[0002] Biomass gasification technology is one of the important ways to utilize biomass energy. It converts biomass into combustible gas through high-temperature thermochemical reactions, which can be used in multiple fields such as power generation, heating, and fuel synthesis. The biomass gasifier, as the core equipment of biomass gasification technology, directly affects gasification efficiency and gas quality. During the operation of the biomass gasifier, the furnace experiences high temperature, high pressure, and complex chemical reaction environments. To protect the outer shell of the gasifier from high-temperature damage and ensure the stable operation of the gasification process, a high-temperature resistant working lining is usually installed inside the gasifier.
[0003] Traditional processes for splicing and fixing high-temperature working linings in biomass gasifiers are cumbersome and require extensive manual labor. From lining handling, positioning, and fixing to welding, each step consumes significant time and manpower. Traditional welding equipment and processes severely hinder project progress when welding high-temperature working linings for biomass gasifiers. Furthermore, in high-temperature environments, traditional welding equipment easily generates large amounts of harmful fumes, which not only seriously endanger the health of operators but also pollute the surrounding environment.

[0006] Furthermore, dustproof rubber sleeves are provided on both sides of the adjusting block. The outer end of the dustproof rubber sleeve is fixedly connected to the inner wall of the adjusting box, and the upper and lower ends of the dustproof rubber sleeve are slidably engaged with the adjusting box.
[0007] Furthermore, four omnidirectional casters are provided at the bottom of the base.
[0008] Furthermore, the lifting assembly includes: The lifting screw is vertically rotatably mounted on the load-bearing column, and the lifting screw is driven to rotate by a motor.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] See Figure 1-5 As shown; This utility model provides a high-temperature resistant working lining splicing and fixing device for a biomass gasifier, comprising: Base 1, which is supported and set on the ground; A load-bearing column 11 is fixedly installed on the base 1, and a lifting component is provided on the load-bearing column 11. The lifting plate 12 is slidably mounted on the load-bearing column 11, and its height is controlled by the lifting assembly. The lifting plate 12 is equipped with a horizontal adjustment assembly. The horizontal support arm 13 is horizontally slidably mounted on the lifting plate 12 and its translation is controlled by the horizontal adjustment component. Welding assembly 2, located at the end of the cross arm 13, is used for welding the lining; Welding component 2 includes: The adjusting box 21 is fixedly connected to the horizontal support arm 13, and the adjusting box 21 is provided with a transmission slide cavity; The adjusting screw 22 is rotatably mounted inside the adjusting box 21 and is driven by a motor. The adjusting block 23 is horizontally slidably disposed in the transmission slide cavity inside the adjusting box 21. The adjusting block 23 is threadedly engaged with the adjusting screw 22, and the sliding is controlled by the adjusting block 23. The welding hanger 24 is fixedly connected to the outer end face of the adjusting block 23; Welding torch 25, mounted on welding hanger 24, is used for welding the lining; By adopting the above technical solution, the base 1 is supported on the ground, providing a stable support foundation for the entire device and ensuring that the device will not shake or shift during operation. The load-bearing column 11 is fixedly installed on the base 1, and the lifting assembly on it can control the height of the lifting plate 12. According to the approximate height position of the biomass gasification furnace lining, the lifting assembly is operated to make the lifting plate 12 slide up and down on the load-bearing column 11, adjusting the device to a suitable height range. A horizontal adjustment assembly is provided on the lifting plate 12, and the horizontal support arm 13 is horizontally slidably mounted on the lifting plate 12. According to the horizontal position of the lining, the horizontal adjustment assembly is operated to control the horizontal support arm 13 to move horizontally on the lifting plate 12, so that the welding... The welding assembly 2 is approximately located near the lining to be welded; the welding assembly 2 is positioned at the end of the horizontal support arm 13, wherein the adjusting box 21 is fixedly connected to the horizontal support arm 13; the adjusting block 23 is horizontally slidably disposed within the transmission slide cavity inside the adjusting box 21 and is threadedly engaged with the adjusting screw 22; when more precise lateral adjustments are required based on the specific welding position of the lining, the motor is started to drive the adjusting screw 22 to rotate; since the adjusting block 23 is threadedly engaged with the adjusting screw 22 and can only slide horizontally due to the limitation of the transmission slide cavity, the rotation of the adjusting screw 22 will cause the adjusting block 23 to slide horizontally, thereby driving the welding hanger 24 fixedly connected to the outer end face of the adjusting block 23 and the welding torch 25 disposed on the welding hanger 24 to move together, thus achieving... The welding torch 25 is precisely positioned laterally to accurately align with the area of the lining to be welded. Once the welding torch 25 is accurately aligned with the welding area, it can be activated to perform welding operations on the lining, completing the splicing and fixing of the lining. The device provides stable support through the base 1 and utilizes the lifting components on the load-bearing column 11, the horizontal adjustment components on the lifting plate 12, and the adjusting screws 22 and adjusting blocks 23 within the welding assembly 2 to achieve