Description

Technical Field

[0001] This utility model relates to the field of siphon technology, and in particular to a high-pressure water jet driven siphon system anti-leakage vacuum device. Background Technology

[0002] In the field of vacuum technology, siphon systems, as an efficient and economical liquid transportation method, are widely used in various scenarios such as industrial production, sewage treatment, and municipal water supply. Siphon systems achieve continuous liquid transportation by utilizing the pressure difference generated by the liquid level difference through the natural flow of liquid in the pipeline. Its core lies in maintaining a negative pressure state inside the system to ensure the continuous siphon effect. In recent years, with the continuous advancement of technology, siphon systems have made significant progress in structural design, material selection, and control strategies, effectively improving the stability and efficiency of the system.

[0003] However, in practical applications, traditional siphon systems still face a problem that urgently needs to be solved – air leakage caused by aging pipe joints, seal failure, or liquid level fluctuations. This problem directly affects the negative pressure maintenance capability of the siphon system, leading to siphon interruption and requiring frequent pump shutdowns for manual priming. This seriously affects the continuous operation efficiency and stability of the system. Especially in scenarios such as waterworks that require large-scale, continuous water supply, frequent interruptions of the siphon system can not only cause water pressure fluctuations but may even lead to water supply interruptions, causing great inconvenience to production and daily life. Utility Model Content

[0004] To address the aforementioned technical deficiencies, this invention provides a high-pressure water jet-driven siphon system anti-leakage vacuum device, which effectively solves the problem of siphon tanks being affected by air leakage during normal operation.

[0005] This utility model discloses a high-pressure water jet driven siphon system anti-leakage vacuum device, including a water storage tank, an installation platform, and a siphon tank. The siphon tank is fixedly installed on the installation platform. The bottom of the siphon tank is connected to the water storage tank through a suction pipe. A delivery pump is installed on the installation platform. The water suction pipe of the delivery pump is connected to the siphon tank. The delivery pump is equipped with a water outlet pipe to deliver high-pressure water. An exhaust pipe is installed at the top of the siphon tank. A liquid jet vacuum pump is installed between the water outlet pipe and the exhaust pipe. The liquid jet vacuum pump is equipped with a high-pressure water inlet pipe, a high-pressure water outlet pipe, and a vacuum pipe. The high-pressure water inlet pipe is connected to the water outlet pipe. The vacuum pipe is connected to the exhaust pipe. The high-pressure water outlet pipe is connected to the delivery pipe. A drain pipe is installed on the delivery pipe through a connecting pipe. The drain pipe extends to the water storage tank and is fixed to the installation platform by a support frame.

[0006] The liquid jet vacuum pump consists of two units, which are arranged side by side between the water outlet pipe and the exhaust pipe.

[0007] The liquid jet vacuum pump has the following structure: it includes a housing, inside which is a hollow sealed cavity. The high-pressure water inlet pipe is located at one end of the housing and communicates with the hollow sealed cavity. The high-pressure water outlet pipe and the vacuum pump pipe are located on both sides of the same end of the housing, and both extend into the hollow sealed cavity. The high-pressure water outlet pipe and the vacuum pump pipe are connected in the hollow sealed cavity. The diameter of the vacuum pump pipe is smaller than the diameter of the high-pressure water outlet pipe. The high-pressure water outlet pipe and the vacuum pump pipe are connected by at least two levels of annular stepped pipes. Each level of annular stepped pipe has an array of water inlet holes facing the high-pressure water outlet pipe.

[0008] The annular step has two stages. A primary water inlet is provided on the annular step near the vacuum tube, and a secondary water inlet is provided on the annular step near the high-pressure water outlet. A tertiary water inlet is arrayed on the pipe between the annular step with the secondary water inlet and the high-pressure water outlet.

[0009] A valve is installed on the exhaust pipe near the siphon tank.

[0010] A support rod is fixedly installed at the bottom of the installation platform, and an anti-slip pad is fixedly connected to the bottom of the support rod.

