Description

Technical Field

[0001] This invention relates to the field of sludge treatment equipment, and more specifically, to an aquaculture bottom sludge treatment equipment. Background Technology

[0002] Aquaculture, as one of the fastest-growing industries in agriculture, plays an important role in ensuring market supply, increasing farmers' income, optimizing the national dietary structure, and ensuring food security. However, with the continuous increase in stocking density and feed input, the large amount of uneaten feed, feces, and other mixed sediments deposited at the bottom of ponds not only puts pressure on wastewater treatment but also causes a series of problems such as aquaculture water pollution. For this type of sediment, a relatively innovative method is to use it as the main raw material for shaped biomass fuel. By adjusting and controlling the formula ratio and preparation method, the processing difficulty and production cost of biomass fuel can be reduced, the calorific value of biomass fuel can be increased, and the release of harmful substances can be reduced, so that it can be effectively utilized.

[0003] In the above method, the bottom sediment needs to be pretreated before entering the process flow, mainly for dewatering. However, most current dewatering equipment relies solely on centrifugal dewatering and lacks auxiliary treatment structures. This is especially true for dewatering bottom sediment with a certain level of moisture and viscosity, where there is still room for improvement in dewatering efficiency. Summary of the Invention

[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 3 As shown in the figure, a specific embodiment of the present invention discloses an aquaculture bottom sediment treatment device, including a water tank 100 and a dewatering device 200; the top of the water tank 100 is open and a tank cover 110 is installed; the dewatering device 200 includes a support cylinder 210, a drive mechanism 300, and a pressing mechanism 400; the support cylinder 210 is installed on the tank cover 110, and the bottom of the support cylinder 210 extends into the water tank 100; the drive mechanism 300 is provided with a turntable structure 310 corresponding to the bottom of the support cylinder 210, and the turntable structure 310 is driven to rotate by a motor 320; a filter cylinder 500 is provided inside the support cylinder 210, and the bottom of the filter cylinder 500 is detachably connected to the turntable structure 310, and the filter cylinder 500 rotates with the turntable structure 310; a cylinder cover 220 is installed on the top of the support cylinder 210, and the pressing mechanism 400 is installed on the cylinder cover 220, and a pressure plate 410 that can extend and retract into and out of the filter cylinder 500 is provided on the pressing mechanism 400.

[0037] The aforementioned aquaculture sediment treatment equipment features a filter cylinder that rotates with a turntable structure, utilizing centrifugal force for dewatering. The pressing mechanism, through the downward pressing plate, squeezes the sediment inside the filter cylinder, achieving a certain degree of pressure filtration and dewatering. Furthermore, the coordinated operation of both mechanisms allows for synchronous operation, further enhancing the dewatering effect and improving work efficiency.

[0038] The bottom of the filter cartridge can be detachably connected to the turntable structure, which facilitates the removal and replacement of the filter cartridge, thereby quickly removing the dewatered filter residue and adding the bottom sludge to be treated, thus improving the overall efficiency.

[0039] Furthermore, such as Figures 4 to 8 As shown, the drive mechanism 300 includes a turntable structure 310, a motor 320, and a second rotating shaft 330. The turntable structure 310 includes a tray 311, and a first rotating shaft 312 is fixedly mounted in the center of the bottom surface of the tray 311. The first rotating shaft 312 is rotatably mounted on a support frame 600 inside the water tank via bearings. The motor is mounted on the tank cover. The second rotating shaft is connected to the output shaft of the motor via a coupling. The second rotating shaft 330 extends into the water tank 100 and is rotatably mounted on the support frame 600 via bearings. The second rotating shaft 330 and the first rotating shaft 312 are connected by a sprocket and chain assembly. The motor drives the tray through the transmission of the first rotating shaft, the second rotating shaft, and the sprocket and chain assembly, so that the motor can be installed outside the water tank without considering the waterproofing of the motor and the electrical connection parts.

