Description

Technical Field

[0001] The present invention relates to the technical field of sludge dewatering, and more particularly to a river sludge dewatering treatment system. Background Art

[0002] River regulation, also known as "riverbed rectification", is an engineering measure to control and transform rivers. Usually, a large amount of sediment is carried in the river water flow. After precipitation, these sediments accumulate on the riverbed of the river, forming sludge. The sludge will have a very serious impact on the entire river ecosystem. River siltation has increasingly affected the normal functioning of various functions such as flood control, drainage, irrigation, water supply, and navigation. To restore the normal functions of the river, it is necessary to regularly carry out dredging projects on the river. River regulation is crucial for maintaining the river ecosystem and ensuring functions such as flood control, drainage, irrigation, water supply, and navigation. And the treatment of river sludge is a key link among them. Under the long-term action of the river water flow, a large amount of sediment precipitates at the bottom of the river to form sludge. These sludges not only affect the beauty of the river, but also seriously hinder the normal functions of the river, such as reducing the flood discharge capacity of the river and affecting the irrigation water quality.

[0003] In terms of resource utilization, river sludge contains certain potential value. If it can be reasonably treated, it can be transformed into useful resources, such as being used to make building materials, improving soil, etc., realizing turning waste into treasure, reducing the exploitation of natural resources, and conforming to the concept of sustainable development. However, there are many problems in the current process of river sludge dewatering treatment and resource utilization. On the one hand, although the pressing technology can remove water, the filter cake after water removal is usually directly discharged. If the sludge filter cake is directly discharged, a large amount of land may be required for stacking, resulting in a waste of land resources. The untreated and unreused sludge filter cake occupies land, reducing the land use efficiency and affecting the urban spatial planning and development. On the other hand, the problem of water resource waste in the sludge treatment process is prominent. A large amount of wastewater generated during the dewatering process is usually directly discharged without effective treatment. This not only wastes precious water resources, but also may pollute the surrounding water environment, increasing the sewage treatment cost. In addition, there is a lack of effective means to chemically treat the sludge to improve its physicochemical properties, making it difficult for the sludge to fully exert its potential resource value. In view of the above problems, a river sludge dewatering treatment system is proposed to solve them. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a river silt dewatering treatment system, which solves the following problems in current resource utilization. River silt contains certain potential value. If it can be reasonably treated, it can be transformed into useful resources, such as used for making building materials, improving soil, etc., achieving the transformation of waste into treasure, reducing the exploitation of natural resources, and conforming to the concept of sustainable development. However, there are many problems in the process of river silt dewatering treatment and resource utilization. On the one hand, although the pressing technology can remove water, the filter cake after water removal is usually directly discharged. If the silt filter cake is directly discharged, a large amount of land may be required for stacking, resulting in a waste of land resources. The untreated and unreused silt filter cake occupies land, reducing the land use efficiency and affecting the urban spatial planning and development. On the other hand, the problem of water resource waste in the silt treatment process is prominent. A large amount of wastewater generated during the dewatering process is usually directly discharged without effective treatment, which not only wastes precious water resources but also may pollute the surrounding water environment and increase the sewage treatment cost.

The model of the filter press 4 is commercially available, which is prior art and will not be elaborated here;

[0040] The input end of the second slurry pump 11 is connected to the pretreatment component 2 through a pipeline. Below the mounting frame 3 on the upper surface of the base plate 1 is fixedly connected with a first support frame 5. The upper end of the first support frame 5 is fixedly connected with a first lifting conveyor belt 6. In front of the first support frame 5 on the upper surface of the base plate 1 is fixedly connected with a second support frame 7.

The crushing structure composed of the conical hopper 205 and the crushing shaft 206 effectively solves the problem of large impurities in the sludge and improves the efficiency and quality of subsequent treatment.

[0046] Further, several support rods 213 are fixedly connected to the rear side above the bucket lid 227. A medicine cylinder 214 is fixedly connected above the support rods 213. A metering pump 215 for injecting the liquid medicine into the sludge bucket 201 is fixedly installed on the upper surface of the bucket lid 227 below the medicine cylinder 214; a float level controller 212 is fixedly connected to the left side of the metering pump 215 above the bucket lid 227.

The first slurry pump 203 generates suction through the collection pipe 204 to suck the river bottom silt. During this process, the first motor 208 drives the crushing shaft 206 to rotate, crushing the silt entering the conical hopper 205. The crushed silt is screened by the screening plate 207, and large particle impurities are intercepted. The silt meeting the requirements passes through the collection pipe 204, the feed pipe 210, and enters the silt bucket 201 through the connecting pipe 211. After the silt enters the silt bucket 201, the float level controller 212 detects whether the silt reaches the predetermined amount. Then, the metering pump 215 extracts the liquid medicine from the medicine cylinder 214 and injects it into the silt bucket 201 according to the set dosage to chemically treat the silt and improve its physical and chemical properties. At the same time, start the first reducer 216, and its output drives the rotating main shaft 217 to rotate. The rotating main shaft 217 drives the stirring blades 218 to rotate to stir the silt. The driving gear disk 221 rotates together with the rotating main shaft 217, and the driven gear 223 engaged with the driving gear disk 221 drives the rotating rod 222 to rotate. The rotating blades 225 and the arc-shaped stirring rod 224 on the rotating rod 222 further enhance the stirring effect, making the silt and the medicine fully and evenly mixed.
