Technical Field
[0001] The utility model relates to the technical field of the feeding mechanism of a reaction kettle, in particular to a feeding mechanism applied to a reaction kettle. Background Technique
[0002] A reaction kettle, also known as a reactor or reaction tank, is a device widely used in the fields of chemistry, chemical engineering, etc. It is mainly a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized. During the operation process, the reaction kettle needs to strictly control reaction conditions such as temperature, pressure, stirring speed, etc. to ensure the safety and efficiency of the reaction of the liquid.
[0003] There are many structures inside the reaction kettle, such as a stirring mechanism, a transmission device, a shaft seal device, a feeding mechanism, etc. Among them, the feeding mechanism of the reaction kettle is a crucial part of the reaction kettle system. It is responsible for safely and accurately feeding raw materials or reactants into the reaction kettle for chemical reactions. According to different raw material properties and reaction requirements, the design and functions of the feeding mechanism will also be different. There are many types of feeding mechanisms, such as a screw extrusion feeding mechanism, a vibrating feeder, etc. There are many types of raw material forms that need to react inside the reaction kettle, such as liquids.
[0004] Currently, when the reaction kettle conducts a chemical reaction on liquid raw materials, it is usually necessary to transport a variety of liquid raw materials into the reaction kettle, then adjust various parameters according to actual requirements, and then start the stirring mechanism to mix the various liquid raw materials so that they can react and then stop the stirring mechanism to take out the reaction product.
[0005] However, when transporting liquid raw materials into the reaction kettle through the feeding mechanism, it is usually to transport the liquid raw materials into it from the top of the reaction kettle, so that it can first contact the top of other liquid raw materials, and then mix with liquid raw materials at other heights through the stirring structure. This method is likely to cause the mixing efficiency to slow down, thus affecting the reaction efficiency of the raw materials in the reaction kettle. Content of the Utility Model
[0006] Based on this, the purpose of the utility model is to provide a feeding mechanism applied to a reaction kettle to solve the technical problem that when transporting liquid raw materials into the reaction kettle through the feeding mechanism, it is usually to transport the liquid raw materials into it from the top of the reaction kettle, so that it can first contact the top of other liquid raw materials, and then mix with liquid raw materials at other heights through the stirring structure. This method is likely to cause the mixing efficiency to slow down, thus affecting the reaction efficiency of the raw materials in the reaction kettle.
[0007] To achieve the above object, the present utility model provides the following technical solutions: A feeding mechanism applied to a reaction kettle, including a barrel body, the top of the barrel body is movably connected with a top cover, a rotating shaft movably penetrates through the top cover, a driving structure is arranged on the outer surface of the rotating shaft, a first feeding port and an exhaust port are arranged on the top cover, a discharge port is arranged at the bottom of the barrel body, a first cavity is arranged inside the rotating shaft, a group of second stirring blades are fixedly connected to the outer surface of the rotating shaft, a second cavity connected to the first cavity is arranged inside the second stirring blade, a liquid outlet is arranged at one end of the second stirring blade, a connecting shaft is rotatably connected to one end of the liquid outlet, a movable plate is fixedly connected to the outer surface of the connecting shaft, a torsion spring is arranged at the connection between the connecting shaft and the liquid outlet, a guide block is fixedly connected to one side of the movable plate through a connecting plate, the guide block is arranged in a semi-circular structure, and a group of symmetrical inclined plane structures are arranged on each side of each guide block close to the liquid outlet.
[0008] By adopting the above technical solutions, the driving structure drives the rotating shaft and the second stirring blades to rotate rapidly. Thus, during the rotation of the guide block, it is resisted by the liquid raw materials in the barrel body, driving the movable plate to rotate, so that the liquid outlet of the second stirring blade is opened, enabling the liquid raw materials stored in the rotating shaft to flow into the barrel body. At the same time, the liquid raw materials discharged by the second stirring blade flow to both sides through a group of symmetrical inclined plane structures on one side of the guide block, facilitating rapid mixing and stirring with other liquid raw materials at the bottom and top of the barrel body, thereby improving the reaction efficiency of various raw materials inside the reaction kettle.

