Description

Technical Field

[0001] The present application relates to the field of dust removal in powder processing, and in particular to a circulation system for powder processing. Background Art

[0002] Existing powder processing equipment is directly connected to the external space, and a large amount of dust is easily generated during the processing of powder materials. This dust will escape into the environment, which not only causes waste of powder materials but also easily causes environmental pollution. In addition, powder materials usually have a water content limit. Existing powder processing equipment will cause the powder materials to come into direct contact with the air and absorb moisture, which will affect the quality of the powder materials. Utility Model Content

[0003] In view of this, the purpose of the present application is to provide a circulation system for powder processing equipment to solve the problem that existing powder processing equipment may cause powder material to escape or deteriorate in quality.

[0004] In accordance with the above objectives, the present invention provides a circulation system for powder processing, wherein the circulation system for powder processing comprises:

[0005] Circulation equipment, equipped with a blowing device and a gas-solid separator;

[0006] A pipeline assembly, through which the air blowing device, the powder processing equipment and the gas-solid separator are connected end to end in sequence; and

[0007] The valve assembly is connected to the pipeline assembly and the circulation equipment.

[0008] Preferably, the pipeline assembly includes a first branch pipe, and the outlet end of the blowing device is connected to the inlet end of the powder processing equipment through the first branch pipe.

[0009] Preferably, a first air outlet and a second air outlet are formed at the outlet end of the air blowing device, and the first air outlet is connected to the powder processing equipment through the first branch pipe.

[0010] Preferably, the second air outlet is provided with an exhaust valve, and the second air outlet is connected to a dust removal device.

[0011] Preferably, an air volume valve is provided on the first branch pipe, and the air volume valve is communicatively connected with the blowing device; the air volume valve and the blowing device can adjust the pipeline assembly to form a negative pressure state.

[0012] Preferably, the first branch pipe is further provided with an air supply valve, and the air supply valve is located between the air volume valve and the powder processing equipment.

[0013] Preferably, a humidity sensor is provided at the air outlet pipe of the air blowing device, and the humidity sensor is communicatively connected with the air supply valve.

[0014] Preferably, the gas-solid separator is provided with a pulse backflush valve.

[0015] Preferably, the pipeline assembly includes a second branch pipe, and both ends of the second branch pipe in the length direction are respectively connected to the outlet end of the powder processing equipment and the inlet end of the gas-solid separator.

[0016] Preferably, the pipeline assembly includes a third branch pipe, and both ends of the third branch pipe in the length direction are respectively connected to the outlet end of the gas-solid separator and the inlet end of the blowing device.

[0017] According to the circulation system for powder processing equipment of the present invention, the air blowing device, the powder processing equipment, and the gas-solid separator are sequentially connected end to end via a piping assembly to form a loop. Therefore, dust generated during the powder processing process does not escape into the air. Instead, it is first filtered by the gas-solid separator, and the filtered gas enters the air blowing device for continued circulation. This effectively prevents environmental pollution and deterioration of powder material quality caused by dust escape.

[0018] In addition, the circulation system is also provided with a valve assembly, through which the circulation of the gas can be flexibly controlled.

[0023] The following detailed description is provided to help the reader gain a comprehensive understanding of the methods, devices, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, except for operations that must occur in a particular order, changes may be made that will be apparent upon understanding the disclosure of this application. Furthermore, descriptions of features known in the art may be omitted for clarity and brevity.

[0024] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways to implement the methods, devices, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0025] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, it may be directly “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on,” “directly connected to,” “directly coupled to,” “directly over,” or “directly covering” another element, there may be no other elements intervening therebetween.

[0026] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0027] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are used only to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Thus, a first member, component, region, layer, or portion in the examples described herein may also be referred to as a second member, component, region, layer, or portion without departing from the teachings of the examples.

[0028] For ease of description, spatial relational terms such as "above," "upper," "below," and "lower" may be used herein to describe the relationship of one element to another element as shown in the accompanying drawings. Such spatial relational terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, an element described as being "above" or "upper" relative to another element would subsequently be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientations "above" and "below," depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly.

