Description

Technical Field

[0001] The invention relates to the technical field of engine cylinder heads, and in particular to spray washing equipment and a process for an engine cylinder head. Background Art

[0002] The engine cylinder head is located at the top of the engine. It seals the cylinder and forms a combustion chamber together with the cylinder body. It has a complex shape and usually has multiple holes for installing spark plugs (gasoline engines) or fuel injectors (diesel engines), as well as intake and exhaust ducts. These channels are used to guide the mixture of air and fuel into the combustion chamber and to discharge the exhaust gas after combustion. The engine cylinder head is usually made of aluminum alloy. This is because aluminum alloy has the advantage of light weight, which can reduce the overall weight of the engine and is beneficial to the fuel economy and handling performance of the vehicle. At the same time, aluminum alloy has good thermal conductivity and can effectively dissipate the heat generated by combustion to avoid local overheating of the engine. However, the cylinder heads of some high-performance or heavy-loaded engines may also be made of cast iron. Cast iron cylinder heads have high strength and better high temperature resistance, but are heavier.

[0003] When the engine cylinder head is sprayed and flushed, a large amount of water flow will be generated due to various oil stains and impurities attached to the surface of the cylinder head. If it is directly discharged, a large amount of water resources will be wasted. Summary of the invention

For some cylinder heads with complex shapes, multiple nozzles are required to spray from different angles, and fixed multi-angle nozzles can be used to achieve spraying at different angles to ensure that the grooves, channels and other parts of the cylinder head can be rinsed by the cleaning liquid;

[0009] Preferably, the filter mechanism comprises a filter tube, the top of the filter tube is fixedly connected to the water outlet end of the water pump, the top of the filter tube is fixedly connected to the first one-way valve, the side of the filter tube is fixedly connected to the inner side of the fixing seat and the bottom of the inner cavity of the storage shell, one end of the filter tube away from the first one-way valve is fixedly connected to the second one-way valve, the end of the filter tube away from the storage shell is fixedly connected to the inner side of the connecting hole, the side of the inner wall of the filter tube close to the second one-way valve is fixedly connected to a filter plate, the side of the filter plate away from the second one-way valve is slidably connected to a sliding rod, the other end of the sliding rod is fixedly connected to a bracket, the side of the bracket close to the filter plate is fixedly connected to an ejection assembly, the ejection assembly is concentrically arranged with the mesh of the filter plate, and a third elastic sleeve is provided on the sliding rod. Spring, one end of the third spring is fixedly connected to the bracket, and the other end of the third spring is fixedly connected to the filter plate; by turning on the water pump, the extraction work of the water pump is performed, so that the first one-way valve and the second one-way valve are opened, so that the water pump extracts the water flow in the recovery shell, and at the same time, the water flow entering the filter tube is filtered through the filter plate, thereby preventing impurities mixed in the water flow from entering the filter tube, and at the same time, through the extraction force of the water pump, the water flow enters the storage shell through the filter tube, and at the same time, when the water flow passes through the filter tube, the impact force of the water flow can cause the bracket to drive the ejection component to move to the side away from the filter plate through the sliding rod, thereby preventing the ejection component from being blocked at the mesh of the filter plate, causing the water flow speed to decrease;

[0010] Preferably, the ejection assembly includes an ejection rod, one end of the ejection rod is fixedly connected to the side surface of the bracket, the side surface of the ejection rod is provided with a notch, the inner side of the notch is slidably connected with a sliding block, the side surface of the sliding block is fixedly connected with a round rod, the end of the round rod away from the sliding block is fixedly connected with an ejector pin, both sides of the ejector pin are fixedly connected with a scraper, a fourth spring is sleeved on the round rod, one end of the fourth spring is fixedly connected to the end of the ejection rod away from the bracket, and the other end of the fourth spring is fixedly connected to the side surface of the scraper; when the extraction work of the water pump is finished, the water pump stops working, and the bracket is driven to move toward the filter plate by the third spring reset, so that the bracket drives the ejector pin to eject impurities blocked in the mesh of the filter plate through the ejection rod, thereby preventing the filter plate from being blocked by impurities mixed in the water flow when the filter plate is filtering for a long time, and at the same time, the bracket is continuously reset and pulled by the third spring, so that the bracket drives the ejection rod to continuously move at the mesh of the filter plate The scraper moves in a row, so that the scraper can clean the inner wall of the filter plate mesh, thereby preventing the sludge impurities mixed in the water flow from remaining in the mesh of the filter plate, thereby causing the filter plate mesh to be blocked. When the scraper contacts the inner wall of the filter plate mesh for cleaning, the extrusion force between the scraper and the impurities on the inner wall of the mesh is greater than the tensile force of the fourth spring, so that the round rod drives the scraper to slide in the notch through the slider, and at the same time, through the buffering work of the second spring, it is avoided that the extrusion force between the scraper and the impurities is too large, which will cause the extrusion wear of the inner wall of the filter plate mesh, and then the inner diameter of the filter plate mesh is enlarged, thereby reducing the service life of the filter plate. By symmetrically arranging the scraper on the round rod, when the water flows through the filter tube, the ejector rod is driven to separate from the filter plate mesh, and the scraper can be used to perform the first cleaning work on the filter plate mesh, thereby preventing the inner wall of the filter plate mesh from remaining dry sludge, thereby causing the water flow to slow down when the water flows through the filter plate;

