Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging, in particular to a multi-material feeding and mixing system for a reactor. Background Art

[0002] In some explosion-proof environments in the pharmaceutical, chemical, and new energy industries, if multiple materials need to be added to a reactor, manual or semi-automatic feeding is generally used, which requires human participation. Existing feeding devices that do not require human participation, such as an automatic feeding device for a reactor disclosed in Patent No. CN217856028U, drive different storage tanks to rotate by rotating the placement turntable, and then drive the filling pipes of the storage tanks to dock with the feed pipe of the reactor to cooperate in filling, thereby realizing the addition of different materials.

[0003] In the case where the demand for adding one material is large and the demand for adding other materials is small, this feeding method, since both the filling pipe and the storage tank need to rotate, cannot set a large and heavy storage tank on the turntable. There is a disadvantage of needing to frequently add material to the storage tank to meet the feeding requirements of the material with large demand, which leads to low feeding efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a multi-material feeding and mixing system for a reactor which does not require frequent feeding, has high feeding efficiency and good reaction effect.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A multi-material feeding and mixing system for a reactor comprises a support frame, a main material feeding device, a small material feeding device and a stirring device, wherein the stirring device is arranged in the reactor, and a feeding channel is obliquely provided on the reactor, the main material feeding device comprises a storage bin and an injection assembly, the storage bin is arranged on the support frame, the injection assembly is rotatably connected to the bottom of the storage bin via a rotary joint, the support frame is provided with a rotating seat, the injection assembly and the small material feeding device are both arranged on the rotating seat, and the injection assembly can telescopically enter and exit the feeding channel.

[0007] As a further improvement of the above technical solution: the injection assembly includes a dropper, a mounting sleeve and a telescopic injection tube, the mounting sleeve is arranged on a rotating seat, one end of the dropper is rotatably connected to the storage bin through a rotating joint, and the other end is connected to the mounting sleeve, the length of the telescopic injection tube is greater than the length of the mounting sleeve, the telescopic injection tube is slidably arranged in the mounting sleeve, the top of the telescopic injection tube is provided with a connecting part for connecting to the telescopic drive and a limiting part for limiting the telescopic position, and the middle is provided with a feeding port for communicating with the dropper.

[0008] Both the installation sleeve and the telescopic injection pipe are arranged obliquely towards the outside of the storage bin. A docking member is movably sleeved at the bottom of the installation sleeve. A first docking plate for docking and pressing with the feeding channel is provided at the bottom of the docking member. Avoidance spaces for the telescopic injection pipe to pass through are provided in the middle of both the docking member and the first docking plate.

[0009] The blanking pipe is arranged obliquely. A vibrator for assisting blanking is provided on the blanking pipe.

[0010] The multi-material feeding and mixing system of the reaction kettle further includes a rotary drive device for driving the stirring device to rotate. The rotary drive device is arranged at the top of the reaction kettle.

[0011] A first switching valve is provided at the bottom of the storage bin. The first switching valve is located above the rotary joint.

[0012] The small material feeding device includes a feeding hopper and a blanking pipe. The feeding hopper is arranged on a rotating seat. One end of the blanking pipe is connected to the bottom of the feeding hopper, and the other end is provided with a second docking plate for docking and pressing with the feeding channel.

[0013] A second switching valve is provided on the blanking pipe.

[0014] The multi-material feeding and mixing system of the reaction kettle further includes a receiving tray. The receiving tray is movably arranged on a support frame. The receiving tray is used for receiving materials after the main material feeding device finishes feeding.

The protective cover is used to cover the feeding port of the reaction kettle. The lifting drive assembly is used to drive the protective cover to lift and lower. The swinging drive assembly is used to drive the protective cover to swing.

