Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tanks, in particular to a sedimentation tank for treating aquaculture wastewater. Background Art

[0002] Aquaculture wastewater mainly comes from leftover feed, fish excrement and chemical substances produced during the breeding process. If it is discharged directly without treatment, it will cause serious pollution to the water environment.

[0003] During the breeding process, the floating feed fed to fish cannot be completely eaten, resulting in some feed particles remaining in the water. These feed residues are not easy to settle in the water and will gradually accumulate and form floating objects. Traditional sedimentation tanks cannot effectively intercept these floating objects, and in order to maintain the efficient operation of the sedimentation tank, it is necessary to regularly clean the sediment at the bottom. Although the sedimentation tank is designed with a sludge discharge port, the sediment cannot all be gathered at the sludge discharge port, which brings certain inconveniences to the cleaning.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] Combined with Figure 1 A sedimentation tank for treating aquaculture wastewater comprises a sedimentation tank 1, one side of the sedimentation tank 1 is provided with a sewage inlet 2, and the other side of the sedimentation tank 1 is provided with a drain outlet 3.

[0025] Through the above structure, wastewater from aquaculture enters the sedimentation tank 1 through the sewage inlet 2, is processed, and finally is directly discharged through the drain outlet 3, which is convenient for use.

[0026] Combined with Figure 3 A conical sedimentation tank 4 is provided on one side of the bottom end of the sedimentation box 1, an interception net 6 is inserted on one side of the sedimentation box 1, an arc-shaped net bag 7 is provided on the bottom end of the interception net 6, a sewage pipe 5 is provided on one side of the conical sedimentation tank 4, and a control valve is provided on the sewage pipe 5.

[0027] Through the above structure, the wastewater from aquaculture enters the sedimentation box 1, and the sediment in the wastewater slowly settles into the conical sedimentation tank 4. In addition, the interception net 6 and the arc-shaped net bag 7 can be used to directly intercept the floating objects in the wastewater, and it is convenient to take them out, so that the floating objects can be dumped, which is convenient to use.

[0028] Combined with Figure 4 Slide blocks 8 are provided on both sides of the interception net 6 , a slide groove 9 used in conjunction with the slide blocks 8 is provided on the sedimentation box 1 , and a pull ring 10 is provided on the top of the slide block 8 .

[0029] Through the above structure, the interception net 6 can be conveniently taken directly by using the slider 8 and the slide groove 9, and as the interception net 6 continues to move upward, the floating objects can be directly fished out under the action of the arc-shaped net bag 7, which is convenient to use.

[0030] Embodiment 2

[0031] Combined with Figure 2 and attached Figure 3 A motor 11 is provided on one side of the sedimentation box 1. Four rotating rollers 12 driven by the motor 11 are distributed in the sedimentation box 1. The rotating rollers 12 are connected to each other through a transmission chain plate 13. A plurality of scraper plates 14 are provided on the transmission chain plate 13.

[0032] Through the above structure, as the motor 11 is started, the four rotating rollers 12 are driven to rotate continuously under the transmission connection of the transmission chain plate 13, and the transmission chain plate 13 and the scraper plate 14 are continuously rotated, so that the sediment sunk at the bottom of the sedimentation box 1 can be directly scraped slowly to the conical sedimentation tank 4 for convenient discharge, reducing the difficulty of subsequent processing and facilitating cleaning.

[0033] Combined with Figure 2 The ends of the rotating rollers 12 extending outside the sedimentation box 1 are each provided with a pulley 15 , and the pulleys 15 are connected to each other through a belt 16 , and one end of one of the rotating rollers 12 is connected to the output end of the motor 11 .

[0034] Through the above structure, under the transmission connection of the pulley 15 and the belt 16, the four rotating rollers 12 maintain one rotation direction, the structure is simple, and the transmission is stable.

[0035] Combined with Figure 2 and attached Figure 3 A filter screen 17 is inserted into one side of the sedimentation box 1 near the drain outlet 3, and the motor 11 is directly fixed to one side of the sedimentation box 1 through a mounting frame.

[0036] Through the above structure, the filter screen 17 can be used to filter again and then discharge the wastewater, so that the wastewater can be treated multiple times with good effect. In addition, the motor 11 is directly fixed to one side of the sedimentation tank 1 through the mounting frame, and the whole is stable.

[0037] When the utility model is implemented:

[0038] The wastewater generated by aquaculture is directly discharged into the sedimentation tank 1 through the sewage inlet 2. When the wastewater enters the sedimentation tank 1, the suspended particles in the water gradually sink to the bottom of the tank due to the reduction of flow rate, forming sediment.

[0039] The intercepting net 6 and the arc-shaped net bag 7 can be used to intercept floating objects in the wastewater, and the objects can be easily taken out and dumped, which is convenient for use.

[0040] Then the sediment moves downward, some of which is directly deposited in the conical sedimentation tank 4, and some of which moves forward and is deposited at the bottom of the sedimentation box 1. The motor 11 is started, and the motor 11 drives one of the rotating rollers 12 to rotate continuously. Under the action of multiple pulleys 15 and belts 16, the multiple rotating rollers 12 are driven to rotate continuously in the same direction, and the transmission chain plate 13 and the scraper plate 14 rotate accordingly. The scraper plate 14 can be used to scrape the sediment at the bottom of the sedimentation box 1 directly into the conical sedimentation tank 4, which is convenient for discharge, reduces the difficulty of subsequent processing, and is easy to clean.

[0041] Finally, it is filtered by the filter screen 17 and directly discharged through the drain port 3.