automatic adjustment in multiple directions, including height, horizontality, and lateral movement. This reduces manual handling, positioning, and fixing operations, greatly simplifying the operation process and lowering labor costs. The base 1, load-bearing column 11, lifting plate 12, and horizontal support arm 13 work together... The system can quickly adjust the welding component 2 to its approximate position, and then precisely adjust the position of the welding torch 25 by adjusting the screw 22 and the adjusting block 23, quickly adjusting the welding torch 25 to the appropriate position, shortening the preparation time before welding and the welding process time, thereby improving the overall work efficiency and accelerating the project construction progress. Through precise mechanical adjustment and automated operation, the base 1 provides stable support, the load-bearing column 11, the lifting plate 12, the horizontal support arm 13 and the various components of the welding component 2 cooperate with each other. Compared with traditional equipment, since automated welding does not require the operator to hold the welding torch at close range, the operator can complete the operation through the control system from a position away from the welding area, which greatly reduces the risk of direct contact with harmful fumes to the human body.
[0018] As a preferred embodiment of the above technical solution, such as Figure 3As shown, dustproof rubber sleeves 26 are provided on both sides of the adjusting block 23. The outer end of the dustproof rubber sleeve 26 is fixedly connected to the inner side wall of the adjusting box 21, and the upper and lower ends of the dustproof rubber sleeve 26 are slidably engaged with the adjusting box 21. In this embodiment, during the movement of the adjusting block 23, the dustproof rubber sleeve 26, due to its sliding fit with the adjusting box 21 at both ends, can undergo corresponding expansion and contraction deformation as the adjusting block 23 moves, always maintaining a tight fit with both sides of the adjusting block 23, continuously playing a dustproof role, and ensuring that the transmission slide cavity inside the adjusting box 21 is always in a relatively clean environment; the setting of the dustproof rubber sleeve 26 can effectively block dust and impurities from entering the transmission slide cavity, reduce the wear of components, extend the service life of components such as the adjusting screw 22 and the adjusting block 23, and reduce the maintenance cost of the equipment.
[0019] As a preferred embodiment of the above technical solution, such as Figure 1 As shown, four omnidirectional casters are provided at the bottom of the base 1; In this embodiment, the four omnidirectional casters at the bottom of the base 1 enable the device to move easily between various work areas without the need for complex disassembly and reinstallation, improving the device's mobility and flexibility. This allows it to quickly adapt to different work scenarios and reduce work delays caused by difficulties in moving the equipment. With the omnidirectional casters, the device can be easily moved by a single operator, saving labor costs. At the same time, the movement process is quick and easy, reducing the time spent moving the equipment and improving overall work efficiency.
[0020] As a preferred embodiment of the above technical solution, such as Figure 4 As shown, the lifting assembly includes: The lifting screw 31 is vertically rotatably mounted on the load-bearing column 11, and the lifting screw 31 is driven to rotate by a motor. Two lifting slide rails 32 are symmetrically arranged on the load-bearing column 11; Two guide slides 33 are fixedly installed on the lifting plate 12. Each guide slide 33 is provided with two first sliders 34. The two first sliders 34 on the same guide slide 33 are slidably locked onto the same lifting slide rail 32. The transmission screw sleeve 35 is threadedly fitted onto the lifting screw 31, and the transmission screw sleeve 35 is fixedly connected to the lifting plate 12. In this embodiment, when the height of the lifting plate 12 needs to be adjusted to accommodate the splicing, fixing, and welding operations of the high-temperature resistant working lining of the biomass gasifier at different positions, the operator starts the motor driving the lifting screw 31; the motor starts running and drives the lifting screw 31 to rotate on the load-bearing column 11; the transmission sleeve 35 is threaded onto the lifting screw 31, and according to the principle of threaded transmission, when the lifting screw 31 rotates, the transmission sleeve 35 will move linearly along the axis of the lifting screw 31; the transmission sleeve 35 is fixedly connected to the lifting plate 12, and the linear movement of the transmission sleeve 35 will drive the lifting plate 12 to move together; at the same time, two guide plates 33 are fixedly installed on the lifting plate 12, and the two first sliders 34 on each guide plate 33 are slidably engaged on the same lifting slide rail 32; During the lifting process of the lifting plate 12, the first slider 34 slides along the lifting rail 32, providing guidance for the movement of the lifting plate 12 and ensuring that the lifting plate 12 can only move smoothly in the vertical direction without any horizontal deviation or swaying. When the lifting plate 12 moves to the required height position, the operator stops the motor. At this time, the lifting plate 12 stops lifting and remains at the current height. The threaded transmission method of the lifting screw 31 and the transmission sleeve 35 can achieve precise adjustment of the height of the lifting plate 12. By controlling the running time and rotation direction of the motor, the lifting plate 12 can be precisely adjusted to the required height position, thereby meeting the splicing, fixing and welding requirements of the high-temperature working lining of biomass gasification furnaces of different specifications and positions, and improving the accuracy and quality of the work.
