Abstract
Description
Technical Field
[0001] This utility model relates to a new energy vehicle production line, and more particularly to a penetration cleaning system. Background Technology
[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.
[0003] We need to perform penetrant cleaning on the steering knuckle of a new energy vehicle. Only after the penetrant on the surface of the steering knuckle can it be observed in a darkroom. During the cleaning process, the water pressure may be uncontrollable. If the water pressure is too high, the penetrant on the surface may also be washed away, making it impossible to detect defects in the workpiece. This will make it difficult to trace back later and affect production efficiency.
[0004] Meanwhile, existing infiltration cleaning systems typically only have one filter connected to them. After filtration, water is directly sprayed onto the system. When the filter becomes clogged and the pressure drops, it may result in incomplete cleaning, which still affects production efficiency.
[0005] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content
[0006] The purpose of this invention is to provide a permeation cleaning system that can ensure water pressure through a separate filtration mechanism and achieve traceability by monitoring the water pressure.
[0007] To achieve the above objectives, this utility model discloses a penetration cleaning system, which includes:
[0008] Sprinkler pump;
[0009] A spray pipe is connected to the spray water pump, and a spray head is provided at the downstream end of the spray pipe.
[0010] A coarse washing tank is provided, in which a cleaning area is formed. The spray head is disposed in the coarse washing tank and is oriented toward the cleaning area.
[0011] A secondary tank, which is connected to the coarse washing tank and to the upstream end of the spray pipe;
[0012] A filtration mechanism, comprising a water inlet pipe, a filter, and a return water pipe, wherein the upstream end of the water inlet pipe is connected to the secondary tank, the downstream end of the water inlet pipe is connected to the upstream end of the filter, the upstream end of the return water pipe is connected to the downstream end of the filter, and the downstream end of the return water pipe is connected to the secondary tank.
[0013] The monitoring mechanism includes a pressure sensor, a PLC, and a detection device. The pressure sensor is installed on the spray pipe downstream of the spray pump. The pressure sensor is electrically connected to the PLC, and the PLC is electrically connected to the detection device.
[0014] As a further description of the above technical solution, the water inlet pipe is used to introduce the sewage in the secondary tank into the filter for filtration, and the water return pipe is used to discharge the water filtered by the filter back into the secondary tank.
[0015] As a further description of the above technical solution, the bottom of the coarse washing tank is connected to a drain outlet controlled by a manual gate valve.
[0016] As a further description of the above technical solution, a manual gate valve is connected to each of the upstream and downstream sides of the spray pump.
[0017] As a further description of the above technical solution, a manual gate valve is connected to each of the upstream and downstream sides of the filter.
[0018] As a further description of the above technical solution, it also includes a level gauge and a temperature probe, which are disposed in the secondary tank.
[0019] As a further description of the above technical solution, the connection point between the secondary tank and the upstream end of the spray pipe is located at the bottom of the secondary tank.
[0020] As a further description of the above technical solution, the upstream end of the water inlet pipe is connected to the sub-channel at the bottom of the sub-channel, and the downstream end of the return water pipe is connected to the sub-channel at the top of the sub-channel.
[0021] Based on the above technical solution, the beneficial effects of this utility model are as follows:
[0022] This invention's infiltration cleaning system ensures water pressure through a separate filtration mechanism. Compared to existing infiltration cleaning systems that typically only have one filter and directly spray water after filtration (which may result in incomplete cleaning if the filter becomes clogged and the pressure drops), this invention features two parallel filters, with the filtration mechanism filtering water independently. Even if the pressure drops, it does not affect the spray water pressure. Furthermore, this invention utilizes a monitoring mechanism to detect water pressure and achieve traceability. A pressure sensor replaces the conventional pressure gauge and is connected to a PLC to record pressure data, enabling traceability and high recordability.

[0035] It should be understood that while terms such as "first," "second," and "third" may be used in this document to describe various components or signals, these components or signals should not be limited by these terms. These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.
