Description

Technical Field

[0001] This utility model relates to the technical field of sludge dewatering equipment, and in particular to an integrated sludge deep dewatering machine. Background Technology

[0002] In today's society, the wastewater treatment industry is booming, which in turn generates a large amount of sludge. As a byproduct of wastewater treatment, sludge contains high levels of moisture, organic matter, microorganisms, and harmful substances. If not properly treated, it can cause serious harm to the environment, such as polluting soil and water bodies, emitting foul odors, and affecting air quality.

[0003] In sludge treatment, dewatering is a crucial step. Traditional sludge dewatering equipment is often single-function, with cumbersome processes requiring multiple independent units to operate simultaneously. This not only increases the equipment's footprint and investment costs but also makes it prone to secondary pollution during sludge transfer between different units, while reducing treatment efficiency. Furthermore, traditional equipment suffers from poor mixing and agitation in the mixing and stirring stages, making it difficult to thoroughly and evenly mix the sludge with the chemicals, thus affecting subsequent dewatering. In the dewatering stage, the low dewatering efficiency prevents deep dewatering of the sludge, resulting in sludge with a still high moisture content after dewatering, which is detrimental to subsequent transportation and disposal. Utility Model Content

[0004] To address some of the problems existing in the prior art, this utility model provides an integrated sludge deep dewatering machine. By optimizing the stirring structure of the mixing system and the dewatering principle of the filtration system, this utility model enables the sludge and the agent to be fully mixed, effectively improving the dewatering efficiency, achieving deep dewatering of the sludge, and reducing the sludge volume.

[0005] To achieve the above objectives, this utility model provides an integrated sludge deep dewatering machine, including a sludge dewatering machine body. The sludge dewatering machine body includes a support base, a main body is arranged above the support base, a mixing system is arranged on one side of the main body, a filtration system is arranged on the other side of the main body, a sewage transport pipeline is arranged between the mixing system and the filtration system, a filtrate discharge port is arranged below the main body, and a sludge cake output port is arranged below the filtration system.

[0006] As a further improvement of this utility model, in order to enhance the stability of the sewage mixing tank and ensure that it will not shift or be damaged due to vibration or other reasons during operation, the mixing system includes a sewage mixing tank. A bearing plate is provided between the bottom of the sewage mixing tank and the supporting base. The bearing plate is fixed by screws. A double-ended pipeline is provided at the bottom of the sewage mixing tank. A sludge conveying port is provided in conjunction with the double-ended pipeline. A chemical dosing branch pipe is provided on one side of the sludge conveying port. A return pipe is also provided on one side of the double-ended pipeline. A water supply pipe is also provided on one side of the sewage mixing tank.

[0007] As a further improvement of this utility model, in order to fully mix sewage, sludge and chemicals in the tank, improve the mixing uniformity and ensure that the chemicals can play a full role, a stirring system is provided on the top of the sewage mixing tank of the mixing system. The stirring system includes a stirring drive motor, a stirring fixing seat is provided between the stirring drive motor and the top of the sewage mixing tank, and a stirring shaft is connected to the bottom of the stirring drive motor.

[0008] As a further improvement of this utility model, in order to crush large sludge particles entering the sewage mixing tank and prevent them from clogging subsequent treatment equipment, several sets of crushing shafts are provided on the stirring shaft, and a fixing block is provided between the crushing shaft and the stirring shaft. The adjacent crushing shafts are arranged at an angle of 30-90°.

[0009] As a further improvement of this utility model, in order to further enhance the mixing effect and ensure that the sewage, sludge and reagents are fully and evenly mixed, at least two layers of stirring blades are provided below the crushing shaft on the stirring shaft, and the stirring blades are turbine blades.

[0010] As a further improvement of this utility model, in order to gradually increase the squeezing pressure on the sludge during the sludge transportation process, so that the water in the sludge is continuously squeezed out and the dewatering effect is improved, the filtration system is set on the main body at a 30-60 degree angle. The filtration system includes a support box, a stacked screw shaft is set inside the support box, and a stacked screw drive motor is set outside the support box. The stacked screw drive motor is connected to the stacked screw shaft. A dewatering shell is fitted outside the stacked screw shaft. Spiral blades are arranged around the stacked screw shaft inside the dewatering shell. The pitch of the spiral blades gradually decreases along the sludge transportation direction. The bottom of the dewatering shell is connected to the filtrate discharge port.

[0011] In operation, sludge and chemicals enter the wastewater mixing tank of the mixing system through the sludge conveying port and the chemical dosing branch pipe, respectively. The stirring system then begins operation; the stirring drive motor, supported by the stirring base, drives the stirring shaft to rotate. The crushing shaft on the stirring shaft rotates accordingly. Because adjacent crushing shafts are set at an angle of 30-90°, large particles of sludge entering the tank can be effectively crushed, preventing them from clogging subsequent equipment.

[0012] The crushed sludge and chemicals continue to mix within the tank, where at least two layers of turbine-type agitator blades below the stirring shaft play a crucial role. These turbine blades generate powerful agitation, ensuring thorough and uniform mixing of the wastewater, sludge, and chemicals. This guarantees sufficient contact and reaction between the chemicals and sludge, accelerating the separation of water from the sludge and preparing it for subsequent dewatering.

[0013] The uniformly mixed sludge enters the filtration system through the wastewater transport pipeline. The filtration system is positioned at a 30-60° angle on the main body, utilizing gravity to assist sludge transport. The screw press drive motor starts, rotating the screw shaft within the support housing. Inside the dewatering shell fitted outside the screw shaft, spiral blades arranged around the screw shaft rotate accordingly, with the pitch of the spiral blades gradually decreasing along the sludge transport direction. During sludge transport, the decreasing pitch gradually increases the compressive pressure on the sludge, continuously squeezing out water and achieving efficient dewatering. The filtrate produced during dewatering collects at the bottom of the dewatering shell and is discharged through the filtrate outlet for further treatment. The dewatered sludge is discharged from the sludge cake outlet of the filtration system, completing the entire deep sludge dewatering process.

[0014] The beneficial effects of this utility model are as follows:

[0015] Compact and reasonable structure: This integrated sludge deep dewatering machine integrates the mixing system, main body and filtration system into one unit, making the overall structure compact, saving space, and facilitating installation and transportation. It also benefits the overall management and maintenance of the equipment.

[0016] Excellent mixing effect: The mixing system is equipped with a sewage mixing tank, and the sludge and the agent are fully mixed through the stirring system. This increases the shearing and crushing force during the stirring process, effectively breaking up large particles in the sludge and improving the uniformity of the mixing of sludge and the agent. The stirring blades adopt turbine blades, which further enhance the stirring effect and ensure thorough mixing.

[0017] High dewatering efficiency: The dewatering shell is equipped with spiral blades around the stacked screw shaft, and the pitch of the spiral blades gradually decreases along the sludge conveying direction. This causes the sludge to be subjected to gradually increasing extrusion pressure during the conveying process, thereby effectively improving the dewatering efficiency, fully squeezing out the water from the sludge, and achieving deep dewatering of the sludge.
