[0029] A separation assembly 2 is provided on one side of the bottom of the sedimentation tank 1, and a stirring assembly 3 is provided on the top of the extension plate 101;

[0030] The separation assembly 2 includes an outlet pipe 201, which is fixedly connected to one side of the bottom of the sedimentation tank 1. A filter screen cartridge 202 is fixedly connected to the bottom of the outlet pipe 201. A bent connecting rod 204 is fixedly connected to the outside of the other end of the filter screen cartridge 202.

[0031] Among them, the control chamber 205 is internally rotatably installed with a turntable 209, and the turntable 209 is engaged with a positioning disk 211.

The pause in each rotation of the driven gear 215 provides a time interval for the extrusion and discharge of the sludge.

[0032] The middle part of the rotary disk 209 is fixedly connected to a limit notch ring, and the edge of the rotary disk 209 is fixedly connected to a shift post 210.

A valve is installed on the outlet pipe 201; the valve is existing technology and will not be blocked by sewage and silt.

[0035] The stirring assembly 3 includes a fixed shell 301, the internal rotation of the fixed shell 301 is connected to the driving column 302, the acceleration column 303 and the driving shaft 304, the outside of the driving column 302 is fixedly connected to the driving gear 305, the outside of the acceleration column 303 is fixedly connected to the second gear 306 and the acceleration wheel 307, and the outside of the driving shaft 304 is fixedly connected to the rotating wheel 308; the driving gear 305 is meshed with the second gear 306, the diameter of the driving gear 305 is smaller than the second gear 306, a belt 309 is sleeved between the acceleration wheel 307 and the rotating wheel 308, the driving shaft 304 passes through the fixed shell 301 and the extension plate 101 and is symmetrically fixedly connected to the stirring member 310; the stirring member 310 includes a side plate that can scrape off the sludge; the diameter of the acceleration wheel 307 is smaller than the rotating wheel 308, and the fixed shell 301 is fixedly connected to the extension plate 101.

[0036] The driving shaft 304 is rotatably connected to the inner bottom surface of the sedimentation tank 1, and a dirt pushing rod 311 is fixedly connected to the outer side of the bottom of the driving shaft 304. The top of the fixed shell 301 is fixedly connected to the third motor 312, and the output end of the third motor 312 is fixedly connected to the driving column 302; the dirt pushing rod 311 can assist in pushing the sludge into the outlet pipe 201, so that the sludge enters the pushing range of the spiral blade 203 under gravity and water pressure, and the driving shaft 304 is located in the center of the sedimentation tank 1.

[0037] Working principle: Before using this sludge sedimentation and separation equipment, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 6 As shown, first open the valve on the outlet pipe 201 to allow impurities and sewage to flow into the outlet pipe 201. At this time, start the second motor 219 to make the spiral blade 203, thereby pushing the sludge to move and squeeze it with the blocking plate 206. During the squeezing process, the moisture content of the sludge decreases. The closer the sludge is to the blocking plate 206, the higher the density. At this time, the squeezed out moisture will flow out through the filter cylinder 202 to prevent the moisture during squeezing from making the sludge wet again. During this process, the driving motor 208 drives the rotary disk 209 to rotate, thereby causing the dial column 210 to be stuck in the positioning groove, causing the positioning disk 211 to rotate 90 degrees, thereby causing the transfer column 212 and the driving gear disk 213 to pass through the transfer column 212 and the driving gear disk 213. The driven gear 215 rotates the connecting plate 216 180 degrees through the rotating column 214, and then the connecting rod 217 pulls the moving rod 218 to move, and finally the blocking plate 206 moves away from the filter cylinder 202, so that the squeezed sludge has sufficient time to be pushed out of the filter cylinder 202 and then fall off along the guide inclined plate 207. After the sludge falls off, the blocking plate 206 will be reset and provide a barrier for subsequent sludge, so that the sludge can be better dehydrated, and finally the sludge can be quickly separated from the sewage in a waterless environment, ensuring the separation efficiency. In addition, the spiral blades 203 can prevent the sludge from clogging inside the filter cylinder 202.

[0038] By starting the third motor 312, the driving column 302 rotates, and then the rotation speed of the driving shaft 304 is accelerated through the driving gear 305, the second gear 306 and the acceleration wheel 307, the rotating wheel 308, and the belt 309, two sets of transmission structures, while avoiding the resistance of the sewage causing the third motor 312 to need to increase the output power so that the stirring element 310 can rotate quickly, and ultimately reduce the impact of the resistance on the output of the third motor 312, while ensuring the rotation speed of the stirring element 310, ensuring that the flocculant and other chemicals are fully mixed with the sewage.
