[0001] The invention relates to the technical field of aquaculture equipment, in particular to a vertical flow sedimentator. Background Art

[0002] Sedimentation equipment in aquaculture, commonly known as clarifiers or precipitators, is an important component of aquaculture systems for purifying and managing water quality. Its main purpose is to remove suspended particles, organic waste and microorganisms in the water, such as fish excrement, food residues, etc., to maintain a clean and healthy environment for aquaculture water. The sedimentation device settles and discharges these impurities through gravity, thereby reducing the concentration of harmful substances such as ammonia nitrogen and nitrite in the water, maintaining the stability of water quality, improving aquaculture efficiency and reducing the occurrence of aquatic product diseases.

[0003] An existing precipitator includes a precipitator box, in which a plurality of precipitator units composed of a plurality of herringbone inclined plates stacked up and down are arranged, a mud discharge channel is arranged between two adjacent precipitator units, and a mud accumulation area is arranged below the mud discharge channel. During the use of the precipitator, water to be treated is introduced into the precipitator box and is made to flow horizontally in the precipitator box, a plurality of precipitator units are used to enhance the precipitation effect of impurities in the water, and the mud discharge channel is used to make the impurities precipitated in the precipitator units fall into the mud accumulation area for accumulation.

[0004] However, during the use of existing sedimentators, since the water to be treated flows horizontally inside the sedimentator box, multiple groups of sedimentation units need to be set up to achieve sufficient precipitation of solid impurities in the water to be treated, which will lead to an increase in the volume and floor space of the sedimentator, and easily make the sedimentator unable to be used in some smaller-scale and compact sites, thereby limiting the application scenarios of the sedimentator and making the applicability of the sedimentator poor. Summary of the invention

[0005] In order to ensure the use effect of the precipitator in different application scenarios and improve the applicability of the precipitator, the present application provides a vertical flow precipitator.

When the impurities gathered at the bottom of the conical sedimentation plate need to be discharged, the plugging piece is used to release the blockage of the waste discharge pipe, so that the impurities are discharged from the waste discharge pipe. The present application makes full use of the vertical space by changing the overall flow direction of the water in the precipitator from the previous horizontal flow to the vertical flow, which helps to reduce the volume and floor space of the precipitator, thereby helping to achieve the miniaturization of the precipitator while ensuring the precipitation effect, and further helps to improve the applicability of the precipitator.

[0008] In a specific possible implementation scheme, an annular baffle is provided in the outer cylinder, the annular baffle is located at the circumferential periphery of the inner cylinder, and the liquid outlet is located at the circumferential periphery of the annular baffle, and the top of the annular baffle is arranged in a serrated shape.

[0009] By adopting the above technical solution, the annular baffle helps to intercept solid impurities in the water before the water in the upper layer of the cavity flows into the liquid outlet. At the same time, the annular baffle arranged in a serrated shape on the top helps to break up the water during the flow of the water, which helps to accelerate the escape of harmful gases in the water.

[0010] In a specific possible implementation scheme, the top surface of the inner cylinder and the top surface of the outer cylinder are located on the same horizontal plane, the top surface of the annular baffle is arranged lower than the top surface of the inner cylinder, and the liquid outlet is arranged lower than the top surface of the annular baffle.

[0012] By adopting the above technical solution, when the impurities accumulated at the bottom of the conical sedimentation plate need to be discharged, the lifting assembly is used to drive the pulling rod and the plugging head to rise, so that the plugging head releases the blockage of the waste discharge pipe, which helps to discharge the impurities accumulated at the bottom of the conical sedimentation plate to the outside through the waste discharge pipe.

[0013] In a specific feasible implementation scheme, the lifting assembly includes a placement frame, a threaded sleeve, a threaded rod and a rotating handwheel. The placement frame is fixedly arranged on the top of the outer cylinder, the threaded sleeve is penetrated through the placement frame, the threaded rod is threadedly connected to the threaded sleeve, the bottom end of the threaded rod is fixedly connected to the pulling rod, and the rotating handwheel is fixedly connected to the top end of the threaded rod.

