Description

Technical Field

[0001] The utility model relates to the technical field of tailings transportation, in particular to a tailings mortar transportation pipeline structure. Background Art

[0002] Tailings refers to the waste discharged by the ore dressing plant after grinding the ore and selecting the useful components under specific economic and technical conditions. The tailings slurry discharged by the ore dressing plant is generally formed by natural dehydration. It is the main component of solid industrial waste and can be regarded as a composite mineral material such as silicate\carbonate.

[0003] At present, after being processed, tailings are formed into mortar with a viscosity of 70%, which is transported to the conveying pipeline through the discharge pipe at the bottom of the tailings bin, and then transported to the next process through the conveying pipeline. The conveying pipeline and the discharge pipe are generally arranged vertically. The mortar is extremely easy to accumulate during the transportation process, especially at the corners of the discharge pipe and the conveying pipeline, where mortar accumulation is more likely to occur. The long-term accumulation of mortar causes the blockage of the conveying pipeline. As the blockage time of the mortar is too long, the mortar in the ore bin is also caused to accumulate for a long time, affecting the subsequent storage of mortar in the ore bin, thereby affecting the normal process. Utility Model Content

[0004] The utility model aims at the deficiencies in the prior art and provides a tailings mortar conveying pipeline structure.

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A tailings mortar conveying pipeline structure comprises a sand bin for storing mortar, the discharge port of the sand bin is connected to a discharge pipe, a conveying pipe is fixedly provided at one end of the discharge pipe away from the discharge port, and the conveying pipe is perpendicular to the discharge pipe, the outer wall of the conveying pipe is connected to a backwashing pipe, and a ball valve is provided on the backwashing pipe, the backwashing pipe is inclined, and the discharge end of the backwashing pipe faces the connection between the discharge pipe and the conveying pipe, and the backwashing pipe is used for adding high-pressure water.

[0007] By adopting the above technical solution, high-pressure water is added to the backwash pipe. Since the discharge end of the backwash pipe is toward the corner of the discharge pipe and the conveying pipe, the high-pressure water can be flushed toward the corner of the discharge pipe and the conveying pipe (backward flushing). The mortar accumulated in the conveying pipe and at the corner of the conveying pipe and the discharge pipe can be flushed away by the high-pressure water, so that the mortar can be transported more conveniently. This method can reduce the viscosity of the mortar to 65%, reduce the possibility of mortar accumulation, and ensure the normal progress of the process; at the same time, the backwash pipe can be used as a sampling point. When high-pressure water is not passed into the backwash pipe, the ball valve is opened, and the mortar in the conveying pipe can be taken out through the backwash pipe to measure the concentration of the mortar, thereby avoiding inaccurate sampling and measurement of the mortar concentration in the subsequent process (mixing tank), thereby improving the accuracy of the measurement.

[0008] Furthermore, the angle between the backwash pipe and the delivery pipe is 30°-50°.

[0009] Furthermore, the angle between the backwash pipe and the delivery pipe is 45°.

[0010] By adopting the above technical solution, the mortar is extremely easy to accumulate during the transition from the discharge pipe to the delivery pipe. There is an angle between the backwash pipe and the delivery pipe, so that the backwash pipe is tilted towards the corner of the delivery pipe and the discharge pipe. The possibility of mortar accumulation is reduced through reverse flushing of high-pressure water.

[0011] Furthermore, a stirring paddle is rotatably connected at the corner of the conveying pipe and the discharge pipe, and a motor for driving the stirring paddle to rotate is connected to the outer wall of the discharge pipe through a support frame, and the output shaft of the motor is coaxially and fixedly connected to the stirring paddle.

[0012] By adopting the above technical solution, the stirring paddle is driven to rotate by a motor, and the stirring paddle can stir the mortar in the pipeline during the rotation process, further disperse the mortar, and prevent the mortar from accumulating.

[0013] Furthermore, a protrusion is provided at the end of the stirring paddle, a groove is provided at the end of the output shaft of the motor, the protrusion is adapted to the groove, and the protrusion is located in the groove, and the protrusion is connected to the output shaft of the motor by bolts and nuts.

[0014] By adopting the above technical solution, the protrusion and the output shaft of the motor are connected by bolts and nuts, which can ensure the concentricity and coaxiality between the stirring paddle and the output shaft of the motor, and improve the stability of the stirring paddle during rotation. At the same time, when the stirring paddle is damaged and needs to be replaced or repaired, the bolts and nuts can be removed to take out the stirring paddle, so that the stirring paddle can be replaced or repaired separately, which improves the convenience of replacement and saves costs.

[0020] The utility model embodiment discloses a tailings slurry conveying pipeline structure.

