[0043] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0044] Example 1

[0045] Reference Figure 1-Figure 2 , a wastewater treatment device for a thermal power plant is provided, comprising a tank body 100, a water inlet 101 is provided on the top, a water outlet 102 is provided on the bottom, and a water storage part 200 is provided inside the tank body;

[0046] The stirring part 300 is rotatably disposed inside the water storage part 200; wherein the stirring part 300 can stir the water in the water storage part 200;

[0047] The top of the tank body 100 is semicircular and the bottom is inverted cone shape. The water storage part 200 is fixedly arranged at the top of the tank body 100. The water inlet 101 penetrates into the water storage part 200. When the wastewater enters the tank body 100 through the water inlet 101, the wastewater is stored in the water storage part 200. At the same time, the stirring part 300 stirs the wastewater in the water storage part 200 to mix the flocculant with the wastewater.

[0048] Furthermore, the water storage part 200 includes a cylinder 201 disposed at the top of the tank body 100 and a plurality of drainage pipes 202 disposed at the bottom of the cylinder 201;

[0049] The cylinder 201 is fixedly arranged at the top of the tank 100, and multiple sets of drainage pipes 202 are fixedly arranged at the bottom thereof. The water inlet 101 is connected to the top of the cylinder 201. Since the water inflow of the cylinder 201 is large and the diameter of the drainage pipe 202 is small, the water inflow of the cylinder 201 is greater than the drainage, and the wastewater is stored in the cylinder 201.

[0050] The stirring part 300 includes a long shaft 301 rotatably arranged in the cylinder 201, both ends of the long shaft 301 extend out of the cylinder 201 and are rotatably connected to the side wall of the tank body 100, one end of the long shaft 301 extends out of the tank body 100 and is connected to an external driving mechanism, and a plurality of groups of stirring blades 302 are radially arranged on the long shaft 301. When the wastewater is accumulated in the cylinder 201, the driving mechanism drives the long shaft 301 to rotate. When the long shaft 301 rotates, the stirring blades 302 stir and mix the wastewater and flocculant in the cylinder 201, and the mixed wastewater flows to the bottom of the tank body 100 through the drain pipe 202, and is discharged from the water outlet 102 to enter the next treatment link.

[0051] The provision of the water storage part 200 prolongs the residence time of the wastewater in the tank body 100, so that the stirring part 300 can fully stir the wastewater and the flocculant, thereby improving the wastewater treatment effect.

[0052] Example 2

[0053] In the above embodiment, when the stirring part 300 is stirring, a small amount of flocculant will still not be dissolved and will settle at the bottom of the cylinder 201, and the flocculant cannot effectively play its role.

[0054] Reference Figure 1-Figure 5 , this embodiment is different from the first embodiment in that: it also includes a lifting component 400, which includes an adjustment component 401, and the adjustment component 401 is slidably arranged in the tank body 100; wherein the adjustment component 401 can control the opening and closing of the drain pipe 202;

[0055] By adjusting the sliding of the component 401, the position of the component 401 in the drain pipe 202 is moved, and then the opening and closing of the drain pipe 202 are controlled. By closing the drain pipe 202, wastewater can be accumulated in the cylinder 201 when the water intake is small, thereby extending the time the wastewater stays in the tank body 100.

[0056] Furthermore, the inner walls of both sides of the tank body 100 are fixedly provided with a limit assembly 402, which is connected to the end of the adjustment assembly 401; wherein the limit assembly 402 guides the adjustment assembly 401;

[0057] The regulating assembly 401 includes a long rod 401a disposed in the tank body 100, and a plurality of fixed rods 401b are fixedly disposed on the top of the long rod 401a, and a ball 401c is fixedly disposed on the top of the plurality of fixed rods 401b. In the present embodiment, the drain pipe 202 is a trumpet-shaped one with a large diameter at the bottom and a small diameter at the top. The diameter of the ball 401c corresponds to the inner diameter of the upper end of the drain pipe 202. When the ball 401c is located at the upper end of the drain pipe 202, it can fit with the inner wall of the drain pipe 202, thereby closing the drain pipe 202, and waste water is accumulated in the cylinder 201. When the ball 401c moves downward and leaves the drain pipe 202, the drain pipe 202 is opened, and the waste water in the cylinder 201 can be discharged.

