Description
Technical Field
[0001] The utility model relates to the technical field of powder material feeding, and mainly relates to an anti-blocking and controllable feeding device. Background Art
[0002] Powders are widely used as key raw materials in numerous industrial sectors, including chemicals, building materials, and food processing. However, during the storage and transportation of these powders, ambient humidity often causes them to absorb moisture and clump, leading to "tube holes" during feeding—arched structures formed inside the silo prevent smooth flow. This severely hinders material flow and subsequent processing.
[0003] While several technical solutions exist on the market to address the problem of powder agglomeration, these solutions are complex. Furthermore, traditional powder dispensing methods typically rely on a direct connection between the barrel and the discharge port, making precise flow control difficult. Even with the addition of control valves, this approach increases equipment complexity and manufacturing costs, making it less cost-effective. Therefore, a new technical solution is urgently needed that can both effectively prevent powder agglomeration and precisely control the discharge rate. Utility Model Content
[0004] In order to solve the above technical problems, the utility model proposes an anti-blocking and controllable feeding device.
[0005] The technical solution adopted by the utility model is: a blockage-proof controllable unloading device, including a hopper, a rotating shaft rotatably arranged in the hopper, a stirring assembly installed on the rotating shaft, and a power mechanism for driving the rotating shaft to rotate, and a discharge port is provided on the bottom plate of the hopper. It is characterized in that the stirring assembly includes a stirring rod installed on the rotating shaft and a unloading cone, the unloading cone is located below the stirring rod, a notch is provided on one side of the unloading cone, and the gap between the notch and the side wall of the hopper constitutes a unloading area, the projection of the unloading area on the bottom plate of the hopper does not coincide with the position of the discharge port, and a scraper plate is fixed at the bottom of the unloading cone to push the unloading material to the discharge port.
[0006] As a preferred solution, the scraper plate is an arc-shaped structure, and the scraper plate is detachably fixed to the bottom of the blanking cone by bolts, with the convex surface of the scraper plate facing the blanking area and the concave surface facing the blanking port.
[0007] As a preferred solution, the blanking cone is provided with a groove corresponding to the rotation axis, and a limiting structure for limiting the rotation of the blanking cone is provided in the groove.
[0008] As a preferred solution, a synchronous wheel for driving the rotating shaft to rotate is provided above the rotating shaft.
[0009] As a preferred solution, the transmission mechanism includes a synchronous belt and a motor. The motor is fixed to the side wall of the silo, and the motor is connected to the synchronous wheel at the upper end of the rotating shaft through the synchronous belt.
[0010] As a preferred solution, the transmission mechanism includes a motor, which is fixed to the upper end of the silo, and the power output shaft of the motor is fixedly connected to the upper end of the rotating shaft.
[0011] As a preferred solution, the upper pressure plate is composed of a pressure plate and a feed port pressure cover, the feed port pressure cover is movably connected to the pressure plate through a hinge, and the pressure plate is fixed to the silo by bolts.
[0012] As a preferred solution, the lower gland is fixedly connected to the silo by bolts.
[0013] As a preferred solution, a plurality of reinforcing ribs are provided at the connection between the lower pressure cover and the discharge port.
[0014] The beneficial effects of the utility model are:
[0015] Based on the defects of the existing technology, the utility model provides an anti-blocking controllable feeding device. By optimizing the structural design, the utility model has the following technical effects:
[0016] First, a rotating shaft within the silo is equipped with several stirring rods, and a discharge cone is located at the lower end of the shaft. The powder placed in the silo is initially stirred by the stirring rods to break up any lumps, and then the discharge cone provides a secondary break. The stirring rods and discharge cone work together to effectively break up any lumps in the powder, significantly improving its fluidity. The rotating shaft drives the discharge cone and stirring rods to rotate synchronously, stirring the powder and breaking up any lumps that may have formed. The discharge cone further breaks up any large lumps, ensuring uniform powder flow and avoiding the problem of poor discharge caused by clumping.
[0017] Secondly, a notch is provided on one side of the discharge cone. The gap between this notch and the sidewall of the silo forms the discharge area. A scraper is fixed to the bottom of the discharge cone, pushing the material toward the discharge port. As the powder is crushed by the discharge cone and falls through the notch into the discharge area, the scraper pushes the powder from the discharge port to the discharge port as the rotating shaft rotates. Because the projection of the discharge port and the discharge port do not overlap, the powder delivery speed is controlled by controlling the rotational speed of the rotating shaft, achieving precise regulation of the powder discharge amount.
[0018] Third, the upper pressure plate above the silo and the lower pressure cover below are both fixed with bolts, which not only simplifies the assembly process but also facilitates disassembly and cleaning. At the same time, the feed inlet pressure cover on the upper pressure plate is connected by a hinge, which allows the user to easily close the feed inlet after adding materials, preventing foreign matter from entering the silo and contaminating the materials. The overall structure of this utility model is compact and easy to install and maintain.
