[0002] o-Fluorotoluene, also known as 2-fluorotoluene, is an important raw material of organic fluorine compounds. Its English name is 2-Fluorotoluene or o-Fluorotoluene. Its molecular formula is C7H7F, its molecular weight is 110.3, and its CAS number is 95-52-3. o-Fluorotoluene is a transparent, colorless to slightly yellow liquid at room temperature, with a specific melting point and boiling point. Its storage conditions are usually below 30°C, and it is mainly used in organic synthesis, especially as an intermediate for medicines and pesticides. Due to its unique chemical properties, feeding equipment is required during the production process, but the existing o-fluorotoluene feeding equipment has some shortcomings, such as:

After the filter screen has been used for a long time, the T-bar is rotated to drive the stopper to squeeze the movable block, and the movable block compresses the spring and gradually enters the square groove from the movable groove. When the movable block completely enters the square groove, the plug block can be pulled out of the connecting block, that is, the filter screen is disassembled.
