Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil and gas separators, in particular to an external oil and gas separator device. Background Art
[0002] The oil-gas separator on the truck is used to separate the engine oil from the crankcase exhaust gas, reduce the oil discharged from the crankcase breathing port, and prevent the phenomenon of "false oil burning". The truck generally needs to replace the filter element every 20,000-30,000 kilometers.
[0003] Normally, the oil-gas separator shell and the separator cover of a truck are connected by four bolts. The separator cover needs to be removed when replacing the oil-gas separator filter element. The two bolts on the outside of the oil-gas separator are close to the vehicle side obstructions and there are fewer parts, so they are easier to disassemble. The two bolts on the inside are relatively troublesome to remove because the oil-gas separator is installed under the cab, close to the beam on the inside, and there are pipelines on the top. There are many obstructions, and operation is not very convenient. Utility Model Content
[0004] The purpose of the utility model is to provide an external oil-gas separator device to solve the problems raised in the above background technology.
[0005] In view of the above problems, the technical solution proposed by the present invention is:
[0006] An external oil-gas separator device includes a separator and a connector. The separator includes a first end cap, a second end cap, a first half shell, and a second half shell. The top and bottom ends of the first half shell are both equipped with connecting rings, which are installed inside the first and second end caps. A filter core is connected to the interior of the second half shell. The second half shell fits on both sides of the first half shell. The connector slides on the outside of the first and second end caps, and the connector fixes the first and second half shells together. The beneficial effect of adopting the above further scheme is that by dividing the traditional separator into a first half shell and a second half shell, and fixing the separated separators together using the connector, and connecting the filter core to the removable second half shell, when replacing the filter core, only the first half shell and the second half shell need to be separated by sliding the connector, and then the filter core in the second half shell can be removed, thereby replacing the traditional method of removing screws and then replacing the filter core, thereby achieving the purpose of making it easier for users to replace the filter core. Furthermore, the connecting member includes a pair of fixing rings, which slide on the outside of the first end cover and the second end cover respectively. The inside of the pair of fixing rings is provided with a first thread, and the outside of the first end cover and the second end cover is provided with a second thread, and the first thread and the second thread are engaged and connected.
[0007] Furthermore, a sliding groove is provided on the inner wall of the fixing ring, and a slip ring is installed on the outer side of the first end cover and the second end cover, and the slip ring slides in the sliding groove.
[0008] Furthermore, a sealing gasket is installed on the inner wall of the fixing ring.
[0009] The beneficial effect of adopting the above-mentioned further scheme is that, by utilizing the first thread and the second thread, the fixing ring can move up or down when rotating, and the position of the fixing ring is fixed at the same time. By utilizing the slip ring and the slide groove, when the fixing ring rotates to the top or the bottom, the slip ring will abut against one side of the slide groove. At this time, the fixing ring is tightened, that is, the fixing ring covers the outside of the first half shell and the second half shell, or does not cover the outside of the first half shell and the second half shell. When covering the outside of the first half shell and the second half shell, the first half shell and the second half shell will be tightly pressed together, and at the same time, a sealing gasket is used to cover the gap between the second half shell and the first end cover and the second end cover to ensure the sealing of the device. When not covering the outside of the first half shell and the second half shell, the first half shell and the second half shell can be separated.
[0010] Furthermore, a pair of sealing rings are installed on the outer side of the connecting ring, and sealing strips are installed on both sides of the inner wall of the second half shell, and the sealing strips are in contact with the inner wall of the first half shell.
[0011] The beneficial effect of adopting the above further solution is that a pair of sealing rings is used to improve the sealing between the connecting ring and the first end cover and the second end cover, and a sealing strip is used to improve the sealing between the first half shell and the second half shell.
[0012] Furthermore, a pair of clamps are installed on the inner wall of the second half shell, and the filter core is clamped in the pair of clamps. The beneficial effect of adopting the above further solution is that the filter core is fixed in the second half shell by the clamps, so that the user can quickly replace the filter core.
[0013] Furthermore, the outer side of the second end cover is connected to an air outlet pipe, the outer side of the first half shell is connected to a feed pipe, and the outer side of the second half shell is connected to an oil outlet pipe.
[0014] The beneficial effect of adopting the above further scheme is that the oil and gas to be separated enter the device through the feed pipe, and under the action of centrifugal force and filter element, the oil and gas are divided into gas and liquid, wherein the liquid flows out through the oil outlet pipe and the gas flows out through the gas outlet pipe, thereby achieving the purpose of oil and gas separation.
[0015] Compared with the prior art, the beneficial effect of the present invention is that the external oil-gas separator device divides the traditional separator into a first half shell and a second half shell, and uses a connecting piece to fix the separated separators together, while connecting the filter element and the removable second half shell. In this way, when replacing the filter element, it is only necessary to slide the connecting piece to separate the first half shell and the second half shell, and then take out the filter element in the second half shell, thereby replacing the traditional method of removing the screws and then replacing the filter element, thereby achieving the purpose of making it easier for users to replace the filter element.
