Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, in particular to a device for treating aquaculture wastewater. Background Art

[0002] Aquaculture wastewater contains a large amount of organic matter, such as leftover bait and feces. Once these organic matter enters natural water bodies, they will cause eutrophication of the water bodies. In aquaculture, the pH value of the water body is a key water quality parameter. It directly affects the physiological activities, growth, development and survival of farmed organisms, and seriously damages the balance of the aquatic ecosystem.

[0003] The existing aquaculture wastewater treatment device connects the breeding pond and the treatment device body through a water pipe, and then drives the pump body to transport the wastewater into the device to filter and treat it through the filter screen and activated carbon plate, and then inputs the reagent into the device body through the pipeline to adjust the pH value, so as to mix it through the stirring plate. The existing device body adopts the method of directly adding the reagent into the interior. When a large amount of wastewater is input into the device by a large breeding pond, it is difficult to evenly disperse the reagent in the entire wastewater in a short time after it is added, resulting in poor mixing effect. In addition, the existing wastewater treatment devices are of various sizes, including square, round and other shapes, and the internal storage capacity is large. The amount of chemicals is different, so the internal storage capacity of these different wastewater treatment devices is also different, which makes it difficult to determine the amount of chemicals needed to adjust the pH value of the wastewater and to achieve accurate dosage adjustment. This not only increases the complexity of the operation, but also leads to unstable treatment effects. It is impossible to ensure that the pH value of the wastewater can be adjusted to the appropriate range every time. In terms of adjusting the pH value, the concentration of chemicals in some areas will be too high, while the concentration of chemicals in other areas will be too low. This will not only affect the uniformity of pH adjustment, but also lead to insufficient or excessive local chemical reactions, resulting in undesirable by-products, and even affecting subsequent treatment processes and the final wastewater discharge compliance rate.

[0004] In response to the above problems, an innovative design was carried out based on the original aquaculture wastewater treatment device. Summary of the Invention

The four groups of rotating plates 155 are initially inclined, ensuring that the drug and wastewater are mixed in a suitable proportion, ensuring the accuracy and stability of pH value adjustment, and improving the consistency of treatment effect.

[0037] The top of the turnover structure 17 is rotatably connected to the mixing extension structure 18, which includes rotating rods 181 respectively arranged on one side of the planetary gear set.

The surface of each group of rotating columns 183 is staggered with mixing rods 184. There are several mixing rods 184 distributed. The four groups of rotating columns 183 and the mixing rods 184 rotate while rotating, so that the wastewater and chemicals at different positions in the treatment tank 12 can be fully mixed, avoiding the situation of local uneven mixing.

[0038] Bumps 19 are provided on both sides of the water pressure plate 16, and a telescopic spring 21 for resetting is provided at the bottom end of the bump 19. A slide groove 20 is provided inside the processing tank 12, and the bump 19 slides in the slide groove 20. The end of the telescopic spring 21 away from the bump 19 is connected to the slide groove 20 for easy return.

[0039] The medicine storage assembly 13 includes a support frame 134 fixedly installed on the top of the processing tank 12, and a medicine tank 131 is fixedly installed inside the support frame 134. The top of the medicine tank 131 is connected to a medicine inlet pipe 132, and the bottom end of the medicine tank 131 is connected to a medicine outlet pipe 133. A circular opening is opened on the top surface of the processing tank 12, and the medicine outlet pipe 133 passes through the circular opening and extends into the interior of the processing tank 12 to facilitate the addition of medicines.

[0040] The rotating rod 181 is connected to the planetary gear 178 respectively. A cavity 185 is provided inside the rotating column 183. A built-in column 186 is slidably connected inside the cavity 185. A spring 182 is provided at the bottom end of the built-in column 186. The end of the spring 182 away from the built-in column 186 is connected to the bottom end of the cavity 185. A receiving groove 187 is provided on the surface of the built-in column 186. There are four groups of receiving grooves 187 at equal intervals. Spring hinges 188 are provided inside the four groups of receiving grooves 187 respectively. One side of the four groups of spring hinges 188 is provided with an expansion plate 189 for mixing the medicine. One side of the device body 1 is connected to a connecting pipe 4 for adding flocculant. The connecting pipe 4 is connected to the third chamber 10, and the return pipe 14 is connected to one side of the treatment tank 12, and the return pipe 14 is connected to the second chamber 8. The water inlet pipe 2, the water outlet pipe 3, the water supply pipe 11 and the return pipe 14 are respectively connected to the pump body, and the pump body is used for the input and output of water. One side of the device body 1 is connected to the connecting pipe 4 for inputting flocculant, and the connecting pipe 4 is connected to the third chamber 10. The return pipe 14 is connected to one side of the treatment tank 12, and the return pipe 14 is connected to the second chamber 8. The water inlet pipe 2, the water outlet pipe 3, the water supply pipe 11 and the return pipe 14 are respectively connected to the pump body, and the pump body is used for the input and output of water, which improves the stability and reliability of the overall treatment effect.

