Description

Technical Field

[0001] This utility model relates to the field of powder feeding technology, specifically to an automated powder feeding device. Background Technology

[0002] Powder is a dry agent obtained by mixing and pulverizing the active ingredient, a large amount of filler, and appropriate stabilizers. Its performance requirements mainly include fineness, uniformity, stability, and powder release. In the production and processing of powders, it is necessary to add powder to the production reactor. To improve the efficiency of feeding, a dedicated powder feeding device is often used to feed the powder into the tank. This device often includes a vacuum cleaner, with the outlet of the vacuum cleaner extending into the inlet of the reactor. It also includes a storage device. The powder is put into the storage device, and the vacuum cleaner sucks the powder from the storage device into the reactor through the suction port, thus completing the powder feeding process. The existing patent authorization announcement number CN 219091979 U discloses a powder feeding device, including a feeding box, a vacuum cleaner, and a mounting frame. The vacuum cleaner pumps the material in the feeding box into the reaction vessel through a pipe. A side plate is provided on one side of the feeding box, and an installation groove is opened inside the side plate. Through the provided driving component and supporting flipping component, the packaging bag containing the powder material can be lifted to a certain height and flipped to complete the feeding of the material. When the above-mentioned patent is used, after the powder is put into the feeding box, the clumps in the powder cannot be effectively broken up and dispersed, which is not conducive to subsequent conveying and processing. In addition, the opening of the feeding box generates a lot of dust, which affects the working environment. Summary of the Invention

[0003] The purpose of this utility model is to provide an automated powder feeding device to solve the problems mentioned in the background art, such as the inability to effectively break up and disperse the clumps in the powder after it is fed from the feeding box, which is not conducive to subsequent conveying and processing, and the large amount of dust generated at the opening of the feeding box, which affects the working environment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automated powder feeding device, comprising a storage tank, a feeding hopper fixedly connected to the top of the storage tank, a dispersing component disposed inside the storage tank, a dust collection component fixedly installed on the top of the storage tank behind the feeding hopper, and a discharge pipe fixedly connected to the bottom of the storage tank; the dispersing component includes a stirring motor and multiple lugs, the multiple lugs being fixedly connected in a ring at equal intervals above the inner wall of the storage tank, multiple sliding rods being slidably connected inside each of the multiple lugs, a mesh plate fixedly connected to the top of each of the multiple sliding rods above the multiple lugs, and a support spring movably sleeved on the outside of each of the multiple sliding rods between the mesh plate and the lugs, with protrusions arranged in a ring at equal intervals on the top edge of the mesh plate, a rotating shaft fixedly installed at the bottom of the output shaft of the stirring motor inside the storage tank, the rotating shaft penetrating the mesh plate, a stirring rod fixedly connected to the outer wall of the rotating shaft above the mesh plate, and a ball bearing adapted to the protrusions fixedly connected to the bottom of the stirring rod.

[0005] Preferably, the protrusion is arranged in an arc shape, and the ball is located at the bottom of one end of the stirring rod away from the rotating shaft and directly above the protrusion.

[0006] Preferably, the mesh plate has a circular hole inside that corresponds to the rotating shaft, and the rotating shaft is slidably connected inside the circular hole.

[0007] Preferably, a second stirring rod is fixedly connected to the outer wall of the rotating shaft and is arranged longitudinally and equidistantly below the mesh plate.

[0008] Preferably, the dust collection assembly includes a closed box with a right-side opening fixedly installed on the top of the storage tank and an air extractor. The air extractor is connected to the closed box. A dust collection hood is fixedly installed on the top of the dispersion assembly near the closed box. A conveying pipe is fixedly connected between the dust collection hood and the closed box. A collection frame is movably engaged inside the closed box. A filter screen is provided at the bottom of the collection frame. A cover plate is fixedly installed on the open side of the closed box.

