Description

Technical Field

[0001] This utility model relates to the field of grinding technology, and in particular to a pre-grinding device for coarse pigment Violet 23. Background Technology

[0002] Pigment Violet 23 refers to a substance that can color objects. During the production process of Pigment Violet 23, the coarse Pigment Violet 23 needs to be ground into fine particles to form abrasive particles.

[0003] A search revealed that Chinese Patent Publication No. CN219898452U discloses a mineral pigment grinding machine. This technical solution uses large-diameter and small-diameter grinding blades for pre-crushing when grinding pigments. However, after crushing, it is difficult to ensure that all pigments entering the grinding chamber are small particles. The lack of a mechanism for circulating and crushing pigments makes it difficult for the device to grind pigments. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a pre-grinding device for crude pigment Violet 23.

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

[0006] A pre-grinding device for crude pigment Violet 23, comprising:

[0007] Fixed base;

[0008] Two side plates are symmetrically fixedly installed on the top of the fixing base;

[0009] A conical grinding table, a grinding hood, and a pulverizing tank are arranged sequentially above a fixed base from bottom to top. The conical grinding table is placed inside the grinding hood, and the pulverizing tank is fixedly connected to the top of the grinding hood. A conical toothed ring surrounds the outside of the pulverizing tank. Two support frames are fixedly connected between the conical toothed ring, the outer ring of the bearing, the outer side of the conical grinding table, and the two side plates. Multiple filter holes are provided at the connection between the pulverizing tank and the grinding hood.

[0010] The collection basin is movably mounted on top of the fixed base and placed below the conical grinding table;

[0011] The circulating crushing component is used to move and crush the crude pigment Violet 23 in the crushing tank from bottom to top.

[0012] Preferably, the circulating crushing assembly includes a dual-shaft motor fixedly installed on the front side of the crushing tank. One drive end of the dual-shaft motor is fixedly installed with a bevel gear, which meshes with a bevel gear ring. The other drive end of the dual-shaft motor movably passes through the front side of the crushing tank and is fixedly installed with a crushing shaft. Multiple crushing blades are fixedly installed on the surface of the crushing shaft, and two scrapers are fixedly connected to the surface of the crushing shaft by two fixing rods, and the scrapers movably fit against the inner surface of the crushing tank.

[0013] Preferably, the top of the fixing seat is provided with a positioning groove, and the positioning groove is slidably connected to the collection basin.

[0014] Preferably, the inner diameter of the collection basin is larger than the outer diameter of the grinding cover.

[0015] Preferably, the sidewalls of the conical grinding table and the inner sidewalls of the grinding cover are coated with abrasive particles.

[0016] Compared with existing technologies, the advantages of the pre-grinding device for coarse pigment Violet 23 provided by this utility model are as follows:

[0017] This invention uses a dual-axis motor to control the crushing shaft, causing each crushing blade and scraper to move in a circular motion. The crushing blades can crush pigment purple 23, and the crushed small particles can enter the grinding hood through the filter holes. Larger pigment purple 23 particles are carried up from bottom to top by the scraper and then fall freely from a height to contact the crushing blades again. This achieves repeated crushing of pigment purple 23, thereby achieving sufficient pre-crushing of the crude pigment purple 23 and reducing the difficulty of grinding pigment purple 23.

[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 4 A pre-grinding mill for crude pigment Violet 23, comprising:

[0025] Fixed base 1; two side plates 2, symmetrically fixedly installed on the top of fixed base 1.

[0026] The conical grinding table 3, the grinding hood 4, and the pulverizing tank 5 are arranged sequentially above the fixed base 1 from bottom to top. The side wall of the conical grinding table 3 and the inner side wall of the grinding hood 4 are coated with abrasive particles. When the grinding hood 4 and the conical grinding table 3 grind the coarse pigment Violet 23, the friction between the abrasive particles and the pigment Violet 23 particles can effectively grind the pigment Violet 23 particles into finer particles, thereby improving the color intensity and dispersibility of the pigment.

[0027] The conical grinding table 3 is placed inside the grinding cover 4. The grinding tank 5 is fixedly connected to the top of the grinding cover 4, and the outer side of the grinding tank 5 is surrounded by a conical tooth ring 9. Two support frames 10 are fixedly connected between the conical tooth ring 9, the outer ring of the bearing 7, the outer side of the conical grinding table 3, and the two side plates 2. Multiple filter holes 8 are opened at the connection between the grinding tank 5 and the grinding cover 4. When the coarse pigment purple 23 is ground, the smaller particles after grinding will enter the grinding cover 4 through the filter holes 8 for grinding, while the larger particles of pigment purple 23 will be retained in the grinding tank 5 and will not enter the grinding cover 4, thereby reducing the difficulty of grinding pigment purple 23.

[0028] The collection basin 6 is movably installed on the top of the fixed base 1 and placed below the conical grinding table 3. The top of the fixed base 1 is provided with a positioning groove 15, and the positioning groove 15 is slidably connected to the collection basin 6 so that when the collection basin 6 is placed, it can be quickly aligned with the bottom of the conical grinding table 3. The inner diameter of the collection basin 6 is larger than the outer diameter of the grinding cover 4, ensuring that the powder being ground between the grinding cover 4 and the conical grinding table 3 can fall smoothly into the collection basin 6.

[0029] The circulating crushing assembly is used to move and crush the crude pigment purple 23 in the crushing tank 5 from bottom to top. The circulating crushing assembly includes a dual-shaft motor 11 fixedly installed on the front side of the crushing tank 5. A bevel gear 12 is fixedly installed on one drive end of the dual-shaft motor 11 and meshes with a bevel gear ring 9. The other drive end of the dual-shaft motor 11 moves through the front side of the crushing tank 5 and is fixedly installed with a crushing shaft. Multiple crushing blades 13 are fixedly installed on the surface of the crushing shaft, and two scrapers 14 are fixedly connected to the surface of the crushing shaft by two fixing rods 16, and the scrapers 14 move and fit against the inner surface of the crushing tank 5.

[0030] The working principle of this utility model is as follows:

[0031] In use, first start the dual-shaft motor 11, then pour the coarse pigment purple 23 to be ground into the grinding tank 5. At this time, the dual-shaft motor 11 controls the grinding shaft to make each grinding blade 13 and scraper 14 move in a circular motion. The grinding blade 13 can grind the pigment purple 23, and the small particles after grinding can enter the grinding hood 4 through the filter hole 8. The large particles of pigment purple 23 will be carried up from bottom to top by the scraping of the scraper 14, and then fall freely from a high place to contact the grinding blade 13 again, thus realizing the repeated grinding of pigment purple 23.

[0032] Pigment violet 23 enters the grinding chamber 4. When the dual-shaft motor 11 controls the rotation of the crushing shaft, it also drives the bevel gear 12 to rotate synchronously. This causes the bevel gear 12 to circulate and roll on the bevel gear ring 9, which in turn drives the grinding chamber 4 to rotate on the conical grinding table 3. The grinding of pigment violet 23 can be achieved by utilizing the gap between the two.

[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.
