Description

Technical Field

[0001] The utility model relates to the field of sludge recovery, in particular to a layered cake pressing system and a seedling cultivation system. Background Art

[0002] In some parts of Xinjiang, China, due to extremely little rainfall, arid climate, and relatively high temperature, water is prone to evaporation, and salts rise to the surface with capillary water, accumulating over time to form saline-alkali land. At the same time, with the aggravation of land salinization, associated ecological problems such as soil desertification have become increasingly prominent. Existing methods for treating saline-alkali land often have certain problems, and there is an urgent need to seek more complete methods 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 recycled water meets the industrial water standard and is supplied for industrial enterprises' production water, 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 a 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 soil conditioner for saline-alkali land in a sludge composting equipment, and is applied to the in-situ improvement of saline-alkali land together with part of the recycled water. In this scheme, sludge composting is carried out on the surface of saline-alkali land, and the sludge is easily blown away by wind and sand, and the effect of single sludge composting is often poor. Content of the Utility Model

[0004] The utility model aims to provide a layered cake pressing system and a seedling cultivation system for preparing cakes for treating saline-alkali land, which are not easily blown away by wind and sand and can ensure the treatment effect of saline-alkali land.

[0005] In order to achieve the above object, the technical solution adopted by the utility model is:

[0006] A layered cake pressing system, the layered cake pressing system includes a bottom plate, a frame is placed on the upper surface of the bottom plate, the frame includes a plurality of hollow holes with openings at both upper and lower ends, a plurality of punching cones are fixed on the upper surface of the bottom plate, and the plurality of punching cones are respectively located in the plurality of hollow holes. An isolation film is laid in the hollow holes, and the isolation film is punched through the punching cones.

[0007] The isolation film is placed inside the frame and punctured by a punching cone on the bottom plate to form a hole. Subsequently, cinder, organic fertilizer, sandy soil, sludge, etc. are spread flat in the isolation film and compacted to form a layered pressed cake. Plants are planted in the layered pressed cake, and the roots of the plants grow on the saline-alkali land through this hole, adsorbing the salts in the saline-alkali land.

[0008] The isolation film can adopt the flowerpot film sleeve in the patent application with the publication number of CN103026913A, which is convenient for the subsequent separation of the layered pressed cake from the frame.

[0009] In one preferred embodiment, the hollow hole is hexagonal.

[0010] Multiple hexagonal hollow holes are combined together to form a honeycomb shape.

[0011] In one preferred embodiment, the frame further includes a solid hole.

[0012] A solid hole is set without filling the layered pressed cake, and this area is subsequently used to install the water inlet for laying pipelines.

[0013] The present utility model also discloses a seedling cultivation system prepared by the above-mentioned layered pressed cake system, which includes a plurality of isolation films. The bottoms of the isolation films are punched with holes, and the isolation films are filled with layered pressed cakes. Pipelines are connected between the holes.

[0014] The pipelines are connected between the isolation films and can provide water for the layered pressed cakes in each isolation film.

[0015] In one preferred embodiment, the pipeline 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 inflection connecting pipes.

[0016] The installation height of the main pipe is higher than that of the branch pipes, which is convenient for the uniform distribution of the conditioner under the action of gravity.

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

[0020] Water can flow by gravity to every place, and at the same time, the situation of excessive local water is reduced.

[0021] In one preferred embodiment, a modifier temporary storage facility is connected to the water inlet, or the drain outlet of the modifier temporary storage facility is installed directly above the water inlet.

[0022] In one preferred embodiment, the modifier temporary storage facility includes a storage bin. A drain outlet is formed at the bottom of the storage bin. The drain outlet is communicated with the water inlet, or the drain outlet is installed directly above the water inlet. A plurality of spring telescopic legs are installed at the bottom of the storage bin.

[0023] The modifier temporary storage facility includes a storage bin. The storage bin is connected with telescopic legs. There is a spring inside the telescopic legs. Under the action of gravity, the telescopic legs will change, so as to show the content of the substance 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.

[0024] In addition, if an extreme situation occurs where the degree of soil salinization is extremely high and plants are difficult to survive, the modifier temporary storage facility is filled with liquid modifier, and then it is inserted upside down into the drain outlet. The modifier flows through the pipeline to each isolation membrane, and then flows to the land through the holes on the isolation membrane, quickly reducing the degree of soil salinization by chemical methods, and then planting seedlings to ensure the effect of saline-alkali land treatment.

[0025] In one preferred embodiment, the spring telescopic leg includes a spring and two mutually sleeved outer shells installed outside the spring.

[0026] The layered cake pressing system provides organic fertilizer and moisture for the seedling cultivation system.

[0027] The isolation membrane is placed in a frame and is punctured by a punching cone on the bottom plate to form a hole. The roots of the planted plants grow on the saline-alkali land through this hole and adsorb the salt of the saline-alkali land.

[0028] The pipeline is connected between each isolation membrane, can provide moisture for each isolation membrane, and its height decreases horizontally. The moisture can flow by gravity without the need to provide additional power, and the moisture distribution will be more uniform.

[0029] The improver temporary storage facility 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 showing the content of the material in the storage bin. At the same time, the telescopic legs can support the storage bin to make it stable. The outside of the storage bin is covered with a closed heat-insulating layer, which can reduce the evaporation of water and save water resources. In addition, if an extreme situation occurs where the degree of soil salinization is extremely high and it is difficult for plants to survive, the improver temporary storage facility is filled with liquid improver, and then inserted upside down into the drain outlet. The improver flows through the pipeline to each isolation membrane, and then flows through the holes on the isolation membrane to the land, quickly reducing the degree of soil salinization by chemical methods. Then, seedlings are planted to ensure the effect of saline-alkali land treatment.

