[0002] In many industries such as chemical engineering and new energy, numerous production processes require the addition of powdered raw materials to reaction vessels, which necessitates precise measurement. Often, the amount added each time is small, such as a few kilograms per hour or tens of kilograms per batch. Current technology typically involves manual weighing followed by manual addition through the reaction vessel's inlet or material outlet. Manual addition of powder introduces dust into the workshop during operation, which is often harmful to worker health. Furthermore, opening the reaction vessel's inlet releases volatile gases, which may contain toxic, harmful, flammable, or explosive substances, causing secondary harm to operators' health and polluting the workshop environment.

[0003] Therefore, in order to protect the health of production personnel, it is necessary to reduce manual operations during the powder feeding process and ensure that no dust or other gases escape. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0023] To address the problems in the background art, this utility model provides a system for automatically adding powder to a reaction vessel. The system includes a suction gun station 10, a vacuum hopper 20, and a vacuum feeder 40 connected in sequence. The vacuum hopper 20 is located at the top of the reaction vessel 30. A powder ton bag is placed inside the suction gun station 10. The vacuum feeder 40 is activated to suck the material from the suction gun station 10 into the vacuum hopper 20. The material is intercepted by the vacuum hopper 20 and flows into the reaction vessel 30. Air is drawn into the vacuum feeder 40, filtered, and then discharged. The suction gun station 10 is located on the ground and has a suction gun 11 on one side. The suction gun 11 is equipped with a material-cutting valve and can be locked onto the side of the suction gun station 10. The suction gun 11 transports the powder material to the vacuum hopper 20 through a pipe 51. The vacuum hopper 20 includes a vacuum hopper inlet 21, a filter 25, and a vacuum hopper outlet 22. 1. The suction gun 11 is connected through pipe 1 51. The vacuum hopper outlet 22 is connected to the vacuum feeder 40 through pipe 2 52. The vacuum hopper inlet 21 is positioned lower than the vacuum hopper outlet 22 to ensure that the material is intercepted due to its own gravity. On the other hand, the filter 25 is set between the vacuum hopper inlet 21 and the vacuum hopper outlet 22. After the powder material enters the vacuum hopper 20 through the vacuum hopper inlet 21, it is intercepted by the filter 25 and falls into the collection hopper 24 due to its own gravity. The collection hopper 24 is located at the bottom of the vacuum hopper inlet 21. The collection hopper 24 is connected to the reaction tank 30 through the discharge butterfly valve 23. The upper part of the reaction tank 30 has an integrally formed reaction tank powder inlet 31. The discharge butterfly valve 23 connects the reaction tank powder inlet 31 to the collection hopper 24. After the material reaches the predetermined weight, the discharge butterfly valve 23 opens and the powder falls into the reaction tank 30. After the material is discharged, the discharge butterfly valve 23 closes. The material weighing is achieved using a weighing sensor 32, which is mounted on a support 3. The bottom of the reaction vessel 30 is suspended within the support 3. The weighing sensor 32 measures the total weight of the reaction vessel 30 and the vacuum hopper 20. Alternatively, the weighing can be achieved by weighing the vacuum hopper 20. In this case, a support is installed on the reaction vessel 30 to support and suspend the vacuum hopper 20. The bottom of the vacuum hopper 20 is connected to the reaction vessel 30 via a flexible connection, which does not affect the weighing of the vacuum hopper 20. The material is drawn into the vacuum hopper 20 by a vacuum feeder 40, which includes a dust filter 41 and a vortex blower 42. The vortex blower 42 is connected to the top of the dust filter 41, and the lower part of the dust filter 41 has a vacuum feeder inlet 43. The vacuum feeder inlet 43 is connected to the vacuum hopper outlet 22 via a pipe 52. After the vortex blower 42 starts, it provides negative pressure to the system. The airflow moves along the direction of suction gun 11, pipe 1 51, vacuum hopper 20, pipe 2 52, dust filter 41, and vortex blower 42, and finally the filtered air is discharged into the atmosphere. This system can be automatically controlled by a PLC, and all operating data can be recorded.

[0024] In use, first determine the weight of the material to be added. This weight is also the weight value that the weighing sensor 32 needs to add based on the initial weight. At this time, the discharge butterfly valve 23 is closed. Bagged or barrelled powder is placed in the suction gun station 10. The suction gun 11 is manually placed into the material. The material shut-off valve of the suction gun 11 is opened, and the negative pressure formed in the vortex fan 42 system is started, so that the material is sucked through the suction gun 11 and pipe 51 to the vacuum feeding hopper 20. The filter 25 in the vacuum feeding hopper 20 captures dust. The material falls into the collection hopper 24 below; when the increase value of the weighing sensor 32 reaches the required weight, the vortex blower 42 stops, the discharge butterfly valve 23 opens to feed the material into the reaction tank 30 to complete the quantitative feeding, and the discharge butterfly valve 23 closes; after the powder is intercepted, the intercepting valve of the suction gun 11 closes and no longer sucks material, the gas flows out from the vacuum feeding hopper outlet 22, passes through the second pipe 52 and enters the dust filter 41, the dust filter 41 filters and removes the dust in the gas, and after meeting the emission conditions, it is discharged into the atmosphere through the vortex blower 42. This utility model system has a compact layout, and the pipeline route can be adjusted according to the actual site conditions to adapt to different production conditions; it realizes the operation of powder materials in a fully enclosed system, preventing powder leakage and pollution of the environment and affecting the health of personnel; in places with harsh production environments, it can ensure the safety of the production environment and effectively protect the health of workers.

[0025] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
