Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and particularly to a sludge dewatering treatment device. Background Art

[0002] A large amount of sludge is generated during the sewage treatment process. If the sludge that has not been effectively treated directly enters the environment, it will cause secondary pollution, polluting water bodies, soil and the atmosphere. The initial moisture content of the sludge is about 75% to 85%. It is necessary to concentrate and dehydrate the sludge. After effectively reducing the moisture content of the sludge, subsequent treatments such as landfill, composting and incineration can be carried out. Sludge dewatering refers to a sludge treatment method that removes water from the flowing raw, concentrated or digested sludge and converts it into a semi-solid or solid sludge cake. After dehydration, the moisture content of the sludge can be reduced to 55% to 80%, depending on the nature of the sludge and sediment and the efficiency of the dewatering equipment. The existing sludge dewatering methods are mainly natural drying method and mechanical dewatering method. Among them, the natural drying method requires a large amount of land resources and a long time period. The mechanical dewatering method includes filtration method and centrifugation method. The equipment used in the filtration method includes plate and frame filter press and belt filter press. The plate and frame filter press squeezes the sludge through the plate and frame, so that the water in the sludge is discharged through the filter cloth to achieve the purpose of dehydration. The belt filter press is composed of two upper and lower tensioned filter belts that sandwich the sludge layer and pass through a series of regularly arranged roller presses in an S shape. Relying on the tension of the filter belt itself, the squeezing and shearing forces on the sludge layer are formed, and it runs continuously to squeeze out the water in the sludge layer, thereby realizing sludge dewatering.

[0016] Compared with the technical solutions published in the existing technical materials, the components of the utility model have good coordination, excellent treatment effect, high production efficiency, good long-term operation stability of the equipment, and long service life. It relies on the tension of the filter belt itself to form a squeezing and shearing force on the sludge layer, squeezes out the capillary water in the sludge layer, and realizes sludge dehydration. It has the advantages of large treatment capacity, relatively simple repair and maintenance, low energy consumption, ability to achieve continuous operation, high dehydration efficiency, long service life, and no need for repeated adjustment during commissioning and operation according to different materials. The dependence on the conditioning of the agent is also greatly reduced. Even if the dosage is insufficient and the conditioning effect is not good, the capillary water in the sludge can still be effectively converted into free water and removed in the gravity dehydration zone 17. The sludge fluidity entering the multi-roller pressing zone 19 from the wedge-shaped pre-pressing zone 18 is greatly reduced, and effective squeezing can be achieved in the multi-roller pressing zone 19, thereby reducing the amount of agent used, effectively reducing the treatment cost, and reducing the sludge viscosity and the clogging of the filter belt. The utility model has three filter belts: a concentration filter belt 3, an upper dehydration filter belt 4 and a lower dehydration filter belt 5. There is also an extended gravity dehydration zone 17 before the multi-roller pressing zone 19 of the ordinary belt filter, which not only improves the dehydration efficiency and reduces the chemical agents, but also greatly reduces the energy consumption. By setting the gravity dehydration zone 17, the pre-pressing zone 18 and the multi-roller pressing zone 19, it is possible to ensure a better dehydration and concentration effect; the tension of each filter belt is controlled by the concentration roller adjusting cylinder 26, the upper roller adjusting cylinder 29 and the lower roller adjusting cylinder 34 to ensure that the tension of the concentration filter belt 3, the upper dehydration filter belt 4 and the lower dehydration filter belt 5 is constant, and the tension will not fluctuate due to changes in the feed amount, thereby ensuring a balanced and stable operation effect and ensuring that each filter The belt has appropriate slackness to provide sufficient contact area and pressure, and can also ensure that the sludge is evenly distributed on the filter belt to avoid accumulation or thinning, further improving the dehydration efficiency and effectively reducing energy consumption; in production operation, due to the many factors that affect the uniform force on the filter belt, the filter belt is prone to deviation and folding. Once the filter belt has creases, the creases frequently rub against the sludge scraper, which is prone to excessive wear and tear, resulting in a significant shortening of the filter belt life and causing greater economic losses. By arranging a concentration correction device 20, an upper belt correction device 21, and a lower belt correction device 22, it is possible to ensure that the above-mentioned filter belts are correctly aligned and the filter belts are corrected in a timely and effective manner to ensure that the equipment can carry out production operations continuously and stably.

[0018] According to the instruction manual Figure 1As shown, the difference between this embodiment and embodiment 1 is that a cleaning water inlet 35 is provided at the lower right portion of the frame 1, a concentrated cleaning nozzle 36 is provided in the gravity dehydration area 17, a filter belt upper cleaning device 37 is provided at the upper portion of the frame 1 to the left of the dehydration motor 10, and a filter belt lower cleaning device 38 is provided at the lower portion of the frame 1 below the small dehydration roller 16.

[0021] Example 4:

[0022] According to the instruction manual Figure 1 As shown, the difference between this embodiment and embodiments 1-3 is that a control box 42 is provided on the frame 1 below the sludge reaction tank 2.

By automatically controlling the feed speed and concentration, they are adapted to the processing capacity of each filter belt, avoiding overloading and clogging, making it safer, more convenient, and more reliable to use.

[0023] Example 5:

[0024] According to the instruction manual Figure 1As shown, the difference between this embodiment and Embodiments 1-4 is that the driving roller 11, the driven roller 12, the main dewatering roller 15, and the small dewatering roller 16 are rollers with drain holes evenly distributed on their outer circumferential surfaces; and / or, an alarm 43 is provided at the top of the frame 1 to the right of the concentration driving roller 8. The setting of the alarm 43 can give an alarm in time when the device fails, improving safe production. The whole device runs smoothly and is more reliable in use, meeting the actual use requirements. The design of each roller with drain holes can effectively improve the sludge dewatering treatment capacity, enabling the sludge to be dewatered simultaneously on both sides. The two sides of the concentration filter belt 3, the upper dewatering filter belt 4, and the lower dewatering filter belt 5 are quickly dewatered during the pressure filtration process, shortening the dewatering time. The smaller small dewatering rollers 16 at the rear are arranged in an S shape, and the setting of the contact angles of the upper dewatering filter belt 4 and the lower dewatering filter belt 5 can ensure a better combined effect of pressure and shear force, greatly improving the dewatering efficiency of the mud cake.
