Abstract
Description
Technical Field
[0001] This application relates to the field of battery processing equipment technology, and in particular to a stirring device. Background Technology
[0002] In the battery manufacturing process, the production process of cathode and anode powders is involved. In the pre-production process, the cathode and anode powders need to be put into the feeding container. During the feeding process, some of the powders can easily fly into the air, which may have an impact on the occupational health and safety of employees.
[0003] In related technologies, dust collectors are used to suck up the flying powder. However, this requires manual disassembly and cleaning of the dust collectors regularly. Cleaning the dust collectors also causes powder to fly around, which can affect the occupational health and safety of employees. At the same time, the large amount of powder sucked up by the dust collectors results in powder waste. Utility Model Content
[0004] In view of the above problems, this application provides a mixing device to solve the problem of powder flying during cleaning, which causes occupational health and safety impacts on employees and also causes powder waste.
[0005] This application provides a mixing device, including a feeding container, a suction pipe, a dust suction pipe, and a device body; the feeding container has a feeding port and a discharging port, the feeding port being configured to feed powder; the inlet of the suction pipe is connected to the discharging port, and a negative pressure is configured to be formed inside the suction pipe; the inlet of the dust suction pipe is connected to the feeding port, and the outlet of the dust suction pipe is connected to the suction pipe, under the negative pressure of the suction pipe, the powder in the feeding container is sucked away from the discharging port, and the powder in the feeding container is sucked into the suction pipe through the dust suction pipe; the device body includes a powder storage tank, and the powder storage tank is connected to the outlet of the suction pipe.
[0006] In the technical solution of this application embodiment, the dust collection pipe is directly connected to the material suction pipe, so that the inlet of the dust collection pipe is connected to the feeding port of the feeding container, and the outlet of the dust collection pipe is connected to the material suction pipe. When some powder is airborne during the powder feeding process, the airborne powder can be directly sucked into the material suction pipe under negative pressure, and finally sucked into the powder storage tank for storage and use. Therefore, the airborne powder can also be sucked away and utilized, achieving the goal of turning waste into treasure; at the same time, the use of a dust collector is eliminated, and there is no need for manual disassembly and cleaning of the dust collector periodically. Therefore, this solution solves the problem of occupational health and safety impacts on employees caused by airborne powder during cleaning, as well as the problem of powder waste.
[0007] In some embodiments, the suction pipe includes a main pipe and branch pipes; the inlet of the main pipe is connected to the outlet, and the outlet of the main pipe is connected to the powder storage tank; the branch pipe is connected between the inlet and outlet of the main pipe, the inlet of the branch pipe is connected to the outlet of the dust collection pipe, and the outlet of the branch pipe is connected to the main pipe. This design allows for easy connection between the branch pipe and the dust collection pipe, enabling the branch pipe to connect with the main pipe and the dust collection pipe. When negative pressure is generated in the main pipe, negative pressure can also be generated in the branch pipe and the dust collection pipe. Under this negative pressure, the raised powder can be directly sucked into the branch pipe through the dust collection pipe, and then sequentially sucked into the powder storage tank through the branch pipe and the main pipe for storage and use.
[0008] In some embodiments, the main pipeline includes a first main pipeline and a second main pipeline; a branch pipeline is connected to the first main pipeline, the outlet of the first main pipeline is connected to the powder storage tank, and an air inlet is provided at the end of the first main pipeline away from the outlet; the inlet of the second main pipeline is connected to the discharge port, and the outlet of the second main pipeline is connected to the first main pipeline. This design allows the branch pipeline and the second main pipeline to be connected in parallel to the first main pipeline. When a negative pressure is generated in the first main pipeline, the powder in the feeding container can be sucked into the first main pipeline from the discharge port through the second main pipeline. Simultaneously, the powder thrown up in the feeding container can be sucked into the first main pipeline through the branch pipeline and the dust extraction pipeline. Finally, the powder is collected and transported to the powder storage tank for storage and use through the first main pipeline, thus simultaneously achieving the functions of material suction and dust extraction.
