Description

Technical Field

[0001] The present disclosure relates to the technical field of circulating water detection, and in particular to a circulating water system. Background Art

[0002] A recirculating water system is a water treatment system commonly found in industrial, commercial, and residential settings. This system is designed to reuse water, reducing the need for fresh water, thereby conserving water and lowering operating costs.

[0003] When testing the pH (hydrogen ion concentration index) value of a circulating water system, a pH analyzer is generally connected directly to the circulating water system to continue testing the circulating water.

[0004] However, because the entire circulating water system is under pressure, the pH analyzer needs to be sealed and connected to the existing circulating water system. However, to obtain accurate readings, the pH analyzer needs to be regularly disassembled and calibrated with standard buffer solutions. A pH analyzer sealed to the circulating water system is difficult to disassemble and replace, and there is a risk of a loose seal and leaks in the circulating water system. Utility Model Content

[0005] A technical problem to be solved by the present disclosure is: how to conveniently replace a pH analyzer while avoiding problems of poor sealing and leakage of a circulating water system.

[0006] To solve the above technical problems, the present disclosure provides a circulating water system. It includes:

[0007] a water inlet pipe, wherein a first valve is provided on the water inlet pipe;

[0008] A container having an opening at the top thereof, wherein the container is connected to the water inlet pipe; and a pH value detection device, wherein the pH value detection device is arranged at the opening.

[0009] In some embodiments, the pH value detection device includes a detection portion and a display portion, the detection portion and the display portion are connected, the detection portion extends toward the bottom of the container, and the display portion faces a position away from the bottom of the container.

[0010] In some embodiments, a drain port is provided at the bottom of the container.

[0011] In some embodiments, the drain outlet is connected to a drain pipe, and a second valve is provided on the drain pipe.

[0012] In some embodiments, a scale is provided on the inner wall of the container, and the position of the scale is higher than the detection end of the detection part.

[0013] In some embodiments, further comprising:

[0014] Water collection tank, which is connected to the drainage pipe.

[0015] In some embodiments, a first quick-connect connector is provided at the water inlet end of the water inlet pipe.

[0016] In some embodiments, a second quick-connect connector is provided at the end of the drainage pipe.

[0020] The handle is arranged on the side wall of the container.

[0021] Through the above technical solution, the circulating water system provided by the present invention is connected to the container through an additional water inlet pipe. When testing is required, the water in the circulating system is introduced into the container by opening the first valve, and then the pH value is tested by the pH value detection device arranged at the top outlet of the container. In this way, the pH value detection device is not directly connected to the circulating water system, which eliminates the restriction that the pH value detection device must be sealed with the circulating water system, and facilitates the direct replacement of different types of pH detection devices at the opening, avoiding the problems of loose sealing and leakage of the circulating water system.

[0033] A recirculating water system is a water treatment system commonly found in industrial, commercial, and residential settings. This system is designed to reuse water, reducing the need for fresh water, thereby conserving water and lowering operating costs.

[0034] When testing the pH value of a circulating water system, the pH analyzer is generally connected directly to the circulating water system to continue testing the circulating water.

[0035] However, because the entire circulating water system is under a certain pressure, the pH analyzer needs to be sealed and connected to the existing circulating water system. However, to obtain accurate readings, the pH analyzer needs to be regularly disassembled and calibrated with standard buffer solutions. A pH analyzer sealed to the circulating water system is difficult to disassemble and replace, and there is a risk of a loose seal and leaks in the circulating water system.

[0036] In order to solve the above technical problems, the present disclosure proposes a method for conveniently replacing a pH analyzer and avoiding loose sealing and leakage of a circulating water system.

[0037] Example 1

[0038] like Figure 1 As shown, a circulating water system includes a water inlet pipe 1, a container 3 and a pH value detection device 4. A first valve 2 is provided on the water inlet pipe 1; an opening is provided on the top of the container 3, and the container 3 and the water inlet pipe 1 are connected; the pH value detection device 4 is provided at the opening.

[0039] The water inlet pipe 1 is a key pipe in the circulating water system, responsible for introducing water into the system's container 3. Specifically, the water inlet pipe 1 can be made of polyvinyl chloride (PVC), which is highly corrosion-resistant and relatively inexpensive. It is typically a straight pipe with various connectors at both ends for easy connection to other pipes or equipment. It is suitable for general water treatment systems, especially in applications where water quality requirements are low. The water inlet pipe 1 can also be made of stainless steel (such as 304 or 316L), which offers excellent corrosion resistance and strength. It can be welded or seamless, with wall thickness selected based on pressure rating. It is suitable for systems with high water quality requirements, such as in the food processing and pharmaceutical industries. The water inlet pipe 1 can also be made of copper pipe, which offers excellent thermal conductivity, pressure resistance, and corrosion resistance. It is typically constructed of rigid or flexible pipe, with connection methods including welding, threading, or crimping. It is suitable for applications requiring excellent thermal conductivity, such as heating systems. The water inlet pipe 1 can also be made of polyethylene (PE), more specifically, high-density polyethylene (HDPE) or low-density polyethylene (LDPE). The polyethylene water inlet pipe 1 has good flexibility and can be connected to the pipeline of the circulating water system by hot melting or electric melting, and is suitable for agricultural irrigation and urban water supply and drainage systems.

