Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to an auxiliary feeding device for a reaction vessel. Background Technology

[0002] Reactors are widely used in industries such as chemical, pharmaceutical, food, and bio-fermentation, and mainly undertake the important tasks of physical mixing and chemical reaction.

[0003] Currently, depending on the production process, liquid reactants are generally added to the reactor, or solid and liquid reactants are added in separate proportions. When the added solid reactants have not been calcined and dried, moisture is present in the reactants. In addition, the reactants themselves are sticky, so some material will adhere to the surface of the feeding hopper during the production process. To deal with this situation, some feeding hoppers are equipped with vibrating hammers. However, the hammering will cause vibration and noise pollution, and some material far from the hammer's striking point will still adhere, requiring regular manual inspection and handling, which wastes labor costs. Utility Model Content

[0004] The present invention aims to provide an auxiliary feeding device for a reaction vessel, which solves the problem of material adhesion, eliminates the need for regular manual inspection and handling, and saves labor costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An auxiliary feeding device for a reactor includes a feeding hopper body. The feeding hopper body is equipped with a driving device, which is connected to a feeding assembly. The feeding assembly includes an upper connecting plate, a feeding arm cylinder connected to the upper connecting plate, and a lower connecting plate connected to the telescopic end of the feeding arm cylinder. The lower connecting plate has a first sliding hole and a second sliding hole arranged opposite to each other. A brush plate is slidably connected in the first sliding hole, and a distribution plate is slidably connected in the second sliding hole. Both the distribution plate and the brush plate have latches connected to their opposite sides near the bottom edge. A clamping plate is slidably connected to the middle of the lower connecting plate, and the clamping plate is located between the brushing plate and the distributing plate. The side of the clamping plate near the brushing plate is rotatably connected to a limiting plate via a connector. The rotation range of the limiting plate is above the horizontal plane where the connector is located. The lower connecting plate is equipped with a clamping plate cylinder, which is used to drive the clamping plate to slide towards the brushing plate or towards the distributing plate. Several springs are connected to the top of the distributing plate and the top of the brushing plate, and the free ends of the springs are all connected to the lower connecting plate.

[0007] Furthermore, the driving device includes a ball screw rotatably connected to the feeding bin body. The ball screw is threadedly connected to a screw nut, which is fastened to the upper connecting plate. The upper connecting plate is fastened to a slider. The feeding bin body is connected to a sliding rod, and the slider is slidably connected to the sliding rod. The feeding bin body is equipped with a servo motor for driving the ball screw to rotate. When the ball screw rotates, the upper connecting plate moves linearly along the axial direction of the ball screw.

[0008] Furthermore, the first sliding hole includes a brush plate hole and a second groove that are interconnected, the second sliding hole includes a distribution plate hole and a first groove that are interconnected, the size of the brush plate hole is adapted to the brush plate, the size of the distribution plate hole is adapted to the distribution plate, and the sizes of the first groove and the second groove are adapted to the buckle.

[0009] Furthermore, the width of the card plate is greater than the width of the second groove, and the width of the limiting plate is greater than the width of the first groove.

[0010] Furthermore, the connector is a hinge.

[0011] Beneficial effects of the technical solution:

[0012] This invention combines a material distribution plate and a material brushing plate into one unit. The switching between the two plates is achieved through the action of a clamping cylinder.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0020] like Figure 1-4 As shown, an auxiliary feeding device for a reactor includes a feeding hopper body, which includes a support frame 5. The support frame 5 has a hopper, and the feeding hopper body has a driving device. The driving device is connected to a feeding assembly, which includes an upper connecting plate 9. In this embodiment, the driving device includes a ball screw 3 rotatably connected to the feeding hopper body via a fixed bearing seat 4. The ball screw 3 is threadedly connected to a screw nut 8, which is fastened to the upper connecting plate 9. A slider 7 is fastened to the upper connecting plate 9. The feeding hopper body is connected to a sliding rod 6, and the slider 7 is slidably connected to the sliding rod 6. The feeding hopper body is connected to a servo motor 1 for driving the ball screw 3 to rotate via a motor support 2. When the ball screw 3 rotates, the upper connecting plate 9 moves linearly along the axial direction of the ball screw 3. Both ends of the ball screw 3 are rotatably connected to the feeding hopper body via fixed bearing seats 4. Next, both fixed bearing seats 4 are connected to limit photoelectric sensors 18, and the upper connecting plate 9 is connected to two reflectors 19. Specifically, as a safety guarantee, photoelectric switches are connected in series with the control circuit of the servo motor 1. When the feeding device of the present invention drives the feeding component to push and brush material back and forth, in order to avoid the feeding component exceeding the preset position due to intermittent program failure, thereby causing collision and deformation of the mechanism support 5 or damage to the thread of the ball screw 3, limit photoelectric sensors 18 are provided at both ends of the fixed bearing seats 4, and reflectors 19 are provided on the upper connecting plate 9 of the feeding component running part. When the feeding component does not exceed the preset program position, the limit photoelectric sensors 18 do not act. However, when the feeding component exceeds the preset position, the limit photoelectric sensors 18 detect that the distance of the reflected light is less than the safe distance, the limit photoelectric sensors 18 act, cut off the running signal of the servo motor 1, the servo motor 1 stops running, and an alarm is triggered.

