Description

Technical Field

[0001] The invention belongs to the technical field of organic fertilizer production wastewater treatment, and specifically relates to an organic fertilizer production wastewater treatment device and a treatment method thereof. Background Art

[0002] Organic fertilizer is a carbon-containing material that mainly comes from human or animal feces and plant residues, and is applied to the soil to provide plant nutrition as its main function. The nutrients contained in organic fertilizers are mostly in an organic state, which is difficult for crops to use directly. Through the action of microorganisms, a variety of nutrients are slowly released, and nutrients are continuously supplied to crops. Organic fertilizers will produce a large amount of wastewater during the production process, so wastewater treatment equipment is an indispensable equipment for organic fertilizer production.

[0003] The Chinese patent with patent application number CN202221739016.0 discloses a sewage treatment device for organic fertilizer production, including a filter box body and a liquid inlet. A guide plate is arranged at a position corresponding to the liquid inlet inside the filter box body, a rotating shaft is rotatably installed on the inner side of the guide plate, and a plurality of rotating plates are evenly arranged on the rotating shaft; sewage enters the filter box body through the liquid inlet, and when passing through the rotating plate, the impact force causes the plurality of rotating plates to rotate, and the sewage falls on the filter plate below to be filtered, and the debris remains on the filter plate. The rotation of the rotating plate drives the roller to rotate through the driving component, so that the conveying component drives the elastic scraper to rotate and scrapes off the debris on the filter plate. When the elastic scraper rotates to the bottom, it passes through the cleaning plate, and the cleaning plate scrapes off the debris on the elastic scraper and falls into the collecting box, thereby completing the cleaning of the filter plate and effectively preventing the filter plate from being blocked.

[0004] The above-mentioned existing sewage treatment devices for organic fertilizer production can treat sewage generated during the production of organic fertilizers. However, the existing sewage treatment devices of this type filter sewage through a filter plate, and then scrape the debris on the filter plate through a moving elastic scraper. The debris on the filter is not easy to scrape clean, resulting in poor scraping effect. Some debris will still remain on the filter. With long-term use, the filter holes will gradually become seriously clogged, which directly affects the efficiency of sewage filtration.

[0064] The telescopic scraper mechanism 4 includes a vertical plate 41, one side of the vertical plate 41 is provided with a side groove, a lifting scraper 42 is slidably installed in the side groove, the lifting scraper 42 is slidably connected to the vertical plate 41 through a sliding assembly, and the lower end of the lifting scraper 42 contacts the upper end surface of the filter screen 3.

[0065] The sliding assembly includes a plurality of guide posts 11 fixedly mounted on the upper end surface of the lifting scraper 42 . The plurality of guide posts 11 are arranged in parallel and at intervals, and the guide posts 11 are arranged vertically.

[0066] Sliding holes are provided on the upper end surface of the vertical plate 41 at positions corresponding to the guide column 11. The upper end of the guide column 11 passes through the sliding holes on the vertical plate 41 and is located above the guide column 11. The upper end of the guide column 11 is fixedly connected to a limited position circular block 12.

[0067] In this embodiment, the guide column 11 is slidably connected to a sliding hole on the vertical plate 41 , and the sliding hole is used to guide the movement of the guide column 11 .

[0068] In this embodiment, the limiting round block 12 is used to limit the position of the guide column 11 in the sliding hole to prevent the guide column 11 from moving out of the sliding hole on the vertical plate 41, which is convenient for use.

[0069] The driving mechanism includes threaded holes and guide holes opened on the vertical plate 41 and near the front and rear sides thereof, a threaded rod 44 is threadedly connected in the threaded hole, and both ends of the threaded rod 44 are rotatably mounted on the vertical strip plate 43 respectively, and the lower end of the vertical strip plate 43 is fixedly mounted on the mounting box 1.

[0070] A driving motor 45 is fixedly mounted on the vertical bar plate 43 , and a power output end of the driving motor 45 is drivingly connected to the threaded rod 44 . The driving motor 45 is used to drive the threaded rod 44 to rotate.

[0071] A guide cross bar 47 is slidably connected in the guide hole of the vertical plate 41, and both ends of the guide cross bar 47 are fixedly connected to mounting strips 46, and the lower end of the mounting strip 46 is fixedly mounted on the mounting box 1; the guide cross bar 47 is used to guide the movement of the vertical plate 41.

[0072] Guide cavities 24 are provided on the front and rear inner walls of the installation box 1 and above the filter 3 . The guide cavities 24 are arranged parallel to the two sides of the filter 3 . The highest position of the guide cavity 24 passes through the upper end surface of the installation box 1 .

[0073] A reset cavity 23 is provided on the front and rear inner walls of the installation box 1 and at the lowest position close to the filter screen 3. The reset cavity 23 is arranged vertically, and the lower end of the reset cavity 23 is connected to the guide cavity 24, and the upper end of the reset cavity 23 passes through the upper end surface of the installation box 1.

[0074] A reset guide mechanism 48 is provided at a position on the lifting scraper 42 corresponding to the guide cavity 24 , and an end of the reset guide mechanism 48 is slidably installed in the guide cavity 24 to guide the movement of the lifting scraper 42 .

