Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a device for separating oil mist from a speed reducer and eliminating oil leakage from an oil seal. Background Technology

[0002] The dryer's speed reducer has been in use for many years and is experiencing oil leakage from the oil seal. The current common solution is to perform special maintenance on the speed reducer, adding oil according to the oil level to maintain normal operation. However, when the leakage increases, it is necessary to shut down the machine and replace the speed reducer oil seal. A key issue arises: while the high-speed shaft oil seal can be replaced internally, replacing the low-speed shaft oil seal requires disassembling the speed reducer and outsourcing the replacement. This process is not only complex, but the downtime for speed reducer maintenance directly impacts the production line, significantly affecting production stability. Utility Model Content

[0003] In order to overcome the problems caused by oil leakage from the oil seal of the dryer's reducer after long-term use, such as oil pollution, increased oil consumption and maintenance costs, difficult repair, and impact on the normal operation of the production line, the present invention provides a device for separating oil mist from the reducer and eliminating oil leakage from the oil seal. The device uses compressed air to accelerate the spraying out through a nozzle, thereby driving the oil mist out of the air chamber.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a device for separating oil mist from a speed reducer and eliminating oil seal leakage, including a suction device, an air supply device and a discharge device. The speed reducer is connected to the air chamber through the suction device. The air supply device is inserted from one side of the air chamber and is tightly connected to the air chamber interface by welding. The discharge device is set on the other side of the air chamber.

[0005] Furthermore, the inhalation device is an inhalation tube, one end of which is connected to a speed reducer, and the other end of which is connected to an air chamber.

[0006] Furthermore, the connection between the inhalation tube and the reducer is a breathing cap, which serves as the interface between the inhalation device and the reducer.

[0007] Furthermore, the air supply device includes an air inlet pipe and a nozzle. The air inlet pipe is inserted from one side of the air chamber and is tightly connected to the air chamber interface by welding. The nozzle is provided at the end of the air inlet pipe inside the air chamber, and the end of the air inlet pipe outside the air chamber is connected to the air source device.

[0008] Furthermore, the nozzle is welded together from two 1 / 2-inch x 3 / 4-inch heads.

[0009] Furthermore, the air source device is a compressor, which is connected to the end of the air inlet pipe via an air supply pipe.

[0010] Furthermore, the discharge device is a throat tube, one end of which is connected to the air chamber.

[0011] Furthermore, the other end of the throat is connected to the diffuser tube.

[0012] Furthermore, the diffuser tube is a trumpet-shaped structure with a gradually increasing diameter.

[0013] Furthermore, the air chamber is a combination of a cylindrical and a frustum-shaped structure.

[0014] The beneficial effects of this utility model are as follows: It employs a device for separating oil mist from a speed reducer and eliminating oil seal leakage. An oil mist extraction device is installed at the breather cap of the speed reducer, utilizing air pressure and rapidly flowing air to remove oil mist from inside the speed reducer. This technical solution effectively eliminates the problem of speed reducer oil leakage, thereby preventing oil pollution of equipment and the environment. The reduction in oil leakage reduces the need for frequent refueling, thus saving refueling costs. It also avoids temporary shutdowns and frequent oil seal replacements caused by oil leakage, reducing production losses and maintenance costs due to downtime. It saves on labor costs required for oil seal maintenance and replacement. By reducing downtime caused by oil leakage, it improves the stability and overall efficiency of the production line. Finally, it reduces oil pollution to the environment, meeting environmental protection requirements. Attached Figure Description

[0028] A device for separating oil mist from a speed reducer and eliminating oil leakage from the oil seal achieves the technical effect of eliminating oil leakage from the speed reducer through the combined action of an intake device, an air supply device, and an exhaust device. The intake device consists of a speed reducer and an intake pipe. The air supply device consists of an intake pipe 2 and a nozzle 3. The exhaust device consists of an air chamber 1, a throat 4, and a diffuser 5. One end of the intake pipe 6 is tightly connected to the speed reducer 7 and collects the oil mist escaping from inside the speed reducer 7. The other end is connected to the air chamber 1, forming a channel for oil mist transmission. One side of the air chamber 1 is connected to the intake pipe 2, which is connected to the nozzle 3. Its nozzle is directed towards the throat 4, spraying high-pressure gas in the form of a high-speed jet, directly impacting the inside of the throat 4. Instantly, a significant low-pressure area is formed inside the throat 4, which can draw in the oil mist generated inside the speed reducer and the lubricating oil that may leak through the oil seal. Under the action of high-speed airflow and atmospheric pressure, the oil mist is drawn into the throat 4 and finally discharged through the diffuser.

The intake pipe 2 introduces compressed air from the air supply pipe into the device; one end of the throat pipe 4 is connected to the air chamber 1, and the other end is connected to the diffuser 5; the air chamber 1 is a combination structure of cylinder and frustum shape.
