Description

Technical Field

[0001] This invention relates to the field of mixing technology, specifically to a mixing device with a multi-stage mixing function that has quantitative input. Background Technology

[0002] In industrial production, powder mixing is usually done using powder mixers, which are widely used. Existing mixers typically use a motor to drive the mixing blades. However, during the mixing process, the bottom is mixed first, and the material falling from the top is mixed later. This localized mixing is uneven, the mixing effect is poor, and the coaxiality of the long mixing shaft is difficult to control. Poor coaxiality can lead to eccentricity and uneven force distribution. The motor output torque loss is large, the power utilization rate is low, and the eccentricity of the mixing shaft makes the blades easy to scratch the inner wall of the cylinder. It is also prone to failure, affecting the mixing efficiency and normal use of the equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a mixing device with a multi-stage mixing function for quantitative input, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A mixing device with a quantitative input multi-stage mixing function includes: a body, the body being composed of a mixing chamber and two feed pipes, the two feed pipes being symmetrically arranged on both sides of the mixing chamber and communicating with the mixing chamber; two mixing pipes being symmetrically arranged at the top of the mixing chamber; a discharge port being provided at the bottom of the mixing chamber; and a mixing device being provided inside the mixing chamber, the mixing device including: a power chamber being located at the top of the mixing chamber;

[0006] Workers connect the main powder and additives to the feed pipe and mixing pipe according to the proportions. The main powder is then transported to the mixing chamber through the feed pipe. Once the main powder enters the mixing chamber, the controller starts the mixing device, which then agitates the powder in the mixing chamber. During agitation, the mixing device adds the additives from the mixing pipe to the mixing chamber in measured amounts, thus achieving quantitative addition in small amounts multiple times. This avoids insufficient mixing of the powder, which could lead to clumping. This improves the thoroughness and quality of powder mixing, and the agitation of the mixing device also increases the efficiency of powder mixing.

[0007] Preferably, a rotating ring is rotatably connected to the outer wall of the mixing pipe. The rotating ring is provided with a plurality of rotating teeth, which are arranged around the axis of the rotating ring. A transmission gear is provided between two of the rotating teeth. A motor is provided on the transmission gear. The drive shaft of the motor is connected to the transmission gear. The transmission gear meshes with the two rotating rings for transmission.

[0008] Preferably, each of the mixing tubes is provided with an arc-shaped block, and a metering ring is provided on the side of the arc-shaped block near the rotating teeth. The metering ring passes through the mixing tube and connects to the rotating ring. The metering ring is rotatably connected to the mixing tube. A notch is provided on the metering ring, and the notch corresponds to the arc-shaped block.

[0009] Preferably, a gear ring is provided on the side of the mixing chamber near the mixing pipe. The gear ring is crescent-shaped. A moving groove is provided on the side of the gear ring near the inner wall of the mixing chamber. The moving groove is figure-eight shaped. The crescent-shaped notches of the two gear rings are arranged opposite each other. A crescent-shaped block is provided on the side of the rotating ring located in the mixing chamber. The two crescent-shaped blocks rotate in opposite directions.

[0010] Preferably, the crescent block has a stirring chamber inside, and two arc-shaped grooves are provided inside the crescent block. The two arc-shaped grooves are symmetrically arranged along the axis of the stirring chamber. One end of the arc-shaped groove is connected to the mixing chamber, and the other end of the arc-shaped groove is connected to the stirring chamber.

[0011] Preferably, a rotating shaft is slidably connected inside the moving groove, and a rotating gear is provided on the side of the rotating shaft near the moving groove. The rotating gear meshes with a gear ring, and a rotating shaft is provided on the side of the rotating shaft away from the rotating gear. The rotating shaft extends into the stirring chamber.

[0012] Preferably, the rotating shaft is provided with a spiral plate inside the stirring chamber, and the spiral plate is provided with a plurality of baffles arranged spirally around the axis of the spiral plate. A hollow tube is provided at the axis of the spiral plate, and one side of the baffle is connected to the hollow tube. The spiral plate is rotatably connected to the stirring chamber.