[0010] By adopting the above technical solutions, liquid raw materials are conveyed into the rotating shaft through the second feeding port for storage. After a specified amount of liquid raw materials is conveyed, gas can be conveyed into the rotating shaft through the air pipe, applying force to the liquid raw materials to push them. The liquid raw materials can push the elastic blocks, causing the elastic blocks to deform and the liquid raw materials to flow out. After all the liquid raw materials flow out of the rotating shaft, the gas conveyance can be stopped, so that the pressure on the elastic blocks gradually decreases, and they return to their original state, preventing the liquid in the barrel body from flowing back into the rotating shaft and affecting the mixing of the raw materials.
[0011] The present utility model is further configured such that a plurality of first stirring blades are fixedly connected to the outer surface of the rotating shaft, and a number of holes are arranged on the outer surface of the first stirring blades.
[0012] By adopting the above technical solutions, the liquid raw materials inside the barrel body can be better mixed and stirred. The existence of the holes increases the contact area between the stirring blades and the stirred materials, thereby improving the stirring efficiency.

[0014] By adopting the above technical solution, the motor can drive the second helical gear and the first helical gear meshing with its outer surface to rotate through the shaft, so that the rotating shaft rotates on the top cover, thereby driving the first stirring blade and the second stirring blade to rotate, which is convenient for better mixing the raw materials in the barrel body.
[0015] The present utility model is further configured such that a second feeding port is arranged at the top of the rotating shaft.
[0016] By adopting the above technical solution, the liquid raw material that needs to be mixed with other liquid raw materials can be conveyed into the rotating shaft through the second feeding port for storage.

[0018] By adopting the above technical solution, it is convenient for the liquid raw material stored in the second stirring blade and the rotating shaft to flow into the barrel body and be mixed with other raw materials.
[0019] The present utility model is further configured such that a blocking block is movably connected inside the second feeding port.
[0020] By adopting the above technical solution, the second feeding port can be blocked by the blocking block, so that the gas conveyed into the rotating shaft by the air pipe cannot be discharged through the second feeding port. Therefore, the pressure on the liquid raw material stored in the rotating shaft can be better applied.
[0021] In summary, the present utility model mainly has the following beneficial effects:
[0022] 1. By arranging a driving structure on the outer surface of the rotating shaft, the present utility model enables the driving structure to drive the rotating shaft and the second stirring blade to rotate rapidly. During the rotation of the guide block, the movable plate is driven to rotate due to the resistance of the liquid raw material in the barrel body, so that the discharge port of the second stirring blade is opened, and the liquid raw material stored in the rotating shaft can flow into the barrel body. At the same time, the liquid raw material discharged by the second stirring blade flows to both sides through a set of symmetrical inclined surface structures on one side of the guide block, which is convenient for quickly mixing and stirring with other liquid raw materials at the bottom and top of the barrel body, thereby improving the reaction efficiency of various raw materials inside the reaction kettle;

After a specified amount of liquid raw materials is transported, gas can be transported into the rotating shaft through an air pipe, so as to apply force to the liquid raw materials to push them. The liquid raw materials can push the elastic block, causing the elastic block to deform and the liquid raw materials to flow out.

