Description

Technical Field

[0001] The invention relates to a filtering device used in the production of shock absorber oil for new energy vehicles, belonging to the field of filtering devices for producing shock absorber oil. Background Art

[0002] Shock absorbers are an important mechanical device in new energy vehicles. During the driving process of the vehicle, shock absorbers can absorb bumps and shocks from the road, reduce vibrations, and make driving more stable and comfortable. Shock absorber oil is indispensable in the shock absorber. When the shock absorber piston moves in the cylinder, the shock absorber oil needs to pass through the small holes or valves on the piston. When the oil flows through these narrow channels, it will generate resistance. This resistance is the damping force. For example, when a vehicle is driving on a bumpy road, the shock absorber piston moves up and down quickly. The damping force of the shock absorber oil can effectively suppress the excessive vibration of the vehicle body caused by the spring rebound, so that the vibration of the vehicle is attenuated.

[0003] Shock absorber oil requires suitable viscosity, good anti-wear performance, excellent anti-oxidation performance, and good low-temperature fluidity. Most shock absorber oils are mineral oil shock absorber oils and synthetic shock absorber oils.

[0004] During the production process, shock absorber oil is viscous and easily solidifies in low-temperature winter conditions. In addition, filtering solid impurities in the shock absorber oil can easily cause the filter to become clogged, making it impossible to achieve the purpose of filtering. If additional large-scale heating equipment is used to heat the shock absorber oil, the temperature cannot be controlled and it is easy to volatilize when the temperature is too high. The hydrocarbons volatilized from the shock absorber oil will enter the atmosphere, increasing the content of volatile organic compounds in the air. These volatile organic compounds will participate in photochemical reactions and, under the action of sunlight, will undergo a series of complex chemical reactions with pollutants such as nitrogen oxides to generate secondary pollutants such as ozone and peroxyacetyl nitrate.

[0005] Therefore, the present invention provides a shock absorber oil filtering device integrating heating and filtering. Summary of the invention

[0006] In view of this, an object of the present invention is to provide a shock absorber oil filtering device integrating heating and filtering.

[0007] The present invention is achieved in that:

[0008] A filtering device used in the production of shock absorber oil for new energy vehicles comprises a first shell, a second shell, a filter column, and a heating unit.

The filter column and the heating unit are positioned relative to each other so that the filter column and the heating unit are matched and connected after the first shell and the second shell are connected.

[0009] As a further improvement, the filter column comprises a flow cavity opened in the center of the filter column and extending vertically;

[0016] A heat conducting plate and balls, wherein the heat conducting plate contacts the heating wire and is locked on the inner surface of the first shell. A plurality of balls are embedded on one end surface of the heat conducting plate, and the number of the balls is equal to the number of the connecting ports, so that the balls cooperate with the connecting ports to connect the heat conducting wire, and the balls separate from the connecting ports to disconnect the heat conducting wire.

[0017] As a further improvement, the second shell further includes a liquid inlet pipe arranged at a preset angle B on the outer surface of the second shell, wherein the preset angle B is 30-60°, and the preset angle B is the angle between the tangent of the outer surface of the second shell and the liquid inlet pipe.

[0018] As a further improvement, the space between the inner surface of the second shell and the filter column is a accommodating chamber for shock absorber oil.

[0019] As a further improvement, it also includes an exhaust pipe. The top of the first shell is provided with an exhaust outlet, and the exhaust outlet is connected to the exhaust pipe to exhaust volatile gases generated by the equipment.

[0020] As a further improvement, it also includes a three-way valve, a first discharge pipe and a second discharge pipe. The three-way valve is connected to the inner center of the second shell and is connected to the connection port at the bottom end of the filter column. The three-way valve can also be directly connected to the second shell. The other two ends of the three-way valve are respectively connected to the first discharge pipe and the second discharge pipe.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] Reference Figure 1-Figure 8 As shown, this embodiment provides a specific implementation method for a filtering device used in the production of shock absorber oil for new energy vehicles, including a first shell 10, a second shell 20, a filter column 30, and a heating unit 40. The filter column 30 is detachably fixedly connected to the center position inside the second shell 20, and the heating unit 40 is installed at the center position inside the first shell 10. The filter column 30 and the heating unit 40 are positioned relative to each other so that after the first shell 10 and the second shell 20 are connected, the filter column 30 and the heating unit 40 are matched and connected.

