[0027] Reference Figures 1-4 The utility model provides a desludging machine for sewage treatment, comprising:

[0028] The main unit 100 includes a separation cylinder 101, a feed pipe 102 is installed on the upper side of the separation cylinder 101, a base frame 103 is installed on the lower side of the separation cylinder 101, and a control switch 104 is installed on one side of the base frame 103, a drainage pipe 105 is fixedly connected to the lower side of the separation cylinder 101, and a mud discharge pipe 106 is fixedly connected to one side of the separation cylinder 101;

[0029] The active unit 200 includes a motor 201 fixedly connected to the separation cylinder 101. The motor 201 is electrically connected to the control switch 104. The output shaft of the motor 201 is fixedly connected to a rotating shaft 202. A first runner 204 is fixedly connected to the surface of the rotating shaft 202. A spiral blade 203 is arranged inside the separation cylinder 101, and the spiral blade 203 is fixedly connected to the rotating shaft 202, which has the function of sludge dewatering. A second runner 205 is arranged below the first runner 204, and the second runner 205 is movably connected to the first runner 204 through a transmission belt 206. The inner wall of the second runner 205 is rotatably connected to the surface of the sludge discharge pipe 106 through a bearing. Four connecting rods 207 are fixedly connected to one side of the second runner 205, and a sludge cleaning component 208 is detachably connected to the other end of each connecting rod 207. The sludge cleaning component 208 includes a connecting ring 208a rotatably connected to the sludge discharge pipe 106 through a bearing. A connecting block 208b is fixedly connected to the inner wall of the connecting ring 208a. A spiral blade 208c is fixedly connected to the inner side of the connecting block 208b, and the outer side of the spiral blade 208c is movably connected to the inner wall of the sludge discharge pipe 106. The rotation of the connecting ring 208a can drive the spiral blade 208c to rotate, so that the spiral blade 208c rotates inside the sludge discharge pipe 106, avoiding blockage inside the sludge discharge pipe 106. A plurality of first screw holes are formed on the surface of the connecting ring 208a, and bolts 209 are rotatably connected to the inside of each first screw hole through threads. Each bolt 209 is rotatably connected to the connecting rod 207 through threads. By rotating the bolt 209 through threads, the sludge cleaning component 208 can be flexibly detached from the surface of the sludge discharge pipe 106. The spiral blade 208c is designed in a spiral shape. The inner side of the spiral blade 208c is designed in an acute angle, and the outer side of the spiral blade 208c is designed in an arc shape matching the inner wall of the sludge discharge pipe 106. Through the spiral design, the spiral blade 208c guides the sludge to the outside of the sludge discharge pipe 106 while rotating. The acute angle design can enable the spiral blade 208c to break the sludge quickly, making the discharge of the sludge smoother.

[0030] Furthermore, the mutually approaching sides of each group of connecting rods 207 are designed in an arc shape matching the outer surface of the sludge discharge pipe 106. Each group of connecting rods 207 is slidably connected to the outer wall of the sludge discharge pipe 106, facilitating the sliding of the connecting rods 207 on the surface of the sludge discharge pipe 106 and reducing the wear on the surface of the sludge discharge pipe 106.

The twisting grooves can increase the friction force for controlling the twisting block, facilitating the rotation of the bolt 209 through threads.

[0032] During use, the motor 201 is started by operating the control switch 104 to drive the rotating shaft 202 to rotate. While the rotating shaft 202 drives the spiral blade 203 to rotate for operating on the water-carrying sludge, the first runner 204 fixedly connected to the rotating shaft 202 drives the second runner 205 to rotate on the surface of the sludge discharge pipe 106 through the transmission belt 206. The connecting rod 207 fixedly connected to the second runner 205 drives the connecting ring 208a to rotate. At the same time, the connecting ring 208a drives the connecting block 208b to rotate on the surface of the sludge discharge pipe 106. The spiral blade 208c fixedly connected to the connecting block 208b rotates inside the sludge discharge pipe 106. With the acute angle design, the spiral blade 208c cuts the sludge and guides the sludge to the outside of the sludge discharge pipe 106 under the action of the spiral design, so that the spiral blade 208c can not only avoid blockage inside the sludge discharge pipe 106 during rotation, but also accelerate the sludge discharge speed.
