Description

Technical Field

[0001] The invention relates to the technical field of fuel product collection equipment, and in particular to a diesel combustion product deposition film collection equipment and method. Background Art

[0002] The main combustion products of diesel are sulfur oxides (SO x ), nitrogen oxides (NO x ), carbon oxides (CO x ), hydrocarbons (HC), ash, etc., among which SO X Harmful substances such as sulfur and sulfur dioxide will cause harm to the environment. In recent years, strict restrictions have been imposed on the emission standards of diesel combustion products, which has brought new challenges to diesel manufacturers. They must ensure the combustion effect of diesel and the power of the entire diesel engine, as well as environmental protection. In the use of existing diesel engines, in order to limit the sulfur content in diesel, when using diesel with a lower sulfur content, the exhaust valve has severe wear. This is because the sulfur content in the combustion product deposition film on the cone surface of the exhaust valve is low, which reduces lubricity and aggravates wear, thereby reducing the service life of the diesel engine. In order to better balance the service life of diesel engine parts and environmental protection, analyzing the composition of diesel combustion products to design a better-proportioned diesel is the primary task before the production of fuel engines.

[0003] The method for collecting fuel products is usually to collect the combustion products and then send them to a material surface detection device such as a SEM scanning electron microscope. In the prior art, after the combustion products are collected, usually only a thin layer is covered on the detection sheet. The SEM scanning electron microscope has requirements on the size of the sample when used for detection. Therefore, the detection sheet needs to be cut before being sent to the electron microscope. However, since the deposited film of the diesel combustion product is too thin and the bonding force between it and the collection plate is not strong, it is easily damaged during the cutting process.

[0004] In view of the above problems, a diesel combustion product deposit film collection device and method are proposed. Summary of the invention

Therefore, the test piece needs to be cut before being sent into the electron microscope. However, since the deposited film of the diesel combustion product is too thin and the bonding force between it and the collection plate is not strong, it is easily destroyed during the cutting process.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] refer to Figures 1 to 9 , a diesel combustion product deposition film collection device, comprising an n-type support plate 1, an expansion mounting plate 2, a lower barrel 3, an upper barrel 4, a diesel tank 5, a collection plate 21, an annular condenser 18, an igniter 24, a liquid storage barrel 9, a driving mechanism, an injection mechanism, a sliding mechanism, and an exhaust purification mechanism; The lower end of the horizontal plate of the n-shaped support plate 1 is equipped with an upper barrel body 4, and the lower end of the upper barrel body 4 is detachably equipped with a lower barrel body 3. The upper barrel body 4 and the lower barrel body 3 are disassembled by screws. The screws only fix the upper barrel body 4 and the lower barrel body 3, but do not seal them. The purpose is to provide circulating air in the barrel body to allow the igniter to burn under the suction of the vacuum pump 1001 described later. The upper end of the bottom wall of the lower barrel body 3 is equipped with an igniter 24, which is used to ignite the diesel sprayed by the fuel injection mechanism described later; An annular condenser 18 is installed on the inner wall of the upper barrel 4, and water pipes are installed at both ends of the annular condenser 18. The two water pipes penetrate the two side walls of the upper barrel 4 and are detachably connected to the external water pump. The annular condenser 18 is used to cool the combustion gas, so that the combustion products are cooled and precipitated and collected by the collection tray described later; The lower end of the annular condenser tube 18 is detachably contacted with a plurality of collecting trays 21, which are driven to slide by a sliding mechanism, and are used to collect the combustion products; A driving mechanism is installed in the middle of the upper end of the horizontal plate of the n-shaped support plate 1, and the sliding mechanism is driven by the driving mechanism; A diesel tank 5 is installed on the outer side of the left side wall of the lower barrel 3. A fuel injection mechanism is installed on the upper end of the diesel tank 5. The fuel injection mechanism is driven by the driving mechanism to work. The diesel tank 5 is used to store diesel to be burned. The diesel inside the diesel tank 5 will be driven by the fuel injection mechanism to be injected into the lower barrel 3 and ignited by the igniter 24 located in the lower barrel 3. The diesel will enter the lower barrel 3 in the form of mist under the action of the fuel injection mechanism, which not only avoids diesel leakage but also fully increases the contact area between the diesel and the igniter flame, so that the diesel burns more fully. An expansion mounting plate 2 is vertically mounted on the inner side wall of the right vertical plate of the n-type support plate 1, a liquid storage barrel 9 is mounted on the upper end of the expansion mounting plate 2, and a purification exhaust mechanism is mounted on the upper end of the liquid storage barrel 9. The purification exhaust mechanism is driven by the driving mechanism to neutralize the exhaust gas after combustion through the liquid storage barrel 9 and discharge it to the outside, thereby achieving the effect of reducing pollution.

