Description

Technical Field

[0001] This utility model relates to the field of air classifier technology, specifically to a baffle cone device for an air classifier. Background Technology

[0002] Currently, air classifiers use two main types of baffle cone devices: one is the wire rope-suspended impact cone device, which mainly consists of guide wheels, wire ropes, the impact cone body, a cast cone cap, and a liner. The other is the bolt-suspended impact cone device, which mainly consists of rectangular hollow steel sections, suspension bolts, the impact cone body, a cast cone cap, and a liner. The impact cone body of the baffle cone device is connected to the inner cone of the air classifier. Coarse powder falls from the classification zone into the inner cone, where it is dispersed through the annular gap between the inner cone and the impact cone. The rising mixed gas further classifies this portion of the material, forming an internal circulation classification system within the air classifier to improve its classification efficiency.

[0003] The shortcomings of these structures are their complexity and imprecise installation and adjustment. When sorting different materials or different finenesses, the annular gap between the impact cone and the inner cone is prone to being too narrow or too wide, which affects the improvement of classification efficiency.

[0004] The high-efficiency baffle cone device for air classifiers disclosed in announcement number CN201534143U can form an internal circulation separation of coarse powder falling from the air classifier zone, thereby improving the separation efficiency. Moreover, it is simple to manufacture and easy to install.

[0005] However, during long-term production, the baffle cone of the device wears out severely and cannot be repaired by adding wear-resistant plates. It requires the extensive dismantling of equipment parts, resulting in high maintenance costs. Furthermore, it cannot break up agglomerated or clustered materials, leading to uneven material dispersion and reduced powder selection accuracy and efficiency.

[0006] Therefore, we urgently need to provide a baffle cone device for a classifier. Utility Model Content

[0007] The purpose of this utility model is to provide a baffle cone device for a classifier, in order to solve the problems mentioned in the background art, such as severe wear of the baffle cone during long-term production, which cannot be repaired by adding wear-resistant plates, requires large-area disassembly of equipment parts, resulting in high maintenance costs, and is unable to disperse agglomerated or clustered materials, leading to uneven material dispersion and reduced classifier accuracy and efficiency.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a baffle cone device for an air classifier, comprising a baffle cone body, a silicon steel mesh fixedly installed on the outer side of the baffle cone body, a ceramic wear-resistant coating fixedly installed on the outer side of the silicon steel mesh, and a dispersing device provided on the outer side of the ceramic wear-resistant coating. The dispersing device includes an installation block, a dispersing plate, an installation frame, a spring, a baffle plate, a clamping rod, a pull rod, and a connecting plate. The installation block is fixedly installed on the outer side of the ceramic wear-resistant coating, the dispersing plate is installed inside the installation block, the installation frame is fixedly installed on the outer side of the installation block, one end of the spring is fixedly installed on the left and right sides of the inner wall of the installation frame, the baffle plate is fixedly installed on the other end of the spring, the clamping rod is fixedly installed on the side of the baffle plate away from the spring, one end of the pull rod is fixedly installed on the side of the baffle plate away from the clamping rod, and the connecting plate is fixedly installed on the other end of the pull rod.

[0009] Preferably, the outer surface of the baffle cone is the windward side, and the distance between the ceramic wear-resistant coating and the windward side is one centimeter.

[0010] Preferably, the ceramic wear-resistant coating is a ceramic wear-resistant paint, and the thickness of the ceramic wear-resistant paint is fifty millimeters. By laying the ceramic wear-resistant paint, the wear resistance of the baffle cone body is improved, and the severe wear of the baffle cone body is avoided, which would cause the wear-resistant layer of the outer shell to be worn through.

[0011] Preferably, the dispersing device is distributed at equal angles on the outer surface of the ceramic wear-resistant coating. When the baffle cone body rotates, the dispersing plate disperses the agglomerated or clustered materials, making the materials more uniformly dispersed, thereby improving the accuracy and efficiency of powder selection.

[0012] Preferably, the mounting block has an I-shaped groove inside, and the disintegration plate has a groove in the middle of the side near the mounting block. The disintegration plate is inserted into the mounting block, which facilitates the installation of the disintegration plate on the mounting block.

[0013] Preferably, the disintegration plate has a locking hole inside, and the diameter of the locking hole is equal to the diameter of the locking rod. The locking rod engages with the locking hole in the disintegration plate, thereby fixing the disintegration plate to the mounting block.

[0014] Preferably, the end of the lever away from the baffle is hemispherical. The hemispherical shape makes it easier for the lever to engage with the locking hole in the disassembly plate, thereby improving the installation efficiency of the disassembly plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The baffle cone device of this air classifier improves the wear resistance of the baffle cone body by setting silicon steel mesh and ceramic wear-resistant coating, reduces the wear of the baffle cone during long-term production, and increases the service life of the baffle cone.