[0013] Preferably, the mixing pipe has a feed inlet on the side near the crescent block, the two feed inlets are arranged opposite each other, and the crescent block is rotatably connected to the mixing pipe;

[0014] After the main powder enters the mixing chamber through the feed pipe, the additive enters the mixing pipe. Then, the controller starts the motor in the power chamber. The drive shaft in the motor drives the transmission gear to rotate. During the rotation of the transmission gear, the transmission gear meshes with the transmission rotating gear, and the rotating gear rotates. When the rotating gear rotates, it drives the rotating ring to rotate, causing the two rotating rings to rotate to opposite sides. During the rotation of the rotating ring, the rotating ring drives the metering ring to rotate. When the notch of the metering ring coincides with the arc block, the feed port and the mixing chamber are closed. When the notch of the metering ring does not coincide with the arc block, the feed port and the mixing chamber are connected, allowing the additive to enter the mixing chamber through the mixing pipe.

[0015] During the rotation of the rotating ring, the rotating ring drives the crescent block to rotate. The crescent block rotates around the axis of the rotating ring. During the rotation of the crescent block, it pushes the powder in the mixing chamber. Some of the powder enters the mixing chamber through the arc groove. At the same time, the crescent block drives the mixing chamber to rotate. The mixing chamber revolves around the axis of the rotating ring. When the crescent block rotates, it also drives the self-rotating shaft to rotate. The self-rotating shaft then rotates along the moving groove. Since there is a rotating gear at the top of the self-rotating shaft, during the rotation of the self-rotating shaft around the axis of the rotating ring, the rotating gear meshes with the gear ring. The rotating gear rotates along the axis of the rotating ring. During the rotation of the rotating gear, the side with the longer arc edge of the rotating gear and the gear ring moves to the side with the shorter arc edge of the other gear ring.

[0016] The rotating gear then rotates under the action of the gear ring, causing the rotating gear to rotate on its own axis. During the rotation of the rotating gear, it drives the rotating shaft to rotate, which in turn drives the rotating shaft to rotate. During the rotation of the rotating shaft, the rotating shaft drives the spiral plate to rotate within the mixing chamber. The rotation of the spiral plate drives the baffle to rotate. The spiral plate and the baffle work together to mix the powder in the mixing chamber. During the mixing process, some of the powder moves into the hollow tube under the action of the baffle. Under the action of centrifugal force, the powder is thrown to the next layer of baffle, so that the powder is fully mixed in the mixing chamber. After a period of mixing, the controller controls the outlet to open, and the mixture is then conveyed through the mixing chamber to the outlet and discharged from the outlet. During the discharge process, the two crescent-shaped blocks are still rotating, which pushes the mixture to move, thereby accelerating the efficiency of the mixture being discharged from the outlet.

[0017] Because the moving trough is figure-eight shaped, a portion of the rotation stroke of the two crescent-shaped blocks overlaps during their rotation. This allows the powder within the rotation stroke to be stirred and mixed by the two crescent-shaped blocks, thereby improving the efficiency of powder mixing. Furthermore, with the combination of revolution and rotation, the spiral plate works in conjunction with the mixing chamber to thoroughly disperse the powder, ensuring that the main powder and additives are fully mixed. This improves the thoroughness and quality of powder mixing, and the combined effect of rotation and revolution also enhances the mixing efficiency of the powder within the mixing chamber.

[0018] While the rotating ring drives the crescent block to rotate, it also drives the metering ring to rotate, which in turn causes the metering ring to coincide with the arc block at a certain time. This achieves the timed closure of the mixing pipe, thus ensuring a constant amount of material is delivered from the mixing pipe to the mixing chamber. This allows for small, frequent additions, saves additional driving force, improves the quality of powder mixing, reduces energy consumption, and increases energy utilization.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. Because the moving trough is figure-eight shaped, a portion of the rotation stroke of the two crescent-shaped blocks overlaps during their rotation. This allows the powder within the rotation stroke to be stirred and mixed by the two crescent-shaped blocks, thereby improving the efficiency of powder mixing. Furthermore, with the combination of revolution and rotation, the spiral plate works in conjunction with the mixing chamber to thoroughly disperse the powder, ensuring that the main powder and additives are fully mixed. This improves the thoroughness and quality of powder mixing, and the combined effect of rotation and revolution also enhances the mixing efficiency of the powder within the mixing chamber.