The water flow in the connecting pipe is drawn into the connecting pipe, and the water flows in the connecting pipe, so that the cross drives the scraper to move on the guide rod. At the same time, by pulling the fifth spring, when the spraying and flushing work is completed and the extraction pump stops extracting, the cross is reset on the guide rod through the stretching and resetting of the fifth spring, so that the cross drives the contact plate to clean the inner wall of the connecting pipe. During the flushing process, a small amount of dirt washed off the surface of the engine cylinder head may remain on the inner wall of the connecting pipe with a mixed water flow, such as sludge impurities in the oil on the surface of the engine cylinder head. When the water flows through the connecting pipe, due to factors such as gravity and flow rate changes, it will adhere to the pipe wall. These precipitations will gradually accumulate, making the inner diameter of the connecting pipe smaller, affecting the flow rate and pressure of the water flow, thereby causing the spraying effect to deteriorate and failing to effectively flush the engine cylinder head.

[0014] Preferably, the collecting mechanism comprises a rotating rod, the bottom of the rotating rod is rotatably connected to the bottom of the inner cavity of the feeding shell, the top of the rotating rod is fixedly connected to the output end of the bottom of the dual-axis motor, the side of the rotating rod is fixedly connected to a connecting rod, the number of the connecting rods is three, and the three connecting rods are evenly arranged with the rotating rod as the center, the connecting rod is fixedly connected to the collecting shell at one end away from the rotating rod, and the side of the collecting shell is evenly provided with a circular hole, and arc plates are fixedly connected to the two sides of the inner wall of the collecting shell, the inner side of the collecting shell is slidably connected to a sliding rod, the other end of the sliding rod is fixedly connected to a semicircular plate, the side of the semicircular plate contacts the inner side of the collecting shell, the middle part of the sliding rod is fixedly connected to a baffle, the sliding rod is sleeved with a second spring, one end of the second spring is fixedly connected to the inner side of the collecting shell, and the other end of the second spring is fixedly connected to the side of the baffle; the water flow after mixing the medicine enters the recovery shell through the connecting shell In the shell, the output end at the bottom of the dual-axis motor drives the rotating rod to rotate in the inner cavity of the recovery shell, and at the same time, the rotating rod drives the collection shell to rotate in the recovery shell through the connecting rod.

At the same time, after the spraying and flushing work of the cylinder head is completed, when the dual-axis motor stops working, the baffle plate is reset by the second spring to offset the arc plates on both sides, and at the same time, the two sides of the semicircular plate are offset against the inner side of the collection shell, thereby preventing the impurities in the collection shell from flowing out.

[0015] A process for spray washing of an engine cylinder head comprises the following steps:

[0016] S1: The operator hoists the engine cylinder head into the cleaning tank by placing the parts;

[0017] S2: By opening the storage component, the engine cylinder head is flushed from multiple angles and in all directions to ensure that the dirt is completely removed;

[0018] S3: The water flow during the cylinder head flushing enters the recovery component for secondary recovery treatment;

[0019] S4: After cleaning is completed, the placed parts are lifted out of the cleaning tank and the cylinder head is blown dry by external equipment to remove residual moisture on the surface and prevent the cylinder head from rusting.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention sets a storage component and starts a water pump to draw the treated water in the recovery shell into the storage shell through a filtering mechanism, and sends the water in the storage shell to the spray mechanism through a connecting mechanism, so that the spray mechanism sprays and rinses the engine cylinder head hoisted in the cleaning tank.

