The utility model provides a hot filtering funnel of electrical heating for the teaching and the scientific research instrument of hot filter operation are carried out to the laboratory, belong to the teaching and research field of chemistry, chemical industry and environmental science specialty. Use the electricity as the heat source, heating temperature is both controllable, can adjust at will again. The utility model provides a hot filtering funnel comprises funnel, funnel support and heating temperature control system, has safe in utilization, convenient advantage. The funnel process out the funnel shape on heat -transferring medium container or the metal block as heat -transferring medium, funnel support be prop processing have the funnel shape the heat -transferring medium container or as the corrosion resistant plate of heat -transferring medium's metal block, heating temperature control system constitute by electrical heating rod, thermocouple, temperature control instrument and switch. Make the funnel keep the uniform temperature through the electrical heating to reach the filterable mesh of heat. Use the hot filtering funnel of this kind, can realize hot filter operation under no coal gas condition, and easy and simple to handle, safety.
