Novel preparation method and system for hydrophobic silica micropowder

Abstract

This invention relates to the field of hydrophobic silicon micropowder technology, and discloses a novel preparation method and system for hydrophobic silicon micropowder. The system includes a heating chamber, with a heating cavity and a drying cavity inside the heating chamber. A heat insulation plate is placed between the heating cavity and the drying cavity. A heating assembly is installed inside the heating cavity, and a feed inlet is provided at the top of the heating chamber. By placing the prepared silicon micropowder, water, and ethanol solution into the inner cavity of a container, the motor is started via a PLC control panel.

This makes the manufacture of hydrophobic silicon micropowder more convenient and suitable for widespread application.

Description

Technical Field

[0001] This invention belongs to the field of hydrophobic silica powder technology, specifically, it relates to a novel preparation method and system for hydrophobic silica powder. Background Technology

[0002] The production of plastics and rubber requires a large amount of fillers to improve their physical properties. At the same time, fillers play a crucial role in reducing costs. Silica micropowder tailings powder, with a particle size of 0.1-0.4μm, meets the requirements for rubber and plastic fillers. Modified silica micropowder, used as a filler in the preparation of rubber and plastic products, can reduce the cost of rubber and plastic products, improve their mechanical and electrical properties, and solve the environmental pollution and resource waste problems caused by tailings accumulation, truly turning waste into treasure.

[0003] However, existing methods for manufacturing hydrophobic silica powder often require heating followed by drying. But heating and drying are often separated during the manufacturing process, which means that the heated hydrophobic silica powder must be cooled before drying, making the process rather cumbersome.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A novel preparation system for hydrophobic silica micropowder includes a heating box, the inner cavity of which is provided with a heating chamber and a drying chamber, with a heat insulation plate between the heating chamber and the drying chamber. A heating assembly is provided in the inner cavity of the heating chamber. A feed inlet is provided at the top of the heating box. A U-shaped mounting frame is provided in the middle of the heat insulation plate. The inner cavity of the U-shaped mounting frame is provided with two mutually symmetrical first slide rails. A container is fixedly installed at the output end of the two first slide rails. Rectangular grooves are provided on the opposite side walls of the U-shaped mounting frame. Connectors are fixedly installed on the side walls of the container. Two connectors are movably inserted through the rectangular grooves, and the other ends of the two connectors are movably connected to the inner wall of the heating box.

[0007] The heating chamber is equipped with a drive mechanism and a transmission mechanism. The drive mechanism drives the transmission mechanism to move. By placing the prepared silicon powder, water, and ethanol solution into the inner cavity of the container, the motor is started via the PLC control panel. The motor drives the drive mechanism, which in turn moves the container into the heating chamber via a connecting piece. Heating is then achieved through the heating components. During movement, the drive mechanism moves the second slide rail via a movable rod, thus moving the transmission mechanism. With the assistance of the transmission mechanism, two baffles seal the upper feed inlet, achieving a dry environment inside the heating chamber and facilitating the manufacture of hydrophobic silicon powder.

[0008] In a preferred embodiment of the present invention, the driving mechanism includes two threaded rods, which are symmetrical to each other. Both threaded rods movably penetrate the outer wall of the heating chamber and are respectively engaged with connecting members. A motor is fixedly mounted at one end of each threaded rod, and the other ends of both threaded rods are movably connected to a heat insulation plate. This determines the installation position and components of the driving mechanism.

[0009] In a preferred embodiment of the present invention, the inner wall of the drying chamber is provided with four symmetrically arranged second slide rails. Each of the four second slide rails has a movable rod movably mounted at its output end, and the other end of each of the four movable rods is movably connected to two connecting members. This ensures that the drive mechanism can move the movable rods, and the movable rods can drive the second slide rails to move.

[0010] In a preferred embodiment of the present invention, the transmission mechanism includes four first racks, which are symmetrically arranged in pairs. Each of the four first racks is positioned above the output end of a second slide rail. A drive gear is meshed on top of each of the four first racks. A second rack is meshed on the side of each drive gear away from the first rack. A third slide rail is positioned on the side of each second rack near the inner wall of the heating chamber. This determines the installation position and components of the transmission mechanism.

[0011] In a preferred embodiment of the present invention, each of the four drive gears has a rotating rod movably mounted on one side wall near the inner wall of the heating chamber, and the other end of the rotating rod is fixedly connected to the inner wall of the heating chamber. This ensures that the drive gears can rotate without falling off.

[0012] In a preferred embodiment of the present invention, each of the four symmetrically arranged second racks is provided with a baffle. Two baffles are respectively fixedly connected to the four symmetrically arranged second racks, and two baffles are respectively slidably connected to the upper inner wall of the heating chamber. This ensures that, with the assistance of the transmission mechanism, the two baffles can block the upper feed inlet, thus achieving a dry environment inside the heating chamber, making the manufacturing of hydrophobic silica powder more convenient.