[0022] 2. The present invention sets a filtering mechanism, starts a water pump, and performs extraction work of the water pump, thereby opening the first one-way valve and the second one-way valve, so that the water pump extracts the water flow in the recovery shell, and filters the water flow entering the filter tube through the filter plate, thereby preventing impurities mixed in the water flow from entering the filter tube. At the same time, through the extraction force of the water pump, the water flow enters the storage shell through the filter tube. At the same time, when the water flow passes through the filter tube, the impact force of the water flow can cause the bracket to drive the ejection assembly to move to the side away from the filter plate through the sliding rod, thereby preventing the ejection assembly from clogging the mesh holes of the filter plate, causing the water flow speed to decrease.

[0023] 3. The present invention sets a feeding mechanism. When the output end at the top of the dual-axis motor drives the stirring blade to rotate in the connecting shell through the rotating shaft, the stirring blade is squeezed and contacted with the extrusion block, so that the extrusion block drives the circular plate to move upward in the inner cavity of the feeding shell through the extrusion shaft. At the same time, the blocking block is driven to separate from the bottom of the feeding shell through the circular plate, so that the flocculating drug in the feeding shell falls through the gap formed by the blocking block separating from the inner side of the feeding shell, thereby adding drugs to the water flow passing through the connecting shell, and flocculating and precipitating impurities in the water flow after cleaning, so as to facilitate the subsequent filtering treatment of the water flow.

[0024] 4. The present invention sets a collecting mechanism, and the water flow after mixing with the medicine enters the recovery shell through the connecting shell, and the output end at the bottom of the dual-axis motor drives the rotating rod to rotate in the inner cavity of the recovery shell, and at the same time, the rotating rod drives the collection shell to rotate in the recovery shell through the connecting rod, and when the collection shell contacts and rotates with the water flow stored in the recovery shell, the water flow and the semicircular plate are squeezed and impacted, so that the semicircular plate drives the baffle to separate from the arc plates on both sides through the sliding rod, so that the water flow mixed with impurities enters the collection shell, and at the same time, circular holes are evenly opened on the side of the collection shell, so that the impurities mixed with the water flow enter the collection shell for collection, the water flow flows out through the circular holes, and the impurities enter the collection shell for collection, and at the same time, after the spraying and flushing work of the cylinder cover is completed, when the dual-axis motor stops working, the baffle is reset by the second spring to offset the arc plates on both sides, and at the same time, the two sides of the semicircular plate are offset against the inner side of the collection shell, thereby preventing the impurities in the collection shell from flowing out.

When the scraper 4486 contacts and cleans the inner wall of the mesh holes of the filter plate 444, the squeezing force between the scraper 4486 and the impurities on the inner wall of the mesh holes is greater than the tensile force of the fourth spring 4487, so that the round rod 4484 drives the scraper 4486 to slide in the notch 4482 through the slider 4483, and at the same time, the second spring 587 works as a buffer, thereby preventing the scraper 44 The squeezing force between the filter 444 and the impurities is too large, which will cause squeezing and wearing of the inner wall of the mesh of the filter plate 444, and then expand the inner diameter of the mesh of the filter plate 444, thereby reducing the service life of the filter plate 444. By symmetrically arranging the scraper 4486 on the round rod 4484, when the water flows through the filter tube 441, the ejection rod 4481 is driven to separate from the mesh of the filter plate 444, and the mesh of the filter plate 444 can be cleaned for the first time through the scraper 4486, thereby avoiding the residual dry sludge on the inner wall of the mesh of the filter plate 444, which causes the water flow to slow down when the water flows through the filter plate 444.

The water flow in the storage housing 41 is drawn into the connecting pipe 421, and at the same time, the water flows in the connecting pipe 421, so that the cross 426 drives the scraper 4486 to move on the guide rod 425. At the same time, by pulling the fifth spring 428, when the spraying and flushing work is completed and the extraction pump 422 stops extracting, the cross 426 is reset on the guide rod 425 by the stretching of the fifth spring 428, so that the cross 426 drives the contact plate 427 to clean the inner wall of the connecting pipe 421. During the flushing process, a small amount of dirt flushed from the surface of the engine cylinder head may remain on the inner wall of the connecting pipe 421 with a mixed water flow, such as mud impurities in the oil on the surface of the engine cylinder head. When the water flows through the connecting pipe 421, due to factors such as gravity and flow rate changes, it will adhere to the pipe wall. These precipitations will gradually accumulate, making the inner diameter of the connecting pipe 421 smaller, affecting the flow rate and pressure of the water flow, thereby causing the spraying effect to deteriorate and the engine cylinder head cannot be effectively flushed;

[0053] Example 3, using Figure 1-Figure 11 The spray washing device for an engine cylinder head of the present invention is described as follows;

