Description

Technical Field

[0001] This utility model relates to the field of metallurgical coking technology, and in particular to an adaptive coke oven coke plate cleaning device. Background Technology

[0002] During coke oven production, the oven door needs to be opened to push the mature coke out of the carbonization chamber. During the opening of the oven door and pushing of coke, tar, coke, coke powder and other debris fall from the oven door, oven frame and mature coke cake. The fallen debris falls onto the coke oven's coke tray and is difficult to clean effectively.

[0003] Currently, the above-mentioned debris is mostly cleaned manually on site, which is labor-intensive for operators and has poor cleaning results. It is also not conducive to unmanned operation and production of coke ovens.

[0004] Existing technologies have several drawbacks in practical use, including blind spots during cleaning, excessive dust during the cleaning process, incompatibility between multiple hydraulic cylinders, and damage to the coke tray. These issues pose safety hazards, low dust removal efficiency, environmental pollution, and high labor intensity. Specifically: 1) The cleaning mechanism requires multiple hydraulic cylinders to work together to sweep away debris from the coke tray. However, the coke tray near the high-temperature furnace opening is prone to deformation, making it difficult to achieve this operation using adaptive cylinder coordination. 2) Pre-coating the coke tray with a coating to prevent debris adhesion is ineffective and can cause secondary pollution. 3) Using vertical hydraulic cylinders to drive the cleaning of the coke tray results in the cleaning head operating perpendicular to the cleaning direction, damaging both the cleaning head and the coke tray. 4) While a cleaning robot is designed to clean the coke tray in front of the furnace, space constraints are not considered, the robot interferes with the main functions, rendering it unusable and disrupting normal production by occupying equipment operating time. 5) The blowing mechanism fixed on the coke guide grid can clean up the debris on the coke plate, but it cannot effectively remove it and will cause secondary pollution. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this utility model is to provide an adaptive coke oven coke plate cleaning device.

[0008] Furthermore, torsion springs are respectively sleeved on the left and right sides of the connecting shaft; torsion spring fixing blocks are provided at the inner ends of the torsion springs; the torsion spring fixing blocks are coaxially fixed to the connecting shaft by pins; one connector of the inner end of the torsion spring is inserted into the torsion spring fixing block, and the other connector is inserted into the middle of the sweeping plate, and the torsion spring always applies a downward force to the sweeping plate.

[0009] Furthermore, both ends of the connecting shaft are fixedly connected to the fixing frame via baffles.

[0010] Furthermore, a limiting baffle is fixedly connected to the lower part of the front end face of the fixing frame; in the initial state, the upper end face of the cleaning plate is in contact with the bottom of the limiting baffle.

[0011] Furthermore, the cleaning head is fixed to the front end of the cleaning plate by bolts.

[0012] Furthermore, a heat-resistant plate is provided on the front end face of the fixing frame.

[0013] Furthermore, the device also includes a collection hopper; the collection hopper is located below the rear end of the coke oven coke flow plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The cleaning device consists of a cylinder and two torsion springs, eliminating the need for multiple hydraulic cylinders to work together to clean debris from the coke tray, making it easy to operate.

[0016] 2. Overcoming the problem of high-temperature deformation of the coke oven plate. Under the action of the torsional torque generated by the torsion spring, the cleaning head is always in contact with the coke oven plate and automatically adapts to the changes in the surface properties of the plate, scraping away debris on the plate.

[0017] 3. It relies on the sweeping head to sweep, without blowing action, thus reducing secondary pollution.

[0018] 4. The sweeping head's running direction is not perpendicular to the sweeping direction, making it less likely to damage the sweeping head and the slag removal plate.

[0019] 5. The operation process of the frame cleaning machine has been optimized. The cleaning device operates together with the frame cleaning machine without taking up extra time or affecting equipment operation time, allowing for normal production. Attached Figure Description

[0030] See appendix Figures 1-3 The present invention proposes an adaptive coke oven coke plate cleaning device, which includes a frame cleaning machine 2, a fixed frame 3, a cylinder 4, a cleaning plate 5, a cleaning head 6, and a connecting shaft 7.

[0031] The frame cleaning machine 2 is located above the coke oven coke-flowing plate 1, which is an essential piece of equipment for the coke oven and is fixed below the furnace door of the coke side carbonization chamber. The frame cleaning machine 2 is a specialized mechanical device for the coke oven and is fixed to the mechanical equipment. It is driven by a hydraulic cylinder to move forward and backward, and completes the cleaning of the furnace frame through the furnace frame surface scraper 2-1, the furnace frame inner scraper 2-2, and the furnace bottom scraper 2-3.

