Description

Technical Field

[0001] This utility model relates to the field of powder classifier technology, and in particular to a wear-resistant multi-stage powder classifier for sand making. Background Technology

[0002] Dry sand making is a process for producing manufactured sand by crushing rocks. Its core processes include coarse crushing, medium crushing, sand making, and powder selection.

[0003] In the existing technology, after the rock is crushed, the crushed sand particles are stored due to the difference in crushing and powder selection efficiency. If the storage environment is humid, the sand particles will clump together when there is moisture in the rock. During powder selection, the clumps of sand particles exert a large force on the screen and have great friction. If the clumps of sand particles are not cleaned in time, the screen will be worn and the powder selection accuracy will be reduced. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that after crushing rocks, due to the difference in crushing and powder selection efficiency, the crushed sand particles are stored. However, if the storage environment is humid, the sand particles will clump together when there is moisture in the rocks. During powder selection, the clumps of sand particles exert a large force on the screen and cause great friction. If the clumps of sand particles are not cleaned in time, the screen will be worn and the powder selection accuracy will be reduced. Therefore, this invention proposes a wear-resistant multi-stage powder selection equipment for sand making.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant multi-stage sand making and classifying device, comprising a classifying box, a sealing cover fixedly connected to the upper end of the classifying box, a drive motor fixedly connected to the upper middle part of the sealing cover, an assembly plate fixedly connected to the output end of the drive motor, a striking rod and an inclined blade fixedly connected to the outer surface of the assembly plate, and a feed inlet fixedly connected to the upper end of the sealing cover and on both sides of the drive motor, the inclined blade and the striking rod covering the lower end of the feed inlet to ensure complete contact with the sand particles and avoid leakage.

[0006] Preferably, a limiting inner ring is fixedly connected inside the powder selection box, and a screen holder is provided above the limiting inner ring, with the outer ring surface of the screen holder fitting against the inner ring surface of the powder selection box.

[0007] Preferably, an inner support rod is fixedly connected to the upper center of the screen base, and a powder-selecting mesh is fixedly connected to the upper end of the screen base, with a gap between the upper end of the inner support rod and the powder-selecting mesh.

[0008] Preferably, the powder sorting screen is inclined, and a second discharge port is fixedly connected to one side of the powder sorting box. The lower end of the inner side of the second discharge port coincides with the bottom end of the upper surface of the powder sorting screen.

[0009] Preferably, a guide plate is fixedly connected inside the powder sorting box and below the limiting inner ring. The guide plate is tilted in the opposite direction to the powder sorting screen, and the tilt angle of the guide plate is greater than that of the powder sorting screen.

[0010] Preferably, a No. 1 discharge port is fixedly connected to the other side of the powder classifier, the lower end face of the inner side of the No. 1 discharge port coincides with the bottom end of the upper surface of the guide inclined plate, and a vibration motor is fixedly connected to the middle of the lower end of the powder classifier.

[0011] Preferably, end seats are fixedly connected to the middle of both sides of the powder classifier body, and reinforcing ribs are fixedly connected between the upper end of the end seat and the powder classifier body. A supporting base plate is provided below the end seat, and a spring is installed between the supporting base plate and the end seat. Inner limiting sleeves are fixedly connected to the middle of the upper end of the supporting base plate and the middle of the lower end of the end seat, and the spring is sleeved and fixed to the inner limiting sleeve.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the striking rod can break up agglomerated sand particles by striking them. The inclined blades can cause airflow through their inclined surfaces, which in turn causes airflow inside the classifier box. Combined with the vibration of the vibrating motor, this can accelerate the classification efficiency of sand particles. It is easy to use. At the same time, centrifugal force can be used to make sand particles impact the inner wall of the classifier box, breaking up smaller agglomerated sand particles. In this way, friction only acts on the inclined blades and striking rods. When the inclined blades and striking rods are worn to the point of being unusable, they can be replaced. This will not put too much force on the classifier screen, reduce the wear of the classifier screen, increase its service life, and ensure the classification effect.