[0054] like Fig.12 A process for spray washing of an engine cylinder head is shown, comprising the following steps:

[0055] S1: The operator hoists the engine cylinder head into the cleaning tank 2 by placing the component 3;

[0056] S2: By opening the storage component 4, the engine cylinder head is flushed from multiple angles and in all directions to ensure that the dirt is completely removed;

[0057] S3: The water flow during the cylinder head flushing enters the recovery component 5 for secondary recovery treatment;

[0058] S4: After the cleaning is completed, the placed component 3 is lifted out of the cleaning tank 2, and the cylinder head is blown dry by an external device to remove the residual moisture on the surface to prevent the cylinder head from rusting;

[0059] The specific workflow is as follows:

[0060] During operation, the engine cylinder head is hoisted and placed into the cleaning tank 2 through the placing component 3, and the engine cylinder head in the cleaning tank 2 is sprayed and rinsed by opening the storage component 4. At the same time, the sprayed and rinsed water is recycled through the recycling component 5;

[0061] The engine cylinder head is designed with screw holes specially used for lifting, and these screw holes can be installed with eyebolts. One end of the eyebolt is a screw with an internal thread, which cooperates with the screw hole of the cylinder head, and the other end is a ring structure. The hook 36 is hooked with the eyebolt on the engine cylinder head, and the hook is hooked with the pull ring 32 through the external lifting equipment, so as to carry out the lifting work. The engine cylinder head is lifted into the cleaning tank 2 by pulling the steel cable 35 through the placement frame 31, and the position of the engine cylinder head is placed by abutting the bottom of the placement frame 31 with the groove on the side of the cleaning tank 2, so as to facilitate the subsequent cleaning work;

[0062] By turning on the water pump 45, the treated water in the recovery shell 51 is pumped into the storage shell 41 through the filtering mechanism 44, and the water in the storage shell 41 is sent to the spraying mechanism 43 through the connecting mechanism 42, so that the spraying mechanism 43 sprays and rinses the engine cylinder head hoisted in the cleaning tank 2. The spraying mechanism 43 can adjust the angle to ensure that the cleaning liquid can cover all parts of the cylinder head. For some cylinder heads with complex shapes, multiple nozzles are required to spray from different angles. Fixed multi-angle nozzles can be used to achieve spraying at different angles to ensure that the grooves, channels and other parts of the cylinder head can be rinsed by the cleaning liquid.

[0063] By turning on the water pump 45 and performing the extraction work of the water pump 45, the first one-way valve 442 and the second one-way valve 443 are opened, so that the water pump 45 extracts the water flow in the recovery housing 51, and at the same time filters the water flow entering the filter tube 441 through the filter plate 444, thereby preventing impurities mixed in the water flow from entering the filter tube 441. At the same time, through the extraction force of the water pump 45, the water flow enters the storage housing 41 through the filter tube 441. At the same time, when the water flow passes through the filter tube 441, the impact force of the water flow can cause the bracket 446 to drive the ejection component 448 to move to the side away from the filter plate 444 through the slide rod 445, thereby preventing the ejection component 448 from clogging the mesh of the filter plate 444, causing the water flow speed to decrease.

[0064] When the extraction work of the water pump 45 is finished, the water pump 45 stops working, and the bracket 446 is driven to move toward the filter plate 444 by the third spring 447, so that the bracket 446 drives the ejector pin 4485 to eject the impurities blocked in the mesh of the filter plate 444 through the ejector rod 4481, thereby preventing the impurities mixed in the water flow from clogging the mesh of the filter plate 444 when the filter plate 444 performs filtering work for a long time. At the same time, the bracket 446 is continuously reset and pulled by the third spring 447, so that the bracket 446 drives the ejector rod 4481 to continuously move at the mesh of the filter plate 444, so that the scraper 4486 can clean the inner wall of the mesh of the filter plate 444, thereby preventing the sludge impurities mixed in the water flow from remaining in the mesh of the filter plate 444, thereby causing the mesh of the filter plate 444 to be blocked. When the scraper 4486 contacts and cleans the inner wall of the mesh of the filter plate 444, When the squeezing force between the scraper 4486 and the impurities on the inner wall of the mesh is greater than the tensile force of the fourth spring 4487, the round rod 4484 drives the scraper 4486 to slide in the notch 4482 through the slider 4483. At the same time, the second spring 587 works as a buffer, thereby preventing the squeezing force between the scraper 4486 and the impurities from being too large, which will cause squeezing and wear on the inner wall of the mesh of the filter plate 444, and further expand the inner diameter of the mesh of the filter plate 444, thereby reducing the service life of the filter plate 444. By symmetrically arranging the scraper 4486 on the round rod 4484, when the water flows through the filter tube 441, the ejection rod 4481 is driven to separate from the mesh of the filter plate 444, and the scraper 4486 can be used to perform the first cleaning work on the mesh of the filter plate 444, thereby preventing the inner wall of the mesh of the filter plate 444 from being left with dry sludge, thereby causing the water flow to slow down when the water flows through the filter plate 444.

