Description

Technical Field

[0001] This utility model relates to the field of coking technology, and more particularly to a tail coke discharge device, and more specifically, a tail coke quenching and collection device for a 6m top-loading coke oven. Background Technology

[0002] The coke discharge from a 6m top-loading coke oven requires equipment such as coke quenching cars and coke quenching trolleys. For a long time, the coke quenching car has used a scraper conveyor mechanism to quench and transport the tail coke (referred to as tail coke) during the production process. Because the tail coke is in direct contact with the scraper conveyor mechanism, it is prone to causing the scraper conveyor chain to jam, frequently resulting in chain breakage and other malfunctions. Frequent scraper conveyor failures force the coke quenching car to stop operating, making the cleaning of the tail coke impossible. This leads to the long-term accumulation of red-hot coke, which can easily damage the onboard equipment and pose a risk to the normal coke guiding and discharge process. Therefore, how to avoid the inability to carry out cleaning work normally due to coke quenching car malfunctions is a problem that needs to be solved. Utility Model Content

[0003] This utility model provides a tail coke quenching and collection device for a 6m top-loading coke oven, which avoids the coke blocking car malfunction caused by direct contact between the scraper conveyor mechanism and the tail coke, thereby ensuring the normal operation of tail coke cleaning.

[0004] To achieve the above objectives, this utility model provides a tail coke quenching and collection device for a 6m top-loading coke oven. The device comprises a receiving hopper, an upper water tank, a high-pressure water pump, a coke-water separation hopper, and a tail coke chute. The receiving hopper, upper water tank, high-pressure water pump, and tail coke chute are mounted on a coke quenching car, while the coke-water separation hopper is mounted on a coke quenching trolley. The receiving hopper is located below the tail coke outlet of the coke oven. The tail coke chute is a trough-shaped structure with open ends and an inclined arrangement. The top of the tail coke chute is connected to the receiving hopper. The upper water tank is connected to the top of the tail coke chute via the high-pressure water pump. The top of the coke-water separation hopper has a feed inlet located below the tail coke chute, and the diameter of the feed inlet is larger than the diameter of the bottom of the tail coke chute. A screen for separating the tail coke and water is also provided inside the coke-water separation hopper.

[0005] Furthermore, the quenching trolley is also equipped with a water collection tank, the inlet of which is connected to the outlet of the coke-water separation hopper.

[0006] Furthermore, the water collection tank is equipped with a vertical partition that divides the interior of the water collection tank into a front chamber and a rear chamber; a predetermined gap is left between the top of the partition and the inner top wall of the water collection tank; the water inlet of the water collection tank is connected to the front chamber, and the water outlet of the water collection tank is connected to the rear chamber.

[0007] Furthermore, the quenching trolley is also equipped with a return water pump. The outlet of the water collection tank is connected to the inlet of the return water pump, and the outlet of the return water pump is connected to the upper water tank through a detachable pipeline.

[0008] Furthermore, the detachable piping includes a return water hose and a snap-fit ​​connector installed between the return water hose and the return water pump, with the starting end of the return water hose connected to the upper water tank.

[0009] Furthermore, the quenching trolley is also equipped with a hose lifting device for raising and lowering the return water hose.

[0010] Furthermore, the water collection tank is also equipped with a parallel connecting pipe, and a shut-off valve is installed on the parallel connecting pipe.

[0011] Furthermore, the tail coke quenching and collection device of the 6m top-loading coke oven also includes a chute cover for covering the tail coke chute.

[0012] Furthermore, the coke quenching car includes a frame and a coke quenching car traveling mechanism that can run along the coke quenching track. The frame is connected to the coke quenching car traveling mechanism. The receiving hopper, upper water tank, high-pressure water pump and tail coke chute are all fixedly connected to the frame.

[0013] Furthermore, the quenching trolley includes a car body and a quenching trolley traveling mechanism that can run along the quenching track. The car body is connected to the quenching trolley traveling mechanism. The water collection tank and the return water pump are both fixedly connected to the car body.

[0014] The above technical solution has the following beneficial effects:

[0015] In this technical solution, after the tail coke is introduced into the tail coke chute, it is flushed with high-pressure water, which allows the tail coke to be quickly extinguished and smoothly transported to the coke-water separation hopper set on the quenching trolley. This avoids the conveyor chain jamming and disconnection caused by direct contact between the scraper conveyor mechanism and the tail coke in the prior art, ensuring that the coke quenching car can be used normally, thereby ensuring the normal operation of production and improving the tail coke processing capacity.

[0016] In addition, this technical solution also has the following characteristics:

[0017] 1) By using chute cover plates for conveying, the exposure of workers to the harsh coking environment can be reduced, and the contact time between workers and dust and smoke can be reduced, thus effectively improving the safety and occupational health of employees.