[0009] In some embodiments, a magnetic suction structure is provided on the branch pipe, which is configured to attract impurities in the powder flowing through the branch pipe. This design addresses the issue that when powder is added to the feeding container, the bag containing the powder is typically added along with it. This bag may contain impurities (such as iron, cobalt, nickel, manganese, etc.), which are easily drawn into the dust collection duct as the powder is dispersed. Therefore, by providing a magnetic suction structure on the branch pipe, impurities in the powder can be attracted away as it flows from the dust collection duct to the branch pipe, thereby improving the purity of the powder.
[0010] In some embodiments, the magnetic structure is a magnetic rod, which is inserted into the branch pipe. This design allows the magnetic rod to be directly inserted into the branch pipe during installation, facilitating the installation of the magnetic structure.
[0011] In some embodiments, the magnetic structure is detachably installed on the branch pipe. This design allows the magnetic structure to be detachably installed on the branch pipe. When a large amount of impurities are attracted to the magnetic structure, it can be removed from the branch pipe to clean the impurities before being reinstalled on the branch pipe, thus facilitating the cleaning of the magnetic structure.
[0012] In some embodiments, a filter is also provided on the branch pipe, which is configured to filter impurities in the powder flowing through the branch pipe. This design addresses the issue that the material bag may contain not only iron impurities but also other impurities (such as dirt, fragments from a broken material bag, etc.). These impurities are easily drawn into the dust collection duct along with the powder. Therefore, by installing a filter on the branch pipe, impurities in the powder can be filtered out as it flows from the dust collection duct to the branch pipe, thereby further improving the purity of the powder.
[0013] In some embodiments, the magnetic suction structure is located between the filter and the inlet of the branch pipe. This design allows the powder to be magnetically attracted by the magnetic suction structure before being filtered by the filter. This allows some impurities to be adsorbed onto the magnetic suction structure first, reducing the amount of impurities flowing to the filter and preventing impurities from clogging the filter, thereby reducing the frequency of filter cleaning.
[0014] In some embodiments, the filter is detachably installed on the branch pipe. This design allows the filter to be detachably installed on the branch pipe. When there are many impurities filtered by the filter, the filter can be removed from the branch pipe to clean the impurities before reinstalling it on the branch pipe, or a new filter can be directly replaced, thus facilitating the cleaning and replacement of the filter.
[0015] In some embodiments, the feeding container is equipped with a liftable bag-pressing structure, which is configured to press or release the bag containing powder in the feeding container. With this design, when the bag containing powder is fed into the feeding container, because the bag is relatively heavy, the suction pipe will not suck the powder away all at once. Therefore, to prevent the bag from shifting as its weight gradually decreases, a bag-pressing structure is used to press the bag down.
[0016] In some embodiments, the feeding container is further provided with an overflow port located between the feeding port and the discharge port; the mixing equipment also includes an overflow pipe, the inlet of which is connected to the overflow port, and the outlet of which is connected to the suction pipe. Under the negative pressure of the suction pipe, the powder in the feeding container is sucked from the overflow port into the overflow pipe. With this design, when the bag containing powder is put into the feeding container, the bag is compressed using a compression structure. During the compression process, the middle of the bag is prone to tearing and the powder overflows. The overflowing powder can be sucked from the overflow port into the overflow pipe under the negative pressure of the suction pipe, and then sucked into the suction pipe, thereby improving the suction efficiency of the suction pipe.

[0032] In the battery manufacturing process, the production process of cathode and anode powders is involved. In the pre-production process, the cathode and anode powders need to be put into the feeding container. During the feeding process, some of the powders can easily fly into the air, which may have an impact on the occupational health and safety of employees.
[0033] In related technologies, dust collectors are used to suck up the flying powder. However, this requires manual disassembly and cleaning of the dust collectors regularly. Cleaning the dust collectors also causes powder to fly around, which can affect the occupational health and safety of employees. At the same time, the large amount of powder sucked up by the dust collectors results in powder waste.