[0021] 2. The rotating ring drives the crescent block to rotate, which in turn drives the metering ring to rotate. This causes the metering ring to coincide with the arc block at a specific time, thus achieving a timed closure of the mixing pipe. This ensures that the amount of material added from the mixing pipe to the mixing chamber remains constant, allowing for multiple small additions. This also saves on additional driving force, thereby improving the quality of powder mixing, reducing energy consumption, and increasing energy utilization. Attached Figure Description

[0035] 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.

[0036] Please see Figures 1-10 The present invention provides the following technical solution:

[0037] A mixing device with a quantitative input multi-stage mixing function includes: a body 1, which is composed of a mixing chamber 11 and two feed pipes 12, the two feed pipes 12 being symmetrically arranged on both sides of the mixing chamber 11 and communicating with the mixing chamber 11; two mixing pipes 13 being symmetrically arranged at the top of the mixing chamber 11; a discharge port 14 being provided at the bottom of the mixing chamber 11; and a mixing device 2 being provided inside the mixing chamber 11, the mixing device 2 including: a power chamber 21, which is located at the top of the mixing chamber 11;

[0038] According to the mixing ratio, the staff connects the main powder and the additives to the feed pipe 12 and the mixing pipe 13 respectively. Then, the main powder is transported to the mixing chamber 11 through the feed pipe 12. After the main powder enters the mixing chamber 11, the controller controls the mixing device 2 to start. The mixing device 2 then stirs the powder in the mixing chamber 11. During the stirring process, the mixing device 2 drives the additives in the mixing pipe 13 to be added quantitatively to the mixing chamber 11, thereby realizing quantitative addition in small amounts and multiple times. This avoids insufficient mixing of the powder, which would lead to powder clumping. This improves the fullness of powder mixing, improves the quality of powder mixing, and also improves the efficiency of powder mixing through the stirring of the mixing device 2.

[0039] In one specific embodiment of the present invention, a rotating ring 22 is rotatably connected to the outer wall of the mixing pipe 13. The rotating ring 22 is provided with a plurality of rotating teeth 221, which are arranged around the axis of the rotating ring 22. A transmission gear is provided between two rotating teeth 221, and a motor is provided on the transmission gear. The drive shaft of the motor is connected to the transmission gear, and the transmission gear meshes with the two rotating rings 22 for transmission.

[0040] In one specific embodiment of the present invention, each mixing tube 13 is provided with an arc-shaped block 131, and a metering ring 222 is provided on the side of the arc-shaped block 131 near the rotating tooth 221. The metering ring 222 passes through the mixing tube 13 and is connected to the rotating ring 22. The metering ring 222 is rotatably connected to the mixing tube 13. A notch is provided on the metering ring 222, and the notch corresponds to the arc-shaped block 131.

[0041] In one specific embodiment of the present invention, a gear ring 23 is provided on the side of the mixing chamber 11 near the mixing pipe 13. The gear ring 23 is crescent-shaped. A moving groove 231 is provided on the side of the gear ring 23 near the inner wall of the mixing chamber 11. The moving groove 231 is figure-eight shaped. The crescent-shaped notches of the two gear rings 23 are arranged opposite to each other. A crescent block 24 is provided on one side of the rotating ring 22 located in the mixing chamber 11. The two crescent blocks 24 rotate in opposite directions.

[0042] In one specific embodiment of the present invention, a stirring chamber 25 is provided inside the crescent block 24, and two arc-shaped grooves 26 are provided inside the crescent block 24. The two arc-shaped grooves 26 are symmetrically arranged along the axis of the stirring chamber 25. One end of the arc-shaped groove 26 is connected to the mixing chamber 11, and the other end of the arc-shaped groove 26 is connected to the stirring chamber 25.

