Description

Technical Field

[0001] This utility model relates to the chemical industry, and in particular to an automatic powder spraying device. Background Technology

[0002] In existing chemical production, flammable and explosive dust is often involved. In the absence of automatic dust spraying devices, it is necessary to rely on manual addition or simple equipment to transport inert dust. This not only makes it difficult to ensure uniform mixing of inert dust and to fully suppress the combustion and explosion reaction of flammable and explosive dust, but also may lead to untimely or insufficient addition of inert dust due to human operation errors, which greatly increases the probability of dust explosions, fires and other safety accidents, threatening the production site and the personal safety of workers. Utility Model Content

[0003] Therefore, it is necessary to provide an automatic powder spraying device to address the lack of such a device in production sites filled with flammable and explosive dust.

[0004] An automatic powder spraying device includes: a housing assembly having a powder inlet and a separation chamber, the separation chamber being a plurality of such chambers; a stirring assembly disposed on the housing assembly, the stirring assembly having a stirring chamber; a powder spraying assembly disposed on the housing assembly with a portion of the powder spraying assembly passing through the housing assembly, the powder spraying assembly being disposed opposite to the stirring assembly, the powder spraying assembly having a dust collection chamber and a powder spraying channel, the powder inlet, the plurality of separation chambers, the stirring chamber, the dust collection chamber, and the powder spraying channel being sequentially connected; and an electrical control assembly disposed on the housing assembly.

[0005] The aforementioned automatic powder spraying device discloses a core structural component, including the outer shell, stirring assembly, and powder spraying assembly, all made of high-quality materials such as stainless steel. These materials are not only rust-resistant, ensuring the long-term stability and integrity of each component structure and guaranteeing the unobstructed flow of key channels such as the powder inlet, separation chamber, stirring chamber, dust collection chamber, and powder spraying channel, but also easy to clean, facilitating daily cleaning by staff. This also avoids potential contamination from the materials themselves, preventing pollution of the processed inert dust at the source, thereby ensuring that subsequent product quality meets requirements. The device thoroughly mixes the inert dust within the stirring chamber using the stirring assembly. The inert dust output through the powder spraying channel of the powder spraying assembly exhibits excellent explosion-proof properties, effectively suppressing the combustion and explosion reactions of flammable and explosive dust, significantly reducing the probability of safety accidents, and providing reliable protection for the production environment and the personal safety of workers. In addition, the dust collection chamber of the powder spraying component not only collects dust but also weighs inert dust, allowing for real-time monitoring of dust weight. When the inert dust is about to run out, the powder spraying component can transmit a signal to the electronic control component, which then triggers an alarm to remind staff to add dust through the powder inlet in time, preventing production interruptions due to insufficient dust. At the same time, the electronic control component can also work with the powder spraying component to monitor the powder output of the powder spraying channel in real time, allowing staff to make adjustments according to production needs and ensuring the stability and accuracy of the production process.

[0006] In one embodiment, the stirring assembly includes a stirring shell assembly, a stirring power assembly, and a stirring body. The shell assembly has a receiving cavity, and the stirring shell assembly is disposed on the shell assembly and located within the receiving cavity. The stirring shell assembly has the stirring cavity. The stirring power assembly is disposed on the shell assembly and the stirring shell assembly, with a portion of the stirring power assembly located within the stirring cavity. The stirring body is disposed on the stirring power assembly and located within the stirring cavity. By using the stirring shell assembly as the supporting body for the stirring cavity and installing it within the receiving cavity of the shell assembly, not only can the spatial limiting effect of the receiving cavity ensure the stability of its installation position and prevent positional displacement due to vibration during stirring, but the stirring cavity itself also provides an independent and enclosed stirring space for inert dust. Combined with the excellent sealing performance of the entire device, this prevents dust leakage from the stirring cavity during stirring and ensures that the dust is concentrated within the cavity for stirring, laying a spatial foundation for subsequent thorough mixing. The stirring power unit is mounted across both the outer casing and the stirring housing assembly, extending partially into the stirring chamber. This mounting method ensures stability during operation through the double fixation of the outer casing and stirring housing assembly, preventing shaking during power output that could affect the stirring effect. Furthermore, the portion extending into the stirring chamber precisely transmits power to the stirring body, providing a sufficient and continuous power source for its operation. The stirring body is mounted on the stirring power unit and is completely located within the stirring chamber. Driven by the stirring power unit, it achieves efficient rotation within the stirring chamber. Through direct contact with the inert dust, it converts power into stirring force, thoroughly agitating and mixing the inert dust entering the stirring chamber, breaking up dust agglomerations and ensuring uniform distribution of inert dust particles.