[0019] Fourthly, reinforcing ribs are provided at the connection between the lower pressure cover and the discharge port, which enhances the stability of the structure and ensures the reliability and durability of the device in long-term operation.
[0020] Fifth, the position of the motor in the present invention can be flexibly set on the side wall of the silo or above the silo. According to the actual application scenario, the position of the motor can be changed to make the present invention suitable for different narrow locations. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1
[0029] In order to more clearly describe the specific structural composition of the anti-blocking controllable feeding device, Figure 1 Describe this embodiment:
[0030] As shown in the figure, a controllable, anti-blocking material discharge device is provided. This embodiment relates to a controllable, anti-blocking material discharge device. The device includes a silo 1, a rotating shaft 2 rotatably disposed within the silo, a stirring assembly mounted on the rotating shaft, and a power mechanism for driving the rotating shaft. A discharge port is provided on the bottom plate of the silo 1. The stirring assembly includes a stirring rod 4 mounted on the rotating shaft 2 and a discharge cone 5, which is located below the stirring rod 4. A notch is provided on one side of the discharge cone 5. The gap between the notch and the side wall of the silo forms a discharge area. The projection of the discharge area on the bottom plate of the silo 1 does not overlap with the position of the discharge port. A scraper 6 is fixed to the bottom of the discharge cone 5 to push the discharged material to the discharge port.
[0031] Several stirring rods are mounted on the rotating shaft within the silo, and a discharge cone is located at the lower end of the shaft. The powder placed in the silo is initially stirred by the stirring rods to break up any lumps, and then the discharge cone provides a secondary break. The stirring rods and discharge cone work together to effectively break up any lumps in the powder, significantly improving its fluidity. The rotating shaft drives the discharge cone and stirring rods to rotate synchronously, stirring the powder and breaking up any lumps that may have formed. The discharge cone further breaks up any large lumps, ensuring even flow.
[0032] As the powder is crushed by the discharge cone and falls through the notch in the discharge cone into the discharge area, the scraper blade pushes the powder from the discharge opening to the outlet as the rotating shaft rotates. Because the projection of the discharge opening and the outlet do not overlap, the powder delivery speed is controlled by controlling the rotation speed of the rotating shaft, achieving precise regulation of the powder discharge amount.
[0033] Furthermore, the scraper plate 6 is an arc-shaped structure, and the scraper plate 6 is detachably fixed to the bottom of the blanking cone 5 by bolts, with the convex surface of the scraper plate 6 facing the blanking area and the concave surface facing the blanking port.
[0034] The upper pressing plate 3 above the silo and the lower pressing cover 7 below are both fixed by bolts, which not only simplifies the assembly process but also facilitates disassembly and cleaning.
[0035] Furthermore, the feed port cover 11 on the upper pressure plate is movably connected by a hinge, which is convenient for the user to close the feed port after adding materials to prevent foreign matter from entering the silo and contaminating the materials. The overall structural design of the utility model is compact and easy to install and maintain.
[0036] Preferably, three reinforcing ribs are provided at the connection between the lower pressure cover 7 and the discharge port 13, which enhances the stability of the structure and ensures the reliability and durability of the device in long-term operation.
[0037] Preferably, the motor 10 is positioned at the top of the silo, reducing the width of the entire device. The power of the motor 10 is fixedly connected to the upper end of the rotating shaft 2, thereby realizing the rotation of the rotating shaft 2.
[0038] Operation process:
[0039] First, after placing the powder in silo 1, start motor 10. This rotates synchronous pulley 12 via timing belt 9, which in turn rotates shaft 2. This causes stirring rod 4 on shaft 2 to rotate, initially stirring the powder in the silo, breaking up any lumps and improving its fluidity.
[0040] In the second step, after initial stirring by stirring rod 4, the powder reaches the location of discharge cone 5. Discharge cone 5 also rotates synchronously with rotating shaft 2, further breaking up larger powder agglomerates. Because discharge cone 5 has a notch on one side, the gap between it and the silo sidewall forms a discharge area. The projection of this discharge area on the bottom plate of silo 1 does not coincide with the location of the discharge port, allowing the powder to fall into the discharge area under the action of discharge cone 5.
[0041] In the third step, the powder falling into the discharge area is pushed to the discharge port 13 by the scraper 6 fixed at the bottom of the discharge cone 5 as the rotating shaft 2 rotates. The design of the scraper 6 ensures that the powder can be evenly transported from the discharge area to the discharge port, avoiding blockage caused by powder accumulation.
[0042] Step 4: Finally, the powder is evenly crushed and pushed by the stirring rod 4 and the discharge cone 5, and is smoothly discharged from the discharge port 13, thereby achieving smooth discharge and precise control of the powder.
