Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and specifically to a device for separating and treating bottom sludge in aquaculture ponds. Background Art

[0002] During the process of aquaculture, with the increase of the aquaculture time, a large amount of sludge will accumulate at the bottom of the pond. This sludge contains a large amount of organic matters such as uneaten bait, feces, and dead plankton that have not been completely decomposed. At the same time, there may also be various harmful microorganisms and heavy metal pollutants. The long-term accumulation of sludge will not only lead to eutrophication of the water body, affect the water quality, but also easily breed pathogens such as bacteria and viruses, increasing the risk of diseases of aquaculture animals, and seriously affecting the yield and quality of aquaculture.

[0003] Currently, for the treatment of bottom sludge in aquaculture ponds, most methods use manual dredging or simple mechanical dredging. Manual dredging has low efficiency, high labor intensity, and it is difficult to completely remove the sludge. While simple mechanical dredging equipment, although it improves the dredging efficiency to a certain extent, usually only pumps out the sludge from the bottom of the pond without effectively separating and treating the sludge. The pumped-out sludge contains a large amount of water and impurities, which is difficult to treat later, has a high cost, and is prone to secondary pollution. Therefore, there is an urgent need to design a device that can efficiently and thoroughly separate and treat the bottom sludge in aquaculture ponds.

[0004] In the prior art, such as Chinese Patent Publication No.: CN118807304A, a sludge separation device for sewage treatment in water conservancy projects is disclosed, including a treatment cylinder for collecting the separated sewage, and a water inlet pipe provided at the top of the treatment cylinder. A first material taking door is arranged on the outer side of the treatment cylinder, and a drain pipe is communicated with the bottom of the treatment cylinder; a base, a support frame is fixedly connected to the top of the base; a separation device for separating sewage and sludge; the outer side of the water inlet pipe is fixedly connected to the top of the treatment cylinder through a fixing frame, the bottom of the water inlet pipe penetrates through the top of the treatment cylinder, the bottom of the water inlet pipe is communicated with the top of the separation device and is rotatably connected to the top of the separation device through a sealing bearing. The present invention relates to the technical field of sewage treatment. This sludge separation device for sewage treatment in water conservancy projects can further squeeze out the water in the sludge and improve the separation efficiency.

[0005] In the prior art, for the treatment of the bottom sludge in aquaculture ponds, most methods adopt manual dredging or simple mechanical dredging. Manual dredging has low efficiency, high labor intensity, and it is difficult to completely remove the sludge. For simple mechanical dredging equipment, although the dredging efficiency is improved to a certain extent, it usually only pumps the sludge out from the bottom of the pond without effectively separating the sludge. The pumped sludge contains a large amount of water and impurities, resulting in high subsequent treatment difficulty and cost, and it is also prone to secondary pollution. Therefore, there is an urgent need to design a device that can efficiently and thoroughly separate and treat the bottom sludge in aquaculture ponds.

[0006] Therefore, we propose a bottom sludge separation and treatment device for aquaculture to solve the problems raised in the above background technology. Summary of the Invention

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Example 1, please refer to Figures 1 - 8 As shown, the present invention provides a technical solution: a device for separating and treating pond bottom sludge based on aquaculture, including a support mechanism 1, and two longitudinally arranged bracket assemblies 1011 are fixedly connected in a linear array on the top end surface of the support mechanism 1; The inner side of the support frame assembly 1011 is rotatably connected with a support frame 4. The inner side of the support frame 4 is fixedly connected with a side plate assembly 4012. There are two side plate assemblies 4012 in total. The two side plate assemblies 4012 are fixedly connected to the left and right sides inside the support frame 4 in an opposite direction. Three guiding slots 4014 are arranged in an arc array inside each of the two side plate assemblies 4012. The side plate assembly 4012 has magnetism and is an electromagnetic structure. A liquid seepage mechanism 5 is installed on the outer side of each of the two side plate assemblies 4012. The main body of the liquid seepage mechanism 5 is an arc structure, and there are two liquid seepage mechanisms 5 in total. The two liquid seepage mechanisms 5 are arranged in an opposite direction. Liquid seepage holes 501 are arranged in an arc array inside each of the two liquid seepage mechanisms 5. On the side of the liquid seepage mechanism 5 facing the side plate assembly 4012, there is also fixedly connected an insertion block assembly 5011. There are six insertion block assemblies 5011 in total. Among them, every three insertion block assemblies 5011 arranged in an annular array form a group. The two groups of insertion block assemblies 5011 are fixedly connected to the inner sides of the two liquid seepage mechanisms 5 in an opposite direction. And a limiting block 5012 is fixedly connected to the outer side of each of the two groups of insertion block assemblies 5011. The limiting block 5012 protrudes from the insertion block assembly 5011. The limiting block 5012 and the insertion block assembly 5011 together form a limiting assembly with a T-shaped structure, which matches the guiding slot 4014 opened in the side plate assembly 4012.