[0075] The reset guide mechanism 48 includes a square groove opened on the lifting scraper 42, in which a square block 481 is slidably connected, and a spring 482 is fixedly connected between the square block 481 and the inner surface of the square groove. The spring 482 outputs elastic force to push the square block 481 to move outward.

[0076] A reset guide rod 483 is fixedly installed on a side wall of the square block 481 away from the spring 482, and one end of the reset guide rod 483 away from the square block 481 passes through the outer surface of the lifting scraper 42, and the outer end of the reset guide rod 483 extends into the corresponding guide cavity 24 and is slidably connected to the guide cavity 24.

[0077] With such a design, when in use, the driving motor 45 is used to drive the threaded rod 44 to rotate. The threaded rod 44 is threadedly connected to the vertical plate 41. The rotation of the threaded rod 44 drives the vertical plate 41 to move. At this time, the guide cross bar 47 is used to guide the movement of the vertical plate 41. The movement of the vertical plate 41 drives the lifting scraper 42 to move on the filter screen 3, which is convenient for use.

[0078] When the lifting scraper 42 moves from the lowest position of the filter screen 3 to the highest position, the lifting scraper 42 makes the lower end surface of the lifting scraper 42 contact with the filter screen 3 under the action of gravity, and the reset guide rod 483 of the reset guide mechanism 48 moves in the guide cavity 24. At this time, the cooperation between the reset guide rod 483 and the guide cavity 24 is used to guide the movement of the lifting scraper 42, so that the lifting scraper 42 moves slowly upward along the inclination angle of the filter screen 3. At the same time, the lifting scraper 42 scrapes off the debris on the filter screen 3 and pushes the debris through the guide shell 7 and the guide frame 8 into the storage box 9.

[0079] When the lifting scraper 42 moves to the position of the guide shell 7, the reset guide rod 483 on the reset guide mechanism 48 moves from the upper end of the guide cavity 24 to the mounting box 1. At this time, the spring 482 outputs elastic force to push the square block 481 to move outward, so that the reset guide rods 483 on both sides of the lifting scraper 42 move outward. At this time, the spacing between the two reset guide rods 483 away from each other at one end is adjusted to the maximum; and the spacing is greater than the width between the inner surfaces on both sides of the mounting box 1, so that the reset guide rod 483 moves to the upper end surface of the mounting box 1, and at this time, the reset guide rod 483 cooperates with the upper end surface of the mounting box 1 to limit the downward movement of the lifting scraper 42.

[0080] When it is necessary to reset the lifting scraper 42, the drive motor 45 is used to drive the threaded rod 44 to rotate counterclockwise to drive the vertical plate 41 and the lifting scraper 42 to move toward the side close to the reset cavity 23. When the reset guide rod 483 of the reset guide mechanism 48 moves to the position of the reset cavity 23, the lifting scraper 42 drives the reset guide rod 483 to move downward along the reset cavity 23 under the action of gravity, so that the lifting scraper 42 is reset.

[0081] In this embodiment, the inner surface of the reset cavity 23 is arranged obliquely, and the depth of the inner surface of the reset cavity 23 gradually decreases from the upper end to the lower end of the reset cavity 23 .

[0082] With such a design, when the lifting scraper 42 drives the reset guide rod 483 to enter the reset cavity 23, the lifting scraper 42 drives the reset guide rod 483 to move downward along the reset cavity 23 under the action of gravity. At this time, the inner surface of the reset cavity 23 squeezes the reset guide rod 483 to compress the spring 482, and the elastic force of the spring 482 can make the reset guide rod 483 move more smoothly in the reset cavity 23 and the guide cavity 24, thereby improving the use effect.

[0083] The cleaning mechanism 5 includes a negative pressure fan 51 fixedly mounted on the mounting box 1 , the feed end of the negative pressure fan 51 is connected to a suction pipe 52 , the other end of the suction pipe 52 is connected to an elastic hose 53 , and the other end of the elastic hose 53 is connected to a suction pipe 55 .

[0084] In this embodiment, a support base 6 is fixedly installed below the negative pressure fan 51, and the support base 6 is fixedly installed on the front side wall of the installation box 1. The negative pressure fan 51 is fixedly installed on the installation box 1 through the support base 6, which is convenient for assembly and installation.

[0085] The suction port 25 is provided at the bottom of the lifting scraper 42 . A communication cavity 26 is provided in the lifting scraper 42 . The lower end of the communication cavity 26 is communicated with the suction port 25 .

[0086] One end of the extraction pipe 55 away from the elastic hose 53 is fixedly mounted on the lifting scraper 42 and communicated with the communication chamber 26 .

[0087] The discharge end of the negative pressure fan 51 is connected to a discharge pipe 54 , and one end of the discharge pipe 54 away from the negative pressure fan 51 is arranged above the storage box 9 .

