Description

Technical Field

[0001] The utility model belongs to the field of sludge dewatering equipment, in particular to a sludge dewatering device for water conservancy project construction. Background Art

[0002] Sludge dewatering device is a device used to remove moisture from sludge. Sludge is usually a solid substance containing water produced during water treatment. It needs to be treated to reduce the moisture content, thereby reducing the volume and weight, and facilitating subsequent disposal or recycling.

[0003] According to Chinese patent application number: 202021037302.3, a sludge dewatering device is disclosed, including a support mechanism, and a power mechanism installed on the support mechanism for providing energy, and also including a discharge mechanism arranged on one side of the power mechanism and connected to the support mechanism for controlling the discharge of sludge. By utilizing the special shape of the auger shaft to squeeze and convey the sludge in the screen drum, it is separated from the water. The structure is simple, the operation is convenient, and the dryness and wetness of the filter cake after dehydration can be manually controlled, which is highly practical.

[0004] The comparative case effectively solves the problem of low treatment efficiency of the sludge dewatering device in the existing technology, and has the advantages of convenient operation and high sludge dewatering efficiency.

[0022] Example 1

[0023] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a sludge dewatering device for water conservancy project construction, including a coagulation tank 1.

[0027] In this embodiment, the stirring mechanism 2 includes a main shaft 201 , a stirring rod 202 and a connecting rod 203 . The stirring rod 202 is fixed to the surface of the main shaft 201 , and one end of the connecting rod 203 is fixedly connected to the main shaft 201 .

[0028] The driving mechanism 3 includes an installation box 301, a servo motor 302, a driving gear 303, a driven gear 304 and a support rod 305. The installation box 301 is fixed to the top of the coagulation tank 1. The driving gear 303, the driven gear 304 and the support rod 305 are all installed in the inner cavity of the installation box 301. The servo motor 302 is fixedly connected to the installation box 301.

[0029] The output shaft of the servo motor 302 passes through the inner cavity of the installation box 301 and is transmission-connected to the driving gear 303 , which is meshed with the driven gear 304 . The other end of the connecting rod 203 passes through the inner cavity of the installation box 301 and is fixedly connected to the driven gear 304 .

[0030] like Figure 1 and 2 As shown, the output shaft of the servo motor 302 rotates to drive the driving gear 303 to rotate, and when the driving gear 303 rotates, it drives the driven gear 304 to rotate. When the driven gear 304 rotates, the support rod 305 can support it. When the driven gear 304 rotates, it drives the main shaft 201 to rotate through the connecting rod 203.

[0031] Example 3

[0032] Reference Figure 1 、 3 and 4, which are the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

One end of the conveying pipe 503 is connected to the output end of the high-pressure plunger pump 501, one end of the connecting pipe 502 is connected to the coagulation tank 1, and the other end of the connecting pipe 502 is connected to the input end of the high-pressure plunger pump 501.

[0035] like Figure 1 、 3 As shown in Figure 4, the drug inlet pipe 402 is connected to the external drug dosing tank. The centrifugal force generated by the high-speed rotation of the drug dosing pump 401 drives the flocculant into the inner cavity of the coagulation tank 1 through the drug inlet pipe 402 and the drug delivery pipe 403.
