Description

Technical Field

[0001] This invention relates to the field of white goose breeding technology, and more specifically, to an automated water circulation device for white goose breeding ponds. Background Technology

[0002] White geese are common animals. In artificial breeding, they are fed in cement-built feeding pools. However, after long-term use, wastewater and pollutants inside these feeding pools are difficult to remove, thus affecting the geese's living environment.

[0003] Chinese Patent Publication No. CN214801775U discloses a water circulation device for swan breeding ponds, which solves the problem of difficult cleaning of sewage and pollutants inside the feeding ponds of swan breeding. It includes a base, a sliding plate, a conveyor belt, and a collection box. The base has a feeding pool and a filtration pool at its top two ends, respectively. The sliding plate slides along the length of the base top. The conveyor belt is inclined and fixed above the sliding plate by a support rod. The collection box is slidably connected to the feeding pool, and has a trapezoidal inlet on its side wall. The collection box is connected to the side wall of the sliding plate by a second support rod. One end of the conveyor belt is located inside the collection box, and the bottom of the other end of the conveyor belt is fixed with a guide plate facing the filtration pool.

[0004] In existing technologies, when a single, large, centralized sludge tank is used to collect sludge particles, sludge accumulation occurs locally. When the amount of sludge is large, it can easily cause blockages in the sludge discharge pipes. However, by setting up multiple sludge tanks, the sludge can be collected in a dispersed manner, with each tank containing a relatively small amount of sludge, reducing the risk of blockages and ensuring the normal operation of the sludge discharge system.

[0005] However, when there are multiple sludge tanks, refer to Figure 2 As shown, due to gravity, sludge particles will sink into the sludge tank. Therefore, there are more sludge particles in the sludge tank near the inlet than in the other tanks at the back. Thus, if an electric valve is installed in each sludge tank, it will increase the operating cost. In addition, the sludge particles will pass through the inclined tube first, and the impurities they carry can easily block the inclined tube near the inlet, affecting the smooth flow of the inclined tube. Summary of the Invention

[0006] This invention provides an automated water circulation device for goose farming ponds. The valve plate moves up to reduce the overlapping area of ​​the square trough and the through trough, thereby solving the problem mentioned in the background art, namely: uneven distribution of sludge particles in the sludge tank.

[0007] To achieve the above objectives, an automated water circulation device for goose farming includes a treatment tank, a secondary water tank, a sludge collection trough, and a stirring device. The treatment tank is connected to the secondary water tanks on both sides, and the treatment tank has an inlet pipe, while the secondary water tanks have outlet pipes. The treatment tank has a dividing plate inside, which divides the interior of the treatment tank into a premixing zone for mixing with flocculant and a settling zone for sludge sedimentation. The dividing plate has a through groove to connect the premixing zone and the settling zone. An inclined pipe is installed in the settling zone, which divides the upper part of the settling zone into an outlet zone and the lower part into an inlet zone. A flow-limiting mechanism is configured in the premixing zone. The flow-limiting mechanism includes a flow-limiting plate and a flow-guiding mechanism. The flow-guiding mechanism drives the flow-limiting plate to move back and forth in the inlet zone according to the liquid level change in the auxiliary water tank. The flow-limiting plate is attached to the bottom of the inclined tube. In the initial stage, the liquid in the premixing zone is transported from the through channel to the inlet zone. During the process of the liquid rising in the auxiliary water tank, the guiding mechanism lifts the liquid at the through channel upwards, so as to reduce the liquid flow space at the through channel and promote the liquid to carry sludge to the far end. Furthermore, when the liquid in the auxiliary water tank reaches the preset level, the guiding mechanism drives the flow limiting plate to move to the far end, peeling off the impurities at the joint between the inclined tube and the flow limiting plate, and working together to lift the liquid to impact the peeled impurities.

[0008] The flow guiding mechanism includes a valve plate that is movably disposed on one side of the dividing plate in the longitudinal direction. The valve plate is located in the premixing zone and has a square groove of the same size as the through groove.

[0009] Under normal conditions, the square channel and the through channel are in an overlapping state. When the valve plate moves up, the square channel and the through channel are in a misaligned state, so that the overlapping position of the square channel and the through channel is reduced, guiding the liquid to the far end of the sedimentation zone.

