Description

Technical Field

[0001] This invention relates to the field of diaphragm pump technology, and in particular to a diaphragm pump that switches between high and low suction and high and low head, and its method of use. Background Technology

[0002] A diaphragm pump is a common type of pump, also known as a pneumatic diaphragm pump. It uses a flexible diaphragm that reciprocates inside the pump to compress and release fluids. Diaphragm pumps are widely used in industries such as chemical, food, water treatment, and pharmaceuticals, and can transport various corrosive liquids, liquids containing solid particles, and various gas-liquid mixtures.

[0003] However, its suction and head are constant. In theory, as long as the suction and head are high, it can adapt to various application scenarios. However, diaphragm pumps with high suction and high head also require a lot of power and consume a lot of energy. They cannot be arbitrarily matched according to the suction and head required by the scenario.

[0004] Therefore, a diaphragm pump with high and low suction and high and low head switching, and its usage method are proposed to solve or alleviate the above problems. Summary of the Invention

A one-way valve is provided in the lower near vertical pipe, the lower far vertical pipe, the upper near vertical pipe, and the upper far vertical pipe. A one-way valve is provided in the outlet pipe. It also includes an air pump, a first wire feeding module, a second wire feeding module, and a control circuit. The other two openings of the four-way pipe penetrate the cylinder to form an air inlet and an air outlet. The air pump is connected to the air inlet. The control circuit includes a controller, a distance measuring module, a viscosity module, and an opening / closing module coupled thereto. The controller is coupled to the air pump, the first wire feeding module, and the second wire feeding module. The movable ends of the first wire feeding module and the second wire feeding module are respectively fixedly connected to a suction head and a nozzle. Flexible hoses can be connected between the suction head and the inlet, and between the nozzle and the outlet. The distance measuring module detects the displacement distance of the suction head and the nozzle. The viscosity module detects the viscosity of the pumped liquid. The opening / closing module controls the independent opening and closing of the four openings of the four-way pipe. The controller controls the start and stop of the air pump and the opening and closing of the opening / closing module based on the feedback information from the distance measuring module and the viscosity module.

[0007] Preferably, the opening and closing module includes a miniature solenoid valve one, a miniature solenoid valve two, a miniature solenoid valve three, and a miniature solenoid valve four coupled to the controller. The miniature solenoid valve one, miniature solenoid valve two, miniature solenoid valve three, and miniature solenoid valve four are all located in the cylinder body and are respectively connected to the four pipes of the four-way pipe to control their opening and closing.

[0008] Preferably, the first wire feeding module includes a frame, a servo motor coupled to and fixedly connected to the controller on the frame, a take-up reel fixedly connected to the output shaft of the servo motor, and a connecting wire wound on the take-up reel and fixedly connected to the nozzle. The second wire feeding module includes a frame, a servo motor coupled to and fixedly connected to the controller on the frame, a take-up reel fixedly connected to the output shaft of the servo motor, and a connecting wire wound on the take-up reel and fixedly connected to the nozzle. Metal blocks are fixedly connected to both the take-up reel and the take-up reel.

[0009] Preferably, the ranging module includes a distance sensor, a Hall sensor one, and a Hall sensor two fixedly connected to the cylinder block. The distance sensor is coupled to the controller. The Hall sensor one and the Hall sensor two are fixedly connected to the frame one and the frame two, respectively, and both are positioned facing the disk surface where the metal block is located.

[0010] Preferably, the ranging module further includes a wireless generator fixedly connected to the nozzle, and a wireless receiver one and a wireless receiver two connected to it in communication. The wireless receiver one and the wireless receiver two are respectively fixedly connected to the top and bottom of the cylinder.

[0011] Preferably, the viscosity module includes a viscosity sensor coupled to the controller, and the detection end of the viscosity sensor extends into the inlet pipe.

[0014] Preferably, the air outlet is connected to a silencer.

