Description

Technical Field

[0001] This utility model relates to the field of chemical raw material mixing technology, and more specifically, to a high-efficiency chemical raw material mixing equipment. Background Technology

[0002] In industries such as coatings and inks, food and beverages, and electronics, the mixing and stirring of chemical raw materials is a necessary step to obtain the desired product.

[0003] For example, an existing patent (publication (announcement) number: CN221131938U) discloses a high-efficiency mixing device for chemical processes, including a box body. A conveying shell is fixedly connected to the top of the box body, and a first drive motor is installed on one side of the box body. A fixed shaft is fixedly connected to the output end of the first drive motor. This high-efficiency mixing device for chemical processes, by setting up a first drive motor, simultaneously starts the first drive motor and a third drive motor. The first drive motor drives the mixing box to rotate forward through the fixed shaft, and the third drive motor drives the stirring rod to rotate in reverse through the connecting shaft. Since the connecting shaft and the fixed shaft rotate in opposite directions, the stirring rod and the mixing box can improve the mixing efficiency of the raw materials. When the mixing box rotates, the limiting block will rotate inside the limiting groove, thereby improving the stability of the mixing box when rotating and preventing the mixing box from accidentally tilting inside the box body. This solves the problems of poor raw material mixing efficiency and poor stability of the mixing box.

[0004] However, when using the above-mentioned mixing equipment, the raw materials are added through the discharge port at the top of the mixing tank. For some powdered chemical raw materials, this addition will cause certain stratification on the top surface of the mixture, requiring a long time to stir in order to make the raw materials evenly mixed, resulting in low mixing efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-efficiency mixing equipment for chemical raw materials. This solves the problem that existing mixing equipment adds raw materials through the discharge port at the top of the mixing tank. For some powdered chemical raw materials, this addition will cause certain stratification on the top surface of the mixture, requiring a long time to stir in order to make the raw materials uniformly mixed, resulting in low mixing efficiency.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a high-efficiency mixing equipment for chemical raw materials, including a mixing tank, a support frame fixedly installed at the bottom of the mixing tank, a feed inlet opened at the top of the mixing tank, a drive seat fixedly installed on one side of the mixing tank along its length, a drive shaft rotatably connected inside the mixing tank, a drive motor capable of driving the drive shaft to rotate fixedly installed on the drive seat, a stirring blade provided on the drive shaft, and a feeding assembly provided on the mixing tank;

[0007] The feeding assembly includes feeding holes evenly distributed on the drive shaft. The drive shaft has a conveying pipe groove communicating with the feeding holes. A connecting pipe communicating with the conveying pipe groove is rotatably connected to the drive shaft. A three-way pipe is fixedly connected to the top of the connecting pipe. A three-way control valve is provided on the three-way pipe. A material rack is fixedly installed on the top of the mixing box. A feeding hopper is fixedly installed on the material rack, and the bottom end of the feeding hopper is connected to the three-way pipe.

[0008] A booster assembly is provided on the other side of the mixing tank along its length, and a circulating flushing assembly is also connected to the three-way pipe.

[0009] Preferably, the top port of the connecting pipe is higher than the top surface of the mixing box, and the tee pipe is fixedly installed on the top of the mixing box.

[0010] Preferably, the booster assembly includes a second drive base, which is fixedly installed on the side of the mixing box opposite to the first drive base. A booster motor is fixedly installed on the second drive base. A drive rod is concentrically rotatably connected inside the drive shaft. The output end of the booster motor is fixedly connected to one end of the drive rod. A spiral auger is provided on the drive rod.

[0011] Preferably, the drive shaft and the drive rod rotate in opposite directions, or the drive shaft and the drive rod rotate in the same direction but with a speed difference.

[0012] Preferably, the circulating flushing assembly includes a circulating pump, the output end of which is connected to a three-way pipe, the input end of which is fixedly connected to a circulating pipe, and the end of the circulating pipe away from the circulating pump is fixedly connected to a mixing tank.

[0013] Preferably, a switching valve is provided at the end of the circulation pipe near the mixing tank.

[0014] Preferably, the three ports of the three-way pipe correspond one-to-one with the connecting pipe, the feed hopper, and the circulating pump, and the three-way control valve is used to control the connection or closure of the connecting pipe, the feed hopper, the circulating pump and the three-way pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention adds powdered raw materials into the feeding hopper, and the feeding hopper is connected to the connecting pipe through the three-way control valve. The powdered raw materials are then introduced into the conveying pipe groove. With the centrifugal force of the rotating drive shaft, the powder is stirred and mixed from the middle of the mixture in the mixing tank through the feeding hole. This allows the raw materials to fully contact the mixture and speeds up the mixing efficiency.

[0017] This invention uses a booster assembly to push powdered raw materials from the connection between the conveying pipe and the connecting pipe to the feed hole, which can ensure that the raw materials fully enter the mixing box to a certain extent.

