[0041] like Figure 1 , 2 As shown in FIG. 4 , according to an optional embodiment of the present invention, the water suction box 9 is made of stainless steel. Since the water suction box 9 is in contact with sludge and water for a long time, the stainless steel can prevent the water suction box 9 from being corroded.

[0042] like Figure 1 As shown, according to an optional embodiment of the present invention, a guide groove is provided on the guide plate 4, and the guide groove plays a drainage role to prevent the sludge from flowing out of the receiving tube 37.

[0043] A sludge treatment method based on a concentration component, using the sludge treatment system to treat sludge.

[0044] Implementation process:

[0045] Initially, one end of the lifting bar 8 lifts up the force-bearing convex plate 10 to keep the water suction box 9 at a certain height.

[0046] First, pour the sludge to the right side of the top wall of the conveyor belt device 2, turn on the conveyor belt device 2 to intermittently transfer the sludge to the left. When the conveyor belt is paused, turn on the motor 6 to drive the transmission plate 7 and the lifting bar 8 to rotate clockwise. One end of the lifting bar 8 lifts the force-bearing convex plate 10, so that the water suction box 9 moves up along the slide rail 36. When the lifting bar 8 is separated from the force-bearing convex plate 10, the water suction box 9 falls onto the sludge under the action of its own gravity, so that the water on the sludge passes through the water inlet channel 12 and the one-way valve 13 into the liquid storage chamber 11. The sludge particles are large and cannot enter the water inlet channel 12, thereby achieving the effect of solid-liquid separation. The one-way valve 13 can only allow water to enter the liquid storage chamber 11, and does not allow water to flow back. The water moves so that the water remains in the liquid storage chamber 11. The water level in the liquid storage chamber 11 rises, thereby driving the floating member 15 to move upward. The wedge plate 16 moves upward with the floating member 15. The wedge plate 16 pushes the wedge bar 17 to overcome the elastic force of the elastic member 25 and move forward. When the other end of the lifting bar 8 lifts the force-bearing convex plate 10, the water suction box 9 moves upward along the slide rail 36, and the conveyor belt device 2 continues to transport the sludge to the left. When the permanent magnet 24 moves to the right side of the permanent magnet plate 27, the permanent magnet 24 is attracted by the magnetic attraction of the permanent magnet plate 27, thereby extending the elastic telescopic tube 23. The left end of the elastic telescopic tube 23 extends to the drain plate 29, so that the water flowing out of the elastic telescopic tube 23 can reach the drain plate 29.

[0047] The upward movement of the wedge-shaped bar 17 will lift up one of the spacers 32, so that one of the spacers 32 can overcome the elastic force of the elastic member 33 and move upward to release the blockage of one of the outlet channels 31, so that the flocculant in the storage chamber 35 can pass through the outlet channel 31 and flow to the sludge below, helping the solid particles in the sludge to gather together for subsequent dehydration treatment. The more sludge the suction box 9 falls and contacts, the more water enters the liquid storage chamber 11, and the higher the water level in the liquid storage chamber 11. The greater the upward movement of the floating member 15 and the wedge-shaped plate 16, the greater the forward movement of the wedge-shaped bar 17, and the wedge-shaped bar 17 will push a more forward connecting piece 34. The inner diameter of the outlet channel 31 gradually increases from back to front. When the outlet channel 31 closer to the front is connected, the faster the flocculant flows out, and the more flocculant flows out, so that more sludge can be gathered.

[0048] Then, gear 1 22 continues to move upward, gear 1 22 meshes with rack 26, and gear 1 22 rotates under the drive of rack 26, thereby rotating the knob of knob-type valve 21, and knob-type valve 21 connects water outlet pipe 20, and water in liquid storage chamber 11 passes through water outlet channel 19 and water outlet pipe 20 into elastic telescopic tube 23, and water flows from the left end of elastic telescopic tube 23 to drainage plate 29 and then enters liquid collecting box 28 for recovery.

