During the process of saline-alkali aquaculture, due to the influence of high salinity and alkaline environment, a large amount of sludge is easily generated. These sludges not only affect water quality and aquaculture effects, but may also cause environmental pollution. Therefore, it is crucial to reasonably treat saline-alkali aquaculture sludge.

The present invention drives the deceleration discharge mechanism to rotate by using the servo motor to perform slow discharge work, and before discharging, the servo motor can also drive the anti-clogging filtering mechanism to perform primary filtering work on the sludge in the saline-alkali aquaculture pond, improving the structural linkage of the discharge work and the primary filtering work, and improving the usage effect of the device for recycling and treating sludge in the saline-alkali aquaculture pond.

[0004] However, when the existing device for recycling and treating sludge in saline-alkali aquaculture ponds is in use, there are at least the following deficiencies: (1) The existing device drives the primary sieve frame to reciprocate up and down through a reciprocating lead screw for sludge filtration. For the gravel in high-concentration sludge, it cannot be effectively separated, resulting in a high impurity content in the dried sludge as fertilizer, affecting the fertilizer efficiency and soil quality; (2) By driving the transmission screw to rotate forward inside the fixed bearing seat when the third transmission rod rotates, driving the movable seat and the filter plate to move towards each other to squeeze and filter the sludge in the saline-alkali aquaculture pond after primary filtration, there is a problem that the moisture content of the dried sludge is still relatively high.

[0022] The following will describe the present invention in detail with reference to the accompanying drawings.

[0023] The following describes the present invention and its implementation manners, which is not restrictive, and the actual implementation manners are not It is limited to this. In short, if those of ordinary skill in the art are inspired by it and design similar structural forms and embodiments without departing from the purpose of the present invention without creative efforts, they shall fall within the protection scope of the present invention.

[0024] The inventor's research found that when the existing sludge recovery and treatment device for saline-alkali aquaculture ponds is in use, there are at least the following deficiencies: (1) The existing device drives the primary sieve frame to reciprocate up and down through a reciprocating lead screw for sludge filtration. For the gravel in high-concentration sludge, it cannot be effectively separated, resulting in a high impurity content in the subsequent dried sludge as fertilizer, affecting the fertilizer efficiency and soil quality; (2) When the third transmission rod rotates, it drives the transmission screw to rotate forward inside the fixed bearing seat, driving the movable seat and the filter plate to move towards each other to squeeze and filter the sludge of the saline-alkali aquaculture pond after primary filtration. There is a problem that the water content of the dried sludge is still relatively high.

[0025] Based on the above findings, the present application proposes a sludge recovery and treatment device for saline-alkali aquaculture ponds, including a feed barrel, a driving rod, a sludge treatment mechanism, and a filter barrel. The sludge treatment mechanism is arranged inside the feed barrel, and the driving rod drives the sludge treatment mechanism to separate and treat the sludge of the saline-alkali aquaculture pond; the filter barrel is communicated with the feed barrel and is used for filtering and collecting the sludge separated and treated by the sludge treatment mechanism. Through the combined use of the feed barrel, the driving rod, the sludge treatment mechanism, and the filtering mechanism in the present application, it is possible to effectively separate and treat impurities such as gravel in the sludge through the sludge treatment mechanism, and through the filtering mechanism, filter and collect the separated and treated sludge, and can efficiently filter and collect the sludge, thereby effectively avoiding the problems of high impurity content in the existing treated sludge and still relatively high water content of the dried sludge. Embodiment 1:

[0026] Refer to Figures 1 - 15 , this embodiment discloses a sludge recovery and treatment device for saline-alkali aquaculture ponds, including a feed barrel 1, a driving rod 2, a sludge treatment mechanism 3, and a filter barrel 4; Among them, The driving rod 2 passes through the first through hole 107 provided on the side of the feed barrel 1 and is connected to the sludge treatment mechanism 3; The sludge treatment mechanism 3 is arranged inside the feed barrel 1, and the driving rod 2 drives the sludge treatment mechanism 3 to separate and treat the sludge of the saline-alkali aquaculture pond; The filter barrel 4 is communicated with the feed barrel 1 and is used for filtering and collecting the sludge separated and treated by the sludge treatment mechanism 3.

