Description

Technical Field

[0001] This utility model relates to the field of chemical powder conveying technology, specifically to a chemical powder conveying device. Background Technology

[0002] In the complex systems of chemical production, powders, with their unique physicochemical properties, have become an indispensable key material form in many production stages. From basic raw material pretreatment to refined finished product preparation, powders are present almost throughout the entire process. For example, in catalyst production, powders with specific components are the core for forming highly efficient catalytic active centers; in the plastics processing industry, filler powders can significantly improve the mechanical properties and heat resistance of materials; and in pigment manufacturing, the particle size distribution and purity of powders directly determine the color saturation and stability of the final product. It can be said that the quality and application efficiency of powders profoundly affect the continuity of chemical production processes, energy consumption levels, and the market competitiveness of final products.

[0003] However, in the actual application of powders, the process of accurately adding them to reaction equipment faces many practical challenges. Currently, mainstream chemical reaction equipment, in order to improve reaction efficiency, facilitate material mixing, and meet safety production regulations, often places the feed inlet at a high position. While this design optimizes the internal environment of the reaction system to some extent, it significantly inconveniences the powder feeding operation. Operators need to use ladders, platforms, and other auxiliary tools to work at height, which not only increases labor intensity but also poses safety hazards during frequent handling and dumping. Even slight carelessness could lead to powder leaks, personnel falls, and other accidents.

[0004] More importantly, traditional manual feeding methods struggle to achieve precise control over the amount of powder added. Chemical reactions have extremely stringent requirements for material ratios; even minute dosage deviations can lead to incomplete reactions, increased byproducts, or even violent chemical reactions, causing equipment damage and product spoilage. During manual feeding, the actual amount of powder added often deviates significantly from the process requirements due to factors such as operator experience, physical limitations, and visual judgment errors. This "extensive" feeding method not only reduces production stability and repeatability but also increases subsequent separation and purification costs, severely hindering chemical companies' transition to refined and efficient production models. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a chemical powder conveying device.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a chemical powder conveying device, comprising a base, a support plate mounted on the base, a conveying cylinder mounted on the support plate, a rotating shaft rotatably mounted inside the conveying cylinder, a conveying auger mounted on the rotating shaft, a feeding port opened on the conveying cylinder, a feeding pipe mounted on the conveying cylinder, a metering box mounted on the feeding pipe, a discharge pipe mounted on the metering box, a storage bin mounted on the discharge pipe, an electrically controlled valve body provided on the discharge pipe, and a quantitative feeding mechanism provided on the metering box.

[0007] Preferably, the quantitative feeding mechanism includes a movable plate slidably installed inside the metering box, a metering plate slidably disposed on the movable plate, a pressure sensor installed on the movable plate, a microcontroller installed on the metering box, and a fixed scraper installed on the inner wall of the metering box.

[0008] Preferably, a support rod is installed on the movable plate, a screw sleeve is installed on the support rod, a screw rod is sleeved inside the screw sleeve, a drive motor is installed on the metering box, and the screw rod is installed at the output end of the drive motor.

[0009] Preferably, a guide rod is installed on the metering box, and a guide sleeve is installed at the bottom of the movable plate, with the guide sleeve slidably sleeved on the guide rod.

[0010] Preferably, anti-detachment blocks are installed on both the screw and the guide rod, a T-shaped limiting groove is provided on the movable plate, a T-shaped limiting block is installed on the metering plate, and the T-shaped limiting block is disposed in the T-shaped limiting groove.

[0011] Preferably, the storage silo is equipped with a cover and an observation window, and the cover has a feeding port.

[0012] Preferably, a conveying motor is installed at the end of the conveying cylinder, and the rotating shaft is installed at the output end of the conveying motor.

[0013] The beneficial effects achieved by this utility model are as follows:

[0014] 1. This utility model uses a pressure sensor to monitor the quality of powder on the metering plate in real time, and combines a microcontroller to precisely control the opening and closing timing of the electronic control valve to ensure that the quality of powder added each time meets the preset value, thus solving the problem of large measurement error when adding powder manually in the traditional method. In the quantitative feeding mechanism, the fixed scraper can scrape off excess powder on the metering plate, further ensuring the measurement accuracy, which is especially suitable for chemical reaction scenarios that are sensitive to the amount of material added.

