Description

Technical Field

[0001] The present application relates to the technical field of feeding devices, and in particular to a solid feeding and dust removal device. Background Art

[0002] Solid material feeding is a common material feeding method in industrial production.

[0003] In actual industrial production, solid materials are typically packed in bags. These are flexible transport containers typically made from polyester fibers such as polypropylene and polyethylene. These bags are moisture-proof, dust-proof, durable, and secure. Their structural strength makes them easy to load, unload, and transport, significantly improving loading and unloading efficiency. The materials in the bags then need to be transferred to the raw material bin for subsequent processing.

[0004] Regarding the aforementioned technologies, materials are typically dumped directly into the raw material bin manually. During this dumping process, due to the small size and light weight of these dust particles, solid dust easily diffuses and transmits in the air, potentially posing a health hazard to surrounding workers and increasing the potential safety risk of dust explosions. Therefore, improvements are needed. Utility Model Content

[0005] In order to reduce the spillage of solid feed dust into the air and reduce the risk of dust explosion, the present application provides a solid feed dust removal device.

[0006] The solid feeding dust removal device provided in this application adopts the following technical solution:

[0007] A solid feeding dust removal device comprises a suction gun, a raw material bin, a material-gas separator, a pressure transmitter and a Roots vacuum pump, wherein the suction gun is connected to the raw material bin and is used to transport the material into the raw material bin; the material-gas separator is arranged at the connection position between the raw material bin and the suction gun, and is used to intercept solid material; the Roots vacuum pump is connected to the material-gas separator and is used to discharge gas; the pressure transmitter is arranged between the material-gas separator and the Roots vacuum pump and is used to convert pressure changes into electrical signals or other types of output signals.

[0008] By adopting this technical solution, during operation, a vacuum suction gun transfers material from the material bag to the raw material silo. A gas separator installed on the top of the silo intercepts the solid material, allowing the gas to be discharged by the Roots vacuum pump. During the feeding process, the material and dust are sucked into the suction gun together, thereby reducing the escape of dust into the surrounding work environment, thereby reducing the health hazards to workers and the risk of dust explosions.

The pressure-surge tank can maintain the air pressure in the return air pipe, and finally flows back to the weighing silo along the return air pipe, realizing the recycling of the carrier gas. The entire system is closed.

[0015] Preferably, a cooler is further included, which is arranged between the purification dust collector and the pressure-surge tank and is used to cool the carrier gas after dust removal. The cooler is provided with a water inlet and a water outlet.

The user kettle is connected to the weighing silo through the material delivery pipeline. The screw conveyor is arranged at the bottom of the weighing silo and is used to transport materials; the vibrator is arranged on the material delivery pipeline and is used to vibrate the material.

[0018] By adopting the above technical solution, the materials after quantitative weighing are transported along the material delivery pipe to the user's kettle for reaction under the action of the screw conveyor.

[0035] Some embodiments of the present application are described in detail below with reference to the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine the different embodiments or examples and features of the different embodiments or examples shown in the present application.

[0036] The embodiment of the present application discloses a solid feeding dust removal device. Figure 1 and Figure 2The dust removal device includes a cage shaft 1, an electric hoist 2, a suction gun 3, a raw material bin 4, a material-gas separator 5, a pressure transmitter 6 and a Roots vacuum pump 7. The cage shaft 1 is vertically arranged and is used for stacking material bags. The raw material bin 4 is located on one side of the cage shaft 1 and is used to store materials. The electric hoist 2 is located between the cage shaft 1 and the raw material bin 4 and is used to lift the material bags in the cage shaft 1 so that the material bags are transported to the vicinity of the raw material bin 4. There is no need to rely on manual labor to move the material bags, thereby reducing the labor intensity of personnel.

[0037] A suction lance 3 is connected to a raw material bin 4 and is used to transport the material into the bin 4. A gas separator 5 is installed at the junction of the bin 4 and the suction lance 3 to intercept solid material. A Roots vacuum pump 7 is connected to the gas separator 5 and is used to exhaust gas. A pressure transmitter 6 is installed between the gas separator 5 and the Roots vacuum pump 7. The pressure transmitter 6 is conventional and is used to convert pressure changes into electrical signals or other types of output signals. A detailed description of the pressure transmitter 6 is omitted here.

