Description

Technical Field

[0001] This invention relates to an exhaust regulation structure for a closed-circuit air compressor. Background Technology

[0002] Currently, screw air compressors are used to compress air and provide power to systems such as factory production lines and construction machinery. Compared with traditional piston air compressors, screw air compressors have the characteristics of high energy efficiency, compact structure, and low noise. In recent years, they have shown a trend of gradually replacing piston air compressors in various fields. Existing screw air compressors often require cooling of the compressed air to reduce its temperature before discharge, depending on the needs. Sometimes, however, cooling is not required. Therefore, flexible adjustment and control of the discharged compressed air are necessary to meet the appropriate usage requirements. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention provides a closed-loop air compressor exhaust regulation structure that allows for adjustment of whether cooling is performed as needed.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0005] A closed-loop air compressor exhaust regulating structure includes a bottom support frame, a compressor housing, an air inlet pipe, an adjustable flow guiding mechanism, an exhaust pipe, and a telescopic connecting pipe. A bottom support frame is installed on each of the lower sides of the compressor housing. An air inlet pipe is installed on the upper side of one end of the compressor housing. The adjustable flow guiding mechanism is installed at the bottom of the compressor housing. The adjustable flow guiding mechanism includes a cooling housing, a ventilation pipe, a closed partition, a connecting crossbar, a longitudinal guide rod, a side protrusion, a sealing block, and a pressure spring. The cooling housing is installed at the bottom of the compressor housing. The cooling housing is vertically floating between the two bottom support frames. A closed partition is installed inside the cooling housing, dividing it into a lower cooling chamber and an upper exhaust chamber. A through-hole groove and a ventilation groove are provided on both sides of the closed partition. A pressure spring is installed on each of the bottom sides of the cooling chamber. A sealing block is installed on the upper end of each pressure spring. The through-hole groove and ventilation groove... A sealing block is distributed directly below the cooling box; the pressure spring presses the sealing block upwards to seal against the lower side of the through groove and the vent groove; the upper end of the vent pipe is located inside the lower part of the compression box, and the lower end of the vent pipe enters the exhaust chamber; a side protrusion is installed on each side of the lower end of the vent pipe; a connecting crossbar is installed on one side of the vent pipe, and the connecting crossbar is located inside the exhaust chamber; a longitudinal guide rod is installed on the lower side of the end of the connecting crossbar; the cooling box moves upwards, causing the sealing partition to move upwards, and the through groove of the sealing partition passes through the side protrusion at the lower end of the vent pipe, so that the side protrusion presses against the sealing block and moves downwards in the cooling chamber, so that the lower end of the vent pipe is located in the cooling chamber, and at the same time, the vent groove of the sealing partition passes through the longitudinal guide rod and moves upwards, so that the lower end of the longitudinal guide rod presses against the sealing block and moves downwards, so that the vent groove is open; the exhaust pipe is installed on a bottom support frame; a telescopic connecting pipe is installed at the inner end of the exhaust pipe, and the inner end of the telescopic connecting pipe is connected to one side of the exhaust chamber.

[0006] Furthermore, the cooling box body is provided with side connecting rods on both sides; the outer end of each side connecting rod is provided with a sliding locking block; the inner side of the bottom support frame is provided with longitudinal slots; the sliding locking block slides up and down and locks into the longitudinal slots.

[0007] Furthermore, it also includes an upper and lower drive assembly; the upper and lower drive assembly includes a drive motor, a drive shaft, and a longitudinal screw; the drive motor is installed on the bottom inner side of a bottom support frame; the drive shaft is installed at the upper end of the drive motor; the longitudinal screw is installed at the upper end of the drive shaft; the longitudinal screw is rotatably engaged in a longitudinal slot and threadedly engaged with a sliding engagement block.

[0008] Furthermore, the outer perimeter of the ventilation duct is slidably and sealed to the through-groove.

[0009] Furthermore, both the longitudinal guide rod and the venting groove have circular cross-sections; the diameter of the longitudinal guide rod is smaller than the diameter of the venting groove.

[0010] Furthermore, the cooling chamber of the cooling box is provided with a coolant inlet pipe and a coolant outlet pipe on both sides.

[0011] Furthermore, a screw is provided inside the compression chamber; a power motor is provided outside the other end of the compression chamber; the power motor is connected to one end of the screw.

[0012] The beneficial effects of this invention are as follows:

[0013] This invention uses the vertical movement of the cooling chamber to determine whether the discharged compressed air is cooled, allowing for adjustment based on actual conditions. When the cooling chamber moves upward, it causes the sealing partition to move upward as well. The through groove of the sealing partition connects to the side protrusion at the lower end of the ventilation pipe, causing the side protrusion to press against the sealing block and move downward within the cooling chamber, positioning the lower end of the ventilation pipe within the cooling chamber. Simultaneously, the ventilation groove of the sealing partition connects to the longitudinal guide rod and moves upward, causing the lower end of the longitudinal guide rod to press against the sealing block and move downward, thus opening the ventilation groove. In this way, compressed air enters the cooling chamber through the ventilation pipe. Inside, compressed air passes through the coolant in the cooling chamber, then through the venting groove into the exhaust chamber, and finally exits through the telescopic connecting pipe and the exhaust pipe. When the cooling box moves downward, the sealing partition moves downward, causing the cooling chamber to detach from the lower end of the venting pipe and the lower end of the longitudinal guide rod. At the same time, the sealing block is pressed upward by the pressure spring, causing the sealing block to seal and block the through groove and venting groove of the sealing partition. At this time, the lower end of the venting pipe is located in the exhaust chamber, and the compressed air is discharged through the venting pipe, then through the telescopic connecting pipe and the exhaust pipe, thus achieving convenient adjustment and drive.

At the same time, the ventilation groove 432 of the closed partition 43 passes through the longitudinal guide rod 45 and moves upward, so that the lower end of the longitudinal guide rod 45 presses against the sealing block 46 and moves downward, so that the ventilation groove 432 is open. The exhaust pipe 5 is installed on a bottom support frame 1. The inner end of the exhaust pipe 5 is installed with a telescopic connecting pipe 6, and the inner end of the telescopic connecting pipe 6 is connected to one side of the exhaust chamber 411.

[0025] like Figures 1 to 9 As shown, to facilitate the stable up-and-down sliding of the cooling box 41, it is further preferred that the cooling box 41 is provided with side connecting rods 413 on both sides; the outer end of the side connecting rods 413 is provided with a sliding locking block 414; the inner side of the bottom support frame 1 is provided with a longitudinal locking groove 11; the sliding locking block 414 is slidably locked onto the longitudinal locking groove 11.

[0026] like Figures 1 to 9 As shown, to drive the cooling box 41 up and down, a vertical drive assembly 5 is further included; the vertical drive assembly 5 includes a drive motor 51, a drive shaft 52, and a longitudinal screw 53; the drive motor 51 is installed on the inner bottom of a bottom support frame 1; the drive shaft 52 is installed at the upper end of the drive motor 51; the longitudinal screw 53 is installed at the upper end of the drive shaft 52; the longitudinal screw 53 is rotatably engaged in the longitudinal slot 11 and threadedly connected to the sliding engagement block 414.

At the same time, the sealing block 46 is pressed upward by the pressure spring 48, causing the sealing block 46 to seal and block the through groove 431 and the venting groove 432 of the sealing partition 43. At this time, the lower end of the venting pipe 42 is located in the exhaust chamber 411, and the compressed air is discharged through the venting pipe 42, then through the telescopic connecting pipe 6 and the exhaust pipe 5, thus achieving convenient adjustment and drive.