[0088] With such a design, the negative pressure fan 51 works through the suction pipe 52, the elastic hose 53, the extraction pipe 55 and the connecting cavity 26 to form a negative pressure suction at the suction port 25. At this time, the suction port 25 sucks away the debris remaining on the inclined plate 2 and the filter screen 3, and then discharges it into the storage box 9 through the discharge pipe 54, thereby improving the cleaning effect of the residual debris on the filter screen 3 and improving the use effect, thereby being able to thoroughly clean the debris on the filter screen 3 and prevent the filter screen 3 from being blocked.

[0089] Support columns 19 are fixedly installed on the installation box 1 at positions close to the suction pipe 52 and the discharge pipe 54, and one end of the support column 19 away from the installation box 1 is fixedly connected to a reinforcement sleeve 20, which is fixedly mounted on the corresponding suction pipe 52 and the discharge pipe 54.

[0090] With such a design, the lifting scraper 42 can effectively and automatically scrape and clean the debris intercepted on the filter screen 3 when it moves on the filter screen 3, which not only improves the cleaning efficiency, but also enhances the convenience during use. The cleaned debris is sent to the storage box 9 for temporary storage, which is convenient for use.

[0091] The operation of the negative pressure fan 51 forms a negative pressure suction force at the suction port 25, and the negative pressure suction force can thoroughly suck out and clean the debris remaining on the filter screen 3 after scraping, so that the remaining debris will not cause clogging of the filter screen 3, and the scraping and suction cleaning are carried out simultaneously. The two cleaning methods greatly improve the cleaning quality of the filter screen 3, so that it will not affect the normal filtering operation of the sewage, and enhance the practicability of the device. At the same time, the storage box 9 is also easy to disassemble, which is convenient for subsequent discharge.

[0092] The present invention also provides a method for treating wastewater produced by organic fertilizer production, which is based on the above-mentioned wastewater treatment device for organic fertilizer production, and comprises the following steps:

[0093] Step 1, filtration treatment: The sewage is directed into the installation box 1, and the filter net 3 automatically filters the sewage to intercept debris, and the filtered sewage is retained in the installation box 1.

[0094] Step 2: debris collection: when a lot of debris is accumulated on the filter screen 3, the drive motor 45 and the negative pressure fan 51 are started synchronously. The drive motor 45 drives the threaded rod 44 to rotate clockwise to drive the vertical plate 41 to move from the lowest position of the filter screen 3 to the highest position. At this time, the lifting scraper 42 moves slowly upward along the inclination angle of the filter screen 3 under the action of gravity and the cooperation of the reset guide mechanism 48 and the guide cavity 24. At the same time, the lifting scraper 42 scrapes the debris on the filter screen 3 and pushes the debris through the guide shell 7 and the guide frame 8 into the storage box 9.

[0095] In the step 2, when the vertical plate 41 moves, the guide cross bar 47 is used to guide the movement of the vertical plate 41; the reset guide rod 483 of the reset guide mechanism 48 moves in the guide cavity 24, and at this time, the reset guide rod 483 cooperates with the guide cavity 24 to guide the movement of the lifting scraper 42, so that the lifting scraper 42 slowly moves upward along the inclination angle of the filter screen 3.

[0096] Step 3: Negative pressure suction: The negative pressure fan 51 works through the suction pipe 52, the elastic hose 53, the extraction pipe 55 and the connecting cavity 26 to form a negative pressure suction at the suction port 25. At this time, the suction port 25 sucks away the debris remaining on the inclined plate 2 and the filter screen 3, and then discharges it into the storage box 9 through the discharge pipe 54.

[0097] Step 4: Reset: When the lifting scraper 42 moves to the position of the material guide shell 7, the reset guide mechanism 48 on the lifting scraper 42 moves from the upper end of the guide cavity 24 to the mounting box 1, and the reset guide mechanism 48 cooperates with the upper end surface of the mounting box 1 to limit the lifting scraper 42 to move downward; then the drive motor 45 is started to drive the threaded rod 44 to rotate counterclockwise to drive the vertical plate 41 and the lifting scraper 42 to move toward the side close to the reset cavity 23. When the reset guide mechanism 48 moves to the position of the reset cavity 23, the lifting scraper 42 drives the reset guide mechanism 48 to move downward along the reset cavity 23 under the action of gravity, so that the lifting scraper 42 is reset.

[0098] In step four, the spring 482 in the reset guide mechanism 48 outputs elastic force to push the reset guide rod 483 to move outward. When the reset guide mechanism 48 moves from the upper end of the guide cavity 24 to the installation box 1, the reset guide rod 483 of the reset guide mechanism 48 moves to the upper end surface of the installation box 1. At this time, the reset guide rod 483 cooperates with the upper end surface of the installation box 1 to limit the downward movement of the lifting scraper 42.

[0099] Step 5, deodorization processing: add the deodorant into the installation box 1 through the feeding pipe 13, and then start the driving motor 16 to drive the connecting rod 14 and the stirring rod 15 to rotate, so that the deodorant and the sewage are mixed for deodorization treatment of the sewage.

[0100] In the step 5, the sewage treated in the installation box 1 can also be directed to an external sewage purification device through the discharge pipe 22 for further purification treatment, thereby improving the use effect.

[0101] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
