Description

Technical Field

[0001] This utility model relates to the technical field of coking production equipment, specifically to an automatic coke discharge mechanism at the tail of a coke quenching vehicle. Background Technology

[0002] The coke quenching car is an auxiliary device for large coke ovens. It generally runs on the rails on the coke side of the coke oven and is mainly used to open and close the coke oven doors, guide the hot coke pushed out of the coke oven chamber by the coke pusher car to the coke quenching car, and transport the oven doors and door frames that need to be repaired. The coke quenching car needs to be equipped with a discharge mechanism to complete the discharge treatment of the tail coke.

[0003] Currently, existing emission control systems typically use a dumping method for emissions. However, this method can lead to the accumulation of coke residue if the friction between the residues is high, which hinders normal emissions. Utility Model Content

[0004] To address the problem of accumulation and blockage in existing emission mechanisms, this invention provides an automatic coke discharge mechanism for the tail of a coke-catching vehicle.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] An automatic coke discharge mechanism for a coke quenching vehicle includes a coke box with an opening on its top surface. A top box is installed inside the opening. A lifting mechanism is provided on the top surface of the top box. The bottom end of the lifting mechanism extends into the interior of the top box and is connected to a drive box. The drive box includes a housing. The housing is slidably connected to the interior of the top box. A pushing assembly is provided on one side of the interior of the housing. The pushing assembly includes a shaft. The shaft is rotatably connected to the interior of the housing. A deflector is installed on the outer wall of the shaft. One side of the deflector extends to the bottom of the housing.

[0007] Furthermore, a cavity is provided on one side of the housing, and a motor is installed inside the cavity. The output end of the motor is connected to a drive sprocket, and a driven sprocket is fitted on one end of the shaft. Chains are respectively fitted on the outer walls of the drive sprocket and the driven sprocket, and they are connected by chain drive.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the power is transmitted to the shaft through the chain drive system composed of the driving sprocket, the driven sprocket and the chain. The chain drive has the advantages of high transmission efficiency, accurate transmission ratio and reliable operation, which can ensure the stable operation of the pushing component.

[0009] Furthermore, the lifting mechanism includes a second hydraulic cylinder, which is mounted on the top surface of the top box. The output end of the second hydraulic cylinder extends into the interior of the top box and is connected to the top surface of the box.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the lifting and lowering of the drive box can be precisely controlled by the extension and retraction of the second hydraulic cylinder, thereby adjusting the working height of the pushing assembly to adapt to different tail coke discharge requirements. Furthermore, the lifting mechanism also includes limit rods; circular holes are respectively opened on both sides of the top surface of the top box, and limit rods are slidably connected inside the two circular holes, with the bottom ends of the two limit rods connected to the top surface of the box.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the limit rod plays a guiding role, ensuring that the drive box maintains stable vertical movement during the lifting process and preventing it from tilting or shaking.

[0012] Furthermore, a box cover is hinged to one side of the tail coke box, and side pushing mechanisms are respectively installed at an angle on both sides of the tail coke box near the box cover.

[0013] The beneficial effect of adopting the above-mentioned further solution is that it enables the opening and closing of the coke box. Opening the box cover during coke discharge facilitates smooth discharge; closing the cover during non-discharge operations prevents coke leakage and the entry of external impurities into the coke box, thus protecting the equipment.

[0014] Furthermore, the side-pushing mechanism includes a first hydraulic cylinder and a fixed seat. The fixed seat is installed on the outer wall of the tail coke box. The first hydraulic cylinder is rotatably connected to one side of the fixed seat. A movable seat is installed at the output end of the first hydraulic cylinder. The first hydraulic cylinder is rotatably connected to one side of the box cover through the movable seat.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the extension and retraction action of the first hydraulic cylinder can provide power for the opening and closing of the box cover, and the rotational connection allows the opening and closing angle of the box cover to be flexibly adjusted, which facilitates the discharge of tail coke.

[0016] Furthermore, an inclined ramp is installed at the bottom of the interior of the tail coke box.

