Description
Technical Field
The utility model discloses be applied to the shredding field of silt, specifically be a cubic silt reducing mechanism with stoving function.
Background
With the continuous development of economy in China, the utilization rate of river channels is gradually increased, which brings about the climax of water conservancy and port channel engineering construction, and in some river channels with sludge distributed at the bottoms, a large amount of waste sludge is inevitably generated in channel dredging and widening and port new construction and extension projects. However, the silting phenomenon is more serious because the middle and small river channels are not as easily valued as the large river channels.
In the past sludge treatment process, the river channel has the phenomenon of 'dredging' in winter. And (3) composting the dug river mud, and carrying out farming by using the compost as a fertilizer, thereby realizing the reutilization of the mud. However, at present, the industry is rapidly developed, industrial sewage is discharged into rivers in large quantity, river bottom sludge is polluted, and harmful sludge accumulated in the river channels is increased gradually. In order to solve the problem, the country adopts dredging engineering measures to strengthen the treatment strength of the medium and small river channels, which is not only beneficial to the normal use of the river channels, but also contributes to the overall development of the river channels. The dredging and sludge treatment technology of the river channel is an important component in river channel treatment, however, the efficient treatment of the waste sludge from the river channel cleaning is always a problem, most sludge reduces the water content thereof by natural air drying for use, but the sludge has extremely long dehydration time and seriously occupies land resources; massive sludge is difficult to be recycled, the amount of the sludge which is recycled is far less than thousands of sludge generated in riverways every year, and the subsequent treatment and disposal technology of the sludge is in urgent need of development.
At present, most of sludge fished from river channels cannot be used as fertilizer in the soil like the eutrophic sludge in the early stage, so that a great part of sludge fished from river channels and untreated is discarded, and only a small part of sludge is used for farmlands, building materials and the like. Under the normal condition, the sludge salvaged from the river channel by professional equipment is not well utilized, but is stacked in the land for natural air drying, so that the cost of occupying the land by stacking the sludge is increased, and more seriously, harmful substances such as heavy metal in the sludge can cause secondary pollution to the environment. The naturally air-dried sludge placed in the soil has high viscosity, is difficult to develop into small blocks which are convenient for subsequent utilization in the dehydration process, and the conventional sludge crushing device is limited, so that the invention solves the problem that the large-block sludge is crushed into small blocks.
The existing sludge dewatering methods mainly comprise four methods: firstly, a natural dehydration method: the water in the sludge is naturally lost through solar heat energy, wind energy and the gravitational potential energy of water, and the defects that the sludge is greatly influenced by weather, the efficiency is lower under natural dehydration and the period is long; II, vacuum dehydration: an impermeable film, a vacuum pipeline and the like are laid in a pre-built treatment tank, film covering and vacuum pumping are carried out on sludge, and the sludge is dewatered by utilizing vacuum pressure; thirdly, a geotextile bag dehydration method: the permeability and the pressure of the soil engineering bag are utilized to discharge the water in the sludge, the application range is narrow, and when the sludge with high organic matter content is treated, the soil engineering bag is easy to block; fourthly, mechanical dehydration: the centrifugal dehydrator is mainly divided into a centrifugal dehydrator, a plate-and-frame filter press and a belt filter press, in the rotating process of the centrifugal dehydrator, the rotating wheel or the outer edge of the spiral is easy to wear and tear, the rotating wheel or the outer edge of the spiral is required to be frequently replaced, the cost is high, and the energy consumption of the plate-and-frame filter press and the energy consumption of the belt filter press are high. Although the methods can dewater the sludge fished from the river course to achieve the effect of drying the sludge, the four dredging and dewatering methods have various defects, such as poor efficiency and mobility, and are not suitable for ordinary sludge dewatering.
