[0013] Example

[0014] refer to Figures 1 to 4This embodiment describes a wastewater treatment sludge discharge device, including a wastewater treatment tank 1. A sludge suction pipe 4 is fixedly connected to one side of the wastewater treatment tank 1, and a sludge discharge pump 3 is fixedly connected to one side of the sludge suction pipe 4. A sludge discharge pipe 5 is fixedly connected to the output end of one side of the sludge discharge pump 3. A power assembly 6 is fixedly connected to one side of the wastewater treatment tank 1, and an agitation assembly 7 is provided on one side of the wastewater treatment tank 1. A sludge concentration detector 41 is fixedly connected to one side of the sludge suction pipe 4, and a flow control valve 51 is fixedly connected to the output end of the sludge discharge pump 3. The sludge suction pipe 4 draws in the sludge suspension formed in the wastewater treatment tank 1. The sludge concentration detector 41 detects the sludge concentration in the sludge suction pipe 4 in real time and feeds the data back to the external control system. The sludge discharge pump 3 starts to provide power for sludge discharge and transports the sludge suspension to the sludge discharge pipe 5. The operator adjusts the sludge discharge flow rate through the flow control valve 51 according to the sludge concentration data to meet the requirements of different treatment conditions, thereby improving the applicability of the sludge discharge device and the wastewater treatment efficiency.

[0015] refer to Figure 2 and Figure 4 The power assembly 6 includes a drive motor 61, which is located on the upper side of the wastewater treatment tank 1. The output end of the drive motor 61 is fixedly connected to a first drive shaft 62. A second drive shaft 65 is rotatably connected to one side of the first drive shaft 62 on the wastewater treatment tank 1. The agitation assembly 7 is fixedly connected to the second drive shaft 65. A first toothed cone 63 is fixedly connected to one side of the first drive shaft 62, and there are two first toothed cones 63. A second toothed cone 64 is meshed with one side of the first toothed cone 63, and the second toothed cone 64 is fixedly connected to the second drive shaft 65. By setting the power assembly 6, the drive motor 61 drives the first drive shaft 62 to rotate, the first drive shaft 62 drives the two first toothed cones 63 to rotate, the first toothed cones 63 drive the second toothed cones 64 to rotate, and the second toothed cones 64 drive the second drive shaft 65 to rotate, providing power to the agitation assembly 7. The setting of two first toothed cones 63 can realize the synchronous driving of multiple agitation assemblies 7, ensuring the uniformity of sludge treatment in the wastewater treatment tank 1.

[0016] refer to Figure 2The agitation assembly 7 includes a transmission stirring rod 71, which is fixedly connected to the second drive shaft 65. The transmission stirring rod 71 is rotatably connected to the inside of the wastewater treatment tank 1. A spiral blade 73 is fixedly connected to one side of the transmission stirring rod 71, and a stirring blade 72 is fixedly connected to the side of the transmission stirring rod 71 away from the spiral blade 73. By setting the agitation assembly 7, the rotation of the second drive shaft 65 drives the transmission stirring rod 71 to rotate. The spiral blade 73 and the stirring blade 72 on the transmission stirring rod 71 rotate accordingly. During the rotation, the spiral blade 73 transports and stirs the sludge from the outside in, while the stirring blade 72 breaks up and mixes the sludge in all directions, so that the clumped sludge forms a uniform sludge suspension, which is convenient for subsequent suction pipe 4 to pick up, improves the thoroughness of sludge discharge, and ensures the sewage treatment effect.

[0017] refer to Figure 1 The wastewater treatment tank 1 is fixedly connected to a feed hopper 2 on the side away from the sludge suction pipe 4. The inner wall of the feed hopper 2 is inclined. Wastewater enters the wastewater treatment tank 1 through the feed hopper 2. Due to the inclination of the inner wall of the feed hopper 2, the wastewater can flow smoothly into the wastewater treatment tank 1 for wastewater treatment.

[0018] refer to Figure 3 A protective shell 8 is fixedly connected to one side of the first drive shaft 62 on the wastewater treatment tank 1. The first drive shaft 62 is rotatably connected to the protective shell 8. By setting the protective shell 8, most of the structure of the power assembly 6 is protected, and the connection is sealed to prevent external debris from entering.

[0019] Operating principle and advantages: Wastewater enters the wastewater treatment tank 1 through the feed hopper 2. The inclined design of the inner wall of the feed hopper 2 ensures smooth flow of wastewater. After entering the wastewater treatment tank 1, the drive motor 61 of the power component 6 starts, driving the first drive shaft 62 to rotate. Through the meshing transmission of the first toothed cone 63 and the second toothed cone 64, the second drive shaft 65 is driven to rotate. The stirring component 7 connected to the second drive shaft 65 operates accordingly. During the rotation, the spiral blades 73 transport and stir the external sludge inward, while the stirring blades 72 thoroughly disperse and mix the sludge. The process involves combining clumped sludge to form a uniform sludge suspension, facilitating subsequent suction by the sludge suction pipe 4, improving the thoroughness of sludge removal, and ensuring the effectiveness of wastewater treatment. The design of two first toothed cones 63 enables multiple agitation components 7 to work simultaneously, ensuring uniform sludge treatment. The sludge suction pipe 4, under the action of the sludge discharge pump 3, draws in the suspension. The sludge concentration detector 41 monitors the sludge concentration in real time and feeds it back to the control system. The control system automatically adjusts the flow control valve 51 based on the concentration data to precisely control the sludge discharge flow rate. This process achieves intelligent sludge discharge, adapting to different treatment conditions and avoiding energy waste.
