Description

Technical Field

[0001] This utility model relates to the field of powder storage technology, specifically a powder silo unblocking device. Background Technology

[0002] In the processing, manufacturing, storage, and transportation of mineral powders, storage silos are essential equipment. A key characteristic of mineral powders stored in silos is that their flowability deteriorates with prolonged settling time; the longer the settling time, the worse the flowability, potentially leading to agglomeration, caking, and loss of flowability. To ensure stable flow of powder within the silo, a silo unblocker is used to agitate the powder and improve its flowability. A powder silo unblocker is a device used in powder material storage silos to help unclog blockages and maintain material flowability. It is commonly found in powder warehouses, silos, and hoppers, especially when handling powdery or granular materials. The unblocker's function is to allow material to flow smoothly through mechanical, pneumatic, or vibration methods, preventing blockages and downtime caused by material accumulation or agglomeration.

[0003] In the process of clearing powder inside a silo, a stirring device is installed in the middle of the silo to loosen the powder and prevent it from solidifying and becoming stuck. However, the outlet of the silo is usually located at the bottom, which means that the clearing device can only clear the powder in the middle. When the powder solidifies inside the silo, it cannot flow to the middle, resulting in a decrease in the clearing efficiency of the device. Therefore, we propose a powder silo clearing device. Utility Model Content

[0004] To address the shortcomings of existing powder silo unclogging devices, this invention provides a powder silo unclogging device that utilizes a starting motor to drive the unclogging device housing and agitator blades to rotate, thereby controlling the unclogging device housing and agitator blades to unclog the powder accumulated inside the silo. Simultaneously, the position of the slider inside the horizontal plate can be adjusted by rotating the rotating seat, i.e., the position of the agitator blades inside the silo can be adjusted, ensuring that the unclogging device can unclog powder in different locations inside the silo, thus improving the unclogging efficiency of the device and solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a powder silo unblocking device, including a silo, a threaded cover is installed on the external thread of the upper end of the silo, a rotating seat is movably sleeved on the inner side of the threaded cover, two sets of lead screws are installed on the internal thread of the rotating seat, a cross plate is provided at the lower end of the lead screws to control the lateral movement of the slider, an installation plate is movably sleeved inside the slider, a rotating column is fixedly connected to the middle of the installation plate, a conical tip is fixed at the lower part of the rotating column, a stirring blade is fixed to the outside of the rotating column, and an unblocking device shell for unblocking powder is installed inside the stirring blade.

[0006] Preferably, the rotating seat is located at the upper end of the hopper, and a bearing is installed between the threaded cover and the rotating seat.

[0012] Compared with existing powder silo unclogging devices, this utility model has the following advantages: 1. This powder silo unclogging device has an outer casing installed on the outside of the mixing blades. The mixing blades reinforce the unclogging casing. At the same time, the rotating column drives the unclogging casing and mixing blades to rotate, and the unclogging casing and mixing blades effectively mix the powder. Meanwhile, the inside of the unclogging casing has a gas flow channel and a vent. During the mixing process of the mixing blades, the unclogging casing drives the gas to flow.

[0016] 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.

[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A powder silo unclogging device includes a silo 1. A threaded cover 2 is threaded onto the external thread of the upper end of the silo 1. A rotating seat 3 is movably sleeved on the inner side of the threaded cover 2. The threaded cover 2 is installed on the outside of the silo 1. Rotating the rotating seat 3 allows adjustment of the device's angle. Two sets of lead screws 4 are threaded onto the internal thread of the rotating seat 3. A horizontal plate 5 is provided at the lower end of the lead screws 4 to control the lateral movement of a slider 6. Adjusting the position of the slider 6 outside the horizontal plate 5 allows adjustment of the unclogging device's position inside the silo 1. The slider 6 is movably sleeved with... Mounting plate 7, with a rotating column 8 fixedly connected to the middle of mounting plate 7. When motor 11 is started, motor 11 drives rotating column 8 to rotate. At the same time, hopper 1 drives drain cleaner housing 13 and stirring blade 14 to rotate. That is, drain cleaner housing 13 and stirring blade 14 drive powder to be stirred inside hopper 1, thereby playing the role of unblocking powder. A conical tip 12 is fixed at the lower part of rotating column 8, and stirring blade 14 is fixed on the outside of rotating column 8. Drain cleaner housing 13 for unblocking powder is installed inside stirring blade 14.

