Description

Technical Field

[0001] This invention relates to the field of pellet feeding, and in particular to an integrated pellet feeding device that combines weighing and discharging. Background Technology

[0002] In the production of spherical fuel elements for high-temperature gas-cooled reactors, precise control of particle content is a core technological requirement that directly determines the reactor's safety and performance. Therefore, in our company's automated expansion project of the pressing line, there is an urgent need for a multi-station, highly efficient method that can precisely control the particle feed rate.

[0003] In the existing production line process, the control of particle feeding amount mainly adopts the geometric volumetric measurement method, which measures the particles using a fixed-volume container. However, this method is greatly affected by the particle processing technology and cannot accurately and stably control the particle feeding amount. Currently, weight-based control is the optimal solution for optimizing particle content. However, the weight-based feeding method requires extremely high weighing accuracy. During the particle feeding process, multiple vibrations are easily generated, and the mutual influence between multiple stations can cause fluctuations and deviations in the weighing results. Summary of the Invention

[0004] This invention provides an integrated weighing and discharging particle feeding device to solve the problem of insufficient particle weight control and feeding accuracy in the prior art.

[0005] The technical solution of the present invention is as follows:

[0006] This invention proposes an integrated weighing and discharging particle feeding device. The device includes several vibrating feeding mechanisms, several particle weighing feeding mechanisms, and several conical receiving bowls. Each vibrating feeding mechanism and particle weighing feeding mechanism is positioned correspondingly. The particle weighing feeding mechanism is located below the discharge port of the vibrating feeding mechanism, and the particles are fed into the particle weighing feeding mechanism through the vibrating feeding mechanism. Each conical receiving bowl is located at the discharge port of each particle weighing feeding mechanism and is used to store the fed particles.

[0007] In some embodiments, the number of vibratory feeding mechanism, particle weighing and feeding mechanism and conical receiving bowl is six. The vibratory feeding mechanism is installed on the straight vibration mounting plate by bolt connection. The straight vibration mounting plate is connected to the transfer base plate. The transfer base plate is fixed on the crossbeam. The position of the crossbeam is higher than that of the weighing and feeding mechanism.

[0008] In some embodiments, a single-unit particle vibration feeding mechanism includes a triangular pipe, a valve plate, a feeding pipe, and a vibration motor. The outlet of the feeding pipe is connected to the inlet of the triangular pipe, and a vibration motor is provided at the lower end of the triangular pipe. The bottom of the vibration motor is connected to a direct vibration mounting plate. The valve plate is disposed inside the triangular pipe and is used to control the flow rate of the feeding particles inside the triangular pipe. The feeding particles are transported to the triangular pipe through the feeding pipe and enter the particle weighing and feeding mechanism through the outlet of the triangular pipe under the action of the vibration motor.

[0009] In some embodiments, the particle weighing and feeding mechanism is set on a marble platform. The particle weighing and feeding mechanism includes a U-shaped lifting plate, a particle container, a contour cone, a feeding funnel, a weighing component, and a support body. The weighing component is equipped with a support body and is used to calculate the weight of the feeding particles. The feeding funnel is installed on the support body. The feeding funnel has a contour cone inside. The feeding funnel and the particle container are nested together. The particle container is set above the feeding funnel. The U-shaped lifting plate is set on the outside of the particle container. The U-shaped lifting plate is controlled to move up and down by the lifting component. The U-shaped lifting plate drives the particle container to move up and down, realizing the insertion and separation of the particle container and the feeding funnel.

[0010] In some embodiments, the weighing component is mounted on a marble platform, the marble being used to attenuate the vibration energy generated during the feeding of the particles; a conical receiving bowl is provided below the feeding funnel.

[0011] In some embodiments, the pellet container is a hollow cylindrical structure, nested inside the discharge point. The pellet container and the contour cone form a discharge channel for the pellets. When the pellet container is nested inside the discharge point, the discharge channel is closed. When the pellet container is separated from the discharge point by the U-shaped lifting plate, the discharge channel is opened, and the pellets in the pellet container enter the discharge funnel.

