Description

Technical Field

[0001] This utility model relates to the field of mining diesel engine technology, specifically a dry exhaust gas purifier for mining diesel engines with self-cleaning function. Background Technology

[0002] Mining diesel engines are diesel power equipment designed specifically for mining environments. Their core function is to provide power for underground mining equipment, transport vehicles, and generator sets. Mining diesel engine dry exhaust gas purifiers are exhaust gas treatment equipment designed specifically for mining environments. They remove particulate matter, black smoke, and harmful gases from diesel engine exhaust gas through physical interception or catalytic oxidation technology.

[0003] Currently, some particulate matter filters used in mining diesel engines can not only intercept carbon particles in the exhaust gas, but also support high-temperature regeneration. High-temperature regeneration is used to reduce the clogging of the particulate matter filter and achieve self-cleaning. The particulate matter is treated at high temperature to form ash. During this process, some particulate matter will be discharged with the exhaust gas and pollute the environment, which can affect the overall purification effect of the exhaust gas purifier. Utility Model Content

The pull rope 320c is disposed inside the exhaust pipe 200. One end of 20c is connected to the rectangular component 320a, and the other end is equipped with a force-bearing component 320f. The airflow generated by the exhaust gas acts on the force-bearing component 320f, and then the force-bearing component 320f and the pull rope 320c drive the rectangular component 320a and the cleaning component 320b to move, adjusting the rectangular component 320a and the cleaning component 320b to a high position for subsequent cleaning. The pull rope 320c has a reinforcing component 320e embedded inside to reinforce the force-bearing component 320f. The extension component 320d is fused to the rectangular component 320a, and at least two of them are provided. The bottom of the extension component 320d is provided with an inclined surface. The limiting part 330 includes a part installed on the surface of the filter plate 310 and in contact with the rectangular component 320a.

The guide part 340 includes at least two guide rollers 340a with a height difference and a reinforcement part 340b installed inside the exhaust pipe 200. The guide rollers 340a are installed inside the exhaust pipe 200 to improve the smoothness of the movement of the pull rope 320c. The surface of the pull rope 320c contacts the surface of the guide rollers 340a. The pull rope 320c passes through the reinforcement part 340b.

[0019] The collection unit 400 includes a hollow box 410 installed inside the exhaust pipe 200 and placed on one side of the filter plate 310, a connector 420 bolted to the surface of the exhaust pipe 200 for sealing the bottom of the hollow box 410, and a blocking part 430 that moves inside the hollow box 410. The top of the hollow box 410 has a notch for receiving ash. When the cleaning unit 320 cleans the filter plate 310, the blocking part 430 moves under force, releasing the seal on the notch. The blocking part 430 includes a cover plate 430a disposed inside the hollow box 410 for blocking the notch, a movable part 430b penetrating the hollow box 410 and connected to the cover plate 430a, and a pull rope 430c penetrating the filter plate 310 with one end fixed to the surface of the cover plate 430a. The top of the movable part 430b is designed to be inclined and connected to the extension part... Corresponding to the inclined surface of 320d, a counterweight 430d is installed at one end of the pull rope 430c. By gravity, the pull rope 430c automatically resets and covers the top of the hollow box 410. Protective parts 440 are welded to both sides of the inner wall of the exhaust pipe 200. The interior of the protective part 440 is provided with a rotating shaft 450 for guiding the covering part 430. There are at least four rotating shafts 450. The extension 320d descends, and its inclined surface contacts the top of the moving part 430b and squeezes the moving part 430b, causing the moving part 430b to move. At this time, the cover plate 430a moves, and the gap is exposed. The ash cleaned from the surface of the filter plate 310 can be discharged into the hollow box 410. Afterwards, under the action of the gravity of the counterweight 430d, the cover plate 430a moves and resets to cover the gap again.

[0020] Working principle: Exhaust gas is filtered through the particulate matter trap body 100 and discharged into the exhaust pipe 200. When blockage occurs, the particulate matter trap body 100 automatically regenerates, treating the blocked particles with high temperature. The ash generated after treatment is discharged into the exhaust pipe 200 along with the exhaust gas. The exhaust gas drives airflow and pulls the force-bearing component 320f, causing the pull rope 320c to lift the rectangular component 320a and the cleaning component 320b. The exhaust gas carrying the ash is purified by passing through the filter plate 310. Ash remains on the surface of filter plate 310. After the exhaust gas is discharged, the gas flow rate discharged from the particulate matter trap body 100 to the exhaust pipe 200 decreases. At the same time, the cleaning part 320 moves downward under the action of gravity and scrapes off the ash on the surface of filter plate 310. The extension 320d descends and can squeeze the moving part 430b, causing the cover plate 430a to move. The top notch of the hollow box 410 is exposed, and some ash can be discharged into the interior of the hollow box 410 with slight air flow. The staff regularly removes the connector 420 and cleans the dust inside the hollow box 410.
