[0073] The present invention is further described with reference to the following examples.

[0074] Example 1.

[0075] like Figure 1-5 As shown, a cow dung separation and purification treatment system includes a filtering and blocking mechanism, which is connected to a separation and mixing tank 2 through a first sewage pump 1, and the discharge port of the separation and mixing tank 2 is connected to an automatic salvage slurry storage tank 3. An automatic salvage mechanism is provided inside the automatic salvage slurry storage tank 3, and a second sewage pump 4 is installed inside the automatic salvage slurry storage tank 3. The output end of the second sewage pump 4 is connected to a dry-wet separator 5.

[0076] The present application is used to separate and purify cow dung. First, the cow dung is put into a filtering and blocking mechanism for filtration, the debris is removed and a small amount of water is added to form a cow dung slurry. The filtered cow dung enters the separation and stirring tank 2. The stirring tube is mainly used to mix the cow dung with water and break the connecting bonds of the separated cow dung colloid to form a mixed solution. The mixed solution is allowed to stand and stratify in the automatic salvage slurry storage tank 3. After stratification, it is salvaged and discharged layer by layer through the automatic salvage mechanism. The dry-wet separator 5 is used to separate the cow dung fiber solution into dry and wet parts and recycle the cow dung fiber.

[0077] The automatic salvage slurry storage tank 3 is rectangular and is provided with a cleaning drive end 6 and a discharge end 7. The automatic salvage mechanism includes an equipment positioning platform 8 fixedly installed on the cleaning drive end 6. Two parallel sliding rails 9 are fixedly installed on the automatic salvage slurry storage tank 3 between the cleaning drive end 6 and the discharge end 7. Slide blocks 10 are installed on the two sliding rails 9. The two slide blocks 10 are fixedly connected by a force transmission positioning plate 11. A driving block 12 is fixedly installed on any one of the slide blocks 10. A driving motor 13 is fixedly installed on the equipment positioning platform 8. A first transmission screw 14 is fixedly installed on the output end of the driving motor 13. The first transmission screw 14 spirally passes through the driving block 12. The other end of the first transmission screw 14 is rotatably installed on the limit plate 15 that limits the sliding rail 9. An organic matter salvage component is installed on the force transmission positioning plate 11.

[0078] The two ends of the automatic salvage pulp storage tank 3 in the length direction are the cleaning drive end 6 and the discharge end 7 respectively. The equipment positioning platform 8 is used to carry the driving equipment. The output of the driving motor 13 drives the rotation of the first transmission screw 14, and then drives the driving block 12 that is spirally matched with it to produce a linear displacement. Then, the displacement of the driving block 12 drives the two sliders 10 and the force transmission positioning plate 11 to move on the sliding track 9, realizing the movement along the length direction of the automatic salvage pulp storage tank 3. The mixed solution of cow dung and water will form three layers when it is left to stand inside the automatic salvage pulp storage tank 3, with an organic matter layer on the top, a fiber solution layer in the middle, and a lignin layer at the bottom. The organic matter layer is scraped, discharged, and collected by the organic matter salvage component installed on the force transmission positioning plate 11.

[0079] The organic matter salvage assembly includes a bent positioning plate 16 fixedly mounted above the force transmission positioning plate 11, on which a salvage height adjustment screw 17 is rotatably mounted, and the bottom of the salvage height adjustment screw 17 is rotatably engaged with the force transmission positioning plate 11, and a movable through hole 18 is opened on the force transmission positioning plate 11, and a salvage scraper 19 is movably mounted inside the movable through hole 18, and a salvage transmission block 20 is fixedly mounted on the top of the salvage scraper 19, and the salvage transmission block 20 is spirally engaged with the salvage height adjustment screw 17.

