Description

Technical Field

[0001] This application relates to the field of powder metering technology, and in particular to an automatic fractionation and metering device. Background Technology

[0002] In the preparation and analysis of mineral and metal samples, it is often necessary to quantitatively dispense powders. In the past, this was commonly done manually. While this method effectively quantifies the materials, it is extremely inefficient due to its reliance on manual operation, especially in automated production lines. To address this, some existing technologies use belt scales for online conveying and quantitative dispensing. However, in actual production, the same equipment often handles multiple materials. Ensuring quantitative dispensing while maintaining cleanliness is also crucial. Existing quantitative dispensing equipment is inconvenient for online quantitative dispensing and cannot achieve rapid cleanliness. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] To address the aforementioned problems, this application provides an automatic fraction reduction and quantification device. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 and Figure 2 The automatic reduction and quantitative device shown includes a quantitative balance 6, and further includes:

[0034] Frame type frame 1, conical hopper 2, first vibrator 3, feeding pipe 4, second vibrator 5, first guide rail slider mechanism 8, cleaning and recycling pipe 9, negative pressure dust collector 10, second guide rail slider mechanism 11, rotating air nozzle cover 12.

[0035] A conical hopper 2 is fixedly installed at the top of the frame frame 1. A first vibrator 3 is installed on the conical surface of the conical hopper 2. A feeding pipe 4 is connected to the bottom outlet of the conical hopper 2. The feeding pipe 4 is L-shaped and a second vibrator 5 is connected to its bottom. A second guide rail slider mechanism 11 is connected to one side of the frame frame 1. A rotating air nozzle cover 12 is connected to the slider of the second guide rail slider mechanism 11 and covers the conical hopper 2 directly above it. A first guide rail slider mechanism 8 is connected to one side of the frame frame 1. An L-shaped cleaning and recycling pipe 9 is connected to the slider of the first guide rail slider mechanism 8. The cleaning and recycling pipe 9 and the feeding pipe 4 are coaxially arranged and can be connected to each other. The quantitative balance 6 is located directly below the connection between the cleaning and recycling pipe 9 and the feeding pipe 4. The cleaning and recycling pipe 9 is connected to the negative pressure dust collector 10 through a hose.

[0036] In this application, the material is poured into the conical hopper 2 and conveyed to the feeding pipe 4 by the vibration of the first vibrator 3. The material is vibrated and falls from one end of the feeding pipe 4 into the material cup 7 on the quantitative balance 6. This vibratory feeding process operates at two frequencies: first, a high frequency is used to quickly feed the material to 98% of the target weight, and then a lower frequency is used to slowly feed the remaining 2%. This method achieves rapid feeding while ensuring the accuracy of the target weight. In the production of components, the conical hopper 2, feeding pipe 4, and cleaning and recycling pipe 9, which come into contact with the material, are all made of stainless steel and polished using a stainless steel polishing process to avoid adhesion to the walls or affecting the flow of the material. The quantitative balance 6 of this application is a Mettler high-precision balance. When the vibratory feeder is working, it has a high-response dynamic feedback reading. A photoelectric sensor is equipped at the receiving position of the material cup 7 to monitor and reduce equipment malfunctions.

[0037] When the equipment is performing quantitative material weighing, the feeding pipe 4 and the cleaning and recovery pipe 9 are separate, forming a gap between them. The material falls into the quantitative balance 6 through the gap. When the material conveying is completed and the various components of the conveying process need to be cleaned, the second guide rail slider mechanism 11 drives the rotating air nozzle cover 12 to cover the conical hopper 2; at the same time, the first guide rail slider mechanism 8 drives the cleaning and recovery pipe 9 to connect with the feeding pipe 4. The rotating air nozzle cover 12 is equipped with rotating air nozzles connected to an air source to blow clean in a closed space, followed by negative pressure dust removal. The funnel in contact with the material is made of stainless steel and equipped with two vibrators to minimize material adhesion to the wall, reduce material loss, and avoid cross-contamination.

[0038] Thus, by configuring corresponding multi-degree-of-freedom robotic arms at the front and back ends of the quantitative conveying system, the robotic arms feed the material into the conical hopper 2 for quantitative weighing, and then the weighed material is transported away by the robotic arms. After the material in the conical hopper 2 is completely conveyed, it is cleaned. By configuring corresponding controllers to control the corresponding equipment to perform the actions, it is possible to achieve automatic online quantitative conveying while also achieving rapid cleaning.