[0015] 2. In this invention, a quantitative amount of powder is fed from the metering box into the feeding pipe, and then into the conveying cylinder through the feeding pipe. The rotation of the shaft drives the conveying auger to rotate, which in turn conveys the powder. The conveyed powder is then fed into the reaction equipment through the feeding port. The powder can be quantitatively added at any time as needed, making operation convenient. Automated control is achieved through components such as the drive motor, conveying motor, and microcontroller, reducing manual intervention. There is no need for personnel to climb to high positions to add powder, reducing operational risks and improving feeding efficiency, making it suitable for continuous production needs.

[0016] 3. The cooperation between the guide rod and the guide sleeve of this utility model ensures that the movable plate slides smoothly and avoids errors caused by shaking during the metering process; the T-shaped limit groove and the T-shaped limit block limit the horizontal displacement of the metering plate and ensure the accuracy of the pressure sensor monitoring data; the anti-detachment block prevents the movable plate from detaching from the screw or guide rod when sliding, thus improving the safety of equipment operation.

[0024] To better understand the purpose, structure, and function of this utility model, a chemical powder conveying device of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] like Figure 1-6 As shown, this embodiment provides a chemical powder conveying device, including a base 1, a support plate 2 installed on the base 1, a conveying cylinder 3 installed on the support plate 2, a rotating shaft 4 rotatably installed inside the conveying cylinder 3, a conveying auger 5 installed on the rotating shaft 4, a feeding port 6 opened on the conveying cylinder 3, a feeding pipe 7 installed on the conveying cylinder 3, a metering box 8 installed on the feeding pipe 7, a discharge pipe 9 installed on the metering box 8, a storage bin 10 installed on the discharge pipe 9, an electrically controlled valve body 11 installed on the discharge pipe 9, and a quantitative feeding mechanism 12 installed on the metering box 8. Powder is pre-added to the storage bin 10. When powder needs to be added, the quantitative feeding mechanism 12 will adjust the electrically controlled valve body 11 to open. At this time, the powder in the storage bin 10 will enter the metering box 8 through the discharge pipe 9, and then the powder in the metering box 8 will be quantitatively added by the quantitative feeding mechanism 12, while simultaneously controlling the electrically controlled valve body 11 to close to prevent the powder in the storage bin 10 from continuing to be released. A fixed amount of powder is fed from the metering box 8 into the feeding pipe 7, and then into the conveying cylinder 3. The rotation of the rotating shaft 4 drives the conveying auger 5 to rotate, which in turn conveys the powder. The conveyed powder is then fed into the reaction equipment through the feeding port 6, which can realize the quantitative feeding of powder. The powder can be quantitatively fed at any time as needed, making the operation relatively convenient.

[0026] Specifically, to achieve quantitative powder dispensing, the quantitative dispensing mechanism 12 includes a movable plate 121 slidably installed inside the metering box 8, a metering plate 122 slidably mounted on the movable plate 121, a pressure sensor 123 mounted on the movable plate 121, a microcontroller 124 mounted on the metering box 8, a fixed scraper 125 mounted on the inner wall of the metering box 8, a support rod 126 mounted on the movable plate 121, a screw sleeve 127 mounted on the support rod 126, a screw 129 sleeved inside the screw sleeve 127, a drive motor 128 mounted on the metering box 8, and the screw 129 mounted on the drive motor 128. The output of 28; when powder needs to be added, the microcontroller 124 will adjust the opening of the electronic control valve 11. At this time, the powder in the storage bin 10 will enter the metering box 8 through the feeding pipe 9, and then the powder in the metering box 8 will fall onto the metering plate 122. The pressure sensor 123 will monitor the mass of the powder on the metering plate 122. When the mass of the powder reaches the set amount, the microcontroller 124 will control the drive motor 128 and the conveying motor 16 to open, and control the electronic control valve 11 to close to prevent the powder in the storage bin 10 from continuing to be released. The rotation of the drive motor 128 will drive the screw 129 to rotate. The rotation of the screw 129 will drive the screw sleeve 127, the support rod 126, the movable plate 121, and the metering plate 122 to move forward. The moving metering plate 122 will cause the fixed scraper 125 to scrape the powder off the metering plate 122. The scraped powder will be fed from the metering box 8 into the feeding pipe 7, which can realize the quantitative addition of powder.