[0034] To address the aforementioned problems, this application proposes a mixing device 100, aiming to solve the issues of powder flying during cleaning, which poses occupational health and safety risks to employees and results in powder waste. A detailed description is provided below with reference to the accompanying drawings and embodiments.
[0035] Please see Figures 1 to 3 In one embodiment of this application, the mixing device 100 includes a feeding container 10, a suction pipe 20, a dust suction pipe 30, and a device body. The feeding container 10 is provided with a feeding port 11 and a discharge port 12. The feeding port 11 is configured to feed powder. The inlet of the suction pipe 20 is connected to the discharge port 12, and the suction pipe 20 is configured to form a negative pressure. The inlet of the dust suction pipe 30 is connected to the feeding port 11, and the outlet of the dust suction pipe 30 is connected to the suction pipe 20. Under the negative pressure of the suction pipe 20, the powder in the feeding container 10 is sucked away from the discharge port 12, and the powder in the feeding container 10 is sucked into the suction pipe 20 through the dust suction pipe 30. The device body includes a powder storage tank, which is connected to the outlet of the suction pipe 20.
[0036] The feeding container 10 is a container used to hold powder. Specifically, bagged or barrelled powder can be fed into the feeding container 10 manually or mechanically. The feeding container 10 can have a hollow internal cylindrical or conical shape. The feeding container 10 can be installed and fixed using a support frame. Optionally, the worker feeds a bag containing powder into the feeding container 10 through the feeding port 11. At this time, the bag has an opening, and the powder in the bag can flow from the opening to the discharge port 12 of the feeding container 10. Then, under the negative pressure of the suction pipe 20, the powder in the feeding container 10 is sucked away from the discharge port 12.
[0037] The suction pipe 20 is a pipe used to transport the powder in the feeding container 10 to the powder storage tank. The outlet of the suction pipe 20 is connected to the powder storage tank. Specifically, a fan can be installed in the powder storage tank or in the suction pipe 20 so that the rotation of the fan creates a negative pressure in the suction pipe 20. Under the negative pressure of the suction pipe 20, the powder in the feeding container 10 is sucked away from the outlet 12 to the powder storage tank. The powder raised in the feeding container 10 is also sucked into the suction pipe 20 through the dust suction pipe 30 and finally enters the powder storage tank through the suction pipe 20.
[0038] The suction pipe 30 is a transfer pipe used to suck up the powder flying in the feeding container 10 under negative pressure and transfer it to the suction pipe 20. The inlet end of the suction pipe 30 can be connected to the side wall of the feeding container 10, or it can extend directly into the feeding container 10, as long as the inlet of the suction pipe 30 is connected to the feeding port 11 of the feeding container 10. The outlet end of the suction pipe 30 can be connected to the side wall of the suction pipe 20, or it can extend directly into the suction pipe 20, as long as the outlet of the suction pipe 30 is connected to the suction pipe 20.
[0039] Since the feeding port 11 of the feeding container 10 is usually located in the upper part of the feeding container 10, the staff will put a whole bag of powder into the feeding container 10 through the feeding port 11. When the powder comes into contact with the inner wall of the feeding container 10, it will collide with the inner wall of the feeding container 10. Since the powder is relatively light, some of the powder will fly up to the upper part of the feeding container 10, thus producing "flying powder".
[0040] The equipment body refers to the equipment used for storing and processing powder materials. Specifically, it uses a powder storage tank to store the powder materials and a stirring mechanism to stir and process the powder materials.
[0041] In practical applications, the feeding port 11 can be located at the top of the feeding container 10 or at the side of the feeding container 10. Of course, in order to allow the feeding container 10 to hold larger bags, the feeding port 11 can be located at the top of the feeding container 10 to prevent powder from overflowing from the feeding port 11.
[0042] Furthermore, the discharge port 12 can be located at the bottom of the feeding container 10 or at the side of the feeding container 10. Of course, in order to facilitate the flow of powder from the discharge port 12 to the suction pipe 20, the discharge port 12 can be located at the bottom of the feeding container 10.
