[0014] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 2 As shown:
[0015] Example 1: A fine screening equipment for the production of hexagonal boron nitride includes a working box 1 with an opening at the top. Multiple sets of receiving plates 2 are arranged vertically and vertically in the working box 1, with at least three sets of receiving plates 2. A discharge pipe 3 is provided on the receiving plate 2. After the material is put onto the receiving plate 2, the material can fall onto the next layer of receiving plate 2 through the discharge pipe 3.
[0016] The feed pipe 3 on the second receiving plate 2 from the bottom and the feed pipe 3 above it are equipped with a liftable filter screen 4. The filter screen 4 makes it easy to separate materials of different diameters.
[0017] Starting from the discharge pipe 3 on the second receiving plate 2 from the bottom, there is an inclined pipe 5 extending to the outside of the working box 1. When the filtered material needs to be discharged, the filter screen 4 is moved down to be flush with the discharge port of the inclined pipe 5 so that the material can be discharged through the inclined pipe 5.
[0018] A discharge pipe 6 is provided on the lower side of the working box 1 to facilitate the discharge of the smallest diameter material after filtration. An exhaust mechanism is provided on the side of the working box 1. The exhaust mechanism is connected to the working box 1 through a pipe 7, and the pipe 7 is located under the bottom receiving plate 2.
[0019] The exhaust system allows for the removal of powdery materials, enabling further screening of powdery and small-particle materials.
[0020] Example 2: A fine screening equipment for the production of hexagonal boron nitride includes a working box 1 with an opening at the top. Multiple sets of receiving plates 2 are arranged vertically and vertically in the working box 1, with at least three sets of receiving plates 2. A discharge pipe 3 is provided on the receiving plate 2. After the material is put onto the receiving plate 2, the material can fall onto the next layer of receiving plate 2 through the discharge pipe 3.
[0021] The feeding pipe 3 is located in the middle of the receiving plate 2. The middle of the receiving plate 2 is recessed downward to facilitate the material to slide into the feeding pipe 3.
[0022] The feed pipe 3 on the second receiving plate 2 from the bottom and the feed pipe 3 above it are equipped with a liftable filter screen 4. The filter screen 4 makes it easy to separate materials of different diameters.
[0023] The upper side of the work box 1 is provided with an electric telescopic rod 9 vertically mounted via a support rod 8, and a vertically mounted lifting rod 10 is provided at the telescopic end of the electric telescopic rod 9. The filter screen 4 is connected to the lifting rod 10.
[0024] Starting from the discharge pipe 3 on the second receiving plate 2 from the bottom, there is an inclined pipe 5 extending to the outside of the working box 1. The inclined pipe 5 is equipped with a slide valve 16. When the filtered material needs to be discharged, the filter screen 4 is moved down to be flush with the discharge port of the inclined pipe 5 so that the material can be discharged through the inclined pipe 5.
[0025] A discharge pipe 6 is provided on the lower side of the working box 1 to facilitate the discharge of the smallest diameter material after filtration. An exhaust mechanism is provided on the side of the working box 1. The exhaust mechanism is connected to the working box 1 through a pipe 7, and the pipe 7 is located under the bottom receiving plate 2.
[0026] The ventilation mechanism includes a fan 11, which is connected to a material box 13 through a first pipe 12. The bottom of the material box 13 is provided with a discharge pipe. A partition net 15 is provided in the material box 13 to separate the first pipe 12. The material box 13 is connected to the working box 1 through a pipe 7 on the opposite side of the first pipe 12.
[0027] The exhaust system allows for easy removal of powdery materials, thus enabling further screening of powdery materials and smaller particles.
[0028] All of the above components are controlled by a controller.
[0029] Working principle:
[0030] The material to be screened is placed on the first receiving plate 2. When the material passes through the filter screen 4, larger particles can be intercepted. The multi-layer receiving plate 2 makes it easy to separate the material according to size. If the filter screen 4 is clogged, the clogged material can be shaken down by lifting the filter screen 4. The filter screen 4 moves down to be horizontal with the inclined tube 5, which makes it easy to discharge the material from the receiving plate 2. When the smallest diameter material is filtered out and falls to the bottom of the working box 1 from the bottom feed pipe 3, the exhaust mechanism can separate the powdery material from the smaller particles, making it easy to draw them into the material box 13 and discharge them from the discharge pipe.
[0031] 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.