[0011] The high-pressure water jet driven siphon system anti-leakage vacuum device obtained by this invention has the following beneficial effects:

[0012] (1) A dual-path air extraction mechanism driven by high-pressure water jet is realized. The liquid jet vacuum pump is driven by the high-pressure water flow output by the delivery pump. The negative pressure is formed through the Venturi effect, so that the vacuum tube continuously extracts air from the siphon tank and prevents siphon interruption caused by air leakage. At the same time, the high-pressure water inlet pipe leads some high-pressure water back to the liquid jet vacuum pump to form a self-circulating power without the need for additional energy. The valve can be closed at any time to maintain the vacuum in the tank. The drain pipe and delivery pipe coordinate liquid discharge and high-pressure water delivery, thereby solving the problem of frequent pump stoppage due to air leakage in the traditional siphon system and achieving continuous and stable operation.

[0013] (2) The stability and reliability of the device have been further improved. The support frame firmly supports the drain pipe to ensure the structural stability under high water pressure conditions. The suction pipe connects the siphon tank and the water storage tank to automatically replenish the liquid to maintain the liquid seal conditions required for siphoning. The water storage tank serves as a buffer container to match the system flow requirements. The support rod and anti-slip pad enhance the device's anti-slip and anti-vibration capabilities. This not only solves the problem of operation interruption caused by air leakage or insufficient liquid level in traditional siphon systems, but also improves the system's environmental adaptability and maintenance convenience through modular design, thereby achieving long-term stable and efficient operation.

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example 1:

[0021] like Figures 1-5 As shown, this utility model discloses a high-pressure water jet driven siphon system anti-leakage vacuum device, including a water storage tank, an installation platform, and a siphon tank. The siphon tank is fixedly installed on the installation platform. The bottom of the siphon tank is connected to the water storage tank through a suction pipe. A delivery pump is installed on the installation platform. The water suction pipe of the delivery pump is connected to the siphon tank. The delivery pump is equipped with a water outlet pipe to deliver high-pressure water. An exhaust pipe is installed at the top of the siphon tank. A liquid jet vacuum pump is installed between the water outlet pipe and the exhaust pipe. The liquid jet vacuum pump is equipped with a high-pressure water inlet pipe, a high-pressure water outlet pipe, and a vacuum pipe. The high-pressure water inlet pipe is connected to the water outlet pipe. The vacuum pipe is connected to the exhaust pipe. The high-pressure water outlet pipe is connected to the delivery pipe. A drain pipe is installed on the delivery pipe through a connecting pipe. The drain pipe extends to the water storage tank and is fixed to the installation platform by a support frame.

[0022] In practical use, the siphon tank maintains a negative pressure state. The siphon tank and the water storage tank are connected via a suction pipe, so under the negative pressure, water from the storage tank is forced into the siphon tank. A delivery pump is installed on the mounting platform. The inlet of the delivery pump is connected to the lower end of the siphon tank via a suction pipe. The delivery pump draws water from the siphon tank and delivers it outwards through the outlet pipe, forming high-pressure water. This high-pressure water is divided into two streams in the outlet pipe: one stream is delivered to the work area, and the other stream enters the liquid jet vacuum pump through the high-pressure water inlet pipe. The liquid jet vacuum pump is connected to the vacuum pump pipe and the high-pressure water outlet pipe. The high-pressure water flows through the liquid jet vacuum pump and exits through the high-pressure water outlet pipe. During this process, a negative pressure is created at the vacuum pump pipe, which carries away air from the exhaust pipe, maintaining a negative pressure state inside the siphon tank. One end of the exhaust pipe is closed. High-pressure water from the liquid jet vacuum pump carries air from the siphon tank and discharges the water-air mixture through the delivery pipe, connecting pipe, and drain pipe to the storage tank for reuse.

[0023] In the above process, a high-pressure water-guided liquid jet vacuum pump is used to evacuate the siphon tank to maintain its vacuum level. Even if a small amount of air leakage occurs at the interface during long-term use of the siphon tank, the internal negative pressure can be kept stable, which solves the problem of frequent pump stoppage due to air leakage in the siphon system and realizes the continuous and stable operation of the system.

