Description

Technical Field

[0001] This utility model relates to the field of dosing machine technology, and in particular to a digital metering pump anti-clogging damping tube device. Background Technology

[0002] In the field of dosing equipment technology, traditional digital metering pump systems (electro-differential dosing machines) often become clogged when conveying liquids containing impurities due to the accumulation of deposits at pipe bends, valves, and pump inlets and outlets. This affects the continuity and stability of drug dosing and may even cause the entire dosing system to be shut down for maintenance.

[0003] Existing technologies typically rely on manual inspections and flushing, which are not only inefficient but also costly to maintain. Furthermore, traditional pipeline designs are often flawed, creating dead zones for sedimentation, while water hammer can damage pumps and piping systems, affecting the long-term stable operation of the equipment.

[0004] Therefore, there is an urgent need for an anti-clogging damping pipe device that can automatically detect blockages, intelligently switch flushing modes, and optimize pipeline structure to improve the reliability and automation level of the dosing system. Summary of the Invention

[0005] The main objective of this invention is to overcome the shortcomings of existing technologies and provide a digital metering pump anti-clogging damping tube device. Through structural innovation and intelligent control, it solves the problems of easy clogging and difficult maintenance in traditional dosing systems, making it suitable for high-precision, high-impurity environments for chemical dosing.

[0006] The technical solution adopted by this utility model to achieve its technical objective is: a digital metering pump anti-clogging damping tube device, including a bracket and a dosing metering pump installed on the bracket. The bracket serves as a basic support structure, and the dosing metering pump is fixedly installed to form the main frame of the device.

[0007] The inlet of the dosing metering pump is connected to a backwash inlet pipe and a liquid inlet pipe, and the outlet is connected to a drain pipe and a damping pipe. The damping tube is connected to an inclined tube, and the inclined tube is equipped with a backwash water outlet pipe and a medicine outlet pipe; The inlet pipe and the damping pipe are respectively equipped with a first damping tank and a second damping tank; the first damping tank and the second damping tank are connected in series on the inlet pipe and the damping pipe to buffer pressure fluctuations, absorb water hammer effects, and protect the pipeline and pump body.

[0008] A pressure sensor is installed between the inlet and outlet of the dosing metering pump. The pressure sensor is connected to the controller and is connected across the inlet and outlet of the dosing metering pump to monitor the pressure in real time. It triggers the controller to switch the working mode to normal dosing / rinsing / residual liquid discharge and is linked to the controller through an electrical signal.

[0009] Preferably, the angle between the inclined tube and the damping tube is 45 degrees. The 45-degree angle balances the sewage discharge efficiency and the structural compactness, avoids dead corners where impurities accumulate, and facilitates installation.

[0010] Preferably, a pressure gauge is installed on the inclined tube, which provides local pressure visualization monitoring to assist in verifying the system's operating status or for manual calibration.

[0011] Preferably, the inlet pipe, outlet pipe, backwash inlet pipe, backwash outlet pipe, and medicine outlet pipe are all equipped with electric valves; the pipeline switching is achieved by electric control opening and closing, for example, closing the inlet pipe and opening the backwash pipeline to start automatic flushing.

[0012] Preferably, the electric valve is an electromagnetically driven or electrically actuated mechanism. The electromagnetic or electric actuator of the electric valve's drive mechanism is mechanically connected to the valve body and interacts with the controller via a cable.

[0013] Preferably, the controller controls the opening or closing of the electric valves based on the detection signal from the pressure sensor. The controller receives the electrical signal from the pressure sensor and outputs control signals to each electric valve through logic circuits or programming instructions.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This digital metering pump anti-clogging damping pipe device can achieve automated anti-clogging control. It monitors pipeline pressure in real time through pressure sensors and automatically switches electric valves with the controller to achieve fully automated operation of clogging warning, residual liquid discharge and backwashing process, significantly reducing manual intervention.

[0015] The anti-clogging damping tube device of this digital metering pump features a highly efficient anti-deposition design. The inclined tube and damping tube are connected at an angle to optimize the fluid path and prevent impurities from accumulating. Together with the first damping tank and the second damping tank, it effectively suppresses the water hammer effect and extends the equipment's lifespan.

[0016] This digital metering pump anti-clogging damping pipe device has a multi-functional pipeline integration function. By separating the backwash water inlet pipe, the drain pipe and the chemical outlet pipe, it can quickly switch between the functions of adding chemicals, draining and backwashing, and improve the system's adaptability to complex working conditions.

[0017] This digital metering pump anti-clogging damping tube device significantly improves safety and stability. The pressure gauge provides real-time pressure monitoring, and the electric valve's electromagnetic or electric drive ensures precise control. The entire device can still operate stably under high pressure or impurity environments. Attached Figure Description

[0025] Please see Figures 1-2 A digital metering pump anti-clogging damping pipe device includes a bracket 1 and a dosing metering pump 2 fixedly installed on the bracket 1. The dosing metering pump 2 is equipped with a pressure sensor 15 for electrical connection. The pressure sensor 15 is fixed between the inlet and outlet of the dosing metering pump 2 and is used to monitor the liquid pressure in the pipeline. When the pipeline pressure is higher than the set value, the controller sends a control command to activate the electric valve to form a flushing circuit and realize automatic flushing.

