Description

Technical Field

[0001] This application relates to the field of sludge treatment equipment technology, and in particular to a sludge microbial activation treatment device. Background Technology

[0002] Sludge is a solid and semi-solid substance with varying water content produced during wastewater treatment. Due to the significant differences in properties among various types of sludge, classification is essential, and their treatment and disposal methods differ accordingly.

[0003] Publication No.: CN215102757U, a device for activating sludge microorganisms is proposed. In the process of implementing the device, the sludge is filtered through three different sizes of filter screens. However, since the filter screens are all located inside the equipment, it is too troublesome to disassemble and clean the filter screens one by one when it is necessary to do so later. Therefore, a device for activating sludge microorganisms is proposed to solve the above problems. Utility Model Content

[0004] To address the cumbersome process of disassembling and cleaning filter screens sequentially, this application provides a device for activating sludge microorganisms.

[0005] The sludge microbial activation treatment device provided in this application adopts the following technical solution:

[0006] An activation treatment device for sludge microorganisms includes a fixed frame, a collection box fixedly connected to the bottom of the fixed frame, a treatment box disposed inside the fixed frame, a discharge hopper fixedly connected to the lower end of the treatment box, a fixed frame slidably connected inside the treatment box, a filter screen fixedly connected inside the fixed frame, an outer shell fixedly connected to the surface of the treatment box, a threaded rod rotatably connected inside the outer shell, a fixed shell communicating with the interior of the outer shell fixedly connected to the surface of the treatment box, and a baffle slidably connected inside the fixed shell.

[0007] By adopting the above technical solution, the movement of the filter screen is blocked by the baffle, thereby fixing the filter screen.

[0008] Preferably, the baffle is L-shaped, and the interior of the baffle is threadedly connected to the surface of the threaded rod.

[0009] By adopting the above technical solution, the sliding of the baffle is controlled by setting the threaded rod.

[0010] Preferably, a second motor with its output end extending into the interior of the housing is fixedly connected to the surface of the housing. The output end of the second motor is rotatably connected to the interior of the housing, and the output end of the second motor is fixedly connected to a threaded rod via a coupling.

[0011] By adopting the above technical solution and setting up a second motor, the rotation of the threaded rod is controlled.

[0012] Preferably, a rotating rod is rotatably connected inside the processing box, a stirring rod is fixedly connected to the surface of the rotating rod, and a first motor with its output end extending into the interior of the processing box is fixedly connected to the surface of the processing box. The output end of the first motor is rotatably connected to the interior of the processing box, and the output end of the first motor is fixedly connected to the rotating rod via a coupling.

[0013] By adopting the above technical solution, the first motor is started, and the output end of the first motor drives the rotating rod to rotate, and the rotating rod moves and mixes the sludge.

[0014] Preferably, an elliptical drive plate is fixedly connected to the surface of the rotating rod.

[0015] By adopting the above technical solution, the elliptical shape of the drive plate is used to push the subsequently installed sliding rod.

[0016] Preferably, a fixed rod is fixedly connected inside the processing box, and a sliding rod is slidably connected inside the fixed rod. A tapping plate that contacts the bottom of the filter screen is fixedly connected to the end of the sliding rod away from the drive plate.

[0017] By adopting the above technical solution, the sliding rod makes the striking plate contact the filter screen, causing the filter screen to vibrate and reducing the possibility of the filter screen becoming clogged.

[0018] Preferably, the sliding rod is movably sleeved on the surface inside the fixed rod with a return spring at both ends, which are respectively fixedly connected to the fixed rod and the sliding rod.

[0019] By adopting the above technical solution, the reset sliding of the sliding rod is controlled by setting a reset spring.

[0020] Preferably, a rubber pad that contacts the interior of the processing box is fixedly connected to the side of the fixing frame near the interior of the processing box.

[0021] By adopting the above technical solution, the gap between the fixed frame and the fixed bracket is filled by setting rubber pads, thereby sealing the equipment and reducing the possibility of leakage.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] By activating the second motor, the threaded rod rotates, controlling the movement of the baffle. This releases the filter screen from its fixed position, making it easier for staff to remove and clean it, thus facilitating its use. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0032] This application discloses an apparatus for activating sludge microorganisms.

[0033] Reference Figures 1-5A sludge microbial activation treatment device includes a fixed frame 1. A collection box 6 for collecting treated sludge is fixedly connected to the bottom of the fixed frame 1. A treatment box 2 for installation is installed inside the fixed frame 1. A discharge hopper 5 for discharging treated sludge is fixedly connected to the lower end of the treatment box 2. A fixing frame 3 for installation is slidably connected inside the treatment box 2. A filter screen 12 for filtering sludge is fixedly connected inside the fixing frame 3. A housing 8 for installation is fixedly connected to the surface of the treatment box 2. A threaded rod 17 for driving subsequent installation structures is rotatably connected inside the housing 8. A fixing shell 10 is fixedly connected to the surface of the treatment box 2, and the fixing shell 10 communicates with the interior of the housing 8. The fixed housing 10 has a baffle 11 that blocks the filter screen 12, and the baffle 11 is L-shaped. The inside of the baffle 11 is threadedly connected to the surface of the threaded rod 17. The surface of the outer housing 8 is fixedly connected to a second motor 18 that drives the rotation of the threaded rod 17. The output end of the second motor 18 extends into the inside of the outer housing 8 and is rotatably connected to the inside of the outer housing 8. The output end of the second motor 18 is fixedly connected to the threaded rod 17 through a coupling. When the threaded rod 17 rotates, due to the obstruction of the fixed housing 10, the baffle 11 does not rotate but slides axially under the guidance of the fixed housing 10. The baffle 11 slides inside the fixed housing 10.

