Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a feeding system for fluorine-containing alumina storage silos. Background Technology

[0002] Fluorinated alumina storage silos are key equipment in aluminum electrolysis production. They are used to store alumina after it has been purified by a flue gas purification system to adsorb fluorides. They are usually designed with a double-layer structure, with the upper layer storing fluorinated alumina and the lower layer storing fresh alumina. Material conveying is achieved by a pneumatic elevator. The storage silos are equipped with a dust removal system that uses high-efficiency bag filters to reduce dust emissions, ensure environmental compliance, and maintain stable system operation. In real-world working environments, when feeding fluorinated alumina storage silos, the materials often arrive at the factory in bagged form, requiring manual labor to open the packaging bags with tools such as knives or scissors before pouring the alumina into the inlet. This process is not only inconvenient and inefficient, but also prone to incomplete feeding due to dust leakage. Therefore, this utility model proposes a fluorinated alumina storage silo feeding system to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a fluorinated alumina storage and feeding system to solve the issues of inconvenience and low efficiency in the existing technology of manually opening bags and emptying fluorinated alumina upon arrival at the factory.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a fluorine-containing alumina storage silo feeding system, including a fixed frame, a conveying pipe and a discharge hopper. The conveying pipe is fixedly installed on the top of the fixed frame, and the discharge hopper is fixedly installed at one end of the conveying pipe. A feeding hopper is fixedly connected to one side of the discharge hopper, and a connecting frame is fixedly connected to one side of the top of the feeding hopper. A crushing mechanism is provided on the connecting frame, and a collecting mechanism is provided on one side of the discharge hopper.

[0005] A further improvement is that the material breaking mechanism includes a connecting frame, a ejector pin, a rotating shaft, a knob, and a spring. The ejector pin is slidably connected inside the connecting frame. The bottom end of the ejector pin is hinged to a knob via the rotating shaft, and a spring is sleeved on the bottom end of the ejector pin.

[0006] A further improvement is that the top of the knob is designed as an arc structure, the top of the ejector pin is designed as a cone structure, and a collection hopper is fixedly installed on one side of the feed hopper.

[0007] A further improvement is that a motor is fixedly installed at one end of the conveying pipe, and an auger is rotatably connected inside the conveying pipe. The output end of the motor is fixedly connected to one end of the auger.

[0008] A further improvement is that one end of the auger extends into the interior of the hopper, and the bottom of the hopper is connected to a discharge pipe.

[0009] A further improvement is that the material collection mechanism includes an air pump, a filter, and an air pipe. An air pump is fixedly installed on one side of the hopper. The input end of the air pump is connected to the filter. One end of the filter is connected to the inside of the hopper. The output end of the air pump is connected to an elbow pipe. The material collection hopper is connected to the inside of the hopper through an air supply pipe.

[0010] A further improvement is that the motor is provided with a protective shell on its outer side, and multiple anti-collision strips are fixedly connected to the outer side of the protective shell. The anti-collision strips are rectangular in shape.

[0011] The beneficial effects of this utility model are as follows: the connecting frame restricts the movement trajectory of the ejector pin. Turning the knob downwards causes the ejector pin to move downwards. At this time, the spring on the ejector pin is in a compressed state. The plastic bag containing fluorinated alumina powder is placed on the top of the feed hopper. Then, turning the knob upwards causes the ejector pin to move upwards. The tip of the ejector pin pierces the inside of the packaging bag, drags the plastic bag and completely tears it open, allowing the fluorinated alumina powder to enter the inside of the feed hopper. After the knob is completely released, the elastic force generated by the spring causes the ejector pin to move upwards to reset it. This solves the problem of inconvenience and low efficiency of manually breaking and emptying fluorinated alumina bags after they are delivered to the factory in the prior art.

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1-5As shown, this embodiment proposes a fluorinated alumina storage and feeding system, including a fixed frame 1, a conveying pipe 2, and a discharge hopper 3. The conveying pipe 2 is fixedly installed on the top of the fixed frame 1, and the discharge hopper 3 is fixedly installed at one end of the conveying pipe 2. A feed hopper 4 is fixedly connected to one side of the discharge hopper 3, and a connecting frame 5 is fixedly connected to one side of the top of the feed hopper 4. The connecting frame 5 is equipped with a breaking mechanism, and a collecting mechanism is equipped on one side of the discharge hopper 3. A plastic bag containing fluorinated alumina powder is placed on the top of the feed hopper 4, and the breaking mechanism breaks the plastic bag open. The fluorinated alumina powder flows along the feed hopper 4 into the interior of the conveying pipe 2, and is then conveyed to the discharge hopper 3 for feeding as needed through the conveying pipe 2. The collecting mechanism can collect the airborne fluorinated alumina powder and convey it to the interior of the discharge hopper 3.

