Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of coking branches, and particularly relates to a double-branch chute and dry quenching device. BACKGROUND

[0002] In the field of dry quenching production, efficient and stable material transfer plays a key role in the smooth operation of the entire production process. Among them, the double-branch chute, as the core mechanism for controlling material transfer, plays an important role in the dry quenching production line. Generally, the double-branch chute is installed on the upper part of the belt conveying system and is closely linked with the belt unit, bearing the heavy responsibility of accurately diverting the quenched coke to different belts and then conveying it to the subsequent processing or storage link.

[0003] At present, the double-branch chutes widely used in dry quenching production lines mostly adopt a flip plate structure. This flip plate type double-branch chute controls the opening and closing state of the two chute pipes through a flip plate. However, this structure has obvious defects. On the one hand, it cannot simultaneously open or close the two chute pipes, greatly limiting its flexibility in maintenance work. In actual production, when a chute pipe needs to be maintained, it is extremely complex due to the inability to simultaneously close both pipes, not only prolonging the maintenance time, but also increasing the safety hazards.

[0004] On the other hand, the flip plate type double-branch chute places the rotating shaft inside the chute pipe, which brings many problems in actual operation. The coke generates a large resistance during falling, and the rotating shaft needs to overcome this resistance to realize the rotation of the flip plate, which not only increases the energy consumption of the equipment, but also easily causes the flip plate to move unsmoothly. More seriously, in the long-term production process, the flip plate is easily stuck by the falling coke, causing the chute pipe to be unable to be completely sealed. Once this happens, not only will it affect the normal conveying of coke and reduce production efficiency, but it will also cause a large amount of dust to overflow, causing serious pollution to the production environment, and also increasing the maintenance cost and difficulty of the equipment. CONTENT OF THE UTILITY MODEL

[0015] Optionally, material blocking steps are arranged on the inner wall of the first branch chute and the second branch chute, which contact the coke, and the material blocking steps are in a staggered structure, and are used to change the falling trajectory and speed of the coke, so that the coke collides and rubs with each other during the falling process.

[0031] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0032] The first aspect of the embodiments of the present application provides a double branch chute, and the second aspect of the embodiments of the present application provides a dry quenching device.

[0033] The double branch chute is applied to the dry quenching device.

[0034] Specifically, in actual application, the dry quenching device is used for cooling the hot coke, and after the coke is cooled to a suitable temperature, it will be discharged from the sealing valve of the dry quenching device. At this time, the double bifurcated chute closely connected with the sealing valve begins to play a role, which is used to stably receive the cooled coke discharged from the sealing valve, and ensures that the coke can smoothly enter the subsequent conveying link, avoiding the problems of spilling, piling and other problems affecting the continuity of production during the discharging process. It can be understood that in the conveying link of the coke, the cooled coke usually needs to be conveyed to different storage areas or sent to different processing procedures to meet the diversified production needs in the subsequent production. The double bifurcated chute receives the coke and accurately divides the flow according to the production instruction, flexibly controls the opening and closing state of the two chute pipelines, so as to realize the directional conveying of the coke and ensure that each production link can timely and accurately obtain the required amount of coke.

[0035] Referring to Figures 1 to 4 As shown in the figure, the double bifurcated chute provided in the embodiment of the present application comprises: a main chute 1 connected with the sealing valve of the dry quenching device, the main chute 1 being used for receiving the cooled coke; a first bifurcated chute 2 and a second bifurcated chute 3, the first bifurcated chute 2 and the second bifurcated chute 3 being arranged on the downstream side of the main chute 1 along the coke conveying direction, the first bifurcated chute 2 and the second bifurcated chute 3 being connected with the main chute 1 through a three-way chute 4, and the first bifurcated chute 2 and the second bifurcated chute 3 being used for dividing the flow of the coke; wherein, the first bifurcated chute 2 and the second bifurcated chute 3 are both provided with a gate 5 on the upstream side of the coke discharge port along the coke conveying direction, the gate 5 being connected with a control device 6, and the control device 6 being used for controlling the opening and closing of the gate 5.