[0027] In an embodiment of the present application, a device for recycling and treating sludge in a saline-alkali aquaculture pond includes a feed barrel 1, a driving rod 2, a sludge treatment mechanism 3, and a filtering barrel 4. During use, a certain amount of sludge from a saline-alkali aquaculture pond is put into the interior of the feed barrel. The sludge treatment mechanism 3 is arranged inside the feed barrel 1. By externally connecting a power source, such as a motor, to the outer side of the driving rod 2, the driving rod is driven by the externally connected power source, so that the sludge treatment mechanism connected to the driving rod is driven by the driving rod, realizing the separation treatment of the sludge inside the feed barrel by the sludge treatment mechanism. The filtering barrel 4 is communicated with the feed barrel 1. After the sludge is separated and treated by the sludge treatment mechanism 3, it flows into the filtering barrel, and the separated and treated sludge is filtered and collected inside the filtering barrel, thereby realizing the recycling and treatment of the sludge in the saline-alkali aquaculture pond, achieving the efficient recycling of the sludge, and reducing the discharge amount and treatment cost of the sludge. Through the coordinated use of the feed barrel, the driving rod 2, the sludge treatment mechanism 3, and the filtering mechanism 4 in the present application, the effective separation treatment of impurities such as gravel in the sludge can be realized by the sludge treatment mechanism 3, and the separated and treated sludge can be filtered and collected by the filtering mechanism, so that the sludge can be efficiently filtered and collected, thus effectively avoiding the problems of high impurity content in the treated sludge and still relatively high moisture content in the dried sludge existing in the prior art.

[0028] Specifically, referring to the attached Figure 3 figure, in an embodiment of the present application, the feed barrel 1 includes: A fixed cover 102; A movable cover 101. The fixed cover 102 and the movable cover 101 are arranged at the barrel opening of the feed barrel 1. The fixed cover 102 is fixedly connected to the feed barrel 1, and the fixed cover 102 and the movable cover 101 are movably connected. By opening the movable cover plate 101, the sludge from the saline-alkali aquaculture pond to be treated is placed in the feed barrel 1. Through the arrangement of the fixed cover 102 and the movable cover 101, it can be ensured that the sludge to be treated inside the feed barrel 1 is restricted within the feed barrel during the separation treatment process, providing a relatively closed and stable environment for the separation treatment of the sludge, ensuring the normal operation of the equipment and the safety of personnel, and reducing the possibility of accidents; A filter plate 103, arranged inside the cavity of the feed barrel 1, dividing the feed barrel 1 into an upper feed barrel 105 and a lower feed barrel 106; the upper feed barrel 105 is used for the sludge treatment mechanism 3 to separate and treat the sludge from the saline-alkali aquaculture pond, and the lower feed barrel 106 is used for the sludge from the saline-alkali aquaculture pond separated and treated by the sludge treatment mechanism 3 to flow into the filtering barrel 4; A second through hole 104, arranged on the upper feed barrel 105, for discharging the separated impurities; through the arrangement of the second through hole 104, when the separation treatment is carried out by the sludge treatment mechanism, impurities in the sludge, such as gravel, are discharged through the second through hole 104, while the sludge flows into the lower feed barrel 106 through the filter plate 103 and flows from the lower feed barrel 106 into the filtering mechanism 4 for subsequent filtering and collection operations; The first through hole 107 is provided on the side wall of the feeding barrel 1. The driving rod 2 passes through the first through hole 107 and is connected to the sludge treatment mechanism 3, and the sludge treatment mechanism 3 is driven by the driving rod 2 to separate the sludge in the saline-alkali land aquaculture pond.

[0029] As shown in the accompanying drawings, in the embodiment of the present application, the sludge treatment mechanism 3 is arranged above the filter plate 103 and is connected to the filter plate 103. By rotating the sludge treatment mechanism 3, the sludge in the saline-alkali land aquaculture pond can be separated, and the separated sludge flows into the blanking barrel 106 through the filter plate 103 for subsequent filtering and collection operations.

[0030] In the embodiment of the present application, a plurality of second through holes 104 are provided. By providing a plurality of second through holes, the crushed stones and the like separated and treated in the sludge can be discharged in time, avoiding the accumulation of the separated crushed stones in the feeding barrel.

[0031] In the embodiment of the present application, the blanking barrel 106 has a funnel-shaped structure, which is wider at the top and narrower at the bottom. When the sludge separated by the sludge treatment mechanism 3 flows into the blanking barrel 106 through the filter plate 103, under the action of its own weight, the sludge will gradually gather towards the outlet along the inclined surface of the funnel, facilitating the smooth entry of the sludge from the blanking barrel 106 into the filter barrel 4 for sludge filtering and collection operations, ensuring the smooth progress of the sludge treatment operation.

[0032] In the embodiment of the present application, through the settings of the filter plate 103 and the second through holes 104, when the sludge treatment mechanism 3 separates the sludge in the feeding barrel, the crushed stones in the sludge can be discharged outside the material distribution barrel 1 through the second through holes, which can greatly reduce the moisture content and impurity rate of the sludge. The separated sludge flows into the filter barrel 4 through the blanking barrel 106 for filtering and collection, thus avoiding the problems of high impurity content in the treated sludge and high moisture content of the dried sludge, which affect the fertilizer efficiency and soil quality when the treated sludge is used as fertilizer.

