Below in conjunction with the drawings and specific embodiments, structure of the present utility model is described in detail.
As shown in Figure 1, described car body 1 time end is provided with walking wheel 12, and described car body 1 front end is provided with handle 11, can be conveniently pushed to by the utility model bottom U-tube by car body 1 and part container bottom, it may also be useful to more convenient; In specific embodiment, the rubber wheel that described walking wheel 12 is strap brake braking.
As shown in Figure 1, described tank body 2 is fixedly installed on the upside of described car body 1, described tank body 2 one end is provided with the first liquid level indicator 21 being used to indicate high liquid level (in tank body the liquid level of liquefied gas), is respectively equipped with safety valve 23, tensimeter 24, emptying pipe connecting 25, stamping connection pipe 26 and liquefied gas access tube 27 on the upside of described tank body 2.
Wherein, the outlet of described safety valve 23 is all connected with low tile system with described emptying pipe connecting 25, and when described tank body 2 pressure raises extremely, the action of described safety valve 23 is opened, part gas phase is led to into low tile system, and it mainly plays the effect effectively controlling pressure in tank body 2; Due to liquefied gas enter in tank body time, first gas-liquid separation can be carried out, gas phase is non-condensable gas (comprising some sulfurous gass etc.), liquid phase is liquefied gas and water layer (wherein water layer is positioned at the lowest layer), gas phase portion is led to into low tile system by described emptying pipe connecting 25, thus effectively avoids gas waste and reveal the problem bringing environmental pollution.
Described stamping connection pipe 26 and punching press nitrogen gas supply system connectivity, described liquefied gas access tube 27 stockpiles position by flexible pipe 28 and liquefied gas and is connected, and described liquefied gas access tube 27 is provided with chain control valve 271.
In concrete work, in described tank body 2, pressure exceedes set(ting)value (this pressure set points is the maximum of in advance setting, when being mainly full of liquefied gas, the combination pressure of liquefied gas and punching press nitrogen) time, described chain control valve 271 action is closed, and described liquefied gas access tube 27 stops ventilation, opens the valve on liquefied gas drain tube 223 at this moment, under the effect of pressure nitrogen gas, liquefied gas can be pressed into material returning system.
In described tank body 2, lower than set(ting)value, (this pressure set points is the Schwellenwert set in advance to pressure, when mainly liquefied gas is emptying, punching press nitrogen is separated the combination pressure of liquid phase with partial liquefaction gas) time, the action of described chain control valve 271 is opened, and described liquefied gas access tube 27 recovers ventilation.
Therefore, under the control of chain control valve 271, this device can carry out uninterruptedly automatic feeding and exhaust, gaseous tension in whole tank body 2 is within the scope of a pressure range all the time, reaches running balance, it is achieved automatically control, effectively reduce human input, it is to increase working efficiency.
Pressurising pipe connecting 26 connects nitrogen, and liquefied gas outlet is connected to sent system, and after whole system connects inspection examination leakage, liquefied gas is entered in tank 2 by liquefied gas entrance, and by nitrogen pressure by the liquefied gas press-in material returning system in tank body 2.
Owing to liquefied gas there will be oily water separation phenomenon in tank body after gas-liquid separation, water layer can be deposited on below liquefied gas then.
For ease of this part moisture is discharged, it is provided with on the downside of described tank body 2 and the liquid bag 22 that described tank body 2 is connected, this liquid bag 22 is specially the small canister body being arranged at and arranging below tank body 2, described liquid bag 22 is back taper mouth 222 with described tank body 2 junction, described liquid bag 22 side is provided with the 2nd liquid level indicator 221 being used to indicate low liquid level (in liquid bag 22 water layer liquid level), and described liquid bag 22 times ends are connected with liquefied gas drain tube 223.
In concrete work, after oily water separation bottom tank body 2, water layer is in bottom, mainly concentrate in liquid bag 22, therefore, it is possible to by the liquid level change on the 2nd liquid level indicator 221, valve on control liquefied gas drain tube, discharges bottom moisture, reduces the content being pressed in material returning system liquefied gas moisture as far as possible; Then, opening the valve on liquefied gas drain tube after discharging water layer, liquefied gas is pressed into liquefied gas material returning system.
Prior art is for safety valve 23 and chain control valve 271, applies very general in the industry; It is prior art for the first liquid level indicator 21 and the 2nd liquid level indicator 221, mainly make use of the principle of communicating vessels, be similar to U plastics tubing; Can easily realize with above-mentioned technology those skilled in the art, be not described in detail at this.
In specific embodiment, as shown in Figure 2, being provided with support 13 on the upside of described car body 1, described support 13 is provided with card and buckles, and described tank body 2 is fixed on described card and smashs.
For described card button, can there is different set-up modes, preferred as in the utility model, mainly contain following two kinds of modes.
The first implements mode
Described card button comprises two complete identical semicircle cards and buckles 131, the described semicircle card button 131 being in lower end is fixedly connected with described support 13 (can be welded on support 13), two described semicircle card button 131 one end are hinged, the other end is respectively equipped with web plate 1311, described web plate 1311 is provided with connection through hole, like this, annular snap can be formed after semicircle card button 131 docking described in two, thus blocked by tank body 2, and then the bolt through connecting through hole is utilized to be clamped by tank body 2.
Implement mode for 2nd kind
Described card button comprises two complete identical semicircle cards and buckles 131, the described semicircle card button 131 being in lower end is fixedly connected with described support 13, the two ends of described semicircle card button 131 are respectively equipped with web plate 1311, described web plate 1311 is provided with connection through hole, like this, also can form annular snap after two described semicircle card button 131 docking, thus tank body 2 is blocked, and then utilize the bolt through connecting through hole to be clamped by tank body 2.
Implementing mode as the first, owing to two semicircle card one end are hinged, only need to upwards be opened along hinged place by clamp above and can be put into by tank body, this kind of mode operates fairly simple convenience; But this kind of mode, a kind of clamp can only be applicable to a kind of tank body.
Mode is implemented as the 2nd kind, due to the direct splits of two semicircle cards, although to implement mode simple to operate not as the first, but, after tank body specification is suitably amplified, still utilize clamp to compress tank body by bolt.
But owing to above-mentioned two kinds of enforcement modes all can realize the fixing of tank body, therefore, above-mentioned two kinds of enforcement modes all fall into protection domain of the present utility model.
Further, it is provided with asbestos washer 133 between described card button and described tank body 2, it is possible in the utility model moving process, alleviate vibrations, the elements such as available protecting tensimeter as far as possible.
Except the technology feature described in specification sheets, it is the known technology of those skilled in the art.
Preferred implementation of the present utility model and embodiment have been made detailed description by by reference to the accompanying drawings; but the utility model is not limited to the above-described embodiment and examples example; for those skilled in the art; without departing from the concept of the premise utility; can also making some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
