Description

Technical Field

[0001] This application relates to the field of sludge treatment equipment technology, and in particular to a protective and precise deodorization mechanism for a sludge plate and frame desludge dewatering machine. Background Technology

[0002] In municipal sewage treatment and industrial wastewater treatment, sludge dewatering is a crucial step. Plate and frame dewatering machines are widely used in sludge dewatering operations due to their high dewatering efficiency and low sludge moisture content. However, during operation, the decomposition of organic matter in the sludge produces large amounts of malodorous gases containing hydrogen sulfide, ammonia, and volatile organic compounds. If these gases are directly released into the surrounding environment, they will not only seriously affect the health of on-site operators but also cause air pollution, failing to meet environmental emission requirements and occupational health and safety standards.

[0003] Existing plate and frame desliming machines typically lack targeted protective and deodorizing structures. Some simple protective devices can only provide partial shielding and cannot create a closed protective space, resulting in poor deodorization. Furthermore, most existing devices do not consider the convenience of operators, lacking dedicated operating platforms, leading to low safety and low work efficiency during equipment maintenance and parameter adjustments. Therefore, there is an urgent need for a protective and deodorizing mechanism that can effectively block the diffusion of malodorous gases, achieve precise deodorization, and provide a safe working space for operators, thus addressing the environmental and safety pain points in the application of existing plate and frame desliming machines. Utility Model Content

[0004] To address the aforementioned problems, this application provides a protective and precise deodorization mechanism for sludge plate and frame desludge dewatering machines.

[0005] The protective precision deodorization mechanism for a sludge plate and frame desludge dewatering machine provided in this application adopts the following technical solution: A protective and precise deodorization mechanism for a sludge plate and frame dewatering machine is provided, disposed outside the plate and frame dewatering machine. The mechanism includes: a protective deodorization system covering the outside of the plate and frame dewatering machine to prevent odors generated during operation from directly dissipating into the external environment; the protective deodorization system includes: a protective baffle corresponding to the long diameter end of the plate and frame dewatering machine, a side panel connecting two protective baffles, and a circulating deodorization structure for extracting odorous gases. The protective baffles and the side panel cooperate to form a protective area covering the plate and frame dewatering machine; and an operating protective platform erected outside the plate and frame dewatering machine to provide an operating area for personnel.

[0006] Furthermore, the protective baffle includes: a vertically arranged baffle body, an angle-adjustable plate connected to the top of the baffle body, the angle-adjustable plate being angle-adjustable; an air intake fan installed on the angle-adjustable plate, through which air is introduced into the protected area; and a pipe positioning frame fixed to the inner side of the baffle body, the pipe positioning frame defining the position of the circulating deodorization mechanism, and by adjusting the angle of the angle-adjustable plate so that the angle-adjustable plate covers the top area of ​​the plate and frame sludge dewatering machine.

[0007] Furthermore, the operating protective platform includes: a load-bearing connecting seat fixedly engaged with the side panel; a longitudinal support fixed above the load-bearing connecting seat; a working platform mounted above the longitudinal support and extending a predetermined distance horizontally along the plate and frame desliming machine; the top surface height of the working platform being adapted to the operating surface of the plate and frame desliming machine; and a guardrail surrounding the outside of the working platform.

[0008] Furthermore, the circulating deodorization structure includes: forming an annular passage; an air exchange pump that provides suction power to the air intake duct assembly; and a plurality of deodorization suction heads disposed on the air intake duct assembly and arranged at equal intervals along the annular passage.

[0009] Furthermore, the air intake duct assembly includes: an air exchange duct and an air exchange main pipe respectively fixed to two protective baffles, and a matching connecting pipe connected to both ends of the air exchange duct and the air exchange main pipe. The air exchange duct, the air exchange main pipe and the matching connecting pipe form an annular air intake passage, and the air intake pump is fixed at the center position of the air exchange main pipe.

[0010] Furthermore, the deodorizing suction heads are symmetrically distributed along the horizontal centerline of the ventilation duct, the main ventilation pipe, and the connecting pipe, and the openings of the deodorizing suction heads face the interior of the protected area. The output end of the ventilation pump is connected to a guide pipe.

[0011] Furthermore, the other end of the guide pipe is connected to a deodorization delivery pipe, which in turn is connected to a purification device.

[0012] In summary, this application includes the following beneficial technical effects: By blocking the spread of malodorous gases through a closed protective area, and combining it with a ring-shaped air intake passage and symmetrically distributed deodorizing nozzles, the malodorous gases can be accurately and comprehensively extracted. Combined with external purification equipment, the gases can be discharged in compliance with standards, effectively solving the malodorous pollution problem of plate and frame sludge dewatering machines.

