Description

Technical Field

[0001] This application relates to the technical field of liquid filling, and in particular to a cleaning agent filling device. Background Technology

[0002] Liquid filling equipment is widely used in industries such as chemical and pharmaceutical manufacturing to accurately deliver various liquids into designated containers. With the increasing level of industrial automation, these devices not only improve production efficiency but also reduce human error, ensuring consistent product quality. However, in practical applications, effectively handling the side problems that arise during the filling process has become an important issue.

[0003] In existing detergent filling technologies, metering pumps or quantitative pumps are typically used to achieve precise liquid delivery. Specifically, these devices, through pre-set parameters, enable the metering pump to deliver a predetermined amount of liquid from a storage tank to the target container. To ensure filling accuracy and stability, common measures include using high-precision sensors to monitor flow rate, adjusting pump operating frequency, and optimizing pipeline design. Furthermore, some advanced systems are equipped with automatic control systems to monitor and regulate the entire filling process in real time.

[0004] While the methods described above address the accuracy issue of liquid filling to some extent, residual liquid inside the pipeline can leak onto the ground or other non-target areas when changing containers, resulting in a dirty and messy production environment and potentially posing safety hazards. This problem severely impacts the cleanliness and hygiene standards of the production site, necessitating an effective solution. Utility Model Content

[0005] In order to reduce the leakage of residual liquid in the pipeline caused by changing the container during the filling process, this application provides a cleaning agent filling device.

[0006] The cleaning agent filling equipment provided in this application adopts the following technical solution:

[0007] A cleaning agent filling device includes an infusion pump, a three-way valve, an infusion pipe, and a gas infusion pipe.

[0008] The first port of the three-way pipe is used to connect to the outlet of the infusion pump.

[0009] One end of the infusion tube is used to connect to the second port of the tee tube, and the other end of the infusion tube is used to fill the tank with liquid.

[0010] One end of the gas transmission pipe is used to connect to the third port of the tee pipe, and the other end of the gas transmission pipe is used to connect to the gas source.

[0011] By adopting the above technical solution, when the infusion pump stops working, gas is introduced into the tee and infusion tube through the gas supply pipe. The gas can push the liquid remaining in the infusion tube into the container, reducing (or even eliminating) the liquid residue in the infusion tube, thereby reducing the occurrence of dripping. At the same time, this design has a simple structure and is easy to modify, and can be used to improve the automation level and work efficiency of the detergent filling process.

[0012] Preferably, the second port is coaxial with the first port.

[0013] By adopting the above technical solution, the coaxial arrangement of the second pipe opening and the first pipe opening can ensure smooth liquid flow, reduce the phenomenon of slowed flow rate or blockage caused by pipe misalignment, and improve filling efficiency and stability.

[0014] Preferably, it also includes valves.

[0015] The valve is connected between the gas supply pipe and the tee pipe, and the valve is used to control the opening / closing of the gas supply pipe and the tee pipe.

[0016] By adopting the above technical solution, when the infusion pump is working, the valve is closed, preventing liquid from entering the gas delivery pipe. After the infusion pump stops working, the valve opens, and gas is delivered into the tee and the infusion pipe through the gas delivery pipe.

[0017] Preferably, the valve includes a solenoid valve or an electric valve.

[0018] By adopting the above technical solution, the use of solenoid valves can achieve precise control over the on / off state between the gas supply pipe and the tee pipe, further improving the automation and reliability of the filling process and reducing the possibility of human error.

[0019] Preferably, the inner diameter of the third pipe opening is smaller than the inner diameter of the first pipe opening, and the inner diameter of the second pipe opening is equal to the inner diameter of the first pipe opening.

[0020] By adopting the above technical solution, the inner diameter of the third pipe opening is smaller than that of the first pipe opening, increasing the resistance to liquid flowing into the third pipe opening; the inner diameter of the second pipe opening is equal to that of the first pipe opening, reducing the resistance to liquid flowing into the second pipe opening; together, they ensure the consistency and stability of the liquid flow path.

[0021] Preferably, one end of the infusion tube is higher than the other end of the infusion tube.

[0022] By adopting the above technical solution, the combined effect of airflow and gravity reduces the residual liquid in the infusion tube, thereby reducing the risk of liquid leakage when changing the tank.

[0023] Preferably, it also includes a fixed pipe and a connecting pipe.

[0024] One end of the fixed tube is used to connect to the outlet of the infusion pump.

[0025] One end of the connecting pipe is connected to the other end of the fixed pipe, the other end of the connecting pipe is connected to the first pipe opening, and the other end of the connecting pipe is higher than the first end of the connecting pipe.

[0026] By adopting the above technical solution, the design of the fixed pipe and the connecting pipe allows the pipeline layout between the infusion pump and the three-way pipe to be adjusted according to the actual production site and equipment. The design of the other end of the connecting pipe being higher than the first end increases the resistance of the liquid in the fixed pipe and the connecting pipe to the infusion pipe, so that after the infusion pump stops working and the airflow pushes the liquid in the infusion pipe into the tank, the liquid in the connecting pipe will not flow into the infusion pipe.