[0024] Two liquid jet vacuum pumps are used, arranged side by side between the water outlet pipe and the exhaust pipe. The two liquid jet vacuum pumps are connected in parallel, allowing them to operate simultaneously when evacuating the siphon tank, ensuring the stability of the vacuum process.

[0025] The liquid jet vacuum pump has the following structure: it includes a housing, inside which is a hollow sealed cavity. The high-pressure water inlet pipe is located at one end of the housing and communicates with the hollow sealed cavity. The high-pressure water outlet pipe and the vacuum pump pipe are located on both sides of the same end of the housing, and both extend into the hollow sealed cavity. The high-pressure water outlet pipe and the vacuum pump pipe are connected in the hollow sealed cavity. The diameter of the vacuum pump pipe is smaller than the diameter of the high-pressure water outlet pipe. The high-pressure water outlet pipe and the vacuum pump pipe are connected by at least two levels of annular stepped pipes. Each level of annular stepped pipe has an array of water inlet holes facing the high-pressure water outlet pipe.

[0026] The annular step has two stages. A primary water inlet is provided on the annular step near the vacuum tube, and a secondary water inlet is provided on the annular step near the high-pressure water outlet. A tertiary water inlet is arrayed on the pipe between the annular step with the secondary water inlet and the high-pressure water outlet.

[0027] In this embodiment, a two-stage annular step is used, with a primary and secondary water inlet on each stage. The number of primary and secondary water inlets is multiple, determined according to actual needs, and they are arranged in a ring. Both the primary and secondary water inlets are inclined towards the high-pressure water outlet pipe. When the high-pressure water flows through the hollow, sealed cavity of the shell through the primary and secondary water inlets, it is jetted towards the high-pressure water outlet pipe, creating a Venturi effect. The tertiary water inlet also generates the force to flow towards the high-pressure water outlet pipe, increasing the water flow rate. Based on the Venturi effect, the high-pressure water is rapidly ejected from the high-pressure water outlet pipe, creating a negative pressure zone at the vacuum pipe and the high-pressure water outlet pipe, thus generating negative pressure at the vacuum pipe and completing the vacuuming of the siphon tank.

[0028] A valve is installed on the exhaust pipe near one end of the siphon tank. In actual use, if the negative pressure inside the siphon tank is stable, the valve can be closed to establish a stable negative pressure within the siphon tank.

[0029] A support rod is fixedly installed at the bottom of the installation platform, and an anti-slip pad is fixedly connected to the bottom of the support rod. The installation platform is fixed by the support rod and the anti-slip pad is set at the bottom to increase the anti-slip performance of the bottom of the support rod, increase friction, and at the same time distribute the load to prevent the installation platform from shifting due to the impact of high-pressure water flow or vibration.

[0030] Practical application scenarios:

[0031] In the purification process of tap water, key operations such as filter backwashing, chemical dosing, or sludge discharge are often achieved through siphon systems. Traditional siphon systems often leak air due to aging pipe joints, seal failure, or liquid level fluctuations, requiring frequent pump shutdowns and manual priming, which seriously affects the continuous operation efficiency of water plants. Especially in large-scale water supply scenarios, even short-term shutdowns can lead to water pressure fluctuations or even water supply interruptions. The proposed solution, through a self-sustaining jet air extraction mechanism, can completely solve the air leakage problem of siphon systems and ensure the stable operation of key processes in tap water plants.

[0032] In the backwashing section of the water treatment plant's filter, this device is installed in the siphon operation area:

[0033] The installation platform is fixed to the concrete base by the anti-slip pads on the bottom support rods to ensure earthquake resistance and anti-slip properties.

[0034] The siphon tank is connected to the water storage tank below the filter drainage trough via a suction pipe, and the water storage tank is pre-filled with clean water;

[0035] The pump's suction pipe is inserted into the siphon tank, and the outlet pipe is split into two paths: one path is connected to the backwash pipe, and the other path is connected to the liquid jet vacuum pump through the high-pressure water inlet pipe.

[0036] The valve on the exhaust pipe is initially in the open position, and the vacuum tube is sealed and connected to the exhaust pipe.

