[0012] Beneficial effects

[0013] This utility model provides a tailings belt separator with the following advantages: This solution uses a dry-type vibrating separator structure, changing the structure of traditional separators. The conveyor section uses a PVC conveyor belt and is equipped with baffles for ore screening. The vibration structure enables automatic grading and conveying of tailings, improving sorting efficiency. It also supports continuous operation and reduces manual intervention. The screen-type uniform grouting component ensures uniform grout distribution, avoids local accumulation or blockage, and improves sorting accuracy. This solves the problem that existing tailings screening often uses blanket tailings separators, which suffer from uneven grouting and cannot guarantee accurate screening. Furthermore, the conveyor belt is made of blanket, and the fine pores on the blanket surface easily adsorb some ore, causing waste ore to be collected into the recovery box during screening, affecting the tailings recovery rate and concentrate quality.

Detailed Implementation

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example: Please refer to Figures 1-4 This utility model provides a technical solution: a tailings belt separator. This solution takes into account that existing tailings separators cannot completely and accurately screen different mineral sands due to their structure, resulting in waste mineral sands entering the concentrate recovery box. Furthermore, uneven grouting can easily cause grout blockage, affecting tailings separator efficiency and recovery quality. Based on the above, this invention sets up the following technical means.

[0021] Specifically, this device includes at least: equipment base 1, a pair of fixed base rods 2, two pairs of support rods 3, swaying frame 4, two pairs of fixed brackets 5, several mounting rods 6, screening conveyor belt 7, several fine selection rods 8, support frame 9, grouting box 10, screen-type uniform grouting assembly, concentrate collection box 11, and tailings sand collection box 12.

[0022] The sieve-type uniform grouting assembly includes: a grouting chamber 16, several grouting holes 17, a material injection pipe 18, a water injection pipe 19, a pair of diversion flushing pipes 20, a grout discharge frame 21, a pair of mounting brackets 22, a pair of flushing boxes 23, a connecting water pipe 24, and a pair of flushing pipes 25.

[0023] The equipment base 1 provides overall support for the equipment. During use, the injection pipe 18 is connected to the external feeding structure, and the water injection pipe 19 is connected to the water supply system. The mortar is injected into the injection chamber 16 inside the injection box 10 through the injection pipe 18. The mortar is evenly discharged downwards through the injection hole 17 at the bottom of the injection box 10 and conveyed to the screening conveyor belt 7 through the discharge frame 21. The screening conveyor belt 7 rotates counterclockwise towards the concentrate collection box 11. At the same time as the mortar injection, the water injection pipe 19 starts to inject water simultaneously, and the water flows evenly downwards through the diversion flushing pipe 20 connected to it. The slurry flows downward through the discharge frame 21 and continuously washes the slurry on the screening conveyor belt 7. At the same time, the vibration motor 14 installed on the shaking frame 4 starts and drives the shaking frame 4 to shake on the support rod 3 with the support spring 13. During the shaking, the heavier concentrate sinks downward and is blocked by the selection baffle 8 set on the screening conveyor belt 7. Due to the shaking and the impact of the water flow, the waste sand flows to the right and is discharged into the tailings sand collection box 12. The screened concentrate falls into the concentrate collection box 11 through the screening conveyor belt 7 and the selection baffle 8, thereby achieving efficient tailings screening.

[0024] In this technical solution, both the diversion flushing pipe 20 and the flushing pipe 25 are provided with drainage holes.
