Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a novel feeding device for an antioxidant production reactor. Background Technology

[0002] In the production of antioxidants, the reaction vessel can provide a closed and controlled reaction environment to ensure that the chemical reaction takes place under specific conditions, thereby obtaining high-quality antioxidants;

[0003] When producing antioxidants in a reactor, strict raw material ratios and reaction conditions are required. Quantitative or timed feeding via a hopper allows for precise control of the input amount, ensuring reaction stability and product quality. Adding materials to the reactor via a hopper requires a control mechanism to open the hopper valve, allowing the material to enter the reactor through the valve at the bottom of the hopper. Therefore, when feeding powdery or small-particle materials, blockage can easily occur in the hopper. Some hoppers incorporate stirring mechanisms to prevent blockage during feeding, but this increases the overall structural cost of the hopper, makes it difficult to ensure synchronization between the stirring mechanism and the feeding valve, and can lead to uneven mixing of multiple materials during feeding. Utility Model Content

[0004] The purpose of this invention is to provide a novel feeding device for an antioxidant production reactor, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel feeding device for an antioxidant production reactor includes a feeding hopper. A sleeve is disposed in the center of the feeding hopper. Multiple support plates are fixedly connected to the outer side of the sleeve and to the feeding hopper. A flow guide is fixedly mounted on each of the support plates. A motor is fixedly mounted on the flow guide and electrically connected to an external main controller via a connecting wire. A rotating shaft is fixedly mounted at the output end of the motor. The rotating shaft extends through the sleeve to the lower part of the feeding hopper. A propeller blade is fixedly mounted on the rotating shaft below the sleeve. A first flange is fixedly mounted at the lower end of the feeding hopper. A second flange is fixedly mounted at the lower end of the first flange. A third flange is fixedly mounted between the first and second flanges. A fixed conical cover is fixedly mounted inside the third flange and is located within the feeding hopper. A movable conical cover is movably mounted on the fixed conical cover.

[0007] As a further preferred embodiment of this utility model, a bearing seat is provided in the middle of the sleeve, and multiple connecting plates are fixedly connected between the outer side of the bearing seat and the sleeve, and the rotating shaft is inserted into the bearing seat;

[0008] Therefore, by using the bearing seat, the rotating shaft can rotate more stably.

[0009] As a further preferred embodiment of this utility model, the fixed conical mask has two first discharge ports, and a shaft groove is provided in the middle of the fixed conical mask located between the two first discharge ports.

[0010] As a further preferred embodiment of this utility model, a connecting ring is fixedly installed on the outer side of the fixed cone cover, and the connecting ring is fixedly installed on the inner side of the third flange.

[0011] Based on this, two first discharge ports are opened inside the fixed cone-shaped cover, which allows the material in the feeding hopper to enter the reactor through the first discharge ports.

[0012] As a further preferred embodiment of this utility model, the movable cone-shaped cover has multiple second discharge ports, and the lateral contour of the second discharge port is the same as that of the first discharge port.

[0013] As a further preferred embodiment of this utility model, a bushing is fixedly installed in the middle of the movable conical cover, a spline hole is opened in the bushing, the movable conical cover is rotatably connected to the fixed conical cover, and the spline hole and the shaft groove are connected by a channel.

[0014] Based on this, the rotation of the rotating shaft can drive the movable conical cover to rotate on the fixed conical cover, thereby aligning the second discharge port with the first discharge port to realize material feeding. The misalignment of the first and second discharge ports can automatically stop the feeding, and the propeller blades can simultaneously agitate the material in the feeding hopper during feeding to prevent blockage.

[0015] As a further preferred embodiment of this utility model, the rotating shaft is fixedly installed with multiple splines below the propeller blade, and the lower end of the rotating shaft passes through the bushing and is inserted into the bearing in the shaft groove, and the splines are inserted into the corresponding spline holes.

[0016] Based on this, by setting the spline hole, the rotating shaft can drive the movable conical cover to rotate synchronously on the fixed conical cover when it rotates.