[0043] In one specific embodiment of the present invention, a rotating shaft 27 is slidably connected in the moving groove 231. A rotating gear 271 is provided on the side of the rotating shaft 27 near the moving groove 231. The rotating gear 271 meshes with the gear ring 23. A rotating shaft 272 is provided on the side of the rotating shaft 27 away from the rotating gear 271. The rotating shaft 272 extends into the stirring chamber 25.

[0044] In one specific embodiment of the present invention, the rotating shaft 272 is provided with a spiral plate 28 inside the stirring chamber 25. A plurality of baffles 281 are provided on the spiral plate 28, and the plurality of baffles 281 are spirally arranged around the axis of the spiral plate 28. A hollow tube 282 is provided at the axis of the spiral plate 28, and one side of the baffle 281 is connected to the hollow tube 282. The spiral plate 28 is rotatably connected to the stirring chamber 25.

[0045] In one specific embodiment of the present invention, the mixing pipe 13 is provided with a feed inlet 132 on the side near the crescent block 24, the two feed inlets 132 are arranged opposite to each other, and the crescent block 24 is rotatably connected to the mixing pipe 13.

[0046] After the main powder enters the mixing chamber 11 through the feed pipe 12, the additive enters the mixing pipe 13. Then, the controller starts the motor in the power chamber 21. The drive shaft in the motor drives the transmission gear to rotate. During the rotation of the transmission gear, the transmission gear meshes with the transmission rotating gear 221, and the rotating gear 221 rotates. When the rotating gear 221 rotates, it drives the rotating ring 22 to rotate, so that the two rotating rings 22 rotate to opposite sides. During the rotation of the rotating ring 22, the rotating ring 22 drives the metering ring 222 to rotate. When the notch of the metering ring 222 coincides with the arc block 131, the feed port 132 is closed to the mixing chamber 11. When the notch of the metering ring 222 does not coincide with the arc block 131, the feed port 132 is connected to the mixing chamber 11, so that the additive can enter the mixing chamber 11 through the mixing pipe 13.

[0047] During the rotation of the rotating ring 22, the rotating ring 22 drives the crescent block 24 to rotate. The crescent block 24 rotates around the axis of the rotating ring 22. During the rotation of the crescent block 24, it pushes the powder in the mixing chamber 11. A part of the powder enters the stirring chamber 25 through the arc groove 26. While the crescent block 24 is rotating, it drives the stirring chamber 25 to rotate. The stirring chamber 25 revolves around the axis of the rotating ring 22. When the crescent block 24 rotates, it also drives the rotating shaft 27 to rotate. The rotating shaft 27 then rotates along the moving groove 231. Since the rotating shaft 27 is provided with a rotating gear 271 at the top, during the rotation of the rotating shaft 27 around the axis of the rotating ring 22, the rotating gear 271 meshes with the gear ring 23. The rotating gear 271 rotates along the axis of the rotating ring 22. During the rotation of the rotating gear 271, the side with the longer arc of the rotating gear 271 and the gear ring 23 moves to the side with the shorter arc of the other gear ring 23.

[0048] The rotating gear 271 then rotates under the action of the gear ring 23, causing the rotating gear 271 to rotate on its own axis. During the rotation of the rotating gear 271, it drives the rotation shaft 27 to rotate, which in turn drives the rotating shaft 272 to rotate. During the rotation of the rotating shaft 272, the rotating shaft 272 drives the spiral plate 28 to rotate within the mixing chamber 25. When the spiral plate 28 rotates, it drives the baffle 281 to rotate. The spiral plate 28 and the baffle 281 cooperate with each other to stir and mix the powder in the mixing chamber 25. During the stirring and mixing process, a portion of the powder... The material moves into the hollow tube 282 under the action of the baffle 281. Under the action of centrifugal force, the powder is thrown to the next baffle 281, so that the powder is fully stirred in the mixing chamber 25. After a period of stirring and mixing, the controller controls the outlet 14 to open. The mixture is then conveyed to the outlet 14 through the mixing chamber 11 and discharged from the outlet 14. During the discharge process, the two crescent blocks 24 are still rotating, which pushes the mixture to move, thereby speeding up the efficiency of the mixture being discharged from the outlet 14.

