Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a sewage treatment filtering device based on a farm. Background Technique

[0002] When livestock are raised, in order to reduce the prevalence rate of livestock and improve the hygiene of the farm, the inside of the farm is cleaned regularly, resulting in a large amount of farm sewage generated every day.

[0003] Farm sewage mainly includes animal urine, some animal feces and flushing water for the breeding shed. The farm sewage not only contains suspended solids and ammonia nitrogen content, but also contains a large number of pathogenic microorganisms. Therefore, in existing patents, for example, a sewage treatment device applicable to farms with the application number CN202122288610.4 discloses a box body, and a water inlet pipe is arranged at the top of the box body, and a spiral blade is arranged inside the box body. For the sewage treatment device applicable to farms, since the sewage from the farm contains animal excrement, before treatment, the solid excrement is first conveyed to the aggregate box by the spiral blade for convenient manual reprocessing or direct discharge. The sewage flows to the lower part through the first filter holes for filtration treatment, playing a role in solid-liquid separation. The blades on the surface of the stirring roller can, on the one hand, crush the impurity particles contained in the sewage, and on the other hand, enable the chemical agent to be fully integrated with the sewage to remove harmful substances in the sewage. Finally, the treated sewage is pumped into the box body again by a water pump, which can, on the one hand, clean the inside of the box body, and on the other hand, filter the sewage multiple times to improve the sewage treatment efficiency.

[0004] In the above patent, although the feces and solid impurities in the sewage can be filtered out and crushed to improve the storage quantity, there are still certain defects. Since the feces and solid impurities themselves have a certain water absorption capacity, a large amount of water will be contained in the feces and solid impurities and remain in a wet state, resulting in fluidity. If the internal water is not removed, when the storage area of the feces and solid impurities is cleaned, the accumulated feces and solid impurities will flow out of the storage space when opened, which will not only increase the cleaning difficulty of the staff, but also cause pollution to the surrounding environment.

[0005] Therefore, how to provide a sewage treatment filtering device based on a farm is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0033] The following describes the specific implementation of the present utility model in detail with reference to specific embodiments.

[0034] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a structure diagram of a sewage treatment and filtration device for a farm provided by an embodiment of the present utility model includes;

[0035] Treatment tank 1:

[0036] Partition board 20, the partition board 20 is arranged at the right end of the treatment tank 1, the left side of the partition board 20 is set as the sewage area, and the right side of the partition board 20 is set as the temporary storage area;

[0038] A movable flap 3, which is movably placed inside the delivery port 2 and opened by force to reduce the outflow of odor;

[0039] A solid-liquid separation plate 4, which is fixedly mounted on the upper side of the left end of the processing box 1 to filter and guide the movement of impurities;

[0040] The extrusion structure is symmetrically arranged inside the processing box 1, and penetrates the surface of the partition 20 to enter the temporary storage area.

[0041] In the embodiment of the utility model, when in use, the farm sewage will enter through the inlet 2 on the top left side of the treatment box 1, and push open the movable flap 3 to enter the interior of the left side of the treatment box 1, and contact the solid-liquid separation plate 4, so that the feces and solid impurities in the farm sewage will be intercepted by the solid-liquid separation plate 4 and move to the front and rear sides, and then the extrusion structure will be started to receive the feces and solid impurities falling with the solid-liquid separation plate 4, and drive them to move from left to right, and perform extrusion and dehydration, and then fall into the temporary storage area on the right side of the partition 20;

[0042] By setting up the extrusion structure, the feces and solid matter are dehydrated during the transportation process, so that the feces and solid matter are compressed into blocks, the water content contained therein is reduced, the wetness is greatly reduced, the fluidity is no longer there, and the cleaning difficulty is reduced.

[0043] like Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the utility model, a cleaning structure is symmetrically arranged on the right side of the partition 20, and the cleaning structure includes a storage frame 11, a guide rod 12, a spring 13 and a scraper block 14.

[0044] In the embodiment of the utility model, when in use, the scraper block 14 is used to scrape off the feces and solid matter remaining in the water filter box 7. At the same time, in order to prevent the scraper block 14 from affecting the rotation of the water filter box 7, the scraper block 14 is arranged on the guide rod 12 with the spring 13, so that when the inclined surface of the scraper block 14 contacts the water filter box 7, it will be forced to move downward, thereby entering the storage frame 11, reducing the obstruction to the rotation of the water filter box 7;

[0045] By providing a cleaning structure, the residue of feces and solid impurities in the water filter box 7 can be reduced.

[0046] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, as a preferred embodiment of the utility model, the extrusion structure includes a transfer unit and an extrusion unit;

The pressure block 10 is installed in a circular array on the surface of the second transmission belt 9 and meshes with the upper end of the water filter box 7.

[0049] In the embodiment of the utility model, when in use, the active roller 5 is started to rotate the first transmission belt 6, thereby driving the water receiving and filtering box 7 to rotate, so as to receive the feces and solid magazines dropped along with the solid-liquid separation plate 4, and drive them to move from left to right. When the water receiving and filtering box 7 moves, the second transmission belt 9 is driven to rotate on the driven roller 8 through the pressing block 10 engaged therewith, and as the degree of engagement with the water receiving and filtering box 7 gradually deepens, the feces and solid magazines stored in the water receiving and filtering box 7 are compressed, and then the sewage contained therein is squeezed out, and then falls into the sewage area on the left side of the partition 20;

[0050] By setting up a transfer unit and an extrusion unit, it is convenient to transport feces and solid matter, and squeeze out the moisture therein, reducing the difficulty of subsequent cleaning.

