Sludge is pumped from the lagoon as a slurry. Because the area of the oxidation pond is very large, in order to improve the dredging efficiency, the power of the related pump is also large, so that the speed of heavy objects such as stones in the sludge in the pipeline is high, and thus, the pump body is easy to damage. After the sludge enters the dredging shell 401, under the action of the three baffles, the motion track of the sludge is snakelike, and heavy objects such as stones and the like directly impact the baffles, so that the speed of the sludge is reduced. In this way, the weight is more likely to settle until it falls to the bottom of the settling tank 405. Meanwhile, light and flexible garbage in the sludge, such as ropes and the like, can be blocked by the intercepting rods and even wound on the intercepting rods, so that the components of the sludge are more single.

Further, the bottom of desilting casing 401 is equipped with two through-holes, and the through-hole of the bottom of desilting casing 401 communicates with the upper end opening of subsider 405, subsider 405 is the toper, and the bottom of subsider 405 is equipped with the bin outlet, is equipped with the relief valve on the bin outlet to discharge the heavy object that will subside in the subsider 405 bottom.

Because the oxidation pond is arranged in the open air, under the action of sunlight and wind power, sludge on the surface of the oxidation pond is easy to dry and harden and even agglomerate, thereby bringing difficulty to pollution discharge. In order to prevent this, referring to fig. 5, the cattle oxidation pond dredging and conveying device 10 further comprises a universal stirring nozzle 80 for stirring the solid sludge into fluid, wherein a plurality of injection ports 801 are arranged on the universal stirring nozzle 80, and the injection ports 801 are radially distributed on the nozzle. When the universal stirring nozzle is used, please refer to fig. 6, the universal stirring nozzle 80 is connected with the rotor pump 602 through a pipeline, meanwhile, the other end of the rotor pump 602 is also introduced into the upper part of the oxidation pond through a pipeline, sludge on the upper part of the oxidation pond is pumped into the pump by the rotor pump 602, the rotor pump 602 discharges the sludge through the universal stirring nozzle 80, clear water or sludge with lower viscosity on the upper part of the oxidation pond is used for stirring sludge with higher viscosity on the lower part, the viscosity of the sludge is reduced, and the subsequent dredging operation is conveniently and smoothly carried out. Meanwhile, the universal stirring nozzle 80 can enlarge the sludge spraying length in the dredging and conveying of the oxidation pond, and is convenient to discharge to farmlands uniformly.

Further, the cattle oxidation pond dredging and conveying device 10 further comprises a buoy 90, so that the first filtering device 20 can float on the surface layer of the sludge. Thus, the pressure of the first filter device 20 against the bottom of the pond is greatly reduced. When the anti-seepage film is laid at the bottom of the pond, the anti-seepage film can be effectively prevented from being scraped due to the blunt design of the first filtering device 20.

In a preferred embodiment, the pontoons 90 are positioned on opposite sides of the first filter apparatus 20 to equalize the forces on the opposite sides of the first filter apparatus 20.

In another preferred embodiment, the float 90 is fixed to the first drain pipe 30. The buoy 90 includes an outer hull and a less dense float such as an air bladder, plastic foam, or the like.