[0040] More specifically, a filter can be installed at the front end of the water inlet pipe 1 to remove impurities from the water. When used in cold regions, the pipe may need to be wrapped with insulation material. In cold climates, electric heating cables or other methods can be used to prevent the pipe from freezing. Flanges, threaded joints, quick connectors, etc. can be provided at both ends of the water inlet pipe 1 to connect different pipes or equipment. As long as the water inlet pipe 1 can introduce water from the original circulating water system into the container 3, there is no specific limitation on the structure and material of the water inlet pipe 1.

[0041] First valve 2 is a valve used to control the flow of water in water inlet pipe 1 in a circulating water system. Specifically, first valve 2 can be a ball valve, which has a spherical closing member with a hole drilled in it. When the valve is open, the hole in the ball aligns with the direction of the pipe, allowing fluid to pass through. When closed, it rotates 90 degrees so that the hole is perpendicular to the flow direction, preventing fluid from passing through. Ball valves offer excellent sealing performance, simple and quick operation, and easy maintenance. First valve 2 can also be a gate valve, which has a rising rod and a flat gate. When the gate is fully open, the flow channel is completely open and unobstructed. When closed, the gate descends to the bottom of the pipe, shutting off the flow. Gate valves have low flow resistance and are suitable for pipelines with high flow rates. First valve 2 can also be a butterfly valve, which has a central axis that passes through a butterfly disk located inside the pipe. The butterfly disk is opened or closed by rotating the central axis. Butterfly valves are compact, lightweight, and low-cost.

[0042] More specifically, the first valve 2 can also be a stop valve, which has a disc and a seat. The valve is opened by lifting the disc away from the seat, and closed by lifting the disc. This provides good throttling control and sealing performance. By configuring the first valve 2 as a stop valve, the flow rate of the incoming water can be controlled, which, in conjunction with the drain port 5, controls the water level in the container 3, ensuring that the pH detection device 4 can measure the pH value.

[0043] Container 3 is an important component of the circulating water system and is used to store and process water. Specifically, container 3 can be 304 or 316 stainless steel, which has good corrosion resistance; stainless steel container 3 can be in various shapes such as cylindrical, square or rectangular, and can be provided with reinforcing ribs to increase structural stability. Stainless steel container 3 is corrosion-resistant, easy to clean, and suitable for long-term water storage. Container 3 can also be made of plastic, such as polyethylene (PE), polypropylene (PP), polycarbonate (PC), etc. Plastic container 3 is usually injection molded or blow molded, and has various shapes, from simple barrels to complex multi-cavity structures.

[0044] The plastic container 3 is lightweight, relatively low in cost, and resistant to chemical corrosion. More specifically, the container 3 may also be a fiberglass container 3, such as fiberglass reinforced plastic, combined with a resin matrix material; the fiberglass container 3 can be made into various shapes and sizes, and generally has strong mechanical strength and corrosion resistance. The fiberglass container 3 is moderately heavy, corrosion-resistant, and suitable for outdoor installation. The container 3 may also be made of reinforced concrete. The concrete container 3 may be a large fixed container 3, which is generally used to build pools or reservoirs, and is durable and has a large capacity. The container 3 may be made of carbon steel, and the carbon steel container 3 may be a welded structure or integrally formed. The carbon steel container 3 has a lower cost and a higher strength.

[0045] More specifically, the container 3 may include a main body, a reinforcement structure, a connector, an inspection port and a base: the main body is the main part of the container 3, which is used to hold water. The reinforcement structure can improve the carrying capacity and stability of the container 3. For example, reinforcing ribs or support frames can be set inside and outside the wall of the container 3. The connector is used to connect the water inlet pipe 1, the water outlet pipe and the interfaces of other equipment. A larger container 3 can be provided with an inspection port to facilitate internal cleaning and maintenance. The base is provided at the bottom of the main body to support the entire container 3 and ensure stable placement. As long as the container 3 can accommodate water entering from the water inlet pipe 1 and enable the pH value detection device 4 to measure the pH value, the material and structure of the container 3 are not specifically limited. A filtering device, such as a filter or a screen, can also be provided at the drain outlet 5 of the container 3 to remove suspended matter.