[0043] Optionally, the suction pipe 20 and the dust suction pipe 30 can be made of food-grade SUS304 stainless steel seamless pipe fittings, which are oil-free and dust-free, and will not introduce metallic and non-metallic impurities, thereby reducing the impact of metallic and non-metallic impurities on the purity of the powder.
[0044] In summary, the technical solution of this application directly connects the dust suction pipe 30 to the material suction pipe 20, so that the inlet of the dust suction pipe 30 is connected to the feeding port 11 of the feeding container 10, and the outlet of the dust suction pipe 30 is connected to the material suction pipe 20. When some powder is airborne during the powder feeding process, the airborne powder can be directly sucked into the material suction pipe 20 under the negative pressure of the material suction pipe 20, and finally sucked into the powder storage tank for storage and use. Therefore, the airborne powder can also be sucked away and utilized by the material suction pipe 20, achieving the goal of turning waste into treasure; at the same time, the use of a dust collector is eliminated, and there is no need for manual disassembly and cleaning of the dust collector periodically. Therefore, this solution solves the problem of powder flying during cleaning causing occupational health and safety impacts on employees, as well as the problem of powder waste.
[0045] It should be noted that the existing technology uses a dust collector to remove airborne powder, which removes a large amount of powder, resulting in approximately 3 tons of waste powder per month. Manual disassembly and cleaning requires 1 hour for every 2 people; with 12 lines, cleaning twice a month would consume 48 hours of labor, thus consuming a significant amount of time. Furthermore, the airborne powder during cleaning poses a significant occupational health and safety hazard to employees. Therefore, the mixing equipment 100 proposed in this solution not only utilizes the removed powder, turning waste into treasure, but also eliminates the need for regular manual dust collector cleaning, effectively reducing the occupational health and safety impact on employees.
[0046] Please see Figure 1 In one embodiment of this application, the suction pipe 20 includes a main pipe 21 and a branch pipe 22; the inlet of the main pipe 21 is connected to the outlet 12, and the outlet of the main pipe 21 is connected to the powder storage tank; the branch pipe 22 is connected between the inlet and outlet of the main pipe 21, the inlet of the branch pipe 22 is connected to the outlet of the dust suction pipe 30, and the outlet of the branch pipe 22 is connected to the main pipe 21.
[0047] The main pipeline 21 refers to the pipeline used to directly connect the discharge port 12 of the feeding container 10 and the powder storage tank, and to transport the powder in the feeding container 10 from the discharge port 12 to the powder storage tank under negative pressure. The main pipeline 21 can be a single straight pipe or at least two interconnected pipes.
[0048] Branch pipe 22 is a transfer pipe used to connect dust collection pipe 30 and main pipe 21. Under negative pressure, the powder sucked out of dust collection pipe 30 is drawn into branch pipe 22 and then transported to main pipe 21, and finally transported to powder storage tank through main pipe 21. Branch pipe 22 can be a straight pipe or at least two interconnected pipes.
[0049] This design allows the branch pipe 22 to be easily connected to the dust collection pipe 30, enabling the branch pipe 22 to connect the main pipe 21 and the dust collection pipe 30. When a negative pressure is generated in the main pipe 21, a negative pressure can also be generated in the branch pipe 22 and the dust collection pipe 30. Under the action of negative pressure, the raised powder can be directly sucked into the branch pipe 22 through the dust collection pipe 30, and then sequentially sucked into the powder storage tank through the branch pipe 22 and the main pipe 21 for storage and use.
[0050] Please see Figure 1 In one embodiment of this application, the main pipeline 21 includes a first main pipeline 211 and a second main pipeline 212; a branch pipeline 22 is connected to the first main pipeline 211, the outlet of the first main pipeline is connected to the powder storage tank, and an air inlet 211a is provided at the end of the first main pipeline 211 away from the outlet; the inlet of the second main pipeline 212 is connected to the discharge port 12, and the outlet of the second main pipeline 212 is connected to the first main pipeline 211.
