Background Technology

[0003] Most known oil recovery units include an evaporation chamber so that moisture is evaporated when the oil is heated.

[0004] However, these known units, systems, and devices have many structural drawbacks, as none of the known systems can achieve optimal evaporation performance in an economically viable system.

[0005] Therefore, oil recovery units that can efficiently evaporate water from oil (preferably efficient and reliable units) will have advantages, especially more durable, economical and sustainable oil recovery units with long service life. Summary of the Invention

[0006] The purpose of this invention is to provide a recycling unit that can efficiently remove moisture from liquids (e.g., oil) with low energy consumption, while reducing the risk of damage caused by overheating of the liquid.

[0007] Specifically, one object of the present invention is to provide a recovery unit that can improve the evaporation effect of oil in an evaporation chamber.

[0008] Another object of the present invention is to provide an alternative to the prior art.

[0009] This can be achieved through a recovery unit with a ventilated evaporation unit.

[0010] Invention Description

[0011] Therefore, a first aspect of the present invention aims to achieve the above-mentioned objective and several other objectives by providing an oil recovery unit comprising: Housing, the housing comprising: Filter unit, An evaporator chamber having at least one sidewall Heating source, such as heating unit, Oil pump unit used to generate oil flow, A ventilation system, the ventilation system comprising at least: Air intake, and Air outlet.

[0012] The present invention particularly, but not exclusively, provides an oil recovery unit in which water is evaporated, for example, separated from the oil, by ventilating the evaporation chamber.

[0013] The humidity was reduced by ventilating the evaporation chamber.

[0014] Compared to not ventilating the evaporation chamber, ventilating the evaporation chamber can increase the evaporation of water by two, four, six, eight, or even more than ten times.

[0015] In the context of this invention, "unit" can be understood as a system, device, and / or similar object.

[0016] In the context of this invention, "ventilation" can be understood as providing an airflow.

[0017] In the context of this invention, "air" can be understood as air at any temperature, such as air below 100 degrees Celsius, and / or air above 100 degrees Celsius (e.g., steam).

[0018] In one embodiment of the invention, during use, an airflow from a fan device is provided at the air inlet.

[0019] In one embodiment of the invention, the ventilation system is configured to ventilate the evaporator chamber during use.

[0020] This embodiment is particularly, but not exclusively, advantageous for enhancing and thereby improving the evaporation of water in the oil within the evaporation chamber.

[0021] In one embodiment of the present invention, during use, the air outlet is a steam outlet for discharging steam.

[0022] This embodiment is particularly advantageous, but not exclusively, for utilizing the overpressure / positive pressure within the evaporation chamber to expel steam from the evaporation chamber through the outlet.

[0023] In one embodiment of the present invention, the system further includes: The motor of the oil pump, such as the motor axle and / or motor shaft.

[0024] In one embodiment of the present invention, the system further includes: The fan assembly is preferably located inside the fan housing.

[0025] This embodiment is particularly, but not exclusively, advantageous in providing a ventilation system that includes a fan device, which is a relatively simple device but can provide highly effective ventilation for the oil recovery unit.

[0026] In one embodiment of the invention, the fan assembly includes an impeller and / or a propeller, and / or a fan wheel, and / or is provided by a fan segment cut from a motor.

[0027] This embodiment is particularly, but not exclusively, advantageous in providing a fan device suitable for inclusion in an oil recovery unit and for ventilating the evaporation chamber within the oil recovery unit.

[0028] Meanwhile, the fan unit is provided as a compact component of the ventilation system.

[0029] In one embodiment of the invention, the ventilation system is at least partially, preferably entirely, driven by the action of a motor.

[0030] This embodiment is particularly, but not exclusively, advantageous in providing a ventilation system that is both cost-effective and environmentally friendly.

[0031] By utilizing the effects produced by a continuously running motor, such as the energy of a running motor or the ventilation / airflow effect, no additional energy supply is required. An external energy supply is not mandatory. However, it should be understood that the invention can also be implemented with an external energy supply if necessary.

[0032] Preferably, the ventilation system or a portion thereof is included within the oil recovery unit.

[0033] In one embodiment of the invention, the fan assembly and / or fan housing are integrated components of the clutch housing.

[0034] This embodiment is particularly, but not exclusively, advantageous for saving space in the recycling unit.

