The production process of diamond, especially the production of synthetic diamond, is a complex and delicate process. When producing diamond, it is necessary to remove small particle diamonds and other impurities. Therefore, a sand screening device is needed to screen diamonds.

[0003] However, there are some problems in the prior art: When the existing diamond sand screening device screens diamonds, the size of the diamonds may be equivalent to the size of the sieve holes of the sieve plate, resulting in these diamonds blocking the sieve holes during screening, causing incomplete screening of the diamonds or even unable to screen. Therefore, we propose an anti-blocking sand screening device. Summary of the Utility Model

[0024] In order to further understand the content, features and effects of the present utility model, the following embodiments are cited and described in detail in conjunction with the accompanying drawings as follows.

[0025] As Figures 1 to 5As shown in the figure, an anti-clogging sand screening device provided by an embodiment of the present utility model includes a base 1. The base 1 is made of stainless steel material and is welded by multiple groups of steel plates. The main function of the base 1 is to support the entire device.

[0026] A bracket 2 is fixedly connected to the upper end of the base 1. The bracket 2 is made of stainless steel material and has high strength to ensure that the sand screening cylinder 3 can rotate stably. The sand screening cylinder 3 is rotatably connected to the bracket 2. Two groups of limit rings 9 are fixedly connected to the bracket 2. The two ends of the sand screening cylinder 3 are respectively rotatably connected to the two groups of limit rings 9. The limit rings 9 are used to limit the movement of the sand screening cylinder 3.

[0027] The limit rings 9 are adapted to the size of the sand screening cylinder 3. The limit rings 9 are also made of high-strength stainless steel material. Its main function is to prevent the sand screening cylinder 3 from disengaging during rotation. Usually, a bearing is provided between the limit rings 9 and the sand screening cylinder 3 to reduce the friction between the limit rings 9 and the sand screening cylinder 3.

[0028] The sand screening cylinder 3 is provided with screening holes for screening diamonds. A cleaning component 4 is provided on the bracket 2. The cleaning component 4 includes a fixed block 401. The fixed block 401 is fixedly connected to the limit ring 9. A rotating shaft 402 is rotatably connected to the fixed block 401. A cleaning wheel 403 is fixedly connected to the rotating shaft 402. The cleaning wheel 403 corresponds to the screening holes on the sand screening cylinder 3.

[0029] The cleaning wheel 403 is provided with teeth meshing with the screening holes. When the sand screening cylinder 3 rotates, it will drive the cleaning wheel 403 and the rotating shaft 402 to rotate on the fixed block 401. At this time, the cleaning wheel 403 will push out the diamonds blocked in the screening holes of the sand screening cylinder 3 through the teeth. At the same time, the screening holes will also drive the cleaning wheel 403 to rotate, and the next tooth of the cleaning wheel 403 corresponds to the next screening hole of the sand screening cylinder 3, so as to clean all the diamonds blocked in the screening holes of the sand screening cylinder 3 in a cyclic manner, avoiding the blocked diamonds from affecting the screening of diamonds.

[0030] A driving component 5 is provided on the base 1. The driving component 5 is used to drive the sand screening cylinder 3 to rotate. The driving component 5 includes a first motor 501. The first motor 501 is fixedly connected to the base 1. A gear 502 is fixedly connected to the output end of the first motor 501.

[0031] After the first motor 501 is started, it drives the gear 502 to rotate. The gear 502 drives the meshing toothed ring 503 to rotate. After the toothed ring 503 rotates, it will drive the sand screening cylinder 3 to rotate, so that the diamonds in the sand screening cylinder 3 roll to complete screening. At the same time, the sand screening cylinder 3 has a certain inclination angle. When screening diamonds, the larger particles of diamonds in the sand screening cylinder 3 will gradually move downward and finally fall out of the sand screening cylinder 3 and into the aggregate box 801 for collection.

[0032] A groove is formed at the upper end of the base 1. A feeding plate 6 is movably connected in the groove. A placement groove is formed in the inner wall of the groove of the base 1. A second motor 10 is fixedly connected to the inner wall of the placement groove.

A hole is formed at one end of the feeding plate 6, and a fixing rod 13 is rotatably connected in the hole. The fixing rod 13 is fixedly connected to the inner wall of the groove of the base 1.

[0034] After the second motor 10 is started, it will drive the first crankshaft 11, and the feeding plate 6 will vibrate with the rotation of the first crankshaft 11 through the second crankshaft 12 and the fixing rod 13, so that the diamonds on the feeding plate 6 vibrate, and then the diamonds are evenly distributed and can enter the sand screening cylinder 3 orderly for screening, avoiding excessive diamonds entering at the same time, resulting in incomplete screening and clogging of the screening holes of the sand screening cylinder 3.

[0035] A storage tank 7 is fixedly connected to the upper end of the base 1. The storage tank 7 is funnel-shaped and made of stainless steel. The main function of the storage tank 7 is to store the diamond raw materials that have not been screened. An outlet is formed at the lower end of the storage tank 7 for supplying diamonds to the feeding plate 6.

[0036] A collection assembly 8 is arranged on the base 1. The collection assembly 8 includes an aggregate box 801 and a miscellaneous collection box 802. The aggregate box 801 is fixedly connected to one side of the base 1. An aggregate groove is formed on the base 1. The miscellaneous collection box 802 is movably connected in the aggregate groove. Both the aggregate box 801 and the miscellaneous collection box 802 are made of stainless steel. The aggregate box 801 is used to collect the large-particle diamonds after screening, and the miscellaneous collection box 802 is used to collect small-particle diamonds and impurities.

[0037] A control console 14 is fixedly connected to one side of the base 1. The control console 14 includes components such as an electrical control cabinet and a touch screen, and is used to control the operating parameters of the sand screening device, such as the rotation speed of the motor, the screening time, etc.

Compared with a sieve plate, the sand screening cylinder 3 needs to keep rotating all the time during screening, and the diamonds blocked in the screening holes will be rotated to the upper part. Some of the blocked diamonds can fall off from the screening holes due to their own gravity, avoiding blocking the screening holes.

[0040] The utility model is provided with a cleaning component 4. The diamonds that do not fall off by their own gravity will rotate to the upper part along with the sand screening cylinder 3. At this time, the cleaning wheel 403 will push out the diamonds in the sieve holes, so that the sieve holes will no longer be blocked. At the same time, the cleaning wheel 403 will rotate along with the rotation of the sand screening cylinder 3, so as to clean the blocked diamonds in a cycle and avoid the blockage of the sieve holes.

[0041] The utility model is provided with a feeding plate 6 movably connected to the base 1. The second motor 10 drives the first crankshaft 11 to rotate, so that the feeding plate 6 vibrates, and then the diamonds on the feeding plate 6 are evenly distributed, and can enter the sand screening cylinder 3 orderly for screening, avoiding excessive diamonds entering at the same time, resulting in incomplete screening and blockage of the sieve holes of the sand screening cylinder 3.
