Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a sludge dewatering and drying treatment device for sewage treatment. Background Art

[0002] During the sewage treatment process, a large amount of sludge is generated. With the increasing global emphasis on environmental protection and the increasingly strict sewage discharge standards, the sewage treatment volume is continuously increasing. For example, in urban sewage treatment plants, after the sewage undergoes a series of physical, chemical, and biological treatment processes, pollutants such as suspended solids and organic matter are aggregated to form sludge. These sludges usually contain a large amount of water, have a large volume, and have complex compositions, including microorganisms, organic debris, inorganic particles, etc. From an environmental protection perspective, if the sludge that has not been effectively dewatered and dried is randomly stacked or disposed of, it will cause serious pollution to the soil, water body, and atmospheric environment. For example, during the stacking process of sludge with a high water content, the pollutants in it may seep into the groundwater along with the leachate, polluting the groundwater resources. At the same time, the sludge will produce malodorous gases during the decomposition process, affecting the living environment of the surrounding residents. With the continuous increase in sludge production and the continuous improvement of environmental protection regulations, the requirements for sludge dewatering and drying treatment equipment are also getting higher and higher.

[0003] When the existing device separates sewage from sludge, it is unable to conveniently make the sludge adhering to the inner wall of the centrifuge cylinder fall off, thereby affecting the separation efficiency of sewage and sludge, and at the same time, it is not convenient to discharge the sludge inside the centrifuge cylinder.

[0020] The present invention provides a sludge dewatering and drying treatment device for sewage treatment. It has the following beneficial effects:

[0021] 1. For this sludge dewatering and drying treatment device for sewage treatment, through the installation of the dewatering device, the sewage to be treated is poured into the centrifugal cylinder from the feed pipe. Then, the first drive motor is started. The rotation of the output end of the first drive motor drives the centrifugal cylinder to rotate, so that the sewage entering the centrifugal cylinder is thrown out from the centrifugal holes of the centrifugal cylinder by centrifugal force.

Then the electric telescopic rod can be turned off. When the second driving motor drives the arc-shaped scraper to rotate, the centrifugal cylinder is in a static state. Then the rotating arc-shaped scraper can be used to scrape the sludge adhering to the inner wall of the centrifugal cylinder, causing the sludge adhering to the inner wall of the centrifugal cylinder to fall off, and improving the efficiency of sludge discharge inside the centrifugal cylinder.

[0023] 3. For this sludge dewatering and drying treatment equipment for sewage treatment, through the installation of the arc-shaped scraper, when the centrifugal cylinder separates the sludge, the electric telescopic rod is used to retract the arc-shaped scraper attached to one side of the inner wall of the centrifugal cylinder, avoiding the arc-shaped scraper from always contacting the rotating centrifugal cylinder and being worn. When it is necessary to clean the sludge on the inner wall of the centrifugal cylinder, the arc-shaped scraper is moved to the inner wall of the centrifugal cylinder. This effectively improves the service life of the arc-shaped scraper.

[0024] 4. For this sludge dewatering and drying treatment equipment for sewage treatment, through the installation of the drying device, the sludge enters the inside of the drying cylinder from the discharge nozzle and then falls on the conical plate. When the sludge is falling, it can slide from the top of the conical plate to the bottom of the conical plate. During the process of the sludge sliding along one side of the conical plate, the electric heating wire in the annular heating tube can conduct heat to the conical plate through the heat conduction plate, and then dry and heat the sliding sludge. The sludge can be spread out on the conical plate when it falls and slides on the conical plate, effectively increasing the contact area with the heated conical plate. And when the discharge nozzle discharges the sludge, the first driving motor can drive the centrifugal cylinder to rotate, and the centrifugal cylinder can drive the discharge nozzle to rotate. The discharge nozzle can rotate on the drying cylinder through the annular sealing plate, and the discharge nozzle can discharge the sludge to different positions on the conical plate, effectively improving the uniformity of sludge falling and further enhancing the drying efficiency.

[0050] During use, the operator pours the sewage to be treated into the centrifugal cylinder 31 from the feed pipe 33, and then starts the first driving motor 36. The rotation of the output end of the first driving motor 36 drives the centrifugal cylinder 31 to rotate, so that the sewage entering the centrifugal cylinder 31 is thrown out from the inside of the centrifugal holes of the centrifugal cylinder 31 by centrifugal force.

When it is necessary to clean the sludge on the inner wall of the centrifugal cylinder 31, the arc-shaped scraper 3910 is moved to the inner wall of the centrifugal cylinder 31, effectively improving the service life of the arc-shaped scraper 3910. And when the fixed cylinder 399 drives the arc-shaped scraper 3910 to scrape the sludge, the electric heating wire inside the fixed cylinder 399 can be turned on, and the heated arc-shaped scraper 3910 can be used to dry the adhered sludge through heat conduction. The sludge enters the drying cylinder 41 from the discharge nozzle 34 and then falls on the conical plate 43. When the sludge falls, it can slide from the top of the conical plate 43 to the bottom of the conical plate 43. During the process of the sludge sliding along one side of the conical plate 43, the electric heating wire in the annular heating pipe 44 can conduct heat to the conical plate 43 through the heat conduction plate, and then dry and heat the sliding sludge. When the sludge falls and slides on the conical plate 43, it can be spread out on the conical plate 43, effectively increasing the contact area with the heated conical plate 43.
