a impurity removing component is arranged above the rotating shaft 23 and is used for taking out impurities on the arc-shaped plate 21;
In this embodiment, the transport assembly comprises a transport bin 4; the transport bin 4 is fixedly connected to the high-temperature evaporation bin 2; a piston plate 41 is connected in a sliding way in the transport bin 4; the end face of one side, far away from the high-temperature evaporation bin 2, of the piston plate 41 is fixedly connected with a second electric telescopic rod 42, and the second electric telescopic rod 42 is installed on the bin body 1;
Through holes are formed in the position, close to the high-temperature evaporation bin 2, of one side of the transportation bin 4, which is positioned at the top and the bottom of the transportation bin 4, and check valves are arranged in the through holes, so that percolate and external gas can enter the transportation bin 4 through the check valves;
An air pipe 43 is arranged on the through hole positioned at the top of the transportation bin 4; a conduit 44 is arranged on the through hole at the bottom of the transportation bin 4, and the conduit 44 extends between the rectangular bin 32 and the high-temperature evaporation bin 2;
the inner wall of the high-temperature evaporation bin 2 is provided with uniformly arranged mounting grooves which are positioned in the transportation bin 4; the mounting grooves are internally provided with atomizing nozzles 45, and the atomizing nozzles 45 are inclined downwards;
In this embodiment, the bottom of the high-temperature evaporation bin 2 is fixedly connected with a mounting rack 26; the mounting frame 26 is fixedly connected with a liquid pump 27;
The water inlet pipe of the liquid pump 27 extends to the bottom of the high-temperature evaporation bin 2; the water outlet pipe of the liquid pump 27 is positioned below the pressing plate 3; the water inlet pipe of the liquid pump 27 is made of metal high-temperature resistant material;
Firstly, the pretreated percolate is guided into a space below the pressing plate 3 through the percolate pipe 12, as the high-temperature evaporation bin 2 is partially positioned below the pressing plate 3, part of the percolate can flow out from the inside of the circular bin 32 and fall above the pressing plate 3 at the moment when the liquid level in the circular bin 32 is higher than the height of the circular bin 32, the first electric telescopic rod 31 is controlled to intermittently stretch, the pressing plate 3 can be driven to move downwards in the shrinking process of the first electric telescopic rod 31, the distance of the downward movement of the pressing plate 3 cannot exceed the position of the bottom of the high-temperature evaporation bin 2, the downward movement of the pressing plate 3 can squeeze the percolate below the pressing plate 3, the percolate can enter the circular bin 32 through the one-way valve in the first liquid inlet 33, and when the liquid level in the circular bin 32 is higher than the height of the circular bin 32, part of the percolate can flow out from the inside of the circular bin 32 and fall above the pressing plate 3, and can be driven to move upwards when the first electric telescopic rod 31 is restored to the initial state, and the percolate can flow to the position below the pressing plate 3 through the one-way valve 34 when the height of the pressing plate 3 is higher than the liquid level below the pressing plate 3; the percolate entering the circular bin 32 increases the contact area with the high-temperature evaporation bin 2, so that the percolate in the circular bin 32 can be further preheated, and then the percolate in the circular bin 32 is transmitted through the transmission assembly;
Specifically, when the transmission assembly works, the second electric telescopic rod 42 is controlled to continuously extend and retract, and in the process of retracting the second electric telescopic rod 42, the piston plate 41 in the conveying bin 4 is driven to be far away from the through hole, so that the preheated percolate in the loop-shaped bin 32 can be pumped into the conveying bin 4 through the guide pipe 44, and the gas in the bin body 1 can be pumped into the conveying bin 4 through the gas pipe 43;
In the process of extending the second electric telescopic rod 42, the piston plate 41 is driven to push the percolate and gas in the transport bin 4, and as the check valve is arranged in the through hole, the percolate and the gas in the transport bin 4 are prevented from being discharged through the through hole, so that the percolate and the gas can enter the atomizing nozzle 45 in the installation groove, and then the percolate and the gas can be sprayed out through the atomizing nozzle 45, and as the gas and the percolate are sprayed out through the atomizing nozzle 45 together, the gas can push the percolate to be sprayed out, so that the atomization effect of the sprayed percolate can be improved, when the percolate is sprayed out from the atomizing nozzle 45, the percolate can fall on the arc plate 21, and as the arc plate 21 is positioned in the high-temperature evaporation bin 2, the atomized percolate can be evaporated under the action of high temperature, and meanwhile, if part of the percolate falling on the arc plate 21 is not evaporated, the part of the percolate can flow on the arc plate 21, so that the part of the percolate can be fully contacted with the arc plate 21, the part of the percolate can be evaporated, the arc plate 22 can block the percolate on the arc plate 21, and prevent the percolate from flowing down from two sides of the percolate, when the percolate is evaporated, and after the vapor is discharged through the air outlet pipe 11, the vapor can be discharged, and then processed, and the vapor can be discharged;