[0009] Preferably, the filter is made of HEPA material and is clipped into the bottom of the collection frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. When the stirring motor drives the rotating shaft to rotate, it can drive the stirring rod to rotate. The rapid rotation of the stirring rod will break up the clumps of powder. At the same time, the two stirring rods will drive the ball bearings to rotate during the rotation. The ball bearings on both sides contact the protrusions, causing the screen plate to press down and drive the bottom slide rod to slide down along the lug, and squeeze the support spring. After the ball bearings leave the protrusions, the support spring pushes the screen plate to return to its original position, thereby enabling the screen plate to achieve efficient shaking and quickly shake off the powder in the mesh, ensuring that the powder is broken up. 2. The exhaust fan draws dust into the conveying pipe through the dust hood and sends it into the enclosed box. The filter in the collection frame inside the enclosed box can filter the dust. After the air enters the lower part of the enclosed box, it is discharged by the exhaust fan, which can effectively suppress dust and improve the working environment. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: an automated powder feeding device, including a storage tank 1, a feeding hopper 3 fixedly connected to the top of the storage tank 1, a dispersing component 4 disposed inside the storage tank 1, a dust collection component 5 fixedly installed on the top of the storage tank 1 behind the feeding hopper 3, and a discharge pipe 6 fixedly connected to the bottom of the storage tank 1; the dispersing component 4 includes a stirring motor 42 and multiple lugs 41, the multiple lugs 41 being fixedly connected in a ring at equal intervals above the inner wall of the storage tank 1, multiple sliding rods 43 being slidably connected inside each of the multiple lugs 41, a mesh plate 44 fixedly connected to the top of each of the multiple sliding rods 43 above the multiple lugs 41, and a support spring 45 movably sleeved on the outside of each of the multiple sliding rods 43 between the mesh plate 44 and the lugs 41, the top edge of the mesh plate 44 being provided with protrusions 46 in a ring at equal intervals, and a discharge pipe 6 fixedly installed at the bottom of the output shaft of the stirring motor 42 located in the storage tank. The rotating shaft 47 inside the screen plate 44 penetrates the screen plate 44. A stirring rod 48 located above the screen plate 44 is fixedly connected to the outer wall of the rotating shaft 47. A ball bearing 49 adapted to the protrusion 46 is fixedly connected to the bottom of the stirring rod 48. The powder falls onto the screen plate 44, which allows unclumped powder to pass through. When the stirring motor 42 drives the rotating shaft 47 to rotate, it can drive the stirring rod 48 to rotate. The rapid rotation of the stirring rod 48 will break up the clumped powder. At the same time, the two stirring rods 48 will drive the ball bearing 49 to rotate during the rotation. The two ball bearings 49 contact the protrusion 46, causing the screen plate 44 to press down and drive the bottom slide rod 43 to slide down along the ear block 41, and squeeze the support spring 45. After the ball bearing 49 leaves the protrusion 46, the support spring 45 pushes the screen plate 44 to reset, thereby enabling the screen plate 44 to achieve efficient shaking and quickly shake off the powder in the mesh, ensuring that the powder is broken up. The mesh plate 44 can be replaced with a ring-shaped frame on the edge and a mesh structure composed of metal wires arranged in a warp and weft pattern on the inner side. When the powder comes into contact with the metal wires, it is shaken and dispersed, ensuring the dispersion effect.

[0016] The ball bearing 49 is located at the bottom of the end of the stirring rod 48 away from the rotating shaft 47 and directly above the protrusion 46. This ensures that the ball bearing 49 forms a precise and stable contact with the protrusion 46 when rotating with the stirring rod 48. This keeps the up-and-down shaking amplitude and frequency of the screen plate 44 consistent, avoiding uneven force on the screen plate 44 due to contact position deviation, which could lead to local wear or weakened shaking effect. It also makes the entire shaking process more regular and controllable, further improving the efficiency and stability of the screen plate 44 in shaking off powder.

[0017] The screen plate 44 has a circular hole inside that corresponds to the rotating shaft 47. The rotating shaft 47 is slidably connected inside the circular hole. The diameter of the circular hole is slightly larger than the diameter of the rotating shaft 47, which provides sufficient space for the rotation of the rotating shaft 47 and avoids friction interference between the two, thus ensuring that the movement trajectory of the stirring rod 48 and the ball 49 remains stable, and further ensuring the accuracy and reliability of the shaking action of the screen plate 44.

[0018] A stirring rod 410 is fixedly connected to the outer wall of the rotating shaft 47 and is arranged longitudinally and equidistantly below the screen plate 44. The stirring rod 410 can rotate synchronously under the drive of the rotating shaft 47 to fully stir the powder falling below the screen plate 44 and evenly disperse the powder downwards. The longitudinal equidistant arrangement of the stirring rod 410 allows it to cover spatial areas of different heights during rotation, further enhancing the stirring and dispersion effect of the powder and effectively preventing uneven powder distribution in local areas.

