Description

Technical Field

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

[0002] A mixer is a widely used piece of equipment in industrial production. It uses mechanical means to force materials to circulate in a container to achieve mixing, homogenization, dispersion, and dissolution. However, in existing mixers, a ring of powder residue remains at the lower part of the joint between the discharge assembly and the cylinder after each use. This reduces the mixer's production efficiency and also makes cleaning and maintenance inconvenient. Utility Model Content

[0003] This invention provides a mixer to solve the defect of material powder residue in the prior art. By limiting the distance between the first discharge port and the cylinder axis to between 0.2 and 0.3 times the cylinder diameter, the contact point between the discharge component and the lower side of the cylinder can be moved inward. This allows the cylinder to discharge as much material as possible into the cylinder, reducing the problem of powder residue at the junction of the discharge component and the bottom of the cylinder, and facilitating the cleaning and maintenance of the mixer in the later stages.

[0004] The mixer provided by this utility model includes:

[0005] The cylinder body has a first discharge port at the bottom;

[0006] A stirring assembly is installed inside the cylinder.

[0007] A discharge assembly is provided at the first discharge port, and the discharge assembly is used for unloading materials;

[0008] The diameter of the cylinder is D, and the distance between the first discharge port and the axis of the cylinder is a, wherein the value of a ranges from 0.2D to a and from 0.3D to 0.3D.

[0009] According to the mixer provided by this utility model, a is 0.25D.

[0010] According to the mixer provided by this utility model, the included angle between the axis of the unloading assembly and the axis of the cylinder is b, wherein the value of b is in the range of 72°≤b≤74°.

[0011] According to the mixer provided by this utility model, b is 73°.

[0012] According to the mixer provided by this utility model, the unloading assembly includes a first discharge barrel, a second discharge barrel, a third discharge barrel, and a piston component. One end of the first discharge barrel is located at the first discharge port, and the other end is connected to the second discharge barrel. The side wall of the second discharge barrel is provided with a second discharge port. The third discharge barrel is located at the second discharge port. The piston component passes through the second discharge barrel and is adapted to perform linear reciprocating motion along the barrel cavity of the second discharge barrel. When the mixer is in the feeding or mixing state, the piston component is used to disconnect the communication between the first discharge barrel and the third discharge barrel.

[0013] According to the mixer provided by this utility model, the piston component includes:

[0014] A piston is located inside the second discharge bucket and is adapted to reciprocate linearly along the cavity of the second discharge bucket. When the mixer is feeding or stirring, the piston is used to disconnect the communication between the first discharge bucket and the third discharge bucket.

[0015] A drive cylinder, connected to the piston, is used to drive the piston to perform linear reciprocating motion;

[0016] A guide rod is located on the side of the piston away from the first discharge barrel and slides in cooperation with the second discharge barrel. The guide rod is used to limit the movement direction of the piston.

[0017] According to the mixer provided by this utility model, the second discharge hopper is provided with an observation window, and the unloading assembly also includes a window cover corresponding to the observation window.

[0018] According to the mixer provided by this utility model, the bottom of the cylinder has an arc surface, and the arc surface is bent toward the mixing assembly.

[0019] According to the mixer provided by this utility model, the mixing assembly includes a drive motor and a mixing component. The mixing component is inserted through the cylinder and is coaxial with the cylinder. The drive motor is connected to the mixing component and is used to drive the mixing component to rotate.

[0020] According to the mixer provided by this utility model, the mixing component includes a mixing shaft and a fan blade. The mixing shaft is connected to the drive motor and rotates with the cylinder. The fan blade is disposed on the mixing shaft, and the shape of the fan blade is adapted to the shape of the arc surface.

[0021] The mixer provided by this utility model limits the distance between the first discharge port and the cylinder axis to between 0.2 and 0.3 times the cylinder diameter. Compared with the mixers in the prior art, this allows the contact point between the discharge component and the lower side of the cylinder to be moved inward, making the contact point closer to the cylinder axis. In this way, during the discharge process, the cylinder can discharge as much material as possible into the cylinder, which can improve the discharge efficiency and reduce the problem of powder residue at the junction of the discharge component and the bottom of the cylinder, which is helpful for the later cleaning and maintenance of the mixer.