[0046] More specifically, the opening at the top of container 3 is a critical design element in the circulating water system, impacting not only the ease of operation but also maintenance and safety. The opening can be a cover-type opening, a flange-type opening, or a grid- or grille-type opening. A flange-type opening has a flanged edge that can be connected to a matching flange cover or other flange connector. Flange-type openings offer excellent sealing and facilitate removal and installation. The pH detection device 4 can be mounted on the flange at the opening to secure its position and ensure accurate measurement results. A grid or grille can be installed at the opening to ensure ventilation and prevent the entry of foreign objects. A grid- or grille-type opening offers good air permeability and provides a degree of protection, preventing large objects from entering container 3. More specifically, the opening of container 3 can be circular, square, rectangular, or any other shape. A circular opening is the most common and is easier to manufacture. A square or rectangular opening provides a larger opening area, facilitating the entry and exit of the pH detection device 4. The shape of the opening can also be customized based on the shape of the detection portion of the pH detection device 4 to facilitate installation. Reinforcement ribs may be provided around the opening to increase the structural strength of the opening and prevent deformation due to excessive water pressure.

[0047] The pH value detection device 4 is an important device for monitoring the acidity and alkalinity of water in a circulating water system. The pH value detection device 4 usually works based on the glass electrode method. This electrode includes an internal reference electrode and an external measuring electrode. The measuring electrode is made of a glass membrane, and when it is immersed in a solution, it forms a potential difference proportional to the pH value of the solution. This potential difference is transmitted to the pH meter through the electrode lead, and the pH meter converts the electrical signal into a pH value for display. Specifically, the pH value detection device 4 can be a pH meter, a pH analyzer, and the like. The pH value detection device 4 can be connected to a transmission module unit, and after detection, the pH value data can be transmitted to a DCS (distributed control system) for viewing real-time data.

[0048] As long as the pH value detection device 4 can detect the pH value of the circulating water in the container 3 , there is no specific limitation on the specific structure and shape of the pH detection device.

[0049] During use, the valve is opened to introduce water from the circulating water system into container 3, whereupon the pH value is measured by pH detection device 4. When container 3 is full, the water can overflow from the opening of container 3. Alternatively, an overflow port can be provided near the opening of container 3 to allow the water in container 3 to flow out. The overflow port is positioned above the detection portion of pH detection device 4 to ensure contact with the detection portion. The overflowed water can be collected and reused.

[0050] Through the above technical solution, the circulating water system provided by the present invention is connected to the container 3 by an additional lead-out pipe in the original circulating water system. When testing is required, the water in the circulating system is introduced into the container 3 by opening the first valve 2, and then the pH value thereof is tested by the pH value detection device 4 arranged at the top outlet of the container 3. In this way, the pH value detection device 4 is not directly connected to the circulating water system, which eliminates the restriction that the pH value detection device 4 must be sealed with the circulating water system, and facilitates the direct replacement of different types of pH detection devices at the opening, thereby avoiding loose sealing and leakage of the circulating water system.

[0051] In some embodiments, the pH value detection device 4 includes a detection portion and a display portion, which are connected. The detection portion extends toward the bottom of the container 3 , and the display portion faces a position away from the bottom of the container 3 .

[0052] The detection part is the part of the pH value detection device 4 that is responsible for collecting the pH value signal of the water sample. Specifically, the detection part may include an electrode, a cable, and an extension rod; it may be a glass electrode for sensing the pH value in the water sample. The electrode head may be provided with a protective cover to prevent damage. The cable is used to connect the electrode to the display part to transmit the measurement signal. In order to enable the electrode to penetrate deep into the bottom of the container 3, the detection part may be equipped with an extension rod so that the electrode can contact the water sample at the bottom of the container 3 to ensure the representativeness of the measurement. As long as the detection part can collect the pH value signal of the water sample, the specific structure of the detection part is not limited.

[0053] The display unit is the part of the pH value detection device 4 that is responsible for displaying the measurement results. Specifically, the display unit can be a pH meter. More specifically, the display unit can include a display screen, and the display screen can be an LCD (liquid crystal display) or LED (light emitting diode) screen for displaying the measurement results, with the display screen facing a position away from the bottom of the container 3. The display unit can also include control buttons for operating the various functions of the pH meter, such as calibration, setting parameters, etc. The display unit can also include a power interface, and the power supply mode can be battery-powered or externally powered. The display unit can also include a communication interface, and the communication interface can include interfaces such as RS232, RS485 or USB for data transmission or communication with external devices. As long as the display unit can display the pH value detection result, the specific structure of the display unit is not limited.

[0054] By extending the detection portion toward the bottom of the container 3 , the detection portion can more easily contact the water in the container 3 ; and by arranging the display portion at a position facing away from the bottom of the container 3 , the operator can more conveniently read the pH value measurement result.