[0051] like Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment of the utility model, a stirring and breaking structure is also provided in the middle of the processing box 1, and the stirring and breaking structure includes a displacement screw 15 and an isolation placement box 18. The displacement screw 15 is movably installed in the middle of the processing box 1, and a traction block 16 is installed on the surface array of the displacement screw 15. The traction block 16 on the left is set in the sewage area, and the traction block 16 on the right is set in the temporary storage area. A telescopic rod 17 is fixedly installed at the bottom of the traction block 16, and the isolation placement box 18 is fixedly installed at the bottom of the telescopic rod 17. The front and rear sides of the isolation placement box 18 are symmetrically provided with breaking rollers 19.

[0052] In the embodiment of the present utility model, when in use, the displacement screw 15 is started, driving the traction block 16 to move, and indirectly driving the telescopic rod 17 to move, and starting the double-headed motor in the isolation placement box 18, thereby driving the dispersion rollers 19 on both the front and rear sides of the isolation placement box 18 to rotate;

[0053] By arranging the dispersion rollers 19, the sewage in the sewage area can be agitated, the reaction speed can be accelerated, and the feces and solid impurities compressed into blocks in the temporary storage area can be broken and flattened, so as to avoid the accumulation of feces and solid impurities in one place, thereby making the space be reasonably utilized.

[0054] As Figure 5 shown, as a preferred embodiment of the present utility model, the right side surface of the scraping block 14 is arranged as an inclined surface, and when the surface of the scraping block 14 is pressed, it descends along the surface of the guide rod 12.

[0055] In the embodiment of the present utility model, when in use, by arranging the right side surface of the scraping block 14 as an inclined surface, when the surface of the scraping block 14 is oppressed, it will descend along the surface of the guide rod 12.

[0056] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present utility model, a chemical agent adding port 22 is fixedly installed at the top on the left side of the treatment box 1, and a movable plate 21 is arranged on the right side of the treatment box 1.

[0057] In the embodiment of the present utility model, when in use, the sewage in the sewage area can be pumped out or drugs can be added through the chemical agent adding port 22, and the feces and solid impurities in the temporary storage area can be cleaned by opening the movable plate 21.

[0058] As Figure 2 and Figure 4 shown, as a preferred embodiment of the present utility model, both the transfer unit and the extrusion unit are arranged to be inclined downward from left to right, the shape and size of the pressing block 10 are adapted to the shape and size of the storage water filtering box 7, and the meshing degree gradually deepens from left to right.

[0059] In the embodiment of the present utility model, when in use, by arranging both the transfer unit and the extrusion unit to be inclined downward from left to right, and the shape and size of the pressing block 10 are adapted to the shape and size of the storage water filtering box 7, and the meshing degree gradually deepens from left to right, it is convenient for the pressing block 10 to press out the water in the storage water filtering box 7.

[0060] In the above embodiments of the present utility model, a sewage treatment and filtration device based on a farm is provided. When in use, the sewage from the farm enters through the feeding port 2 at the top left of the treatment tank 1, pushes open the movable flap 3, and enters the interior on the left side of the treatment tank 1, coming into contact with the solid-liquid separation plate 4. As a result, the feces and solid impurities in the sewage from the farm are intercepted by the solid-liquid separation plate 4 and move to the front and back sides;

[0061] At the same time, the driving roller 5 is started, causing the first transmission belt 6 to rotate, thereby driving the storage water-filtering box 7 to rotate, so as to receive the feces and solid impurities that fall along with the solid-liquid separation plate 4 and drive them to move from left to right;

[0062] Since the engagement degree of the pressing block 10 with the storage water-filtering box 7 gradually deepens from left to right, when the storage water-filtering box 7 moves, it will drive the second transmission belt 9 to rotate on the driven roller 8 through the engaged pressing block 10;

[0063] At the same time, as the engagement degree of the pressing block 10 with the storage water-filtering box 7 gradually deepens from left to right, the feces and solid impurities received in the storage water-filtering box 7 will be flattened, and then the sewage contained inside will be squeezed out, falling into the sewage area on the left side of the partition plate 20;

[0064] The feces and solid impurities after being compressed and dewatered will fall into the temporary storage area on the right side of the partition plate 20 as the storage water-filtering box 7 moves;

[0065] At the same time, in order to reduce the residue of feces and solid impurities in the storage water-filtering box 7, a cleaning structure is provided. The scraping block 14 of the cleaning structure scrapes off the feces and solid impurities remaining and adhering in the storage water-filtering box 7. At the same time, in order to prevent the scraping block 14 from affecting the rotation of the storage water-filtering box 7, the scraping block 14 is arranged on the guide rod 12 with a spring 13. When the inclined surface of the scraping block 14 contacts the storage water-filtering box 7, it will move downward under force and enter the storage frame 11, reducing the blockage of the rotation of the storage water-filtering box 7;

[0066] At the same time, the displacement screw 15 is started, driving the traction block 16 to move, and indirectly driving the telescopic rod 17 to move. Then, the double-headed motor in the isolation placement box 18 is started, driving the dispersing rollers 19 on the front and back sides of the isolation placement box 18 to rotate, stirring the sewage in the sewage area, improving the speed of its fusion with the medicine added through the medicine adding port 22, and breaking and spreading out the feces and solid impurities compressed into blocks in the temporary storage area, so as to prevent the feces and solid impurities from accumulating in one place, making the space reasonably utilized;

[0067] Subsequently, the sewage in the sewage area can be pumped out through the medicine adding port 22, and the feces and solid impurities in the temporary storage area can be cleaned by opening the movable plate 21.

[0068] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
