Description

Technical Field

[0001] The invention relates to the technical field of sludge removal, and in particular to a bottom clearing and silt removal device for aquaculture. Background Art

[0002] At present, after a period of aquaculture, thick silt will form at the bottom of the breeding pond, and the silt contains a large amount of organic matter. If the excessive silt is not cleaned up in time, it is easy to deteriorate the water quality and cause hypoxia or cause fish and shrimp to become sick, thereby affecting the growth of fish, shrimp and other breeding objects in the breeding pond. The existing dredging device generally has a box for holding sludge on the hull, and then uses a sludge pump to pump the silt at the bottom of the breeding pond into the box. However, the silt at the bottom of the breeding pond often contains impurities such as stones and water plants, which makes it impossible for the sludge pump to pump the silt, which may seriously block the pipeline. In addition, since there are breeding objects such as fish fry and shrimp fry in the breeding pond, due to the small size of fish fry and shrimp fry, they are easily pumped away by the sludge pump, causing the death of fish fry and shrimp fry, thereby causing certain losses. Therefore, a bottom cleaning and silt removal device for aquaculture is proposed to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to solve the problem in the prior art that the sludge contains impurities such as stones and aquatic plants, which makes the sludge pump unable to pump the sludge, and the existing dredging device easily pumps out fish fry and shrimp fry in the breeding pond, causing certain losses, and proposes a bottom cleaning and silt removal device for aquaculture.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A bottom clearing and silt removal device for aquaculture comprises a suspension seat, the top end of the suspension seat is fixedly connected to an external box body, the inner side of the external box body is divided into a placement tank and a silt tank by a partition, a silt pump for sucking silt is arranged on the inner side of the placement tank, the suction end of the silt pump is connected to a silt suction assembly through a telescopic hose, a stirring assembly for stirring silt to help drainage is arranged inside the silt tank, a lifting assembly for driving the silt suction assembly to rise and fall is arranged at the bottom end of the suspension seat, and a relatively arranged spiral propeller is installed near the tail of the bottom end of the suspension seat.

[0006] Preferably, the sludge suction assembly includes a sludge hood connected to the telescopic hose, an impurity filter screen fixedly connected to the inner wall of the sludge hood, and a rotating shaft rotatably arranged at the center of the impurity filter screen.

[0007] Preferably, a plurality of impellers are circumferentially distributed at the bottom end of the impeller screen, a combing rod for combing and breaking up the sludge is provided on the surface of the impeller, and a plurality of circumferentially distributed water inlet holes are provided on the side wall of the sludge cover below the impeller.

[0008] Preferably, a communication port is provided inside the suspension seat, and the lifting assembly includes a lifting motor installed on the top of the suspension seat, a lifting shaft rotatably arranged at the bottom of the suspension seat, and a winding wheel relatively arranged on the surface of the lifting shaft.

[0009] Preferably, the output end of the lifting motor is connected to the lifting shaft through a synchronous wheel assembly, and is used to drive the lifting shaft to rotate to provide driving force for the lifting and lowering of the sludge suction assembly. A traction rope is wrapped around the surface of the winding wheel, and one end of the traction rope is fixedly connected to the sludge cover.

[0010] Preferably, a stirring motor is installed on the outer wall of the external box at the sludge tank, the output end of the stirring motor extends into the sludge tank and is fixedly connected to a central axis, and a stirring rod for stirring sludge is fixedly connected to the surface of the central axis.

[0011] Preferably, a drain outlet is provided at the bottom end of the sludge tank and inside the suspension seat, and a filter cloth for filtering sludge is provided inside the drain outlet.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention is provided with a sludge pump and a sludge suction component. The sludge pump is used to pump water in the breeding pond into the inner side of the sludge cover. Under the action of the flow force of the water, the impeller rotates. The impeller rotation can use the combing rod to break up the agglomerated sludge, so that impurities such as stones and water plants in the sludge are separated from the sludge. At the same time, under the action of the impurity filtering mesh plate, the filtering function of impurities such as stones and water plants is realized, ensuring that the sludge pump can only pump away the sludge, ensuring the normal progress of the sludge cleaning operation.

[0014] 2. The present invention is provided with a sludge suction component. When the sludge suction component moves downward, it moves relative to the water, so that the impeller rotates under the impact force of the water, which can drive away the fish fry and shrimp fry. At the same time, when the sludge cover is set at the bottom of the breeding pond, it can play an isolation role to prevent the scattered sludge from spreading and prevent the fish fry and shrimp fry from getting close and being sucked away.

[0015] 3. The present invention can achieve the stirring function of sludge by providing a stirring motor, a stirring rod and a filter cloth, thereby preventing the filter cloth from being blocked by the sludge, and allowing the water pumped up by the sludge pump to be discharged back to the breeding pond through the drain port.

[0025] It should be noted that: when the sludge cover 3 is in contact with the bottom of the breeding pond, the impeller 10 and the water are in a relative motion state. Under the impact of the water, the impeller 10 can rotate. The rotation of the impeller 10 can drive away the fish fry and shrimp fry, and prevent the sludge cover 3 from covering the fish fry and shrimp fry.

[0026] It should be noted that: during the process of pumping water and sludge, the sludge pump 12 rotates the impeller 10 under the action of the flow force of water. The rotation of the impeller 10 can use the combing rod 11 to break up the agglomerated sludge, so that impurities such as stones and water plants in the sludge are separated from the sludge. At the same time, under the action of the impurity filter plate 9, the filtering function of impurities such as stones and water plants is realized, ensuring that the sludge pump 12 can only pump out the sludge, thereby ensuring the normal progress of the sludge cleaning operation.

[0027] The interior of the sludge tank 201 is provided with a stirring assembly for stirring the sludge to assist drainage, and a stirring motor 13 is installed on the outer wall of the external box body 2 located at the sludge tank 201, and the output end of the stirring motor 13 extends to the interior of the sludge tank 201 and is fixedly connected to a central axis, and a stirring rod 14 for stirring the sludge is fixedly connected to the surface of the central axis, and a drainage port is provided at the bottom end of the sludge tank 201 and the interior of the suspension seat 1, and a filter cloth 15 for filtering the sludge is provided on the inner side of the drainage port.

[0029] A lifting assembly for driving the sludge suction assembly to rise and fall is provided at the bottom end of the suspension seat 1. A connecting port is provided inside the suspension seat 1. The lifting assembly includes a lifting motor 5 installed at the top of the suspension seat 1, a lifting shaft 17 rotatably arranged at the bottom end of the suspension seat 1, and a winding wheel 7 relatively arranged on the surface of the lifting shaft 17.

During the downward movement of the silt cover 3, the impeller 10 and the water are in a relative motion state. Under the impact force of the water, the rotation function of the impeller 10 can be realized. The rotation of the impeller 10 can drive away the fish fry and shrimp fry, and prevent the silt cover 3 from covering the fish fry and shrimp fry;

[0035] Then, the sludge cover 3 is placed on the sludge at the bottom of the breeding pond, and then the sludge pump 12 is turned on. The sludge pump 12 pumps the sludge and water into the inner side of the sludge tank 201. Under the action of the flow force of the water, the impeller 10 rotates. The impeller 10 rotates to break up the agglomerated sludge by using the combing rod 11, so that the impurities such as stones and water plants in the sludge are separated from the sludge. At the same time, under the action of the impurity filter screen plate 9, the filtering function of impurities such as stones and water plants is realized, ensuring that the sludge pump 12 can only pump away the sludge, ensuring the normal progress of the sludge cleaning operation;
