Description

Technical Field

[0001] The present invention relates to the technical field of elutriation devices, and specifically to an elutriation device based on powder particle separation and its usage method. Background Art

[0002] Elutriation refers to a method of discharging while fine powder particles and air or water flow simultaneously, that is, the operation of powder classification is called elutriation. Using this principle, powder samples can be classified or particle size measurement can be carried out. An elutriator is a powder separation device mainly used for the separation of tiny crystal grains and fiber dust in granular products. It utilizes the velocity difference existing between the gas-solid two-phase in each region, so that the fine dust attached to the surface of the granular material falls off due to the shearing action of the gas on the solid surface. When the air flow suddenly accelerates, decelerates or changes direction, the air flow boundary layer bypassing the surface of the granular material needs to be re-established. At this time, the shearing force of the air flow on the surface of the granular material increases several times. During operation, the solid granular material entering the device goes through the acceleration and deceleration stages. Under the shearing action of the air flow, the thick and fine granular materials are separated. The finished granular material falls into the silo, and the fine dust is discharged outside the device with the air flow, so as to achieve the purpose of elutriation and cleaning. However, there are still certain deficiencies in the actual use of the elutriation device in the prior art. For example:

[0003] The elutriation device in the prior art cannot effectively eliminate the electrostatic force between powder particles, which greatly limits the powder particles during the dust separation operation, thereby reducing the powder particle separation effect. As a result, due to the electrostatic effect, the separated powder particles will be re-contaminated after dust separation, greatly reducing the powder particle separation effect, so it cannot meet the requirements of the prior art. Summary of the Invention

[0004] The purpose of the present invention is to provide an elutriation device based on powder particle separation to solve the problems put forward in the above background art.

[0007] Preferably, the transfer pipe further includes a heating wire. The heating wire is fixedly connected to the inner wall of the transfer pipe near one end by bolts. The heating wire is electrically connected to an external power supply and is electrically connected to the control device.

[0008] Preferably, the bottom cover further includes a condensation plate. The condensation plate is fixedly connected to the inner wall of the bottom cover near the bottom end of the adjacent surface of the conveying pipe by bolts. The four ends of the periphery of the condensation plate penetrate through the bottom cover. The condensation plate is fixedly connected to the output end of an external condenser by bolts.

[0009] Preferably, the condensation plate further includes a condensation pipe. The condensation plate is disc-shaped. The outer ring of the condensation plate is cross-shaped. Condensation pipes are inserted into the four ends of the middle of the periphery of the condensation plate. The periphery of the condensation pipe is fixedly connected to the condensation plate by bolts. The condensation pipe is fixedly connected to the output end of an external condenser by bolts.

[0010] Preferably, the condensation pipe further includes a limiting ring. The limiting ring is fixedly connected to the flange by bolts near the bottom cover on the periphery of the condensation pipe. One side of the limiting ring is fixedly connected to the bottom cover by bolts. The limiting ring is used as a limiting device for the condensation pipe outside the bottom cover.

[0011] Preferably, the bottom cover further includes a support seat. Brackets are fixedly connected to the four sides of the lower surface of the inner wall of the bottom cover near the bottom end by bolts. The tops of the four brackets are fixedly connected to the support seat by bolts. A support column is inserted into the middle of the top of the support seat. A return spring is welded to the bottom end of the support column. The bottom end of the return spring is welded to the lower surface of the inner wall of the support seat. The top of the support column is fixedly connected to a support plate by bolts. The upper surface of the support plate is in the same plane as the bottom end of the conveying pipe.

[0012] Preferably, a support shaft is fixedly connected to the middle of the upper surface of the support plate by bolts. A spiral blade is fixedly connected to the top of the support shaft by bolts. The spiral blade is located inside the conveying pipe.

A protective pad is pasted on the lower surface of the support plate.

