Description

Technical Field

[0001] This application relates to the technical field of mixing equipment, and more specifically, to a mixing device for the production of fungicides. Background Art

[0002] During the production of fungicides, it is often necessary to mix and stir raw materials. Therefore, fungicide mixing tanks are commonly used equipment in the fungicide production process.

[0003] In this regard, Chinese Patent Application No. CN202320263503.2 discloses a raw material mixing device for the preparation of fungicides. This solution mainly uses a screw feeder to lift the materials deposited at the bottom of the mixing chamber back into the mixing chamber for re-mixing and stirring, avoiding the blind area of the stirring shaft, making the mixing of pharmaceutical raw materials more uniform and having a high mixing efficiency.

[0004] However, during the process of implementing the technical solutions in the embodiments of this application by the utility model applicant of this application, it is found that the above technology has at least the following technical problems:

[0005] The above solution uses two screw rods to achieve discharging and circulating stirring, with too many dead corners to clean and being not easy to clean. Summary of the Utility Model

[0006] To make up for the above deficiencies, this application provides a mixing device for the production of fungicides, aiming to improve the problems mentioned in the above background art.

[0007] An embodiment of this application provides a mixing device for the production of fungicides, including a tank body. A rotating shaft is arranged inside the tank body. A centrifugal fan is arranged at the lower end of the rotating shaft. An outlet is opened at the lower end of the tank body. The centrifugal fan movably seals the outlet. A lifting member is arranged on the tank body. The lifting member drives the rotating shaft to move axially. A driving member is shaft-connected to the rotating shaft. A stirring member is decelerated and connected to the rotating shaft.

[0008] In a specific implementation, the driving member includes a machine base and a motor. The motor is installed on the top of the tank body through the machine base.

[0009] In a specific implementation, the driving member further includes a plum blossom-type coupling. The output end of the motor is shaft-connected to the rotating shaft through the coupling.

[0010] In the above implementation process, the motor is shaft-connected to the rotating shaft through the coupling. At the same time, the rotating shaft can axially move a certain distance under the drive of the lifting member, thereby driving the centrifugal fan to open and seal the outlet.

[0011] In a specific embodiment, the lifting member includes a rotating frame and an electric cylinder. The rotating frame is rotatably connected to the rotating shaft. The electric cylinder is installed at the top end of the tank body, and the telescopic end of the electric cylinder is fixedly connected to the rotating frame.

[0012] In the above implementation process, the electric cylinder drives the axial movement of the rotating shaft through the rotating frame without affecting the rotation of the rotating shaft.

[0013] In a specific embodiment, the stirring member includes a sleeve. The sleeve is rotatably connected to the rotating shaft, and stirring blades are arranged outside the sleeve.

[0014] In the above implementation process, the stirring blades are in the same driving direction as the centrifugal fan under the drive of the rotating shaft, jointly promoting the circulation and mixing of the internal fungicide.

[0015] In a specific embodiment, the stirring member further includes a planetary reduction mechanism. The planetary reduction mechanism includes a ring gear, a sun gear, three planetary gears and a carrier of the planetary gears. The ring gear is fixedly connected to the sleeve, the sun gear is fixedly connected to the rotating shaft, and the carrier is rotatably connected to the rotating shaft.

[0016] In a specific embodiment, the stirring member further includes a sliding sleeve. The sliding sleeve is fixedly connected to the inner wall of the tank body, and a sliding rod is fixedly connected to the carrier and inserted into the sliding sleeve.

[0017] In the above implementation process, when the rotating shaft rotates, it drives the sun gear to rotate. Since the sliding rod on the carrier is restricted in the sliding sleeve, the carrier cannot rotate, that is, the planetary gears can rotate but not revolve. Thus, the ring gear rotates in the opposite direction relative to the sun gear, that is, the sleeve rotates in the opposite direction relative to the rotating shaft, and the sleeve is decelerated, so that the rotation speed of the stirring blades matches the rotation speed of the centrifugal fan. On the other hand, since the sleeve will move up and down, the movement of the sliding rod in the sliding sleeve is used to keep the carrier circumferentially fixed.

[0018] In a specific embodiment, gaskets are arranged at the positions where the discharge port contacts the centrifugal fan.

[0019] In the above implementation process, gaskets are attached to both the upper and lower sides of the contact surface. In this embodiment, the gaskets are made of polytetrafluoroethylene, which has certain elasticity and very small frictional resistance, and is used to achieve the sealing between the centrifugal fan and the discharge port and reduce the frictional resistance between the centrifugal fan and the discharge port.

[0020] Compared with the prior art, the beneficial effects of the present application are as follows: Using the centrifugal fan as a valve to block the discharge port at the lower end of the tank body, the opening degree of the discharge port can be controlled to control the discharge speed, and the solution at the bottom of the tank body can also be sprayed out around, thus avoiding the deposition of raw materials. The rotation of the centrifugal fan can also shake off the attached solution, thereby improving the ease of cleaning. Description of the Drawings

Specific embodiments

[0027] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application.

