Abstract
Description
Technical field:
[0001] The utility model relates to the technical field of gold mine production equipment, in particular to an improved thickener descaling device. Background technology:
[0002] The working principle of the thickener is mainly based on solid-liquid separation, that is, using the principles of gravity, buoyancy and sedimentation to make the solid particles in the slurry settle to the bottom of the pool, thereby achieving concentration and dehydration treatment, and the supernatant enters the overflow weir through the overflow hole and is discharged through the discharge pipe on the overflow weir. Due to the presence of flocculants, there is a small amount of slurry foam and impurities on the surface of the supernatant. For this reason, a filter box is usually installed at the discharge pipe position for impurity filtering. In order to prevent the filter box from being blocked, the filter box needs to be taken out regularly for dirt cleaning. However, the diameter of the thickener is usually more than 50 meters. It is very dangerous to clean the filter box on the overflow weir. Workers are prone to fall into the thickener and serious safety accidents occur. For this reason, a wire cage is usually constructed at the filter box position for protection. It can be seen that the filter box operation is not only time-consuming and labor-intensive, affecting normal production, but also dangerous. It is also necessary to configure protective cages and other equipment. The operation is cumbersome and the equipment cost is high. It is urgent to design an automatic descaling device to clean the filter box. Utility model content:

[0012] Figure 2 It is a three-dimensional diagram of the filter box of the utility model;
[0013] Figure 3 This is the control block diagram of the utility model;
[0014] In the figure, there are a thickening body 1, an overflow weir 2, a drain pipe 3, a filter box 4, a filter plate 6, a connecting beam 7, a cylinder 8, a compressed air pipeline 9, a proximity switch 10, a PLC controller 11, a solenoid valve 12, a gantry 13, a dirt receiving plate 14, a dirt baffle plate 15, and a drain hole 16. Specific implementation method:
[0015] like Figure 1 and Figure 2 As shown, an improved thickener descaling device is applied to a thickener body 1, an overflow weir 2 is installed on the outer edge of the thickener body 1, a drain pipe 3 is installed on the overflow weir 2, a filter box 4 with a top opening is arranged in the overflow weir 2, a cylinder 8 is arranged above the filter box 4, a piston rod of the cylinder 8 is connected to the filter box 4, the cylinder 8 is installed on a gantry 13, the gantry 13 is installed on the overflow weir 2, and a compression cylinder 8 is installed on the top plate of the gantry 13. An air pipeline 9 is provided, on which a solenoid valve 12 is installed. When the piston rod of the cylinder 8 is in a retracted state, the top plate of the gantry 13 seals the filter box 4. Filter plates 6 are provided on both sides of the filter box 4. A drainage hole 16 matching the position of the drainage pipe 3 is provided on the filter box 4. A connecting beam 7 is connected to the top of the filter box 4, and the connecting beam 7 is connected to the piston rod of the cylinder 8. A sealing gasket is installed on the top plate of the gantry 13.
[0016] like Figure 3 As shown, a proximity switch 10 is installed on the top plate of the gantry 13 , and the proximity switch 10 is used to detect the position of the filter box 4 . The proximity switch 10 is electrically connected to a PLC controller 11 , and the PLC controller 11 is electrically connected to the solenoid valve 12 .
[0017] In order to better collect the dirt on the filter box 4 and prevent the dirt from splashing randomly during the purge, Figure 1 As shown, a dirt receiving plate 14 is provided at both sides of the gantry 13 , and the dirt receiving plate 14 is fixedly mounted on the overflow weir 2 ; a dirt baffle plate 15 is mounted on the dirt receiving plate 14 .
[0018] When doing specific work, such as Figures 1 to 3 As shown, the cylinder 8 can be started once per shift. After starting the cylinder 8, the filter box 4 rises, and the top of the filter box 4 is sealed by the top of the gantry 13 (at this time, the drainage hole 16 is still blocked and sealed by the inner wall of the overflow weir), so that a relatively closed space is formed inside the filter box 4. At this time, the proximity switch 10 detects the position information of the filter box 4 and sends an electrical signal to the PLC controller 11. The PLC controller 11 controls the solenoid valve 12 to open, so that the compressed air pipeline 9 blows out compressed air, thereby blowing out the dirt on the filter plate 6, and completing the cleaning of the filter box 4.
