In addition, the terms "first", "second", "third", and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0034] The embodiments of the present application will be described below in connection with Figures 1-2 The utility model will be described in detail.

[0035] A carbon powder powder collector, including the shell that is equipped with collection cavity 1 in, the collection cavity 1 includes separation part and the collection part that is arranged below separation part, separation membrane 6 is arranged in the separation part in the filter mechanism including the separation part, the shell is provided with feed inlet 8 and air outlet 5 with separation membrane 6 opposite place, the collection part is provided with carbon powder outlet 2.

[0036] In the embodiment, the feed inlet 8 and the air outlet 5 are staggered up and down.

[0037] In the embodiment, the separation membrane 6 is of annular structure. Since the separation membrane 6 is movable, the separation membrane 6 is arranged in annular structure, and the separation membrane 6 can still be opposite to the feed inlet 8 after being moved, ensuring the purification effect.

[0038] The filter mechanism comprises a driving part, a transmission part is connected to the driving part, and the transmission part is connected to the separation membrane 6.

[0039] In this embodiment, the transmission part comprises a rotating shaft 3, the two ends of the rotating shaft 3 are movably connected to the separation part, and the separation membrane 6 is arranged on the rotating shaft 3; the driving part comprises a first motor 4, and the output end of the first motor 4 is connected to the end of the rotating shaft 3.

[0040] In this embodiment, a mounting frame 7 is further included, and the transmission part is connected to the separation membrane 6 through the mounting frame 7. The mounting frame 7 can ensure the shape of the separation membrane 6 and prevent the separation membrane 6 from being deformed.

[0041] In this embodiment, the separation part is a cylindrical cavity, the collecting part is a conical cavity, the connecting part of the collecting part and the separation part has the same diameter, the diameter of the collecting part gradually decreases from one end connected to the separation part to the other end, and the carbon powder outlet 2 is arranged at the lowest position of the collecting part. The carbon powder falling from the separation part can be collected into the carbon powder outlet 2 by arranging the collecting part in a conical structure, and the carbon powder can be easily discharged from the carbon powder outlet 2.

[0042] In this embodiment, the separation membrane 6 is a metal ion membrane, and the pore size thereof is equal to 100 nm. Since the carbon powder has ions under a high-temperature environment, and most of the carbon powder has a particle size less than 100 nm, the separation membrane 6 can be a metal ion membrane with a pore size greater than or equal to 100 nm. Since the pore size of the metal ion membrane is greater than the particle size of the carbon powder, and the carbon powder has ions under a high-temperature environment, the charged carbon powder can be adsorbed on the metal ion membrane made of metal material through electrostatic action, that is, when a charged object approaches a metal object, electrostatic induction occurs in the metal object, causing free electrons in the object to move to the surface, so that the surface is in a charged state. Therefore, the potential generated by electrostatic induction and the electrostatic of the charged object are attracted to each other under the action of Coulomb force, so that adsorption occurs. Therefore, the charged carbon powder can be first adsorbed by the metal ion membrane, and hydrogen gas passes through the pores of the metal ion membrane and is discharged.

[0043] The specific use method of the utility model is as follows:

[0044] Refer to Figure 1When the mixed gas of hydrogen and toner enters the housing through the feed port 8, it first contacts the separation membrane 6 in the separation section. The toner is adsorbed by the separation membrane 6, while the hydrogen can be discharged from the outlet 5. By setting the mounting bracket 7 on the rotating shaft 3, the output end of the first motor 4 is connected to the end of the rotating shaft 3. Specifically, the first motor 4 can be a servo motor. Since the speed and position accuracy of the servo motor are very accurate, the driving force can be transmitted to the rotating shaft 3 by controlling the forward or reverse rotation of the servo motor, thereby driving the rotating shaft 3 to rotate forward or reverse in a regular manner. Since the mounting bracket 7 is set on the rotating shaft 3, the rotating shaft 3 can drive the mounting bracket 7 to move regularly (i.e., forward or reverse), thereby making it easier to shake off the nano-sized toner adsorbed on the separation membrane 6, thus completing the collection of nano-sized toner.

