Description

Technical Field

[0001] The invention relates to a thermal insulation cover technology, in particular to a foldable thermal insulation cover device for a vehicle-mounted coke tank. Background Art

[0002] The continuous expansion of coke oven capacity is primarily achieved by increasing the oven height while maintaining the same oven width. With a fixed oven spacing, the length of the coke drum floor trolley is also limited, and the passive increase in the coke drum's carrying capacity can only be achieved by increasing the drum diameter. The space above the coke drum mouth and the coke guide grid and dust hood is narrow. In some production lines, the lower end of the guide rails on the elevator and the insulation board under the bottom crossbeam are even low, resulting in a small clearance above the coke drum mouth. The online dual coke drums are operated in a continuous alternating cycle, producing one furnace of coke every 10-15 minutes on average. The added time of the additional process steps affects the production rhythm.

[0003] In response to the above technical problems, this application proposes a solution. Summary of the Invention

[0004] The purpose of the present invention is to install a pair of foldable insulation covers on the coke tank trolley through clever design, which is responsible for opening and closing the insulation covers as needed during the ground transportation of the coke tank, reducing the combustion of exposed coke and its smoke and dust emissions, while reducing the burnt loss of coke. The use of a double-open tank cover plus folding technology can ensure that all devices do not exceed the range of the vehicle body, including the range of action, which does not exceed the original facilities and process limitations. It also ensures that the coke tank is in a fully open state when receiving coke, and the cover opening operation can be carried out simultaneously during the movement of the coke tank trolley, which actually does not increase any process time. After the coke tank trolley receives the tank at this station or the intermediate trolley is in place, it is closed one meter first and the coke tank trolley can be moved immediately, which has little impact on the process time. It solves the problem that the process of the insulation cover is limited, affecting the process time of opening and closing the cover, and the problem that it cannot work due to electrical control failure, and proposes a vehicle-mounted foldable insulation cover device for coke tank.

[0008] As a preferred embodiment of the present invention, the insulation cover body includes two sets of four groups of foldable insulation cover conveying chain assemblies, two sets of four groups of distal sprocket group avoidance devices, two connecting rails attached to the coke tank support beam, four proximal rails, four sprocket gear seat boxes symmetrically arranged at both ends of the coke tank trolley, four groups of gear pairs, four sets of intermittent power transmission mechanisms, two sets of machine bases, two sets of drive devices and their synchronization mechanisms, two sets of accident emergency devices, a centralized lubrication system and a control system.

[0009] As a preferred embodiment of the present invention, the foldable insulation cover consists of an insulation cover trolley and four to five leaf-shaped insulation sheets, which are opened and closed or folded by the conveying chain assembly.

The two sprocket gear seat boxes 5 arranged on the single head of the coke tank trolley are connected to the motor reducer 20 in the middle through two sets of rigid couplings 21. The sprocket gear seat box 5, the motor reducer 20 and the rigid coupling 21 are all connected to the machine base 8 and connected to the machine body through the machine base 8. The middle position of the sprocket gear seat box 5 is rotatably connected to the large gear 22. The sprocket gear seat box 5 is provided with an intermittent power transmission mechanism 7 near the large gear 22. Labyrinth sealing rings 13 are provided on both sides of the rotating coke tank. A short enclosure plate 14 is provided on the outer side of the rotating coke tank near the labyrinth sealing ring 13. A short enclosure plate 2 15 is provided on the outer side of the labyrinth sealing ring 13. A V-shaped wheel 16 is provided at the position corresponding to the connecting rail 4 on the insulation cover trolley 10. A round steel rail 17 is also provided at the position corresponding to the V-shaped wheel 16 on the insulation cover trolley 10. A small gear 19 is provided at one end of the rigid coupling 21. The four connecting rails 4 are respectively connected to the four proximal rails 23.

[0023] Combine Figure 1 and Figure 3 , the conveying chain assembly 2 rotates forward or reversely under the drive of the driving sprocket 9. According to the number of rotations of the driving sprocket 9, the thermal insulation cover presents four states. When the full stroke of 4m is reached after two rotations in the forward direction, the cover is closed and the tank mouth is in a fully sealed state; when the full stroke is reached after two rotations in the reverse direction, the tank mouth is fully opened, and the thermal insulation cover is in a folded, standby or maintenance state, and the remote driven sprocket group avoidance device 3 is in a completely avoided state; when the forward rotation is half a circle and the reverse rotation is one and a half circles, the thermal insulation cover is in a flat state; when the forward rotation is a quarter circle or the reverse rotation is one and three quarters circles, the thermal insulation cover is in a semi-folded state, and the remote driven sprocket group avoidance device 3 is in a horizontal state;

