[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Moreover, for the purpose of clearly describing the present utility model, some components have been exaggerated. These do not constitute any limitation on the scope of protection of the present utility model.

[0022] This invention provides a feeding system suitable for powdery materials such as metal powder and plastic particles, as well as mixtures of powder and granules. It can automatically convey various materials to the hoppers of packaging machines, injection molding machines, crushers, and other equipment. It can also directly convey mixtures to mixers (such as V-type mixers, two-dimensional mixers, three-dimensional mixers, etc.) and the hoppers of 3D printers, effectively reducing the labor intensity of workers and solving problems such as dust spillage during material feeding. The feeding system includes a feeding device and a vortex blower. The feeding device includes a through conveying channel, with a conveying gas inlet at one end and a conveying outlet at the other end. The conveying channel has an inner constriction and a corresponding material inlet, through which a material storage container can be connected. The outlet of the vortex blower is connected to the conveying gas inlet of the feeding device to provide conveying gas. The conveying gas is accelerated when passing through the inner constriction, and the pressure at or near the inner constriction decreases due to the accelerated airflow, creating a pressure difference with the pressure inside the material container. Under negative pressure, the material inside the material container is sucked out, forming a mixture with the conveying gas. Driven by a continuous flow of gas, the mixture of gas and material is output from the conveyor outlet. After subsequent material separation, the material is conveyed to the required equipment.

[0023] Figure 1 A schematic diagram of an exemplary feeding system of this utility model is shown. Figure 2 It shows Figure 1 A schematic diagram of an exemplary structure of the feeding device 1 in the diagram. Figure 1 and Figure 2 As shown, the feeding system includes a feeding device 1, a vortex blower 2, and a distributor 3. The feeding device 1 includes a conveying channel 12, one end of which is a conveying gas inlet 13, and the other end is a conveying outlet 14. The conveying channel 12 is provided with an inward section 15, and a material inlet 16 corresponding to the inward section 15. The material inlet 16 is connected to a material storage container 5 through a connecting valve 18.

[0024] The outlet 21 of the vortex blower 2 is connected to the conveying gas inlet 13 of the feeding device 1 to provide conveying gas. The conveying gas is accelerated as it passes through the constriction section 15, creating a negative pressure, and draws material out of the material storage container 5 through the material inlet 16 to form a mixture. The mixture is output from the conveying outlet 14 under the continuous push of the conveying gas.

[0025] The conveying outlet 14 of the feeding device 1 is connected to the inlet of the separator 3 via a pipeline. The mixture enters the separation space of the separator 3 through the inlet of the separator 3 for separation. In the separation space of the separator 3, the mixture is separated into conveying gas and material. The conveying gas is output through the gas outlet. The gas outlet of the separator is connected to the inlet of the vortex blower via a pipeline. The gas separated in the separator enters the inlet 22 of the vortex blower 2 through a pipeline. The material falls to the bottom of the separation space and enters the connected device through the material outlet.

[0026] To ensure efficient feeding, a certain pressure needs to be maintained in the gas circulation pipeline. Therefore, a gas replenishment port 23 can be installed in the pipeline between the gas inlet 13 of the feeding device 1 and the outlet 21 of the vortex blower 2, allowing for gas replenishment as needed to maintain a certain pressure in the gas circulation pipeline.

[0027] A gas flow regulating valve 17 can be installed on the pipeline between the gas inlet and the gas replenishment port of the feeding device to adjust the flow rate of the conveying gas, thereby regulating the feeding amount.

[0028] The image below is passed Figure 2 The structure of the feeding device 1 is further illustrated. The feeding device 1 is tubular, with a conveying channel 12 forming through it. The shape of the feeding device is not limited to tubular; any through conveying channel is sufficient. One end of the conveying channel 12 is a conveying gas inlet 13, which can be connected to a conveying gas source, such as a vortex blower 2, to allow the conveying gas to flow into the conveying channel. The conveying gas is a pressurized gas. The other end of the conveying channel is a conveying outlet 14. A concave portion 15 is provided between the conveying gas inlet 13 and the conveying outlet 14 of the conveying channel 12. A material inlet 16 is correspondingly provided on the conveying pipe to the concave portion 15. The material inlet 16 may be equipped with a connecting valve 18 for connecting to and facilitating the replacement of material storage containers or equipment. When the conveying gas flows through the concave portion 15, i.e., above the opening of the material storage container, it is accelerated, creating a pressure difference that draws the material out and into the conveying channel 12, where it mixes with the conveying gas and is then conveyed out from the conveying outlet 14 under the impetus of the conveying gas.