[0007] In one embodiment, the stirring shell assembly includes a transition shell, a first stirring shell, and a second stirring shell. The first stirring shell is disposed on the outer shell assembly, the transition shell is disposed at one end of the first stirring shell, and the second stirring shell is disposed on the first stirring shell and located at the end away from the transition shell. A portion of the stirring power assembly is disposed on the transition shell. The transition shell, the first stirring shell, and the second stirring shell cooperate to form the stirring chamber. By using the first stirring shell as the main support structure of the stirring shell assembly and directly mounting it on the outer shell assembly, on the one hand, the stability of the outer shell assembly provides a reliable installation foundation for the entire stirring shell assembly, ensuring the positional accuracy of the subsequent installation of the transition shell and the second stirring shell, and avoiding deformation or displacement of the stirring chamber due to unstable foundation, thereby ensuring the stability of the stirring space for inert dust within the chamber. On the other hand, the first stirring shell is the main component of the stirring chamber, and its internal space, together with the internal spaces of the transition shell and the second stirring shell, constitutes a complete stirring chamber, providing a sufficient and continuous stirring area for the inert dust, ensuring that the dust can flow fully within the chamber and contact the stirring body, creating conditions for subsequent uniform mixing. The transition shell is located at one end of the first stirring shell. In addition to forming a closed stirring chamber with the first and second stirring shells to prevent dust leakage, it also plays a key role in connecting the stirring power component. Since part of the stirring power component is located on the transition shell, the transition shell can provide the stirring power component with precise installation positioning and stable support, avoiding the shaking of the stirring power component due to unstable installation during operation, and ensuring that it can stably and accurately transmit power to the stirring body.

[0008] In one embodiment, the stirring chamber includes a connecting port, a transition chamber, a first stirring chamber, and a second stirring chamber. The transition shell is provided with the connecting port and the transition chamber. There are multiple connecting ports, each communicating with one of the multiple separation chambers. The first stirring shell is provided with the first stirring chamber, and the second stirring shell is provided with the second stirring chamber. The multiple connecting ports, the transition chamber, the first stirring chamber, the second stirring chamber, the dust collection chamber, and the powder spraying channel are sequentially connected. The multiple connecting ports on the transition shell serve as the primary channels for inert dust to enter the stirring chamber. Because they are connected to the multiple separation chambers, it ensures that the inert dust, after preliminary treatment in the separation chambers, can enter the stirring chamber synchronously and evenly through the corresponding connecting ports, avoiding dust accumulation or uneven transport problems caused by a single channel. The transition chamber allows the dust to enter the next stirring stage in a more stable and uniform state. The first stirring chamber within the first stirring shell serves as the core stirring area, where the stirring body performs its main stirring operations. Inert dust entering the first stirring chamber from the transition chamber is thoroughly agitated and mixed under the high-speed rotation of the stirring body, effectively breaking up dust particle agglomeration and resulting in a more uniform dust particle distribution. The second stirring chamber within the second stirring shell then undertakes secondary stirring and transitional transfer of the dust. After initial stirring in the first stirring chamber, the dust enters the second stirring chamber and undergoes further stirring and transport under the influence of the stirring body extending to this area. Simultaneously, the second stirring chamber is directly connected to the dust collection chamber, and its structural design guides the uniformly stirred dust smoothly and orderly into the dust collection chamber, preventing dust accumulation or splashing due to sudden path changes during transport, thus ensuring the smooth operation of subsequent weighing and powder spraying processes.

