Description

Technical Field

[0001] This utility model belongs to the field of mixing equipment, and more specifically relates to a positive and negative pressure integrated vacuum sending device for powder particles. Background Technology

[0002] In the process of conveying powder particles, it is often necessary to transfer them from one location to another, such as from a storage silo to processing equipment. Existing powder particle conveying equipment has many shortcomings. For example, some equipment can only achieve single positive or negative pressure conveying, which is relatively limited in function and cannot meet the diverse needs of different working conditions and material characteristics. Some equipment is prone to powder particle residue and pipeline blockage during the conveying process, affecting conveying efficiency and normal operation of the equipment. Other equipment has a complex structure, high cost, and is difficult to maintain, which is not conducive to large-scale promotion and application. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a vacuum conveying device integrating positive and negative pressure, which offers high working efficiency, prevents dust diffusion, maintains a clean transportation environment, prevents pollution, and is energy-efficient.

[0004] According to one aspect of this utility model, a positive and negative pressure integrated powder particle vacuum conveying device includes: a pressurizing component, a negative pressure component, a dust removal component, and a vacuum conveying tank component. The pressurizing component is connected to the bottom of the vacuum conveying tank component, and the dust removal component is installed on the top of the vacuum conveying tank component. The negative pressure component is connected to the vacuum conveying tank component through the dust removal component. This conveying method effectively avoids the problem of dust flying during the conveying process, not only reducing material loss but also significantly reducing pollution to the production environment. When the pressurizing component starts working, it generates a strong positive pressure airflow, which propels the material to move in an orderly manner within the mixing chamber and accurately pushes the material to the designated area. Positive pressure conveying has a strong driving force, enabling long-distance, high-pressure material conveying.

[0005] In some embodiments, the vacuum sending tank assembly includes: a tank body and a receiving cavity inside the tank body, an inlet and a first valve for opening and closing the inlet are provided above the tank body, and the inlet is in communication with the receiving cavity;

[0006] A discharge component is installed at the bottom of the tank, including a discharge port and a second valve for opening and closing the discharge port. The discharge port is connected to the receiving cavity. The inlet facilitates the feeding of materials into the receiving cavity, while the discharge port facilitates the long-distance transport of powder particles through pipelines.

[0007] In some embodiments, a pressure boosting pipe is provided below the tank body and communicates with the accommodating cavity. A third valve is provided on the pressure boosting pipe, and the pressure boosting pipe is connected to the pressure boosting assembly. The pressure boosting pipe facilitates the pressure boosting assembly to pressurize and transport powder particles into the accommodating cavity.

[0008] In some embodiments, the pressurization assembly includes: an air compressor, a first air tank, a first filter, a refrigerated dryer, a second filter, and a second air tank. The air compressor is connected to the pressurization pipe via a pipeline that sequentially includes: the first air tank, the first filter, the refrigerated dryer, the second filter, and the second air tank. When material enters the receiving chamber via the pressurization assembly, the equipment switches to positive pressure conveying mode. The air compressor starts working, generating a powerful positive pressure airflow that propels the material in an orderly manner within the mixing chamber and precisely pushes it to the designated area. Positive pressure conveying possesses strong driving force, enabling long-distance, high-pressure material transport and ensuring that materials accurately reach their destination even in complex pipeline layouts, meeting the needs of different production scenarios.

[0009] In some implementations, the first filter is a Class C filter, or a Class Q or Class P filter, and multiple filtration devices are used to filter the compressed air to ensure a clean environment for powder particle conveying.

[0010] In some embodiments, the dust collection assembly includes: a dust collector, a pneumatic ball valve, a blowpipe, a first pulse solenoid valve, an air reservoir, and a filter element. The bottom of the dust collector and the top of the tank are connected by a first chuck. The pneumatic ball valve is installed on the top of the dust collector, and its bottom is connected to the blowpipe. The first pulse solenoid valve is installed on the blowpipe and connected to the air reservoir, which is connected to an external air source. The filter element is removably installed inside the dust collector. The exhaust gas is filtered by the dust collection assembly.

[0011] In some embodiments, the negative pressure assembly includes a negative pressure generating device and a filter storage tank. The negative pressure generating device is connected to the filter storage tank, which is connected to a first pulse solenoid valve. Through the negative pressure assembly, the vacuum pump operates rapidly, creating a negative pressure environment inside the conveying pipeline and mixing chamber. Under the pressure difference between the external atmospheric pressure and the internal negative pressure of the equipment, the material is smoothly drawn into the conveying pipeline from the inlet and then smoothly enters the mixing chamber. This conveying method effectively avoids the problem of dust flying during the conveying process, not only reducing material loss but also significantly reducing pollution to the production environment, creating a clean and healthy working space for operators.

