Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration oil separator technology, specifically to an automatic drainage device for an ultrafiltration oil separator. Background Technology

[0002] Ultrafiltration oil separators are high-efficiency oil purification devices widely used in shipbuilding, power, and industrial fields to remove water and impurities from lubricating oil and fuel oil, ensuring stable equipment operation. Through physical separation technology, they efficiently remove free water, emulsified water, and solid particles from oil, significantly reducing the water content (down to below 100 ppm), preventing equipment corrosion, wear, or performance degradation caused by moisture, and extending the service life of mechanical equipment (such as engines, hydraulic systems, and turbines).

[0003] Traditional ultrafiltration oil separators rely on manual drainage at regular intervals, requiring operators to periodically check the water level in the collection chamber and open the valve to drain accumulated water. This method has significant drawbacks: firstly, manual inspections are susceptible to negligence or reliance on experience; if the drainage interval is too long, water may re-mix into the oil, leading to excessive water content. Secondly, frequent manual operation increases labor intensity, and in scenarios requiring continuous operation, such as ships and power plants, it is difficult to guarantee timely drainage, potentially causing problems such as poor equipment lubrication or decreased hydraulic system efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic drainage device for an ultrafiltration oil separator, which solves the problem that the traditional manual drainage of an ultrafiltration oil separator relies on manual timed operation, which is prone to water not being discharged in time due to negligence or inspection intervals, and thus being mixed back into the oil.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic drainage device for an ultrafiltration oil separator, comprising a first filter element, an inlet pipe fixedly connected to the upper end of the first filter element, a connecting pipe fixedly connected to the lower end of the first filter element, a second filter element fixedly connected to the end of the connecting pipe away from the first filter element, an outlet pipe fixedly connected to the lower end of the second filter element, a valve provided on the outlet pipe, a sleeve inserted inside the outlet pipe, a sliding rod slidably connected inside the sleeve, a sealing gasket fixedly connected to the end of the sliding rod near the outlet pipe, the sealing gasket slidably connected to the outlet pipe, a spring provided on the outside of the sliding rod, an outlet hole opened inside the sleeve, and a fixing mechanism provided on the outside of the outlet pipe.

[0006] Preferably, a limiting ring is fixedly connected inside the water outlet pipe. The limiting ring contacts the sealing gasket, and the design of the limiting ring can limit the sealing gasket.

[0007] Preferably, one end of the spring contacts the sleeve, and the other end of the spring contacts the slide rod. Through the design of the spring, the sealing gasket can be reset.

[0008] Preferably, the fixing mechanism includes a fixing block, a fixing block is fixedly connected to the outer side of the water outlet pipe, a connecting block is fixedly connected to the outer side of the sleeve, the fixing block is in contact with the connecting block, a slider is slidably connected inside the fixing block, a guide block is fixedly connected to the side of the slider near the connecting block, the guide block is slidably connected to the fixing block, a locking block is fixedly connected to the end of the guide block away from the slider, a locking groove is opened inside the connecting block, a threaded rod is rotatably connected inside the fixing block, a retaining ring is fixedly connected to the outer side of the threaded rod, and the retaining ring is in contact with the inner wall of the fixing block. Through the design of the fixing mechanism, the sleeve and the water outlet pipe can remain stable during installation.

[0009] Preferably, the locking block contacts the fixing block, and the other end of the locking block engages with the locking slot. Through the design of the locking block, the connecting block can be limited.

[0010] Preferably, the outer side of the threaded rod is provided with positive and negative threads, and the threaded rod is connected to the slider by threads. Through the design of the threaded rod, two sliders can be moved simultaneously.

[0011] Preferably, a knob is fixedly connected to the upper end of the threaded rod, and the knob contacts the fixed block. The design of the knob allows the threaded rod to be rotated easily.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by incorporating components such as a sliding rod, sealing gasket, and spring, allows drainage through the outlet pipe. When the water pressure is too high, the sealing gasket will compress the spring, preventing it from blocking the outlet hole and allowing water to flow through. This solves the problem of traditional manual drainage in ultrafiltration oil separators, which relies on timed manual operation and is prone to water not being discharged in time due to negligence or inspection intervals, resulting in water re-mixing into the oil.