[0035] In one embodiment of the invention, the fan device is configured to be associated with the motor of the oil pump, and / or disposed on the motor of the oil pump.

[0036] This embodiment is particularly, but not exclusively, advantageous for optimizing the use of energy provided by the motor. It also optimizes the use of space.

[0037] In one embodiment of the present invention, the fan device includes: Fan inlet, and Fan outlet.

[0038] This embodiment is particularly, but not exclusively, advantageous in providing an apparatus in which outside air can be drawn in through a fan inlet, blown out through a fan outlet, and continued to be delivered from the fan outlet, preferably via a duct.

[0039] In one embodiment of the invention, the oil recovery unit includes a storage tank.

[0040] This embodiment is particularly, but not exclusively, advantageous for assembling a reservoir (e.g., a storage tank), thus eliminating the direct return of oil to the oil reservoir by gravity. This, along with the airflow through the evaporator chamber, serves to keep the evaporator chamber ventilated to the atmosphere.

[0041] Depending on the filtration capacity, the accumulator comes in various sizes, but it typically has sufficient spare capacity to fully accommodate the oil drained from the filter elements on the system. Because the filter is fitted with an oil exit port facing downwards toward the evaporation chamber, oil will drain out from the filter insert when the unit is shut down.

[0042] In one embodiment of the invention, the fan outlet is in fluid communication with the air inlet.

[0043] This embodiment particularly, but not exclusively, benefits from providing a ventilation system in which air blown out through a fan outlet can be directed upwards to the air inlet of an oil recovery unit. Preferably, the fan outlet is connected to a duct, preferably via a fitting, which is also connected to the oil recovery unit, for example, to the unit's storage tank, or for example, to an evaporation chamber.

[0044] In one embodiment of the invention, during use, an airflow is provided between the fan and the air inlet, preferably the airflow is delivered from the fan outlet to the air inlet through at least one duct.

[0045] When the unit includes a storage tank, ventilation is naturally ensured by blowing air in through pipes. To enhance moisture evaporation, a small amount of ambient air can be blown in through an air inlet located at the top of the storage tank to provide forced ventilation for the oil recovery unit.

[0046] It should be understood that in systems without a storage tank, air can also be blown directly into the evaporation chamber.

[0047] In one embodiment of the invention, the airflow is provided by one or more integrated air sources.

[0048] In one embodiment of the present invention, the unit includes: Ventilation filters, preferably in-line filters (duct filters).

[0049] This embodiment is particularly, but not exclusively, advantageous in ensuring that the ventilation system does not contaminate the filtered oil. By incorporating a ventilation filter, any contaminants that may be present in the air can be removed before the ventilation air comes into contact with the oil in the evaporation chamber.

[0050] In one embodiment of the invention, the ventilation filter is connected to, or in relation to, a duct that delivers airflow.

[0051] This embodiment is particularly, but not exclusively, advantageous for optimal filtration of any potential contaminants.

[0052] In one embodiment of the invention, the ventilation filter is mounted on the recycling unit via at least one bracket (preferably two or more brackets).

[0053] This embodiment particularly, but not exclusively, facilitates easy installation / attachment of the filter. For example, when maintenance or replacement of the filter is required, the filter can be easily attached to and / or removed from the bracket.

[0054] The following description uses the recovery unit as a specific embodiment and describes it as an oil recovery unit. However, it should be noted that the recovery unit can also be applied to other liquids that require the removal of solid contaminants and moisture.

[0055] The recovery unit includes a housing having a removable upper and lower portion, wherein the lower portion is connected to a base portion, the base portion including at least one heating unit and multiple inlets and outlets, wherein the upper portion contains a filter unit, and the lower portion and the base portion form an evaporation chamber. Therefore, this recovery unit is of the type where the filter unit is located on top of the evaporation chamber, which has the advantage that, under gravity, the oil automatically flows downwards, and only a small amount of oil remains in the filter unit when the recovery unit is not in use or is disposed of.

