Description

Technical Field

[0001] This utility model relates to the field of suspension production technology, specifically to a sand mill device for suspension production. Background Technology

[0002] Suspension concentrates, also known as concentrated suspensions, flow agents, water suspensions, or colloidal suspensions, are stable suspension systems formed by uniformly dispersing water-insoluble solid pesticide active ingredients in water using surfactants (such as wetting agents and dispersants). They appear as a suspension and can be diluted with water to form a uniform suspension for spraying. In the production of suspension concentrates, the active ingredient is usually a solid particle that is poorly soluble in water. To ensure good dispersion and stability in water, these particles must be ground to a very fine size, requiring a sand mill. A sand mill (also called a bead mill) is a high-efficiency grinding device mainly used for ultrafine pulverization and dispersion of solid particles in a liquid medium. Its principle is that a high-speed rotating rotor drives the grinding media (such as zirconia beads, glass beads, etc.) to move within the grinding chamber, pulverizing the material through collision and shearing between the media. The use of a sand mill can achieve the micronization of solid active ingredients, promote uniform dispersion of solid active ingredients in a liquid medium, thereby improving the stability and suspension rate of the suspension concentrate, and enhancing product quality and efficacy.

[0003] When pulverizing suspension raw materials using a sand mill, the raw materials may not be uniform or sufficiently pulverized, which makes it difficult to ensure the complete uniformity of the raw material particle size. Furthermore, existing technologies cannot effectively screen the pulverized suspension raw materials, making it inconvenient to classify the suspension and failing to ensure the uniformity of the suspension quality. Therefore, in order to solve the above problems, a sand mill device for suspension production is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a sand milling device for producing suspensions, so as to solve the problem mentioned in the background art that it is not possible to screen the pulverized suspension raw materials well, making it inconvenient to classify the suspensions and not to ensure the uniformity of the suspension quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sand milling device for producing suspension agents, comprising a support frame, a sand milling cylinder movably connected to the inner side of the support frame, a feed inlet fixedly connected to the top of the sand milling cylinder, a discharge pipe fixedly connected to the bottom of the sand milling cylinder, a rotating rod movably connected to the inner side of the sand milling cylinder, and a dispersing disc fixedly connected to the surface of the rotating rod.

[0006] The bottom end of the grinding cylinder is provided with a screening mechanism, and the surface of the support frame is provided with a rotating mechanism.

[0007] The screening mechanism includes a screening box, which is fixedly connected to the bottom end of the discharge pipe, and a first fixing rod is fixedly connected to the inner wall of the screening box, and a screen plate is movably connected to the surface of the first fixing rod.

[0008] The rotating mechanism includes a second fixed rod, which is fixedly connected to the top of the grinding cylinder, and a third conical tooth is fixedly connected to the top of the second fixed rod. The rotating rod moves inside the second fixed rod and the third conical tooth.

[0009] Preferably, the screening mechanism further includes a first discharge port, which is located inside the screening box, and a second discharge port is located inside the screening box. The screen plate is movable inside the first discharge port, and a connecting rod is fixedly connected to the surface of the screen plate, and the connecting rod is movable inside the screening box.

[0010] Preferably, a fixing block is fixedly connected to the surface of the screening box, and a first rotating rod is movably connected to the inner side of the fixing block, with a cam fixedly connected to the top end of the first rotating rod.

[0011] Preferably, a first motor is fixedly installed at the bottom of the fixed block, and the end of the first rotating rod away from the cam is fixedly connected to the output end of the first motor. A spring is fixedly connected to the surface of the screen plate, and one end of the spring is fixedly connected to the screening box, while the other end of the spring is fixedly connected to the screen plate.

[0012] Preferably, the rotating mechanism further includes a support plate, which is fixedly connected to the upper surface of the support frame, and a second rotating rod is movably connected to the inner side of the support plate. A first conical tooth is fixedly connected to the surface of the second rotating rod, and a second motor is fixedly installed on the surface of the support plate.

[0013] Preferably, the end of the second rotating rod away from the first conical tooth is fixedly connected to the output end of the second motor, the top end of the rotating rod is fixedly connected to the second conical tooth, and the surface of the grinding cylinder is fixedly connected to a connecting ring.

