Description

Technical Field

[0001] The present invention relates to the field of water treatment, and particularly to a livestock breeding water treatment device and a treatment method thereof. Background Art

[0002] A livestock breeding water treatment device is a device used to treat the wastewater generated during livestock breeding, and is usually applied to places such as farms and slaughterhouses. Such devices treat wastewater through physical, chemical or biological methods to remove pollutants therein and meet the discharge standards or reuse requirements. Livestock breeding water treatment devices are widely used in large-scale farms, ecological agricultural parks and areas with high environmental protection requirements. By using water treatment devices, the pollution of wastewater to the environment can be effectively reduced, the recycling of water resources can be promoted, and the ecological environment around the farms can be improved.

[0003] In practical applications, a livestock breeding water treatment device usually includes a pretreatment unit, a core treatment unit and a post-treatment unit. The wastewater first passes through the pretreatment unit to remove larger suspended solids and impurities, then enters the core treatment unit for deep purification, and finally the water quality is further optimized through the post-treatment unit. However, in the prior art, the removal efficiency of the pretreatment unit for suspended solids is low, which easily leads to an increase in the load of the subsequent treatment unit and affects the overall treatment effect. In addition, during the treatment process, the structural design of some devices is not reasonable enough, which may cause uneven wastewater flow velocity or uneven distribution of treatment agents, thereby affecting the treatment efficiency and the quality of the effluent. These problems make the device need to be frequently maintained during operation, increasing the operation cost and management difficulty. Summary of the Invention

[0011] Optionally, the support frame includes four columns fixedly installed at the bottom of the device. The columns are connected by cross beams. Slide rails are arranged on the cross beams, and both ends of the slide rails are fixed to the cross beams by bolts. The adjusting plate is connected to the slide rails through sliders, and balls are arranged at the bottom of the sliders to reduce friction.

[0012] Optionally, the driving mechanism includes a stepper motor fixedly installed on one side of the support frame. The output shaft of the stepper motor is connected to a lead screw through a coupling. The lead screw penetrates through the adjusting plate and is threadedly connected to the adjusting plate. Limit blocks are arranged on both sides of the adjusting plate, and the limit blocks cooperate with the slide rails to prevent the adjusting plate from shifting.

[0013] Optionally, the multi-layer filtering assembly includes a bracket fixedly installed inside the solid-liquid separation unit. Multiple groups of card slots are arranged on the bracket, and the filter plates are fixed to the bracket through the card slots. The inclination angle of the filter plates is 15° to 30°, and the pore diameters of the filter holes are 5 mm, 3 mm, and 1 mm from top to bottom in sequence.

[0014] Optionally, the stirring assembly includes a driving motor fixedly installed on the top of the medicament mixing unit. The output shaft of the driving motor is connected to a main shaft through a coupling. Multiple groups of mounting seats are arranged on the main shaft, and the rotating blades are fixed to the main shaft through the mounting seats. The number of rotating blades is 6 to 8, and the width of the diversion channels is 2 mm to 5 mm.

[0015] Optionally, the multi-stage transmission mechanism includes a first gear fixedly installed on the main shaft. The first gear meshes with a second gear. The second gear is connected to a third gear through a transmission shaft. The third gear meshes with a fourth gear. The fourth gear is fixedly installed on an auxiliary shaft, and multiple auxiliary blades are arranged on the auxiliary shaft. The auxiliary blades are used to enhance the mixing effect of the medicament.

[0016] Optionally, the diversion plate includes an arc-shaped plate fixedly installed on the inner wall of the precipitation unit. A plurality of drainage holes are arranged on the inner side of the arc-shaped plate. The diameter of the drainage holes is 10 mm to 20 mm, the spacing between the drainage holes is 50 mm to 100 mm, and the radius of curvature of the arc-shaped plate is 500 mm to 800 mm.

