Description

Technical Field

[0001] The invention relates to the technical field of generator air filters, and in particular to an air filter for a military diesel generator. Background Art

[0002] Military diesel generators are portable or fixed power generation equipment designed to meet the power needs of military equipment and facilities. These generators usually have high reliability, durability and the ability to operate in harsh environments. The air filter of a military diesel generator is a key component, which is responsible for filtering dust and other tiny particles in the air entering the engine to prevent these impurities from damaging the precision parts inside the engine. The air filter is essential to ensure the reliable operation of the engine and extend its service life.

[0003] In the prior art, the air filter of a diesel generator usually adopts a fixed design. The replacement of the filter element requires the disassembly of multiple parts, which is cumbersome and time-consuming. In addition, the traditional air filter cannot adjust the filtering effect according to demand during the startup and operation of the generator, which easily leads to unstable air intake efficiency. At the same time, when the generator is undersupplied with air, there is a lack of an effective auxiliary air supply mechanism, which affects the stable performance of the generator.

[0004] Therefore, a kind of air filter for military diesel generator is needed. Summary of the invention

[0005] The purpose of the present invention is to provide an air filter for a military diesel generator to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an air filter for a military diesel generator, comprising an air filter body, the bottom end of the air filter body is connected to an air intake connecting pipe, an air intake filtering mechanism is installed above the air filter body, a splicing mechanism is installed on the inner side of the air filter body, and an air intake auxiliary mechanism is arranged on the outer side of the air filter body.

[0007] As a further improvement of the present technical solution: the air intake filter mechanism includes a mounting ring, a filter element, a mounting slot, a mounting base, a fine-pore filter element, a coarse-pore filter element, a rotating adjustment tube and an opening and closing sealing plate, a mounting ring is installed on the top of the air filter body, a filter element is installed on the inner side of the mounting ring, a mounting slot is provided on the inner surface of the mounting ring, and a mounting base is provided on the outer surface of the filter element.

[0008] As a further improvement of the technical solution: a fine-pore filter element is installed on the left side of the interior of the filter element, and a coarse-pore filter element is installed on the right side of the interior of the filter element.

[0009] As a further improvement of the technical solution: the top end of the mounting ring is rotatably connected with a rotating adjustment tube, the inner bottom end of the rotating adjustment tube is installed with an opening and closing sealing plate, and the opening and closing sealing plate is fitted with the top end of the filter element.

[0010] As a further improvement of the present technical solution: the splicing mechanism includes a splicing interface, a splicing foot, a fixed clamping platform, a spring push rod, a fixed top plate, a sealing groove and a sealing ring. The surface of the air filter body is provided with a splicing interface, the outer side of the bottom end of the mounting ring is fixedly connected with a splicing foot, and the inner side of the splicing interface is provided with a fixed clamping platform.

[0011] As a further improvement of the technical solution: a spring top rod is installed at the inner bottom end of the splicing interface, and a fixed top plate is fixedly connected to the top end of the spring top rod.

[0012] As a further improvement of the technical solution: a sealing groove is provided on the inner side of the air filter body, and a sealing ring is provided on the inner side of the bottom end of the mounting ring.

[0013] As a further improvement of the present technical solution: the air intake auxiliary mechanism includes a connecting side platform, an auxiliary pipe, an air intake opening and closing flap, a lateral air inlet, a protective net and a dust filter net, a connecting side platform is arranged on the outside of the air filter body, an auxiliary pipe is installed inside the connecting side platform, an air intake opening and closing flap is arranged on the inside of the auxiliary pipe, and a lateral air inlet is opened below the connecting side platform.

[0014] As a further improvement of the technical solution: three groups of the air intake opening and closing flaps are provided, and the air intake opening and closing flaps are made of rubber material.

