Description

Technical Field

[0001] This utility model relates to the field of filter technology, and more specifically, to a catalytic oil slurry tubular automatic backwashing filter device. Background Technology

[0002] Traditional backwash filters in existing technology use multiple sets of wedge-shaped wound filter elements. After a period of use, impurities adsorbed on the surface of the filter elements reach a certain amount, causing blockage and reducing flow rate. This requires manual intervention via the control system to force backwashing. If forced backwashing fails, it indicates that the filter elements are clogged, necessitating disassembly and manual cleaning. This shuts down the entire system, impacting the petrochemical company's oil pipeline operation. Furthermore, traditional backwash filters use external backwashing, increasing pipelines, equipment, and external flushing media, resulting in significant resource waste. Additionally, the cables in current filtration systems are mostly of fixed length, and their tangling can easily cause safety accidents. Therefore, a new type of catalytic slurry tubular automatic backwash filter is needed to solve these problems. Utility Model Content

Flanges 13 are fixedly installed on the inlet main pipe 9, the outlet main pipe 5 and the sewage discharge main pipe 11.

[0024] In this embodiment, the filtration device adopts dual control to blow the filter cake 14 into the bottom end cap of the container. The backwash adopts a three-short-one-long mode to blow down all the filter cakes 14. The whole process does not require backwashing with external media.

[0025] Example 2

[0026] refer to Figure 3 Example 2 is described below. This embodiment further describes Example 1 and includes a winding assembly 12. A connecting frame 15 is installed on the winding assembly 12. A motor 16 is fixedly installed on one side of the connecting frame 15, and a rotating rod 17 is installed at the output end of the motor 16. Four winding reels 18 are fixedly installed on the rotating rod 17. Cables 19 are wound on each of the four winding reels 18.

The backflushing process... Using a three-short-one-long pattern, all filter cakes 14 are blown off. The entire process requires no external media backwashing and no manual operation, with automatic rinsing, improving the practicality of the device. After backwashing, the slag discharge procedure begins. At this time, the valve of the lower sewage main pipe 11 is opened, and compressed air enters from the upper part of the container, mixing and discharging the residue at the bottom of the container into the sewage main pipe 11, and then discharging it into the external sludge tank 27.
