Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment, specifically a wastewater treatment device for the production of silicon microbial fertilizer. Background Technology

[0002] Silicon microbial fertilizer is a compound fertilizer that combines silicon with microbial agents. It belongs to the category of bio-silicon fertilizer. Its main components are beneficial bacteria such as Bacillus, which can decompose silicate minerals in the soil, convert insoluble silicon into available silicon dioxide for crop absorption, release silicon through microbial action and improve the soil environment.

[0003] The production of silicon-based microbial fertilizer typically involves fermentation, compounding, granulation, and drying. After each batch of fermentation, the fermentation tank, pipes, and valves need to be thoroughly cleaned and sterilized with hot water and disinfectant to prevent contamination of the next batch of microorganisms. This process generates a large amount of wastewater, which needs to be treated promptly. Existing wastewater treatment devices discharge wastewater into treatment tanks for centralized treatment. However, flocculants need to be added to the treatment tanks each time. Since the fermentation tanks, pipes, and valves need to be cleaned after each batch of fermentation, wastewater is discharged into the treatment tanks in batches. If the sludge in the treatment tanks is not settled in time, the re-entering wastewater will dissolve the coagulated sludge, making it difficult to ensure continuous wastewater treatment.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-9 The diagram shows a wastewater treatment device for silicon microbial fertilizer production, comprising a device shell 1 and four treatment tanks 2 arranged symmetrically inside the device shell 1. A first water injection pipe 3 is fixedly installed on the top of the treatment tank 2, and a second water injection pipe 4 is fixedly installed on the top of the device shell 1. Wastewater is injected into the first water injection pipe 3 through the second water injection pipe 4, and then the wastewater enters the treatment tank 2 through the first water injection pipe 3. A dosing box 5 for injecting inorganic flocculants and organic flocculants is provided on the top of the treatment tank 2. A drain valve 6 is fixedly installed on the bottom of the treatment tank 2, and a drain pipe 7 connected to the drain valve 6 is rotatably installed on the bottom of the device shell 1. The drain valve 6 discharges the flocs formed by sludge into the drain pipe 7, and then discharges them outward from the drain pipe 7. A drain valve 8 is fixedly installed on the outside of the treatment tank 2 for discharging the treated wastewater. The processing mechanism includes two turntables 9 disposed inside the device housing 1. The turntables 9 can adjust the position of four processing tanks 2. The processing mechanism also includes a gear ring 12 fixedly mounted on the surface of the turntables 9. The turntables 9 are rotatably mounted inside the device housing 1. The processing tanks 2 are fixedly mounted between the two turntables 9. A protective shell 13 is fixedly mounted on the outside of the device housing 1. A first motor 14 is fixedly mounted on the bottom of the protective shell 13. A rotating rod 15 extending into the protective shell 13 is fixedly mounted on the output end of the first motor 14. A first gear 16 that meshes with the gear ring 12 is fixedly mounted on the outside of the rotating rod 15, so that the first... Motor 14 drives rotating rod 15 to rotate. Rotating rod 15 drives gear ring 12 to rotate via first gear 16, causing gear ring 12 to drive turntable 9 to rotate. The two turntables 9 can drive the four processing tanks 2 to perform circular motion, realizing the replacement of the positions of the four processing tanks 2. A water injection cylinder 17 is fixedly installed at the bottom of the second water injection pipe 4. A sealing sleeve 18 is fixedly installed between the four first water injection pipes 3. The sealing sleeve 18 is rotatably installed inside the water injection cylinder 17, and a drain hole is opened on the outside of the water injection cylinder 17. When any one of the first water injection pipes 3 is aligned with the drain hole of the water injection cylinder 17, the second water injection pipe 4 can pass through the water injection cylinder. Water is injected into the first water injection pipe 3 through the drain hole on the injection cylinder 17. As the positions of the four treatment tanks 2 are changed, the four first water injection pipes 3 are aligned with the drain holes of the water injection cylinder 17 in sequence, realizing the batch treatment of wastewater. A second sealing ring 34 is fixedly installed between the four drain valves 8. An annular sliding sleeve 35 for limiting the sliding of the second sealing ring 34 is fixedly installed on the inner side of the device housing 1. A drain pipe 36 is fixedly installed on the outer side of the device housing 1, so that when the treatment tank 2 rotates, the second sealing ring 34 can be driven to rotate along the inner side of the annular sliding sleeve 35 through the drain valve 8. When the drain valve 8 is connected to the drain pipe 36, the drain valve 8... The device can drain water from the corresponding treatment tank 2 into the drain pipe 36, so that the drain pipe 36 can discharge the treated wastewater to the outside. The inner side of the device housing 1 has two vertically distributed annular protrusions, and the outer side of the two turntables 9 is provided with annular grooves corresponding to the annular protrusions, so that the annular protrusions provide support for the turntables 9 and ensure the smooth rotation of the turntables 9. The outer side of the water injection cylinder 17 is fixedly installed with two symmetrically distributed collars 37. The top and bottom of the sealing sleeve 18 are in contact with the inner side of the two collars 37, so that the collars 37 provide auxiliary sealing and support for the sealing sleeve 18 and prevent water leakage.

