Description

Technical Field

[0001] This invention relates to the field of material conveying, and more particularly to a distributor and an automatic uniform mixing device using the same. Background Technology

[0002] Existing mixers cannot simultaneously achieve both uniform mixing and high-efficiency mixing. If different materials need to be mixed evenly, more time is required to fully agitate them. Therefore, existing mixers require a significant amount of time to mix different materials evenly, inevitably resulting in low efficiency. Conversely, while shortening the mixing time improves efficiency, it can lead to poor mixing results.

[0003] In the existing technology CN116651255A, the spiral blades and cylinder of the mixer cooperate with each other. During the rotation of the cylinder, it not only pushes the mixture forward, but also enables the mixture to tumble and mix itself, achieving uniform mixing in the spiral channel. "Uniform mixing" means that, under the premise that the types of additives and the input amount per unit time remain unchanged, the proportion of different materials in the final mixture output by the mixer at any time is the same or nearly the same, and the different materials are evenly distributed throughout the mixture.

[0004] Meanwhile, in order to ensure a uniform mixing effect, the existing technology CN116651255A uses an auger to transport the material in the transition conveying pipe 312. Since it is impossible to determine whether the material in the transition conveying pipe 312 is fully or half full, it is impossible to determine and accurately control the quality of the material entering the mixer 3 per unit time.

[0005] Therefore, the existing feeding mechanism needs to be improved to ensure that the quality of the material entering each time is accurate and reliable, so as to achieve uninterrupted feeding and discharging while ensuring uniform mixing. Summary of the Invention

The technical problems it solves are: (1) In the prior art, the quality and proportion of the material fed into the mixer cannot be effectively controlled, resulting in the inability to achieve uniform mixing. (2) In the prior art, when the mixer is combined with the conveying pipe, it is not possible to easily and effectively switch between the feeding mode and the feeding-mixing-feeding mode.

At this time, the first or second collecting section completely blocks the inlet to prevent material from entering the cylindrical cavity. When the load cell reading reaches G (G > 0), it indicates that the material in the weighing chamber can fill the first or second collecting section.

Detailed Implementation

[0025] The following is combined with Figures 1 to 9 The present invention will be further described as follows: like Figure 1-2 As shown, an automatic mixing device combined with a conveying pipe includes a conveying pipe 11 for conveying materials. Material A is conveyed in the conveying pipe 11 via an auger or chain conveyor. The conveying pipe 11 is located above the mixing cylinder 1. Material A in the conveying pipe 11 enters the weighing device 3, the distributor 4, and the mixing cylinder 1 sequentially from the discharge port 112. The material additive 5 directly conveys material B to the mixing cylinder 1 or conveys material B to the distributor 4 to mix with material A before conveying it to the mixing cylinder 1. Material A and material B enter from one end of the mixing cylinder 1, are uniformly stirred, and then output as a uniform mixture from the other end. The uniform mixture returns to the conveying pipe 11 through the material lifting channel 6, and the conveying pipe 11 conveys the uniform mixture to its destination.

[0026] Material A can be a solid material or a mixture of multiple materials. Material B can also be a solid material or a mixture of multiple materials. Material B can also be a liquid material or a solid-liquid mixture.

[0027] A temporary storage unit 8 is connected above the weighing device 3. The temporary storage unit 8 can store material A, allowing the conveying pipe 11 to continuously convey material A and preventing the processing capacity of the weighing device 3 and the distributor 4 from being insufficient to meet the conveying capacity of the conveying pipe 11. A valve is provided at the bottom of the temporary storage unit 8. The material outlet of the temporary storage unit 8 is located above the weighing device inlet 33. The temporary storage unit 8 includes a temporary storage chamber, and a valve is provided at the bottom of the temporary storage chamber. The valve includes a valve motor and a rotating blade. When the valve motor drives the rotating blade to be arranged horizontally, the bottom of the temporary storage chamber is closed; when the valve motor drives the rotating blade to be arranged vertically, the bottom of the temporary storage chamber is opened.

