A typical pneumatic water pump consists of a tank, air delivery components, water pipes, and a controller. By pumping air, they control the air pressure within the tank to extract water, reducing the risk of pump blockage and damage. However, during actual construction, particulate matter from the mud collected during pumping often settles inside the pneumatic pump, requiring regular cleaning to ensure effective suction, which reduces construction efficiency.

Furthermore, the aeration part will continue to blow air into the liquid to accelerate the combination of particles in the liquid and the medicine for sedimentation, so that the liquid pumped by the pneumatic pump is relatively clear, reducing the possibility of particles depositing inside the pneumatic pump, extending the maintenance cycle of the pneumatic pump, and thus extending the cycle service life of the pneumatic pump.

[0023] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Reference Figure 1 A pneumatic pump with a protective device 2 includes a pump body 1 and a protective device 2. The protective device 2 is arranged on the pump body 1 and is supplied with air by the pump body 1. The protective device 2 includes an air flotation component and a filter component. The air flotation component and the filter component are respectively driven by the air supply of the pump body 1.

[0025] The flotation assembly includes a float 21 and an air supply unit. The float 21 is connected to the air supply unit, the other end of which is connected to the pump body 1. The filter assembly and the air supply unit are connected via a branch pipe 22. The air supply unit 22 can be a pipe 22 with a valve. The filter assembly includes an aeration unit 24 and a dosing unit 23. Air is supplied to the aeration unit 24 and the dosing unit 23 by the branch pipe 22. The dosing unit 23 and the aeration unit 24 are positioned below the liquid surface. During the pumping process, an air source is used to simultaneously supply air to the aeration unit 24 and the dosing unit 23. The gas pressure causes the agent stored in the dosing unit 23 to be sprayed into the liquid, thereby accelerating the sedimentation of solid particles in the liquid. Furthermore, the aeration unit 24 continuously blows air into the liquid, accelerating the sedimentation of particles in the liquid by combining with the agent. This results in relatively clear liquid pumped by the pneumatic pump, reduces the possibility of particles depositing inside the pneumatic pump, and extends the maintenance cycle of the pneumatic pump, thereby extending the cycle life of the pneumatic pump.

[0026] The pump body 1 consists of at least an air supply section and an extraction section, sealed between the air supply and extraction sections by a diaphragm. The extraction section includes a liquid inlet pipe 12 and a liquid outlet pipe 13. The liquid inlet pipe 12 is positioned below the liquid level. The aeration section 24 and the dosing section 23 are located on the liquid inlet pipe 12. The liquid inlet pipe 12 is a telescopic tube, and the dosing section 23, aeration section 24, and float 21 are also located on the telescopic tube. Because the pneumatic pump is constantly supplying air, the float 21 remains in a constant floating or suspended state, which in turn drives the telescopic tube to expand and contract, ensuring that the telescopic tube remains in the clear liquid above. This ensures that the liquid pumped by the pneumatic pump is relatively clear, reducing the possibility of particulate matter depositing inside the pneumatic pump, extending the pneumatic pump's maintenance cycle, and thus extending its service life.

[0027] The dosing unit 23 includes a medicine chamber 231, which has a medicine outlet 232. A pressure differential valve is provided at the medicine outlet 232. When the air supply unit supplies air, the pressure differential valve opens, and the medicine outlet 232 faces the liquid surface. The pressure differential valve opens only when the pressure in the medicine chamber 231 reaches a certain level. The air pressure in the medicine chamber 231 is released the moment the pressure differential valve opens, which can drive the medicine to instantly enter below the liquid surface, thereby improving the uniformity of the medicine spreading. The air source box of the pneumatic pump itself is used to inflate the medicine chamber 231, and then the pressure can be used to supply air to the medicine chamber 231 to provide a power source for the medicine spreading. At the same time, due to the presence of the pressure differential valve, the air pressure in the medicine chamber 231 will accumulate to a certain level and be released all at once, so that the medicine is sprayed more evenly. The aeration unit 24 includes an aeration pipe 241, which is placed below the liquid surface and has a number of aeration holes. The aeration holes extend below the liquid surface, constantly blowing air into the liquid, accelerating the fusion of the liquid and the reagent, which in turn speeds up the settling of particles. This reduces the amount of sediment entering the pneumatic pump and extends its service life. While adding the reagent, air is continuously blown into the liquid, accelerating the fusion of the reagent and causing particles to settle more quickly.

[0028] The aeration section 24 also includes a booster tank 242, which is connected to the aeration pipe 241 via a pipe 22. A control valve is installed on the pipe 22 to control the flow of the pipe 22. The control valve can also be a differential pressure valve. The booster tank 242 increases the aeration sub-pressure in the aeration section 24, improving aeration efficiency. During aeration, the short-term release of high-pressure gas causes the liquid to churn more vigorously, accelerating the fusion of the reagents and allowing particles to settle more quickly.

[0029] The air supply unit includes a pump cylinder 11, which has a piston inside. A connecting port is provided on the side wall of the pump cylinder 11. A diaphragm is provided at the connecting port, which is connected to the extraction unit. The float 21 is connected to the pump cylinder 11, and the branch pipe 22 is connected to the pump cylinder 11. The deformation of the diaphragm is used to squeeze the liquid, thereby exerting a pumping pressure. The extraction unit includes a cylinder body, which is connected to the pump cylinder 11 through the connecting port. A liquid inlet is provided at the bottom of the cylinder body, and a liquid outlet is provided at the top of the cylinder body. The liquid inlet is connected to the liquid inlet pipe 12, and the liquid outlet is connected to the liquid outlet pipe 13. A one-way liquid inlet valve is provided at the liquid inlet, and a one-way liquid outlet valve is provided at the liquid outlet. The flow direction can be controlled by the one-way liquid inlet valve and the one-way liquid outlet valve during startup.

[0030] Compared with the existing technology, the present invention uses an air source to synchronously supply air to the aeration part 24 and the dosing part 23 during the process of the air pump pumping the liquid, and uses the gas pressure to spray the medicine stored in the dosing part 23 into the liquid, thereby accelerating the sedimentation of solid particles in the liquid. Furthermore, the aeration part 24 will continue to blow air into the liquid to accelerate the combination of the particles in the liquid and the medicine for sedimentation, so that the liquid pumped by the pneumatic pump is relatively clear, reducing the possibility of particles depositing inside the pneumatic pump, extending the maintenance cycle of the pneumatic pump, and thus extending the cycle service life of the pneumatic pump.

[0031] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
