Description

Technical Field

[0001] The utility model relates to the field of seedling cultivation, in particular to a modifier release device and a seedling cultivation system. Background Technique

[0002] In some areas of Xinjiang, China, due to extremely little rainfall, arid climate, and relatively high temperature, water is easy to evaporate, and salts rise to the ground surface with capillary water, accumulating over time to form saline-alkali land. At the same time, with the aggravation of land salinization, accompanying ecological problems such as soil desertification are becoming increasingly prominent. Existing methods for treating saline-alkali land often have certain problems, and there is an urgent need to seek more complete ways to treat saline-alkali land and restore soil fertility.

[0003] Chinese patent application with publication number CN107879422A discloses a new type of water ecological cycle system. The qualified water treated by domestic sewage treatment equipment, industrial sewage treatment equipment and hazardous waste treatment equipment is sent to the sewage treatment and regeneration equipment through a river channel or directly. The treated reclaimed water meets the industrial water standard and is supplied for industrial enterprises to use in production, circulating cooling water, etc. Hazardous waste and sludge generated during the production process of industrial enterprises are harmlessly treated in the sludge and hazardous waste harmless treatment equipment. The concentrated brine generated during the sewage regeneration process of the sewage treatment and regeneration equipment is discharged to the wetland for natural degradation after being treated by ozone + catalytic oxidation, and then flows into the ocean. The sludge generated by the domestic sewage treatment equipment is produced into an in-situ modifier for saline-alkali land original soil in the sludge composting equipment and applied to the in-situ improvement of saline-alkali land original soil together with part of the reclaimed water. In this scheme, sludge composting is carried out on the surface of saline-alkali land, and the effect of single sludge composting is often poor. Content of the Utility Model

[0004] The utility model aims to provide a modifier release device, which can be used to display the content of substances in a non-transparent storage bin.

[0005] The utility model also provides a seedling cultivation system, which can be used for treating saline-alkali land to ensure the treatment effect of saline-alkali land.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A modifier release device includes a storage bin. A drain port is opened at the bottom of the storage bin, and a plurality of spring telescopic legs are installed at the bottom of the storage bin;

[0008] The spring telescopic leg includes a spring and two mutually sleeved outer shells installed outside the spring.

[0009] The modifier release device includes a storage bin, which is connected to telescopic legs. There is a spring inside the telescopic legs. Under the action of gravity, the telescopic legs will change, thereby indicating the content of the material in the storage bin. The water content in the storage bin is determined by the height of the storage bin to determine whether the storage bin needs to be replaced. At the same time, the telescopic legs can support the storage bin to make it stable.

[0010] In one preferred embodiment, the outside of the storage bin is covered with a sealed heat-insulating layer, which is suitable for application in high-temperature saline-alkali sandy soil.

[0011] The present utility model also discloses a seedling cultivation system, which includes a plurality of isolation membranes. The bottoms of the isolation membranes are punched with holes, and the isolation membranes are filled with layered pressed cakes. Pipes are connected between the holes, and the water inlet of the pipe is connected to the above-mentioned modifier release device, or the drain outlet of the modifier release device is installed directly above the water inlet.

[0012] The pipe is connected between each isolation membrane and can provide moisture for the layered pressed cakes in each isolation membrane.

[0013] In one preferred embodiment, the pipe includes a main pipe and a water inlet opened on the main pipe. The main pipe is communicated with a plurality of branch pipes through an inflection connecting pipe.

[0014] By adjusting the installation height of the main pipe to be higher than that of the branch pipes, it is convenient for the modifier to be evenly distributed under the action of gravity.

[0015] In one preferred embodiment, the installation height from the water inlet end to the other end of the pipe decreases in sequence.

[0016] Water can flow by gravity to every place, and at the same time, the situation of excessive local water is reduced.

[0017] In one preferred embodiment, the pipe diameter from the end of the main pipe near the water inlet to the other end of the pipe decreases in sequence.

[0018] Water can flow by gravity to every place, and at the same time, the situation of excessive local water is reduced.

[0019] Compared with the prior art, the beneficial effects of the present utility model are:

[0020] 1. Compared with laying longer and larger-diameter irrigation water transportation pipes, the present utility model is equipped with a modifier storage tank (which can also hold water) and smaller-diameter pipes, which not only saves the investment in laying pipes, but also avoids waste of water during pipeline water transportation, and the water consumption will be greatly reduced.

[0021] 2. Configure a modifier storage tank. The present utility model can provide different modifiers according to different types and degrees of saline-alkali land, and can adjust the modifier concentration at any time according to the growth conditions of plants, reducing the treatment cost.