[0021] The upper connecting plate 9 is connected to the feeding arm cylinder 10. The telescopic end of the feeding arm cylinder 10 is connected to the lower connecting plate 11. The lower connecting plate 11 is provided with a first sliding hole and a second sliding hole arranged opposite to each other. A brush plate 13 is slidably connected in the first sliding hole, and a distribution plate 12 is slidably connected in the second sliding hole. Two first springs 15 are connected to the top of the distribution plate 12, and two second springs 14 are connected to the top of the brush plate 13. The free ends of the first springs 15 and the free ends of the second springs 14 are both connected to the lower connecting plate 11.

[0022] Both the material distribution plate 12 and the brush plate 13 have latches connected to their respective sides near the bottom edge. Specifically, the material distribution plate 12 has a first latch 1201 connected to its bottom edge near the brush plate 13, and the brush plate 13 has a second latch 1301 connected to its bottom edge near the material distribution plate 12. The first sliding hole includes a brush plate hole 1101 and a second groove 1103 that are interconnected. The second sliding hole includes a material distribution plate hole 1102 and a second groove that are interconnected. The dimensions of the first groove 1104 and the brush plate hole 1101 are adapted to the brush plate 13. The dimensions of the second groove 1103 are adapted to the second buckle 1301. The dimensions of the distributing plate hole 1102 are adapted to the distributing plate 12. The dimensions of the first groove 1104 are adapted to the first buckle 1201. These can be small-gap fits to prevent the brush plate 13 from wobbling during brushing and the distributing plate 12 from wobbling during distributing, ensuring the stability of the device. A retaining plate 16 is slidably connected to the middle of the lower connecting plate 11, and the retaining plate 16 is located at... Between the brush plate 13 and the dispensing plate 12, the side of the clamping plate 16 near the brush plate 13 is rotatably connected to the limiting plate 1601 via a hinge 1603. The rotation range of the limiting plate 1601 is above the horizontal plane where the connecting parts are located, so that when the brush plate 13 slides upward relative to the lower connecting plate 11, it can push the limiting plate 1601 to rotate upward. When the pushing force is removed, the hinge can automatically rotate to the horizontal position under the action of gravity and will not rotate downward again, thereby supporting the brush plate 13 and preventing the brush plate 13 from continuing to slide upward relative to the lower connecting plate 11. The lower connecting plate 11 slides downward; and the connecting plate is provided with a clamping cylinder 17, which is used to drive the clamping plate 16 to slide towards the brush plate 13 or towards the distributing plate 12; along the length direction of the first sliding hole or the second sliding hole, the width of the clamping plate 16 is greater than the width of the second groove 1103, and the width of the limiting plate 1601 is greater than the width of the first groove 1104, so that the clamping plate 16 can stably clamp the second buckle 1301 on the brush plate 13 and the first buckle 1201 on the distributing plate 12.

[0023] Working principle and specific implementation process:

[0024] During the material preparation stage, the telescopic end of the clamping plate cylinder 17 extends and remains extended. The clamping plate cylinder 16 pushes the clamping plate 16 towards the brush plate 13, causing the first groove 1104 to protrude from the side of the clamping plate 16 near the distributing plate 12, allowing the first latch 1201 to slide freely up and down. At the same time, the limiting plate 1601 closes the second groove 1103. The telescopic end of the feeding arm cylinder 10 extends downward, and the lower connecting plate 11 drives the distributing plate 12 and the brush plate 13 to move downward together. After the distributing plate 12 and the brush plate 13 touch the bottom, the telescopic end of the feeding arm cylinder 10 continues to extend, and the lower connecting plate 11 continues to move downward and compress the first spring 15 and the second spring 14. That is, the distributing plate 12 and the brush plate 13 move upward relative to the lower connecting plate 11. The second latch 1301 of the brush plate 13 pushes open the limiting plate 1601. When the lower connecting plate 11 continues to move downward (when the brush plate 13 continues to move upward relative to the lower connecting plate 11), the limiting plate 1601 is reset due to disengagement from the second latch 1301. The telescopic end of the feeding arm cylinder 10 reaches its maximum extension stroke and begins to retract. The distributing plate 12 and the brush plate 13 are reset relative to the lower connecting plate 11 under the elastic force of the first spring 15 and the second spring 14. Since the limiting plate 1601 cannot continue to rotate downward, the limiting plate 1601 locks the brush plate 13 to stop it from falling. The telescopic end of the locking plate cylinder 17 is in the pushed-out state. The distributing plate 12 continues to fall without obstruction until it is reset. At this time, the preparation work for retrieving the brush plate 13 and extending the distributing plate 12 is completed.

