A tank car condensed heavy oil heating crane tube pendant arm mechanism

Abstract

The invention discloses a congealed heavy oil heating drop arm mechanism of a loading arm of a tank vehicle and belongs to the technical field of mechanical equipment. The congealed heavy oil heating drop arm mechanism comprises a telescopic drop arm, a sealing cover, an oil tray fixing ring, a scraper ring, a cylinder, a steam jet device and a hydraulic cylinder. The upper end of the telescopic drop arm communicated with steam is connected with a pneumatic hoist mechanism, and the lower end of the telescopic drop arm is provided with the steam jet device. The steam jet device comprises a steam jet head, steam jet tubes and a fixing support. The steam jet head is communicated with the bottom of the telescopic drop arm and further fixedly connected with the same. A circular groove is provided with the scraper ring and is formed in the oil tray fixing ring. The cylinder penetrates a circular hole in the center of the sealing cover to be fixedly connected with the lower end of the oil tray fixing ring. A steam blowing inlet is formed in the cylinder. The congealed heavy oil heating drop arm mechanism has the advantages that the telescopic drop arm is guaranteed being clean after use, avoiding mixing among different oils; the oils are heated, and the oils adhered to the telescopic drop arm are recycled, so that resource waste is reduced, production efficiency is improved, and cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and more specifically relates to a tank car condensed heavy oil heating crane tube pendant arm mechanism. Background technique [0002] The crane tube is a special equipment in the process of fluid loading and unloading in the petrochemical industry, also known as the fluid loading and unloading arm. It uses a rotary joint to connect rigid pipes and elbows to realize the movable equipment for transporting liquid media between trains, car tankers and trestle storage and transportation pipelines, replacing the old-fashioned hose connections. It has high safety and flexibility. properties and long lifespan. It is mostly used for liquid loading and unloading in petroleum and chemical wharfs, and the medium in the pipe is oil, water, etc. However, the freezing point of crude oil is between -50°C and 35°C, so it is easier to solidify, and in the application of existing technologies, tank...

AI Technical Summary

Problems solved by technology

However, the freezing point of crude oil is between -50°C and 35°C, so it is easier to solidify, and in the application of existing technologies, tank trucks may transport petroleum and chemical wharf liquids to areas with lower temperatures, or due to weather conditions The reason is that the temperature is low, and the petroleum or chemical wharf liquid in the tank car will drop below the freezing point and solidify into a solid state. Therefore, the crane tube cannot be used to unload the crude oil immediately after it is transported to the destination. The crude oil in the tank car must be unloaded first. Crane tubes can be used to unload crude oil after heating and melting, so there is an urgent need for a device that can heat crude oil in tank cars, that is, a tank car condensed heavy oil heating crane tube pendant arm mechanism