[0013] The design of the dedicated operating protective platform adapts the height of the work platform to the operating surface of the equipment. Combined with protective railings, it provides a safe working space for operators, improving the convenience and safety of operation. Attached Figure Description

[0020] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0021] This application discloses a protective and precise deodorization mechanism for a sludge plate and frame desludge dewatering machine, which is installed outside the plate and frame desludge dewatering machine 1 and includes a protective deodorization mechanism 2 and an operating protective platform 5. The protective deodorization mechanism 2 is installed outside the plate and frame desludge dewatering machine 1 to prevent the odor generated by the plate and frame desludge dewatering machine 1 from being directly emitted into the external environment. The operating protective platform 5 is installed outside the plate and frame desludge dewatering machine 1 to provide a safe operating area for the operator.

[0022] like Figures 1 to 2 As shown, the protective deodorization mechanism 2 includes a protective baffle 3, a side combination plate 4, and a circulating deodorization structure. The protective baffle 3 is set at the long diameter end of the plate and frame desliming machine 1. The side combination plate 4 is connected between the two protective baffles 3. The protective baffle and the side combination plate 4 work together to form a closed protective area covering the plate and frame desliming machine 1, ensuring that malodorous gases only accumulate within the protective area and preventing them from spreading outward.

[0023] In the above embodiments, further, as Figures 2 to 4As shown, the protective baffle 3 serves as a shield and functional load-bearing component for the long-diameter end of the protected area. It includes a baffle body 31, an adjustable angle plate 32, an air intake fan 33, and a pipe positioning frame 34. The baffle body 31 is vertically arranged, and its height is adapted to the height of the plate and frame desliming machine 1, effectively shielding the side area of ​​the long-diameter end of the plate and frame desliming machine 1 to form a protective base. The adjustable angle plate 32 is connected to the top of the baffle body 31. The two are adjusted by hinges, adjusting bolts, hydraulic rods, and gears to achieve angle adjustment. The operator can adjust the tilt angle of the adjustable angle plate 32 according to the top size of the plate and frame desliming machine 1 and the operation requirements, so that the adjustable angle plate 32 covers the top area of ​​the plate and frame desliming machine 1. The protective space is further sealed to prevent malodorous gases from escaping from the top. The air intake fan 33 is installed on the angle-adjustable plate 32, with its air outlet facing the inside of the protected area. When working, it can introduce fresh air into the protected area, forming an air circulation to prevent oxygen deficiency in the protected area from affecting equipment operation. On the other hand, it can push the malodorous gases in the protected area to flow towards the suction end of the circulating deodorization structure, improving deodorization efficiency. The pipe positioning frame 34 is fixed inside the baffle body 31. Its structure can adopt U-shaped clamps, grooves, etc., to limit and fix the position of the pipe components of the circulating deodorization structure, ensuring that the connection between the circulating deodorization structure and the protective baffle 3 is stable and preventing pipe shaking from affecting the suction effect.

[0024] The side panel 4 is made of metal sheet or high-strength plastic sheet, and its length is adapted to the short diameter of the plate and frame desliming machine 1. The side panel 4 is higher than the height of the baffle body 31, which improves the protection performance. The two ends of the side panel 4 are detachably connected to the sides of the two protective baffles 3 by bolts, buckles or other means, and together with the protective baffles 3, they form a closed protective area. At the same time, observation windows (transparent acrylic windows) can be opened on the surface of the side panel 4, so that the operators can observe the working status of the plate and frame desliming machine 1 and understand the operation of the equipment without disassembling the device.

[0025] The circulating deodorization structure is used for precise extraction and removal of malodorous gases within the protected area. It includes an air intake duct assembly, an air exchange pump 64, and a deodorization suction head 65. The air intake duct assembly serves as the transport channel for malodorous gases and includes an air exchange duct 61, an air exchange main pipe 63, and a connecting pipe 62. The air exchange duct 61 and the air exchange main pipe 63 are fixed to the inner sides of two protective baffles 3 via pipe positioning brackets 34. Both are arranged along the long axis of the plate and frame sludge dewatering machine 1, and their lengths are adapted to the lengths of the protective baffles 3. Two connecting pipes 62 are provided, connecting the two ends of the air exchange duct 61 and the two ends of the air exchange main pipe 63, respectively. This allows the air exchange duct 61, the air exchange main pipe 63, and the connecting pipe 62 to form a ring-shaped air intake passage surrounding the protected area, ensuring effective coverage of malodorous gases at all locations within the protected area. The ventilation pump 64 is fixed at the center of the ventilation main pipe 63, and its air inlet is connected to the ventilation main pipe 63. When working, it can generate negative pressure suction to provide continuous suction power for the suction pipe assembly, driving the malodorous gas in the protected area into the suction pipe assembly. The housing of the ventilation pump 64 is fixed to the outer wall of the ventilation main pipe 63 by a bracket to ensure stable installation and avoid violent vibration during operation. The deodorizing suction head 65 adopts a trumpet-shaped structure (the large diameter end is the suction end and the small diameter end is the connection end). Several of them are set at equal intervals along the annular passage of the suction pipe assembly. The deodorizing suction heads 65 are symmetrically distributed along the horizontal center line of the ventilation pipe 61, the ventilation main pipe 63 and the matching connecting pipe 62, with the suction end facing the inside of the protected area. The trumpet-shaped structure design can expand the suction area, and the symmetrical distribution layout can ensure uniform negative pressure in all positions in the protected area, realize accurate and comprehensive suction of malodorous gas, and avoid local gas stagnation.

