Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a material stirring device for fine chemicals. Background Art

[0002] Chemical products can be divided into two categories: basic chemical products and fine chemical products. Basic chemical products are also called general chemical products or bulk chemical products. Basic chemical products refer to the basic chemical raw materials and materials produced in large quantities. They are generally the most basic material products made from basic raw materials such as cheap and easily available natural resources through one or several chemical processes; fine chemical products have special functions, high R&D, production and application technology intensity, and formulation technology often affects product performance. They have high added value and are small batches and multiple varieties of chemical products. They are called fine chemical products or fine chemicals.

[0003] The production of fine chemical products often requires the stirring of materials. In existing stirring devices, due to the certain viscosity of the materials themselves, part of the materials will adhere to the inner wall of the stirring barrel during the stirring process. People usually set a scraper in the stirring barrel that fits tightly with the inner wall of the stirring barrel, and scrape off the materials adhering to the inner wall of the stirring barrel through the mutual movement between the scraper and the stirring barrel, so that the materials can be fully stirred and mixed. However, because the materials accumulate at the bottom of the stirring barrel under the action of their own gravity, the scraper will wear faster on the side facing the rotation direction when scraping off the materials adhering to the bottom surface of the inner part of the stirring barrel.

[0039] See also Figure 1-6 The utility model provides a technical solution: a material stirring device for fine chemicals, comprising a stirring barrel 1 and a stirring part arranged in the stirring barrel 1, wherein the stirring part comprises a rotating shaft 21 rotatably connected to the stirring barrel 1 and a stirring frame 211 connected to the middle of the rotating shaft 21, and a scraper 22 is arranged in the stirring barrel 1, wherein one end of the scraper 22 is connected to the rotating shaft 21, and the other end is close to the bottom surface inside the stirring barrel 1 and extends toward the side wall of the stirring barrel 1;

[0040] The side of the scraper 22 facing the rotation direction is connected to a guide plate 31, and the side of the guide plate 31 facing the rotation direction is inclined toward the bottom surface of the mixing barrel 1;

[0041] A height adjustment component is provided between the guide plate 31 and the scraper 22 , and the height adjustment component is used to control the height position of the guide plate 31 on the scraper 22 .

[0042] A guide plate 31 is provided on the side of the scraper 22 facing the rotation direction, and the side of the guide plate 31 facing the rotation direction is inclined toward the bottom surface of the mixing barrel 1, and the scraper 22 and the guide plate 31 on the scraper 22 are driven to rotate together through the rotating shaft 21, so that the guide plate 31 pushes and lifts most of the materials on the rotation path during the rotation process, so that most of the materials pass over the guide plate 31 and fall on the scraper 22, thereby avoiding the friction with the side of the scraper 22 facing the rotation direction, so as to reduce the wear of the side of the scraper 22 facing the rotation direction; at the same time, a stirring frame 211 is provided above the scraper 22 to stir the materials; the height of the guide plate 31 on the scraper 22 is adjusted by the height adjustment component, thereby changing the size of the gap between the bottom edge of the lower side of the guide plate 31 and the bottom surface of the mixing barrel 1, so that the materials adhered to the bottom surface of the mixing barrel 1 pass through the gap, and then are pushed to move by the side of the scraper 22 facing the rotation direction, so as to achieve the purpose of scraping off the materials adhered to the bottom surface of the mixing barrel 1.

[0043] In this embodiment, the side surface of the scraper 22 facing the rotation direction is an inclined surface with the top edge inclined toward the middle of the scraper 22 .

[0044] The side of the scraper 22 facing the rotation direction is set as an inclined surface, and the top edge is inclined toward the middle of the scraper 22, and the bottom surface of the scraper 22 is abutted against the bottom surface of the inside of the mixing barrel 1, so as to facilitate scraping off the material adhering to the bottom surface of the inside of the mixing barrel 1; by rotating the scraper 22, the side of the scraper 22 facing the rotation direction pushes the material to be lifted, and the material moves along the inclined surface to the top of the scraper 22, so that the material can be stirred and mixed with other materials.

[0045] In this embodiment, a sliding groove 221 extending from the top edge to the bottom edge is provided on the side of the scraper 22 facing the rotation direction;

[0046] The height adjustment assembly includes a slider 32 that is slidably fitted in the slide slot 221, and the upper end of the slider 32 extends upward out of the slide slot 221 and is fixedly connected to the bottom surface of the guide plate 31;

[0047] A spring 33 is disposed between the slider 32 and the inner walls of both ends of the slide groove 221 . When the spring 33 is in a naturally extended state, the lower side of the guide plate 31 abuts against the bottom surface of the mixing barrel 1 .