[0041] Specifically, during use, since one end of the water inlet pipe 2 is connected to the aquaculture pond, and the other end of the water inlet pipe 2 is connected to the device body 1, when the wastewater from the aquaculture pond needs to be treated, the operator starts the pump body connected to the water inlet pipe 2, so that the wastewater inside the aquaculture pond is input into the first chamber 7 of the device body 1 through the negative pressure suction of the pump body through the water inlet pipe 2 for primary treatment. Since the first chamber 7 is provided with a filter screen 6 fixed by a receiving box 5, large impurities such as leftover bait, aquaculture residues and leaves in the wastewater are filtered out, the receiving box 5 is provided with a side block through the top, and the side block is fixedly connected to the filter screen 6. The top of the receiving box 5 is open, so that there is a distance between the top surface of the receiving box 5 and the filter screen 6. After the wastewater passes through the filter screen 6 and the large impurities are filtered out, it flows into the interior of the receiving box 5 and gathers, which is convenient for filtering and collecting the large impurities in a unified manner.

[0042] Secondly, the pump body of the water delivery pipe 11 is started to input the waste water accumulated in the receiving box 5 into the interior of the treatment tank 12. Since the interior of the treatment tank 12 is slidably connected with the water pressure plate 16, and the bottom ends of the protrusions 19 on both sides of the water pressure plate 16 are provided with telescopic springs 21 for resetting, as a certain amount of waste water is input into the treatment tank 12, a certain amount of reagent is added to the interior of the treatment tank 12 for mixing and reacting, and then the pH value of the waste water is adjusted to a suitable value, and the pump body drive is stopped. This can be completed by controlling the pump body, which is a prior art and will not be described in detail here, thereby accumulating the waste water at the top of the water pressure plate 16. The gravity of the wastewater will press the water pressure plate 16 downward, so that the water pressure plate 16 slides downward in the corresponding chute 20 through the connected protrusion 19. The protrusion 19 squeezes and stores force on the telescopic spring 21. The amount of medicine can be accurately controlled by changing the position of the water pressure plate 16, thereby avoiding waste and excessive addition of medicine, ensuring a reasonable ratio of wastewater and medicine, and improving the use efficiency and treatment effect of the medicine. No matter how much storage capacity the wastewater treatment device has, it can complete the quantitative dosing work through the treatment tank 12, the medicine storage component 13, the quantitative dosing structure 15 and the mixing expansion structure 18, and has a wide range of uses.

[0043] Since a medicine tank 131 is fixedly installed on the top of the treatment tank 12 by a support frame 134, the top of the medicine tank 131 is connected to a medicine inlet pipe 132 for external medicine supplementation, so that the bottom end of the medicine tank 131 is connected to a medicine outlet pipe 133, and a circular opening is provided on the top surface of the treatment tank 12, and the medicine outlet pipe 133 extends into the interior of the treatment tank 12 through the circular opening, and a rotating ball 157 is connected to the interior of the medicine outlet tank 131 by rotating through an axis, and a feeding channel 158 is provided inside the rotating ball 157. In the initial state, the feeding channel 158 of the rotating ball 157 is consistent with the feeding direction of the medicine outlet pipe 133, so that the liquid medicine for adjusting the pH value of the wastewater in the medicine tank 131 flows into the medicine outlet pipe 133, and then the medicine in the medicine outlet pipe 133 flows into the interior of the medicine storage cartridge 152 through the feeding channel 158 of the rotating ball 157 for subsequent quantitative feeding. The downward sliding of the pressing plate 16 drives the telescopic rod 151 fixed at the top by the fixed shell 1710 to expand. After the telescopic rod 151 is expanded, it drives the medicine storage cartridge 152 at the top to move downward. The medicine storage cartridge 152 drives the rack 1510 at the top to move downward and engage with the gear 159 on the outside of the rotating shaft 156 to rotate. The gear 159 drives the rotating ball 157 to rotate 90 degrees, so that the discharge channel 158 is blocked, preventing the medicine in the medicine discharge pipe 133 from flowing out, and the top of the medicine storage cartridge 152 is lower than the bottom of the medicine discharge pipe 133. Since the initial state of the rotating plate 155 is inclined, the four groups of flared openings 153 opened on the surface of the medicine storage cartridge 152 are connected by the spring hinge 154. The rotating plate 155 is not squeezed back by the wall of the medicine discharge pipe 133, so that the four groups of rotating plates 155 are reversed and expanded by the corresponding spring hinge 154. Figure 6As shown, the agent inside the drug storage cartridge 152 flows out through the flared openings 153 to mix with the wastewater. Because the bottom end of the drug storage cartridge 152 is curved, the agent can be discharged more quickly through the four sets of flared openings 153. The agent storage capacity of the drug storage cartridge 152 is proportional to the amount of wastewater input into the treatment tank 12. This ratio is calculated based on previous experiments and can automatically achieve quantitative drug dispensing based on the amount of wastewater. This ensures that the agent and wastewater are mixed at the appropriate ratio, ensuring the accuracy and stability of pH adjustment, improving the consistency of the treatment effect, and enhancing the stability and reliability of the overall treatment effect.