[0021] Reference Figure 1-Figure 3 A tailings mortar conveying pipeline structure comprises a sand bin 1 for storing mortar, a discharge port is provided at the bottom end of the sand bin 1, a discharge port of the sand bin 1 is connected to a discharge pipe 2, the discharge pipe 2 is vertically arranged, a conveying pipe 3 is fixedly arranged at one end of the discharge pipe 2 away from the discharge port, the conveying pipe 3 is perpendicular to the discharge pipe 2, the conveying pipe 3 is horizontally arranged, and the corners of the conveying pipe 3 and the discharge pipe 2 are chamfered, so that the mortar is conveyed more smoothly; the outer wall of the conveying pipe 3 is connected to a backwashing pipe 4, and a ball valve (not shown in the figure) is provided on the backwashing pipe 4, and the opening or closing of the backwashing pipe 4 can be controlled by opening or closing the ball valve; the backwashing pipe 4 is used to be connected to a high-pressure water gun for passing into the backwashing pipe 4; the backwashing pipe 4 is inclined, and the discharge end of the backwashing pipe 4 faces the connection between the discharge pipe 2 and the conveying pipe 3.

[0022] High-pressure water is added to the backwash pipe 4. Since the discharge end of the backwash pipe 4 faces the corner of the discharge pipe 2 and the conveying pipe 3, the high-pressure water can be used to wash the corner of the discharge pipe 2 and the conveying pipe 3 (backwash). The mortar accumulated in the conveying pipe 3 and at the corner of the conveying pipe 3 and the discharge pipe 2 can be washed away by the high-pressure water, so that the mortar can be transported more conveniently. This method can reduce the viscosity of the mortar to 65%, thereby reducing the possibility of mortar accumulation and ensuring the normal progress of the process. At the same time, the backwash pipe 4 can be used as a sampling point. When high-pressure water is not passed into the backwash pipe 4, the ball valve is opened, and the mortar in the conveying pipe 3 can be taken out through the backwash pipe 4 to measure the concentration of the mortar, thereby avoiding inaccurate sampling and measurement of the mortar concentration in the subsequent process (mixing tank), thereby improving the accuracy of the measurement.

[0023] The angle between the backwash pipe 4 and the delivery pipe 3 is 30°-50°. In this embodiment, the angle between the backwash pipe 4 and the delivery pipe 3 is 45°. During the transition of the mortar from the discharge pipe 2 to the delivery pipe 3, the mortar is extremely easy to accumulate. There is an angle between the backwash pipe 4 and the delivery pipe 3, so that the backwash pipe 4 is tilted toward the corner of the delivery pipe 3 and the discharge pipe 2. The possibility of mortar accumulation is reduced through the reverse flushing of high-pressure water.

[0024] A stirring paddle 5 is rotatably connected to the corner of the conveying pipe 3 and the discharging pipe 2. The stirring paddle 5 includes a stirring shaft 6 and a stirring blade 7. The stirring blade 7 is fixed to the end of the stirring shaft 6, and the stirring blade 7 is in an "∞" shape, such as Figure 1 and Figure 3 As shown; the stirring paddle 5 is tilted and is located at the position where the discharge pipe 2 and the conveying pipe 3 are connected. The mortar can be stirred by rotating the stirring paddle 5 to achieve the purpose of breaking up the mortar. The outer wall of the discharge pipe 2 is connected to a motor 8 for driving the stirring paddle 5 to rotate through a support frame 9. The purpose of the support frame 9 is to fix the position of the motor 8, support and fix the motor 8. The output shaft of the motor 8 is coaxially fixedly connected to the stirring paddle 5. The stirring paddle 5 is driven to rotate by the motor 8. The stirring paddle 5 can stir the mortar in the pipeline during rotation, further break up the mortar, and prevent mortar accumulation.

[0025] The end of the stirring shaft 6 away from the stirring blade 7 is fixedly connected with a protrusion 13, and the diameter of the protrusion 13 is smaller than the diameter of the stirring shaft 6. Figure 2 and Figure 3 As shown, a groove 14 is formed at the end of the output shaft of the motor 8 , the protrusion 13 is matched with the groove 14 , and the protrusion 13 is located in the groove 14 , and the protrusion 13 is connected to the output shaft of the motor 8 by means of a bolt 10 and a nut 11 .

[0026] Reference Figure 1-Figure 3The protrusion 13 is connected to the output shaft of the motor 8 by means of the bolt 10 and the nut 11, which can ensure the concentricity and coaxiality between the stirring paddle 5 and the output shaft of the motor 8, thereby improving the stability of the stirring paddle 5 during rotation. At the same time, when the stirring paddle 5 is damaged and needs to be replaced or repaired, the bolt 10 and the nut 11 can be removed, and the stirring paddle 5 can be taken out, so that the stirring paddle 5 can be replaced or repaired separately, thereby improving the convenience during replacement and saving costs.
