Description

Technical Field

[0001] This utility model relates to the field of oil filter technology, specifically a vacuum heating oil filter. Background Technology

[0002] An oil filter is a filtration unit that removes solid impurities and moisture from impure oil using pressure filtration or vacuum evaporation-pressure filtration methods.

[0003] Existing vacuum heating oil filters use an air pump to create a near-vacuum state and then remove moisture and impurities from the oil through heating. However, the vacuum tank is generally a single unit, and if any major component inside the vacuum tank is damaged, the vacuum tank will not be able to work properly and will need to be repaired. The repair process is not only cumbersome, but it will also delay the working efficiency of the oil filter. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum heating type oil filter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum heating oil filter, comprising a vacuum tank, a top cover installed at the upper end of the vacuum tank, a primary heating channel installed on the outer side of the top cover via a third pipe, a primary filtration system connected to the primary heating channel via a first pipe, an oil inlet pipe at the other end of the primary filtration system, a first oil outlet pipe installed at the lower end of the vacuum tank, a central pipe connected to the first oil outlet pipe installed at the center of the interior of the vacuum tank, an oil pump installed at the connection between the central pipe and the first oil outlet pipe, multiple partition plates arranged in an equidistant array on the outer wall of the central pipe, the interior of the vacuum tank being divided into multiple vacuum heating chambers by the multiple partition plates, each of the multiple vacuum heating chambers being equipped with a heater, and the bottom of each of the multiple vacuum heating chambers being connected to the central pipe via a pipe.

[0006] Preferably, the lower end of the vacuum heating chamber is rotatably connected to a rotating shaft, and multiple guide plates are longitudinally and equidistantly arrayed on the surface of the rotating shaft.

[0007] Preferably, the lower end of the top cover is equipped with multiple nozzles, each of which is adapted to the position of a multiple vacuum heating chamber, and each of the multiple nozzles is connected to a third pipeline through a valve.

[0008] Preferably, a heating tube is provided at the lower end of the primary heating channel, the upper end of the heating tube is connected to the top cover through a second pipe, a top channel is provided at the center of the lower end of the top cover, the top channel is connected to the second pipe through an air pump, and an air outlet pipe is installed at the other end of the heating tube, the air outlet pipe is connected to an external condenser through an air pump.

[0009] Preferably, the outer end of the first oil outlet pipe is connected in series with three longitudinally distributed fine filters. The uppermost fine filter is connected to an external storage chamber through the second oil outlet pipe, and the filtration mesh size of the three fine filters decreases sequentially from bottom to top.

[0010] Preferably, the primary filtration system includes a primary filter, a secondary filter, and an adsorber. The oil inlet pipe is connected to the primary filter, the primary filter is connected to the adsorber via a pipe, the adsorber is connected to the secondary filter via a pipe, and the secondary filter is connected to the primary heating pipe via a first pipe.

[0011] Preferably, a pulse generator is installed inside the primary filter, secondary filter, and fine filter, and the pulse generator is connected to an external gas storage tank.

[0012] Preferably, the bottom of the vacuum tank is provided with a bottom support, which is located outside the first oil outlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This vacuum heating oil filter divides the vacuum tank into multiple vacuum heating chambers via a central pipe and several partitions. Each vacuum heating chamber is equipped with an independently operating heater and temperature sensor. After the filtered oil enters the vacuum tank, it enters each of the multiple vacuum heating chambers for heating. If any major component in a vacuum heating chamber fails, the valve can be closed to prevent oil from entering, while the other vacuum heating chambers can continue to operate normally. The independent operation of each vacuum heating chamber increases the fault tolerance of the vacuum tank to a certain extent and reduces the frequency of maintenance.

[0015] 2. This vacuum heating type oil filter sprays oil into the vacuum heating chamber through nozzles in the form of spray. The motor drives the rotating shaft and multiple guide plates to rotate, throwing the oil out towards the side wall of the vacuum heating chamber, thereby increasing the contact area between the oil and the vacuum and accelerating the evaporation of moisture.