[0038] During operation, a vacuum suction gun 3 transfers material from the material bag to the raw material bin 4. A gas separator 5, located on top of the raw material bin 4, intercepts the solid material, allowing the gas to be discharged by a Roots vacuum pump 7. During the feeding process, the material and dust are sucked in together by the suction gun 3, thereby reducing the escape of dust into the surrounding work environment, thereby minimizing the health hazards to workers and reducing the risk of dust explosions.

[0039] Specifically, a weighing silo 8 is located below the raw material silo 4 for weighing the materials. A rotary discharge valve 13 is installed at the bottom of the raw material silo 4 to control the discharge of the materials. During production, the rotary discharge valve 13 can be controlled to establish communication between the raw material silo 4 and the weighing silo 8, allowing the materials in the raw material silo 4 to be transported to the weighing silo 8. The weighing silo then weighs the materials for subsequent quantitative processing and production. When the weight of the materials in the weighing silo 8 reaches the set value, the rotary discharge valve 13 is controlled to stop the discharge of the materials.

[0040] The weighing silo 8 is equipped with a filter 9, a dust purifier 10, and a surge tank 11 along the flow of gas. The filter 9 is installed on the top of the weighing silo 8 and is used to remove impurities from the carrier gas. The dust purifier 10 is connected to the filter 9 and is used to remove dust from the cleaned carrier gas. The surge tank 11 is connected to the output of the dust purifier 10. The surge tank 11 and the weighing silo 8 are connected by a return air pipe 12, which is used to return the carrier gas to the weighing silo 8 to balance the air pressure.

[0041] The fixed material is transported from the raw material bin 4 to the weighing bin 8 using a vacuum pump. The carrier gas passes through the filter 9 and the dust collector 10 on the top of the weighing bin 8 in sequence. After the carrier gas is cleaned of impurities and dust, it enters the surge tank 11. The presence of the surge tank 11 can stabilize the air pressure in the return pipe 12. Finally, the carrier gas flows back to the weighing bin 8 along the return pipe 12, realizing the recycling of the carrier gas and making the entire system airtight.

[0042] In some embodiments, a cooler 14 is further installed between the dust collector 10 and the surge tank 11. The cooler 14 is used to cool the carrier gas after dust removal. The cooler 14 is water-cooled and has a water inlet 15 and a water outlet 16. The cooler 14 can cool the carrier gas after dust removal, thereby better controlling the carrier gas pressure and preventing excessive carrier gas pressure.

[0043] Combine Figure 3 In addition, a user kettle 17 is located below the weighing silo 8 and is connected to the weighing silo 8 via a feed pipe 19. A screw conveyor 18 is installed at the bottom of the weighing silo 8 to transport materials. A vibrator 20 is also installed on the feed pipe 19 to vibrate the material within the feed pipe 19. After quantitative weighing, the material is transported along the feed pipe 19 to the user kettle 17 for reaction under the action of the screw conveyor 18. During the feeding process, the vibrator 20 generates a vibration force on the feed pipe 19, which helps the material enter the user kettle 17 more effectively.

[0044] A centralized dust collector 21 and an induced draft fan 22 are also provided on one side of the user kettle 17. The centralized dust collector 21 is used to connect the user kettle 17 and the induced draft fan 22. The induced draft fan 22 is used to exhaust the air in the user kettle 17. The air exhausted from the user kettle 17 is first removed by the dust collector and finally discharged into the atmosphere by the induced draft fan 22, thereby reducing pollution to the atmosphere.

[0045] The implementation principle of a solid feeding and dust removal device in an embodiment of the present application is as follows: an electric hoist 2 can lift the material bag in the cage shaft 1, thereby transferring the material bag to the vicinity of the raw material bin 4. A vacuum suction gun 3 is then used to transfer the material from the material bag to the raw material bin 4. A material-gas separator 5 installed on the top of the raw material bin 4 can intercept the solid material, allowing the gas to be discharged by a Roots vacuum pump 7. During the feeding process, the material and dust are sucked in together by the suction gun 3, thereby reducing the dust from escaping into the surrounding work environment, reducing the harm to the health of workers, and reducing the risk of dust explosions.

[0046] The staff then controls the rotary discharge valve 13 to establish communication between the raw material bin 4 and the weighing bin 8, allowing the material in the raw material bin 4 to be transported to the weighing bin 8, where the material is quantitatively weighed. Finally, the screw conveyor 18 conveys the weighed material to the user kettle 17 for reaction processing, thus completing the entire production process.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
