Description

Technical Field

[0001] The utility model relates to the technical field of powder feeding, in particular to a combined powder feeding device. Background Art

[0002] In modern industrial production, the feeding operation of powder materials is a key link in many production processes. It mainly refers to the operation process of transferring powdered or granular solid materials from storage containers to production equipment. The accuracy and uniformity of powder feeding are directly related to the quality of the product.

[0003] Chinese utility model patent announcement number: CN 216971388 U, discloses: a powder feeding device, which can realize automatic feeding by setting a feeding component, greatly improving feeding efficiency, and greatly reducing labor. At the same time, the internal feeding method can greatly reduce the damage of powder to the human body; by setting an expansion component, the thick blade can be rotated inside the powder bag to expand and expand the opening, thereby accelerating the fall of the powder, thereby improving work efficiency. However, the powder feeding device, through the internal feeding method, needs to introduce the powder bag into the interior for feeding, which takes a long time and reduces the working efficiency. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a combined powder feeding device, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by the utility model is: a combined powder feeding device, comprising a bracket one, the upper end of the bracket one is fixedly connected to a barrel, the outer side of the barrel is fixedly connected to a motor one, the output end of the motor one is fixedly connected to a striking rod, the upper end of the barrel is fixedly connected to a motor two, the output end of the motor two is fixedly connected to a rotating shaft, the outer side of the rotating shaft is fixedly connected to a stirring blade, the upper end of the barrel is fixedly connected to a feeding assembly, the lower end of the barrel is fixedly connected to a discharge pipe, the lower end of the discharge pipe is fixedly connected to the input end of a fan one, the outer side of the discharge pipe is fixedly connected to an air supply pipe, the air supply pipe is fixedly connected to a filter, the outer side of the discharge pipe is fixedly connected to a connecting pipe, a bracket two is provided on the left side of the bracket one, the upper end of the bracket two is fixedly connected to a pulse dust collector, the feeding end of the pulse dust collector is fixedly connected to a dust inlet pipe, and the lower end of the pulse dust collector is fixedly connected to a fan two;

[0006] The feeding assembly includes a feeding pipe, an air suction hood, an air bag and an air pipe. The outer side of the feeding pipe is fixedly connected to the air suction hood, the front end of the feeding pipe is fixedly connected to the air bag, and the front end of the air bag is fixedly connected to the air pipe.

[0007] Preferably, the barrel has a cylindrical structure, and the striking rod is made of fluororubber.

[0008] Through the above technical solution, the striking rod is made of fluororubber, which has excellent chemical corrosion resistance, can prevent reactions with powders of different chemical properties, and maintain its own stable performance. At the same time, its good flexibility and elasticity enable the striking rod to effectively strike the agglomerated powder under the drive of motor 1 without being easily damaged by long-term impact, thereby ensuring the loose state of the powder in the barrel, which is conducive to the smooth progress of subsequent unloading operations.

[0009] Preferably, the stirring blades are sickle-shaped and evenly distributed on the outside of the rotating shaft.

[0010] With this technical solution, the sickle-shaped stirring blades create a strong shear force on the powder when the motor drives the shaft. This shear force effectively breaks down lumps in the powder, making the powder particles more uniform. The stirring blades work in conjunction with the cylindrical barrel to avoid dead corners, further improving the stirring effect and ensuring stable powder quality upon discharge.

[0011] Preferably, the air suction hood is arranged on the left side, right side and rear end of the feed pipe, and the air suction hood and the dust inlet pipe are connected to each other.

[0012] Through the above technical solution, the setting of the suction hood on three sides of the feed pipe forms a more comprehensive dust suction area. During the feeding process, no matter which direction the dust is raised from, it can be captured by the suction hood. The suction hood is connected to the dust inlet pipe, so that the captured dust can be promptly transported to the pulse dust collector for processing, which can greatly reduce the diffusion of dust around the feed pipe, keep the working environment clean and hygienic, and protect operators from dust hazards.

[0013] Preferably, a feeding port is provided at the front end of the feed pipe, and the inner wall of the feeding port is fixedly connected to the airbag. The airbag is made of chloroprene rubber, and the air supply pipe is connected to an external inflation and deflation air pump.

[0014] The above technical solution ensures a tight seal by securely connecting the feeding port and the airbag. The airbag is made of chloroprene rubber, which has excellent weather resistance, ozone resistance, and chemical resistance, making it adaptable to complex working environments. During use, the airbag's inflation and deflation can be easily controlled via an air pipe in conjunction with an external pump. The inflated airbag fits tightly against the packaging bag being fed, effectively preventing powder leakage from the feeding port during the feeding process. This ensures accurate feeding and a clean environment, while also avoiding powder waste.

