Description

Technical Field

[0001] This utility model relates to the field of oil quantity measurement technology, specifically an oil quantity measurement cabinet. Background Technology

[0002] During generator operation, the oil metering cabinet is used to realize the oil transfer, metering and supply control between the oil depot and the generator. Its core function is to ensure stable oil transfer while preventing impurities in the oil from entering the generator oil supply pipeline, preventing wear and blockage of precision components, and affecting the reliability of generator operation.

[0003] Existing oil metering cabinets typically have filters installed on the flow lines to intercept impurities such as sludge and particulate matter in the oil. However, after long-term use, impurities tend to adhere to the surface of the filter screen. If not cleaned in time, this can lead to a reduction in the flow cross-sectional area, an increase in oil supply resistance, and even insufficient oil supply. Manual cleaning requires shutdown, which affects the continuity of power generation.

[0004] Therefore, this application proposes an oil metering cabinet. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an oil metering cabinet.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: An oil metering cabinet includes: a cabinet body; a flow guide pipe disposed within the cabinet body along its length, with its oil inlet end connected to an oil reservoir and its oil outlet end connected to a generator oil inlet pipe; a filter housing disposed in the middle of the flow guide pipe, containing an arc-shaped filter screen, a scraper, and a collection pipe; the arc-shaped filter screen being disposed along the oil flow direction, its projection covering the cross-section of the filter housing; the scraper having one end rotatably connected to the top side of the filter housing along its height direction, and its free end swinging along an axial plane with its swing path coinciding with the filtration surface of the arc-shaped filter screen; and a collection pipe disposed at the bottom of the filter housing, with its collection port disposed along the tangent direction of the lower end of the arc-shaped filter screen and communicating with the inside of the filter housing. In the initial state, the free end of the scraper rests on the edge of the receiving pipe's collection port and blocks the oil inlet end of the filter housing. When the oil enters, the free end of the scraper is squeezed and slides upward along the filter surface of the arc-shaped filter screen. The buoyancy of the oil on the scraper is greater than the sum of the scraper's own weight and the friction between it and the arc-shaped filter screen. After the oil injection is completed, the scraper slides down to scrape off the residue on the filter surface of the arc-shaped filter screen and returns to its original position. A sealed space is formed between the scraper and the oil inlet end of the filter housing to prevent backflow of oil.

[0007] Preferably, a return hopper is provided at the lower end of the guide pipe, the return hopper is located between the oil outlet end of the filter shell and the outlet end of the guide pipe, a return pipe is provided at the lower end of the return hopper, the other end of the return pipe is connected to the oil reservoir, and a one-way valve is provided inside the return pipe.

[0008] Preferably, the outlet end of the guide tube is equipped with a flow meter and a sensor.

[0009] Preferably, the free end of the scraper is provided with an elastic scraper strip, which slides in contact with the filter surface of the arc-shaped filter screen.

[0010] Preferably, the end of the collection tube away from the filter shell is detachably connected to a slag collection box, and the top of the collection box is provided with a sealing cover.

[0011] Preferably, a sealing gasket is provided at the connection between the guide tube and the filter shell, and the sealing gasket is made of oil-resistant rubber material.

[0012] Preferably, the collection port of the collection tube is provided with a guide slope, and the angle between the guide slope and the lower tangent of the arc-shaped filter screen is 15-30°.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, one end of the scraper is rotatably connected to the top side of the filter housing, and the free end swings along the same path as the filter surface of the arc-shaped filter screen. In the initial state, it blocks the oil inlet end of the filter housing. When oil is injected, the buoyancy of the oil pushes the scraper to slide up. After the oil is injected, the scraper slides down by its own gravity to scrape off the residue of the arc-shaped filter screen, thus achieving automatic cleaning of the arc-shaped filter screen.

[0014] 2. In this utility model, after the oil injection is completed, the scraper resets and forms a sealed space with the oil inlet end of the filter shell, which structurally blocks the oil backflow path and prevents the oil on the generator side from flowing back to the oil tank, causing oil pollution, metering errors or equipment failure, and ensuring the stability and safety of the oil circuit system.