[0019] A support 2 is installed at the bottom of the storage tank 1. Multiple weighing sensors 7 are fixedly installed in a ring at equal intervals on the top of the support 2. The support 2 presses on the multiple weighing sensors 7. The weighing sensors 7 can monitor the overall weight change of the storage tank 1 and the powder inside. Through dynamic feedback of weight data, the amount of powder to be added can be accurately calculated. When the amount of powder in the storage tank 1 decreases, the weighing sensors 7 transmit the weight signal to the PLC controller of the equipment. According to the preset addition parameters, the subsequent addition speed and time are automatically adjusted to ensure the accuracy of each addition. The design of multiple ring-shaped weighing sensors 7 can make the weight monitoring more balanced and stable, avoid measurement errors caused by uneven force at a single point, and thus further improve the accuracy and reliability of the equipment's addition and measurement.

[0020] Please see Figure 1 , Figure 4 and Figure 5 The dust collection component 5 includes a closed box 51 with a right-side opening fixedly installed on the top of the storage tank 1 and an air extractor 52. The air extractor 52 is connected to the closed box 51. A dust collection hood 53 is fixedly installed on the top of the dispersion component 4 near the closed box 51. A conveying pipe 54 is fixedly connected between the dust collection hood 53 and the closed box 51. A collection frame 55 is movably connected inside the closed box 51. A filter screen 56 is provided at the bottom of the collection frame 55. A cover plate 57 is fixedly installed on the open side of the closed box 51. The air extractor 52 draws dust into the conveying pipe 54 through the dust collection hood 53 and sends it into the closed box 51. The filter screen 56 in the collection frame 55 inside the closed box 51 can filter the dust. After the air enters the lower part of the closed box 51, it is discharged by the air extractor 52, which can effectively suppress dust and improve the working environment.

[0021] The filter 56 is made of HEPA material and is snapped into the bottom of the collection frame 55. Its edge is adapted to the slot on the inner wall of the collection frame 55. The slot structure enables quick installation and removal of the filter 56, which is convenient for operators to remove the filter 56 for cleaning or replacement regularly, ensuring long-term stable filtration effect. The size of the filter 56 matches the size of the bottom of the collection frame 55, which can completely cover the bottom area of ​​the collection frame 55, preventing unfiltered dust from entering the lower part of the sealed box 51 directly from the bottom gap of the collection frame 55, further improving the thoroughness of dust filtration.

[0022] Working principle: By feeding powder into the inside of the feeding hopper 3, the baffle at the connection between the feeding hopper 3 and the storage tank 1 is slid open to allow the powder to enter the storage tank 1. During the feeding process, the exhaust fan 52 is turned on. The exhaust fan 52 sucks the dust into the conveying pipe 54 through the dust suction hood 53 and then conveys it to the inside of the closed box 51. The dust can be filtered by the filter screen 56 inside the collection frame 55 in the closed box 51. The air entering the lower part of the closed box 51 is discharged by the exhaust fan 52, which can effectively suppress dust and improve the working environment. Later, by removing the bolts connecting the cover plate 57 to the closed box 51, the cover plate 57 can be removed, the collection frame 55 can be removed from the closed box 51, the collected dust can be cleaned, and the filter screen 56 can be replaced. After the powder enters the storage tank 1, it falls onto the mesh plate 44. The mesh plate 44 allows clumps of powder to pass through, while clumps are blocked on the mesh plate 44. The stirring motor 42 drives the rotating shaft 47 to rotate, which in turn drives the stirring rod 48 to rotate. The rapid rotation of the stirring rod 48 breaks up the clumps of powder. At the same time, the rotation of the stirring rods 48 on both sides drives the ball bearings 49 to rotate. When the ball bearings 49 on both sides contact the protrusions 46, they press down on the protrusions 46, which causes the mesh plate 44 to drive the bottom sliding rod 43 to slide downwards along the lug 41. During this process, the supporting spring 4 is compressed. 5. After the ball bearing 49 leaves the protrusion 46, the support spring 45 pushes the mesh plate 44 to reset, thereby making the mesh plate 44 vibrate efficiently to quickly shake off the powder in the mesh, ensuring the powder is dispersed. The powder enters the lower part of the storage tank 1 for storage. When in use, the electromagnetic valve at the connection between the storage tank 1 and the discharge pipe 6 is opened by electrical control, and the powder in the storage tank 1 is sucked up by negative pressure and transported to the reaction vessel through the discharge pipe 6. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
