Description

Technical Field

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

[0002] Sludge dewatering is a sludge treatment method that removes water from flowing primary, concentrated or digested sludge and converts it into semi-solid or solid mud blocks. After dehydration, the moisture content of the sludge can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dehydration equipment. Further dehydration of sludge is called sludge drying, and the moisture content of dried sludge is less than 10%. The main methods of dehydration are natural drying, mechanical dehydration and granulation. Natural drying and mechanical dehydration are suitable for sewage sludge, and granulation is suitable for coagulated and precipitated sludge.

[0003] In the prior art, for example, the Chinese patent announcement number: CN215627544U discloses a sludge dewatering treatment device, comprising: a dewatering box, the lower surface of which is fixedly connected with a drainage pipe interconnected with the dewatering box; a mounting plate, the mounting plate is rotatably connected with the inner bottom wall of the dewatering box; a motor for driving the mounting plate to rotate is mounted on the outer surface of the dewatering box; a desludging net mechanism with an auxiliary drainage function, the desludging net mechanism with an auxiliary drainage function is connected to the mounting plate. The sludge dewatering treatment device provided by the utility model has the advantages of improving the speed and quality of sludge dewatering.

[0004] However, when this device is in use, the desludging net mechanism is only installed on the surface of the mounting plate, and lacks support for the desludging net mechanism. Long-term rotation may cause the desludging net mechanism to shake, and the shaking of the desludging net will cause the guide rod to move, thereby making the gear and gear ring mechanism unable to engage, causing the entire device to be scrapped; and, although the guide rod can increase the speed and quality of sludge dewatering, when the sludge is dehydrated, the dehydrated sludge will adhere to the inside of the desludging net mechanism, which is inconvenient to clean the inside, thereby interfering with the reuse of the device. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sludge dewatering treatment equipment, comprising: a treatment barrel, a plurality of supporting legs are fixedly installed on the outer wall surface of the treatment barrel, a water outlet is installed on one side surface of the outer wall of the treatment barrel, a centrifugal component is provided on the inner wall surface of the treatment barrel, and a sludge scraping component is provided on the top surface of the treatment barrel.

[0007] As a preferred embodiment, the centrifugal assembly includes a hollow ring, which is fixedly mounted on the inner wall surface of the processing barrel, the interior of the hollow ring is slidably connected with a ring, a dehydration barrel is fixedly mounted on the inner wall surface of the ring, and a plurality of dehydration holes are provided on the surface of the dehydration barrel.

[0008] As a preferred embodiment, the bottom inner wall surface of the processing barrel is connected to a rotating rod via a bearing, and the top surface of the rotating rod is fixedly connected to the dehydration barrel.

[0009] As a preferred embodiment, a first gear is fixedly mounted on the surface of the rotating rod, a U-shaped plate is fixedly mounted on the bottom surface of the processing barrel, a rotating motor is fixedly mounted on the surface of the U-shaped plate, a second gear is fixedly mounted on the output end of the rotating motor, and the second gear and the first gear are meshed with each other.

[0010] As a preferred embodiment, the scraper assembly includes two support frames, and the two support frames are symmetrically fixed on the top surface of the processing barrel, a threaded rod is connected between the inner walls at both ends of one of the support frames through bearings, and a forward and reverse motor is fixedly installed on the top surface of one of the support frames, and the output end of the forward and reverse motor is fixedly connected to one end of the threaded rod.

[0011] As a preferred embodiment, a long rod is fixedly installed between the inner walls at both ends of the other support frame, a scraper plate is threadedly connected to the surface of the threaded rod, the scraper plate slides with the help of the threaded rod and the long rod, and a stirring rod is fixedly installed on the top surface of the scraper plate.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. The utility model sets a centrifugal assembly. When the sludge needs to be dehydrated, the sludge is first added into the dehydration barrel, and then the rotary motor is operated by the external controller. The rotary motor drives the rotating rod to rotate, and the rotating rod drives the dehydration barrel to rotate. The dehydration barrel drives the ring to rotate inside the hollow ring. At the same time, the dehydration barrel rotates to generate centrifugal force. The dehydration barrel rotates to generate centrifugal force, so that the water in the sludge is thrown out from the dehydration hole through the action of the centrifugal force. The thrown water is stored in the processing barrel. At the same time, the dehydration barrel drives the sludge to rotate, and the sludge is relative to the stirring barrel. The stirring rod is rotating, so that the stirring rod stirs the sludge, which increases the fluidity of the sludge and makes it easier to throw out the water in the sludge. The water outlet is opened by an external controller. Since the bottom inner wall surface of the treatment barrel is inclined, the thrown-out water flows out from the water outlet, thereby completing the sludge dehydration process. Through the cooperation of the above structure, the dehydration barrel rotates inside the hollow ring driven by the rotating rod, thereby making the dehydration barrel rotate more stably for a long time, and the sludge is dehydrated more stably, thereby improving the service life of the device.

[0014] 2. The utility model provides a scraper assembly. When the sludge needs to be cleaned after the sludge dehydration treatment is completed, the forward and reverse motors are first operated through the external controller. The operation of the forward and reverse motors drives the threaded rod to rotate. The rotation of the threaded rod drives the scraper plate to move upward on the surface of the long rod. The scraper plate moves upward on the surface of the long rod to scrape the sludge inside the dehydration barrel. When the scraper plate reaches a suitable position, the forward and reverse motors can be stopped. The sludge on the surface of the scraper plate can be cleaned. Through the cooperation of the above-mentioned structure, the sludge can be prevented from sticking to the inner wall surface of the dehydration barrel, and the sludge inside the dehydration barrel can be cleaned conveniently.