[0014] Preferably, the inner side of the support frame is provided with a movable groove, and the end of the connecting ring away from the grinding cylinder is movable inside the movable groove.

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

[0016] 1. The sieve plate allows for the screening of pulverized suspension raw materials, facilitating material classification and ensuring their quality and uniformity. This, in turn, facilitates better suspension production. Simultaneously, the first rotating rod drives the cam to rotate, causing it to press against the connecting rod, thus moving the sieve plate. Combined with the spring mechanism, this allows the sieve plate to reciprocate and vibrate, accelerating the screening of raw materials and reducing the risk of clogging due to material accumulation. This ensures the quality and effectiveness of raw material screening.

[0017] 2. The first conical tooth is rotated by the second rotating rod, which in turn drives the second and third conical teeth to rotate. This causes the rotating rod to drive the dispersing disc to rotate, and the second fixed rod to drive the grinding cylinder to rotate. The rotation direction of the grinding cylinder is opposite to that of the rotating rod. This allows the grinding cylinder to rotate in the opposite direction while the dispersing disc is stirring and crushing the suspending agent raw material. This increases the impact and collision of the raw material within the grinding cylinder, resulting in a better crushing effect. Attached Figure Description

[0024] 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.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] The first motor 29 and the second motor 33 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0027] A sand milling device for producing a suspension concentrate includes a support frame 1. A sand mill cylinder 11 is movably connected to the inner side of the support frame 1. A feed inlet 12 is fixedly connected to the top of the sand mill cylinder 11. A discharge pipe 13 is fixedly connected to the bottom of the sand mill cylinder 11. A rotating rod 14 is movably connected to the inner side of the sand mill cylinder 11. A dispersing disc 15 is fixedly connected to the surface of the rotating rod 14. A screening mechanism is provided at the bottom of the sand mill cylinder 11. A rotating mechanism is provided on the surface of the support frame 1. The screening mechanism includes a screening box 2, which is fixedly connected to the bottom of the discharge pipe 13. A first fixing rod 21 is fixedly connected to the inner wall of the screening box 2. The surface is movably connected to a sieve plate 22. The rotating mechanism includes a second fixed rod 35, which is fixedly connected to the top of the grinding cylinder 11. A third conical tooth 36 is fixedly connected to the top of the second fixed rod 35. The rotating rod 14 moves inside the second fixed rod 35 and the third conical tooth 36. The feed inlet 12 allows the suspension raw material to enter the grinding cylinder 11 through the feed inlet 12. The rotating rod 14 drives the dispersing disc 15 to rotate. With the action of grinding media such as zirconia beads and glass beads, the suspension raw material can be impacted, rubbed, and sheared, thereby achieving the grinding and crushing of the suspension.

[0028] Furthermore, the screening mechanism also includes a first discharge port 23, which is located inside the screening box 2. A second discharge port 24 is located inside the screening box 2. The screen plate 22 is movable inside the first discharge port 23. A connecting rod 25 is fixedly connected to the surface of the screen plate 22, and the connecting rod 25 is movable inside the screening box 2. By setting the screen plate 22, the processed suspension raw materials can be screened, which facilitates the classification of suspension raw materials and ensures the quality of the suspension after crushing.

[0029] Furthermore, a fixing block 26 is fixedly connected to the surface of the screening box 2, and a first rotating rod 27 is movably connected to the inner side of the fixing block 26. A cam 28 is fixedly connected to the top of the first rotating rod 27. By setting the cam 28, the first rotating rod 27 drives the cam 28 to rotate, which can realize the cam 28 pressing the connecting rod 25. This facilitates the connecting rod 25 to drive the screen plate 22 to move under the action of the cam 28. With the setting of the spring 210, the screen plate 22 can reciprocate. Thus, the screen plate 22 shakes, which can accelerate the screening of the suspension raw material.

