Description

Technical Field

[0001] The utility model relates to the technical field of chemical synthesis reactors, in particular to a quantitative feeding type reactor for chemical synthesis. Background Technique

[0002] Chemical reaction kettles are mainly used for chemical reactions, and the reaction principle is mainly affected by the properties of reactants, temperature and pressure. By adding reactants into the kettle, adjusting the reaction temperature and reaction pressure, and under the action of adding catalysts or chemical substances, the chemical reaction is completed. The reaction substances absorb or release heat through heat transfer on the outer wall of the reaction kettle or through an internal jacket to complete the reaction process.

[0003] Existing quantitative feeding type reactors for chemical synthesis mostly quantify materials through weighing sensors, etc. During the chemical reaction process, raw materials and catalysts need to be added simultaneously. For the quantification of multiple materials, each component needs to be weighed separately to determine its weight. The process of multiple measurements using weighing sensors is complicated, thus reducing the batching efficiency of workers; at the same time, during the batching process of the reactor and the catalytic mixing reaction process, motors are mostly required to be configured separately for driving stirring, resulting in high costs.

[0006] Furthermore, a limiting plate slidingly connected to the blanking plate is vertically arranged on each of the inner walls of the kettle body on both sides of the blanking plate;

[0007] Explanation: The above settings can further limit the position of the blanking plate during the up and down sliding process by using the limiting plates, and at the same time can also prevent materials from falling out from both sides during the blanking process, thereby effectively improving the accuracy of the feeding amount of the quantitative feeding.

One side of the blanking baffle is rotatably connected through a strip-shaped hole on a torsion spring shaft, and a push rod corresponding to the blanking baffle one by one and used for triggering the opening of the blanking baffle is provided on the blanking port;

[0009] Explanation: The above setting can effectively trigger the blanking baffle when the material falls to the bottom by using the push rod, so as to promote the blanking of the material.

[0010] Further, a rotating shaft fixedly connected to the top of the kettle body is arranged inside the rotating cylinder. A plurality of bumps for dividing the gap into several feed bins are circumferentially spaced in the gap between the rotating shaft and the rotating cylinder. One end of the bump is clamped with the rotating shaft, and the other end is hermetically and rotatably connected to the rotating cylinder; a blanking hole corresponding to the structure of the feed bin is arranged at the bottom of the rotating cylinder;

[0011] Explanation: The above setting can add the catalyst synchronously in the rotating cylinder, and can effectively realize the purpose of adding raw materials in the blanking plate, adding the catalyst in the feed bin and realizing the quantitative ratio addition of the catalyst and the raw materials by adjusting the distance of the bumps on the rotating shaft, adapting to feed bins of different capacities, so as to improve the adaptability of the equipment and further improve the efficiency of the chemical synthesis reaction.

[0012] Furthermore, a plurality of first magnets arranged obliquely at equal intervals are provided on the inner wall of the circular hole, and a second magnet repelling the first magnet is provided on the rotating cylinder for making the rotating cylinder have a driving force in the same direction.

[0013] Explanation: The design of the repelling magnets can ensure that the rotating cylinder rotates in the same clockwise rotation direction, so as to improve the blanking efficiency of the blanking plate and further improve the reaction rate.

[0014] The beneficial effects of the present utility model are:

Specific Embodiments

[0025] The present utility model will be further described in detail below in conjunction with specific embodiments to better reflect the advantages of the present utility model.

[0026] Embodiment 1: A quantitative feeding type reaction kettle for chemical synthesis, as Figure 1 , Figure 2As shown in the figure, it includes a kettle body 1. Inside the kettle body 1, there is a partition 11. The partition 11 divides the kettle body 1 into an upper and a lower part, namely a quantitative feeding bin 2 and a reaction bin 3. At the center of the partition 11, there is a round hole 12. Inside the quantitative feeding bin 2, there is a rotating cylinder 21 whose lower end is rotatably connected to the round hole 12. Inside the reaction bin 3, there is a stirring rod 31 whose upper end is fixedly connected to the bottom of the rotating cylinder 21. The stirring rod 31 is provided with a heating rod 32. Inside the quantitative feeding bin 2, there is a blanking plate 22 which is connected to the inner wall of the kettle body 1 in a vertically limited sliding manner. And on the partition 11, directly below the blanking plate 22, there is a blanking port 221 corresponding to the blanking plate 22. On the side wall of the rotating cylinder 21, there are wave grooves 211. On the blanking plate 22, there are sliders which are slidably connected to the wave grooves 211 to make the rotating cylinder 21 rotate and discharge materials by the up and down movement of the blanking plate 22. The wave groove 211 is a bent structure with wave crests and wave troughs.

