Description

Technical Field

[0001] This utility model relates to the technical field of sludge sterilization devices, and in particular to a sterilization device for sludge drying. Background Technology

[0002] In the field of sludge treatment and resource utilization, sludge drying equipment is a key piece of equipment for achieving sludge reduction and stabilization, and its sterilization effect directly affects the safety and environmental friendliness of subsequent disposal. Traditional sludge drying and sterilization devices mostly adopt a single sterilization method or a simple fixed structure. Common examples include box-type drying equipment equipped with only a single ultraviolet germicidal lamp, or drum-type drying machines that rely solely on electric heating tubes for high-temperature sterilization. The former typically has an ultraviolet lamp fixedly installed at the top of the chamber, and the sludge passes through from below via a conveyor belt to complete sterilization. The latter, on the other hand, has fixed electric heating tubes inside the drum, and the rotation of the drum brings the sludge into contact with the heating tubes to achieve sterilization and drying.

[0003] However, these traditional sterilization devices use only one method and have a limited range of action. Ultraviolet sterilization alone is limited by the irradiation angle, making it difficult to penetrate the interior of sludge particles and resulting in incomplete sterilization of stacked sludge. High-temperature sterilization, due to the fixed installation of the heating element, only partially contacts the heat source within the drum, leading to uneven drying and sterilization. This is especially problematic for sludge with high moisture content, often resulting in overheating of the outer layer while insufficient sterilization of the interior.

[0004] Secondly, the sterilization components of traditional devices are fixed and cannot be adjusted according to the properties of the sludge. When treating sludge with different moisture content or viscosity, the sterilization efficiency fluctuates greatly. At the same time, the fixed heating tubes or lamps are easily covered by sludge particles after long-term use, affecting the sterilization effect. Moreover, cleaning and maintenance require stopping the machine for disassembly, which is time-consuming and labor-intensive. Utility Model Content

[0005] This invention solves the problems in related technologies and proposes a sterilization device for sludge drying.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A sterilization device for sludge drying includes a base, which comprises a housing and a disc base. The disc base is installed at the center of the upper surface of the housing and is integrally formed with the housing. A toothed ring seat is fitted onto the outer surface of the disc base and is rotatably connected to the disc base. A driving component for rotating the toothed ring seat is also fixedly installed on the housing. A main frame is vertically installed on the upper surface of the disc base. A flow guide shell assembly is fixedly installed in the main frame, and a discharge pipe that mates with the lower end of the flow guide shell assembly is fixedly installed on the housing. A sterilization shell is fitted onto the outside of the main frame, and the lower end of the sterilization shell is fixedly installed on the upper surface of the toothed ring seat.

[0008] As a preferred embodiment, the housing includes a bottom half-shell and a support. The support is installed on the upper end face of the bottom half-shell and is integrally formed with the bottom half-shell. A horizontal seat is fixedly installed on the outer side of the bottom half-shell.

[0009] As a preferred embodiment, the toothed ring seat includes an outer toothed ring and a mating bearing, the mating bearing being sleeved on the outer side of the disc seat, and the outer toothed ring being sleeved and fixed on the outer ring of the mating bearing.

[0010] As a preferred embodiment, the driving component includes a swing motor and a drive gear that meshes with an external gear ring. The swing motor is fixedly mounted on the upper end face of the horizontal seat, and the drive gear is fixedly mounted on the output shaft of the swing motor.

[0011] As a preferred embodiment, the main frame includes a vertical frame and a hanger, the vertical frame being vertically fixed to the upper surface of the base, and the hanger being fixedly installed at the head of the vertical frame.

[0012] As a preferred embodiment, the guide shell assembly includes an inlet shell and a spiral shell, wherein the inlet shell is fixedly installed on the lower end face of the hanger, and the spiral shell is fixedly installed on the lower end of the inlet shell.

[0013] As a preferred embodiment, the sterilization shell includes an insulation tube, a sterilization lamp, and a high-temperature lamp tube, wherein the sterilization lamp and the high-temperature lamp tube are evenly installed on the inner side of the insulation tube and are distributed at intervals.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application achieves all-round, multi-angle sterilization of sludge through the synergistic effect of germicidal lamps and high-temperature lamps, as well as the rotation of the sterilization shell. This effectively kills bacteria, viruses, and pathogens in the sludge, improving its sanitary quality. The high temperature generated by the high-temperature lamps accelerates the evaporation of moisture in the sludge, achieving sludge drying. Simultaneously, the spiral shell design increases the residence time of the sludge within the device, further improving drying efficiency. Furthermore, the use of a swing motor to drive the gear ring seat allows for precise control of the rotation speed and angle of the sterilization shell, making operation simple and convenient. The device's layout is also reasonable, facilitating installation and maintenance. Attached Figure Description