[0012] In some implementations, a pressure sensor that communicates with the accommodating cavity is installed on the tank.

[0013] In some embodiments, a first level gauge is installed above the tank, and a second level gauge is installed below the tank.

[0014] Compared with existing technologies, this invention has the advantages of high working efficiency, efficient conveying, precise control, and wide applicability. This invention uses a negative pressure component to smoothly draw material from the inlet into the conveying pipe, and then into the mixing chamber. This conveying method effectively avoids dust flying during the conveying process, reducing material loss and significantly lowering pollution to the production environment. The pressurization component generates a powerful positive pressure airflow, propelling the material in an orderly manner within the mixing chamber and precisely pushing it to the designated area. Positive pressure conveying has strong driving force, enabling long-distance, high-pressure material conveying. The inlet facilitates the input of material into the receiving chamber, and the outlet facilitates the long-distance conveying of powder particles through the pipe. The pressurization pipe allows the pressurization component to pressurize and convey powder within the receiving chamber. Particles; after the material enters the receiving chamber via the pressurization component, the equipment switches to positive pressure conveying mode. The compressed air device starts working, generating a strong positive pressure airflow, which propels the material to move in an orderly manner within the mixing chamber and precisely pushes the material to the designated area. Positive pressure conveying has a strong driving force, enabling long-distance, high-pressure material conveying, ensuring that the material can accurately reach its destination even in complex pipeline layouts, meeting the needs of different production scenarios; the exhaust gas is filtered by the dust removal component; the compressed air is filtered through multiple filtration devices to ensure a clean environment for powder and particle conveying.

[0019] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0020] In the description of this invention, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the terms according to the specific circumstances.

[0021] like Figure 1 As shown, the positive and negative pressure integrated powder and particle vacuum conveying device of this utility model includes: a pressurizing component 1, a negative pressure component 2, a dust removal component 3, and a vacuum conveying tank component 4. The pressurizing component 1 is connected to the bottom of the vacuum conveying tank component 4, and the dust removal component 3 is installed on the top of the vacuum conveying tank component 4. The negative pressure component 2 is connected to the vacuum conveying tank component 4 through the dust removal component 3. This conveying method effectively avoids the problem of dust flying during the conveying process, which not only reduces material loss but also significantly reduces pollution to the production environment. When the pressurizing component 1 starts working, it generates a strong positive pressure airflow, which propels the material to move in an orderly manner in the mixing chamber and accurately pushes the material to the designated area. Positive pressure conveying has a strong driving force and can realize long-distance, high-pressure conveying of materials.

[0022] The vacuum sending tank assembly 4 includes: a tank body 41 and a receiving cavity 42 inside the tank body 41. A feed inlet 43 and a first valve 44 for opening and closing the feed inlet 43 are provided above the tank body 41. The feed inlet 43 is connected to the receiving cavity 42.

[0023] A discharge component is provided at the bottom of the tank body 41. The discharge component includes a discharge port 45 and a second valve 46 for opening and closing the discharge port 45. The discharge port 45 is connected to the receiving cavity 42. The material can be easily fed into the receiving cavity 42 through the feed port 43, and the powder particles can be easily transported over long distances through the discharge port 45.

[0024] A pressure boosting pipe 5 is provided below the tank body 41 and communicates with the accommodating cavity 42. A third valve 6 is provided on the pressure boosting pipe 5. The pressure boosting pipe 5 is connected to the pressure boosting component 1. The pressure boosting pipe 5 facilitates the pressure boosting component 1 to pressurize and transport powder particles in the accommodating cavity 42.

[0025] like Figure 2As shown, the pressurization assembly 1 includes: an air compressor 11, a first air tank 12, a first filter 13, a refrigerated dryer 14, a second filter 15, and a second air tank 16. The air compressor 11 is connected to the pressurization pipe 5 via the following components in sequence: the first air tank 12, the first filter 13, the refrigerated dryer 14, the second filter 15, and the second air tank 16. When material enters the receiving chamber 42 via the pressurization assembly 1, the equipment switches to positive pressure conveying mode. The air compressor 11 starts working, generating a powerful positive pressure airflow that propels the material to move in an orderly manner within the mixing chamber and precisely pushes the material to the designated area. Positive pressure conveying has a powerful driving force, enabling long-distance, high-pressure material conveying, ensuring that the material accurately reaches its destination even in complex pipeline layouts, meeting the needs of different production scenarios.

