Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, specifically to a centrifugal pump filling and exhaust discharge material recovery device that is pollution-free. Background Technology

[0002] Before starting or during operation, gas accumulates inside the centrifugal pump used for loading and unloading in storage and transportation workshops. Therefore, venting and priming the pump are necessary before starting. Traditional venting methods typically release the gas directly into the atmosphere, which not only releases the gas but also intermittently discharges large amounts of material, leading to environmental pollution and material waste.

[0003] Therefore, a recycling device is designed to ensure that the material discharged from the priming pump of a centrifugal pump is free from pollution. Utility Model Content

[0004] The present invention aims to solve the above-mentioned problems by providing a centrifugal pump filling pump exhaust discharge material recovery device without pollution.

[0005] This utility model is achieved through the following technical solution: a centrifugal pump filling and exhaust discharge material pollution-free recovery device, characterized in that it includes a centrifugal pump and a visual recovery device. The outlet of the centrifugal pump is connected to the visual recovery device through an exhaust pipe. A control valve is provided on the exhaust pipe near the centrifugal pump side, and an exhaust valve is provided on the exhaust pipe near the visual recovery device side. An air intake pipe is provided on one side of the top of the visual recovery device, and an air intake valve is provided on the air intake pipe. An oil and gas recovery pipe is provided on the other side, and a switch valve is provided on the oil and gas recovery pipe. The outlet of the visual recovery device is connected to the inlet of the centrifugal pump through a discharge pipe, and a check valve is provided on the discharge pipe.

[0006] Furthermore, the visual recycling device uses a material recycling container with a transparent viewing window.

[0007] The beneficial effects of this utility model are: This utility model realizes the visual recycling of centrifugal pump exhaust materials through a visual recycling device, avoiding environmental pollution and material waste. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the structure of this utility model.

[0009] In the attached diagram, 1 is a centrifugal pump, 2 is a control valve, 3 is an exhaust valve, 4 is a suction valve, 6 is a visible recovery device, 7 is a switch valve, and 8 is a check valve. Detailed Implementation

[0010] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further explained below in conjunction with the embodiments.

[0011] like Figure 1As shown, a pollution-free material recovery device for the priming and exhaust discharge of a centrifugal pump 1 includes a centrifugal pump 1 and a visual recovery device 6. The outlet of the centrifugal pump 1 is connected to the visual recovery device 6 through an exhaust pipe. A control valve 2 is provided on the exhaust pipe near the centrifugal pump 1, and an exhaust valve 3 is provided on the exhaust pipe near the visual recovery device 6. An air intake pipe is provided on one side of the top of the visual recovery device 6, and an air intake valve 4 is provided on the air intake pipe. An oil and gas recovery pipe is provided on the other side, and a switch valve 7 is provided on the oil and gas recovery pipe. The outlet of the visual recovery device 6 is connected to the inlet of the centrifugal pump 1 through a discharge pipe, and a check valve 8 is provided on the discharge pipe.

[0012] The visual recycling device 6 uses a material recycling container with a transparent viewing window, typically a recycling tank with a viewing window.

[0013] The function of check valve 8 is to prevent material from flowing through the discharge pipe to the visible recycling device 6.

[0014] The function of suction valve 4 is to prevent the container from collapsing due to negative pressure.

[0015] Before centrifugal pump 1 starts operating, it exhausts gas, which carries the material, through the exhaust pipe to the visual recovery device 6. The recovery status of the material is observed in real time through a transparent observation window. The material recovered into the visual recovery device 6 recovers oil and gas through the oil and gas recovery pipe. Then, after the flow rate and pressure of centrifugal pump 1 stabilize, the material is pumped to the inlet of centrifugal pump 1 through the discharge pipe.

[0016] Except for the technical features described in the specification, all other technical features are known to those skilled in the art.
