Description

Technical Field

[0001] The utility model relates to the technical field of material stirring, in particular to an antioxidant feeding device. Background Art

[0002] Antioxidants are compounds that prevent or slow oxidation and are widely used in food, cosmetics, pharmaceuticals, and industrial products. Stirred tanks play a crucial role in the preparation of antioxidants. They not only provide the necessary container for the reaction but also ensure thorough mixing of the reactants and uniform reaction through stirring.

[0003] After searching, the patent with authorization announcement number CN214915960U discloses an enameled reactor with a preheating function. A material preheating device is set at the feed port of the reactor body. Although it can achieve preheating of the raw materials, since it uses a heating chamber of fixed volume, during the heating process, regardless of the amount of raw materials, the entire heating space needs to be heated, resulting in a large amount of heat energy being wasted in unnecessary space. There is an urgent need for a feeding device that can more effectively improve the utilization rate of heat energy. Utility Model Content

[0004] In order to solve the problem that the material preheating device on the existing kettle body is prone to heat energy waste, the utility model provides an antioxidant feeding device. By arranging a movable filling block in the material preheating device, the size of the heating chamber in the material preheating device can be adjusted according to the amount of material, which is convenient for concentrating heat energy to preheat the material, thereby improving the heat energy utilization rate.

[0005] The utility model provides an antioxidant feeding device, comprising a kettle body, a feed port welded above the kettle body, the feed port connected to a material preheating device, a heating device welded to the bottom of the kettle body, the material preheating device and the heating device being connected via a pipeline, the material preheating device comprising a feed shell, the feed shell having a cavity inside that can accommodate material, a filling block slidably arranged in the cavity, the filling block dividing the cavity into a heating chamber and an adjustment chamber, the upper end of the pipeline being connected to the heating chamber of the feed shell, and the lower end of the pipeline being connected to the heating device. By arranging a slidable filling block in the feed shell, the size of the heating chamber can be adjusted, facilitating centralized heating of the material according to the material quantity, thereby reducing heat energy waste.

[0006] Furthermore, a driving member is provided outside the feed shell, the driving member is provided on a side of the feed shell close to the adjustment cavity, and an output end of the driving member is fixedly connected to the filling block. The filling block is driven by the driving member outside the feed shell to slide and adjust in the feed shell.

[0007] Furthermore, the driving member is an electric push rod having a fixed end and a telescopic end. The fixed end is fixedly arranged outside the feed shell, and the telescopic end extends into the adjustment cavity and is connected to the filling block. The electric push rod is used to adjust the filling block, which has a simple structure and convenient operation.

[0008] Furthermore, a material guide slope is formed on one side of the filling block near the heating chamber, and a feed pipe connected to the heating chamber is provided on the feed shell. The feed pipe is also equipped with a valve. The material added from the feed pipe is dispersed by the material guide slope and falls into the heating chamber, so that the material is heated more evenly.

[0009] Furthermore, the heating device is an additional shell welded and fixed to the bottom of the kettle body, with a steam inlet at one end of the additional shell away from the feed shell and a steam outlet at the other end, and a pipe connected to the steam outlet to heat the kettle body by introducing hot steam.

[0010] Furthermore, the heating device is an additional shell welded and fixed to the bottom of the kettle body, a heating wire is arranged in the additional shell, and a pipe is connected to the side of the additional shell close to the feed shell. The kettle body is heated by the heating wire.

[0011] Furthermore, a sealing ring is provided on the contact surface where the filling block slides against the inner wall of the feed housing. An air cavity is defined within the sealing ring, which is connected to an air pump located outside the feed housing via an air duct. The air pump inflates the air cavity within the sealing ring via the air duct. The expansion of the sealing ring seals the gap between the filling block and the interior of the feed housing, improving sealing performance. Before adjusting the filling block, the air in the cavity must be pumped out using the air pump to ensure smooth sliding.

[0012] Furthermore, a groove is formed on the outer periphery of the filling block, the sealing ring is placed in the groove, and a corresponding tube hole is formed on the filling block for the air guide tube to extend into. The groove limits the sealing ring to reduce the phenomenon of the sealing ring moving outside the filling block during the sliding process of the filling block.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In order to adjust the volume of the heating chamber and improve the utilization rate of thermal energy, an antioxidant feeding device is designed, such as Figure 1 As shown, it includes a kettle body 1, a feed port is welded on the top of the kettle body 1, the feed port is connected to a material preheating device, a heating device is welded on the bottom of the kettle body 1, and the material preheating device and the heating device are connected through a pipe 2. A discharge port is provided at the bottom of the kettle body 1, and the material enters the kettle body 1 from the upper feed port for stirring, and then is discharged from the discharge port. A stirring rod and stirring blades are provided inside the kettle body 1, and a motor and a reducer for driving the stirring rod to rotate are provided on the top of the kettle body, so that the motor speed can be reduced to the speed required for stirring, thereby increasing the stability of stirring. This part of the structure is a mature existing technology, which is disclosed in detail in the patent with publication number CN212975090U and will not be described in detail here.

