Description

Technical Field

[0001] This utility model relates to the field of fluid transport equipment technology, and in particular to a flexible tube dosing device. Background Technology

[0002] Currently, mechanical diaphragm pumps are a commonly used fluid transport device. They transport fluids by driving the diaphragm to reciprocate through mechanical transmission. Due to the frictional characteristics between the mechanical transmission and the diaphragm, the diaphragm's lifespan is severely affected, requiring regular diaphragm replacement, which increases maintenance costs and downtime. In addition to the diaphragm, each diaphragm pump needs to be equipped with a drive unit, valve body, and transmission components, resulting in a complex structure and high maintenance costs.

[0003] To address these issues, we developed a flexible tube dosing device. Utility Model Content

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Figures 1 to 5A flexible hose dosing device includes a dosing tank 20, which is sealed to at least one flexible hose 10 via an inlet pipe 311. The flexible hose 10 is connected to a vacuum pump 40 via a tee connector 34. The tee connector 34 is adjustablely connected to an outlet pipe 321 at its center. An inlet valve 31 is sealed to the center of the inlet pipe 311, and the inlet valve 31 is equipped with a first solenoid valve 310. The outlet pipe 321 is equipped with an outlet valve 32, and the outlet valve 32 is equipped with a second solenoid valve 320. The inlet pipe 311 is adjustablely connected to the dosing tank 20. Pump 40 is sealed to a suction pipe 401 and an exhaust pipe 402. The suction pipe 401 is adjustablely connected to a three-way connector 34. The suction pipe 401 is equipped with a vacuum valve 33, and the vacuum valve 33 is equipped with a third solenoid valve 330. Vacuum pump 40 includes a drive body 41 and a cavity 42. A timer 45 and a power switch 49 are located on the outer wall of the drive body 41. A pressure gauge 43 and a connector 46 are located on the outer wall of the cavity 42. The connector 46 has a conical structure and a barbed shank 461 on its outer wall. The barbed shank 461 and the suction pipe 401 are sealed together by clamps. When the power switch 49 is turned on, the PLC controller 470 controls the operation of each solenoid valve. When the pressure gauge reaches a certain scale and is held for a certain time, the air in the elastic hose 10 and the connecting pipe is purged. The connector 46 is sealed to the suction pipe 401. A control box 47 is located at the top of vacuum pump 40. The dosing tank 20 has an inlet 22 and an outlet 21 at its top. The inlet 22 replenishes the dosing tank 20 with the chemical solution. The feed pipe 311 is inserted and sealed to the outlet 21, and a filter element 312 is fixedly connected to its bottom end. The outer wall of the filter element 312 has evenly distributed filter mesh holes 3120 to prevent sedimentation of the chemical solution. The filter mesh holes can be circular, rectangular, or other shapes.

[0021] The first solenoid valve 310 is electrically connected to the control box 47. The control box 47 is electrically connected to the second solenoid valve 320. The third solenoid valve 330 is electrically connected to the control box 47. The control box 47 is equipped with a PLC controller 470, which is electrically connected to the first solenoid valve 310, the second solenoid valve 320, and the third solenoid valve 330 respectively. Multiple flexible hoses 10 can be connected in parallel between the vacuum pump 40 and the dosing tank 20 to reduce costs and improve delivery efficiency. Simultaneously, the flexible hoses and pipes operate under vacuum, eliminating the need for additional cleaning and saving manpower.

[0022] During operation, all valves are closed first, and the vacuum pump 40 runs, creating negative pressure in the pipeline. At this time, the vacuum valve 33 opens, creating negative pressure in the elastic hose 10, causing it to deform and compress. After a set time, the vacuum valve 33 is closed, and the feed valve 31 is opened. The elastic hose 10 returns to its original shape, and the generated negative pressure draws the liquid medicine from the dosing tank 20 into the elastic hose 10. The feed valve 31 is then closed, and the discharge valve 32 is opened. The liquid medicine flows through the tee connector 34 to the discharge pipeline and is discharged. After a set time, the discharge valve 32 is closed, and the vacuum valve 33 is reopened. This process is repeated to transport the liquid medicine.

[0023] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
