Abstract
Description
Technical Field
[0001] This application relates to the field of mixing equipment technology, specifically a spiral powder slurry mixing device. Background Technology
[0002] Powder slurry preparation is a common process in chemical production, which involves mixing solid powders with liquids such as water and stirring them in a container to form a slurry.
[0003] An existing patent (publication number: CN210729194U) discloses a powder pulping device, which includes: a cylinder, a wetting mechanism and a stirring mechanism disposed within the cylinder; wherein, a feeding port is opened at the top of the cylinder, and a pulp outlet is opened at the bottom of the cylinder; the wetting mechanism is disposed at the top of the cylinder for wetting the powder conveyed by the feeding port; the stirring mechanism is disposed below the wetting mechanism for stirring the wetting powder to form a pulp. In this utility model, the powder input into the cylinder is pre-wetted by the wetting mechanism, so that the powder is fully wetted, avoiding the powder floating on the water surface as in the prior art; then the stirring mechanism stirs the wetted powder, which facilitates the formation of pulp and effectively improves the pulping speed. Furthermore, the continuous movement of the powder within the cylinder can significantly increase the pulping speed and facilitate continuous operation.
[0004] While the device described in the aforementioned comparative document can significantly increase the pulping speed, the pulp at the bottom will remain deposited for a long time during the mixing process, making it impossible to agitate the pulp at the bottom and potentially leading to mixing dead zones. To address this issue, a spiral powder pulping and mixing device is proposed. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a spiral powder slurry mixing device, which improves the efficiency of mixing and conveying, and can effectively avoid material accumulation and reduce dead zones.
[0006] To achieve the above objectives, this application provides the following technical solution: a spiral powder slurry mixing device, comprising a mixing tank, a top cover, and a mixing mechanism. The mixing mechanism includes a servo motor fixedly connected to the upper surface of the top cover and a first bevel gear fixedly connected to the output shaft end of the servo motor, as well as a sleeve rotatably sleeved on the inner wall of the top cover. A second bevel gear is fixedly connected to the top end of the sleeve, a sealed bearing is fixedly connected to the inner wall of the second bevel gear, a sleeve rod is fixedly connected to the inner wall of the sealed bearing, and a third bevel gear meshing with the first bevel gear is fixedly connected to the top end of the sleeve rod.
[0007] The bottom end of the sleeve is fixedly connected to a sleeve, the bottom end of the sleeve rod is fixedly connected to a spiral blade, the top of the sleeve is provided with a discharge port, the inner wall of the sleeve is provided with multiple through holes, the inner wall of the sleeve is fixedly connected with multiple protruding particles, and the outer surface of the sleeve is fixedly connected with multiple stirring rods.
[0008] Through the above scheme, the mixing mechanism can continuously convey the slurry at the bottom of the mixing tank upwards, avoiding local sedimentation of the slurry, reducing the occurrence of mixing dead zones, and optimizing the efficiency and quality of powder slurry preparation. When the servo motor starts, the sleeve and the spiral blade can be rotated in opposite directions by the first, second, and third bevel gears. When the spiral blade rotates, it can push the slurry at the bottom of the mixing tank upwards inside the sleeve. The sleeve, which is in the opposite direction to the spiral blade, can form an alternating flow direction, avoiding the accumulation of powder due to single rotation, making the feeding operation of the spiral blade smoother. At the same time, the rotating stirring rod can make the slurry outside the sleeve evenly mixed.
[0009] Furthermore, the top cover is bolted to the top of the mixing tank.
[0010] The above solution allows for easy disassembly and assembly of the top cover on the mixing tank, facilitating regular cleaning of the inner wall of the mixing tank and the mixing mechanism, and promoting the reuse of the device.
[0011] Furthermore, two wall-mounting plates are fixedly connected to the outer surface of the sleeve, and both wall-mounting plates are adapted to the inner wall of the mixing tank.
[0012] With the above scheme, when the sleeve rotates, it can drive the two hanging plates to rotate. The rotation of the two hanging plates can scrape off the slurry adhering to the inner wall of the mixing tank, thereby improving the uniformity of slurry mixing.
[0013] Furthermore, an L-shaped bracket is fixedly connected to the upper surface of the top cover, and the top end of the sleeve rod is rotatably connected to the inner wall of the L-shaped bracket.
[0014] The L-shaped bracket provided by the above scheme can improve the stability of the sleeve rod, making the transmission between the first bevel gear, the second bevel gear and the third bevel gear more stable.
[0015] Furthermore, a measuring bar is installed on the outer surface of the mixing tank, and four support columns are fixedly connected to the outer surface of the mixing tank.
[0016] The above scheme allows the measuring bar to be used to observe the content of the slurry inside the mixing tank, and the support column can make the device more stable on the contact surface.
