Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a mixer. Background Technology

[0002] Mold release agents are functional substances placed between the mold and the finished product. In the rubber and plastics manufacturing industry, they are essential additives used when manufacturing molded products to facilitate demolding, improve production efficiency, extend mold life, and ensure a smooth, dimensionally accurate product while reducing waste. Mold release agents require water to form a fully mixed solution before use.

[0003] The Chinese utility model patent application number is CN202322436418.4, and the patent title is "An Automatic Flow Control Proportioning Mixer." Existing mixing equipment injects clean water through an inlet pipe in a conduit assembly. After the clean water is injected into the dosing pump, the chemical is diluted, and then the diluted chemical is stored in a storage tank. This method results in poor mixing effect, smaller mixing volume per batch, and low efficiency. Summary of the Invention

[0004] In order to address the technical deficiencies mentioned in the background section, the purpose of this utility model is to provide a mixer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mixer includes a mixing tank for mixing liquids, a water adding device, a dosing device, a stirring device, and a pneumatic control device for discharging the mixed liquid. The lower end of the mixing tank is provided with a water inlet, a dosing inlet, and a liquid extraction outlet. The stirring device is disposed inside the mixing tank for stirring the liquid therein. The dosing device includes a dosing suction assembly, a first dosing pipe, a dosing device, and a second dosing pipe. The dosing suction assembly is disposed outside the mixing tank, with one end located inside a dosing tank and the other end connected to the dosing device via the second dosing pipe. The dosing device is connected to the dosing inlet via the second dosing pipe. One end of the pneumatic control device is connected to the liquid extraction outlet, and the other end is connected to an external storage device.

[0007] By adopting the above technical solution, the drug delivery assembly can transport the drug from the external supply tank to the dosing unit for storage. When needed, it can then be transferred from the dosing unit to the mixing tank, resulting in higher drug delivery efficiency. Furthermore, it is convenient to replace the supply tank when the drug is used up. When mixing is required, the dosing unit and water supply device simultaneously supply drug and water to the mixing tank, while the stirring device performs stirring simultaneously, ensuring more uniform mixing and higher efficiency. Moreover, the mixing tank has a larger capacity, allowing for the mixing of more drugs and further increasing efficiency. The mixed solution is output to the corresponding equipment via a pneumatic control device, enabling fully automated operation, significantly reducing manual labor and lowering costs.

[0008] Furthermore, the drug aspiration assembly includes a liquid aspiration pump, a pipette, and a detection tube for liquid level detection. The liquid aspiration pump is mounted on the mixing tank. One end of the pipette is connected to the liquid aspiration pump, and the other end is located at the bottom of the drug supply tank, facilitating the replacement of raw materials and making it very convenient to use. One end of the detection tube is connected to the liquid aspiration pump, and the other end is located inside the drug supply tank. The height of the other end of the detection tube is higher than the height of the other end of the pipette, facilitating real-time monitoring of the remaining drug level in the drug supply tank, improving safety performance, and ensuring the mixing accuracy of the mixture.

[0009] Furthermore, the other end of the second delivery tube passes through the dosing port located at the upper end of the mixing tank, allowing the liquid medicine to fall into the mixing tank from above, which helps to disperse the liquid medicine, improve the mixing effect and the uniformity of the mixing.

[0010] Furthermore, the stirring device includes a stirring motor, a stirring element, and a liquid level monitoring component. The stirring motor is located at the upper end of the mixing tank, and its output shaft is connected to one end of the stirring element, the other end of which is located inside the mixing tank. The liquid level monitoring component is used to monitor the liquid level of the mixture within the mixing tank.

[0011] Furthermore, the liquid level monitoring component includes a mounting base, a minimum liquid level monitoring rod, and a maximum liquid level monitoring rod. The mounting base is fixed to the upper inner side of the mixing tank. One end of both the minimum and maximum liquid level monitoring rods is fixed to the mounting base, and the other ends of both rods are vertically arranged. The height of the other end of the minimum liquid level monitoring rod is lower than that of the other end of the maximum liquid level monitoring rod, which allows for accurate detection and coordination of the liquid level in the mixing tank, resulting in higher automation efficiency.

[0012] Furthermore, the liquid level monitoring assembly also includes a float probe, which is spaced apart from the mounting base. One end of the float probe is fixed to the upper inner side of the mixing tank, and the height of the other end of the float probe is the same as the height of the other end of the lowest liquid level monitoring rod, further improving detection efficiency and control performance.

[0013] Furthermore, the water supply device includes an inlet connector connected to an external water supply device, a water filter, a first inlet pipe connected between the inlet connector and the water filter, a water pump located on one side of the water filter, and a second inlet pipe connected between the water pump and the inlet, facilitating automatic control of the water intake and improving intelligent efficiency. The inlet end of the water pump is connected to the outlet end of the water filter.

[0014] Furthermore, the pneumatic control device includes an air inlet connector, an air filter, a diaphragm pump, a first air inlet pipe connected between the air inlet connector and the air inlet end of the air filter, a second air inlet pipe connected between the air outlet end of the air filter and the diaphragm pump, a first inlet pipe, and a second inlet pipe. The first inlet pipe is connected between the liquid extraction port and the diaphragm pump, and the second inlet pipe is connected between the second inlet pipe and the output connector of the mixture, for outputting the mixed mixture, facilitating control of the output amount of the mixture, and stabilizing the internal working air pressure of the mixing chamber.

[0015] Furthermore, the dosing device, the water filter, and the air filter are arranged in an L-shape, and the diaphragm pump is located within the area enclosed by the dosing device, the water filter, and the air filter. This design is compact, rationally laid out, and improves space utilization.

