[0032] Example 1

[0033] refer to Figure 1 As shown, an embodiment of the present application provides a device 100 for preventing powder accumulation, which includes at least a cylinder 110 , an air outlet assembly 120 , a dust removal assembly 130 and a control assembly 140 .

[0034] Specifically, if Figure 1As shown, the cylinder 110 is provided with a accommodating cavity 111. The air outlet assembly 120 is provided with a plurality of air outlets 121, and the air outlets 121 extend into the accommodating cavity 111. The blowing direction of the air outlets 121 is toward the side wall surface of the accommodating cavity 111, so that the air outlets 121 of the air outlet assembly 120 can generate an air flow passing through the air flow path. The dust removal assembly 130 includes a dust suction pipe 131, and the dust suction pipe 131 extends into the accommodating cavity 111. The dust suction port of the dust suction pipe 131 is located at one end of the air flow path of the air flow away from the air outlet 121. The control component 140 is electrically connected to the air outlet component 120 and the dust removal component 130 respectively; when the air outlet component 120 is turned on, the control component 140 controls the operation of the dust removal component 130, and accordingly, the powder is discharged through the accommodating cavity 111 of the cylinder 110, and the air outlet component 120 can generate an air source, and the air outlet 121 of the air outlet component 120 blows air to the side wall surface of the accommodating cavity 111 of the cylinder 110, so that an air flow is generated in the accommodating cavity 111 of the cylinder 110, which is conducive to blowing away the water vapor in the accommodating cavity 111 and reducing the side wall surface of the accommodating cavity 111 of the cylinder 110. In the case where the accumulated powder is in the form of clumps under the action of water vapor, the dust removal component 130 can absorb the powder or powder clumps with water vapor, reducing the overflow of powder during the blowing process, and when the air outlet component 120 is turned on, the dust removal component 130 is controlled by the control component 140 to start, so as to achieve the purpose of making the air outlet component 120 and the dust removal component 130 work together to process the powder, so that the dust removal component 130 is used in conjunction with the air outlet component 120 to realize the suction of the incoming integrated dust through the dust removal component 130, reducing the accumulation of powder in the cylinder 110 that affects the quality of the finished product, thereby improving the yield rate.

[0035] In addition, when the air outlet component 120 is closed, the control component 140 controls the dust removal component 130 to be closed, that is, when the air outlet component 120 stops running, the dust removal component 130 can be controlled to stop running through the control component 140, thereby preventing the dust removal component 130 from accidentally sucking in the powder in the hopper when running alone, and reducing the accumulation of powder on the side wall of the accommodating chamber 111 of the cylinder 110.

[0036] It is understandable that the control component 140 includes a controller, and the controller can control the air outlet component 120 and / or the dust removal component 130 to be turned on, and the controller can also control the air outlet component 120 and / or the dust removal component 130 to be turned off. The controller can be an integrated circuit chip with signal processing capabilities. The above-mentioned controller can be a general-purpose processor, and the controller can implement or execute the control method in the embodiment of the present application. In a feasible embodiment, the control component 140 also includes a memory for storing program instructions that can be executed by the controller. The memory can also be integrated with the controller, for example, the memory can be integrated with the controller in the same chip.

[0037] In one embodiment, optionally, reference Figure 1 and Figure 2 As shown, the number of the air outlets 121 of the air outlet component 120 is multiple, and the number of the cylinders 110 is multiple, and one air outlet 121 corresponds to one cylinder 110, that is, one air outlet 121 of the air outlet component 120 is used to blow air into the accommodating cavity 111 of one cylinder 110, so that air flow is generated in the accommodating cavity 111, and the accumulation of powder on the side wall of the accommodating cavity 111 is reduced. The multiple air outlets 121 of the air outlet component 120 can be used to blow air to multiple cylinders 110 respectively, so as to improve the blowing efficiency of the multiple cylinders 110, which has a better technical effect. Optionally, as Figure 2 As shown, there are two air outlets 121, and the two air outlets 121 are in a "Y"-shaped structure. The number of the cylinders 110 is two, so that each air outlet 121 corresponds to one cylinder 110, that is, two air outlets 121 branch out from a main channel to form a "Y"-shaped structure. The two air outlets 121 in the "Y"-shaped structure reduce the resistance of the air flow when passing through, improve the air outlet efficiency, and the air flow in the air outlet component 120 can be diverted toward the two cylinders 110 through the two air outlets 121, and the two cylinders 110 can be blown at the same time.

