Description

Technical Field

[0001] This utility model belongs to the field of air compressor gas drying technology, and in particular relates to a height-adjustable compressed air drying structure. Background Technology

[0002] An air compressor is a device that converts mechanical energy into gas pressure energy. It is mainly used to compress air and provide the power gas required for other production processes. A dryer is a mechanical device that absorbs moisture through desiccant particles and is used to dry airflow. Currently, air compressors are often equipped with dryers to dry the gas discharged from the air compressor, thus preventing the airflow containing moisture from entering downstream equipment and causing damage. However, in existing air compressor drying processes, because airflow continuously enters the dryer, the desiccant particles in the dryer become saturated after a period of time. This requires regular replacement of the desiccant particles, which makes the operation cumbersome, increases the burden on operators, and reduces operational efficiency. Utility Model Content

The positioning cover is installed inside the drying chamber. The positioning cover has an upper drying chamber and a lower drying chamber located inside, respectively. The upper perforated annular baffle is installed in the upper drying chamber, forming an upper loading chamber with the inner sides of the upper drying chamber.

The assembly includes an upper heating element, a perforated exhaust hood, a lower vent pipe, and a lower heating element. Multiple lower heating elements are evenly installed around the lower vent pipe, and the upper end of the lower vent pipe is connected to the perforated exhaust hood. Multiple upper heating elements are evenly installed around the upper end of the perforated exhaust hood. The air inlet pipe is installed in the middle of the bottom of the drying chamber and is telescopically connected to the lower vent pipe. A power motor is installed on the drying chamber and drives the ventilation and heating assembly to move up and down. When the perforated exhaust hood moves upward into the upper drying chamber, the multiple lower heating elements move upward into the lower drying chamber. When the perforated exhaust hood moves downward into the lower drying chamber, the multiple upper heating elements move downward into the lower drying chamber.

[0005] Furthermore, the positioning cover has a through plate in the middle, and an upper drying chamber and a lower drying chamber are distributed on the upper and lower sides of the through plate, respectively. A through channel is provided in the middle of the through plate, and an upper through opening and a lower through opening are respectively opened at the upper center and the lower center of the positioning cover. The ventilation heating component is movably connected between the upper through opening, the through channel, and the lower through opening.

[0006] Furthermore, the upper end of the porous exhaust hood is provided with a top column; the upper and lower ends of the top column are respectively provided with upper abutment rings and lower abutment rings, and multiple upper heating pipes are evenly installed around the area between the upper and lower abutment rings; the upper and lower ends of the lower vent pipe are respectively provided with upper docking rings and lower docking rings, and multiple lower heating pipes are evenly installed around the area between the upper and lower docking rings; when the porous exhaust hood moves upward into the upper drying chamber, the outer periphery of the lower abutment ring seals against the upper through-hole opening and the outer periphery of the upper docking ring seals against the through-channel; when the porous exhaust hood moves downward into the lower drying chamber, the outer periphery of the lower abutment ring seals against the through-channel and the upper docking ring seals against the lower through-hole opening.

[0007] Furthermore, the lower end of the lower vent pipe is provided with a telescopic tube; the lower end of the telescopic tube is connected to the upper end of the air inlet pipe.

[0008] Furthermore, lifting plates are provided on both sides of the lower vent pipe; lifting blocks are provided at the outer ends of the lifting plates; lifting slots are provided on both sides of the lower part of the drying chamber; a lifting block is slidably engaged in the lifting slot; a power motor is distributed on both sides of the lower part of the drying chamber; the lower side of the power motor is rotatably connected to the lifting slot through a lead screw; the lead screw is threadedly connected to the lifting block.

[0009] Furthermore, an upper exhaust hole is provided around the upper perimeter of the positioning cover, and an upper annular guide shroud is provided on the outer perimeter of the upper perimeter of the positioning cover; a lower exhaust hole is provided around the lower perimeter of the positioning cover, and a lower annular guide shroud is provided on the outer perimeter of the lower perimeter of the positioning cover.