[0043] Example 2
[0044] In order to more clearly describe the specific structural composition of the anti-blocking controllable feeding device, Figure 1 Describe this embodiment:
[0045] As shown in the figure, a controllable, anti-blocking material discharge device is provided. This embodiment relates to a controllable, anti-blocking material discharge device. The device includes a silo 1, a rotating shaft 2 rotatably disposed within the silo, a stirring assembly mounted on the rotating shaft, and a power mechanism for driving the rotating shaft. A discharge port is provided on the bottom plate of the silo 1. The stirring assembly includes a stirring rod 4 mounted on the rotating shaft 2 and a discharge cone 5, which is located below the stirring rod 4. A notch is provided on one side of the discharge cone 5. The gap between the notch and the side wall of the silo forms a discharge area. The projection of the discharge area on the bottom plate of the silo 1 does not overlap with the position of the discharge port. A scraper 6 is fixed to the bottom of the discharge cone 5 to push the discharged material to the discharge port.
[0046] Several stirring rods are mounted on the rotating shaft within the silo, and a discharge cone is located at the lower end of the shaft. The powder placed in the silo is initially stirred by the stirring rods to break up any lumps, and then the discharge cone provides a secondary break. The stirring rods and discharge cone work together to effectively break up any lumps in the powder, significantly improving its fluidity. The rotating shaft drives the discharge cone and stirring rods to rotate synchronously, stirring the powder and breaking up any lumps that may have formed. The discharge cone further breaks up any large lumps, ensuring even flow.
[0047] As the powder is crushed by the discharge cone and falls through the notch in the discharge cone into the discharge area, the scraper blade pushes the powder from the discharge opening to the outlet as the rotating shaft rotates. Because the projection of the discharge opening and the outlet do not overlap, the powder delivery speed is controlled by controlling the rotation speed of the rotating shaft, achieving precise regulation of the powder discharge amount.
[0048] Furthermore, the scraper plate 6 is an arc-shaped structure, and the scraper plate 6 is detachably fixed to the bottom of the blanking cone 5 by bolts, with the convex surface of the scraper plate 6 facing the blanking area and the concave surface facing the blanking port.
[0049] Furthermore, the feed port cover 11 on the upper pressure plate is movably connected by a hinge, which is convenient for the user to close the feed port after adding materials to prevent foreign matter from entering the silo and contaminating the materials. The overall structural design of the utility model is compact and easy to install and maintain.
[0050] The upper pressing plate 3 above the silo and the lower pressing cover 7 below are both fixed by bolts, which not only simplifies the assembly process but also facilitates disassembly and cleaning.
[0051] Preferably, three reinforcing ribs are provided at the connection between the lower pressure cover 7 and the discharge port 13, which enhances the stability of the structure and ensures the reliability and durability of the device in long-term operation.
[0052] Preferably, the motor 10 is positioned on the side wall of the silo to reduce the length of the entire device. The motor is connected to the synchronous wheel 12 at the upper end of the rotating shaft through a synchronous belt 9, thereby realizing the rotation of the rotating shaft 2.
[0053] Operation process:
[0054] First, after placing the powder in silo 1, start motor 10. This rotates synchronous pulley 12 via timing belt 9, which in turn rotates shaft 2. This causes stirring rod 4 on shaft 2 to rotate, initially stirring the powder in the silo, breaking up any lumps and improving its fluidity.
[0055] In the second step, after initial stirring by stirring rod 4, the powder reaches the location of discharge cone 5. Discharge cone 5 also rotates synchronously with rotating shaft 2, further breaking up larger powder agglomerates. Because discharge cone 5 has a notch on one side, the gap between it and the silo sidewall forms a discharge area. The projection of this discharge area on the bottom plate of silo 1 does not coincide with the location of the discharge port, allowing the powder to fall into the discharge area under the action of discharge cone 5.
[0056] In the third step, the powder falling into the discharge area is pushed to the discharge port 13 by the scraper 6 fixed at the bottom of the discharge cone 5 as the rotating shaft 2 rotates. The design of the scraper 6 ensures that the powder can be evenly transported from the discharge area to the discharge port, avoiding blockage caused by powder accumulation.
[0057] Step 4: Finally, the powder is evenly crushed and pushed by the stirring rod 4 and the discharge cone 5, and is smoothly discharged from the discharge port 13, thereby achieving smooth discharge and precise control of the powder.
[0058] It should be noted that although the present invention has been described through the above embodiments, the present invention may also have other various embodiments. Without departing from the spirit and scope of the present invention, it is obvious that those skilled in the art may make various corresponding changes and modifications to the present invention, and such changes and modifications shall fall within the scope of protection of the appended claims and their equivalents.