[0026] The refrigerated dryer 14 uses refrigerant to exchange heat with compressed air, reducing the temperature of the compressed air to a dew point temperature in the range of 2 to 10°C. Then, it dries the air compressed by the air compressor 11 to prevent the moisture content of the conveyed powder particles from exceeding the standard.

[0027] The first filter 13 is a Class C filter, and the second filter 15 is a Class Q or Class P filter. The compressed air is filtered through multiple filtration devices to ensure a clean environment for the transport of powder particles.

[0028] The first filter 13 is a Class C filter, which uses a fine fiber mesh to effectively filter out particles with a diameter greater than 0.5 micrometers, such as dust and pollen.

[0029] The second filter 15 is either a Q-class or P-class filter. The Q-class filter, as the main pipeline filter, primarily removes large amounts of liquid and solid particles larger than 3μm, ensuring that the residual oil content is only 5ppm. The P-class filter can filter out liquid and solid particles as small as 1μm.

[0030] Depending on different filtration requirements, multiple second filters 15 can be set, which can be the same Q-level or P-level filters, or one or more different Q-level and P-level filters.

[0031] like Figure 3 As shown, the dust collection assembly 3 includes: a dust collector 31, a pneumatic ball valve 32, a blowpipe 33, a first pulse solenoid valve 34, an air tank 35, and a filter element 36. The bottom of the dust collector 31 and the top of the tank 41 are connected by a first chuck 37. The pneumatic ball valve 32 is installed on the top of the dust collector 31, and the bottom of the pneumatic ball valve 32 is connected to the blowpipe 33. The first pulse solenoid valve 34 is installed on the blowpipe 33 and is connected to the air tank 35. The air tank 35 is connected to an external air source. The filter element 36 is detachably installed inside the dust collector 31. The dust collection assembly 3 filters the discharged gas.

[0032] like Figure 4 As shown, the negative pressure assembly 2 includes a negative pressure generating device 21 and a filter storage tank 22. The negative pressure generating device 21 is connected to the filter storage tank 22, and the filter storage tank 22 is connected to the first pulse solenoid valve 34. Through the negative pressure assembly 2, the vacuum pump operates rapidly, creating a negative pressure environment inside the conveying pipeline and mixing chamber. At this time, under the pressure difference formed by the external atmospheric pressure and the negative pressure inside the equipment, the material is smoothly drawn into the conveying pipeline from the feed inlet 43 and then smoothly enters the mixing chamber. This conveying method effectively avoids the problem of dust flying during the conveying process, not only reducing material loss but also significantly reducing pollution to the production environment, creating a clean and healthy working space for operators.

[0033] A pressure sensor 7 is installed on the tank 41 and communicates with the receiving cavity 42. The pressure sensor 7 accurately detects the pressure inside the receiving cavity 42, which facilitates precise control of the delivery pressure.

[0034] A first level gauge 8 is installed above the tank body 41, and a second level gauge 9 is installed below the tank body 41. The first level gauge 8 and the second level gauge 9 are used to facilitate the detection of the amount of powder particles in the accommodating cavity 42.

[0035] During use, first turn on the negative pressure component 2, and the vacuum pump will start operating quickly, creating a negative pressure environment in the conveying pipe and mixing chamber. At this time, under the pressure difference between the external atmospheric pressure and the negative pressure inside the equipment, the material is smoothly sucked into the conveying pipe from the feed inlet 43 and then smoothly enters the receiving chamber 42.

[0036] Finally, the pressurization component 1 operates, driving the material to move in an orderly manner within the accommodating cavity 42, and accurately pushing the material to the designated area to achieve long-distance, high-pressure material transportation.

[0037] This invention also features an intelligent positive / negative pressure switching system, capable of real-time monitoring of internal pressure changes, material conveying status, and production process requirements. Based on this precise data, it rapidly and smoothly switches between positive and negative pressure conveying modes within milliseconds. The entire switching process requires no manual intervention, not only improving the automation level and operating efficiency of the equipment but also significantly reducing the risk of production failures due to human error, ensuring the continuity and stability of the production process.

[0038] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
