A tank washing machine with magnetic drive

Abstract

The invention discloses a magnetic transmission tank washing machine which comprises a gearbox, a power control box and a machine body, wherein the gearbox, the power control box and the machine body are sequentially connected from top to bottom. The power control box comprises a power control box body, a power control box cavity and a power control box water inlet cavity are formed in the power control box body, the power control box cavity and the power control box water inlet cavity are communicated with each other, a water inlet is formed in the power control box cavity, a rotary wheel axle is arranged in the power control box cavity, and a rotary wheel and a magnetic disk are arranged on the rotary wheel axle. The gearbox comprises a main shaft, and a magnet corresponding to the magnetic disk is arranged in the gearbox, arranged in a magnetic coupling device in a sleeved mode, and connected with the main shaft after meshing of multi-stage gears. The machine body comprises a main pipe, a machine body water inlet cavity is formed in the main pipe, a transmission shaft is arranged in the machine body water inlet cavity, the main shaft penetrates through the power control box water inlet cavity and then is connected with the transmission shaft, a water spray system is arranged at the lower end of the transmission shaft, and the power control box cavity is communicated with the machine body water inlet cavity.

Description

technical field [0001] The invention relates to a cleaning device, in particular to an oil tank cleaning device for various oil tankers in the shipbuilding industry, which uses crude oil or seawater as the cleaning medium, that is, a tank cleaning machine with magnetic drive. Background technique [0002] During oil tanker transportation, heavy components such as paraffin and asphalt in crude oil will continuously precipitate out of crude oil to form a thick layer of oil residue sediment. If the oil is not removed after unloading, after several voyages, the accumulation of oil residue will hinder the normal unloading of the oil tanker, and even greatly reduce the oil carrying capacity of the oil tanker. For the oil residue of oil tankers, the oil tank is generally cleaned by using the jet flow generated by the high-pressure fluid (0.4~1.2MPa) through the nozzle by using the tank washing machine. The amount of seawater discharged to the refinery and the need for manual clean...

Problems solved by technology

[0003] The existing tank washing machine equipment generally uses high-pressure working medium to drive the built-in rotating mechanism (turbine or runner) to obtain the power required for nozzle rotation, and then realize the automatic operation of the tank washing machine through this power; most tank washing machines The improvement is either aimed at the nozzle structure, or setting a deflector at the inlet to increase the driving force of the impeller, or adjusting the control mechanism for the nozzle, but the power transmission in them is all carried out by means of mechanical transmission, and the high-pressure medium is used in the cleaning machine. When flowing, the inevitable problem of mechanical transmission is the sealing problem. Poor sealing will cause the impurities in the working medium to wear the mechanical transmission parts, cause equipment failure, and reduce the reliability of the equipment.

In addition, the nozzle angle adjustment of most tank washing machines is to achieve 360° rotation in the plane, and there are many cleaning dead angles, which have a great impact on various tank washing processes and cleaning effects.