[0015] This invention also provides a method of using a diaphragm pump that switches between high and low suction power and high and low head. The method includes the following steps: Step 1: After placing the entire diaphragm pump, manually determine whether the distance between it and the liquid surface can be directly detected by the distance sensor. If so, use the distance sensor to detect it. If not, input the control information to the controller through the touch screen, so that the controller controls the wire feeding module to feed the wire until the suction head reaches the liquid surface. Then install a hose with a length greater than the distance between the suction head and the inlet. Step 2: Input control information for the controller via the touch screen, and instruct the controller to control the second wire feeding module to feed the wire until the nozzle can be connected to the container. Then install a hose with a length greater than 0.5m from the nozzle to the outlet. Step 3: The controller detects the vertical distance between the nozzle and the suction head based on the distance measuring module, determines the air pump's blowing mode, and starts working. Step 4: During the operation of the air pump, as the liquid level drops, the line feeding module feeds the line in real time and sends the information back to the controller. The controller detects the vertical distance of the suction head based on the distance measuring module and switches the air pump's blowing mode. The air pump has two blowing modes: a suction mode and a head mode. The suction mode includes low suction, medium suction, and high suction. The head mode includes low head, medium head, and high head. In the low suction mode, the diaphragm closer to the inlet is drawn first, followed by the diaphragm farther from the inlet. In the medium suction mode, the diaphragm farther from the inlet is drawn first, followed by the diaphragm closer to the inlet. In the high suction mode, both diaphragms are drawn simultaneously. In the low head mode, the diaphragm closer to the inlet is squeezed first, followed by the diaphragm farther from the inlet. In the medium head mode, the diaphragm farther from the inlet is squeezed first, followed by the diaphragm closer to the inlet. In the high head mode, both diaphragms are squeezed simultaneously.

[0016] The present invention has the following beneficial effects: This invention, through its ingeniously designed components and modules, enables fully automated detection of the vertical distance from the liquid surface to the pump inlet, and the distance from the pump outlet to the target container. Based on these detection results, the system can accurately calculate in real time the required suction force between the liquid surface and the pump inlet, and the required suction path length between the pump outlet and the target container, i.e., the head. This intelligent calculation not only ensures adaptability to liquid surface conditions during pump operation but also allows for dynamic adjustments based on real-time conditions, automatically selecting optimal operating parameters to reduce overall energy consumption. This improves the diaphragm pump's energy efficiency ratio under various operating conditions, reduces power consumption, and extends its service life. Through advanced sensor and control technology, this invention ensures high efficiency and accuracy in diaphragm pump operation, providing an energy-saving and high-performance solution for modern pump technology.

The control circuit includes a controller 6, which is a single-chip microcomputer, a distance measuring module, a viscosity module, an opening and closing module coupled to it, and a display 131, which is a touch screen coupled to the controller 6. The controller 6 is coupled to the air pump 14, the wire feeding module one, and the wire feeding module two. The movable ends of the wire feeding module one and the wire feeding module two are respectively fixedly connected to a suction head and a nozzle. A hose can be connected between the suction head and the inlet 21 and between the nozzle and the outlet 51. The distance measuring module detects the displacement distance of the suction head and the nozzle. The viscosity module detects the viscosity of the sucked liquid. The opening and closing module controls the four openings of the four-way pipe to open and close independently. The controller 6 controls the start and stop of the air pump 14 and the opening and closing of the opening and closing module according to the feedback information from the distance measuring module and the viscosity module.

[0022] The opening and closing module includes miniature solenoid valve 1 71, miniature solenoid valve 2 72, miniature solenoid valve 3 73, and miniature solenoid valve 4 74 coupled to controller 6. Miniature solenoid valve 1 71, miniature solenoid valve 2 72, miniature solenoid valve 3 73, and miniature solenoid valve 4 74 are all located inside cylinder 1 and are respectively connected to the four pipes of the four-way pipe to control their opening and closing.