[0037] Start the delivery pump, and the high-pressure water flow is split into two streams from the outlet pipe: one stream enters the backwash pipe to perform routine operations, and the other stream enters the liquid jet vacuum pump through the high-pressure water inlet pipe.

[0038] High-pressure water is accelerated and sprayed at the connection between the vacuum tube and the high-pressure water outlet tube in the liquid jet vacuum pump through the first-stage water inlet, the second-stage water inlet, and the third-stage water inlet. The negative pressure is formed at the connection through the Venturi effect, which in turn generates a negative pressure in the vacuum tube, driving the vacuum tube to continuously draw air from the siphon tank.

[0039] As the air inside the tank is extracted, a negative pressure is formed inside the siphon tank, and the clean water in the water storage tank is automatically drawn into the siphon tank through the suction pipe to maintain the liquid seal state.

[0040] Once the siphon effect is fully established, close the valve on the exhaust pipe to block the entry of external air. At this point, the liquid jet vacuum pump only needs to handle a small amount of infiltrated gas.

[0041] Leakage prevention guarantee: If the siphon tank leaks a small amount of air due to aging of the seals, the liquid jet vacuum pump will pump the air out in real time through the vacuum tube to ensure stable negative pressure inside the tank.

[0042] Liquid level balance: The water storage tank is automatically replenished through the suction pipe to prevent the siphon from being interrupted due to a drop in liquid level;

[0043] Vibration control: The support frame fixes the drainage pipe, and the support rod resists the impact of water flow to prevent pipe vibration from affecting the efficiency of the jet pump;

[0044] Emergency Operation: If maintenance is required, the valve can be manually opened to release the vacuum, and the power supply to the delivery pump can be cut off before safe disassembly.

[0045] Uninterrupted operation: Compared to traditional siphon systems that require multiple pump shutdowns for maintenance each day, this device can operate continuously for months without intervention;

[0046] Energy-efficient and high-performance: The jet vacuum pump is driven by the excess water pressure of the delivery pump, requiring no additional energy consumption;

[0047] Highly adaptable: Suitable for various siphon scenarios in factories, such as filter backwashing and sedimentation tank sludge removal, and poses no risk of water pollution.

[0048] Working Principle: When the device starts, the delivery pump draws liquid from the siphon tank through the suction pipe, pressurizes it, and outputs a high-pressure water stream from the outlet pipe. This high-pressure water stream is divided into two paths: one path performs conventional process operations (such as backwashing or sludge removal), and the other path enters the liquid jet vacuum pump through the high-pressure water inlet pipe. The liquid jet vacuum pump, as the core component, uses primary, secondary, and tertiary inlets to accelerate the high-pressure water stream, forming a high-speed jet at the vacuum pipe and the high-pressure water outlet pipe. According to the Venturi effect, the high-speed fluid generates a significant negative pressure zone in the narrow channel. This negative pressure drives the vacuum pipe to continuously draw air from the vent pipe at the top of the siphon tank. As air is continuously drawn out, a stable negative pressure environment is formed inside the siphon tank. At this time, the bottom suction pipe automatically replenishes liquid from the storage tank under the action of pressure difference, maintaining the liquid seal state inside the tank and ensuring uninterrupted siphoning. The device features valves that regulate the opening and closing of the exhaust pipe, shutting off after vacuum is established to isolate external air. A liquid jet vacuum pump continuously handles any trace amounts of gas that may seep in through sealed gaps. A rigid structural system consisting of a support frame and support rods ensures the stability of the high-pressure pipeline under intense water flow impact, preventing loosening of connections due to vibration. The entire workflow forms a closed-loop control: the delivery pump provides the power source, the liquid jet vacuum pump generates negative pressure, the siphon tank maintains the vacuum, the water tank automatically replenishes the liquid, and the system operates continuously. Each component achieves energy transfer and functional coupling through precise fluid path design. This device innovatively utilizes the high-pressure water flow from the process itself as the pumping power, eliminating the need for external vacuum equipment. It solves the problem of frequent interruptions caused by leakage in traditional siphon systems and significantly improves system reliability and energy efficiency through a self-sustaining mechanism, making it particularly suitable for industrial scenarios requiring long-term unattended operation.