[0015] As a further improvement of the technical solution: a protective net is arranged above the auxiliary pipe, and a dust filter net is arranged below the auxiliary pipe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] An air filter for a military diesel generator is provided with an air intake filtering mechanism and a splicing mechanism. The splicing clamping foot is separated from the fixed clamping platform by pressing the mounting ring downward, and then the mounting ring can be rotated to disassemble it, thereby greatly improving the convenience of replacing and installing the filter element. At the same time, the sealing ring is clamped into the sealing groove to seal the air filter body to prevent air from entering from the connection of the mounting ring. Different fine-pore filter elements and coarse-pore filter elements are provided to use different filters at different stages of the generator. For example, when a larger air intake volume is required when the generator is just started, a coarse-pore filter element is used to filter the air to reduce a certain filtering effect and provide a better air intake effect. After the engine runs smoothly, a fine-pore filter element is used to filter the air to ensure smooth air intake while improving a better filtering effect.

[0018] By setting up an air intake auxiliary mechanism, when the generator is short of air supply, negative pressure will be generated inside it, causing the air intake opening and closing flap to be sucked inward by the negative pressure, so that the air intake opening and closing flap will open, providing additional air supply to the generator to ensure the stability of the generator. At the same time, the rubber material has good resilience. After the air supply inside the generator is normal, it can rebound by itself to close the air intake opening and closing flap. At the same time, by setting up multiple sets of air intake opening and closing flaps, the air intake opening and closing flaps can be prevented from being abnormally opened due to loose air intake opening and closing flaps or internal air supply fluctuations. Finally, the air intake of the auxiliary pipe is filtered to a certain extent through the protective net and the dust filter net to prevent dust from directly entering the generator through the auxiliary pipe.

[0031] See also Figure 1-8 The present invention provides a technical solution: an air filter for a military diesel generator, comprising an air filter body 1, the bottom end of the air filter body 1 is connected to an air intake connecting pipe 2, an air intake filtering mechanism 3 is installed above the air filter body 1, a splicing mechanism 4 is installed on the inner side of the air filter body 1, and an air intake auxiliary mechanism 5 is arranged on the outer side of the air filter body 1.

[0032] Specifically, the air intake filter mechanism 3 includes a mounting ring 301, a filter element 302, a mounting slot 303, a mounting platform 304, a fine-pore filter element 305, a coarse-pore filter element 306, a rotating adjustment tube 307 and an opening and closing sealing plate 308. The mounting ring 301 is installed on the top of the air filter body 1, the filter element 302 is installed on the inner side of the mounting ring 301, the inner surface of the mounting ring 301 is provided with a mounting slot 303, and the outer surface of the filter element 302 is provided with a mounting platform 304. The device is installed on the air intake connecting pipe 2. When the generator is in use, the air is filtered by the filter element 302 to ensure the normal use of the generator.

[0033] Specifically, a fine-pore filter element 305 is installed on the left side of the interior of the filter element 302, and a coarse-pore filter element 306 is installed on the right side of the interior of the filter element 302. By setting different fine-pore filter elements 305 and coarse-pore filter elements 306, different filters are used in different stages of the generator. For example, when a larger air intake is required when the generator is just started, the coarse-pore filter element 306 is used to filter the air, reducing a certain filtering effect and providing a better air intake effect. After the engine runs smoothly, the fine-pore filter element 305 is used to filter the air to ensure smooth air intake while improving better filtering effects.

[0034] Specifically, the top end of the mounting ring 301 is rotatably connected to a rotating adjustment tube 307, and an opening and closing sealing plate 308 is installed at the inner bottom end of the rotating adjustment tube 307. The opening and closing sealing plate 308 fits with the top end of the filter element 302. By rotating the rotating adjustment tube 307, the opening and closing sealing plate 308 separates and seals the filter element 302, thereby increasing the convenience of adjusting the coarse-pore filter element 306 and the fine-pore filter element 305.

[0035] Specifically, the splicing mechanism 4 includes a splicing interface 401, a splicing foot 402, a fixed clamping platform 403, a spring top rod 404, a fixed top plate 405, a sealing groove 406 and a sealing ring 407.