[0031] Figure 1 This is a schematic diagram of the structure of the mixer provided in one embodiment of the present invention; Figure 2 This is a schematic diagram of the mixer provided in another embodiment of the present invention.

[0032] See Figure 1 and Figure 2 This utility model provides a mixer, which includes a cylinder 100, a mixing component 200, and a discharge component 300. The bottom of the cylinder 100 is provided with a first discharge port 110, and the discharge component 300 is disposed at the first discharge port 110. In other words, the discharge component 300 is connected to the first discharge port 110 and is used for discharging material. The mixing component 200 is inserted into the cylinder 100 and is used for mixing materials.

[0033] The diameter of the cylinder 100 is D, and the distance between the first discharge port 110 and the axis of the cylinder 100 is a, where the value of a ranges from 0.2D to a and from 0.3D to 0.3D.

[0034] In one specific embodiment, assuming the diameter of the cylinder 100 is 747 mm, then the value of 'a' in this embodiment ranges from 149.4 mm to 224.1 mm. (See reference...) Figure 1 It is understood that the mixer provided in this embodiment of the present invention, by limiting the distance between the first discharge port 110 and the axis of the cylinder 100 to between 0.2 times and 0.3 times the diameter of the cylinder 100, compared with the mixer in the prior art, can move the contact point between the unloading component 300 and the lower side of the cylinder 100 inward, that is, make the contact point closer to the axis of the cylinder 100. In this way, during the unloading process, the cylinder 100 can discharge as much material as possible into the cylinder 100, which can improve the unloading efficiency and reduce the problem of powder residue at the junction of the unloading component 300 and the bottom of the cylinder 100, which is helpful for the cleaning and maintenance of the mixer in the later stage.

[0035] Continue reading Figure 1 In the embodiments of this utility model, the aforementioned a is 0.25D. In a specific embodiment, assuming the diameter of the cylinder 100 is 747mm, then in this embodiment, the value of a is 187mm. After multiple experimental verifications, limiting the distance between the first discharge port 110 and the cylinder 100 to 0.25 times the diameter of the cylinder 100 can minimize the amount of powder residue between the unloading component 300 and the bottom of the cylinder 100 while ensuring that the first discharge port 110 and the stirring component 200 do not interfere with each other.

[0036] Continue reading Figure 1 In an optional embodiment of this utility model, the angle between the axis of the unloading assembly 300 and the axis of the cylinder 100 is b, wherein the value of b is in the range of 72°≤b≤74°, and preferably b is 73°.

[0037] Understandably, limiting the angle between the axis of the unloading assembly 300 and the axis of the cylinder 100 to the above-mentioned range allows the unloading assembly 300 to have a greater inclination relative to the vertical plane compared to the prior art, thus making the unloading process smoother.

[0038] Continue reading Figure 1In an optional embodiment of this utility model, the unloading assembly 300 includes a first discharge barrel 310, a second discharge barrel 320, a third discharge barrel 330, and a piston component 340. One end of the first discharge barrel 310 is located at the first discharge port 110, and the other end is connected to the second discharge barrel 320. The side wall of the second discharge barrel 320 is located at the second discharge port 370. The third discharge barrel 330 is located at the second discharge port 370. The piston component 340 passes through the second discharge barrel 320 and is adapted to perform linear reciprocating motion along the barrel cavity of the second discharge barrel 320. When the mixer is feeding or stirring, the piston component 340 is used to isolate the communication between the first discharge barrel 310 and the third discharge barrel 330.