[0023] The first wire feeding module includes a frame, a servo motor 1211 coupled to and fixedly connected to the controller 6 on the frame, a take-up reel fixedly connected to the output shaft of the servo motor 1211, and a connecting wire wound on the take-up reel and fixedly connected to the nozzle.

[0025] The viscosity module includes a viscosity sensor 9 coupled to the controller 6, with the detection end of the viscosity sensor 9 extending into the inlet pipe 2.

[0026] This invention also provides a method of using a diaphragm pump that switches between high and low suction power and high and low head. The method includes the following steps: Step 1: After placing the entire diaphragm pump, manually determine whether the distance between it and the liquid surface can be directly detected by the distance sensor 8. If so, use the distance touch sensor to detect it. If not, input the control information to the controller 6 through the touch screen, so that the controller 6 controls the wire feeding module to feed the wire until the suction head reaches the liquid surface position. Then install a hose with a length greater than the distance between the suction head and the inlet 21. Step 2: Input control information for controller 6 via touch screen, so that controller 6 controls the wire feeding module 2 to feed the wire until the nozzle can be connected to the container. Then install a hose with a length greater than 0.5m from the nozzle to the outlet 51. Step 3: The controller 6 detects the vertical distance between the nozzle and the suction head based on the distance measuring module, determines the air pump 14's blowing mode, and starts working. Step 4: During the operation of air pump 14, as the liquid level drops, the line feeding module feeds the line in real time and sends the information back to controller 6. Controller 6 detects the vertical distance of the suction head based on the distance measuring module and switches the air blowing mode of air pump 14. The air pump 14 has two blowing modes: suction mode and head mode. The suction mode includes low suction, medium suction, and high suction. The head mode includes low head, medium head, and high head. In the low suction mode, the diaphragm closer to the inlet 21 is drawn first, and the diaphragm farther from the inlet 21 is drawn later. In the medium suction mode, the diaphragm farther from the inlet 21 is drawn first, and the diaphragm closer to the inlet 21 is drawn later. In the high suction mode, both diaphragms are drawn together. In the low head mode, the diaphragm closer to the inlet 21 is squeezed first, and the diaphragm farther from the inlet 21 is squeezed later. In the medium head mode, the diaphragm farther from the inlet 21 is squeezed first, and the diaphragm closer to the inlet 21 is squeezed later. In the high head mode, both diaphragms are squeezed together.

[0027] Through the above methods, this diaphragm pump adopts an intelligent design, featuring multiple modular components that automatically detect the vertical distance from the liquid surface to inlet 21 and the distance from outlet 51 to the container. These high-precision sensors are integrated into the pump system, monitoring and calculating the required suction force and pressure output in real time to ensure that the liquid can smoothly reach the pump inlet 21 from the liquid surface and be effectively delivered to the container connected to outlet 51.

[0028] Through this intelligent operation, the diaphragm pump can accurately determine the required suction force to overcome the height difference between the liquid surface and the inlet 21 under specific pumping conditions, and calculate the optimal head required between the outlet 51 and the container. It continuously adjusts the pump's operating status to ensure optimal pumping efficiency while saving energy. This means that the pump can automatically adjust to match the actual situation regardless of changes in the operating environment.

[0029] Furthermore, the intelligent control system of this diaphragm pump not only reduces energy consumption and operating costs, but also prevents unnecessary wear and potential equipment failures, thereby extending the equipment's service life. Its flexibility and adaptability make it an ideal suction device that maintains high efficiency and energy savings under various operating conditions.

[0030] Therefore, the advanced control system of this diaphragm pump gives it a unique advantage in dynamically handling complex pumping tasks, making it crucial for liquid handling. It can automatically adjust the pumping force and head as needed, and further reduce power consumption. This design reflects the latest development trends in intelligent and energy-saving diaphragm pumps, providing a groundbreaking and highly efficient solution for diaphragm pump applications.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
