It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

In order to explain the technical solution of the present invention, the following description is made by using specific examples.

The embodiment of the utility model provides an efficient metal material fluidizer, combine fig. 1, fig. 2 and fig. 3 to show, an efficient metal material fluidizer includes fluidization storehouse 10, rose box 20, extension board 22, flexible component 23, elastic component 24, strikes board 25 and actuating mechanism. The fluidizing chamber 10 is provided with an air inlet duct 11 and an air outlet duct 12 and is used for accommodating metal materials. The filter box 20 is vertically above the fluidization chamber 10, and a filter bag 21 is disposed in the chamber. The air outlet pipe 12 extends into the cavity of the filter box 20 and is connected with the opening end of the filter bag 21 in a sealing manner.

The support plate 22 is located within the cavity of the filter box 20 and is slidably connected to the side walls of the filter box 20. The flexible member 23 is connected at a first end to the strut 22 and at a second end to the filter bag 21 for vibrating the filter bag 21 as the strut 22 moves. The elastic element 24 is connected at a first end to a side wall of the filter box 20 and at a second end to the support plate 22 for driving the support plate 22 to move in a compressed state. The striking plate 25 is located within the cavity of the filter box 20 and is used to drive the support plate 22 to move when the support plate 22 is struck. The driving mechanism is connected to the striking plate 25 and is used for driving the striking plate 25 to reciprocate.

After the air current enters the fluidization bin 10 along the air inlet pipe 11, the metal material in the fluidization bin 10 enters a fluidization state, and the gas discharged from the fluidization bin 10 enters the filter bag 21 along the air outlet pipe 12. The filter bag 21 plays a role in filtering, and metal dust entrained in the air flow is retained on the filter bag 21.

The driving mechanism drives the striking plate 25 to reciprocate. When the striking plate 25 strikes the support plate 22, the support plate 22 is moved, at which point the elastic element 24 is compressed; after the knocking plate 25 moves reversely and is separated from the support plate 22, the elastic element 24 drives the support plate 22 to reset, so that the knocking plate 25 is matched with the elastic element 24 to realize the reciprocating movement of the support plate 22.

The support plate 22 drives the flexible element 23 to shake, and the flexible element 23 drives the filter bag 21 to shake, so that metal dust attached to the filter bag 21 can be shaken off. Because the first end of the filter bag 21 is connected with the air outlet pipe 12 in a sealing manner, and the filter bag 21 is positioned above the air outlet pipe 12 in the vertical direction, the shaken-off metal dust can return to the fluidized chamber 10 along the air outlet pipe 12, thereby realizing the recycling of metal materials in the waste gas.

If the fluidization storehouse 10 sets up to pressure vessel, then need customize according to pressure vessel's requirement during processing, corresponding laboratory also need be rebuild into explosion-proof room, and relevant pipeline need be changed into explosion-proof pipeline, and is corresponding, and the experiment cost can increase, consequently, fluidization storehouse 10 is the ordinary pressure container in this embodiment.

In the experiment, gas is introduced into the fluidization bin 10, so that the metal material enters a fluidization state under the action of the gas flow, and therefore, the air outlet pipe 12 is required to be arranged for maintaining the normal-pressure environment in the fluidization bin 10. The exhaust gas in the air outlet pipe 12 carries metal dust, and if the exhaust gas is directly discharged to the external environment, environmental pollution and experimental materials waste. Therefore, the filter bag 21 is provided in the present embodiment.

When the air inlet pipe 11 is opened, airflow is blown into the filter bag 21 along the air outlet pipe 12, the filter bag 21 is expanded under the action of the airflow (similar to the process of blowing a balloon), and the driving mechanism is kept static at the moment; when the air inlet pipe 11 is closed, the filter bag 21 is in a natural state, i.e. a bag shape, due to no air flow effect, the projection of the filter bag 21 in the horizontal plane falls into the pipe opening of the air outlet pipe 12, when the driving mechanism drives the knocking plate 25 to reciprocate, the support plate 22 drives the filter bag 21 to shake through the flexible element 23 under the action of the knocking plate 25 and the elastic element 24, and the shaken metal dust can fall into the air outlet pipe 12 and slide into the fluidization bin 10.

In the experiment process, the fluidization process in the fluidization bin 10 and the shaking-off process of the filter bag 21 are alternately carried out, so that the utilization rate of experiment materials is improved, and the waste of metal materials is avoided. In addition, the materials shaken off the filter bag 21 return to the fluidization bin 10 again and do not separate from the fluidization device, so that the uniformity of the materials in one experiment can be ensured.

Among the prior art, even with the material recovery in the waste gas, because the material of retrieving has broken away from fluidizer, for avoiding cross contamination, can't add fluidization storehouse 10 again in, consequently, the material of retrieving also can have the difference with the experimental material, can't utilize simultaneously, consequently, still can cause the waste of experimental material, especially to the fluidization experiment of noble metal, especially can waste expensive experiment cost.

In the fluidizing device provided in this embodiment, the filter bag 21 is directly communicated with the fluidizing chamber 10, and the material on the filter bag 21 is not separated from the fluidizing system of the fluidizing chamber 10, so that the problem of cross contamination does not exist. Specifically, the air inlet pipe 11 is opened for 3 to 5 minutes and then closed, and then the driving mechanism is opened for 1 to 2 minutes. The fluidization process in the fluidization storehouse 10 and the shake-off process of filter bag 21 are carried out in turn, when the adnexed metal material on recycle filter bag 21, can make the fluidization time of experimental material tend to unanimous to guarantee experimental material's homogeneity, promptly: the metal particles have uniform particle size and regular shape.

Specifically, the filter bag 21 is located above the air outlet pipe 12. Specifically, the flexible element 23 may be a spring, or may be an elastic string. Specifically, the filter bag 21 may be a woven PTFE + PTFE coated filter bag produced by siqiang environmental protection equipment ltd, or a filter bag for metallurgical industry produced by okkai environmental protection technology ltd.

Specifically, the pore size of the filter bag 21 is determined according to the particle size of the metal particles. Specifically, the opening end of the filter bag 21 is sleeved on the air outlet pipe 12 and connected by a clamp. Because the flexible element 23 and the filter bag 21 are flexibly deformed, when the support plate 22 reciprocates, the filter bag 21 can shake, and dust attached to the filter bag 21 can be shaken off.

Specifically, the elastic member 24 may be a compression spring. The elastic member 24 can enhance the shake strength of the flexible member 23 and prolong the inertial shake time of the flexible member 23, thereby enhancing the shake-off effect.

The output shaft of the rapping motor 264 is connected to the second end of the crank 263 and is used to drive the crank 263 in rotation.

If the driving mechanism adopts the air cylinder, an air source needs to be additionally arranged during the experiment, and the experiment difficulty is increased. If the driving mechanism adopts a transmission structure of a gear and a rack, a motor capable of rotating forwards and reversely needs to be configured, and controllers such as a PLC or a single chip microcomputer need to be configured, so that the purchase cost and the control difficulty are increased. Therefore, the transmission structure of the crank block is adopted in the embodiment, an air source does not need to be configured, the cost is low, and the operation is convenient.