[0036] Please see Figure 1 This embodiment provides a permeation cleaning system, which includes:
[0037] Sprinkler pump 1;
[0038] Spray pipe 2 is connected to spray water pump 1, and spray head 21 is located at the downstream end of spray pipe 2.
[0039] A coarse washing tank 3 forms a cleaning area, and a spray head 21 is installed inside the coarse washing tank and is oriented towards the cleaning area.
[0040] Sub-tank 4 is connected to coarse washing tank 3 and to the upstream end of spray pipe 2.
[0041] The filtration mechanism 5 includes a water inlet pipe 51, a filter 52, and a return water pipe 53. The upstream end of the water inlet pipe 51 is connected to the secondary tank 4, the downstream end of the water inlet pipe 51 is connected to the upstream end of the filter 52, the upstream end of the return water pipe 53 is connected to the downstream end of the filter 52, and the downstream end of the return water pipe 53 is connected to the secondary tank 4.
[0042] The monitoring mechanism 6 includes a pressure sensor 61, a PLC 62, and a detection device 63. The pressure sensor 61 is installed on the spray pipe 2 downstream of the spray pump 1. The pressure sensor 61 is electrically connected to the PLC 62, and the PLC 62 is electrically connected to the detection device 63.
[0043] With the above structure, during use, the operator only needs to place the steering knuckle device to be cleaned in the preset cleaning area in the coarse washing tank 3 and start the penetration cleaning system of this embodiment. Specifically, a certain amount of clean water is supplied into the system pipeline, the spray water pump 1 is started, so that the water flows along the spray pipe 2 to the spray head 21, and sprays from the spray head 21 onto the surface of the steering knuckle device to clean its surface. Then, the cleaned wastewater falls into the coarse washing tank 3 and flows downstream to the secondary tank 4. It is then poured into the filter 52 of the filter mechanism 5 through the water inlet pipe 51 for filtration. The filtered clean water flows back to the secondary tank 4 from the return water pipe 53. Simultaneously, the water in the secondary tank 4 enters the next circulation flow from the spray pipe 2.
[0044] Thus, this embodiment simultaneously achieves the cleaning of the steering knuckle device and the filtration of wastewater. During this process, when water flows through the pressure sensor 61 of the monitoring mechanism 6, the water pressure information is converted into a 4-20mA analog signal and output to the analog input module of the PLC 62. The PLC 62 converts the received analog signal into a digital signal through a program, and the pressure is displayed in real time on the detection device 63. Based on the signal provided by the PLC 62, the detection device 63 displays the spray pressure in real time on its display and shows a curve, providing operators with an intuitive display of the water pressure and enabling traceable recording.
[0045] During the above-mentioned use, the water pressure can be guaranteed by the separate filtration mechanism 5. Compared with the existing infiltration cleaning system, which is generally connected to only one filter and directly sends water for spraying after filtration, when the filter is clogged and the pressure drops, it may lead to incomplete cleaning. In this utility model, two paths run in parallel, and the filtration mechanism 5 filters water independently. Its pressure drop does not affect the spray water pressure. At the same time, this utility model uses the monitoring mechanism 6 to detect water pressure and achieve traceability. The pressure sensor 61 replaces the conventional water pressure gauge and is connected to the PLC 62 to record the pressure and achieve traceability. The recordability is high.
[0046] In this embodiment, the coarse washing tank 3 is designed as a regular rectangular barrel structure. The coarse washing tank 3 has sufficient internal cavity to form a cleaning area adequate for placing the workpiece to be cleaned, and provides sufficient space around the cleaning area to accommodate the spray heads 21. This avoids potential physical impact damage to the spray heads 21 from foreign objects during direct placement of the workpiece, which could occur due to the narrow space within the coarse washing tank 3 and affect subsequent maintenance. Specifically, multiple spray pipes 2 can be configured within the coarse washing tank 3, surrounding the cleaning area, to achieve the best and most comprehensive cleaning effect on the workpiece.
