Description

Technical Field

[0001] The utility model relates to the technical field of hydroponic biogas slurry, in particular to an environment-friendly hydroponic biogas slurry preparation device. Background Art

[0002] Biogas slurry contains amino acids, cellulose, cellulase, protein, ribose, auxin, gibberellin, unsaturated fatty acids and some antibiotic substances. Biogas slurry is mainly used for seed soaking, foliar fertilizer spraying, mixing nutrient soil, flower and fruit protection agent, mother liquor for soilless cultivation, growing flowers and cultivating vegetables, etc. However, biogas slurry cannot be directly used for hydroponic vegetables. Before making biogas slurry into nutrient solution, it needs to be filtered and aerated.

After 5 - 8 days of planting and cultivation, continue to add an external nutrient agent to the nutrient solution, adjust the conductivity of the nutrient solution to 2 - 2.5 mS / cm, and continue to cultivate for 15 - 20 days. During the planting and cultivation process, keep the water temperature at 20 - 30 °C and perform aeration treatment every day to complete the hydroponic work of vegetables with biogas slurry. For the specific working principle of making biogas slurry into a nutrient solution, reference can be made to the patent (publication number: CN113632722A, title: A method for hydroponic vegetables using biogas slurry).

[0027] There is a connecting pipe 5 fixedly connected between the environmental protection preparation tank 3 and the biogas slurry pond 1. On one side of the environmental protection preparation tank 3 away from the connecting pipe 5, there is an inlet pipe 6 fixedly connected, and a solenoid valve one 7 is arranged on the inlet pipe 6.

[0028] The water supply mechanism includes a water supply pipe 8 fixedly installed on the top of the environmental protection preparation tank 3. A solenoid valve two 9 is arranged on the water supply pipe 8, and a pressure pump is also arranged on the water supply pipe 8.

A vertical rod 12 is fixedly connected to the threaded block one 11, and a cleaning brush 13 is fixedly connected to the vertical rod 12. The side of the cleaning brush 13 away from the vertical rod 12 abuts against the filter plate 4.

[0030] The backwashing mechanism includes a reciprocating lead screw two 14 rotatably installed on the inner wall of the environmental protection preparation tank 3. A threaded block two 15 is threadedly connected to the outer surface of the reciprocating lead screw two 14. The top of the threaded block two 15 is slidably connected to the top of the inner wall of the environmental protection preparation tank 3. A vertical pipe 16 is fixedly connected to the threaded block two 15. A number of water outlet holes 17 are opened on one side of the vertical pipe 16 close to the filter plate 4, and a flexible pipe 18 is fixedly connected to the vertical pipe 16. The other end of the flexible pipe 18 is fixedly connected to the water supply pipe 8.

[0031] The drive mechanism includes a drive motor 19 fixedly installed on the environmental protection dispensing tank 3. The output end of the drive motor 19 is fixedly connected with a driving pulley 20. A first gear 21 is coaxially and fixedly connected to the driving pulley 20. A second gear 22 meshes with the outer surface of the first gear 21. The outer surface of the driving pulley 20 is drivingly connected with a driven pulley 24 through a transmission belt 23. A third gear 25 is coaxially and fixedly connected to the driven pulley 24. A fourth gear 26 meshes with the outer surface of the third gear 25.

[0032] The first gear 21 is coaxially and fixedly connected with a first reciprocating lead screw 10 in one of the brushing mechanisms. The second gear 22 is coaxially and fixedly connected with a second reciprocating lead screw 14 in one of the backwashing mechanisms. The third gear 25 is coaxially and fixedly connected with a first reciprocating lead screw 10 in the other brushing mechanism. The fourth gear 26 is coaxially and fixedly connected with a second reciprocating lead screw 14 in the other backwashing mechanism.

[0033] A plurality of slag discharge pipes 27 are fixedly communicated with the bottom of the environmental protection dispensing tank 3. The bottom end of the slag discharge pipe 27 is threadedly connected with a collection tank 28. The number of the slag discharge pipes 27 is the same as the number of the filter plates 4.

[0034] During the cleaning process of the filter plate 4, the collection tank 28 can be screwed to release its threaded connection with the slag discharge pipe 27, so that the sewage impurities generated during the cleaning process of the filter plate 4 can be directly discharged out of the environmental protection dispensing tank 3 through the slag discharge pipe 27, and a large-capacity sewage bucket can be used for collection below the slag discharge pipe 27.

[0035] Working principle: When in use, the water, nutrient solution, biogas slurry, etc. in the biogas slurry pond 1 are fully mixed and dispensed through the cooperation of the mixing component and the aeration component, etc. When the solenoid valve 7 on the liquid inlet pipe 6 is opened, the biogas slurry can enter the environmental protection dispensing tank 3 through the liquid inlet pipe 6, and the impurities in the biogas slurry are filtered and intercepted by the multiple filter plates 4 in the environmental protection dispensing tank 3. The filtered biogas slurry flows to the biogas slurry pond 1 through the connecting pipe 5, and the biogas slurry can be used for hydroponic cultivation of vegetables through the cooperation of the aeration component (not shown in the figure) and the planting plate 2, etc.

[0036] After the filter plate 4 is used for a period of time, impurities are easily adsorbed on the surface and in the filter holes of the filter plate 4, causing blockage, and it is necessary to clean it. When it is necessary to clean the impurities on the surface and in the filter holes of the filter plate 4, the drive motor 19 and the solenoid valve 9 are turned on, and the water supply pipe 8 supplies water. The water is pressurized by a pressure pump, and the high-pressure water flow is sequentially delivered to the water outlet holes 17 through the hose 18 and the vertical pipe 16, and finally the water is sprayed out from the water outlet holes 17 to realize the reverse flushing of the filter holes on the filter plate 4, avoiding the blockage of the filter holes on the filter plate 4 and improving the subsequent filtering effect and efficiency of the filter plate 4 for the biogas slurry.

[0037] Moreover, the rotation of the output end of the drive motor 19 drives the driving pulley 20 and the first gear 21 to rotate synchronously, thereby driving the second gear 22 meshing with the first gear 21 to rotate. And through the arrangement of the transmission belt 23, the kinetic energy on the driving pulley 20 can be transmitted to the driven pulley 24, driving the driven pulley 24 and the third gear 25 to rotate synchronously, and driving the fourth gear 26 meshing with the third gear 25 to rotate. Furthermore, the first reciprocating lead screw 10 and the second reciprocating lead screw 14 are driven to rotate synchronously, driving the first threaded block 11 and the second threaded block 15 to move reciprocally, and driving the cleaning brush 13 and the vertical pipe 16 to move reciprocally. The reciprocally moving cleaning brush 13 can brush off the impurities adsorbed on the filter plate 4, improving the cleanliness of the filter plate 4, thereby improving the subsequent filtering effect and efficiency of the filter plate 4 for biogas slurry. And the reciprocally moving vertical pipe 16 facilitates the uniform flushing of the filter holes on the filter plate 4, effectively improving the cleaning effect.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
