DETAILED DESCRIPTION

[0043] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0045] Combine the following Figures 1 to 5 A complex flow channel cleaning device and a cleaning method according to an embodiment of the present invention are described in detail.

[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 component 102, a box 104, a steel shot mixing device 106, a water tank 108, a high-pressure pump 110, etc. The box 104 is arranged below the workpiece placement component 102, and is used to receive the waste liquid after cleaning. The steel shot mixing device 106 is used to achieve mixing of steel shots and high-pressure water, including a shot tank 1061, a water distributor 1062 connected to the shot tank 1061, one side of the water distributor 1062 is connected to the water inlet pipe 1063, and the other side is respectively connected to the first water distributor 1064 and the second water distributor 1065, the first water distributor 1064 is connected to the inner cavity of the shot tank 1061, and the second water distributor 1065 is built into the bottom plate of the shot tank 1061. Inside, it passes through the bottom of the shot 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 shots to the workpiece 202, so as to achieve the cleaning of the complex flow channels of the workpiece 202. The second water distribution pipe 1065 is fixedly connected to the built-in connecting pipe 1071. The built-in connecting pipe 1071 connects the second water distribution pipe 1065 with the inner cavity of the shot tank 1061, and is built into the bottom plate of the shot tank 1061. A pill mixing control assembly 1066 is provided on the second water distribution pipe 1065. The pill mixing control assembly 1066 includes a pill mixing handle 1066-1 and a control rod 1066-2 connected to the pill mixing handle 1066-1. A pill mixing hole 1066-3 is provided on the control rod 1066-2. The position of the pill mixing hole 1066-3 can be adjusted by rotating the pill mixing handle 1066-1. When the high-pressure pump 110 runs for a certain period of time or the pressure in the pill storage tank 1061 reaches a certain pressure, the pill mixing handle 1066-1 can be controlled to rotate so that the pill mixing hole 1066-3 connects the inner cavity of the pill storage tank 1061 with the second water distribution pipe 1065, thereby achieving mixed outflow of steel shots 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 pill storage tank 1061 is larger than the pressure in the second water distribution pipe 1065, so that the steel shots can be mixed into the high-pressure water under the action of pressure. One side of the pill storage tank 1061 is provided with an electric contact pressure gauge 1067, which is convenient for determining whether to connect the pill mixing hole 1066-3 according to the pressure detection situation, and on the other hand, it can play a role in detecting pipeline blockage. When the pressure rises linearly, it may be that the pipeline is blocked. The top of the pill storage tank 1061 is provided with a sealing cover 1068 with a pressure relief valve 1068-1, so that when the pressure rises linearly, it can be relieved to prevent the equipment from being damaged by excessive pressure. The water tank 108 is connected to the high-pressure pump 110, and the high-pressure pump 110 is connected to the water inlet pipe 1063 of the steel shot mixing device 106, and the water in the water tank 108 is pumped into the steel shot mixing device 106 by the high-pressure pump 110.Thus, high-pressure water-entrained steel shots are used to flush complex inner cavities. Stainless steel shots are soft and spherical, and under the buffering of water, they can peel off impurities on the surface of the product (such as sand coating, sand adhesion, welding slag, etc.) without damaging the product substrate. The entire flushing process can be completed in a short time, generally 2-3 minutes, and there is no residue after cleaning, which is conducive to the mass production of products.

[0047] Furthermore, if Figure 1 and Figure 5 As shown, a throttling check valve 1069 is provided between the water distributor 1062 and the first water distribution pipe 1064, and a throttling handle 1069-1 is provided on the throttling check valve 1069. Thus, the pressure in the shot storage tank 1061 can be controlled, and then the content of steel shot in the water-shot mixture sprayed toward the workpiece 202 can be adjusted, and the regulation is convenient and fast.

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

[0049] Furthermore, if Figure 2 and Figure 3 As shown, the lower part of the inner cavity of the pill storage tank 1061 is inverted frustum, which makes it easier for the steel pills to enter the mixing pill hole 1066-3 in sequence, and avoids the occurrence of pipeline blockage to a certain extent. A temperature probe 1070 is provided at the upper part of the inner cavity of the pill storage tank 1061 to facilitate temperature detection and further ensure safety.