[0036] In this embodiment, the first bifurcated chute 2 and the second bifurcated chute 3 are connected with the main chute 1 through the three-way chute 4, and the cooled coke can be accurately divided into different paths according to the actual production needs. At the same time, the first bifurcated chute 2 and the second bifurcated chute 3 are both provided with the gate 5 connected with the control device 6 on the upstream side of the coke discharge port along the coke conveying direction, so that the gate 5 of the first bifurcated chute 2 and the second bifurcated chute 3 can be independently controlled to open and close. Compared with the traditional structure that cannot control the opening and closing of the two chute pipelines at the same time, the maintenance time is greatly shortened, the maintenance efficiency is improved, and the influence on the overall production is reduced. At the same time, the gate 5 is of a flat plate structure and is located on the upstream side of the coke discharge port. Compared with the traditional flip plate structure in which the rotating shaft is arranged in the chute pipeline, the situation that the gate 5 is stuck by the coke is avoided, so that the gate 5 is not disturbed by the direct impact and resistance of the falling coke, and can be more stably and smoothly opened and closed, ensuring the long-term stable operation of the equipment.

[0037] The main chute 1 is the starting key part of the whole double bifurcated chute, and one end is tightly connected with the sealing valve of the coke dry quenching device. In the coke dry quenching process, the hot coke is discharged from the sealing valve of the coke dry quenching device after being cooled, and the main chute 1 can play a role in receiving these cooled coke, and prepare for subsequent split conveying. That is, the main chute 1 is the total inlet channel of the whole double bifurcated chute, which can ensure that the cooled coke can smoothly enter the double bifurcated chute.

[0038] Specifically, the end of the main chute 1 close to the sealing valve is provided with a connecting flange, and the main chute 1 is tightly connected with the sealing valve of the coke dry quenching device through the connecting flange and bolts.

[0039] The first bifurcated chute 2 and the second bifurcated chute 3 are core components for realizing coke split conveying, and are located on the downstream side of the main chute 1 along the conveying direction of the coke. The first bifurcated chute 2 and the second bifurcated chute 3 are connected with the main chute 1 through the three-way chute 4, so that the coke conveyed from the main chute 1 can be distributed to different paths according to production needs. For example, in actual production, the first bifurcated chute 2 can convey the coke to a storage area, and the second bifurcated chute 3 can convey the coke to a production line for further processing.

[0040] The three-way chute 4 is a key connecting hub for realizing the split conveying function, and its shape is similar to a "three-way" pipeline, realizing the communication of one main channel (the main chute 1) and two branch channels (the first bifurcated chute 2 and the second bifurcated chute 3), and ensuring that the coke can smoothly flow from the main chute 1 to the first bifurcated chute 2 and the second bifurcated chute 3.

[0041] Specifically, the connecting flanges are also arranged at the connection between the main chute 1 and the three-way chute 4, and the connection between the three-way chute 4 and the first bifurcated chute 2 and the second bifurcated chute 3. When assembling the double bifurcated chute, the connecting flanges at the corresponding positions are aligned, and the double bifurcated chute can be quickly spliced through the connection of bolts and nuts.

[0042] In the first bifurcated chute 2 and the second bifurcated chute 3, a gate 5 is installed at the upstream position of the coke discharge port along the coke conveying direction. These gates 5 are like valves controlling water flow, controlling the flow of coke in the bifurcated chute. When the gate 5 is opened, the coke can be smoothly conveyed through the bifurcated chute to the designated position; when the gate 5 is closed, the coke cannot pass through, thereby realizing the control of the coke conveying in the bifurcated chute.

[0043] Specifically, gate 5 has a flat plate structure, and its movement path is perpendicular to the coke conveying direction. In practical applications, when driving gate 5 to move, because its movement path is perpendicular to the coke conveying direction, gate 5 is not affected by lateral forces generated by the coke flow during opening or closing. This ensures the stability and smoothness of gate 5's operation, greatly reduces the risk of jamming due to external obstruction, guarantees the stable operation of the double-forked chute, avoids production interruptions caused by equipment failure, and effectively improves the continuity and efficiency of dry quenching production. Furthermore, the vertical movement allows the flat plate gate 5 to achieve a tight fit with the inner wall of the forked chute when closed. Regardless of the coke flow rate or velocity, it effectively prevents the leakage of coke and dust, forming a good sealing environment, thereby maintaining a clean production environment and reducing the harm of dust to equipment and operator health.