[0049] The conveyor belt device 2 stops running, the lifting bar 8 continues to rotate to disengage from the force-bearing convex plate 10, the water suction box 9 falls on other parts of the sludge again, the gear 1 22 reverses to make the knob valve 21 re-block the outlet pipe 20, and after the permanent magnet 1 24 loses the magnetic attraction of the permanent magnet plate 27, the elastic telescopic tube 23 shortens under the action of its own elastic force to prevent the elastic telescopic tube 23 and the drainage plate 29 from colliding, and the spacer 32 moves downward and resets under the elastic force of the elastic member 2 33 to re-block the agent outlet channel 31 to prevent waste of flocculant, and the above principle is repeated to perform preliminary dehydration and addition of flocculant on the sludge.

[0050] The sludge is separated from the conveyor belt device 2 from the left side, and the sludge falls into the receiving barrel 37 through the guide of the guide plate 4. The motor 3 55 is turned on, and the motor 3 55 drives the rotating shaft 52, the gear 3 51, and the worm gear 54 to rotate. The worm gear 54 drives the heat-insulating worm 56, the heat-conducting rotating rod 57, the heat-conducting stirring blade 58, and the copper sheet 59 to rotate. The heat-conducting stirring blade 58 stirs the sludge in the receiving barrel 37 to improve the mixing degree of the flocculant and the sludge. The top walls of the adjacent permanent magnets 2 61 are of opposite polarities. When the permanent magnets 2 61 rotate rapidly, they pass through the top walls of all the permanent magnets 2 61. Due to the magnetic field When the induced current flows in the copper sheet 59, Joule heat is generated due to the resistance of the copper sheet 59, causing the copper sheet 59 to heat up. The heat of the copper sheet 59 is transferred to the heat-conducting rotating rod 57 and the heat-conducting stirring blade 58, thereby transferring the heat to the sludge. Increasing the temperature during the mixing process of the sludge and flocculant can promote the hydrolysis and flocculation effect of the flocculant, improve the dewatering performance of the sludge, increase the activity of microorganisms, reduce the content of organic matter in the sludge, and accelerate the dissolution rate of the flocculant, thereby improving the efficiency and effect of the entire sludge treatment.

[0051] Then the sludge enters the screw conveyor assembly 41 through the feed pipe 38, and the gear three 51 drives the screw conveyor assembly 41 to rotate through the gear two 50. The motor two 45 drives the impeller two 46, the transmission belt 47, and the impeller one 44 to rotate. After the speed change of the differential 43, the drum assembly 42 is driven to rotate. The drum assembly 42 and the screw conveyor assembly 41 have the same direction but different rotation speeds. Under the action of the centrifugal force generated by the rotation of the screw conveyor assembly 41, the sludge with relatively large density is thrown onto the inner wall of the drum assembly 42, and the water with relatively small density remains in the screw conveyor assembly 41. The sludge thrown onto the inner wall of the drum assembly 42 is pushed to the mud discharge pipe 49 by the spiral part of the screw conveyor assembly 41 for discharge, and the water is drained through the liquid discharge pipe 48, thereby achieving the effect of solid-liquid separation.

[0052] The present invention can pre-dehydrate the sludge, use the gravity of the water suction box 9 to initially absorb water from the sludge, absorb part of the water, and improve the solid-liquid separation effect of the system. The outlet pipe 20 is automatically driven by the rack 26 to perform drainage operation, and the elastic telescopic tube 23 is automatically extended and retracted by the magnetic force of the permanent magnetic plate 27, so that water can fall onto the drainage plate 29 and will not hinder the lifting of the water suction box 9. The water level in the liquid storage chamber 11 is detected by the floating member 15, so as to automatically detect the amount of sludge below, and automatically add the corresponding dose of flocculant to the sludge to make more sludge agglomerate without wasting too much flocculant. The drive of the motor 3 55 can not only rotate the screw conveyor assembly 41, but also cause the heat-conducting stirring blades 58 to stir the sludge while generating heat, thereby improving the mixing degree of the sludge and the flocculant and improving the subsequent solid-liquid separation effect.

[0053] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