[0030] Furthermore, a first motor 29 is fixedly installed at the bottom of the fixed block 26, and the end of the first rotating rod 27 away from the cam 28 is fixedly connected to the output end of the first motor 29. A spring 210 is fixedly connected to the surface of the screen plate 22, and one end of the spring 210 is fixedly connected to the screening box 2, and the other end of the spring 210 is fixedly connected to the screen plate 22. Through the setting of the spring 210, when the cam 28 releases the pressure on the connecting rod 25, the screen plate 22 can be reset under the rebound action of the spring 210. In turn, in conjunction with the action of the cam 28, the screen plate 22 can shake and vibrate in the screening box 2, thereby accelerating the separation of raw materials.

[0031] Furthermore, the rotating mechanism also includes a support plate 3, which is fixedly connected to the upper surface of the support frame 1. A second rotating rod 31 is movably connected to the inner side of the support plate 3. A first conical tooth 32 is fixedly connected to the surface of the second rotating rod 31. A second motor 33 is fixedly installed on the surface of the support plate 3. The first conical tooth 32 is rotated by the second rotating rod 31, so that the rotation of the first conical tooth 32 can realize the transmission of the second conical tooth 34 and the third conical tooth 36. This facilitates the rotation of the rotating rod 14 and the second fixed rod 35, so that the grinding cylinder 11 can rotate in the opposite direction to the rotating rod 14. This allows the suspension raw material to have better impact and collision in the grinding cylinder 11, resulting in better crushing effect.

[0032] Furthermore, the end of the second rotating rod 31 away from the first conical tooth 32 is fixedly connected to the output end of the second motor 33, and the top of the rotating rod 14 is fixedly connected to the second conical tooth 34. The surface of the grinding cylinder 11 is fixedly connected to the connecting ring 37. Through the setting of the second conical tooth 34, the rotation of the first conical tooth 32 can realize the transmission of the second conical tooth 34, thereby facilitating the rotating rod 14 to drive the dispersing disk 15 to rotate, thereby realizing the grinding and crushing of the suspension raw material.

[0033] Furthermore, the inner side of the support frame 1 is provided with a movable groove 38, and the end of the connecting ring 37 away from the grinding cylinder 11 moves inside the movable groove 38. By setting the connecting ring 37 in conjunction with opening the movable groove 38, the rotation of the grinding cylinder 11 in the support frame 1 can be limited, which can ensure the stability of the rotation of the grinding cylinder 11.

[0034] Working principle: During use, the screen plate 22 is set to screen the crushed suspension raw materials, so that the raw materials can be discharged through the first discharge port 23 and the second discharge port 24 respectively. The first motor 29 is electrically connected to an external power source. The operator starts the first motor 29 by pressing the switch. The first motor 29 drives the first rotating rod 27 to rotate. The cam 28 will rotate under the action of the first rotating rod 27. When the cam 28 rotates, it squeezes the connecting rod 25, so that the connecting rod 25 moves inside the screening box 2, and the screen plate 22 moves on the surface of the first fixed rod 21 and inside the first discharge port 23. At this time, the spring 210 deforms. When the cam 28 releases the squeeze on the connecting rod 25 during the rotation, the screen plate 22 is reset under the rebound action of the spring 210. Then, through the cooperation of the cam 28 and the spring 210, the screen plate 22 reciprocates and shakes, thereby accelerating screening and preventing blockage.

[0035] The second motor 33 is electrically connected to an external power source. The operator starts the second motor 33 by pressing a switch. The operation of the second motor 33 drives the second rotating rod 31 to rotate. The first conical tooth 32 rotates under the action of the second rotating rod 31, and realizes the transmission of the second conical tooth 34 and the third conical tooth 36. Then, the rotating rod 14 drives the dispersion disc 15 to rotate under the action of the second conical tooth 34, realizing the dispersion of the suspending agent raw material. The rotation of the third conical tooth 36 causes the second fixed rod 35 to drive the sand mill 11 to rotate, thereby realizing the movement of the sand mill 11 within the support frame 1, and causing the connecting ring 37 to rotate inside the movable groove 38. This makes the rotation direction of the sand mill 11 opposite to the rotation direction of the rotating rod 14, so that the raw material can be better impacted and collided within the sand mill 11, thereby enhancing the crushing effect.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
