Description
Technical field
The present invention relates to special equipment, in particular to a kind of displacement drying unit for groove tank.
Background technology
Groove tank is the important tool of shipping storage liquid material, is widely used in the accumulatings such as oil, chemical industry, food oil neck
Domain.At present common groove tank include railway tank car, road tanker, tank container, gas station's buried tank and all kinds of storage tanks,
Storage tank, below by taking railway tank car as an example.
In order to ensure the transportation safety and quality itself of groove tank car internal liquid, must be in-car to groove tank when changing the outfit
Wall periodically carries out spy and washes.It is required for carrying out air displacement and drying and processing to groove tank car inside before and after cleaning every time, in general
Frequently with the form for being passed through hot blast in drying and processing.
But, groove tank car belongs to oblong structure, and due to hot blast, cannot to be deep into inwall attached in displacement drying course
Closely, therefore effect is poor, there is blind area.And due to there is substantial amounts of inflammable, explosive, Toxic in this displacement drying course
Matter, therefore be not suitable for manually playing tank to be processed.
In order to improve job safety degree, at present common displacement drying mode is by wind by an easy small-sized threeway
Or steam or inert gas send into groove tank manhole lower section, cause that this displacement drying mode energy consumption is big, capacity usage ratio is low, in a large number
Energy not yet reach distal end without using escaping from manhole nearby, therefore drying effect is difficult to ensure that, there is power consumption, consumes
When, blind area the problems such as, while substantial amounts of toxic gas is directly discharged in air, pollute environment, damage operator's health.
The content of the invention
For problem present in the displacement drying of current groove tank, it is an object of the invention to provide a kind of putting for groove tank
Drying unit is changed, such that it is able to gas is covered into groove tank inner surface in restricted clearance, quick, efficient, uniform, non-blind area is realized
And the groove tank inside displacement drying of safety, and then operation effectiveness is improved, and energy consumption is reduced, reduce the activity duration.
In order to realize this purpose, the invention discloses a kind of displacement drying unit for groove tank, including：
- hollow ventilating pipe, the top of the hollow ventilating pipe is hose construction, and middle part bottom is fixed with nozzle；

Wherein the 5th connecting rod is parallel with third connecting rod, and six-bar linkage is parallel with fourth link, so as to form two parallel four
The rock-steady structure of side shape.
As further preferred embodiment, a fixture is also included disclosed in the present invention, the fixture is supported in
Groove tank manhole top surface, the fixture offers the through hole fixed for hollow ventilating pipe and movable loop bar.So that its
Convenient in use, fixation is more consolidated.This fixture both can be the disc knot matched with manhole upper end
Structure, or do not interfere with manhole upper end, it is easy to the square structure of support or other polymorphic structures.
Further, as it is a kind of preferably, the invention discloses the hollow ventilating pipe be socketed by more piece hollow pipeline and
Into.Hollow pipeline internal diameter near people's nose end is larger, and as it stretches out, the internal diameter of hollow pipeline is gradually reduced, so as to shape
Into the more piece hollow pipeline structure for connecting together that can be shunk.Matched, we are also provided with hollow pipeline
Safety cable, so as to the reliability that hollow pipeline when ensureing to operate is taken down the exhibits.
Meanwhile, we are still further preferably provided with long nozzle in each bottom for saving hollow pipeline.So that its
In displacement drying course, gas distribution is more uniform, and area coverage is wider.
Preferably, the long nozzle is arranged on the section circle that hollow ventilating pipe is respectively saved along radiation direction.
On same section circle position, two, or three are respectively arranged with, are spaced the long spray of certain angle
Mouth, so as to improve the distribution consistency degree of air-flow.
Further, we also disclosed and lifting body is provided with the top of the outer tube, preferably this lifting body
For gas spring.So that the motion of movable loop bar is more smooth, stable.
Meanwhile, as a kind of preferred embodiment, we also disclosed on the manhole also to support and be provided with gas sampling cover, its
On be connected with guide pipeline.In due to replacing drying course, substantial amounts of organic solvent volatilization is escaped together with vapor from manhole
Go out, thus be provided with after gas sampling cover, can effectively by gas sampling, and concentration is processed, and meets eco-friendly need
Will.
After using technical scheme disclosed in this invention, many crane bit stream water automated jobs are realized, energy consumption can be reduced
About 60%, displacement drying time saves 50%, and displacement drying is thorough, without dead angle, significantly improves product quality.Simultaneously because need not
Personnel enter, and realize the outer safety work of tank, and waste gas unifies collection and purification and processes qualified discharge, realizes environmental friendliness.