[0014] Preferably, a method for using an elutriation device based on the powder separation effect includes the following steps:

[0015] S1. First, electrically connect this elutriation device to an external power supply system through a signal connection terminal, so that this elutriation device can continuously obtain electrical energy. Then, control the buffer hopper through a rotary blanking valve, so that the powder and granular materials to be elutriated can be put through the buffer hopper and transmitted through the through holes inside the mounting seat and the fixed seat, so that the powder and granular materials to be elutriated can smoothly enter the conveying pipe inside the top cover and the bottom cover for transmission;

[0016] S2. Then, connect the conveying pipe to the wind power output end of an external fan, so that the wind power transmitted by the external fan can be transmitted into the conveying pipe through the connecting pipe and the fixing part, and heated by the heating wire inside the conveying pipe, so that the wind power sent into the inside of the conveying pipe can effectively dry, heat and remove static electricity from the powder and granular materials inside the conveying pipe during circulation. And by providing a plug plate in the fixing part, it can effectively cut off the wind power of the conveying pipe, the fixing part and the connecting pipe, so as to further achieve the effect of intermittently conveying the wind power during the closed treatment of the inside of the conveying pipe;

[0017] S3. Install the spiral blade on the support plate through the support shaft, so that the wind power conveyed through the conveying pipe can effectively rotate the spiral blade when intermittently conveyed through the plug plate, thereby further promoting the support plate to displace towards the side away from the bottom end of the conveying pipe, so that the powder and granular materials at the bottom end of the conveying pipe can fall on the upper surface of the support plate. And through the condensation plate and the condensation pipe provided on the inner wall of the bottom cover, the periphery of the powder and granular materials is condensed during the falling process, so that the dust on the periphery of the powder and granular materials is separated and output through the discharge port at the bottom end of the bottom cover.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The present invention can effectively control the feeding rate of the materials transported into the internal part of this elutriation device through a rotary blanking valve provided in a buffer hopper above the mounting base, so that the fed materials can pass through the transmission pipes provided on both sides of the top cover and the bottom cover when dust separation processing is carried out through this elutriation device. The transmission pipes are connected to the connecting pipes through fixing parts, and the air flow inside the transmission pipes is controlled by a plug board. Thus, when the user conveys wind into the internal part of this elutriation device through the transmission pipes and heats it through a heating wire, static electricity of the materials put into the internal part of this elutriation device can be effectively removed. Therefore, when powder particles are separated and processed, secondary contamination between dusts can be effectively avoided, thereby effectively improving the dust separation effect. And through a support seat provided by a support in the bottom cover and a reset spring provided between the support seat and the support column, and a support plate provided at the top end of the support column and a spiral blade provided above the support plate, the spiral blade can further increase the displacement of the support plate towards the end far away from the conveying pipe, so that the separated powder particles can be peripherally liquefied through a condensation plate and a condensation pipe after dust separation, and thus the dust after electrostatic separation can be effectively removed from the liquefied dust, further improving the powder particle separation effect and effectively making up for the deficiencies in the prior art.

Then connect the transfer pipe 3 to the wind power output end of the external fan, so that the wind power transmitted by the external fan can be conveyed into the transfer pipe 3 through the connecting pipe 34 and the fixing part 32, and heated by the heating wire 31 in the transfer pipe 3. When the wind power sent into the inside of the conveying pipe 22 circulates, it can effectively dry, heat and remove static electricity from the powder and granular materials inside the conveying pipe 22 during transportation. And by providing a plug board 33 in the fixing part 32, it can effectively cut off the wind power of the transfer pipe 3, the fixing part 32 and the connecting pipe 34, so as to further achieve the effect of intermittently conveying the wind power for transportation while closing the inside of the conveying pipe 22;

[0037] S3. Install the spiral blade 46 on the support plate 44 through the support shaft 45, so that when the wind power conveyed through the transfer pipe 3 is intermittently conveyed through the plug board 33, the spiral blade 46 can be effectively rotated, which further prompts the support plate 44 to displace towards the side away from the bottom end of the conveying pipe 22, so that the powder and granular materials at the bottom end of the conveying pipe 22 can fall on the upper surface of the support plate 44. And by providing a condensation plate 23 and a condensation pipe 24 on the inner wall of the bottom cover 21, the periphery of the powder and granular materials can be condensed during the falling process, so that the dust on the periphery of the powder and granular materials can be separated and output through the discharge port 26 at the bottom end of the bottom cover 21.
