Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture wastewater treatment equipment, specifically a freshwater aquaculture wastewater settling and sedimentation device. Background Technology

[0002] Freshwater aquaculture wastewater refers to the wastewater generated during freshwater fish farming. It contains solid impurities such as feed and feces. Before being discharged, the wastewater needs to be settled using a sedimentation device to allow the heavy debris such as sludge to settle at the bottom.

[0003] In the existing technology, people usually use a pump to draw the wastewater into the sedimentation tank, and then use the filter screen in the tank to filter out large debris. However, since the pump is installed in a fixed position, the wastewater is also discharged in a fixed position when it is added into the sedimentation tank. It cannot be evenly discharged onto the filter structure. Therefore, continuous discharge in the same position can easily cause corrosion and damage to the filter structure in the sedimentation equipment.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a freshwater aquaculture wastewater settling device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A freshwater aquaculture wastewater settling device includes a settling tank with casters at the four corners of the bottom. A cover plate is hinged to the top of the settling tank, with an inlet at the center of the top of the cover plate. A drain valve is located at the bottom of the settling tank. A filter screen is installed at the upper part of the interior of the settling tank. A limiting groove is provided in front of the inlet, with a motor mounted outside the limiting groove. A threaded screw is installed inside the limiting groove, and a guide block is sleeved on the outside of the threaded screw. A suction pump is movably mounted on the top of the guide block, with a suction pipe fixedly connected to the front end of the suction pump and a drain pipe fixedly connected to the rear end of the suction pump.

[0008] Preferably, the bottom of the suction pump is fixedly connected to a docking block, and the surface of the guide block is provided with a docking slot. By inserting the guide block into the docking slot from the side and then pushing it forward, the guide block and the suction pump can be quickly connected and assembled, making disassembly and assembly convenient.

[0009] Preferably, an extension block is fixedly connected to the front surface of the docking block, and a limiting groove is provided at the end of the inner wall of the docking slot. Positioning holes are provided inside the limiting groove and on the surface of the extension block. A fixing rod is inserted into the positioning hole. There are two sets of fixing rods, which are symmetrically arranged on both sides of the top of the guide block. Through the extension block, after the docking block is fully inserted into the docking slot, it will be inserted into the limiting groove. Then, the fixing rod is inserted into the positioning hole. This provides a limiting and fixing effect on the installed suction pump from both ends, preventing it from falling off the guide block due to vibration during the movement of the guide block, thus improving the stability of the suction pump after installation.

[0010] Preferably, a rubber anti-slip sleeve is fixedly connected to the lower part of the outer wall of the fixed plug rod, and magnetic plates are fixedly connected to the bottom end of the fixed plug rod and the inside of the positioning hole located inside the limiting slot. The two sets of magnetic plates will attract each other when the fixed plug rod is inserted into the bottom end of the positioning hole. Together with the rubber anti-slip sleeve, the stability of the fixed plug rod after insertion and installation is ensured.

[0011] Preferably, a connecting piece is fixedly connected between the two sets of fixed rods, and a protrusion is fixedly connected at the top center of the connecting piece. The surface of the protrusion has two sets of limiting pull holes. The two sets of fixed rods are connected to each other through the connecting piece. When disassembling and assembling, the two sets of fixed rods can be inserted and removed in one operation by passing a finger through the limiting pull hole on the protrusion, which further reduces the time people spend disassembling and assembling the suction pump.

[0012] Preferably, a baffle plate is hinged to the top edge of the limiting slide groove. The size of the baffle plate matches the opening size of the limiting slide groove. After the equipment is used, the baffle plate is flipped by the hinge to cover the limiting slide groove and form a sealed space, which plays a good role in protecting the threaded rod and preventing it from getting dusty and affecting the normal movement of the guide block.

[0013] Preferably, the inner edge of the shield is provided with Velcro, and a rubber sealing strip is attached to the surface of the Velcro. The rubber sealing strip increases the tightness and sealing between the shield and the limiting slide groove, further improving the shielding and protection effect.

[0014] Preferably, the limiting slide groove has an internal heat-insulating layer, and the heat-insulating layer is filled with a heat-insulating board. The heat-insulating board ensures the temperature inside the limiting slide groove and prevents the threaded screw from failing to rotate when the temperature inside the limiting slide groove drops, such as in winter.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By movably mounting the suction pump on the guide block, and the guide block being able to move horizontally on the cover plate under the action of the screw driven by the motor, the position of the suction pump can be continuously adjusted. This allows the drain pipe to evenly discharge tailwater to different positions on the filter screen, ensuring that each position is utilized evenly. This helps to improve the filtration effect during the filtration stage of the sedimentation equipment. At the same time, the suction pump and the guide block are easy to assemble and disassemble, making it convenient for people to quickly connect, assemble, and disassemble.

[0017] 2. The baffle plate, after the suction pump is removed, is flipped by the hinge to form a sealed space with the limit slide groove cover, which plays a good role in protecting the threaded rod and preventing it from getting dusty and affecting the normal movement of the guide block. The insulation plate ensures the temperature inside the limit slide groove, preventing the threaded rod from failing to rotate when the temperature inside the limit slide groove drops, such as in winter.

A suction pump 9 is movably installed on the top of the guide block 8. A suction pipe 10 is fixedly connected to the front end of the suction pump 9, and a drain pipe 11 is fixedly connected to the rear end of the suction pump 9.

