DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] Based on the problem that the existing technology only dehydrates the sludge but does not purify the parasite eggs, pathogenic microorganisms, etc. in the sludge, this embodiment provides a sludge treatment equipment for water conservancy projects, please refer to Figure 1-Figure 5 The embodiment provides a sludge treatment device for water conservancy projects, which can deeply purify sludge and prevent sludge from polluting the environment. The sludge treatment device for water conservancy projects includes a separation tank 2 mounted on the left side of a treatment tank 1. The treatment tank 1 is provided with a treatment mechanism 3 for purifying the sludge. The separation tank 2 is provided with a separation mechanism 4 for separating the sludge into solids and liquids. The sludge in the treatment tank 1 is purified by the treatment mechanism 3, and then the sludge is separated into solids and liquids by the separation mechanism 4 in the separation tank 2.

[0027] Since the prior art only dehydrates the sludge without purifying the parasite eggs, pathogenic microorganisms, etc. in the sludge, the device is provided with a processing mechanism 3, which includes a stirring shaft 301 rotatably connected to the inside of the processing box 1, and a plurality of stirring rods 302 and a turning screw 303 are vertically and equidistantly installed on the stirring shaft 301. The stirring rods 302 and the turning screw 303 are staggeredly installed on the stirring shaft 301, and a transmission member 304 is installed on the top of the stirring shaft 301. The top of the processing box 1 is provided with a driving transmission member 304. The driving motor 305 rotates, and the aeration assembly 306 for aerating the treatment box 1 is provided on the stirring shaft 301. When the driving motor 305 is started, the stirring shaft 301 is rotated, which in turn drives the stirring rod 302 on the stirring shaft 301 to rotate to mix and stir the sludge and the purifying agent, so that the two are fully contacted and reacted to purify the sludge. During the stirring process, the auger 303 twists the sludge at the bottom of the treatment box 1 upward, and cooperates with the stirring rod 302 to achieve comprehensive mixing and stirring, further improving the efficiency of the purification reaction.

[0028] When sludge is purified by microorganisms, it is necessary to inject oxygen into the sludge to accelerate the decomposition of organic matter in the sewage. Therefore, the device is also provided with an aeration component 306, which includes an air inlet channel 3061 opened in the stirring shaft 301 and the stirring rod 302, and the air inlet channels 3061 in the stirring shaft 301 and the stirring rod 302 are connected. An aeration hole 3062 is opened on the stirring rod 302 and is connected to the air inlet channel 3061. A check valve 3063 is installed in the aeration hole 3062. A booster air intake pump 3064 is installed on the top of the treatment box 1, and its front end air intake pipe is installed on the top of the air inlet channel 3061 on the stirring shaft 301 through a bearing. When the booster air intake pump 3064 is started, air is injected into the air inlet channel 3061 on the stirring shaft 301 and the stirring rod 302 through the air intake pipe, and finally injected into the interior of the treatment box 1 through the aeration hole 3062, thereby accelerating the decomposition and purification of organic matter in the sewage.

[0029] A mud inlet pipe 307 is installed on the top right side of the treatment box 1, and an observation window 308 for observing the progress of sludge purification inside the treatment box 1 is installed on the front of the treatment box 1. Sludge, various chemical agents and microorganisms are injected into the interior of the treatment box 1 through the mud inlet pipe 307 for sludge purification. The purification process of the sludge inside the treatment box 1 can be observed in real time through the observation window 308.

[0030] Example 2

[0031] On the basis of Example 1, Figure 1-Figure 5As shown, after the sludge is purified, the sludge contains a lot of water, which is not convenient for subsequent treatment. Therefore, the sludge needs to be separated into solid and liquid. Therefore, the device is also provided with a separation mechanism 4, which includes a rotating shaft 401 rotatably connected to the inside of the separation tank 2, and an extrusion auger 402 is installed on the rotating shaft 401, and water filter holes 403 are evenly opened on the extrusion auger 402. A rotating motor 404 that drives the rotating shaft 401 to rotate is installed on the right side of the separation tank 2, and a conveying component 405 for conveying sludge is provided between the treatment box 1 and the separation tank 2. The left side of the separation tank 2 is a conical structure, with a discharge pipe 406 installed at the bottom, and a drain pipe 407 installed at the bottom of the right side of the separation tank 2. After the purified sludge is injected into the interior of the separation tank 2, the rotating motor 404 is started to drive the rotating shaft 401 to rotate, and then drive the extrusion auger 402 on the rotating shaft 401 to rotate, and the sludge is screwed to the left side of the separation tank 2. In this process, the sludge is compressed, and the compressed sludge blocks are discharged through the discharge pipe 406. The compressed sewage flows into the drain pipe 407 on the right side of the separation tank 2 through the water filter hole 403 and is discharged, thereby realizing the solid-liquid separation of the sludge.

[0032] The conveying component 405 includes a suction pump 4051 installed on the rear side of the separation tank 2. The suction port of the suction pump 4051 is installed with a suction pipe 4052, and the other end of the suction pipe 4052 extends into the interior of the treatment box 1. The discharge port of the suction pump 4051 is installed with an injection pipe 4053, and the other end of the injection pipe 4053 extends into the interior of the injection pipe 4053. When the suction pump 4051 is started, the purified sludge in the treatment box 1 is pumped to the injection pipe 4053 through the suction pipe 4052 and input into the interior of the separation tank 2, thereby completing the solid-liquid separation treatment of the sludge.