[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] In the multi-material feeding and mixing system of the reaction kettle disclosed by the present utility model, the storage bin for storing the main material is rotatably connected to the injection component. When the injection component needs to rotate for feeding, the storage bin does not need to rotate accordingly. The relatively fixed storage bin can store more main materials, without the need for frequent feeding, improving the feeding efficiency. At the same time, only the injection component with a smaller volume and lighter weight needs to be driven to rotate, which is also convenient for the manufacturing and layout of the rotating seat. It is especially suitable for application scenarios where the demand for one material for feeding is large and the demand for other materials for feeding is small. In addition, the injection component can telescopically enter and exit the feeding channel, enabling the injection component to pass through the feeding channel and extend into the reaction kettle for feeding, avoiding material dust from floating and sticking to the top of the kettle and affecting the reaction effect.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0028] Figures 1 to 5 shows an embodiment of the multi-material feeding and mixing system of the reaction kettle of the present utility model. The multi-material feeding and mixing system of the reaction kettle in this embodiment includes a support frame 1, a main material feeding device 2, a minor material feeding device 3, and a stirring device 8. The stirring device 8 is arranged inside the reaction kettle. An inlet channel 10 is inclinedly arranged on the reaction kettle. The main material feeding device 2 includes a storage bin 21 and a filling component 22. The storage bin 21 is arranged on the support frame 1. The filling component 22 is rotatably connected to the bottom of the storage bin 21 through a rotary joint 23. A rotating base 11 is arranged on the support frame 1. Both the filling component 22 and the minor material feeding device 3 are arranged on the rotating base 11. The filling component 22 can telescopically enter and exit the inlet channel 10.

[0029] The feeding and mixing process of the multi-material feeding and mixing system of the reaction kettle is as follows: 1) Feeding the main material: The rotating base 11 drives the filling component 22 to rotate until it is docked with the inlet channel 10. After docking, the filling component 22 extends into the inlet channel 10 and the reaction kettle. The material in the storage bin 21 enters the reaction kettle through the filling component 22 and the inlet channel 10. After the main material is fed, the filling component 22 retracts; 2) Feeding the minor material: The rotating base 11 drives the minor material feeding device 3 to rotate until it is docked with the inlet channel 10. After docking, the minor material is fed into the reaction kettle through the inlet channel 10; 3) Mixing: The stirring device 8 stirs and mixes the two materials in the reaction kettle.

[0030] The multi-material feeding and mixing system of the reactor. The storage bin 21 for storing the main material is rotatably connected to the feeding component 22. When it is necessary to rotate the feeding component 22 for feeding, the storage bin 21 does not need to rotate along with it. The relatively fixed storage bin 21 can store more main materials, without the need for frequent feeding, improving the feeding efficiency. At the same time, only the smaller and lighter feeding component 22 needs to be driven to rotate, which is also convenient for the manufacture and layout of the rotating seat 11, especially suitable for application scenarios where the demand for one material feeding is large and the demand for other material feeding is small. In addition, the feeding component 22 can telescopically enter and exit the feeding channel 10, so that the feeding component 22 can pass through the feeding channel 10 and extend into the reactor for feeding, avoiding the floating and sticking of material dust on the top of the kettle and affecting the reaction effect. Further preferably, during the feeding process, the feeding component 22 can gradually rise as the height of the material inside the reactor increases, so as to avoid the contact between the feeding device and the material inside the reactor. A feeding head (not shown in the figure) is provided at the top of the storage bin 21, and a level sensor (not shown in the figure) is provided at the bottom. The level sensor is electrically connected to the feeding head and can be used to realize automatic feeding.

[0031] Further, as Figure 2 and Figure 3 shown, in this embodiment, the feeding component 22 includes a blanking pipe 221, a mounting sleeve 222, and a telescopic feeding pipe 223. The mounting sleeve 222 is arranged on the rotating seat 11. One end of the blanking pipe 221 is rotatably connected to the storage bin 21 through a rotary joint 23, and the other end is connected to the mounting sleeve 222. The length of the telescopic feeding pipe 223 is greater than the length of the mounting sleeve 222. The telescopic feeding pipe 223 is slidably arranged in the mounting sleeve 222. A connecting portion 229 for connecting with the telescopic drive and a limiting portion 230 for limiting the telescopic position are provided at the top of the telescopic feeding pipe 223, and a feeding port 224 for communicating with the blanking pipe 221 is provided in the middle. When adding the main material, the mounting sleeve 222 is docked with the feeding channel 10, and the telescopic drive unit (not shown in the figure) drives the connecting portion 229 to move, driving the telescopic feeding pipe 223 to pass through the feeding channel 10 and extend into the reactor until the limiting portion 230 abuts against the top of the mounting sleeve 222, indicating that the extension is completed. The material in the storage bin 21 reaches the feeding port 224 through the blanking pipe 221, and then falls into the reactor through the telescopic feeding pipe 223. After the feeding is completed, the telescopic drive unit drives the connecting portion 229 to move in the reverse direction, driving the telescopic feeding pipe 223 to retract and reset.

