However, due to the corrosive nature of the system, traditional capture or filtration methods are extremely costly. Therefore, effective particulate capture technology in corrosive environments is crucial for the stable operation of vacuum systems.
[0003] Solid particulate matter entering a vacuum system can cause numerous problems. First, acting as an abrasive, particulate matter accelerates wear on components within the pump chamber, leading to damage to the pump rotor and chamber, and even clogging oil passages, rendering the pump malfunction. Second, particulate matter entering vacuum valves can cause seal failure, resulting in leaks and affecting the system's vacuum level. Therefore, filtering solid particulate matter is a crucial measure for extending the service life of vacuum systems and improving production efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Example:
[0027] Reference Figure 1-5 A corrosion-resistant vacuum pipeline solid particulate matter capture device includes a connecting pipe 1 and a connecting pipe 2, which are connected by a flange. It also includes: a filter cartridge 201 connected inside the connecting pipe 2, with the filter cartridge 201 located inside the connecting pipe 1; a paddle 301 rotatably connected to the air inlet end of the connecting pipe 1, with a rotating shaft 302 fixedly connected to the paddle 301; multiple sets of connecting rods 304 fixedly connected to the rotating shaft 302, with scrapers 305 fixedly connected to the connecting rods 304, the scrapers 305 being in contact with the surface of the filter cartridge 201; a pipe opening provided on the connecting pipe 1, with a pressure gauge 101 installed on the pipe opening; and the rotating shaft 302 penetrating the filter cartridge 201, with a fixed... Multiple sets of jet rods 307 are connected, and multiple sets of jet nozzles 308 are provided on the jet rods 307. A cam 303 is fixedly connected to the rotating shaft 302. A piston cylinder 4 is fixedly connected to the connecting pipe 1. The telescopic end of the piston cylinder 4 abuts against the cam 303. An exhaust pipe 401 is connected to the exhaust end of the piston cylinder 4. The exhaust pipe 401 communicates with the jet nozzles 308. A threaded groove is provided on the rotating shaft 302. An extension pipe 306 is threadedly connected to the threaded groove. The jet rod 307 is fixedly connected to the extension pipe 306. A rotary connector 5 is fixedly connected to the rotating shaft 302. The exhaust pipe 401 is connected to the rotary connector 5. A sealing ring is sleeved on the through end of the rotating shaft 302. An extension pipe 309 is fixedly connected to the extension pipe 306.
[0028] Depending on the process environment, different materials can be selected for connecting pipe 1 and connecting pipe 2. In corrosive environments with a pH value of 2-7 and mainly containing chloride ions, 2207 / 2507 duplex steel can be selected; in corrosive environments with a pH value less than 2, HC276 / HC22 Hastelloy alloy can be selected.
[0029] The intake end of piston cylinder 4 is equipped with a filter screen, or it is directly connected to clean gas to prevent impurities from being discharged through the exhaust pipe 401.
[0030] In actual use, connecting pipe 1 and connecting pipe 2 are connected by flange ring. Connecting pipe 2 is connected to the vacuum system, and connecting pipe 1 is connected to the exhaust end of the gas to be filtered. At this time, the entry of gas will cause the blade 301 to rotate, and then the gas will pass through the filter cartridge 201. Under the filtration of the filter cartridge 201, the gas is filtered, particulate impurities will be intercepted, and clean gas will pass directly and finally enter the vacuum system.
[0031] As the blade 301 rotates, the connecting rod 304 and the scraper 305 also rotate, thereby cleaning the surface of the filter cartridge 201 through the scraper 305, reducing the accumulation of impurities that affect the air output of the filter cartridge 201.
[0032] Simultaneously, as the cam 303 rotates, it will squeeze the telescopic end of the piston cylinder 4, thereby drawing in external gas through the piston cylinder 4. At this time, the inner wall of the filter cartridge 201 can be back-blown through the continuously rotating jet nozzle 308, thereby achieving back-blowing cleaning.
[0033] It should be noted that in this embodiment, the piston cylinder 4 is placed outside the connecting pipe 1, and the piston cylinder 4 passes through the connecting pipe 1. It only needs to be sealed by a rubber ring. Alternatively, it can be installed inside. The specific configuration depends on the requirements.
[0034] Specifically, extension pipe 309 is used to assist in the installation and disassembly of extension pipe 306.
[0035] When the pressure gauge 101 reading rises, the filter cartridge 201 needs to be disassembled, replaced, or cleaned. After replacement or cleaning, it should be reinstalled and put into use.
[0036] This invention can effectively filter solid particles in gas, reducing the amount of solids entering the vacuum system. At the same time, the arrangement of the paddle 301 and piston cylinder 4 can clean the filter cartridge 201, increasing the service life of the filter cartridge 201 and facilitating long-term use.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
