DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-3As shown, the utility model provides a sludge biochemical leaching device, including a leaching tank 10, a steel grating bridge 11 is arranged on the top of the leaching tank 10, the staff can observe the internal situation of the leaching tank 10 on the steel grating bridge 11, and make better adjustments. A stirring component 20 is arranged at the bottom of the steel grating bridge 11, which can stir the sludge to facilitate more complete decontamination during leaching. A connecting platform 13 is arranged on one side of the leaching tank 10, and a leaching component 30 is arranged on the connecting platform 13.

[0026] In this embodiment, the stirring assembly 20 includes a connecting seat 21, which is arranged at the center of the steel grid bridge frame 11. A driving motor 22 is arranged on the top of the connecting seat 21. A support column 23 is rotatably arranged between the bottom of the connecting seat 21 and the leaching tank 10. The output shaft of the driving motor 22 is hinged to the support column 23. A stirring frame 24 is fixedly arranged on the outer wall of the support column 23. The driving motor 22 drives the support column 23 to rotate, and then the stirring frame 24 stirs the sludge at the bottom, so that the sludge inside the leaching tank forms a flowing state, which is convenient for fully reacting with the biological bacterial liquid.

[0027] Furthermore, a support ring 14 is provided on the inner wall of the leaching tank 10 near the top side, and two support rods 27 are provided between the support ring 14 and the support column 23. The two support rods 27 are movably connected to the support, and the support rods 27 are used to increase the lateral stability of the support column 23 to prevent the support column 23 from radially offsetting and eventually deforming during rotation.

[0028] Among them, the stirring frame 24 includes a first truss 2401, which is fixedly arranged on the outside of the support column 23. Two second trusses 2402 are arranged on both sides of the first truss 2401 near the bottom. Since the bottom of the leaching tank 10 is an inclined surface, the second truss 2402 is inclined to the first truss 2401, so that the second truss 2402 is parallel to the bottom of the leaching tank 10. An arc plate 2403 is arranged on one side of the second truss 2402, and the arc plate 2403 is used to increase the contact area with the sludge so that it can be better stirred.

[0029] In another embodiment, a testing platform 25 is fixedly provided on the outer side of the support column 23 near the top, and the top of the first truss 2401 is fixedly provided on the bottom of the testing platform 25. The function of the testing platform 25 is to facilitate construction personnel to enter the testing platform 25 for observation when a failure occurs in the mixing assembly 20.

[0030] In this embodiment, a protective cover 26 is provided at the bottom of the support rod 27, and the protective cover 26 is coaxial with the detection platform 25. The protective cover 26 can effectively prevent the splashed sludge from entering the top side of the support column 23, thereby preventing the connection between the support column 23 and the drive motor 22 from being corroded by the sludge, resulting in failure to rotate.

[0031] In this embodiment, the leaching component 30 includes a biochemical storage tank 31, which is arranged on the top of the connecting platform 13. An air pump 32 is arranged on the top cover of the biochemical storage tank 31, and an air inlet is arranged on the top cover. The air inlet is connected to the air outlet of the air pump 32 through a pipeline. A leaching pipe 35 is arranged at the bottom of the biochemical storage tank 31, and the leaching pipe 35 passes through the leaching pool 10 and extends to a position close to the stirring component 20. The air pump 32 is used to pressurize the biochemical storage tank 31, so that the biological bacterial liquid inside is squeezed into the spray pipe and sprayed into the leaching pool 10.

[0032] In a preferred embodiment, a honeycomb partition 33 is provided on the inner wall of the biochemical storage tank 31 near the bottom, and a constant temperature heating device 34 is provided at the bottom of the honeycomb partition 33. By setting the temperature of the constant temperature heating device 34, the biological bacterial liquid inside is kept at a temperature suitable for the selected bacterial species, thereby ensuring its activity before spraying.

[0033] In this embodiment, the leaching pipe 35 has an elbow, and a flow meter 36 is provided at the elbow. The flow meter 36 can calculate the usage of the biological bacterial solution, which is convenient for the subsequent determination of the usage of the biological bacterial solution corresponding to the sludge. The other end of the leaching pipe 35 is connected to the outer surface of the protective cover 26, and the bottom array of the leaching pipe 35 close to the inside of the forest filter tank has a plurality of nozzles 3501.

[0034] like Figure 4 As shown, an operating table is arranged on the steel grid bridge 11, and a controller is arranged inside the operating table. The controller is electrically connected to the flow meter 36, the drive motor 22, the air pump 32 and the constant temperature heating device 34. The operation of the stirring assembly 20 is realized by controlling the operating table. The stirring frame 24 stirs the sludge at the bottom of the forest filter tank to increase the fluidity of the sludge so that the biological bacterial liquid reacts fully with it. At the same time, the air pump 32 is controlled to pressurize the biochemical storage tank 31 so that the biological bacterial liquid can be sprayed from the leaching pipe 35 into the forest filter tank. The constant temperature heating device 34 is used to heat the biological bacterial liquid inside the biochemical storage tank 31 to ensure that it is kept at a suitable temperature for the survival of the biological bacteria and to ensure that it remains active before use. The flow meter 36 can collect the usage of the biological bacterial liquid, which is convenient for the subsequent statistics of the usage of the biological bacterial liquid during the sludge treatment of the corresponding batch.

[0035] The above structure solves the problem that in the existing biochemical forest filter, the density and high solid content of the sludge make it difficult for the biological bacteria to spread evenly in the sludge, thereby limiting the effective contact and reaction between the biological bacteria and the pollutants in the sludge, resulting in low efficiency of the biochemical leaching process and failure to achieve the expected decontamination effect.

[0036] It should be noted that the specific models and specifications of the controller, flow meter 36, drive motor 22, air pump 32 and constant temperature heating device 34 need to be selected and determined based on the actual specifications of the device, etc. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and principles of the controller, flow meter 36, drive motor 22, air pump 32 and constant temperature heating device 34 are clear to those skilled in the art and will not be described in detail herein.

[0038] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