[0040] A raised ring 313 is fixedly provided on the top edge of the tray 311, and an annular groove 314 in a closed loop around the axis is provided on the inner wall of the raised ring 313. A locking structure 510 is provided on the bottom side wall of the filter cartridge 500. The locking structure 510 engages with the annular groove 314 to prevent the filter cartridge from detaching from the tray. A first prism-shaped locking block 315 is fixedly provided in the middle of the top surface of the tray 311. A first locking groove 520 is provided on the bottom surface of the filter cartridge 500. The first locking groove and the first locking block are adapted to each other. The filter cartridge rotates with the tray through the engagement of the first locking groove and the first locking block. A plane bearing is installed between the bottom surface of the tray and the top surface of the bracket to provide rolling support for the tray. With the overall cooperation, the locking structure and the annular groove make the filter cartridge locked on the tray and will not detach without being actively unlocked and removed. The first locking groove and the first locking block ensure that the filter cartridge rotates with the tray to achieve an effective centrifugal rotation dewatering effect.

[0041] Furthermore, such as Figure 9As shown, the bottom sidewall of the filter cartridge 500 is provided with a set of symmetrically arranged guide grooves 530. The two sides of the first slot 520 are provided with slots 540 corresponding to the guide grooves 530. The end faces of the guide grooves 530 and the slots 540 are connected through guide holes 550. The locking structure 510 includes a spring 511 and a locking tongue 512. The shape of the locking tongue matches the shape of the guide groove, and the locking tongue 512 slides tightly against the groove wall of the guide groove 530. A guide rod 513 is fixedly provided on the inner end face of the locking tongue 512, and the guide rod 513 movably passes through the guide hole 550. A retaining spring is installed at the end of the guide rod extending into the bayonet. The spring 511 is sleeved on the outside of the guide rod 513, providing an outward pushing force for the locking tongue 512. The shape of the end of the locking tongue 512 away from the guide rod 513 is adapted to the cross-sectional shape of the annular groove 314. The locking tongue 512 is engaged in the annular groove 314 to achieve locking. The overall structure is simple. The locking mechanism uses a telescopic movement to lock and unlock. When the locking tongue extends and is engaged in the annular groove, it maintains the locking effect. When the locking tongue retracts, it disengages from the annular groove and unlocks. The adjustment method is simple and easy to operate.

[0042] Furthermore, the end of the locking tongue furthest from the guide rod has a narrowing structure that converges towards the horizontal center, forming two first inclined surfaces at this end. The groove opening of the annular groove has a trapezoidal cross-section, and its upper and lower walls form two second inclined surfaces that fit the end of the locking tongue. The second inclined surfaces slide and engage with the first inclined surfaces. In addition, the top of the inner ring of the convex ring has a chamfer, which also forms a third inclined surface that slopes towards the center of the convex ring and can slide and engage with the first inclined surface. With the design and coordination of the overall structure, the locking tongue can retract under the action of the inclined surfaces during the upward or downward movement of the filter cartridge, thereby achieving the effect of disengagement.

[0043] The locking tongue 512 has a first insertion hole 514 penetrating the upper and lower walls at the end away from the guide rod 513; at least two guide rings 560 are fixedly provided on the outer wall of the filter cartridge 500 corresponding to one locking tongue, and a pull rod 570 is inserted through the two guide rings 560 on the same side. A handle 571 is detachably installed at the top of the pull rod 570, and the bottom end of the pull rod 570 can be inserted into the first insertion hole 514 to prevent the locking tongue 512 from retracting into the guide groove 530 and maintain the locking of the locking tongue and the annular groove; when the handle is pulled upward, the pull rod can be disengaged from the locking tongue, releasing the restriction on the locking tongue; this structural design allows the locking tongue to be moved by the extension and retraction of the pull rod. A second restriction is applied: when the lever is inserted into the first socket, the latch cannot move, remaining extended to maintain the desired locking effect. Under this restriction, the latch can only resume its telescopic function after the handle is pulled upwards until the lever disengages from the latch. This is equivalent to pulling the handle and lever as the unlocking action. Whether placing the filter cartridge on the tray or lifting it from the tray, the handle must be pulled to the preset position to effectively prevent the filter cartridge from detaching from the tray. The action of pulling the handle and lever corresponds to the action of lifting the filter cartridge, conforming to actual usage and facilitating operation.

