TECHNICAL FIELD
[0001] The utility model relates to the field of section steel production technology, specifically to a section steel production fan convenient to install. BACKGROUND
[0002] The production of section steel is a complex and delicate process that involves multiple steps and equipment. During the production process, ventilation is required, which involves several reasons. For example, during the production of section steel, some harmful gases may be produced. If these gases accumulate in the factory building, they may pose a threat to the health of the operators. The ventilation system can effectively remove these harmful gases from the factory building, ensuring production safety. The ventilation system can also help reduce the temperature and humidity in the factory building, reducing the likelihood of fire. Therefore, during the production of section steel, the ventilation system should be designed and used reasonably to ensure the smooth progress of the production process and the health and safety of personnel.
[0003] The patent with the announcement number CN217313900U discloses a section steel production fan convenient to install, which includes a dust mask and a motor. The dust mask is installed on the surface of the front ring by inserting into the nesting groove. The nesting groove has an electricity connection ring installed at the bottom. The front ring and the back ring are clamped at both ends of the machine shell. The motor is installed inside the machine shell. The motor is connected to the blade through the hub. The motor is installed at the bottom of the machine shell through the support. The machine shell has a power supply assembly electrically connected to the motor. The inner wall of the front ring has an electrostatic generator electrically connected to the electricity connection ring. The machine shell has an inclined support installed at the bottom. This section steel production fan convenient to install can be used after being placed and does not require professional tools and workers for installation, which is low in labor cost and has the advantages of convenient installation, simple operation, good stability, good dust removal effect, and convenient cleaning.