[0022] Example 2: Please refer to Figures 2-9This embodiment further illustrates Example 1. The injection mechanism shown in the figure includes an injection tube 10 disposed at the bottom of the injection box 5. The injection tube 10 is used to inject inorganic flocculant and organic flocculant into the treatment tank 2. The injection mechanism also includes a base plate 19 fixedly installed on the top of the treatment tank 2. The bottom of the injection box 5 is in contact with the top of the base plate 19. The injection box 5 has two storage chambers inside, and injection cylinders 20 are slidably installed on the inner side of the storage chambers. The two injection cylinders 20 and the two storage chambers respectively form two storage spaces. A top plate 21 is fixedly installed between the tops of the two injection cylinders 20. An installation plate 22 is provided at the bottom of the adjusting bracket 11. The top plate 21 is rotatably installed on the bottom of the installation plate 22. A telescopic tube 2 is fixedly installed on the top of the installation plate 22. 3. One end of the adjusting bracket 11 is fixedly connected to the top of the telescopic tube 23. The injection tube 10 is fixedly installed at the bottom of the chassis 19. When any drug storage chamber is aligned with the injection tube 10, the drug in the storage chamber enters the treatment tank 2 through the injection tube 10. Two drug storage boxes 24 are fixedly installed on the top of the device housing 1. The two drug storage boxes 24 are used to store inorganic flocculants and organic flocculants, respectively. When the telescopic tube 23 is aligned with any drug storage box 24, the inorganic flocculant or organic flocculant in the drug storage box 24 enters the telescopic tube 23. A second gear 25 extending to the bottom of the chassis 19 is fixedly installed at the bottom of the injection box 5. Two arc-shaped racks 26 are fixedly installed on the inner side of the device housing 1. The two arc-shaped racks 26 and the two drug storage boxes 24 are connected. The four treatment tanks 2 are arranged in an alternating pattern. When the first storage tank 24 injects inorganic flocculant into the first storage chamber, as the positions of the four treatment tanks 2 change, the treatment tank 2 can drive the chassis 19 and the adjusting bracket 11 to move synchronously, so that the second gear 25 contacts the first arc-shaped rack 26. The arc-shaped rack 26 drives the second gear 25 to rotate half a turn, so that the second gear 25 drives the injection box 5 to rotate half a turn, realizing the position change of the two storage chambers. The storage chamber containing inorganic flocculant is aligned with the injection pipe 10, so that the inorganic flocculant enters the treatment tank 2 through the injection pipe 10. At the same time, the storage tank 24 containing organic flocculant is aligned with the telescopic pipe 23, so that the organic flocculant can enter the storage chamber directly below. When the second gear 25 contacts the next arc-shaped rack 26... The second gear 25 rotates half a turn again, allowing the organic flocculant to be injected into the wastewater through the injection pipe 10, thus achieving sequential injection of inorganic and organic flocculants. A first sealing ring 27 is fixedly installed between the top ends of the four telescopic pipes 23. The first sealing ring 27 is rotatably installed on the top inner wall of the device housing 1, so that when the four telescopic pipes 23 make circular motion, the first sealing ring 27 can seal the telescopic pipes 23 to prevent leakage. A sealing plate 38 is fixedly installed at the bottom of the injection box 5, and the bottom of the sealing plate 38 is in contact with the top of the base plate 19, so that when the injection box 5 rotates, the sealing plate 38 can maintain the seal of the injection pipe 10. Four transparent observation plates 39 are centrally symmetrically distributed on the outer side of the device housing 1.Furthermore, the transparent observation panel 39 and the injection cartridge 20 are on the same horizontal line, facilitating the observation of the injection cartridge 20 by staff.