[0039] See Figure 1 Understandably, during use, when the mixer needs to feed or perform mixing operations, the piston component 340 blocks the first discharge port 110, ensuring the bottom of the cylinder 100 remains intact and preventing material leakage. The piston component 340 has strong stability, ensuring the sealing of the first discharge port 110. During unloading, the piston component 340 moves along the cavity of the second discharge barrel 320 in a direction away from the first discharge barrel 310, connecting the first discharge barrel 310 and the second discharge barrel 320. As the piston component 340 continues to move, the second discharge port 370 on the second discharge barrel 320 connects with the first discharge barrel 310, thereby connecting the third discharge barrel 330 with the first discharge barrel 310, achieving unloading.

[0040] Continue reading Figure 1 In an optional embodiment of this utility model, the piston component 340 includes a piston 341, a drive cylinder 342, and a guide rod 343. The piston 341 is located inside the second discharge barrel 320 and is adapted to perform linear reciprocating motion along the barrel cavity of the second discharge barrel 320. When the mixer is feeding or stirring, the piston 341 is used to disconnect the communication between the first discharge barrel 310 and the third discharge barrel 330. The drive cylinder 342 is connected to the piston 341 and is used to drive the piston 341 to perform linear reciprocating motion. The drive cylinder 342 can be an existing product such as a pneumatic cylinder or an electric cylinder. The guide rod 343 is located on the side of the piston 341 away from the first discharge barrel 310 and slides in cooperation with the end of the second discharge barrel 320. The second discharge barrel 320 can restrict the radial movement of the guide rod 343, thereby allowing the guide rod 343 to restrict the movement direction of the piston 341.

[0041] Understandably, the drive cylinder 342 has a smooth and stable power output and a strong load capacity. During the mixing or feeding process of the mixer, the drive cylinder 342 can ensure the closure of the bottom of the cylinder 100, which can avoid problems such as material leakage. In addition, the guide rod 343 can further improve the stability of the piston component 340 and reduce the risk of damage to the piston component 340 due to excessive discharge impact force.

[0042] Continue reading Figure 1 In an optional embodiment of this utility model, the second discharge hopper 320 is provided with an observation window 350, and the unloading assembly 300 includes a window cover 360 corresponding to the observation window 350. During the unloading process, the operator can observe the unloading situation inside the unloading assembly 300 through the observation window 350, thereby controlling the unloading progress. In addition, if the unloading assembly 300 is blocked, it can be cleared through the observation window 350. That is, the observation window 350 helps in the maintenance of the mixer.

[0043] Continue reading Figure 1 In an optional embodiment of this utility model, the bottom of the cylinder 100 has an arc surface 120, which is arranged around the bottom of the cylinder 100 and is curved toward the stirring assembly 200. It can be understood that the arc surface 120 helps the material to gather at the bottom of the cylinder 100, which can improve the stirring efficiency of the stirring assembly 200. In addition, the arc surface 120 has no sharp edges, which makes it easier to clean the cylinder 100 and reduces the space for dirt to accumulate.

[0044] Continue reading Figure 2 In an optional embodiment of this utility model, the stirring assembly 200 includes a drive motor 210 and a stirring component 220. The stirring component 220 is disposed inside the cylinder 100 and coaxial with the cylinder 100. The drive motor 210 is connected to the stirring component 220 and is used to drive the stirring component 220 to rotate. (Continue reading) Figure 2 In an optional embodiment of this utility model, the stirring component 220 includes a stirring shaft 221 and a fan blade 222. The stirring shaft 221 is connected to the output end of the drive motor 210 and rotates with the cylinder 100. The fan blade 222 is disposed on the stirring shaft 221. The shape of the fan blade 222 is adapted to the shape of the arc surface 120. It can be understood that this design can make the gap between the fan blade 222 and the cylinder 100 smaller, can make the contact between the fan blade 222 and the material more sufficient, and can make the stirring efficiency higher.

[0045] It should be noted that the technical solutions in the various embodiments of this utility model can be combined with each other, but the basis for such combination is that they can be implemented by those skilled in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist, that is, it is not within the protection scope of this utility model.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
