Description

Technical Field

[0001] This utility model relates to the field of filtration equipment, specifically to a novel filtration device. Background Technology

[0002] Filtration equipment is primarily used for solid-liquid separation of materials during or after a reaction. It typically consists of built-in or external filter components and is suitable for processes such as crystallization, catalysis, and extraction in industries like pharmaceuticals, chemicals, and food. This equipment enables closed-loop operation, reducing material transfer and contamination, improving production efficiency and product purity. It also features high-temperature resistance, corrosion resistance, and easy cleaning, and its filtration precision and automation level can be customized to meet specific process requirements.

[0003] Chinese patent CN222489395U discloses a reactor filtration device, including an outer shell. The outer shell is cylindrical, with a waste gas inlet at the bottom, a waste gas outlet at the left end, a quick-opening door at the far right, and an observation quick-opening door at the top. Inside the cylinder is an inner liner, which is located within the outer shell. The inner liner is filled with saddle-shaped ceramics, which are used for heat storage to maintain the temperature inside the liner. This device can perform solid-gas separation and maximize the separation of carbon powder from the waste gas emitted from the reactor, reducing condensation and at least solving the problem of tar solidification clogging the pipes. However, this device still has the following problems:
