Description

Technical Field

[0001] This invention relates to the field of oil mesh dust filtration technology, and particularly to an oil mesh dust filter. Background Technology

[0002] An oil-mesh dust filter is an air filtration device made of multiple layers of corrugated metal mesh. The mesh is impregnated with a sticky oil and is mainly installed at the air inlet of ventilation systems in civil defense projects to filter dust, toxic fumes, and radioactive dust from the outside air, providing coarse filtration. The reason for using an oil-mesh filter is that when dust-laden airflow passes through the multiple layers of interlaced oil mesh, the airflow direction constantly changes. Dust, due to inertia, is thrown away from the airflow and adheres to the oil film, thus being effectively captured. At the same time, the oil can also trap and kill some bacteria. Furthermore, the device has low air resistance, is easy to clean and maintain, and is suitable for repeated use in high-dust environments such as protective ventilation systems.

[0003] Existing oil-mesh dust filters typically require oiling before installation and manual cleaning and oiling after a certain period of use, significantly reducing their continuous lifespan. While effective at filtering large and medium-sized dust particles, existing oil-mesh dust filters lack effective means of removing odors and most bacteria from the air. In current technology, some of the sterilizing or deodorizing filter media is blown away with the airflow, creating vacuum zones in the filter media chamber. Current technology cannot shield these vacuum zones, resulting in a significant reduction in sterilization or deodorization effectiveness. Therefore, a new type of oil-mesh dust filter is needed that facilitates filter cleaning and oiling, removes odors and most bacteria from the air, and automatically shields vacuum zones in the filter media chamber, thus addressing the shortcomings of existing oil-mesh dust filters. Summary of the Invention

[0013] The beneficial effects of the present invention compared with the prior art are: (1) The filtered oil in the dripping plate seeps out from the oil outlet below the dripping plate and then flows downward along the first and second inclined steel wires until it covers the first and second inclined steel wires, thereby realizing automatic oil replenishment of the filtered oil. When the first and second inclined steel wires need to be cleaned, the water pipe is connected to the connecting sleeve on the connecting device. Then the cleaning solvent in the water pipe will be sprayed onto the first and second inclined steel wires through the connecting pipe and the cleaning nozzle. Then the connecting sleeve and the connecting pipe are manually rotated. The connecting pipe drives the cleaning nozzle to swing, making the spraying of the cleaning solvent more uniform, thereby dissolving the filtered oil on the first and second inclined steel wires. (2) When large dust particles in the air are filtered by the filter oil on the oil filter device, medium-sized particles in the air will be intercepted by the first filter plate on the filter device, and then small particles in the air will be intercepted by the second filter plate on the filter device. The catalytic packing in the catalytic device will effectively remove odors and bacteria in the air, thereby achieving the interception of medium and small dust particles and the effective removal of odors and bacteria. (3) When the airflow passes through the catalytic packing in the catalytic device, the catalytic packing between the first and second partition plates will be carried away and consumed by the airflow. Then the remaining catalytic packing will be affected by gravity and accumulate downwards, so that the space above the first and second partition plates forms a vacuum zone. At this time, the spring and the counterweight will cause the limiting plate and the infusion plunger to slide downwards. The infusion plunger will drive the hydraulic oil in the infusion cylinder into the infusion shaft, and then through the infusion pipe, the inlet tank and the storage pipe into the seepage component and the storage cylinder. At this time, the weight of the hydraulic oil will drive the canvas rod to slide down, and the canvas rod will drive the canvas on the canvas roll to pull down, covering the vacuum zone.

[0040] Working principle of the invention: Figure 1 and Figure 2 The invention provides the usage methods and corresponding scenarios. The attitude control of the oil filter during the working process is determined by the oil filter device 3, the filtration device 4, and the catalytic device 5. The attitude of the oil filter device 3 is determined by the filtration device 4, and the attitude of the filtration device 4 is determined by the catalytic device 5. Therefore, the catalytic device 5 is the core of the oil filter during the working process.

[0041] Taking a preferred embodiment as an example, such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the filtered oil in the dripping plate 304 seeps downwards from the oil outlet below the dripping plate 304, and then flows diagonally downwards along the first inclined steel wire 302 and the second inclined steel wire 303 until it covers the first inclined steel wire 302 and the second inclined steel wire 303, thereby realizing automatic oil replenishment of the filtered oil. The lower part of the oil filter frame 301 prevents the filtered oil from dripping directly into the encapsulation shell 201 of the encapsulation device 2; the first encapsulation clamp 202 and the second encapsulation clamp 203 are used for the fixed installation of the oil filter frame 301 on the oil filter device 3; when the first inclined steel wire 302 and the second inclined steel wire 303 need to be cleaned, the water pipe is connected to the connecting device 1. The connecting sleeve 104 is connected, and then the cleaning solvent in the water pipe will be sprayed onto the first inclined steel wire 302 and the second inclined steel wire 303 through the connecting pipe 102 and the cleaning nozzle 103. Then, the connecting sleeve 104 and the connecting pipe 102 are manually rotated, and the connecting pipe 102 drives the cleaning nozzle 103 to swing, so that the spraying of the cleaning solvent is more uniform, thereby dissolving the filter oil on the first inclined steel wire 302 and the second inclined steel wire 303. The connecting interface 101 is used for air intake and exhaust. The duckbill nozzle 106 at the outlet of the column nozzle 105 is used to convert the water column into a water curtain, thereby expanding the spraying range of the cleaning solvent.

[0042] like Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14As shown, when large dust particles in the air are filtered by the filter oil on the oil filter device 3, medium-sized particles in the air are intercepted by the first filter plate 402 on the filter device 4, and small particles in the air are intercepted by the second filter plate 404 on the filter device 4. The catalytic packing in the catalytic device 5 effectively removes odors and bacteria in the air, thereby achieving the interception of medium and small dust particles and the effective removal of odors and bacteria. When the airflow passes through the catalytic packing in the catalytic device 5, the catalytic packing between the first partition plate 502 and the second partition plate 504 is carried away and consumed by the airflow. Subsequently, the remaining catalytic packing is affected by gravity and accumulates downward, so that the space above the first partition plate 502 and the second partition plate 504 forms a vacuum zone. At this time, the spring and the counterweight will cause the limiting plate 505 and the infusion plunger 507 to slide downward. The infusion plunger 507 drives the hydraulic oil in the infusion cylinder 508 into the infusion shaft 506, and then through the infusion... Pipe 501, inlet tank 403, and storage pipe 409 enter the seepage assembly 407 and storage cylinder 408. At this time, the weight of the hydraulic oil will cause the canvas rod 406 to slide down, and the canvas rod 406 will cause the canvas on the canvas roll 405 to pull down, covering the vacuum area. The filter frame 401 is used to support the first filter plate 402 and the second filter plate 404. When the hydraulic oil enters the seepage cylinder 410 on the seepage assembly 407, the hydraulic oil will enter through the transverse through hole 414. When the hydraulic oil is introduced into the seepage cylinder 411, and the weight of the hydraulic oil in the seepage cylinder 411 reaches a certain level, the hydraulic oil drives the seepage plug 412 and the seepage main shaft 413 to slide downward in the seepage hole 417, so that the seepage plug 412 is pulled out from the seepage hole 417, and then the hydraulic oil flows downward from the seepage hole 417 into the reservoir 408; when the seepage main shaft 413 slides downward, the seepage main shaft 413 will also drive the pressure column 415 to press down, and the pressure column 415 drives the elastic pad 416 to compress downward.

[0043] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
