[0017] Preferably, the workpiece placement assembly includes: a linear module; a linear power module fixedly installed above the linear module; a movable disk installed on one side of the linear module; a sleeve installed on the movable disk; a rotary power module installed on the sleeve; and a pneumatic chuck connected to the rotary power module via a bearing, wherein the workpiece is detachably placed on the pneumatic chuck.

[0018] The technical solution of the present invention also provides a method for cleaning complex flow channels, comprising the following steps:

[0019] Place the workpiece on the pneumatic chuck, control the linear power module to drive the moving disk downward, and at the same time control the rotary power module to drive the workpiece on the pneumatic chuck to rotate until it reaches the designated position.

[0020] After the workpiece reaches the designated position, the high-pressure pump is turned on. The water in the water tank is pressurized by the high-pressure pump and enters the water distributor through the inlet pipe. Part of it enters the shot storage tank through the throttling check valve on the first water distributor pipe, and the other part enters the high-pressure resistant pipe through the second water distributor pipe and is sprayed onto the workpiece.

[0021] When the pressure gauge at the electrical contact reaches the specified pressure, the mixing handle is controlled to rotate, connecting the mixing hole. The water-shot mixture in the shot storage tank enters the second water distribution pipe through the built-in connecting pipe and the mixing hole, and is sprayed onto the workpiece through the high-pressure resistant pipe, nozzle and spray head for cleaning at the corresponding position.

[0026] (1) The complex flow channel cleaning device proposed in this invention realizes the flushing of complex internal cavities by high pressure water carrying steel shot without damaging the product substrate. The entire flushing process can be completed in a short time, generally 2-3 minutes. Moreover, there is no residue after cleaning, which is conducive to the mass production of products.

It only requires adjusting the workpiece cleaning position, shot output and water pressure to achieve rapid overall cleaning.

[0030] (5) The complex flow channel cleaning device proposed in this invention has a first water distribution pipe with a diameter larger than that of the second water distribution pipe, thereby making the pressure in the shot storage tank higher than that in the second water distribution pipe.

The effect is better and easier to control when the diameter of the first water distribution pipe is 1.5 times that of the second water distribution pipe.

[0031] (6) The complex flow channel cleaning device proposed in this invention can reuse steel shot and water.

[0033] (8) The complex flow channel cleaning method proposed in this invention uses a special complex flow channel cleaning device, which can realize the flushing of complex internal cavities by high pressure water carrying steel shot. Generally, after the high pressure pump is turned on for 5 seconds, the shot mixing hole is connected, and the entire flushing process can be completed in a short time, usually 2-3 minutes.

Detailed Implementation

[0043] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0045] The following is combined Figures 1 to 5 A detailed description is provided of a complex flow channel cleaning apparatus and cleaning method according to an embodiment of the present invention.