[0027] As Figure 2 , Figure 3 As shown in the figure, on the blanking plate 22, there are 6 blanking baffles 222. One side of the blanking baffle 222 is rotatably connected to a strip-shaped hole on the blanking plate 22 through a torsion spring shaft 223. And on the blanking port 221, there are ejector rods 224 corresponding to the blanking baffles 222 one by one and used to trigger the opening of the blanking baffles 222.

[0028] Among them, the bottom of the rotating cylinder 21 in this embodiment adopts a mechanism that can discharge materials by rotating and opening, specifically, it can be the structure of a commercially available rotating-opening aromatherapy box.

[0029] The working principle of this embodiment is as follows: Put the raw materials into the blanking plate 22, and add the catalyst into the rotating cylinder 21. As the raw materials are added, the blanking plate 25 moves downward along the sliding groove with a wave-shaped structure. After reaching the bottom, the ejector rod triggers and drives the blanking baffle 222 to rotate, so that the raw materials fall into the reaction shell 3 along the blanking port 221. The downward movement of the blanking plate 22 drives the rotating cylinder 21 to rotate to realize the feeding of the catalyst. As the blanking plate 22 rotates, it can drive the rotation of the stirring rod 31 in the reaction shell 3, driving the heating rod 32 to mix and catalyze the materials. After the blanking is completed, it returns to the highest position under the action of the spring. The setting of the spring can make the blanking plate 22 return to the initial state after the materials are discharged, and thus can realize the continuous driving of the rotation of the rotating cylinder 21. For each addition of a portion of raw materials, a corresponding amount of catalyst is added once to achieve the quantitative ratio of the raw materials and the catalyst.

[0030] Embodiment 2: Different from Embodiment 1, as Figure 4 shown in the figure, on the inner walls of the kettle body 1 on both sides of the blanking plate 22, there is a vertical limiting plate 23 each which is slidably connected to the blanking plate 22.

[0031] The working principle of this embodiment is basically the same as that of Embodiment 1, except that: during the movement of the blanking plate 22, the limiting plate 23 is used for limiting, so that it is not easy to shift during the feeding process, and it can ensure that a sealed structure can be formed between the blanking plate 22 and the limiting plate 23, which is convenient for the raw materials to fall better.

[0032] Embodiment 3: Different from Embodiment 2, as Figure 5 , Figure 6 shown, a rotating shaft 24 fixedly connected to the top of the kettle body 1 is arranged inside the rotating cylinder 21. Nine bumps 241 for separating the gap into nine feeding bins 242 are circumferentially arranged at intervals in the gap between the rotating shaft 24 and the rotating cylinder 21. One end of the bump 241 is clamped with the rotating shaft 24, and the other end is hermetically and rotatably connected to the rotating cylinder 21; a blanking hole 212 corresponding to the structure of the feeding bin 242 is arranged at the bottom of the rotating cylinder 21;

[0033] The working principle of this embodiment is basically the same as that of Embodiment 1, except that: during the downward pressing of the blanking plate 22, the rotating cylinder 21 is driven clockwise, so that the position of the blanking hole 212 at the bottom of the rotating cylinder 21 changes, so that the catalyst inside the rotating cylinder 21 quickly falls. The clamping position of the bump 231 and the rotating shaft 23 is adjustable, so as to realize the quantitative addition of raw materials and catalysts in different proportions.

[0034] Embodiment 4: Different from Embodiment 3, as Figure 7 shown, five first magnetic blocks 121 inclined at 30° are equidistantly arranged on the inner wall of the round hole 12, and a second magnetic block 122 repelling the first magnetic block 121 is arranged on the rotating cylinder 21 for providing a driving force for the rotating cylinder 21 to have a rotating tendency; it should be noted that: the first magnetic block 121 and the second magnetic block 122 are arranged up and down to prevent the first magnetic block 121 and the second magnetic block 122 from colliding and causing the situation of unable to rotate.

[0035] The working principle of this embodiment is basically the same as that of Embodiment 3, except that: by using the acting force between the mutually repulsive first magnetic block 121 and second magnetic block 122, a driving force for the rotating cylinder 21 to rotate clockwise can be given, ensuring that the rotation of the rotating cylinder 21 is more effective, thereby ensuring the accuracy of quantitative addition and further improving the reaction efficiency.

[0036] Embodiment 5: Different from Embodiment 4, the first magnetic block 121 and the second magnetic block 122 are respectively embedded on the surfaces of the corresponding round hole 12 and the rotating cylinder 21, effectively avoiding the collision between the first magnetic block 121 and the second magnetic block 122.