[0044] Furthermore, the top of the outer wall of the filter cartridge 500 is fixedly provided with handles 580 corresponding to the two handles 571. When the handle is pulled up to abut against the handle, the bottom end of the pull rod disengages from the first insertion hole. When the bottom surface of the handle abuts against the top surface of the guide ring at the top position, the bottom end of the pull rod extends into the first insertion hole without protruding from the bottom surface of the locking tongue. By setting the so-called limit position for the handle to move up, it is ensured that the pull rod disengages from the locking tongue when the handle moves to this position, thereby unlocking. On the other hand, it allows the handle to be close to the handle for better gripping and force application, making it easier to lift and place the filter cartridge. The guide ring can limit the movement of the pull rod, allowing the pull rod to accurately insert into the first insertion hole. On the other hand, the guide ring at the top position can be used as a blocking component to limit the downward movement of the handle, keeping the handle in a position that is easy to grip and preventing the pull rod from going down too far, which would affect the subsequent dragging and unlocking action.

[0045] Furthermore, the first insertion hole has a rectangular hole structure, and the bottom edge of the pull rod is chamfered, which makes it easy to insert the pull rod into the first insertion hole. Even if it comes loose, the locking tongue and the annular groove can still be matched to maintain the locking effect.

[0046] Furthermore, such as Figure 5 , Figure 6As shown, the pressing mechanism 400 includes a pressure plate 410 and an electric push rod 420; the bottom surface of the cylinder cover 220 is provided with a settling groove 221, and the center of the top surface of the cylinder cover is provided with a through hole 222 communicating with the settling groove; the electric push rod 420 is installed on the top surface of the cylinder cover 220, the pressure plate 410 is located at the settling groove 221, and an insertion tube is fixedly provided on the top surface of the pressure plate 410. The piston rod end of the electric push rod 420 is inserted into the insertion tube and connected by a pin, and the electric push rod drives the pressure plate to move vertically; the pressure plate moves vertically in and out of the filter cylinder under the drive of the electric push rod. When the pressure plate moves downward, it can press the bottom mud in the filter cylinder with force, so as to promote the removal of impurities in the bottom mud. The seepage of water achieves a pressure filtration effect. When the electric push rod retracts the piston rod, the pressure plate can be stored in the settling tank, preventing the pressure plate from affecting the opening and closing of the cylinder cover. Furthermore, the diameter of the pressure plate is adapted to the inner diameter of the filter cylinder, and a rubber pad is fixedly attached to the top surface of the pressure plate. The outer side of the rubber pad slides against the inner wall of the filter cylinder, providing an effective pressing effect and providing the necessary pressure to the soil, accelerating the precipitation of the mixed liquid. Under this structural constraint, the pressure plate will not hinder the rotation of the filter cylinder, and can even assist the rotation, preventing the filter cylinder from shaking randomly, allowing the filter cylinder to rotate smoothly and achieve effective dewatering.

[0047] The filter cartridge has a chamfered edge on the top inner wall to facilitate the accurate entry of the pressure plate into the filter cartridge.