[0025] In this embodiment, during use, the device is fixed to the dredging area at the bottom of the aquaculture pond through the mounting holes 101 at the four corners of the support mechanism 1. On the side plate mechanism 2 on the outer side of the left support frame assembly 1011, the output shaft of the servo motor A201 passes through the side plate mechanism 2 through a bearing seat. The bevel gear of the transmission assembly A2011 at its top meshes with the bevel gear of the transmission assembly B4011 on the outer side of the feed pipe 401 to form a transmission connection. At this time, the side plate assembly 4012 is not powered on. The liquid seepage mechanism 5 inserts the T-shaped limiting block 5012 of the insertion block assembly 5011 into the guiding slot 4014 of the side plate assembly 4012, but is not magnetically adsorbed and is in an initial state where it can slide along the slot. Feeding and rotary pretreatment: The silt enters the inside of the support frame 4 through the feeding port on the left side of the feed pipe 401. The servo motor A201 is started, and the support frame 4 is driven to rotate around the support frame assembly 1011 through the transmission assembly A2011 and the transmission assembly B4011, so that the silt is preliminarily dispersed under the action of centrifugal force and the impurities are preliminarily separated. Spiral extrusion and liquid seepage: The servo motor C4015 on the right side of the support frame 4 is started to drive the spiral assembly 4016 to rotate. The spiral assembly 4016 forms a spiral propulsion force between the support frame 4 and the inner side of the liquid seepage mechanism 5, squeezing the sludge towards the right discharge pipe 4013. At this time, the side plate assembly 4012 is electrified to generate magnetism, adsorbing the liquid seepage mechanism 5 to make it closely adhere to the outer side of the support frame 4. The liquid seepage holes assembly 501 in the liquid seepage mechanism 5 forms a filtration channel. During the extrusion process, water is discharged through the liquid seepage holes, completing the preliminary solid-liquid separation. The separated liquid is discharged through the gap between the liquid seepage mechanism 5 and the support frame 4, and the solid sludge moves towards the discharge pipe 4013; It solves the problem that the existing equipment can only simply pump out sludge and lacks a solid-liquid separation link, resulting in great difficulty in subsequent treatment. Through the extrusion of the spiral assembly 4016 and the filtration of the liquid seepage mechanism 5, the preliminary separation of water in the sludge is realized, reducing the subsequent treatment volume; the rotation pretreatment of the support frame 4 makes the sludge more evenly dispersed, improving the separation efficiency.

[0026] Embodiment 2, as Figures 1 - 5 shown, the side plate assembly 4012 is in the state of being electrified to generate magnetism, the liquid seepage mechanism 5 is in the state of being magnetically adsorbed and limited to the outer side of the support frame 4, and there are installation holes 101 opened inside the support mechanism 1. There are four installation holes 101 in total, and the four installation holes 101 are respectively opened at the four corner positions inside the support mechanism 1. And a guide pipe 1012 with an L-shaped structure is fixedly connected to the inner side of the bracket assembly 1011 on the right side. The right opening of the guide pipe 1012 is for discharging materials. The top of the longitudinal member in the guide pipe 1012 is fixedly connected with a collecting hopper 1013. The main body of the collecting hopper 1013 is a frustum-shaped structure with a wider top and a narrower bottom. And the collecting hopper 1013 communicates with the guide pipe 1012 and together forms a feeding structure for the sludge. A servo motor C4015 is installed on the right side of the support frame 4. The left side of the servo motor C4015 is provided with an output shaft, and a spiral assembly 4016 is installed on this output shaft through a coupling. The spiral assembly 4016 is located inside the support frame 4 and two liquid seepage mechanisms 5. And the servo motor C4015 and the spiral assembly 4016 together form a spiral feeding and liquid discharging structure.

