Detailed Description

Example 1

As shown in fig. 1, the present embodiment provides a silt deposit tank, which includes a first tank body 1, a second tank body 2, a third tank body 3 and a clean water tank 4, wherein a water inlet pipe 5 is arranged on one side of the first tank body 1 away from the second tank body 2; the bottom of the first tank body 1, the second tank body 2 and the third tank body 3 is obliquely arranged, the side wall of the lower end of the first tank body 1, the second tank body 2 and the third tank body 3 is provided with a silt outlet, and the side walls of the first tank body 1, the second tank body 2 and the third tank body 3 corresponding to the silt outlet are provided with a mud guard 6 through fastening bolts 11; a channel 7 is respectively arranged between the first tank body 1 and the second tank body 2, between the second tank body 2 and the third tank body 3, and between the third tank body 3 and the clean water tank 4, a plurality of baffle plates 8 are arranged between two opposite side walls of the first tank body 1, the second tank body 2 and the third tank body 3, the baffle plates 8 are sequentially arranged along the direction from the first tank body 1 to the clean water tank 4, and the heights of the baffle plates 8 are sequentially reduced along the direction; the two opposite side walls of the first tank body 1, the second tank body 2 and the third tank body 3 are respectively provided with a partition plate 9, and the partition plates 9 and the flow baffle plate 8 are arranged in parallel and are close to the channel 7; a filter assembly 10 is arranged between the partition plate 9 and the side wall of the channel 7, and the filter assembly 10 is positioned below the channel 7; the filter assembly 10 comprises an upper layer of filter screen and a lower layer of filter screen and filter stones clamped between the two layers of filter screens; and overflow pipes are respectively arranged on the side walls of the first tank body 1, the second tank body 2 and the third tank body 3.

The working principle is as follows:

muddy water with silt enters through the water inlet pipe 5 of the first tank body 1 and is subjected to primary sedimentation of silt in the first tank body 1, and after the water level of the first tank body 1 reaches the passage 7 between the muddy water and the second tank body 2, the clear water on the upper layer enters the second tank body 2 through the passage 7 after being filtered by the filtering component 10. Similarly, the turbid water undergoes secondary sedimentation and tertiary sedimentation in the second tank body 2 and the third tank body 3, and finally enters the clean water tank 4 through the passage 7 after being filtered by the filter assembly 10.

The flow baffle plates 8 arranged on the inner walls of the first tank body 1, the second tank body 2 and the third tank body 3 can reduce the flowing speed of the turbid water when entering the tank bodies, and meanwhile, the heights of the flow baffle plates 8 are reduced in sequence, so that the sedimentation of silt is facilitated, and the treatment efficiency of the turbid water is improved.

When the sediment deposited in the first tank body 1, the second tank body 2 and the third tank body 3 reaches a certain amount, the mud guard 6 is detached to discharge the deposited sediment to the sediment collecting device through the sediment outlet. And the first tank body 1, the second tank body 2 and the third tank body 3 are obliquely arranged at the bottoms, so that the discharge of silt is accelerated, and the treatment efficiency of turbid water is improved.

When the sediment deposited in the first tank body 1, the second tank body 2 and the third tank body 3 is too much and is not discharged in time, the water level in the first tank body 1, the second tank body 2 and the third tank body 3 is too high, and finally the surplus water flows out of the overflow pipe to the buffer tank or the container for storing the turbid water.

Example 2

As shown in fig. 2, on the basis of embodiment 1, the mudguard 6 is provided with a plurality of limiting protrusions 12, and the side walls of the first tank body 1, the second tank body 2 and the third tank body 3 are provided with limiting grooves corresponding to the positions of the limiting protrusions 12. When the mudguard 6 is installed, the limit bulge 12 of the mudguard 6 can be inserted into the limit groove, so that the installation position of the mudguard 6 can be quickly positioned, the installation is convenient, and the working efficiency is improved.
