[0001] This application relates to the field of liquid mixing technology, specifically to a liquid mixing device. Background Technology

[0002] Liquid mixing devices are widely used in chemical, pharmaceutical, and food processing industries to mix various liquids in a specific ratio. Traditional liquid mixing devices mostly employ stirring or static mixers, which, while achieving basic mixing functions, still have shortcomings in mixing efficiency, energy consumption control, automation level, and handling high-viscosity or impurity-containing liquids. In recent years, with the development of industrial automation and intelligent manufacturing, higher demands have been placed on the efficiency, precision, and intelligence of liquid mixing devices.

[0003] A prior patent (publication number: CN218422605U) discloses a liquid mixing device, including a mixing tank.

[0004] However, it was found in the above solution that multi-stage mixing could not be achieved when mixing materials, resulting in low mixing efficiency and easy occurrence of uneven mixing or clumping. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a liquid mixing device that has the advantages of enabling multi-stage stirring of materials and improving mixing efficiency. It solves the problems that transmission mixing methods and the above-mentioned solutions cannot achieve multi-stage stirring, resulting in low mixing efficiency and easy occurrence of uneven stirring or clumping.

[0006] To achieve the above objectives, this application provides the following technical solution: a liquid mixing device, comprising a mixing tank 1, a mixing tank 2, and a mixing tank 3. The inner walls of the mixing tanks 1, 2, and 3 are all fixedly equipped with equally spaced baffles. A connecting rod is rotatably connected to the inner walls of each of the mixing tanks 1, 2, and 3. Two stirring blades are fixedly connected to the outer surface of each connecting rod. A motor is fixedly installed at the top of one of the connecting rods. A pulley 1, two pulleys 2, and a pulley 3 are provided above the mixing tank 1. The inner walls of the pulleys 1, 2, and 3 are fixedly connected to the outer surfaces of the corresponding connecting rods. A synchronous belt 1 is drivingly connected between the pulley 1 and the corresponding pulley 2, and a synchronous belt 2 is drivingly connected between the pulley 3 and the corresponding pulley 2.

[0007] In order to achieve multi-stage mixing of materials through the above scheme, connecting rods are installed on the inner walls of mixing tank 1, mixing tank 2, and mixing tank 3. The stirring blades are fixed to the surface of the corresponding connecting rods. A motor causes one of the connecting rods to rotate, which in turn drives pulley 1 to rotate. Pulley 1, through synchronous belt 1, causes pulley 2 to rotate. Through the connection between pulley 2 and synchronous belt 2, pulley 3 rotates. This allows multiple connecting rods to rotate synchronously, and each connecting rod rotates at a different speed. The material is transferred between mixing tank 1, mixing tank 2, and mixing tank 3, and stirred sequentially to achieve staged mixing and improve the mixing effect. Furthermore, baffles at equal intervals are installed on the inner wall of each mixing tank to disrupt the liquid flow direction and further improve the mixing efficiency.

[0008] Furthermore, a fixing frame is fixedly connected to the upper surface of the motor, and the bottom surface of the fixing frame is fixedly connected to the upper surface of the mixing tank.

[0009] The above method involves installing the mounting bracket on the upper surface of the motor as a fixed connection, and connecting the bottom surface of the mounting bracket to the upper surface of the mixing tank as a fixed connection, thereby achieving the effect of positioning and installing the motor.

[0010] Furthermore, the outer surfaces of mixing tank one, mixing tank two, and mixing tank three are all fixedly connected to mounting brackets, and the outer surface of mixing tank one is fixedly connected to a feed pipe.

[0011] The above scheme involves fixing mounting brackets on the surfaces of mixing tank 1, mixing tank 2, and mixing tank 3 to support them. A feed pipe is installed on the surface of mixing tank 1 to facilitate the addition of materials into the interior of mixing tank 1 for mixing.

[0012] Furthermore, a mounting base plate is provided below the mixing tank, and the bottom surface of each mounting bracket is fixedly connected to the upper surface of the mounting base plate.

[0013] By using the above method, the mounting base plate is placed below the first mixing tank, and the upper surface of the mounting base plate is connected to the corresponding mounting bracket, which can fix the mounting bracket and improve the stability of the first, second, and third mixing tanks.

[0014] Furthermore, the bottom surface of the mixing tank is fixedly connected to a discharge pipe, and a pump body is fixedly installed at the other end of the discharge pipe.