[0028] Please refer to Figures 1 - 4 , the present application provides a mixing device for the production of fungicides, including a tank body 10. A rotating shaft 20 is arranged inside the tank body 10. A centrifugal fan 30 is arranged at the lower end of the rotating shaft 20. A discharge port 40 is opened at the lower end of the tank body 10. The centrifugal fan 30 movably seals the discharge port 40. A lifting member 50 is arranged on the tank body 10. The lifting member 50 drives the axial movement of the rotating shaft 20. A driving member 60 is shaft-connected to the rotating shaft 20. A stirring member 70 is connected to the rotating shaft 20 in a decelerating manner. Among them, using the centrifugal fan 30 as a valve to block the discharge port 40 at the lower end of the tank body 10 can control the opening degree of the discharge port 40 to control the discharge speed, and can also spray the solution at the bottom of the tank body 10 around, thereby avoiding the deposition of raw materials. The rotation of the centrifugal fan 30 can also shake off the attached solution, thereby improving the ease of cleaning.

[0029] Please refer to Figures 1 - 4, the driving member 60 includes a machine base 61 and a motor 62. The motor 62 is installed at the top end of the tank body 10 through the machine base 61. The driving member 60 further includes a plum blossom type coupling 63. The output end of the motor 62 is axially connected to the rotating shaft 20 through the coupling 63. The motor 62 is axially connected to the rotating shaft 20 through the coupling 63. At the same time, the rotating shaft 20 can axially move a certain distance under the drive of the lifting member 50, so as to drive the centrifugal fan 30 to open and block the discharge port 40.

[0030] Please refer to Figures 1 - 4 , the lifting member 50 includes a rotating frame 51 and an electric cylinder 52. The rotating frame 51 is rotatably connected to the rotating shaft 20. The electric cylinder 52 is installed at the top end of the tank body 10. The telescopic end of the electric cylinder 52 is fixedly connected to the rotating frame 51. The electric cylinder 52 drives the rotating shaft 20 to axially move through the rotating frame 51, and does not affect the rotation of the rotating shaft 20 itself.

[0031] Please refer to Figures 1 - 4 , the stirring member 70 includes a sleeve 71. The sleeve 71 is rotatably connected to the rotating shaft 20. Stirring blades 72 are arranged outside the sleeve 71. The stirring blades 72 are driven by the rotating shaft 20 in the same direction as the pushing direction of the centrifugal fan 30, and jointly promote the circulation and mixing of the internal fungicide.

[0032] Please refer to Figures 1 - 4 , the stirring member 70 further includes a planetary reduction mechanism 73. The planetary reduction mechanism 73 includes a ring gear, a sun gear, three planetary gears and a carrier of the planetary gears. The ring gear is fixedly connected to the sleeve 71. The sun gear is fixedly connected to the rotating shaft 20. The carrier is rotatably connected to the rotating shaft 20. The stirring member 70 further includes a sliding sleeve 74. The sliding sleeve 74 is fixedly connected to the inner wall of the tank body 10. A sliding rod 75 is fixedly connected to the carrier and inserted into the sliding sleeve 74. When the rotating shaft 20 rotates, it drives the sun gear to rotate. Since the sliding rod 75 on the carrier is restricted in the sliding sleeve 74, the carrier cannot rotate, that is, the planetary gears can rotate but cannot revolve. Therefore, the ring gear rotates in the opposite direction relative to the sun gear, that is, the sleeve 71 rotates in the opposite direction relative to the rotating shaft 20, and the sleeve 71 is decelerated, so that the rotation speed of the stirring blades 72 matches the rotation speed of the centrifugal fan 30. On the other hand, since the sleeve 71 will move up and down, the movement of the sliding rod 75 in the sliding sleeve 74 is used to keep the carrier circumferentially fixed.

[0033] Please refer to Figures 1 - 4 , gaskets 80 are arranged at the positions where the discharge port 40 contacts the centrifugal fan 30. Gaskets 80 are attached to both the upper and lower sides of the contact surface. In this embodiment, the gaskets 80 are made of polytetrafluoroethylene, which has a certain elasticity and a very small frictional resistance, and is used to achieve the sealing between the centrifugal fan 30 and the discharge port 40, and reduce the frictional resistance between the centrifugal fan 30 and the discharge port 40.

[0034] The working principle of the mixing device for producing the fungicide is as follows: The motor 62 drives the rotation of the rotating shaft 20 through the coupling 63, and then drives the high-speed rotation of the centrifugal fan 30, spraying the fungicide solution at the bottom in all directions to avoid the deposition of raw materials. At the same time, the rotating shaft 20 drives the rotation of the stirring member 70 through the planetary reduction mechanism 73, and cooperates with the centrifugal fan 30 to further promote the circulation of the fungicide solution in the tank body 10, which is beneficial to improving the mixing effect. After the stirring is completed, the electric cylinder 52 drives the rotating shaft 20 to move upward through the rotating frame 51, thereby pulling the centrifugal fan 30 away from the discharge port 40, and the mixed fungicide solution is discharged from the discharge port 40. The discharge speed can be controlled by the distance between the centrifugal fan 30 and the discharge port 40. When the discharging is completed, the motor 62 drives the centrifugal fan 30 and the stirring rod to rotate at high speed, throwing out the remaining solution, which is discharged from the discharge port 40 along the lower end of the tank body 10. In summary, by using the centrifugal fan 30 as a valve to block the discharge port 40 at the lower end of the tank body 10, the opening degree of the discharge port 40 can be controlled to control the discharge speed, and the solution at the bottom of the tank body 10 can also be sprayed in all directions to avoid the deposition of raw materials. The rotation of the centrifugal fan 30 can also throw off the attached solution, thereby improving the ease of cleaning.

[0035] The above are only the embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, improvement or equivalent replacement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