[0045] Example 2

[0046] like Figure 2 As shown, this embodiment is basically the same as embodiment 1, except that the transmission part includes a lead screw 31' and a lead screw nut 32' that are mutually driven and cooperate with each other. The two ends of the lead screw 31' are respectively movably connected to the separation part, and the separation membrane 6 is disposed on the lead screw nut 32'. The drive part includes a second motor 4', and the output end of the second motor 4' is connected to the end of the lead screw 31'. By setting the mounting bracket 7 on the lead screw nut 32', and connecting the output end of the second motor 4' to the end of the lead screw 31', the second motor 4' can be a servo motor. Since the speed and position accuracy of the servo motor are very accurate, the driving force can be transmitted to the lead screw 31' by controlling the forward or reverse rotation of the servo motor, thereby driving the lead screw 31' to rotate forward or reverse in a regular manner. Since the lead screw nut 32' and the lead screw 31' are connected by a threaded engagement, the lead screw nut 32' can be driven to reciprocate along the direction of the lead screw 31'. Since the mounting bracket 7 is set on the lead screw nut 32', it can be driven to move regularly (i.e., reciprocate), thereby making it easier to shake off the nano-sized carbon powder adsorbed on the separation membrane 6, thus completing the collection of nano-sized carbon powder.

[0047] Example 3

[0048] like Figure 1 As shown, in order to completely collect the nano-carbon powder on the separation membrane 6, this embodiment further improves upon embodiment 1 by including an air supply component in the carbon powder collection device.

The air flow generated by the air blower 901 is sprayed into the collection cavity 1 through the scattering nozzle 902, so that the air flow is generated in the collection cavity 1, and the nanometer carbon powder adsorbed on the separation membrane is blown into the collection cavity 1 through the air flow, thereby achieving the technical effect of completely collecting the nanometer carbon powder on the separation membrane.

[0050] In order to further completely collect the nanometer carbon powder on the separation membrane, the scattering nozzle 902 is preferably provided with a plurality of spray ports. The air flow generated by the plurality of spray ports completely covers the separation membrane 6. Specifically, the included angle between the center line of the plurality of spray ports in the upper region of the scattering nozzle 902 and the horizontal line is arranged in a range, so that the coverage area of the air flow sprayed by the plurality of spray ports in the upper region can cover the upper region of the separation membrane 6. The included angle between the center line of the plurality of spray ports in the middle region of the scattering nozzle 902 and the horizontal line is arranged in a range, so that the coverage area of the air flow sprayed by the plurality of spray ports in the middle region can cover the middle region of the separation membrane 6. The included angle between the center line of the plurality of spray ports in the lower region of the scattering nozzle 902 and the horizontal line is arranged in a range, so that the coverage area of the air flow sprayed by the plurality of spray ports in the lower region can cover the lower region of the separation membrane 6.

[0051] In the embodiment, the coverage area of the air flow generated by the plurality of spray ports on the scattering nozzle 902 can completely cover the separation membrane 6, so that the air flow can be blown to each position on the separation membrane 6 through the spray ports, thereby further blowing all the nanometer carbon powder on the surface of the separation membrane 6 into the collection cavity 1, thereby achieving the technical effect of further completely collecting the nanometer carbon powder on the separation membrane 6.

[0052] In order to accurately guide the air flow generated by the air blower to the scattering nozzle, the air supply assembly further includes an air inlet pipeline 310, and the air blower 901 is communicated with the scattering nozzle 902 through the air inlet pipeline 310.

[0053] In the embodiment, the air blower 901 and the scattering nozzle 902 are communicated through the air inlet pipeline 310, and the air flow generated by the air blower can be accurately guided to the scattering nozzle through the air inlet pipeline 310.

It should be noted that, for ordinary skilled persons in the art, without departing from the technical concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application.
