Description

Technical Field

[0001] This invention relates to the field of mixing device technology, specifically a suspension mixing device for the production of diuron wettable powder. Background Technology

[0002] Diuron is a long-acting, broad-spectrum, and low-toxicity herbicide suitable for weed control in crops such as cotton, rice, sugarcane, corn, pineapple, and fruit trees. Diuron wettable powder is one of the main raw materials for herbicides. In the production and preparation of diuron, its powder needs to be stirred to mix the materials. Therefore, the stirring device is one of the key pieces of equipment in the production and preparation of diuron.

[0003] In response, Chinese patent application number CN115121165A discloses a mixing device and method for producing diuron wettable powder. The device includes a quantitative dispensing mechanism, which comprises a fixed plate. Several material tanks are mounted on the upper end of the fixed plate (four tanks in total). An electric drive plate is mounted on the outside of each material tank. A quantitative pump is mounted on the lower end of each material tank, and a dispensing pipe is mounted on the lower end of the pump. This mixing device's quantitative dispensing mechanism automatically dispenses powder additives, diuron technical grade, and fillers. The dispensed powder is then conveyed by a screw conveyor and enters the mixing mechanism. The screw conveyor performs initial mixing of the materials, while the rotating mixing tanks perform secondary mixing, ensuring mixing quality. After mixing, diuron wettable powder is obtained. The solenoid valve opens, and the diuron wettable powder enters the grinding and filtering mechanism through the discharge pipe.

[0004] In response, Chinese patent application number CN208244621U discloses a noodle processing device, specifically a powder mixing device, including a frame, a mixing box mounted on the frame, a mixing rod installed inside the mixing box, a feed inlet on the mixing box, and a cover mounted on the frame for sealing the feed inlet. The mixing box is rotatably connected to the frame. Material enters the mixing box through the feed inlet for mixing, and is discharged through the feed inlet by tilting the mixing box. Using the same feed inlet for both feeding and discharging allows flour that has settled at the bottom to be further mixed during the discharge process, resulting in a more uniform mixture and eliminating dead zones. Furthermore, since there is no outlet at the bottom, the mixing rod can make more thorough contact with the bottom, making it easier to carry flour up and achieve more complete mixing.

[0005] A mixing device typically consists of a stirring system, a suspension system, a drive unit, and a control system. Suspension mixing devices are widely used in processes such as liquid mixing, dissolution reactions, or suspension of suspended matter in industries such as chemical, pharmaceutical, and food processing. In powder mixing, due to differences in particle size, shape, and density, the powder has poor flowability relative to the liquid. Therefore, a high-power drive unit is required for mixing. For example, mixing powders like diuron requires a relatively high-power drive unit to overcome friction and adhesion between the powder particles, which consumes a significant amount of energy, resulting in high energy consumption.

[0006] To address the aforementioned issues, a suspension mixing device for the production of diuron wettable powder is proposed. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0033] Combination Figures 1-7This invention discloses a suspension mixing device for producing diuron wettable powder, comprising a support base 1, an encapsulation chamber 56 mounted on the upper surface of the support base 1, a hydraulic push rod 2 fixedly connected to the upper surface of the encapsulation chamber 56, an output end of the hydraulic push rod 2 connected to a mounting frame 3, a positioning slide rod 4 provided at the top of the encapsulation chamber 56, and a drive assembly 5 provided at the top of the encapsulation chamber 56. In the production and preparation of diuron powder, the mixing device allows for more uniform mixing of materials. During the mixing of diuron, when the internal stirring rod is not rotating, the material cylinder 51 rotates, causing the cylinder to carry the material to impact the upper end of the stirring rod. This method also achieves material mixing. The specific operation is as follows:

[0034] The drive assembly 5 includes a mounting shaft 55. The top end of the package compartment 56 is connected to the mounting shaft 55, and the top end of the mounting shaft 55 is connected to a material cylinder 51. The material cylinder 51 is fixedly connected to the mounting shaft 55, and the bottom end of the mounting shaft 55 is rotatably connected to the support stand 1. A driven gear ring 52 is connected to the outer surface of the material cylinder 51. A drive motor 53 is embedded inside the support stand 1. The output end of the drive assembly 5 is connected to a drive gear 54. One side of the drive gear 54 meshes with the driven gear ring 52. Both the driven gear ring 52 and the drive gear 54 are embedded in the package compartment. Inside the packaging chamber 56, the bottom end of the material cylinder 51 is embedded in the packaging chamber 56 and rotates inside the packaging chamber 56. When the drive motor 53 starts working, it drives the drive gear 54 to rotate. Since the drive gear 54 and the driven gear ring 52 mesh with each other, the rotation of the drive gear 54 drives the rotation of the driven gear ring 52. The driven gear ring 52 and the material cylinder 51 are fixedly connected, thus forcing the material cylinder 51 to rotate inside the packaging chamber 56. When the material cylinder 51 rotates, it cooperates with the stirring assembly 8 to have a certain stirring effect.