[0046] like Figures 1 to 5As shown, a complex flow channel cleaning device according to an embodiment of the present invention includes: a workpiece placement assembly 102, a housing 104, a steel shot mixing device 106, a water tank 108, a high-pressure pump 110, etc. The housing 104 is disposed below the workpiece placement assembly 102 and is used to receive waste liquid after cleaning. The steel shot mixing device 106 is used to mix steel shot with high-pressure water, and includes a shot storage tank 1061 and a water distributor 1062 connected to the shot storage tank 1061. One side of the water distributor 1062 is connected to a water inlet pipe 1063, and the other side is connected to a first water distributor pipe 1064 and a second water distributor pipe 1065 respectively. The first water distributor pipe 1064 is connected to the inner cavity of the shot storage tank 1061, and the second water distributor pipe 1065 is built into the bottom plate of the shot storage tank 1061. Inside, a high-pressure resistant pipe 114 passes through the bottom of the shot storage tank 1061 and is connected to the high-pressure resistant pipe 114. The high-pressure resistant pipe 114 is placed above the box body 104 to facilitate the spraying of high-pressure water containing steel shot onto the workpiece 202, thereby cleaning the complex flow channels of the workpiece 202. An internal connecting pipe 1071 is fixedly connected to the second water distribution pipe 1065. The internal connecting pipe 1071 connects the second water distribution pipe 1065 with the inner cavity of the shot storage tank 1061 and is built into the bottom plate of the shot storage tank 1061. A shot mixing control component 1066 is installed on the second water distribution pipe 1065. The shot mixing control component 1066 includes a shot mixing handle 1066-1 and a control rod 1066-2 connected to the shot mixing handle 1066-1. A shot mixing hole 1066-3 is opened on the control rod 1066-2. The position of the shot mixing hole 1066-3 can be adjusted by rotating the shot mixing handle 1066-1. When the high-pressure pump 110 runs for a certain period of time or the pressure in the shot storage tank 1061 reaches a certain pressure, the shot mixing handle 1066-1 can be controlled to rotate, so that the shot mixing hole 1066-3 connects the inner cavity of the shot storage tank 1061 and the second water distribution pipe 1065, thereby realizing the mixing and outflow of steel shot and water. The inner diameter of the first water distribution pipe 1064 is larger than the inner diameter of the second water distribution pipe 1065, so that the pressure in the shot storage tank 1061 is greater than the pressure in the second water distribution pipe 1065, thereby enabling the steel shot to mix into the high-pressure water under pressure. An electric contact pressure gauge 1067 is installed on one side of the shot storage tank 1061. This serves two purposes: firstly, it allows for determining whether the shot mixing hole 1066-3 is connected based on pressure readings; secondly, it detects pipe blockages, indicating a potential blockage if the pressure rises linearly. The top of the shot storage tank 1061 is equipped with a sealing cover 1068 with a pressure relief valve 1068-1, allowing for pressure relief when a linear pressure increase is detected, preventing damage from excessive pressure. A water tank 108 is connected to a high-pressure pump 110, which in turn is connected to the inlet pipe 1063 of the steel shot mixing device 106. The high-pressure pump 110 pumps water from the water tank 108 into the steel shot mixing device 106.This allows for the use of high-pressure water to carry steel shot to clean complex internal cavities. The stainless steel shot is soft and spherical, and with the buffer of water, it can remove impurities (such as sand, adhering sand, welding slag, etc.) from the product surface without damaging the product substrate. The entire cleaning process can be completed in a short time, generally 2-3 minutes, and there are no residues after cleaning, which is conducive to the mass production of products.

[0047] Furthermore, such as Figure 1 and Figure 5 As shown, a throttling check valve 1069 is installed between the water distributor 1062 and the first water distribution pipe 1064, and a throttling handle 1069-1 is installed on the throttling check valve 1069. This allows control of the pressure in the shot storage tank 1061, thereby adjusting the content of steel shot in the water shot mixture sprayed onto the workpiece 202, making regulation convenient and quick.

[0048] Furthermore, the inner diameter of the first water distribution pipe 1064 is 1.5 times that of the second water distribution pipe 1065, which makes it easier to push the water-particle mixture in the shot storage tank 1061 into the second water distribution pipe 1065 through the shot mixing hole 1066-3, and the effect is better and easier to control.

[0049] Furthermore, such as Figure 2 and Figure 3 As shown, the lower part of the inner cavity of the shot storage tank 1061 is shaped like an inverted frustum, which facilitates the sequential entry of steel shot into the mixing hole 1066-3 and to a certain extent avoids pipeline blockage. A temperature probe 1070 is installed in the upper part of the inner cavity of the shot storage tank 1061 for temperature detection, further ensuring safety.

[0050] Furthermore, the steel shot in the shot storage tank 1061 has a particle size of 0.4 mm; the diameter of the shot mixing hole 1066-3 is 0.7-3.0 mm. This further ensures the cleaning effect of the water-shot mixture on the complex flow channels of the workpiece 202, preventing damage to the substrate and reducing the likelihood of blockage in the shot mixing hole 1066-3.

[0051] Furthermore, such as Figure 1 As shown, the complex flow channel cleaning device also includes a self-priming pump 112, which is connected to the housing 104 and the water tank 108 through pipelines. During the cleaning process, the water in the housing 104 can be drawn back into the water tank 108 for recycling, which further saves energy and improves efficiency.