[0058] The limiting assembly 402 includes side plates 402a fixedly provided at both ends of the long rod 401a, and limiting strips 402b are fixedly provided on the inner walls on both sides of the tank body 100, and the side plates 402a are slidably provided in the limiting strips 402b, thereby enabling the adjusting assembly 401 to be slidably provided in the tank body 100. At the same time, the limiting strips 402b cooperate with the side plates 402a to limit the moving direction of the adjusting assembly 401, thereby ensuring that the multiple groups of balls 401c can correspond one-to-one with the multiple groups of drainage pipes 202.

[0059] Furthermore, a fixing member 403 is provided on the limiting assembly 402; a guide member 404 is provided on the stirring portion 300, and the fixing member 403 extends into the guide member 404;

[0060] When the fixing member 403 moves in the guide member 404, it can drive the adjusting member 401 to move through the limiting member 402;

[0061] The two sets of side plates 402a are fixed with fixing parts 403 on the corresponding sides. A guide part 404 is fixedly provided on the outer side of the long axis 301 in the tank body 100. The guide part 404 is disc-shaped. A groove corresponding to the fixing part 403 is opened on one side of the guide part 404. Then, the fixing part 403 is inserted into the guide part 404. The insertion of the fixing part 403 and the guide part 404 can limit the position of the adjustment component 401.

[0062] The guide member 404 can rotate along with the long axis 301. When the long axis 301 rotates, the fixing member 403 moves in the groove of the guide member 404. Since the limiting assembly 402 limits the adjusting assembly 401, the movement of the fixing member 403 causes the adjusting assembly 401 to move up and down, so that the adjusting assembly 401 is controlled to slide upward or downward, thereby opening and closing the drain pipe 202.

[0063] Furthermore, the guide member 404 is provided with a first arc groove 404a; when the fixing member 403 is located in the first arc groove 404a, the regulating assembly 401 closes the drain pipe 202;

[0064] The guide member 404 is provided with a second arc groove 404b connected to the first arc groove 404a; when the fixing member 403 is located in the second arc groove, the drain pipe 202 is opened;

[0065] In this embodiment, the fixing member 403 is a cylinder, and a first arc groove 404a is formed in the guide member 404. The end of the first arc groove 404a is connected to the second arc groove 404b. The centers of the first arc groove 404a and the second arc groove 404b are both set to the axis of the long axis 301. The radius of the second arc groove 404b is greater than the radius of the first arc groove 404a. The first arc groove 404a and the second arc groove 404b are connected by an oblique groove, so that when the long rod 401a rotates, the fixing member 403 can move from the first arc groove 404a to the second arc groove 404b.

[0066] In the initial state, the fixing member 403 is located in the first arc groove 404a, the ball 401c is located at the upper end of the drain pipe 202, the drain pipe 202 is in a closed state, the wastewater enters the cylinder 201 through the water inlet 101, the stirring part 300 rotates to stir and mix the wastewater and the flocculant, and the long shaft 301 rotates to drive the guide member 404 to rotate synchronously. When the guide member 404 rotates in the first direction, the first direction is as shown in FIG. Figure 5In the direction indicated by the middle arrow, the fixing member 403 is continuously in the first arc groove 404a, so that the drain pipe 202 can remain in a closed state, and a certain amount of waste water can be accumulated in the cylinder 201. During the rotation of the long axis 301, the fixing member 403 gradually enters the second arc groove 404b from the first arc groove 404a. Since the radius of the second arc groove 404b is greater than that of the first arc groove 404a, and the limit assembly 402 guides the adjustment assembly 401, when the fixing member 403 is located in the second arc groove 404b, the adjustment assembly 401 moves downward, thereby driving the multiple groups of balls 401c to move out of the drain pipe 202, and the drain pipe 202 is fully opened, and the waste water in the cylinder 201 can be discharged.