[0028] The temporary storage device 8 is connected to the crusher 2, which is used to crush the material A coming from the feed port 112. The crusher 2 includes a crushing motor 21, a first crushing wheel 24 and a second crushing wheel 25. The first crushing wheel 24 is connected to the first transmission gear 22, and the second crushing wheel 25 is connected to the second transmission gear 23. The two transmission gears mesh with each other, causing the first crushing wheel 24 and the second crushing wheel 25 to rotate in opposite directions. The crushing motor 21 is connected to the transmission shaft of the first crushing wheel 24 or the second crushing wheel 25 through a transmission mechanism or directly. The crushing teeth on the first crushing wheel 24 and the second crushing wheel 25 are staggered to ensure the crushing effect.

[0029] The material feeder 5 includes a hopper, a feeding motor, a feeding pipe, and a feeding auger. The shaft of the feeding motor is connected to the feeding auger, which extends in the feeding pipe.

[0030] When the outlet of the feeding pipe is located in the distributor 4, and the first collecting part 44 or the second collecting part 45 rotates to the position of receiving material from the inlet 47, the feeding motor starts, and the feeding pipe outputs material B to the first collecting part 44 or the second collecting part 45; or, when the outlet of the feeding pipe is located on the mixing cylinder 1, and the first collecting part 44 or the second collecting part 45 rotates to the position of outputting material from the outlet 42, the feeding motor starts, and the feeding pipe outputs material B to the mixing cylinder 1.

[0031] The upper end of the spiral auger 64 is higher than the conveying pipe 11, and the connection between the upper end of the spiral auger 64 and the conveying pipe 11 is made by an inclined pipe.

[0032] like Figure 3As shown, the material lifting channel 6 has a first structure: A spiral auger 64 is installed in the material lifting channel 6. The upper end of the spiral auger 64 is connected to the lifting motor 61 via an upper transmission mechanism 62 or directly. The lower end of the spiral auger 64 is located on one side of the discharge port of the mixing cylinder 1. The discharge port of the mixing cylinder 1 guides the uniformly mixed material into the working area of ​​the spiral auger 64 through the discharge slope 13. Under its own gravity, the uniformly mixed material can move to the working area of ​​the spiral auger 64 via the discharge slope 13. like Figure 4 As shown, the material lifting channel 6 has a second structure: the material lifting channel 6 is equipped with a spiral auger 64. The upper end of the spiral auger 64 is connected to the lifting motor 61 through the upper transmission mechanism 62 or directly. The lower end of the spiral auger 64 is connected to the pushing rotating shaft 68 through the lower transmission mechanism 63. The pushing rotating shaft 68 is equipped with a rotating pushing blade 65. The rotating pushing blade 65 is located below the discharge port of the mixing cylinder 1. The rotating pushing blade 65 can not only push the falling mixture to the spiral auger 64, but also the rotating pushing blade 65 and the spiral auger 64 work synchronously under the action of the lifting motor 61.

[0033] The right closed support plate 66 is connected to the pusher rotating shaft 68 via a bearing and is located below the rotating pusher plate 65. The spiral auger 64 is also connected to the left closed support plate 67 via a bearing. Material A falls onto the right closed support plate 66 and is pushed onto the left closed support plate 67 by the rotating pusher plate 65 for transmission by the spiral auger 64.

[0034] like Figure 5 and Figure 6 As shown, a switching valve 7 is installed at the discharge port 112 of the conveying pipe 11. When the switching valve 7 is open, the material A in the conveying pipe 11 can enter the mixing cylinder 1 through the weighing device 3; when the switching valve 7 is closed, the material A in the conveying pipe 11 does not enter the mixing cylinder 1 and is directly conveyed to the destination.

[0035] The switching valve 7 includes a rotating tube 75 and a drive mechanism. The rotating tube 75 has an opening 76, and the corresponding conveying pipe 11 has a downward-facing discharge port 112. The rotating tube 75 is fitted onto the conveying pipe 11. The drive mechanism causes the rotating tube 75 to rotate. When the rotating tube 75 rotates to the point where the opening 76 faces downward and is connected to the discharge port 112, material A can fall out of the conveying pipe 11. When the rotating tube 75 rotates to the point where the opening 76 faces upward and is not connected to the discharge port 112, material A can... It can be directly conveyed in the conveying pipe 11; the driving mechanism includes a switching motor 71, an upper gear 72 and a lower gear 73. The lower gear 73 is provided with a passage hole for the conveying pipe 11 to pass through. The rotating pipe 75 is connected to the lower gear 73. The upper gear 72 meshes with the lower gear 73. The rotating shaft of the switching motor 71 is connected to the upper gear 72. The switching motor 71 drives the upper gear 72 to rotate. The upper gear 72 causes the rotating pipe 75 to rotate through the lower gear 73, thereby opening or closing the discharge port 112 of the conveying pipe 11.