[0030] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0031] 1. The layered cake pressing system in the present utility model can lay and compact sludge, ash residue, organic fertilizer, sandy soil, etc. as needed, increasing the density so that it is not easily blown away by wind and sand, and making a combination according to the nutrients required by plants to ensure the effect of saline-alkali land treatment.

[0032] 2. Compared with laying longer and larger-diameter irrigation water transportation pipelines, the present utility model is equipped with an improver storage tank (which can also hold water) and smaller-diameter pipelines, not only saving the investment in laying pipelines, but also avoiding waste of water during pipeline transportation, and greatly reducing the water consumption.

[0033] 3. Equipped with an improver storage tank, the present utility model can provide different improvers according to different types and degrees of saline-alkali land, and can adjust the improver concentration at any time according to the growth situation of plants, reducing the treatment cost.

[0034] 4. Equipped with a seedling cultivation system, compared with directly planting salt-tolerant plants in saline-alkali land, it improves the survival efficiency of plants, and is equipped with an isolation membrane system, 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 plants by wind and sand in areas with relatively serious desertification such as Xinjiang, with higher stability, and further improve the efficiency of saline-alkali land treatment.

Detailed implementation manners

[0052] The present utility model will be described in detail below with reference to the drawings and in combination 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 convenience of narration, 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.

[0053] As Figure 1-8 shown, in this embodiment, the configured stratified 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 body formed by connecting a plurality of honeycomb-shaped frames, including a solid hole 9.2.1 and a plurality of hollow holes 9.2.2 (as Figure 2 shown), as Figure 8 shown, the relevant usage steps are as follows:

[0054] 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 on the stratified cake pressing system 9, and then compact it. Then spread the organic fertilizer on the stratified cake pressing system 9, and then compact it to form the seedling cultivation system 14, as Figure 9 shown.

[0055] 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 away from the solid hole 9.2.1 and descends step by step along with the extension of the pipeline. As Figure 10 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.

[0056] As Figure 11-14As shown in the figure, the modifier temporary storage facility 16 includes a storage bin 9.16.1, a spring telescopic leg 9.16.2, a support round opening 9.16.3, and a drain outlet 9.16.4. The modifier temporary storage facility 16 can not only store modifiers but also store 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 leg 9.16.2. When there is more moisture, the storage bin 9.16.1 is heavier and the spring telescopic leg 9.16.2 becomes shorter. When there is less moisture, the storage bin 9.16.1 is lighter and the spring telescopic leg 9.16.2 becomes longer. Therefore, it is possible to judge whether water needs to be added according to the length of the spring telescopic leg 9.16.2, and the way to add water is to directly replace the modifier temporary storage facility 16.

[0057] Plants that can treat saline-alkali land, such as Suaeda glauca, etc., are planted on the seedling cultivation system 14. However, considering that the treated land is extremely dry and there are problems with sandstorms, several windbreak and sand-fixing plants, such as Haloxylon ammodendron, etc., can be selected from each isolation film 9.5 for planting.

[0058] 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 from the water outlet temporary storage facility 2 is stored in the storage bin 9.16.1 through the support round opening 9.16.3 of the modifier temporary storage facility 16, transported to the saline-alkali land sand 10 to be treated by vehicle, and then inserted upside down into the drain outlet 9.16.4 to provide water source for plant growth.

[0059] If extreme situations occur and the degree of land salinization is extremely high and plants are difficult to survive, then the modifier temporary storage facility 16 is filled with liquid modifier, and then inserted upside down into the drain outlet 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.

[0060] As Figure 15 As shown in the figure, the layered cake pressing system 9 and the seedling cultivation system 14 in the present utility model can be used in a saline-alkali land improvement system. The saline-alkali land improvement system includes a sewage treatment system 1, a water outlet temporary storage facility 2, a surplus sludge temporary storage facility 3, a sludge thickening facility 4, other easily degradable organic solid waste temporary storage facilities 5, a sludge mixing device 6, a mixing facility 7, a composting system 8, a layered cake pressing system 9, the saline-alkali land sand 10 to be treated, a plant temporary storage facility 11, a formed fuel processing system 12, a slag temporary storage system 13, a seedling cultivation system 14, a heating system 15, and a modifier temporary storage facility 16.

[0061] In this embodiment, the sewage treatment system 1 is respectively connected to the effluent temporary storage facility 2, the excess 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 meets the standards and is temporarily stored in the effluent temporary storage facility 2. The generated excess sludge is stored in the excess sludge temporary storage facility 3. The sewage treatment system 1 includes a sludge return process. This time, 10-20% of the returned sludge is fed into the sludge mixing device 6, and the rest is directly returned to supplement the sludge for the sewage treatment system 1.

[0062] 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.

[0063] 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.

[0064] 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 returned sediment sludge.

[0065] 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 kitchen 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. The excess sludge, other easily degradable organic solid wastes, and ash residues are composted to produce organic fertilizers. When the temperature is relatively low, the heating system 15 provides heat sources for the composting system 8.

[0066] In this embodiment, the hierarchical briquetting system 9 is respectively connected to the seedling cultivation system 14, the ash residue temporary storage system 13, the composting system 8, and other temporary storage facilities 5 for easily degradable organic solid waste. The ash residue temporary storage system 13 provides ash residue for the hierarchical briquetting system 9, the composting system 8 provides organic fertilizer for the hierarchical briquetting system 9, and other temporary storage facilities 5 for easily degradable organic solid waste provide other organic matters for the hierarchical briquetting system 9.

[0067] This saline-alkali land improvement system combines the treatment of solid wastes such as sludge, other organic solid wastes, and ash residues with the treatment of saline-alkali land in desert areas. At the same time, it is equipped with a hierarchical briquetting system and a temporary storage facility for the modifier, 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 of the instability of the system during the treatment process.

[0068] 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.