[0014] By adopting the above technical solution, when the impurities accumulated at the bottom of the conical sedimentation plate need to be discharged, the operator turns the hand wheel to move the threaded rod upward relative to the threaded sleeve, thereby driving the pulling rod and the plugging head to move upward, so that the plugging head releases the blockage of the waste discharge pipe, thereby helping to discharge the impurities accumulated at the bottom of the conical sedimentation plate to the outside through the waste discharge pipe.

[0015] In a specific feasible implementation scheme, the pulling rod is divided into an upper rod body and a lower rod body from top to bottom, the top end of the upper rod body is fixedly connected to the threaded rod, the bottom end of the upper rod body is connected to the top end of the lower rod body, and the bottom end of the lower rod body is connected to the plugging head, the bottom end of the upper rod body is in an inverted cone shape, and the rod diameter of the lower rod body is smaller than the bottom surface diameter of the upper rod body, and the positioning tube is provided with a first placement hole and a second placement hole that are interconnected from top to bottom, the first placement hole is in an inverted cone shape and is used for the bottom end of the upper rod body to be plugged in, and the second placement hole is in a cylindrical shape and the inner diameter of the second placement hole is the same as the bottom surface diameter of the upper rod body.

[0016] By adopting the above technical scheme, when the plugging head blocks the waste discharge pipe, the bottom of the upper rod body is fixedly inserted in the first placement hole, so that the first placement hole is in a blocked state; in the process of the plugging head releasing the blockage of the waste discharge pipe, the plugging head, the upper rod body and the lower rod body move upward synchronously, so that the first placement hole is gradually released from the blocking state, which helps to make the impurities precipitated and accumulated at the bottom of the inner cylinder body be discharged into the conical sedimentation plate through the first placement hole and the second placement hole, and then discharged through the waste discharge pipe.

[0017] In a specific implementation scheme, a stirring spiral is provided on the circumferential outer fixed sleeve of the lower rod body. The stirring spiral is located at one end of the lower rod body close to the upper rod body, and the outer diameter of the stirring spiral is the same as the inner diameter of the second placement hole.

[0018] By adopting the above technical solution, during the process of synchronously moving the sealing head, the upper rod body and the lower rod body upward, the sealing head, the upper rod body and the lower rod body will rotate, which will help drive the stirring spiral to stir the inner bottom of the inner cylinder, thereby helping to prevent the first placement hole and the second placement hole from being blocked, and helping to improve the discharge effect of precipitated impurities inside the inner cylinder.

[0019] In a specific feasible implementation scheme, the blocking member is a solenoid valve, which is arranged on the waste discharge pipe and is used to control the on-off of the waste discharge pipe. An anti-blocking component for preventing blockage of the waste discharge pipe is arranged in the conical sedimentation plate, and a transmission component for driving the anti-blocking component to operate is arranged in the inner cylinder.

The transmission component helps to transmit the impact force of the water spraying out of the liquid inlet pipe to the anti-blocking component, so as to prevent the accumulated impurities from blocking the waste discharge pipe, thereby helping to ensure the discharge effect of the impurities accumulated at the bottom of the conical sedimentation plate.

[0021] In a specific possible implementation scheme, the anti-blocking component includes a mounting frame, a rotating shaft and a pusher blade. The mounting frame is fixedly arranged on the inner wall of the waste discharge pipe, the rotating shaft is rotatably arranged on the mounting frame and is transmission-connected to the transmission assembly, and the pusher blade is arranged on the circumferential side wall of the rotating shaft.

[0022] By adopting the above technical solution, the transmission component is used to transmit the impact force of the water spraying out of the liquid inlet pipe to the rotating shaft, thereby driving the rotating shaft to rotate, and then the pushing blades stir and push the impurities entering the waste discharge pipe, thereby helping to ensure the discharge effect of the impurities accumulated at the bottom of the conical sedimentation plate.