[0028] In this embodiment, a docking block 13 is fixedly connected to the bottom of the suction pump 9, and a docking slot 15 is provided on the surface of the guide block 8. By inserting the guide block 8 into the docking slot 15 from the side through the docking block 13, and then pushing it forward, the guide block 8 and the suction pump 9 can be quickly connected and assembled, making disassembly and assembly convenient.

[0029] In this embodiment, an extension block 14 is fixedly connected to the front end surface of the docking block 13. A limiting groove 21 is opened at the end of the inner wall of the docking slot 15. Positioning holes 16 are opened inside the limiting groove 21 and on the surface of the extension block 14. A fixing rod 17 is inserted into the positioning hole 16. There are two sets of fixing rods 17, which are symmetrically arranged on both sides of the top of the guide block 8. After the docking block 13 is fully inserted into the docking slot 15, it will be inserted into the limiting groove 21. Then the fixing rod 17 is inserted into the positioning hole 16. The installation of the suction pump 9 is limited and fixed from both ends, preventing it from falling off the guide block 8 due to vibration during the movement of the guide block 8, thus improving the stability of the suction pump 9 after installation.

[0030] In this embodiment, a rubber anti-slip sleeve is fixedly connected to the lower part of the outer wall of the fixed plug rod 17. Magnetic plates are fixedly connected to the bottom end of the fixed plug rod 17 and the inside of the positioning hole 16 located inside the limiting slot 21. The two sets of magnetic plates will attract each other when the fixed plug rod 17 is inserted into the bottom end of the positioning hole 16. With the rubber anti-slip sleeve, the stability of the fixed plug rod 17 after insertion and installation is ensured.

[0031] In this embodiment, a connecting piece 18 is fixedly connected between the two sets of fixed insert rods 17. A protrusion 19 is fixedly connected at the top center of the connecting piece 18. Two sets of limiting pull holes are provided on the surface of the protrusion 19. The two sets of fixed insert rods 17 are connected to each other through the connecting piece 18. When disassembling and assembling, the two sets of fixed insert rods 17 can be inserted and removed in one operation by passing a finger through the limiting pull hole on the protrusion 19, which further reduces the time people spend disassembling and assembling the suction pump 9.

[0032] In this embodiment, a baffle plate 12 is hinged to the top edge of the limiting slide 5. The size of the baffle plate 12 matches the opening size of the limiting slide 5. After the equipment is used, the baffle plate 12 is flipped by the hinge to cover the limiting slide 5 and form a sealed space, which plays a good protective role for the threaded rod 7 and prevents it from getting dusty and affecting the normal movement of the guide block 8.

[0033] In this embodiment, a Velcro strip is provided on the inner edge of the shield 12, and a rubber sealing strip is attached to the surface of the Velcro strip. The rubber sealing strip increases the tightness and sealing between the shield 12 and the limiting slide groove 5, thereby further improving the shielding and protection effect.

[0034] In this embodiment, the limiting slide groove 5 is provided with an insulation layer inside, and the insulation layer is filled with an insulation board 20. The insulation board 20 ensures the temperature inside the limiting slide groove 5, and prevents the threaded screw 7 from failing to rotate when the temperature is low, such as in winter.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] In practical applications, the suction pump 9 is first inserted from the side into the docking slot 15 on the guide block 8 via the docking block 13 at its bottom. Then, it is pushed forward to initially connect the suction pump 9 and the guide block 8. After the docking block 13 is fully inserted into the docking slot 15, the extension block 14 will be inserted into the limiting slot 21. Then, the fixing rod 17 is inserted into the positioning hole 16, which limits and fixes the suction pump 9 from both ends, preventing it from being dislodged from the guide block 8 due to vibration during its movement with the guide block 8. The above operations improve the stability of the suction pump 9 after installation. After completing the above operations, start the suction pump 9, and suck out the tail water through the suction pipe 10. The drain pipe 11 discharges the tail water into the sedimentation tank 1. Since the guide block 8 can move horizontally on the cover plate 2 under the action of the screw 7 driven by the motor 6, the position of the suction pump 9 can be continuously adjusted. Therefore, the drain pipe 11 can evenly discharge tail water to different positions of the filter screen plate 4, so that each position can be evenly utilized, which helps to improve the filtration effect during the filtration stage of the sedimentation equipment.

[0037] In summary, by utilizing the above-mentioned technical solution of this utility model, the suction pump 9 is movably mounted on the guide block 8, and the guide block 8 can move horizontally on the cover plate 2 under the action of the threaded screw 7 driven by the motor 6. Therefore, the position of the suction pump 9 can be continuously adjusted, so that the drain pipe 11 can evenly discharge tailwater to different positions of the filter screen plate 4, so that each position can be evenly utilized, which helps to improve the filtration effect during the filtration stage of the sedimentation equipment. At the same time, the suction pump 9 and the guide block 8 are easy to assemble and disassemble, which is convenient for people to quickly connect, assemble and disassemble. Through the set baffle plate 12, after the suction pump 9 is removed, the hinge flips and covers the limiting slide groove 5 to form a sealed space, which plays a good role in protecting the threaded screw 7 and preventing it from being contaminated with dust and affecting the normal movement of the guide block 8. Together with the heat preservation plate 20, the temperature inside the limiting slide groove 5 is guaranteed, and the threaded screw 7 cannot rotate when the temperature inside the limiting slide groove 5 drops in low temperatures, such as in winter.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
