Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and 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. When 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, which directly affects the physiological activities, growth and 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 transports the wastewater to the inside of the device through a driving pump body to filter and treat through a filter screen and an activated carbon plate, and then inputs a reagent into the inside of the device body through a pipeline to adjust the pH value, so as to mix it through a stirring plate. The existing device body adopts a method of directly adding reagents into the inside. When a large breeding pond inputs a large amount of wastewater into the device, after the reagents are added, it is difficult to evenly disperse them in the entire wastewater in a short time, resulting in a 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 The amount of chemicals is different, and thus the internal storage capacity of these different wastewater treatment devices is also different, making it difficult to determine the amount of chemicals needed to adjust the pH value of the wastewater, and it is difficult to achieve precise 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 an appropriate range every time. In terms of adjusting the pH value, the concentration of chemicals in some areas may be too high, while the concentration of chemicals in other areas may 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 rate of compliance with wastewater discharge standards.

[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

[0028] 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, one 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, four groups of receiving grooves 187 are provided at equal intervals, spring hinges 188 are provided inside the four groups of receiving grooves 187 respectively, and expansion plates 189 for mixing the reagents are provided on one side of the four groups of spring hinges 188 respectively, and a connecting pipe 4 for feeding flocculants is connected to one side of the device body 1, The connecting pipe 4 is connected to the third chamber 10, and a 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 delivery pipe 11 and the return pipe 14 are respectively connected to a 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 a 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 delivery pipe 11 and the return pipe 14 are respectively connected to a pump body, and the pump body is used for the input and output of water, thereby improving the stability and reliability of the overall treatment effect.

[0029] Specifically, when in 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 it is necessary to treat the wastewater in the aquaculture pond, 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 to filter large impurities such as residual bait, residual aquaculture products and leaves in the wastewater, the receiving box 5 is provided with a side block at 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 large impurities filtered by the filter screen 6, it flows into the interior of the receiving box 5 for aggregation, which is convenient for filtering and collecting the large impurities in a unified manner. Secondly, the pump body of the water delivery pipe 11 is started to input the wastewater collected in the receiving box 5 into the inside of the treatment tank 12. Since the inside 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 wastewater is input into the treatment tank 12, a certain amount of reagent is added into the treatment tank 12 for mixing and reaction, and then the pH value of the wastewater is adjusted to a suitable value, and the pump body drive is stopped. This can be completed by controlling the pump body, which is the prior art and is not described in detail here, so that the wastewater accumulated 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 slide groove 20 through the connected protrusion 19, and 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 medicine. No matter how much storage capacity the wastewater treatment device has, the quantitative dosing work can be completed through the treatment tank 12, the medicine storage component 13, the quantitative dosing structure 15 and the mixing extension structure 18, and the scope of use is wide; Since a medicine tank 131 is fixedly installed on the top of the treatment tank 12 through a support frame 134, a medicine inlet pipe 132 for external medicine supplement is connected to the top of the medicine tank 131, so that a medicine outlet pipe 133 is connected to the bottom of the medicine tank 131, and a circular opening is opened 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 inside of the medicine outlet tank 131 through an axis rotation, and a material discharge channel 158 is opened inside the rotating ball 157. In the initial state, the material discharge channel 158 of the rotating ball 157 is consistent with the medicine discharge 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 medicine storage cylinder 152 through the material discharge channel 158 of the rotating ball 157 for subsequent quantitative medicine discharge. 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 barrel 152 at the top to move downward. The medicine storage barrel 152 drives the rack 1510 at the top to move downward and mesh 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 unloading channel 158 is blocked, preventing the medicine in the medicine outlet tube 133 from flowing out, and the top of the medicine storage barrel 152 is lower than the bottom of the medicine outlet tube 133. Since the initial state of the rotating plate 155 is inclined, the rotating plate 155 connected by the spring hinge 154 on the surface of the medicine storage barrel 152 is not squeezed back by the tube wall of the medicine outlet tube 133, so that the four groups of rotating plates 155 are reversed and expanded through the correspondingly connected spring hinge 154. Figure 6As shown, the medicine inside the medicine storage cartridge 152 flows out through the expansion port 153 to mix with the wastewater. Since the bottom end of the medicine storage cartridge 152 is an arc surface, the medicine can be discharged more quickly through the four groups of expansion ports 153. The medicine storage volume of the medicine storage cartridge 152 is in a certain ratio with the amount of wastewater input into the treatment tank 12, which is the ratio data obtained by previous test calculations, and can automatically quantitatively discharge the medicine according to the amount of wastewater. This ensures that the medicine and wastewater are mixed at a suitable ratio, ensures the accuracy and stability of pH value adjustment, improves the consistency of the treatment effect, and improves the stability and reliability of the overall treatment effect; 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 meshes 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 mesh, the bevel gear 2 175 drives the driven rod 176 at one end to rotate, the driven rod 176 is rotatably connected to the rod groove, the bottom surface of the fixed shell 1710 is provided with an opening, the top end of the driven rod 176 passes through the opening and extends into 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 a rotating rod 181 is correspondingly provided on one side of the four sets of planetary gears 178, and the rotating rod 181 slides in the circular groove 1711. 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 ends of the four sets of rotating columns 183 are not suppressed by the inner top ends of the treatment tank 12, such as Fig. 9 As shown, in the initial state, the four groups of expansion plates 189 are rotated in 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 of the rotating column 183, so that the expansion plates 189 connected by the spring hinge 2 188 in the four groups of storage grooves 187 opened on the surface of the built-in column 186 are unfolded, thereby expanding the mixing range. This multi-directional movement and the dislocation distribution of the mixing rod 184 can break the stratified state of the reagent and the wastewater, so that they can fully contact and mix in a short time, greatly improving the uniformity and reaction efficiency of the mixing, ensuring the rapid and accurate adjustment of the pH value, and making the wastewater and the reagent 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; Finally, the regulated wastewater inside the treatment tank 12 is transported back to the second chamber 8 by driving the pump body of the return pipe 14, and then the organic matter in the returned wastewater is filtered through the activated carbon plate 9, and then the wastewater flows into the third chamber 10 through the activated carbon plate 9. The flocculant agent is previously input into 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 into the activated carbon plate 9 and reacts with the flocculant agent to precipitate, which is convenient for subsequent discharge through the outlet pipe 3.