[0035] A stirring assembly 8 is installed at the output end of the stirring motor 6. The stirring assembly 8 includes a mounting sleeve 81. The output end of the stirring motor 6 is connected to the mounting sleeve 81, which wraps around the output end of the stirring motor 6. Stirring blades 82 are evenly distributed on the surface of the mounting sleeve 81. The mounting sleeve 81 and the stirring blades 82 are movably connected by a hinge. The stirring blades 82 are designed as curved surfaces with one side bent. A return spring 83 is connected to the top of the stirring blades 82. The end of the return spring 83 away from the stirring blades 82 is connected to the mounting sleeve 81. When the stirring motor 6 drives the mounting sleeve 81 to rotate, the powder material inside is stirred and mixed by the stirring blades 82. The concave curved surface on one side of the stirring blades 82 is the working surface. The material is mixed by this surface. When stirring and mixing the powder material inside, the front limiting plate 84 supports one side of the stirring blades 82, restricting the position of the stirring blades 82 so that the stirring blades 82 can be better subjected to force.

[0036] A front limiting plate 84 is fixedly connected to the outer surface of the mounting sleeve 81, and a rear limiting plate 85 is also connected to the outer surface of the mounting sleeve 81. When the stirring blade 82 is not under force, the return spring 83 is in the reset state, and the front limiting plate 84 is attached to one side wall of the stirring blade 82. When the stirring blade 82 is under force, the other side wall of the stirring blade 82 is attached to the rear limiting plate 85. When it cooperates with the rotation of the material cylinder 51, the powder material can be pushed to a position away from the center of the material cylinder 51. The specific operation is as follows:

[0037] The rotation of the material cylinder 51 and the rotation of the stirring blade 82 do not occur simultaneously. The rotation directions of the material cylinder 51 and the stirring blade 82 are consistent, with counterclockwise rotation being the example. When the material cylinder 51 rotates, the powder material will move along the bottom wall of the material cylinder 51. When the material comes into contact with the outward protruding side of the stirring blade 82, which is an outer arc surface, the material will resist the stirring blade 82, causing the stirring blade 82 to be deflected to a certain degree. After the side wall of the stirring blade 82 touches the rear limiting plate 85, it can no longer deflect. Guided by the arc surface, the material can move outward along this surface, allowing the material to move away from the center of the material cylinder 51. In this way, the fluidity of the material is better in the later mixing process, and the mixing effect can also be improved to a certain extent.

[0038] The material cylinder 51 is embedded with a circulation component 7, which includes a blower 71. The blower 71 is embedded inside the material cylinder 51. An air guide groove 74 is opened inside the blower 71. A blower pipe 73 is installed on one side of the blower 71. The end of the blower pipe 73 is embedded in the air guide groove 74. An air outlet 75 is opened on the inner wall of the blower 71. The outer wall of the blower 71 is attached to the inner wall of the material cylinder 51. The air guide groove 74 inside the blower 71 is connected to the blower pipe 73 and the air outlet 75. A guide plate 76 is installed on the inner wall of the blower 71. The guide plate 76 corresponds one-to-one with the air outlet 75. The guide plate 76 is located on one side of the air outlet 75 and is inclined on the inner wall of the blower 71.

[0039] A stirring motor 6 is mounted on the bottom surface of the mounting frame 3. A sealing cap 72 covers the top of the blower 71. The output end of the stirring motor 6 passes through the interior of the sealing cap 72 and is embedded inside the blower 71. The sealing cap 72 and the blower 71 are connected by a screw thread, and a sealing gasket is filled at the connection between the sealing cap 72 and the blower 71. The covering of the blower 71 and the sealing cap 72 ensures an internal seal, preventing dust from overflowing during stirring.

[0040] In the stirring of powders, the powder itself has poorer flowability than liquids. Therefore, the load on the motor-driven stirring device is also greater. If the powder clumps together, the stirring will consume more power and energy.

[0041] To address the aforementioned issues, high-speed gas is introduced into the air guide trough 74 via the blower 73. After entering the air guide trough 74, the gas is finally discharged through the blower 75. The addition of high-speed gas agitates the powder inside, causing it to fly around. This, combined with the rotation of the stirring plate 82, mixes the powder. The flying powder contributes to the mixing process, and the reduced amount of powder in contact with the stirring plate 82 makes it easier to rotate. This reduces the load on the stirring motor 6, extending its service life. Powder mixing can be achieved with lower power and reduced energy consumption, resulting in a superior mixing effect compared to traditional stirring devices and lower energy consumption.

[0042] In order to reduce the load on the stirring motor 6, the gas discharged through the air outlet 75 will be blown obliquely into the material cylinder 51 along the guide plate 76. When the high-speed flowing gas is blown into the upper end of the stirring blade 82, it provides power for the rotation of the stirring blade 82, making the rotation of the stirring blade 82 easier. Thus, by making full use of kinetic energy, energy consumption is reduced and the stirring effect is improved.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