[0018] 2) By setting up chute covers, the high-temperature water vapor generated when the hot coke in the tail coke chute is cooled by water can be sealed inside the tail coke chute, thereby preventing the water vapor from escaping and reducing excessive moisture loss.

[0019] 3) The coke collected by the coke-water separation bucket can be intermittently transferred to the coke drying platform, avoiding the environmental problems caused by smoke during the process of putting wet coke into the coke can for red coking in the existing technology.

[0020] 4) In the existing technology, it is necessary to frequently clean and replace the tail coke belt, which greatly increases the workload of the job. After adopting this technical solution, it is no longer necessary to install belts and other components, thus reducing the workload of cleaning and maintaining the belts. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 , Figure 2 , Figure 3As shown in the figure, this utility model embodiment provides a tail coke quenching and collection device for a 6m top-loading coke oven, including a receiving hopper, an upper water tank 9, a high-pressure water pump 1, a coke-water separation hopper 3, and a tail coke chute 2. The receiving hopper, the upper water tank 9, the high-pressure water pump 1, and the tail coke chute 2 are arranged on a coke quenching car 100, and the coke-water separation hopper 3 is arranged on a coke quenching trolley 200. The receiving hopper is located below the tail coke outlet of the coke oven, and the tail coke chute 2 has two ends. The open, inclined trough-shaped structure has the top of the tail coke chute 2 connected to the receiving hopper; the upper water tank 9 is connected to the top of the tail coke chute 2 via the high-pressure water pump 1; the coke-water separation hopper 3 has an inlet 11 at its top, located below the tail coke chute 2, and the diameter of the inlet 11 is larger than the diameter at the bottom of the tail coke chute 2; the coke-water separation hopper 3 is also equipped with a screen for separating tail coke and water.

[0028] To address the aforementioned issues, this application no longer employs the existing scraper conveyor mechanism for coke quenching and feeding. Instead, it utilizes hydraulic power as the conveying force to form a tail coke quenching and collection device that uses water to transport and quench coke. To adapt to the actual environment of a 6m top-loading coke oven, this device adopts a split design. Specifically, some components (collecting hopper, upper water tank, high-pressure water pump 1, and tail coke chute 2, etc.) are mounted on a coke quenching trolley 200 (coke-water separation hopper 3, etc.) that runs along the top track, while other components are mounted on a coke quenching trolley 200 that runs along the ground track. The tail coke chute 2 is an inclined trough structure with open ends. The top of the coke-water separation hopper 3 is provided with an inlet 11 for receiving the tail coke that slides down from the tail coke chute 2 (the diameter of the inlet 11 is larger than the diameter of the bottom of the tail coke chute 2). During operation, after the coke quenching car 100 and the coke quenching trolley 200 are positioned (at this time, the coke quenching trolley 200 should be moved to the side and below the coke quenching car 100, and the coke-water separation hopper 3 should be located directly below the output end of the tail coke chute 2), the coke output from the tail coke outlet of the coke oven falls into the receiving hopper set on the coke quenching car 100, and then enters the tail coke chute 2 connected to the receiving hopper. At the same time, water in the upper water tank 9 is sprayed into the tail coke chute 2 through the high-pressure water pump 1. The coke is moved to the coke-water separation hopper 3 below by the flushing action of the water. During the conveying process, the red-hot coke is extinguished by the water, so the coke extinguishing and collection operation is very convenient. After entering the coke-water separation hopper 3, because the mesh size of the screen is smaller than the size of the coke, the extinguished coke is separated from the water. When the coke in the coke-water separation hopper 3 is full, it can be transferred to the matching coke drying platform area. In this technical solution, the preferred form of the tail coke chute 2 is a square trough with rounded corners welded to the back, and it is made of stainless steel. Furthermore, to avoid waste, a water collection tank 4 can be installed on the coke quenching trolley 200. The inlet of the water collection tank 4 is connected to the outlet of the coke-water separation bucket 3, so that the water separated in the coke-water separation bucket 3 flows into the water collection tank 4 for collection.

[0029] Furthermore, the water separated from the coke-water separation hopper 3 still contains impurities (mainly coke powder). To further purify the water, the water collection tank 4 can be designed as an overflow structure. That is, a vertical partition is installed inside the water collection tank 4, which divides the interior of the water collection tank 4 into a front chamber and a rear chamber. The coke powder settles and settles in the front chamber. When the liquid level in the front chamber exceeds the top of the partition (the top of the partition does not touch the top of the inner side of the water collection tank 4), the water at the top layer flows over the partition to the rear chamber, so that all the purified water enters the rear chamber. In subsequent work, the purified water can be taken from the rear chamber. A drain outlet can be installed at the bottom of the front chamber to periodically discharge the sediment.