[0009] In one embodiment, the stirring body includes an upper stirring element and a lower stirring element, both of which are disposed on the stirring power assembly. The stirring chamber includes a transition chamber, a first stirring chamber, and a second stirring chamber. A portion of the upper stirring element is located in the transition chamber, the remaining portion of the upper stirring element is located in the first stirring chamber, and the lower stirring element is located in the second stirring chamber. By splitting the stirring body into an upper and lower stirring element, and precisely arranging them according to the functional differences of each area of ​​the stirring chamber, they work together under the drive of the stirring power assembly, significantly improving the uniformity of inert dust mixing. The upper stirring element is partially located in the transition chamber, and the remaining portion is in the first stirring chamber. In the transition chamber, it can initially agitate the dust entering from the connection port, assisting in its rapid fusion and preventing accumulation. The portion entering the first stirring chamber, as the core stirring structure, can powerfully break up dust agglomerations and fully mix the dust, laying the foundation for subsequent processing. The lower agitator is located in the second agitation chamber. It performs secondary agitation on the dust after it has been processed in the first agitation chamber, eliminating dead zones and further improving uniformity. At the same time, it can guide the dust to flow smoothly into the dust collection chamber, avoiding accumulation during transportation, ensuring smooth connection between agitation and subsequent powder spraying, and ensuring that the output dust meets the requirements for explosion-proof and precise powder spraying.

[0010] In one embodiment, the powder spraying assembly includes a dust collection housing, a powder spraying component body, and an output pipe. The dust collection housing is mounted on the outer shell assembly. One end of the powder spraying component body is mounted on the dust collection housing, and the other end of the powder spraying component body is connected to the output pipe via a pipe. The output pipe passes through the outer shell assembly. The dust collection housing has a dust collection chamber, and the output pipe has a powder spraying channel. By mounting the dust collection housing on the outer shell assembly, the stability of the outer shell assembly is utilized to ensure its own positional stability. The dust collection chamber accurately receives the inert dust transported from the second mixing chamber, achieving centralized dust collection. Simultaneously, the dust collection chamber provides a stable space for dust weighing, facilitating real-time monitoring of dust levels and laying the foundation for subsequent alarm reminders for powder replenishment and control of powder output. One end of the powder spraying component body is connected to the dust collection housing, and the other end is connected to the output pipe via a pipe, serving as a transition and transfer mechanism. Air pressure is used to smoothly transport the dust from the dust collection chamber to the output pipe, preventing dust accumulation and blockage during transport and ensuring smooth dust flow. The output pipe passes through the outer shell assembly, and its internal powder spraying channel is the final dust output channel. This not only achieves precise dust delivery to the outside of the device to meet the powder spraying needs in production, but also ensures the airtightness of the powder spraying process and reduces dust leakage due to the design of passing through the outer shell assembly. At the same time, the structural design of the powder spraying channel can be combined with the electronic control components to monitor the powder output in real time, ensuring that the powder output is accurate and controllable, helping the inert dust to fully exert its explosion-proof function and improving production safety and stability.