[0012] In some embodiments, a protruding structure is provided on the upper outer wall of the pellet container. Under the drive of the lifting assembly, the U-shaped lifting plate lifts the protruding structure to realize the fitting and separation of the pellet container and the feeding funnel.

[0013] In some embodiments, the lifting assembly includes several columns, guide rails, a long arm connecting beam, a screw, a slider, and a servo motor. Several columns are set on a marble platform, guide rails and servo motors are set on the columns, sliders are set on the guide rails, the long arm connecting beam is connected to the sliders on the columns, and the servo motor drives the sliders to realize the up and down sliding of the long arm connecting beam. The long arm connecting beam is connected to a U-shaped lifting plate.

[0014] In some embodiments, the U-shaped lifting plate does not contact the particle container when the weighing assembly is weighing.

[0015] The implementation of this invention has the following beneficial effects:

[0016] This invention proposes an integrated particle feeding device that combines weighing and discharging. By setting up a particle vibration feeding mechanism and a particle weighing feeding mechanism, the device eliminates the influence of particle size and morphology fluctuations, solves the problem of inaccurate and unstable particle weighing control in the original production process, and enables multiple stations to simultaneously complete accurate particle weighing and discharging, greatly improving production efficiency.

Detailed Implementation

[0027] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. 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.

[0028] like Figures 1 to 9 As shown, this invention proposes an integrated weighing and discharging pellet feeding device, which consists of six sets of pellet vibrating feeding mechanisms 1, six sets of pellet weighing feeding mechanisms 2, six sets of conical receiving bowls 3, and a marble platform 4. Each vibrating feeding mechanism and pellet weighing feeding mechanism 2 is positioned correspondingly, with the weighing feeding mechanism 2 located below the discharge port of the vibrating feeding mechanism. The pellets are fed into the weighing feeding mechanism 2 through the vibrating feeding mechanism. The six sets of pellet weighing feeding mechanisms 2 are mounted on the marble platform 4 with screws. The device operates synchronously in a six-station configuration, ensuring a good positional relationship between the pellet vibrating feeding mechanism 1 and the pellet weighing feeding mechanism 2, guaranteeing smooth weighing and discharging of the pellets.

[0029] like Figure 2 As shown, six sets of particle vibration feeding mechanisms 1 are bolted to the vertical vibration mounting plate 6. The vertical vibration mounting plate 6 is fixed to the crossbeam 7 via a transition base plate 5. The crossbeam 7 is positioned higher than the weighing feeding mechanism. Each conical receiving bowl 3 is located at the discharge port of each particle weighing feeding mechanism 2 and is used to store the fed particles.

[0030] like Figure 5As shown, the single-unit particle vibrating feeding mechanism 1 includes a triangular pipe 14, a valve plate 15, a feeding pipe 16, and a vibrating motor 17. The outlet of the feeding pipe 16 is connected to the inlet of the triangular pipe 14. The vibrating motor 17 is located at the lower end of the triangular pipe 14, and the bottom of the vibrating motor 17 is connected to a vertical vibration mounting plate 6. Particles are transported through the feeding pipe 16 to the horizontally positioned triangular pipe 14, and under the action of the vibrating motor 17, they enter the particle weighing and feeding mechanism 2 through the end-side feeding port of the triangular pipe 14. The valve plate 15 is located inside the triangular pipe 14. During the feeding process, the position of the valve plate 15 can be adjusted by adjusting bolts, thereby controlling the particle flow rate. That is, particles will only enter the particle weighing and feeding mechanism 2 when the vibrating motor 17 is running.

[0031] like Figure 6 and 7 As shown, the particle weighing and feeding mechanism 2 includes a U-shaped lifting plate 21, a particle container 20, a contour cone 22, a feeding funnel 23, a weighing component, and a support body 19. The weighing component is equipped with the support body 19 and is used to calculate the weight of the fed particles. Particles from the particle weighing and feeding mechanism 2 fall into the particle container 20 under gravity, and the weighing component 18 can accurately weigh the fed particles. The feeding funnel 23 is installed on the support body 19. The feeding funnel 23 has a contour cone 22 inside. The feeding funnel 23 and the particle container 20 are nested together. The particle container 20 is located above the feeding funnel 23. The U-shaped lifting plate 21 is located on the outside of the particle container 20. The U-shaped lifting plate 21 is controlled by the lifting component to move up and down. The U-shaped lifting plate 21 drives the particle container 20 to move up and down, realizing the insertion and separation of the particle container 20 and the feeding funnel 23. A conical receiving bowl 3 is set below the feeding funnel 23.