[0052] Furthermore, such as Figure 1As shown, the chamber 104 is equipped with a vibrating screen 1041 and a filter screen 1042 from top to bottom; a high-pressure resistant pipe 114 is installed on one side wall of the chamber 104, and the end of the high-pressure resistant pipe 114 below the workpiece 202 is connected to a nozzle 116; a steel shot outlet is provided on one side of the chamber 104; a water level probe is installed inside the chamber 104, and the position of the water level probe is lower than the position of the filter screen 1042. Thus, the cleaned water, steel shot, impurities, etc. fall into the chamber 104. After passing through the vibrating screen 1041, the impurities are filtered out, and the steel shot and water fall onto the filter screen 1042. The water slowly enters the bottom of the chamber 104 through the holes of the filter screen 1042. When the water level reaches a certain level, the water level probe transmits the information to the program, and the program automatically starts the self-priming pump 112 to draw the water from the chamber 104 into the water tank 108, forming a rinsing water circulation. Steel shot that falls above the filter screen 1042 can be removed through the window on the side of the housing 104 and added back into the steel shot tank for recycling.

[0053] Furthermore, such as Figure 1 As shown, the workpiece placement assembly 102 includes: a linear module 1021; a linear power module 1022, fixedly installed above the linear module 1021; a movable disk 1023, installed on one side of the linear module 1021; a sleeve 1024, installed on the movable disk 1023; a rotary power module 1025, installed on the sleeve 1024; and a pneumatic chuck 1026, connected to the rotary power module 1025 via a bearing, wherein the workpiece 202 is detachably placed on the pneumatic chuck 1026. Thus, by placing the workpiece 202 on the pneumatic chuck 1026 via a foot switch and starting the program, the program controls the linear power module 1022 above the linear module 1021 to drive the moving disk 1023 downward. At the same time, the program controls the rotary power module 1025 to drive the product workpiece 202 on the pneumatic chuck 1026 to rotate until it reaches the designated position. When cleaning the workpiece 202 with a complex internal cavity and multiple holes, there is no need to block the holes. Only the cleaning position of the workpiece 202, the shot output, and the water pressure need to be adjusted to achieve rapid overall cleaning.

[0054] A complex flow channel cleaning method according to an embodiment of the present invention, using any of the complex flow channel cleaning devices in the above embodiments, includes the following steps: placing the workpiece on a pneumatic chuck, controlling the linear power module to drive the moving disk to move downward, and simultaneously controlling the rotary power module to drive the workpiece on the pneumatic chuck to rotate until it reaches the designated position;

[0055] After the workpiece reaches the designated position, the high-pressure pump is turned on. The water in the water tank is pressurized by the high-pressure pump and enters the water distributor through the inlet pipe. Part of it enters the shot storage tank through the throttling check valve on the first water distributor pipe, and the other part enters the high-pressure resistant pipe through the second water distributor pipe and is sprayed onto the workpiece.

[0056] When the pressure gauge at the electrical contact reaches the specified pressure, the mixing handle is controlled to rotate, connecting the mixing hole. The water-shot mixture in the shot storage tank enters the second water distribution pipe through the built-in connecting pipe and the mixing hole, and is sprayed onto the workpiece through the high-pressure resistant pipe, nozzle and spray head for cleaning at the corresponding position.

[0057] This allows for the use of high-pressure water to carry steel shot to flush complex internal cavities. Generally, the mixing hole is connected 5 seconds after the high-pressure pump is turned on, and the entire flushing process can be completed in a short time, usually 2-3 minutes. Moreover, there are no residues after cleaning, which is conducive to the mass production of products.

[0058] Furthermore, the cleaning waste liquid that falls into the tank is filtered by a vibrating screen and a filter screen, and the water enters the bottom of the tank. When the water level reaches the specified level, the self-priming pump is controlled to draw the water into the water tank for reuse.

[0059] Depending on the cleaning situation, control and adjust the throttling check valve to control the pressure inside the shot storage tank and adjust the shot-to-water ratio;

[0060] If the pressure on the electric contact pressure gauge rises linearly, the pressure relief valve will be opened to release the pressure.

[0061] This further ensures the safety and reliability of the cleaning process, further guarantees the cleaning quality, and allows both water and steel shot to be recycled, further saving resources and reducing production costs.
