Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology of wastewater, and in particular to a solid-liquid separation mechanism for aquaculture wastewater. Background Technology

[0002] Solid-liquid separation equipment for livestock and aquaculture wastewater is a device or system that separates solid substances from liquid components in wastewater generated during the breeding process of livestock, poultry, and aquaculture through physical, mechanical, or physicochemical processes. This type of equipment is a key link in the pretreatment of livestock and aquaculture wastewater, and its design and operation directly affect the subsequent wastewater treatment effect and the resource utilization efficiency of solid waste.

[0003] However, in the existing technology, for livestock and poultry farming wastewater containing large amounts of coarse fiber or sticky substances such as pig manure and chicken manure, traditional solid-liquid separation processes mainly use mechanical filtration equipment such as vibrating screens and rotary drum screens, as well as gravity sedimentation equipment such as sedimentation tanks. However, the existing technology has significant drawbacks. For mechanical filtration equipment, coarse fiber in pig manure and sticky organic matter in chicken manure adhere and accumulate on the screen surface, causing rapid blockage of the screen pores. This results in low separation efficiency, frequent equipment maintenance, and high subsequent treatment load when solid-liquid separation equipment is used to treat high-fiber and high-viscosity livestock wastewater. There is an urgent need to improve its applicability and treatment effect through structural improvements. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a solid-liquid separation mechanism for aquaculture wastewater.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a solid-liquid separation mechanism for aquaculture wastewater, comprising a solid collection mechanism, a wastewater discharge mechanism fixedly connected to one side of the solid collection mechanism, two filter plates installed inside the wastewater discharge mechanism, the filter plates being located at the junction of the solid collection mechanism and the wastewater discharge mechanism, a cleaning mechanism installed between the two filter plates, the cleaning mechanism comprising a first slide rail and a mounting frame, the first slide rail being fixedly connected to the inside of the discharge tank, and a first slider being slidably connected inside the first slide rail, a first servo motor being fixedly connected to the upper part of the first slide rail, a lead screw being fixedly connected to the output end of the first servo motor, the lead screw being threadedly connected to the first slider, the mounting frame being fixedly connected to the side of the first slider, and a roller brush being rotatably connected to the side of the mounting frame, a drive assembly being installed at the end of the roller brush, and the drive assembly being fixedly connected to the mounting frame.

[0006] Preferably, the solid collection mechanism includes a collection box with a funnel-shaped bottom, and a drain pipe is fixedly connected to the bottom of the collection box, with a valve installed on the surface of the drain pipe.

[0007] Preferably, the wastewater discharge mechanism includes a discharge tank, and a discharge pipe is fixedly connected to the side of the discharge tank.

[0008] Preferably, the drive assembly includes a second servo motor, a second synchronous pulley, and a synchronous belt. The second servo motor is fixedly connected to the mounting frame, and the output end of the second servo motor is fixedly connected to a first synchronous pulley. The second synchronous pulley is rotatably connected to the mounting frame. The synchronous belt is movably connected to both the first and second synchronous pulleys. The end of the second synchronous pulley is fixedly connected to the roller brush.

[0009] Preferably, a second slide rail is fixedly connected to the inner wall of the drain tank, and a second slider is slidably connected inside the second slide rail. The second slider is rotatably connected to the roller brush.

[0010] Preferably, a spray pipe is fixedly connected to the bottom of the mounting frame, a spray nozzle is fixedly connected to the side of the spray pipe, and a water supply device is connected to the outside of the spray pipe.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the solid collection mechanism realizes the centralized collection and convenient discharge of solid precipitates, avoiding sedimentation and blockage. The wastewater discharge mechanism ensures the smooth discharge of filtered wastewater. The key lies in the setting of the cleaning mechanism. The first servo motor drives the lead screw to move the first slider back and forth on the first slide rail, so that the roller brush on the mounting frame moves laterally along the surface of the filter plate. At the same time, the second servo motor drives the roller brush to rotate at high speed through the first synchronous wheel, the synchronous belt, and the second synchronous wheel. With the water flow from the spray pipe and the nozzle, the coarse fibers and sticky substances on the surface of the filter plate are dynamically brushed and washed, effectively preventing the filter plate pores from being blocked by the deposited material, thereby improving the solid-liquid separation efficiency.