[0023] The sliding mechanism comprises a cam 13, a sliding rod 14, and a first return spring 1402; A first mounting plate 101 is vertically mounted at the middle of the upper end of the horizontal plate of the n-shaped support plate 1, and a cam 13 is movably mounted on the rear side wall of the first mounting plate 101. The cam 13 is rotatably mounted on the rear side wall of the first mounting plate 101 via a first rotating shaft; A rectangular block 1401 is movably mounted on the lower end of the cam 13, a first end of a slide bar 14 is mounted on the lower end of the rectangular block 1401, and a round table 20 is mounted on the second end of the slide bar 14 which slides through the horizontal plate of the n-shaped support plate 1; The second end of the slide bar 14 is fixedly connected to the upper end of the small cross section of the truncated table 20, and a plurality of collecting trays 21 are detachably arranged at the lower end of the large cross section of the truncated table 20 through a fastening mechanism; A first return spring 1402 is installed on the outer wall of the slide bar 14 located above the horizontal plate of the n-type support plate 1. The upper and lower ends of the first return spring 1402 are fixedly connected to the lower end of the rectangular block 1401 and the upper end of the n-type support plate 1 respectively; The inner ring wall of the annular condenser tube 18 is an inclined wall 1801 that cooperates with the side wall of the truncated cone 20, and the inclined wall 1801 and the side wall of the truncated cone 20 are in detachable contact. The first rotating shaft is driven to rotate by the driving mechanism. The first rotating shaft starts to rotate under the drive of the driving mechanism, and drives the cam 13 installed coaxially therewith at the same time. The cam 13 starts to rotate and periodically pushes the rectangular block 1401. Under the periodic push, the rectangular block 1401 transmits the driving force to the sliding rod 14 fixedly connected thereto, so that the sliding rod 14 can slide up and down periodically. In the process of sliding up and down, the sliding rod 14 drives the round table 20 to start sliding up and down. In the process of sliding up and down, the round table 20 drives several collecting plates 21 to start collecting the annular condenser tube 18. The lower end is regularly impacted. Since the high-temperature gas will solidify and precipitate the combustion products in the process of passing through the annular condenser 18, the combustion products can be compacted through continuous impact, and the combustion products can form a film of a certain thickness on the surface of the collecting plate 21. The inclined wall 1801 and the side wall of the cone 20 will also reciprocate in contact during this movement, thereby squeezing the combustion products. The combustion products on the side wall of the cone 20 will fall off onto the collecting plate 21 after being squeezed, and the reciprocating impact of the collecting plate 21 on the annular condenser 18 enables it to collect more combustion products within a certain period of time.

[0024] The fastening mechanism comprises a fixing plate 22 and a fastening screw 23; A fixing plate 22 is movably mounted on the lower end of the large cross section of the truncated table 20, and the fixing plate 22 is in detachable contact with the lower end of the large cross section of the truncated table 20; A plurality of collecting plates 21 are detachably disposed between the large cross-section of the truncated table 20 and the fixed plate 22; The fixing plate 22 is provided with a plurality of first screw holes at equal intervals, and the collecting plate 21 is provided with second screw holes that cooperate with the first screw holes; The first screw hole and the second screw hole are internally threadedly connected with a same fastening screw 23; The plurality of collecting plates 21 are all fan-shaped pieces, and the radius of the plurality of fan-shaped pieces is smaller than the radius of the upper barrel body 4. The fixed plate 22 can slide under the truncated table 20, so that a gap is formed between the fixed plate 22 and the bottom of the truncated table 20, and the plurality of fan-shaped collecting plates 21 can be stuck in this gap and the gap can be narrowed by tightening the screws 23, thereby achieving the fixing effect of the plurality of collecting plates 21.

