Description

Technical Field

[0001] The utility model relates to the technical field of mud treatment, in particular to a sand making mud-water separation device. Background Art

[0002] Mining enterprises are located in ecologically sensitive areas. During the production process, a large amount of muddy and water waste is generated, which contains a large amount of heavy metals and harmful chemicals. If it is directly discharged into the environment without control, it will seriously pollute the surrounding environment. Mud and water separation, as a key link in sewage treatment, plays an important role in water resources and environmental protection.

[0003] In the related art, commonly used mud and water separation equipment, such as high-efficiency cyclones, vibrating screens, etc., perform preliminary separation on the mud and water, and then discharge the mud and water into a sedimentation tank to treat heavy metals and harmful chemicals. Flocculants are added to the sedimentation tank to accelerate the precipitation of harmful substances. Since the mud and water are directly discharged into the sedimentation tank, the mud fluidity of the mud and water is poor. When flocculants are added for precipitation, this leads to a decrease in the efficiency of the sedimentation treatment, or it is necessary to prepare multiple sedimentation tanks for multiple treatments, which prolongs the treatment process and also leads to an increase in treatment energy consumption. In addition, the treatment efficiency and environmental protection still need to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a sand making mud water separation device to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a sand making mud water separation device, comprising a plurality of cyclones, a mud inlet pipe is installed at the lower end of the cyclone, a maintenance cover is connected to the surface of the mud inlet pipe, and a mud box is provided on the lower surface of the maintenance cover;

[0006] The cyclone can separate part of the water in the mud and water, reduce the water content of the mud entering the mud box, and reduce the size of the lower part of the mud box, which is conducive to the sludge sinking to the lower part of the mud box and convenient for the screw conveyor to discharge the sludge;

[0007] A connecting strip is provided on the lower surface of the inspection cover, a cone cap is provided at the lower end of the connecting strip, a diffusion cone is provided on the upper surface of the cone cap, and the diffusion cone is located below the mud inlet pipe. The mud discharged from the mud inlet pipe is dispersed to the cone cap by the diffusion cone. The cone cap diffuses the mud in a ring shape, which can be more fully contacted with the magnetic flocculant, thereby improving the flocculation efficiency.

[0008] A motor is installed on the side of the mud box, and the output shaft of the motor is inserted into the mud box and connected to a driving frame, the driving frame is fixedly connected to a bracket, a stirring ring is sleeved on the bracket, and the stirring ring is inclined. The stirring ring will swing during the rotation process, which can speed up the flow of mud water and magnetic flocculant and make the sedimentation faster;

[0009] A screw conveyor is installed at the lower right side of the mud box, and the right end of the screw conveyor is inclined upward. A mud discharge pipe is installed on the surface of the screw conveyor. The screw conveyor discharges the mud from the mud box. The inclined screw conveyor can allow water to flow into the mud box when discharging mud, thereby reducing the water content in the mud.

[0010] Furthermore, a water outlet weir plate is installed inside the mud box, an overflow pipe is installed on the surface of the mud box, and the overflow pipe corresponds to the position of the water outlet weir plate. The water outlet weir plate can prevent mud from being discharged from the overflow pipe along with water, thereby reducing the mud content in the water.

[0011] Furthermore, a drain outlet is provided at the lower left side of the mud box, and the drain outlet is connected to a valve. When the mud box needs to be cleaned, clean water can be discharged through the drain outlet, and some impurities can also be discharged from the drain outlet. The drain outlet is sealed by the valve to prevent mud and water leakage.

[0012] Furthermore, the surface of the inspection cover is connected with a plurality of adding pipes, the lower ends of the adding pipes are connected with diverter heads, and the magnetic flocculant is added to the mud box through the adding pipes. The diverter head can diffuse the magnetic flocculant into the mud box, and the sedimentation speed of the mud can be accelerated.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) After the mud and water are separated by the cyclone, the mud is discharged into the mud box through the mud inlet pipe. The magnetic flocculant is added to the mud box using the adding pipe. The motor drives the bracket, stirring ring and driving frame to rotate. The inclined stirring ring swings greatly during rotation, which allows the magnetic flocculant to fully and quickly contact the mud, and can quickly and effectively coagulate the mud, with high flocculation efficiency for pollutant removal.

[0015] (2) A plurality of dividing strips on the cone cap form multiple flow channels on the cone cap, and the mud diffuses into the mud box in an umbrella shape along the flow channels, thereby increasing the contact area between the mud and the magnetic flocculant, achieving a rapid mud-water separation effect, and accelerating the mud-water treatment process.

When the stirring ring 21 rotates, the mud and the magnetic flocculant in the mud box 1 can be stirred more greatly, and the mud coagulation can be achieved quickly;

[0028] A screw conveyor 12 is installed at the lower right side of the mud box 1, and the right end of the screw conveyor 12 is inclined upward. During the mud discharge process, water flows downward along the screw conveyor 12 and the mud is discharged upward. A mud discharge pipe 13 is installed on the surface of the screw conveyor 12 to discharge mud with low water content from the mud discharge pipe 13.
