Description

Technical Field

[0001] This utility model relates to the field of industrial equipment technology, and in particular to an automatic pipe cleaning device for liquid conveying systems. Background Technology

[0002] In industrial production processes, liquid transport systems (such as chemical fluid transfer, food and beverage bottling, or pharmaceutical raw material distribution) undertake the task of transporting various fluid media. The cleanliness of its core component—the pipeline—has a profound impact on product quality, equipment lifespan, and production safety. Liquid transport systems typically include stainless steel pipes, pumps, valves, and other components. During long-term fluid transport, residual media, impurities, and even microorganisms can easily adhere to the inner walls of the pipes.

[0003] Traditional manual cleaning of liquid transport pipelines has many insurmountable drawbacks: on the one hand, it is extremely labor-intensive. Faced with complex pipeline layouts (such as multi-layer pipelines and long-distance pipelines), a lot of manpower is required to repeatedly disassemble, flush, and wipe, which is inefficient and prone to incomplete cleaning due to fatigue; on the other hand, there are many dead corners on the inner wall of the pipeline (such as elbows, valve connections, and abrupt changes in pipe diameter), which are difficult for manual cleaning tools to reach. After residual dirt accumulates, it will cause problems such as pipeline blockage and fluid contamination.

[0004] In the existing technology, although some simple cleaning devices attempt to replace manual labor, such as directly connecting to external high-pressure water pipes for rinsing, they have obvious defects: they lack stable water supply and pressure regulation, the water flow impact force fluctuates greatly, which can easily damage the pipes; and they do not have effective filtration and sealing structures, so the cleaning water impurities can easily cause secondary pollution of the pipes, and water leakage leads to damp sites and waste of resources; at the same time, the cleaning device cannot be adapted to pipes of different diameters and directions, and has poor versatility.

[0031] The following is in conjunction with the appendix Figure 1-5 The present invention provides a more detailed description of an embodiment of an automatic pipe cleaning device for a liquid delivery system.

[0032] An automatic pipe cleaning device for a liquid delivery system, such as Figures 1 to 4 As shown, including

[0033] A support frame 1 is used to support and fix the cleaning device. A water supply component 4 for stably providing a clean water source and a control panel 5 for displaying the operating parameters of the device are installed on the support frame 1. The control panel 5 and the water supply component 4 are connected by an electrical signal.

[0034] Filter 2 is used to filter clean water. Filter 2 is located on one side of the support frame 1 and the bottom end of filter 2 is connected to the liquid delivery system. Filter 2 is set at an angle and a bend joint 21 is connected between filter 2 and the liquid delivery system.

[0035] The cleaning component 3 is used to clean the pipeline of the liquid delivery system. The cleaning component 3 includes a spray water pipe 31 and a curved hose 32. The spray water pipe 31 can be inserted into the inner cavity of the filter 2, and the spray water pipe 31 is connected to the water supply component 4 through the curved hose 32. The curved hose 32 and the spray water pipe 31 are connected by a clamp or thread, and a control valve 6 is provided at the connection between the curved hose and the water supply component 4.

[0036] Specifically, the support frame 1 is constructed using suitable metal profiles, which provides stable support for the entire cleaning device. The pneumatic diaphragm pump 42 of the water supply component 4 is fixed to the preset mounting position of the support frame 1 using conventional installation methods such as bolts, ensuring its operational stability. The control panel 5 is also fixed to the surface of the support frame 1 via a bracket or a directly compatible mounting structure, allowing operators to easily view and operate it.

[0037] Filter 2 has an internal filtration structure to intercept impurities in the clean water source. During operation, clean water supplied from the water supply unit 4 enters the inner cavity of filter 2 via the spray pipe 31. After being filtered by filter 2, the water flows into the liquid delivery system pipeline through the elbow joint 21 at the bottom. Due to the angled installation of filter 2, impurities are gradually deposited at the bottom of filter 2 or in specific filtration areas due to gravity and the direction of water flow. The elbow joint 21 is designed to accommodate the angled installation of filter 2 and to change the direction of water flow into the liquid delivery system pipeline, allowing for more efficient water flow within the pipeline, thus facilitating the cleaning operation.