Detailed Embodiment
[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.
[0030] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.
[0031] A feeding mechanism applied to a reaction kettle, as Figures 1-4As shown in the figure, it includes a barrel body 1, and a top cover 2 is connected to the top of the barrel body 1. Then, the barrel body 1 can be kept in a sealed state through the top cover 2. A first feeding port 17 and an exhaust port 22 are provided on the top cover 2. Then, a large amount of liquid raw materials can be first put into the barrel body 1 through the first feeding port 17. At the same time, the function of the exhaust port 22 is to discharge the gas generated in the barrel body 1, avoiding affecting the use of the device due to excessive gas in the barrel body 1. A discharge port is provided at the bottom of the barrel body 1. Therefore, after the reaction of various liquid raw materials in the barrel body 1 is completed, the discharge port can be opened for taking materials.
[0032] At the same time, a rotating shaft 3 penetrates through the top cover 2 movably. A driving structure is arranged on the outer surface of the rotating shaft 3. Therefore, the rotating shaft 3 can be driven to rotate through the driving structure. A second feeding port 23 is arranged at the top of the rotating shaft 3. A blocking block 15 is movably connected in the second feeding port 23. Then, other liquid raw materials can be conveyed into the rotating shaft 3 through the second feeding port 23 for storage, so as to add them into the interior of the barrel body 1 after the device is started. At the same time, after adding liquid raw materials into the rotating shaft 3, the second feeding port 23 can be blocked by the blocking block 15 to avoid affecting the use of the device.
[0033] The driving structure includes a first bevel gear 18 fixedly connected to the outer surface of the rotating shaft 3. A second bevel gear 19 meshing with the first bevel gear 18 is arranged on the outer surface of the first bevel gear 18. One end of the second bevel gear 19 is connected to the output end of a motor 20 through a shaft. The motor 20 drives the second bevel gear 19 and the first bevel gear 18 fitting on its outer surface to rotate through the shaft. Therefore, the rotating shaft 3 can be driven to rotate synchronously. The motor 20 is placed inside a soundproof box 21. The soundproof box 21 is fixedly connected to the top of the top cover 2. The position of the motor 20 is fixed through the soundproof box 21. At the same time, the soundproof box 21 can reduce the noise generated when the motor 20 operates.
[0034] Then, a first cavity 6 is arranged in the rotating shaft 3. A group of second stirring blades 5 are fixedly connected to the outer surface of the rotating shaft 3. A second cavity 24 connected to the first cavity 6 is arranged in the second stirring blades 5. Then, the liquid raw materials conveyed into the rotating shaft 3 can be stored through the first cavity 6 and the second cavity 24. A liquid outlet 7 is arranged at one end of the second stirring blades 5. And the interior of the second stirring blades 5 is all arranged as an inclined plane structure. Therefore, after the liquid outlet 7 is opened, the liquid raw materials can be discharged from the rotating shaft 3 and the interior of the second stirring blades 5 to be mixed and stirred with other liquid raw materials in the barrel body 1.
[0035] Meanwhile, a connecting shaft 8 is rotatably connected to one end of the liquid outlet 7. A movable plate 10 is fixedly connected to the outer surface of the connecting shaft 8. The movable plate 10 can be driven to rotate by the connecting shaft 8. One side of the movable plate 10 is fixedly connected to a guide block 12 through a connecting plate 11. The guide block 12 is arranged in a semi-circular structure. When the rotating shaft 3 drives the second stirring blade 5 and the guide block 12 to rotate clockwise, a set of guide blocks 12 are respectively driven by the resistance of the liquid raw material in the barrel body 1 to drive the corresponding movable plates 10 to move counterclockwise, so that the liquid outlet 7 is opened. Then the liquid raw material stored in the rotating shaft 3 can enter the inside of the barrel body 1 and be mixed and stirred with other liquid raw materials. A set of symmetrical inclined plane structures are arranged on one side of each guide block 12 close to the liquid outlet 7. Therefore, when the liquid raw material stored in the rotating shaft 3 flows out into the barrel body 1, it can flow to both ends through the action of the guide block 12, which helps to quickly mix and stir with the liquid raw materials at the bottom and top of the barrel body 1, thereby improving the reaction efficiency of various liquid raw materials in the reaction kettle. A torsion spring 9 is arranged at the connection between the connecting shaft 8 and the liquid outlet 7. Therefore, after the rotating shaft 3 stops rotating, the torsion spring 9 can drive the connecting shaft 8 and the movable plate 10 to return to their original positions, thereby synchronously driving the guide block 12 to return to its original position, which is convenient for repeated use of the device.
[0036] Furthermore, an air pipe 16 penetrates through the top of the rotating shaft 3, and elastic blocks 13 are installed on both sides inside the second stirring blade 5. After storing liquid raw materials in the rotating shaft 3 through the second feeding port 23, the driving structure can be started to rotate. At this time, an external air pump device can be connected through the air pipe 16 to convey gas into the rotating shaft 3, so as to apply pressure to the liquid raw materials stored in the rotating shaft 3 for movement. Then the liquid raw materials will push the elastic blocks 13 to deform, so that the elastic blocks 13 inside the second stirring blade 5 are in an open state. And because the rotating shaft 3 drives the second stirring blade 5 to rotate, the liquid outlet 7 is also in an open state, so that the liquid raw materials stored in the rotating shaft 3 can flow into the barrel body 1 until all of them flow out and then stop conveying gas, so that the pressure received by the elastic blocks 13 slowly disappears, and then they return to their original state to block the first stirring blade 4, avoiding the backflow of the liquid raw materials in the barrel body 1 into the rotating shaft 3, thereby affecting the mixing of the raw materials.
[0037] Meanwhile, a plurality of first stirring blades 4 are fixedly connected to the outer surface of the rotating shaft 3. The rotating shaft 3 can drive the first stirring blades 4 to rotate, so as to mix and stir various liquid raw materials in the barrel body 1. And a number of holes 14 are arranged on the outer surface of the first stirring blade 4, so that the contact area between the first stirring blade 4 and various liquid raw materials in the barrel body 1 becomes larger, thereby improving the stirring efficiency.
[0038] In this embodiment, the gas conveyed into the rotating shaft 3 will not affect the reaction of the raw materials in the reaction kettle.
[0039] Although embodiments of the present utility model have been shown and described, the specific embodiments are merely explanations of the present utility model and do not limit the utility model. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