[0034] The treatment tank 2 has a rotating rod 7 rotatably connected inside for installation. A stirring rod 13 for turning and mixing sludge is fixedly connected to the surface of the rotating rod 7. A first motor 4 for driving the rotating rod 7 is fixedly connected to the surface of the treatment tank 2. The output end of the first motor 4 extends into the interior of the treatment tank 2 and is rotatably connected to the interior of the treatment tank 2. The output end of the first motor 4 is also fixedly connected to the rotating rod 7 via a coupling. By starting the first motor 4, the output end of the first motor 4 drives the rotating rod 7 to rotate. The rotation of the rotating rod 7 agitates and mixes the sludge, allowing the microorganisms to come into full contact with the sludge. This can effectively treat the harmful substances in the sludge and increase the practicality of the device. This is described in the comparative case and therefore not explained in detail.

[0035] A drive plate 9 for driving the subsequent installation structure is fixedly connected to the surface of the rotating rod 7, and the drive plate 9 is elliptical. A fixing rod 14 for installation is fixedly connected inside the processing box 2. A sliding rod 15 for pushing the subsequent installation structure is slidably connected inside the fixing rod 14. A striking plate 16 for striking the filter screen 12 is fixedly connected to the end of the sliding rod 15 away from the drive plate 9. The striking plate 16 is in contact with the bottom of the filter screen 12.

[0036] A return spring 19, which controls the sliding rod 15, is movably sleeved on the surface inside the fixed rod 14. The two ends of the return spring 19 are fixedly connected to the fixed rod 14 and the sliding rod 15, respectively. The return spring 19 controls the return sliding of the sliding rod 15.

[0037] A sealing rubber gasket is fixedly connected to the side of the fixed frame 3 near the inside of the processing box 2. The rubber gasket is in contact with the inside of the processing box 2. The rubber gasket fills the gap between the fixed frame 3 and the fixed bracket 1, thereby sealing the equipment and reducing the possibility of leakage.

[0038] The processing chamber 2 is equipped with a temperature control system, which includes a sensor module, a control module, and an actuator. The sensor module includes temperature sensors (such as thermocouples and resistance temperature detectors) and humidity sensors to collect environmental parameters inside the processing chamber 2 in real time, so that staff can understand the survival temperature and humidity of microorganisms inside the processing chamber 2. The control module processes the sensor data and compares it with the set value, outputs control signals, and controls the actuator to ensure that the microorganisms are in a suitable survival temperature and humidity. The actuator includes refrigeration and heating equipment, which can regulate the temperature and humidity inside the processing chamber 2 to ensure that the microorganisms have a suitable survival environment. The temperature control system is a conventional and mature technology in this field, so it will not be discussed in detail here.

[0039] The implementation principle of the sludge microbial activation treatment device in this application embodiment is as follows: When the filter screen 12 needs to be disassembled, the operator starts the second motor 18, so that the output end of the second motor 18 drives the threaded rod 17 to rotate, and then the threaded rod 17 drives the baffle 11. Under the guidance of the fixed shell 10, the baffle 11 does not rotate but slides axially, so the baffle 11 moves upward and moves out of the inside of the filter screen 12. Then the device no longer blocks the movement of the filter screen 12. Subsequently, the operator pulls the fixed frame 3, so that the fixed frame 3 drives the filter screen 12 to move out of the inside of the treatment box 2, and then the filter screen 12 can be taken out for cleaning.

[0040] When the filter screen 12 is located inside the processing box 2, and the first motor 4 drives the rotating rod 7 and the stirring rod 13 to rotate to operate the device, the rotating rod 7 simultaneously drives the drive plate 9 to rotate. This causes the sliding rod 15 to move due to the cam profile of the drive plate 9. The movement of the sliding rod 15 causes the return spring 19 to deform, and the movement of the sliding rod 15 pushes the striking plate 16, causing the striking plate 16 to strike the bottom of the filter screen 12. Under the elastic force of the return spring 19, the sliding rod 15 slides accordingly. As the drive plate 9 rotates, the sliding rod 15 moves up and down continuously, and the striking plate 16 repeatedly strikes the bottom of the filter screen 12, causing the filter screen 12 to shake. This shaking of the filter screen 12 reduces the clogging caused by impurities in the sludge, further improving the effectiveness of the device.

[0041] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