[0018] Please see Figure 2 The rotating seat 3 is located at the upper end of the hopper 1, and a bearing is installed between the threaded cover 2 and the rotating seat 3. The threaded cover 2 is threaded onto the outside of the hopper 1, that is, the threaded cover 2 drives the rotating seat 3 to be installed at the upper end of the hopper 1. The bearing installed between the threaded cover 2 and the rotating seat 3 reduces the frictional resistance of the rotating seat 3. Thus, when the rotating seat 3 rotates, the position of the dredging equipment inside the hopper can be adjusted to ensure that the equipment can dredge the hopper from all directions.

[0019] Please see Figure 3 The slider 6 is movably sleeved inside the groove on the inner side of the horizontal plate 5. The two ends of the horizontal plate 5 are attached to the inner side of the hopper 1. By rotating the screw 4, the depth of the horizontal plate 5 inside the hopper can be adjusted. The slider 6 is pushed and its position inside the horizontal plate 5 is adjusted laterally, so that the position of the unblocking equipment can be adjusted, ensuring the convenience of unblocking position adjustment.

[0020] Please see Figure 3 A protective cover 15 is provided on the outside of the rotating column 8 and on the upper part of the drain cleaner housing 13 to protect the powder. The protective cover 15 is circular on the outside of the rotating column 8. The protective cover 15 is located on the upper end of the drain cleaner housing 13. During the process of drain cleaner housing 13 and stirring blade 14 clearing the powder, the dust falls to all sides. At the same time, the protective cover 15 is located on the upper part of drain cleaner housing 13 and stirring blade 14 to prevent the dust from spreading everywhere.

[0021] Please see Figure 4A first gear 9 is fixed to the outside of the upper end of the mounting plate 7. A motor 11 is installed on one side of the upper part of the slider 6. The gear installed at one end of the output shaft of the motor 11 meshes with the outside of the first gear 9. By starting the motor 11, the motor 11 meshes with the first gear 9, controlling the rotation of the first gear 9. The first gear 9 drives the rotating column 8 to rotate. The rotating column 8 drives the drain cleaner housing 13 and the stirring blades 14 to stir the powder accumulated inside the hopper 1, ensuring that the powder is unblocked and avoiding the problem of powder accumulation leading to solidification.

[0022] Please see Figure 4 A gas injection pipe 10 is installed at the top of the rotating column 8. The rotating column 8 has a through hole that is connected to the inside of the gas injection pipe 10. An air pump is installed on the outside of the gas injection pipe 10. By controlling the gas injection pipe 10 to be connected to the upper end of the rotating column 8, the air pump installed on the outside of the gas injection pipe 10 is started. The air pump drives the gas to flow, that is, the gas is injected into the interior of the rotating column 8 through the gas injection pipe 10. At the same time, the rotating column 8 injects gas into the interior of the stirring blade 14. That is, the gas can blow the powder in the stirring process. By blowing the powder, the powder clearing efficiency is improved.

[0023] Please see Figure 5 The drain cleaner housing 13 includes a reinforcing plate 131. The interior of the reinforcing plate 131 has a gas flow channel 132, which is connected to the through hole inside the rotating column 8. The exterior of the reinforcing plate 131 has equidistant air outlets 133. With the gas flow channel 132 installed inside the reinforcing plate 131, the rotating column 8 drives the gas to enter through the gas flow channel 132 and simultaneously discharge through the air outlets 133. That is, the air outlets 133 drive the gas to circulate inside the powder, thereby controlling the mixing and unblocking of the powder inside the hopper 1 and improving the powder separation efficiency.

[0024] Working principle: In use, by installing the threaded cap 2 on the upper part of the hopper 1, the rotating column 8 is extended into the hopper 1 and inserted into the material pile through the conical tip 12. The motor 11 is started, and the motor 11 drives the rotating column 8 to rotate. The rotating column 8 drives the unblocker housing 13 and the stirring blades 14 to stir the material pile. At the same time, the gas injection pipe 10 injects gas, which is then injected into the stirring blades 14 through the rotating column 8. The stirring blades 14 drive the gas to spray out, i.e., the gas blows through the powder pile, improving the fullness of powder unblocking. At the same time, the rotating seat 3 is rotated, the lead screw 4 is rotated, and the height of the stirring blades 14 is adjusted. The position of the slider 6 outside the horizontal plate 5 is also adjusted, so that the position of the unblocking device can be precisely adjusted, thereby improving the accuracy of the unblocking positioning of the equipment.

[0025] 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.
