Description

TECHNICAL FIELD

[0001] The utility model relates to gear metering pump set technical field, more specifically, relate to a kind of gear metering pump set of flush cleaning. BACKGROUND

[0002] The working principle of gear metering pump set is based on the meshing motion of gears. When the driving device drives the gears to rotate, the two gears mesh with each other, forming a low-pressure area at the inlet of the pump. Fluid is sucked into the pump cavity under the action of pressure difference. With the rotation of the gear, the fluid is carried by the gear tooth groove and transported along the pump cavity to the outlet direction. At the outlet, due to the meshing of the gears, the fluid is extruded out of the pump cavity, forming a high-pressure area, thereby realizing the transportation and pressurization of the fluid. At the same time, since the number of teeth and the size of the gear are fixed, the volume of fluid transported per revolution is also fixed, so the flow rate of the fluid can be accurately measured by controlling the rotational speed of the gear.

[0003] Gear metering pump set needs to be cleaned regularly in different production processes. In chemical production, different chemical reagents may react with each other, which may corrode pump body parts or affect the accuracy of the next measurement. The traditional gear metering pump set has a complex structure and contains multiple closely fitted gears, shafts, seals, and cavities. For example, the narrow gap between the gear and the pump body, the fitting part of the shaft and the bearing, etc. are easy to become cleaning dead angles. These parts are easy to leave residues during normal production, and due to the narrow space, conventional cleaning tools and methods are difficult to reach. SUMMARY

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a gear metering pump set for easy flushing and cleaning to solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solution:

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-3 In this utility model, a gear metering pump set for convenient rinsing and cleaning includes a pump box 1 and a gear metering pump set 2 installed inside the pump box 1. A rinsing pipe 3 is fixedly installed on the pump box 1. Both ends of the rinsing pipe 3 are fixedly connected to and communicate with the water inlet pipe of the gear metering pump set 2. A fan blade 4 is rotatably installed inside the rinsing pipe 3. A medicine tube 5 is fixedly installed on one side of the rinsing pipe 3. A medicine pushing piston 6 is slidably installed inside the medicine tube 5. An electric push rod 7 and a storage battery 8 are fixedly installed on the pump box 1. The electric push rod 7 and the storage battery 8 are electrically connected. The output end of the electric push rod 7 is fixedly connected to the medicine pushing piston 6. A medicine outlet channel 10 is opened inside the fan blade 4. A medicine passage pipe 11 is fixedly installed at the bottom of the medicine tube 5 and communicates with it. The other end of the medicine passage pipe 11 passes through the medicine tube 5 and is rotatably connected to the fan blade 4. The inside of the medicine passage pipe 11 is connected to the medicine outlet channel 10. The inside of the medicine tube 5 is filled with cleaning agent.

[0024] In this invention, when the inside of the pump box 1 needs to be flushed and cleaned, the liquid entering through the inlet pipe of the gear metering pump set 2 is guided through the flushing pipe 3. By controlling the circuit between the electric push rod 7 and the battery 8, the electric push rod 7 moves the push piston 6, pushing the medicine in the medicine tube 5 through the medicine passage pipe 11 into the medicine outlet channel 10, and flowing out from the outlet of the medicine outlet channel 10. As the liquid flows, the fan blade 4 rotates, and the rotating fan blade 4 will generate strong turbulence and vortex in the fluid in the pipe, thereby assisting the mixing of medicine and fluid. After the fluid containing medicine enters the gear metering pump set 2, it can enter the narrow space to flush and neutralize some residual chemical reagents. This not only replaces disassembly and cleaning, but also facilitates cleaning of the four corners, improves the cleaning efficiency of the gear metering pump set, and reduces the burden of flushing and cleaning work.

[0025] Please see Figure 3 The flushing pipe 3 has a micro generator 9 fixedly installed inside. The input shaft of the micro generator 9 is fixedly connected to the rotating shaft of the fan blade 4, and the output end of the micro generator 9 is electrically connected to the storage battery 8.

[0026] In this invention, when the fan blade 4 is driven to rotate by the fluid in the flushing pipe 3, it drives the input shaft of the micro generator 9 to rotate, thereby generating electricity and storing the electrical energy in the battery 8, which is more energy-efficient. Furthermore, by adjusting the connection method between the micro generator 9 and the battery 8 and changing the output power of the battery 8, the micro generator 9 can be converted into an electric motor, thereby actively driving the fan blade 4 to rotate, increasing the fluid flow rate and improving the flushing and cleaning effect. The adjustment of the connection method between the micro generator 9 and the battery 8 is a known prior art and will not be described in detail here.

[0027] Please see Figure 1 and Figure 2 The cleaning agent is a solvent that neutralizes harmful substances, and this solvent is one of gasoline, kerosene, water, and alkaline solution.

[0028] In this invention, a suitable and corresponding solvent is selected as the cleaning agent based on the properties of the fluid output by the gear metering pump set, thereby reducing the corrosion of the internal parts of the gear metering pump set by chemical reagents and extending the service life of the gear metering pump set.

[0029] Please see Figure 3 The outlet of the drug outlet channel 10 is oriented in the same direction as the liquid flow in the inlet pipe of the gear metering pump group 2.

[0030] In this invention, the solvent flowing out of the drug outlet channel 10 is ensured to flow in the same direction as the fluid, which facilitates the mixing and rinsing of the two.

[0031] Please see Figure 1 Among them, a solenoid valve 12 is fixedly installed on the inlet pipe of the gear metering pump group 2. The solenoid valve 12 is located between the two ends of the flushing pipe 3 and the connection point of the inlet pipe of the gear metering pump group 2.

[0032] In this invention, by controlling the opening and closing of the solenoid valve 12, the flow of the first section of the inlet pipe of the gear metering pump group 2 is changed. When the solenoid valve 12 is closed, the fluid in the inlet pipe can only flow through the flushing pipe 3, ensuring that the fluid and cleaning agent are mixed before entering the gear metering pump group 2.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