[0038] The flexible hose 32 of the cleaning component 3 is bendable and deformable. During operation, when the spray pipe 31 undergoes minor position adjustments due to insertion into the filter 2 or equipment vibration, the flexible hose 32 deforms accordingly, ensuring continuous water supply. Simultaneously, a control valve 6 is installed at the connection between the flexible hose 32 and the water supply component 4. This valve can be controlled manually or automatically. When it is necessary to open or close the cleaning water supply, the control valve 6 is operated to control the flow of cleaning water into the spray pipe 31. For example, at the initial startup stage, the control valve 6 is opened to allow cleaning water to slowly enter the spray pipe 31, preventing excessive water flow from damaging the pipe; before cleaning is completed, the control valve 6 is closed to stop the water supply.

[0039] In this embodiment, as Figure 5 As shown, the end of the spray pipe 31 that is inserted into the filter 2 is set at an angle, and multiple spray holes 311 are evenly opened on the outer circumferential surface of the spray pipe, and the spray holes 311 are connected to the inner cavity of the spray pipe 31.

[0040] Specifically, the spray pipe 31 features an angled design for easy insertion. After insertion, it ensures a better fit between the spray pipe 31 and the inner cavity of the filter 2, guaranteeing the direction and range of water flow from the spray holes 311. When clean water supplied by the water supply component 4 enters the spray pipe 31, the water flows within its inner cavity. Because the spray holes 311 are connected to the inner cavity, water is sprayed out from the spray holes 311 under water pressure, creating a multi-directional, multi-position spraying effect. This sprayed water then enters the filter 2 and, via the bend connector 21, enters the liquid delivery system's pipeline, flushing and cleaning the inner wall of the pipeline.

[0041] The spray holes 311 can be designed in different shapes, such as round holes, rhomboid holes, or rectangular holes. Different shapes of spray holes 311 will result in different water spray patterns. For example, the water spray from round holes is relatively concentrated, while rhomboid holes and rectangular holes may disperse the water flow over a wider range. However, they can all serve to flush the inner wall of the pipe and remove dirt. In actual cleaning, spray pipes 31 with different spray hole designs can be selected according to the degree of dirt in the pipe, or the water supply pressure can be controlled to adjust the spray force and pattern of the water flow, thereby achieving effective cleaning of pipes with different levels of contamination.

[0042] In this embodiment, as Figure 5 , 6 As shown, a sealing assembly 7 is provided at the junction of the spray pipe 31 and the filter 2. The sealing assembly 7 surrounds the outer circumference of the spray pipe 31 and includes a sealing ring 71, a sealing ring 72, and a spring 73. The sealing ring 71 is composed of a stationary ring 711 and a rotating ring 712. The inner wall of the stationary ring 711 has an anti-rotation notch 713, which is used to cooperate with the anti-rotation structure on the filter 2 or the spray pipe 31 to prevent the sealing ring 71 from rotating during operation and ensure a stable sealing effect. One end of the rotating ring 712 is connected to the spring 73 seat, and the spring 73 is connected between the rotating ring 712 and the spring 73 seat.

[0043] Specifically, when the spray pipe 31 is inserted into the filter 2, the sealing ring 71 is compressed by the filter 2 and the spray pipe 31, the spring 73 is compressed, and a reverse elastic force is applied to the moving ring 712, causing the stationary ring 711 and the moving ring 712 to fit tightly against the connection between the filter 2 and the spray pipe 31. The sealing rings 72 are respectively fitted on the outer side of the stationary ring 711 and the inner side of the moving ring 712, further enhancing the sealing performance, sealing the gap at the connection, preventing the clean water from overflowing at the connection between the spray pipe 31 and the filter 2, ensuring that the clean water can enter the filter 2 and the liquid delivery system pipeline through the spray hole 311, improving cleaning efficiency and avoiding water waste.

[0044] It is worth noting that this sealing structure is a simplified form of mechanical seal. It uses the elasticity of spring 73 and the fit of sealing ring 72 and sealing ring 71 to prevent water from leaking from the connection point, ensuring that water can enter the pipeline to participate in cleaning during the cleaning process, improving water resource utilization and cleaning efficiency, while avoiding water leakage that could cause dampness around the equipment, affect the normal operation of the equipment and the safety of the operators.

[0045] In this embodiment, as Figure 2 As shown, the water supply component 4 includes a water supply pipe 41 and a pneumatic diaphragm pump 42. One end of the water supply pipe 41 is connected to the inlet of the pneumatic diaphragm pump 42, and the other end is connected to an external water source (such as a factory water supply system). The outlet of the pneumatic diaphragm pump 42 is connected to a flexible hose 32 via a water supply pipe 43. The water supply pipe 41 branches into a water delivery pipe 411 and a drainage pipe 412. The water delivery pipe 411 connects the water supply pipe 41 and the water supply pipe 43. One end of the drainage pipe 412 is connected to the water supply pipe 41, and the other end is connected to a drainage pipe 44. A one-way valve 8 is provided at the connection between the drainage pipe 412 and the drainage pipe 44.

