Description

Technical Field

[0001] This utility model relates to the field of grinding and dispersing machine technology, and in particular to a grinding and dispersing machine for organosilicon surface treatment agents. Background Technology

[0002] Organosilicon possesses excellent properties, thus its applications are very wide-ranging. It can be used as a special material in aerospace, cutting-edge technology, and military technology sectors. The surface treatment of organosilicon is typically performed in a disperser during the polishing process.

[0003] Currently, existing dispersers typically use rotating grinding balls within a grinding tank to frictionally treat the passing organosilicon before directly discharging it. However, this friction-discharge method fails to allow for continuous grinding, resulting in the presence of large organosilicon particles and insufficient grinding. Furthermore, the fixed position of the feeding hopper causes organosilicon to accumulate in a specific location within the grinding tank, preventing even dispersion and resulting in poor grinding efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the background art by proposing a grinding and dispersing machine for organosilicon surface treatment agents.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An organosilicon surface treatment agent grinding and dispersing machine, comprising:

[0007] A hemispherical grinding shell, with a funnel-shaped feed hopper at the top of the hemispherical grinding shell, and a fixing frame fixedly installed on the outer wall of the hemispherical grinding shell;

[0008] A gathering tube is fixedly installed at the bottom of the hemispherical grinding shell, and a screening cylinder is provided inside the gathering tube. The screening cylinder is fixedly connected to the bottom of the hemispherical grinding shell. A right-angle frame is fixedly installed at the top of the trumpet-shaped feed hopper. A drive motor for driving the rotating shaft to rotate is fixedly installed at the top of the right-angle frame. A rotating shaft is rotatably installed at the inner top of the right-angle frame, and the lower end of the rotating shaft is rotatably installed at the inner bottom of the screening cylinder. A transfer tube surrounds the outer side of the rotating shaft. Grinding balls are fixedly fitted on the surface of the transfer tube, and a spiral blade is provided inside the transfer tube. The spiral blade is fixedly fitted on the surface of the rotating shaft.

[0009] The feeding hopper is fixedly connected to the surface of the transfer pipe via a return pipe, and the lower port of the feeding hopper is placed inside the funnel-shaped feeding hopper;

[0010] A differential assembly is used to drive the transfer tube to rotate rapidly and is disposed between the transfer tube and the rotating shaft.

[0011] Preferably, the differential assembly includes a large gear and a small gear fixedly mounted on the surface of the rotating shaft and the top of the right-angle bracket, respectively, and the large gear and the small gear mesh with each other. The surfaces of the transfer tube and the small gear are both fixedly mounted with transmission gears, and the two transmission gears mesh with each other.

[0012] Preferably, the diameter of the grinding ball is smaller than the inner diameter of the hemispherical grinding shell, and the grinding ball and the hemispherical grinding shell are concentrically arranged.

[0013] Preferably, the edge of the spiral blade slides against the inner surface of the transfer tube.

[0014] Preferably, a support plate is movably fitted onto the surface of the transfer tube, and the end of the support plate is fixedly installed inside a right-angle frame and rotatably mounted on the bottom of both transmission gears.

[0015] Compared with existing technologies, the advantages of the organosilicon surface treatment agent grinding and dispersing machine provided by this utility model are as follows:

[0016] 1. The rotating shaft is controlled by the drive motor. Under the differential transmission of the differential component, the transfer tube drives the grinding ball to rotate quickly. At the same time, the feeding hopper will also move in a circular motion with the rotation of the transfer tube, so that the organosilicon is evenly dispersed and put into the hemispherical grinding shell, which can fully frictionally grind the organosilicon.

[0017] 2. The ground organosilicon particles enter the screening cylinder. Small particles pass through the screening cylinder and are discharged from the lower end of the gathering pipe, while large particles are moved upward from the screening cylinder by the rotating spiral blades controlled by the rotating shaft and re-enter the feeding hopper through the return pipe, and are then fed back into the hemispherical grinding shell for cyclic grinding.