[0039] This application uses a vibratory conveying system for feeding materials, a quantitative balance 6 for quantitative measurement, and a movable cleaning and recovery pipe 9 for cleaning after feeding, in conjunction with a negative pressure dust collector 10 and a rotating air nozzle cover 12. This allows for both quantitative conveying and rapid cleaning.

[0040] In one embodiment, to facilitate vibratory feeding, two first vibrators 3 are installed at the bottom of the conical hopper 2. Simultaneously, to facilitate feeding through the feeding pipe 4, a second vibrator 5 is separately installed on the feeding pipe 4, thus facilitating vibratory feeding of materials. Since the equipment is installed and used on a frame-type machine 1, vibration inevitably causes some fluctuations in the weighing of the quantitative balance 6. Therefore, a shock-absorbing buffer support is installed at the bottom of the quantitative balance 6, and a shock-absorbing buffer support is installed at the bottom of the second vibrator 5. In this way, the impact of vibration is minimized as much as possible through the buffer supports.

[0041] In one embodiment, such as Figure 4 and Figure 6 As shown, two openable baffles 85 are installed at the opening of the feeding pipe 4 to block the flow. During use, initially, the two baffles 85 are opened to quickly and in large quantities feed material. When 80% of the set amount is reached, the two baffles 85 block the opening of the feeding pipe 4, leaving a certain gap between the two baffles 85 so that the material can fall out from the gap, thereby slowing down the unit feed amount of the material to achieve accurate feeding.

[0042] In one embodiment, to facilitate the opening and closing control of the baffle 85 on the feed tube 4, such as Figures 3 to 6 As shown, there are two first guide rail slider mechanisms 8, namely guide rail slider mechanism 81 and guide rail slider mechanism 82. The slider of guide rail slider mechanism 82 is fixedly connected to the cleaning and recycling pipe 9. Two symmetrical connecting frames 83 are connected to the slider of guide rail slider mechanism 81 through connecting piece 86. One end of the connecting frame 83 is connected to an L-shaped connecting seat 84. One end of the L-shaped connecting seat 84 is connected to a baffle 85. The other end of the L-shaped connecting seat is connected to a spring 87. A connector for connecting to the feeding pipe 4 is provided at the end of the cleaning and recycling pipe 9. The cleaning and recycling pipe 9 and the feeding pipe 4 are of the same diameter.

[0043] Thus, when the feeding pipe 4 is discharging material normally, the second guide rail slider mechanism 82 moves to disengage the feeding pipe 4 from the joint of the cleaning and recycling pipe 9. At the same time, the first guide rail slider mechanism 81 also drives the connecting frame 83, carrying the baffle 85, to disengage from the feeding pipe 4, and the feeding pipe 4 is opened for normal material discharge. When the material channel reaches 80% of its set value, the first guide rail slider mechanism 81 drives the connecting frame 83, carrying the baffle 85, to block the feeding pipe 4, so that the material can only fall through the gap between the two baffles 85. After the quantitative conveying is completed, the vibrator stops. When the next quantitative conveying begins, the first guide rail slider mechanism 81 drives the connecting frame 83, carrying the baffle 85, to open. This process is repeated until all the material has been quantitatively conveyed. In this process, since the L-shaped connecting seat 84 is transferred at the connecting frame 83, a spring 87 connected to the other end of the L-shaped connecting seat 84 pulls the baffle 85, giving it a certain pressure when it contacts the feeding pipe 4. Simultaneously, during cleaning, when the feeding pipe 4 aligns with the cleaning and recycling pipe 9, the baffle 85 is pushed open by the joint of the cleaning and recycling pipe 9, allowing the feeding pipe 4 and the cleaning and recycling pipe 9 to connect. When the cleaning and recycling pipe 9 returns to its original position, the baffle 85 also returns to its original position thanks to the spring 87. Thus, the cooperation of the two guide rail slider mechanisms allows the cleaning and recycling pipe 9 and the feeding pipe 4 to open and close and adjust the amount of material falling, thereby optimizing and controlling the precise delivery of materials and facilitating subsequent rapid cleaning.

[0044] In one embodiment, in order to facilitate stable feeding of material through vibration while feeding material through the feeding pipe 4, a connecting plate 41 is provided at the bend of the feeding pipe 4, and the connecting plate 41 is screwed to the second vibrator 5.
