[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] It can be understood that the terms "first", "second", etc. used in the present application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0035] As Figure 1 、 Figure 2 and Figure 10 shown, in one embodiment, a rapid quantitative feeding device for a reactor is proposed, and the device includes:

[0036] Main cylinder 1: It includes an installation cylinder body 101 provided on the main cylinder 1. Two compression springs 102 are fixedly installed inside the installation cylinder body 101. The other ends of the compression springs 102 are connected to a movable inner cylinder 103 for storing liquid. A feed pipe 104 for liquid inlet and a discharge pipe 105 for liquid outlet are fixedly installed on the surface of the movable inner cylinder 103. The feed pipe 104 and the discharge pipe 105 are respectively slidably connected to two U-shaped grooves formed on the surface of the installation cylinder body 101. A connection shell 106 for protection is also fixedly installed on the surface of the installation cylinder body 101;

[0037] Storage mechanism 2: It includes four fixed half cylinders 201 with different inner diameters and four movable half cylinders 203 with different inner diameters that are installed inside the installation cylinder body 101 and can form a complete cylinder. A movable piston 202 that cooperates with it is slidably connected to the inner wall of each fixed half cylinder 201;

[0038] Feeding mechanism 3: It is used to put particles into the complete cylinder formed by the fixed half cylinder 201 and the movable piston 202;

[0039] Rotating mechanism 4: It is used to drive the solid particles in the storage mechanism 2 to be mixed and fed;

[0040] Centrifugal mechanism 6: It is used to open the particle feeding channel through the centrifugal force generated by the drive of the drive mechanism 8;

[0041] Gravity mechanism 7: It is used to adjust the feeding amount of solid particles in the storage mechanism 2 by the action of gravity.

[0042] In the actual application of the embodiment of the present invention, when a liquid-solid particle mixing reaction is carried out, as Figure 2 shown, at this time, liquid is poured into the movable inner cylinder 103 through the feed pipe 104, and the valve on the discharge pipe 105 is closed. At this time, as the mass of the liquid in the movable inner cylinder 103 increases, the movable inner cylinder 103 vertically compresses the compression spring 102 downward, and at the same time drives the gravity mechanism 7 to move downward, as Figure 10 shown, from Figure 10When viewed from the front direction, at this time, the moving piston 202 is driven by the gravity mechanism 7 to move obliquely to the lower left. At this time, the solid particles enter between the fixed half cylinder 201 and the moving half cylinder 203 through the feeding mechanism 3. It should be noted here that since the inner diameters of the four fixed half cylinders 201 and the moving half cylinder 203 are different, the amount of solid particles added can be changed according to the volume of the cavity formed by the fixed half cylinder 201 and the moving half cylinder 203, so as to meet the required ratio of the reaction. When the liquid stops pouring, at this time, the moving piston 202 stops moving, achieving the purpose of automatically adjusting the ratio of solid particles. At the same time, the rotating mechanism 4 starts to move. The operation of the rotating mechanism 4 drives the fixed half cylinder 201 and the moving half cylinder 203 to revolve, making the outlet of the feeding mechanism 3 misaligned with the fixed half cylinder 201 and the moving half cylinder 203. At this time, the outlet of the feeding mechanism 3 is blocked by the rotating mechanism 4, and as the rotating mechanism 4 continues to rotate, it drives the moving half cylinder 203 to separate from the fixed half cylinder 201. Due to the inclined setting of the fixed half cylinder 201, at this time, as the moving half cylinder 203 separates from the fixed half cylinder 201, the solid particles in the cavity of the fixed half cylinder 201 and the moving half cylinder 203 fall. At the same time, due to the inclined guiding effect of the moving half cylinder 203, the solid particles in the cavities of the four fixed half cylinders 201 and the moving half cylinder 203 converge towards the central axis position of the moving inner cylinder 103, thus achieving the purpose of automatically mixing the solid particles. When the mixed solid particles fall on the centrifugal mechanism 6, at this time, under the driving action of the driving mechanism 8, the centrifugal mechanism 6 is driven to rotate. When a certain rotational speed is reached, under the action of centrifugal force, the centrifugal mechanism 6 opens the outlet, and the solid particles fall on the centrifugal mechanism 6 by gravity and diverge. Due to the rotation of the centrifugal mechanism 6 and the shape characteristics of the centrifugal mechanism 6, the solid particles are dispersed into the liquid after hitting the centrifugal mechanism 6. At the same time, due to the agitation of the driving mechanism 8 on the liquid, the solid particles are in full contact with the liquid, thus avoiding the abnormality of the solid particles sinking to the bottom and improving the reaction efficiency between the solid and the liquid.

