[0001] The utility model relates to the technical field of deep cone thickeners, in particular to an accident pool for deep cone thickeners. Background Art
[0002] The volume of the deep cone thickener is very large, often reaching thousands of cubic meters. Once an accident occurs, thousands of cubic meters of material are difficult to handle, and a large amount of water is required to clean the material in the thickener. There is also nowhere to store the material cleaned out during this period.
[0003] The most common method at present is to set up an accident pool. However, due to the limitation of the site, it is impossible to build a large enough accident pool, and it is not economically reasonable to build an accident pool of several thousand cubic meters. Once an accident occurs, the scene will be very chaotic.
[0004] In view of this, the present utility model is proposed. Utility Model Content

[0016] Preferably, an overflow trough is provided at the upper edge of the sedimentation tank, and the overflow trough is connected to the pump pit.
[0017] Preferably, the pump pit is also connected to a deep cone thickener, and overflow water in the pump pit is pumped back into the deep cone thickener through a sewage pump.
[0018] Compared with the prior art, the accident pool for a deep cone thickener proposed by the utility model has the following advantages:
[0019] 1. In an accident pool for a deep cone thickener proposed by the utility model, a first sedimentation tank and a second sedimentation tank are arranged, so that one can work normally and the other can be cleaned, thus improving the accident cleaning efficiency of the deep cone thickener.
[0020] 2.

[0022] 4. In an accident pool for a deep cone thickener proposed by the utility model, the first sedimentation tank and the second sedimentation tank have a slope of 5% from the side of the feed barrel to the side of the pump pit, so that when the accident of the deep cone thickener is cleaned up, the sludge in the first sedimentation tank and the second sedimentation tank will flow along the slope to the pump pit side at the bottom of the slope, so that the sludge in the first sedimentation tank and the second sedimentation tank can be easily cleaned; at the same time, in order to further facilitate the cleaning of the sludge in the first sedimentation tank and the second sedimentation tank, a cleaning pump pit is provided at the bottom of the slope, so that all the sludge enters the cleaning pump pit along the slope, so that only the sludge in the cleaning pump pit needs to be cleaned up at the end.

[0033] The utility model proposes an accident pool for a deep cone thickener 100. By setting a first sedimentation tank 200 and a second sedimentation tank 300, one can work normally while the other can be cleaned. In this way, the accident pool with a small footprint can be used to handle accidents occurring in large-volume and large-capacity equipment and facilities such as the deep cone thickener 100, thereby improving the accident cleaning efficiency of the deep cone thickener 100.
[0034] In the above embodiment, the underflow pipe of the deep cone thickener 100 enters the feeding barrel 400 tangentially along the cylinder of the feeding barrel 400. Two dosing ports are arranged above the feeding barrel 400, and the flocculant dosing device 500 injects flocculant from the dosing ports through a pipe.
[0035] Before entering the accident pool, the slurry of the utility model first enters the feed barrel 400 to mix with the flocculant, so that the mineral particles in the slurry can be quickly settled in the first sedimentation tank 200 and the second sedimentation tank 300, thereby improving the accident cleaning efficiency of the deep cone thickener 100. At the same time, the underflow pipe of the deep cone thickener 100 enters the feed barrel 400 along the tangent of the cylinder of the feed barrel 400, so that the slurry in the deep cone thickener 100 will form a rotating vortex in the feed barrel 400 after entering the feed barrel 400 along the tangent. In the vortex environment, the slurry can be better mixed with the flocculant sent into the feed barrel 400.
[0036] In the above embodiment, the first sedimentation tank 200 and the second sedimentation tank 300 have a slope of 5% from the side of the feed barrel 400 to the side of the pump pit 600. The first sedimentation tank 200 and the second sedimentation tank 300 are provided with a cleaning pump pit 210 on the side of the pump pit 600.

The pump pit 600 is also connected to the deep cone thickener 100, and the overflow water in the pump pit 600 is pumped back to the deep cone thickener 100 through the sewage pump 610.
[0040] In the accident pool for a deep cone thickener 100 proposed by the utility model, overflow water in the pump pit 600 can flow back into the deep cone thickener 100 for continued use to clean the deep cone thickener 100. Although the overflow water obtained in this way is not clear, it will not have any impact on the cleaning of the deep cone thickener 100 and can also save water resources.