[0025] The driving mechanism comprises a driving motor 29, a first bevel gear 28, and a second bevel gear 27; A driving motor 29 is installed on the outer side of the front wall of the first mounting plate 101, and the driving motor 29 is fixedly arranged on the upper end of the horizontal plate of the n-shaped supporting plate 1; A first bevel gear 28 is mounted on a fixed sleeve on the output shaft of the driving motor 29, and a second bevel gear 27 is meshedly mounted on the upper end of the first bevel gear 28; The other end of the first rotating shaft rotates through the first mounting plate 101 and is fixedly connected to the second bevel gear 27; The first rotating shaft drives the injection mechanism and the purification exhaust mechanism to work respectively by rotating. By starting the driving motor 29, the output shaft of the first motor 29 drives the first bevel gear 28 to start rotating. The first bevel gear 28 drives the second bevel gear 27 meshing therewith by rotating. The second bevel gear 27 drives the first rotating shaft coaxial therewith to start rotating by rotating.

[0026] The oil injection mechanism comprises a first sprocket 26, a second sprocket 7, a second mounting plate 102, a disc 31, a connecting rod 15, and a piston rod 16; A second mounting plate 102 is mounted on the left side of the first mounting plate 101, and the second mounting plate 102 is fixed above the horizontal plate of the n-type support plate 1; The first rotating shaft has a fixed sleeve mounted with a first sprocket 26, which is disposed between the first mounting plate 101 and the second bevel gear 27; A second sprocket 7 is rotatably mounted on the front wall of the second mounting plate 102 via a second rotating shaft, and the first sprocket 26 is sleeved and meshed with the same first chain on the outer side of the second sprocket 7; The other end of the second rotating shaft rotates through the second mounting plate 102 to be fixedly mounted with a disc 31, and the first end of the connecting rod 15 is rotatably mounted at an eccentric position on the rear wall of the disc 31; The second end of the connecting rod 15 is rotatably mounted with the first end of the piston rod 16; The outer sleeve of the piston rod 16 is provided with a first air guide tube 6, and the first air guide tube 6 is arranged through the horizontal plate of the n-shaped support plate 1; A piston disc 1601 is mounted on the second end of the piston rod 16, and the piston disc 1601 is slidably disposed on the inner wall of the first air guide pipe 6; The lower end of the first air guide pipe 6 is connected to a reserve oil storage tank 601, and the lower end of the reserve oil storage tank 601 is connected to the top wall of the diesel tank 5 through the first oil guide pipe 501; The right side wall of the reserve oil storage tank 601 is connected to the left side wall of the upper barrel 4 through a second oil guide pipe, an atomizing nozzle is installed at the end of the second oil guide pipe located in the upper barrel 4, and a first one-way valve is installed at the end of the second oil guide pipe located in the reserve oil storage tank 601; An air inlet is provided on the left side wall of the reserve oil storage tank 601. An air filter element and a second one-way valve are detachably installed in the air inlet. The first one-way valve and the second one-way valve are installed in opposite directions. When the first one-way valve is opened, the second one-way valve is closed. The diesel tank 5 is provided with an oil suction mechanism, and the piston plate 601 drives the oil suction mechanism to work by movement. The first rotating shaft also drives the first sprocket 26 coaxially installed therewith during the rotation process. The first sprocket 26 transmits the rotation driving force to the second sprocket 7 through the first chain, so that the second sprocket 7 starts to rotate. The second sprocket 7 drives the disc 31 coaxially installed therewith through the rotation, so that the disc 31 starts to rotate. During the rotation process, the disc 31 drives the connecting rod 15 to start reciprocating deflection. The connecting rod 15 drives the connecting rod 15 to rotate with the reciprocating deflection. The dynamically connected piston rod 16 begins to slide up and down periodically in the first air duct 6, and the piston disc 1601 fixedly installed at the lower end of the piston rod 16 also begins to slide up and down to suck the reserve oil storage tank 601. When the piston disc 1601 slides downward, the diesel pumped up in the reserve oil storage tank 601 will pass through the first one-way valve and the high-pressure nozzle into the lower barrel 3 and be ignited.