[0013] A novel method for preparing hydrophobic silica powder includes the following steps: First, the prepared silica powder, water, and ethanol solution are placed in the inner cavity of a container. The motor is started via a PLC control panel, and the motor drives the drive mechanism to run. The container is driven into the heating chamber via a connecting part, where it is heated by a heating component. During the movement of the drive mechanism, the second slide rail is moved via a movable rod, which in turn moves the transmission mechanism. With the assistance of the transmission mechanism, two baffles can block the upper feed port, achieving a dry environment inside the heating chamber, making the manufacturing of hydrophobic silica powder more convenient.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This invention involves placing a prepared silicon micropowder, water, and ethanol solution into the inner cavity of a container. The motor is then activated via a PLC control panel, driving a drive mechanism that moves the container into a heating chamber via a connecting piece. Heating is then achieved through a heating assembly. During this movement, the drive mechanism moves a second slide rail via a movable rod, which in turn moves a transmission mechanism. With the assistance of the transmission mechanism, two baffles seal the upper feed inlet, thus achieving a dry environment inside the heating chamber and facilitating the manufacture of hydrophobic silicon micropowder.

[0016] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0023] like Figures 1 to 3As shown, a novel preparation system for hydrophobic silica powder includes a heating box 1. The heating box 1 has a heating chamber 5 and a drying chamber 6 inside. A heat insulation plate 7 is placed between the heating chamber 5 and the drying chamber 6. A heating component 4 is placed inside the heating chamber 5. A feed inlet 2 is opened at the top of the heating box 1. A U-shaped mounting frame 8 is placed in the middle of the heat insulation plate 7. Two symmetrical first slide rails 9 are set inside the U-shaped mounting frame 8. A container 10 is fixedly installed at the output end of the two first slide rails 9. Rectangular grooves 11 are opened on the opposite side walls of the U-shaped mounting frame 8. Connectors 12 are fixedly installed on the side walls of the container 10. The two connectors 12 are movably inserted through the rectangular grooves 11. The other ends of the two connectors 12 are movably connected to the inner wall of the heating box 1. A driving mechanism and a transmission mechanism are set inside the heating box 1. The driving mechanism is used to drive the transmission mechanism to move. By placing the prepared silicon micro powder, water, and ethanol solution into the inner cavity of the container 10, the motor 3 is started via the PLC control panel. The motor 3 drives the drive mechanism to run, which can drive the container 10 into the heating chamber 5 through the connector 12. Heating is achieved through the heating component 4. During the movement, the drive mechanism can drive the second slide rail 15 to move through the movable rod 14, thus driving the transmission mechanism to move. With the assistance of the transmission mechanism, the two baffles 20 can block the upper feed port 2, thus achieving dryness inside the heating box 1, making it more convenient to manufacture hydrophobic silicon micro powder.

[0024] The drive mechanism includes two threaded rods 13, which are symmetrical to each other. Both threaded rods 13 movably penetrate the outer wall of the heating box 1 and are respectively engaged with the connecting piece 12. A motor 3 is fixedly installed at one end of each threaded rod 13, and the other end of each threaded rod 13 is movably connected to the heat insulation plate 7. In this configuration, the installation position and components of the drive mechanism are determined.

[0025] The inner wall of the drying chamber 6 is provided with four symmetrically arranged second slide rails 15. Each of the four second slide rails 15 has a movable rod 14 movably mounted at its output end. The other ends of the four movable rods 14 are respectively movably connected to two connecting pieces 12. In this configuration, the installation position of the movable rods 14 is determined to ensure that the drive mechanism can move the movable rods 14, and the movable rods 14 can drive the second slide rails 15 to move.

[0026] The transmission mechanism includes four first racks 16, which are symmetrically arranged in pairs. Each of the four first racks 16 is positioned above the output end of a second slide rail 15. A drive gear 17 is meshed on each of the four first racks 16. A second rack 18 is meshed on the side of each drive gear 17 furthest from the first racks 16. A third slide rail 19 is positioned on the side of each second rack 18 closest to the inner wall of the heating chamber 1. This configuration defines the installation position and components of the transmission mechanism.

[0027] Each of the four drive gears 17 has a rotating rod movably mounted on one side wall near the inner wall of the heating chamber 1, and the other end of the rotating rod is fixedly connected to the inner wall of the heating chamber 1. This design ensures that the drive gears 17 can rotate without falling off.

[0028] Each of the four symmetrically arranged second racks 18 is equipped with a baffle 20. Two baffles 20 are fixedly connected to each of the four symmetrically arranged second racks 18, and two baffles 20 are slidably connected to the upper inner wall of the heating chamber 1. In this configuration, with the assistance of the transmission mechanism, the two baffles 20 can block the upper feed port 2, thus enabling the interior of the heating chamber 1 to become dry, making the manufacture of hydrophobic silica powder more convenient.

[0029] The implementation principle of the novel preparation system for hydrophobic silicon micropowder in this embodiment is as follows: First, the prepared silicon micropowder, water, and ethanol solution are placed in the inner cavity of the container 10. At this time, the motor 3 is started through the PLC control panel. The motor 3 drives the drive mechanism to run, which can drive the container 10 into the heating chamber 5 through the connector 12. Heating can be carried out through the heating component 4. During the movement, the drive mechanism can drive the second slide rail 15 to move through the movable rod 14, thus driving the transmission mechanism to move. With the assistance of the transmission mechanism, the two baffles 20 can block the upper feed port 2, thus achieving dryness inside the heating box 1, making it more convenient to manufacture hydrophobic silicon micropowder.