[0038] Optionally, the two air outlets 121 are respectively provided with a first regulating valve 1211 and a second regulating valve 1212, the first regulating valve 1211 is electrically connected to the control component 140, and the second regulating valve 1212 is electrically connected to the control component 140. In other words, the air flow rate of one air outlet 121 is adjusted by the first regulating valve 1211, and the air flow rate of the other air outlet 121 is adjusted by the second regulating valve 1212, so as to realize the separate control of the air flow rates of the two air outlets 121, so as to more flexibly control the air outlet component 120.

[0039] In one embodiment, reference Figure 1 and Figure 3As shown, optionally, there are multiple air outlets 121, and multiple air outlets 121 correspond to one cylinder 110. Multiple air outlets 121 are respectively located on the circumference of the side wall of the accommodating cavity 111. Accordingly, multiple air outlets 121 are installed around the circumference of the side wall of the accommodating cavity 111. Blowing the same cylinder 110 through multiple air outlets 121 can increase the turbulence of the air flow, generate eddies or turbulence in the accommodating cavity 111, and improve the blowing effect on accumulated powder or powder clumps. In one embodiment, as Figure 1 As shown, the powder accumulation prevention device 100 optionally further includes a sealing member 150, which seals the opening of the accommodating chamber 111, thereby forming a sealed space within the accommodating chamber 111 and reducing the possibility of accumulated powder overflowing under the blowing action of the air outlet assembly 120, thereby polluting the working environment and affecting air quality. Furthermore, the sealing member 150 is a sealing plate that can be installed at the opening of the accommodating chamber 111.

[0040] Optionally, the seal 150 is provided with a discharge port 151, which is located between the air outlet assembly 120 and the dust removal assembly 130. The powder can be discharged through the discharge port 151 of the seal 150 to reduce the splashing or overflow of the powder from the opening of the accommodating chamber 111 during the falling process.

[0041] In summary, the anti-powder accumulation device 100 is used to discharge powder through the accommodating chamber 111 of the cylinder 110, and the air outlet component 120 can generate an air source, and the air outlet 121 of the air outlet component 120 blows air to the side wall of the accommodating chamber 111 of the cylinder 110, so that an air flow is generated in the accommodating chamber 111 of the cylinder 110, which is conducive to blowing away the water vapor in the accommodating chamber 111, and reducing the situation where powder accumulation on the side wall of the accommodating chamber 111 of the cylinder 110 is in the form of clumps under the action of water vapor. The dust removal component 130 can absorb powder or powder clumps with water vapor, and reduce the situation where powder overflows during the blowing process. When the air outlet component 120 is turned on, the dust removal component 130 is controlled to start by the control component 140, so as to achieve the purpose of making the air outlet component 120 and the dust removal component 130 work together to process the powder, reduce the situation where powder accumulation in the cylinder 110 affects the quality of the finished product, and thus improve the yield rate, with better technical effects.

[0042] Example 2

[0043] refer to Figures 1 to 3 As shown, an embodiment of the present application provides another device for preventing powder accumulation 100 , which includes at least a cylinder 110 , an air outlet assembly 120 , a dust removal assembly 130 and a control assembly 140 .

[0044] Specifically, if Figure 1As shown, the cylinder 110 is provided with a accommodating cavity 111. The air outlet assembly 120 is provided with a plurality of air outlets 121, and the air outlets 121 extend into the accommodating cavity 111. The blowing direction of the air outlet 121 is toward the side wall surface of the accommodating cavity 111, so that the air outlet 121 of the air outlet assembly 120 can generate an air flow passing through the air flow path. The dust removal assembly 130 includes a dust suction pipe 131, and the dust suction pipe 131 extends into the accommodating cavity 111. The dust suction port of the dust suction pipe 131 is located at one end of the air flow path of the air flow away from the air outlet 121. The control assembly 140 is electrically connected to the air outlet assembly 120 and the dust removal assembly 130 respectively.

[0045] It can be understood that when the air outlet component 120 is turned on, the control component 140 controls the operation of the dust removal component 130. Accordingly, the accommodating chamber 111 of the cylinder 110 is used to discharge the powder. The air outlet component 120 can generate an air source, and the air outlet 121 of the air outlet component 120 blows air to the side wall of the accommodating chamber 111 of the cylinder 110, so that an air flow is generated in the accommodating chamber 111 of the cylinder 110, which is conducive to blowing away the water vapor in the accommodating chamber 111, reducing the accumulation of powder on the side wall of the accommodating chamber 111 of the cylinder 110 and reducing the situation where the powder is lumped under the action of water vapor. The dust removal component 130 can absorb powder or powder lumps with water vapor, reducing the situation where powder overflows during the blowing process.