[0013] 2. In this invention, a first servo motor drives a lead screw to move a first slider up and down along a first slide rail, causing the roller brush and spray head on the mounting frame to move synchronously, achieving full-area cleaning of the filter plate. A second servo motor drives the roller brush to rotate at high speed via a first synchronous pulley, a synchronous belt, and a second synchronous pulley. This, combined with the high-pressure water flow from the spray pipe and spray head, creates a synergistic effect of mechanical brushing and hydraulic rinsing, effectively removing coarse fibers and sticky substances from the filter plate surface. The limiting structure of the second slide rail and the second slider ensures the stability of the roller brush and spray pipe movement, preventing uneven cleaning caused by vibration. This solution, through an automated and comprehensive cleaning mechanism, significantly reduces the frequency of filter plate clogging, extends equipment maintenance cycles, reduces subsequent processing load, and significantly improves the solid-liquid separation efficiency and equipment applicability for high-fiber, high-viscosity aquaculture wastewater.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4As shown, this utility model provides a solid-liquid separation mechanism for aquaculture wastewater, including a solid collection mechanism 1. A wastewater discharge mechanism 2 is fixedly connected to one side of the solid collection mechanism 1. Two filter plates 3 are installed inside the wastewater discharge mechanism 2. The filter plates 3 are located at the junction of the solid collection mechanism 1 and the wastewater discharge mechanism 2. A cleaning mechanism 4 is installed between the two filter plates 3. The cleaning mechanism 4 includes a first slide rail 41 and a mounting bracket 45. The first slide rail 41 is fixedly connected to the inside of the discharge tank 21, and a first slider 42 is slidably connected inside the first slide rail 41. A first servo motor 43 is fixedly connected to the upper part of the first slide rail 41. The output end of the servo motor 43 is fixedly connected to a lead screw 44, which is threadedly connected to the first slider 42. The mounting bracket 45 is fixedly connected to the side of the first slider 42, and a roller brush 410 is rotatably connected to the side of the mounting bracket 45. A drive assembly is installed at the end of the roller brush 410, and the drive assembly is fixedly connected to the mounting bracket 45. The solid collection mechanism 1 includes a collection box 11, the bottom of which is funnel-shaped, and a drain pipe 12 is fixedly connected to the bottom of the collection box 11. A valve 13 is installed on the surface of the drain pipe 12. The wastewater discharge mechanism 2 includes a drain tank 21, and a drain pipe 22 is fixedly connected to the side of the drain tank 21.

[0022] The specific settings and functions of this embodiment are described below. The aquaculture wastewater is fed into the collection tank 11 and filtered through the filter plate 3. During this process, solid sediments enter and exit the collection tank 11 and settle. At the same time, the filter plate 3 filters the solid waste in the aquaculture wastewater. After sedimentation and filtration, the aquaculture wastewater enters the discharge tank 21 through the filter plate 3 and is discharged into the next treatment stage through the discharge pipe 22.

[0023] The second servo motor 46 drives the first synchronous pulley 47 to rotate, which in turn drives the synchronous belt 48 and the second synchronous pulley 49 to rotate, thereby driving the roller brush 410 to brush the filter plate 3 to prevent the filter plate 3 from being blocked. At the same time, the filter plate 3 is rinsed by the spray pipe 411 and the nozzle 412 through the external water supply equipment.

[0024] Solid collection mechanism 1 enables centralized collection and convenient discharge of solid sediments, preventing clogging. Wastewater discharge mechanism 2 ensures smooth discharge of filtered wastewater. The key lies in the cleaning mechanism 4. Servo motor 43 drives screw 44 to move slider 42 back and forth on slide rail 41, causing roller brush 410 on mounting frame 45 to move laterally along the surface of filter plate 3. Simultaneously, servo motor 46 drives roller brush 410 to rotate at high speed via synchronous pulley 47, synchronous belt 48, and synchronous pulley 49. Combined with water flow from spray pipe 411 and nozzle 412, this dynamically washes and flushes coarse fibers and viscous substances from the surface of filter plate 3, effectively preventing clogging of the filter plate 3 pores by deposited substances. This improves solid-liquid separation efficiency, reduces equipment maintenance frequency, lowers subsequent treatment load, and significantly enhances applicability to high-fiber, high-viscosity aquaculture wastewater. This innovative structural design effectively solves the problem of low efficiency in traditional solid-liquid separation equipment when treating high-fiber, high-viscosity aquaculture wastewater.

