[0020] Example

[0021] See also Figure 1-Figure 6The utility model is a drying filter with gas-liquid separation, comprising a lower cylinder 1, a middle cylinder 8 and an upper cylinder cover 13. An air inlet pipe 2 is connected to the lower outer wall of the front side of the lower cylinder 1. The bottom of the lower cylinder 1 is bucket-shaped, and a drain pipe 3 is connected to the bottom of the lower cylinder 1.

An upper external thread is provided on the outer wall above the middle cylinder 8. 10, four groups of supporting plates 11 are fixedly arranged in an annular manner at equal intervals below the inner wall of the middle cylinder 8, a cylindrical filter element 12 is clamped inside the middle cylinder 8, a desiccant is installed inside the cylindrical filter element 12, the bottom end of the cylindrical filter element 12 is against the top of the four groups of supporting plates 11, the top of the upper cylinder cover 13 is in the shape of an inverted bucket, the top of the upper cylinder cover 13 is connected with an air outlet pipe 14, an upper internal thread 15 is arranged on the inner wall of the circumference of the upper cylinder cover 13, and the upper cylinder cover 13 is threadedly mounted on the middle cylinder 8 through the matching screw thread 15 and the upper external thread 10; when in use, the gas enters the lower cylinder 1 through the air inlet pipe 2, the gas is guided by the spiral spoiler 4 and spirally rises along the spiral spoiler 4, the droplets entrained in the gas hit and adhere to the surface of the spiral spoiler 4, and then gradually condense The liquid droplets are formed into large droplets. When they reach a certain level, they slide down along the surface of the spiral spoiler 4 and are discharged through the drain pipe 3. The rising airflow guided by the spiral spoiler 4 hits the baffle plate 5 again, and the staggered arrangement of the baffle plate 5 changes the movement direction of the airflow for many times. In this process, the droplets entrained in the airflow hit and adhere to the lower surface of the baffle plate 5, and then gradually condense into large droplets. When they reach a certain level, they slide down or drip onto the spiral spoiler 4 along the surface of the baffle plate 5 and are discharged through the drain pipe 3, thereby realizing the secondary separation of gas and liquid. After the secondary separation of gas and liquid, the gas continues to rise and enters the middle cylinder 8 from the lower cylinder 1, and is filtered by the cylindrical filter element 12. The desiccant in the cylindrical filter element 12 filters the gas. The droplets in the filter are further absorbed to achieve drying of the gas. The dried gas passes through the cylindrical filter element 12 and enters the upper cylinder cover 13, and is discharged through the air outlet pipe 14, so that it is easy to separate the gas and liquid and increase the service life of the desiccant. When it is necessary to clean the interior or replace the desiccant, the upper cylinder cover 13 can be removed from the middle cylinder body 8, the cylindrical filter element 12 can be taken out, the desiccant can be poured out for replacement, and the cylindrical filter element 12 can be cleaned, and then the middle cylinder body 8 can be removed from the docking expansion 6, and the interior of the lower cylinder body 1 can be cleaned. The filter is composed of three parts screw-mounted, which can be cleaned separately by disassembly and assembly. Compared with the traditional one-piece structure, it is convenient for internal cleaning and replacement of desiccant, and improves practicality.

A blocking net 20 is provided at the bottom of the inner wall of the T-shaped pressure ring 16. By setting the T-shaped pressure ring 16, after the cylindrical filter element 12 is installed, the T-shaped pressure ring 16 can be clamped to the top of the middle cylinder 8, so that the bottom end of the T-shaped pressure ring 16 abuts against the top of the cylindrical filter element 12, and then the upper cylinder cover 13 is screwed onto the middle cylinder 8, so that the inner wall of the conical surface of the upper cylinder cover 13 is pressed against the top of the T-shaped pressure ring 16, so that the cylindrical filter element 12 can be placed stably through the clamping effect of the T-shaped pressure ring 16 and the supporting plate 11 to prevent the cylindrical filter element 12 from moving up and down, and the blocking net 20 can prevent the desiccant from flowing out from above the cylindrical filter element 12.

[0023] The outer circumferential walls of the butt expansion opening 6 and the upper cylinder cover 13 are both fixedly sleeved with anti-skid rubber sleeves 17 ; the anti-skid rubber sleeves 17 can prevent hands from slipping when screwing down the cylinder body 1 and the upper cylinder cover 13 .

[0024] An annular sealing gasket 18 is placed inside the docking flare 6 at the bottom end of the docking internal thread 7; by providing the annular sealing gasket 18, the sealing performance when the middle cylinder 8 and the docking flare 6 are docked can be improved.

[0026] The utility model is a drying filter with gas-liquid separation, and its working principle is that when in use, the gas enters the lower cylinder 1 through the air inlet pipe 2, and the gas is guided by the spiral spoiler 4 and spirally rises along the spiral spoiler 4, and the liquid droplets entrained in the gas hit and adhere to the surface of the spiral spoiler 4, and then gradually condense into large droplets, and after reaching a certain degree, they slide along the surface of the spiral spoiler 4 and are discharged through the liquid discharge pipe 3, and the rising airflow guided by the spiral spoiler 4 hits the baffle plate 5 again, and the staggered arrangement of the baffle plate 5 changes the movement direction of the airflow for many times. In this process, the liquid droplets entrained in the airflow hit and adhere to the lower surface of the baffle plate 5, and then gradually condense into large droplets, and after reaching a certain degree, they slide or drip along the surface of the baffle plate 5 onto the spiral spoiler 4 and are discharged through the liquid discharge pipe 3. The liquid is discharged through the drain pipe 3, thereby realizing the secondary separation of gas and liquid. The gas after the secondary separation of gas and liquid continues to rise and enters the middle cylinder 8 from the lower cylinder 1, and is filtered by the cylindrical filter element 12. The desiccant in the cylindrical filter element 12 further absorbs the liquid droplets in the gas to realize the drying of the gas. The dried gas passes through the cylindrical filter element 12 and enters the upper cylinder cover 13, and is discharged through the air outlet pipe 14, so that it is easy to separate the gas and liquid and improve the service life of the desiccant.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