[0056] Because the heating unit extends into the evaporator chamber and has no conductive contact with the sidewalls, and the partition plate pushes the oil outwards onto the sidewalls of the evaporator chamber, the heating unit never comes into contact with the oil film on the sidewalls. Therefore, the oil is heated by convective heat transferred to the enclosed atmosphere within the evaporator chamber, allowing only the surface of the oil film to be heated. Consequently, the evaporation process in this recovery unit uses very little heat, as there is no need to heat the evaporator chamber walls to prevent condensation of the generated vapors. Heating the evaporator chamber walls would result in a significant loss of heat to the surrounding environment and would also cause additional heating to the oil in the process.

[0057] The evaporation process in this recovery unit is achieved through a central heating unit that heats the atmosphere within the evaporation chamber via convection. The surface temperature and surface area of ​​the heating unit can be adjusted to reduce the generation of radiant heat, which heats the oil flowing within the evaporation chamber and causes heat loss. Only convective heat transfer from the hot atmosphere within the evaporation chamber to the surface of the oil film flowing on the chamber wall is required to promote the evaporation of water from the oil.

[0058] Furthermore, when the heating unit is not in contact with the sidewall of the evaporation chamber, the surrounding environment will maintain the sidewall temperature of the evaporation chamber at a temperature lower than the atmospheric temperature inside the evaporation chamber due to conductivity. Therefore, there is no high energy loss from the recovery unit to the surrounding environment, and the risk of oil overheating is also significantly reduced.

[0059] In a second aspect, the present invention also relates to a ventilation method for an oil recovery unit, preferably an oil recovery unit according to any one of the preceding claims, wherein the method comprises the following steps: Provide oil recovery units, The oil recovery unit is started by activating the oil pump. A ventilation system is provided for ventilating the oil recovery unit, preferably an integrated ventilation system, which includes at least: Air intake, and Air outlet, Air is preferably drawn in through the fan air inlet of the fan device. An airflow is provided, which preferably flows at least partially through a duct and / or through a filter. The oil recovery unit is ventilated through an air outlet, preferably through the evaporator chamber of the unit. The ventilation system is at least partially, and preferably entirely, driven by a motor. The steps of this method can be executed in any order and / or simultaneously.

[0060] A second aspect of the invention is particularly, but not exclusively, advantageous in providing a method for optimizing water evaporation in an oil recovery unit, wherein evaporation of water, for example, separation of water from oil, can be improved by ventilating the evaporation chamber. Compared to not ventilating the evaporation chamber, this method of ventilating the evaporation chamber can increase water evaporation by two, four, six, eight, or even more than ten times.

[0061] The first and second aspects of the present invention can be combined with any other aspects. These and other aspects of the present invention will be explained and clearly demonstrated with reference to the embodiments described below.

[0062] The embodiments of the system should be considered applicable to the method, and the embodiments of the method should also be considered applicable to the product / system. Attached Figure Description

[0076] The illustrated oil recovery unit is suitable for performing a ventilation method (not shown) for an oil recovery unit, wherein the method includes the following steps: Provide oil recovery unit 100, The oil recovery unit 100 is started by activating the oil pump 500. A ventilation system is provided for the oil recovery unit 100 to ventilate the unit. This ventilation system is preferably an integrated ventilation system, and includes at least the following components: Air inlet 610, and Air outlet 620, Preferably, air is drawn in through the fan air inlet 810 of the fan device 800. An airflow 900 is provided, which preferably flows at least partially through duct 650 and / or through filter 680. The oil recovery unit 100 is ventilated through air outlet 620, preferably through the evaporator chamber 300 of the unit. The ventilation system 600 is at least partially, and preferably entirely, driven by the motor 700. The steps of this method can be executed in any order and / or simultaneously.

[0077] Figure 1 b shows an exploded view of the recycling unit. It should be understood that this diagram is a very simplified schematic.

[0078] Figure 1 b illustrates the various parts of the recovery unit 100, including the upper and lower portions of the housing 200, which can be connected in an airtight manner. The housing 200 contains a filter unit 250. The lower portion of the housing 200 includes an evaporator chamber 300.

[0079] Figure 2 A three-dimensional view of the motor and fan assembly is shown.

[0080] exist Figure 2In the process, a fan assembly 800 is located within a fan housing. The fan assembly 800 includes a fan wheel, and may also include an impeller and / or a propeller, and / or is provided by a fan segment cut from a motor.