[0044] As the water pressure plate 16 slides downward, since a rod groove is provided inside the water pressure plate 16, the rotating rod 173 is rotatably connected to the rod groove, the gear 2 172 provided at one end of the rotating rod 173 is engaged with the rack 2 171 correspondingly provided inside the processing tank 12, the gear 2 172 drives the bevel gear 1 174 and the bevel gear 2 175 at one end of the rotating rod 173 to engage, and the bevel gear 2 175 drives the driven rod 176 at one end to rotate, and the driven rod 176 is rotatably connected to the rod groove, and an opening is provided on the bottom surface of the fixed shell 1710, and the top end of the driven rod 176 passes through the opening and extends into the interior of the fixed shell 1710, and the driven rod 176 drives the sun gear 177 at the top to rotate. Since the fixed shell 1710 is provided with a ring gear 179 inside, the sun gear 177 drives the four sets of planetary gears 178 on the outside to mesh with the ring gear 179, so that the rotating rod 181 is correspondingly provided on one side of the four sets of planetary gears 178. The rotating rod 181 slides in the circular groove 1711, and the four sets of rotating rods 181 respectively drive the corresponding rotating columns 183 to rotate while rotating. The surface of each set of rotating columns 183 is staggered with mixing rods 184. The mixing rods 184 mix the reagents and wastewater to accelerate the reaction efficiency. As the water pressure plate 16 moves, the top of the four sets of rotating columns 183 is not pressed by the top of the inner part of the treatment tank 12, such as Figure 9 As shown, in the initial state, the four groups of expansion plates 189 are rotated into an inclined state through the spring hinge 2 188, so that the spring 182 at the bottom end of the built-in column 186 slidably connected in the internal cavity 185 of the rotating column 183 releases the rebound force, so that the built-in column 186 slides upward and extends out of the top end of the rotating column 183, so that the expansion plates 189 connected by the spring hinge 2 188 in the four groups of receiving grooves 187 opened on the surface of the built-in column 186 are expanded, thereby expanding the mixing range. This multi-directional movement and the staggered distribution of the mixing rod 184 can break the stratified state of the reagent and wastewater, so that they can fully contact and mix in a short time, greatly improving the uniformity and reaction efficiency of the mixing, ensuring that the pH value is adjusted quickly and accurately, and making the wastewater and reagents at different positions in the treatment tank 12 can be fully mixed, avoiding the situation of local uneven mixing, improving the stability and reliability of the overall treatment effect, and ensuring that the quality of the treated wastewater is more uniform and meets the standards;

[0045] Finally, the regulated wastewater inside the treatment tank 12 is transported back to the interior of the second chamber 8 by driving the pump body of the return pipe 14, and then the returned wastewater is filtered through the activated carbon plate 9 to filter the organic matter, and then the wastewater flows into the third chamber 10 through the activated carbon plate 9. The flocculant agent is previously input into the interior of the third chamber 10 through the connecting pipe 4 on the side of the device body 1, so that the wastewater returned through the return pipe 14 continuously flows through the activated carbon plate 9 and reacts with the flocculant agent to precipitate, which is convenient for subsequent discharge through the outlet pipe 3.
