Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.
Referring to the attached drawings 1-5, the high-power adjustable screw air compressor unit comprises a box body 1, and a driving motor 10, a screw air compressor 20 and an air storage tank 30 are sequentially arranged in the box body 1. The three devices are mutually connected and driven, and the devices with different specifications are selected according to the actual working environment, so that the adjustable screw air compressor unit can achieve larger working power (the specific range is 200 and 355 kw). So as to meet the production requirement of the large-scale casting industry.
In order to further improve the dryness of the produced compressed air, one side of the air storage tank 30 is also connected with a suction dryer 40 and a cold dryer 50, and the compressed air stored in the air storage tank 30 is subjected to suction dryer cold drying treatment in the use and transmission process in sequence through the suction dryer 40 and the cold dryer 50, so that the treated compressed air can effectively reach higher dryness to meet the use requirements of the casting industry.
In order to adjust the working power of the air compressor unit and meet the changing demand of production to achieve the purpose of saving energy consumption, the driving motor 10 is further connected with a variable frequency controller (not shown in the figure), and a volume adjusting valve 2 is further disposed between the air storage tank 30 and the screw air compressor 20. The air input of the air storage tank 30 is adjusted through the air consumption of the air consumption end, the driving motor 10 is adjusted through the variable frequency controller, and the capacity of compressed air generated by the screw air compressor 20 and stored in the air storage tank 30 is further adjusted. The combined action of the volume adjusting valve 2 and the variable frequency controller controls the air storage capacity in the air storage tank 30, and the work (energy consumption) of the generated air of the screw air compressor 20 and the driving motor 10 is equivalent to the air consumption capacity of the air consumption end. The gas capacity of the gas end is 50m 3 The volume control valve 2 adjusts the amount of intake air in the air tank 30 to 50m 3 And correspondingly regulating the gas production of the driving motor 10 and the screw air compressor 20 to be constant at 50m through a variable frequency controller 3 To effectively reduce the gas production requirements of the drive motor 10 and screw air compressor 20 to its maximum rated capacity (e.g., rated maximum capacity of 300 m) 3 ) And the high energy consumption is consumed and lost, and the high energy efficiency performance of the air compressor set is realized. Preferably, the air compressor set is a two-stage screw type air compressor 20 and a driving motor 10 to meet the requirement of high-power operation.
Meanwhile, in order to stably and reliably adjust the air storage capacity of the air storage tank 30 and improve the stable and reliable adaptive adjustment of the air compressor set according to the air storage capacity through the combined action of the synchronous volume adjusting valve 2 and the variable frequency controller, a volume adjusting device is further arranged on the air storage tank 30.
Specifically, as shown in fig. 2 to 3, the volume adjusting device includes a driving cylinder 3 fixedly disposed at the bottom of the air storage tank 30, the driving cylinder 3 has a piston rod 31 vertically extending upwards into the air storage tank 30, and a separation sealing device for separating the air storage volume of the air storage tank 30 is disposed at the top end of the piston rod 31. Preferably, an automatic controller (not shown) is connected to the driving cylinder 3, and the volume adjusting valve 2 and the variable frequency controller are simultaneously connected to the automatic controller to realize synchronous adjustment of the three. The capacity adjustment function of the gas storage tank 30 is that the gas capacity of the gas end is fed back to the automatic controller and fed back to the driving cylinder 3 again, so that the driving piston rod 31 and the separation sealing device at the top of the driving piston rod move up and down in the gas storage tank 30, and the gas storage inner cavity in the gas storage tank 30 is precisely sealed and divided, so that the gas storage tank 30 has the gas storage capacity equal to the gas end capacity, the compressed air stored in the gas storage tank 30 is ensured to have rated gas storage pressure, and the defect that the screw type air compressor 20 and the driving motor 10 are repeatedly opened and closed due to the fact that the gas storage capacity is stored into the gas storage tank 30 with larger capacity and the gas transmission pressure is insufficient is avoided.
Specifically, as shown in fig. 4, the separation sealing device includes a separation main plate 4 fixedly disposed at the top end of the piston rod 31 and perpendicular to the inner wall of the gas storage tank 30, a separation pressing plate 5 is disposed at the top of the separation main plate 4 in parallel, a compression cavity 101 is reserved between the separation main plate 4 and the separation pressing plate 5, and a sealing ring 6 having an outer diameter larger than the height of the compression cavity 101 and closely attached to the inner wall of the gas storage tank 30 is sleeved around the edge of the compression cavity 101. Through the effect of separating mainboard 4 and 5 tip of partition clamp plate and compressing tightly to sealing washer 6 for its outer wall hugs closely and realizes sealedly on the 30 inner walls of gas holder after the extrusion of sealing washer 6, reciprocates through driving actuating cylinder 3 drive piston rod 31, makes to separate clamp plate 5 and sealing washer 6 and the 30 inner walls of gas holder jointly seal the interior chamber of gas holder 30 and cut apart, with the storage volume of the interior chamber adaptation in the gas storage volume after the realization was separated.
