Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0015] A cooling tower wastewater treatment device for a biomass power generation and heating system, such as Figure 1As shown, it includes a box body 1 with an opening at the top, a box cover 2 is fixedly installed on the top of the box body 1, a rotating motor is fixedly installed on the top of the box cover 2, a rotating shaft 3 is fixedly installed on the bottom end of the output shaft of the rotating motor, the rotating shaft 3 is located in the box body 1, a connecting pipe 4 is fixedly installed on one side of the top of the box cover 2, a drain pipe 5 is connected to the top of one side of the box body 1, a discharge pipe 6 is connected to the bottom end of the other side of the box body 1, a suction pipe 7 is connected to the top of the other side of the box body 1, one end of the suction pipe 7 is fixedly connected to a hose 8, an adjusting mechanism is slidably installed in the box body 1, the adjusting mechanism can adjust the bottom opening height of the hose 8, an L-shaped rod 9 is fixedly installed on one side of the bottom opening of the hose 8, and a water quality turbidity sensor is fixedly installed on the bottom end of the L-shaped rod 9. The coagulant is transported in the pipeline 4, and the wastewater is discharged into the box 1 through the drain pipe 5. The height of the water quality turbidity sensor is lower than the height of the bottom opening of the hose 8. The water suction pipe 7 is connected to the pump body to discharge the wastewater into the box 1, and then the coagulant is transported to the box 1 through the pipeline 4. At the same time, the rotating motor controls the rotating shaft 3 to rotate to mix the coagulant and the wastewater. After mixing, after standing for a period of time, the wastewater is stratified, and the cleaner water is located in the upper layer. At this time, the regulating mechanism controls the bottom opening of the hose 8 to move downward, so that the bottom opening of the hose 8 is located in the upper clean water, and then the clean water is sucked into the hose 8 through the pump body, and then transported. It is sent to the water suction pipe 7 and transported to the next process. The regulating mechanism moves downward step by step. During the downward movement, the water turbidity sensor moves downward synchronously, and the water turbidity sensor detects the clarity and turbidity of the water quality of the next layer of the water absorbed by the hose 8. When the water turbidity sensor detects that the water quality is poor, that is, it exceeds the set value, indicating that the cleaner water has been sucked away, the regulating mechanism controls the bottom opening of the hose 8 to move upward, stops absorbing water, and then opens the valve of the drain pipe 5. The drain pipe 5 discharges the substances on the bottom layer of the box 1. Through the present application, the clean water of the upper layer after wastewater treatment can be discharged, which can be adjusted according to the height of the clean water.

[0016] Specifically, the adjustment mechanism described in this embodiment includes: A placement groove 10, wherein the placement groove 10 is opened on the inner wall of the other side of the box body 1; The screw rod 11 is movably installed in the placement groove 10, the screw rod 11 is threaded with a nut, and the top end of the screw rod 11 passes through the box cover 2; A forward and reverse motor, wherein the forward and reverse motor is fixedly mounted on the top surface of the box cover 2, and the bottom end of the output shaft of the forward and reverse motor is fixedly connected to the top end of the screw rod 11; A connecting rod 12 , one end of which is fixedly connected to the nut, and the other end of which is fixedly connected to one side of the bottom opening of the hose 8 .

[0017] The forward and reverse motor works to control the screw 11 to rotate, so that the nut moves back and forth along the screw 11, driving the connecting rod 12 to move back and forth up and down, and adjusting the bottom end height of the hose 8 to suck out more clean water and prevent the clean water from being discharged with the substances at the bottom of the box body 1.

[0018] Furthermore, the auxiliary stirring mechanism is movably installed at the bottom of the box body 1 described in this embodiment, and the auxiliary stirring mechanism is detachably connected to the rotating shaft 3 through a connecting portion. In order to increase the stirring effect and fully mix the materials at the bottom of the box body 1, after the connecting portion connects the rotating shaft 3 with the auxiliary stirring mechanism, the auxiliary stirring mechanism stirs the materials at the bottom of the box body 1, so that the coagulant and the wastewater are better mixed and the mixing effect is improved.

[0019] Furthermore, the auxiliary stirring mechanism described in this embodiment includes: A reciprocating screw 13, the bottom end of which is movably connected to the inner wall of the bottom end of the box body 1; A nut, which is mounted on the reciprocating screw 13; Two limiting rods 14 are respectively located at two sides of the nut and are respectively fixedly connected to the nut. The opposite ends of the two limiting rods 14 are respectively in contact with the inner walls of the box body 1 on both sides.

[0020] After the connecting part is connected to the reciprocating screw 13, the reciprocating screw 13 is driven to rotate, and the nut moves up and down along the reciprocating screw 13, driving the two limiting rods 14 to move up and down. The two limiting rods 14 stir the material at the bottom of the box body 1 to mix the material with the coagulant.

[0021] Furthermore, the connection part of this embodiment includes: A waterproof telescopic rod 15, wherein the waterproof telescopic rod 15 is fixedly mounted on the bottom end of the rotating shaft 3; An insert block 16, wherein the insert block 16 is fixedly mounted on the bottom end of the movable end of the waterproof telescopic rod 15; The round block 17 is fixedly mounted on the top of the reciprocating screw 13. A slot is provided on the top surface of the round block 17, and the insert block 16 can be inserted into the slot.

[0022] One side of the bottom surface of the plug block 16 and one side of the bottom surface of the slot are both inlaid with locators. The rotating shaft 3 drives the waterproof telescopic rod 15 and the plug block 16 to rotate slowly. When the two locators are located on the same vertical central axis, the two locator signals are in contact. At this time, the rotating shaft 3 stops rotating, and the waterproof telescopic rod 15 is extended to insert the plug block 16 into the slot. After the plug block 16 is inserted, the rotating shaft 3 starts to rotate, driving the reciprocating screw 13 to rotate, and the bottom material in the box body 1 is stirred through the limiting rod 14.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