[0016] In summary, the beneficial effects of this utility model are as follows:

[0017] The drug suction component in this invention can transport the drug from the external drug supply tank to the dosing device for storage. When needed, it is then transported from the dosing device to the mixing tank, resulting in higher drug supply efficiency. Furthermore, it is convenient to replace the drug supply tank when the drug is used up. When mixing is required, the dosing device and water supply device simultaneously supply drug and water to the mixing tank, while the stirring device simultaneously performs stirring, resulting in more uniform mixing and higher efficiency. Moreover, the mixing tank has a larger capacity, allowing for the mixing of more drugs and further increasing efficiency. The mixed solution is output to the corresponding equipment via a pneumatic control device, enabling fully automated operation, significantly reducing manual labor and lowering costs.

[0027] The following is in conjunction with the appendix Figure 1-4 The embodiments of this utility model will be described in further detail below.

[0028] A mixer 1, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a mixing tank 2 for liquid mixing, a water adding device, a dosing device, a stirring device 5, and a pneumatic control device for discharging the mixed liquid. The lower end of the mixing tank 2 is provided with a water inlet, a dosing port, and a liquid extraction port at intervals. The stirring device 5 is located inside the mixing tank 2 and is used to stir the liquid within it. The dosing device includes a suction assembly 41, a first delivery pipe 42, a dosing device 43, and a second delivery pipe 44. The suction assembly 41 is located outside the mixing tank 2, with one end of the suction assembly 41 inside the supply tank, and the other end of the suction assembly 41 connected to the dosing device 43 via the second delivery pipe 44. The dosing device 43 is connected to the dosing port via the second delivery pipe 44. One end of the pneumatic control device is connected to the liquid extraction port, and the other end is connected to an external storage device. The structure of the supply tank is not shown in the figure. The first delivery pipe 42 is shown schematically, and the end of the first delivery pipe 42 is not shown connected to the suction pump 411 of the suction assembly 41.

[0029] The drug delivery assembly 41 transports the drug from the external drug supply tank to the dosing device 43 for storage. When needed, the drug is then transferred from the dosing device 43 to the mixing tank 2, resulting in higher drug supply efficiency. Furthermore, it facilitates easy replacement of the drug supply tank when the drug is depleted, making it very convenient to use. When mixing is required, the dosing device 43 and the water supply device simultaneously supply drug and water to the mixing tank 2, while the stirring device 5 performs stirring operations simultaneously. This ensures more uniform mixing and higher efficiency. Moreover, the mixing tank 2 has a larger capacity, allowing for the mixing of more drugs and further increasing efficiency. The mixed solution is output to the corresponding equipment via a pneumatic control device, enabling fully automated operation, significantly reducing manual labor and lowering costs.

[0030] In some embodiments, the drug aspiration assembly 41 includes a liquid aspiration pump 411, a pipette 412, and a detection tube 413 for liquid level detection. The liquid aspiration pump 411 is mounted on the mixing tank 2. One end of the pipette 412 is connected to the liquid aspiration pump 411, and the other end of the pipette 412 is located at the bottom of the drug supply tank, facilitating the replacement of raw materials and making it very convenient to use. One end of the detection tube 413 is connected to the liquid aspiration pump 411, and the other end of the detection tube 413 is located inside the drug supply tank. The height of the other end of the detection tube 413 is higher than the height of the other end of the pipette 412, facilitating real-time monitoring of the remaining drug level in the drug supply tank, improving safety performance, and ensuring the mixing accuracy of the mixture. The dosage can be electrically controlled by the liquid aspiration pump 411, resulting in higher control precision.

[0031] Preferably, the other end of the second drug delivery tube 44 passes through the drug inlet and is located at the upper end of the mixing tank 2, so that the drug liquid falls into the mixing tank 2 from above. The impact force of the falling drug liquid also helps to disperse the drug liquid, improve the mixing effect and the uniformity of the mixing.

[0032] In some embodiments, please refer to Figure 1 , Figure 4 The stirring device 5 includes a stirring motor 51, a stirring element 52, and a liquid level monitoring component 53.

One end of both the minimum liquid level monitoring rod 532 and the maximum liquid level monitoring rod 533 is fixed to the mounting base 531, and the other end of both rods is vertically arranged. The height of the other end of the minimum liquid level monitoring rod 532 is lower than the height of the other end of the maximum liquid level monitoring rod 533, which can accurately detect and coordinate the liquid level in the mixing tank 2, resulting in higher automation efficiency.

[0034] For preferred options, please refer to [the provided text]. Figure 2 , Figure 4The liquid level monitoring assembly 53 also includes a float probe 534, which is spaced apart from the mounting base 531. One end of the float probe 534 is fixed to the upper inner side of the mixing tank 2, and the height of the other end of the float probe 534 is set to the same height as the other end of the lowest liquid level monitoring rod 532, further improving detection efficiency and control performance.

[0035] To improve safety, an overflow port 21 can be installed on one side of the mixing tank 2. The height of the overflow port 21 is higher than the height of the other end of the highest liquid level monitoring rod 533. When there is too much mixed liquid, it can flow out from the overflow port 21, which is beneficial to protect the equipment and the production environment, recover the overflowed mixed liquid, and save energy.

A control valve 68 is installed between the first delivery pipe 66 and the second delivery pipe 67 to control the flow rate.

[0039] For preferred options, please refer to [the provided text]. Figure 2The dosing device 43, water filter 32, and air filter 62 are arranged in an L-shape, and the diaphragm pump 63 is located within the area enclosed by the dosing device 43, water filter 32, and air filter 62. The structure is compact, the layout is reasonable, and the space utilization is improved.

[0040] The lower end of the mixing tank 2 is also provided with a cleaning port.
