[0016] In order to more clearly illustrate the technical scheme of the embodiments of the utility model, the drawings needed to be used in the embodiment description will be briefly introduced as follows, and obviously, the drawings in the following description are some embodiments of the utility model, and other drawings can also be obtained according to these drawings without creative labor for those skilled in the art.
[0017] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from the description, therefore, the utility model is not limited to the specific embodiments disclosed in the following description.
[0018] Embodiment 1, as Figure 1 , Figure 2The embodiment aims to solve the problem of easy damage of the screen caused by friction during the vibration sorting of white corundum. Considering that the hardness of white corundum is high, only the condition of increasing other substances can reduce friction. Therefore, the white corundum grinding section sand device comprises a storage cylinder 1 and a sorting screw 2 arranged below the storage cylinder 1. In the embodiment, the storage cylinder 1 is in the form of a cylinder with an open top. Therefore, the storage cylinder 1 comprises a cylinder body 11 and a rotating shaft 12 arranged in the cylinder body 11. The rotating shaft 12 is located at the center of the cylinder body 11. The sorting screw 2 is a spiral channel with a certain height. When the water flow and the object move downward from the upper part of the spiral channel, the heavy objects move to the inside of the sorting screw 2 under the action of gravity and centrifugal force, and the light objects move to the outside due to the light weight. At this time, only different receiving grooves need to be arranged at the bottom of the sorting screw 2.
[0019] Therefore, in the embodiment, the side wall of the rotating shaft 12 is provided with a partition plate 13. The partition plate 13 is uniformly distributed on the side wall of the rotating shaft 12. In this way, the partition plate 13 divides the storage cylinder 1 into a plurality of annular storage cavities. The main purpose of the storage cavity is to store the mixture of water and white corundum. Of course, in order to discharge, a discharge port 14 is arranged at the bottom of any storage cavity. The discharge port 14 is arranged above the sorting screw 2. In addition, the upper part of the storage cavity with the discharge port 14 is provided with a grinding material inlet pipe 6 or a water inlet pipe 5. In the embodiment, there are eight partition plates 13, which are divided into eight storage cavities. According to the rotation direction of the partition plate 13, five water inlet pipes 5 are arranged first, and two grinding material inlet pipes 6 are arranged near the discharge port 14. In this way, a large amount of water is filled in the storage cavity. When the grinding material enters the storage cavity, it is subjected to water resistance, which will not cause damage to the bottom of the cylinder body 11. In this way, under the continuous rotation of the rotating shaft 12, the mixture of water and white corundum continuously falls from the sorting screw 2, so as to realize the sorting of white corundum.
[0020] In order to further improve the sorting effect, a guide plate 3 is arranged on the sorting screw 2 in the embodiment. A guide channel 4 is arranged outside the sorting screw 2. The guide plate 3 and the guide channel 4 are connected and arranged. The sorting screw 2 is provided with a gap 21 communicating with the guide channel 4. In this way, the guide plate 3 forms more levels of material distribution of white corundum.
[0021] Considering that the white corundum needs to fall a certain distance before it can be distributed, the guide plate 3 is arranged near the lower part of the sorting screw 2. In this way, the white corundum is classified as much as possible before being sorted.
[0022] Similarly, in order to more levels of distribution, at least two staggered guide plates 3 are arranged on the sorting screw 2. In the embodiment, two staggered guide plates 3 are arranged. In order to facilitate the movement of the abrasive on the guide channel 4, the guide surface of the guide channel 4 is inclined downward in the embodiment.
[0023] In this way, the whole set of equipment relative to the original vibration screening, only a water pump and a driving motor can be completed, and the abrasive separated by the guide channel 4 and the sorting screw 2 can be dried by using the heat generated in the production of white corundum after removing the water by the filter screen, so that the subsequent washing process is saved.
[0024] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application still belongs to the protection scope of the technical scheme of the present application.
