Detailed Implementation
[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0017] like Figures 1-4 As shown, the specific embodiment adopts the following technical solution: it includes a processing cylinder 1; the processing cylinder 1 is a hollow cylindrical structure, and a water inlet pipe 2 and a mud outlet pipe 3 are symmetrically opened through the bottom ring wall of the processing cylinder 1. It also includes: The positioning cylinder 4 is a hollow cylindrical structure and is fixed to the inner bottom surface of the treatment cylinder 1. The positioning cylinder 4 serves a positioning function to facilitate the flow direction of wastewater at the bottom of the treatment cylinder 1. Support rods 15 are symmetrically fixed on the front and rear sides of the annular wall of the positioning cylinder 4, and the cross-section of the support rods 15 is semi-circular to improve the mass of the positioning cylinder 4 and prevent the positioning cylinder 4 from bending and deforming due to the impact of water flow. A guide surface 16 is fixed on the inner bottom surface of the treatment cylinder 1, and the guide surface 16 is inclined from the upper left to the lower right to guide the flow direction of sludge and facilitate the concentration of sludge at the opening of the sludge outlet pipe 3. The motor 5 is fixed to the bottom surface of the treatment cylinder 1. The output end of the motor 5 is equipped with a stirring rod 6. The stirring rod 6 is screwed into the positioning cylinder 4 by bearings. The stirring rod 6 is equipped with a guide rod 7 at equal angles, and the guide rod 7 is located above the positioning cylinder 4. The stirring rod 6 and the guide rod 7 are rotated by the motor 5 to facilitate stirring of the wastewater in the treatment cylinder 1, so that the wastewater and sludge balls can fully contact and react. The filter screen plate 8 is fixed inside the processing cylinder 1 and is located above the positioning cylinder 4, which restricts the position of the sludge balls and separates the sludge balls from the positioning cylinder 4. A vibration ring 17 is fixed on the outer ring wall of the processing cylinder 1 and is connected to the filter screen plate 8 by a support rod. A vibration motor 18 is fixed on the vibration ring 17 and is connected to an external power source to facilitate the transmission of the vibration force of the vibration motor 18 to the filter screen plate 8, thereby causing the filter screen plate 8 to vibrate and preventing sludge residue from remaining on the filter screen plate 8, which would cause the filter screen plate 8 to become clogged. Two drainage pipes 9 are provided, and they are symmetrically screwed onto the annular wall of the positioning cylinder 4 using a rotating rod. The control component 10 is installed inside the positioning cylinder 4 and is connected to the drainage pipes 9. The right drainage pipe 9 is located at the opening of the sludge outlet pipe 3 to drain the wastewater sprayed from the water inlet pipe 2, so that the wastewater quickly fills the bottom space of the treatment cylinder 1. Control component 10 includes: The active bevel gear 11 is fixedly sleeved on the stirring rod 6 and is located inside the positioning cylinder 4. The stirring rod 6 drives the active bevel gear 11 to rotate synchronously. Driven bevel gear 12, there are two driven bevel gears 12, and they are symmetrically screwed on the inner wall of the positioning cylinder 4. The driven bevel gear 12 is fixedly connected to the rotating rod at the end of the corresponding drainage tube 9. The driven bevel gear 12 is meshed with the driving bevel gear 11. The driving bevel gear 11 drives the two driven bevel gears 12 to rotate synchronously, thereby controlling the rotation of the drainage tube 9. The drainage leaf 13 consists of several parts, which are respectively fixed on the annular wall of the left drainage pipe 9. The drainage leaf 13 is set at an angle to increase the contact surface between the drainage pipe 9 and the wastewater and improve the drainage effect of the drainage pipe 9. The sealing layer 14 is disposed on the inner wall of the positioning cylinder 4, and the rotating rod at the end of the stirring rod 6 and the drain pipe 9 is connected to the sealing layer 14 to improve the sealing performance inside the positioning cylinder 4 and prevent wastewater from entering the positioning cylinder 4. The inner wall of the treatment cylinder 1 is provided with a heat insulation layer 19, and the temperature detector 20 is fixed on the ring wall of the treatment cylinder 1. The sensing end of the temperature detector 20 is located inside the treatment cylinder 1, which facilitates the detection and heat preservation of the temperature inside the treatment cylinder 1, so that the anaerobic treatment of wastewater is in a suitable environment.
[0018] When using this invention, wastewater is poured into the treatment cylinder 1 through the inlet pipe 2. Simultaneously, the motor 5 is started, driving the stirring rod 6 and the guide rod 7 to rotate, thereby stirring the wastewater at the bottom of the positioning cylinder 4. This ensures the wastewater is evenly distributed at the bottom of the filter screen plate 8, allowing it to fully contact and react with the sludge balls. The filtration effect of the filter screen plate 8 causes the sludge to settle at the bottom of the treatment cylinder 1. Furthermore, the vibration motor 18 and the vibration ring 17 work together to vibrate the filter screen plate 8, preventing sludge from clogging it. The stirring rod 6 drives the active bevel gear 11 to rotate, which in turn drives the driven bevel gear 12 to rotate synchronously. The driven bevel gear 12 drives the corresponding drainage pipe 9 to rotate, which, together with the drainage blade 13, increases the contact area between the drainage pipe 9 and the wastewater, thereby applying stress to the wastewater from left to right and accelerating the uniform distribution of wastewater. At the same time, the guiding effect of the rotation of the drainage pipe 9 concentrates the settled sludge at the opening of the sludge discharge pipe 3, making it easier to drain the sludge. In addition, the rotation of the right-side drainage pipe 9 prevents the opening of the sludge discharge pipe 3 from being blocked, thus affecting the efficiency of sludge discharge.
[0019] Compared with the prior art, the beneficial effects of this utility model are: The diversion pipe 9 improves the efficiency of uniform distribution of wastewater at the bottom of the treatment cylinder 1. Combined with the stirring rod 6 and the diversion rod 7, the wastewater is stirred, which facilitates full contact between the wastewater and the sludge balls and avoids dead corners. The control component 10 is set up so that the stirring rod 6 and the diversion pipe 9 rotate synchronously through the cooperation of the active bevel gear 11 and the driven bevel gear 12. By using the diversion pipe 9 to guide the flow and the stirring rod 6 to stir, the wastewater is more evenly distributed in the treatment cylinder 1. The vibration ring 17 and the vibration motor 18 are provided to facilitate the transmission of the vibration force generated by the vibration motor 18 to the filter screen plate 8, thereby preventing sludge from clogging the filter screen plate 8. The insulation layer 19 and temperature detector 20 are installed to ensure that the temperature inside the treatment cylinder 1 is within a suitable range, thereby ensuring the efficiency of the anaerobic reaction.
[0020] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
