Abstract
Description
Technical Field
[0001] This utility model relates to the field of surface grinding machines, specifically a surface grinding machine used for the production of blast furnace trunnion sleeves. Background Technology
[0002] Surface grinders are a type of grinding machine used to grind flat or shaped surfaces of workpieces. They are widely used for grinding the end faces of parts. The main types of surface grinders include horizontal spindle rectangular table, horizontal spindle rotary table, vertical spindle rectangular table, vertical spindle rotary table, and various special-purpose surface grinders. They mainly use a rotating grinding wheel to grind the workpiece to achieve the required flatness.
[0003] When a surface grinder is working, the friction between the grinding wheel and the machine parts generates a large amount of heat and produces debris. To reduce the temperature of the grinding wheel and machine parts, and to remove debris, coolant is usually sprayed between them. To avoid wasting coolant, surface grinders are typically equipped with a recovery tank containing a filter. This filter filters and recovers the used coolant, allowing it to be recycled. However, because the filter is fixed in place, debris in the coolant is easily trapped on it during filtration. This debris can become stuck in the filter's pores, causing blockage and requiring frequent cleaning, which is inconvenient for operators. Utility Model Content