[0067] Furthermore, a third arc groove 404c is provided between the first arc groove 404a and the second arc groove 404b; when the fixing member 403 is located in the third arc groove 404c, the water in the cylinder 201 is discharged in a jet-like manner through the drain pipe 202;

[0068] The end of the first arc groove 404a away from the second arc groove 404b is connected to the third arc groove 404c, the radius of the third arc groove 404c is smaller than the second arc groove 404b, and larger than the first arc groove 404a, and the third arc groove 404c is connected to the ends of the second arc groove 404b and the first arc groove 404a through the oblique groove, so that when the fixing member 403 is located in the third arc groove 404c, the ball 401c is located in the middle position inside the drain pipe 202. At this time, since there is a narrow drainage gap between the periphery of the ball 401c and the inner wall of the drain pipe 202, and a large amount of water is gathered in the cylinder 201, the water in the cylinder 201 is discharged from the drain pipe 202 in a jet shape, so that the flocculant precipitated at the bottom can be evenly mixed with the wastewater, and the flocculant is fully dissolved;

[0069] During the rotation of the long shaft 301, the order of the movement of the fixing member 403 in the guide member 404 is the first arc groove 404a, the second arc groove 404b, and the third arc groove 404c. When the fixing member 403 is located in the first arc groove 404a, waste water accumulates in the cylinder 201. When the fixing member 403 is located in the second arc groove 404b, the drain pipe 202 is fully opened, and then the tiny flocs accumulated at the bottom of the cylinder 201 are discharged to avoid clogging of the drain pipe 202. When the fixing key is located in the third arc groove 404c, the waste water is discharged from the cylinder 201 in a jet shape.

[0070] Then, by setting the lifting component 400, the flocculant is fully dissolved to prevent the flocculant from settling at the bottom of the cylinder 201, so that the function of the flocculant is fully exerted and the wastewater treatment effect is improved.

[0071] The rest of the structure is the same as that of Example 1.

[0072] Example 3

[0073] In the above embodiment, the flocculant needs to be added into the device manually, and the time of adding the agent and the amount of powder added are not easy to control.

[0074] Reference Figure 1-Figure 8 , this embodiment is different from the above embodiments in that: a drug inlet 103 is provided on the top of the tank body 100, and the top of the drug inlet 103 is connected to the material storage mechanism;

[0075] A drug inlet 103 is fixedly provided on the top of the tank body 100 , the top of the drug inlet 103 is connected to a storage mechanism, and the storage mechanism can store drug powder. The bottom of the drug inlet 103 is connected to the top of the cylinder 201 , and the drug powder enters the cylinder 201 through the drug inlet 103 .

[0076] Furthermore, a rotating part 500 is provided in the medicine inlet 103, and the rotating part 500 can pour the medicine powder into the water storage part 200;

[0077] In this embodiment, the medicine inlet 103 is in the shape of a sphere 401c as a whole, and a connecting tube is fixedly connected to the top, and the connecting tube is connected to the storage mechanism. The rotating part 500 includes a rotating shaft 501 rotatably connected to the medicine inlet 103, and multiple groups of rotating plates 502 are equidistantly arranged axially on the outer side of the rotating shaft 501. The rotating plates 502 are semicircular arc-shaped, so that their edges fit the inner wall of the medicine inlet 103. The medicine powder enters between the multiple groups of rotating plates 502 through the connecting tube at the top. The diameter of the opening between the cylinder 201 and the medicine inlet 103 is smaller than the distance between the ends of the two groups of rotating plates 502, so that the medicine powder between the two groups of rotating plates 502 is one portion and added into the cylinder 201;

[0078] Since the powder will fall into the cylinder 201 when the rotating plate 502 passes through the opening, Figure 7 There is medicine powder between the multiple groups of rotating plates 502 in area a, but there is no medicine powder between the multiple groups of rotating plates 502 in area b. Due to the weight difference between area a and area b, the rotating shaft 501 can continue to rotate in the second direction. The second direction is Figure 7 The rotating plate 502 can automatically rotate in the direction indicated by the middle arrow to release the powder into the cylinder 201 .

