Description

Technical Field

[0001] This utility model relates to the field of vehicle filtration technology, specifically to a vehicle filter. Background Technology

[0002] In many industrial sectors such as petroleum, chemical, and energy, oil often becomes contaminated with various impurities during production, storage, transportation, and loading, such as mechanical impurities, moisture, and particulate matter. The presence of these impurities can have many adverse effects on subsequent processes, equipment operation, and product quality.

[0003] During the oil loading process, impurities in the oil can cause blockages in the loading pipelines, affecting loading efficiency and even interrupting the loading operation. Impurities entering the oil transport vehicle can also cause wear and tear on vehicle components due to vibration and bumps during transport, shortening equipment lifespan. For applications with extremely high oil quality requirements, such as aviation fuel and precision instrument oils, the presence of impurities can severely affect oil performance indicators, leading to substandard product quality and potentially causing safety accidents or significant economic losses. Traditional oil filtration methods require frequent shutdowns for filter replacement or cleaning after a period of time due to filter screen clogging. This is cumbersome, time-consuming, and labor-intensive, resulting in low filtration efficiency. Utility Model Content

[0004] This utility model provides a vehicle filter to solve the problem of low filtration efficiency caused by frequent replacement and cleaning of filter elements due to filter screen clogging in existing filtration equipment.

[0005] To address the aforementioned problems, this utility model provides a vehicle-mounted filter, comprising: a filter canister, a filter cartridge disposed inside the filter canister, an oil inlet pipe disposed on the bottom side wall of the filter canister and connected to the filter cartridge, an oil outlet pipe disposed on the upper side wall of the filter canister and located at the top of the filter cartridge, an oil collection tank connected to the filter canister via a waste oil pipe disposed at the bottom of the filter canister, and an oil collection pipe disposed on the bottom side wall of the oil collection tank; further comprising: an inner filter cartridge disposed inside the filter cartridge, an outer metal cylinder connected to the inner filter cartridge via a sealed bearing and fixed to the inner wall of the filter canister, a rotating shaft connected to the inner filter cartridge via a bearing, a turbine fixed at one end of the rotating shaft, a detachable metal plate disposed at the bottom of the inner filter cartridge, and an opening of the outer metal cylinder located at the bottom of the filter canister;

[0006] The above solution, with its inverted double-layer filter cartridges and low-speed rotating turbine, allows the oil to pass through two layers of filter screens after centrifugal separation, thus avoiding the problem of frequent filter element replacement and cleaning required by traditional filtration equipment. This reduces maintenance costs and manpower, improves filtration efficiency, and enables the vehicle-mounted filter to operate more stably and efficiently, ensuring the quality and speed of oil filtration and meeting the needs of vehicle loading operations.

[0007] According to one embodiment of the present invention, the oil outlet pipe is provided with a nitrogen backflush pipe. Through the above scheme, after the nitrogen backflush pipe is connected to the oil outlet pipe, the backflush effect of nitrogen can be used to clean the filter screen inside the filter cartridge in reverse, effectively removing impurities and blockages attached to the filter screen, restoring the filtration performance of the filter screen, and reducing the problem of decreased filtration efficiency caused by filter screen blockage.

[0008] According to one embodiment of the present invention, the upper side wall of the oil collection tank is provided with an exhaust pipe. After the exhaust pipe is installed, the gas generated during nitrogen purging can be discharged in time, maintaining the pressure balance inside and outside the oil collection tank, and preventing equipment damage or affecting the normal collection of waste oil due to excessive pressure.

[0009] According to one embodiment of the present invention, the oil outlet pipe is equipped with a bidirectional explosion-proof oil pump. Through the above solution, the oil pump has bidirectional conveying capability and meets the requirements of forward and reverse operation. It can effectively prevent the risk of explosion caused by electrical sparks or mechanical friction and is suitable for flammable and explosive oil conveying environments.

[0010] According to one embodiment of this utility model, the above-mentioned oil inlet pipe, oil outlet pipe, waste oil pipe, oil collection pipe, nitrogen backflush pipe, and exhaust pipe are all equipped with electric valves. During the loading process, the valves of the corresponding pipes can be automatically opened / closed according to the type of oil or loading requirements, reducing human operation errors. In case of abnormality, the electric valves can respond quickly and automatically close the relevant pipes to prevent the accident from escalating.

[0011] According to one embodiment of the present invention, the pipe axis of the oil inlet pipe is at an angle of 0-5° to the tangential direction of the outer wall of the filter cartridge. Through the above scheme, the oil flows into the filter cartridge in the tangential direction, generating thrust on the turbine to form a swirling flow field, further accelerating the separation of oil and impurities and improving the filtration effect.