[0040] The design of the filter column 30 and the heating unit 40 of the present invention integrates heating and filtering in one device, which can not only solve the problem of easy solidification of shock absorber oil under low temperature conditions, but also increase the temperature of the shock absorber oil and reduce the viscosity, so that the filter column 30 can filter out solid impurities. The volatile organic compounds generated by heating in the equipment will be discharged through the exhaust gas outlet 101 and the exhaust gas pipe 50, and the exhaust gas will be recovered and processed in a unified manner to reduce the generation of secondary pollutants and protect the environment.

[0041] The oil mentioned above and below refers to the shock absorber oil, which will not be described in detail later. The specific structure design and principle are as follows:

[0042] The filter column 30 includes a flow cavity 301 which is opened in the center of the filter column 30 and is connected vertically, and is used for the outflow of the filtered shock absorber oil. The space is large and not easy to cause blockage. When cleaning later, due to the vertical connection design, cleaning parts such as brushes and cleaning heads can also enter, which is easy to clean.

[0043] Inlet ports 302 are arranged in a circular array on the outer surface of the filter column 30. The shock absorber oil enters from the outside to the inside in batches, which reduces the impact of the shock absorber oil on the filter screen, reduces the generation of bubbles, and further reduces the contact area between the oil and the air, thereby reducing the possibility of oil oxidation and achieving the oil performance is not damaged during the filtering process;

[0044] The number of the filter screens 303 is equal to the number of the inlets 302, and they are embedded in the filter column 30 between the flow cavity 301 and the inlet 302, and are used to connect the flow cavity 301 and the inlet 302. According to the composition of the shock absorber oil, filter screens with different chemical tolerances are selected, such as pure metal filter screens, alloy filter screens, and stainless steel filter screens, in order to prevent the filter screens 303 from being contaminated by the shock absorber oil, thereby filtering the shock absorber oil and causing secondary pollution;

[0045] The connecting column 304 is vertically fixed on the bottom end surface of the filter column 30 and is used to connect with the inner center of the first shell 10. Firstly, the filter column 30 is detachably fixedly connected to the inner center of the first shell 10 through the connecting column 304, which is convenient for replacement. Secondly, it is connected to the three-way valve 60 to output the filtered oil or the cleaning liquid with higher impurity content after cleaning.

[0046] In one specific embodiment, the horizontal cross-section of the inlet 302 is a parallelogram, and the angle A between the hypotenuse 321 of the inlet 302 and the horizontal line is 5-30°, which prevents the inlet 302 from being directly aligned with the liquid inlet pipe 201. The shock absorber oil cannot directly impact the filter 303, further reducing the pressure on the filter 303 and extending the service life of the filter 303.

[0047] In other embodiments, the filter column 30 further includes a connection port 305 and a plurality of heat conductive wires 306 , wherein the heat conductive wires 306 are vertically embedded in the filter column 30 between adjacent inlets 302 , and a connection port 305 for connecting to the heating unit 40 is provided at the top of the heat conductive wires 306 .

[0048] Furthermore, the thermal conductivity of the heat conducting wire 306 is higher than that of the filter column 30. Once the heat conducting wire 306 is connected to a heat source, it can quickly conduct heat from the inside out, thereby allowing the filter column 300 in contact with the inlet 302 to heat up quickly, reducing the viscosity of the oil near the filter screen 303 and facilitating filtration.

[0049] In this embodiment, the heating unit 40 includes a heating wire 401 and a controller 402; the heating wire 401 is distributed on the top end surface inside the first shell 10, and is electrically connected to the controller 402 on the top end surface outside the first shell 10, and the controller 402 is electrically connected to an external power supply;

[0050] A heat conducting plate 403 and ball bearings 404, wherein the heat conducting plate 403 contacts the heating wire 401 and is locked on the inner surface of the first shell 10, and a plurality of ball bearings 404 are embedded on one end surface of the heat conducting plate 403, wherein the number of ball bearings 404 is equal to the number of connecting ports 305, so that the ball bearings 404 cooperate with the connecting ports 305 to connect the heat conducting wire 306, and the ball bearings 404 separate from the connecting ports 305 to disconnect the heat conducting wire 306.