[0016] The breaking mechanism includes a connecting frame 5, a pin 6, a rotating shaft 7, a knob 8, and a spring 9. The pin 6 is slidably connected inside the connecting frame 5. The bottom end of the pin 6 is hinged to the knob 8 via the rotating shaft 7. The bottom end of the pin 6 is fitted with a spring 9. The top end of the knob 8 is an arc structure, and the top end of the pin 6 is a conical structure. The connecting frame 5 restricts the movement trajectory of the pin 6. Rotating the knob 8 downwards causes the pin 6 to move downwards. At this time, the spring 9 on the pin 6 is in a compressed state. A plastic bag containing fluorinated alumina powder is placed on top of the feed hopper 4. Then, rotating the knob 8 upwards causes the pin 6 to move upwards. The top end of the pin 6 pierces the inside of the packaging bag, dragging the plastic bag to completely rupture it. The fluorinated alumina powder enters the inside of the feed hopper 4. After the knob 8 is completely released, the elastic force generated by the spring 9 causes the pin 6 to move upwards to reset.

[0017] A motor 11 is fixedly installed at one end of the conveying pipe 2. An auger 10 is rotatably connected inside the conveying pipe 2. The output end of the motor 11 is fixedly connected to one end of the auger 10. One end of the auger 10 extends into the interior of the feeding hopper 3. The bottom of the feeding hopper 3 is connected to the feeding pipe 17. The output end of the motor 11 can drive the auger 10 to rotate inside the conveying pipe 2. The spiral blades on the outside of the auger 10 drive the fluorine-loaded alumina powder to move towards the interior of the feeding hopper 3. After the fluorine-loaded alumina powder falls into the interior of the feeding hopper 3, it is fed downward through the feeding pipe 17.

[0018] A collecting hopper 15 is fixedly installed on one side of the feeding hopper 4. The collecting mechanism includes an air pump 12, a filter 13, and an air pipe 14. An air pump 12 is fixedly installed on one side of the discharging hopper 3. The input end of the air pump 12 is connected to the filter 13. One end of the filter 13 is connected to the inside of the discharging hopper 3. The output end of the air pump 12 is connected to an elbow pipe. The collecting hopper 15 is connected to the inside of the discharging hopper 3 through an air supply pipe 16. The air pump 12 and the air pipe 14 work together to draw air from the inside of the discharging hopper 3 to create a negative pressure state. The suction force is generated inside the discharging hopper 3 by the air pressure difference. The inside of the discharging hopper 3 is connected to the collecting hopper 15 through the air supply pipe 16. The collecting hopper 15 draws in the air-floating fluorinated alumina powder and transports it to the inside of the discharging hopper 3 through the air supply pipe 16. The air pipe 14 can separate the air from the fluorinated alumina powder to prevent the fluorinated alumina powder from entering the inside of the air pump 12 and causing damage.

[0019] The motor 11 is provided with a protective shell on its outer side. Multiple anti-collision strips are fixedly connected to the outer side of the protective shell. The anti-collision strips are rectangular in shape. The protective shell and anti-collision strips can wrap around the motor 11 to prevent the motor 11 from directly contacting external objects and thus protect the motor 11.

[0020] In this fluorinated alumina storage hopper feeding system, the connecting frame 5 restricts the movement trajectory of the ejector pin 6. Turning the knob 8 downwards causes the ejector pin 6 to move downwards. At this time, the spring 9 on the ejector pin 6 is in a compressed state. The plastic bag containing fluorinated alumina powder is placed on top of the feed hopper 4. Then, turning the knob 8 upwards causes the ejector pin 6 to move upwards. The tip of the ejector pin 6 pierces the inside of the packaging bag, dragging the plastic bag to completely puncture it, and the fluorinated alumina powder enters the inside of the feed hopper 4. After the knob 8 is completely released, the elastic force generated by the spring 9 causes the ejector pin 6 to move upwards to reset.