[0015] With the above scheme, the discharge pipe is installed on the bottom of the mixing tank, which facilitates the transfer of the mixed material inside the mixing tank. The pump body is installed at the other end of the discharge pipe, which allows the material inside the mixing tank to be extracted.

[0016] Furthermore, a conveying pipe is fixedly installed at the output end of the pump body one, the outer surface of the conveying pipe one is fixedly connected to the inner wall of the mixing tank two, and a discharge pipe is fixedly connected to the bottom surface of the mixing tank three.

[0017] With the above scheme, the conveying pipe is installed at the output end of the pump body, and the other end of the conveying pipe is connected to the mixing tank. The pump body allows the material to be transferred to the interior of the mixing tank for stirring through the conveying pipe. The discharge pipe is installed on the bottom of the mixing tank, and the discharge pipe facilitates the discharge of the finally mixed material.

[0018] Furthermore, the bottom surface of the mixing tank is fixedly connected to the discharge pipe, and the other end of the discharge pipe is fixedly installed with the pump body.

[0019] With the above scheme, the discharge pipe 2 is installed on the bottom of the mixing tank 2, and the mixed material inside the mixing tank 2 is discharged through the discharge pipe 2. The pump body 2 is installed at the other end of the discharge pipe 2, and the material inside the mixing tank 2 is extracted through the connection between the pump body 2 and the discharge pipe 2.

[0020] Furthermore, a conveying pipe is fixedly installed at the output end of the pump body two, and the outer surface of the conveying pipe two is fixedly connected to the outer surface of the mixing tank three. Atomizing nozzles are fixedly installed at the other ends of the feed pipe, the conveying pipe one, and the conveying pipe two.

[0021] With the above scheme, the second conveying pipe is installed at the output end of the second pump body, and the other end of the second conveying pipe is connected to the surface of the third mixing tank, so that the mixed material inside the second mixing tank can be transferred to the third mixing tank for final mixing.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This liquid mixing device comprises three components: pulley one, pulley two, and pulley three; and mixing tank one, mixing tank two, and mixing tank three. A motor drives pulley one to rotate, which in turn, under the action of synchronous belt one, causes pulley two to rotate, and under the action of synchronous belt two, causes pulley three to rotate. This, in turn, causes the corresponding connecting rods to rotate, which in turn drives the corresponding stirring blades to rotate. Each connecting rod rotates at a different speed, allowing the material to be mixed step-by-step in each different mixing tank, improving the mixing effect.

[0033] Please see Figure 1 , Figure 2 and Figure 4 A fixing bracket 13 is fixedly connected to the upper surface of the motor 12.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The outer surfaces of mixing tank 1, mixing tank 2, and mixing tank 3 are all fixedly connected with mounting brackets 14. The outer surface of mixing tank 1 is fixedly connected with a feed pipe 16. The mounting brackets 14 are fixedly fixed on the surfaces of mixing tank 1, mixing tank 2, and mixing tank 3, and the mounting brackets 14 support the mixing tank 1, mixing tank 2, and mixing tank 3. The feed pipe 16 installed on the surface of mixing tank 1 makes it easy to add materials into the interior of mixing tank 1 for mixing.

[0035] Please see Figure 1 , Figure 2 and Figure 3A mounting base plate 15 is provided below the mixing tank 1. The bottom surface of each mounting bracket 14 is fixedly connected to the upper surface of the mounting base plate 15. By placing the mounting base plate 15 below the mixing tank 1 and connecting the upper surface of the mounting base plate 15 to the corresponding mounting bracket 14, the mounting bracket 14 can be fixed, thereby improving the stability of the mixing tank 1, the mixing tank 2, and the mixing tank 3.

[0036] Please see Figure 2 , Figure 3 and Figure 4 The bottom surface of the mixing tank 1 is fixedly connected to the discharge pipe 17, and the other end of the discharge pipe 17 is fixedly installed with the pump body 18. The discharge pipe 17 is installed on the bottom surface of the mixing tank 1, so that the mixed material inside the mixing tank 1 can be easily transferred out. The pump body 18 is installed on the other end of the discharge pipe 17, so that the material inside the mixing tank 1 can be extracted through the pump body 18 and the discharge pipe 17.