Example

[0018] like Figures 1-2 As shown, an oil metering cabinet includes: a cabinet body 7; and a guide pipe 1, which is installed in the cabinet body 7 along its length, with its oil inlet end connected to an oil tank and its oil outlet end connected to a generator oil inlet pipe. The guide pipe 1 is installed in the cabinet body 7 along its length to achieve precise connection between the oil tank and the generator oil inlet pipe, thereby establishing a stable and efficient oil delivery channel, ensuring the continuity of oil delivery, and meeting the generator's continuous oil supply needs. The filter housing 3 is located in the middle of the guide pipe 1, and is equipped with an arc-shaped filter screen 2, a scraper 4 and a collection pipe 5 inside. The arc-shaped filter screen 2 is arranged along the direction of oil flow and its projection covers the cross-section of the filter housing 3. The arc-shaped filter screen 2 inside the filter housing 3 is arranged along the direction of oil flow and its projection covers the cross-section of the filter housing 3, which can filter the oil comprehensively and without dead angles, effectively intercept impurities and slag in the oil, prevent impurities from entering the generator and causing equipment wear and failure, and extend the service life of the generator. The scraper 4 has one end rotatably connected to the top inner side of the filter housing 3 along the height direction, and the free end swings along the axial plane with the swing path coinciding with the filter surface of the arc-shaped filter screen 2. The scraper 4 initially blocks the oil inlet of the filter housing 3. When oil is injected, the buoyancy of the oil pushes the scraper 4 to slide upward. After the oil is injected, the scraper 4 slides down by its own gravity to scrape off the residue of the arc-shaped filter screen 2, realizing automatic cleaning of the arc-shaped filter screen 2 without manual disassembly and cleaning, reducing maintenance costs and workload, and avoiding the impact of oil conveying efficiency on the blockage of the arc-shaped filter screen 2. The collection pipe 5 is located at the bottom of the filter shell 3, with the collection port set along the tangent direction of the lower end of the arc-shaped filter screen 2 and communicating with the inside of the filter shell 3. The collection pipe 5 is located at the bottom of the filter shell 3 and the collection port is set along the tangent direction of the lower end of the arc-shaped filter screen 2. It can accurately collect the slag scraped off by the scraper 4, prevent the slag from accumulating in the filter shell 3 and causing secondary pollution, and ensure the continuous and stable operation of the filtration system. In the initial state, the free end of scraper 4 rests on the edge of the collecting port of receiving pipe 5 and blocks the oil inlet of filter shell 3. When oil enters, the free end of scraper 4 is squeezed and slides upward along the filter surface of arc-shaped filter screen 2. The buoyancy of oil on scraper 4 is greater than the sum of the weight of scraper 4 and the friction between it and arc-shaped filter screen 2. After oil injection, scraper 4 slides down to scrape off the slag on the filter surface of arc-shaped filter screen 2 and resets. A sealed space is formed between scraper 4 and oil inlet of filter shell 3 to prevent oil backflow. After oil injection, scraper 4 resets and forms a sealed space with oil inlet of filter shell 3, which structurally blocks the oil backflow path and avoids oil backflow from generator side to oil tank, causing oil pollution, metering errors or equipment failure, and ensuring the stability and safety of oil circuit system.

[0019] In one embodiment, a return hopper 9 is provided at the lower end of the guide pipe 1. The return hopper 9 is located between the oil outlet end of the filter housing 3 and the outlet end of the guide pipe 1. The return hopper 9 is connected to the bottom of the guide pipe 1. A return pipe 6 is provided at the lower end of the return hopper 9. The other end of the return pipe 6 is connected to the oil reservoir. A one-way valve 10 is provided inside the return pipe 6.

[0020] Specifically, the return bucket 9 at the lower end of the guide pipe 1 is located between the oil outlet end of the filter housing 3 and the outlet end of the guide pipe 1. It can efficiently collect residual oil in the guide pipe 1, avoiding waste caused by oil stagnation in the pipe or deterioration due to long-term storage affecting subsequent use. The return pipe 6 connects the return bucket 9 to the oil tank, realizing the recycling and reuse of residual oil, reducing oil loss and saving resource costs. The one-way valve 10 in the return pipe 6 strictly restricts the direction of oil flow, allowing only residual oil to flow back to the oil tank, preventing oil in the oil tank from flowing back into the guide pipe 1, avoiding disruption of the one-way oil conveying order, and ensuring metering accuracy and the stability of the oil system.