[0017] Furthermore, a feeding port is installed on the upper surface of the top cover, and the output end of the feeding port is connected to the interior of the mixing tank.
[0018] The above-described design allows for the addition of powder and liquid materials into the mixing tank through the feeding port, making it convenient to use.
[0019] Furthermore, a discharge port is installed at the bottom of the mixing tank, and a solenoid valve is installed inside the discharge port.
[0020] With the above method, when the solenoid valve is opened, the slurry that has been mixed inside the mixing tank can be discharged through the outlet.
[0021] Furthermore, a controller is fixedly connected to the outer surface of the mixing tank, and the servo motor and solenoid valve are both electrically connected to the controller.
[0022] The above-described controller can control the opening and closing of the servo motor and solenoid valve, simplifying the operation process.
[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0024] This spiral powder pulping and mixing device cleverly solves the problems of localized sedimentation and mixing dead zones found in traditional powder pulping and mixing equipment. Through its mixing mechanism, the device continuously conveys the slurry from the bottom of the mixing tank upwards, ensuring thorough mixing and improving pulping efficiency and quality. Its core principle lies in using a servo motor to drive the first, second, and third bevel gears to rotate, thereby driving the sleeve and spiral blades to rotate in opposite directions. The rotation of the spiral blades acts on the inside of the sleeve, pushing the slurry upwards from the bottom, while the reverse rotation of the sleeve creates alternating flow directions, ensuring that the slurry does not accumulate due to a single rotation. Furthermore, the rotating stirring rod effectively stirs the slurry outside the sleeve, achieving uniform mixing. In summary, this spiral powder pulping and mixing device, through structural innovation and rational layout, effectively improves pulping efficiency and quality while avoiding the drawbacks of traditional equipment.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0034] Please see Figure 1 , Figure 2 and Figure 6This embodiment of a spiral powder slurry mixing device includes a mixing tank 1, a top cover 2, and a mixing mechanism 3. The mixing mechanism 3 includes a servo motor 301 fixedly connected to the upper surface of the top cover 2 and a first bevel gear 302 fixedly connected to the output shaft end of the servo motor 301, as well as a sleeve 303 rotatably sleeved on the inner wall of the top cover 2. A second bevel gear 304 is fixedly connected to the top end of the sleeve 303. A sealed bearing 305 is fixedly connected to the inner wall of the second bevel gear 304. A sleeve rod 306 is fixedly connected to the inner wall of the sealed bearing 305. A third bevel gear 307 that meshes with the first bevel gear 302 is fixedly connected to the top end of the sleeve rod 306. When the servo motor 301 is started, it can drive the first bevel gear 302 to rotate. The rotation of the first bevel gear 302 can cause the second bevel gear 304 and the third bevel gear 307 to rotate. When the second bevel gear 304 and the third bevel gear 307 rotate, the sleeve 303 and the sleeve rod 306 can rotate in opposite directions. At the same time, the sealed bearing 305 can make the sleeve 303 and the sleeve rod 306 rotate more smoothly and without motion interference. An L-shaped bracket 315 is fixedly connected to the upper surface of the top cover 2. The top of the sleeve rod 306 is rotatably connected to the inner wall of the L-shaped bracket 315. The L-shaped bracket 315 can improve the stability of the sleeve rod 306 and make the transmission between the first bevel gear 302, the second bevel gear 304 and the third bevel gear 307 more stable.
[0035] Please see Figure 3 , Figure 4 and Figure 5A sleeve 308 is fixedly connected to the bottom end of the sleeve 303, and a spiral blade 314 is fixedly connected to the bottom end of the sleeve rod 306. When the sleeve 303 and sleeve rod 306 rotate, the sleeve 308 and spiral blade 314 rotate in opposite directions. The rotation of the spiral blade 314 pushes the slurry at the bottom of the mixing tank 1 upward through the inside of the sleeve 308, while the reverse rotation of the sleeve 308 allows the slurry to be conveyed upward more smoothly. A discharge port 309 is provided at the top of the spiral blade 314 and sleeve 308, through which the slurry conveyed inside the sleeve 308 can be discharged. Multiple through holes 310 are provided on the inner wall of the sleeve 308, and multiple protruding particles 31 are fixedly connected to the inner wall of the sleeve 308. 1. The through-hole 310 and the fixedly connected protruding particles 311 allow the slurry to be repeatedly sheared and disturbed inside the sleeve 308, thereby significantly improving the mixing uniformity. Multiple stirring rods 312 are fixedly connected to the outer surface of the sleeve 308, and two hanging plates 313 are fixedly connected to the outer surface of the sleeve 308. Both hanging plates 313 are adapted to the inner wall of the mixing tank 1. When the sleeve 308 rotates, it can drive the multiple stirring rods 312 and the two hanging plates 313 to rotate. The rotation of the multiple stirring rods 312 can uniformly stir and mix the slurry outside the sleeve 308, and the rotation of the two hanging plates 313 can scrape off the slurry adhering to the inner wall of the mixing tank 1, thereby improving the mixing uniformity of the slurry.
