Description
Technical Field
[0001] This utility model relates to the technical field of gasifier lining construction, and in particular to a construction device for installing water-cooled wall gasifier lining. Background Technology
[0002] In modern coal chemical and energy conversion industries, water-cooled wall gasifiers serve as core reaction equipment. Their operating environment is characterized by high temperature, high pressure, and frequent scouring by corrosive gases. The refractory lining of the furnace inner wall, as a critical protective structure, directly determines the gasifier's service life and operational safety. This lining is typically formed by mixing high-alumina and corundum refractory materials with a binder in a specific ratio and then casting it. The quality of its construction has a decisive impact on the lining's density, uniformity, and anti-stripping performance. Therefore, the mixing, preparation, and precise delivery of the lining material are key control points in the construction process. Currently, in the installation and construction of water-cooled wall gasifier linings, the handling of lining materials largely relies on decentralized equipment, resulting in low raw material conveying efficiency and poor proportioning accuracy during the feeding process. In existing technologies, the main raw materials are mostly manually transported to the feeding port above the mixing tank for feeding. This is not only labor-intensive and inefficient, but also prone to deviations in the raw material mixing ratio due to uneven feeding speeds. Some feeding equipment using screw conveyors has fixed conveying pipes, making it impossible to adjust the conveying angle and height according to the position of the mixing tank. After the mixing tank is positioned, the discharge pipe position needs to be manually adjusted to align with the feeding port, which is cumbersome and prone to raw material spillage, leading to material waste.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0016] Reference Figures 1-4 This embodiment provides a construction device for installing the lining of a water-cooled wall gasifier, comprising: Support plate 1 is set on the ground and has a notch; The mixing tank 11 is movable and set on the ground. When mixing, the mixing tank 11 is placed at the notch of the support plate 1. The stirring support column 12 is fixedly installed on the support plate 1; The stirring mechanism 2 is mounted on the stirring support column 12 and moves up and down to stir the lining material inside the stirring tank 11. The feeding mechanism 3 is mounted on the support plate 1 and is used to transport the main raw materials; Among them, the feeding mechanism 3 includes: The feeding bracket 31 is fixedly installed on the support plate 1; The hoisting plate 32 is fixedly installed on the top of the feeding bracket 31; The conveying pipe 33 has a conveying chamber inside. A feeding pipe 34 is connected to the conveying pipe 33. The feeding pipe 34 is rotatably mounted on the lifting plate 32. A discharge pipe 36 is connected to the output end of the conveying pipe 33. The output end of the discharge pipe 36 is connected to the stirring mechanism 2. The conveying blade 35 is rotatably disposed inside the conveying pipe 33 and is driven by a motor. In this embodiment, the stirring mechanism 2 is controlled to move downward along the stirring support column 12 until the stirring cover of the stirring mechanism is tightly closed on the top of the stirring tank 11; the operator adds the main raw materials into the conveying chamber of the conveying pipe 33 through the feeding pipe 34 of the feeding mechanism 3; the drive motor of the conveying blade 35 is started, and the motor drives the conveying blade 35 to rotate at high speed in the conveying pipe 33, using the spiral thrust of the blade to stably push the raw materials along the conveying chamber to the output end of the conveying pipe 33; the raw materials are discharged through the discharge pipe 36 connected to the output end of the conveying pipe 33 and directly conveyed to the feeding part of the stirring mechanism 2, and then the stirring mechanism 2 guides the raw materials into the stirring tank 11 below, completing the automated feeding process; the stirring blade drive motor of the stirring mechanism is started, driving the stirring blade to rotate in the stirring tank 11 to uniformly stir the lining material; after the stirring operation is completed, the stirring mechanism 2 is controlled to move upward along the stirring support column 12 to reset, and then through the rotational cooperation of the feeding pipe 34 and the lifting plate 32, the conveying pipe 33 is driven to swing as a whole, adjusting the conveying pipe 33 and the discharge pipe 36 to deviate from the stirring mechanism 2. The main body is positioned to avoid interference between components during subsequent movement of the mixing tank 11 or operation of the mixing mechanism. Finally, the mixing tank 11, after mixing the lining material, is moved out from the notch of the support plate 1 for subsequent pouring operations. An automated feeding system is formed by the motor-driven conveying blades 35 and the conveying pipe 33. There is no need for manual handling of raw materials. The raw materials can be continuously and stably conveyed by simply adding them through the feeding pipe 34, which reduces the labor intensity of construction personnel and reduces labor costs. The uniform rotation of the conveying blades 35 can accurately control the raw material conveying rate, avoid the imbalance of the proportion caused by manual feeding, and ensure that the ratio of refractory material and binder in the lining material meets the construction requirements, thereby improving the density and uniformity of the lining. The feeding pipe 34 is rotatably installed on the lifting plate 32, which can drive the conveying pipe 33 to swing as a whole. When not in use, it can swing to avoid the mixing mechanism 2 to prevent damage from collisions. It can also finely adjust the angle of the conveying pipe according to the position of the mixing tank 11 or the mixing mechanism 2 to ensure that the discharge pipe 36 is accurately connected to the feed inlet of the mixing mechanism, thereby improving the flexibility of equipment operation and the safety of operation.