[0033] Based on the above technical solutions, as shown in Figures 4 - 7 the sludge treatment mechanism 3 includes: A rotating shaft 301, the rotating shaft 301 is connected to the filter plate 103, the upper end of the rotating shaft 301 is connected to the driving rod, and the rotation of the rotating shaft 301 is driven by the driving rod 2, so that the sludge treatment mechanism 3 performs centrifugal separation on the sludge in the saline-alkali land aquaculture pond to be treated; A sleeve 302, sleeved outside the rotating shaft 301; Fan blades 303 are arranged on the outer circumference of the rotating shaft 301. The fan blades 303 are driven by the rotating shaft 301 to rotate centrifugally to perform centrifugal stirring on the sludge, realizing the separation treatment of the sludge in the saline-alkali land aquaculture pond.

[0034] In the embodiment of the present application, by sleeving a sleeve 302 on the rotating shaft 301, and arranging the fan blade 303 on the outer periphery of the rotating shaft 301, the fan blade 303 is driven by the rotating shaft 301 to perform centrifugal rotation, so as to centrifugally stir the sludge, and realize the separation treatment of the sludge in the saline-alkali land aquaculture pond.

[0035] It should be noted that in the embodiment of the present application, the method of driving the fan blade 303 to perform centrifugal rotation by the rotating shaft to centrifugally stir the sludge and realize the separation treatment of the sludge in the saline-alkali land aquaculture pond has the following advantages: (1) The centrifugal rotation method can more quickly and effectively stratify the sludge according to density and particle size, and has a better separation effect on sludge components with different properties, which is beneficial to the subsequent targeted treatment of different layers of sludge. The reciprocating lifting method mainly performs solid-liquid separation through simple screening, and the stratification effect is relatively weak; (2) By adopting the centrifugal rotation method, the centrifugal force can provide a large driving force, so that the water and small particle substances in the sludge can pass through the filter medium more quickly, and the filtration efficiency is relatively high. In contrast, the reciprocating lifting method relies on extrusion and vibration to promote the liquid and small particles to pass through the sieve holes, and the speed is relatively slow; (3) The rotational movement of the fan blade can make the sludge continuously flow under the action of centrifugal force, reducing the accumulation and blockage of sludge particles on the filter medium. The sludge treatment mechanism 3 of the present application can efficiently separate and filter the sludge while being convenient to operate.

[0036] Specifically, as shown in the attached drawings, a first through groove 305 and a mounting seat 309 are provided on the rotating shaft 301, and an electric push rod 310 is arranged inside the rotating shaft 301; A second through groove 308 is provided on the sleeve 302, a connecting card slot 304 is arranged beside the second through groove 308, and a centripetal rod 311 is arranged on the inner wall of the sleeve 302; A connecting rod 306 and a connecting shaft 312 are provided on the fan blade 303; the centripetal rod 311 passes through the first through groove 305 and is connected to the electric push rod 310; The mounting seat 309 is located at the second through groove 308, the connecting shaft 312 is arranged inside the mounting seat 309, and a movable roller 307 is arranged at one end of the connecting rod 306, and the movable roller 307 is arranged to roll in the connecting card slot 304.

[0037] In the embodiment of the present application, a first through groove 305 and a mounting seat 309 are provided on the rotating shaft 301, and an electric push rod 310 is arranged inside the rotating shaft 301; a second through groove 308 is provided on the sleeve 302, a connecting card slot 304 is arranged beside the second through groove 308, and a centripetal rod 311 is arranged on the inner wall of the sleeve 302; a connecting rod 306 and a connecting shaft 312 are provided on the fan blade 303; and the centripetal rod 311 passes through the first through groove 305 and is connected to the electric push rod 310; the mounting seat 309 is located at the second through groove 308, the connecting shaft 312 is arranged inside the mounting seat 309, a movable roller 307 is arranged at one end of the connecting rod 306, and the movable roller 307 is rotatably arranged in the connecting card slot 304. When in use, an external power source, such as a motor, is externally connected to the outside of the driving rod 2, and the driving rod 2 is driven by the external power source, so that the rotating shaft 301 connected to the driving rod 2 is driven by the driving rod 2, and the rotating shaft 301 rotates to drive the sleeve 302 and the fan blade 303 sleeved thereon to rotate, thereby realizing centrifugal stirring of the sludge in the material separation bucket by the fan blade, separating the impurities in the sludge, and thus realizing the separation treatment of the sludge in the saline-alkali land aquaculture pond, and the operation is convenient.