[0044] Each gate 5 is connected to a corresponding control device 6, enabling operators to individually and precisely control the gates 5 in different branch chutes.

[0045] Specifically, the control device 6 can be a hydraulic push rod, an electric push rod, or an actuation push rod, etc. When the control device 6 is a hydraulic push rod, the linear movement of the push rod is achieved through the pressure transmission of hydraulic oil in the closed system. In practical applications, when the operator issues a control command, the oil pump in the hydraulic system delivers hydraulic oil to the cylinder of the hydraulic push rod, pushing the piston to move, which in turn drives the connected flat gate 5 to move perpendicular to the coke conveying direction.

[0046] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 and Figure 4 As shown, both the first bifurcation chute 2 and the second bifurcation chute 3 are provided with regulating troughs 7 on the upstream side of the coke discharge port along the coke conveying direction. The gate 5 is movably disposed in the regulating trough 7. The moving path of the gate 5 includes a first limit position and a second limit position. When the gate 5 moves to the first limit position, the gate 5 cuts off the coke flow in the regulating trough 7. When the gate 5 moves to the second limit position, the gate 5 releases the coke flow in the regulating trough 7.

[0047] In this embodiment, the gate 5 can move to different positions within the regulating trough 7. When it is in different extreme positions, it can completely cut off or completely release the coke flow in the first branch chute 2 and the second branch chute 3. Combined with the situation where the gate 5 is between the two extreme positions, it can achieve flexible distribution and precise adjustment of the coke flow in the two branch chutes, meet the specific needs of different production links or different processing units for coke quantity, and improve the adaptability and controllability of the entire production process.

[0048] In this embodiment, both the first bifurcation chute 2 and the second bifurcation chute 3 are equipped with regulating troughs 7 on the upstream side of the coke discharge port in the coke conveying direction. In this embodiment, the regulating trough 7 is an independent control area outside the coke discharge port, providing dedicated space for the movement of the gate 5, allowing the gate 5 to move freely and stably within it, thereby achieving effective control of the coke flow within the bifurcation chute.

[0049] The gate 5 is movably installed within the regulating groove 7. In other words, the gate 5 is not fixed but can be moved within the regulating groove 7 according to actual production needs. Specifically, the gate 5 can move along a preset path on the regulating groove 7, which acts as a "track".

[0050] Specifically, a through slot for the clearance gate 5 is provided on one side wall of the regulating trough 7, ensuring that the gate 5 can smoothly move back and forth between the first and second extreme positions within the regulating trough 7. When the gate 5 moves to the first extreme position under the drive of the control device 6, the gate 5 enters the regulating trough 7 through the through slot, completely cutting off the coke flow within the regulating trough 7. When the gate 5 moves to the second extreme position under the drive of the control device 6, the gate 5 exits from the regulating trough 7 through the through slot, completely releasing the obstruction to the coke flow within the regulating trough 7.

[0051] In some possible implementations disclosed in this application, see [link to relevant documentation]. Figure 2 and Figure 4 As shown, at least two adjusting plates 8 are rotatably provided on the inner wall of the adjusting groove 7. The at least two adjusting plates 8 are located on the side of the gate 5 away from the coke discharge port and extend along the moving direction of the gate 5. When the gate 5 moves to the first limit position, the free ends of the at least two adjusting plates 8 cooperate with the gate 5 to seal the gap between the gate 5 and the adjusting groove 7.

[0052] In this embodiment, the tight fit between the regulating plate 8 and the gate 5 enables more precise flow control when the gate 5 cuts off the coke flow. Because the gap is effectively sealed, the coke flow is cut off more thoroughly, providing more accurate control when precise control of the coke delivery rate is required. This helps improve the accuracy of coke flow regulation during dry quenching production, meeting the needs of different production processes. Simultaneously, the good seal significantly reduces the escape of coke dust from the gap between the gate 5 and the regulating channel 7, improving the working environment, reducing the health hazards of dust to operators, and minimizing dust pollution to the surrounding environment.