[0017] As a preferred embodiment of the above technical solution, such as Figure 2 As shown, the feeding mechanism 3 also includes: The support rail 37 is fixedly installed on the support plate 1; A support column 38 is fixedly installed on the outer wall of the conveying pipe 33. A support guide wheel 39 is provided at the bottom of the support column 38. The support guide wheel 39 is rolled on the support guide rail 37. In this embodiment, the conveying pipe 33 is connected to the support rail 37 on the support plate 1 by the support column 38 and the support guide wheel 39. When the raw material is conveyed, this structure can effectively counteract the radial displacement of the conveying pipe 33 caused by vibration, prevent the conveying pipe from tilting and causing the discharge pipe 36 to deviate from the feed inlet of the mixing mechanism 2, improve the material utilization rate and avoid material waste. The support guide wheel 39 and the support rail 37 adopt a rolling fit, which converts the sliding friction when the conveying pipe swings into rolling friction. The operator only needs to apply a small pushing force to drive the conveying pipe 33 to swing as a whole, reducing the operation intensity.
[0018] Specifically, such as Figure 2 As shown, a feeding hopper 3a is connected to the feeding pipe 34; In this embodiment, the funnel-shaped structure of the feeding hopper 3a increases the material receiving area. Operators do not need to accurately align the material with the small end of the feeding pipe 34; they only need to pour the material into the feeding hopper, making the feeding action easier. At the same time, the cavity of the feeding hopper can temporarily store the material, avoiding operators from frequently going back and forth to retrieve the material, reducing repetitive work, and significantly reducing labor intensity.
[0019] More specifically, such as Figures 3 to 4 As shown, the stirring mechanism 2 includes: The lifting bracket 21 is slidably mounted on the stirring support column 12. The mixing cover 22 is fixedly installed on the lifting bracket 21. When the mixing cover 22 slides down to the lowest point, it is installed on the mixing tank 11. The mixing cover 22 is connected to the material receiving port 24, which is used to receive the raw materials discharged from the discharge pipe 36. The stirring blade 23 is rotatably positioned below the stirring cover 22, and the stirring blade 23 is driven to rotate by a motor. In this embodiment, after the feeding process is started, the raw materials conveyed by the feeding mechanism 3 are discharged through the discharge pipe 36 and fall directly into the receiving port 24 of the mixing cover 22. The receiving port 24 is connected to the inside of the mixing cover 22, and the raw materials smoothly enter the mixing tank 11 below through the receiving port, avoiding spillage of the raw materials during the conveying process. After all the raw materials are conveyed to the mixing tank 11 according to the ratio, the drive motor of the stirring blade 23 is started, and the motor drives the stirring blade 23 to rotate at high speed below the mixing cover 22. The blade structure of the stirring blade 23 produces a shearing, tumbling and mixing effect on the lining material in the mixing tank 11, so that the raw materials are fully integrated and a uniform lining slurry is formed. During the stirring process, the lifting support 21 remains stable to ensure that the material is in good condition. The mixing cover 22 is always tightly closed on the mixing drum 11 to prevent material splashing or gas leakage. The mixing cover 22 is precisely lowered by the lifting bracket 21 to ensure a tight seal between the mixing cover and the mixing drum 11, forming a closed mixing space. This prevents the lining material from splashing out of the drum due to centrifugal force when the mixing blades 23 rotate, reducing material waste. The closed structure effectively blocks dust generated during the mixing process, preventing it from spreading to the working environment. It also prevents external impurities from falling into the mixing drum and contaminating the lining material, ensuring the purity of the lining material. The lifting bracket 21 can slide up and down along the mixing support column 12. By adjusting the position of the lifting bracket, it can be adapted to mixing drums 11 of different heights without replacing the main body of the mixing mechanism.