[0025] During the feeding stage, servo motor 1 drives ball screw 3 to move the entire feeding assembly along the axis of ball screw 3. According to the program, it stops after moving forward a certain distance and waits for the extension end of feeding arm cylinder 10 to extend, driving the entire feeding assembly downward. The material distribution plate 12 cuts the material. After the extension end of feeding arm cylinder 10 extends, it remains in the extended state. Servo motor 1 continues to drive ball screw 3 to move the entire feeding assembly forward until the material is pushed to the discharge port. The extension end of feeding arm cylinder 10 retracts, driving the entire feeding assembly upward. Servo motor 1 reverses and drives ball screw 3 to move the feeding assembly in the opposite direction. According to the program, it runs to the next material distribution position and stops. The extension end of feeding arm cylinder 10 extends again, and the previous steps are repeated until all the material is pushed out. Then the feeding assembly returns to the initial position, and the extension end of feeding arm cylinder 10 retracts.

[0026] During the preparation stage for cleaning up residual material, the telescopic end of the feeding arm cylinder 10 extends downward, and the entire feeding assembly moves downward until the material distribution plate 12 touches the bottom. The lower connecting plate 11 continues to move downward, meaning the material distribution plate 12 moves upward relative to the lower connecting plate 11. The first latch 1201 of the material distribution plate 12 passes through the position of the clamping plate 16. At this time, the telescopic end of the clamping plate cylinder 17 is in the extended state, and the right side 1602 of the clamping plate 16 retracts (the side of the clamping plate 16 closest to the material distribution plate 12 is defined as the right side 1602, meaning there is a gap between the right side 1602 of the clamping plate 16 and the first groove 1104 to allow the first latch 1201 to pass through). The material distribution plate 12 continues to move upward without being blocked by the clamping plate 16 until the telescopic end of the feeding arm cylinder 10 is fully extended. At this time, the telescopic end of the clamping plate cylinder 17 retracts. The slide plate moves towards the material distribution plate 12, blocking the first groove 1104 and holding it in place. The material distribution plate 12 and the brushing plate 13 return to their original positions relative to the connecting plate under the elastic force of the first spring 15 and the second spring 14. Since the right side 1602 of the clamping plate 16 extends as the extension end of the clamping plate 16 cylinder returns to its original position, the first latch 1201 of the material distribution plate 12 is blocked by the second clamping plate 16, and the material distribution plate 12 does not fall relative to the lower connecting plate 11. The brushing plate 13 retracts as the limiting plate 1601 retracts as the extension end of the clamping plate 16 cylinder returns to its original position. The second latch 1301 of the brushing plate 13 is not blocked by the limiting plate 1601 and continues to fall relative to the lower connecting plate 11 until it returns to its original position. At this time, the switching of the feeding arm from the material distribution plate 12 to the brushing plate 13 is completed.

[0027] During the residual material cleaning stage, the telescopic end of the feeding arm cylinder 10 extends downward and remains extended, pushing the entire feeding assembly downward. The brush of the brush plate 13 contacts the material bin of the feeding bin body. The servo motor 1 drives the ball screw 3 to move the entire feeding assembly along the axis of the ball screw 3 until the residual material is pushed and swept to the discharge port. The telescopic end of the feeding arm cylinder 10 retracts, and the servo motor 1 reverses to drive the ball screw 3 to move the feeding arm in the opposite direction, returning to the initial position. The previous steps are repeated until the feeding bin is completely cleaned and the feeding arm returns to the initial position.

[0028] In summary, this utility model combines the material distribution plate 12 and the material brushing plate 13 into one unit. The switching between the material distribution plate 12 and the material brushing plate 13 is achieved through the action of the clamping cylinder 17. Different plates are used for different operations at different stages. During the feeding stage, the material distribution plate 12 is used to cut the material in the rectangular hopper and push it to the discharge port. During the residual material cleaning stage, the material distribution plate 12 is retracted and switched to the material brushing plate 13. The brush head on the edge of the material brushing plate 13 brushes off the attached material and pushes it to the discharge port. The automation level is high, the material adhesion problem is solved, and there is no need for manual inspection and manual handling at regular intervals, saving labor costs.
