Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment devices, in particular to sludge treatment equipment for river management. Background Art

[0002] River sludge is a complex substance, including soil, plant waste, biological residues, suspended matter and human waste. As time goes by, the sludge in the river will affect the movement of water and the health of the ecological environment. Therefore, regular dredging of the river is an important river management measure.

[0003] There are three main ways to clean river sludge: mechanized cleaning, manual cleaning, and ecological cleaning. Regardless of the cleaning method, a mixture of solid and liquid will be obtained. As people's environmental awareness increases, resource utilization is the main treatment method. During the resource utilization process, due to the complex biological composition of river sludge, it is difficult to directly perform biological treatment on it. In order to facilitate the subsequent biological treatment of river sludge, the river sludge is currently first disinfected to ensure its effective utilization in the future.

[0004] The sludge disinfection treatment and drying process are carried out simultaneously. Due to the high content of viscous components in the sludge, agglomeration usually occurs during the drying process, resulting in low drying efficiency and slightly poor disinfection treatment. It can be seen that it is of great significance to provide a drying equipment that can minimize sludge agglomeration. Summary of the invention

[0005] In view of this, the utility model provides a sludge treatment device for river management, specifically a sludge treatment device provided with a tank body and a separator, and a stirring rod and a scraper are provided in the tank body. The sludge treatment device has the advantages of strong practicality, reasonable design and convenient use. Using the device to treat sludge can effectively avoid sludge agglomeration, and is more conducive to drying and sterilizing the sludge.

[0006] On the basis of the existing technology, the utility model provides a sludge treatment device for river management, including a tank body and a separator;

[0007] The gas outlet on the side of the tank is connected to the separator; as the drying process proceeds, small particles in the sludge will be suspended in the tank, resulting in excessive dust concentration in the tank, causing excessive tank pressure and easily causing danger. Therefore, the above arrangement can quickly separate the suspended sludge particles, reduce the pressure in the tank, and improve safety in use;

[0008] The tank body is a hollow structure, and an electric heating device is installed inside the tank body to heat the gas in the tank body;

[0009] The tank body is arranged transversely, and a motor is arranged on one side of the tank body, the motor is connected to a rotating shaft, and the free end of the rotating shaft passes through the other side of the tank body and is located outside the tank body;

[0010] A stirring rod is provided on the rotating shaft, and a scraper is provided at the end of the stirring rod, and the end of the scraper is in contact with the inner wall of the tank body; when solid and liquid sludge are put into the tank body, the scraper picks up the sludge and makes it move in the tank body, and when the sludge is thrown up and falls downward, various substances in the sludge will fall at different levels due to different gravity, which is conducive to the hot air in the tank body to heat it and improve the drying efficiency; in addition, the throwing and falling movements can avoid sludge agglomeration to the greatest extent, improve the looseness of the sludge, and improve the sterilization effect.

[0011] Preferably, the separator is a cyclone separator.

[0012] Preferably, the stirring rods are staggered, which can improve stirring efficiency while reducing the number of scrapers.

[0013] Preferably, a pointed protrusion is provided on the rotating shaft, and when the lumpy sludge hung by the scraper falls onto the rotating shaft, the protrusion can break it up, further preventing the sludge from agglomerating.

[0014] Preferably, in order to further improve the drying efficiency, the rotating shaft is a hollow structure with one end open, and a vent is provided on the rotating shaft, in which a one-way valve is installed; the free end of the rotating shaft located outside the tank body is connected to an air compressor; gas is introduced into the rotating shaft through the air compressor, and the gas is introduced into the tank body after passing through the one-way valve, which can promote the gas flow in the tank body, improve the drying efficiency, and avoid agglomeration.

[0015] Compared with the prior art, the beneficial effect of the utility model is that by setting a separator connected to the tank body, dust and excessive pressure in the tank body can be avoided, thereby improving the safety of the tank body; by setting a hollow structure of the tank body and installing an electric heating device on the tank body, the gas temperature in the tank body is made more uniform, and under the condition of uniform heating, sludge agglomeration can be avoided as much as possible; by setting a stirring rod and a scraper, the sludge can be thrown, so that the sludge has different descending speeds when it falls, thereby avoiding sludge agglomeration and improving the looseness of the sludge. The above-mentioned settings make the sludge treatment equipment have the advantages of strong practicality, reasonable design and easy use. Using this equipment to treat sludge can effectively avoid sludge agglomeration and is more conducive to drying and sterilizing the sludge. BRIEF DESCRIPTION OF THE DRAWINGS