[0023] In a specific feasible implementation scheme, the transmission assembly includes a fixed sleeve, a transmission shaft and rotating blades. The fixed sleeve is arranged through the bottom wall of the inner cylinder, the transmission shaft is rotatably connected to the fixed sleeve, and the bottom end of the transmission shaft is fixedly connected to the rotating shaft, and the rotating blades are arranged on the transmission shaft and located above the water outlet of the liquid inlet pipe.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application helps to change the overall flow direction of water in the precipitator from the previous horizontal flow to the vertical flow through the arrangement of the outer cylinder, the inner cylinder and the conical sedimentation plate, making full use of the vertical space, helping to reduce the volume and floor space of the precipitator, thereby helping to achieve the miniaturization of the precipitator while ensuring the sedimentation effect, and further helping to improve the applicability of the precipitator; 2.

[0038] Reference Figure 1 and Figure 2 When treating the water body, the operator transports the water body to be treated to the inner cylinder 2 through the liquid inlet pipe 5. When the water body fills the inner cylinder 2, the water body will overflow from the top opening of the inner cylinder 2 into the cavity 4.

[0039] Reference Figure 1 and Figure 2 When the water passes through the top of the annular baffle 8, the serrated setting at the top of the annular baffle 8 helps to intercept solid impurities in the water, and also helps to break up the water during the flow of the water, thereby accelerating the escape of harmful gases in the water.

[0040] Reference Figure 2 and Figure 3In this embodiment, the plugging member is a plugging head 9. The plugging head 9 is clamped and placed at the connection between the waste discharge pipe 7 and the conical sedimentation plate 3. A pulling rod 10 is fixedly connected to the plugging head 9, and a positioning tube 11 is fixedly installed at the bottom of the inner cylinder 2. In this embodiment, the pulling rod 10 includes an upper rod body 101 and a lower rod body 102. The bottom end of the lower rod body 102 is fixedly connected to the plugging head 9, the top end of the lower rod body 102 is fixedly connected to the bottom end of the upper rod body 101, and the bottom end of the upper rod body 101 is in an inverted cone shape, and the rod diameter of the lower rod body 102 is smaller than the bottom surface diameter of the upper rod body 101; the positioning tube 11 is provided with a first placement hole 13 and a second placement hole 14 from top to bottom in sequence. The first placement hole 13 is in an inverted cone shape and matches the shape of the bottom end of the upper rod body 101, and the second placement hole 14 is cylindrical and its inner diameter is the same as the bottom surface diameter of the upper rod body 101. A stirring screw 15 is fixedly sleeved on the circumferential outer wall of the lower rod body 102 close to one end of the upper rod body 101 , and the outer diameter of the stirring screw 15 is the same as the inner diameter of the second placement hole 14 .

[0041] Reference Figure 2 A lifting assembly 12 is provided at the top of the outer cylinder 1, and the lifting assembly 12 includes a placement frame 121, a threaded sleeve 122, a threaded rod 123 and a rotating hand wheel 124.

[0042] Reference Figure 2 When discharging the impurities accumulated at the bottom of the conical sedimentation plate 3, the operator turns the hand wheel 124, so that the threaded rod 123 moves upward under the guidance of the threaded sleeve 122, thereby driving the pulling rod 10 and the plugging head 9 to move upward synchronously, so that the plugging head 9 releases the blockage of the waste discharge pipe 7, which helps to discharge the impurities accumulated at the bottom of the conical sedimentation plate 3 to the outside through the waste discharge pipe 7.