[0027] In this embodiment, during use, the side plate assembly 4012 is continuously electrified, and the liquid seepage mechanism 5 remains in the adsorbed state to ensure the sealing performance during the extrusion process. The spiral assembly 4016 pushes the preliminarily separated solid sludge to the discharge pipe 4013 of the right side plate assembly 4012, and enters the guide pipe 1012 through the circular tubular discharge pipe 4013; The sludge discharged from the discharge pipe 4013 falls into the hopper 1013 with a frustum-shaped structure that is thick at the top and thin at the bottom. Utilizing gravity, it slides down rapidly and is discharged through the right-side opening of the L-shaped material guiding pipe 1012 to subsequent treatment devices such as sludge dewatering equipment or a temporary storage tank. During this process, the longitudinal member of the material guiding pipe 1012 and the hopper 1013 form a continuous feeding channel to prevent the sludge from staying. It solves the problem that the discharge of traditional equipment is prone to blockage and lacks a design for the directional transportation of the separated sludge. The liquid leakage mechanism 5 fixed by magnetic attraction ensures no leakage during the extrusion process, enhancing the separation reliability; the combination of the hopper 1013 and the material guiding pipe 1012 realizes the efficient and directional transportation of the sludge, avoiding blockage and improving the overall treatment efficiency.

[0028] Example three, as Figures 6 - 8 shown, on the left end face of the bracket assembly 1011 located on the left, a side plate mechanism 2 is fixedly connected. The side plate mechanism 2 is perpendicularly arranged with the bracket assembly 1011, and a servo motor A201 is installed on the bottom end face of the side plate mechanism 2. The top of the servo motor A201 is provided with an output shaft, which passes upward through the side plate mechanism 2 and is connected to the side plate mechanism 2 through a bearing seat. A transmission assembly A2011 is installed on the top output shaft of the servo motor A201. On the left side of the support frame 4, a feed pipe 401 is fixedly connected. The feed pipe 401 is in communication with the support frame 4, and a feed port is opened on the left side of the feed pipe 401. A transmission assembly B4011 is fixedly connected to the outside of the feed pipe 401. The transmission assembly B4011 is meshed and driven with the transmission assembly A2011, and both the transmission assembly B4011 and the transmission assembly A2011 are bevel gear structures. On the right side of the side plate assembly 4012 located on the right, a discharge pipe 4013 is fixedly connected. The main body of the discharge pipe 4013 is a circular tubular structure, and the discharge pipe 4013 is in communication with the support frame 4 through the side plate assembly 4012. A guide frame assembly 2012 is fixedly connected to the outside of the bracket assembly 1011. There are a total of four guide frame assemblies 2012. Among them, every two longitudinally adjacent guide frame assemblies 2012 form a group, and the two groups of guide frame assemblies 2012 are fixedly connected in a linear array on the front and rear side surfaces of the two bracket assemblies 1011. The top of both groups of guide frame assemblies 2012 is provided with a notch, and a guide wheel 2013 is rotatably connected inside the notch. On the right side of one of the groups of guide frame assemblies 2012 located on the right, a horizontally arranged connecting mechanism 3 is further fixedly connected. A bracket assembly 301 is fixedly connected to the right side of the connecting mechanism 3. A servo motor B3011 is installed at the front end of the bracket assembly 301. A driving wheel 3012 is installed on the rear output shaft of the servo motor B3011. The driving wheel 3012 and the guide wheel 2013 are respectively used to drive and guide the liquid leakage mechanism 5.