[0032] The weighing components are specifically weighing sensors, branded Mettler Toledo, model WKC6002C6200g square weighing pan. To avoid the mutual disturbance of particles during the feeding process within the triangular pipe 14 between multiple stations affecting the accuracy of the weighing results, the weighing components 18 are all installed on the marble platform 4. Due to the high damping characteristics and low elastic modulus of marble, it can effectively attenuate the vibration energy generated during particle feeding, thereby ensuring the accuracy of the weighing results. In addition, marble has a low thermal conductivity and high heat capacity, which can effectively buffer the thermal stress caused by ambient temperature fluctuations, ensuring the long-term stability of the weighing.

[0033] The pellet container 20 is a hollow cylindrical structure, nested inside the discharge point. The pellet container 20 and the contoured cone 22 form a pellet discharge channel. When the pellet container 20 is nested inside the discharge point, the discharge channel is closed. When the pellet container 20 is separated from the discharge point by the U-shaped lifting plate 21, the discharge channel opens, and the pellets inside the pellet container 20 enter the discharge funnel 23. A protruding structure is provided on the upper outer wall of the pellet container 20. Driven by the lifting assembly, the U-shaped lifting plate 21 lifts the protruding structure, enabling the pellet container 20 to engage and disengage from the discharge funnel 23.

[0034] like Figure 3 As shown, the lifting assembly includes several columns 8, guide rails 9, a long arm connecting beam 10, a screw 11, a slider 12, and a servo motor 13. Several columns 8 are set on the marble platform 4, and the guide rails 9 and servo motor 13 are set on the columns 8. The slider 12 is set on the guide rails 9. The long arm connecting beam 10 is connected to the slider 12 on the columns 8. The long arm connecting beam 10 can be raised and lowered under the action of the servo motor 13, thereby driving the lifting plate installed on the long arm connecting beam 10 to move.

[0035] like Figure 8 As shown, the U-shaped lifting plate 21 is fixed to the long arm connecting beam 10 with screws. The particle container 20 is located in the middle of the U-shaped lifting plate 21. When the long arm connecting beam 10 moves upward, the U-shaped lifting plate 21 supports the outer edge of the particle container 20, thereby driving it to move upward. In the initial position of the particle weighing container lifting process, the particle container 20 fits well with the contour cone 22, and the particle falling channel is not open. When the particle container 20 is lifted upward under the action of the U-shaped lifting plate 21, the channel between the particle container 20 and the contour cone 22 opens, and the particles fall into the feeding funnel 23 under the action of gravity.

[0036] like Figure 4As shown, this invention proposes an integrated weighing and discharging particle feeding device. The specific workflow is as follows: Particles enter a horizontally positioned triangular pipe 14 through a feeding pipe 16 and fall into a particle container 20 under the action of a vibration motor 17. When the precision weighing component 18 detects that the particles have reached the required weight, it sends a real-time signal to control the vibration motor 17 to stop working, ensuring immediate cessation of particle feeding. A servo motor 13 drives the long-arm connecting beam 10 upwards, lifting the particle container 20 and opening the channel between it and the contour cone 22. The particles then fall into the feeding funnel 23 and into the conical receiving bowl 3, achieving precise quantitative feeding. In the particle weighing and feeding mechanism 2, during the process of particles falling from the triangular pipe 14 into the particle container 20, the U-shaped lifting plate 21 is in its initial position and does not contact the particle container 20, thus not affecting accurate weighing. In this embodiment, the multi-station design allows for simultaneous vibration, weighing, and feeding actions, ensuring efficient powder feeding while maintaining weighing.

[0037] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