[0051] The first main pipe 211 is a pipe used to connect the powder storage tank and is used to set the air inlet 211a so that when negative pressure is generated in the first main pipe 211, the suction pipe 20, the dust suction pipe 30 and the feeding container 10 will not be evacuated into a vacuum state, thus improving the safety of use.
[0052] The second main pipe 212 is a pipe used to connect the discharge port 12 of the feeding container 10 and the first main pipe 211. Under negative pressure, the powder in the feeding container 10 is sucked from the discharge port 12 into the second main pipe 212, then from the second main pipe 212 into the first main pipe 211, and finally transported from the first main pipe 211 to the powder storage tank.
[0053] This design allows the branch pipe 22 and the second main pipe 212 to be connected in parallel to the first main pipe 211. When a negative pressure is generated in the first main pipe 211, the powder in the feeding container 10 can be drawn into the first main pipe 211 from the discharge port 12 through the second main pipe 212. At the same time, the powder thrown up in the feeding container 10 can be drawn into the first main pipe 211 through the branch pipe 22 and the dust suction pipe 30. Finally, the powder is collected and transported to the powder storage tank for storage and use through the first main pipe 211, thus achieving the functions of material suction and dust suction simultaneously. In addition, by setting an air inlet 211a at one end of the first main pipe 211, when a negative pressure is generated in the first main pipe 211, outside air can enter the first main pipe 211 through the air inlet 211a to smoothly suck up the powder, while avoiding the vacuum state of the feeding container 10 and each pipe under the action of negative pressure.
[0054] It should be noted that, due to the increased connection between the dust suction pipe 30 and the material suction pipe 20, sufficient negative pressure can be generated inside the material suction pipe 20 by reducing the area of the air inlet 211a.
[0055] Optionally, corresponding control valves can be installed on both the branch pipe 22 and the second main pipe 212 to control the opening or closing of the corresponding pipes, so that any pipe can be opened or closed during use.
[0056] Please see Figure 1 In one embodiment of this application, a magnetic structure 40 is provided on the branch pipe 22, and the magnetic structure 40 is configured to adsorb impurities in the powder flowing through the branch pipe 22.
[0057] The magnetic structure 40 refers to a structure used to attract impurities, such as a magnet, used to attract impurities such as iron, cobalt, nickel, and manganese in the powder. The magnetic structure 40 can be a magnetic rod or a magnetic plate, as long as it can attract impurities in the powder flowing through the branch pipe 22.
[0058] This design addresses the issue that when powder is added to the feeding container 10, the bag containing the powder is usually also added to the feeding container 10. However, the bag may contain impurities (such as iron, cobalt, nickel, manganese, etc.), which are easily drawn into the dust collection pipe 30 as the powder is thrown around. Therefore, by installing a magnetic suction structure 40 on the branch pipe 22, the impurities in the powder can be drawn away by the magnetic suction structure 40 as the powder flows from the dust collection duct to the branch pipe 22, thereby improving the purity of the powder.
[0059] Please see Figure 1 In one embodiment of this application, the magnetic attraction structure 40 is a magnetic rod, which is inserted into the branch pipe 22. This design allows the magnetic rod to be directly inserted into the branch pipe 22 during installation, facilitating the installation of the magnetic attraction structure 40.
[0060] A magnetic rod is a rod-shaped magnetic attraction component. The magnetic rod can be directly welded to the branch pipe 22, or it can be fixed to the branch pipe 22 by screws, clips, adsorption, or other methods.
[0061] In some embodiments, the branch pipe 22 is provided with an insertion port, through which one end of the magnetic rod can be inserted into the branch pipe 22.
[0062] Please see Figure 1 In one embodiment of this application, the magnetic structure 40 is detachably installed on the branch pipe 22.