[0053] In practical applications, the double-forked chute is arranged vertically, and the position and movement characteristics of the regulating plate 8 are significantly affected by gravity. Since the regulating plate 8 is rotatably mounted on the inner wall of the regulating chute 7 and located on the side of the gate 5 away from the coke discharge port, it naturally droops under the continuous action of gravity.

[0054] Specifically, when the gate 5 reaches the first limit position, the adjusting plate 8 precisely rests on the gate 5 under the action of gravity. At this time, gravity becomes a key booster for the close contact between the adjusting plate 8 and the gate 5, so that the contact between the adjusting plate 8 and the gate 5 is more close, effectively eliminating the gap that may exist between the gate 5 and the adjusting groove 7.

[0055] Among them, the adjusting plate 8 is provided with two, the two adjusting plates 8 are oppositely arranged and extend along the moving direction of the gate 5 to fill the gap that may exist between the gate 5 and the adjusting groove 7.

[0056] Specifically, the connecting end of the two adjusting plates 8 is rotationally connected with the inner wall of the adjusting groove 7 through a rotating shaft. This connection mode gives the adjusting plate 8 the characteristic of flexible rotation. When the double bifurcated chute is in the actual running state, the free end of the two adjusting plates 8 presents a unique posture in the opposite direction under the action of its own gravity, which precisely rests on the gate 5. Therefore, when the gate 5 is in the first limit position, the adjusting plate 8 can closely contact the gate 5, effectively fill the gap between the gate 5 and the adjusting groove 7, and further realize effective cutting and sealing of the coke flow in the adjusting groove 7, thereby ensuring the stable operation and efficient work of the entire double bifurcated chute system.

[0057] In some possible implementation embodiments disclosed in the present application, referring to Figure 2 As shown in the figure, the free end of the gate 5 is provided with a limiting block 9, which abuts against the inner wall of the adjusting groove 7 when the gate 5 moves to the second limit position.

[0058] In this embodiment, when the gate 5 moves to the second limit position, the limiting block 9 abuts against the inner wall of the adjusting groove 7, which can accurately define the position of the gate 5, so that the gate 5 will not completely exit from the adjusting groove 7, and eliminate the hidden danger of equipment failure caused by excessive movement of the gate 5.

[0059] Among them, when the operator controls the movement of the gate 5 through the control device 6, the gate 5 will move in the adjusting groove 7 according to the predetermined path. With the continuous force of the control device 6, the gate 5 gradually approaches the second limit position. The second limit position is a very important node, which determines the maximum passing state of the coke flow in the adjusting groove 7.

[0060] Specifically, when the gate 5 moves to the second limit position, the limit block 9 arranged at the free end thereof starts to play a role. The limit block 9 will be in contact with and abut against the inner wall of the adjusting groove 7. The abutment is not a simple touch, but has a clear functional orientation. From the actual function, the abutment of the limit block 9 and the inner wall of the adjusting groove 7 is like setting a "terminal point" for the movement of the gate 5. It clearly defines the accurate position of the gate 5 in the second limit position, avoids the gate 5 from continuing to move forward under the action of the operating device 6, and prevents the gate 5 from completely exiting from the adjusting groove 7. Once the gate 5 completely exits from the adjusting groove 7, it will seriously affect the normal work of the double bifurcated chute, cause the coke flow to be unable to be effectively controlled, and even may cause a safety accident. In addition, the existence of the limit block 9 guarantees the stability and repeatability of the equipment operation. Each time the operating device 6 drives the gate 5 to reach the second limit position, the limit block 9 will accurately abut against the inner wall of the adjusting groove 7, so that the position of the gate 5 always remains consistent. This is crucial for accurately controlling the flow and flow direction of coke, and ensures the stability and reliability of the entire dry quenching production process, providing stable material supply conditions for the subsequent production links.

[0061] In some possible implementation embodiments disclosed in the present application, referring to Figure 1 As shown in the figure, sealing pads 10 are arranged at the connection between the sealing valve and the main chute 1, the connection between the main chute 1 and the three-way chute 4, the connection between the three-way chute 4 and the first and second bifurcated chutes 2 and 3, and the connection between the first and second bifurcated chutes 2 and 3 and the adjusting groove 7.