[0023] Example 3: Please refer to Figures 4-9 This embodiment further illustrates other embodiments. The volume adjustment mechanism shown in the figure includes an adjustment bracket 11 disposed above the injection box 5. The adjustment bracket 11 can adjust the storage amount of the injection box 5. The volume adjustment mechanism also includes a top box 28 fixedly installed inside the adjustment bracket 11. A base plate 29 is fixedly installed at the bottom of the chassis 19. Two symmetrically distributed moving blocks 30 are fixedly installed on the outer side of the mounting plate 22. The top box 28 is fixedly connected to the top of the mounting plate 22. Two screws 31 are rotatably installed between the top box 28 and the base plate 29. The two moving blocks 30 are respectively threaded onto the outer side of the two screws 31. A second motor 32 is fixedly installed on the top of the top box 28. The output end of the second motor 32 is fixedly connected to the adjacent screw 31, and the two... A synchronous belt 33 is rotatably installed between the screws 31, enabling the second motor 32 to drive the corresponding screw 31 to rotate. This screw 31 drives the other screw 31 to rotate synchronously via the synchronous belt 33. When the two screws 31 rotate, they drive the mounting plate 22 to move downwards via the corresponding moving block 30. The mounting plate 22 pushes the top plate 21 downwards, and the top plate 21 drives the injection cylinder 20 to move along the storage cavity of the injection box 5, reducing the storage space between the injection box 5 and the storage cavity. The mounting plate 22 also pulls the telescopic tube 23 to stretch, thereby adjusting the injection amount of inorganic flocculant and organic flocculant. The injection cylinder 20 has a scale strip on its outer side and is made of transparent material, making it easy to observe and judge the storage amount of the injection cylinder 20 and the storage cavity.

[0024] Working principle: First, the worker connects the wastewater discharge pipe to the second water injection pipe 4, allowing the wastewater to enter the water injection cylinder 17 through the second water injection pipe 4. The water injection cylinder 17 then injects the wastewater into the corresponding first water injection pipe 3 through the drain hole, and finally into the corresponding treatment tank 2. Next, the worker loads inorganic flocculant and organic flocculant into two separate storage tanks 24. The storage tank 24 containing inorganic flocculant injects the inorganic flocculant into its corresponding telescopic pipe 23. The inorganic flocculant enters the storage chamber of the injection box 5 directly below the telescopic pipe 23, filling the space between the storage chamber and the injection cylinder 20. Then, the worker starts the first motor 14, which drives the rotating rod 15 to rotate. The rotating rod 15 passes through two... The first gear 16 drives two gear rings 12 to rotate, which in turn drives the turntable 9 to rotate. The turntable 9 drives the four treatment tanks 2 to rotate in a circular motion. The treatment tanks 2 drive the chassis 19 to move synchronously, causing the second gear 25 below the chassis 19 to contact the first arc-shaped rack 26. The arc-shaped rack 26 drives the second gear 25 to rotate, causing the second gear 25 to rotate the injection box 5 half a turn. The injection box 5 drives the two injection cylinders 20 to move synchronously, realizing the position replacement of the two storage chambers. The storage chamber containing inorganic flocculant is aligned with the injection pipe 10, and the inorganic flocculant can enter the corresponding treatment tank 2 through the injection pipe 10. Subsequently, the telescopic pipe 23 above the treatment tank 2 is aligned with the next storage box 24. The organic flocculant in tank 24 enters the storage chamber directly below through telescopic pipe 23. When the second gear 25 on the treatment tank 2 contacts the next arc-shaped rack 26, the arc-shaped rack 26 drives the injection box 5 to rotate half a turn through the second gear 25. The organic flocculant in the storage chamber can then be injected into the treatment tank 2 through the injection pipe 10, realizing the sequential injection of materials into the treatment tank 2. Then, the four treatment tanks 2 drive the four first water injection pipes 3 to move synchronously, causing the four first water injection pipes 3 to drive the sealing sleeve 18 to rotate along the outside of the water injection cylinder 17, realizing the position replacement of the four first water injection pipes 3. The drain hole on the water injection cylinder 17 can then be aligned with the next first water injection pipe 3, facilitating the next injection of wastewater. Wastewater can enter the next treatment tank 2. The wastewater in the first treatment tank 2 can be fully mixed with inorganic flocculants and organic flocculants. Thus, with the intermittent rotation of the first motor 14, the wastewater is stored and treated in batches. Furthermore, the drain valves 8 on the four treatment tanks 2 can drive the second sealing ring 34 to rotate along the inner side of the annular sliding sleeve 35. When the drain valve 8 is aligned with the drain pipe 36 on the outer casing 1 of the device, the drain valve 8 can draw out the treated wastewater and discharge it into the drain pipe 36, which facilitates the discharge of the treated wastewater. The drain valve 6 at the bottom of the treatment tank 2 discharges the separated and settled sludge into the drain pipe 7, thereby realizing the treatment of sludge in the wastewater and achieving the effect of efficient wastewater treatment.