[0010] A guide plate is fixedly installed on one side of the valve plate, and the other end of the guide plate passes through the channel and extends into the sedimentation zone.

[0011] The guide plate has a lower end and a raised end. One end of the guide plate is the lower end and the other end is the raised end, which is fixed to the valve plate. The lower end smoothly transitions to the raised end to transport the liquid upward.

[0012] A vertical rod is fixedly connected to the top of the valve plate. Both ends of the vertical rod extend into the auxiliary water tank, and a float is fixed to its end. When the liquid level in the auxiliary water tank reaches the preset water level, the float drives the vertical rod to move upward, raising the square groove to a state of misalignment with the through groove.

[0013] One end of the flow restrictor plate passes through and slides through the dividing plate, while the other end is attached to the bottom of the inclined tube. The flow restrictor plate has several drainage holes at the attachment point with the inclined tube, and the drainage holes have the same cross-section as the inlet of the liquid flow channel.

[0014] In the initial state, the drain hole and the inlet of the liquid flow channel are aligned. When the drain hole and the inlet of the liquid flow channel are misaligned, the flow restrictor is used to remove impurities blocking the inlet and reduce the size of the inlet so that the liquid can be transported into the distant liquid flow channel.

[0015] A top plate is fixedly installed on one side of the valve plate. The flow limiting plate at the top of the top plate has a wedge block, and a tension spring is elastically connected between the flow limiting plate and the dividing plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In this automated water circulation device for goose farming ponds, the overlapping area of ​​the square trough and the through trough is reduced by the upward movement of the valve plate, which increases the flow velocity of the liquid. At the same time, the flow limiting plate is driven to make a lateral displacement. The flow limiting plate removes impurities at the inlet, and then the liquid is transported to the flow limiting plate through the guide plate. The liquid impacts the removed impurities, thereby preventing impurities from clogging the inlet. At the same time, it improves the uniformity of sludge particle distribution in several sludge collection tanks. Attached Figure Description

[0019] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] To address the issue of uneven sludge particle distribution in sludge tanks, this invention discloses an automated water circulation device for goose farming ponds. (Refer to...) Figures 1-3 As shown, the system includes a treatment tank 100, an auxiliary water tank 101, a sludge collection tank 104, and a stirring device 105. The treatment tank 100 is connected to the two auxiliary water tanks 101 on both sides. The treatment tank 100 has an inlet pipe 102, and the auxiliary water tanks 101 have outlet pipes 103. The treatment tank 100 has a dividing plate 110 inside, which divides the interior of the treatment tank 100 into a premixing zone 111 for mixing with flocculant and a settling zone 112 for sludge sedimentation. Therefore, through the pump body... The mixture of sludge and water in the aquaculture pond is pumped into the premixing zone 111. At the same time, flocculant is added to the premixing zone 111. With the stirring action of the stirring device 105, the mixture and flocculant are initially mixed in the premixing zone 111. Then, a through groove 113 is provided on the dividing plate 110 to connect the premixing zone 111 and the sedimentation zone 112. An inclined tube 120 is provided in the sedimentation zone 112. The inclined tube 120 divides the upper part of the sedimentation zone 112 into an outlet zone and the lower part into an inlet zone. Next, the sludge-containing water enters the sedimentation zone 112 from one end of the premixing zone 111 through the channel 113. It is then transported to the upper effluent zone via the sedimentation zone 112 and the inclined tube 120. Specifically, in the sedimentation zone 112, the heavier particles enter through the channel 113 and fall directly into the sludge collection tank 104, while the lighter sludge particles are carried to the effluent zone and slide down along the inclined tube 120 under gravity. Meanwhile, the clean water flows upward, thus achieving sludge-water separation.

[0021] The inclined tube 120 is located inside the treatment tank 100, with one side extending to the dividing plate 110. The inclined tube 120 has several inclined liquid flow channels 121 inside, which connect the lower inlet area and the upper outlet area. In this way, the liquid in the sedimentation zone 112 can enter through the inlet of the liquid flow channel 121 and then be discharged at the outlet at the top. The sludge particles slide down to the bottom along the liquid flow channel 121 under the action of gravity, while the clean water flows from the outlet area into the auxiliary water tank 101.

