Description

Technical Field

[0001] The invention relates to the technical field of engine crankcase oil-gas separation devices, in particular to an electromagnetic adsorption type oil-gas separator. Background Art

[0002] Crankcase blowby refers to the phenomenon that part of the unburned combustible mixture and combustion products will enter the crankcase through the gap between the piston ring and the cylinder wall during the operation of the engine. When the engine is running at low temperatures, liquid fuel may also seep into the crankcase. Crankcase blowby is an inevitable phenomenon when the engine is running.

[0003] As motor vehicle pollutant emission standards become increasingly stringent, considering that the gas entering the crankcase contains more pollutants, such as oil particles, incompletely burned fuel components, moisture, etc., these gases cannot be discharged directly into the atmosphere. In the prior art, oil-gas separators are usually used to purify these gases before they are discharged. Faced with increasingly stringent motor vehicle pollutant emission standards, higher requirements are placed on the purification efficiency of oil-gas separators, and traditional oil-gas separators are increasingly difficult to meet environmental protection standards.

[0004] In order to solve the above problems, a Chinese patent (authorization announcement number: CN 108457719 B) discloses an oil-gas separator, which includes: a first shell, having an oil-gas inlet and a first channel and a second channel separated from each other; a first separator, connected to the first channel; a second separator, connected to the second channel; a control valve assembly, arranged in the first shell, and the oil-gas inlet can be selectively connected to the first channel and / or the second channel through the control valve assembly; wherein the first separator and / or the second separator has a spiral separation structure. The oil and gas are separated by centrifugal action to achieve oil-gas separation and improve the separation effect of oil-gas separation. Therefore, the oil-gas separator provided by the invention can solve the technical problem of low separation efficiency of the oil-gas separator in the prior art.

[0005] However, this invention is mainly aimed at the separation of large particles of oil, gas and solids; for fine solid or liquid particles, it is difficult to meet environmental protection standards because they cannot be effectively separated by centrifugal force. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide an electromagnetic adsorption type oil-gas separator in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: to provide an electromagnetic adsorption type oil-gas separator, comprising: an outer shell, in which a channel for the oil-gas mixture to pass through is constructed; A discharge member connected to the outer shell, the discharge member having a conductive pin located in the channel, and the discharge member energizes the conductive pin to stimulate negative charges to encapsulate liquid particles in the oil-gas mixture; A conductive baffle is connected to the outer shell and arranged opposite to the conductive pins. The conductive baffle abuts against the engine cylinder to absorb liquid particles wrapped by negative charges.

[0008] In the above-mentioned electromagnetic adsorption oil-gas separator, the discharge component includes a DC amplifier and a charge release device electrically connected to the DC amplifier, the DC amplifier is fixed on the outer shell and electrically connected to the vehicle power supply, and the charge release device is electrically connected to the conductive pin.

[0009] In the above-mentioned electromagnetic adsorption type oil-gas separator, a plurality of grooves are formed on a side of the conductive baffle facing the conductive pin.

[0010] In the above-mentioned electromagnetic adsorption oil-gas separator, an air inlet chamber, a first separation plate, an exhaust chamber and a storage chamber are constructed in the outer shell, the air inlet chamber is used to introduce the oil-gas mixture, the air inlet chamber, the first separation plate and the exhaust chamber are arranged along the moving direction of the oil-gas mixture, the air inlet chamber has an exhaust port facing the first separation plate, the oil-gas mixture discharged from the exhaust port can be initially separated due to impact on the first separation plate, the exhaust chamber is used to discharge the separated gas, and the storage chamber is used to store the separated liquid particles.

[0011] The above-mentioned electromagnetic adsorption type oil-gas separator also includes a second separation plate, which is arranged opposite to the first separation plate, and the conductive pin and the conductive baffle are located between the first separation plate and the second separation plate, for extending the channel.

[0012] In the above-mentioned electromagnetic adsorption type oil-gas separator, the first separation plate and the second separation plate are both formed by extending outward from the inner side wall of the outer shell.

[0013] In the above-mentioned electromagnetic adsorption type oil-gas separator, the receiving chamber is configured with a liquid discharge port, and the liquid discharge port is connected to a one-way valve for allowing the separated liquid to be discharged from the exhaust chamber.

[0014] In the above-mentioned electromagnetic adsorption type oil-gas separator, a sealing groove is constructed on the outer shell, and the sealing groove is connected to a sealing ring.

DETAILED DESCRIPTION

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figures 1 to 5 As shown, an electromagnetic adsorption type oil-gas separator of the present invention comprises: an outer shell 100 , a discharge motor and a conductive baffle 300 .