[0037] Please see Figure 2 , Figure 3 and Figure 4 A conveying pipe 19 is fixedly installed at the output end of the pump body 18. The outer surface of the conveying pipe 19 is fixedly connected to the inner wall of the mixing tank 2. A discharge pipe 23 is fixedly connected to the bottom surface of the mixing tank 3. The conveying pipe 19 is installed at the output end of the pump body 18, and the other end of the conveying pipe 19 is connected to the mixing tank 2.

The discharge pipe 20 is installed on the bottom surface of the mixing tank 2, and the mixed material inside the mixing tank 2 is discharged through the discharge pipe 20. The pump body 21 is installed on the other end of the discharge pipe 20. Through the connection between the pump body 21 and the discharge pipe 20, the material inside the mixing tank 2 is extracted.

[0039] Please see Figure 2 and Figure 4A conveying pipe 22 is fixedly installed at the output end of pump body 21. The outer surface of conveying pipe 22 is fixedly connected to the outer surface of mixing tank 3. Atomizing nozzles 24 are fixedly installed at the other end of feed pipe 16, conveying pipe 19, and conveying pipe 22. By installing conveying pipe 22 at the output end of pump body 21 and connecting the other end of conveying pipe 22 to the surface of mixing tank 3, the mixed material inside mixing tank 22 can be transferred to mixing tank 3 for final mixing. The atomizing nozzles 24 installed at the other end of feed pipe 16, conveying pipe 19, and conveying pipe 22 can atomize the liquid and spray it into the corresponding mixing tank, increasing the liquid contact area and improving mixing efficiency.

[0040] This embodiment of a liquid mixing device includes components such as pulley 7, pulley 9, and pulley 11, and mixing tanks 1, 2, and 3. A motor 12 drives pulley 7 to rotate, which in turn, under the action of synchronous belt 8, causes pulley 9 to rotate, and under the action of synchronous belt 10, causes pulley 11 to rotate. This, in turn, causes the corresponding connecting rod 4 to rotate, which in turn drives the corresponding stirring blade 5 to rotate. Each connecting rod 4 rotates at a different speed, allowing the material to be mixed step-by-step in each different mixing tank, improving the mixing effect. A baffle 6 is installed to disrupt the liquid flow direction, further improving mixing efficiency. Atomizing nozzles 24 are installed at the outlets of the feed pipe 16, conveying pipe 19, and conveying pipe 22 to atomize the liquid and spray it into the corresponding mixing tanks, increasing the liquid contact area and improving mixing efficiency.

[0041] It should be noted that the bottom surfaces of pump body 18 and pump body 21 are connected and fixed to the upper surface of mounting base plate 15, so that pump body 18 and pump body 21 can work stably. The modules of pulley 1 7, pulley 2 9 and pulley 3 11 decrease sequentially. When pulley 1 7 rotates pulley 2 9 through synchronous belt 1 8, the rotation speed of connecting rod 4 is twice as fast as that of the first connecting rod 4. When pulley 3 11 rotates, the rotation speed of connecting rod 4 inside mixing tank 3 is twice as fast as that of connecting rod 4 inside mixing tank 2.

[0042] The working principle of the above embodiments is as follows:

[0043] Material is transferred to the interior of mixing tank 1 through feed pipe 16 and atomizing nozzle 24. At this time, motor 12 is started, causing pulley 7 to rotate. Under the action of synchronous belt 8, pulley 9 rotates, and under the action of synchronous belt 10, pulley 11 rotates, thereby causing the corresponding connecting rod 4 to rotate. The connecting rod 4 drives the corresponding stirring blade 5 to rotate, and the material is stirred inside mixing tank 1. After stirring, the material is transferred to the inner wall of mixing tank 2 through discharge pipe 17, pump body 18, and conveying pipe 19. The stirring blades 5 stir the material, and then, under the action of the discharge pipe 20, pump body 21, and conveying pipe 22, the material is transferred to the interior of the mixing tank 3. Finally, the stirring blades 5 inside the mixing tank 3 stir the material. Since the rotation speed of each connecting rod 4 is different, the material can be mixed step by step in each different mixing tank, improving the mixing effect. The installed baffle 6 can disrupt the liquid flow direction, further improving the mixing efficiency. The atomizing nozzle 24 can atomize the liquid and spray it into the corresponding mixing tank, increasing the liquid contact area and improving the mixing efficiency.