[0050] Furthermore, the particle size of the steel shot in the shot storage tank 1061 is 0.4 mm, and the hole size of the shot mixing hole 1066-3 is 0.7-3.0 mm. Thus, the cleaning effect of the water-shot mixture on the complex flow channel of the workpiece 202 can be further guaranteed, and the substrate is not easily damaged, and the shot mixing hole 1066-3 is not easily blocked.

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

[0052] Furthermore, if Figure 1As shown, the box 104 is provided with a vibrating screen 1041 and a filter screen 1042 from top to bottom; the high-pressure resistant pipe 114 is installed on one side wall of the box 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 box 104; a water level probe is provided in the box 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 box 104, and the impurities are filtered by the vibrating screen 1041, and the steel shot and water fall on the filter screen 1042, and the water slowly passes through the holes of the filter screen 1042 into the bottom of the box 104. When the water level reaches a certain liquid level, the water level probe transmits information to the program, and the program automatically starts the self-priming pump 112 to suck the water of the box 104 into the water tank 108, forming a flushing water cycle. The steel shot that falls on the filter screen 1042 can be taken out through the window on the side of the box 104 and added back into the steel shot tank for recycling.

[0053] Furthermore, if Figure 1 As shown, the workpiece placement assembly 102 includes: a linear module 1021; a linear power module 1022, fixedly mounted above the linear module 1021; a movable disk 1023, mounted on one side of the linear module 1021; a sleeve 1024, mounted on the movable disk 1023; a rotary power module 1025, mounted on the sleeve 1024; and a pneumatic chuck 1026, connected to the rotary power module 1025 via a bearing, and the workpiece 202 is detachably placed on the pneumatic chuck 1026. Thus, the workpiece 202 is placed on the pneumatic chuck 1026 through the foot switch, and the program is started. The program controls the linear power module 1022 above the linear module 1021 to drive the movable disk 1023 to move downward. At the same time, the program controls the rotary power module 1025 to rotate the product workpiece 202 on the pneumatic chuck 1026 through the shaft until it reaches the specified position. When cleaning the porous and complex inner cavity workpiece 202, there is no need to block the porous holes. Only the cleaning position, shot output and water pressure of the workpiece 202 need to be adjusted to achieve rapid overall cleaning.

[0054] A complex channel cleaning method according to an embodiment of the present invention uses a complex channel cleaning device according to any one of the above embodiments, comprising the following steps: placing a workpiece on a pneumatic chuck, controlling a linear power module to drive a movable disk to move downward, and controlling a rotary power module to drive the workpiece on the pneumatic chuck to rotate until it reaches a specified position;

[0055] After the workpiece reaches the designated position, the high-pressure pump is controlled to start, and the water in the water tank is pressurized by the high-pressure pump and enters the water distributor through the water inlet pipe. A part of it enters the pill storage tank through the throttling check valve on the first water distribution pipe, and the other part enters the high-pressure resistant pipe through the second water distribution pipe and sprays to the workpiece;

[0056] When the electric contact pressure gauge reaches the specified pressure, the pill mixing handle is controlled to rotate to connect the pill mixing hole. The water-pill mixture in the pill storage tank passes through the built-in connecting pipe and the pill mixing hole into the second water distribution pipe, and is sprayed to the workpiece through the high-pressure resistant pipe, nozzle and spray head to clean the corresponding position.

[0057] Thus, high-pressure water can be used to carry steel shots to flush complex inner cavities. 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, generally 2-3 minutes. Moreover, there is no residue after cleaning, which is conducive to the mass production of products.

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

[0059] According to the cleaning situation, control and adjust the throttling check valve to control the pressure in the pill storage tank and adjust the pill-water ratio;

[0060] If the pressure of the electric contact pressure gauge rises linearly, the pressure relief valve is controlled to open to release the pressure.

[0061] Thereby, the safety and reliability of the cleaning process are further guaranteed, the cleaning quality is further guaranteed, and the water and steel shots can be recycled, which further saves resources and reduces production costs.
