Description

Technical Field

[0001] This application relates to the field of nitrous oxide production technology, specifically to a self-cleaning pipeline for nitrous oxide production. Background Technology

[0002] Nitrous oxide, also known as laughing gas, is an important industrial gas primarily used in the medical and electronics industries, traditionally as an anesthetic. In recent years, with the development of modern industry, the application of high-purity nitrous oxide in the electronics industry has become increasingly widespread, especially as a crucial material for semiconductor technology development, primarily used in integrated circuits, liquid crystal displays, and other technological fields, and its development trend is rapid.

[0003] Patent CN217887883U discloses a continuous feeding device for the production of high-purity nitrous oxide. This device uses a drive unit composed of a first drive shaft, a first gear, a second drive shaft, a second gear, a half gear, and a third gear to control the intermittent rotation of a spiral blade. After the raw material is poured into the mixing tank, the rotating stirring shaft mixes and disperses the material. Then, the half gear meshes with the third gear, driving the spiral blade to feed the dispersed material into the production equipment. This prevents the raw material from condensing and affecting product quality. However, this device cannot promptly clean the material adhering to the inner wall of the discharge pipe, which will affect the correct ratio of subsequent raw materials and reduce the quality of the subsequent nitrous oxide. Therefore, the inner wall of the pipe needs to be cleaned after each use, reducing the production efficiency of nitrous oxide. Utility Model Content

[0023] (III) Beneficial Effects

[0024] This application provides a self-cleaning pipeline for nitrous oxide production. It has the following beneficial effects:

[0025] 1. This self-cleaning pipeline for nitrous oxide production removes blockages from the discharge pipe through a discharge mechanism. The output shaft of the second motor in the fixed box connected to the fixed rod rotates, driving the connecting rod to rotate. The rotation of the connecting rod drives the cleaning plate to rotate, which in turn discharges the raw material from the discharge pipe. This facilitates continuous use of the nitrous oxide production equipment and ensures the accuracy of the raw material ratio, thereby guaranteeing the quality of nitrous oxide, improving the production efficiency of nitrous oxide, and reducing cleaning costs.

[0026] 2. This self-cleaning pipeline for nitrous oxide production features an adjustment mechanism. The electric actuator hinged to the support rod shortens, causing the drive rod to rotate. This rotation of the drive rod, in turn, causes the mixing tank on one side of the connecting block to rotate, adjusting the feed pipe to its lowest position. This reduces the possibility of insufficiently mixed raw materials entering the discharge pipe, ensuring smooth mixing and guaranteeing the accuracy of the raw material ratio.

The rotation of the rotating rod 306 drives the mixing plate 307 to rotate, thoroughly mixing the raw materials. The vibration generated during the mixing of nitrous oxide raw materials is transmitted downwards and is reduced by the damping column 202 and the spring 204 between the fixed plate 201 and the connecting plate 203. After mixing is completed, the electric push rod 402, which is hinged to the support rod 401, shortens, driving the driving rod 403 to rotate. The rotation of the mixing tank 301 on one side of the connecting block 404 causes the mixing tank 301, which has a groove 302 that is rotatably connected to the fixing ring 303, to rotate. The rotation of the mixing tank 301 causes the discharge pipe 501 to be adjusted to the lowest point, removing the block 502 in the discharge pipe 501.