[0062] In this embodiment, the sealing pads 10 can fill the small gaps at the connections, form a tight sealing structure, effectively prevent coke and hot gas from leaking to the outside of the system, avoid pollution to the surrounding environment, and also prevent heat loss, thereby improving energy utilization efficiency.

[0063] When the sealing valve and the main chute 1 are connected, the main chute 1 and the three-way chute 4 are connected, the three-way chute 4 and the first and second bifurcated chutes 2 and 3 are connected, and the first and second bifurcated chutes 2 and 3 and the adjusting groove 7 are connected, a sealing pad 10 is arranged between the connecting flanges that are abutted to each other. The sealing pad 10 is clamped between the connecting flanges, can effectively fill the small gaps between the connecting flanges, ensure that each connection has good sealing performance, prevent coke, hot gas or dust from leaking from these connections during coke conveying, and ensure the stable operation of the entire dry quenching system.

[0064] Specifically, the sealing pad 10 can be a graphite composite sealing pad 10, a ceramic fiber sealing pad 10 or a polytetrafluoroethylene (PTFE) sealing pad 10, etc., which is not limited in the present application.

[0065] In some possible implementation embodiments of the present application, referring to Figure 1 As shown, the inner walls of the first branch chute 2 and the second branch chute 3 are each provided with a material blocking step 11 at a position where the inner walls contact the coke, and the material blocking step 11 is in a staggered structure. The material blocking step 11 is used to change the falling trajectory and speed of the coke, so that the coke collides and rubs with each other during the falling process.

[0066] In this embodiment, the staggered structure of the material blocking step 11 can change the motion direction of the coke which originally falls in a straight line, so that the coke forms a complex motion trajectory in the chute, avoids the coke from falling in a concentrated manner at a certain position, and makes the coke more evenly distributed in the chute, which is conducive to the stable operation of the subsequent process. At the same time, when the coke collides with the material blocking step 11, the falling speed of the coke will change due to the collision, so that the falling speed of the coke can be controlled within a suitable range, preventing the coke from causing too large an impact on the bottom of the chute or subsequent equipment due to too fast falling speed, and avoiding low conveying efficiency due to too slow speed. At the same time, when the coke passes through the material blocking step 11, the coke particles of different sizes will collide and rub with each other due to the change of the motion trajectory and speed, which is helpful to further break the larger coke particles into smaller particles, so that the coke particle size is more uniform.

[0067] The material blocking step 11 is arranged at a position where the inner walls of the first branch chute 2 and the second branch chute 3 contact the coke, so that the material blocking step 11 can directly act on the falling coke.

[0068] The material blocking step 11 is in a staggered structure, which is not a smooth or uniform structure, but a stepped structure with different heights. Such staggered arrangement can make the coke encounter different heights of the block during the falling process, thereby producing different motion changes.

[0069] Specifically, when the coke flows downward along the chute, the coke encounters the material blocking step 11, and the original straight falling path is broken. Since the height of the material blocking step 11 is staggered, the coke will be subjected to forces in different directions at different positions, thereby changing the falling direction of the coke, so that the coke no longer simply falls vertically in the chute, but forms a relatively complex and irregular motion trajectory.

[0070] In some possible implementation embodiments of the present application, referring to Figure 1 As shown, the first branch chute 2 and the second branch chute 3 are each provided with a dust removal port 12 for connecting a dust remover.

[0071] In this embodiment, by setting the dust removal port 12 and connecting the dust collector, the large amount of dust generated during the falling of the coke through the bifurcated chute can be collected in time and effectively, avoiding its emission into the surrounding environment, thereby greatly reducing the air pollution caused by the dust, reducing the dust concentration in the production site and the surrounding area, and improving the air quality.

[0072] In actual application, the dust removal port 12 is arranged on each of the first bifurcated chute 2 and the second bifurcated chute 3 to form a dust collection channel.

[0073] Specifically, each dust removal port 12 is connected with a dust collector. When the coke falls and flows in the first bifurcated chute 2 and the second bifurcated chute 3, a large amount of dust is generated due to the collision between the coals and the friction with the chute wall. At this time, the dust collector operates, and the negative pressure suction force generated thereby can suck the dust in the chute into the interior of the dust collector along the dust removal port 12.