[0081] also, Figure 2 The diagram also shows an oil pump unit 500 for generating oil flow, a motor 700 of the oil pump unit 500 (e.g., motor wheel axle and / or motor shaft), and a clutch housing 850.

[0082] The illustrated structure is suitable for providing an airflow (not shown). In this invention, preferably, the airflow is provided by one or more integrated air sources, such as motor 700.

[0083] Figure 2 The image also shows a fan assembly 800, which includes: Fan imported 810, and Fan outlet 820, The fan device 800 is configured to be associated with the motor 700 of the oil pump unit 500, and / or configured on the motor 700 of the oil pump unit 500.

[0084] exist Figure 2 In this configuration, the fan assembly is directly mounted on the motor shaft and driven by the motor shaft.

[0085] Figure 3 The recycling unit is shown equipped with two motors and a ventilation system.

[0086] Figure 3 Figure ab shows that the fan outlet 820 is in fluid communication with the air inlet 610. In the figure, this communication is achieved through a conduit, through which an airflow 900 is provided between the fan assembly 800 and the air inlet 610 during use. Preferably, the airflow 900 is delivered from the fan outlet 820 to the air inlet 610 through at least one conduit 650.

[0087] exist Figure 3 In the illustration, the oil recovery unit 100 is equipped with one or more active air fan devices 800, which are mounted on the shaft of the existing motor 700 to ventilate the evaporation chamber 300. This allows for a multiplying increase in evaporation efficiency without requiring additional energy. This solution is applicable to numerous systems and units that utilize the evaporation chamber principle to filter particulate matter and moisture.

[0088] The oil recovery unit 100 can be equipped with a storage tank 350, thus preventing the oil from being directly returned to the oil reservoir by gravity. This structure, along with the airflow through the evaporator chamber 300, is used to keep the evaporator chamber ventilated to the atmosphere. When the storage tank 350 is installed, the oil return pump delivers the oil back to the system.

[0089] To facilitate installation, the space requirements were optimized as much as possible. The unit can be mechanically installed through holes in the base plate. Support lugs are provided at the top to mitigate the effects of vibration.

[0090] Depending on the filter capacity, the accumulator 350 can come in various sizes, but it typically has enough spare capacity to fully hold the oil discharged from the filter on the unit.

[0091] This unit prioritizes maintainability. Preferably, all components, such as pumps, motors, sensors, valves, and heating coils, can be replaced to varying degrees without requiring the removal of other components besides those discussed.

[0092] The structure and components vary depending on the size of the unit, the application, and the available supply.

[0093] The chassis is a one-piece welded stainless steel structure.

[0094] Depending on the application and size, the unit can be equipped with one, two, or more 700 motors. The motors are selected to have optimized torque and current performance to match the required size of the pump, with a focus on oil at low temperatures.

[0095] When 350 is conveyed as part of the illustrated unit, ventilation is naturally ensured by air supply through air outlet 620. To enhance moisture evaporation, the oil recovery unit 100 provides ventilation by blowing in a small amount of ambient air through air inlet 610. Figure 3 In this case, the air inlet is located at the top of the storage tank.

[0096] It should be understood that in units without a storage tank 350, air can be blown directly into the evaporation chamber 300.

[0097] If necessary, a check valve 550 can be installed at the pump outlet of pump 500. This prevents system oil from entering the filter when the filter unit is shut down.

[0098] Figure 4 A cross-section of the evaporation chamber 300 is shown, in which the ventilation system is clearly shown, which includes at least: Air inlet 610, and Air outlet 620, In addition, the figure also shows a coil that serves as a heating unit 400 in the evaporation chamber.

[0099] Figure 5 An embodiment of the ventilation filter 680 is shown.

[0100] In this invention, air can be supplied by an integrated centrifugal pump 500 located in the clutch housing 850, which can be connected in series when a return pump is installed. The clutch housing has an air inlet and an air outlet.

[0101] The air fan housing 800 can be an integrated component of the clutch housing.

[0102] Air is preferably filtered in a ventilation filter 680, which is preferably shown as a replaceable in-line filter. The filter is preferably mounted via one or more brackets 685, which also facilitate the removal of the air filter housing.

[0103] Preferably, each connector is a one-touch fitting 690 that is easy to assemble and disassemble. The ventilation filter 680 is installed at the duct 650 or associated with the duct that delivers the airflow.