[0016] 3. This vacuum heating oil filter uses an air pump to extract hot steam from inside the vacuum heating chamber and discharge it into the heating tube. The heating tube then provides initial heating to the primary heating channel above. The oil needs to pass through the primary heating channel before entering the vacuum tank. The collected hot steam provides initial heating to the oil, forming a relatively stable cycle and saving costs. Attached Figure Description

[0023] like Figures 1 to 3As shown, this embodiment of the vacuum heating oil filter includes a vacuum tank 1. A top cover 20 is installed on the upper end of the vacuum tank 1, which seals the vacuum tank 1. A primary heating channel 5 is installed on the outside of the top cover 20 through a third pipe 23. The primary heating channel 5 is connected to a primary filtration system 3 through a first pipe 6. An oil inlet pipe 2 is provided at the other end of the primary filtration system 3. The oil to be filtered enters through the oil inlet pipe 2 and undergoes preliminary filtration of some impurities in the oil by the primary filtration system 3. The pre-filtered oil then enters the first pipe under the action of an oil pump. The oil enters the interior of the 6th heating channel and undergoes preliminary preheating in the primary heating channel 5. The preheated oil then enters the vacuum tank 1 through the third pipe 23. A first oil outlet pipe 11 is installed at the lower end of the vacuum tank 1. The oil, after moisture removal inside the vacuum tank 1, is discharged from the first oil outlet pipe 11 via an oil pump. A central pipe 14, connected to the first oil outlet pipe 11, is installed at the center of the vacuum tank 1. An oil pump is installed at the connection point between the central pipe 14 and the first oil outlet pipe 11. Multiple partition plates 15 are equidistantly arranged on the outer wall of the central pipe 14. The oil then flows through the vacuum tank 1... Multiple partitions 15 divide the space into multiple vacuum heating chambers 19. Oil enters the interior of the multiple vacuum heating chambers 19 through the top cover 20, gradually sinking to the bottom and entering the interior of the central pipe 14. It should be noted that an electric valve is installed between the vacuum heating chambers 19 and the central pipe 14 to control the opening and closing of the channel between the vacuum heating chambers 19 and the central pipe 14. Then, under the action of the oil pump, the oil inside the central pipe 14 will enter the first oil outlet pipe 11 for discharge. Each of the multiple vacuum heating chambers 19 is equipped with a heater 16. The bottom of each of the multiple vacuum heating chambers 19 is connected to the central pipe 14 through a pipe. Each vacuum heating chamber 19 is equipped with an independently operating heater 16 and a temperature sensor. After the filtered oil enters the vacuum tank 1, it enters the multiple vacuum heating chambers 19 for heating. If the main components inside any vacuum heating chamber 19 are damaged, the valve can be closed to prevent oil from entering, while the other vacuum heating chambers 19 can still operate normally. Each vacuum heating chamber 19 operates independently, which increases the fault tolerance of the vacuum tank 1 to a certain extent and reduces the frequency of maintenance.

[0024] Specifically, a rotating shaft 17 is rotatably connected to the lower end of the vacuum heating chamber 19. Multiple guide plates 18 are longitudinally and equidistantly arranged on the surface of the rotating shaft 17. A motor is installed at the bottom of the rotating shaft 17 and inside the vacuum tank 1. The motor is connected to the rotating shaft 17. The motor drives the rotating shaft 17 and the multiple guide plates 18 to rotate, throwing the oil towards the side wall of the vacuum heating chamber 19 to increase the contact area between the oil and the vacuum and accelerate the evaporation of moisture.

[0025] Furthermore, multiple nozzles 21 are installed at the lower end of the top cover 20. The multiple nozzles 21 are respectively adapted to the positions of multiple vacuum heating chambers 19. The multiple nozzles 21 are all connected to the third pipe 23 through valves. The oil enters the interior of the top cover 20 through the third pipe 23, and then is sprayed into the interior of the multiple vacuum heating chambers 19 through the multiple nozzles 21 in a spray manner. The spray can increase the contact area between the oil and the vacuum, and accelerate the evaporation of water.