[0048] Furthermore, such as Figure 1 , Figure 3 As shown, a clamping groove is fixedly provided on the top outer wall of the support cylinder, and a protrusion is fixedly provided on one side of the cylinder cover. The protrusion is located in the clamping groove and is rotatably connected to the cylinder cover through a shaft. The cylinder cover and the other side of the support cylinder are connected by a buckle. A feeding pipe 120 is connected to the top surface of the box cover 110, and a sealing cover 130 is installed at the top of the feeding pipe 120. The feeding pipe 120 is located on the side of the cylinder cover 220 that is flipped. After the cylinder cover 220 is flipped, the side away from the shaft is pressed against the sealing cover 130, so that the cylinder cover and the electric push rod are in an elevated position. The cylinder cover has a flip-top structure, which can be opened and closed easily, and facilitates the removal and placement of the internal filter cartridge. Furthermore, the feeding pipe and the sealing cover are used as the support parts for the cylinder cover after it is flipped up. On the one hand, this facilitates the subsequent closing action of the cylinder cover. On the other hand, it can prevent the electric push rod from colliding or being damaged with the box cover. It can also facilitate the disassembly and replacement of the electric push rod and the pressure plate.

[0049] Furthermore, such as Figure 10As shown, the support cylinder 210 has a sleeve 230 inside, and the axis of the sleeve coincides with that of the support cylinder. The bottom end of the sleeve 230 is connected to the bottom end of the support cylinder 210 by multiple support bars 240 arranged in a circular array around the center. A cavity 250 is formed between the outer wall of the sleeve 230 and the inner wall of the support cylinder 210. The cylinder cover 220 is provided with multiple exhaust holes 223 through the cavity 250. An adsorbent 700 is provided in the cavity 250 to adsorb the odor of the gas passing through. This structural design can use the cavity and exhaust holes as a way for the gas inside the water tank to be discharged. By installing an adsorbent in this way, the odor in the gas can be adsorbed and treated, reducing the emission of odor.

[0050] Furthermore, such as Figure 5 As shown, the adsorption element 700 includes a sleeve 710, the inner diameter of which is adapted to the outer diameter of the sleeve 230; the outer wall of the sleeve 710 is provided with an adsorption layer 720, which is made of activated carbon adsorption material, including but not limited to activated carbon blocks or activated carbon filter cotton; it is made into a sleeve-shaped structure that is adapted to the shape of the outer wall of the sleeve, adapts to the internal shape of the cavity, and also leaves a flow channel for the gas path, so as to perform physical adsorption treatment on the exhaust gas and achieve the deodorization effect.

[0051] The thickness of the sleeve and the adsorption layer is less than the thickness of the clamping cavity. The top of the sleeve 710 is higher than the top of the sleeve 230. The top of the sleeve 710 has strip-shaped openings 730 on both sides for gripping, which facilitates picking up and putting down. The overall structural design makes the adsorption component a detachable and replaceable part, which is convenient for actual production and application.

[0052] Furthermore, it also includes an aeration device, which includes an air supply pipe installed on the bottom of the inside of the water tank. An aeration disc is installed on the air supply pipe, and the air inlet of the air supply pipe extends out of the water tank and is connected to the air outlet of a blower (not shown). Oxygen is injected into the water tank through air supply and aeration to facilitate the reproduction of internal microorganisms and provide the necessary oxygen for the microorganisms to decompose pollutants, thereby achieving the effect of biological purification. In addition, the aeration method can also agitate the wastewater to ensure that the added chemicals are fully dissolved and diffused, thereby enhancing the purification effect.

[0053] Furthermore, it also includes a circulating spraying device, which includes a water pump, a spray pipe, and a water supply pipe. The spray pipe is mounted on a support frame and has a ring-shaped structure, corresponding to the lower outer side of the support cylinder. The output port of the water pump is connected to the spray pipe through a first water supply pipe, and a second water supply pipe is connected to the inlet of the water pump. The two ends of the second water supply pipe extend to the bottom of one side wall of the water tank and are connected to the inside of the water tank. The water pump draws the liquid at the bottom of the water tank towards the spray pipe, forming a circulating spraying effect. On the one hand, it can promote the dissolution, diffusion, and mixing of the agent. On the other hand, it can also allow the odor in the sewage to enter the clamping cavity better with the airflow sent out by the aeration through the spraying method, and then the odor is adsorbed and treated by the adsorption element, reducing the emission of odor.

Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. This invention is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims are also within the protection scope of this invention.
