Description

Technical Field

[0001] The invention relates to the technical field of valve recycling and remanufacturing, in particular to a waste valve body recycling production line. Background Art

[0002] Valve remanufacturing refers to the process of reassembling valves after they have completed a life cycle by machining their main components (castings) according to manufacturing standards, replacing other components, and then inspecting them to meet all qualified standards. Valves, as pipe fittings that control fluid delivery, are widely used in industries such as petrochemicals, thermal power, nuclear power, and pharmaceuticals. Before the invention and promotion of valve remanufacturing, valves were simply dismantled and replaced with new ones after a life cycle. Most old valves were directly used as scrap materials and became raw materials for smelting, which was a huge waste of resource utilization and corporate costs. The emergence of valve remanufacturing technology has changed this situation. Companies can restore the full performance required for safe operation of most original valves at a much lower cost, while also improving the utilization rate of natural resources for society.

[0003] However, there is currently no relevant waste valve recycling line process, and waste valves cannot be effectively transformed and reused, resulting in the valve recycling process being still relatively backward. Moreover, when cleaning the disassembled valve parts, the various parts of each valve are mixed together for cleaning. After cleaning, the parts of the same valve must be sorted, which is bound to increase the workload of valve recycling and reduce work efficiency. In addition, the flushing process is not only relatively simple, but also has a general cleaning effect. Therefore, it is difficult to clean the valve effectively and thoroughly, which is bound to affect the quality of the recycled valve. Summary of the Invention

The unloading infrared switch 20 is electrically connected to the second cylinder 1701 and the unloading infrared switch 20 through a wire respectively.

[0077] The working principle is as follows: after the disassembled valve parts are loaded into the net bag 22, the opening of the net bag 22 is closed and placed on the feeding conveyor 2 at a certain interval, and transported to the baffle plate 1603 through the feeding conveyor 2 and the unloading conveyor 3. The baffle plate 1603 can intercept the transported net bag 22 between the push plate 1602 and the feeding window 1801 on this side. At the same time, the chain conveyor line 102 is started and runs in a counterclockwise direction. During this process, the chain conveyor line 102 can drive the peripheral conveying roller 10 to run synchronously through the telescopic bracket 9. After each telescopic bracket 9 is transported to the feeding device 16 , the conveying roller 10 on the telescopic bracket 9 just moves to the first support plate 402, and at the same time the telescopic bracket 9 will trigger the feeding infrared switch 19. At this time, the feeding infrared switch 19 will start the first cylinder 1601, and make the telescopic end of the first cylinder 1601 extend and retract once, and drive the push plate 1602 to slide back and forth. During this process, the push plate 1602 can push the corresponding net bag 22 through the material passing window 1801 to the conveying roller 10 moved there, thereby achieving the purpose of automatically pushing the net bag 22 on the feeding conveying device 2 into the moving conveying roller 10 in turn, and then achieving the purpose of automatic cyclic feeding;

[0078] After loading, the conveying roller 10 filled with the net bag 22 will be transported by the chain conveyor line 102 to the direction of the unloading conveying device 3. At the same time, the roller 21 will move along the guide rail 8, and in this process, the conveying roller 10 will drive the net bag 22 with valve parts to pass through the rough washing box 4, the fine washing box 5 and the flushing component 6 in turn. When passing through the rough washing box 4, the roller 21 will slide downward under the action of the inclined section on the left side of the first bending part 802. At this time, the roller 21 will drive the sleeve 903 to move downward on the support rod 902, and the sleeve 903 will drive the conveying roller 10 to move downward synchronously to the inside of the rough washing box 4. The interior of the rough washing box 4 is filled with cleaning water. Therefore, after the conveying roller 10 enters the rough washing box 4, the net bag 22 and its The internal valve parts will be immersed in the cleaning water and continue to move toward the unloading conveying device 3 under the drive of the chain conveyor line 102, thereby cleaning the valve parts in the net bag 22. At the same time, the motor 14 drives the front and rear impellers 13 to rotate, and drives the cleaning water in the rough washing box 4 to flow. The flowing cleaning water can improve the cleaning effect by flushing the valve parts. When the conveying roller 10 moves to the right inclined section of the first bending portion 802, it can drive the roller 21, the sleeve 903 and the conveying roller 10 to slide upward out of the rough washing box 4 under its guidance, thereby achieving the purpose of sequentially rough cleaning of the valve parts in each net bag 22, and removing impurities that are easy to clean on the valve parts first;

[0079] The valve parts that have undergone rough washing are continuously moved to the fine washing box 5 along with the conveying roller 10 under the action of the chain conveyor line 102. Similar to the rough washing conveying process, the conveying roller 10 and the valve parts can be immersed in the cleaning water in the fine washing box 5 under the guidance of the second bent portion 803. At the same time, the ultrasonic wave generated by the ultrasonic generator 15 can act on the valve parts, thereby performing ultrasonic fine washing on the valve parts. Then, the valve parts are moved out of the fine washing box 5 under the guidance of the second bent portion 803, thereby achieving the purpose of sequential ultrasonic fine washing of the valve parts and removing stubborn impurities on the valve parts.

