Description

Technical Field

[0001] This utility model relates to the field of oil pump technology, and in particular to an oil pump cleaning device. Background Technology

[0002] The oil pump is a core component of the engine lubrication system. Its core function is to draw oil from the oil pan through mechanical or hydraulic means, pressurize it, and deliver it to the various friction surfaces of the engine to ensure that each component is adequately lubricated, thereby reducing wear and controlling temperature. The application of oil pumps in internal combustion engines is increasing. The performance of the oil pump is directly related to the reliability and lifespan of the engine. After the oil pump is machined, the surface of the pump body is usually covered with impurities such as oil and iron filings, which need to be cleaned.

[0003] Existing cleaning devices mostly use direct rinsing or ultrasonic cleaning to clean oil pumps. The pump is placed in the cleaning tank through a basket or rack, cleaned, and then pulled out. However, during the cleaning process, part of the bottom of the pump body is always blocked by the rack or basket, preventing it from being completely rinsed. After ultrasonic cleaning, dirt contaminates the cleaning solution, and some wastewater remains on the surface of the pump during the removal process, resulting in incomplete cleaning. Therefore, we propose an oil pump cleaning device. Summary of the Invention

[0004] The problem this invention aims to solve is that the oil pump is easily blocked during cleaning and that residual sewage on the surface leads to incomplete cleaning.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an oil pump cleaning device, which includes a cleaning tank and an ultrasonic generator. A drain outlet is fixedly provided through the lower part of the cleaning tank away from the ultrasonic generator. Lifting plates are symmetrically slidably arranged inside the cleaning tank. A mesh plate bracket is symmetrically fixed to the bottom surface of the cleaning tank between two lifting plates. A connecting plate is fixed to the top surface of the front and rear ends of each lifting plate. Each connecting plate can be fixedly and slidably connected to the inside of a support plate. A lifting cylinder is fixedly installed on the lower part of the middle of the outer side of each support plate. The output end of each lifting cylinder is fixed to the bottom surface of the support plate.

[0006] As a preferred embodiment of the oil pump cleaning device of this utility model, a water spray pipe is fixedly installed on the inner side of the cleaning pool between the two lifting pallets. Each water spray pipe has several nozzles on the side facing the middle of the cleaning pool, and one end of each water spray pipe is fixedly extended to the outside of the cleaning pool.

[0007] In a preferred embodiment of the oil pump cleaning device of this utility model, the bottom surface of each lifting cylinder is fixed on the base plate, and a telescopic sleeve is fixed on the base plate on both sides of each lifting cylinder. A telescopic tube insert is slidably sleeved inside each telescopic sleeve, and the top surface of each telescopic tube insert is fixed on the bottom surface of the support plate.

[0008] In a preferred embodiment of the oil pump cleaning device of this utility model, both lifting trays are L-shaped, both mesh plate supports are inverted U-shaped, and the height of each mesh plate support is greater than the height of the lifting tray.

[0009] In a preferred embodiment of the oil pump cleaning device of this utility model, each of the connecting plates is fixed with a screw on its top surface, and each screw is fixed with a movable block on its top surface. The bottom of each movable block is slidably inserted into the adjustment groove opened in the support plate, and a fixing nut is threaded onto the screw on the bottom surface of the support plate.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Reference Figures 1-5 This embodiment is an oil pump cleaning device, including a cleaning tank 1 and an ultrasonic generator 2. A drain outlet 11 is fixedly installed through the lower part of the cleaning tank 1 away from the ultrasonic generator 2. Lifting plates 3 are symmetrically slidably arranged inside the cleaning tank 1. A mesh plate bracket 4 is symmetrically fixed on the bottom surface of the cleaning tank 1 between the two lifting plates 3. Both lifting plates 3 are L-shaped to facilitate direct placement of the oil pump. Both mesh plate brackets 4 are inverted U-shaped to facilitate support of the oil pump. The height of each mesh plate bracket 4 is greater than the height of the lifting plates 3, ensuring that after the lifting plates 3 fall to the bottom surface of the cleaning tank 1, the oil pump can be placed on the mesh plate bracket 4. This changes the placement point to ensure that the bottom of the oil pump can be thoroughly cleaned. Each lifting plate 3 has a connecting plate 5 fixed on the top surface of its front and rear ends. Each connecting plate 5 can be fixedly and slidably connected inside a support plate 6, allowing adjustment of the distance between the two lifting plates 3. A lifting cylinder 7 is fixedly installed on the lower middle part of the outer side of each support plate 6, and the output end of each lifting cylinder 7 is fixed to the bottom surface of the support plate 6.