[0012] Furthermore, the two sides of the positioning cover are fixedly installed inside the drying chamber by positioning posts.

[0013] The beneficial effects of this utility model are as follows: 1. In this invention, the airflow enters through the intake pipe, then passes through the telescopic pipe and the lower vent pipe, and exits from the periphery of the porous exhaust hood. The porous exhaust hood can thus move to either the upper or lower drying chamber for exhaust, achieving zoned exhaust. When the porous exhaust hood moves upward into the upper drying chamber, multiple lower heating pipes move upward into the lower drying chamber; when the porous exhaust hood moves downward into the lower drying chamber, multiple upper heating pipes move downward into the lower drying chamber. Thus, when the upper drying chamber is venting, the lower drying chamber is heating and dehumidifying, causing the desiccant particles in the lower drying chamber to regenerate. Conversely, when the lower drying chamber is venting, the upper drying chamber is heating and dehumidifying, causing the desiccant particles in the upper drying chamber to regenerate. This is achieved by periodically driving a power motor via an external controller, enabling automatic and flexible operation.

[0014] 2. When the upper drying chamber of this invention is ventilated for drying, the upper exhaust pipe is opened to discharge air, while the upper water vapor duct is closed to prevent airflow from escaping. At the same time, when the lower drying chamber is heated for drying and regenerating the desiccant particles inside, the lower exhaust pipe is closed, and the lower water vapor duct is opened to discharge water vapor. This allows for convenient and flexible control. Attached Figure Description

Multiple lower heating pipes 54 are evenly installed around the lower connecting ring 532.

When the porous exhaust hood 52 moves downward into the lower drying chamber 32, the outer periphery of the lower connecting ring 552 seals against the through-channel 351, and the upper connecting ring 531 seals against the lower through-hole 37. To ensure normal ventilation even when the ventilation heating assembly 5 moves up and down, a telescopic pipe 533 is provided at the lower end of the lower ventilation pipe 53; the lower end of the telescopic pipe 533 is connected to the upper end of the air inlet pipe 2.

[0024] like Figures 1 to 5 As shown, in order to facilitate the up-and-down lifting of the lower vent pipe 53, lifting plates 41 are provided on both sides of the lower vent pipe 53; lifting blocks 42 are provided at the outer ends of the lifting plates 41; lifting slots 11 are provided on both sides of the lower part of the drying chamber 1; a lifting block 42 is slidably engaged in the lifting slot 11; a power motor 4 is distributed on both sides of the lower part of the drying chamber 1; the lower side of the power motor 4 is rotatably connected to the lifting slot 11 through a lead screw 43; the lead screw 43 is threadedly connected to the lifting block 42.

[0025] like Figures 1 to 5As shown, to allow ventilation and moisture discharge in the upper drying chamber 31 and lower drying chamber 32, the positioning cover 3 has upper exhaust holes 12 around its upper perimeter, and an upper annular guide shroud 13 around its upper perimeter.

[0026] The airflow of this invention enters through the intake pipe 2, then passes through the telescopic pipe 533 and the lower vent pipe 53, and exits from the periphery of the porous exhaust hood 52.

Conversely, when the lower drying chamber 32 is venting, the upper drying chamber 31 is heated and dehumidified, causing the desiccant particles 8 within the upper drying chamber 31 to regenerate. This is achieved by periodically driving the power motor 4 via an external controller, enabling automatic and flexible operation.

[0027] When the upper drying chamber 31 of this invention is ventilated and dried, the upper exhaust pipe 17 is opened to discharge air, and the upper water vapor duct 131 is closed to prevent airflow from escaping. At the same time, when the lower drying chamber 32 is heated and dried to regenerate the desiccant particles inside, the lower exhaust pipe 18 is closed, and the lower water vapor duct 141 is opened to discharge water vapor. This allows for convenient and flexible control.
