Tank car upper fixed beam connecting rod locking type steam airtight cleaning device

Abstract

The invention discloses an upper fixed beam connecting rod locking type airtight steam cleaning device for a tank truck. The device comprises an airtight locking mechanism, a steam inlet pipe for injecting steam and a dirt discharge pipe for discharging dirt after steaming and washing. An airtight locking device is connected to a tank opening in a matched and sealed mode. The steam inlet pipe and the sewage discharge pipe lead to the inner part of a tank. The airtight locking device comprises a sealing pad arranged at the end surface of the tank opening, a first grand located on the sealing pad, a lifting suspension frame moving in the height direction of the tank opening, a lifting power element fixed to the first grand, connected to the lifting suspension frame and used for driving the lifting suspension frame to move, and a fixed beam basically and fixedly connected relative to the tank opening and extending into the tank. Clamping hooks are hinged to the part, extending into the tank, of the fixed beam. A connecting rod mechanism formed by the clamping hooks and the fixed beam controls opening and closing of the clamping hooks and is driven by the lifting suspension frame. According to the upper fixed beam connecting rod locking type airtight steam cleaning device for the tank truck, the locking force generated by the locking mechanism in a cleaning system acts uniformly on the end surface of the tank opening, and load burden on other equipment and facilities can be avoided.

Description

technical field [0001] The invention relates to a device for steam sealing cleaning of tank cars, in particular to an upper fixed beam connecting rod locking type steam sealing cleaning device suitable for cleaning tank cars with closed high-temperature steam. Background technique [0002] Tank cars require frequent cleaning operations. At present, the tank car uses the open steam washing technology, which has an extremely low steam utilization rate. During the open-top steaming process, the mouth of the tank is open, and most of the steam evaporates from the mouth of the tank immediately after a small circulation in the tank, which not only wastes a lot of steam, but also seriously pollutes the atmospheric environment. Due to the low temperature in the tank, some parts are difficult to cook clean. [0003] To sum up, the existing open steam washing technology for tank cars has the following disadvantages: [0004] 1) The steam utilization rate is low, the waste of steam ...

AI Technical Summary

Problems solved by technology

[0004] 1) The steam utilization rate is low, the waste of steam is large, and the cost of car washing is high;

[0005] 2) The temperature inside the tanker can generally only reach about 80°C, which makes it difficult to cook some parts in the tank;

[0006] 3) The cooking time is long, the efficiency of car washing is low, and the work intensity of workers is relatively high;

[0007] 4) The residual items (oil, chemicals, etc.) in the tank car volatilize from the tank mouth into the atmosphere with the steam, causing serious air pollution, poor working environment on site, and affecting the safety of operators

[0008] 5) When cleaning the tanker, the steam noise is loud