[0051] The present invention places the heating unit 40 on top to conduct heat to the filter column 30 from top to bottom. The split design allows the ball 404 to contact and conduct heat with the filter column 30, or the ball 404 is separated from the connecting port 305, and the heat-conducting wire 306 is not designed to conduct heat. They are independent of each other and do not interfere with each other. Later replacement of the filter column 30 will not affect the normal operation of the heating unit 40.

[0052] In one specific embodiment, a heat insulating layer 405 is provided between the heating wire 401 and the first shell 10 to isolate heat and prevent the temperature from affecting the normal operation of the controller 402. The heat insulating layer 405 includes but is not limited to materials made of rock wool, slag wool, and glass wool, as long as they can isolate heat.

[0053] In other embodiments, the second shell 20 further includes a liquid inlet pipe 201 arranged at a preset angle B on the outer surface of the second shell 20, wherein the preset angle B is 30-60°, and the preset angle B is the angle between the tangent of the outer surface of the second shell 20 and the liquid inlet pipe 201. The liquid inlet pipe 201 is not directly aligned with the inlet 302, and the shock absorber oil cannot directly impact the filter 303, further relieving the pressure of the filter 303, extending the service life of the filter 303, and slowly introducing the liquid to avoid the rapid flow of the shock absorber oil to generate a large number of bubbles.

[0054] In other embodiments, the space between the inner surface of the second shell 20 and the filter column 30 is a storage chamber 202 for shock absorber oil. When the storage chamber 202 is filled with oil, the oil is injected and flows out at the same time. The filled liquid plus the liquid slowly injected through the liquid inlet pipe 201 can quickly reduce the generation of bubbles.

[0055] In this embodiment, the present invention also includes an exhaust pipe 50. An exhaust outlet 101 is opened at the top of the first shell 10. The exhaust outlet 101 is connected to the exhaust pipe 50 to discharge volatile gases generated by the equipment. The volatile gases are collected and processed in a certain direction to reduce the generation of secondary pollutants and protect the environment.

[0056] In this embodiment, the present invention also includes a three-way valve 60, a first discharge pipe 70 and a second discharge pipe 80. The three-way valve 60 is connected to the inner center of the second shell 20 and is connected to the connecting port 305 at the bottom end of the filter column 30. The three-way valve 60 can also be directly connected to the second shell 20. The other two ends of the three-way valve 60 are respectively connected to the first discharge pipe 70 and the second discharge pipe 80. When the three-way valve 60 is started, the shock absorber oil filtered by the filter column 30 is discharged from the first discharge pipe 70 after passing through the three-way valve 60; the cleaned liquid will be discharged through the second discharge pipe 80.

[0057] In this embodiment, the present invention also includes a number of sealing rings for sealing the connection between the first shell 10 and the second shell 20, for sealing the connection between the filter column 30 and the second shell 20, etc., to prevent the outflow of shock absorber oil and play a sealing role.

[0058] A method for using the above-mentioned filtering device comprises the following steps:

[0059] Step S1, assemble the device, and start the heating unit 40 of the device through the controller 402 to preheat the filter column 30 for 1-5 minutes;

[0060] Step S2, start the three-way valve 60, inject shock absorber oil into the accommodating chamber 202 of the equipment through the liquid inlet pipe 201, and the shock absorber oil filtered by the filter column 30 is discharged from the first discharge pipe 70 after passing through the three-way valve 60;

[0061] Step S3, if the volatile organic compounds generated by heating in the equipment are discharged through the exhaust gas outlet 101 and the exhaust gas pipe 50, the exhaust gas is uniformly recovered and processed;

[0062] Step S4, if the filter column 30 of the equipment is blocked, the filter column 30 can be disassembled, the three-way valve 60 is started, and the cleaning liquid or new shock absorber oil is re-injected. The cleaned liquid will be discharged through the second discharge pipe 80, and then, a new filter column 30 is reassembled and steps S1 and S2 are repeated.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