[0027] The oil suction mechanism comprises a ball 19, a movable rod 1901, a fixed rod 1902, and a second return spring 25; A ball 19 is movably installed in the first oil guide pipe 501, and the ball 19 is in detachable contact with the first oil guide pipe 501; The first end of the movable rod 1901 is fixedly mounted on the lower end of the ball 19, and a bump is mounted on the second end of the movable rod 1901; A fixed rod 1902 is vertically fixedly installed on the upper end of the bottom wall of the diesel tank 5, and a movable rod 1901 is slidably sleeved on the outer side wall of the fixed rod 1902; The lower end of the protrusion is connected to the upper end of the bottom wall of the diesel tank 5 through the second return spring 25. When the piston disc 1601 slides upward, the first one-way valve is closed, and the second one-way valve is opened. The ball in the first oil guide pipe 501 begins to slide upward under the negative pressure and drives the movable rod 1901 to begin to slide upward. At this time, the ball 19 is separated from the first oil guide pipe 501, and a connecting space is formed between the diesel tank 5 and the reserve oil storage pipe 601. The diesel tank 5 has a certain flexibility. When it receives the negative pressure, it begins to compress and squeeze the diesel inside into the reserve oil storage pipe. 601, and at the same time, external air will also enter the reserve oil storage pipe 601 through the second one-way valve. When the piston disc 1601 starts to slide downward, the second one-way valve closes and the first one-way valve opens. The ball 19 drives the movable rod 1901 to start falling off and block the first oil guide pipe 501. At this time, the fixed rod 1902 plays the role of fixing the movable track of the movable rod 1901 to ensure that it will not deviate from the first oil guide pipe 501 during the up and down sliding process. The oil and air in the reserve oil storage tank 601 will be sprayed into the barrel body through the first one-way valve.

[0028] The purification exhaust mechanism comprises an exhaust fan 12, an exhaust gas box 8, an air intake pipe 17, a third sprocket 30, and a fourth sprocket 11; The third sprocket 30 is installed on the fixed sleeve of the first rotating shaft, and the third sprocket 30 is arranged between the first mounting plate 101 and the cam 13; An exhaust box 8 is installed on the right side of the first mounting plate 101, and the exhaust box 8 is fixedly arranged on the upper end of the horizontal plate of the n-shaped support plate 1; A fourth sprocket 11 is rotatably mounted on the front wall of the exhaust box 8 via a third rotating shaft, and the third sprocket 12 is sleeved and meshed with the same second chain on the outer side of the fourth sprocket 11; The other end of the third rotating shaft rotates through the front wall of the exhaust box 8 to install an exhaust fan 12, which is arranged in the exhaust box 8; An exhaust pipe is installed at the bottom end of the exhaust box 8, and a first end of the exhaust pipe penetrates the horizontal plate of the n-shaped support plate 1 and is connected to the bottom wall of the exhaust box 8; The second end of the exhaust pipe is connected to an exhaust pipe 10, and the exhaust pipe 10 is connected to the liquid storage tank 9 through a second air guide pipe; An air pump 1001 is installed in the exhaust pipe 10, and the input end and the output end of the air pump 1001 are respectively connected to the first end of the air intake pipe 17; The output end of one of the air intake pipes 17 passes through the second air guide pipe and is connected to the liquid storage tank 9; The input end of another air intake pipe 17 is connected to the right side wall of the upper barrel 4; The air intake pipe 17 located in the upper barrel body 4 is arranged above the annular condenser 18. During the rotation of the first rotating shaft, it also drives the third sprocket 30 installed coaxially therewith. During the rotation of the third sprocket 30, the rotation driving force is transmitted to the fourth sprocket 11 through the second chain, so that the fourth sprocket 11 starts to rotate. During the rotation of the fourth sprocket 11, it drives the exhaust fan 12 installed coaxially therewith. The combustion gas located in the upper and lower barrel bodies will pass through the gap between the disc 20, the collecting disc 21 and the annular condenser 18 to enter the top of the annular condenser 18. An air storage chamber is formed between the upper end of the annular condenser 18 and the upper barrel body 4. The exhaust gas located in the air storage chamber will enter the liquid storage tank 9 through the two air intake pipes 17 under the suction force of the vacuum pump 1001, and then be sucked into the exhaust box 8 by the rotating exhaust fan. The side wall of the exhaust box 8 can be installed with a filter to further filter the exhaust gas, and it is discharged to the outside of the equipment through the filter.

[0029] The liquid storage tank 9 contains an alkaline solution, and the second end of the air intake pipe 17 in the liquid storage tank 9 is located below the liquid surface of the alkaline solution, so as to neutralize the acidic ions in the exhaust gas, reduce the pollution and discharge it to the outside.

