Description

Technical Field

[0001] This invention relates to the field of aquaculture pond drainage technology, and in particular to an aquaculture pond impurity removal device. Background Technology

[0002] my country is a major aquaculture country, with its annual aquaculture output ranking first in the world. Aquaculture has become an important part of my country's fisheries. Currently, aquatic products are generally cultivated in aquaculture ponds. When draining water from the ponds or when filtration is needed, valves at the bottom of the ponds are opened to allow water to drain out through drain pipes. However, the filter screens at the drain outlets can become clogged due to debris accumulation, preventing proper drainage. Clearly, existing technology has shortcomings that urgently need to be addressed. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of the present invention is to provide a debriding device for aquaculture ponds, which has the advantage of effectively using the force of water flow to clean up the debris accumulated at the drain outlet.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A device for removing impurities from aquaculture ponds, comprising:

[0006] A water collection tank, wherein a water inlet is provided on the top wall of the water collection tank and a drain outlet is provided on the bottom wall of the water collection tank;

[0007] A rotating shaft is disposed at the water inlet and rotatably connected to the water collection tank.

[0008] A filter roller is mounted on the rotating shaft, and an elastic element is provided on the outer surface of the filter roller.

[0009] An impeller is disposed inside the filter drum and connected to the rolling shaft.

[0010] Compared to existing technologies, this application features an impeller and a filter roller mounted on a rotating shaft. Water from the aquaculture pond passes sequentially through the filter roller, the inlet of the water collection tank, and the outlet. During this process, the force of the water flow acts on the impeller mounted on the rotating shaft. The impeller, under the force of the water flow, drives the rotating shaft and the filter roller to rotate. At this time, debris in the aquaculture pond adheres to the surface of the filter roller along with the water flow and is carried into the water collection tank by the filter roller as it rotates, and then discharged from the outlet of the water collection tank. This effectively avoids the problem of debris accumulating at the outlet.

[0011] As a preferred embodiment of the present invention, the size and shape of the filter roller correspond to the size and shape of the water inlet.

[0012] As a preferred embodiment of the present invention, balls are provided inside the filtering drum.

[0013] With the above solution, balls are provided inside the filtering drum. The balls can roll as the filtering drum rotates, thereby frictionally cleaning the inside of the filtering drum and effectively preventing the accumulation of microorganisms or dirt on the filtering drum.

[0014] As a preferred embodiment of the present invention, an opening is provided on the outer surface of the filtering drum, and a movable door is movably connected to the opening.

[0015] With the above solution, the staff can clean the inside of the filtering drum through the movable door, or maintain or replace the impeller.

[0016] As a preferred embodiment of the present invention, the movable door is movably connected to the filtering drum through a hinge.

[0017] As a preferred embodiment of the present invention, a slide rail is provided at the opening, and the movable door is slidably arranged on the filtering drum through the slide rail.

[0018] As a preferred embodiment of the present invention, it further includes a rotating handle, and the rotating handle passes through the water collecting tank and is connected to the rotating shaft.

[0019] With the above solution, when too much debris causes the filtering drum to not rotate under the action of water flow and the impeller, the staff can manually rotate the rotating handle, so that the rotating shaft rotates under the action of manpower to drive the filtering drum to rotate, avoiding the problem that the filtering drum cannot rotate by itself due to excessive accumulation of debris.

[0020] As a preferred embodiment of the present invention, the elastic member is a rubber strip or a rubber ring.

[0021] With the above solution, when debris is located in the gap between the filtering drum and the water inlet or at the edge of the water inlet, there may be a situation where the debris does not enter the water collecting tank. At this time, the elastic member provided on the surface of the filtering drum can contact the debris as the filtering drum rotates, so as to bring the debris located in the gap between the filtering drum and the water inlet or at the edge of the water inlet into the water collecting tank.

[0022] As a preferred embodiment of the present invention, the impeller is made of a corrosion-resistant material.

[0023] With the above solution, the impeller is made of a corrosion-resistant material, which can effectively extend the service life of the impeller.

[0024] The above-mentioned impurity removal device for aquaculture ponds has the following beneficial effects: By arranging an impeller and a filter drum on the rotating shaft, the cooperation between the water flow and the impeller can drive the rotating shaft to rotate, and thus the filter drum also rotates along with the rotating shaft. The elastic member arranged on the filter drum can contact the sundries at the edge of the water inlet or the gap between the water inlet and the filter drum when rotating along with the filter drum, so as to bring these sundries into the water collection tank, further improving the cleaning efficiency of the sundries. Secondly, the rotating handle is connected to the rotating shaft. When too many sundries cause the water flow to not act on the impeller, the rotating shaft cannot rotate. At this time, by manually rotating the rotating handle connected to the rotating shaft, the sundries on the outer surface and around the filter drum can enter the water collection tank under the action of the elastic member and the water flow.

[0032] This invention proposes a device for removing impurities from aquaculture ponds.