[0027] Furthermore, to guide the movement of the movable plate 121 and the measuring plate 122, a guide rod 1210 is installed on the measuring box 8, and a guide sleeve 1211 is installed at the bottom of the movable plate 121. The guide sleeve 1211 is slidably fitted onto the guide rod 1210. When the movable plate 121 and the measuring plate 122 are pulled out of the measuring box 8, the guide sleeve 1211 will slide on the guide rod 1210, which can guide the movement of the movable plate 121 and the measuring plate 122, so that the movable plate 121 and the measuring plate 122 can only move along the guide rod 1210.

[0028] Furthermore, to ensure the horizontal positioning of the measuring plate 122, anti-detachment blocks 1212 are installed on both the screw 129 and the guide rod 1210. A T-shaped limiting groove 1213 is provided on the movable plate 121, and a T-shaped limiting block 1214 is installed on the measuring plate 122, positioned within the T-shaped limiting groove 1213. The T-shaped limiting block 1214 slides within the T-shaped limiting groove 1213, thus limiting the horizontal position of the measuring plate 122 and preventing it from moving horizontally. Simultaneously, the measuring plate 122 rests against the pressure sensor 123, allowing pressure monitoring via the pressure sensor 123.

[0029] Furthermore, to facilitate the addition of powder to the storage silo 10, a cover 13 and an observation window 15 are installed on the storage silo 10. The cover 13 has a feeding port 14. Powder is added to the storage silo 10 in advance through the feeding port 14 on the cover 13, and the amount of powder in the storage silo 10 can be observed through the observation window 15 so that it can be added in time.

[0030] Furthermore, in order to drive the conveying auger 5 to rotate and convey the powder, a conveying motor 16 is installed at the end of the conveying cylinder 3, and a rotating shaft 4 is installed at the output end of the conveying motor 16; the rotation of the conveying motor 16 will drive the rotating shaft 4 to rotate, the rotation of the rotating shaft 4 will drive the conveying auger 5 to rotate, and the rotation of the conveying auger 5 will convey the powder.

[0031] Working principle: During use, powder is pre-added to the storage silo 10 through the feeding port 14 on the cover 13. The amount of powder in the storage silo 10 can be observed through the observation window 15 for timely replenishment. When powder needs to be added, the microcontroller 124 will adjust the opening of the electronic control valve 11. At this time, the powder in the storage silo 10 will enter the metering box 8 through the feeding pipe 9, and then fall onto the metering plate 122. The pressure sensor 123 will monitor the mass of the powder on the metering plate 122. When the mass of the powder reaches the set amount, the microcontroller 124 will control the drive motor 128 and the conveying motor 16 to start, and control the electronic control valve 11 to close to prevent the powder in the storage silo 10 from continuing to be released. The rotation of the drive motor 128 drives the screw 129 to rotate. The rotation of the screw 129 drives the screw sleeve 127, support rod 126, movable plate 121, and metering plate 122 to move forward. As the metering plate 122 moves forward, the fixed scraper 125 scrapes the powder off the metering plate 122. The scraped powder is fed from the metering box 8 into the feeding pipe 7 and then into the conveying cylinder 3. The rotation of the conveying motor 16 drives the rotating shaft 4 to rotate, which in turn drives the conveying auger 5 to rotate. The rotating conveying auger 5 conveys the powder, which is then fed into the reaction equipment through the feeding port 6. This allows for quantitative feeding of the powder, and the powder can be quantitatively fed at any time as needed, making the operation relatively convenient.