[0017] 2. The baffle cone device of this air classifier, by setting up a dispersing device, disperses the agglomerated or clustered materials through the dispersing plate, making the materials more uniformly dispersed, thereby improving the accuracy and efficiency of air classification.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Due to the limitations of current technology, the baffle cones suffer severe wear during long-term production, making repair impossible by simply adding wear-resistant plates. This necessitates extensive disassembly of equipment components, resulting in high repair costs. Furthermore, the technology fails to break up agglomerated or clustered materials, leading to uneven material dispersion and reduced powder selection accuracy and efficiency. Please refer to [link / reference needed]. Figures 1-5This embodiment provides a baffle cone device for an air classifier, which can reduce the wear of the baffle cone during long-term production and break up agglomerated or clustered materials, thereby improving the accuracy and efficiency of air classification. The baffle cone device includes a baffle cone body 1. The air classifier is model TESu-310. The baffle cone body 1 is installed inside the air classifier. The outer surface of the baffle cone body 1 is the windward side, and the distance between the ceramic wear-resistant coating 3 and the windward side is one centimeter. A silicon steel mesh 2 is fixedly installed on the outside of the baffle cone body 1. The silicon steel mesh 2 is model 50*50D20 diamond-shaped. A ceramic wear-resistant coating 3 is fixedly installed on the outside of the silicon steel mesh 2. The ceramic wear-resistant coating 3 is model VALOR400 and is a ceramic wear-resistant coating. The ceramic wear-resistant coating is 50 mm thick. Applying this coating improves the wear resistance of the baffle cone body 1, preventing severe wear that could wear through the outer wear layer. A dispersing device is installed on the outer surface of the ceramic wear-resistant coating 3, with devices evenly distributed at angles. When the baffle cone body 1 rotates, the dispersing plate 402 disperses any agglomerated or clustered materials, resulting in more uniform material dispersion and improved powder selection accuracy and efficiency. The dispersing device includes a mounting block 401, a dispersing plate 402, a mounting frame 403, and a spring. 404, baffle 405, clamping rod 406, pull rod 407, and connecting plate 408; mounting block 401 is fixedly installed on the outside of ceramic wear-resistant coating 3; the mounting block 401 has an I-shaped groove inside; the dispersing plate 402 has a groove in the middle of the side near the mounting block 401, and the dispersing plate 402 is inserted into the mounting block 401 for easy installation; the dispersing plate 402 is installed inside the mounting block 401; mounting bracket 403 is fixedly installed on the outside of the mounting block 401; one end of spring 404 is fixedly installed on the mounting bracket 408. On the left and right sides of the inner wall of the mounting bracket 403, the baffle 405 is fixedly installed on the other end of the spring 404, and the locking rod 406 is fixedly installed on the side of the baffle 405 away from the spring 404. The dispersing plate 402 has a locking hole inside, and the diameter of the locking hole is equal to the diameter of the locking rod 406. The dispersing plate 402 is fixed on the mounting block 401 by locking the locking rod 406 with the locking hole. One end of the pull rod 407 is fixedly installed on the side of the baffle 405 away from the locking rod 406, and the connecting plate 408 is fixedly installed on the other end of the pull rod 407.

[0027] Example 2:

[0028] Based on Example 1, please refer to Figures 1-4 In order to improve the engagement efficiency of the locking rod 406 and the locking hole of the disintegration plate 402, the shape of the locking rod 406 is also improved. The end of the locking rod 406 away from the baffle 405 is hemispherical. The hemispherical shape makes it easier for the locking rod 406 to engage with the locking hole of the disintegration plate 402, thereby improving the installation efficiency of the disintegration plate 402.

[0029] During use, the wear resistance of the baffle cone body 1 is increased by the silicon steel mesh 2 and the ceramic wear-resistant coating 3, thereby preventing the wear-resistant layer of the outer shell from being worn through. At the same time, when the baffle cone body 1 rotates, the dispersing plate 402 disperses the agglomerated or clustered materials, making the materials more evenly dispersed, thereby improving the accuracy and efficiency of powder selection. When it is necessary to replace the dispersing plate 402, the connecting plate 408 is pulled outward to drive the pull rod 407 to pull the baffle 405 and the locking rod 406 to move, so that the locking rod 406 disengages from the locking hole opened in the dispersing plate 402. Then, the damaged dispersing plate 402 is pulled out, and the new dispersing plate 402 is inserted into the mounting block 401 and fixed to the mounting block 401 by the locking rod 406 through the new dispersing plate 402.