The splicing foot 402 is inserted into the inner side of the splicing interface 401, and then the mounting ring 301 is rotated to make the splicing foot 402 clamped in the fixed clamping platform 403, so as to fix the mounting ring 301.

[0036] Specifically, a spring top rod 404 is installed at the bottom inner end of the splicing interface 401, and a fixed top plate 405 is fixedly connected to the top of the spring top rod 404. The spring top rod 404 drives the fixed top plate 405 to support the splicing pin 402 upward to prevent the splicing pin 402 from falling off from the splicing interface 401, thereby improving the stability of the installation of the mounting ring 301. In this way, the mounting ring 301 only needs to be pressed downward to make the splicing pin 402 separate from the fixed clamping platform 403, and then the mounting ring 301 can be rotated to disassemble it, which greatly improves the convenience of replacing and installing the filter element 302.

[0037] Specifically, a sealing groove 406 is opened on the inner side of the air filter body 1, and a sealing ring 407 is arranged on the inner side of the bottom end of the mounting ring 301. The sealing ring 407 is inserted into the sealing groove 406 to seal the air filter body 1, thereby preventing air from entering from the connection of the mounting ring 301 and ensuring the filtering effect of the air.

[0038] Specifically, the air intake auxiliary mechanism 5 includes a connecting side platform 501, an auxiliary pipe 502, an air intake opening and closing flap 503, a lateral air inlet 504, a protective net 505 and a dust filter net 506.

When the generator is short of air supply, negative pressure will be generated inside, so that the air intake opening and closing flap 503 is subjected to inward negative pressure suction, so that the air intake opening and closing flap 503 will open, and additional air supply will be provided to the generator, thereby ensuring the stability of the generator.

[0039] Specifically, three groups of air intake opening and closing flaps 503 are provided. The air intake opening and closing flaps 503 are made of rubber material. The rubber material has good resilience. After the air supply inside the generator is normal, the rubber material can rebound by itself to close the air intake opening and closing flaps 503. At the same time, by providing multiple groups of air intake opening and closing flaps 503, the air intake opening and closing flaps 503 can be prevented from being abnormally opened due to looseness of the air intake opening and closing flaps 503 or fluctuations in the internal air supply.

[0040] Specifically, a protective net 505 is provided above the auxiliary pipe 502, and a dust filter net 506 is provided below the auxiliary pipe 502.

At the same time, insert the sealing ring 407 into the sealing groove 406 to seal the air filter body 1 to prevent air from entering from the connection of the mounting ring 301. When the generator is in use, the air is filtered through the filter element 302, and then the opening and closing sealing plate 308 is rotated to separate and seal the filter element 302 by rotating the adjusting tube 307, and the coarse-pore filter element 306 and the fine-pore filter element 305 are adjusted, so as to set different fine-pore filter elements 3 05 and coarse-pore filter element 306, use different filtration at different stages of the generator, such as: when the generator is just started and needs a larger intake volume, use the coarse-pore filter element 306 to filter the air, reduce a certain filtering effect, and provide a better intake effect. After the engine runs smoothly, use the fine-pore filter element 305 to filter the air, ensure smooth intake and improve better filtering effect. When the generator is short of air supply, negative pressure will be generated inside, so that the intake opening and closing flap 503 is subjected to the inward negative pressure suction, so that the intake opening and closing flap 503 will It will open to provide additional air supply to the generator to ensure the stability of the generator. At the same time, the rubber material has good resilience. After the air supply inside the generator is normal, it can rebound by itself to close the air intake opening and closing flap 503. At the same time, by setting up multiple sets of air intake opening and closing flaps 503, the air intake opening and closing flap 503 can be prevented from being abnormally opened due to looseness of the air intake opening and closing flap 503 or fluctuations in the internal air supply. Finally, the air intake of the auxiliary pipe 502 is filtered through the protective net 505 and the dust filter net 506 to prevent dust from directly entering the generator through the auxiliary pipe 502.