[0017] The beneficial effects of adopting the above-mentioned further scheme are that the inclined slope can use gravity to assist the coke to move towards the opening of the tail coke box, reduce the working resistance of the pushing component, improve the efficiency of tail coke discharge, and at the same time make the tail coke discharge more thorough and reduce the amount of tail coke residue in the tail coke box.

[0018] Furthermore, the interior of the enclosure is filled with heat insulation panels.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the heat insulation plate can effectively block the heat generated by the tail coke from being transferred to the motor and other equipment inside the drive box, thereby avoiding damage to the equipment caused by high temperature.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This automatic coke discharge mechanism for coke quenching vehicles, through the cooperation of an opening, a top box, a lifting mechanism, a drive box, and a pushing component, can effectively clean up the coke tail, thereby reducing accumulation and blockage. Specifically, the opening provides space for the top box, and the lifting mechanism causes the box to rise and fall, allowing the pushing component inside the box to fall to a designated position and contact the coke tail. Then, the power output from the drive box causes the shaft to rotate the lever, thereby pushing the coke tail out of the coke box. Attached Figure Description

[0033] Please see Figures 1-5 This utility model provides a technical solution: an automatic coke discharge mechanism for a coke-catching vehicle, including a coke box 100, an opening 800 on the top surface of the coke box 100, a top box 400 installed inside the opening 800, a lifting mechanism 500 on the top surface of the top box 400, the bottom end of the lifting mechanism 500 extending into the interior of the top box 400 and connected to a drive box 600, the drive box 600 including a box body 6001, the top box 400 being slidably connected to the box body 6001, a pushing assembly 700 on one side of the interior of the box body 6001, the pushing assembly 700 including a shaft 7001, the box body 6001 being slidably connected to the top box 400, and the push assembly 700 including a shaft 7001. The internal rotating connecting shaft 7001 is 001. A lever 7002 is installed on the outer wall of the shaft 7001. One side of the lever 7002 extends to the bottom of the box 6001. The opening 800 provides space for the top box 400. The lifting mechanism 500 causes the box 6001 to lift, so that the pushing component 700 in the box 6001 can fall to the designated position and contact the tail coke. Then, the power output in the drive box 600 causes the shaft 7001 to drive the lever 7002 to rotate, thereby pushing the tail coke out of the tail coke box 100.

[0034] 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.

[0035] As an embodiment of this utility model, a cavity is further provided on one side of the housing 6001, and a motor 6002 is installed inside the cavity. The output end of the motor 6002 is connected to a drive sprocket 6003. A driven sprocket 6004 is fitted on one end of the shaft 7001. Chains 6005 are respectively fitted on the outer walls of the drive sprocket 6003 and the driven sprocket 6004, and are connected by the chain 6005. The chain drive system composed of the drive sprocket 6003, the driven sprocket 6004 and the chain 6005 transmits power to the shaft 7001. The chain drive has the advantages of high transmission efficiency, accurate transmission ratio and reliable operation, which can ensure the stable operation of the pusher assembly 700.

[0036] As an embodiment of this utility model, the lifting mechanism 500 further includes a second hydraulic cylinder 5001. The second hydraulic cylinder 5001 is installed on the top surface of the top box 400. The output end of the second hydraulic cylinder 5001 extends into the interior of the top box 400 and is connected to the top surface of the box body 6001. Through the extension and retraction of the second hydraulic cylinder 5001, the lifting and lowering of the drive box 600 can be precisely controlled, thereby adjusting the working height of the pusher assembly 700 to adapt to different tail coke discharge requirements. The lifting mechanism 500 also includes a limiting rod 5002. Circular holes are opened on both sides of the top surface of the top box 400. The limiting rod 5002 is slidably connected to the interior of the two circular holes. The bottom ends of the two limiting rods 5002 are connected to the top surface of the box body 6001. The limiting rod 5002 plays a guiding role to ensure that the drive box 600 maintains stable vertical movement during the lifting and lowering process and prevents it from tilting or shaking.

