A tank steam sealing cleaning device

Abstract

The invention discloses a tank steam airtight washing device. The upper end of a first drain pipe (11-1) penetrates through a drain pipe mounting hole to be fixedly connected with a hoisting piece (9), a second drain pipe (11-12) is sleeved in the first drain pipe (11-1), a chain wheel (11-5) is fixedly connected with the lower end of the first drain pipe (11-1), a chain passes through the chain wheel (11-5), the two ends of the chain are fixedly connected with a first cross bar and a second cross bar respectively, when a first lifting device drives the hoisting piece (9) to ascend or descend, the first drain pipe (11-1) ascends or descends, and then the second drain pipe (11-12) is shrunk inwards or expanded outwards relative to the first drain pipe (11-1). The tank steam airtight washing device can improve hoisting speed and reduce hoisting space, ensures that the device can safely conduct hoisting away and compressing car washing operation in space with the limited height, and can improve car washing operating efficiency and reduce labor intensity and car washing cost.

Description

technical field [0001] The invention relates to the technical field of tank car cleaning, in particular to a tank steam sealing cleaning device. Background technique [0002] In rail and road transport, tank cars for transport are frequently subjected to tank cleaning operations. At present, the cleaning tanks have been using the open steam cleaning technology. The open steam cleaning technology has an open tank mouth. During the steaming process, most of the steam is evaporated from the tank mouth immediately after a small cycle in the tank, and the steam utilization rate is low. There is a large amount of steam wasted, and some parts in the tank are difficult to clean, which has the following disadvantages: [0003] 1. The utilization rate of steam is low, the waste of steam is large, and the cost of car washing is high; [0004] 2. The temperature in the tank generally can only reach about 80-90°C, which makes it difficult to cook some parts in the tank; [0005] 3. Th...

AI Technical Summary

Problems solved by technology

At present, the cleaning tank has been using the open steam cleaning technology. The open steam cleaning technology has the tank mouth open. During the steaming process, most of the steam is evaporated from the tank mouth after a small cycle in the tank, and the steam utilization rate is low. There is a large amount of steam wasted, and some parts in the tank are difficult to clean, which has the following disadvantages:

[0003] 1. The utilization rate of steam is low, the waste of steam is large, and the cost of car washing is high;

[0004] 2. The temperature in the tank generally can only reach about 80-90°C, which makes it difficult to cook some parts in the tank;

[0005] 3. The cooking time is long, the efficiency of car washing is low, and the work intensity of workers is relatively high;

[0006] 4. The residual items (oil, chemicals, etc.) in the tank volatilize with the steam from the tank mouth to the atmosphere, causing serious air pollution, poor working environment on site, and affecting the safety of operators

[0007] 5. When washing the tank, the steam noise is loud