[0014] 2. In this utility model, the deformation range of the powder classifier is limited by the setting of the inner support rod, which prevents the powder classifier from bending excessively and ensures its service life. The setting of the limiting inner ring allows the screen holder to be installed in an overlapping manner, which makes disassembly and assembly more convenient. At the same time, the powder classification operation is carried out by combining vibration and micro-airflow, which can reduce the scattering range of powder-grade sand particles, making it safer to use. The flow of micro-airflow can promote the flow of sand particles from the feed inlet and from the powder classifier, avoiding blockage and improving the powder classification effect.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-3 As shown, this utility model provides a wear-resistant multi-stage sand making and classifying equipment, including a classifying box 1. A sealing cover 4 is fixedly connected to the upper end of the classifying box 1. A drive motor 6 is fixedly connected to the middle of the upper end of the sealing cover 4. An assembly plate 18 is fixedly connected to the output end of the drive motor 6. A striking rod 17 and an inclined blade 19 are fixedly connected to the outer surface of the assembly plate 18. A feed inlet 5 is fixedly connected to the upper end of the sealing cover 4 and on both sides of the drive motor 6. The inclined blade 19 and the striking rod 17 cover the lower end of the feed inlet 5 to ensure complete contact with the sand particles and avoid leakage.

[0022] The specific settings and functions of this embodiment are described in detail below. The striking rod 17 can be used to strike and break up agglomerated sand particles. The inclined blade 19 can cause airflow through its inclined surface, which in turn causes airflow inside the classifier 1. Combined with the vibration of the vibration motor 7, the classifier efficiency can be accelerated, making it more convenient to use. At the same time, centrifugal force can be used to make the sand particles impact the inner wall of the classifier 1, breaking up smaller agglomerated sand particles. In this way, friction only acts on the inclined blade 19 and the striking rod 17. When the inclined blade 19 and the striking rod 17 are worn to the point of being unusable, they can be replaced. This will not exert a large force on the classifier 16, reducing the wear of the classifier 16, increasing its service life, and ensuring the classifier effect.

[0023] Example 2: Figures 1-3 As shown, a limiting inner ring 13 is fixedly connected inside the powder classifier 1. A screen holder 14 is provided above the limiting inner ring 13. The outer ring surface of the screen holder 14 is in contact with the inner ring surface of the powder classifier 1. An inner support rod 15 is fixedly connected to the upper middle part of the screen holder 14. A powder classifier 16 is fixedly connected to the upper end of the screen holder 14. A gap is left between the upper end of the inner support rod 15 and the powder classifier 16. The powder classifier 16 is inclined. A second discharge port 3 is fixedly connected to one side of the powder classifier 1. The lower end of the inner side of the second discharge port 3 coincides with the bottom end of the upper surface of the powder classifier 16. A guide inclined plate 20 is fixedly connected inside the powder classifier 1 and below the limiting inner ring 13. The inclined direction of the guide inclined plate 20 is opposite to that of the powder classifier 16. The inclined angle of the guide inclined plate 20 is greater than that of the powder classifier 16. On the other side, a discharge port 2 is fixedly connected. The lower end face of the inner side of discharge port 2 coincides with the bottom end of the upper surface of the guide inclined plate 20. A vibration motor 7 is fixedly connected to the middle of the lower end of the powder classifier 1. End seats 10 are fixedly connected to the middle of both sides of the powder classifier 1. A reinforcing rib 11 is fixedly connected between the upper end of the end seat 10 and the powder classifier 1. A support base plate 8 is provided below the end seat 10. A spring 9 is installed between the support base plate 8 and the end seat 10. An inner limiting sleeve 12 is fixedly connected to the middle of the upper end of the support base plate 8 and the middle of the lower end of the end seat 10. The spring 9 is sleeved and fixed to the inner limiting sleeve 12. The number of powder classifiers 16, screen holders 14 and limiting inner rings 13 is set according to the requirements to perform multi-stage powder classification. The limiting inner rings 13 are installed and fixed to the powder classifier 1 with bolts and can be disassembled and assembled as needed.

[0024] The overall effect of this embodiment is that the deformation range of the powder classifier 16 is limited by the inner support rod 15, which prevents the powder classifier 16 from bending excessively and ensures its service life. The inner limiting ring 13 allows the screen holder 14 to be installed in an overlapping manner, making disassembly and assembly more convenient. At the same time, the powder classifier operation is carried out by combining vibration and micro-airflow, which can reduce the scattering range of powder-grade sand particles, making it safer to use. Furthermore, the flow of micro-airflow can promote the outflow of sand particles from the feed inlet 5 and the flow of sand particles from the powder classifier 16, avoiding blockage and improving the powder classifier effect.

[0025] The usage method and working principle of this device are as follows: When in use, the sand particles to be selected are placed into the feed inlet 5. The sand particles are broken by the striking rod 17 and the inclined blade 19, so that the clumps of sand particles are dispersed and fall onto the powder selection screen 16. The vibration of the vibrating motor 7 and the airflow caused by the inclined blade 19 promote the movement of the sand particles and carry out powder selection processing. The larger sand particles are discharged from the second discharge port 3, and the powder flows out from the first discharge port 2.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