[0043] As Figure 1 and Figure 5 shown, as a preferred embodiment of the present invention, the feeding mechanism 3 includes a feeding seat 301 fixedly connected to the connecting shell 106, and four feeding ports 302 are fixedly installed on the surface of the feeding seat 301.

[0044] In the actual application of the embodiment of the present invention, as Figure 1 and Figure 5 shown, when the proportional feeding of solid particles is carried out, the corresponding solid particles fall through the feeding ports 302 to the positions of the fixed half cylinder 201 and the moving half cylinder 203 with corresponding diameters, and are automatically proportioned according to the liquid mass during the subsequent movement, thus achieving the function of a stable ratio.

[0045] As Figure 5, Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown in Figure 7 , Figure 8 , Figure 9 and Figure 10 , as another preferred embodiment of the present invention, the rotating mechanism 4 includes a rotating motor 401 fixedly installed on the blanking seat 301. The output end of the rotating motor 401 penetrates through the blanking seat 301 and is rotatably connected to the blanking seat 301. A driving gear 402 is fixedly installed at the output end of the rotating motor 401. The driving gear 402 meshes with a rotating gear ring 403. The rotating gear ring 403 is fixedly installed on a conical rotating cylinder 404. The surface of the conical rotating cylinder 404 is fixedly connected to the fixed half cylinder 201. The conical rotating cylinder 404 is rotatably connected to the blanking seat 301. A connecting block 405 is fixedly installed on the surface of the movable half cylinder 203. A ball head column 406 is fixedly installed on the surface of the connecting block 405. Two guide rods 407 and two tension springs 408 are also fixedly installed on the surface of the connecting block 405. Each guide rod 407 is slidably connected to a circular hole groove formed on the conical rotating cylinder 404. The other end of the tension spring 408 is connected to the surface of the conical rotating cylinder 404. A fixed conical cylinder 409 is fixedly installed on the inner wall of the installation cylinder body 101. An inner diameter chute 410, a wave chute 411 and an outer diameter chute 412 that are matched with the ball head column 406 and connected in sequence are formed inside the fixed conical cylinder 409. The track radius of the outer diameter chute 412 is greater than the track radius of the inner diameter chute 410.

[0046] In the actual application of the embodiment of the present invention, when the movement of the moving piston 202 is completed after the liquid is poured, at this time, the solid particles are located between the fixed half cylinder 201 and the movable half cylinder 203. As shown in Figure 7 , the rotating motor 401 starts to move. The operation of the rotating motor 401 drives the rotating gear ring 403 to rotate through the gear and gear ring transmission, and then drives the conical rotating cylinder 404 to rotate. The rotation of the conical rotating cylinder 404 drives the fixed half cylinder 201 and the movable half cylinder 203 to rotate synchronously. At this time, the fixed half cylinder 201 and the movable half cylinder 203 are misaligned with the blanking port 302 after blanking, and the discharge end of the blanking port 302 is blocked by the conical rotating cylinder 404. As shown in Figure 9 , at this time, as the conical rotating cylinder 404 rotates, it drives the ball head column 406 to move along the track of the inner diameter chute 410. When the ball head column 406 moves to the wave chute 411, the track action of the wave chute 411 drives the movable half cylinder 203 to separate from the fixed half cylinder 201. When the ball head column 406 moves to the outer diameter chute 412, at this time, the distance between the fixed half cylinder 201 and the movable half cylinder 203 is the largest. As shown in Figure 10 , the solid particles located between the fixed half cylinder 201 and the movable half cylinder 203 fall along the inside of the movable half cylinder 203 under the action of gravity. As shown in Figure 5 , the falling solid particles are mixed in the air, so as to achieve the function of automatically blanking and mixing the solid particles.​​​​​​​​

[0047] As Figure 7 shown, as another preferred embodiment of the present invention, the device further includes a vibration mechanism 5. The vibration mechanism 5 includes a rotating flap 501 installed on the driving mechanism 8, and also includes a plurality of vibration springs 502 installed on the conical rotating cylinder 404. The other end of each vibration spring 502 is fixedly installed with a swing ball 503 that cooperates with the rotating flap 501.

[0048] In the actual application of the embodiment of the present invention, when the feeding of solid particles onto the centrifugal mechanism 6 is completed, at this time, the driving mechanism 8 starts to move. The operation of the driving mechanism 8 drives the rotating flap 501 to rotate. As Figure 7 shown, the rotation of the rotating flap 501 continuously strikes the swing ball 503, causing the swing ball 503 to continuously generate vibrations through the elasticity of the vibration spring 502. Then, the vibrations are transmitted to the fixed half cylinder 201 and the moving half cylinder 203, enabling the solid particles on the fixed half cylinder 201 and the moving half cylinder 203 to be fully fed.