[0065] By turning on the extraction pump 422, the water in the storage housing 41 is pumped into the connecting pipe 421 through the extraction pump 422, and the water flows in the connecting pipe 421, so that the cross 426 drives the scraper 4486 to move on the guide rod 425. At the same time, by pulling the fifth spring 428, when the spraying and flushing work is completed and the extraction pump 422 stops the extraction work, the cross 426 is reset on the guide rod 425 through the stretching of the fifth spring 428, so that the cross 426 drives The contact plate 427 cleans the inner wall of the connecting pipe 421. During the flushing process, a small amount of dirt washed off the surface of the engine cylinder head may remain on the inner wall of the connecting pipe 421. For example, sludge impurities in the oil on the surface of the engine cylinder head will adhere to the pipe wall due to factors such as gravity and flow rate changes when the water flows through the connecting pipe 421. These deposits will gradually accumulate, making the inner diameter of the connecting pipe 421 smaller, affecting the flow rate and pressure of the water flow, thereby causing the spraying effect to deteriorate and failing to effectively flush the engine cylinder head.

[0066] When the engine cylinder head is continuously flushed, the flushed water flows into the recovery shell 51 through the mesh plate 54, and the dual-axis motor 59 is turned on, through the output end at the top of the dual-axis motor 59, the stirring blade 56 is driven to rotate in the inner cavity of the connecting shell 53 through the rotating shaft 55, and at the same time, the stirring blade 56 is contacted and rotated with the feeding mechanism 57, so that when the flushed water flows through the connecting shell 53, the feeding mechanism 57 can feed the medicine into the passing water flow, and at the same time, the stirring blade 56 collides with the water flow mixed with the medicine, thereby increasing the reaction between the medicine and the water flow, accelerating the precipitation of the mixed sludge in the water flow, and at the same time, the water flow mixed with the medicine enters the recovery shell 51, and the collecting mechanism 58 is driven to rotate through the output end at the bottom of the dual-axis motor 59, so that the collecting mechanism 58 collects the impurities in the flushed water flow;

[0067] When the output end at the top of the dual-axis motor 59 drives the stirring blade 56 to rotate in the connecting shell 53 through the rotating shaft 55, the stirring blade 56 is squeezed and contacted with the extrusion block 573, so that the extrusion block 573 drives the circular plate 574 to move upward in the inner cavity of the feeding shell 571 through the extrusion shaft 572, and at the same time, the material blocking block 575 is driven to separate from the bottom of the feeding shell 571 through the circular plate 574, so that the flocculation drug in the feeding shell 571 is separated from the gap formed on the inner side of the feeding shell 571 by the material blocking block 575, so that the drug is added to the water flow passing through the connecting shell 53, and the impurities in the water flow after the cleaning work are flocculated and precipitated, so as to facilitate the subsequent filtering treatment of the water flow;

[0068] The water flow after mixing with the medicine enters the recovery shell 51 through the connecting shell 53, and the output end at the bottom of the dual-axis motor 59 drives the rotating rod 581 to rotate in the inner cavity of the recovery shell 51. At the same time, the rotating rod 581 drives the collecting shell 583 to rotate in the recovery shell 51 through the connecting rod 582. At the same time, when the collecting shell 583 contacts and rotates with the water flow stored in the recovery shell 51, the water flow and the semicircular plate 586 are squeezed and impacted, so that the semicircular plate 586 drives the baffle 585 to separate from the arc plates 588 on both sides through the sliding rod 584, so that the water flow mixed with impurities enters the collecting shell 5 83, circular holes 589 are evenly opened on the side of the collecting shell 583, so that impurities mixed with the water flow enter the collecting shell 583 for collection, the water flows out through the circular holes 589, and the impurities enter the collecting shell 583 for collection, and after the spraying and flushing work of the cylinder head is completed, when the dual-axis motor 59 stops working, the baffle 585 is reset by the second spring 587 and is offset against the circular arc plates 588 on both sides, and at the same time, the two sides of the semicircular plate 586 are offset against the inner side of the collecting shell 583, thereby preventing the impurities in the collecting shell 583 from flowing out.
