Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture wastewater treatment, and particularly relates to an efficient precipitation device for aquaculture wastewater. Background Art

[0002] The concentration of suspended solids and organic matters in aquaculture wastewater is relatively high. These suspended solids not only have high nitrogen and phosphorus contents, but also consume a large amount of oxygen during decomposition. The most widely used treatment process for removing suspended solids in aquaculture wastewater is precipitation. At present, the main precipitation methods in the current process are natural precipitation in sedimentation tanks and chemical flocculation precipitation. However, the natural precipitation method has poor removal effect on suspended solids in aquaculture wastewater.

At the same time, in the description of the present utility model, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0026] Please refer to Figures 1 to 5 , the present utility model provides an efficient sedimentation device for aquaculture wastewater. In the prior art, the efficiency of wastewater treatment is often low. To solve the above technical problems, the present utility model optimizes the scheme to achieve the purpose of improving the efficiency of wastewater treatment.

[0027] It includes a filter tank 10, a flocculation tank 20, and a sedimentation tank 30 connected in sequence. A filter lifting net 11 is arranged at the top of the filter tank 10, and a filter screen 12 is arranged near the bottom of the filter tank 10. The area between the filter lifting net 11 and the filter screen 12 is the wastewater sedimentation area. The main function of the filter lifting net 11 is to filter large impurities, and the purpose of the filter screen 12 is to separate out some heavier sediments. After the wastewater is preliminarily sedimented in the filter tank 10 for a period of time, the wastewater is transferred to the flocculation tank 20 through an output pipe for chemical reaction and sedimentation.

[0028] The flocculation tank 20 is a tank-shaped structure. A detachable cover plate 40 is provided at the top of the flocculation tank 20, and two dosing mechanisms 100 are provided on the cover plate 40. The dosing mechanisms 100 are located on both sides of the cover plate 40. Two waste storage boxes 50 are arranged between the two dosing mechanisms 100. The wastewater after preliminary sedimentation in the filtration tank 10 is transferred into the waste storage boxes 50, and a number of liquid injection ports are provided on both sides of the bottom of the waste storage boxes 50 to transfer the waste liquid into the flocculation tank 20. A driving motor 60 is also arranged between the two waste removal boxes. The output shaft of the driving motor 60 is in transmission connection with a stirring shaft 61. The stirring shaft 61 is arranged in the flocculation tank 20, and stirring blades 62 are arranged on the stirring shaft 61.

[0029] The dosing mechanism 100 mainly includes a medicine storage tank 110. The liquid medicine in the medicine storage tank 110 is a conventional purification medicine. A medicine delivery pipe is provided at the bottom of the medicine storage tank 110 to deliver the liquid medicine in the medicine storage tank 110 into the flocculation tank 20 through the medicine delivery pipe. A dispersion plate 120 is correspondingly arranged at the bottom of the medicine delivery pipe. A number of dispersion holes are provided on the dispersion plate 120. A distribution plate is arranged at the bottom of the dispersion plate 120, and a number of distribution holes are provided on the distribution plate. The dispersion plate 120 and the distribution plate can move relative to each other, so as to evenly disperse the liquid medicine in the flocculation tank 20. Under the action of the stirring shaft 61, it can be quickly fused into the wastewater, achieving the purpose of improving the efficiency of chemical treatment.

[0030] The relative movement between the dispersion plate 120 and the distribution plate is realized through a transmission component. The transmission component includes an installation box, which is fixedly arranged on the inner wall of the flocculation tank 20. An installation seat 141 is arranged in the installation box. Two movable cavities 142 are arranged at the top of the installation seat 141. The two movable cavities 142 are arranged side by side. A slider 122 is arranged in one of the movable cavities 142, and an installation shell 132 is arranged in the other movable cavity 142. A transmission motor is arranged in the installation shell 132. Both the installation shell 132 and the slider 122 can move in the movable cavity 142. The top of the installation shell 132 is connected to the end of the distribution plate 130 through a connecting rod 131, and the top of the slider 122 is connected to the end of the dispersion plate 120 through an installation frame 121. The installation frame 121 is in a convex shape. Further explanation here is that the ends of the distribution plate 130 and the dispersion plate 120 are not at the same end, but at the opposite ends. The output end of the transmission motor is connected to a cam-shaped turntable 133. A rocker 134 is sleeved on the turntable 133, and the free end of the rocker 134 is sleeved on the slider 122. Under the driving force of the transmission motor, the installation shell 132 and the slider 122 reciprocate in the movable cavity 142.

[0031] In order to facilitate the installation of the rocker 134, an extension column 124 is also arranged on the side wall of the slider 122, so that the free end of the rocker 134 can be sleeved outside the extension column 124.

[0032] In order to enable the installation shell 132 and the slider 122 to slide relatively stably, a first reciprocating spring 143 and a second reciprocating spring 144 are respectively arranged in the movable cavity 142. An installation frame 121 in a concave shape is provided on the outer wall of one end of the dispersion disc 120. A slider 122 is provided at the bottom of the installation frame 121. Through rods 123 are provided at both ends of the slider 122, and the through rods 123 are inserted into the first reciprocating spring 143. Insertion rods 135 are provided at both ends of the installation shell 132 and are inserted into the second reciprocating spring 144.

[0033] In order to further limit the movement of the installation shell 132 and the slider 122, the installation seat 141 is further limited. Specifically, the installation seat 141 includes a base. A partition column 145 is provided in the middle of the base. Fence plates 146 are provided at both ends of the top of the partition column 145. The two fence plates 146 form a slide rail. The receiving rod 131 and the installation frame 121 are placed in the slide rail so that they will not move randomly. At the same time, the installation of the first reciprocating spring 143 and the second reciprocating spring 144 is further limited. Specifically, the first reciprocating spring 143 is installed between one side of the partition column 145 and the base, and the second reciprocating spring 144 is installed between the other side of the partition column 145 and the base.

[0034] In the flocculation tank 20, under the action of the stirring shaft 61, the dispersion disc 120, and the dispensing disc 130, the liquid medicine and the wastewater are fully and efficiently fused and a chemical reaction occurs, so as to achieve the purpose of quickly treating the wastewater. After being treated in the flocculation tank 20, the treated wastewater is transferred to the sedimentation tank 30 through the output pipe. A number of sedimentation inclined plates 31 are provided in the sedimentation tank 30. A sediment collection cavity 32 is provided at the bottom of the sedimentation inclined plates 31 to collect the sediment. The treated wastewater is then transferred out through the side wall of the sedimentation tank 30 and then undergoes other purification procedures.

[0035] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
