[0026] As Figures 1-5As shown, a kind of sandstone processing sedimentation equipment, including separation screw conveyor 1, the surface of separation screw conveyor 1 is provided with access component 2, the surface of access component 2 is provided with sedimentation cone 3, the surface of sedimentation cone 3 is provided with overflow component 4 for water separation when sinking, the top surface of overflow component 4 is provided with top cover 5, top cover 5 is provided with liquid inlet pipe 6, top cover 5 is provided with stirring component 7, the inner wall of sedimentation cone 3 is fixedly connected with lap joint frame 8, the top surface of lap joint frame 8 is movably connected with metal plate 9, and metal plate 9 is attached to the inner wall of sedimentation cone 3, water leakage hole 10 is formed in the surface of metal plate 9, and the top surface of metal plate 9 is fixedly connected with partition block 11, the surface of sedimentation cone 3 is provided with drain pipe 12;Specifically, the sandstone processing sedimentation equipment, the mixed liquid containing sandstone is connected with liquid inlet pipe 6 by external pumping equipment.Open pumping equipment, mixed liquid is pumped into sedimentation cone 3 through liquid inlet pipe 6.Mixed liquid first flows to the surface of partition block 11, under the guidance of partition block 11, water flows to water leakage hole 10.Mixed liquid will not directly fall into the bottom of sedimentation cone 3 because water is blocked by metal plate 9 and separated into multiple water flows by multiple water leakage holes 10, which greatly reduces the flow impact force and avoids interference with the subsequent sedimentation process in the equipment.Stirring and sedimentation: while mixed liquid enters sedimentation cone 3, stirring component 7 makes sandstone not accumulate on metal plate 9.Drainage and overflow: during sandstone sedimentation, water and sandstone flow downward through water leakage hole 10 on metal plate 9, and then are discharged from the equipment through drain pipe 12 after being collected at the bottom of sedimentation cone 3.At the same time, part of the water rises to overflow component 4, and the water is separated outward, further improving the separation effect of water and sandstone.Discharge: after sandstone is settled to a certain extent, start separation screw conveyor 1 to separate the settled sandstone outward, thereby realizing the sedimentation and separation process of the entire sandstone processing.

[0027] As Figure 1 shown, access component 2 includes feed pipe 201, the surface of separation screw conveyor 1 is provided with feed pipe 201, and the top surface of sedimentation cone 3 and feed pipe 201 is fixedly connected, the surface of separation screw conveyor 1 is provided with discharge pipe 202;Specifically, the setting of access component 2, sandstone will accumulate in feed pipe 201, start separation screw conveyor 1, sandstone can be conveyed upward, and then sandstone can be discharged outward through discharge pipe 202.

[0028] As Figure 3 , Figure 4As shown, the overflow assembly 4 comprises an overflow sleeve 401, the surface of the settling cone 3 is fixedly sleeved with the overflow sleeve 401, and the top cover 5 is fixedly connected with the top surface of the overflow sleeve 401, and the bottom surface of the overflow sleeve 401 is provided with an overflow pipe 402; Specifically, the overflow assembly 4 is provided, which can separate the water in the settling process outward, thereby improving the separation efficiency. Since the mixed liquid continuously enters the inside of the settling cone 3 through the liquid inlet pipe 6, if the liquid level height of the mixed liquid is greater than the height of the settling cone 3, at this time the water will flow into the overflow sleeve 401, and then be discharged outward through the overflow pipe 402.

[0029] As shown in Figure 3 , Figure 4 , the stirring assembly 7 comprises a motor 701, the top cover 5 is provided with the motor 701, the output end of the motor 701 is fixedly connected with a connecting rod 702, and the connecting rod 702 is rotatably connected with the top cover 5, and the surface of the connecting rod 702 is fixedly connected with a stirring blade 703; Specifically, the stirring assembly 7 is provided to stir the sand and stones remaining on the metal plate 9, so that the sand and stones will not accumulate on the metal plate 9. Start the motor 701, the output end of the motor 701 drives the connecting rod 702 to rotate, the connecting rod 702 drives the stirring blade 703 to stir the surrounding mixed liquid, and then the sand and stones remaining on the metal plate 9 are stirred with the mixed liquid, so that the sand and stones will not accumulate on the metal plate 9.

[0030] As shown in Figure 2 , the top surface of the top cover 5 is fixedly connected with a fixed cross beam 13, and the surface of the fixed cross beam 13 is provided with a lifting hole 14; Specifically, the fixed cross beam 13 is installed and fixed on the top cover 5, and the lifting hole 14 is provided, which can be connected with the lifting equipment, and then the top cover 5 can be fixed on the overflow sleeve 401 for use.

[0031] As shown in Figure 4 , Figure 5 , the water leakage hole 10 has a hole diameter greater than the particle size of the sand and stones, and the water leakage holes 10 are uniformly distributed on the surface of the metal plate 9; Specifically, the water leakage hole 10 has a hole diameter greater than the particle size of the sand and stones, which can ensure that the sand and stones can pass through the water leakage hole 10, and the uniform distribution can make the metal plate 9 bear force more evenly, reduce the risk of deformation and damage caused by excessive local stress, prolong the service life of the metal plate 9, and ensure the overall structural stability of the equipment.

[0032] In summary: equipment preparation: check whether the spiral blade of the separation spiral conveyor 1 is intact, whether the rotation is smooth, and whether there is jam. Check whether the overflow sleeve 401 and the overflow pipe 402 of the overflow assembly 4 are connected tightly, and whether there is a risk of leakage. Confirm that the top cover 5 is installed in place, the liquid inlet pipe 6 is connected normally, the motor 701 in the stirring assembly 7 is electrically connected correctly and has good performance. Place the metal plate 9 on the lap joint frame 8 so that it is tightly attached to the inner wall of the settling cone 3, and check whether the water leakage hole 10 is blocked. Finally, check whether the drain pipe 12 is connected properly to ensure smooth drainage. Feeding stage: connect the mixed liquid containing sand and gravel to the liquid inlet pipe 6 through the external conveying pipeline, start the conveying pump, and make the mixed liquid flow slowly into the settling cone 3. Stirring and separation stage: start the motor 701 in the stirring assembly 7, and after the motor 701 is powered on, its output end drives the connecting rod 702 to rotate, which in turn drives the stirring blade 703 to rotate in the settling cone 3. The rotation of the stirring blade 703 stirs the sand and water that stays on the metal plate 9, so that the sand does not accumulate too much on the metal plate 9. In this process, the sand gradually overcomes the resistance and buoyancy of water and begins to settle under the action of gravity. Settlement and drainage stage: as the stirring proceeds, the sand continuously settles to the bottom of the settling cone 3 through the water leakage hole 10. After the water and sand collect at the bottom of the settling cone 3, open the drain pipe 12, and the water can be discharged from the device through the drain pipe 12. At the same time, during the process of mixed liquid entering, a small amount of water rises to the overflow assembly 4, and is separated outward through the overflow sleeve 401 and the overflow pipe 402, further improving the separation effect. Sand separation stage: during the operation of the device, the sand particles entering the settling cone 3 gradually settle to the bottom of the feed pipe 201 under the action of gravity, and the separated sand particles are discharged from the discharge pipe 202 of the separation spiral conveyor 1, while the separated water flows out from the drain pipe 12 of the settling cone 3.