In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0032] The utility model provides a circulation system for powder processing, such as Figure 1 As shown, the circulation system for powder processing in this embodiment includes a circulation device, a piping assembly, and a valve assembly. The piping assembly connects the circulation device to the powder processing device 11 to form a loop, while the valve assembly allows for flexible control of gas circulation. The specific structure of each of the above components of the circulation system for powder processing according to the present invention (hereinafter referred to as the circulation system) will be described in detail below.

[0033] In this embodiment, the circulation equipment includes an air blowing device 12 and a gas-solid separator 13. The air blowing device 12 can be set as a variable frequency high-pressure blower. Both the air blowing device 12 and the gas-solid separator 13 are existing devices, so their structures and working principles are not described in detail. Furthermore, the air blowing device 12 and the gas-solid separator 13 are respectively located at the inlet and outlet ends of the powder processing equipment 11, that is, the air blowing device 12, the powder processing equipment 11 and the gas-solid separator 13 are connected end to end in sequence through the following pipeline components to form a loop, thereby effectively avoiding the quality degradation of the powder material due to contact with air, and can effectively avoid the waste of powder material due to escape.

[0034] Specifically, if Figure 1 As shown, the pipeline assembly includes a first branch pipe 21. The outlet end of the blowing device 12 is formed with a first air outlet 121 and a second air outlet 122. The first air outlet 121 is connected to the powder processing equipment 11 through the first branch pipe 21. The inlet end of the powder processing equipment 11 is formed with a feed port and an air inlet for introducing powder material, and the first branch pipe 21 is connected to the air inlet. In other words, the first branch pipe 21 connects the first air outlet 121 and the air inlet, thereby achieving communication between the blowing device 12 and the powder processing equipment 11. Furthermore, an exhaust valve 31 is provided at the second air outlet 122, and the second air outlet 122 is correspondingly connected to the dust removal equipment.

[0035] Furthermore, the first branch pipe 21 is provided with an air volume valve 32, which is in communication with the air blowing device 12. By comprehensively regulating the opening of the air volume valve 32 and the frequency of the air blowing device 12, a negative pressure state can be created inside the powder processing equipment 11, effectively preventing dust from escaping. Furthermore, the first branch pipe 21 is provided with an air supply valve 33, which is located between the air volume valve 32 and the powder processing equipment 11. A humidity sensor 35 is installed at the outlet line of the air blowing device 12. The humidity sensor 35 is in communication with the air supply valve 33, and the air supply valve 33 can be opened or closed based on the humidity value fed back by the humidity sensor 35 to ensure that the moisture content of the powder material is within the standard range.

[0036] Furthermore, the gas-solid separator 13 is provided with a pulse back-blow valve 34. According to PV=nRT, in this circulation system, the gas generated by the introduction of powder material or the air supply of the air supply valve 33 or the pulse back-blow valve 34 can enter the dust removal equipment through the above-mentioned exhaust valve 31 (not released in the figure) to maintain the balance of the system.

[0037] In addition, the pipeline assembly also includes a second branch pipe 22 and a third branch pipe 23. The two ends of the second branch pipe 22 in the length direction are respectively connected to the outlet end of the powder processing equipment 11 and the inlet end of the gas-solid separator 13; the two ends of the third branch pipe 23 in the length direction are respectively connected to the outlet end of the gas-solid separator 13 and the inlet end of the blowing device 12.

[0038] According to the circulation system for the powder processing equipment 11 of the present invention, the blowing device 12, the powder processing equipment 11, and the gas-solid separator 13 are sequentially connected end to end via a piping assembly to form a loop. As a result, dust generated during the powder processing process does not escape into the air. Instead, it is first filtered by the gas-solid separator 13, and the filtered gas enters the blowing device 12 for continued circulation. This effectively prevents environmental pollution and deterioration of powder material quality caused by dust escape.

[0039] In addition, the circulation system is also provided with a valve assembly, through which the circulation of the gas can be flexibly controlled.

[0040] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The scope of protection of the present application is not limited thereto.