[0043] Reference Figure 2 and Figure 3When the threaded rod 123 drives the pulling rod 10 to move upward, the upper rod body 101 gradually moves away from the hole wall of the first placement hole 13 during the upward movement, so that the first side charge is no longer blocked, so that the first placement hole 13 is gradually unblocked, which helps to discharge the impurities precipitated and accumulated at the bottom of the inner cylinder 2 through the first placement hole 13 and the second placement hole 14 into the conical precipitation plate 3, and then discharged through the waste discharge pipe 7. While the pulling rod 10 moves upward, the upper rod body 101 and the lower rod body 102 rotate driven by the threaded rod 123, thereby driving the stirring screw 15 to stir the inner bottom of the inner cylinder 2, which helps to prevent the first placement hole 13 and the second placement hole 14 from being blocked, and helps to improve the discharge effect of the precipitated impurities inside the inner cylinder 2.

[0044] The implementation principle of the embodiment of the present application is as follows: when treating the water body, the operator transports the water body to be treated to the inner layer cylinder 2 through the liquid inlet pipe 5.

When the water body fills the cavity 4, the water body in the upper layer of the cavity 4 will overflow from the top of the annular baffle 8 to the periphery of the annular baffle 8 and be discharged through the liquid outlet 6. The present application helps to make the water body flow vertically, makes full use of the vertical space, helps to reduce the volume and floor space of the precipitator, thereby helping to achieve the miniaturization of the precipitator under the premise of ensuring the precipitation effect, and then helps to improve the applicability of the precipitator.

[0045] When water passes through the top of the annular baffle 8, the serrated setting at the top of the annular baffle 8 helps to intercept solid impurities in the water, and also helps to break up the water during the flow of the water, thereby accelerating the escape of harmful gases in the water.

[0046] When discharging the impurities accumulated at the bottom of the conical sedimentation plate 3, the operator turns the hand wheel 124, so that the threaded rod 123 moves upward under the guidance of the threaded sleeve 122, thereby driving the pulling rod 10 and the plugging head 9 to move upward synchronously, so that the plugging head 9 releases the blockage of the waste discharge pipe 7, thereby helping to discharge the impurities accumulated at the bottom of the conical sedimentation plate 3 to the outside through the waste discharge pipe 7.

[0047] When the threaded rod 123 drives the pulling rod 10 to move upward, the upper rod body 101 gradually moves away from the hole wall of the first placement hole 13 during the upward movement, so that the first side charge is no longer blocked, so that the first placement hole 13 is gradually unblocked, which helps to discharge the impurities precipitated and accumulated at the bottom of the inner cylinder 2 through the first placement hole 13 and the second placement hole 14 into the conical precipitation plate 3, and then discharged through the waste discharge pipe 7. While the pulling rod 10 moves upward, the upper rod body 101 and the lower rod body 102 rotate driven by the threaded rod 123, thereby driving the stirring screw 15 to stir the inner bottom of the inner cylinder 2, which helps to prevent the first placement hole 13 and the second placement hole 14 from being blocked, and helps to improve the discharge effect of the precipitated impurities inside the inner cylinder 2.

[0048] Embodiment 2: Reference Figure 4 and Figure 5 The difference between the embodiment of the present application and the embodiment 1 is that, in the embodiment, the blocking member is a solenoid valve 16, and the solenoid valve 16 is fixedly installed on the waste discharge pipe 7. An anti-blocking component 17 is provided at the connection position between the waste discharge pipe 7 and the conical sedimentation plate 3, and a transmission component 18 is provided in the inner cylinder 2.

[0051] Reference Figure 5 and Figure 6When the impurities accumulated at the bottom of the conical sedimentation plate 3 need to be discharged, the operator controls the solenoid valve 16 to release the blockage of the waste discharge pipe 7. At the same time, the rotating blades 183 rotate under the impact force of the water sprayed from the liquid inlet pipe 5, thereby driving the transmission shaft 182, the rotating shaft 172 and the multiple groups of pushing blades 173 to rotate synchronously. The multiple groups of pushing blades 173 stir and push the impurities entering the waste discharge pipe while rotating, thereby helping to prevent the impurities from causing blockage of the waste discharge pipe 7, and further helping to ensure the discharge effect of the impurities accumulated at the bottom of the conical sedimentation plate 3.