[0030] The diesel combustion product deposition film collection method comprises the following steps: Step 1 (S1): Ignite the igniter 24 and start the water pump to fill the annular condenser tube 18 with condensate, which serves to increase the temperature inside the upper and lower barrels and circulate the condensate inside the condenser tube 18; Step 2 (S2): Remove the first one-way valve and the second one-way valve, start the drive motor 29 and reduce the speed, so that the reserve oil storage pipe 601 is connected with the external air pressure, so that the piston plate 1601 will not stimulate the ball 19 to slide up and down during the up and down sliding process, and the purpose is to enable the collection plate 21 to impact up and down at a slower speed. At this time, the motor speed is preferably 100-200r / min, so that the collection plate 21 can adapt to the impact movement. This process needs to be maintained for 10-20 minutes; Step 3 (S3): After the temperature stabilizes (20) minutes later, install the first check valve and the second check valve, increase the speed of the drive motor 29, and turn on the vacuum pump 1001, which is used to form a negative pressure environment in the reserve oil storage pipe 601, so that the piston plate 1601 can stimulate the ball to slide up and down during the up and down movement, so that the diesel and filtered air can enter the reserve oil storage pipe 601. At this time, the motor speed is preferably 800-1000r / min, so that the impact movement is faster, and the diesel will also be sprayed out through the nozzle and ignited by the igniter; Step 4 (S4): After waiting for more than 12 hours, turn off the igniter 24 and the drive motor 29, and turn off the water pump and the vacuum pump 1001 to ensure that the combustion products collected on the collection plate 21 accumulate to a certain thickness and are continuously compacted within 12 hours, and finally form a deposited film that can be detected; Step 5 (S5): After the temperature of the equipment is lowered to room temperature, the lower barrel 3 is removed, and the fastening screws 23 at the lower end of the fixing plate are removed, and the collecting plate 21 is taken out. Since the collecting plate 21 is fan-shaped and is composed of a plurality of fan-shaped collecting plates 21 to form a circular plate, any number of fan-shaped collecting plates 21 can be removed at will for testing; Step six (S6): Place the collection plate 21 with the deposited film of diesel combustion products in an oven for 24 hours, take out the material and start testing. Its function is to evaporate the liquid substances in the combustion products to make the combustion products purer.

[0031] Implementation method of the present invention: Place the device on a horizontal surface, put the diesel to be burned into the diesel tank 5, and flush the alkaline solution into the liquid storage tank; Ignite the igniter 24 and start the water pump to fill the annular condenser tube 18 with condensate; Remove the first check valve and the second check valve, start the drive motor 29 and reduce the speed, so that the reserve oil storage pipe 601 is connected with the external air pressure. The motor speed is preferably 100-200 r / min at this time, so that the collection plate 21 can adapt to the impact movement. This process needs to be maintained for 10-20 minutes; After 20 minutes, the first one-way valve and the second one-way valve are installed, the speed of the driving motor 29 is increased, and the vacuum pump 1001 is turned on. The piston plate 1601 starts to stimulate the ball 19 to slide up and down during the up and down movement, so that the diesel enters the reserve oil storage pipe 601. At this time, the motor speed is preferably 800-1000r / min, so that the impact movement is faster. At this time, the diesel will also be sprayed out through the nozzle and ignited by the igniter. A part of the ignited gas passes through the annular condenser 18 and forms a deposition film on the collection plate 21 under the impact of the collection plate 21. The other part of the exhaust gas is neutralized by the alkaline solution in the liquid storage tank 9 and discharged by the exhaust fan 12; After 12 hours, turn off the igniter 24 and the drive motor 29, and turn off the water pump and the vacuum pump 1001 to ensure that the combustion products collected on the collection plate 21 accumulate to a certain thickness and are continuously compacted within 12 hours, and finally form a deposited film that can be detected; When the temperature of the equipment drops to room temperature, remove the lower barrel 3, remove the fastening screws 23 at the lower end of the fixing plate 22, and take out the collecting plate 21 to be used; The collected tray 21 is placed in an oven for drying for 24 hours, and the material is taken out to start testing.

[0032] The driving mechanism of the present invention can drive the injection mechanism and the sliding mechanism at the same time, reducing the use of the driving source. The sliding mechanism of the present invention can drive a plurality of collecting plates to form an impact deformation below the annular condenser tube, and further compact the collected combustion products through impact to avoid dispersion. The present invention uses a plurality of fan-shaped collecting plates to collect the combustion products, which is convenient for sending them to the SEM scanning electron microscope for direct detection, avoiding cutting the collecting plates. The purification exhaust mechanism of the present invention can discharge the neutralized exhaust gas faster, avoiding the phenomenon of excessive temperature caused by gas accumulation.