[0032] The fixed frame 3 is vertically fixed to the lower side of the steel structure in the middle of the rear end of the frame cleaning machine 2; the cylinder 4 is vertically set on the lower side of the rear end face of the fixed frame 3, and an ear plate is fixedly connected to the middle of the rear end face of the fixed frame 3. The tail of the cylinder 4 is hinged to the ear plate in the middle of the rear end face of the fixed frame through a pin; the cleaning plate 5 is set below the fixed frame 3 and corresponds to the longitudinal position of the coke oven coke flow plate 1; the rear side of the cleaning plate 5 is hinged to the bottom of the fixed frame 3 through a connecting shaft 7, and the hinge point is 5a; the two ends of the connecting shaft 7 are respectively fixed to the fixed frame 3 through baffles 11; the rear end of the cleaning plate 5 is hinged to the head of the cylinder 4, and the hinge point is 5c; the cleaning head 6 is fixed to the front end of the cleaning plate 5 by bolts, and the cleaning head 6 is in contact with the surface of the coke oven coke flow plate 1.

[0033] By controlling the cylinder 4, the cleaning plate 5 can be rotated, which in turn drives the cleaning head 6 to clean the surface of the coke oven coke-dripping plate 1.

[0034] The control principle of the cylinder is as follows: Figure 7 As shown, a two-position three-way solenoid valve 14 is connected to the air inlet of the rodless chamber; in the air intake state, the cylinder rod extends, and the solenoid valve switches to the air intake state; in the air release state, the cylinder rod retracts, and the solenoid valve switches to the air release state.

[0035] like Figures 4-6 As shown, in this embodiment, torsion springs 8 are respectively sleeved on the left and right sides of the connecting shaft 7; torsion spring fixing blocks 10 are provided at the inner ends of the torsion springs 8; the torsion spring fixing blocks 10 are coaxially fixed to the connecting shaft by pins 9; one connector 8a of the inner end of the torsion spring 8 is inserted into the recess 10a in the middle of the torsion spring fixing block 10, and the other connector 8b is inserted into the recess 5b in the middle of the upper end face of the sweeping plate 5; the torsion spring 8 is fixed at 8a and rotates together with the sweeping plate 5 at 8b, generating torque; the torsion spring 8 always provides downward torque to the sweeping plate 5.

[0036] In this embodiment, an inclined limiting baffle 12 is fixedly connected to the lower part of the front end face of the fixing frame 3; in the initial state, the front side of the upper end of the cleaning plate 5 is in contact with the bottom of the limiting baffle 12 to block the cleaning plate 5 and prevent it from running beyond the limit.

[0037] The front end of the fixed frame 3 is provided with a heat-proof plate 13 to prevent the high temperature inside the carbonization chamber from baking the cylinder 4 and the torsion spring 8.

[0038] The device also includes a collection hopper 15; the collection hopper 15 is located below the rear end of the coke oven coke flow plate 1 and is used to collect debris that is scraped off.

[0039] The specific workflow of this utility model is as follows:

[0040] The initial state of this device is as follows: Figure 1As shown, at this time, the solenoid valve switches to the air intake state, the cylinder rod of cylinder 4 extends, passes through 5c, and pushes the cleaning plate 5 to rotate around 5a. At the same time, it drives the torsion spring 8 fixed at 5b to rotate, generating a torsional torque. This ensures that the cleaning head 6 fixed at the front end of the cleaning plate 5 maintains a safe distance from the coke oven coke-flowing plate 1.

[0041] Start the frame cleaning machine 2 to clean the coke oven frame from top to bottom. The cleaned debris falls to the bottom of the oven. After the frame cleaning machine 2 moves back 1 meter, the bottom scraper 2-3 contacts the bottom of the oven and hooks the frame cleaning debris out of the carbonization chamber and onto the coke oven coke flow plate 1.

[0042] After stopping and restarting, the frame cleaning machine 2 advances 1 meter, then the solenoid valve of cylinder 4 is switched to the venting state; the torsion spring 8 twists, generating a torsional torque that drives the cleaning plate 5 to rotate counterclockwise, and the cleaning head 6, driven by the cleaning plate 5, comes into contact with the coke oven coke-flowing plate 1; the frame cleaning machine 2 starts to retreat again, and under the action of the torsional torque generated by the torsion spring 8, the cleaning head 6 always remains in contact with the surface of the coke oven coke-flowing plate 1, and automatically adapts to changes in the surface properties of the coke-flowing plate, scraping away debris on the coke oven coke-flowing plate 1, so that the debris finally falls into the collection hopper 15, such as... Figure 2 As shown.

[0043] After reaching the final cleaning position, the cylinder rod of cylinder 4 retracts completely, completing the cleaning work; the solenoid valve is activated to switch to the air intake state, the cylinder rod of cylinder 4 extends, and the device returns to the initial state, thus completing one work cycle.

[0044] Matters not covered in this utility model are common knowledge.
