Description

Technical Field

[0001] This invention relates to the field of automotive remanufacturing technology, specifically to a car remanufacturing bumper cleaning and treatment equipment. Background Technology

[0002] Automotive remanufacturing involves repairing and modifying used automotive parts, adhering to principles of high efficiency, energy conservation, material conservation, and environmental protection, to improve the performance of these components. In the remanufacturing process of bumpers, the old bumper parts undergo disassembly, cleaning, inspection, sorting, repair, and assembly. The cleaning of bumper components and the main structure must ensure that the surfaces of the parts are free of dust and oil.

[0003] A car bumper processing water washing device with patent publication number CN210125592U mainly includes a base, a housing, and a water pump and water tank located on the top of the housing. A powered roller conveyor is installed in the housing, and a water tank and drain pipe are provided at the bottom of the housing. A cleaning mechanism is connected to the top through a reciprocating mechanism. When the powered roller conveyor transports the bumper, the bumper is cleaned through the annular pipe and multiple nozzles in the cleaning mechanism. The reciprocating mechanism moves back and forth to make the cleaning more thorough.

[0004] However, the cleaning water from the aforementioned device is discharged directly through the water tank and drain pipe after use, and cannot be recycled or reused, which easily wastes the cleaning water. Furthermore, the annular pipe can only spray a single liquid at a time to clean the bumper, resulting in poor cleaning performance.

[0005] Based on this, the present invention designs a car remanufacturing bumper cleaning and processing equipment to solve the above problems. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to the accompanying drawings. This invention provides a technical solution: A car remanufacturing bumper cleaning and processing equipment, such as Figure 1 As shown, it includes a cleaning tank 100 and a base 301 fixed to the rear side of the bottom of the cleaning tank 100. A cylindrical processing box 300 is fixed to the top of the base 301. The upper part of the inner cavity of the cleaning tank 100 is provided with an adjustable conveying assembly 200. The middle and lower part of the inner cavity is divided into three cleaning tanks by two partitions 107, which are arranged in a straight line as the first cleaning tank 101, the second cleaning tank 102 and the third cleaning tank 103. A spray cleaning assembly is provided above the three cleaning tanks at the position corresponding to the adjustable conveying assembly 200. like Figure 3 As shown, the upper part of the processing box 300 is provided with a filter chamber 304, and the lower part is provided with three collection chambers, which are arranged sequentially along the circumferential direction as the first collection chamber 305, the second collection chamber 306, and the third collection chamber 307, as follows. Figure 11 As shown, the first collection chamber 305, the second collection chamber 306 and the third collection chamber 307 are respectively connected to the spray cleaning components in the first cleaning tank 101, the second cleaning tank 102 and the third cleaning tank 103 through the delivery pipe 109. The top of the inner cavity of the filter chamber 304 is connected to a circular cover plate 400 via a lifting structure. A vertical fixed cylinder 403 is fixed in the middle of the bottom of the cover plate 400. A filter element assembly is provided at the bottom of the filter chamber 304 corresponding to the internal position of the fixed cylinder 403. Three baffles 405 are evenly fixed along the circumferential direction on the outer side of the fixed cylinder 403. A multi-stage filtration structure is provided between two adjacent baffles 405. A backwashing assembly is provided at the top of the filter element assembly and the multi-stage filtration structure. The bottom ends of the fixed cylinder 403 and the baffle 405 are in contact with the bottom surface of the filter chamber 304, and the side of the baffle 405 is in contact with the side wall of the filter chamber 304. A sealing gasket can be set at the contact position to improve the sealing effect. The interior of the filter chamber 304 is divided into three fan-shaped filter grooves in the outer area of ​​the fixed cylinder 403 by the three baffles 405, and is sequentially set as the first filter groove, the second filter groove and the third filter groove along the circumferential direction. A connecting groove 406 is provided on the side wall of the fixed cylinder 403 corresponding to the position of the first filter groove. The upper part of the side wall of each of the three filter grooves is connected to a sewage pipe 308 and a sewage pump. A baffle can be set in the connecting groove 406. like Figure 10 As shown, the sewage pipe 308 of the first filter tank is connected to the third cleaning tank 103, and is connected to the first collection chamber 305 through the connecting groove 406 and the filter element assembly. The sewage pipe 308 of the second filter tank is connected to the first cleaning tank 101, and is connected to the second collection chamber 306 through the connecting hole 309 provided at the bottom. The sewage pipe 308 of the third filter tank is connected to the second cleaning tank 102, and is connected to the third collection chamber 307 through the connecting hole 309 provided at the bottom.