[0030] Furthermore, the purified water collected in the rear chamber of the water collection tank 4 can be pumped back to the upper water tank 9 of the coke quenching car 100 via the return water pump 5 to achieve water recycling. However, since the relative positional relationship between the coke quenching car 100 and the coke quenching trolley 200 is not fixed, a fixed pipeline cannot be used between the return water pump 5 and the upper water tank. Therefore, in this application, a detachable pipeline is used to connect the two, and an intermittent return water method is adopted to avoid affecting the passage of the coke quenching trolley. When return water is needed, the detachable pipeline is connected, and the return water pump 5 is started to transport the water in the rear chamber back to the upper water tank 9. In addition, a filter can be installed at the outlet of the water collection tank 4, and the water collection tank 4 is connected to the inlet of the return water pump 5 through the filter. This allows for further filtration, such as using a finer filter screen, to further ensure smooth return water to the upper water tank 9.

[0031] Furthermore, a preferred embodiment of the detachable pipeline is that a return water hose 6 connected to the upper water tank is installed on the coke quenching car 100. Before the return water operation is required, the return water hose 6 can be quickly connected to the return water pump 5 to improve working efficiency. The snap-fit ​​connector 7 (commonly known as a quick connector or fast coupling) can be an existing product, which consists of two matching parts. One part is set on the coke quenching car 100 and connected to the end of the return water hose 6, and the other part is set on the coke quenching trolley 20 and connected to the return water pump 5. After the two parts are connected, a closed-loop water circuit can be formed. After loosening, the return water hose 6 can be lifted, and the coke quenching trolley 20 can be driven away.

[0032] Furthermore, for ease of operation, a hose lifting device (e.g., a small winch) can be installed on the coke quenching car 100 to raise the return water hose 6. When return water is needed, the hose lifting device raises the end of the return water hose 6 (the end connected to the snap-fit ​​connector 7), thereby connecting the return water hose 6 to the return water pump 5 via the snap-fit ​​connector 7. After the return water is completed, the connection between the return water hose 6 and the return water pump 5 is disconnected, and the return water hose 6 is raised to avoid affecting the passage of the coke quenching trolley. Actual testing shows that with the snap-fit ​​connector 7 (quick connector), the quick connection or disconnection between the return water hose 6 and the return water pump 5 can be completed within 10 seconds, which is much faster than ordinary clamp connections or threaded connections, significantly improving work efficiency.

[0033] Furthermore, since the water collection tank 4 on a single quenching trolley 200 has a limited volume, while the water demand of the upper water tank is relatively large (in one specific embodiment, the volume of a single water collection tank is approximately 2.5m³), 3 The upper water tank has a volume of 8m³. 3Therefore, to better improve water collection capacity and meet the needs of the upper water tank with minimal water return cycles, a parallel connecting pipe can be installed on each water collection tank 4. This parallel connecting pipe is then connected to the water collection tanks of the two quenching trolleys 200 via flexible hoses, thus increasing the effective volume. During subsequent water return cycles, water can be simultaneously extracted from all water collection tanks 4. For example, if only one quenching trolley 200's water collection tank 4 is used for storage, water must be returned immediately once full, otherwise there is no more storage space. However, if both quenching trolleys 200's water collection tanks 4 are stored simultaneously, the time required to fill is doubled, which correspondingly extends the interval between water return operations, thereby reducing workload.

[0034] Furthermore, the tail coke quenching and collection device of the 6m top-loading coke oven also includes a chute cover plate for covering the tail coke chute 2. Through the sealing effect of the chute cover plate, the high-temperature water vapor generated in the tail coke chute 2 due to the cooling of the high-temperature red coke when it comes into contact with water can be sealed in the chute, thereby preventing the water vapor from escaping and reducing the phenomenon of excessive water loss.

[0035] Furthermore, the coke quenching car 100 includes a frame and a coke quenching car traveling mechanism that can run along the coke quenching track. The frame is connected to the coke quenching car traveling mechanism. The receiving hopper, the upper water tank, the high-pressure water pump 1, and the tail coke chute 2 are all fixedly connected to the frame. The frame is the main structure of the coke quenching car, welded from high-strength steel, used to support and install other components, and must have sufficient strength and rigidity to withstand various loads during operation. The coke quenching car traveling mechanism generally consists of a motor, a reducer, wheels, etc., driving the coke quenching car 100 to move smoothly on the coke quenching track and achieve accurate positioning. Meanwhile, the coke oven quenching car 100 is also equipped with a door opening and closing device (driven by a hydraulic system or electric push rod, including door hooks, opening and closing mechanisms, etc.) for opening and closing the coke oven doors, a dust collection device (including dust collection hoods, pipes, valves, and dust collection equipment), and corresponding hydraulic and electrical control systems (controlling various actions of the coke oven quenching car 100, including starting, stopping, and speed adjustment of the motor, as well as valve opening and closing of the hydraulic system, usually controlled by PLC).