[0074] In some possible implementation embodiments of the present disclosure, referring to Figure 1 As shown in the figure, the main chute 1 is provided with a hanging bracket 13, and the hanging bracket 13 is used to fix the main chute 1 and the civil foundation. The civil foundation is provided with a support bracket 14 at a position relative to the three-way chute 4, and the support bracket 14 is used to fix the three-way chute 4.

[0075] In this embodiment, the main chute 1 is fixed with the civil foundation by the hanging bracket 13, so that the main chute 1 can maintain a stable position during the conveying of the coke and other materials, and will not shake, shift or tilt due to the weight of the materials, the impact force generated by the flow and other factors, thereby ensuring the structural stability of the main chute 1 in the entire coke conveying system and providing a basic guarantee for the smooth conveying of the coke. The support bracket 14 is arranged at a position relative to the three-way chute 4 in the civil foundation, so that the three-way chute 4 can be fixed, preventing the three-way chute 4 from deforming or being damaged due to uneven force, ensuring that the connection between the three-way chute 4 and the main chute 1 and the bifurcated chute is tight and stable, and maintaining the integrity and reliability of the entire chute system.

[0076] The main function of the hanging bracket 13 is to fix the main chute 1 and the civil foundation. It is connected with the main chute 1 and the civil foundation by a specific connection mode, such as bolt connection, welding or other mechanical connection mode. One end is stably connected with the main chute 1, and the other end is reliably combined with the civil foundation. Thus, a stable support point is provided for the main chute 1, and the weight of the main chute 1 and various forces generated by the flow of the materials in the main chute 1 are transmitted to the civil foundation, so that the stability of the civil foundation is utilized to fix the position of the main chute 1, preventing it from moving or shaking randomly during the operation.

[0077] Wherein, in the civil foundation, the support frame 14 arranged relative to the position of the tee chute 4 can be connected with the bottom, side or other key parts of the tee chute 4, so as to disperse the force borne by the tee chute 4 to the civil foundation, ensure that the tee chute 4 maintains correct position and posture in the whole coke conveying system, and maintains good connection and cooperation between the tee chute 4 and the main chute 1 and the branch chutes, so that the coke can flow smoothly between the chutes, and problems such as poor material conveying and leakage caused by instability of the tee chute 4 are avoided.

[0078] In some possible implemented embodiments disclosed in the present application, referring to FIG. 4, Figure 1 As shown in FIG. 4, the side of the tee chute 4 away from the civil foundation is provided with a viewing window 15, which is used for observing the flow state of the coke.

[0079] In this embodiment, the operator can observe the flow state of the coke in the tee chute 4 in real time through the viewing window 15, including the flow rate, flow direction of the coke and whether there is blockage, accumulation and the like, so as to timely understand the coke conveying condition in the production process and provide intuitive basis for production control. At the same time, by observing the flow state of the coke, it can also assist in judging whether the tee chute 4 and related equipment have faults. For example, if the coke flows not smoothly, it may mean that there are problems such as wear, deformation or valve failure in the chute, so as to facilitate the maintenance personnel to prepare maintenance tools and accessories in advance and improve the maintenance efficiency.

[0080] Wherein, the viewing window 15 is a window structure with a certain size and shape opened on the tee chute 4, which can be closed by using a transparent and high-strength material such as tempered glass, so as to ensure that the operator can clearly see the internal condition of the chute, and also ensure the sealing and safety of the chute to prevent leakage of the coke and the like and entry of foreign matters from the outside.

[0081] Specifically, in actual application, the operator can directly observe the flow state of the coke in the tee chute 4 through this transparent viewing window 15 by naked eye or with the aid of some auxiliary lighting equipment and observation tools. Thus, it is determined how the coke flows from the main channel to each branch channel, whether there is unsmooth flow, blockage or abnormal flow rate and the like.

[0082] It is easy for those skilled in the art to understand that the above advantageous modes can be freely combined and superimposed without conflict.

[0083] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application. The above is merely the preferred embodiment of the present application, it should be pointed out that, for the ordinary skilled in the art, without departing from the technical principle of the present application, a number of improvements and variations can be made, these improvements and variations should also be considered as the protection scope of the present application.