[0037] As an embodiment of this utility model, further, a cover 200 is hinged to one side of the coke box 100. Side-pushing mechanisms 300 are respectively installed obliquely on both sides of the coke box 100 near the cover 200, enabling the opening and closing of the coke box 100. When discharging coke, the cover 200 is opened to facilitate smooth discharge; when not discharging, the cover 200 is closed to prevent coke leakage and the entry of external impurities into the coke box 100, thus protecting the equipment. The side-pushing mechanism 300 includes a first hydraulic cylinder 3001 and a fixed... A fixed seat 3002 is installed on the outer wall of the coke box 100. A first hydraulic cylinder 3001 is rotatably connected to one side of the fixed seat 3002. A movable seat 3003 is installed at the output end of the first hydraulic cylinder 3001. The first hydraulic cylinder 3001 is rotatably connected to one side of the box cover 200 through the movable seat 3003. The extension and retraction of the first hydraulic cylinder 3001 can provide power for the opening and closing of the box cover 200. The rotatable connection allows the opening and closing angle of the box cover 200 to be flexibly adjusted, which is convenient for the discharge of coke.

[0038] As an embodiment of this utility model, a slope 900 is further installed at the bottom of the coke box 100. The slope 900 can use gravity to assist the coke to move towards the opening of the coke box 100, reduce the working resistance of the pushing component 700, improve the efficiency of coke discharge, and make the coke discharge more thorough, reducing the amount of coke residue in the coke box 100. The interior of the box 6001 is filled with a heat insulation plate, which can effectively block the heat generated by the coke from being transferred to the motor 6002 and other equipment inside the drive box 600, thereby avoiding damage to the equipment due to high temperature.

[0039] Specifically, the working principle of this automatic coke discharge mechanism for the coke chute is as follows: When coke needs to be discharged, the side-push mechanism 300 starts working, and the first hydraulic cylinder 3001, which is rotatably connected to the fixed seat 3002 on the outer wall of the coke box 100, is activated, and the output end of the first hydraulic cylinder 3001 extends. Since the first hydraulic cylinder 3001 is rotatably connected to one side of the box cover 200 through the movable seat 3003, the thrust generated by the extension of the first hydraulic cylinder 3001 causes the box cover 200 to rotate around its hinge point with the coke box 100, thereby opening the box cover 200 and creating conditions for coke discharge. The lifting mechanism 500 then comes into play. The second hydraulic cylinder 5001, installed on the top surface of the top box 400, is activated, and its output end extends downward, pushing the box body 6001 of the drive box 600 connected to it to slide downward inside the top box 400. Meanwhile, the limiting rods 5002, which are slidably connected in the circular holes on both sides of the top surface of the top box 400, serve as guides and stabilizers, ensuring that the box 6001 descends vertically until the pushing assembly 700 reaches the appropriate working position, ready for the tail coke pushing operation. The motor 6002 inside the drive box 600 starts, and the output end of the motor 6002 drives the drive sprocket 6003 to rotate. The drive sprocket 6003 is connected to the driven sprocket 6004 mounted on one end of the shaft 7001 via a chain 6005, thus causing the shaft 7001 to rotate inside the box 6001. The lever 7002 installed on the outer wall of the shaft 7001 rotates with the shaft 7001, extending to the bottom of the box 6001. During rotation, the lever 7002 pushes the tail coke inside the tail coke box 100. The inclined ramp 900 installed at the bottom of the tail coke box 100 uses gravity to assist the tail coke in moving towards the opening of the tail coke box 100. With the push of the feeding assembly 700 and the assistance of the inclined ramp 900, the tail coke is smoothly discharged from the opening of the tail coke box 100. After the tail coke is discharged, the motor 6002 stops rotating, and the feeding assembly 700 stops pushing. The output end of the second hydraulic cylinder 5001 retracts, driving the box body 6001 of the drive box 600 to rise back to the initial position. Subsequently, the output end of the first hydraulic cylinder 3001 retracts, pulling the box cover 200 to rotate around the hinge point, closing the box cover 200, and restoring the entire mechanism to its initial state, ready for the next tail coke discharge operation.
