Multifunctional slurry pressurizing tank

The utility model discloses a multifunctional slurry pressurizing tank which comprises a PPR tank body, an upper end sealing plate, a lower end sealing plate, a threaded pull rod, an O-shaped sealing ring and the like. The material and the overall structure of an original metal mud pressurizing tank are changed, the PPR material which can resist pressure of 1.6 MPa and has the wall thickness of 15 mm is adopted as the tank body of the mud pressurizing tank, the inner wall of the PPR tank body is smooth, mud is not suitable for being bonded with the tank body, the phenomenon that the mud is hung on the wall of the mud pressurizing tank is reduced, and the service life of the mud pressurizing tank is prolonged. The pressurization tank body made of the PPR material can solve the problems that a non-contact capacitance liquid level detection sensor is installed outside the tank body, the thermal conductivity of the PPR material is one twentieth of the thermal conductivity of metal, the thermal conductivity of the