[0020] Among them, a channel 110 for the oil-gas mixture to pass through is constructed in the outer shell 100; the discharge component 200 is connected to the outer shell 100, and the discharge component 200 has a conductive pin 210 located in the channel 110. After the discharge component 200 energizes the conductive pin 210, negative charges are stimulated to wrap liquid particles in the oil-gas mixture; the conductive baffle 300 is connected in the outer shell 100 and is arranged opposite to the conductive pin 210. The conductive baffle 300 abuts against the engine cylinder body to absorb liquid particles wrapped by the negative charge.

[0021] The installation position of the oil-gas separator in this scheme is as follows Figure 1 As shown, the lower end of the oil-gas separator is connected to the cylinder block of the automobile engine, and the conductive baffle 300 in the oil-gas separator is in contact with the engine cylinder block. During operation, the channel 110 in the outer shell 100 is filled with an oil-gas mixture. When the oil-gas mixture passes through the conductive pin 210, the discharge member 200 applies a high-voltage direct current to the conductive pin 210, causing the end of the conductive pin 210 to release a negative charge. When these negative charges come into contact with the liquid particles in the oil-gas mixture, they wrap them. The conductive baffle 300 is in contact with the engine cylinder block, which is equivalent to the grounding effect relative to the negative charge released by the conductive pin 210, so that the conductive baffle 300 can absorb the liquid particles wrapped by the negative charge and capture the liquid particles with smaller diameters in the oil-gas mixture, ultimately improving the separation effect of the oil-gas separator and meeting environmental protection standards.

[0022] In this solution, the discharge component 200 includes a DC amplifier 220 and a charge release device electrically connected to the DC amplifier 220 . The DC amplifier 220 is fixed on the outer shell 100 and electrically connected to the vehicle power supply. The charge release device is electrically connected to the conductive pin 210 .

[0023] The DC amplifier 220 can amplify the voltage signal of the vehicle power supply electrically connected thereto. Common designs of the DC amplifier 220 include direct coupling amplifiers, differential amplifiers, etc. Then, the charge release device in the oil-gas mixture releases negative charges through the conductive pin 210 to wrap the liquid particles in the oil-gas mixture.

[0024] like Figure 4 As shown, a plurality of grooves 211 are formed on one side of the conductive baffle 300 facing the conductive pin 210 .

[0025] The groove 211 is used to increase the contact area between the conductive baffle 300 and the conductive pin 210, so that the conductive baffle 300 can absorb more liquid particles, and can also reduce the weight of the conductive baffle 300 to reduce the manufacturing cost of the entire oil-gas separator.

[0026] An air inlet chamber 120, a first separation plate 130, an exhaust chamber 140 and a storage chamber 150 are constructed in the outer shell 100. The air inlet chamber 120 is used to introduce the oil-gas mixture. The air inlet chamber 120, the first separation plate 130 and the exhaust chamber 140 are arranged along the moving direction of the oil-gas mixture. The air inlet chamber 120 has an exhaust port 121 facing the first separation plate 130. The oil-gas mixture discharged from the exhaust port 121 can be initially separated due to impact on the first separation plate 130, and liquid particles with larger diameters are first separated from the oil-gas mixture. The exhaust chamber 140 is used to export the separated gas, and the storage chamber 150 is used to store the separated liquid particles.

[0027] Furthermore, the present solution also includes a second separation plate 400, which is arranged opposite to the first separation plate 130, and the conductive pin 210 and the conductive baffle 300 are located between the first separation plate 130 and the second separation plate 400, for extending the channel 110 and increasing the separation efficiency of the oil-gas separator.

[0028] During operation, liquid particles with larger diameters in the oil-gas mixture are separated from the gas in the oil-gas mixture after hitting the first separation plate 130 and the second separation plate 400 in sequence, and finally collected in the receiving chamber 150. Liquid particles with smaller diameters are also separated from the oil-gas mixture under the action of the conductive pins 210 and the conductive baffle 300, and finally the remaining gas is discharged from the outer shell 100 after passing through the exhaust chamber 140.

[0029] Preferably, the first separation plate 130 and the second separation plate 400 are both formed by extending outward from the inner side wall of the outer shell 100 .

[0030] like Figure 4 and Figure 5 As shown, the receiving chamber 150 is configured with a liquid discharge port 151 , and a one-way valve 160 is connected to the liquid discharge port 151 to allow the separated liquid to be discharged from the exhaust chamber 140 .

[0031] After the liquid in the storage chamber 150 is stored to a certain extent, the one-way valve 160 opens to allow the liquid to be discharged from the storage chamber 150 .

[0032] like Figure 4 and Figure 5 As shown, a sealing groove 170 is configured on the outer shell 100 , and a sealing ring 180 is connected to the sealing groove 170 to prevent the unseparated oil-gas mixture from being discharged from the channel 110 in advance.
