Description

Technical Field

[0001] The present invention relates to the technical field of water ecological restoration, and specifically relates to a sludge treatment device and a usage method for water ecological restoration. Background Art

[0002] Water ecological restoration refers to the process of restoring a damaged or degraded water body ecosystem to a healthy and stable state through ecological principles and technical means. Its core goal is to reconstruct the biodiversity, self-purification ability and ecological balance of the water body, and ultimately achieve the virtuous cycle and sustainable development of the water ecological system.

[0003] Currently, in the process of water ecological restoration, not only the polluted water source needs to be treated, but also the ecological environment of the sludge at the bottom of the lake will be damaged and polluted because the sludge has been in contact with the water source for a long time. Therefore, the restoration of the sludge is also crucial. In the prior art, when repairing the sludge, generally, a repair agent is sprayed into the sludge and then the sludge is agitated to make the repair agent evenly mixed with the sludge. However, when spraying the repair agent, the repair agent can only be sprayed onto the end face of the sludge and cannot penetrate into the interior of the sludge. Therefore, it takes a lot of time to agitate the sludge to make the repair agent evenly mixed with the sludge, resulting in a low repair efficiency of the sludge. For this reason, we propose a sludge treatment device and a usage method for water ecological restoration. Summary of the Invention

[0050] Working principle: When repairing the sludge, first dry the collected sludge, then grind the dried sludge to pulverize it, which facilitates the contact and mixing of the repair agent with the sludge. After that, convey the pulverized sludge to the repair tank 1. Then start the pump body 18. Through the action of the pump body 18, convey the repair agent inside the repair agent tank 17 to the infusion pipe 19 through the feed pipe 51, and then convey the repair agent to the liquid inlet pipe 20 through the infusion pipe 19. Then convey the repair agent into the feed pipe 11 through the sleeve 22 and the feed hole 15. After that, the repair agent will be conveyed into multiple groups of connecting pipes 13 through the shunt pipe 12, and finally enter multiple groups of stirring pipes 3 through the connecting pipe 14 and be discharged through the through hole 4. During this process, start the motor 30 to drive the drive shaft 31 to rotate. When the drive shaft 31 rotates, it will drive the drive shaft 31 to rotate. Through the rotation of the drive shaft 31, the first flat gear 32 will be driven to rotate. Through the rotation of the first flat gear 32, the second flat gear 33 will be driven to rotate, thus driving the feed pipe 11 to rotate. Furthermore, through the rotation of the feed pipe 11, the shunt pipe 12 will be driven to rotate, thus driving multiple groups of connecting pipes 13 to rotate, so that multiple groups of connecting pipes 14 drive multiple groups of stirring pipes 3 to rotate inside the repair tank 1. Through the action of the stirring pipes 3, the sludge is stirred, improving the mixing efficiency of the repair agent and the sludge; During this process, the rotation of the drive shaft 31 will also drive the wind wheel 26 to rotate. The wind force generated by the rotation of the wind wheel 26 will be conveyed to the inside of the sleeve 22 through the air delivery pipe 27 and the air inlet pipe 28. Through the action of the wind force, the conveying of the repair agent is pressurized, thus improving the discharging speed of the repair agent, and further improving the mixing efficiency of the repair agent and the sludge;

[0051] After the repair is completed, the pump body 18 stops starting. At this time, the motor 30 continues to rotate, so that the drive shaft 31 drives the wind wheel 26 to rotate. The wind force generated when the wind wheel 26 rotates will be conveyed to the inside of the sleeve 22 through the air delivery pipe 27 and the air inlet pipe 28, then enter the feed pipe 11 through the feed hole 15, and then be conveyed to the connecting pipe 14 through the shunt pipe 12 and the connecting pipe 13. Then, the wind force is conveyed to the inside of the stirring pipe 3 through the connecting pipe 14 and finally discharged through the through hole 4. Through the action of the wind force, the sludge is air-dried. During this process, the rotation of the drive shaft 31 will continue to drive the first flat gear 32 to rotate, and then the second flat gear 33 will be driven to rotate. Thus, through the rotation of the second flat gear 33, the feed pipe 11 and the shunt pipe 12 are driven to rotate, so that the connecting pipe 13 drives the connecting pipe 14 to rotate. Through the rotation of the connecting pipe 14, the stirring pipe 3 rotates inside the repair tank 1, accelerating the air-drying efficiency;

[0052] After air drying, control the motor 30 to reverse. The reverse rotation of the motor 30 drives the drive shaft 31 to reverse, so that the driving wheel 34 reverses. Then, the belt 35 drives the driven wheel 36 to reverse. Therefore, the reverse rotation of the driven wheel 36 causes the transmission shaft 44 to drive the ratchet gear 45 to reverse. At this time, since the reverse rotation of the ratchet gear 45 meshes with the ratchet pawl 47, the rotating plate 46 rotates. The rotation of the rotating plate 46 will drive the rotating shaft 40 to rotate, thus driving the reciprocating lead screw 42 to rotate. The rotation of the reciprocating lead screw 42 causes the threaded sleeve 43 to reciprocate up and down. The up and down reciprocating movement of the threaded sleeve 43 will cause the push rod 38 to drive the push block 39 to reciprocate up and down. Therefore, the sludge inside the repair tank 1 is pushed by the up and down reciprocating movement of the push block 39, avoiding the accumulation of sludge affecting the discharge of sludge. And in this process, since the drive shaft 31 rotates, the first spur gear 32 drives the second spur gear 33 to rotate. Therefore, the feed pipe 11 drives the shunt pipe 12 to rotate, and further makes the connecting pipe 13 drive the communicating pipe 14 to rotate, so that the stirring pipe 3 rotates inside the repair tank 1. Through the stirring action of the stirring pipe 3 on the sludge, the discharge of sludge is further accelerated;

[0053] It should be noted that: the setting of the first one-way valve 21 can only transport the repair agent into the liquid inlet pipe 20, and the setting of the second one-way valve 29 can transport wind into the air inlet pipe 28. Therefore, during the drying process, the wind will not be discharged through the liquid inlet pipe 20, but will only enter the repair tank 1 and blow towards the sludge. The setting of the second one-way valve 29 prevents the repair agent from being discharged through the air inlet pipe 28;

[0054] It is also worth noting that: during the sludge treatment process, the motor 30 rotates forward to drive the drive shaft 31 to rotate forward, and then the driving wheel 34 rotates forward. Therefore, the belt 35 drives the driven wheel 36 to rotate forward. At this time, since the forward rotation of the driven wheel 36 will drive the transmission shaft 44 and the ratchet gear 45 to rotate forward. In this state, the ratchet gear 45 will disengage from the ratchet pawl 47, so it cannot drive the rotating plate 46 to rotate. At this time, the reciprocating lead screw 42 will not rotate, that is, in the sludge treatment state, the push block 39 will not move.

[0055] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