[0023] When cleaning the bumper, the bumper is loaded onto the adjustable conveyor assembly 200 via an external device or manually. The adjustable conveyor assembly 200 moves the bumper from the third cleaning tank 103 to the first cleaning tank 101. When passing through the third cleaning tank 103, the bumper is initially sprayed with clean water by the spray cleaning assembly there to remove dust and debris. When passing through the second cleaning tank 102, the bumper is sprayed with cleaning agent by the spray cleaning assembly there to remove residual oil and other substances, and to further clean stubborn dust. Finally, the bumper is sprayed with clean water by the spray cleaning assembly at the first cleaning tank 101, making the cleaning more comprehensive and thorough, and improving the cleaning effect.

[0024] When the first cleaning tank 101 subsequently rinses the bumper, residual cleaning agent on the bumper mixes into the cleaning wastewater, leaving some cleaning agent residue. This wastewater is then transported from the first cleaning tank 101 to the second filter tank via the wastewater pipe 308 at the bottom and the wastewater pump. After being filtered through a multi-stage filtration structure, the wastewater enters the second collection chamber 306. The wastewater in the second collection chamber 306 is then recycled through the delivery pipe 109 and the spray cleaning assembly on the second cleaning tank 102 to fully utilize the cleaning liquid. During the transportation of recycled water through the delivery pipe 109, cleaning agent is added to the wastewater through the cleaning agent storage structure to ensure the cleaning effect of the cleaning agent on the bumper.

[0025] The cleaning wastewater collected in the second cleaning tank 102 contains a lot of oil and impurities after cleaning agent treatment. The wastewater in the second cleaning tank 102 is transported to the third filter tank through the wastewater pipe 308 at the bottom and the wastewater pump. After being filtered by the multi-stage filtration structure, it enters the third collection chamber 307. The wastewater in the third collection chamber 307 is then recycled and reused through the conveying pipe 109 and the spray cleaning assembly on the third cleaning tank 103, so as to make full use of the cleaning water and reduce the waste of cleaning water. The wastewater collected in the third cleaning tank 103 contains most of the dust and debris. Through the wastewater pipe 308 at the bottom and the wastewater pump, the wastewater in the third cleaning tank 103 is transported to the first filter tank. After being filtered by the multi-stage filtration structure, it passes through the connecting channel 406 and enters the fixed cylinder 403. After being processed by the filter element assembly, it enters the first collection chamber 305, improving the wastewater treatment effect and making it meet the requirements of the first cleaning tank 101 for cleaning water. Then, it is recycled through the conveying pipe 109 and the spray cleaning assembly on the first cleaning tank 101, realizing the recycling and reuse of wastewater and reducing water waste.

[0026] When backwashing of the multi-stage filtration structure and filter element assembly is required, the lifting structure moves the cover plate 400, fixing cylinder 403, baffle 405, and multi-stage filtration structure upwards, sealing the bottom of the filter element assembly. Water in the first collection chamber 305 enters the filter element assembly through the backwashing assembly and is discharged outwards, achieving backwashing treatment. The top of the multi-stage filtration structure is also sprayed and cleaned through the backwashing assembly, ensuring that the filter element assembly and multi-stage filtration structure are cleaned, preventing blockages, and concentrating the backwash wastewater at the bottom of the filter chamber 304 for centralized discharge and treatment.

[0027] Among them, such as Figure 3 As shown, the filter element assembly includes vertical filter elements 500 fixed to the bottom surface of the filter chamber 304, and a drain hole is provided at the bottom center of each filter element 500 corresponding to the bottom of the filter chamber 304. The drain hole communicates with the first collection chamber 305. An end plate 501 is fixed to the top of the filter element 500. Figure 7 As shown, a vertical fixing pipe 502 is provided at the center of the end plate 501. The fixing pipe 502 is connected to the backwashing assembly. A sealing structure is provided inside the filter element 500 at the position corresponding to the drain hole. The top of the sealing structure passes through the fixing pipe 502 and is connected to the cover plate 400.

[0028] Wastewater that has undergone multi-stage filtration in the first filter tank enters the fixed cylinder 403 through the connecting channel 406 and is filtered by multiple filter elements 500. After filtration, it enters the first collection chamber 305 through the drain hole so that the first cleaning tank 101 can clean the bumper. When it is necessary to backwash the filter element 500, the cover plate 400 moves the sealing structure upward to close the drain hole, allowing the water of the backwashing component to enter the interior and then be discharged to the outside, thereby achieving backwashing of the filter element 500 and keeping the backwash wastewater inside the filter chamber 304 for easy centralized discharge.

