The process of use of the present invention is as follows.
The upper horizontal pipe 41 is connected to the inlet end 71 of the hose 7 at an end 411 outside the chamber 2 through a pipe clamp 412, and a gate valve 73 is provided near the outlet end 72 of the hose 7, and a plurality of floating blocks 74 are fixedly arranged along the lower portion of the hose 7.
The drying pool 8 is prepared to induce the hose 7 to generate a siphon condition. The gate valve 73 and the exhaust valve 441 are opened, water is filled from the water outlet end 72 of the hose 7, air in the hose 7 is exhausted from the exhaust pipe 442, and the water in the hose 7 is blocked in the hose 7 by the check valve 431. After the hose 7 is filled with water, the gate valve 441 and the exhaust valve 442 are closed. As shown in fig. 2, the water outlet end 72 of the hose 7 is placed in the clean water tank 9, the hose 7 in the clean water tank 9 is arranged in a U-shaped 75 mode, the water outlet end 72 of the hose 7 faces upwards, and the highest liquid level of the clean water tank 8 is lower than the bottom of the drying tank. The hose 7 goes around the dike 81, and the water intake head 1 is pulled to the center of the drying chamber 8 on the opposite dike 82 by the pull rope 11.
The positioning process of the water taking head part 1 of the invention is as follows: referring to fig. 2, when the drying tank 8 continuously feeds the raw slurry for a period of time, the hose 7 and the water intake head 1 always float on the liquid level of the raw slurry under the action of the floating block 74 and the floating ring 3. After the raw slurry is stopped feeding for a period of time, supernatant 83 and settled slurry 84 are formed in the drying tank 8. The water taking head 1 is moved to the liquid level with the deepest part of the supernatant 83 pit by using the pull rope 11, and in the process of pulling the hose 7 and the water taking head 1, the hose 7 and the water taking head 1 are always positioned above the supernatant 83 under the action of buoyancy, so that the mud 84 deposited below the supernatant 83 is not disturbed, and the supernatant 83 becomes turbid.
At this time, as shown in fig. 1, the water intake head 1 floats on the surface of the supernatant 83 due to the buoyancy of the float ring 3, the latch 51 is pulled up by the driving string 52 due to the buoyancy of the upper float 53, the elastic string 59 is in a stretched state, the driving string 62 rotates around the rotation shaft 64 due to the buoyancy of the lower float 63, the long rod 69 abuts against the positioning rod 65, and the short rod 68 and the closing plate 61 rotate around the rotation shaft 64 to the upper side of the lower horizontal pipe 42.
The working process of the invention is as follows: as shown in fig. 2, when the gate valve 73 is opened, the water in the hose 7 flows out from the water outlet end 72 of the hose 7 by gravity, a vacuum is formed in the hose 7, the supernatant 83 is pressed into the water inlet end 71 of the hose 7 from the check valve 431 by the atmospheric pressure, and the supernatant flows into the clean water tank 9 from the hose 7, so that a siphon phenomenon is formed inside the hose 7. Under the condition of no external power, the supernatant 83 is discharged to the clean water tank 9, the surface of the sediment slurry 84 is gradually exposed to the air, so that the moisture on the surface of the sediment slurry 84 is evaporated as soon as possible, and the moisture in the sediment slurry 84 is squeezed out to form new supernatant 83. When the bottom of the cavity 2 and the floating ring 3 contacts the surface of the settled slurry 84, the supernatant 83 can only pass through the water-permeable holes 23 to reach the cavity 2. As shown in fig. 3, in the process that the liquid level 22 in the cavity 2 descends, the floating ball 53 descends to the positioning hole 54, the pull of the pull rope 52 is no longer applied to the latch 51, the elastic rope 59 pulls the rod cap 57 back to the raised platform 421, and the through hole 422 is blocked by the soft gasket 58; the lower float 63 descends as the liquid level 22 in the chamber 2 descends, and the transmission rod 62 rotates around the rotation shaft 64 under the action of gravity. As shown in fig. 4, until the closing plate 61 abuts against the water inlet 423 of the lower horizontal pipe 42, the soft cushion layer 66 blocks the water inlet 423, and the water inlet end 71 of the hose 7 does not suck the supernatant 83, thereby preventing the hose 7 from being evacuated. The vacuum is formed in the hose 7, and the hose 7 is arranged in a U-shaped 75 in the clean water tank 9, so that air can be effectively prevented from entering the hose 7 from the water outlet end 72 of the hose 7 to destroy the vacuum state in the hose 7, and the condition that the water in the hose 7 near the water outlet end completely flows out to destroy and induce the hose 7 to generate siphon can be avoided. Otherwise, the preparation for inducing the siphon phenomenon of the hose 7 is carried out outside the drying tank 8, which brings inconvenience to the operation. At this time, the gate valve 72 is closed, and the inside of the hose 7 is still in a vacuum state.
The raw slurry is unevenly precipitated in the drying pool 8, and a plurality of supernatant liquid 83 pits are formed in the drying pool 8. The water intake head 1 is moved to the liquid surface at the deepest position of the other supernatant liquid 83 by using the pull cord 11. Under the buoyancy of the floating ring 3, the water intake head 1 floats on the surface of the supernatant 83. At this time, as shown in fig. 5, under the buoyancy of the upper float ball 53, the bolt 51 is pulled up by the driving rope 52, the elastic rope 52 is in a stretched state, the soft gasket 58 is separated from the raised platform 421, water enters the lower horizontal pipe 42 through the through hole 422, and flows into the hose 7, the vacuum state inside the hose 7 is broken, the pressure difference value received by the sealing plate 61 is reduced, and under the buoyancy of the lower float ball 63, the driving rod 62 rotates around the rotating shaft 64. As shown in fig. 1, until the long rod 69 abuts against the positioning rod 65, the short rod 68 and the closing plate 61 are rotated around the rotating shaft 64 to above the lower horizontal pipe 42, and the inlet end 421 of the lower horizontal pipe 42 is opened. Thus, the above-described working process of the present invention is repeated.
The positioning process of the water taking head part 1 and the working process of the invention are repeated until all supernatant 83 in the supernatant 83 pit in the drying pool 8 is discharged. And (5) waiting for the next time period to continuously feed the original slurry, and discharging the supernatant out of the drying tank again by using the method.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, so: equivalent changes made according to the structure, shape and principle of the invention shall be covered by the protection scope of the invention.