[0080] The organic matter salvage assembly drives the salvage transmission block 20 to rise and fall by rotating the salvage height adjustment screw 17, thereby driving the salvage scraper 19 to rise and fall. When the organic matter layer needs to be salvaged, the bottom height of the salvage scraper 19 is adjusted to the same height as the bottom height of the organic matter layer. The width of the salvage scraper 19 is the same as the inner width of the automatic salvage slurry storage tank 3. In the process of moving the salvage scraper 19 from the cleaning drive end 6 to the discharge end 7, it pushes the organic matter layer to move toward the discharge end 7, and then the discharge end 7 salvages and discharges the organic matter.

[0081] The discharge end 7 is provided with a discharge slot 21, on which a discharge adjustment assembly is installed. The discharge adjustment assembly includes a positioning transverse plate 22 fixedly mounted on the top of the discharge slot 21, and a discharge height adjustment screw 23 is simultaneously rotatably mounted on the positioning transverse plate 22 and the bottom of the discharge slot 21. A lifting valve plate 24 is vertically movably mounted on the discharge slot 21, and a discharge transmission block 25 is fixedly mounted on the lifting valve plate 24. The discharge transmission block 25 is spirally engaged with the discharge height adjustment screw 23.

[0082] The discharge end 7 adjusts the height of the lifting valve plate 24 through the discharge adjustment component, and the discharge transmission block 25 is driven to rise and fall by rotating the discharge height adjustment screw 23, thereby driving the lifting valve plate 24 to rise and fall inside the discharge slot 21 to achieve the adjustment of the height of the discharge slot 21. When it is necessary to salvage and discharge organic matter, the top height of the lifting valve plate 24 is adjusted to the same height as the bottom height of the organic matter layer, and the salvage scraper 19 is used to discharge the organic matter. A movable drainage trough can be installed at the discharge slot 21 to collect and organize the organic matter.

[0083] Corresponding inner movable grooves 26 and outer movable grooves 27 are provided on the side walls of the automatic salvage slurry storage tank 3 near the discharge end 7. An inner adjusting rod 28 and an outer adjusting rod 29 are movably installed on the inner movable groove 26 and the outer movable groove 27 respectively. The inner adjusting rod 28 and the outer adjusting rod 29 are connected by an adjusting connecting rod 30. An equipment base 31 is fixedly installed on the inner adjusting rod 28, and a second sewage pump 4 is fixedly installed on the equipment base 31. A plurality of threaded through holes 32 are evenly provided in the longitudinal direction on the outer adjusting rod 29, and a positioning screw hole 33 is provided on the outer movable groove 27. The positioning screw hole 33 and any one of the threaded through holes 32 are locked and matched by a positioning bolt 34.

[0084] An adjusting handle is installed on the outer adjusting rod 29. The inner adjusting rod 28, the outer adjusting rod 29 and the adjusting connecting rod 30 are raised or lowered by the adjusting handle, thereby driving the equipment base 31 and the second sewage pump 4 to rise and fall to adapt to different heights, so that the water inlet of the second sewage pump 4 is located in the middle fiber solution layer, and the fiber solution is pumped into the interior of the dry-wet separator 5. At the same time, any one of the threaded through holes 32 and the positioning screw hole 33 are screwed locked at the same time by the positioning bolt 34 to achieve height locking of the second sewage pump 4.

[0085] A multi-nozzle sprayer 35 is also fixedly mounted on the force transmission positioning plate 11 , and the multi-nozzle sprayer 35 is connected to a liquid storage tank 37 outside the automatic salvage slurry storage tank 3 through a telescopic hose 36 . A transfer positioning ring 38 is fixedly mounted on the drive block 12 , and the telescopic hose 36 is fixedly passed through the transfer positioning ring 38 .

[0086] Deodorant is loaded into the liquid storage tank 37 and pumped to the multi-nozzle sprayer 35 through the telescopic hose 36. The driving motor 13 drives the force transmission positioning plate 11 to move, thereby driving the entire multi-nozzle sprayer 35 to move along the length direction of the automatic salvage slurry storage tank 3 to spray the deodorant and avoid odor pollution to the environment.