[0046] Specifically, when the device starts the cleaning program, the pneumatic diaphragm pump 42 begins to work. The pneumatic diaphragm pump 42 uses compressed air as a power source (externally supplied compressed air enters the pump body through valves, etc.), causing the diaphragm inside the pump body to reciprocate, thus achieving the suction and delivery of water. Specifically, compressed air enters one side of the pump body's air chamber, pushing the diaphragm to one side, causing a change in the corresponding pump chamber volume, drawing water from the water supply pipe 41, and then, through the movement of the diaphragm on the other side, delivering the water via the water supply pipe 43 and the curved hose 32 to the spray pipe 31. In this process, the water supply pipe 411 serves as the main water delivery channel, ensuring the smooth flow of clean water to the cleaning component 3. When it is necessary to drain the residual water in the water supply pipe 41 or to drain the equipment for maintenance, the one-way valve 8 of the drain pipe 412 is opened. The residual pressure after the pneumatic diaphragm pump 42 stops or the external auxiliary pressure is used to discharge the water in the water supply pipe 41 through the drain pipe 412 and the drain pipe 44. The one-way valve 8 can prevent external impurities from flowing back into the water supply pipe 41 during drainage, ensuring the cleanliness of the water supply component 4.

[0047] In this embodiment, the filter 2 is installed obliquely on one side of the support frame 1, and its side near the top is connected to the sewage discharge pipe 9, which is connected to the liquid delivery system through the elbow joint 21.

[0048] Specifically, when the cleaning operation is completed or the filter 2 needs to be cleaned, open the sewage discharge pipe 9 and the manual operation valve 10 on the filter 2. Use the impact force of the water flow or external auxiliary suction to discharge the impurities and sewage deposited in the filter 2 through the sewage discharge pipe 9, thereby cleaning and maintaining the filter 2 and ensuring the cleanliness of the water source for subsequent cleaning.

[0049] It is worth noting that the control panel 5 is installed in a convenient and easily observable position on the support frame 1. It includes a display screen 51, control buttons 52, and a sensor interface 53. Before operation, the operator can set cleaning-related parameters (such as cleaning duration, pump start / stop commands, etc.) via the control buttons 52. The sensor interface 53 is used to connect pressure sensors, flow sensors, etc., and the collected signals are transmitted to the control panel 5 in the form of electrical signals. After receiving the signals, the control panel 5 displays the equipment operating parameters on the display screen 51, such as the working status of the pneumatic diaphragm pump 42, water supply flow rate, pressure, and other data. Simultaneously, the control panel 5 is electrically connected to the pneumatic diaphragm pump 42. According to a preset program or operator instructions, it sends electrical signals to control the start / stop and operating power of the pneumatic diaphragm pump 42, achieving automated control of the water supply process. For example, when abnormal water supply pressure is detected, the operating parameters of the pneumatic diaphragm pump 42 are automatically adjusted or an alarm signal is issued to ensure stable cleaning.

[0050] The working principle of this utility model:

[0051] When the pipeline needs cleaning after the liquid delivery system has completed its work, the cleaning program is initiated via control panel 5. Control panel 5 sends an electrical signal to activate pneumatic diaphragm pump 42, which then draws in external water and delivers it through water delivery pipe 41, water supply pipe 411, water supply pipe 43, and flexible hose 32 to spray water pipe 31. The cleaning water flows within the spray water pipe 31, is sprayed out through spray holes 311, and enters the inner cavity of filter 2. After being filtered by filter 2, the water flows through the angled bend joint 21 at the bottom of filter 2 and enters the pipeline of the liquid delivery system. The sprayed water flushes the inner walls of filter 2 and the liquid delivery system pipeline, removing and rinsing away dirt and impurities adhering to the inner walls of the pipeline. After cleaning, the manual operating valve 10 at the wastewater discharge pipe 9 of filter 2 and the bend joint 21 is opened. The residual water flow impact force is used to discharge the impurities deposited in filter 2 and the wastewater from the pipeline cleaning through wastewater discharge pipe 9.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
