Problems solved by technology

[0004] The technical problem to be solved by the present invention lies in: the internal magnetic rotor of the existing magnetic coupling homogenizer rotates at high speed and generates heat due to friction, the oil temperature in the inner magnetic chamber keeps rising, and the pressure difference inside the homogenizer is small, which cannot make the internal The hot oil in the magnetic cavity and the external cold oil will convect and dissipate heat, which will damage the bearing, greatly shorten the service life of the bearing, and even cause shaft fracture accidents, which will also cause demagnetization of the inner magnetic rotor

Abstract

The invention discloses a heat dissipation structure of a magnetic cavity in a magnetic coupling homogenizer. The heat dissipation structure includes a fluid homogeneous cavity, a homogeneous transmission mechanism and a fluid heat-exchange cavity; the fluid heat-exchange cavity is communicated with the fluid homogeneous cavity to form a heat-exchange fluid inlet channel and a heat-exchange fluidoutlet channel; the homogeneous transmission mechanism includes a main shaft and homogenizer impellers, and the homogenizer impellers are arranged on the main shaft; the terminal end of the main shaftextends into the fluid homogeneous cavity to make the homogenizer impellers limited in the fluid homogeneous cavity; the initiating end of the main shaft is limited in the fluid heat-exchange cavity;the main shaft is of a hollow structure, a feeding hole and a discharging hole are formed in the main shaft, the feeding hole is communicated with the heat-exchange fluid inlet channel, and the discharging hole is communicated with the heat-exchange fluid outlet channel. By making the fluid heat-exchange cavity communicated with the fluid homogeneous cavity, driving force of the homogeneous transmission mechanism enables a cold fluid in the fluid homogeneous cavity to flow into the fluid heat-exchange cavity and a hot fluid in fluid heat-exchange cavity to flow into the fluid homogeneous cavity, and through compulsory convective circulation, the purpose of heat dissipation is achieved.

Description

technical field [0001] The invention relates to the technical field of a magnetic connection homogenizer, and more specifically relates to a heat dissipation structure of a magnetic cavity in a magnetic connection homogenizer. Background technique [0002] At present, a large number of homogenizers are used in the petrochemical and shipbuilding industries. Because the homogenizer can improve the performance of fuel oil, it is more valuable in the field of heavy oil, especially in the secondary cracking of heavy fuel oil. The structure and principle of the existing homogenizers are different, but usually the working mode is driven by the motor to rotate the shaft; due to the user's higher requirements on leakage and the cost control of regular replacement of mechanical seals, the application of the magnetic connection transmission method is more and more More and more widely, therefore, technicians have constructed a transmission mode in which the motor and the homogenizer ar...