[0048] When in use, the rotating shaft 21 drives the scraper 22 and the guide plate 31 on the scraper 22 to rotate together. When the guide plate 31 rotates, it pushes and squeezes the material on the rotating track, and then the material has a reaction force on the guide plate 31, prompting the guide plate 31 to push the slider 32 to move toward the upper end of the slide groove 221, so as to increase the gap size between the bottom edge of the downward side of the guide plate 31 and the inner bottom surface of the mixing barrel 1. At the same time, the springs 33 at both ends of the slide groove 221 are deformed to store energy; different amounts of materials are added to the mixing barrel 1 and stirred respectively. Since the reaction forces of different amounts of materials on the guide plate 31 are different, the deformation amount of the spring 33 is different each time the stirring is performed, and then the gap size between the bottom edge of the downward side of the guide plate 31 and the inner bottom surface of the mixing barrel 1 is different, so that the height adjustment component can automatically adjust the gap size between the bottom edge of the downward side of the guide plate 31 and the inner bottom surface of the mixing barrel 1 according to the amount of materials, thereby improving the passability of the materials between the guide plate 31 and the scraper 22.

[0049] In this embodiment, a cover plate 34 is fixedly connected to the middle of the sliding block 32 . The cover plate 34 covers the sliding groove 221 and is sealed with the surface of the scraper 22 .

[0050] A cover plate 34 is provided in the middle of the slide block 32 , and the slide groove 221 is covered by the cover plate 34 , so as to prevent materials from entering the slide groove 221 and affecting the normal operation of the spring 33 .

[0051] In this embodiment, an end of the scraper 22 away from the rotating shaft 21 is fixedly connected to an arc-shaped plate 23 extending upward, and the outer circumferential surface of the arc-shaped plate 23 is in contact with the inner side of the mixing barrel 1 .

[0052] The mixing barrel 1 is in the shape of a hollow cylinder. An arc-shaped plate 23 is arranged at one end of the scraper 22 away from the rotating shaft 21. The scraper 22 drives the arc-shaped plate 23 and the mixing barrel 1 to move relative to each other, so as to scrape off the materials adhering to the inner side surface of the mixing barrel 1 and promote the stirring and mixing of the materials. A top plate 25 is arranged above the scraper 22, and the two ends of the top plate 25 are respectively fixedly connected to the upper end of the arc-shaped plate 23 and the upper end of the rotating shaft 21, so as to improve the stability of the arc-shaped plate 23.

[0053] In this embodiment, the stirring frame 211 includes a stirring shaft 2111 parallel to the scraper 22 and a stirring rod 2112 fixedly connected to the outer cylindrical surface of the stirring shaft 2111. One end of the stirring shaft 2111 is rotatably matched with the arc plate 23, and the other end is rotatably matched with the rotating shaft 21.

[0054] The scraper 22 and the stirring frame 211 above the scraper 22 are driven by the rotating shaft 21 to rotate around the rotating shaft 21 to achieve the purpose of horizontal stirring of materials; the stirring shaft 2111 is set parallel to the scraper 22, so that the motion trajectory plane of the stirring rod 2112 on the stirring shaft 2111 is perpendicular to the motion trajectory plane of the scraper 22 to achieve the purpose of vertical stirring of materials.

[0055] In this embodiment, the rotating shaft 21 is a hollow structure with an opening at the upper end. A bracket 11 is provided at the top of the side wall of the mixing barrel 1. One end of the bracket 11 is fixedly connected to the side wall of the mixing barrel 1, and the other end extends downward into the interior of the rotating shaft 21 at the opening of the rotating shaft 21 and rotates with the rotating shaft 21. One end of the bracket 11 inside the rotating shaft 21 is fixedly connected to a second bevel gear 24;

[0056] One end of the stirring shaft 2111 away from the arc plate 23 penetrates through the side wall of the rotating shaft 21 and extends into the rotating shaft 21 , and is fixedly connected to a first bevel gear 2113 meshing with the second bevel gear 24 .

[0057] The bracket 11 is in the shape of the letter "L", one section of which is arranged horizontally and the end is fixedly connected to the inner wall of the mixing barrel 1, and the other section is arranged vertically and the end is fixedly connected to the upper end of the second bevel gear 24; by rotating the rotating shaft 21, the rotating shaft 21 drives the stirring shaft 2111 to revolve around the vertical section of the bracket 11 as the center, and a first bevel gear 2113 meshing with the second bevel gear 24 is arranged on the stirring shaft 2111, so that when the stirring shaft 2111 drives the first bevel gear 2113 to revolve around the vertical section of the bracket 11, the first bevel gear 2113 rotates under the action of the second bevel gear 24, and then drives the stirring rod 2112 to rotate through the stirring shaft 2111, so that the horizontal stirring and vertical stirring of the material are carried out simultaneously, thereby improving the working efficiency of material stirring.

[0058] In this embodiment, the lower end of the rotating shaft 21 passes through the bottom wall of the mixing barrel 1, extends out of the mixing barrel 1, and rotates with the bottom wall of the mixing barrel 1; the motor 4 is fixedly connected to the bottom surface outside the mixing barrel 1, and the output end of the motor 4 is fixedly connected to the lower end of the rotating shaft 21.

[0059] The stability of the rotating shaft 21 and the scraper 22 on the rotating shaft 21 is improved by rotating the upper and lower ends of the rotating shaft 21 with the vertical section of the bracket 11 and the bottom wall of the mixing barrel 1 respectively; the motor 4 is used to increase the power for the rotation of the rotating shaft 21, and its specific model is Demark 180M-35015E-E.