[0029] Among them, such as Figure 7 As shown, the sealing structure includes a lifting shaft 503 vertically positioned at the center of the filter element 500. The top end of the lifting shaft 503 passes through the top end of the fixing tube 502 and is fixedly connected to the cover plate 400. The bottom end extends out of the filter element 500 and the drain hole, as shown. Figure 8 As shown, a sealing plate 505 is fixed thereon, and a sealing plug 504 is fixed on the upper part of the lifting shaft 503. The sealing plug 504 is slidably connected to the inside of the fixed pipe 502. When the cover plate 400 moves the lifting shaft 503 upward, the connection position of the sealing plug 504 with the fixed pipe 502 and the backwashing assembly is offset, and the sealing plate 505 moves upward to close the drain hole, so that the water of the backwashing assembly can enter the filter element 500 through the fixed pipe 502 and rinse outward.

[0030] Among them, such as Figure 10 As shown, the multi-stage filtration structure includes multiple filter plates 404 evenly arranged between two adjacent baffles 405. The pore size of the multiple filter plates 404 decreases sequentially, with the filter plate 404 near the connecting groove 406 or connecting hole 309 having the smallest pore size and the filter plate 404 near the sewage pipe 308 having the largest pore size. The inner end of the filter plate 404 is fixedly connected to the fixed cylinder 403, the outer end contacts the side wall of the filter chamber 304, and the bottom end contacts the bottom surface of the filter chamber 304. When the sewage pipe 308 enters the corresponding filter groove, it passes through the multiple filter plates 404 in sequence and then enters the fixed cylinder 403 through the connecting groove 406 or the corresponding collection chamber through the connecting hole 309, thus realizing multi-stage filtration of sewage. like Figure 9 As shown, the top outer end of the filter plate 404 is connected to the bottom of the cover plate 400 through a fixing block, and the end of the spray pipe 605 is fixedly connected to the fixing block. The fixing block improves the positional stability of the filter plate 404 and other structures.

[0031] Among them, such as Figure 3 As shown, the backwashing assembly includes a flushing pipe 601 vertically fixed at the center of the bottom of the filter chamber 304. The bottom end of the flushing pipe 601 extends into the first collection chamber 305 and is connected to a flushing pump 600. Multiple horizontal connecting pipes 602 are evenly fixed along the circumferential direction on the upper part of the flushing pipe 601. The positions of the connecting pipes 602 and the fixed pipes 502 correspond one-to-one and are fixedly connected to each other. like Figure 7 As shown, a circular fixed water tank 604 is provided at the bottom center of the cover plate 400. A vertical sliding tube 603 is fixed at the bottom center of the fixed water tank 604, and the top end of the rinsing pipe 601 is slidably connected in the sliding tube 603. A sealing gasket can be set on the inner side wall of the sliding tube 603 to improve the sealing between the rinsing pipe 601 and the sliding tube 603. Multiple spray pipes 605 are fixed on the circumferential side wall of the fixed water tank 604, and the positions of the spray pipes 605 correspond one-to-one with those of the filter plates 404. The spray pipes 605 are fixedly connected to the bottom of the cover plate 400, and one end passes through the fixed cylinder 403 and is located at the top of the corresponding filter plate 404. Multiple nozzles are evenly provided at the bottom of the spray pipes 605 corresponding to the positions of the filter plates 404.

[0032] When backwashing of the filter element assembly and multi-stage filtration structure is required, the cover plate 400 moves the fixed cylinder 403, fixed water tank 604 and other structures upward, so that the sealing structure opens the connection between the connecting pipe 602 and the fixed pipe 502 and seals the bottom of the filter element 500. Then, the water in the first collection chamber 305 is brought into the corresponding filter element 500 through the connecting pipe 602 and discharged outward by the flushing pump 600 and flushing pipe 601 to backwash the filter element 500. At the same time, water is sent to multiple spray pipes 605 through the sliding pipe 603 and fixed water tank 604 and sprayed onto the filter plate 404 at the corresponding position to spray and clean the filter plate 404.

[0033] Among them, such as Figure 10 As shown, a drain pipe 310 is provided on the side wall of the treatment box 300 at the bottom position of the filter chamber 304. The drain pipe 310 is connected to the filter chamber 304, and a valve is provided inside the drain pipe 310. When backwashing the multi-stage filtration structure and filter element assembly, the sewage and impurities at the backwashing point are discharged along the drain pipe 310 under the flushing action, making the sewage discharge faster and more convenient.