[0029] Figure 3A schematic diagram of another exemplary feeding device 21 is shown. In this example, the feeding device 21 is tubular, with a conveying channel 212 formed through it. One end of the conveying channel 212 is a conveying gas inlet 213. The other end of the conveying channel 212 is a conveying outlet 214. A nozzle 219 is provided at the conveying gas inlet 213, which is configured to extend into the conveying channel and has a concave portion 215. A material inlet 216 is correspondingly provided on the conveying channel with the concave portion 215. The conveying gas is input through the nozzle 219, accelerated as it passes through the concave portion 215, creating a pressure difference, and the material is drawn out and enters the conveying channel 212 to form a mixture with the conveying gas. The mixture is output from the conveying outlet 214 under the impetus of the conveying gas.

[0030] Figure 1 The structure of the separation device 3 in the middle is as follows Figure 4 As shown, the separation device 3 includes a sealed housing 31, forming a separation space for a mixture of material and conveying gas. The sealed housing 31 has an inlet 32, a gas outlet 33, and a material outlet 34. The inlet 32 ​​is connected to the conveying outlet of a feeding device via a pipeline. The gas outlet 33 is located at the top of the sealed housing 31 and is connected to the air inlet 22 of the vortex blower 2 via a pipeline, forming a gas circulation. A filter 35 is installed at the gas outlet 33 inside the sealed housing 31 to filter the material from the mixture. The material outlet 34 is located at the bottom of the sealed housing 31 for connecting to necessary devices.

[0031] The filter 35 can preferably be a sintered filter. To prevent the filter from being clogged by accumulated material, an acoustic soot blower (not shown) can be installed inside the filter to blow out the material accumulated in the filter, thereby ensuring the filtration effect of the filter, avoiding frequent filter replacement, and improving work efficiency.

[0032] Material outlet 34 may be equipped with a connecting valve 36, allowing connection to various containers or processing devices. Material can, for example, enter the desired container 4 through material outlet 34.

[0033] The following is based on Figure 1The following describes the working process of the feeding system using an example. The vortex blower 2 inputs the conveying gas into the conveying gas inlet 13 of the feeding device 1 through a pipeline, entering its conveying channel 12. Because the conveying channel has a concave section 15, the pressure decreases at or near the concave section 15 due to airflow acceleration, creating a pressure difference with the pressure inside the material container 5. Under negative pressure, the material inside the material container 5 is sucked out, forming a mixture with the conveying gas. The mixture is pushed out of the conveying outlet 14 of the feeding device 1 by the continuously input conveying gas, and enters the inlet 32 ​​of the separator 3 through a pipeline, thus entering the separation space of the sealed housing 31 of the separator 3. Due to the continuous input of the conveying gas, a cyclone is formed in the separation space of the sealed housing 31 of the separator 3, and flows through the filter 35 located at the gas outlet 33 inside the sealed housing 31. After filtration by the filter 35, the mixture is separated into conveying gas and material. The conveying gas flows out from the gas outlet 33 and enters the inlet 22 of the vortex blower 2 through a pipeline, realizing gas circulation. When the gas pressure in the entire circulation system is insufficient, supplemental gas can be supplied through the gas supply port 23. The material remains inside the sealed housing 31 of the separator 3, falls to the bottom of the sealed housing 31, and enters the container 4 through the material outlet 34. Depending on the device connected to the material outlet 34, the material conveying rate can be adjusted by the gas flow regulating valve 17 to meet the needs of different devices.

[0034] The feeding device of this invention has a simple structure, realizes automatic negative pressure material suction, has high working efficiency, and can be easily moved for connection with other devices for feeding operations. Since the gas outlet of the separation device is connected to the air inlet of the vortex blower 2 through a pipeline, a gas circulation is formed, which not only meets the requirements of the inert gas operating environment but also ensures that the material is isolated from the outside air, reducing the risk of material contamination and minimizing air pollution.

[0035] The feeding system provided by this utility model adopts negative pressure suction and positive pressure feeding, which has advantages over negative pressure feeding. When the system or pipeline connection is faulty, leaks in positive pressure feeding are obvious and easy to handle, while air ingress is difficult to detect in negative pressure feeding. Furthermore, the feeding system of this utility model has a simple structure, reasonable design, and is easy to operate and maintain. All parts are conveniently installed and connected, and the system is movable, capable of feeding multiple devices simultaneously, eliminating the tedious manual feeding process and making feeding safer, more time-saving, and less labor-intensive. It also boasts high efficiency, with a maximum feeding capacity of 3 tons per hour; a wide range of applications, suitable for powders, plastic granules, and powder-granule mixtures; and it achieves gas circulation with low energy consumption, with the vortex blower powering only 400W, saving costs.

[0036] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