[0026] Furthermore, a heating pipe 8 is provided at the lower end of the primary heating channel 5. The upper end of the heating pipe 8 is connected to the top cover 20 through the second pipe 7. A top channel 22 is opened at the center of the lower end of the top cover 20. The top channel 22 is connected to the second pipe 7 through an air pump. An exhaust pipe 9 is installed at the other end of the heating pipe 8. The exhaust pipe 9 is connected to the external condenser through the air pump. The air pump will extract the hot steam inside the vacuum heating chamber 19 and enter the interior of the second pipe 7 through the top channel 22, and finally enter the interior of the heating pipe 8. Then it will be discharged from the exhaust pipe 9 at the other end of the heating pipe 8. The air pump extracts the hot steam inside the vacuum heating chamber 19 and discharges it into the interior of the heating pipe 8. The heating pipe 8 provides preliminary heating to the primary heating channel 5 above. The oil needs to enter the interior of the vacuum tank 1 through the primary heating channel 5. The collected hot steam provides preliminary heating to the oil, forming a relatively stable cycle and saving costs.

[0027] Furthermore, three longitudinally distributed fine filters 12 are connected in series at the outer end of the first oil outlet pipe 11. The uppermost fine filter 12 is connected to the external storage chamber through the second oil outlet pipe 13. The filtration mesh size of the three fine filters 12 decreases sequentially from bottom to top. The oil discharged from the vacuum tank 1 will be filtered by the three fine filters 12 in sequence. The filtration effect of the three fine filters 12 increases sequentially, thereby intercepting impurities in the oil step by step.

[0028] Furthermore, the primary filtration system 3 includes a primary filter 301, a secondary filter 302, and an adsorber 303. The oil inlet pipe 2 is connected to the primary filter 301. The primary filter 301 is connected to the adsorber 303 through a pipe. The adsorber 303 is connected to the secondary filter 302 through a pipe. The secondary filter 302 is connected to the primary heating pipe 8 through the first pipe 6. The primary filter 301 and the secondary filter 302 have the same structure and filter impurities in the oil through a screen. The adsorber 303 is installed between the primary filter 301 and the secondary filter 302. The adsorber 303 is equipped with activated alumina inside, which can adsorb dissolved gases and trace amounts of moisture inside.

[0029] Furthermore, pulse generators are installed inside the primary filter 301, secondary filter 302, and fine filter 12. The pulse generators are connected to an external air tank 4. The pulse generators generate short, high-speed airflows using compressed air, which can remove impurities adsorbed inside the primary filter 301, secondary filter 302, and fine filter 12. The start and stop of the pulse airflow are controlled by a solenoid valve. The pulse generator is a mature existing technology and will not be described in detail. A bottom support 10 is provided at the bottom of the vacuum tank 1. The bottom support 10 is located outside the first oil outlet pipe 11 and can provide a certain support effect.

[0030] The usage method of this embodiment is as follows: the oil enters the primary filtration system 3 through the oil inlet pipe 2 for preliminary filtration. The filtered oil enters the primary heating channel through the first pipe 6 for preheating. The preheated oil enters the vacuum heating chamber 19 through the top cover 20 of the third pipe 23 and is sprayed through multiple nozzles 21 for heating. The water vapor generated after heating enters the heating pipe 8 through the second pipe 7 and heats the primary heating channel 5 through the heating pipe 8. At the same time, the oil inside the vacuum heating chamber 19 is heated by the heater 16 inside the vacuum tank 1. The heater 16 is a common electric heater 16. Finally, the oil is discharged through the central pipe 14 and the first oil outlet pipe 11 under the action of the oil pump. It then enters the three fine filters 12 for filtration in sequence. Finally, the filtered oil is discharged and stored through the second oil outlet pipe 13.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