[0055] In some embodiments, a drain outlet 5 is provided at the bottom of the container 3. Specifically, the drain outlet 5 can be located at the center of the bottom of the container 3, so as to ensure that as much water as possible in the container 3 is drained; the drain outlet 5 can also be provided on a side of the bottom to facilitate the connection of the drainage pipe. The drain outlet 5 can be circular, which is convenient for manufacturing and connection. The drain outlet 5 can also be square or rectangular, which can drain a larger area. The drain outlet 5 is provided at the bottom of the container 3, and can cooperate with the first valve 2 so that the flow rate of the first valve 2 is the same as the flow rate of the drain outlet 5, ensuring that the liquid level of the water in the container 3 remains unchanged, avoiding water overflow and wasting water resources, and also avoiding water flooding the display part of the pH detection device 4, thereby damaging the instrument. In addition, the drain outlet 5 is provided at the bottom of the container 3 to conveniently discharge the water in the container 3, which is convenient for cleaning, maintenance and emergency discharge of the system.

[0056] In some embodiments, drain outlet 5 is connected to a drainage pipe equipped with a second valve. The drainage pipe can have the same structure and type as the inlet pipe 1, and the second valve can also have the same structure and type as the first valve 2. The second valve can control the flow rate in the drainage pipe, ensuring that the flow rates of the inlet pipe 1 and the outlet pipe are the same. The second valve coordinates with the first valve 2 to control the flow rate of the inlet pipe 1, thereby reducing the flow rate while maintaining the water level in the container 3, thereby reducing water waste.

[0057] In some embodiments, the inner wall of the container 3 is provided with a scale, and the scale is located higher than the detection end of the detection unit. By setting the scale on the inner wall of the container 3, the water level to be reached can be marked. The scale is set at a position higher than the detection end of the detection unit to ensure that the detection end can contact the water for detection. Specifically, during use, the flow rate of the first valve 2 can be controlled to be greater than the flow rate of the drain outlet 5 or the drain pipe, so that the water level in the container 3 rises. When the water level rises to the scale line of the container 3, the flow rate of the first valve 2 can be reduced to the same as the flow rate of the drain outlet 5 or the drain pipe, so that the water level remains on the scale line. Then, by simultaneously reducing the flow rate of the first valve 2 and the second valve, the water level can be maintained while reducing water waste.

[0058] In some embodiments, the circulating water system further includes a water collection tank connected to a drainage pipe. The water collection tank can be used to collect water from the container 3 for reuse, thereby avoiding wasting water resources. For example, a water pump can be provided in the water collection tank, connected to a water pipe in the circulating water system, thereby pumping the water in the water collection tank back into the circulating water system, thereby reusing water resources.

[0059] In some embodiments, a first quick-connect connector is provided at the water inlet end of the water inlet pipe 1. The first quick-connect connector consists of two parts: a male connector (plug) and a female connector (socket). When the male connector is inserted into the female connector, the internal snap-fit mechanism automatically locks, and the sealing ring ensures that the connection is leak-proof. When disconnecting, simply press the release button or lever on the connector to easily separate it. The provision of the first quick-connect connector at the water inlet end of the water inlet pipe 1 allows for quick and convenient connection and disconnection of the piping system, and the connection and disconnection operations can be completed without the use of tools, thereby improving the portability of the container 3 and the detection device.

[0060] In some embodiments, a second quick-connect connector is provided at the end of the drainage pipe. The second quick-connect connector is also composed of two parts: a male connector (plug) and a female connector (socket). When the male connector is inserted into the female connector, the internal snap-fit mechanism will automatically lock, and the sealing ring will ensure that the connection is leak-proof. When disconnecting, just press the release button or lever on the connector to easily separate it. The second quick-connect connector provided at the end of the drainage pipe can quickly and conveniently connect and disconnect the water collection tank, and the connection and disconnection operations can be completed without the use of tools, thereby further improving the portability of the container 3 and the detection device.

[0061] In some embodiments, the circulating water system further includes a cover that covers the opening and has a through-hole at its center. The pH detection device 4 is disposed within the through-hole. The cover's structure can be adapted to the shape of the opening, completely obscuring the through-hole and preventing objects from falling into and contaminating the circulation pool. The through-hole's shape can also be adapted to the structure of the detection unit, allowing the detection unit to extend into the interior of the container 3 while the display unit remains on the cover for easy reading.

[0062] In some embodiments, the circulating water system further comprises a handle disposed on the side wall of the container 3. By disposing the handle on the side wall of the container 3, when the container 3 is small in size, the container 3 can be conveniently and directly lifted, thereby further improving portability.

[0063] Thus far, various embodiments of the present disclosure have been described in detail. To avoid obscuring the concept of the present disclosure, some details known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.

[0064] Although some specific embodiments of the present disclosure have been described in detail through examples, those skilled in the art will understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present disclosure. Those skilled in the art will understand that the above embodiments may be modified or some technical features may be replaced with equivalents without departing from the scope and spirit of the present disclosure.