[0047] In this embodiment, the secondary tank 4 can actually be considered as an extension of the bottom of the coarse washing tank 3, and its cross-sectional volume is as follows: Figure 1 As shown, the rough washing tank 3 is about one-fifth of the total area. Its main function is to form a buffer zone between the rough washing tank 3 and the filter mechanism 5, etc., so that the sewage in it can be circulated relatively independently without affecting the normal cleaning of the workpieces in the rough washing tank 3 on the other side, thus ensuring work efficiency.
[0048] The filtration mechanism 5 is located adjacent to the secondary tank 4. Therefore, the water in the secondary tank 4 directly participates in the water circulation of the filtration mechanism 5; in fact, the secondary tank 4 can be understood as part of the water circulation within the filtration mechanism 5. To this end, the inlet pipe 51 and the return pipe 53 are positioned on the same side of the secondary tank 4, with the inlet pipe 51 located at the bottom and the return pipe 53 at the top, creating a vertically circulating water system in the secondary tank 4. The pressure sensor 61 in the monitoring mechanism 6 can be configured as an electronic sensor that directly reflects real-time water pressure and is electrically connected to the PLC 62. This allows for rapid transmission of real-time water pressure information to the PLC 62, which is then displayed to the operator via the detection device 63.
[0049] In the above embodiments, the pressure sensor 61, PLC 62 and detection device 63 can be configured as an integrated mechanism connected to one side of the spray pipe 2, which can exist in the form of a control box and be protected by a certain structure. The detection device 63 has a display facing outwards.
[0050] Specifically, in the above structure, the rough washing tank 3 is constructed by assembling and welding stainless steel SUS304 plates with a thickness of 2mm; the spray pump 1 is a "Nanfang" brand pump with a head of 25 meters and a flow rate of 30m³ / h. 3 / hour; the spray pipeline 2 consists of a main pipe and branch pipes made of SUS304 material; the pressure sensor 61 has a measurement range of 0-600Kpa and an output signal of 4-20Ma; the PLC 62 is a Siemens S7-1500 series; the detection device 63 adopts MCGS with data copy function.
[0051] Furthermore, the water inlet pipe 51 is used to introduce the sewage in the secondary tank 4 into the filter 52 for filtration, and the water return pipe 53 is used to discharge the water filtered by the filter 52 back into the secondary tank 4. This ensures that fresh water is continuously generated in the secondary tank 4.
[0052] Furthermore, the bottom of the coarse washing tank 3 is connected to a drain outlet 31 controlled by a manual gate valve, which facilitates the removal of sediment from the bottom of the coarse washing tank 3 during maintenance.
[0053] Furthermore, a manual gate valve is connected to the upstream and downstream of the spray pump 1, which can be used for temporary maintenance and management of the spray pump 1. Similarly, a manual gate valve is connected to the upstream and downstream of the filter 52, which can be used for temporary maintenance and management or replacement of the filter 52.
[0054] Furthermore, it also includes a level gauge 41 and a temperature probe 42, which are installed in the sub-tank. Specifically, the level gauge 41 and the temperature probe 42 are vertically inserted into the sub-tank 4 in the vertical direction to realize the functions of water level detection and temperature detection in the sub-tank, so as to avoid the possibility of dry running of the spray pump 1 or damage to the spray pump 1.
[0055] Furthermore, the upstream end of the water inlet pipe 51 connects to the sub-tank 4 at the bottom of the sub-tank 4, and the downstream end of the return water pipe 53 connects to the sub-tank 4 at the top of the sub-tank 4. This allows for the efficient removal and filtration of contaminants from the wastewater even when sediment has accumulated. The upstream end of the sub-tank 4 connects to the spray pipe 2 at the bottom of the sub-tank 4. In this embodiment, the connection point is positioned slightly higher than the water inlet pipe 51 to ensure water pressure and flow rate while preventing contaminants from entering.
