Description

Technical Field

[0001] This utility model relates to the field of dispersion device technology, specifically a dispersion device for suspending agent production. Background Technology

[0002] Suspension concentrates are formulations in which solid pesticide active ingredients are uniformly dispersed in water as particles smaller than 4 micrometers. They are suspensions of solid pesticides and adjuvants that are difficult to dissolve in water, which are ground and dispersed in an aqueous medium. They do not cause dust problems like wettable powders, and are not flammable or explosive. They have small particle size, high biological activity, large specific gravity, and small packaging volume. They are relatively safe and environmentally friendly compared to other pesticide formulations, and are the largest tonnage pesticide varieties among the new water-based pesticide formulations. The existing patent authorization announcement number CN220478690U discloses a dispersion device for the production of suspension agents. By setting up a rotating block and a rectangular frame, the circular block at the right end of the rotating block can drive two sets of sliding rods to move up and down reciprocally through the rectangular frame. By setting up a connecting plate and a stirring rod, the two sets of sliding rods can move up and down reciprocally at the same time, so that the connecting plate drives the stirring rod to move up and down, thereby realizing the up and down movement of the screen plate, shaking the raw material in the screen plate to avoid clogging, and then discharging it evenly from the screen holes of the screen plate. In the aforementioned patent, the raw materials are shaken out by the up-and-down movement of the screen plate after entering the screen plate. However, some raw materials are clumped together and cannot be effectively shaken apart by the up-and-down movement of the screen plate. As a result, they tend to accumulate inside the screen plate, which is not easy to disperse and can affect the discharge speed, causing inconvenience to use. In addition, the screen plate obstructs the mixing tank, making it difficult to clean and maintain. Utility Model Content

[0003] The purpose of this invention is to provide a dispersion device for the production of suspension agents, in order to solve the problem in the above-mentioned background technology that some raw materials are clumped together and cannot be effectively dispersed as the screen moves up and down, thus easily accumulating inside the screen, which is not convenient for dispersion and can affect the discharge speed, causing inconvenience to use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a dispersion device for producing suspension concentrate, comprising a mixing tank and a top cover disposed on the top of the mixing tank, a feeding cylinder fixedly installed on the top of the top cover, a dispersion component and a mixing component arranged vertically inside the mixing tank, and a locking component disposed on the outer side wall of the mixing tank; the dispersion component includes a support frame fixedly installed on the top of the top cover, a drive motor fixedly installed on the top of the support frame, a rotating shaft extending downward into the mixing tank fixedly installed outside the output shaft of the drive motor, a receiving plate fixedly installed at the lower end of the rotating shaft, an impact plate fixedly connected in an annular shape at equal intervals on the top of the receiving plate, an impact ring adapted to the height of the receiving plate fixedly installed on the inner side wall of the mixing tank, protrusions fixedly connected in an annular shape at equal intervals on the inner side wall of the impact ring, and through holes opened in an annular shape at equal intervals on the top of the receiving plate.

[0005] Preferably, the receiving plate is conical in shape, and the striking plate is vertically positioned at the top of the receiving plate.

[0006] Preferably, the striking plate and the through hole are offset, and the top edge of the striking plate is chamfered.

[0007] Preferably, the protrusion has a pyramidal structure facing the receiving plate, and the protrusion is located inside the impact ring and is equidistant from top to bottom.

[0008] Preferably, the feeding cylinder extends into the interior of the mixing tank, and the rotating shaft is arranged on the same axis as the feeding cylinder.

