Description

Technical Field

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

[0002] The dipentaerythritol silo automated feeding device is an automated equipment specifically designed for the storage and quantitative feeding of dipentaerythritol (a hygroscopic and easily agglomerated powder or granular material) in the chemical and pharmaceutical industries.

[0003] Existing technologies mostly employ a single screw conveyor mechanism or gravity feeding mode, lacking adaptive designs for material properties (such as hygroscopicity and tendency to caking). Furthermore, gravity feeding relies on manual adjustment of valve opening, making it difficult to achieve precise quantitative control.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the existing technology uses a single screw conveyor mechanism or gravity feeding mode, which is inconvenient to convey when the material has high hygroscopicity and is prone to agglomeration, and it is difficult to achieve accurate quantitative control by manually adjusting the valve opening.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a bispentaerythritol silo self-controlled feeding device, including a silo feeding mounting frame, a silo self-controlled feeding component inside the silo feeding mounting frame, an anti-caking component on one side of the silo self-controlled feeding component, and a feeding weighing component below the self-controlled feeding component;

[0007] To achieve the function of automatic feeding, the automatic feeding assembly includes an automatic feeding hopper, which is connected to the material hopper feeding mounting frame. A fixed mounting plate is installed inside the automatic feeding hopper, and a rotating shaft is movably connected inside the fixed mounting plate. Spiral feeding blades are installed around the rotating shaft. A feeding pipe is connected to the bottom of the automatic feeding hopper, and a feeding stop valve is installed inside the feeding pipe. A rotating shaft limit plate is movably connected to the bottom of the rotating shaft through a sealed bearing, and the rotating shaft limit plate is fixedly connected to the feeding pipe.

[0008] Furthermore, a discharge controller is installed on one side of the hopper discharge mounting frame, and the discharge stop valve is electrically connected to the discharge controller.

[0009] Furthermore, in order to achieve the function of preventing caking, the anti-caking component includes an active bevel gear, which is connected to a rotating shaft. A driven bevel gear is symmetrically meshed around the active bevel gear. One end of the driven bevel gear is connected to a dispersing rod. Both ends of the rotating shaft of the dispersing rod are movably connected to the limiting plate of the rotating shaft of the dispersing rod. The limiting plate of the rotating shaft of the dispersing rod is connected to a fixed mounting plate.

[0010] Furthermore, in order to achieve the function of weighing the material, the material weighing component includes a weighing housing, which is connected to the material hopper mounting frame through a weighing sensor. A discharge pipe is installed below the weighing housing, and a discharge valve is installed inside the discharge pipe.

[0011] Furthermore, the discharge valve and the discharge controller are electrically connected.

[0012] Furthermore, the material unloading mounting frame of the hopper has a through slot inside.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model improves upon existing technologies. In practical use, by using a silo self-controlled feeding component and an anti-caking component, it solves the problem that existing technologies often employ a single screw conveyor mechanism or gravity feeding mode, lacking adaptive design for material properties (such as hygroscopicity and easy agglomeration). Furthermore, gravity feeding relies on manual adjustment of valve opening, making it difficult to achieve precise quantitative control.

[0015] 2. The hopper unloading mounting frame achieves quick docking with external equipment via a through-slot. Its frame is reinforced with welded carbon steel, providing sufficient support for continuous operation with heavy-duty materials. The combination of the rotating shaft limit plate and sealed bearing ensures the axial stability of the rotating shaft without hindering material passage. Attached Figure Description

[0026] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example

[0027] like Figure 1-4 As shown, this utility model provides a bispentaerythritol silo self-controlled feeding device, including a silo feeding mounting frame 1, a silo self-controlled feeding component 2 inside the silo feeding mounting frame 1, an anti-caking component 3 on one side of the silo self-controlled feeding component 2, and a feeding weighing component 4 below the self-controlled feeding component 2.

[0028] like Figure 1-4As shown, according to an embodiment of the present invention, the self-controlled feeding device for the dipentaerythritol silo includes a self-controlled feeding hopper 201 connected to a silo feeding mounting frame 1. A fixed mounting plate 202 is installed inside the self-controlled feeding hopper 201, and a rotating shaft 203 is movably connected inside the fixed mounting plate 202. A spiral feeding blade 204 is installed around the rotating shaft 203. A feeding pipe 205 is connected to the bottom of the self-controlled feeding hopper 201, and a feeding stop valve 206 is provided inside the feeding pipe 205. The rotating shaft 203 is connected to a rotating shaft limiting plate 208 via a sealed bearing 207 below it. The rotating shaft limiting plate 208 is fixedly connected to the feeding pipe 205. A feeding controller 5 is provided on one side of the silo feeding mounting frame 1, and the feeding stop valve 206 and the feeding controller 5 are electrically connected.

