Description

Technical Field

[0001] The utility model relates to the technical field of coating material processing, in particular to a coating material circulation crushing mechanism. Background Art

[0002] Coating materials usually include ceramic coatings, metal coatings, polymer coatings and composite coating materials. For example, ceramic coating materials such as alumina, zirconia and other ceramic powders may form larger particles during the preparation process, which need to be crushed to achieve a finer and more uniform particle size, thereby improving the density and performance of the coating. For example, in the thermal barrier coating of aircraft engines, small and uniform ceramic particles can better resist high temperatures and thermal shocks. In the production process of alumina powder, a crushing device is required to crush it, and then grind, extract, calcine and other multi-step processing is performed to facilitate subsequent use.

[0003] For example, the utility model with application number 202322382923.5 discloses a high-purity alumina crushing device. The utility model pours the high-purity alumina to be crushed into a loading hopper, and drops it from the bottom of the loading hopper into the inside of a sleeve under the action of gravity. The third motor is started and maintained at a certain speed to drive the first turntable to rotate, so that the first fixed pin rotates with the first turntable. While one end of the first transmission rod rotates along the first fixed pin, the first transmission rod pushes the push rod to continuously reciprocate along the inside of the sleeve, so that the push rod pushes the high-purity alumina raw material inside the sleeve into the guide bin, so that the high-purity alumina raw material falls into the casing through the guide bin, which is beneficial to control the feeding speed of the high-purity alumina and avoid blockage during crushing.

[0004] Similar to the above application, there are still some shortcomings:

[0005] This type of high-purity alumina crushing device can only crush the material once, and cannot cyclically crush the alumina material. During the crushing process, some materials that have not been crushed into small particles will directly enter the next step, causing inconvenience to the subsequent refinement processing work. Manually collecting large particles and putting them into the crusher for further crushing increases the workload of the staff, brings inconvenience to the crushing work, and reduces the crushing efficiency.

[0006] Therefore, a coating material circulation crushing mechanism is designed to optimize the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0026] like Figure 1-Figure 4As shown, the present embodiment provides a coating material circulation crushing mechanism, including a shell 1, a maintenance door is provided on the outer side of the shell 1, and a handle is provided on the outer side of the maintenance door, and maintenance and use work are conveniently performed through the maintenance door, an outer cylinder 2 is rotatably installed inside the shell 1, bearings are provided on the outer sides of both ends of the outer cylinder 2, and the outer rings of the bearings are fixedly connected to the inner side walls of the shell 1, and the bearings are further used to further improve the supporting force of the outer cylinder 2, while reducing the rotational friction between the outer cylinder 2 and the shell 1, a first filter port 3 is evenly provided on the outer side of the outer cylinder 2, and push plates 12 are evenly distributed in an annular shape inside the outer cylinder 2, an inner cylinder 8 is rotatably installed inside the outer cylinder 2, and one end of the inner cylinder 8 penetrates and extends to the outer side of the shell 1, and one end of the inner cylinder 8 is fixedly connected to the shell 1, and both ends of the outer cylinder 2 are sleeved with outer gear rings 4, and a motor 5 is installed on the outer side of the shell 1. The output shaft of the machine 5 is fixed with a rotating shaft 6, and partitions 23 are symmetrically arranged inside the outer shell 1, and connection ports are opened at the connections between the partitions 23, the outer cylinder 2 and the rotating shaft 6. The setting of the partition 23 vertically divides the interior of the outer shell 1 into three spaces, so that the outer toothed ring 4 and the gear 7 outside the outer cylinder 2 respectively block the space at both ends of the outer cylinder 2, thereby reducing the dust and impurities in the crushing process from entering the gear 7 and the outer toothed ring 4, causing pollution and affecting the operation of the outer toothed ring 4 and the gear 7. The outer side of the rotating shaft 6 is evenly sleeved with gears 7 respectively meshing with the outer toothed ring 4, and the end of the inner cylinder 8 away from the outer cylinder 2 is symmetrically installed with motors 2 13, and the output shafts of the motors 2 13 are fixed with crushing rollers 14. A feed port 10 is opened at the top of the inner cylinder 8, a discharge port 11 is opened at the bottom of the inner cylinder 8, and a feed hopper 9 is installed at the top of the end of the inner cylinder 8 away from the outer cylinder 2.

[0027] Specifically, the coating material is poured from the feed hopper 9 and enters the inner cylinder 8 and between the crushing rollers 14 through the feed port 10. The crushing rollers 14 are driven by the motor 2 13 to rotate relatively to crush the material. The crushed material falls through the discharge port 11 and falls into the inner part of the outer cylinder 2. The small particles of material fall to the outside of the outer shell 1 through the first filter port 3. The oversized particles of material are intercepted in the inner part of the outer cylinder 2. The motor 15 drives the rotating shaft 6 and the gear 17 to rotate. The gear 17 drives the outer cylinder 2 and the push plate 12 to rotate through the outer gear ring 4, and the large particles of material in the outer cylinder 2 are pushed to the position of the feed port 10 and fall again between the crushing rollers 14 for cyclic crushing. The inner cylinder 8 is blocked to reduce the damage to the crushing roller 14 caused by the material stuck on the outside of the crushing roller 14 during the material circulation pushing process, thereby protecting the outside of the crushing roller 14 and facilitating the centralized pushing of materials, thereby reducing the problem of large particles of material not being circulated and crushed due to leakage.

[0028] like Figure 1 and Figure 3As shown, a sleeve 15 is provided on the outer side of the outer cylinder 2 for sliding, and a second filter port 20 is evenly provided on the outer side of the sleeve 15. Movable rings 16 are fixed at both ends of the sleeve 15. Fixed rings 17 are symmetrically installed on the outer side of the outer cylinder 2. A screw 19 is rotatably installed between the fixed rings 17. A grip block is provided on the outer side of the screw 19, and anti-slip grooves are evenly provided on the outer side of the grip block. The grip block and the anti-slip grooves facilitate the rotation of the screw 19 by the staff. A limit rod 18 is symmetrically installed between the fixed rings 17, and the limit rod 18 penetrates and extends to the outer side of the movable ring 16. The movable ring 16 is slidably connected to the limit rod 18, the screw 19 penetrates the movable ring 16 and extends to the outer side of the movable ring 16, and the screw 19 is threadedly connected to the movable ring 16.

[0029] Specifically, by rotating the screw 19, under the limitation of the limiting rod 18, the sleeve 15 and the outer cylinder 2, the screw 19 drives the movable ring 16 and the sleeve 15 to move horizontally, so that the second filter port 20 on the sleeve 15 moves at the same time, and the size of the overlapping part between the first filter port 3 and the second filter port 20 on the outer cylinder 2 is adjusted. The larger the overlapping part, the larger the particles that can pass through, and the smaller the overlapping part, the smaller the particles that can pass through.

[0030] like Figure 2 As shown, a support rod 21 is rotatably mounted inside the housing 1 and in a position horizontally aligned with the rotating shaft 6 , and gears 22 are evenly arranged on the support rod 21 , and the gears 22 are meshed with the outer gear ring 4 .

[0031] Specifically, while gear 1 7 drives the outer gear ring 4 and the outer cylinder 2 to rotate, the outer gear ring 4 drives gear 2 22 and the support rod 21 to rotate. At the same time, the support rod 21 and gear 2 22 support the bottom of the outer cylinder 2, dispersing part of the weight of the outer cylinder 2 and sharing the load-bearing of the rotating shaft 6 and gear 1 7.

[0032] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
