[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1-3 This utility model provides a technical solution: a tubular filtration device, including a filter cylinder 1, a detachable top cover 4 installed on the upper end of the filter cylinder 1, that is, a connecting ring is sleeved on the upper end of the filter cylinder 1 and fixed to the filter cylinder 1, the connecting ring is connected to the top cover 4 by multiple sets of fasteners, a sealing ring is installed between the connecting ring and the top cover 4, and a handle is installed in the middle of the upper surface of the top cover 4. The handle has a U-shaped structure and provides a gripping carrier for moving the position of the top cover 4.

[0023] See Figure 3The filter cartridge 1 is equipped with a filter element 17. The upper end of the filter element 17 is installed between the filter cartridge 1 and the top cover 4. The lower end of the filter cartridge 1 is equipped with an inlet pipe 12 and an outlet pipe 6. The end of the inlet pipe 12 located outside the filter cartridge 1 is equipped with a first flange, and the end of the outlet pipe 6 located away from the filter cartridge 1 is equipped with a second flange. The upper end of the inlet pipe 12 extends to the upper part of the filter element 17 and the upper end of the inlet pipe 12 communicates with the internal space of the filter element 17. Fluid flows into the filter element 17 through the inlet pipe 12. After the filter element 17 filters the fluid, the filtered fluid is discharged through the outlet pipe 6.

[0024] See Figure 4 The filter cylinder 1 has three vertical rods 11 installed in a ring at equal intervals at its lower end. The lower end of the filter cylinder 1 is connected and fixed with a ring 16. The upper surface of the ring 16 has small holes at equal intervals in a ring. The upper end of the vertical rod 11 is connected and fixed with a stud head 21. After the upper end of the stud head 21 passes through the small hole, the second nut 20 is screwed on to complete the assembly of the vertical rod 11 and the filter cylinder 1.

[0025] See Figures 1-4 A horizontal plate 10 is fixedly connected to the lower end of the vertical rod 11. A circular bottom groove 8 is provided directly above the filter cylinder 1. The end of the inlet pipe 12 located outside the filter cylinder 1 and the end of the outlet pipe 6 located away from the filter cylinder 1 are both located directly above the circular bottom groove 8. Multiple thick rods 13 are fixedly fixed in a ring at equal intervals at the bottom of the circular bottom groove 8. Threaded heads 15 are fixedly connected to the upper ends of the thick rods 13. A vertical hole 19 is opened at the end of the horizontal plate 10 away from the vertical rod 11. The threaded head 15 passes through the vertical hole 19 and is threadedly connected to a first nut 14. The first nut 14 is located on the upper side of the vertical hole 19. A pipe connector 9 for connecting the inlet and outlet pipes is installed at the lower part of the outer surface of the circular bottom groove 8. Sampling valves 7 are installed on the outer surfaces of both the inlet pipe 12 and the outlet pipe 6. Pressure gauges 5 are installed on the upper part of the outer surface of the inlet and outlet pipes 6. The sampling valve 7 is located directly above the round bottom groove 8. After the three threaded heads 15 pass through the vertical holes 19 on the three horizontal plates 10, the first nut 14 is screwed on to complete the assembly of the round bottom groove 8 and the filter cylinder 1. At this time, the sampling valve 7, the end of the outlet pipe 6 away from the filter cylinder 1 and the end of the inlet pipe 12 outside the filter cylinder 1 are all directly above the round bottom groove 8. Therefore, when leakage occurs due to seal failure, the fluid leaking from the sampling valve 7, the outlet pipe 6 or the end of the inlet pipe 12 flows into the round bottom groove 8 and is then drained into the collection container through the drain pipe connected to the pipe joint 9, so as to drain the fluid dripping due to seal failure and prevent the leaked fluid from flowing freely.

[0026] See Figures 1-5The bottom of the circular bottom groove 8 has multiple bottom holes 22 equidistantly spaced in an annular shape. The lower surface of the thick rod 13 has an insertion hole 18 aligned with the bottom holes 22. The inner diameter of the insertion hole 18 is the same as the inner diameter of the bottom holes 22. The threaded head 15 is threaded with an internal threaded tube 2. The upper end of the internal threaded tube 2 is fitted with a plug rod 3 that mates with the insertion hole 18. The upper end of the plug rod 3 is higher than the height of the top cover 4. The diameter of the plug rod 3 is the same as the inner diameter of the insertion hole 18, so that the internal threaded tube 2 is threadedly connected to the threaded head 15. At this time, the plug rod 3 is higher than the top cover 4, so that the three plug rods 3 in the lower circular bottom groove 8 are respectively inserted into the channel formed by the insertion hole 18 and the bottom hole 22 in the upper circular bottom groove 8, realizing the assembly of two adjacent circular bottom grooves 8, that is, completing the stacking of two adjacent filter cylinders 1. This process is repeated to facilitate the storage of more filter cylinders 1 in a unit area, thus making full use of the storage space.