[0036] Please see Figure 1 and Figure 2 The top cover 2 is bolted to the top of the mixing tank 1. By defining the connection between the top cover 2 and the mixing tank 1, the top cover 2 can be easily disassembled and reassembled on the mixing tank 1, which facilitates the regular cleaning of the inner wall of the mixing tank 1 and the mixing mechanism 3, and is beneficial to the reuse of the device. A measuring bar 4 is installed on the outer surface of the mixing tank 1, and four support columns 5 are fixedly connected to the outer surface of the mixing tank 1. The measuring bar 4 can be used to observe the content of the slurry inside the mixing tank 1, and the support columns 5 can make the device more stably placed on the contact surface.
[0037] Please see Figure 1 , Figure 2 and Figure 3The top surface of the top cover 2 is equipped with a feeding port 6. The output end of the feeding port 6 is connected to the inside of the mixing tank 1. Powder and liquid materials can be added into the mixing tank 1 through the feeding port 6 for easy use. The bottom of the mixing tank 1 is equipped with a discharge port 7. A solenoid valve 8 is installed inside the discharge port 7. When the solenoid valve 8 is opened, the slurry that has been mixed inside the mixing tank 1 can be discharged through the discharge port 7. A controller 9 is fixedly connected to the outer surface of the mixing tank 1. The servo motor 301 and the solenoid valve 8 are both electrically connected to the controller 9. The controller 9 can control the opening or closing of the servo motor 301 and the solenoid valve 8, simplifying the operation process.
[0038] In this embodiment, a spiral powder slurry mixing device is provided. The mixing mechanism 3 can continuously convey the slurry at the bottom of the mixing tank 1 upwards, avoiding local sedimentation of the slurry, reducing the occurrence of mixing dead zones, and optimizing the efficiency and quality of powder slurry preparation. When the servo motor 301 is started, the sleeve 308 and the spiral blade 314 can be rotated in opposite directions by the first bevel gear 302, the second bevel gear 304, and the third bevel gear 307. When the spiral blade 314 rotates, it can push the slurry at the bottom of the mixing tank 1 upwards inside the sleeve 308. The sleeve 308, which is in the opposite direction to the spiral blade 314, can form an alternating flow direction, avoiding the accumulation of powder due to single rotation, making the feeding operation of the spiral blade 314 smoother. At the same time, the rotating stirring rod 312 and the hanging plate 313 can make the slurry outside the sleeve 308 evenly mixed.
[0039] The working principle of the above embodiment is as follows: Appropriate amounts of powder and liquid are fed into the inner wall of the mixing tank 1 through the feeding port 6. Then, the servo motor 301 is started by the controller 9. When the servo motor 301 starts, it drives the first bevel gear 302 to rotate. When the first bevel gear 302 rotates, the sleeve 303 and the sleeve rod 306 rotate in opposite directions through the second bevel gear 304 and the third bevel gear 307. The sealed bearing 305 ensures that the rotation of the sleeve 303 and the sleeve rod 306 does not interfere with each other and the rotation is smoother. When the sleeve rod 306 rotates, it drives the spiral blade 314 to rotate, and when the sleeve 303 rotates, it drives the sleeve 308 to rotate. The sleeve 308 rotates in the opposite direction to the spiral blade 314. When the spiral blade 314 rotates, it pushes the slurry at the bottom of the mixing tank 1 upward through the sleeve 308. The through holes 310 on the surface of the sleeve 308 and the protruding particles 311 fixedly connected to the inner wall of the sleeve 308 continuously change relative to each other. At the positions of the powder and liquid, a complex flow field is formed. The powder and liquid are repeatedly sheared and disturbed inside the sleeve 308, as well as at the through hole 310 and the protruding particles 311, thereby significantly improving the mixing uniformity. Furthermore, the counter-rotation of the sleeve 308 and the spiral blade 314 creates an alternating flow direction, avoiding the accumulation of powder caused by a single rotation. This allows the slurry at the bottom of the mixing tank 1 to be pushed upward through the sleeve 308 and finally discharged through the discharge port 309 to the upper position inside the mixing tank 1. This achieves the effect of continuously turning over the slurry inside the mixing tank 1, preventing local sedimentation. At the same time, when the sleeve 308 rotates, it also causes the stirring rod 312 and the hanging plate 313 to rotate. The rotation of the stirring rod 312 can uniformly stir the slurry outside the sleeve 308, and the rotation of the hanging plate 313 can scrape off the slurry adhering to the inner wall of the mixing tank 1, reducing the probability of mixing dead corners inside the mixing tank 1, thereby effectively improving the efficiency and quality of powder slurry preparation.