[0011] In one embodiment, the outer shell assembly includes a lower shell assembly, an upper shell assembly, and a feeding shell. The upper shell assembly is disposed on the lower shell assembly, and the feeding shell is disposed on the upper shell assembly. The lower shell assembly and the upper shell assembly cooperate to form a receiving cavity. The stirring assembly is located in the receiving cavity, with a portion of the stirring assembly disposed on the upper shell assembly and the remaining portion disposed on the lower shell assembly and passing through the upper shell assembly. The powder spraying assembly is disposed on the lower shell assembly, with a portion of the powder spraying assembly passing through the lower shell assembly. The electrical control assembly is disposed on the lower shell assembly and the upper shell assembly. By using the lower shell assembly as the bottom foundation of the device, a stable mounting platform is provided for the powder spraying assembly. The powder spraying assembly is disposed on it and partially passes through the lower shell assembly, ensuring that the position of the powder spraying assembly is fixed, avoiding shaking during operation that affects the powder spraying accuracy, and allowing the powder spraying channel of the powder spraying assembly to extend smoothly to the outside of the device to meet the dust output requirements during production. The lower shell assembly and the upper shell assembly jointly support the electrical control assembly, providing reliable support for the electrical control system, ensuring its stable operation and control of various components. The upper shell assembly is mounted on the lower shell assembly, and the two together form a receiving cavity that creates a closed and safe working space for the mixing assembly. This ensures that the mixing body of the assembly can operate stably within the receiving cavity, achieving thorough mixing of inert dust while preventing dust leakage during the mixing process and avoiding pollution of the surrounding environment. The feed housing is located on the upper shell assembly, serving as the carrier for the powder inlet and providing a convenient channel for inert dust to enter the device. Its position is designed for easy addition of dust by personnel and can be precisely connected to the subsequent separation chamber, ensuring that the dust smoothly enters the separation stage.

[0012] In one embodiment, the feeding housing includes a mounting housing and a separating housing. The mounting housing is disposed on the upper shell assembly, and multiple separating housings are disposed on the mounting housing. Each mounting housing has a powder inlet, and each separating housing has a separating chamber. By placing the mounting housing on the upper shell assembly, the stability of the upper shell assembly is utilized to ensure stable installation, and the powder inlet provides a convenient channel for workers to add inert dust, guiding the dust accurately into the device and avoiding waste and pollution caused by dust spillage during addition. Multiple separating housings are mounted on the mounting housing, and each separating housing has a separating chamber, which can perform preliminary separation treatment on the inert dust entering from the powder inlet, improving the purity and dispersion of the dust. At the same time, the multiple separating chambers can be connected one-to-one with multiple connection ports of the mixing chamber, ensuring that the separated dust can be uniformly and synchronously transported to the mixing chamber, laying the foundation for subsequent thorough mixing.

[0013] In one embodiment, an opening and closing component is also included. This component is disposed on the stirring assembly, with a portion located within the dust collection chamber. The opening and closing component controls the connection or blockage between the dust collection chamber and the stirring chamber. By positioning the opening and closing component on the stirring assembly and partially within the dust collection chamber, the device can leverage the stability of the stirring assembly to ensure precise installation while also efficiently acting on the connection channel between the two chambers at close range. When the device needs to supply stirred, inert dust to the dust collection chamber, the opening and closing component can control the channel to open, allowing the uniformly mixed dust in the stirring chamber to flow smoothly into the dust collection chamber, ensuring the raw material supply for subsequent weighing and powder spraying stages. When the dust in the dust collection chamber reaches the required amount or the supply needs to be paused, the opening and closing component can quickly block the channel, preventing excessive dust from entering and affecting weighing accuracy, or preventing dust accumulation in the dust collection chamber due to continued powder supply from the stirring chamber.

