Description

Technical Field

[0001] The utility model relates to the technical field of planetary dispersers, in particular to a planetary disperser. Background Art

[0002] Planetary disperser is used for stirring, dispersing and crushing high viscosity products. Its structure includes a closed container and a planetary frame. The planetary frame can drive the dispersion disk to rotate through the transmission shaft. The planetary frame can also rotate on itself, thereby driving the dispersion disk to revolve, and then the dispersion disk can achieve efficient dispersion of the material.

[0003] In the prior art, materials are dispersed in a closed container of a planetary disperser. High-viscosity materials will adhere to the inner wall of the container and gradually climb upward, even to the container wall corresponding to the position of the planetary frame. The materials adhered here are difficult to clean, resulting in material waste. At the same time, high-viscosity components in the material gradually adhere to the inner wall of the container, making the material thinner and affecting the quality of the material. The thinned material will adhere to the surface of the observation mirror arranged on the container, blocking the line of sight and hindering observation. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a planetary disperser, which effectively cleans the material attached to the wall of the container by setting a vacuum hood, a limit ring and a scraper, avoids material waste and ensures material quality; at the same time, it can effectively prevent material from adhering to the surface of the observation mirror, making it convenient for personnel to observe the working progress of the planetary disperser.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A planetary disperser comprises a frame, a planetary frame is mounted on the frame, a connecting shaft is fixed to the bottom of the planetary frame, an output end transmission shaft of the planetary frame, at least one dispersion disc is mounted on the outer circumference of the transmission shaft, and a wall scraper is mounted on the outer circumference of the connecting shaft;

[0007] It also includes a container, a vacuum cover is installed on the top of the container, the top of the vacuum cover is fixed to the frame, and the vacuum cover surrounds the planetary frame;

[0008] The inner diameter of the vacuum cover is smaller than the inner diameter of the container, so that a limiting ring is formed between the vacuum cover and the container, and the limiting ring prevents the material in the container from entering the vacuum cover;

[0009] The planet carrier drives the transmission shaft to rotate, thereby driving the dispersion disk to rotate through the transmission shaft, thereby shearing and dispersing the material in the container;

[0010] The planet carrier rotates, thereby correspondingly driving the scraper and the dispersion disk to revolve through the connecting shaft and the transmission shaft;

[0011] When the wall scraper revolves, the materials attached to the inner wall surface of the container and the inner bottom wall surface of the limiting circular ring are scraped off.

[0012] As a further improvement of the above technical solution:

[0013] The vacuum cover and the container are both cylindrical and their internal spaces are communicated.

[0014] The vacuum hood is arranged concentrically with the container.

[0015] The bottom of the container is equipped with guide wheels.

[0016] The rotation direction of the dispersion disk is opposite to the revolution direction of the dispersion disk.

[0017] The structure of the wall scraper is as follows: it includes a sleeve mounted in cooperation with the connecting shaft, a first mounting rod and a second mounting rod are respectively arranged on the outer wall surface of the sleeve, a top scraper is mounted in cooperation with the end of the first mounting rod, the second mounting rod is L-shaped, and a side scraper is mounted in cooperation with the side wall surface of the vertical section of the second mounting rod;

[0018] The top working end surface of the top scraper scrapes off the material attached to the inner bottom wall surface of the limiting circular ring, and the side working end surface of the top scraper scrapes off the material attached to the upper part of the inner wall surface of the container;

[0019] The side working end surface of the side scraper scrapes off the material attached to the lower middle part of the inner wall surface of the container.

[0020] The long side direction of the top scraper is arranged parallel to the radial direction of the sleeve, and at the same time, the short side direction of the top scraper is arranged with a certain angle deflected relative to the axis of the sleeve.

[0021] A spoiler is arranged on the side wall surface of the vertical section of the second mounting rod.

[0022] The bottom end surface of the side scraper is lower than the bottom end surface of the second mounting rod.

[0023] The frame is equipped with a lifting seat, which is used to drive the container to perform a linear motion of ascending or descending in a vertical direction.

[0024] The beneficial effects of the utility model are as follows:

[0025] The utility model has a compact and reasonable structure and is easy to operate. By arranging the container, the vacuum cover and the limiting ring, it can hinder the climbing of materials attached to the side wall of the container, thereby effectively preventing the materials in the container from climbing to the position of the planetary frame, facilitating subsequent cleaning, avoiding material waste, preventing the materials from becoming thin, and ensuring the quality of the materials.

[0026] The utility model also has the following advantages:

[0027] (1) In the utility model, by providing a wall scraper, the material adhering to the side wall of the container and the inner bottom wall of the limiting ring can be scraped off, thereby preventing the material from becoming thinner, ensuring the material quality, and reducing material waste.

[0028] (2) In the utility model, by arranging the top scraper at an angle, the material can be scraped off more effectively. At the same time, the material can be prevented from continuing to climb, ensuring that all the scraped material can fall into the container.

[0029] (3) In the present invention, by making the bottom end surface of the side scraper lower than the bottom end surface of the second mounting rod, the contact area between the side scraper and the inner wall of the container can be ensured, thereby scraping off the material in the middle and lower part of the inner wall of the container as much as possible.

[0030] (4) In the utility model, by providing a spoiler, the material inside the container can be stirred to enhance the flow field of the material.

[0031] (5) The rotation direction of the dispersion disk in the utility model is opposite to the revolution direction, which can effectively stir, shear and disperse the materials inside the container, thereby improving the quality of subsequent products. BRIEF DESCRIPTION OF THE DRAWINGS
