Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm pumps, in particular to a large-scale diaphragm pump oil return sedimentation tank. Background Art

[0002] Diaphragm pumps are used to transport high-concentration tailings in the mineral processing industry. Their principle is that a reciprocating diaphragm pump is powered by an electric motor, which, through a coupling and reducer, drives the crankshaft, connecting rod, and crosshead, converting rotary motion into linear motion. This drives the piston in reciprocating motion, which then transmits hydraulic pressure through a hydraulic pipe to the diaphragm chamber of the cylinder. As the piston moves toward the rear, it uses the oil medium to draw the diaphragm in the diaphragm chamber backward. Backflow pressure from the slurry inlet (feeding) opens the feed valve, drawing in slurry to fill the diaphragm chamber. As the piston moves toward the front, the oil medium pushes the diaphragm in the diaphragm chamber forward, closing the feed valve with the propulsion pressure and opening the discharge valve to transfer the slurry to the discharge pipe.

[0003] From the working principle of the reciprocating diaphragm pump, it can be seen that its slurry transportation is to push and pull the diaphragm to reciprocate through the lubricating oil medium in the diaphragm chamber. During its operation, the diaphragm pump piston is lubricated by the oil injection pump. When the amount of lubricating oil in the diaphragm chamber does not meet the requirements, the diaphragm chamber is replenished or drained by the oil replenishment and discharge pump. The injection and replenishment lubricating grease then enters the oil tank through the return oil pipeline. When the replenishment and discharge oil circuit is contaminated or the injection oil circuit is contaminated, it will cause pollution to the entire oil tank and affect the quality of the lubricating oil in other oil circuits. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a large diaphragm pump return oil sedimentation tank.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0006] A large diaphragm pump return oil sedimentation tank, comprising:

[0007] The sedimentation zone has a top inlet corresponding to the outlet of the oil return line;

[0008] The inlet end of the oil replenishment area is connected to the overflow port of the sedimentation area;

[0009] The injection zone, the inlet end and the overflow port of the oil replenishment zone are connected to each other;

[0010] Among them, overflow filters are provided on the overflow ports of the sedimentation area and the oil replenishment area; the oil replenishment area is connected to the oil circuit of the replenishment and discharge oil pump, and the injection area is connected to the oil circuit of the injection pump.

[0011] An oil drain pipe is provided on the side wall of the bottom of the sedimentation area, and an oil drain port is provided at the bottom of the injection area and the oil replenishment area.

[0012] Scales are provided on the side walls of the sedimentation area and the oil replenishment area.

[0013] The beneficial effects of the present utility model are as follows: the present utility model upgrades and reconstructs the integral oil tank of the diaphragm pump. The crude oil tank is an integral box body for oil replenishment, lubrication and oil injection. If oil contamination occurs, the entire lubricating oil will be affected. The oil tank is upgraded and reconstructed into a three-step overflow combination oil tank, namely the sedimentation area, the oil replenishment area, and the injection area, to ensure the cleanliness of the oil in the oil replenishment tank and the injection tank to the greatest extent. When the present utility model is in operation, when the return oil of the diaphragm pump enters the sedimentation area and the oil level is higher than the overflow port of the sedimentation area, the overflow enters the oil replenishment area. When the oil level in the oil replenishment area is higher than the overflow port, the overflow enters the injection area. During the overflow formation process at each stage, some impurities will settle at the bottom of each area, thereby ensuring the excellent oil quality in the oil replenishment area and the injection area, and achieving the best lubrication effect. The utility model solves the problem that when the oil in a single position of the diaphragm pump is contaminated, the entire oil tank is contaminated, which affects the service life of equipment parts; it solves the problem that after the diaphragm pump oil tank is contaminated, it is time-consuming and labor-intensive to replace the lubricating oil, thereby wasting lubricating oil, thereby extending the service life of the diaphragm pump parts and improving the quality of the lubricating oil circulated in the pump.

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0019] like Figures 1 to 3As shown, a large diaphragm pump return oil settling tank includes: a settling area 5, whose top inlet corresponds to the outlet of the return oil pipeline 4; an oil replenishment area 6, whose inlet communicates with the overflow port of the settling area 5; and an injection area 7, whose inlet communicates with the overflow port of the oil replenishment area 6. Overflow filters 2 are installed on the overflow ports of both the settling area 5 and the oil replenishment area 6; the oil replenishment area 6 is connected to the oil circuit of the oil replenishment and discharge pump, and the injection area 7 is connected to the oil circuit of the injection pump. An oil drain pipe 1 is installed on the bottom sidewall of the settling area 5, and an oil drain port 3 is installed at the bottom of both the injection area 7 and the oil replenishment area 6. Scales 8 are installed on the sidewalls of both the settling area 5 and the oil replenishment area 6.

[0020] When the utility model is in use, the lubricating oil of the diaphragm pump is lubricated from the cylinder body and then returned to the sedimentation area 5. When the oil level is higher than the overflow port of the sedimentation area 5, it overflows to the oil replenishing area 6. When the oil level is higher than the overflow port of the oil replenishing area 6, it overflows to the injection area 7. In the overflow process, the overflow filter 2 provided on the overflow port is used to filter the lubricating oil in each oil tank. In the process of overflow formation at each stage, some impurities will be settled at the bottom of each area, thereby ensuring that the oil quality in the oil replenishing area 6 and the injection area 7 is excellent, and achieving the best lubrication effect.