[0027] Reference Figure 1 , Figure 2 and Figure 3 As shown, a sterilization device for sludge drying includes a base 1, which comprises a housing 11 and a disc base 12. The disc base 12 is installed at the center of the upper surface of the housing 11 and is integrally formed with the housing 11. A toothed ring seat 2 is fitted onto the outer surface of the disc base 12 and is rotatably connected to the disc base 12. A driving component 3 for driving the toothed ring seat 2 to rotate is also fixedly installed on the housing 11. A main frame 4 is vertically installed on the upper surface of the disc base 12. A flow guide shell assembly 5 is fixedly installed in the main frame 4, and a discharge pipe 6 that cooperates with the lower end of the flow guide shell assembly 5 is fixedly installed on the housing 11. A sterilization shell 7 is fitted onto the outside of the main frame 4, and the lower end of the sterilization shell 7 is fixedly installed on the upper surface of the toothed ring seat 2. The base 1 serves as the foundation of the entire device, providing support and mounting positions for other components. The toothed ring seat 2 is rotatably connected to the disc seat 12, and is driven to rotate by the driving component 3, so that the sterilization shell 7, which is sleeved on the outside of the main frame 4, can reciprocate within a certain angle, thereby achieving all-round sterilization of the sludge in the guide shell assembly 5. The main frame 4 is used to fix the guide shell assembly 5, ensuring that the sludge can pass smoothly through the guide shell assembly 5 for treatment, and the discharge pipe 6 facilitates the discharge of the treated sludge. This overall structural design enables the various components of the device to work together, improving the efficiency and effect of sludge sterilization treatment. The seat 11 includes a bottom half-shell 111 and a support 112. The support 112 is installed on the upper end face of the bottom half-shell 111, and the support 112 is integrally formed with the bottom half-shell 111. A horizontal seat 113 is fixedly installed on the outer side of the bottom half-shell 111. The seat 11 is further refined into a bottom half-shell 111 and a support 112. The integrally formed design ensures the structural strength and stability of the seat 11. The horizontal seat 113 fixedly installed on the outer side of the bottom half shell 111 provides an installation position for the drive component 3, so that the drive component 3 can stably drive the gear ring seat 2 to rotate, and also facilitates better discharge of the treated sludge.

[0028] Reference Figure 2 and Figure 3 As shown, the gear ring seat 2 includes an external gear ring 21 and a mating bearing 22. The mating bearing 22 is sleeved on the outer surface of the disc seat 12, and the external gear ring 21 is sleeved and fixed on the outer ring of the mating bearing 22. The gear ring seat 2 is composed of an external gear ring 21 and a mating bearing 22. The mating bearing 22 is sleeved on the outer surface of the disc seat 12, and the external gear ring 21 is sleeved and fixed on the outer ring of the mating bearing 22. This structural design allows the gear ring seat 2 to rotate flexibly around the disc seat 12, reducing friction during rotation, improving the smoothness of rotation, and also ensuring the connection stability between the gear ring seat 2 and the disc seat 12.

[0029] Reference Figure 4As shown, the driving component 3 includes a swing motor 31 and a drive gear 32 that meshes with the external gear ring 21. The swing motor 31 is fixedly mounted on the upper end face of the horizontal seat 113, and the drive gear 32 is fixedly mounted on the output shaft of the swing motor 31. The driving component 3 adopts a combination of the swing motor 31 and the drive gear 32. The swing motor 31 is fixed on the horizontal seat 113, and the drive gear 32 is fixed on the output shaft of the swing motor 31 and meshes with the external gear ring 21. By rotating the swing motor 31, the drive gear 32 is driven to rotate, which in turn drives the external gear ring 21 to rotate, thus realizing the rotation of the gear ring seat 2. This driving method has a simple structure, high transmission efficiency, and can accurately control the rotation speed and angle of the gear ring seat 2 to meet different sterilization requirements.

[0030] Reference Figure 3 and Figure 4 As shown, the main frame 4 includes a vertical frame 41 and a hanger 42. The vertical frame 41 is vertically fixed to the upper surface of the tray 12, and the hanger 42 is fixedly installed at the head of the vertical frame 41. The main frame 4 is composed of the vertical frame 41 and the hanger 42. The vertical frame 41 is vertically fixed to the tray 12, providing stable support for the entire main frame 4. The hanger 42 is fixed at the head of the vertical frame 41 and is used to fix the flow guide shell assembly 5, ensuring the accurate installation position of the flow guide shell assembly 5, allowing the sludge to smoothly enter the flow guide shell assembly 5 for treatment, and also improving the overall structural stability of the main frame 4.

[0031] Reference Figure 4 As shown, the flow guide shell assembly 5 includes an inlet shell 51 and a spiral shell 52. The inlet shell 51 is fixedly installed on the lower end face of the hanger 42, and the spiral shell 52 is fixedly installed on the lower end of the inlet shell 51. The inlet shell 51 is fixed to the lower end face of the hanger 42 to facilitate the entry of sludge. The spiral shell 52 is fixed to the lower end of the inlet shell 51. Its spiral structure enables the sludge to form a spiral motion during its descent, increasing the residence time of the sludge in the flow guide shell assembly 5. This allows the sterilization shell 7 to more thoroughly sterilize the sludge, improving the sterilization effect.

[0032] Reference Figure 5 As shown, the sterilization shell 7 includes an insulated tube 71, a sterilizing lamp 72, and a high-temperature lamp 73. The sterilizing lamp 72 and the high-temperature lamp 73 are evenly installed on the inner side of the insulated tube 71, and are spaced apart. The sterilization shell 7 is composed of the insulated tube 71, the sterilizing lamp 72, and the high-temperature lamp 73, which are evenly distributed on the inner side of the insulated tube 71. The insulated tube 71 can reduce heat loss and ensure the efficient execution of the sterilization and drying process. The sterilizing lamp 72 kills bacteria and viruses in the sludge by ultraviolet irradiation, while the high-temperature lamp 73 further sterilizes and dries the sludge by high temperature. The synergistic effect of the two greatly improves the sterilization effect and also achieves the drying treatment of the sludge.

[0033] In this embodiment, during actual operation, the power is turned on, the oscillating motor 31 is started, and the rotation of the gear ring seat 2 and the sterilization shell 7 is checked to ensure smooth rotation. Simultaneously, the sterilization lamp 72 and the high-temperature lamp 73 are turned on, and their working status is checked. Sludge is added to the device through the feed shell 51, and the flow and processing of the sludge within the device are observed. The speed of the oscillating motor 31 and the power of the sterilization lamp 72 and the high-temperature lamp 73 are adjusted according to the actual situation to achieve the best sterilization and drying effect.