[0033] Reference Figure 1 and Figure 2In one embodiment of the present invention, a fishpond impurity removal device includes: a water collection tank 1, a rotating shaft 4, a filter drum 5, and an impeller 7. The water collection tank 1 is installed on the bottom wall of the fishpond. In some preferred embodiments, the top wall of the water collection tank 1 is at the same level as or lower than the bottom wall of the fishpond. The top wall of the water collection tank 1 has a water inlet 2, and the bottom wall of the water collection tank 1 has a drain outlet 3. The drain outlet 3 is connected to an external drainage pipe or a filtration system via a pipe. The rotating shaft 4 is located at the water inlet 2 and is connected to the filter system via a pipe. The bearing is installed on the water collection tank 1; the filter drum 5 is fixedly installed on the rotating shaft 4 by screws, and the outer surface of the filter drum 5 is equipped with an elastic element 6. In this embodiment, the elastic element 6 is a rubber strip, which is fixed to the surface of the filter drum 5 by binding with iron wire. In some other embodiments, the elastic element 6 can also be a rubber ring, which is sleeved on the filter drum 5 along the axial direction of the filter drum 5, and then the rubber ring is bound and fixed to the filter drum 5 by iron wire; the impeller 7 is set inside the filter drum 5 and fixedly installed on the rolling shaft by bolts. By installing an impeller 7 and a filter roller 5 on the rotating shaft 4, the water in the aquaculture pond passes through the filter roller 5, the inlet 2 of the water collection tank 1, and the outlet 3 in sequence. During this process, the force of the water flow acts on the impeller 7 installed on the rotating shaft 4. After being subjected to the force of the water flow, the impeller 7 drives the rotating shaft 4 and the filter roller 5 to rotate. At this time, the debris in the aquaculture pond will adhere to the surface of the filter roller 5 along with the water flow, and will be carried into the water collection tank 1 by the filter roller 5 as it rotates, and then discharged from the outlet 3 of the water collection tank 1. This can effectively avoid the problem of debris accumulating at the outlet 3. When the debris is located in the gap between the filter roller 5 and the inlet 2 or at the edge of the inlet 2, there is a possibility that the debris will not enter the water collection tank 1. At this time, the elastic element 6 installed on the surface of the filter roller 5 can contact the debris as the filter roller 5 rotates, thereby bringing the debris located in the gap between the filter roller 5 and the inlet 2 or at the edge of the inlet 2 into the water collection tank 1.

[0034] Reference Figure 1 In one embodiment, the size and shape of the filter roller 5 correspond to the size and shape of the inlet 2. The filter roller 5 can be spherical or elliptical. In other embodiments, a cylindrical filter roller 5 can also be used. No limitation is made on the shape of the filter roller 5.

[0035] Reference Figure 1In one embodiment, the filter drum 5 contains ball bearings 8, which can be one or more of steel balls, stone balls, and glass balls. Different ball bearings 8 can be selected according to actual needs or cost constraints. The ball bearings 8 inside the filter drum 5 can roll as the filter drum 5 rotates, thereby performing friction cleaning on the inside of the filter drum 5 and effectively preventing the accumulation of microorganisms or dirt on the filter drum 5.

[0036] Reference Figure 1 In one embodiment, an opening is provided on the outer surface of the filter roller 5, and a movable door is movably connected to the opening. In this embodiment, the movable door is installed at the opening on the outer surface of the filter roller 5 by a hinge. In other embodiments, a slide rail can be installed on the filter roller 5, and the movable door can be embedded in the slide rail so that the movable door can slide along the slide rail, thereby allowing the staff to clean the inside of the filter roller 5 or maintain or replace the impeller 7 through the movable door.

[0037] Reference Figure 1 In one embodiment, a rotating handle is also included. The rotating handle passes through the water collection tank 1 and is connected to the rotating shaft 4. In this embodiment, the rotating handle is connected to the rotating shaft 4 by welding. In other embodiments, transmission gears can be installed on both the rotating handle and the rotating shaft 4, and the transmission connection is achieved through the meshing of the transmission gears. As long as the transmission connection between the rotating handle and the rotating shaft 4 can be achieved, the specific connection method between the rotating handle and the rotating shaft 4 is not limited here. When too much debris prevents the filter drum 5 from rotating under the action of water flow and impeller 7, the operator can manually rotate the rotating handle to make the rotating shaft 4 rotate under human force, thereby driving the filter drum 5 to rotate, avoiding the problem that the filter drum 5 cannot rotate on its own due to excessive accumulation of debris.

[0038] Reference Figure 1 In one embodiment, the impeller 7 is made of a corrosion-resistant material. In this embodiment, the impeller 7 is made of stainless steel. In other embodiments, the impeller 7 may also be made of aluminum, titanium, or plastic. No specific material is limited to the impeller 7. Making the impeller 7 of a corrosion-resistant material effectively improves its service life.

[0039] By installing an impeller 7 and a filter drum 5 on the rotating shaft 4, the rotating shaft 4 can be driven to rotate by the water flow and the impeller 7. As a result, the filter drum 5 also rotates with the rotating shaft 4. The elastic element 6 installed on the filter drum 5 can contact the debris on the edge of the water inlet 2 or the gap between the water inlet 2 and the filter drum 5 when the filter drum 5 rotates, thereby bringing these debris into the water collection tank 1, which further improves the cleaning efficiency of the debris. Secondly, the rotating handle is connected to the rotating shaft 4. When there is too much debris and the water flow cannot act on the impeller 7, the rotating shaft 4 will not be able to rotate. At this time, by manually turning the rotating handle connected to the rotating shaft 4, the debris on the outer surface of the filter drum 5 and the surrounding area can enter the water collection tank 1 under the action of the elastic element 6 and the water flow.

[0040] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