[0022] A flow-limiting mechanism 130 is configured in the premixing zone 111. The flow-limiting mechanism 130 includes a flow-limiting plate 131 and a flow-guiding mechanism. The flow-guiding mechanism drives the flow-limiting plate 131 to reciprocate within the inlet zone according to the liquid level change in the auxiliary water tank 101. The flow-limiting plate 131 is in contact with the bottom of the inclined tube 120. In the initial stage, the liquid in the premixing zone 111 is transported from the through channel 113 to the inlet zone. During the liquid rise process in the auxiliary water tank 101, the guiding mechanism lifts the liquid at the through channel 113 upwards to narrow the through channel. The 113 liquid flow spaces facilitate the transport of liquid carrying sludge to distant locations. Furthermore, when the liquid in the auxiliary water tank 101 reaches the preset level, the guiding mechanism drives the flow limiting plate 131 to move to distant locations, peeling off impurities at the point where the inclined tube 120 and the flow limiting plate 131 are attached. The liquid is also lifted to impact the peeled impurities, thereby preventing impurities from clogging the inlet of the liquid flow channel 121. At the same time, the upward-lifted water flow can also be transported to distant locations, so that sludge particles can be evenly distributed in several sludge collection tanks 104.

[0023] First, the specific structure of the diversion mechanism is disclosed. The diversion mechanism includes a valve plate 132 that is movably disposed on one side of the dividing plate 110 in the longitudinal direction. The valve plate 132 is located within the premixing zone 111, and the valve plate 132 has a square groove 133 of the same size as the through groove 113. Under normal conditions, the square groove 133 and the through groove 113 are in an overlapping state, so that the mixed liquid in the premixing zone 111 can be smoothly transported from the square groove 133 and the through groove 113 to the sedimentation zone 112. Then, combined with Figure 4 , Figure 5 As shown, a vertical rod 135 is provided on the top of the valve plate 132. Both ends of the vertical rod 135 extend into the auxiliary water tank 101, and each end has a float ball 136. During the process of clear water being transported from the outlet area into the auxiliary water tank 101, the water level in the auxiliary water tank 101 gradually rises. When the water level in the auxiliary water tank 101 reaches the preset water level (the water level in the auxiliary water tank 101 drives the float ball 136 to float upward), the float ball 136 drives the vertical rod 135 to move upward. During this process, the square groove 133 is raised to change from an overlapping state to a misaligned state with the through groove 113.

[0024] It should also be understood that when the water flow in the auxiliary water tank 101 comes into contact with the float 136, it can also be matched and combined with the hydraulic rod (not shown in the figure) so that the buoyancy of the float 136, together with the external power of the hydraulic rod, drives the upright 135 to move upward, thereby realizing the upward movement of the valve plate 132.

[0025] During operation, when clean water is first introduced into the auxiliary water tank 101 in the inlet area, the through channel 113 and the square channel 133 are completely overlapped. As the liquid level in the auxiliary water tank 101 gradually rises, the liquid level in the auxiliary water tank 101 comes into contact with the float ball 136. During the process of reaching the preset water level, the valve plate 132 moves upward. The square channel 133 and the through channel 113 are misaligned, so that the overlapping position of the square channel 133 and the through channel 113 is reduced. That is, the liquid cross section flowing out from the overlapping position of the liquid through channel 113 and the square channel 133 is reduced, and the flow velocity is increased, thereby guiding the liquid to the far end of the sedimentation zone 112. The sludge particles carried in the liquid can be transported to the sludge collection tank 104 further away, so that the sludge particles can be evenly accumulated in several sludge collection tanks 104. At the same time, return to Figure 3 As shown, a guide plate 134 is provided on one side of the valve plate 132. The other end of the guide plate 134 passes through the through groove 113 and extends into the sedimentation zone 112. The guide plate 134 has a lower end and a raised end. One end of the guide plate 134 is the lower end, and the other end is the raised end, which is fixed to the valve plate 132. The lower end smoothly transitions to the raised end. When the guide plate 134 moves from... Figure 2 As the solid line portion moves upward to the dashed line portion, the overlapping area of ​​the through channel 113 and the square channel 133 gradually shrinks, and the overall height of the guide plate 134 is raised. The guide plate 134 guides the liquid from the lower end to the raised end to transport the liquid upward. As the height of the liquid flow increases, the overlapping area of ​​the through channel 113 and the square channel 133 shrinks, which increases the flow velocity of the liquid so that the liquid can flow to the far end, further improving the uniformity of the distribution of sludge particles in the several sludge collection tanks 104.