[0036] Further, the coke quenching trolley 200 includes a vehicle body and a coke quenching trolley traveling mechanism capable of running along the coke quenching track, and the vehicle body is connected to the coke quenching trolley traveling mechanism; the water collection tank 4 and the water return pump are both fixedly connected to the vehicle body. The vehicle body is the bearing part of the coke quenching trolley 200 and is welded by steel plates; the coke quenching trolley traveling mechanism is similar to the coke guide car traveling mechanism and consists of a motor, a reducer, wheels, etc., enabling the coke quenching trolley 200 to accurately run on the track and cooperate with the coke guide car 100 and the coke oven; a frame connection device is also provided between the vehicle body and the coke quenching trolley traveling mechanism for ensuring reliable connection and force transmission between the two, while allowing a certain degree of relative movement to adapt to the unevenness of the track and the change of the running attitude of the vehicle; the coke quenching trolley 200 is also provided with a braking device, including components such as a brake and a brake wheel, for accurately stopping when the coke quenching trolley 200 runs to a designated position and quickly braking in case of an emergency to ensure the safety of equipment and personnel; in addition, the coke quenching trolley 200 is also provided with a corresponding electrical control system for controlling the traveling, braking and other actions of the coke quenching trolley 200.

[0037] It should be noted that the high-pressure water pump 1 can be integrally designed with the upper water tank 9, so Figure 1 、 Figure 3 no separate indication of the high-pressure water pump 1 is made again; similarly, the water return pump 5 can also be integrally designed with the water collection tank 4, so Figure 1 、 Figure 3 no separate indication of the water return pump 5 is made again.

[0038] The technical solution of the present application will be described in detail below with a specific embodiment:

[0039] This specific embodiment includes a high-pressure water power device (high-pressure water pump 1) installed on the coke guide car 100, a tail coke chute 2, a return water hose 6, a hose lifting device 8, and a coke-water separation hopper 3, a water collection tank 4, a water return pump 5, etc. installed on the coke quenching trolley 200. When the tail coke at the furnace head falls into the tail coke chute 2, it is cooled and quenched by using the high-pressure water sent by the high-pressure water pump 1, and is transported to the coke-water separation hopper 3 by the power provided by the high-pressure water. The separation of coke and water is carried out in the coke-water separation hopper 3. After the coke accumulates and fills up in the coke-water separation hopper 3, it is transferred to the coke drying platform area supporting the coke oven. The water separated by the coke-water separation hopper 3 enters the water collection tank 4. After standing and separating the coke powder, it can be transported back to the high-pressure water pump 1 through the return water hose 6 by the water return pump 5 for recycling.

[0040] In the application process, the power for coke transportation is provided by high-pressure water, and the high-temperature coke is quenched by the water flow during transportation.

[0041] By utilizing the elevation difference between the coke quenching car 100 and the coke quenching trolley 200, a coke-water separation hopper 3 is installed on the coke quenching trolley 200 to collect coke and water. A screen filtration device is designed in the coke-water separation hopper 3 to realize the function of storing coke in the coke-water separation hopper and allowing water to flow into the water collection tank 4 by gravity, thereby achieving the goal of separating coke and water.

[0042] A partition is designed inside the water collection tank 4 to divide the water collection tank into a front chamber and a rear chamber. After the water is collected in the front chamber, it has a settling time to allow the coke powder to settle at the bottom of the front chamber. The water flows into the rear chamber, achieving the goal of separating the coke powder from the water.

[0043] Both the coke-water separation hopper 3 and the water collection tank 4 are designed with storage functions to realize the intermittent recovery of coke and water. They are matched with the coke production of the 6m top-loading coke oven and solve the problem of continuous recovery affecting the coke oven operation time.

[0044] A hose lifting device is installed in the coke quenching car 100. When collecting water from the water tank 4, the return water hose 6 is lowered and connected to the outlet of the return water pump through the snap-fit ​​connector 7 at the end of the return water hose 6, thereby forming a loop for return water operation. When the coke oven is in normal production, the return water hose 6 is raised by the hose lifting device to eliminate the problem of the fixed return water hose 6 obstructing the passage of the coke quenching trolley 200.