[0017] On the other hand, the present invention provides a treatment method for a livestock breeding water treatment device, which is applied to the above livestock breeding water treatment device. The method includes the following steps:

[0018] Step 1: Introduce the aquaculture wastewater into the device through the inlet unit, start the drive mechanism to drive the adjustment plate to move along the slide rail, and adjust the flow rate of the wastewater flowing into the solid-liquid separation unit;

[0019] Step 2: After the wastewater enters the solid-liquid separation unit, it is filtered step by step through the multi-layer filtration component. Larger suspended solids are intercepted on the filter plate, and smaller particulate matters flow with the wastewater to the next unit;

[0020] Step 3: After the wastewater enters the chemical mixing unit, start the drive motor to drive the stirring component to rotate. The diversion grooves on the rotating blades guide the wastewater to form a vortex. At the same time, drive the auxiliary blades to rotate through the multi-stage transmission mechanism to enhance the mixing effect of the chemicals;

[0021] Step 4: The mixed wastewater enters the sedimentation unit, and the wastewater is shunted through the arc structure and drainage holes of the diversion plate. The suspended solids in the wastewater settle under the action of gravity, and the clear water is discharged from the outlet of the sedimentation unit;

[0022] Step 5: Regularly clean the filter plate in the solid-liquid separation unit and the sediment in the sedimentation unit to maintain the normal operation of the device.

[0023] Compared with the prior art, the present invention has the following beneficial technical effects:

[0024] By setting an adjustment plate in the inlet unit and combining it with the drive mechanism, the movement of the adjustment plate can change the flow rate of the wastewater flowing into the solid-liquid separation unit. When the adjustment plate moves to one side, the flow area of the wastewater increases and the flow rate decreases; when the adjustment plate moves to the other side, the flow area of the wastewater decreases and the flow rate increases. This design enables the flow rate of the wastewater to be precisely controlled according to actual needs, avoiding the decline in treatment effect caused by too fast or too slow flow rate.

[0025] By setting a multi-layer filtration component in the solid-liquid separation unit, the inclined arrangement of the filter plate makes it easier for suspended solids to slide down to the collection area under the action of gravity, and the design that the aperture of the filter holes gradually decreases from top to bottom can achieve step-by-step filtration, effectively improving the removal efficiency of suspended solids. In addition, the filter plate is fixed to the bracket through the card slot, which is convenient for disassembly and cleaning, reducing the maintenance cost.

[0026] By setting a stirring component and a multi-stage transmission mechanism in the chemical mixing unit, the diversion grooves on the rotating blades can guide the wastewater to form a vortex, enhancing the contact area between the wastewater and the chemicals, and the multi-stage transmission mechanism driving the auxiliary blades to rotate further improves the mixing uniformity of the chemicals. This design enables the chemicals to be quickly and evenly dispersed in the wastewater, thereby improving the working efficiency of the subsequent treatment unit.

[0027] By setting an arc-shaped deflector and drainage holes in the precipitation unit, the arc-shaped structure can effectively disperse the flow direction of the wastewater, avoiding the direct impact of the water flow on the precipitation area. The design of the drainage holes can further refine the wastewater diversion process, ensuring that the suspended solids in the wastewater can fully settle under the action of gravity. This design significantly improves the treatment effect of the precipitation unit and reduces the content of suspended solids in the effluent.

[0028] In summary, by optimizing the structural design and process flow, the present invention solves the problems of low efficiency of suspended solid removal, uneven wastewater flow velocity, and uneven chemical agent distribution in the prior art, and significantly improves the overall performance and operation efficiency of the livestock breeding water treatment device.

[0033] The livestock breeding water treatment device of the present invention mainly includes a water inlet unit 1, a solid-liquid separation unit 2, a chemical agent mixing unit 3 and a precipitation unit 4. Each unit is connected by pipelines to form a complete wastewater treatment process. The support frame 5 is fixedly installed at the bottom of the device. Its structure consists of four columns and crossbeams. Slide rails 6 are arranged on the crossbeams. The two ends of the slide rails 6 are fixed to the crossbeams by bolts. The adjusting plate 7 is connected to the slide rails 6 through sliders. Ball bearings are arranged at the bottom of the sliders to reduce friction. The movement of the adjusting plate 7 is controlled by a driving mechanism. The driving mechanism includes a stepping motor fixedly installed on one side of the support frame 5. The output shaft of the stepping motor is connected to a lead screw through a coupling. The lead screw passes through the adjusting plate 7 and is threadedly connected to the adjusting plate 7. Limit blocks are arranged on both sides of the adjusting plate 7. The limit blocks cooperate with the slide rails 6 to prevent the adjusting plate 7 from shifting.