[0022] 3. Configure a seedling cultivation system. Compared with directly planting salt-tolerant plants in saline-alkali land, the survival efficiency of plants is improved. And a membrane system is configured, which is not only convenient for laying, but also reduces water evaporation. Moreover, compared with the current square-shaped plant planting, the present utility model is configured in a honeycomb shape, which can reduce the tearing of the plant area by sand and wind in areas with relatively serious desertification such as Xinjiang, with higher stability and further improving the efficiency of saline-alkali land treatment.

[0040] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments. It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. For the sake of convenience of description, words such as "upper", "lower", "left", and "right" hereinafter only indicate the same directions as the upper, lower, left, and right directions of the drawings themselves, and do not limit the structure

[0041] Such as Figures 1-4As shown in the figure, the conditioner release device 16 includes a storage bin 9.16.1, spring telescopic legs 9.16.2, a support round opening 9.16.3, and a drain port 9.16.4. The conditioner release device 16 can not only hold conditioners but also hold water. The outside of the storage bin 9.16.1 is covered with a closed heat-insulating layer. There is a spring inside the spring telescopic legs 9.16.2. When there is more moisture, the storage bin 9.16.1 is heavier and the spring telescopic legs 9.16.2 become shorter. When there is less moisture, the storage bin 9.16.1 is lighter and the spring telescopic legs 9.16.2 become longer. Therefore, it is possible to judge whether water needs to be added according to the length of the spring telescopic legs 9.16.2, and the way to add water is to directly replace the conditioner release device 16.

[0042] Figure 5 It is a schematic structural diagram of a seedling cultivation system in an embodiment of the present invention. A seedling cultivation system includes a plurality of isolation membranes 9.5. The isolation membranes 9.5 are filled with layered pressed cakes 17. The bottom of the isolation membranes 9.5 is perforated, and pipes 9.4 are connected between the holes. As Figure 6 shown, the water inlet 9.4.1 of the pipe 9.4 is connected to the conditioner release device 16, or the drain port of the conditioner release device 16 is installed directly above the water inlet 9.4.1. The pipe 9.4 includes a main pipe 9.4.2 and a water inlet 9.4.1 provided on the main pipe 9.4.2. The main pipe 9.4.2 is connected to a plurality of branch pipes 9.4.3 through an inflection point connecting pipe 9.4.4.

[0043] Plants that can control saline-alkali land, such as Suaeda glauca, etc., are planted on the seedling cultivation system 14. However, considering that the land to be treated is extremely dry and there are problems with sandstorms, a few windbreak and sand-fixation plants, such as Haloxylon ammodendron, etc., can be selected and planted in each isolation membrane 9.5.

[0044] The plant pots cultivated by the seedling cultivation system 14 are transplanted to the saline-alkali land sand 10 to be treated respectively. The water in the water outlet temporary storage facility 2 is placed in the storage bin 9.16.1 through the support round opening 9.16.3 of the conditioner release device 16, transported to the saline-alkali land sand 10 to be treated by vehicle, and then inserted upside down into the drain port 9.16.4 to provide water source for plant growth.

[0045] If an extreme situation occurs and the degree of land salinization is extremely high and plants are difficult to survive, then the conditioner release device 16 is filled with liquid conditioner, and then inserted upside down into the drain port 9.16.4 to quickly reduce the degree of land salinization by chemical methods, and then seedlings are planted to further adsorb and transfer the salt in the soil.

[0046] As Figures 7-14As shown in the figure, in this embodiment, the seedling cultivation system can be prepared by using a layered cake pressing system 9. The layered cake pressing system 9 includes a bottom plate 9.1, a frame 9.2, a punching cone 9.3, a pipeline 9.4, and an isolation film 9.5. The punching cone 9.3 is opened on the bottom plate 9.1. The frame 9.2 is an integral formed by connecting multiple honeycomb-shaped frames, including a solid hole 9.2.1 and multiple hollow holes 9.2.2 (as Figure 9 shown), as Figure 14 shown, and the relevant usage steps are as follows:

[0047] Place the bottom plate 9.1 on the ground of the compost plant, place the frame 9.2 on the bottom plate 9.1, place the isolation film 9.5 in each hollow hole 9.2.2, then spread the ash residue in the ash residue temporary storage system 13 on the layered cake pressing system 9, and then compact it. Then spread the organic fertilizer produced by the composting system 8 on the layered cake pressing system 9, and then compact it to form the seedling cultivation system 14.

[0048] Take out the frame 9.2, lay the pipeline 9.4 in the seedling cultivation system 14. The pipeline 9.4 is higher at the end of the solid hole 9.2.1 and descends in a stepped manner along with the pipeline derivation. As Figure 6 shown, the pipeline 9.4 includes a water inlet 9.4.1, a main pipe 9.4.2, a branch pipe 9.4.3, and an inflection point connecting pipe 9.4.4.

