Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil filtration technology, specifically a filter element for oil depot transportation. Background Technology
[0002] In the petrochemical industry, the efficient and stable operation of oil depot transportation systems is crucial, and filter elements, as key components in these systems, directly affect the filtration quality and transportation efficiency of the oil.
[0003] Traditional oil depot filter elements primarily filter impurities from oil through physical interception. However, these filter elements generally lack heating functionality. In cold winters, especially in frigid regions, the viscosity of the oil increases significantly, reducing its fluidity and increasing resistance as the oil passes through the filter element, drastically reducing filtration efficiency. In severe cases, high-viscosity oil can even clog the filter element, not only affecting normal oil depot operations but also potentially causing safety hazards due to excessive pressure.
[0004] In existing technologies, although some oil depots use external heating equipment to preheat the oil, this method requires additional equipment investment, which increases the complexity and cost of the system. Moreover, the heating effect is uneven, and it is difficult to accurately control the oil temperature, which cannot fundamentally solve the problem of low efficiency of filter elements in low-temperature environments. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a filter element for oil depot transportation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A filter element for oil depot conveying includes: an oil inlet valve, a cylinder body 1 at the bottom of the oil inlet valve, a plurality of circular through holes at the lower part of the cylinder body 1, a filter element seat at the bottom of the cylinder body 1, the cylinder body 1 being threadedly connected to the filter element seat, a heating base at the bottom of the filter element seat, a cylinder body 2 at the top of the filter element seat, a plurality of elliptical through holes on the outer wall of the cylinder body 2, a plurality of heating tubes at the top of the filter element seat, a support rod at the center of the filter element seat, a circular support plate fixedly mounted on the support rod, and a filter element mounted on the circular support plate.
[0008] The oil inlet valve is used to control the inlet and outlet of the oil; the circular through hole in cylinder one is used for filtering the oil; cylinder two is used to enclose the oil, allowing the oil to seep out from the elliptical through hole; the heating base is connected to the heating pipe to maintain the oil at a level of 60°C.
[0009] Preferably, the circular support plate of the filter element holder is composed of multiple rings, with columns fixed between the rings. The rings are used to allow the oil to enter the heating pipe at the bottom of the cylinder after passing through the filter element.
[0010] The bottom of the filter cartridge holder is hollow, and multiple temperature sensors are installed on the top of the filter cartridge holder; the bottom of the heating tube has a power insertion groove.
[0011] Preferably, the heating base is provided with an embedding platform, which is used to snap-fit with the hollow part at the bottom of the filter element seat. The top of the embedding platform is provided with multiple plugs, which are embedded in the insertion groove at the bottom of the heating tube.
[0012] The heating base has a display screen on the front side, which displays the oil temperature data transmitted by the temperature sensor; the heating base has a power socket on the rear side.
[0013] Preferably, a fixing seat is provided on the right side of the oil inlet valve, which is used to fix the device in the corresponding position. Compared with the prior art, this utility model provides a filter element for oil depot conveying, which has the following beneficial effects:
[0014] The embedding platform on the heating base can be snapped together with the hollow part at the bottom of the filter element holder. The multiple plugs on the top of the embedding platform are embedded in the electrical groove at the bottom of the heating tube, realizing a reliable electrical connection between the heating base and the heating tube, and ensuring the stable operation of the heating function.
[0015] Multiple heating tubes on the top of the filter element holder work in conjunction with the heating base to uniformly heat the oil, maintaining it at a suitable temperature of 60°C. This effectively reduces oil viscosity and improves its fluidity, significantly enhancing the filter element's filtration efficiency in low-temperature environments. The display screen on the front of the heating base shows the oil temperature data transmitted from the temperature sensor in real time, allowing operators to intuitively understand the oil temperature and adjust the heating settings accordingly. This ensures the oil temperature remains at the optimal level of 60°C, effectively guaranteeing oil fluidity and improving filtration efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-6 As shown, an oil depot conveying filter element of this embodiment includes an oil inlet valve 2. A cylindrical body 1 is located at the bottom of the oil inlet valve 2. Multiple circular through holes 101 are evenly distributed on the lower part of the cylindrical body 1. The bottom end of the cylindrical body 1 is connected to a filter element seat 4 via threads, facilitating disassembly and installation of the filter element seat 4. A heating base 3 is located at the bottom of the filter element seat 4. A cylindrical body 5 is fixedly mounted on the top of the filter element seat 4. Multiple elliptical through holes 501 are provided on the outer wall of the cylindrical body 5 for oil seepage. Multiple sets of heating tubes 401 are installed on the top of the filter element seat 4. A support rod 403 is vertically arranged in the center of the filter element seat 4. A circular support plate 402 is fixed on the support rod 403, and a filter element 6 is placed on the circular support plate 402.
[0025] The oil inlet valve 2 is used to control the inlet and outlet of the oil. The circular through hole 101 in the first cylinder 1 is used for the filtered oil to flow out. The second cylinder 5 encloses the oil and allows it to seep out from the elliptical through hole 501. The heating base 3 is connected to the heating pipe 401 to maintain the oil temperature at 60°C, ensuring that the oil maintains good fluidity in a low-temperature environment.
[0026] In some examples, refer to Figures 4-5 As shown, the circular support plate 402 of the filter element seat 4 is composed of multiple concentric rings, which are fixed by columns to form a hollow structure. This structure design allows the oil to pass through the gaps between the rings after being filtered by the filter element 6 and smoothly enter the heating pipe 401 at the bottom of the cylinder 5, ensuring smooth flow of the oil during the heating process and avoiding blockage.