[0049] Because the moving groove 231 is in the shape of an "8", the two crescent blocks 24 overlap in part of their rotation stroke during rotation. This allows the powder in the rotation stroke to be stirred and mixed by the two crescent blocks 24, thereby improving the efficiency of powder mixing. Furthermore, with the combination of revolution and rotation, the spiral plate 28 and the mixing chamber 25 work together to fully disperse the powder, thereby ensuring that the main powder and the additives are fully mixed, thus improving the fullness of powder mixing. In addition, the combination of rotation and revolution also improves the mixing efficiency of the powder in the mixing chamber 11.

[0050] While the rotating ring 22 drives the crescent block 24 to rotate, it also drives the metering ring 222 to rotate, so that the metering ring 222 is in a state of overlap with the arc block 131 at regular intervals, thereby realizing the timed closing of the mixing pipe 13. This ensures that the amount of added material delivered from the mixing pipe 13 to the mixing chamber 11 is constant, thus enabling small-volume addition multiple times and saving additional driving force.

[0051] Working principle of the invention:

[0052] According to the mixing ratio, the staff connects the main powder and the additive to the feed pipe 12 and the mixing pipe 13 respectively. Then, the main powder is conveyed to the mixing chamber 11 through the feed pipe 12. After the main powder enters the mixing chamber 11 through the feed pipe 12, the additive enters the mixing pipe 13. Then, the controller starts the motor in the power chamber 21. The drive shaft in the motor drives the transmission gear to rotate. During the rotation of the transmission gear, the transmission gear meshes with the transmission rotating gear 221. The rotating gear 221 rotates and drives the rotating ring 22 to rotate, so that the two rotating rings 22 rotate to opposite sides. During the rotation of the rotating ring 22, the rotating ring 22 drives the metering ring 222 to rotate. When the notch of the metering ring 222 coincides with the arc block 131, the feed port 132 is closed to the mixing chamber 11. When the notch of the metering ring 222 does not coincide with the arc block 131, the feed port 132 is connected to the mixing chamber 11, so that the additive can enter the mixing chamber 11 through the mixing pipe 13.

[0053] During the rotation of the rotating ring 22, the rotating ring 22 drives the crescent block 24 to rotate. The crescent block 24 rotates around the axis of the rotating ring 22. During the rotation of the crescent block 24, it pushes the powder in the mixing chamber 11. A part of the powder enters the stirring chamber 25 through the arc groove 26. While the crescent block 24 is rotating, it drives the stirring chamber 25 to rotate. The stirring chamber 25 revolves around the axis of the rotating ring 22. When the crescent block 24 rotates, it also drives the rotating shaft 27 to rotate. The rotating shaft 27 then rotates along the moving groove 231. Since the rotating shaft 27 is provided with a rotating gear 271 at the top, during the rotation of the rotating shaft 27 around the axis of the rotating ring 22, the rotating gear 271 meshes with the gear ring 23. The rotating gear 271 rotates along the axis of the rotating ring 22. During the rotation of the rotating gear 271, the side with the longer arc of the rotating gear 271 and the gear ring 23 moves to the side with the shorter arc of the other gear ring 23.

[0054] The rotating gear 271 then rotates under the action of the gear ring 23, causing the rotating gear 271 to rotate on its own axis. During the rotation of the rotating gear 271, it drives the rotation shaft 27 to rotate, which in turn drives the rotating shaft 272 to rotate. During the rotation of the rotating shaft 272, the rotating shaft 272 drives the spiral plate 28 to rotate within the mixing chamber 25. When the spiral plate 28 rotates, it drives the baffle 281 to rotate. The spiral plate 28 and the baffle 281 cooperate with each other to stir and mix the powder in the mixing chamber 25. During the mixing process, a portion of the powder moves into the hollow tube 282 under the action of the baffle 281. Under the action of centrifugal force, the powder is thrown to the next layer of baffle 281, so that the powder is fully mixed in the mixing chamber 25. After a period of mixing, the controller controls the outlet 14 to open, and the mixture is then conveyed through the mixing chamber 11 to the outlet 14 and discharged from the outlet 14. During the discharge process, the two crescent blocks 24 are still rotating, so that the crescent blocks 24 push the mixture to move.
