Description

The ultra-micro powder continuously trapping system
The utility model relates to a kind of device of collecting the ultra-micro powder of chemical gas phase reaction generation in vacuum system continuously.
Preparing the ultra-micro powder material with laser chemistry gas-phase reaction method or conventional chemical gas-phase reaction method, is the employed important method of current nano material preparation science frontier.The characteristics that this chemical gas-phase reaction method prepares ultra micro powder are: through chemical gas phase reaction, directly synthetic or generate solid-state ultra-micro powder, these powder are mingled in the remaining reacting gas and vector gas reacting gas, drift about with gas in vacuum chamber.Being used to carry the gas of these ultra-micro powders, is inert gas mostly
At present, the method for collecting these powder is to adopt filtering materials such as filter bag, filter membrane that powder is filtered out from vector gas, when the filtering material venting capability descends greatly, takes out filtering material again, removes the powder delivery end from filtering material, collects.This traditional method has two weak points, and when the first is collected ultra-micro powder from filtering material, filtering material will temporarily stop the capture of powder, and the gas-phase reaction of synthetic powder also will be forced to suspend, thereby this collection method is step; It two is filtering materials when capturing powder, and it sees through ability and constantly descends, and makes the procedure parameter of gas-phase reaction can not keep stable as pressure, flow etc., thereby has influenced the uniformity of granularity of the ultra-micro powder that generates and the uniformity of quality etc.
The purpose of this utility model is in order to address the above problem, to provide a kind of when preparing the ultra-micro powder material with laser chemistry gas-phase reaction method or conventional chemical gas-phase reaction method, the device of the collection ultra-micro powder of energy continous-stable.
For achieving the above object, solution of the present utility model is: be provided with one and rotate through filter cylinder and a rotating brushes in vacuum chamber, cartridge filter contacts with the hairbrush surface, the rotating filter jacket casing is connected on taking out in a fit of anger of vavuum pump, rotate through filter cylinder and rotating brushes, drive at the uniform velocity rotation by the outer electric system of vacuum chamber, there is air intake the side on vacuum chamber, and the inert gas that is loaded with ultra-micro powder from then on mouth enters vacuum chamber; There is the funnel-form outlet below, and the ultra-micro powder that is captured from then on mouth spills.
The utility model compared with prior art has following advantage: the collection process of a ultra-micro powder is continuous, stable, has improved efficient, has simplified operation; Two. in the chemical gas phase reaction of synthetic or generation ultra-micro powder, kept the relatively stable of air pressure and air flow value, thereby made the ultra-micro powder even particle size of generation, uniform quality.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model ultra-micro powder continuously trapping system structure chart;
Fig. 2 is the header structure figure that bleeds;
Fig. 3 is the rotary tube structure chart.
As shown in Figure 1, structure of the present utility model is: there are two holes on the top of vacuum chamber (1) in sealing, in rotating shaft (16) and (20) are arranged; The lower end of rotating shaft (16) is connected with rotary tube (5), and rotating brushes (4) is equipped with in the lower end of rotating shaft (20), and rotary tube (5) contacts with the surface of rotating brushes (4); The upper side of vacuum chamber (1) has the lower side of air intake (6) vacuum chamber (1) that L type exhaust tube (2) is arranged, and there is funnel-form outlet (3) lower end of vacuum chamber (1); Be connected with the head (21) of bleeding on the top of L type exhaust tube (2); Rotary tube (5) is socketed on the outer garden of the head (21) of bleeding.
As shown in Figure 2, the head (21) of bleeding is a garden cylindricality framework, and its upper base is a garden shape plate (7), and half of going to the bottom is that half garden shape plate (8) is sealed, and second half is the half garden bleeding point of opening (14); Garden shape plate (7) is linked to each other with support bar (13) by median septum (9) with half garden shape plate (8), and there are sealing side plate (10), (11) in the both sides of median septum (9); In the position relative with support bar (13) support bar (12) is arranged, it links to each other the garden ring (23) of garden shape plate (7) with head (21) lower end of bleeding; On the garden ring (23) " O " RunddichtringO groove (15) is arranged; Garden, the lower end ring (23) of head (21) of bleeding is connected the top of L type exhaust tube (2).
As shown in Figure 3, also a garden cylindricality framework in the rotary tube (5), its upper base also is a garden shape plate (17), there is garden ring (19) its lower end, in the middle of garden shape plate (17) and garden ring (19), have some thickness length to equate, and the support bar of equidistant arrangement (18) link to each other both; The center of garden shape plate (17) is connected in the lower end of rotating shaft (16); Covering on this garden cylindricality frame outer has suitable filtering material (22), and filtering material (22) can be film, cloth or sheet.
After in the seal groove (15) of head (21) of bleeding, loading onto O shape rubber seal (24), rotary tube (5) can be socketed on the outer garden of the head (21) of bleeding, at this moment, the garden ring (19) of rotary tube (5) lower end can closely cooperate with rubber seal (24), can allow rotary tube (5) rotate freely again; Simultaneously, rotating shaft (15), rotary tube (5) and head (21) totally one vertical center line of bleeding.
The course of work of the present utility model is: vavuum pump is by connecting together, and the rotary tube (5) of sealing and the head (21) of bleeding, via exhaust tube (2) with the extraction of the air in the vacuum chamber (1); The inert air-flow that carries ultra-micro powder enters vacuum chamber (1) through air intake (6), and simultaneously, electric system at the uniform velocity rotates by rotating shaft (16), (20) driven rotary garden tube (5) and rotating brushes (4); The head (21) of bleeding that is connected in L type exhaust tube (2) top is fixed, and half garden bleeding point (4) of its bottom is facing to the direction of air intake (6); The air-flow that carries ultra-micro powder is through rotary tube (5), half garden bleeding point (14) and exhaust tube (2), siphoned away by vavuum pump, and the filtering material (22) that ultra-micro powder is rotated on the garden tube (5) filters out from carrier gas stream, is adsorbed on the filtering material (22); When rotary tube (5) forwards second half to, by upper base garden shape plate (7), when going to the bottom the enclosed area that half garden shape plate (8) and median septum (9) constitute, because vavuum pump can not be bled in this zone, and make the absorption affinity of ultra-micro powder on filtering material (22) very little, at this moment, the rotating brushes that is rotating (4) just contacts with the filtering material (22) on the rotary tube that is rotating (5) surface, just like a cork the ultra-micro powder on the filtering material (22) is cleaned, spill vacuum chamber (1) through funnel-form outlet (3), and be collected; Above process moves in circles, and the collection work of ultra-micro powder is continuously carried out.