[0029] Through the above technical solution, materials enter the device through the self-controlled feeding hopper 201, and the fixed mounting plate 202 is installed inside the feeding hopper as a supporting structure. The rotating shaft 203 is driven to rotate by a motor, which is mounted on the fixed mounting plate 202. The spiral feeding blades 204 welded around the rotating shaft 203 use the spiral propulsion principle to directionally convey the material to the feeding pipe 205. In this process, the material flow rate can be dynamically controlled by controlling the rotation speed of the spiral feeding blades 204, and the material feeding metering can be achieved by controlling the number of times the shut-off valve 206 is opened. Example

[0030] like Figure 1-4 As shown, this embodiment is based on Embodiment 1 and describes the anti-caking component 3 in detail: The anti-caking component 3 includes an active bevel gear 301, which is connected to a rotating shaft 203. A driven bevel gear 302 is symmetrically meshed around the active bevel gear 301. One end of the driven bevel gear 302 is connected to a dispersing rod 303. A dispersing rod rotating shaft limiting plate 304 is movably connected around the dispersing rod 303. The dispersing rod rotating shaft limiting plate 304 is connected to a fixed mounting plate 202. The dispersing rod 303 and the rotating shaft 203 are movably connected to the limiting plate through a sealed bearing 207.

[0031] Through the above technical solution, during material conveying, the driving bevel gear 301 rotates synchronously with the rotating shaft 203, driving the symmetrically distributed driven bevel gears 302 to rotate in the opposite direction, which in turn drives the two dispersing rods 303 to rotate under the constraint of the dispersing rod rotating shaft limiting plate 304. The protruding structure on the surface of the dispersing rods 303 performs high-frequency impact crushing of the material, effectively preventing the agglomeration of dipentaerythritol due to changes in humidity or temperature.

[0032] The connection between the rotating shaft 203, the dispersing rod 303, and the limiting plate (rotating shaft movable limiting plate 208 and dispersing rod rotating shaft limiting plate 304) is connected by a sealed bearing to prevent material from entering the transmission mechanism. Example

[0033] like Figure 1-4 As shown, this embodiment is based on the second embodiment and describes the material feeding and weighing component 4 in detail: The material feeding and weighing component 4 includes a weighing housing 401, which is connected to the material hopper feeding mounting frame 1 through a weighing sensor 402. A discharge pipe 403 is installed below the weighing housing 401, and a discharge valve 404 is installed inside the discharge pipe 403. The discharge valve 404 is electrically connected to the controller 5. A through slot 6 is opened inside the material hopper feeding mounting frame 1.

[0034] Through the above technical solution, the material conveyed by the spiral feeder 204 enters the weighing housing 401 through the feed pipe 205. The weighing sensor 402 sends an electrical signal to the feed controller 5. When the material reaches the preset weight, the feed controller 5 simultaneously closes the feed stop valve 206 and opens the discharge valve 404, and the material is discharged through the discharge pipe 403. The entire process forms a closed-loop control, ensuring that the feeding accuracy error is less than ±0.5%.

[0035] The material unloading mounting frame 1 of the hopper achieves quick docking with external equipment through the through slot 6. Its frame adopts a reinforced carbon steel welded design, and its support strength meets the requirements of continuous operation of heavy-duty materials. The combination structure of the rotating shaft limiting plate 208 and the sealed bearing 207 ensures the axial stability of the rotating shaft 203 without affecting the passage of materials (a cross structure can be used, with a bearing mounting hole in the middle of the cross and the two ends of the cross connected to the unloading pipe 205).

[0036] The overall technical solution formed by the above embodiments is used as follows: Material enters the device through the self-controlled feeding hopper 201 of the silo. The fixed mounting plate 202 is installed inside the feeding hopper as a support structure. The rotating shaft 203 is driven to rotate by a motor, and the spiral feeding blades 204 welded to its periphery convey the material to the feeding pipe 205 through the spiral propulsion principle. During this process, the pitch and rotation speed of the spiral feeding blades 204 are adjusted by the controller 5 through preset parameters to achieve dynamic control of the material flow rate.

[0037] During material conveying, the active bevel gear 301 rotates synchronously with the rotating shaft 203, driving the symmetrically distributed driven bevel gears 302 to rotate in the opposite direction, which in turn drives the two dispersing rods 303 to rotate under the constraint of the dispersing rod rotating shaft limiting plate 304. The protruding structure on the surface of the dispersing rods 303 performs high-frequency impact and crushing of the material, effectively preventing the clumping of dipentaerythritol due to humidity or temperature changes. The connection between the rotating shaft 203 and the dispersing rods 303 and the limiting plate is made of sealed bearings 207, which can prevent the material from entering the transmission mechanism.

[0038] The material conveyed by the spiral feeder 204 enters the weighing housing 401 through the feed pipe 205. When the material reaches the preset weight, the weighing sensor 402 sends an electrical signal to the controller 5. The controller 5 simultaneously closes the feed stop valve 206 and opens the discharge valve 404. The material is discharged through the discharge pipe 403. The whole process forms a closed-loop control to ensure that the feeding accuracy error is less than ±0.5%.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