[0014] In one embodiment, the opening and closing assembly includes a first fixed shell, a second fixed shell, an opening and closing power component, and a cover. The first fixed shell is disposed on the stirring assembly and away from the outlet end of the stirring chamber. The second fixed shell is disposed on the stirring assembly and close to the outlet end of the stirring chamber. The fixed end of the opening and closing power component is disposed on the first fixed shell, and the output end of the opening and closing power component is disposed on the second fixed shell. The cover is disposed on the second fixed shell, and the cover can open or close the stirring chamber to control the connection or blockage between the dust collection chamber and the stirring chamber. By mounting the first fixed shell on the stirring assembly away from the outlet end of the stirring chamber, a stable support is provided for the fixed end of the opening and closing power component, preventing the power component from shaking during operation and ensuring stable power output. The second fixed shell is located on the stirring assembly near the outlet end of the stirring chamber, receiving the output end of the power component and simultaneously supporting the cover, ensuring that the cover is accurately aligned with the outlet of the stirring chamber and ensuring accurate on / off action. The opening and closing power component is connected to the two fixed shells at both ends, outputting driving force to drive the second fixed shell and the cover to move, providing power for on / off action. The cover is installed on the second fixed shell and can open or close the outlet of the mixing chamber. It can be opened when powder needs to be conveyed to connect the two chambers; it can be closed when the dust reaches the standard or when it needs to be paused to ensure the weighing accuracy of the dust collection chamber and avoid dust leakage or accumulation.

[0015] In one embodiment, a plurality of pulley assemblies are also included, arranged circumferentially around the bottom of the housing assembly. By evenly distributing the pulley assemblies on the bottom of the housing assembly, the weight of the entire device can be stably supported, preventing damage caused by excessive force on a single point and ensuring the stability of the device during placement. When the device position needs to be adjusted, workers do not need to carry it laboriously; the rolling characteristics of the pulley assemblies allow the device to be easily moved within the production area, quickly adjusting it to a suitable working position to adapt to the layout requirements of different production scenarios, reducing manpower consumption and adjustment time.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] The automatic powder spraying device of this utility model is described below with reference to the accompanying drawings.

[0037] Example

[0038] like Figures 1 to 11 As shown, this embodiment discloses an automatic powder spraying device, including: a housing assembly 1, which has a powder inlet 101 and a separation chamber 102, and the number of separation chambers 102 is multiple; a stirring assembly 2, which is disposed on the housing assembly 1 and has a stirring chamber 201; a powder spraying assembly 3, which is disposed on the housing assembly 1 and a portion of the powder spraying assembly 3 passes through the housing assembly 1, and the powder spraying assembly 3 is disposed opposite to the stirring assembly 2, and the powder spraying assembly 3 has a dust collection chamber 301 and a powder spraying channel 302, and the powder inlet 101, multiple separation chambers 102, stirring chamber 201, dust collection chamber 301 and powder spraying channel 302 are sequentially connected; and an electrical control assembly 4, which is disposed on the housing assembly 1.

[0039] This application discloses an automatic powder spraying device. The core structural components of the device, such as the outer shell assembly 1, stirring assembly 2, and powder spraying assembly 3, are all made of high-quality materials such as stainless steel. These materials are not only rust-resistant, but also maintain the stability and integrity of each component structure for a long time, ensuring the unobstructed flow of key channels such as the powder inlet 101, separation chamber 102, stirring chamber 201, dust collection chamber 301, and powder spraying channel 302. They are also easy to clean, facilitating daily cleaning by staff, while avoiding potential contamination from the materials themselves. This prevents contamination of the processed inert dust from the source, thereby ensuring that the quality of subsequent related products meets requirements. The device, through the stirring assembly 2, thoroughly mixes the inert dust in the stirring chamber 201. The inert dust output through the powder spraying channel 302 of the powder spraying assembly 3 exhibits excellent explosion-proof properties, effectively suppressing the combustion and explosion reactions of flammable and explosive dust, significantly reducing the probability of safety accidents, and providing reliable protection for the production environment and the personal safety of staff. In addition, the dust collection chamber 301 of the powder spraying component 3 not only has the function of dust collection, but also weighs the inert dust and monitors the dust weight in real time. When the inert dust is about to run out, the powder spraying component 3 can transmit a signal to the electronic control component 4, which will trigger an alarm function to remind the staff to add dust through the powder inlet 101 in time to avoid production interruption due to insufficient dust. At the same time, the electronic control component 4 can also work with the powder spraying component 3 to monitor the powder output of the powder spraying channel 302 in real time, so that the staff can make adjustments according to production needs and ensure the stability and accuracy of the production process.