[0046] In this embodiment, when the air outlet assembly 120 is turned on, the dust removal assembly 130 is controlled by the control assembly 140 to start, so that the air outlet assembly 120 and the dust removal assembly 130 can work together to process the powder. The dust removal assembly 130 is used in conjunction with the air outlet assembly 120 to achieve the purpose of sucking away the accumulated dust entering through the dust removal assembly 130, thereby reducing the accumulation of powder in the cylinder 110 that affects the quality of the finished product, thereby improving the yield rate. In addition, when the air outlet assembly 120 is turned off, the control assembly 140 controls the dust removal assembly 130 to turn off, that is, when the air outlet assembly 120 stops running, the dust removal assembly 130 can be controlled by the control assembly 140 to stop running, thereby preventing the dust removal assembly 130 from accidentally sucking in the powder in the hopper when it is running alone, thereby reducing the accumulation of powder on the side wall of the accommodating chamber 111 of the cylinder 110.

[0047] In one embodiment, reference Figure 1 and Figure 2As shown, optionally, the number of the air outlets 121 of the air outlet component 120 is multiple, and the number of the cylinders 110 is multiple, and one air outlet 121 corresponds to one cylinder 110, that is, air is blown into the accommodating cavity 111 of a cylinder 110 through one air outlet 121 of the air outlet component 120, so that air flow is generated in the accommodating cavity 111, and powder accumulation on the side wall of the accommodating cavity 111 is reduced. The blowing operation can be performed on multiple cylinders 110 respectively through the multiple air outlets 121 of the air outlet component 120 to improve the blowing efficiency of the air outlet component 120.

[0048] Alternatively, as Figure 2 As shown, there are two air outlets 121, and the two air outlets 121 are in a "Y"-shaped structure. There are two cylinders 110, so that each air outlet 121 corresponds to one cylinder 110, that is, the two air outlets 121 branch out from a main channel to form a "Y"-shaped structure. The two air outlets 121 in the "Y"-shaped structure reduce the resistance when the air flow passes through, improve the air outlet efficiency, and the air flow in the air outlet component 120 can be diverted through the two air outlets 121 toward the two cylinders 110, and the two cylinders 110 can be blown at the same time. Of course, the air outlet component includes a blower, and the blower is connected to the two air outlets 121 respectively, so that the two air outlets 121 can also be set independently, so that the two air outlets 121 will not cause obstruction or influence on each other.

[0049] Optionally, the air outlet component is connected to a cold air source. Accordingly, the cold air source can be a blower or a cold air device. Since there is hot air in the cylinder 110, and powder clumps are easily generated and adhered to the side wall of the discharge cylinder under the action of water vapor, cold air can be sent into the cylinder 110 through the air outlet component through the cold air source, so that the cold air can be evenly mixed with the hot steam in the cylinder 110, thereby accelerating the flow of hot air, removing moisture from the material, and cooling the cylinder 110, thereby reducing the water vapor content in the cylinder 110, helping to discharge water vapor faster and improve dehumidification efficiency.

[0050] In one embodiment, Figure 1 As shown, optionally, the anti-powder accumulation device 100 also includes a seal 150, which closes the opening of the accommodating cavity 111 to form a sealed space in the accommodating cavity 111, thereby reducing the overflow of accumulated powder under the blowing action of the air outlet component 120, causing pollution to the working environment and affecting the air quality.

[0051] In one embodiment, optionally, the dust removal assembly 130 includes a bag-type dust collector, which is connected to the cylinder 110 through the dust suction pipe 131. The bag-type dust collector captures dust particles in the air, and the dust is trapped on the surface of the filter bag, and the purified gas is discharged through the filter bag to filter the accumulated dust in the air. It can capture relatively fine accumulated dust particles and has a better dust removal effect.

[0052] Optionally, the dust suction port of the dust suction pipe 131 is provided with a dust return prevention portion, which allows airflow to pass in one direction but automatically closes in the other direction to prevent gas or dust from flowing back, and is used to prevent accumulated dust from flowing back into the barrel 110 when the airflow stops or reverses. Exemplarily, the dust return prevention portion is a dust return prevention air nozzle, which can be a rubber flap type, a spring leaf type, or a ball valve.

[0053] Example 3

[0054] An embodiment of the present invention also provides a hopper device, including the anti-powder accumulation device 100 in Example 1 or Example 2. The hopper device including the anti-powder accumulation device 100 has all the beneficial effects of the anti-powder accumulation device 100, which will not be described in detail here.

[0055] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not limiting, and thus other examples of the exemplary embodiments may have different values.

[0056] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