[0026] In addition, the output end of the ventilation pump 64 is connected to a guide pipe 66, and the other end of the guide pipe 66 is connected to a deodorization delivery pipe 67. The end of the deodorization delivery pipe 67 away from the guide pipe 66 is connected to an external purification device 7 (activated carbon adsorption tower, biological filter, etc.). After the malodorous gas enters the suction pipe assembly through the deodorization suction head 65, it enters the external purification device 7 in sequence through the ventilation main pipe 63, the guide pipe 66, and the deodorization delivery pipe 67 under the drive of the ventilation pump 64. After purification treatment to meet the standards, it is discharged into the atmosphere, realizing the harmless treatment of malodorous gas and meeting environmental protection requirements.

[0027] The operating protective platform 5 is used to provide operators with a safe and convenient working platform, making it convenient for personnel to perform operations such as parameter adjustment, filter cloth replacement, and equipment maintenance of the plate and frame desliming machine 1. The operating protective platform 5 includes a load-bearing connecting seat 51, a longitudinal support 52, a working platform 53, and a guardrail 54. The load-bearing connecting seat 51 is fixed to the outer wall of the side combination plate 4 by bolts, or directly connected to the base of the plate and frame desliming machine 1, providing a stable support foundation for the operating protective platform 5 and ensuring that the overall structure meets the load-bearing capacity standards; the longitudinal support 52 has multiple (preferably 4, corresponding to the four corners of the load-bearing connecting seat 51), the bottom end of which is welded or bolted to the load-bearing connecting seat 51, and the top end is connected to the bottom of the working platform 53, playing a vertical support role; the height of the longitudinal support 52 can be designed according to the operating surface height of the plate and frame desliming machine 1, ensuring that the top surface height of the working platform 53 is aligned with the plate and frame. The operating surface of the desliming machine 1 is adapted (flush with or slightly lower than the operating surface by 5-10cm) to facilitate the operator's reach to operate the equipment; the working platform 53 is made of non-slip metal plate and is mounted on the longitudinal support 52, extending a predetermined distance (e.g., 50-80cm) along the horizontal direction of the plate and frame desliming machine 1 to provide sufficient operating space; the surface of the working platform 53 can be provided with non-slip texture or covered with non-slip mats to prevent personnel from slipping when working in wet environments; the guardrail 54 is installed around the outer edge of the working platform 53, which can effectively prevent the operator from falling from the edge of the working platform 53.

[0028] In actual use, firstly, the protective baffle 3 of the protective deodorization mechanism 2 is installed at the long diameter end of the plate and frame sludge dewatering machine 1. The two protective baffles 3 are connected by the side combination plate 4 to form a closed protective area. Adjust the angle of the adjustable plate 32 so that it covers the top of the plate and frame sludge dewatering machine 1 to complete the sealing of the protective space. Start the air exchange pump 64 and the air intake fan 33 of the plate and frame sludge dewatering machine 1 and this mechanism. The air intake fan 33 introduces fresh air into the protected area to form an air circulation. The air exchange pump 64 generates negative pressure, driving the malodorous gas in the protected area to enter the suction pipe assembly through the deodorization suction head 65. It then passes through the air exchange pipe 61, the connecting pipe 62, the main air exchange pipe 63, and then through the guide pipe 66 and the deodorization delivery pipe 67 to enter the external purification equipment 7. After purification, it is discharged. Operators can enter the operating protective platform 5 through the edge of the working platform 53 to operate and maintain the plate and frame desliming machine 1 on the working platform 53. The guardrail 54 ensures personnel safety. At the same time, the operating status of the equipment can be observed in real time through the observation window on the side combination plate 4. Daily monitoring can be completed without disassembling the protective structure.