[0049] As Figure 15 shown, the modifier release device 16 and the seedling cultivation system 14 in the present invention can be used in a saline-alkali land improvement system. The saline-alkali land improvement system further includes a sewage treatment system 1, an effluent temporary storage facility 2, a surplus sludge temporary storage facility 3, a sludge thickening facility 4, an other easily degradable organic solid waste temporary storage facility 5, a sludge mixing device 6, a mixing facility 7, a composting system 8, a layered cake pressing system 9, saline-alkali land sand to be treated 10, a plant temporary storage facility 11, a formed fuel processing system 12, an ash residue temporary storage system 13, and a heating system 15.

[0050] In this embodiment, the sewage treatment system 1 is respectively connected to the effluent temporary storage facility 2, the surplus sludge temporary storage facility 3, the sludge mixing device 6, and the sludge thickening facility 4. The sewage treatment system 1 treats municipal sewage. The treated reclaimed water is temporarily stored in the effluent temporary storage facility 2, and the generated sludge, surplus sludge, is stored in the surplus sludge temporary storage facility 3. The sewage treatment system 1 includes a sludge reflux process. This time, 10-20% of the reflux sludge is considered to enter the sludge mixing device 6, and the rest is directly refluxed to supplement sludge for the sewage treatment system 1.

[0051] In this embodiment, the configured excess sludge temporary storage facility 3 is respectively connected to the sludge thickening facility 4 and the plant temporary storage facility 11. A part of the excess sludge flows from the excess sludge temporary storage facility 3 to the sludge thickening facility 4 for gravity thickening. The supernatant flows to the sewage treatment system 1 for treatment, and the lower concentrated sludge flows to the mixing facility 7. The plant temporary storage facility 11 crushes the dead plants in the saline-alkali land collected, adds another part of the excess sludge, and the excess sludge generates adhesiveness. After mixing in the formed fuel processing system 12, it is pressed and dried to form formed fuel.

[0052] In this embodiment, the configured effluent temporary storage facility 2 is respectively connected to the seedling cultivation system 14 and the saline-alkali land sand 10 to be treated. The effluent temporary storage facility 2 provides the water required for plant growth for the seedling cultivation system 14. After the seedling cultivation system 14 is transplanted to the saline-alkali land to be treated, it provides water for the saline-alkali land sand 10 to be treated.

[0053] In this embodiment, the mixing facility 7 is respectively connected to the sludge thickening facility 4 and the sludge mixing device 6. Its main function is to uniformly mix the concentrated sludge and the reflux sedimentation sludge.

[0054] In this embodiment, the composting system 8 is respectively connected to the mixing facility 7, the other easily degradable organic solid waste temporary storage facility 5, the layered cake pressing system 9, the ash residue temporary storage system 13, and the heating system 15. The mixing facility 7 provides the uniformly mixed sludge for the composting system 8. The other easily degradable organic solid waste temporary storage facility 5 provides organic solid wastes such as livestock and poultry manure and food waste for the composting system 8. If there is no such part of solid waste on site, it can also not be provided. The ash residue temporary storage system 13 provides the ash residue generated after the formed fuel is burned for the composting system 8. Organic fertilizer is generated after the excess sludge, other easily degradable organic solid wastes, and ash residue are composted. When the temperature is relatively low, the heating system 15 provides heat for the composting system 8.

[0055] In this embodiment, the configured layered cake pressing system 9 is respectively connected to the seedling cultivation system 14, the ash residue temporary storage system 13, the composting system 8, and the other easily degradable organic solid waste temporary storage facility 5. The ash residue temporary storage system 13 provides ash residue for the layered cake pressing system 9. The composting system 8 provides organic fertilizer for the layered cake pressing system 9, and the other easily degradable organic solid waste temporary storage facility 5 provides other organic matters for the layered cake pressing system 9.

[0056] This saline-alkali land improvement system combines the treatment of solid wastes such as sludge, other organic solid wastes, and ash residue with the treatment of saline-alkali land in desert areas. At the same time, it is equipped with a layered cake pressing system and a modifier release device, and corresponding pipeline facilities are configured to meet the needs of treating saline-alkali land, effectively overcoming the disadvantages of high cost and difficult operation of general treatment processes, and at the same time solving the problem that the system is difficult to be stable during the treatment process.

[0057] In this embodiment, the formed fuel processing system 12 is respectively connected to the plant temporary storage facility 11, the heating system 15, and the ash residue temporary storage system 13. The plant temporary storage facility 11 provides raw materials for the formed fuel processing system 12. When the formed raw materials are used, they provide heat sources for the heating system, and at the same time, the generated ash residues are temporarily stored in the ash residue temporary storage system 13.

[0058] The content clarified in the above embodiments should be understood that these embodiments are only used to more clearly illustrate the present invention, rather than to limit the scope of the present invention. After reading the present invention, various equivalent forms of modification of this embodiment by those skilled in the art all fall within the scope defined by the appended claims of the present invention.