[0009] Preferably, the engaging assembly includes two support sleeves fixedly connected to the left and right outer walls of the mixing tank. Each of the two support sleeves has a mounting hole with a top opening. A telescopic electric cylinder with its telescopic end facing upward is fixedly installed inside each mounting hole. A support block is fixedly connected to the top of the mounting hole, and the support block is fixedly connected to the outer wall of the top cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The drive motor drives the rotating shaft to rotate, which in turn drives the receiving plate to rotate rapidly. The raw material falls and impacts the receiving plate and is dispersed. Due to the rotation of the receiving plate, the raw material is hit and dispersed by the impact plate. The centrifugal force generated by the rotation of the receiving plate causes the raw material to be thrown outward. Some of the clumps of raw material that are not dispersed are thrown onto the inner wall of the impact ring. The clumps collide with the protrusions and are dispersed into smaller particles that fall quickly into the mixing tank, thereby achieving efficient feeding and dispersion of raw materials and ensuring a smooth feeding process. 2. By controlling the telescopic electric cylinders in the left and right support sleeves to extend synchronously, the telescopic electric cylinders push the support block, thereby driving the top cover to move the feeding cylinder and receiving plate upward out of the mixing tank, opening the top of the mixing tank, which facilitates the use of water pipes to clean the mixing tank, dispersing components and mixing components, improving the convenience of maintenance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a dispersion device for producing a suspension agent, comprising a mixing tank 1 and a top cover 2 disposed on the top of the mixing tank 1. A feeding cylinder 3 is fixedly installed on the top of the top cover 2. A dispersion component 4 and a mixing component 6 are disposed vertically inside the mixing tank 1. A locking component 5 is disposed on the outer side wall of the mixing tank 1. The dispersion component 4 includes a support frame 41 fixedly installed on the top of the top cover 2. A drive motor 42 is fixedly installed on the top of the support frame 41. A rotating shaft 43 extending downward into the mixing tank 1 is fixedly installed outside the output shaft of the drive motor 42. A receiving plate 44 is fixedly installed at the lower end of the rotating shaft 43. A striking plate 45 is fixedly connected in a ring at equal intervals on the top of the receiving plate 44. A series of components are fixedly installed on the inner side wall of the mixing tank 1. The receiving plate 44 is fitted with an impact ring 46 of the same height. The inner wall of the impact ring 46 is fixedly connected with protrusions 47 in an annular pattern. The top of the receiving plate 44 is provided with through holes 48 in an annular pattern. The drive motor 42 drives the rotating shaft 43 to rotate, which in turn drives the receiving plate 44 to rotate rapidly. The raw material falls and impacts the receiving plate 44 and is dispersed. Some of the raw material can fall into the bottom of the mixing tank 1 along the through holes 48. The remaining raw material is further dispersed by the impact plate 45 due to the rotation of the receiving plate 44. The centrifugal force generated by the rotation of the receiving plate 44 causes the raw material to be thrown outward. Some of the raw material that is not dispersed is thrown onto the inner wall of the impact ring 46. The clumps of raw material are subjected to a large impact force and collide with the protrusions 47, and are dispersed again, thereby achieving efficient feeding and dispersion of raw materials and ensuring a smooth feeding process.

[0017] The receiving plate 44 is conical in shape, and the striking plate 45 is vertically mounted on the top of the receiving plate 44. Its inclined conical surface design can guide the falling raw material to slide towards the edge, forming an efficient cooperation with the vertically mounted striking plate 45, making it easier for the raw material to be struck and dispersed during the sliding process. At the same time, the conical structure can reduce the accumulation of raw material on the surface of the receiving plate 44, ensuring that the through hole 48 is not easily blocked, further improving the efficiency of raw material falling and dispersion, and making the entire feeding and dispersion process smoother and more efficient.

[0018] The striking plate 45 and the through hole 48 are staggered. The top edge of the striking plate 45 is chamfered to avoid the striking plate 45 blocking the through hole 48. This ensures that after the raw material is struck by the striking plate 45, some of the powdery raw material can fall smoothly through the through hole 48, preventing the raw material from accumulating on the receiving plate 44 due to obstruction. The chamfered design of the top edge of the striking plate 45 makes it easier for the raw material to concentrate the force point and disperse when it comes into contact with the striking plate 45, improving the uniformity of raw material dispersion and the stability of feeding.

[0019] The protrusion 47 is a pyramidal structure facing the receiving plate 44. The protrusion 47 is located inside the impact ring 46 and is equidistant from top to bottom. Its sharp pyramidal tip can accurately impact the thrown blocky raw material, further breaking the agglomerated raw material into fine particles. The side tilt angle of the pyramidal structure is optimized so that it can guide the broken raw material to disperse in all directions after impact, reducing the residence time of the raw material in the impact ring 46. This allows the dispersed raw material to fall more quickly through the gap between the impact ring 46 and the receiving plate 44, forming a progressive dispersion effect with the impact of the receiving plate 44, further improving the overall dispersion device's ability to refine the raw material.

[0020] The feeding cylinder 3 extends into the interior of the mixing tank 1. The rotating shaft 43 is set on the same axis as the feeding cylinder 3. The bottom of the rotating shaft 43 is fixedly connected to the center of the receiving plate 44, ensuring that when the rotating shaft 43 drives the receiving plate 44 to rotate, the entire dispersion component 4 can maintain a stable coaxial rotation around the central axis of the feeding cylinder 3. The coaxial design allows the raw materials falling from the feeding cylinder 3 to fall accurately into the area of ​​the receiving plate 44, avoiding uneven distribution of raw materials due to eccentricity, which would affect the dispersion effect.

