[0001] This utility model relates to the field of wastewater treatment technology in aquaculture, specifically to a wastewater treatment device for aquaculture. Background Technology
[0002] As is well known, sedimentation tanks are commonly used wastewater treatment facilities in aquaculture, industrial production, and municipal wastewater treatment. Their main function is to separate suspended particles, sludge, and other impurities from wastewater through gravity settling, thus achieving preliminary purification of the wastewater. However, during long-term use, traditional sedimentation tanks gradually accumulate a large amount of sludge at the bottom. If not cleaned in time, this will reduce the effective volume of the sedimentation tank, decrease the settling effect, and affect the wastewater treatment efficiency.
[0003] Currently, traditional sedimentation tank dredging methods have many problems. Many sedimentation tanks rely on manual dredging, which is not only labor-intensive and inefficient, but also exposes workers to direct contact with sewage and sludge, making them vulnerable to pathogens and harmful chemicals, posing significant safety hazards. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-4This utility model relates to a wastewater treatment device for aquaculture, comprising a sedimentation tank 1, a conveying mechanism and a sludge removal mechanism on the sedimentation tank 1, the sludge removal mechanism including a sludge removal box 2 and a slide rail 3, an electric slider 4 on the slide rail 3, a lifting mechanism 5 at the top of the electric slider 4, a connecting member 6 between the lifting mechanism 5 and the sludge removal box 2, a sliding support mechanism between the sludge removal box 2 and the sedimentation tank 1, a fan-shaped groove 7 at the bottom of one side of the sludge removal box 2, a first telescopic mechanism 8 and a second telescopic mechanism 9 at the top of the sludge removal box 2, a sealing plate 10 between the first telescopic mechanism 8 and the interior of the sludge removal box 2, and a sealing hole and a through hole on the sealing plate 10. The output end of the second telescopic mechanism 9 passes through the sealing hole and is provided with a mounting plate. A baffle 11 is provided at the bottom of one side of the mounting plate. Pressure relief ports 12 are provided on both sides of the sludge removal box 2. The pressure relief ports 12 are close to the top of the sludge removal box 2. In this embodiment, the sludge removal box 2 can be moved horizontally above the sedimentation tank 1 by the cooperation of the slide rail 3 and the electric slider 4, so as to realize sludge removal operations at different positions. The lifting mechanism 5 can adjust the height of the sludge removal box 2 to adapt to different sludge depths in the sedimentation tank 1. The first telescopic mechanism 8 controls the movement of the sealing plate 10. The sealing hole on the sealing plate 10 provides an activity channel for the second telescopic mechanism 9. At the same time, the sealing plate 10 can divide or seal the internal space of the sludge removal box 2. 9 drives the mounting plate and baffle 11 to move. Baffle 11 engages with the fan-shaped groove 7 at the bottom of one side of the sludge removal box 2. When baffle 11 moves away from the fan-shaped groove 7, the electric slider 4 is controlled to move the sludge removal box 2 horizontally. At the same time, the lifting mechanism 5 is controlled to drive the sludge removal box 2 downward, so that the fan-shaped groove 7 touches the bottom of the sedimentation tank 1, thereby squeezing the sludge into the fan-shaped groove 7 and into the interior of the sludge removal box 2. Then, the output end of the second telescopic mechanism 9 is controlled to drive the baffle 11 downward to block the fan-shaped groove 7. Subsequently, the operator places a container or other collection device for collecting sludge. Then, the lifting mechanism 5 is controlled to lift the sludge removal box 2 upward, so that the bottom of the sludge removal box 2 leaves the sewage in the sedimentation tank 1. Then, the electric slider 4 is controlled to move horizontally, thereby moving the sludge removal box 2... The slide rail 3 is longer than the sedimentation tank 1, providing sufficient leeway to move the sludge removal box 2 to one side of the sedimentation tank 1. Then, the output end of the second telescopic mechanism 9 is controlled to drive the baffle 11 away from the fan-shaped groove 7, thereby discharging the sludge. Then, the output end of the first telescopic mechanism 8 is controlled to move the sealing plate 10 downward, thereby pushing the sludge out of the fan-shaped groove 7, which can achieve sludge scraping and collection. The sliding support mechanism provides auxiliary support and guidance for the sludge removal box 2, ensuring the stability of the sludge removal box 2 during movement and operation. The pressure relief port 12 and the through hole of the sealing plate 10 are used to balance the air pressure inside the sludge removal box 2, preventing excessive air pressure from affecting the normal operation of the components.The sludge removal box 2 can move freely under the drive of the electric slider 4. The lifting mechanism 5 can adjust the sludge removal depth. The design of the baffle 11 and the fan-shaped groove 7 can effectively scrape and collect sludge, greatly improving the scope and efficiency of sludge removal and solving the problems of incomplete sludge removal and low efficiency of traditional sedimentation tanks 1. The sliding support mechanism provides stable support for the sludge removal box 2, reducing the shaking of the sludge removal box 2 during movement and operation, and ensuring the smooth progress of sludge removal operations. The pressure relief port 12 balances the internal air pressure of the sludge removal box 2, avoiding damage to the equipment caused by abnormal air pressure and extending the service life of the equipment. Targeted dredging can be carried out according to the actual situation of sludge in sedimentation tank 1. Even if there is a small amount of residue in sedimentation tank 1, it will not affect normal use. The sludge on the inner wall side of sedimentation tank 1 can also be manually pushed a short distance towards the center to solve the problem of sludge residue in the blind area of the inner wall. The electric slider is a linear motor driven electric slider: it directly converts electrical energy into mechanical energy for linear motion, omitting the intermediate conversion mechanism. Its advantages are high speed, large acceleration, high positioning accuracy, and rapid response. It can achieve high-speed and high-precision linear motion. The applicable model is the Kollmorgen AKD series linear motor module, which can accurately control the movement position of the dredging box, making the dredging operation more precise.
