Description

Technical Field

[0001] The invention relates to the technical field of compressor accessories, in particular to an air filter element for a compressor. Background Art

[0002] The function of the air compressor filter element is to allow the oil-containing compressed air generated by the main engine to enter the cooler, and then enter the oil-gas filter element for filtration after mechanical separation, intercept and aggregate the oil mist in the gas, forming oil droplets concentrated at the bottom of the filter element and returned to the compressor lubrication system through the oil return pipe, so that the compressor can discharge purer and higher-quality compressed air; in short, it is a device that removes solid dust, oil and gas particles and liquid substances in the compressed air.

[0003] In the past, when the oil-containing compressed air generated by the compressor entered the filter element for filtration, the oil and gas would be intercepted and aggregated on the filter element to form oil droplets that flow to the bottom of the filter element. However, the normal flow speed of the oil droplets is slow, and under the action of the gas, the oil droplets are easily retained on the filter holes, making it difficult for the gas to pass through, and the use effect is not ideal.

[0004] Therefore, a compressor air filter element is proposed. Summary of the invention

[0008] It is characterized by: also including:

[0009] An outer filter screen, the outer filter screen is installed on the top of the base;

[0010] A top seat, the top seat is arranged on the top of the outer filter screen, and the top seat is fixedly connected to the outer filter screen by bolts;

[0011] Filter element; the filter element is installed on the top of the base;

[0012] Inner filter; the inner filter is mounted on the top of the base and in contact with the top seat;

[0013] The top of the filter element is fixedly connected with a connecting plate, the top of the top seat is evenly provided with slots, the top seat is fixedly connected with the connecting plate by bolts, a bottom plate is arranged below the base, and a knocking mechanism is sleeved on the outer side of the bottom plate.

[0014] By removing the bolts, the top seat can be disassembled, so that the top seat can drive the second placement plate to discharge impurities through the telescopic rod.

[0015] Preferably, the knocking mechanism includes a first arc-shaped frame, which is sleeved on the outer wall of the base plate, and two symmetrically arranged rotating rods are rotatably connected in the first arc-shaped frame, and a plurality of fan blades are evenly installed on the rod walls of the two rotating rods, and two fixed blocks are installed on the top of the two rotating rods, and each group of the fixed blocks is slidably connected with a knocking head, and a second spring is installed between each group of the knocking head and the adjacent fixed blocks, and a second arc-shaped frame is installed on the top of the first arc-shaped frame, and the second arc-shaped frame is slidably connected to the base.

[0016] When the fan blades rotate, the rotating rod can drive the knocking head to rotate through the fixed block. When the knocking head contacts the base, the knocking head can squeeze the second spring. When the knocking head is away from the base, under the action of the second spring, the second spring extends and drives the knocking head back to the initial state.

[0024] When the base vibrates, the granular impurities on the outside of the filter element will be vibrated onto the second placement plate. When the granular impurities on the second placement plate reach a certain level, the first placement plate will be pressed downward and the third spring will be squeezed to facilitate the subsequent opening of the trigger mechanism.

[0025] Preferably, the trigger mechanism includes two contact blocks, the two contact blocks are respectively installed on the bottom of the first placement plate and the top of the base, an alarm is installed on the top of the top seat, and the two contact blocks are electrically connected to the alarm.

Magnets are installed on the opposite sides of the second placement plate and the first placement plate, and the two magnets are magnetically connected. A telescopic rod is installed on the top of the second placement plate, and the top of the telescopic rod is fixedly connected to the top seat.

[0028] By removing the bolts and then rotating the threaded tube to separate the air inlet pipe and the air outlet pipe, the top seat is removed and pulled upward, the telescopic rod can drive the second placement plate to move upward and separate the two magnets, so that the second placement plate can move upward to scrape the residual impurities on the outer wall of the filter element and discharge the impurities that fall on the top of the second placement plate to the outside.

[0029] Preferably, a plurality of support plates are evenly installed between the inner filter screen and the filter element.

[0030] By setting the support plate, the filter element can be supported, which can prevent the filter element from being twisted and uneven under the action of the compressor wind force, and the filtering area of ​​the filter element can be effectively utilized.

[0031] Preferably, the pipe walls of the oil outlet pipe and the connecting pipe located between the base and the bottom plate are both configured as telescopic pipes.
