Description

Technical Field

[0001] This utility model relates to the technical field of gasifier accessories, specifically a gasifier nozzle preparation fixture device. Background Technology

[0002] Straw gas produced by biomass gasification furnaces is a green new energy source with strong vitality. Because the raw materials for plant-based gas production are crop straw, forest waste, edible mushroom residue, livestock manure, and all combustible materials, it is an inexhaustible renewable resource. However, in my country's current rural energy structure, straw gas is the most economical, convenient, energy-efficient, and applicable, not only safe to use but also clean and hygienic. Each farmer only needs 3-5 kg ​​of plant material per day to solve their daily energy needs, and it burns like liquefied petroleum gas (LPG), completely changing the smoky lifestyle in rural my country and potentially replacing traditional wood-burning stoves with LPG.

[0003] In the assembly and manufacturing of biomass gasifiers, it is necessary to test or inspect the prepared semi-finished or finished components, such as the gasifier nozzle, to ensure the quality of the gasifier products. This requires the use of a gasifier nozzle fixing structure to position the gasifier nozzle to be tested or inspected. However, the existing fixture devices have low flexibility and are not convenient to adjust according to the size of the gasifier nozzle, resulting in low applicability. Therefore, a gasifier nozzle preparation fixture device is proposed to solve the above-mentioned problems. Utility Model Content

The rotation of the bidirectional screw 202 can adjust the distance between the first moving seat 201 and the second moving seat 213, thus facilitating the adjustment of the gasifier nozzle length. After the position is adjusted, the gasifier nozzle is placed between the lower clamp 206 and the upper clamp 210. The handle 208 is rotated to rotate the threaded rod 207, causing the pressure block 209 to move down so that the upper clamp 206 and the lower clamp 210 clamp and fix it. This is suitable for fixing gasifier nozzles of different lengths, improving the flexibility of the clamping device.

[0026] The bidirectional screw 202 is rotatably connected to the inside of the movable port 4 via a bearing. A rotating wheel 204 is fixedly connected to the bidirectional screw 202.

[0029] Working principle: Based on the length of the gasifier nozzle, the operator rotates the rotating wheel 204 to rotate the bidirectional screw 202. The rotation of the bidirectional screw 202 can adjust the distance between the first moving seat 201 and the second moving seat 213, thus facilitating the adjustment of the gasifier nozzle length. After the position is adjusted, the gasifier nozzle is placed between the lower clamp 206 and the upper clamp 210. The handle 208 is rotated to rotate the threaded rod 207, causing the pressure block 209 to move down, so that the upper clamp 206 and the lower clamp 210 clamp and fix it. This is suitable for fixing gasifier nozzles of different lengths, improving the flexibility of the clamping device.