[0063] The magnetic structure 40 can be detached and installed, which means that it can be removed from the branch pipe 22 and reinstalled by manual or mechanical means, and the magnetic structure 40 and the branch pipe 22 will not be damaged when the magnetic structure 40 is removed, so that the magnetic structure 40 can be reinstalled.
[0064] This design allows the magnetic structure 40 to be installed on the branch pipe 22 in a detachable manner. When a lot of impurities are adsorbed on the magnetic structure 40, the magnetic structure 40 can be removed from the branch pipe 22 to clean the impurities before being reinstalled on the branch pipe 22, thus facilitating the cleaning of the magnetic structure 40.
[0065] Please see Figure 1 In one embodiment of this application, a filter 50 is also provided on the branch pipe 22, and the filter 50 is configured to filter impurities in the powder flowing through the branch pipe 22.
[0066] A filter is a structure used to filter impurities. Optionally, filter 50 can be a filter structure with a filter screen. When powder flows through branch pipe 22, finer powder can pass through the holes in the filter screen and enter the main pipe 21, while impurities will be blocked on the filter screen, thus achieving filtration. Filter 50 can be directly welded to branch pipe 22, or it can be fixed to branch pipe 22 by screws, clips, adsorption, or other methods.
[0067] Furthermore, the filter 50 can be installed between the magnetic structure 40 and the inlet of the branch pipe 22, so that the powder can be filtered by the filter 50 first and then magnetically attracted by the magnetic structure 40; or, the filter 50 can also be installed between the magnetic structure 40 and the outlet of the branch pipe 22, so that the powder can be magnetically attracted by the magnetic structure 40 first and then filtered by the filter 50.
[0068] This design addresses the issue that the material bag may contain not only iron impurities but also other impurities (such as dirt, fragments from a broken material bag, etc.). These impurities are easily drawn into the dust collection pipe 30 as the powder is blown around. Therefore, by installing a filter 50 on the branch pipe 22, the impurities in the powder can be filtered out as it flows from the dust collection duct to the branch pipe 22, thereby further improving the purity of the powder.
[0069] Please see Figure 1 In one embodiment of this application, the magnetic suction structure 40 is disposed between the filter 50 and the inlet of the branch pipe 22.
[0070] This design allows the powder to be magnetically attracted by the magnetic structure 40 before being filtered by the filter 50. This allows some impurities to be adsorbed onto the magnetic structure 40 first, reducing the amount of impurities flowing to the filter 50 and preventing impurities from clogging the filter 50, thereby reducing the number of times the filter 50 needs to be cleaned.
[0071] Please see Figure 1 In one embodiment of this application, the filter 50 is detachably installed on the branch pipe 22.
[0072] The detachable installation of filter 50 refers to an installation method in which filter 50 can be removed and reinstalled from branch pipe 22 manually or mechanically, without damaging filter 50 or branch pipe 22, thus enabling reinstallation of filter 50. Filter 50 can be installed inside branch pipe 22; alternatively, filter 50 can be used to connect two sections of branch pipe 22 together.
[0073] This design allows the filter 50 to be installed on the branch pipe 22 in a detachable manner. When the filter 50 has filtered out a lot of impurities, it can be removed from the branch pipe 22 to clean the impurities before being reinstalled on the branch pipe 22, or a new filter 50 can be directly replaced, thus facilitating the cleaning and replacement of the filter 50.
[0074] Please see Figure 1 In one embodiment of this application, the feeding container 10 is provided with a liftable bag pressing structure 70, which is configured to press or release the bag containing powder in the feeding container 10.
[0075] The bag-pressing structure 70 refers to a structure that can press the material bag in the feeding container 10 against the inner wall of the feeding container 10 when it descends, and can release the pressing force on the material bag when it rises. In some embodiments, the bag-pressing structure 70 may include a cylinder and a pressure plate. Driven by the cylinder, the pressure plate can be raised and lowered to press or release the material bag containing powder in the feeding container 10 during the raising and lowering of the pressure plate.