More specifically, after the percolate falling on the arc plate 21 is evaporated, impurities and other substances carried in the percolate are adhered to the arc plate 21, and when the second electric telescopic rod 42 drives the piston plate 41 to suck the percolate and the gas again, the first motor 24 drives the rotating shaft 23 to rotate for a circle, meanwhile, the rotating shaft 23 drives the arc plate 21 to rotate through the driving plate 25, the rotating arc plate 21 passes through the impurity removing assembly, the impurity removing assembly can remove the adhered impurities on the arc plate 21, the heat conducting effect of the arc plate 21 is prevented from being influenced along with the accumulation of the impurities, and therefore the evaporation effect of the percolate is reduced;
Further, if the percolate falling onto the arc plate 21 cannot be completely evaporated, when the rotating shaft 23 drives the arc plate 21 to rotate, the residual percolate on the arc plate 21 can fall into the bottom of the high-temperature evaporation bin 2, and the percolate falling into the bottom of the high-temperature evaporation bin 2 can be pumped into the lower part of the pressing plate 3 by the liquid pump 27 again, so that the percolate is prevented from remaining on the arc plate 21 all the time, and the evaporation process of the arc plate 21 on the newly sprayed percolate is prevented from being influenced;
therefore, the high-temperature evaporation bin 2 is used for preheating the percolate, and then the preheated percolate is communicated with gas and sprayed onto the arc-shaped plate 21 through the atomizing nozzle 45, so that the atomization effect of the percolate can be improved in the process, the evaporation speed of the percolate can be accelerated, impurities attached to the arc-shaped plate 21 can be removed by utilizing the impurity removing assembly, the heat conduction effect of the arc-shaped plate 21 can be influenced along with the accumulation of the impurities on the arc-shaped plate 21, and the evaporation effect of the percolate is reduced.
Embodiment two:
Referring to fig. 3-8, unlike the first embodiment, the impurity removing unit includes an impurity removing tube 5; the impurity removing pipe 5 is positioned above the rotating shaft 23; the length of the impurity removing pipe 5 is the same as the distance between the two arc baffles 22; a chute 51 is arranged at the top of the impurity removing pipe 5; the impurity removing pipe 5 is internally tangent with the rotated arc-shaped plate 21;
an extension pipe 52 is fixedly connected to one side of the impurity removal pipe 5 facing the first motor 24, and the diameter of the inner ring of the extension pipe 52 is the same as that of the inner ring of the impurity removal pipe 5; the other side of the extension pipe 52 extends to the outer side of the bin body 1; the surface of the bin body 1 is fixedly connected with a collecting bin 53, and the extension pipe 52 extends into the collecting bin 53;
The collection bin 53 is fixedly connected with a second motor 54; a driving shaft of the second motor 54 is fixedly connected with a packing auger 55 through a coupling, and the packing auger 55 extends to the end part of the impurity removing pipe 5;
In this embodiment, the outer ring diameter of the extension pipe 52 is smaller than the outer ring diameter of the impurity removal pipe 5; the extension pipe 52 is internally tangent with the rotated arc baffle 22;
in the rotating process of the arc plate 21, as the inner ring of the arc plate 21 is internally tangent with the impurity removing pipe 5, when the arc plate 21 rotates to the position of the impurity removing pipe 5, the chute 51 on the impurity removing pipe 5 can scratch the inner surface of the arc plate 21, so that impurities adhered on the arc plate 21 can be scraped into the chute 51 and then fall into the impurity removing pipe 5, and meanwhile, the second motor 54 is controlled to rotate, so that the auger 55 is driven to rotate, and the rotating auger 55 can gradually bring out the impurities in the impurity removing pipe 5 and finally fall into the collecting bin 53;
Specifically, since the extension pipe 52 is inscribed with the rotated baffle plate 22, when the baffle plate 22 rotates following the arc plate 21, the baffle plate 22 can rotate along the extension pipe 52, so that the baffle plate 22 cannot collide with the extension pipe 52;
more specifically, because the second electric telescopic rod 42 drives the piston plate 41 to suck the percolate and the gas again, the first motor 24 drives the arc plate 21 to rotate for a circle, so that the arc plate 21 can be cleaned in the process that the atomizing nozzle 45 does not spray water, and therefore, the arc plate 21 is in a state of being not adhered with impurities when the atomizing nozzle 45 sprays water each time, the evaporation effect of the percolate can be improved, impurities on the arc plate 21 are prevented, the evaporation effect of the percolate can be reduced, and compared with the existing evaporation equipment, cleaning of the adhered impurities in the evaporation device is not needed at intervals, so that labor cost is saved.