[0034] Inside the solid-liquid separation unit 2, there are multiple layers of filter components 8. The multiple layers of filter components 8 include a bracket fixedly installed inside the solid-liquid separation unit 2. There are multiple groups of card slots on the bracket, and the filter plates 9 are fixed to the bracket through the card slots. The number of filter plates 9 is three, and each filter plate 9 is arranged obliquely, with an inclination angle of 15° to 30°. Multiple groups of filter holes are provided on the filter plate 9, and the pore diameters of the filter holes are 5 mm, 3 mm, and 1 mm from top to bottom in sequence. The inclined arrangement of the filter plate 9 enables the suspended matter to slide more easily to the collection area under the action of gravity, and the design of gradually decreasing filter holes can achieve the hierarchical interception of suspended matter with different particle sizes. After the wastewater enters from the inlet unit 1, through the flow rate control of the regulating plate 7, it enters the solid-liquid separation unit 2 and is gradually filtered through the multiple layers of filter components 8. Larger suspended matter is intercepted on the filter plate 9, and smaller particulate matters flow with the wastewater to the chemical mixing unit 3.

[0035] Inside the chemical mixing unit 3, there is a stirring component, and the stirring component is connected to the driving motor through a multi-stage transmission mechanism. The stirring component includes a driving motor fixedly installed on the top of the chemical mixing unit 3. The output shaft of the driving motor is connected to the main shaft through a coupling. Multiple groups of mounting seats are provided on the main shaft, and the rotating blades are fixed to the main shaft through the mounting seats. The number of rotating blades is 6 to 8, and diversion grooves are provided on the rotating blades, and the width of the diversion grooves is 2 mm to 5 mm. The multi-stage transmission mechanism includes a first gear fixedly installed on the main shaft. The first gear meshes with the second gear. The second gear is connected to the third gear through a transmission shaft. The third gear meshes with the fourth gear. The fourth gear is fixedly installed on the auxiliary shaft, and multiple auxiliary blades are provided on the auxiliary shaft. After the wastewater enters the chemical mixing unit 3, the driving motor is started to drive the main shaft to rotate. The diversion grooves on the rotating blades guide the wastewater to form a vortex, and at the same time, the auxiliary blades on the auxiliary shaft are driven to rotate through the multi-stage transmission mechanism, further enhancing the mixing effect of the chemical agent and the wastewater.

[0036] Inside the precipitation unit 4, there is a guide plate 10. The guide plate 10 has an arc-shaped structure. The radius of curvature of the arc-shaped plate is 500 mm to 800 mm. Multiple drainage holes 11 are provided on the inner side of the arc-shaped plate. The diameter of the drainage holes 11 is 10 mm to 20 mm, and the spacing of the drainage holes 11 is 50 mm to 100 mm. The mixed wastewater flows from the chemical mixing unit 3 into the precipitation unit 4. The arc-shaped structure of the guide plate 10 and the drainage holes 11 are used to divert the wastewater. The suspended matter in the wastewater settles under the action of gravity, and the clear water is discharged from the water outlet of the precipitation unit 4. The design of the arc-shaped structure can effectively disperse the flow direction of the wastewater and avoid the water flow directly impacting the precipitation area, while the design of the drainage holes 11 can further refine the wastewater diversion process to ensure that the suspended matter in the wastewater can fully settle under the action of gravity.