[0027] In some examples, the bottom of the filter element holder 4 is hollow and snaps into place with the embedding platform on the heating base 3. Multiple temperature sensors (not shown) are installed on the top of the filter element holder 4 for real-time monitoring of the oil temperature. The bottom of the heating tube 401 has a recessed insertion groove that engages with the plug 301 on the top of the embedding platform of the heating base 3, ensuring a stable electrical connection between the heating tube 401 and the heating base 3 and guaranteeing reliable operation of the heating function.
[0028] In some examples, a display screen is located on the front of the heating base 3. This display screen is electrically connected to a temperature sensor on the top of the filter element holder 4 to display the oil temperature data transmitted by the temperature sensor in real time. Operators can adjust the heating status in a timely manner based on the data displayed on the screen to ensure that the oil temperature is always maintained at the optimal level of 60°C. A power socket 303 is located on the rear of the heating base 3 for easy connection to an external power source to provide power support for the entire heating system.
[0029] In some examples, a mounting base 201 is fixedly installed on the right side of the oil inlet valve 2. The mounting base 201 is provided with mounting holes. The entire device can be fixed in the corresponding position of the oil depot conveying system by bolts and other fasteners, which improves the installation stability and applicability of the device and meets the usage requirements under different working conditions.
[0030] In some examples, a sealing gasket (not shown) is provided at the threaded connection between the cylinder 1 and the filter element seat 4. The sealing gasket is made of oil-resistant rubber material, which can effectively prevent oil leakage, improve the sealing performance of the device, and ensure the safety and reliability of the oil filtration process.
[0031] In some examples, the elliptical through holes 501 of the second cylinder 5 are distributed at an inclined downward angle of 30°. This design helps the oil to seep out more smoothly from the elliptical through holes 501 under the action of gravity, reducing the oil residue in the second cylinder 5 and improving the filtration efficiency and oil utilization rate.
[0032] In some examples, a protective baffle or cover is provided at the power socket 501 of the heating base 3 to prevent oil from entering the power socket 501.
[0033] The working principle of this utility model is as follows:
[0034] When using this type of filter element for oil depot transportation, first, according to the layout of the oil depot transportation system, the device is stably installed in the corresponding position through the fixing seat 201 on the right side of the oil inlet valve 2. The structural design of the fixing seat 201 ensures that the filter element will not be displaced due to vibration or other factors during transportation, providing a stable foundation for subsequent filtration work.
[0035] When the oil needs to be filtered and transported, the operator opens the inlet valve 2, and the oil flows into the cylinder 5 from the inlet valve 2. The outer wall of the cylinder 5 is provided with multiple elliptical through holes 501, but at this time the oil has not been filtered and needs to pass through the filter element 6 to remove impurities. The oil flows downward and comes into contact with the filter element 6 supported by the circular support plate 402 on the central support rod 403 of the filter element seat 4. Impurities are intercepted by the filter element 6, and the oil that meets the filtration requirements passes through the filter element 6.
[0036] Since the circular support plate 402 of the filter element holder 4 is composed of multiple rings, and the rings are fixed by columns to form a hollow structure, the filtered oil can pass smoothly through the gaps between the rings and enter the area where the heating pipe 401 is located at the bottom of the cylinder 5. At this time, the heating base 3 and the heating pipe 401 are electrically connected through the plug 301 and the plug groove at the bottom, and the heating pipe 401 starts to work, heating the surrounding oil.
[0037] Multiple temperature sensors mounted on the top of the filter element holder 4 monitor the oil temperature in real time and transmit the data to the display screen on the front of the heating base 3. Operators can visually view the oil temperature on the display screen. When the temperature drops below 60℃, the heating system automatically or manually adjusts its power to ensure the oil temperature is maintained at the optimal operating temperature. The heated oil has reduced viscosity and increased fluidity, subsequently flowing upwards into the cylinder 1.
[0038] Multiple circular through holes 101 at the bottom of the cylinder 1 serve as oil outlet channels. The oil outlet channels are connected to the oil tank. The heated and filtered oil flows out from here, completing the entire filtration and transportation process. The flowing oil slides into the oil tank for storage, which is convenient for subsequent use.
[0039] During this process, the cylinder 1 and the filter element seat 4 are connected by threads, which facilitates the later disassembly and replacement of the filter element 6 or the maintenance of the heating tube 401. The hollow design at the bottom of the filter element seat 4 and the snap-fit of the embedded platform of the heating base 3 not only ensure the structural stability, but also realize the rapid installation and power connection of the heating system.
[0040] When maintenance or component replacement is required, the threaded connection between the cylinder 1 and the filter element seat 4 can be directly unscrewed to remove the filter element 6 for cleaning or replacement. If the heating system malfunctions, the filter element seat 4 and the heating base 3 can be quickly separated using the snap-fit structure to inspect the plug 301, the power socket, or the heating tube 401. Throughout the entire operation, the power socket 303 on the rear side of the heating base 3 continuously supplies power to the system, ensuring stable operation of the heating function. Especially in low-temperature environments, through precise temperature control and efficient heating design, the problem of decreased filtration efficiency due to increased oil viscosity is effectively avoided, achieving reliable operation of the oil depot conveying system under different temperature conditions.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