[0032] Further, as Figure 2 and Figure 3As shown, in this embodiment, both the mounting sleeve 222 and the telescopic feeding pipe 223 are arranged obliquely towards the outside of the storage bin 21. A docking member 225 is movably sleeved at the bottom of the mounting sleeve 222. A first docking plate 226 for docking and pressing tightly with the feeding channel 10 is provided at the bottom of the docking member 225. Avoidance spaces 227 for the telescopic feeding pipe 223 to pass through are provided in the middle of both the docking member 225 and the first docking plate 226. Since the feeding channel 10 is obliquely arranged, the mounting sleeve 222 and the telescopic feeding pipe 223 are obliquely arranged, which facilitates the docking with the feeding channel 10 and the telescoping of the telescopic feeding pipe 223. During docking, after the docking member 225 at the bottom of the mounting sleeve 222 is docked and pressed tightly with the feeding channel 10 through the first docking plate 226 at the bottom of the docking member 225, the telescopic feeding pipe 223 then extends into the reaction kettle, avoiding gas leakage in the reaction kettle during feeding and improving feeding safety.

[0033] Further, as Figure 1 and Figure 2 shown, in this embodiment, the blanking pipe 221 is obliquely arranged, accelerating the conveying speed of the material. Further, as Figure 2 shown, in this embodiment, a vibrator 228 for assisting blanking is provided on the blanking pipe 221, avoiding the material from adhering to the inner wall of the blanking pipe 221 and assisting the material to fall.

[0034] Further, as Figure 3 shown, the multi-material feeding and mixing system of the reaction kettle further includes a rotary driving device 9 for driving the stirring device 8 to rotate, and the rotary driving device 9 is arranged at the top of the reaction kettle.

[0035] Further, as Figure 1 shown, in this embodiment, a first switching valve 24 is provided at the bottom of the storage bin 21, and the first switching valve 24 is located above the rotary joint 23. The falling of the material in the storage bin 21 is controlled by controlling the opening and closing of the first switching valve 24. Preferably, the first switching valve 24 is a star-shaped blanking valve with good sealing performance.

[0036] Further, as Figure 4 shown, in this embodiment, the small material feeding device 3 includes a feeding hopper 31 and a blanking pipe 32. The feeding hopper 31 is arranged on the rotary seat 11. One end of the blanking pipe 32 is connected to the bottom of the feeding hopper 31, and the other end is provided with a second docking plate for docking and pressing tightly with the feeding channel 10. When adding small materials, the second docking plate (not shown in the figure, with a blanking channel for the material to pass through in the middle) is pressed tightly against the feeding channel 10 for docking, avoiding gas leakage in the reaction kettle during feeding and improving feeding safety. Then, small materials are added into the feeding hopper 31, and the small materials enter the feeding channel 10 through the blanking pipe 32 and finally enter the reaction kettle to be mixed with the main material. Further, as Figure 4 shown, in this embodiment, a second switching valve 33 is provided on the blanking pipe 32. The feeding of small materials is controlled by controlling the opening and closing of the second switching valve 33.

[0037] Furthermore, as Figure 1 shown, in this embodiment, the multi-material feeding and mixing system of the reaction kettle further includes a receiving tray 4. The receiving tray 4 is rotatably arranged on the support frame 1 and is used for receiving materials after the main material feeding device 2 finishes feeding. After the main material feeding is completed, the telescopic injection pipe 223 retracts, the docking part 225 retracts, and the receiving tray 4 rotates to be below the mounting sleeve 222 to receive materials, preventing the materials from scattering.

[0038] Furthermore, as Figure 5 shown, in this embodiment, the multi-material feeding and mixing system of the reaction kettle further includes a protective cover 5, a lifting drive assembly 6, and a swing drive assembly 7. The protective cover 5 is used to cover the feed inlet of the reaction kettle. The lifting drive assembly 6 is used to drive the protective cover 5 to lift and lower, and the swing drive assembly 7 is used to drive the protective cover 5 to swing. After the main material and the minor materials are fed, the lifting drive assembly 6 and the swing drive assembly 7 jointly drive the protective cover 5 to cover the feed channel 10, preventing the materials from leaking during the stirring process. Preferably, the minor material feeding device 3 can be lifted and lowered on the rotating seat 11, facilitating docking and pressing during feeding and covering the protective cover 5 after feeding.

[0039] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present utility model. Therefore, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
