Scissor-cross locked type steam closed cleaning device for tank truck

Abstract

The invention discloses a scissor-cross locked type steam closed cleaning device for a tank truck. The scissor-cross locked type steam closed cleaning device comprises a scissor-cross closed locking mechanism, a steam inlet pipe and a sewage discharging pipe, wherein the steam inlet pipe is used for injecting steam, and the sewage discharging pipe is used for discharging sewage after steam cleaning is ended. The closed locking mechanism is connected to a tank opening in a fitted and sealed manner. The steam inlet pipe and the sewage discharging pipe lead to the interior of a tank. The closed locking mechanism comprises a seal washer, a first gland, an ascending-and-descending suspension frame, an ascending-and-descending power component and guiding rods, wherein the seal washer is arranged in a manner that the seal washer is closely attached to the end face of the tank opening; the first gland is located on the seal washer; the ascending-and-descending suspension frame moves in the height direction of the tank opening; the ascending-and-descending power component is fixed relative to the first gland; the ascending-and-descending power component is connected with the ascending-and-descending suspension frame so that the ascending-and-descending suspension frame can be driven to move; each guiding rod extends outwards in the radial direction of the tank opening of the tank; a slide block is arranged on each guiding rod; each slide block is connected with a clamping hook which is used for conducting clamping and leaning in the tank and extends outwards in the radial direction of the tank opening; and the two clamping hooks are hinged to each other in a staggered manner, so that a scissor-cross type structure is formed. By means of the cleaning device, locking force generated in the cleaning process is uniformly applied to the end face of the tank opening, and no loading burden is brought to other equipment and facilities.

Description

technical field [0001] The invention relates to a device for steam sealing cleaning of tank cars, in particular to a scissors and fork 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 is large, and t...

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