[0087] The filtering and trash-blocking mechanism includes a mesh trash rack 39 , a collection box 40 is fixedly mounted on the bottom of the mesh trash rack 39 , and the interior of the collection box 40 is connected to the feed port of the separation and mixing tank 2 through the first sewage pump 1 .

[0088] A drain valve 41 is installed at the bottom of the automatic salvage slurry storage tank 3 .

[0089] The filtering and blocking mechanism filters impurities through the mesh trash rack 39 and pumps the cow dung into the separation and mixing tank 2 through the first sewage pump 1 inside the collecting box 40 .

[0090] The drain valve 41 is located at the bottom of the automatic salvage pulp storage tank 3 and can cooperate with the salvage scraper 19 to discharge the lignin.

[0091] A cow dung separation and purification process comprises the following steps:

[0092] S1: Filter and remove impurities, pour fresh cow dung into the mesh trash rack 39 to filter out impurities, and add water to the fresh cow dung to form cow dung slurry;

[0093] The trash rack 39 can be made into multiple layers, with a pore size of 10 cm, a pore size of 5 cm and a pore size of 1 cm.

[0094] S2: colloid production, the cow dung slurry is pumped into the interior of the separation and stirring tank 2 through the first sewage pump 1, and water is added again to obtain cow dung colloid;

[0095] A ten cubic meter drum-type separation mixing tank 2 is filled with six cubic meters of cow dung and three cubic meters of water.

[0096] S3: stirring and separating, starting the separation stirring tank 2 and adding kaolin and zeolite powder into the separation stirring tank 2 to obtain a cow dung bond-breaking mixed solution and adding the solution to the automatic salvage slurry storage tank 3;

[0097] Start the separation stirring tank 2, add kaolin and zeolite powder, the role of these two substances is to destroy the molecular connection bonds in the cow dung colloid, forming a mixed solution, making the cow dung solution easier to stratify. After stirring for fifteen minutes, the cow dung slurry is injected into the cow dung slurry storage tank.

[0098] S4: standing and stratifying, wherein the cow dung bond-breaking mixed solution is allowed to stand, so that the cow dung bond-breaking mixed solution forms a cow dung bond-breaking stratified solution having an organic matter layer, a fiber solution layer, and a lignin layer from top to bottom;

[0099] After losing the bond connection, the original cow dung fiber becomes suspended fiber dissolved in water, and the other substances return to the natural physical properties of their respective components. Among them, the organic matter has a light specific gravity and is suspended in the water layer. The fiber is suspended in the water. The lignin has a large specific gravity and settles down. Kaolin and zeolite powder are the first to settle to the bottom layer. The dissolved anions and cations are also separated from other substances. In this process, different solutes at different dissolution levels are treated with different methods. That is, the organic matter layer at the top is treated with probiotic deodorant spray, and the odor-eating bacteria capture the organic odor.

[0100] S5: Salvage the organic layer. Adjust the bottom height of the salvage scraper 19 to the same height as the bottom of the organic layer. Start the drive motor 13 to drive the salvage scraper 19 and cooperate with the lifting valve plate 24 to scrape and salvage the organic layer.

[0101] S6: Collect the fiber solution, adjust the height of the second sewage pump 4 to the fiber solution layer, and pump the fiber solution into the dry-wet separator 5;

[0102] S7: Drain the lignin. Adjust the bottom height of the salvage scraper 19 to the same height as the bottom of the automatic salvage pulp storage tank 3. Start the drive motor 13 to drive the salvage scraper 19. Open the drain valve 41 to drain the lignin.

[0103] The precipitated lignin is also used for biofuel production.

[0104] S8: extracting cow dung fibers, starting the dry-wet separator 5, performing dry-wet separation on the cow dung fiber mixed solution to obtain cow dung fibers.

[0105] In the mixed solution, the fiber-containing substances are screened out into pure fiber materials using dry-wet separators of different particle sizes. Particles with a mesh size of 10 or above are used for biofuel production, those with a mesh size of 10 to 80 are used for organic soil as a matrix soil, and those with a mesh size of 80 to 200 are used for paper pulp.