[0034] Example 2: The structure of this example is basically the same as that of Example 1, except that, as shown in Example 2... Figure 2 As shown, the adjustable conveyor assembly 200 includes two movable frames 201 symmetrically and parallelly arranged on the upper part of the cleaning tank 100. Two conveyor wheels 202 are symmetrically arranged and rotatably connected to each movable frame 201. A motor is connected to one of the conveyor wheels 202, and a conveyor belt 203 is connected to both conveyor wheels 202. The conveyor belt 203 has through holes evenly distributed on it. Figure 6 As shown, the conveyor belt 203 is provided with a limiting protrusion 204 along its length direction; like Figure 5 As shown, a support base 206 is fixed in the middle of the top of the partition 107. An adjusting screw 205 is rotatably connected to the support base 206. The two sides of the adjusting screw 205 have opposite threads and are respectively threaded to two movable frames 201. The two ends of the adjusting screw 205 are rotatably connected to the two side walls of the cleaning tank 100, and one end extends out of the cleaning tank 100 and is connected to a motor.

[0035] When conveying the bumper, the bumper is placed on two conveyor belts 203, and the two bottom ends of the bumper are limited by the limiting protrusions 204 on the two conveyor belts 203 to improve the positional stability during conveying and cleaning. Then, the conveyor wheel 202 and the conveyor belt 203 are driven by the motor to move the bumper from the third cleaning tank 103 to the first cleaning tank 101. After three cleanings, the cleaning effect is improved. The adjusting screw 205 can be rotated by the motor. By adjusting the threads of the screw 205 with opposite directions on both sides, the two moving frames 201 and the conveyor belts 203 can be moved inward or outward at the same time, thereby adjusting the position of the two conveyor belts 203 and the spacing between the two limiting protrusions 204 to accommodate different bumpers.

[0036] Example 3: The structure of this example is basically the same as that of Example 1, except that, as shown in Example 3... Figure 2 As shown, the spray cleaning assembly includes an upper cleaning pipe 104 evenly arranged above two conveyor belts 203. The middle part of the upper cleaning pipe 104 is horizontal, and the two side sections are bent downward and in a vertical state. The vertical section is located outside the moving frame 201. A horizontal water inlet pipe 106 is fixed at the bottom end of the upper cleaning pipe 104. The outer ends of multiple water inlet pipes 106 extend out of the cleaning tank 100 and are connected to a conveying pump 108. The conveying pump 108 is connected to a corresponding conveying pipe 109. The inner end of the water inlet pipe 106 passes through the moving frame 201 and is connected to a lower cleaning pipe 105. The shape of the lower cleaning pipe 105 corresponds to the shape of the upper cleaning pipe 104. The middle part is horizontal and the two side sections are vertical. Multiple nozzles are evenly arranged at relative positions on the upper cleaning pipe 104 and the lower cleaning pipe 105. On the other side wall of the cleaning tank 100, there is a fixed shaft corresponding to the position and shape of the water inlet pipe 106. The fixed shaft passes through the movable frame 201 on the corresponding side, and the ends of the upper cleaning pipe 104 and the lower cleaning pipe 105 away from the water inlet pipe 106 are fixed to the top of the fixed shaft, so as to provide a limiting and supporting function for the other ends of the upper cleaning pipe 104 and the lower cleaning pipe 105, thereby improving the overall positional stability of the upper cleaning pipe 104 and the lower cleaning pipe 105.

[0037] As the bumper is conveyed through the adjustable conveyor assembly 200 and passes through the corresponding spray cleaning assembly, the cleaning area formed between the upper cleaning pipe 104 and the lower cleaning pipe 105 roughly corresponds to the shape of the bumper. During movement and passage, the outer side of the bumper is cleaned through the multiple upper cleaning pipes 104, and the inner side of the bumper is cleaned through the multiple lower cleaning pipes 105, making the cleaning more thorough. It undergoes preliminary cleaning through the third cleaning tank 103, cleaning agent cleaning through the second cleaning tank 102, and then water cleaning through the first cleaning tank 101, improving the cleaning effect.

[0038] Example 4: The structure of this example is basically the same as that of Example 1, except that, as shown in Example 4... Figure 4 As shown, the lifting structure includes a fixed column 401 fixed at the center of the top of the cover plate 400. A top plate 402 is fixed to the top of the fixed column 401. The top plate 402 is located above the processing box 300 and extends out of the upper area of ​​the processing box 300 at both ends. Two protrusions 302 are symmetrically fixed to the upper part of the side wall of the processing box 300. The top of the protrusions 302 is connected to the bottom of the corresponding end of the top plate 402 through two hydraulic telescopic cylinders 303. The top plate 402 drives the fixed seat and the cover plate 400 to move vertically through the hydraulic telescopic rod, thereby realizing the lifting of the cover plate 400 and its bottom structure.