[0029] In this embodiment, during use, before the device runs, the side plate mechanism 2 located outside the left support assembly 1011 and the right support assembly 1011 form a symmetric support structure through the guide frame assembly 2012. On the front and rear sides of the right support assembly 1011, two groups of guide frame assemblies 2012 are fixedly connected respectively. Each group consists of two longitudinally adjacent guide frame assemblies 2012. A guide wheel 2013 is rotatably connected in the notch at the top of each group of guide frame assemblies 2012. The guide wheel 2013 is made of wear-resistant rubber material, and an annular groove matching the convex rib on the outside of the liquid seepage mechanism 5 is provided on the surface to enhance the guiding stability. The right side of a group of guide frame assemblies 2012 on the right is fixedly connected to the bracket assembly 301 through the transverse connection mechanism 3. The servo motor B3011 at the front end of the bracket assembly 301 is connected to the driving wheel 3012 through a coupling; At this time, the liquid seepage mechanism 5 is completely inserted into the guiding slot 4014 of the side plate assembly 4012 through the T-shaped limiting block 5012 of the plug block assembly 5011. The side plate assembly 4012 is in an energized state, and magnetic adsorption makes the liquid seepage mechanism 5 closely fit against the outside of the support frame 4. The liquid seepage hole assembly 501 remains in an open state, and the device is in a normal separation operation mode; When the device continuously runs for a preset time, such as 2 hours, or it is detected by the pressure sensor (which can be integrated on the inside of the side plate assembly 4012 or the liquid seepage mechanism 5) that the pressure difference across the liquid seepage hole assembly 501 exceeds the threshold, indicating that the liquid seepage hole is blocked, resulting in an increase in the liquid flow resistance, the control system issues an instruction; The first step: The servo motor C4015 pauses running, and the spiral assembly 4016 stops rotating to prevent sludge from continuing to enter the treatment chamber during the cleaning process; The second step: The side plate assembly 4012 is de-energized and demagnetized. The disappearance of the magnetic field releases the adsorption force between the liquid seepage mechanism 5 and the side plate assembly 4012. However, the T-shaped fit between the limiting block 5012 and the guiding slot 4014 still restricts the lateral detachment of the liquid seepage mechanism 5, only allowing it to slide longitudinally along the slot; The third step: The servo motor B3011 starts, and the driving wheel 3012 rotates clockwise. Through the gear-rack transmission, the liquid seepage mechanism 5 is driven to move upward along the guide frame assembly 2012. The guide wheel 2013 rolls synchronously in the notch, providing a longitudinal guiding force for the liquid seepage mechanism 5 to ensure that its moving trajectory is consistent with the axial direction of the guiding slot 4014, avoiding jamming of the plug block assembly 5011 and the slot due to deviation. When the liquid seepage mechanism 5 moves upward to the extreme position at the top of the guide frame assembly 2012, its plug block assembly 5011 completely disengages from the guiding slot 4014 of the side plate assembly 4012. At this time, the liquid seepage mechanism 5 is in a suspended state, exposed to the outside of the support frame 4, facilitating comprehensive cleaning. The cleaning process adopts the "air-water combined backwashing" mode: The degree of plugging of the infiltration holes is monitored in real time through a pressure sensor, and combined with the preset operation time, the automatic triggering and process control of the cleaning operation are realized, without manual intervention, reducing the risk of operation errors, and at the same time avoiding energy waste caused by excessive cleaning. The cleaning system is applicable to sludge separation scenarios with different particle sizes - for sludge with a higher sand content, the gas backwashing pressure and the brush rotation speed can be increased; for sludge rich in organic matter, the washing water temperature and the ratio of chemical cleaning agents such as protease can be adjusted. By replacing modular components such as the infiltration hole components 501 with different pore sizes, the equipment can adapt to a variety of water quality conditions. The filter components of traditional sludge separation equipment generally adopt a fixed installation mode. During cleaning, the machine needs to be stopped and disassembled manually, and the single maintenance takes up to 2 - 4 hours. Moreover, frequent disassembly is likely to cause wear of the seals, affecting the reliability of the equipment. In this embodiment, through the combination of the magnetic adsorption type movable liquid seepage mechanism 5 and the automatic cleaning system, the single cleaning cycle is shortened to 5 - 8 minutes, and there is no need for manual contact with the contaminated components throughout the process, reducing the health risks of the operators. In addition, the transmission system of the guide wheel 2013 and the driving wheel 3012 adopts a fully enclosed lubrication design and lubricating grease is regularly filled through a grease nipple, which is a conventional maintenance method for mechanical transmission, and its service life can reach more than 8000 hours. Compared with the traditional open gear transmission, the maintenance frequency is reduced by 75%, further ensuring the continuous operation ability of the equipment. To solve the problems that after the filter components of the existing equipment are blocked, they need to be disassembled and cleaned manually, resulting in interrupted processing and low efficiency, and the traditional mechanical connection method is likely to cause component loss and affect the stability of the equipment. Through the innovative combination of electromagnetic adsorption and automatic transmission, the rapid separation, efficient cleaning and precise reset of the liquid seepage mechanism 5 are realized, the cleaning time is compressed to less than 1 / 10 of the traditional process, and at the same time, the equipment damage caused by manual operation is avoided, the comprehensive processing efficiency of the equipment is increased by more than 40%, and the operation reliability is increased to more than 99.5%, significantly reducing the operation and maintenance costs of aquaculture enterprises.
