Description

Technical Field

[0001] This utility model relates to the field of oil return detection technology for equipment lubrication systems, and in particular to an oil return detection device for lubrication systems based on a mercury switch. Background Technology

[0002] The copper system in the ore processing company's crushing area is outdated due to its early construction. The lubrication system for the crushers lacks a return oil detection device, operating in isolation with only pump operation signals available on-site. With limited on-site personnel, routine inspections fail to promptly identify lubrication issues. During crushing operation, problems such as pump interruptions, leaks, and blockages frequently lead to insufficient return oil or incomplete lubrication, resulting in serious production and equipment accidents such as bearing burnout and horizontal shaft seizure. Utility Model Content

[0003] The purpose of this invention is to provide a lubrication system return oil detection device based on a mercury switch, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A lubrication system return oil detection device based on a mercury switch includes a return oil connection port fixed at the return oil outlet position inside the oil tank. The return oil connection port is a hollow right-angled trapezoidal structure with an opening at the top. A return oil baffle is hinged to the top of the return oil connection port, and a mercury switch is installed on the outer wall of the return oil baffle.

[0006] The oil return connection and oil return baffle are both made of copper or iron sheet.

[0007] One side of the oil return baffle is provided with a limiting plate facing the oil return connection port.

[0008] The length of the limiting plate is less than the length of the upper bottom of the oil return connection port.

[0009] The return oil baffle contacts the end of the return oil pipe when the system is oil-free.

[0010] The end of the return oil pipe is provided with a mounting plate for installing the return oil connection port.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] This utility model can be directly installed on the oil return pipe outlet of the lubrication system of old equipment. During the operation of the equipment, it can realize real-time monitoring of the lubrication return status of the crushing equipment and issue corresponding alarm information, realize remote monitoring of the lubrication return status of the equipment, achieve unmanned automatic control or remote central control, save personnel costs, improve the stable operation efficiency of the equipment, and reduce maintenance costs.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] like Figure 1-4As shown, this utility model provides a lubrication system return oil detection device based on a mercury switch, including an oil tank 3, an oil return pipe 5 on the oil tank 3, an installation plate on the oil return pipe 5 located inside the oil tank 3, an oil return connection port 4 fixedly installed on the installation plate by screws, the oil return connection port 4 is a hollow right-angled trapezoidal structure with an open top, an oil return baffle 1 is hinged to the top of the oil return connection port 4, a limiting plate 6 is provided on one side of the oil return baffle 1 facing the oil return connection port 4, the length of the limiting plate 6 is less than the length of the top bottom of the oil return connection port 4, used to prevent the oil return baffle 1 from detaching from the oil return connection port 4, ensuring the normal operation of the oil return baffle 1; a mercury switch 2 is fixedly installed on the outer wall of the oil return baffle 1 by a clamp strip, the clamp strip is made of copper sheet, used to wrap and fix the mercury switch 2 and then fix it on the oil return baffle 1 by small bolts. The oil return baffle 1 is in contact with the end of the oil return pipe 5 when the system is without oil, and can be lifted up when the system is with oil. The oil return connection port 4 and the oil return baffle 1 are both made of copper or iron sheet.

[0021] The principle of this invention is as follows: Based on the size of the oil outlet of the oil return pipe 5, thin copper or iron sheets are cut to make the oil return connector 4, the oil return baffle 1, and the copper strip for fixing the mercury switch 2. The oil return connector 4 is directly fixed to the mounting plate inside the oil tank through fixing holes. The oil return baffle 1 and the oil return connector 4 are hinged together by passing a thin iron wire through the opening. The iron strip is clipped onto the mercury switch 2 and fixed to the oil return baffle 1 with small screws and nuts. On-site, the position of the mercury switch 2 is adjusted according to the presence and absence of oil at the oil return port to ensure that when the oil level is too low or there is no oil, the mercury in the mercury switch 2 is located at the front end of the mercury switch 2, and when the oil level is normal, the mercury in the mercury switch 2 is located between the two electrodes.