[0018] This invention uses a three-way control valve to connect the circulating pump to the connecting pipe via a three-way pipe. Then, the circulating flushing component circulates the mixture in the mixing tank through the connecting pipe and the three-way pipe, thereby flushing the powder raw materials adhering to its inner wall and circulating them back into the mixing tank for stirring and mixing. This further ensures that the raw materials are fully incorporated into the mixing tank. Attached Figure Description

[0026] As attached Figure 1 To be continued Figure 4This utility model provides a high-efficiency mixing device for chemical raw materials, including a mixing tank 1. A support frame 2 is fixedly installed at the bottom of the mixing tank 1, and a feed inlet 3 is opened at the top of the mixing tank 1. A drive base 4 is fixedly installed on one side of the mixing tank 1 along its length. A drive shaft 5 is rotatably connected inside the mixing tank 1. A drive motor 6 capable of driving the drive shaft 5 is fixedly installed on the drive base 4. A stirring blade 7 is provided on the drive shaft 5. A feeding assembly 8 is provided on the mixing tank 1. The feeding assembly 8 includes feed holes 81 evenly opened on the drive shaft 5. The drive shaft 5 has a conveying pipe groove 82 that communicates with the feed hole 81. The drive shaft 5 is also rotatably connected to a connecting pipe 83 that communicates with the conveying pipe groove 82. The top of the connecting pipe 83 is fixedly connected to a three-way pipe 84. A three-way control valve 85 is installed on the three-way pipe 84. A material rack 86 is fixedly installed on the top of the mixing box 1. A feed hopper 87 is fixedly installed on the material rack 86. The bottom end of the feed hopper 87 is connected to the three-way pipe 84. A booster assembly 9 is provided on the other side of the mixing box 1 along its length. A circulation flushing assembly 10 is also connected to the three-way pipe 84.

[0027] Among them, the feed inlet 3 is the raw material addition port. The drive shaft 5 is driven to rotate by the drive motor 6, which can make the stirring blade 7 stir and mix the raw materials in the mixing box 1.

[0028] Specifically, during the stirring process of the stirring blade 7, powder raw materials are added to the feed hopper 87. The feed hopper 87 is connected to the connecting pipe 83 through the three-way control valve 85 via the three-way pipe 84, while the circulating pump 101 is not connected to the connecting pipe 83. The powder raw materials are introduced into the conveying pipe groove 82. With the centrifugal force of the rotating drive shaft 5, the powder is stirred and mixed from the middle of the mixture in the mixing tank 1 through the feed hole 81. At the same time, the booster component 9 can be used to convey the powder raw materials from the connection between the conveying pipe groove 82 and the connecting pipe 83 to the feed hole 81. Next, the circulating pump 101 is connected to the connecting pipe 83 through the three-way control valve 85 via the three-way pipe 84, while the feed hopper 87 is not connected to the connecting pipe 83. Then, the circulating flushing component 10 circulates the mixture in the mixing tank 1 through the connecting pipe 83 and the three-way pipe 84, so that the powder raw materials adhering to the inner wall are fully circulated into the mixing tank 1 for stirring and mixing.

[0029] Preferably, the top port of the connecting pipe 83 is higher than the top surface of the mixing tank 1 to prevent the mixture in the mixing tank 1 from flowing back out from the connecting pipe 83 and the feed hopper 87, and the three-way pipe 84 is fixedly installed on the top of the mixing tank 1.

[0030] Furthermore, the booster assembly 9 includes a second drive base 91, which is fixedly installed on the side of the mixing box 1 opposite to the first drive base 4. A booster motor 92 is fixedly installed on the second drive base 91, and a drive rod 93 is concentrically rotatably connected inside the drive shaft 5. The output end of the booster motor 92 is fixedly connected to one end of the drive rod 93, and a spiral auger 94 is provided on the drive rod 93.

[0031] Preferably, the drive shaft 5 and the drive rod 93 rotate in opposite directions, or the drive shaft 5 and the drive rod 93 rotate in the same direction with a speed difference.

[0032] The booster motor 92 drives the drive rod 93 to rotate, which in turn drives the auger 94 to transport the raw materials added in the feed hopper 87 to the feed hole 81, so as to ensure that the mixing is more thorough and uniform.

[0033] Preferably, the circulating flushing assembly 10 includes a circulating pump 101, the output end of which is connected to a three-way pipe 84, the input end of which is fixedly connected to a circulating pipe 102, and the end of the circulating pipe 102 away from the circulating pump 101 is fixedly connected to the mixing tank 1.

[0034] Specifically, the mixture in the mixing tank 1 can be circulated sequentially through the circulation pipe 102, the connecting pipe 83, the conveying pipe 82, the feed hole 81, and the mixing tank 1 by the circulation pump 101.

[0035] Preferably, a switch valve 103 is provided at one end of the circulation pipe 102 near the mixing tank 1. When no raw materials are added, the switch valve 103 closes the connection between the circulation pipe 102 and the mixing tank 1, thereby preventing the mixture from entering the circulation pipe 102.

[0036] Preferably, the three ports of the three-way pipe 84 correspond one-to-one with the connecting pipe 83, the feed hopper 87, and the circulating pump 101, and the three-way control valve 85 is used to control the connection or closure of the connecting pipe 83, the feed hopper 87, the circulating pump 101 and the three-way pipe 84.