[0037] The specific operation process of this device is as follows: First, introduce the aquaculture wastewater into the device through the inlet unit 1. Start the stepper motor to drive the adjusting plate 7 to move along the slide rail 6 to adjust the flow rate of the wastewater flowing into the solid-liquid separation unit 2. When the adjusting plate 7 moves to one side, the flow area of the wastewater increases and the flow rate decreases; when the adjusting plate 7 moves to the other side, the flow area of the wastewater decreases and the flow rate increases. After the wastewater enters the solid-liquid separation unit 2, it is filtered step by step through the multi-layer filtration component 8. Larger suspended solids are intercepted on the filter plate 9, and smaller particulate matters flow with the wastewater to the chemical mixing unit 3. After the wastewater enters the chemical mixing unit 3, start the drive motor to drive the mixing component to rotate. The diversion grooves on the rotating blades guide the wastewater to form a vortex, and at the same time drive the secondary blades to rotate through the multi-stage transmission mechanism to enhance the mixing effect of the chemicals. The mixed wastewater enters the sedimentation unit 4, and the wastewater is shunted through the arc structure and drainage holes 11 of the diversion plate 10. The suspended solids in the wastewater settle under the action of gravity, and the clear water is discharged from the outlet of the sedimentation unit 4. Regularly clean the filter plate 9 in the solid-liquid separation unit 2 and the sediment in the sedimentation unit 4 to keep the device running normally.

[0038] The specific application scenario of this device is the wastewater treatment system of large-scale livestock farms. For example, in a pig farm with an annual output of 1000 live pigs, the daily wastewater production is about 50 tons. After the wastewater enters the device through the inlet unit 1, the adjusting plate 7 automatically adjusts the flow rate according to the change of the wastewater flow rate to ensure that the wastewater enters the solid-liquid separation unit 2 at an appropriate speed. The multi-layer filtration component 8 in the solid-liquid separation unit 2 can effectively remove the suspended solids in the wastewater. The step-by-step filtration design of the filter plate 9 significantly improves the removal efficiency of the suspended solids. After the wastewater enters the chemical mixing unit 3, through the action of the mixing component and the multi-stage transmission mechanism, the chemicals can be quickly and evenly dispersed in the wastewater, thereby improving the working efficiency of the subsequent treatment unit. The diversion plate 10 and drainage holes 11 in the sedimentation unit 4 can effectively disperse the flow direction of the wastewater, avoid the water flow directly impacting the sedimentation area, and ensure that the suspended solids in the wastewater can fully settle under the action of gravity. The treated clear water can be directly used for flushing or irrigation in the farm, realizing the resource utilization of the wastewater.

[0039] The connection and positional relationships between the components of this device are clear, and each component cooperates with each other to achieve efficient wastewater treatment. The support frame 5 provides stable support for the entire device, and the cooperation between the slide rail 6 and the adjustment plate 7 enables precise control of the wastewater flow rate. The multi-layer filtration assembly 8 in the solid-liquid separation unit 2 is fixed to the bracket through a card slot, facilitating disassembly and cleaning. The stirring assembly and the multi-stage transmission mechanism in the chemical agent mixing unit 3 are connected through gear meshing and transmission shafts, ensuring sufficient mixing of the chemical agent and the wastewater. The flow guide plate 10 in the precipitation unit 4 is fixed to the inner wall of the precipitation unit 4 by bolts, and the design of the drainage holes 11 further optimizes the wastewater diversion process. The pipeline connections between the units ensure smooth wastewater flow, and the structure of the entire device is compact and operates stably.

[0040] In order to better enable relevant personnel in the technical field to fully understand and implement the present invention, the specific implementation principles of the present invention are further supplemented below in combination with a specific application scenario.

[0041] In a large-scale livestock farm, the operation process of the wastewater treatment device is as follows: First, the breeding wastewater is introduced into the device through the inlet unit 1. At this time, the stepping motor is started, and the output shaft of the stepping motor drives the lead screw to rotate through a coupling. The lead screw is threadedly connected to the adjustment plate 7, causing the adjustment plate 7 to move along the slide rail 6. When the adjustment plate 7 moves to one side, the flow area of the wastewater increases and the flow rate decreases; when the adjustment plate 7 moves to the other side, the flow area of the wastewater decreases and the flow rate increases. This adjustment method can automatically adjust the flow rate according to the change in wastewater flow, ensuring that the wastewater enters the solid-liquid separation unit 2 at an appropriate speed. Through the cooperation between the adjustment plate 7 and the slide rail 6, precise control of the wastewater flow rate is achieved, avoiding a decline in treatment effect caused by too fast or too slow flow rate.

