Description

Technical Field

[0001] This utility model relates to the field of air conditioning refrigeration and heating technology, specifically an oil separator with a heated cleaning oil collection port. Background Technology

[0002] An oil separator separates the lubricating oil from the high-pressure refrigerant vapor discharged from a refrigeration compressor. It is typically installed between the compressor outlet and the condenser inlet. When the high-pressure refrigerant gas discharged from the compressor enters the separator, it passes through a filter and enters the condenser from the exhaust port. The lubricating oil mixed with the refrigerant gas is separated out and drips down, collecting in the oil collection port at the bottom of the container. This type of oil separator has a simple structure, is easy to manufacture, and is widely used.

[0003] However, existing oil separators still have the following technical problems in use:

[0004] The current oil separator typically has a threaded pipe at the bottom of the container as the drain port and a pipe connected to the compressor at the lower side of the container as the return port. The return port has an elbow inside that extends into the bottom of the container. This design increases the number of openings in the container during processing, makes cleaning the drain port inconvenient, results in higher oil viscosity during return, and leads to lower return efficiency.

[0005] Therefore, an oil separator with a heated cleaning oil collection port is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide an oil separator with a heated cleaning oil collection port to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an oil separator with a heated cleaning oil collection port, comprising an oil separator body, an exhaust pipe fixed to the upper side wall of the oil separator body, an air inlet pipe fixed to the left and right sides of the oil separator body, a filter screen fixed to the upper end inside the oil separator body, and an oil collection port fixed to the lower side wall of the oil separator body.

[0008] The oil collection port includes an oil tank body, a cleaning port, an oil return port, an oil drain port, and an oil heating port; the cleaning port is provided on the front side of the oil tank body, and a sealing cap is fixed inside the cleaning port by fastening bolts; an oil drain port is provided at the lower end of the inside of the oil tank body; oil return ports are fixed on the left and right sides of the oil tank body; and an oil heating port is provided on the rear side of the oil tank body.

[0009] Preferably, the oil collection port and the lower side of the oil separator body are welded together as a whole.

[0010] Preferably, the lower side wall of the oil separator body is fixedly provided with symmetrical support bases.

[0011] Preferably, the filter screen includes a first filter screen, two second filter screens and two third filter screens. The two second filter screens are respectively connected and fixed to the left and right sides of the first filter screen, and the two third filter screens are respectively connected and fixed to the front and rear sides of the first filter screen. The upper sides of the two second filter screens and the two third filter screens are all fixedly connected to the upper end of the inner wall of the oil separator body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Compared to previous oil separators, this oil separator combines an oil drain port and an oil return port in its oil collection port, and adds a cleaning port and an oil heating port, thereby reducing the number of openings in the container, facilitating the cleaning of oil sludge inside the oil collection port, and improving the oil return efficiency.
