Description

Technical Field

[0001] This utility model relates to the field of exhaust particulate matter capture technology, specifically a diesel generator exhaust particulate matter capture device. Background Technology

[0002] Particulate matter capture is a technology used to reduce particulate matter emissions from vehicle exhaust. This technology mainly uses specific equipment or systems to capture and remove solid particles and droplets from exhaust gases, thereby reducing the impact on the environment and human health.

[0003] Common particulate matter collection devices mainly use filter elements for collection. However, the filter elements are installed inside the housing and are usually difficult to remove. They can only be cleaned by heating and combustion, as well as by using a catalyst. Diesel generators are usually not equipped with corresponding heating structures. To clean the filter elements, the only way is to remove them. However, the generator must be stopped during the removal process, which cannot guarantee continuous operation of the generator.

A pair of mounting grooves are provided on the outer side of the core sleeve. The filter element is placed within the mounting grooves. An opening groove is provided at the position where the mounting shell aligns with the mounting grooves, and a sealing cap is installed within the opening groove. Rotating plates are rotatably connected to both ends of the core sleeve within the mounting shell, and guide holes are provided within the rotating plates.

[0006] Preferably, the guide hole has a funnel-shaped structure and is aligned with one of the mounting slot openings, and the rotating plate is close to the core sleeve on one side.

[0007] Preferably, a drive groove is provided on the periphery of the rotating plate, and a synchronous motor is installed on the outer side of the mounting housing at a position corresponding to the drive groove.

[0008] Preferably, the output end of the synchronous motor is located in the drive slot and a drive gear is fixed thereon. An annular toothed plate is fixed in the drive slot, and the drive gear meshes with the annular toothed plate.

[0009] Preferably, a fixing strip is fixed to the outside of the mounting housing and at both ends of the opening groove, and an arc-shaped plate is installed between the fixing strips, the arc-shaped plate being snapped onto the outer periphery of the sealing cover.

[0010] Preferably, the arc-shaped plate has plugs fixed at both ends. The plugs are T-shaped and are inserted into the fixing strip. Locking bolts are installed on the fixing strip at positions corresponding to the plugs.

[0011] Compared with the prior art, the beneficial effects of this utility model are: two alternately collecting filter elements are used to capture particulate matter inside the installation shell, and the exhaust gas can be diverted to different installation slots by rotating the rotating plate, so that the filter elements can be disassembled and cleaned without stopping the machine.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5This utility model provides a technical solution including a mounting shell 1 and a filter element 11. An air inlet pipe 2 is fixed at the front end of the mounting shell 1, and an exhaust pipe 3 is fixed at the end. A core sleeve 4 is fixed in the middle of the interior of the mounting shell 1. A pair of mounting grooves 41 are opened on the outer side of the core sleeve 4. The filter element 11 is placed in the mounting groove 41. An opening groove 13 is provided at the position where the mounting shell 1 is aligned with the mounting groove 41, and a sealing cover 12 is installed in the opening groove 13. Rotating plates 5 are rotatably connected to both ends of the core sleeve 4 inside the mounting shell 1. A guide hole 51 is opened in the rotating plate 5. The guide hole 51 is a funnel-shaped structure and is aligned with the opening of one of the mounting grooves 41. The side of the rotating plate 5 that is close to the core sleeve 4 is in contact with it.

[0020] A drive groove 52 is provided on the outer periphery of the rotating plate 5. A synchronous motor 6 is installed on the outer side of the mounting housing 1 at a position corresponding to the drive groove 52. The output end of the synchronous motor 6 is located in the drive groove 52 and a drive gear 61 is fixed thereon. An annular toothed plate 53 is fixed in the drive groove 52. The drive gear 61 meshes with the annular toothed plate 53.

[0021] A fixing strip 7 is fixed to the outside of the housing 1 and at both ends of the opening groove 13. An arc plate 71 is installed between the fixing strips 7. The arc plate 71 is snapped onto the outside of the sealing cover 12. A plug 72 is fixed to both ends of the arc plate 71. The plug 72 has a T-shaped structure and is inserted into the fixing strip 7. A locking bolt 73 is installed on the fixing strip 7 at the corresponding position of the plug 72.

[0022] Working principle: Driven by the synchronous motor 6, the drive gear 61 can be rotated. Then, through the transmission of the ring gear plate 53, the rotating plate 5 can be rotated, thus ensuring that the guide hole 51 is aligned with the opening of the different mounting slots 41. During air intake, the exhaust gas enters from the intake pipe 2 and enters the housing 1. After being guided by the guide hole 51, it passes through the designated filter element 11 for filtration. At this time, the other filter element 11 can be freely disassembled and installed, ensuring disassembly and cleaning during operation. During disassembly and installation, the locking bolt 73 can be released, and the connector 72 can be pulled horizontally from the fixing strip 7, thereby releasing the arc plate 71 from the locking of the sealing cover 12. After opening the sealing plate, the filter element 11 can be easily taken out through the opening slot 13.