[0015] Preferably, the filter is a cartridge filter device.

[0016] Through the above technical solution, the filter of the cartridge filter device has high filtration accuracy, can effectively filter out tiny impurities in the air entering from the air supply pipe, can prevent impurities from entering the discharge pipe and mixing with the powder, and ensure the purity of the powder.

[0017] Preferably, the second output end of the fan is communicated with the connecting pipe, and the first output end of the fan is fixedly connected to an external silo.

[0018] Through the above technical solution, fan 2 is connected to the connecting pipe, so that the dust collected by the pulse dust collector can pass through the connecting pipe. Fan 1 is connected to the external silo, which can accurately control the delivery amount and delivery speed of the powder output from the discharge pipe to the silo.

[0019] Compared with the prior art, the present invention provides a combined powder feeding device with the following beneficial effects:

[0020] 1. This combined powder feeding device has a beating rod driven by motor one and a stirring blade driven by motor two in the barrel.

The two work together to effectively break up the agglomerates in the powder, keeping the powder in a uniform particle state, greatly improving the smoothness of feeding and the efficiency of powder processing, and ensuring the stability of feeding quality.

[0021] 2. This combined powder feeding device has suction hoods installed on three sides of the outer side of the feed pipe, which are connected to the pulse dust collector through the dust inlet pipe. During the feeding process, it can capture dust in all directions, effectively preventing dust from spreading in the feeding area, greatly reducing dust pollution to the working environment, and protecting the health of operators. The inner wall of the feeding port at the front end of the feed pipe is tightly connected to the air bag made of neoprene, and inflation and sealing are achieved through the air pipe and the external charging and discharging air pump. During the feeding process, it can effectively prevent powder from leaking from the feeding port, avoiding powder waste, while keeping the work area clean and tidy.

[0022] 3. The combined powder feeding device has an air supply pipe and a filter connected to the outside of the discharge pipe, which can replenish the discharge pipe with filtered clean air, effectively balance the air pressure in the discharge pipe, improve the fluidity of the powder, prevent the powder from clogging the pipe during the discharge process, and ensure the continuity and stability of the discharge.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Figure 1-5 As shown, the utility model provides a combined powder feeding device, including a bracket 1, the upper end of the bracket 1 is fixedly connected to a barrel 2, the outer side of the barrel 2 is fixedly connected to a motor 3, the output end of the motor 3 is fixedly connected to a striking rod 4, the upper end of the barrel 2 is fixedly connected to a motor 2 5, the output end of the motor 2 5 is fixedly connected to a rotating shaft 6, the outer side of the rotating shaft 6 is fixedly connected to a stirring blade 7, the upper end of the barrel 2 is fixedly connected to a feeding assembly 9, the lower end of the barrel 2 is fixedly connected to a discharge pipe 10, the lower end of the discharge pipe 10 is fixedly connected to the input end of a fan 11, the outer side of the discharge pipe 10 is fixedly connected to an air supply pipe 12, the air supply pipe 12 is fixedly connected to a filter 13, the outer side of the discharge pipe 10 is fixedly connected to a connecting pipe 14, a bracket 2 is provided on the left side of the bracket 1, the upper end of the bracket 2 15 is fixedly connected to a pulse dust collector 16, the feeding end of the pulse dust collector 16 is fixedly connected to a dust inlet pipe 17, and the lower end of the pulse dust collector 16 is fixedly connected to a fan 2 18;

[0031] The feeding assembly 9 includes a feeding pipe 901, an air suction hood 902, an air bag 903 and an air supply pipe 904. The outside of the feeding pipe 901 is fixedly connected to the air suction hood 902, the front end of the feeding pipe 901 is fixedly connected to the air bag 903, and the front end of the air bag 903 is fixedly connected to the air supply pipe 904.

[0032] Specifically, the barrel 2 is cylindrical, and the striking rod 4 is made of fluororubber. Advantageously, the striking rod 4 is made of fluororubber, which has excellent chemical corrosion resistance, preventing reactions with powders of different chemical properties and maintaining its own stable performance. Furthermore, its excellent flexibility and elasticity enable the striking rod 4, driven by the motor 3, to effectively strike agglomerated powders without being easily damaged by long-term impact, thereby ensuring a loose state of powder within the barrel 2 and facilitating smooth subsequent unloading operations.