[0079] Furthermore, a blocking member 600 is provided inside the cylinder 201; the blocking member 600 can resist the rotating part 500, and when the stirring part 300 rotates, it can resist the blocking member 600 away from the rotating part 500, thereby controlling the frequency of the rotating spraying;

[0080] The blocking component 600 includes a fixing frame 601 fixedly arranged at the top of the cylinder 201, the fixing frame 601 is located at the bottom of the connection between the medicine inlet 103 and the cylinder 201, and a sliding member 602 is provided in the fixing frame 601, and the sliding member 602 includes a convex block 602a slidably arranged in the fixing frame 601, and the two sides of the convex block 602a are attached to the inner wall of the fixing frame 601, and a short plate 602b is fixedly arranged at one end of the convex block 602a, and the bottom of the short plate 602b is fixed. A baffle 602c is provided, and the baffle 602c extends out of the limiting cylinder 601a. ​​A guide groove 601b corresponding to the baffle 602c is provided at the bottom of the limiting cylinder 601a. ​​In this embodiment, a plurality of groups of stirring blades 302 arranged in the same radial direction along the long axis 301 are connected to a group of long plates 303, and the baffle 602c is located on the rotation track of the long plates 303, so that the baffle 602c can contact the baffle 602c during the rotation process, thereby driving the protrusion 602a to slide;

[0081] The top of the fixed frame 601 is connected to the limiting cylinder 601a, and a slider 603 is slidably provided in the limiting cylinder 601a, and the bottom end of the slider 603 contacts the top of the sliding member 602. When the slider 603 is located at the top of the protrusion 602a, the protrusion 602a moves out of the cylinder 201 and extends into the medicine inlet 103, so that it can prevent the rotating plate 502 from rotating. A spring 604 is provided in the fixed frame 601, and the spring 604 is located between the inner wall of the fixed frame 601 and the protrusion 602a. Limiting columns 602d are fixedly provided on both sides of the short plate 602b. Straight grooves 601c and oblique grooves 601d corresponding to the limiting columns 602d are opened on both sides of the fixed frame 601, and the straight grooves 601c are connected with the oblique grooves 601d.

[0082] In the initial state, the spring 604 contacts the protrusion 602a, so that the end of the short plate 602b contacts the side wall of the fixing frame 601. At this time, the slider 603 is located above the protrusion 602a, and the upper end of the slider 603 is located in the medicine inlet 103. The rotating part 500 is blocked and cannot rotate. The limiting column 602d is located at the end of the straight groove 601c. When the stirring part 300 rotates, the long plate 303 gradually moves to contact the baffle 602c, and then pushes the protrusion 602a away from the slider 603, so that the slider 603 drops and separates from the rotating plate 502. The rotating plate 502 rotates in the second direction under the weight of the powder. At this time, the powder between the two groups of rotating plates 502 at the lower end of the A area is poured into the cylinder 201;

[0083] After the slider 603 slides downward, the short plate 602b is pushed to correspond to its bottom end, and the long plate 303 pushes the limiting column 602d and the straight groove 601c into the inclined groove 601d, so that the short plate 602b rises, and then the baffle 602c is separated from the long plate 303. During this process, the top of the short plate 602b always corresponds to the bottom end of the slider 603. After the baffle 602c is separated from the long plate 303, the spring 604 pushes the protrusion 602a to reset, and the protrusion 602a again resists the slider 603 to rise. The slider 603 prevents the rear rotating plate 502 from continuing to rotate. At the same time, after the long plate 303 is separated from the baffle 602c, it scatters the poured powder and then disperses the powder in the cylinder 201.

[0084] By setting the blocking component 600 and the rotating part 500, the medicine powder can be poured into the cylinder 201 evenly, regularly and quantitatively to ensure the use effect of the flocculant.

[0085] The rest of the structure is the same as that of Example 2.