[0038] It should be noted that, in the embodiment of the present application, the separation treatment of the sludge in the inner cavity of the material separation bucket can be realized by adjusting the driving force of the driving rod on the rotating shaft, and the angle of the fan blade 303 can be adjusted by the adjustment of the electric push rod, so that the centrifugal stirring and separation operations can be realized for sludges with different concentrations. For example, for sludges with high viscosity and high concentration, it is difficult to directly process. By adjusting the angle of the fan blade to a smaller angle through the electric push rod, the tangential rotating force is larger, so as to effectively separate the sludge. Specifically, when the electric push rod 310 moves, the centripetal rod 311 is driven by the electric push rod 310 to move in the first through groove 305, so that the movable roller 307 arranged at one end of the connecting rod 306 slides in the connecting card slot 304, changing the angle of the fan blade, realizing centrifugal stirring of sludges with different concentrations, and thus realizing the separation treatment of the sludge in the saline-alkali land aquaculture pond, and the operation is convenient.

[0039] Based on the above technical solutions, referring to Figures 9 - 12 , the filter bucket 401 includes an upper bucket, a middle bucket, and a lower bucket; an inner bucket 415 is arranged in the upper bucket, and there is a gap 416 between the upper bucket and the inner bucket 415 for collecting the impurities separated by the feeding bucket 1.

[0040] Referring to the attached drawings, in the embodiment of the present application, the blanking bucket 106 is sleeved in the inner bucket 415. When the driving rod 2 drives the sludge treatment mechanism 3 to separate the sludge in the saline-alkali land aquaculture pond, impurities such as gravel in the sludge will flow from the second through hole 104 into the gap 416 between the upper bucket and the inner bucket 401 for collection.

[0041] It should be noted that in the embodiment of the present application, a water inlet hole 414 is provided above the filter barrel. Clean water is added through the water inlet hole 414 to clean the sludge on the impurities flowing into the gap 416. Specifically, clean water is injected from the water inlet hole into the gap 416 of the filter barrel 4 through an external water source. When using clean water to clean the sludge on the gravel, the injection of clean water can effectively clean the sludge on the gravel and effectively dilute the saline-alkali components inside the sludge.

[0042] Refer to the attached Figure 2 , 3 and the attached Figures 9 - 12 , in the embodiment of the present application, an inclined panel 404 is provided in the gap 416. An airbag 405 is provided at the lower end of the inclined panel. A third through hole 401 is provided at the bottom of the inner barrel 415. A filter screen 406 is provided outside the third through hole 401. The filter screen 405 is annularly arranged outside the third through hole 401. Through the design of the third through hole 401, the inclined panel 404, the airbag 405 and the filter screen 406, when injected into the gap 416 of the filter barrel 4 through the water inlet hole and using clean water to clean the sludge on the gravel, the injection of clean water cleans the sludge on the gravel. The filter screen 406 filters the gravel and isolates it outside the filter screen. The sludge liquid on the gravel that has been cleaned is discharged through the third through hole 401 into the gap between the blanking barrel 106 and the inner barrel 415 and flows into the middle barrel from the inner barrel 415. In the present application, the injection of clean water enables the sludge on the gravel to be effectively cleaned, and the injection of clean water enables the sludge liquid on the gravel that has been cleaned to flow into the middle barrel through the inner barrel 415, which can dilute the separated sludge, reduce the concentration of saline-alkali components and organic substances in the sludge, and reduce the harm of the treated sludge to the environment and organisms. The design of the inclined panel 404 and the airbag 405, when treating the sludge on the gravel, by inflating the airbag 405 provided at the lower end of the inclined panel 404, after the airbag 405 is inflated, it can push the inclined panel 404 to move upward in the gap 416, so that the inclined panel can push the gravel upward, which is convenient for the treatment of the centrifuged gravel, saving time and effort.

[0043] It should be noted that in the present application, the design of the inclined panel 404 and the airbag 405, on the one hand, due to the irregularity of the gravel, the inclined surface of the inclined panel can make the contact point between the inclined panel and the gravel change continuously during the process of the inclined panel pushing the gravel upward, so that the gravel will gradually adjust its position under the action of the inclined panel, reducing the situation of being stuck or blocked with each other, and thus smoothly moving upward. On the other hand, by inflating the airbag 405 to push the inclined panel 404 to move upward in the gap 416, the inclined panel can push the gravel upward, which can avoid the gravel blocking the filter screen and the third through hole, so that the sludge liquid on the gravel that has been cleaned cannot enter the inner barrel 415 and flow into the middle barrel through the inner barrel 415, affecting subsequent operations.

[0044] Referring to the attached drawings, in the present application, a circular plate 407 is axially connected to the outside of the upper barrel. A circular plate rod 408 is connected to the lower end of the circular plate 407.