[0049] As Figure 4 and Figure 6 shown, as another preferred embodiment of the present invention, the centrifugal mechanism 6 includes a feeding cone bin 601 fixedly installed on the surface of the fixed conical cylinder 409, and also includes a conical block 602 installed on the driving mechanism 8. Two connecting plates 603 are fixedly installed on the surface of the conical block 602. One end of each connecting plate 603 away from the conical block 602 is fixed on the surface of the centrifugal plate 604. The centrifugal plate 604 is rotationally connected to the feeding cone bin 601. Two semi-circular closing blocks 606 are slidably installed on the surface of the centrifugal plate 604, and each semi-circular closing block 606 is connected to the centrifugal plate 604 through a centrifugal spring 605. The diameter of the cooperation of the two semi-circular closing blocks 606 is larger than the outlet diameter of the feeding cone bin 601. The moving inner cylinder 103 is slidably connected to the feeding cone bin 601.

[0050] In the actual application of the embodiment of the present invention, when the driving mechanism 8 starts to operate, as Figure 4 and Figure 6 shown, at this time, the driving mechanism 8 drives the conical block 602 to rotate, and then drives the semi-circular closing blocks 606 to rotate through the connecting plates 603 and the centrifugal plate 604. As the centrifugal force of the driving mechanism 8 becomes larger and larger, at this time, the two semi-circular closing blocks 606 are driven to compress the centrifugal springs 605 under the action of the centrifugal force, thereby opening the outlet of the feeding cone bin 601, enabling the mixed solid particles to fall from the feeding cone bin 601. At the same time, due to the rotation of the conical block 602, the falling solid particles are dispersed by the impact with the conical block 602 and the acting force of the rotational force of the conical block 602, so that the solid particles are fully contacted and reacted with the liquid, avoiding the phenomenon of solid particles sinking to the bottom.

[0051] As Figure 2 and Figure 3 shown, as another preferred embodiment of the present invention, the gravity mechanism 7 includes two linkage blocks 703 fixedly installed on the moving inner cylinder 103. The surfaces of the two linkage blocks 703 are connected to both ends of the cross connecting rod 702. A moving cone block 701 is fixedly installed on the surface of the cross connecting rod 702. The moving cone block 701 is in contact with one end of the moving piston 202. A linear groove for the movement of the cross connecting rod 702 is provided on the feeding cone bin 601.

[0052] In the actual application of the embodiment of the present invention, when liquid is poured into the moving inner cylinder 103, as Figure 2 and Figure 3 shown, at this time, the moving inner cylinder 103 moves downward, driving the moving cone block 701 to move downward through the linkage block 703 and the cross connecting rod 702. At this time, due to the conical structure of the moving cone block 701, when the moving cone block 701 descends, it drives the moving piston 202 to move obliquely downward along the fixed half cylinder 201, so as to achieve the purpose of automatically adding solid particles between the fixed half cylinder 201 and the moving half cylinder 203.

[0053] As Figure 3 and Figure 5 shown, as another preferred embodiment of the present invention, the driving mechanism 8 includes a driving motor 801 fixedly installed on the feeding seat 301. The output end of the driving motor 801 penetrates through the feeding seat 301 and is rotatably connected to the feeding seat 301. A rotating shaft 802 is fixedly installed at the output end of the driving motor 801. A rotating flap 501 is coaxially fixedly installed on the surface of the rotating shaft 802. The surface of the rotating shaft 802 is rotatably connected to the moving cone block 701. A conical block 602 is also coaxially fixedly installed on the surface of the rotating shaft 802. A plurality of stirring plates 803 for stirring are fixedly installed on the surface of the rotating shaft 802.

[0054] In the actual application of the embodiment of the present invention, when the mixing of solid particles is completed, as Figure 3 shown, at this time, the driving motor 801 starts to operate. The operation of the driving motor 801 drives the centrifugal mechanism 6 to move through the rotating shaft 802, so as to complete the automatic feeding of the mixed solid particles. As Figure 5 shown, at the same time, the rotation of the rotating shaft 802 stirs the liquid through the stirring plate 803, so that the dispersed solid particles are stirred together with the liquid after contacting the liquid, avoiding the problem of solid particle sedimentation in the liquid and improving the reaction efficiency.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0056] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