[0076] With this design, when the bag containing powder is put into the feeding container 10, the suction pipe 20 will not suck up the powder all at once because the bag containing powder is relatively heavy. Therefore, in order to avoid the bag shifting as its weight gradually decreases, a bag pressing structure 70 is used to press the bag tightly.
[0077] Please see Figures 1 to 3In one embodiment of this application, the feeding container 10 is further provided with an overflow port 13, which is located between the feeding port 11 and the discharge port 12; the mixing device 100 also includes an overflow pipe 60, the inlet of which is connected to the overflow port 13 and the outlet of which is connected to the suction pipe 20. Under the negative pressure of the suction pipe 20, the powder in the feeding container 10 is sucked from the overflow port 13 into the overflow pipe 60.
[0078] Overflow port 13 refers to the outlet for the powder that overflows from the feeding container. The cross-sectional shape of the overflow port 13 can be circular, elliptical, rectangular, etc., and no specific limitation is made here.
[0079] The overflow pipe 60 is a pipe used to transport powder overflowing from the overflow port 13 into the suction pipe 20. The inlet end of the overflow pipe 60 can be connected to the side wall of the feeding container 10, or it can extend directly into the feeding container 10 from the overflow port 13, as long as the inlet of the overflow pipe 60 is connected to the overflow port 13 of the feeding container 10. The outlet end of the overflow pipe 60 can be connected to the side wall of the suction pipe 20, or it can extend directly into the suction pipe 20, as long as the outlet of the overflow pipe 60 is connected to the suction pipe 20.
[0080] With this design, when the bag containing powder is put into the feeding container 10, the bag will be compressed using a compression structure. During the compression process, the middle of the bag is prone to cracking and the powder will overflow. The overflowing powder can be sucked from the feeding container 10 through the overflow port 13 into the overflow pipe 60 under the negative pressure of the suction pipe 20, and then sucked into the suction pipe 20 through the overflow pipe 60, thereby improving the suction efficiency of the suction pipe 20.
[0081] According to some embodiments of this application, this application provides a stirring device 100. Please refer to [link to relevant documentation]. Figures 1 to 3 The mixing device 100 includes a feeding container 10, a suction pipe 20, a dust suction pipe 30, and a main body. The feeding container 10 has a feeding port 11 and a discharging port 12, with the feeding port 11 configured to feed powder. The inlet of the suction pipe 20 is connected to the discharging port 12, and a negative pressure is configured within the suction pipe 20. The inlet of the dust suction pipe 30 is connected to the feeding port 11, and the outlet of the dust suction pipe 30 is connected to the suction pipe 20. Under the negative pressure of the suction pipe 20, the powder in the feeding container 10 is sucked away from the discharging port 12, and the powder in the feeding container 10 is sucked into the suction pipe 20 through the dust suction pipe 30. The main body includes a powder storage tank, which is connected to the outlet of the suction pipe 20. A magnetic suction structure 40 and a filter 50 are provided on the branch pipes 22 of the suction pipe 20.
[0082] In the technical solution of this application embodiment, the dust suction pipe 30 is directly connected to the material suction pipe 20, so that the inlet of the dust suction pipe 30 is connected to the feeding port 11 of the feeding container 10, and the outlet of the dust suction pipe 30 is connected to the material suction pipe 20. When some powder flies during the powder feeding process, the powder can be directly sucked into the material suction pipe 20 through the dust suction pipe 30 under the negative pressure of the material suction pipe 20, and finally sucked into the powder storage tank for storage and use. Therefore, the dust can also be sucked away and utilized by the material suction pipe 20, realizing the purpose of turning waste into treasure; at the same time, the use of a dust collector is eliminated, and there is no need for manual disassembly and cleaning of the dust collector regularly. Therefore, this solution solves the problem of powder flying during cleaning causing occupational health and safety impacts on employees, and also causes powder waste. In addition, when the powder flows from the dust suction pipe to the branch pipe 22, some impurities in the powder can be sucked away by the magnetic suction structure 40, and the remaining impurities in the powder can be filtered by the filter 50, thereby improving the purity of the powder.