[0036] like Figures 7-9 As shown, a distributor that outputs the same mass of material to a mixing cylinder 1 each time is characterized by: a horizontally arranged cylindrical cavity 48, with an inlet 47 and an outlet 42 at its upper and lower ends, respectively; a distribution shaft 43 horizontally arranged in the cylindrical cavity 48; the distribution shaft 43 being connected to a distribution rotating partition to form at least a first collecting part 44 and a second collecting part 45 capable of rotation; the distribution shaft 43 being connected to the shaft of a distribution motor 41 via a transmission mechanism or directly; when the first collecting part 44 rotates to a position receiving material from the inlet 47, the second collecting part 45 is positioned to output material from the outlet 42; the first collecting part 44 or the second collecting part 45 can also rotate to completely block the inlet 47 to prevent material from entering the cylindrical cavity 48.

[0037] The upper end of the distributor is connected to the weighing device 3, which can weigh the material A in the weighing device 3 and the distributor 4. The weighing device 3 includes a weighing chamber, with a weighing inlet 33 and a weighing outlet 34 at its upper and lower ends, respectively. The weighing outlet 34 is connected to the inlet 47 of the distributor 4. The support part 32 supports the weight of the weighing device 3 and the distributor 4, and the weighing sensor 31 on the support part 32 can sense the changes in the material in the weighing device 3 and the distributor 4. The weighing device 3 is connected to the support part 32 through the weighing sensor 31. When the load cell 31 does not reach GG > 0, it indicates that the material in the weighing chamber cannot fill the first collection section 44 or the second collection section 45. At this time, the first collection section 44 or the second collection section 45 completely blocks the inlet 47 to prevent the material from entering the cylindrical cavity 48. When the load cell 31 reaches GG > 0, it indicates that the material in the weighing chamber can fill the first collection section 44 or the second collection section 45. The dispensing motor 41 is started to make the first collection section 44 or the second collection section 45 rotate to the position of receiving material from the inlet 47. After T seconds, the dispensing motor 41 is started again to make the first collection section 44 or the second collection section 45 rotate to the position of outputting material from the outlet 42.

[0038] This invention includes numerous transmission mechanisms: a transmission mechanism between the material distribution shaft 43 and the shaft of the material distribution motor 41; a transmission mechanism between the crushing motor 21 and the transmission shaft of the first crushing wheel 24 or the second crushing wheel 25; an upper transmission mechanism 62 between one end of the auger 64 and the lifting motor 61; a lower transmission mechanism 63 between the other end of the auger 64 and the pushing rotating shaft 68; and a transmission mechanism between the mixing blades and the mixing motor 12. Specifically, the transmission mechanism can utilize at least two pulleys and a transmission belt. One pulley is connected to the motor shaft, and the other pulley is connected to another component. The two pulleys are driven by the transmission belt. Besides belt drive, gear drive or sprocket drive can also be used as alternatives.

[0039] It also includes a control circuit, which is electrically connected to the weighing sensor 31, the dispensing motor 41, the lifting motor 61, the material feeder 5, and the switching valve 7. The control circuit is configured to: receive the signal from the weighing sensor 31 and control the start and stop of the dispensing motor 41 according to the signal to realize the rotation of the first collection section 44 or the second collection section 45; control the start and stop of the material feeder 5 to adjust the amount of material B added; control the opening and closing state of the switching valve 7 to switch the conveying mode of the conveying pipe 11; and control the start and stop of the lifting motor 61 to adjust the working state of the material lifting channel 6.

[0040] The control circuit also includes a human-machine interface for inputting the mixing ratio parameters of material A and material B, and automatically adjusting the working frequency of the distributor 4 and the material adder 5 according to the input parameters.

[0041] The control circuit also includes an alarm module. When the weighing sensor 31 detects an abnormality in the material or a blockage in the distributor 4, it triggers an alarm signal and stops the operation of the relevant equipment.