[0014] 2. This utility model innovatively configures a slider, locking block, and threaded rod as a cooperating component. Rotating the threaded rod drives the slider to generate precise threaded displacement, causing the locking block to tightly engage with the connecting block, achieving rapid locking of the sleeve on the outlet pipe. This design ensures the sleeve remains stable and does not wobble during drainage, avoiding the problem of easy loosening in traditional fixing methods. The structure is simple, operation is convenient, and it significantly improves the connection reliability and stability of the drainage device. Attached Figure Description

[0020] Please see Figure 1-4 An automatic drainage device for an ultrafiltration oil separator includes a first filter element 1. An inlet pipe 11 is fixedly connected to the upper end of the first filter element 1. A connecting pipe 12 is fixedly connected to the lower end of the first filter element 1. A second filter element 13 is fixedly connected to the end of the connecting pipe 12 away from the first filter element 1. An outlet pipe 2 is fixedly connected to the lower end of the second filter element 13. A valve 21 is installed on the outlet pipe 2. A sleeve 3 is inserted into the inside of the outlet pipe 2. A sliding rod 31 is slidably connected inside the sleeve 3. A sealing gasket 32 ​​is fixedly connected to the end of the sliding rod 31 near the outlet pipe 2. The sealing gasket 32 ​​is slidably connected to the outlet pipe 2.

[0021] Please see Figure 2-4 The water outlet pipe 2 is internally fixedly connected to a limiting ring 33, which contacts the sealing gasket 32. The limiting ring 33 is designed to limit the sealing gasket 32. A spring 34 is provided on the outside of the slide rod 31. One end of the spring 34 contacts the sleeve 3, and the other end of the spring 34 contacts the slide rod 31. The spring 34 is designed to drive the sealing gasket 32 ​​to reset. A water outlet hole 35 is provided inside the sleeve 3, and a fixing mechanism 4 is provided on the outside of the water outlet pipe 2.

[0022] Please see Figure 2-4The fixing mechanism 4 includes a fixing block 41. The fixing block 41 is fixedly connected to the outside of the outlet pipe 2, and a connecting block 42 is fixedly connected to the outside of the sleeve 3. The fixing block 41 contacts the connecting block 42. A slider 43 is slidably connected inside the fixing block 41. A guide block 44 is fixedly connected to the side of the slider 43 closest to the connecting block 42. The guide block 44 is slidably connected to the fixing block 41. A locking block 45 is fixedly connected to the end of the guide block 44 away from the slider 43. A locking groove 46 is provided inside the connecting block 42. The locking block 45 contacts the fixing block 41, and the other end of the locking block 45 engages with the locking groove 46. Through the design of the locking block 45, the water outlet pipe 2 can be fixedly connected to the connecting block 42. The connecting block 42 serves as a limit, and the fixed block 41 is rotatably connected to a threaded rod 47. The outer side of the threaded rod 47 is provided with positive and negative threads. The threaded rod 47 is connected to the slider 43 by threads. Through the design of the threaded rod 47, two sliders 43 can be moved simultaneously. A retaining ring 48 is fixedly connected to the outer side of the threaded rod 47. The retaining ring 48 contacts the inner wall of the fixed block 41. A knob 49 is fixedly connected to the upper end of the threaded rod 47. The knob 49 contacts the fixed block 41. Through the design of the knob 49, the threaded rod 47 can be easily rotated. Through the design of the fixing mechanism 4, the sleeve 3 and the water outlet pipe 2 can be kept stable during installation.

[0023] The specific implementation process of this utility model is as follows: In use, by inserting the sleeve 3 into the water outlet pipe 2, the connecting block 42 slides on the locking block 45 on the fixing block 41, and the locking block 45 slides into the locking groove 46 on the connecting block 42. Then, the knob 49 is rotated, which drives the threaded rod 47 to rotate, causing the threaded rod 47 and the slider 43 to move in a threaded motion, thereby causing the slider 43 to move on the threaded rod 47, causing the slider 43 to drive the guide block 44 to move, causing the guide block 44 to drive the locking block 45 to move, and causing the locking block 45 to engage with the connecting block 42, thus fixing the sleeve 3 on the water outlet pipe 2.

[0024] When draining water from outlet pipe 2, water flows into sleeve 3, causing the sealing gasket 32 ​​to slide inside sleeve 3. The sealing gasket 32 ​​then causes the sliding rod 31 to slide inside sleeve 3, which in turn compresses the spring 34. This prevents the sealing gasket 32 ​​from blocking the water outlet hole 35 on sleeve 3, allowing water to drain through the water outlet hole 35.