[0026] Furthermore, in combination Figure 6 , Figure 7 As shown, one end of the flow limiting plate 131 passes through the dividing plate 110 and slides laterally therewith, while the other end is attached to the bottom of the inclined tube 120. The flow limiting plate 131 and the inclined tube 120 are attached to each other and have several drainage holes 139. The drainage holes 139 have the same cross-section as the inlet of the liquid flow channel 121. In the initial state, the drainage holes 139 and the inlet of the liquid flow channel 121 are overlapped. The liquid located in the sedimentation zone 112 is transported to the outlet zone through the drainage holes 139 and the liquid flow channel 121.

[0027] Because the liquid contains sludge particles and impurities, and the inlet of the liquid flow channel 121 near the through channel 113 is more likely to be blocked, the reason is that the inlet of the liquid flow channel 121 near the through channel 113 is close to the through channel 113, and the drain hole 139 in the initial state is completely overlapped with the liquid flow channel 121. Therefore, the water flowing out from the through channel 113 will first enter through the inlet of the liquid flow channel 121 in this area, and then enter the outlet area. Thus, when liquid flows through the inlet of liquid flow channel 121, impurities can easily clog the inlet, affecting liquid flow. At this time, combined with... Figure 8 As shown, as the valve plate 132 moves upward, a top plate 137 is provided on one side of the top of the valve plate 132. The flow-limiting plate 131 at the top of the top plate 137 has a wedge, and a tension spring 138 is elastically connected between the flow-limiting plate 131 and the dividing plate 110. Thus, when the top plate 137 contacts the wedge, the top plate 137 applies pressure to the wedge, forcing the flow-limiting plate 131 to overcome the elastic potential energy of the tension spring 138 and move to one side. During this process, refer to... Figure 7 As shown, the drain hole 139 moves to a state where it is misaligned with the inlet of the liquid flow channel 121. When the drain hole 139 and the inlet of the liquid flow channel 121 are... Figure 7 In the misaligned state, the flow restrictor 131 is used to remove impurities blocking the inlet and reduce the size of the inlet, restricting the flow of liquid from the inlet of the liquid flow channel 121 in that area, and the flow restrictor 131 moves to one side, thereby conveying the liquid to the inlet of the far liquid flow channel 121.

[0028] Furthermore, during the process of the flow restrictor 131 removing impurities that were blocking the inlet of the liquid flow channel 121, Figure 6 The upward movement of the guide plate 134 in the middle guides the liquid flowing upward, thereby dispersing the stripped impurities and preventing impurities from accumulating at the inlet. It should be added that, for reference Figure 8 As shown, the upright 135 extends out from the flow limiting plate 131, and the flow limiting plate 131 corresponding to the upright 135 has a slot so that the flow limiting plate 131 can reserve space when it moves laterally.

[0029] In other words, by moving the valve plate 132 upward, the overlapping area of ​​the square channel 133 and the through channel 113 is reduced, increasing the flow velocity of the liquid. Simultaneously, this drives the flow-limiting plate 131 to move laterally, causing it to peel off impurities at the inlet. The liquid is then transported to the flow-limiting plate 131 via the guide plate 134, creating an impact that prevents impurities from clogging the inlet. This also improves the uniformity of sludge particle distribution within the several sludge collection tanks 104. Thus, by ensuring uniform distribution of sludge particles within the several sludge collection tanks 104, and by connecting the tanks together to uniformly discharge the sludge, the need for internal liquid extraction is reduced, improving the treatment efficiency.

[0030] When the liquid level in the auxiliary water tank 101 reaches the preset level (detected by a liquid level sensor), the electric valve at the outlet pipe 103 opens to discharge the liquid in the auxiliary water tank 101. Then, the valve plate 132 descends and resets until the square groove 133 and the through groove 113 are completely aligned. Meanwhile, the flow limiting plate 131 moves in the opposite direction and resets under the elastic action of the tension spring 138. Finally, the clean water discharged from the outlet pipe 103 is finely filtered and then transported to the aquaculture pond to achieve the purpose of recycling.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