[0020] Furthermore, such as Figure 4 As shown, multiple guide wheels 25 are rotatably arranged on the lifting bracket 21, and each guide wheel 25 is rolled and attached to the stirring support column 12. A threaded slider 26 is provided in the lifting bracket 21, and the threaded slider 26 is slidably arranged in the stirring support column 12. A lifting screw 27 is vertically rotatably arranged inside the stirring support column 12, and the lifting screw 27 is threadedly inserted into the threaded slider 26. In this embodiment, when the stirring cover 22 needs to be placed on the stirring tank 11, the drive motor of the lifting screw 27 is started. The motor drives the lifting screw 27 to rotate clockwise inside the stirring support column 12. Since the lifting screw 27 is threadedly engaged with the threaded slider 26, and the threaded slider 26 is fixedly connected to the lifting bracket 21 and cannot rotate synchronously with the screw, the rotational motion of the lifting screw is converted into the linear motion of the threaded slider 26 vertically downward along the stirring support column 12, thereby driving the lifting bracket 21 to move downward synchronously. During this process, the multiple guide wheels 25 on the lifting bracket 21 roll along the outer wall of the stirring support column 12, providing circumferential guidance for the lifting bracket: preventing the lifting bracket from tilting due to gravity or thread transmission clearance, ensuring that the lifting bracket always moves in the vertical direction; and reducing the resistance when the lifting bracket moves downward by replacing sliding friction with rolling friction, thus avoiding wear between the bracket and the support column. When the bottom of the mixing cover 22 is in contact with the top of the mixing tank 11, the drive motor is turned off, the lifting screw 27 stops rotating, and the threaded slider 26 and the lifting bracket 21 remain in their current positions, completing the sealing of the mixing cover. After the mixing operation is completed, the mixing cover 22 needs to be lifted and reset. At this time, the drive motor of the lifting screw 27 is started to reverse, causing the lifting screw 27 to rotate counterclockwise. Similarly, the threaded slider 26 moves vertically upward along the mixing support column 12 under the action of threaded transmission, causing the lifting bracket 21 to move upward synchronously. The guide wheel 25 on the lifting bracket rolls along the outer wall of the mixing support column 12 again, continuously providing guidance and drag reduction for the upward movement, preventing the lifting bracket from swaying due to inertia when it moves upward. When the lifting bracket 21 rises back to the initial high position, the drive motor is turned off, the lifting screw 27 stops rotating, and the threaded slider 26 and the lifting bracket 21 remain stably in the high position, waiting for the next operation.
[0021] Furthermore, such as Figure 4 As shown, a positioning bracket 28 is provided on the stirring support column 12, and two positioning plates 29 are symmetrically arranged on the positioning bracket 28 for positioning the stirring tank 11. In this embodiment, when it is necessary to move the mixing tank 11 to the notch of the support plate 1, the operator manually pushes or uses auxiliary handling equipment to move the mixing tank along the ground towards the notch. As the mixing tank approaches the mixing support column 12, it first contacts the two symmetrical positioning plates 29 on the positioning bracket 28. Due to the symmetrical arrangement of the positioning plates 29, the mixing tank gradually moves towards the middle area of the two plates under the action of the moving thrust. The two positioning plates limit the lateral displacement of the mixing tank, preventing the mixing tank from deviating from the preset path during the movement, and guiding the mixing tank to move precisely towards the notch of the support plate 1. As the mixing tank 11 continues to move... When the middle part of the barrel is fully inserted into the area between the two positioning plates 29, the inner wall of the positioning plate is tightly fitted with the outer wall of the mixing barrel. At this time, the mixing barrel is completely limited in the lateral direction and cannot shift left or right. At the same time, under the guidance and limiting effect of the positioning plate, the center of the barrel opening is completely aligned with the center of the mixing cover 22 of the upper mixing mechanism 2 and the center of the notch of the support plate 1. The mixing barrel is accurately placed at the notch of the support plate 1, completing the positioning. In the subsequent feeding and mixing process, the positioning plate 29 always remains in contact with the outer wall of the mixing barrel to counteract the radial impact force generated on the mixing barrel when the mixing blade 23 rotates, preventing the mixing barrel from shifting.
[0022] Furthermore, a protective pad is provided on the end face of the positioning plate 29; In this embodiment, the protective pad, through its elastic buffering and isolation function, ensures that the mixing tank 11 and the positioning plate 29 always maintain flexible contact, preventing physical damage such as scratches and dents on the outer wall of the mixing tank, effectively protecting its surface anti-rust layer, and extending the service life of the mixing tank. The elastic material of the protective pad can effectively absorb collision energy and vibration, improve the noise environment at the construction site, and enhance the working comfort of the operators.
[0023] Furthermore, such as Figure 3 As shown, an exhaust valve 2a is connected to the stirring cover 22; In this embodiment, the exhaust valve 2a can discharge the gas generated during the stirring process in real time, control the pressure inside the stirring tank 11 within a slightly positive pressure range, prevent excessive pressure from opening the sealing surface between the stirring cover 22 and the stirring tank, avoid the lining material slurry from splashing out of the tank from the sealing gap, and reduce material waste.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