[0024] The lifting mechanism 5, together with the telescopic rod 19, can drive the bottom wall of the sludge removal box 2 to contact the bottom wall of the sedimentation tank 1. The telescopic rod 19 and the lifting mechanism 5 operate synchronously to clean the sludge in the sedimentation tank 1. The lifting mechanism 5 and the telescopic rod 19 can drive the bottom wall of the sludge removal box 2 to be higher than the top wall of the sewage discharge frame 20 so as to transfer the stored sludge into the sewage discharge frame 20.
[0025] To facilitate the transport of sewage, the transport mechanism in this design includes an inlet pipe 13 and an outlet pipe 14. The inlet pipe 13 is installed on one side of the sedimentation tank 1, and the outlet pipe 14 is installed on the other side of the sedimentation tank 1. The arrangement of the inlet pipe 13 and the outlet pipe 14 provides a clear channel for sewage to enter and exit the sedimentation tank 1, ensuring that sewage can be treated in an orderly manner in the sedimentation tank 1, and avoiding the retention or overflow of sewage in the sedimentation tank 1.
[0026] To improve the linear movement stability of the sludge removal box 2, in this design, the sliding support mechanism includes a chute and a U-shaped frame 15. The chute is located at the top of the sedimentation tank 1. A pulley 16 is mounted on the U-shaped frame 15, and the pulley 16 rests against the chute. A telescopic rod 19 is located at the top of the U-shaped frame 15. A mounting bracket 17 is provided between the end of the telescopic rod 19 away from the U-shaped frame 15 and the sludge removal box 2. The pulley 16 rolls within the chute, enabling the U-shaped frame 15 to move horizontally, thereby moving the sludge removal box 2. The telescopic rod 19 is adjustable in length, and the mounting bracket... 17 connects to the dredging box 2, providing support for the dredging box 2 while adapting to changes in the height of the dredging box 2. The pulley 16 on the U-shaped frame 15 rolls in the sliding groove, and together with the supporting action of the telescopic rod 19, makes the sliding support mechanism more stable and reliable in supporting the dredging box 2, reducing the vibration and displacement of the dredging box 2 during movement and operation, and improving the accuracy of dredging operations. The telescopic rod 19 can be adjusted accordingly according to the lifting height of the dredging box 2, ensuring effective support at different height positions of the dredging box 2, and enhancing the adaptability of the sliding support mechanism.
[0027] To facilitate the connection of external pipes, in this design, both the inlet pipe 13 and the outlet pipe 14 are equipped with flanges 18, which facilitate the connection of external pipes to the inlet pipe 13 and the outlet pipe 14.
[0028] To facilitate stable and reliable control of linear movement, in this design, the lifting mechanism 5, the first telescopic mechanism 8, and the second telescopic mechanism 9 are all pneumatic or electric actuators. Both pneumatic and electric actuators offer high control precision, accurately realizing the telescopic movements of the lifting mechanism 5, the first telescopic mechanism 8, and the second telescopic mechanism 9, ensuring the accuracy and reliability of the dredging operation. Providing both pneumatic and electric actuators as drive options allows for selection based on actual usage conditions, such as the availability of compressed air and power supply, enhancing the applicability of the device.
[0029] In order to improve the sealing performance of the sealing plate 10 when sealing the fan-shaped groove 7, in this solution, the bottom end of the sealing plate 10 is provided with a sealing sleeve. The sealing sleeve can improve the sealing performance of the sealing plate 10 when sealing the fan-shaped groove 7, effectively prevent the leakage of sludge or sewage in the sludge removal box 2, ensure the effect of sludge removal operation, and avoid secondary pollution.
[0030] To facilitate the storage of discharged sludge, in this design, sludge discharge frames 20 are provided on both sides of the sedimentation tank 1. The sludge discharge frames 20 are inclined and can be used to discharge sludge into cleaning boxes 2 with different fan-shaped slots 7 openings. The operator places the sludge storage box at a low position below the sludge discharge frame 20, so that the discharged sludge can fall directly into the sludge discharge frame 20, saving the operator the steps of moving and storing the storage box each time.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