[0040] like Figure 4 , Figure 6 , Figure 7 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the stirring assembly 2 includes a stirring shell assembly 21, a stirring power assembly 22, and a stirring body 23; the outer shell assembly 1 is provided with a receiving cavity 103; the stirring shell assembly 21 is disposed on the outer shell assembly 1 and located in the receiving cavity 103; the stirring shell assembly 21 is provided with a stirring cavity 201; the stirring power assembly 22 is disposed on the outer shell assembly 1 and the stirring shell assembly 21; a portion of the stirring power assembly 22 is located in the stirring cavity 201; and the stirring body 23 is disposed on the stirring power assembly 22 and located in the stirring cavity 201. By using the stirring shell assembly 21 as the main support for the stirring chamber 201, and installing it within the receiving cavity 103 of the outer shell assembly 1, the stability of its installation position is ensured by the spatial limiting effect of the receiving cavity 103, preventing positional displacement due to vibration during stirring. Furthermore, the stirring chamber 201 provides an independent and enclosed stirring space for inert dust. Combined with the overall excellent sealing performance of the device, dust leakage from the stirring chamber 201 during stirring is prevented. Simultaneously, it ensures that the dust is concentrated within the chamber for stirring, laying a spatial foundation for thorough mixing. The stirring power assembly 22 is mounted across the outer shell assembly 1 and the stirring shell assembly 21, partially extending into the stirring chamber 201. This installation method ensures the stability of its operation through the double fixation of the outer shell assembly 1 and the stirring shell assembly 21, preventing shaking during power output that could affect the stirring effect. Simultaneously, the portion extending into the stirring chamber 201 precisely transmits power to the stirring body 23, providing a sufficient and continuous power source for the operation of the stirring body 23. The stirring body 23 is mounted on the stirring power assembly 22 and is completely located inside the stirring chamber 201. Driven by the stirring power assembly 22, it can achieve efficient rotation inside the stirring chamber 201. Through direct contact with the inert dust, the power is converted into stirring force, which fully stirs and mixes the inert dust entering the stirring chamber 201, breaks the dust agglomeration phenomenon, and ensures that the inert dust particles are evenly distributed.

[0041] like Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines that: the stirring shell assembly 21 includes a transition shell 211, a first stirring shell 212 and a second stirring shell 213. The first stirring shell 212 is disposed on the outer shell assembly 1, the transition shell 211 is disposed on one end of the first stirring shell 212, the second stirring shell 213 is disposed on the first stirring shell 212 and located at the end away from the transition shell 211, a portion of the stirring power assembly 22 is disposed on the transition shell 211, and the transition shell 211, the first stirring shell 212 and the second stirring shell 213 cooperate to form a stirring chamber 201. By using the first stirring shell 212 as the main support structure of the stirring shell assembly 21, which is directly mounted on the outer shell assembly 1, the stability of the outer shell assembly 1 provides a reliable installation foundation for the entire stirring shell assembly 21, ensuring the positional accuracy of the subsequent installation of the transition shell 211 and the second stirring shell 213, and preventing deformation or displacement of the stirring chamber 201 due to unstable foundation, thereby ensuring the stability of the stirring space for inert dust within the chamber. On the other hand, the first stirring shell 212 is a major component of the stirring chamber 201, and its internal space, together with the internal spaces of the transition shell 211 and the second stirring shell 213, constitutes a complete stirring chamber 201, providing a sufficient and continuous stirring area for the inert dust, ensuring that the dust can flow fully within the chamber and contact the stirring body 23, creating conditions for subsequent uniform mixing. The transition housing 211 is located at one end of the first stirring housing 212. In addition to forming a closed stirring chamber 201 together with the first stirring housing 212 and the second stirring housing 213 to prevent dust leakage, it also plays a key role in connecting the stirring power assembly 22. Since part of the stirring power assembly 22 is located on the transition housing 211, the transition housing 211 can provide the stirring power assembly 22 with precise installation positioning and stable support, so as to prevent the stirring power assembly 22 from shaking due to unstable installation during operation, and ensure that it can stably and accurately transmit power to the stirring body 23.