[0012] According to one embodiment of the present invention, the outer metal cylinder and the inner filter cylinder are configured as inverted conical cylinders. With the above scheme, the shape of the inverted conical cylinder makes it easier for impurities trapped by the filter screen to accumulate at the bottom of the filter cylinder under the action of gravity. Since the bottom space is relatively small and is located in the convergence area of ​​fluid flow, impurities are not easy to stay and accumulate on the surface of the filter screen for a long time, reducing the risk of filter screen blockage and reducing the problem of decreased filtration performance caused by impurity deposition.

[0013] According to one embodiment of this utility model, the inner filter cartridge sidewall filter screen is set to 80 mesh, and the top filter screen is set to 100 mesh. Through the above scheme, the combination of filter screens with different mesh sizes forms a graded filtration structure. The 80 mesh filters on both sides can initially intercept relatively large-diameter impurities. After interception, the fluid passes through the top 100 mesh filter screen again to further finely filter the fine impurities in the fluid, effectively retaining the smaller-diameter impurities, improving the overall filtration accuracy, and making the filtered fluid of higher quality.

[0014] The technical advantages of this application are as follows:

[0015] This application provides a vehicle-mounted filter with an inverted double-layer filter cartridge and a low-speed rotating turbine. This allows the oil to pass through two layers of filter screens after centrifugal separation, thus avoiding the problem of filter screen clogging and frequent filter element replacement and cleaning required by traditional filtration equipment. This reduces maintenance costs and manpower input, improves filtration effect, and enables the vehicle-mounted filter to operate more stably and efficiently, ensuring the quality and speed of oil filtration and meeting the needs of vehicle loading operations.

Detailed Implementation

[0019] The following will be combined with the appendix Figure 1 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to illustrate the technical solution of this application more clearly, and are therefore only examples and should not be used to limit the scope of protection of this application.

[0020] Reference Figure 1This utility model provides a vehicle-mounted filter, comprising: a filter canister 1, a filter cartridge 101 disposed inside the filter canister 1, an oil inlet pipe 102 disposed on the bottom side wall of the filter canister 1 and connected to the filter cartridge 101, an oil outlet pipe 103 disposed on the upper side wall of the filter canister 1 and located at the top of the filter cartridge 101, an oil collection tank 2 connected to the filter canister 1 via a waste oil pipe 105 disposed at the bottom of the filter canister 1, and an oil collection pipe 201 disposed on the bottom side wall of the oil collection tank 2; further comprising: a filter cartridge 102 disposed on the bottom side wall of the filter cartridge 101, the filter cartridge 103 disposed on the top side wall of the filter cartridge 101, the filter cartridge 102 disposed on the bottom ... The filter cartridge 101 has an inner filter cartridge 1014 inside, an outer metal cartridge 1011 connected to the inner filter cartridge 1014 by a sealed bearing and fixed to the inner wall of the filter tank 1, a rotating shaft 1015 that is connected to the inner filter cartridge 1014 by a bearing, a turbine 1012 fixed at one end of the rotating shaft 1015, a detachable metal plate 1013 at the bottom of the inner filter cartridge 1014, and the opening of the outer metal cartridge 1011 is located at the bottom inside the filter tank 1.

[0021] The inverted design of the double-layer filter cartridge 101, combined with the low-speed rotating turbine 1012, allows the oil to pass through two layers of filter screens after centrifugal separation to filter impurities. This avoids the problem of filter screen clogging and frequent filter element replacement and cleaning required by traditional filtration equipment, reducing maintenance costs and manpower input, improving filtration effect, and enabling the vehicle-mounted filter to operate more stably and efficiently, ensuring the quality and speed of oil filtration, and meeting the needs of vehicle loading operations.

[0022] The oil outlet pipe 103 is equipped with a nitrogen backflush pipe 104. After the nitrogen backflush pipe 104 is connected to the oil outlet pipe 103, the backflush effect of nitrogen can be used to clean the filter screen inside the filter cartridge 101 in reverse, effectively removing impurities and blockages attached to the filter screen, restoring the filter screen's filtration performance, and reducing the problem of decreased filtration efficiency caused by filter screen blockage.

[0023] The upper side wall of the oil collection tank 2 is equipped with an exhaust pipe 202. After the exhaust pipe 202 is installed, the gas generated during nitrogen purging can be discharged in time, maintaining the pressure balance inside and outside the oil collection tank 2, and preventing equipment damage or affecting the normal collection of waste oil due to excessive pressure.

[0024] The aforementioned oil outlet pipe 103 is equipped with a bidirectional explosion-proof oil pump 106. The oil pump has bidirectional conveying capability and meets the requirements of forward and reverse operation. It can effectively prevent the risk of explosion caused by electrical sparks or mechanical friction and is suitable for flammable and explosive oil conveying environments.