[0025] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, the drive assembly includes a second servo motor 46, a second synchronous pulley 49, and a synchronous belt 48. The second servo motor 46 is fixedly connected to the mounting bracket 45, and the output end of the second servo motor 46 is fixedly connected to a first synchronous pulley 47. The second synchronous pulley 49 is rotatably connected to the mounting bracket 45. The synchronous belt 48 is movably connected to both the first synchronous pulley 47 and the second synchronous pulley 49. The end of the second synchronous pulley 49 is fixedly connected to a roller brush 410. A second slide rail 413 is fixedly connected to the inner wall of the drain tank 21. A second slider 414 is slidably connected inside the second slide rail 413. The second slider 414 is rotatably connected to the roller brush 410. A spray pipe 411 is fixedly connected to the bottom of the mounting bracket 45. A spray nozzle 412 is fixedly connected to the side of the spray pipe 411. A water supply device is connected to the outside of the spray pipe 411.

[0026] The overall effect of this embodiment is that the first servo motor 43 drives the lead screw 44 to rotate, thereby driving the first slider 42 to move up and down along the first slide rail 41, thereby driving the roller brush 410 and the spray head 412 up and down to thoroughly brush and rinse the filter plate 3. The second slider 414 slides along the second slide rail 413 to limit the up and down movement of the roller brush 410 and the spray pipe 411, thereby improving the stability of the roller brush 410 and the spray pipe 411 when they move up and down.

[0027] The system achieves efficient solid-liquid separation and automatic cleaning through multi-component collaboration, significantly improving the treatment effect of aquaculture wastewater. The solid collection mechanism 1 enables centralized sedimentation and convenient discharge of precipitates; the wastewater discharge mechanism 2 ensures smooth discharge of filtered wastewater. The core innovation lies in the cleaning mechanism 4: the first servo motor 43 drives the lead screw 44 to move the first slider 42 up and down along the first slide rail 41, so that the roller brush 410 and the spray head 412 on the mounting frame 45 move synchronously, achieving full-area coverage cleaning of the filter plate 3; the second servo motor 46 drives the roller brush 410 to rotate at high speed through the first synchronous wheel 47, the synchronous belt 48, and the second synchronous wheel 49, which, together with the high-pressure water flow of the spray pipe 411 and the spray head 412, forms a synergistic effect of mechanical brushing and hydraulic flushing, effectively removing coarse fibers and sticky substances from the surface of the filter plate 3. The limiting structure of the second slide rail 413 and the second slider 414 ensures the stability of the movement of the roller brush 410 and the spray pipe 411, and avoids uneven cleaning caused by shaking. This solution significantly reduces the clogging frequency of the filter plate 3 through an automated and all-round cleaning mechanism, extends the equipment maintenance cycle, reduces the subsequent treatment load, and significantly improves the solid-liquid separation efficiency and equipment applicability of high-fiber and high-viscosity aquaculture wastewater.

[0028] The method of use and working principle of this device: Aquaculture wastewater is introduced into the collection tank 11 and filtered through the filter plate 3. During this process, solid sediments enter and exit the collection tank 11 for sedimentation. At the same time, the filter plate 3 filters the solid waste in the aquaculture wastewater. After sedimentation and filtration, the aquaculture wastewater enters the discharge tank 21 through the filter plate 3 and is discharged into the next treatment stage through the discharge pipe 22.

[0029] The No. 2 servo motor 46 drives the No. 1 synchronous pulley 47 to rotate, which in turn drives the synchronous belt 48 and the No. 2 synchronous pulley 49 to rotate, thereby driving the roller brush 410 to brush the filter plate 3 to prevent the filter plate 3 from being blocked. At the same time, the filter plate 3 is rinsed by the spray pipe 411 and the nozzle 412 through the external water supply equipment.

[0030] The first servo motor 43 drives the lead screw 44 to rotate, thereby driving the first slider 42 to move up and down along the first slide rail 41, thereby driving the roller brush 410 and the spray head 412 up and down to thoroughly brush and rinse the filter plate 3. The second slider 414 slides along the second slide rail 413 to limit the up and down movement of the roller brush 410 and the spray pipe 411, thereby improving the stability of the roller brush 410 and the spray pipe 411 when moving up and down.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