[0021] In one embodiment, a flow meter 8 and a sensor are provided at the outlet end of the flow guide 1.

[0022] Specifically, the flow meter 8 at the outlet of the guide pipe 1 can accurately measure the total amount of oil delivered to the generator in real time, providing accurate data support for oil quantity management and cost accounting. This allows users to monitor oil consumption and plan oil replenishment accordingly. The sensor can monitor the oil delivery status in real time, such as abnormal flow and pressure fluctuations, and promptly report the oil circuit operation. This helps users quickly detect abnormalities such as blockage or leakage in the guide pipe 1, reducing the risk of equipment failure and ensuring stable generator operation.

[0023] In one embodiment, the free end of the scraper 4 is provided with an elastic scraper strip, which slides against the filter surface of the arc-shaped filter screen 2.

[0024] Specifically, the elastic scraper at the free end of the scraper 4 slides and adheres to the filter surface of the arc-shaped filter screen 2, which can greatly improve the fit between the scraper 4 and the filter surface of the arc-shaped filter screen 2. This allows for a more thorough removal of stubborn residues adhering to the surface of the arc-shaped filter screen 2, preventing residue residues from clogging the pores of the arc-shaped filter screen 2 and ensuring the long-term stability of the filtration efficiency of the arc-shaped filter screen 2. The elastic scraper has a certain elastic deformation capacity, which can buffer the contact pressure between the scraper 4 and the arc-shaped filter screen 2, avoiding hard contact that could cause wear on the arc-shaped filter screen 2, extending the service life of the arc-shaped filter screen 2 and the scraper 4. At the same time, it reduces the friction when the scraper 4 swings, ensuring that the scraper 4 can move up and down flexibly.

[0025] In one embodiment, a slag collection box is detachably connected to the end of the collection pipe 5 away from the filter shell 3, and a sealing cover is provided on the top of the collection box.

[0026] Specifically, the end of the collection pipe 5 furthest from the filter housing 3 is detachably connected to a waste collection box, enabling centralized collection of waste and preventing waste from accumulating and clogging the pipe, thus ensuring unobstructed waste collection. The detachable design of the collection box allows users to easily remove and clean the waste periodically, making operation convenient and reducing maintenance difficulty. The sealing cap on the top of the collection box effectively seals the box, preventing the spread of waste odors and preventing external dust and moisture from entering the box and contaminating or deteriorating the waste. It also prevents accidental leakage of waste from the collection box, which could cause environmental pollution.

[0027] In one embodiment, a sealing gasket is provided at the connection between the guide pipe 1 and the filter housing 3, and the sealing gasket is made of oil-resistant rubber material.

[0028] Specifically, the sealing gasket at the connection between the guide pipe 1 and the filter housing 3 fills the gap between the two, effectively preventing oil leakage from the interface and avoiding oil waste and safety hazards such as fire caused by flammable oil. The sealing gasket is made of oil-resistant rubber material, which has excellent oil resistance and anti-aging properties. It can withstand long-term immersion in oil without swelling or cracking, ensuring the long-term stable sealing performance of the connection between the guide pipe 1 and the filter housing 3, extending the replacement cycle of the sealing components and reducing maintenance costs.

[0029] In one embodiment, the collection port of the collection tube 5 is provided with a guide slope, and the angle between the guide slope and the lower tangent of the arc-shaped filter screen 2 is 15-30°.

[0030] Specifically, the guide slope at the collection port of the collection pipe 5 has an angle of 15-30° with the tangent at the bottom of the arc-shaped filter screen 2. This angle design can guide the slag scraped by the scraper 4 to slide quickly and smoothly into the collection pipe 5, avoiding the accumulation of slag at the bottom of the arc-shaped filter screen 2 or the edge of the collection port of the collection pipe 5, thus improving the slag collection efficiency. The reasonable angle design ensures the momentum of the sludge sliding down, while avoiding excessive angle causing sludge to splash or excessive angle causing sludge to clog the collection pipe 5. This ensures efficient collection and transportation of sludge by the collection pipe 5, further guaranteeing the stable operation of the filtration system.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
