Among Fig. 4-Fig. 7:
The specific embodiment
Based on the existing compressed air drying treatment system of using dual cartridge air dryer; The utility model has carried out optimal design; It is dry that two air dryer parallel connections are provided with synchronous participation air feed; To bring into play the air dried drying capacity of the bitubular to greatest extent, guaranteeing to carry higher rate of load condensate on the basis that drier is fully regenerated.Specify this embodiment below in conjunction with Figure of description.
See also Fig. 4 and Fig. 5, wherein, Fig. 4 is the formation sketch map of the said compressed air drying treatment system of first embodiment, and Fig. 5 is the schematic diagram of the treatment system of compressed air drying shown in Fig. 4.
As shown in the figure, this compressed air drying treatment system comprises the air dryer that two parallel connections are provided with: first air dryer 41 and second air dryer 42.The input gas port 421 of the input gas port 411 of first air dryer 41 and second air dryer 42 all is communicated with air compressor machine 43 through pipeline, first air dryer 41 work gas port 412 and the work gas port 422 of second air dryer 42 all be communicated with the air inlet of pneumatic apparatus 44.In this programme, pneumatic apparatus 44 is the four-loop protection valve of chassis walking brakes, and its concrete operation principle is identical with prior art, so this paper does not do special qualification.
With two corresponding respectively air tanks that are provided with of air dryer, wherein, the gas port of the first regeneration air tank 45 is communicated with the air storage recoil gas port 413 of first air dryer 41; The gas port of the second regeneration air tank 46 is communicated with the air storage recoil gas port 423 of second air dryer 42; And; With first air dryer 41 accordingly; First pressure regulator valve 47 is arranged between the work gas port 412 and off-load feedback port 414 of first air dryer 41, and simultaneously, the output gas port of first pressure regulator valve 47 also is communicated with the off-load feedback port 424 of second air dryer 42.
In the course of work; Air compressor machine 43 output pressure gas to the first air dryers 41 and second air dryer 42; Via exporting pneumatic apparatus 44 from the gas port 412 of working synchronously to work gas port 422 respectively after its inner drier drying; The dry air of predetermined pressure is provided, supplies Full Vehicle System to use gas.
When system pressure (the work gas port 412 of first air dryer 41) when reaching the setting rated operating pressure of first pressure regulator valve 47; 47 switching-overs of first pressure regulator valve; System pressure gas acts on unloader separately from the off-load feedback port 414 of first air dryer 41 and the off-load feedback port 424 of second air dryer 42 respectively; Unloader is opened the off-load that realizes two air dryers, and system pressure is in preset state all the time.Meanwhile; The compressed air drier in the air storage recoil gas port 423 of the air storage of the first air dryer 41 recoil gas port 413 and second air dryer 42 recoils corresponding drying chamber respectively in the first regeneration inflator 45 and the second regeneration inflator 46, the regenerative process of two air dryers of completion.So far, accomplish drying, off-load process from the compressed air of air compressor machine 43 synchronously via two driers.
In this programme, first pressure regulator valve 47 can separate configurations; Perhaps can be as shown in the figure, first air dryer 41 adopts the air dryer of band pressure regulator valve, that is to say that first pressure regulator valve 47 and first air dryer 41 become one.Obviously, the configuration that becomes one is convenient to realize system layout and assembling more.
Because the frequent startup of system element is used in realizing the course of work, occurs the component failure problem inevitably.For guaranteeing the security reliability of system's operation, can do further specifically to see also Fig. 6 to the said compressed air drying treatment system of first embodiment, the figure shows the schematic diagram of compressed air drying treatment system shown in second embodiment.
As shown in Figure 6, the difference of this embodiment and first embodiment is to have additional second pressure regulator valve 48.Particularly, second pressure regulator valve 48 is arranged between the work gas port 412 and off-load feedback port 424 of second air dryer 42, and the output gas port of second pressure regulator valve 48 also is communicated with the off-load feedback port 414 of first air dryer 41.The operation principle of this second pressure regulator valve 48 and first pressure regulator valve 47 is identical, repeats no more at this.
In the course of work, the operating pressure that two pressure regulator valves are exported according to the respective air drier is respectively confirmed its off-load feedback output, and the off-load feedback signal of each pressure regulator valve exports the off-load feedback port of two air dryers simultaneously to, to realize Synchronization Control.Compare with first embodiment, a redundancy that pressure regulator valve is another pressure regulator valve in this programme can be guaranteed effectively to improve the compressed air capacity and carry higher rate of load condensate reliable guarantee is provided, and guarantees that further security of system moves reliably.
Equally, second pressure regulator valve 48 promptly can separate configurations, air dryer that also can employing band pressure regulator valve as shown in the figure, and second pressure regulator valve 48 and second air dryer 42 become one.
Preferably, the rated operating pressure scalable of first pressure regulator valve 47 and second pressure regulator valve 48 is to adjust its rated operating pressure according to different applying working conditions.In addition, for further improving system works stability, the rated operating pressure of first pressure regulator valve 47 and second pressure regulator valve 48 equates.Obviously, if the rated operating pressure of two pressure regulator valves 48 is inconsistent, then the higher pressure regulator valve of rated operating pressure becomes the redundancy of another pressure regulator valve truly.
Except that aforementioned compressed air drying treatment system, this embodiment also provides a kind of wheeled crane
See also Fig. 7, this figure is the overall structure sketch map of the said wheeled crane of this embodiment.
This crane comprises main functional parts such as chassis, Lifting device and winding plant, and this chassis braking with the compressed air drying treatment system specifically as previously mentioned.Because each main function components can adopt existing techniques in realizing, so this paper repeats no more.
What specify is; The compressed air drying treatment system that the utility model provides is not limited to and is applied to wheeled crane; This system can also be applied to the Pneumatic braking system of other industrial wheeled equipments such as wheeled elevating fire truck, as long as satisfy the use needs all in the scope that the application asks for protection.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
