the transport vehicle, four pressure switches 51 can be installed under each coke bin 1, corresponding to the four wheels of the transport vehicle, one in front, one behind, one in the left, and one in the right. The four pressure switches 51 are connected in series. Only when the four wheels of the transport vehicle are respectively located on the corresponding pressure switches 51 can the four pressure switches 51 be closed simultaneously to control the dust cover 5 to extend downward. When the transport vehicle is located under the coke bin 1 but the dust cover 5 does not move, it means that the truck bed of the transport vehicle is not aligned with the connecting frame 53 and the position of the transport vehicle needs to be readjusted.

[0034] Furthermore, a negative pressure dust collection system or a water mist system (not shown in the figure) is provided on the inner wall of the fixing frame 52 to reduce the coke dust inside the dust cover 5 and prevent the coke dust inside the dust cover 5 from being dispersed into the air after the dust cover 5 is opened.

[0035] In this utility model, the wiring method between the pressure switch 51 and the telescopic rod 55 can be carried out by technicians according to the actual site conditions, and there is no technical difficulty. It will not be described in detail here.

[0036] In order to facilitate the control of the opening and closing of the discharge pipe of the coke bin 1, each coke bin 1 is equipped with a flap gate (not shown in the figure) in the discharge pipe. The flap gate can be remotely controlled by a control switch located in the control room.

[0037] The working principle of the coke discharge system in this embodiment is as follows: Figure 1 As shown, when using this utility model, the conveyor car is driven to the bottom of the coke bin 1 and the bucket is aligned with the connecting frame 53 of the dust cover 5. At this time, the touch switch 51 is closed, and the dust cover 5 extends downward until it contacts the bucket of the conveyor car. Then, the flap gate is opened remotely by the control switch, and the coke in the coke bin 1 enters the bucket through the discharge pipe.

[0038] Meanwhile, in this utility model, when the level switch 11 detects that the coke height in the coke bin 1 has dropped to a certain level (e.g., the coke height is one meter higher than the bottom of the coke bin 1), it indicates that there is not much coke left in the coke bin 1. At this time, the level switch 11 controls the control rod 31 to extend, and the extended control rod 31 drives the slide plate 4 to move. At this time, the feed inlet of the coke bin 1 and the end of the conveying pipe 3 away from the silo 2 of the slide plate 4 open simultaneously, so that the coke in the silo 2 moves into the coke bin 1 through the conveying pipe 3, achieving the purpose of replenishing the coke in the coke bin 1. When the level switch 11 detects that the coke height in the coke bin 1 is slightly lower than the top of the coke bin 1 (e.g., the coke height is one meter lower than the top of the coke bin 1), the level switch 11 controls the control rod 31 to retract, and the extended control rod 31 drives the slide plate 4 to move in the opposite direction. At this time, the feed inlet of the coke bin 1 and the end of the conveying pipe 3 away from the silo 2 of the slide plate 4 close simultaneously, thereby preventing the coke in the silo 2 from continuing to move into the coke bin 1 through the conveying pipe 3, achieving the purpose of protecting the coke bin 1.

[0039] In the above embodiments, this utility model provides a coke discharge system. The system utilizes a flap gate to control the opening and closing of the discharge pipe, allowing remote control of whether the coke bin discharges material without requiring manual on-site operation. Furthermore, when the conveyor vehicle moves to the bottom of the coke bin, it presses against a touch switch, closing it. This closed switch controls the dust cover to extend downwards until its connecting frame is flush with the conveyor vehicle's hopper. This effectively seals the space between the discharge pipe and the conveyor vehicle's hopper, preventing coke powder or coke from scattering into the atmosphere and causing environmental pollution during discharge.

[0040] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