[0042] After the wastewater enters the solid-liquid separation unit 2, it is filtered step by step through the multi-layer filtration assembly 8. The filter plates 9 in the multi-layer filtration assembly 8 are arranged obliquely, with an inclination angle of 15° to 30°, and the pore diameters of the filter holes are 5 mm, 3 mm, and 1 mm from top to bottom in sequence. Larger suspended solids are intercepted on the filter plate 9 and slide down along the inclined surface of the filter plate 9 to the collection area under the action of gravity. Smaller particulate matters flow with the wastewater to the chemical agent mixing unit 3. This step-by-step filtration design can effectively improve the removal efficiency of suspended solids. At the same time, the filter plate 9 is fixed to the bracket through a card slot, facilitating disassembly and cleaning, and reducing the maintenance cost.

[0043] After the wastewater enters the chemical mixing unit 3, the driving motor is started, and the output shaft of the driving motor drives the main shaft to rotate through a coupling. The rotating blades on the main shaft are provided with diversion grooves, and the width of the diversion grooves is 2 mm to 5 mm, guiding the wastewater to form a vortex. At the same time, the first gear in the multi-stage transmission mechanism meshes with the second gear, the second gear is connected to the third gear through a transmission shaft, the third gear meshes with the fourth gear, the fourth gear is fixedly installed on the auxiliary shaft, and the auxiliary blades on the auxiliary shaft rotate accordingly. The synergistic effect of the rotating blades and the auxiliary blades enhances the mixing effect of the wastewater and the chemical agent, enabling the chemical agent to be quickly and evenly dispersed in the wastewater. This design significantly improves the utilization efficiency of the chemical agent, thereby enhancing the working efficiency of the subsequent treatment unit.

[0044] The mixed wastewater flows into the sedimentation unit 4, and the wastewater is shunted through the arc structure and drainage holes 11 of the guide plate 10. The guide plate 10 has an arc structure, and its radius of curvature is 500 mm to 800 mm. The arc structure can effectively disperse the flow direction of the wastewater and prevent the water flow from directly impacting the sedimentation area. The diameter of the drainage holes 11 is 10 mm to 20 mm, and the spacing is 50 mm to 100 mm, further refining the shunting process of the wastewater. The suspended solids in the wastewater settle under the action of gravity, and the clear water is discharged from the water outlet of the sedimentation unit 4. This design ensures that the suspended solids in the wastewater can fully settle under the action of gravity, reducing the content of suspended solids in the effluent.

[0045] During the actual operation process, the filter plate 9 in the solid-liquid separation unit 2 and the sediment in the sedimentation unit 4 are regularly cleaned to maintain the normal operation of the device. The filter plate 9 is fixed to the bracket through a card slot, which is convenient for disassembly and cleaning; the guide plate 10 in the sedimentation unit 4 is fixed to the inner wall through bolts, which is convenient for maintenance and replacement. The pipeline connections between the units ensure the smooth flow of the wastewater, and the structure of the whole device is compact and operates stably.

[0046] By implementing the above steps, this device can effectively solve the problems of low removal efficiency of suspended solids, uneven wastewater flow rate, and uneven chemical agent distribution in the prior art. The support frame 5 provides stable support for the whole device, and the cooperation of the slide rail 6 and the adjusting plate 7 realizes the precise control of the wastewater flow rate; the multi-layer filter assembly 8 in the solid-liquid separation unit 2 significantly improves the removal efficiency of suspended solids through a step-by-step filtration design; the stirring assembly and the multi-stage transmission mechanism in the chemical mixing unit 3 enhance the mixing effect of the chemical agent through synergistic action; the guide plate 10 and the drainage holes 11 in the sedimentation unit 4 optimize the shunting process of the wastewater, ensuring that the suspended solids can fully settle. The design of the whole device is reasonable, and each component cooperates with each other to achieve the efficient treatment and resource utilization of the wastewater.