[0021] The mixing component 6 includes a crossbeam 61 fixedly installed on the inner wall of the mixing tank 1. The crossbeam 61 is located below the dispersing component 4. A rotating shaft 62 with its end penetrating the side wall of the mixing tank 1 is rotatably installed inside the crossbeam 61. A drive motor 63 connected to the rotating shaft 62 is fixedly installed on the outer wall of the mixing tank 1. An agitator 64 is rotatably installed at the center of the bottom of the crossbeam 61. The drive motor 63 and the agitator 64 are connected by gear transmission. Agitator blades 65 are fixedly installed longitudinally and equidistantly on the outside of the agitator 64. When the raw material falls into the lower part of the mixing tank 1, the drive motor 63 drives the rotating shaft 62 to rotate. Right-angle transmission is achieved by the bevel gears that mesh with each other and are installed at the adjacent end of the rotating shaft 62 and the agitator 64 inside the crossbeam 61, thereby driving the agitator 64 to rotate. The agitator 64 drives the agitator blades 65 to rotate, thus mixing the raw material.

[0022] Please see Figure 1 and Figure 5The locking assembly 5 includes two support sleeves 51 fixedly connected to the left and right outer walls of the mixing tank 1. Each support sleeve 51 has a top-opening mounting hole 52. A telescopic electric cylinder 53 with its telescopic end facing upward is fixedly installed inside each mounting hole 52. A support block 54 is fixedly connected to the top of the mounting hole 52. The support block 54 is fixedly connected to the outer wall of the top cover 2. When it is necessary to clean the residual material in the mixing tank 1, the telescopic electric cylinders 53 in the left and right support sleeves 51 are controlled to extend synchronously. The telescopic electric cylinders 53 push the support block 54, thereby driving the top cover 2 to move the feeding cylinder 3 and the receiving plate 44 upward out of the mixing tank 1, opening the top of the mixing tank 1. This makes it easier to use a water pipe to clean the mixing tank 1, the dispersing component 4 and the mixing component 6, improving the convenience of maintenance.

[0023] The top of the mixing tank 1 is provided with a locking groove 11 that is adapted to the top cover 2. A sealing ring 12 is movably engaged inside the locking groove 11. When the top cover 2 is closed on the top of the mixing tank 1, the sealing ring 12 can form a tight sealing structure between the top cover 2 and the locking groove 11, ensuring the sealing and cleanliness of the suspension production process.

[0024] Working principle: During use, the drive motor 42 drives the rotating shaft 43 to rotate, which in turn drives the receiving plate 44 to rotate rapidly. The raw material is fed into the mixing tank 1 from above the feeding cylinder 3. The raw material falls onto the receiving plate 44 and is dispersed by the impact. Some of the raw material can fall into the lower part of the mixing tank 1 through the through hole 48. The remaining raw material is thrown outward by the centrifugal effect generated by the rotation of the receiving plate 44 and falls into the lower part of the mixing tank 1 through the space between the receiving plate 44 and the impact ring 46. During the process of throwing the raw material outward, some of the raw material that was not dispersed is thrown onto the inner wall of the impact ring 46. The clumps of raw material are subjected to a large force to impact the protrusion 47. The pyramidal protrusion 47 can completely disperse the clumps of raw material and then disperse them into the mixing tank 1. This can ensure efficient feeding and dispersion of raw materials and ensure smooth feeding. The raw materials are scattered into the lower part of the mixing tank 1. The drive motor 63 drives the rotating shaft 62 to rotate. The rotating shaft 62 and the stirring rod 64 are driven by a bevel gear that meshes with each other in the cross frame 61 at their adjacent ends. This drives the stirring rod 64 to rotate, and the stirring blade 65 rotates to stir and mix the raw materials. The material is then discharged by opening the valve on the discharge port at the bottom of the mixing tank 1. When it is necessary to clean the residual material in the mixing tank 1, the telescopic electric cylinders 53 in the left and right support sleeves 51 are controlled to extend synchronously. The telescopic electric cylinders 53 push the support block 54, which in turn pushes the top cover 2, causing the feeding cylinder 3 and the receiving plate 44 to move upward and out of the mixing tank 1, so that the top of the mixing tank 1 is open. This makes it convenient to use water pipes to clean the mixing tank 1, the dispersing component 4 and the mixing component 6, improving the convenience of maintenance. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