[0018] In summary, this invention, through the rotation of the grinding balls by the drive motor and the circumferential motion of the feeding hopper, can evenly disperse organosilicon and feed it into the hemispherical grinding shell for thorough frictional grinding. At the same time, under the conveying action of the spiral blades, the large particles of organosilicon after grinding can be circulated back into the feeding hopper for further grinding, thereby improving the grinding effect and processing efficiency of organosilicon.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 3 An organosilicon surface treatment agent grinding and dispersing machine, comprising:

[0025] The hemispherical grinding shell 1 has a funnel-shaped feed hopper 2 at the top and a fixing frame 3 is fixedly installed on the outer wall of the hemispherical grinding shell 1. The other end of the fixing frame 3 can be installed in a specified environment to fix the hemispherical grinding shell 1.

[0026] A gathering tube 4 is fixedly installed at the bottom of the hemispherical grinding shell 1, and a screening cylinder 5 is provided inside the gathering tube 4. The screening cylinder 5 is fixedly connected to the bottom of the hemispherical grinding shell 1. A right-angle frame 11 is fixedly installed at the top of the trumpet-shaped feed hopper 2. A drive motor 12 for driving the rotating shaft 13 to rotate is fixedly installed at the top of the right-angle frame 11. The rotating shaft 13 is rotatably installed at the top inner part of the right-angle frame 11, and the lower end of the rotating shaft 13 is rotatably installed at the bottom inner part of the screening cylinder 5. A transfer tube 6 surrounds the outside of the rotating shaft 13. Grinding balls 8 are fixedly fitted on the surface of the transfer tube 6. The diameter of the grinding balls 8 is smaller than the inner diameter of the hemispherical grinding shell 1, and the grinding balls 8 and the hemispherical grinding shell 1 are concentrically arranged. When the organosilicon enters the gap between the hemispherical grinding shell 1 and the grinding balls 8, it can be ground by friction between the two.

[0027] Furthermore, the transfer pipe 6 is equipped with a spiral blade 14, which is fixedly mounted on the surface of the rotating shaft 13. The feeding hopper 10 is fixedly connected to the surface of the transfer pipe 6 through the return pipe 9. The lower port of the feeding hopper 10 is also equipped with a solenoid valve, and the lower port of the feeding hopper 10 is placed inside the funnel-shaped feed hopper 2. When the spiral blade 14 rotates, it can intercept larger organosilicon particles in the screening cylinder 5 and re-convey them upward until they enter the feeding hopper 10 through the return pipe 9. Then, they re-enter the hemispherical grinding shell 1 for grinding again, so as to achieve the effect of fully grinding the organosilicon in a cycle.

[0028] A differential assembly is used to drive the transfer tube 6 to rotate rapidly and is located between the transfer tube 6 and the rotating shaft 13. The differential assembly includes a large gear 15 and a small gear 16, which are respectively fixedly mounted on the surface of the rotating shaft 13 and the top of the right-angle bracket 11, and the large gear 15 and the small gear 16 mesh with each other. Transmission gears 17 are fixedly mounted on the surfaces of the transfer tube 6 and the small gears 16, and the two transmission gears 17 mesh with each other. A support plate 7 is movably mounted on the surface of the transfer tube 6, and the end of the support plate 7 is fixedly mounted in the right-angle bracket 11 and rotatably mounted on the bottom of the two transmission gears 17, which plays a supporting role for the transfer tube 6.

[0029] The working principle of this utility model is as follows:

[0030] When in use, pour the organosilicon to be ground into the feeding hopper 10, then connect the external power supply of the device and start the drive motor 12. At this time, the solenoid valve opens and the organosilicon falls into the hemispherical grinding shell 1.

[0031] Next, the drive motor 12 controls the rotating shaft 13 to rotate. At this time, under the differential transmission of the large gear 15, the small gear 16 and the two transmission gears 17, the transfer tube 6 drives the grinding ball 8 to rotate quickly, which can perform friction grinding on the organosilicon. At the same time, the feeding hopper 10 will also move in a circular motion with the rotation of the transfer tube 6, and evenly disperse the organosilicon into the hemispherical grinding shell 1.

[0032] The ground organosilicon particles enter the screening cylinder 5. Small particles pass through the screening cylinder 5 and are discharged from the lower end of the gathering pipe 4 under the restriction of the gathering pipe 4. Large particles are moved upward from the screening cylinder 5 and re-enter the feeding hopper 10 through the return pipe 9 under the rotation of the spiral blades 14 controlled by the rotating shaft 13. They are then fed back into the hemispherical grinding shell 1 for cyclic grinding.

[0033] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