[0025] The aforementioned oil inlet pipe 102, oil outlet pipe 103, waste oil pipe 105, oil collection pipe 201, nitrogen backflush pipe 104, and exhaust pipe 202 are all equipped with electric valves. During the loading process, the valves of the corresponding pipes can be automatically opened / closed according to the type of oil or loading requirements, reducing human operation errors. In case of abnormality, the electric valves can respond quickly and automatically close the relevant pipes to prevent the accident from escalating.

[0026] The pipe axis of the oil inlet pipe 102 is at an angle of 0-5° to the tangent direction of the outer wall of the filter cartridge 101. Through the above scheme, the oil flows into the filter cartridge 101 in the tangential direction, generating thrust on the turbine 1012 to form a swirling flow field, further accelerating the separation of oil and impurities and improving the filtration effect.

[0027] The outer metal cylinder 1011 and the inner filter cylinder 1014 are designed as inverted conical cylinders. With the above design, the shape of the inverted conical cylinder makes it easier for impurities trapped by the filter screen to accumulate at the bottom of the filter cylinder 101 under the action of gravity. Since the bottom space is relatively small and is located in the convergence area of ​​fluid flow, impurities are not easy to stay and accumulate on the surface of the filter screen for a long time, reducing the risk of filter screen blockage and reducing the problem of decreased filtration performance caused by impurity deposition.

[0028] The inner filter cartridge 1014 has an 80-mesh sidewall filter and a 100-mesh top filter. Through this scheme, the combination of filter screens with different mesh sizes forms a graded filtration structure. The 80-mesh filters on both sides can initially intercept relatively large-diameter impurities. After interception, the fluid passes through the top 100-mesh filter again for further fine filtration of fine impurities in the fluid, effectively retaining smaller-diameter impurities, improving the overall filtration accuracy, and making the filtered fluid of higher quality.

[0029] Working principle:

[0030] Oil enters from the bottom side wall of filter tank 1 through inlet pipe 102 and flows tangentially into outer metal cylinder 1011. The slow flow of oil drives the blades of turbine 1012, causing inner filter cylinder 1014 to rotate at low speed. During the rotation of the oil, it is subjected to centrifugal force. Since the density of impurities in the oil is greater than that of the oil, the greater the density of the substance, the greater the centrifugal force. Therefore, the denser impurities are thrown to the inner wall of outer metal cylinder 1011 and descend with the swirling flow to the conical bottom outlet. The oil after preliminary solid-liquid separation forms a spiraling upward inner swirling flow. After preliminary solid-liquid separation, the oil flows from bottom to top within inner filter cylinder 1014 after passing through the side wall filter screen. It is then filtered through the filter layer at the top of inner filter cylinder 1014. The two filter layers with different mesh sizes intercept more impurities and particles in the oil, resulting in clean oil. The filtered clean oil collects above the filter cartridge 101 and flows out through the upper oil outlet pipe 103, entering the subsequent loading process. During this process, the bidirectional explosion-proof oil pump 106 provides delivery power as needed to ensure stable and efficient oil flow. During filtration, impurities generated by the inverted conical inner filter cartridge 1014 fall onto the detachable metal plate 1013 due to gravity, while waste oil and impurities generated within the interlayer of the inverted conical filter cartridge 101 fall to the bottom of the filter tank 1 due to gravity and swirling action, flowing into the oil collection tank 2 through the waste oil pipe 105 at the bottom of the filter tank 1. The waste oil is collected in the oil collection tank 2 and further processed or recycled through the oil collection pipe 201.

[0031] When the filter screen of filter cartridge 101 becomes clogged or requires cleaning, the metal plate is disassembled and cleaned. A nitrogen backflush pipe 104 is connected to the oil outlet pipe 103 to introduce nitrogen into the system. The nitrogen enters filter cartridge 101 in reverse through the nitrogen backflush pipe 104, performing reverse cleaning of the filter screen. The high-pressure nitrogen flow can blow away impurities and blockages adhering to the filter screen, restoring its filtration performance. Gas generated during the cleaning process is promptly discharged through the exhaust pipe 202 on the upper side wall of the oil receiving tank 2, maintaining pressure balance inside and outside the oil receiving tank 2.

[0032] All pipelines are equipped with electric valves, which can automatically open or close the valves of the corresponding pipelines according to the type of oil or loading requirements, reducing human error. The bidirectional explosion-proof oil pump installed on the oil outlet pipe 103 can meet the requirements of forward and reverse operation, effectively preventing the risk of explosion caused by electrical sparks or mechanical friction, and providing safety assurance for oil transportation.