[0023] like Figure 2As shown, the material preheating device specifically includes a feed housing 3, which contains a cavity capable of accommodating the material. A filler block 4 is slidably disposed within the cavity, dividing the cavity into a heating chamber 5 and a regulating chamber 6. The upper end of a pipe 2 communicates with the heating chamber 5 of the feed housing 3, while the lower end of the pipe 2 communicates with the heating device. Excess steam not used in the heating device is discharged through the pipe 2 into the heating chamber 5 of the feed housing 3 to preheat the material, avoiding heat energy waste and reducing steam costs.

[0024] The space of the heating chamber 5 can be adjusted by the filling block 4. After the material enters the feed shell 3, the heating chamber 5 can be adjusted according to the volume of the material, so that the volume of the heating chamber 5 is slightly larger than the volume of the material inside the feed shell 3. The material in the heating chamber 5 is then heated by the heating device, thus completing the preheating treatment of the material. After the treatment is completed, the valve on the pipeline connected to the kettle body 1 is opened, and the preheated material can be transported to the kettle body 1 through the pipeline for stirring. The material heated and stirred by the kettle body 1 is discharged from the discharge port at the bottom of the kettle body 1, completing the processing. In the process of preheating the material, by adjusting the volume of the heating chamber, the space required for heating can be reduced, so that the heat energy can be concentrated to heat the material, thereby improving the utilization rate of the heat energy and reducing the waste of the heat energy.

[0025] like Figure 3 As shown, in order to adjust the filling block 4, a driving member is provided on the outside of the feed shell 3. The driving member is arranged on the side of the feed shell 3 close to the adjustment chamber 6, and the output end of the driving member is fixedly connected to the filling block 4. The filling block 4 is slid in the cavity of the feed shell 3 by the external driving member to adjust the space of the heating chamber 5 to adapt to the preheating of different amounts of materials. Preferably, the driving member is an electric push rod 7, which has a fixed end and a telescopic end. The fixed end is fixedly arranged on the outside of the feed shell 3, and the telescopic end extends into the adjustment chamber 6 and is connected to the filling block 4. The electric push rod 7 has a simple structure, is easy to operate, and has good driving stability.

[0026] In order to heat the material in the feed shell 3 more evenly, a material guide slope 8 is formed on the side of the filling block 4 close to the heating chamber 5. The feed shell 3 is provided with a feed pipe 9 connected to the heating chamber 5, and the feed pipe 9 is also provided with a valve 10. When the material is fed into the feed pipe 9, it will first fall onto the material guide slope 8 and then slide along the material guide slope 8. In the process of sliding on the material guide slope 8, the material will gradually spread from the point shape at the time of feeding to the surface shape, making the material on the upper side of the material guide slope 8 more dispersed, so that the material is heated more evenly and enters the kettle body 1.

[0027] The heating device can be an additional shell 11 welded to the bottom of the kettle body 1. A steam inlet 12 is provided at one end of the additional shell 11, away from the feed shell 3, and a steam outlet 13 is provided at the other end. The pipe 2 is connected to the steam outlet 13. The additional shell 11 can heat the material inside the kettle body 1. A drain port is also welded to the bottom of the additional shell 11 to drain condensed water from the steam inside the additional shell 11. A steam outlet 13 is welded to the upper left end of the additional shell 11, allowing excess steam from the additional shell 1 to be discharged through the pipe 2 into the heating chamber 5 of the feed shell 3 to preheat the material.

[0028] The heating device can also be an additional shell 11 welded to the bottom of the kettle body 1, with a heating wire inside the additional shell 11, and the pipe 2 is connected to the side of the additional shell 11 close to the feed shell 3. The interior of the feed shell 3 is independently temperature-controlled by heating with the heating wire.

[0029] like Figure 4 As shown, in order to seal the heating chamber 5, a sealing ring 14 is provided on the contact surface where the filling block 4 slides with the inner wall of the feed shell 3. An air cavity 141 is provided inside the sealing ring 14. The air cavity 141 is connected to an air pump 16 provided outside the feed shell 3 through an air guide tube 15. When the filling block 4 moves, the air pump 16 is started to reduce the air pressure inside the sealing ring 14, so that the sealing ring 14 shrinks into the groove 17, and a gap is generated between the sealing ring 14 and the feed shell 3, so that the filling block 4 can slide smoothly and reduce the wear of the sealing ring 14 caused by the movement of the filling block 4. After the filling block 4 has finished moving, the air pump 16 is started to inflate the sealing ring 14, so that the volume of the sealing ring 14 can be expanded, filling the gap between the filling block 4 and the feed shell 3 to ensure sealing.

[0030] To prevent the sealing ring 14 from shifting during the adjustment of the filling block 4, a groove 17 is formed on the outer periphery of the filling block 4. The sealing ring 14 is positioned within the groove 17. A corresponding hole 18 is formed on the filling block 4 for the air guide tube 15 to extend into. The groove 17 limits the position of the sealing ring 14, thereby reducing the possibility of the sealing ring 14 shifting outside the filling block 4 when the filling block 4 is moved.

[0031] The above description is only illustrative and not restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the appended claims, but all of them will fall within the scope of protection of the present invention.
