Abstract
An airtight device for cleaning a rail tank car relates to a cleaning device of the rail tank car and resolves the problems of the existing cleaning device, such as harmful gas leakage, environment pollution, poor cleaning effect, and increase of protection cost and safety protection difficulty. The airtight device is characterized in that four hinges are respectively fixed on an upper cover plate and an oval lower cover plate; the upper end and the lower end of a movable ring are respectively hinged with the hinges fixed on the upper cover plate and the oval lower cover plate; the upper end of a rubber corrugated ring is fixed on the lower plane of the upper cover plate and the lower end of the rubber corrugated ring is fixed on the upper plane of the oval lower cover plate; an aqueous vapor purge pipe is arranged at the circle center of the device; and an oval rubber sealing plate is arranged on the lower plane of the oval lower cover plate. When the airtight device is used in cleaning, harmful gas can not be leaked out, thus resolving the problems of serious pollution on environment and great harm to the body health of cleaning workers; and the airtight device reduces protection cost and safety protection difficulty, improves cleaning efficiency, and has the advantages of simple structure, low cost and energy conservation.
Description
Technical field
The utility model relates to the rail tank car cleaning device.
Background technology
At present, the domestic rail tank car inwall is cleaned all adopts open type to clean, make a jar interior pernicious gas leak, environment to the working site causes severe contamination, cleaning performance is poor, wastes energy, and is big to the cleaning personnel's of field operation healthy harm, increase the class of safety protection of operating area simultaneously, increased the difficulty of protection cost and security protection.
The utility model content
The utility model leaks for the pernicious gas that solves in the existing cleaning way jar, to the environment of working site cause severe contamination, cleaning performance poor, waste energy, healthy harm to the cleaning personnel of field operation is big, increased the problem of the difficulty of protection cost and security protection, now provide a kind of rail tank car to clean and use obturator, the concrete technical scheme that addresses the above problem is as follows:
Rail tank car of the present utility model cleans uses obturator, by hinge, upper cover plate, the rubber corrugated ring, active ring, oval lower cover and oval rubber gasket sheet are formed, hinge is four, wherein on the lower plane that two are fixed on upper cover plate, two other is fixed on the last plane of oval lower cover, the upper end of active ring is hinged with two hinges that are fixed on the upper cover plate lower plane, the lower end of active ring is with to be fixed on the oval lower cover two hinges on the plane hinged, the upper end of rubber corrugated ring is fixed on the lower plane of upper cover plate, the lower end of rubber corrugated ring is fixed on the last plane of oval lower cover, oval rubber gasket sheet is located on the lower plane of oval lower cover, is provided with the aqueous vapor scavenge pipe at the circle centre position that installs.
The cleaning way of device of the present utility model cleans in adopting under air-tight state jar, pernicious gas is not leaked, solved the problem serious to the environmental pollution of working site, solved the big problem of the healthy harm of cleaning personnel to field operation, protection cost and security protection difficulty have been reduced, the structure of having taked hinge to be connected with active ring, the sealing surface of this device can universally be swung, and can effectively seal jar mouth that tilts, saved and cleaned used energy medium, improved cleaning efficiency, rubber slab has electrostatic conductive performance simultaneously, the static that produces in the cleaning process is derived rapidly, and security is good.This apparatus structure is simple, cost is low and the advantage of energy savings.