[0026] The inlet of the dosing metering pump 2 is fixedly connected to the backwash inlet pipe 5 and the liquid inlet pipe 7 through the pump inlet pipe 3, and the outlet of the dosing metering pump 2 is fixedly connected to the drain pipe 6 and the damping pipe 9 through the pump outlet pipe 4.

[0027] A diagonal pipe 10 is fixedly connected to one side of the damping pipe 9. A backwash water outlet pipe 11, a medicine outlet pipe 12, and a pressure gauge 13 are fixedly connected to the diagonal pipe 10.

[0028] The backwash inlet pipe 5, drain pipe 6, inlet pipe 7, damping pipe 9, inclined pipe 10, backwash outlet pipe 11, chemical outlet pipe 12, and pressure gauge 13 can be fixedly installed on the bracket 1 as needed. Electric valves are fixedly installed in the pipelines of the backwash inlet pipe 5, drain pipe 6, inlet pipe 7, damping pipe 9, backwash outlet pipe 11, chemical outlet pipe 12, and pressure gauge 13. These electric valves are controlled by a controller to open or close. The pressure gauge 13 is used to display the liquid pressure inside the pipeline.

[0029] Furthermore, in this embodiment, a first damping tank 8 is fixedly installed on the inlet pipe 7, and a second damping tank 14 is fixedly installed on the damping pipe 9. The installation of the first damping tank 8 and the second damping tank 14 can prevent water hammer during the operation of the entire device.

[0030] Furthermore, in this embodiment, the angle of inclination between the damping tube 9 and the inclined tube 10 at the connection point is 45 degrees. Setting the angle too large is not conducive to installation, and setting it too small is not conducive to sewage discharge and is prone to accumulation. A moderate angle of 45 degrees is chosen. The damping tube 9 can be set vertically downward, while one end of the inclined tube 10 is inclined at 45 degrees and fixedly connected to one side of the damping tube 9.

[0031] Specifically, during use, when the digital metering pump anti-clogging damping tube device is operating normally, the electric valves on the backwash inlet pipe 5, drain pipe 6, and backwash outlet pipe 11 are all closed, the dosing metering pump 2 is turned on, and the liquid is connected through the inlet pipe 7. The liquid enters the pump inlet pipe 3 through the inlet pipe 7, and is then transported through the dosing metering pump 2 and the pump outlet pipe 4 to the damping tube 9, the inclined tube 10, and the liquid outlet pipe 12, and is discharged through the liquid outlet pipe 12.

[0032] When the anti-clogging damping tube device of the digital metering pump is blocked, the pressure sensor 15 reaches the specified value, the dosing metering pump 2 is shut down, and the electric valves on the backwash water inlet pipe 5, liquid inlet pipe 7, backwash water outlet pipe 11 and liquid outlet pipe 12 are all closed by the electronic control, while the electric valve on the drain pipe 6 is opened to automatically discharge the residual liquid in the device.

[0033] When the anti-clogging damping tube device of the digital metering pump becomes clogged and backwashing is required, the electric valves on the drain pipe 6, inlet pipe 7, and chemical outlet pipe 12 are all closed by the electronic control system, while the electric valves on the backwash inlet pipe 5 and backwash outlet pipe 11 are opened. The dosing metering pump 2 is turned on and connected to the water source through the backwash inlet pipe 5. The water source enters the pump inlet pipe 3 through the backwash inlet pipe 5 and is then transported to the damping tube 9, inclined pipe 10, and backwash outlet pipe 11 through the dosing metering pump 2 and pump outlet pipe 4. The device is then backwashed by the water source through the backwash outlet pipe 11.

[0034] It is important to note that the controller used in this device employs an existing electronically controlled electric valve system, which will not be described in detail here.

[0035] The working principle and specific usage process of the anti-clogging damping tube device for the digital metering pump are as follows: The pressure sensor 15 monitors the liquid pressure in the pipeline in real time. When the pressure exceeds the set value, the controller automatically shuts off the dosing metering pump 2 and controls the electric valve to switch the pipeline, forming a flushing circuit. During normal operation, the liquid medicine is output from the liquid medicine outlet pipe 12 through the inlet pipe 7, the first damping tank 8, the metering pump 2 and the damping pipe 9; when blocked, the inlet pipe is closed and the drain pipe 6 is opened to discharge the residual liquid medicine; during backwashing, the external water source is switched to flow in from the backwash water inlet pipe 5, and after passing through the metering pump 2, the damping pipe 9 and the inclined pipe 10, it is discharged from the backwash water outlet pipe 11 to achieve automatic unblocking.

[0036] The 45-degree inclined pipe 10 and the second damping tank 14 installed in the device optimize the sewage discharge effect and suppress the water hammer effect, respectively. The electric valves of each pipeline are coordinated by the electric control system to complete the switching of working states.

[0037] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural, procedural, or functional transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