[0017] As a further preferred embodiment of this utility model, a limiting screw ring is also inserted on the outer side of the rotating shaft, and the limiting screw ring is also threaded to the outer side of the bushing. Based on this, the lower end of the rotating shaft is prevented from disengaging from the shaft groove and spline hole by setting the limiting screw ring.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, a fixed conical cover is installed inside the feeding hopper, and a movable conical cover is installed on the fixed conical cover. This allows the motor to simultaneously stir and mix the material in the feeding hopper via the rotating shaft and the propeller blades when material needs to be fed. At the same time, the movable conical cover is driven to rotate, thereby achieving the intermittent overlap of the first and second feeding ports. This ensures the synchronization of feeding opening, feeding closing, and material stirring and mixing, reducing the probability of blockage caused by material feeding and improving the quality of material mixing.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-5As shown, this utility model provides a novel feeding device for an antioxidant production reactor, including a feeding hopper 1. A sleeve 2 is provided in the middle of the feeding hopper 1. Multiple support plates 3 are fixedly connected to the outside of the sleeve 2 and the feeding hopper 1. A flow guide shroud 4 is fixedly installed on the multiple support plates 3. A motor 5 is fixedly installed on the flow guide shroud 4, and the motor 5 is electrically connected to an external main controller through a connecting wire. A rotating shaft 6 is fixedly installed at the output end of the motor 5. The rotating shaft 6 extends through the sleeve 2 to the lower part of the feeding hopper 1, and a propeller blade 7 is fixedly installed below the sleeve 2 on the rotating shaft 6. A first flange 8 is fixedly installed at the lower end of the feeding hopper 1. A second flange 9 is fixedly installed at the lower end of the first flange 8. A third flange 10 is fixedly installed between the first flange 8 and the second flange 9. A fixed conical cover 11 is fixedly installed inside the third flange 10, and the fixed conical cover 11 is located inside the feeding hopper 1. A movable conical cover 12 is movably installed on the fixed conical cover 11.

[0028] like Figure 2 As shown, a bearing seat 13 is provided in the middle of the sleeve 2. Multiple connecting plates 14 are fixedly connected between the outer side of the bearing seat 13 and the sleeve 2. The rotating shaft 6 is inserted into the bearing seat 13. With the help of the bearing seat 13, the rotating shaft 6 can rotate more stably.

[0029] like Figures 2-5As shown, the fixed conical cover 11 has two first discharge ports 18. A shaft groove 19 is located in the middle of the fixed conical cover 11 between the two first discharge ports 18. A connecting ring 16 is fixedly installed on the outside of the fixed conical cover 11, and the connecting ring 16 is fixedly installed inside the third flange 10. The two first discharge ports 18 in the fixed conical cover 11 allow material in the feeding hopper 1 to enter the reactor through the first discharge ports 18. The movable conical cover 12 has multiple second discharge ports 20, and the transverse contour of the second discharge ports 20 is the same as the transverse contour of the first discharge ports 18. A bushing 21 is fixedly installed in the middle of the movable conical cover 12, and a spline hole 22 is provided in the bushing 21. The movable conical cover 12 is rotatably connected to the fixed conical cover 11, and the spline hole 22 communicates with the shaft groove 19. The rotation of the rotating shaft 6 can drive the movable conical cover 12 to... The fixed conical cover 11 rotates, thereby aligning the second discharge port 20 with the first discharge port 18 to achieve material discharge. The misalignment of the first discharge port 18 and the second discharge port 20 enables automatic material discharge to stop. Simultaneously, the propeller blade 7 agitates the material in the feeding hopper 1 during material discharge to prevent blockage. The rotating shaft 6 is fixedly installed with multiple splines 15 below the propeller blade 7. The lower end of the rotating shaft 6 passes through the bushing 21 and is inserted into the bearing in the shaft groove 19. The splines 15 are inserted into the corresponding spline holes 22. The spline holes 22 enable the rotating shaft 6 to drive the movable conical cover 12 to rotate synchronously on the fixed conical cover 11 when rotating. A limiting screw ring 17 is also inserted on the outside of the rotating shaft 6 and is threaded to the outside of the bushing 21. The limiting screw ring 17 prevents the lower end of the rotating shaft 6 from detaching from the shaft groove 19 and the spline hole 22.

[0030] It should be noted that this utility model is a novel feeding device for an antioxidant production reactor. After different materials are conveyed into the feeding hopper 1 by a conveying mechanism such as a screw conveyor, the materials can be temporarily stored in the feeding hopper 1. During feeding, the motor 5 can be started by an external main controller. Then, the output end of the motor 5 drives the rotating shaft 6 to rotate, thereby causing the rotating shaft 6 to drive the outer propeller blades 7 to stir and mix the materials in the feeding hopper 1 and to convey the materials at the bottom of the feeding hopper 1 upwards, thereby preventing the materials from clogging during feeding. Simultaneously, the rotating shaft 6, through multiple splines on the outer side... 15 drives the bushing 21 to rotate, which in turn causes the bushing 21 to drive the movable conical cover 12 to rotate on the fixed conical cover 11. This causes the three second discharge ports 20 inside the movable conical cover 12 to overlap with the corresponding first discharge ports 18 after the movable conical cover 12 rotates for a certain period of time. This allows the material in the feeding hopper 1 to fall into the reactor through the overlapping first discharge ports 18 and second discharge ports 20. After the quantitative feeding is completed, the part of the movable conical cover 12 located between the two second discharge ports 20 covers the first discharge port 18, thereby closing the lower end of the feeding hopper 1 and stopping the unloading.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