[0033] Specifically, the stirring blades 7 are evenly distributed on the outside of the rotating shaft 6 in a sickle-shaped structure. Advantageously, when the motor 2 5 rotates the rotating shaft 6, the sickle-shaped stirring blades 7 can exert a significant shear force on the powder. This shear force effectively breaks down lumps in the powder, resulting in more uniform powder particles. The stirring blades 7 cooperate with the cylindrical barrel 2 to avoid dead zones in the stirring process, further improving the stirring effect and ensuring stable powder quality upon discharge.

[0034] Example 2: Figure 2-5 As shown, it is an improvement to the previous embodiment.

[0035] Specifically, the suction hoods 902 are arranged on the left side, right side and rear end of the feed pipe 901, and the suction hoods 902 are interconnected with the dust inlet pipe 17. The advantage is that the arrangement of the suction hoods 902 on three sides of the feed pipe 901 forms a relatively comprehensive dust collection area. During the feeding process, no matter which direction the dust is raised from, it can be captured by the suction hoods 902. The suction hoods 902 are connected to the dust inlet pipe 17, so that the captured dust can be promptly transported to the pulse dust collector 16 for processing, which can greatly reduce the diffusion of dust around the feed pipe 901, maintain a clean and hygienic working environment, and protect operators from dust hazards.

[0036] Specifically, a feeding port is provided at the front end of the feed pipe 901, and the inner wall of the feeding port is fixedly connected to the airbag 903. The airbag 903 is made of chloroprene rubber, and the air supply pipe 904 is connected to an external inflation and deflation air pump. The advantage is that the fixed connection between the feeding port and the airbag 903 ensures the tightness of the seal. The airbag 903 is made of chloroprene rubber, which has good weather resistance, ozone resistance, and chemical corrosion resistance and can adapt to complex working environments. During use, the inflation and deflation of the airbag 903 can be easily controlled by cooperating with the external inflation and deflation air pump through the air supply pipe 904. The inflated airbag 903 can fit tightly against the packaging bag for feeding, effectively preventing powder from leaking from the feeding port during the feeding process, ensuring the accuracy of feeding and the cleanliness of the environment, while also avoiding powder waste.

[0037] Specifically, the filter 13 is a cartridge filter device. The advantage is that the filter 13 of the cartridge filter device has high filtering accuracy and can effectively filter out tiny impurities in the air entering from the air supply pipe 12, thereby preventing impurities from entering the discharge pipe 10 and mixing with the powder, thereby ensuring the purity of the powder.

[0038] Specifically, the output end of fan 2 18 is connected to connecting pipe 14, while the output end of fan 11 is fixedly connected to an external silo. Advantageously, the connection between fan 2 18 and connecting pipe 14 allows dust collected by pulse dust collector 16 to pass through connecting pipe 14. Fan 1 11 is connected to the external silo, enabling precise control of the amount and speed of powder delivered from discharge pipe 10 to the silo.

[0039] Working principle: When in use, start the external charging and discharging air pump, inflate the airbag 903 at the front end of the feeding tube 901 through the air supply pipe 904, so that the airbag 903 expands and fits tightly to the feeding port, align the packaging bag filled with powder with the feeding port of the feeding tube 901, and feed the material into the feeding tube 901. During the feeding process, the suction hood 902 on the outside of the feeding tube 901 starts to work, and the dust generated by the feeding is sucked away through the dust inlet pipe 17 and transported to the pulse dust collector 16. The pulse dust collector 16 performs dust removal on the inhaled dust-containing gas. After the powder enters the barrel 2, start the motor 1 3 and the motor 2 5. The motor 1 3 drives the striking rod 4 to strike the powder in the barrel 2 to break up the powder lumps. The motor 2 5 drives the rotating shaft 6 rotates, so that the sickle-shaped stirring blades 7 on the outside stir the powder, further breaking up the lumps and mixing the powder evenly, ensuring the stability of the powder quality of the discharge, and the treated powder is discharged through the discharge pipe 10 under the action of gravity. In this process, the clean gas filtered by the filter 13 through the air supply pipe 12 is timely replenished with gas into the discharge pipe 10 to maintain the air pressure balance in the discharge pipe 10, improve the powder fluidity, and prevent the pipeline from being blocked. The fan 11 is started to transport the powder to the external silo. In the pulse dust collector 16, the collected powder is gathered at the lower end under the action of gravity. The fan 2 18 is started and injected into the discharge pipe 10 through the connecting pipe 14 and discharged together with the powder in the barrel 2.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
