Description

TECHNICAL FIELD

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

[0002] With the acceleration of urbanization and the improvement of industrialization, sewage treatment has become an important part of environmental protection. In this process, a large amount of sludge has brought great pressure to the environment. In order to effectively treat these sludge and reduce its impact on the environment, various sludge treatment equipment and technology have emerged. These devices and technologies not only help to reduce the volume of sludge and reduce transportation costs, but also improve environmental quality and promote sustainable development.

[0003] In the existing sludge treatment method, the most common means is to use the combination of mechanical dewatering and hot air drying. Specifically, mechanical dewatering usually uses filter press or centrifuge. The filter press uses high pressure to squeeze water out of the sludge to form a solid cake; the centrifuge uses centrifugal force generated by high-speed rotation to separate water. Both methods can effectively achieve solid-liquid separation and lay the foundation for further drying treatment.

[0004] Although the above method solves the problem of sludge dewatering to some extent, there are still obvious deficiencies in actual application. In particular, for high-moisture or high-viscosity sludge, the dewatering effect of traditional filter press and centrifuge is often unsatisfactory. This kind of sludge is easy to adhere to the inside of the equipment, which leads to the gradual decrease of the processing space, and the accumulated water also causes corrosion inside the equipment, which may cause damage to the equipment in severe cases. CONTENT OF THE INVENTION

[0005] In order to effectively prevent the equipment from rusting due to water accumulation, the present application provides a quick drying device of a sludge dewatering machine.

[0006] The quick drying device of the sludge dewatering machine provided by the present application adopts the following technical scheme:

[0007] A quick drying device of a sludge dewatering machine, comprising a machine body, a dewatering mechanism and a drying mechanism are arranged in the machine body, the dewatering mechanism comprises a water collecting tank, a rotating drum and a spiral conveyor, the water collecting tank is arranged in a cylindrical shape, a drain groove is concavely arranged at the bottom of the water collecting tank, and a drain pipe penetrating the machine body is connected to the bottom of the drain groove, the rotating drum is coaxially arranged in the water collecting tank, the wall of the rotating drum is provided with uniformly distributed dewatering holes, and a water scraping strip is arranged on the outer side wall of the rotating drum along the axial direction of the rotating drum, the free end of the water scraping strip abuts against the inner side wall of the water collecting tank, the spiral conveyor is coaxially arranged in the rotating drum, there is a gap between the blade of the spiral conveyor and the inner wall of the rotating drum, the rotating direction of the spiral conveyor is the same as that of the rotating drum, the rotating speed of the spiral conveyor is lower than that of the rotating drum, and the machine body is respectively connected with the spiral conveyor at both ends to form an inlet pipe and an outlet pipe.

[0008] By adopting the technical scheme, the sludge to be treated is sent into the rotating drum from the feeding pipe, the motor of the rotating drum and the screw conveyor is started, the rotating drum rotates at high speed, the dewatering of the sludge is started, the screw conveyor rotates at a slightly slow speed, the sludge is stirred and dispersed, and the dewatered sludge is pushed to the discharge port. In this process, the water separated from the sludge flows to the drainage groove at the bottom of the water collecting tank through the dewatering holes on the wall of the rotating drum, and then is discharged from the body through the drain pipe. The low-speed rotation of the screw conveyor not only can effectively stir and disperse the sludge, but also can ensure that the dewatered sludge is smoothly discharged. The water collecting tank can effectively collect the water in the sludge and discharge the water from the body through the drain pipe. In the process of high-speed rotation of the rotating drum, the water accumulated on the inner wall of the water collecting tank is scraped into the drainage groove by the water scraping strip, further reducing the accumulation of water on the inner wall of the water collecting tank, reducing the risk of equipment rust, and prolonging the service life of the equipment.

[0009] Optionally, the drying mechanism comprises a warm air blower, an air inlet of the warm air blower is in communication with the inside of the water collecting tank, and an air outlet hole is further formed in the water collecting tank and covered with a water-proof and air-permeable film.

[0010] By adopting the technical scheme, the air inlet of the warm air blower is in communication with the inside of the water collecting tank, so that the warm air can directly enter the inside of the water collecting tank to accelerate the evaporation of the water in the sludge. At the same time, the water-proof and air-permeable film covering the air outlet hole can effectively block the water from being discharged from the water collecting tank, keep the inside of the body dry, and prolong the service life of the equipment.

[0011] Optionally, the drying mechanism further comprises an activated carbon filter and an air extractor, an air outlet is formed in the side wall of the body, the activated carbon filter is arranged at the air outlet, and the air extractor is arranged on the side of the activated carbon filter away from the body.

[0012] By adopting the technical scheme, in the process of sludge dewatering, the air blower of the warm air blower discharges the gas in the water collecting tank into the body, the gas is then extracted from the air outlet by the air extractor, and the activated carbon filter adsorbs and removes the odor and harmful substances in the gas, thereby significantly improving the air quality of the working environment.

[0017] Optionally, the feeding pipe is provided in a bucket shape at the top end extending out of the machine body.

[0018] By using the above technical scheme, the feeding pipe is provided in a bucket shape at the top end extending out of the machine body, which can significantly increase the effective area of the feeding port, thereby improving the speed and convenience of the sludge entering the dewatering machine. At the same time, this design can also reduce the possibility of sludge blocking during feeding, ensure continuous and stable working condition, and improve the operation efficiency of the entire device.

[0019] Optionally, a cover is arranged at the top of the feeding pipe, an elastic sealing sleeve ring is arranged around the circumference of the cover, a flange is arranged around the sidewall of the top end of the feeding pipe, and the elastic sealing sleeve ring is sleeved on the flange.

[0020] By using the above technical scheme, the cooperation of the elastic sealing sleeve ring and the flange enhances the sealing performance between the cover and the feeding pipe, which can effectively prevent the leakage of sludge from the feeding port during operation, and improve the overall reliability and safety of the equipment.