[0027] Preferably, the angle between the axis of the third port and the axis of the second port is an obtuse angle.

[0028] By adopting the above technical solution, the airflow can enter the infusion tube more smoothly, effectively promote the discharge of liquid in the tube, reduce residual liquid leakage, and thus maintain a clean and tidy production environment.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. By setting up an air supply pipe to send air into the three-way pipe, the residual liquid in the infusion tube can be effectively pushed into the tank, avoiding the problem of liquid leakage when changing the tank, thus maintaining a clean and tidy production environment;

[0031] 2. The connection design between the gas delivery pipe and the tee pipe allows the gas to directly act on the liquid in the infusion pipe, enhancing the venting effect, further reducing the dripping of residual liquid, and improving the reliability and safety of the equipment;

[0032] 3. The structure is simple and easy to implement, requiring no complex control system, which reduces manufacturing costs and maintenance difficulty, while improving the overall system stability and working efficiency. Attached Figure Description

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] Reference Figure 1 This application discloses a cleaning agent filling device including an infusion pump 1, a fixed pipe 2, and a connecting pipe 3.

[0038] Infusion pump 1 includes either a metering pump or a quantitative pump. Both types of pumps enable precise liquid delivery. For example, a positive displacement pump can be selected as infusion pump 1, characterized by its ability to maintain a constant displacement during each run, suitable for applications requiring highly precise control of liquid volume. Another option is a centrifugal pump, although its displacement may be affected by pressure, it can still meet basic filling requirements in certain situations.

[0039] The inlet of the infusion pump 1 is connected to the tank 0, which contains liquid to be filled. The liquid to be filled can be a cleaning agent such as hand sanitizer or dish soap.

[0040] One end of the fixed pipe 2 is used to connect to the outlet of the infusion pump 1. The fixed pipe 2 can be a straight pipe or a bent pipe, which can be selected according to the actual production site; preferably, the fixed pipe 2 is a rigid pipe.

[0041] One end of the connecting pipe 3 is connected to the other end of the fixed pipe 2, and the other end of the connecting pipe 3 is higher than the end of the connecting pipe 3 connected to the fixed pipe 2.

[0042] Reference Figure 1 and Figure 2 The cleaning agent filling equipment also includes a three-way pipe 4, an infusion pipe 5, and an air infusion pipe 6.

[0043] The tee pipe 4 has three interconnected ports, namely the first port 41, the second port 42, and the third port 43.

[0044] The second port 42 is coaxial with the first port 41, and the angle between the axis of the third port 43 and the axis of the second port 42 is an obtuse angle.

[0045] The inner diameter of the third port 43 is smaller than the inner diameter of the first port 41, and the inner diameter of the second port 42 is equal to the inner diameter of the first port 41.

[0046] The other end of the connecting pipe 3 is connected to the first port 41, so that the three-way pipe 4 is connected to the outlet of the infusion pump 1; one end of the infusion pipe 5 is connected to the second port 42, and the other end of the infusion pipe 5 is used to fill the tank with liquid; one end of the gas infusion pipe 6 is connected to the third port 43. The other end of the gas infusion pipe 6 is connected to a gas source. The gas source can be an air compressor, a gas storage tank, etc.

[0047] The three-way connector 4 is responsible for guiding the liquid output from the infusion pump 1 into the infusion tube 5, and allowing gas to enter the infusion tube 5 through the gas delivery tube 6. In practical applications, the three-way connector 4 can be made of stainless steel, which has good corrosion resistance and durability, and can withstand the erosion of various chemical reagents.

[0048] Meanwhile, the other end of the infusion tube 5 is lower than the end of the infusion tube 5 connected to the three-way tube 4, so as to facilitate the flow of liquid in the infusion tube 5 into the tank. Preferably, the infusion tube 5 is a flexible tube, so as to facilitate the insertion or removal of the infusion tube 5 into the tank; the infusion tube 5 can be made of silicone or polyurethane tubing, which are soft and not easy to age, and are suitable for long-term use.

[0049] The cleaning agent filling equipment also includes a valve 7. The valve 7 is connected between the gas supply pipe 6 and the tee pipe 4, and is used to control the opening and closing of the gas supply pipe 6 and the tee pipe 4. The valve 7 may be a solenoid valve or an electric valve.

[0050] The implementation principle of a cleaning agent filling device according to an embodiment of this application is as follows: During the filling process, valve 7 is closed, and the infusion pump 1 delivers liquid from tank 0 to the container. When the container needs to be replaced, the infusion pump 1 stops working, and at this time, valve 7 opens to introduce gas into the three-way pipe 4 through the gas infusion pipe 6. The gas can push the residual liquid in the infusion pipe 5 into the container, and then a new container is replaced to avoid liquid leakage. In this way, not only can pollution of the production environment be effectively reduced, but work efficiency can also be improved and maintenance costs reduced.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