[0080] The valve parts that have undergone ultrasonic fine cleaning are further conveyed by the chain conveyor line 102 to the bottom of the flushing assembly 6. At this time, the spray head 602 on the spray pipe 601 sprays water to spray and clean the valve parts, washing away the remaining impurities adhering to the outer surface. The spray water after flushing is collected by the water collection tank 7 below and discharged through the first drain pipe 23.

[0081] After the valve parts are sprayed, they will follow the telescopic bracket 9 and the conveying roller 10 to the upper surface of the second support plate 701, until they move to the unloading device 17. The telescopic bracket 9 will trigger the unloading infrared switch 20. At this time, the unloading infrared switch 20 will start the second cylinder 1701 and the electromagnet 1702. The start of the second cylinder 1701 will cause its telescopic end to extend and retract once, and drive the electromagnet 1702 to slide back and forth. When the electromagnet 1702 is energized, it will generate magnetic force. Therefore, when the second cylinder 1701 pushes the electromagnet After 1702 enters the conveying roller 10, it can adsorb the iron parts on the net bag 22, and then the second cylinder 1701 pulls the electromagnet 1702 to reset, and the net bag 22 and the valve parts inside it can be pulled out through the material transfer window 1801 to the unloading conveying device 3 through the iron parts, thereby achieving the purpose of removing the cleaned valve parts from the cleaning equipment. After the net bag 22 is taken out, the conveying roller 10 will be moved by the chain conveyor line 102 to the direction of the upward conveying device 2, and the next conveying and cleaning process will be carried out.

[0082] Example 3

[0083] The present invention provides Figure 5 、 Figure 8 and Figure 9 A waste valve body recycling line shown in the figure:

[0084] Racks 11 are provided above the roughing tank 4, the fine washing tank 5, and the water collecting tank 7. A support beam 1101 is provided at the lower part of the rack 11. A plurality of support legs 1102 are provided on the support beam 1101. The support legs 1102 are respectively fixed to the roughing tank 4, the fine washing tank 5, and the water collecting tank 7. A transmission device 12 connected to the conveying roller 10 is provided on the telescopic bracket 9.

[0085] The transmission device 12 includes a transmission shaft 1201 and a belt transmission assembly. The transmission shaft 1201 is rotatably connected to the telescopic bracket 9, and the outside of the transmission shaft 1201 is fixedly connected to a gear 1202 that is compatible with the rack 11. The belt transmission assembly is connected between the transmission shaft 1201 and the connecting shaft 904. The belt transmission assembly includes a driving wheel 1203, a driven wheel 1204 and a transmission belt 1205. The driving wheel 1203 is fixedly installed on the transmission shaft 1201, the driven wheel 1204 is fixedly installed on the connecting shaft 904, and the transmission belt 1205 is installed on the driving wheel 1203 and the driven wheel 1204. A protective cover 1206 is provided on the outside of the belt transmission assembly, and a rotating sealing device is provided between the transmission shaft 1201 and the protective cover 1206, and between the connecting shaft 904 and the protective cover 1206.

[0086] The working principle is as follows: when the chain conveyor line 102 of the conveying roller 10 moves and cleans inside the rough washing box 4 and the fine washing box 5 and on the water collecting box 7, the conveying roller 10 will move along the bottom wall of the rough washing box 4 and the fine washing box 5 and the upper surface of the water collecting box 7. During this process, the gear 1202 will engage with the rack 11 above the rough washing box 4, the fine washing box 5 or the water collecting box 7, and as the telescopic bracket 9 and the conveying roller 10 move slowly, the rack 11 will drive the gear 1202 and the transmission shaft 1201 to rotate, and the transmission shaft 1201 will drive the connecting shaft 904 and the conveying roller 10 to rotate through the driving wheel 1203, the transmission belt 1205 and the driven wheel 1204, and This is to make the valve parts inside the conveying roller 10 roll, thereby achieving the purpose of rolling and cleaning the valve parts, making the cleaning work more comprehensive, thorough and effective, and in the process of the valve parts rolling in the conveying roller 10, the protective gasket 1001 in the conveying roller 10 can provide a certain buffer for the rolling valve parts, thereby preventing the valve parts from being bumped; and because the size of the driving wheel 1203 is smaller than that of the driven wheel 1204, it can play a role of speed change, and make the rotation speed of the conveying roller 10 match the moving speed, avoiding friction between the conveying roller 10 and the rough washing box 4, the fine washing box 5 or the water collecting box 7 as much as possible, and ensuring the normal operation of the cleaning equipment.