[0024] Combine Figure 1 and Figure 2The foldable insulation cover 1 consists of an insulation cover trolley 10, four to five leaf-type insulation sheets 11, a loose-leaf cover plate 12 and a labyrinth sealing ring 13. The loose-leaf cover plate 12 is arranged along the H-shaped steel lower flange plate of the slightly shorter long side of the insulation cover trolley 10 or the leaf-type insulation sheet 11 and is welded into one. The labyrinth sealing ring 13 is arranged outside the short enclosure plate 14 of the insulation cover trolley 10 and the short enclosure plate 2 15 of the leaf-type insulation sheet 11, and is welded into one with the H-shaped steel lower flange plate. The main beam H-shaped steel is connected to the K-type conveyor chain by a bolt group. The insulation cover trolley 10 is provided with 2 groups, a total of 8 V-shaped wheels 16, which move back and forth on the round steel track 17. The insulation cover trolley 10 and the leaf-type insulation sheet 11 are arranged in sequence through the K-type conveyor chain and form a semicircle on the tank mouth surface. The tank mouth surface is the refractory material insulation layer. The front and rear semicircles face each other during the horizontal transportation of the coke tank. When the two rows are put together, they cover the entire tank mouth to achieve insulation. At the coke receiving position and the hoisting position or the corresponding intermediate transverse trolley parking position, the coke receiving position is located directly below the coke blocking car, and the two semicircles are opposite to each other to make way for the coke tank's upper and lower lifting channels or the horizontal transverse channels to achieve opening and temporary storage of the cover. The foldable insulation cover body 1 is the core and key point of the present invention, which solves two major problems. The foldable leaf-type insulation sheet 11 can be folded along with the conveying chain assembly 2. This feature well digests the problem that the integral half cover will inevitably exceed the outer edge constraint of the length direction of the coke tank trolley when it is opened flat. At the same time, it provides a backward push assist for the remote insulation cover trolley 10, and enables the remote driven sprocket group avoidance device 3 to avoid at a small angle to achieve process requirements. The insulation cover trolley 10 runs smoothly in a high temperature environment with the help of the connecting track, with small structural deformation and the refractory material life can reach more than 1500 heats.

[0025] Combine Figure 1 、 Figure 3 and Figure 4 The foldable thermal insulation device adopts a double-output shaft drive device on one side, namely a motor reducer 20, which connects the driving sprocket 9 and the twin pinion 19 at both ends through a rigid coupling 21. The driving sprocket 9 is responsible for transmitting power to the foldable thermal insulation cover body 1. After the pinion 19 reduces the speed through the large gear 22, it drives the remote driven sprocket group avoidance device 3 to slightly rise by about 7.5 degrees or 12.5 degrees with the help of the intermittent force transmission mechanism 7 in the late folding stage of the leaf-type thermal insulation sheet 11 (linear stroke ≤ 0.5m). The remote driven sprocket group avoidance device 3 is always in a horizontal working state under the action of its own weight for 87.5% of the time. Such a design meets the on-site requirements of "single mechanism, simplified action, easy operation, simple and practical accident plan", which is conducive to the rapid promotion and application of the present invention.

[0026] Combine Figure 2The refractory material of the insulation cover trolley 10 of the foldable insulation cover body 1 is a lightweight high-strength refractory castable with a thickness greater than or equal to 120mm. The skirt of the labyrinth sealing ring 13 is a heat-resistant stainless steel sheet with a thickness greater than or equal to 5mm. The height direction keeps the intersection with the tank mouth greater than or equal to 100mm. The leaf-type insulation sheet 11 of the foldable insulation cover 1 is made of heat-resistant stainless steel enclosure and refractory material on the tank mouth surface. The height of the small trapezoidal section enclosure is the same as the height of the refractory castable. The large trapezoidal section is a labyrinth sealing ring 13 skirt structure. The height direction keeps the intersection with the tank mouth greater than or equal to 100mm. The skirts between the leaf-type insulation sheets 11 are staggered to present a labyrinth sealing state. A loose-leaf cover 12 is added between the leaf-type insulation sheets 11 of the top steel structure and between the leaf-type insulation sheets 11 and the insulation cover trolley 10 to enhance the insulation effect of the insulation cover.

[0027] The coke tank transport vehicles that this device is suitable for include two types: fixed guide frame type coke tank trolley and intermediate trolley type coke tank trolley. Figure 1 A vehicle-mounted coke tank foldable insulation device is suitable for two types of coke tank transport vehicles. Figure 1 The right part is suitable for a coke tank transport vehicle with an intermediate transverse trolley. By slightly raising the driven sprocket group avoidance device 3 at the far end by about 7.5 degrees, it can avoid the high point on the running path of the intermediate transverse trolley. This high point is generally the highest point of the coke tank guide frame. The lever arm of the driven sprocket group avoidance device 3 is a simple pendulum structure with a length of more than 4 meters. An intermittent force-bearing wheel group 18 is provided in the middle. Figure 1 The left part is suitable for a coke tank transport vehicle with fixed upper and lower guide frames. By raising the driven sprocket group avoidance device 3 at the far end by more than 12.5 degrees, it can avoid the coke tank and its supporting beam running channel. Here, a crank connecting rod mechanism is used, with a relatively short rod length of about 2.9m. An intermittent force-bearing wheel group 18 is provided on the crank side.

[0028] On average, one furnace of coke can be produced every 10-15 minutes. The realization of multiple functions by a single drive ensures the reliability of equipment operation. Its application will fill a technological gap and change the history of uncovered coke drums during ground transportation.