[0021] As a preferred embodiment of the above technical solution, such as Figure 5 As shown, the horizontal adjustment component includes: Four second sliders 41 are fixedly installed on the front end face of the lifting plate 12; A drive gear 42 is rotatably mounted on a drive gear 42, and the drive gear 42 is driven to rotate by a motor. Two horizontal slide rails 43 are symmetrically installed on the horizontal support arm 13, and the horizontal slide rails 43 are in sliding engagement with the second slider 41. Rack 44 is fixedly mounted on cross arm 13, and rack 44 meshes with drive gear 42; In this embodiment, when the horizontal support arm 13 needs to be adjusted horizontally, the motor driving the drive gear 42 is started; the motor starts running and drives the drive gear 42 to rotate; since the rack 44 meshes with the drive gear 42, according to the principle of rack and pinion transmission, when the drive gear 42 rotates, it will drive the rack 44 to move linearly; the movement of the rack 44 will directly drive the horizontal support arm 13 to move horizontally in a linear motion; during the horizontal movement of the horizontal support arm 13, four second sliders 41 are fixedly installed on the front end face of the lifting plate 12, and two horizontal slide rails 43 are symmetrically installed on the horizontal support arm 13, and the horizontal slide rails 43 slide in cooperation with the second sliders 41; the second sliders 41 slide along the horizontal slide rails 43, providing guidance for the horizontal movement of the horizontal support arm 13, ensuring the horizontal support arm The horizontal support arm 13 can only move smoothly in a straight line in the horizontal direction without any vertical deviation or swaying, ensuring the stability and accuracy of the movement. When the horizontal support arm 13 moves to the desired target position so that the welding assembly 2 can be aligned with the lining part to be welded, the operator stops the motor. At this time, the horizontal support arm 13 stops moving horizontally and remains in the current position for subsequent welding operations. The use of a gear and rack transmission method enables precise adjustment of the horizontal position of the horizontal support arm 13. By controlling the motor's running time and rotation direction, the rotation angle of the drive gear 42 is precisely controlled, thereby precisely controlling the horizontal movement distance of the rack 44 and the horizontal support arm 13, so that the welding assembly 2 can accurately reach the lining position to be welded, improving the welding accuracy and quality.
[0022] As a preferred embodiment of the above technical solution, such as Figure 5 As shown, each horizontal slide rail 43 has two limit blocks 45 at both ends; In this embodiment, the limiting block 45 effectively restricts the movement range of the horizontal support arm 13, avoids collision accidents, and ensures the safe operation of the equipment; the limiting block 45 can prevent the horizontal support arm 13 from moving excessively and falling off, thereby improving the stability and reliability of the equipment.
[0023] As a preferred embodiment of the above technical solution, the horizontal slide rail 43 and the rack 44 are parallel to each other; In this embodiment, the horizontal slide rail 43 and the rack 44 are parallel to each other, so that the horizontal support arm 13 can move strictly along a straight trajectory during horizontal movement; this can prevent the horizontal support arm 13 from deviating during movement, thereby ensuring that the welding assembly 2 can accurately reach the part that needs to be welded, and improving the accuracy and quality of welding.
[0024] As a preferred embodiment of the above technical solution, a counterweight is provided inside the base 1; In this embodiment, during the movement and operation of the device, since the upper part of the device has components such as the lifting plate 12, the horizontal support arm 13 and the welding assembly 2, its center of gravity is relatively high. The counterweight block set in the base 1 can lower the overall center of gravity of the device. The lower the center of gravity, the more stable the object is, thereby effectively preventing the device from tipping over due to the high center of gravity during operation, ensuring the personal safety of the operator and the normal operation of the device.
[0025] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