[0042] like Figure 6 , Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines that: the stirring chamber 201 includes a connection port 2011, a transition chamber 2012, a first stirring chamber 2013, and a second stirring chamber 2014; the transition shell 211 is provided with the connection port 2011 and the transition chamber 2012; the number of connection ports 2011 is multiple; the multiple connection ports 2011 are connected to the multiple separation chambers 102 one by one; the first stirring shell 212 is provided with the first stirring chamber 2013; the second stirring shell 213 is provided with the second stirring chamber 2014; the multiple connection ports 2011, the transition chamber 2012, the first stirring chamber 2013, the second stirring chamber 2014, the dust collection chamber 301, and the powder spraying channel 302 are connected in sequence. Multiple connection ports 2011 on the transition shell 211 serve as the primary channels for inert dust to enter the mixing chamber 201. Because they are connected to multiple separation chambers 102, it ensures that the inert dust, after preliminary treatment by the separation chambers 102, can enter the mixing chamber 201 synchronously and evenly through the corresponding connection ports 2011, avoiding dust accumulation or uneven transport caused by a single channel. The transition chamber 2012 allows dust to enter the next mixing stage in a more stable and uniform state. The first mixing chamber 2013 within the first mixing shell 212, as the core mixing area of ​​the mixing chamber 201, is where the mixing body 23 performs its main mixing work. The inert dust entering the first mixing chamber 2013 from the transition chamber 2012 is fully agitated and mixed under the high-speed operation of the mixing body 23, effectively breaking up the agglomeration of dust particles and making the dust particle distribution more uniform. The second stirring chamber 2014 within the second stirring housing 213 serves as a secondary stirring and transitional transfer point for the dust. After initial stirring in the first stirring chamber 2013, the dust enters the second stirring chamber 2014 and undergoes further stirring and transport under the influence of the extended portion of the stirring body 23. Simultaneously, the second stirring chamber 2014 is directly connected to the dust collection chamber 301. Its structural design guides the uniformly stirred dust smoothly and orderly into the dust collection chamber 301, preventing dust accumulation or splashing due to sudden path changes during transport, thus ensuring the smooth operation of subsequent weighing and powder spraying processes.

[0043] like Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the stirring body 23 includes an upper stirring element 231 and a lower stirring element 232, both of which are disposed on the stirring power assembly 22; the stirring chamber 201 includes a transition chamber 2012, a first stirring chamber 2013, and a second stirring chamber 2014; a portion of the upper stirring element 231 is located in the transition chamber 2012, the remaining portion of the upper stirring element 231 is located in the first stirring chamber 2013, and the lower stirring element 232 is located in the second stirring chamber 2014. By dividing the stirring body 23 into the upper stirring element 231 and the lower stirring element 232, and precisely arranging them according to the functional differences of each region of the stirring chamber 201, they work together under the drive of the stirring power assembly 22, significantly improving the uniformity of inert dust mixing. The upper agitator 231 is partially located in the transition chamber 2012, with the remainder in the first agitator 2013. In the transition chamber 2012, it provides initial agitation for the dust entering from the connection port 2011, aiding in rapid mixing and preventing accumulation. The portion entering the first agitator 2013, as the core agitation structure, powerfully breaks up dust agglomerates, thoroughly mixing the dust and laying the foundation for subsequent processing. The lower agitator 232 is located in the second agitator 2014, providing secondary agitation for the dust processed in the first agitator 2013, eliminating dead zones and further improving uniformity. Simultaneously, it guides the dust smoothly towards the dust collection chamber 301, preventing accumulation during transport and ensuring smooth connection between agitation and subsequent powder spraying, guaranteeing that the output dust meets explosion-proof and precise powder spraying requirements.