[0021] In this embodiment, a water spray pipe 10 is fixedly installed on the inner side of the cleaning pool 1 between the two lifting pallets 3. Each water spray pipe 10 has several nozzles on the side facing the middle of the cleaning pool 1. One end of each water spray pipe 10 is fixedly extended to the outside of the cleaning pool 1. When the oil pump is pulled out of the cleaning fluid, the nozzles on both sides rinse the oil pump to clean the sewage remaining on the oil pump and avoid sewage residue on the surface of the oil pump after cleaning.

[0022] In this embodiment, the bottom surface of each lifting cylinder 7 is fixed to the base plate, and telescopic sleeves 8 are fixed on the base plates on both sides of each lifting cylinder 7. A telescopic tube rod 9 is slidably connected inside each telescopic sleeve 8, and the top surface of each telescopic tube rod 9 is fixed to the bottom surface of the support plate 6. The support plate 6 is raised and lowered under the control of the lifting cylinder 7, which drives the telescopic tube rod 9 to slide inside the telescopic sleeve 8, making the support plate 6 more stable when moving.

[0023] In this embodiment, each connecting plate 5 is fixed with a screw on its top surface, and each screw is fixed with a movable block 12 on its top surface. The bottom of each movable block 12 is slidably inserted into the adjustment groove 13 opened in the support plate 6. Each screw on the bottom surface of the support plate 6 is threaded with a fixing nut 14. During cleaning, the fixing nut 14 is turned to release the connection plate 5 from the support plate 6, and then the lifting pallet 3 can be pulled to adjust the distance between the two lifting pallets 3. This is convenient for adapting to oil pumps of different sizes, so that the two ends of the oil pump can be placed on the lifting pallet 3 while the pump body at both ends does not contact the side wall of the lifting pallet 3.

[0024] In this embodiment, each movable block 12 is configured as a T-shaped rectangle that cooperates with the adjustment groove 13. When the support plate 6 is pushed upward, the movable block 12 can be hooked onto the support plate 6 to ensure the stability of the connection between the connecting plate 5 and the support plate 6. The thickness of the bottom of each movable block 12 is less than the thickness of the adjustment groove 13, and the width of each fixing nut 14 is greater than the width of the adjustment groove 13.

[0025] In this embodiment, a valve is installed on the drain outlet 11. A filter cylinder 15 is fixed to the end of the drain outlet 11 away from the cleaning tank 1 by a flange and bolts. Inside the filter cylinder 15, filter cotton 16, ceramic filter media 17 and activated carbon filter plate 18 are fixedly installed from the drain outlet 11 end to the outside. During rinsing, the water level of the cleaning liquid inside the cleaning tank 1 is controlled by timely discharge of sewage from the cleaning tank 1, and the discharged cleaning liquid is filtered in time to facilitate subsequent recycling.

[0026] Working principle: When the oil pump needs cleaning, first adjust the distance between the two lifting plates 3 according to the size of the oil pump. During adjustment, tighten the fixing nuts 14 one by one to release the clamping fixation of the fixing nuts 14 on the support plate 6. Then pull the lifting plates 3 in opposite directions to adjust the distance between the two lifting plates 3. After adjustment, tighten the fixing nuts 14 to re-clamp the support plate 6. During cleaning, the lifting cylinder 7 moves and pushes the support plate 6 upward. When the support plate 6 moves upward, it drives the lifting plates 3 upward. After the lifting plates 3 move upward and are no longer above the surface of the cleaning fluid, place the oil pump at the bottom between the two lifting plates 3, ensuring that the sides of the oil pump are not in contact with the side walls of the lifting plates 3. The lifting cylinder 7 moves and drives the support plate 6 downward, allowing the oil pump to be lifted by the lifting plates 3. The oil pump slowly enters the cleaning fluid while the ultrasonic generator 2 is turned on to clean the oil pump. When the oil pump lands on the top surface of the mesh support 4, the lifting plate 3 continues to move downwards. At this time, the mesh support 4 supports the oil pump, and the contact between the oil pump and the lifting plate 3 is released, allowing the two ends of the oil pump to be cleaned. After cleaning, the lifting cylinder 7 operates to pull the lifting plate 3 upwards. When the lifting plate 3 moves upwards, it pulls out the oil pump. As the oil pump leaks out of the cleaning fluid, the water spray pipe 10 is opened to rinse the oil pump. At the same time, the valve on the drain outlet 11 is opened to drain the water. The discharged wastewater flows into the filter cartridge 15, and after being filtered by the filter cotton 16, ceramic filter media 17, and activated carbon filter plate 18, it is discharged into the recovery tank. The rinsed oil pump can then be removed.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
