Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sludge treatment equipment, in particular to a sludge treatment device. BACKGROUND

[0002] With the rapid development of urbanization and industrialization, the sludge production of municipal, printing and dyeing, oil refining and petrochemical, food and other industries is also increasing year by year. It is estimated that the annual output of sludge in China will exceed 100 million tons in 2025. In addition to a large amount of water in the sludge, it also contains a large amount of heavy metals, organic matter, nitrogen and phosphorus, and other plant nutrients, as well as pathogenic microorganisms and parasitic eggs. If the sludge is not properly treated, it will have adverse effects on the environment and human health, and needs to be stabilized, reduced and harmlessly treated. With the increasing understanding of the environmental risks and hazards of sludge in recent years, society has paid more and more attention to the disposal of sludge.

[0003] In the related art, the sludge treatment mainly has the following treatment methods: mechanical dewatering can separate the free state water in the sludge, and the moisture content of the treated sludge can be less than 50%. However, due to the lack of stability and sterilization, the organic matter content is not reduced, so mechanical dewatering is not enough to meet the requirements of subsequent treatment and disposal. Anaerobic digestion technology can kill part of the pathogenic bacteria and parasitic eggs, and is not easy to rot and stink, and can produce biogas to realize the effective recovery of sludge biomass energy. However, it consumes a large amount of heat energy, the process residence time is long, the initial debugging time is long, and the moisture content of the sludge after anaerobic digestion is still high, so subsequent treatment is necessary. The aerobic fermentation technology can kill pathogenic bacteria and weed seeds in the sludge; the operation cost is relatively low, but the occupied area is large, and a large amount of odor is generated during composting, polluting the surrounding environment. The lime stabilization technology has small investment, low operation cost, small occupied area and simple operation and management, but due to the large amount of added lime, the degree of reduction is relatively low, and the cost of reagent use is high.

The first slide rod 5 and the second slide rod 6 cooperate with the first through hole and the second through hole of the treatment box 1 respectively. With the sliding of the slide rods, the compression roller 3 rolls in the treatment box 1 to roll the sludge.

[0034] The motor 10 drives the reciprocating lead screw 8 to rotate, which can realize precise control of the movement of the connecting rod 7, so as to accurately adjust the rolling speed and direction of the compression roller 3.

The engagement of the driving gear 11 and the driven gear 12 and the cooperation of the lead screw nut 9 and the reciprocating lead screw 8 form an efficient transmission system, which can efficiently convert the rotary motion of the motor 10 into the reciprocating rolling motion of the compression roller 3. Through the design of the rotating speed of the motor 10 and the reciprocating lead screw 8, the rolling speed and frequency of the sludge can be accurately controlled, so as to realize fine adjustment of the drying rate and effect of the sludge.

The end of the first telescopic part 1302 is connected with the rake 4, and when the first telescopic part 1302 telescopes, the rake 4 also moves, thereby realizing the loosening and mixing of the sludge and helping to improve the sludge drying effect.

[0039] The sludge treatment device 100 of the embodiment can flexibly adjust the position and movement speed of the rake 4 through the telescoping of the first telescopic rod 13 to adapt to different sludge treatment needs. The combination of the movement of the rake 4 and the rolling of the sludge can enhance the mixing and moisture distribution inside the sludge, improving the drying efficiency.

[0042] Specifically, after the dried sludge needs to be discharged, the rotary motor 14 drives the mounting plate 401 to rotate, and the mounting plate 401 is rotated to below the rake claw 402. The mounting plate 401 is used to scrape the sludge to the sludge outlet 102, which realizes effective collection and discharge of the sludge, and ensures timely cleaning of the sludge in the treatment tank 1.
