[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0017] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a flushing device for the overflow tank of a thickener includes a thickener 1, and also includes an arc plate 2, an arc guide rail 3, a water supply hose 9, a water supply branch pipe 8, a spray head 10, and a motor 6. The arc plate 2 is placed above the overflow tank of the thickener 1. An arc guide rail 3 is arranged along the arc at the top of the arc plate 2. The arc guide rail 3 is a commercially available existing device, composed of a steering vehicle bearing slide and an open-loop track. The steering vehicle bearing slide slides on the open-loop track. A long through hole 4 is arranged along the arc on the arc plate 2. A rack 5 is arranged on the outer wall of the arc plate 2, and the rack 5 is also arc-shaped along the arc plate 2;
[0018] The arc guide rail 3, the arc-shaped long through hole 4, and the rack 5 are all concentric arc-shaped.
[0019] On one side of the carriage bearing slide of the turning vehicle on the arc-shaped guide rail 3, it is fixed to the motor 6. The motor 6 is a stepper motor that can rotate forward and backward. A gear 7 meshing with the rack 5 is fixed on the output shaft of the motor 6. On the other side of the carriage bearing slide of the turning vehicle on the arc-shaped guide rail 3, a water supply branch pipe 8 is fixed. The water supply branch pipe 8 passes through the long through hole 4. The top end of the water supply branch pipe 8 is flange-connected to the water supply hose 9, and the bottom end of the water supply branch pipe 8 is connected to the nozzle 10.
[0020] The motor 6 is engaged with the rack 5 through the gear 7, driving the carriage bearing slide of the turning vehicle on the arc-shaped guide rail 3 to move in an arc, thereby driving the water supply branch pipe 8 to move in the long through hole 4. The water supply hose 9 supplies flushing water to the water supply branch pipe 8, and the flushing water is sprayed into the overflow tank from the nozzle 10 to wash away the deposited salt, which is then washed away along the overflow tank discharge pipe.
[0021] At the bottom of the arc-shaped plate 2, a plug plate 11 is fixed. The plug plate 11 is movably inserted into a slot 12 fixed to the outer wall of the thickener 1. In the present utility model, by movably inserting the plug plate 11 into the slot 12, it meets the installation during use and can be removed during production.
[0022] Multiple slots 12 are fixed to the outer wall of the thickener 1. The present utility model can be installed in multiple slots 12 at different positions, or multiple present utility models can be installed simultaneously to achieve all-round flushing of the overflow tank.
[0023] Working principle: When the present utility model is in use, by movably inserting the plug plate 11 into the slot 12, the water supply hose 9 supplies flushing water to the water supply branch pipe 8, and the flushing water is sprayed into the overflow tank from the nozzle 10 to wash away the deposited salt, which is then washed away along the overflow tank discharge pipe.
[0024] The motor 6 rotates forward or backward and is engaged with the rack 5 through the gear 7, driving the carriage bearing slide of the turning vehicle on the arc-shaped guide rail 3 to move in an arc, thereby driving the water supply branch pipe 8 to reciprocate in the long through hole 4, which can increase the flushing area.
[0025] By arranging a movable nozzle 10 above the overflow tank of the thickener, the present utility model reciprocates and moves in multiple areas to flush the overflow tank, washing away the deposited salt thoroughly, replacing manual labor, reducing labor intensity, saving manpower, and the movable nozzle 10 can be placed at different positions to flush the overflow tank in multiple directions, with thorough flushing.
[0026] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
