Description

Technical Field

[0001] The invention belongs to the technical field of silicon micropowder production, and specifically refers to a production device for surface modification of silicon micropowder. Background Art

[0002] In the field of modern materials science and industrial applications, silicon micropowder, as an important inorganic non-metallic material, has broad application prospects in many industries such as electronics, chemicals, building materials, aerospace, etc. due to its unique physical and chemical properties, such as high hardness, high melting point, low thermal expansion coefficient and good insulation. However, the surface of unmodified silicon micropowder has defects such as fewer active groups, strong hydrophilicity and high surface energy, which greatly limits its further application in high-end fields such as organic-inorganic composite materials.

[0003] The existing silicon micropowder modification production equipment has exposed many problems during actual operation: (1) Part of the modifier and silicon micropowder will inevitably adhere to the side wall of the cylinder during the mixing process. As the production process continues, the adhesion layer will gradually thicken. On the one hand, this will cause material waste and reduce the effective utilization rate of the modifier and silicon micropowder. On the other hand, it is extremely difficult to clean these materials adhering to the side wall when the production batches are switched or the equipment is maintained; (2) In addition, when discharging, the silicon micropowder that is completely mixed and modified is collected and discharged together with the silicon micropowder that is unqualified due to agglomeration, which makes it difficult to treat the product in a targeted manner during subsequent processing. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the existing modification device easily causes the raw materials to adhere to the processing cylinder wall when in use, which is inconvenient to clean and affects the processing efficiency. In addition, it is inconvenient to separate the materials when discharging, which easily causes some agglomerated silicon micropowder to be mixed in the product, which is not conducive to subsequent processing.

[0005] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: a production device for surface modification of silicon micropowder, including a base plate, a modification cleaning mechanism arranged on the base plate, and a separation and collection mechanism connected to the modification cleaning mechanism; the modification cleaning mechanism includes a support frame and a motor 1, the support frame is arranged on the base plate, a modification cylinder is installed on the support frame, a cleaning assembly is arranged on the side wall of the modification cylinder, the motor 1 is arranged on the top of the modification cylinder, and an agitator is arranged at the output end of the motor 1.

[0006] Furthermore, the cleaning assembly includes a slide groove and a second motor, the slide groove is arranged on the side wall of the modified cylinder, a rotating ring is rotatably provided in the slide groove, a gear ring is provided on the inner side wall of the rotating ring, a connecting plate is provided at the bottom of the rotating ring, a cleaning brush is provided on the connecting plate, the cleaning brush is arranged close to the side wall of the modified cylinder, the second motor is installed on the top of the modified cylinder, a gear is provided at the output end of the second motor, and the gear is meshed with the gear ring.

[0007] Preferably, the slide groove is arranged in a closed ring shape.

[0008] Furthermore, a ring tube is installed on the top of the modification cylinder, a nozzle is passed through the bottom of the ring tube, and a feed pipe is also connected to the ring tube.

[0009] Furthermore, the separation and collection mechanism includes a drop pipe and a conveying pipe. The drop pipe is arranged through the bottom of the modification cylinder. One end of the conveying pipe is fixedly connected to the bottom of the drop pipe. The conveying pipe is fixedly installed on a support frame. The other end of the conveying pipe is provided with a discharge pipe. The bottom of the conveying pipe is evenly distributed with sieve holes.

[0010] Preferably, a motor three is installed on the side wall of one end of the conveying pipe, a driving shaft is provided at the output end of the motor three, the driving shaft is rotatably arranged in the conveying pipe, and a conveying auger is provided on the driving shaft.

[0011] Preferably, a collecting box and a separating box are placed on the bottom plate, the collecting box is placed below the sieve holes, and the separating box is placed below the discharge pipe.

[0012] The present invention adopts the above structure to achieve the following beneficial effects:

[0013] 1. By setting the slide groove and the gear ring, in conjunction with the second motor and the gear, the rotating ring can be driven to rotate, and the connecting plate can be driven to rotate, so that the cleaning brush can clean the side wall of the modified cylinder, which can effectively avoid the accumulation of silicon micropowder and modifier;

[0014] 2. By setting up conveying pipes and conveying auger, materials can be transported to avoid blockage during discharging. At the same time, with the sieve holes, the mixed materials can be screened to separate the completely mixed and qualified modified silicon micropowder from the unqualified modified silicon micropowder due to agglomeration, which is convenient for subsequent targeted processing.

The motor 5 is started to drive the stirrer 8 to stir the silicon micropowder, and the modifier is introduced into the feed pipe 18, and enters the annular tube 16 and is sprayed out through the nozzle 17 to mix with the silicon micropowder. The cleaning component 7 is started to clean the raw materials adhering to the side wall of the modification tube 6. At the same time, other conditions in the modification process, such as temperature, humidity and other adjustment structures are all existing technologies and will not be repeated again. After the modification is completed, the separation and collection mechanism 3 is started to separate and discharge the modified materials.

[0025] like Figure 4 and 6 As shown, the cleaning assembly 7 includes a slide 9 and a second motor 10. The slide 9 is arranged on the side wall of the modified cylinder 6.
