[0028] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

[0029] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0030] Embodiment 1, an industrial wastewater treatment equipment, comprises a tank body 1, a water inlet 2 opened on the tank body 1, a stirring shaft 3 installed inside the tank body 1 and a stirring blade 4 fixedly installed on the stirring shaft 3, the stirring shaft 3 is driven by a driving device, and the driving device is driven by a driving motor. When in use, industrial wastewater is poured into the tank body 1 through the water inlet 2, and the driving motor drives the stirring shaft 3 to rotate, thereby driving the stirring blade 4 to rotate, and the industrial wastewater inside the tank body 1 is stirred, a dispersion plate 5 is fixedly installed on the stirring shaft 3, the dispersion plate 5 is located above the water inlet 2, an annular material discharge trough 6 is opened on the dispersion plate 5, and a plurality of dispersion holes 7 are evenly opened at the bottom of the material discharge trough 6, a top cover 8 is detachably connected to the top of the tank body 1, and at least one distribution plate 9 is installed on the top cover 8, and the distribution plate 9 is used to distribute the wastewater falling on the material discharge trough 6. The medicine powder inside the trough 6 is evenly dispersed, and the medicine powder is pushed to fall into the tank body 1 through the dispersion holes 7, so that it is fully integrated with the industrial wastewater. When the distribution plate 9 is set to one, the medicine feeding efficiency is relatively slow and the medicine feeding is relatively concentrated. Therefore, in the present embodiment, the distribution plate 9 is set to two, and the two distribution plates 9 are arranged at intervals. The lower end surface of the distribution plate 9 fits the bottom of the feeding trough 6. A feeding device is installed on the top of the tank body 1. The feeding device is used to transport the material to the feeding trough 6. The feeding device can be used to install a feeding box on the top cover 8, open a feeding hole on the top cover 8, and place medicine powder inside the feeding box, so that the medicine powder inside the feeding box is slowly fed into the inside of the feeding trough 6; a auger device can also be used to transport the medicine powder to the top of the top cover 8 through the auger, and the medicine powder is slowly dropped onto the dispersion plate 5 through the feeding hole opened on the top cover 8.

[0031] A connecting rod is fixedly connected to the upper end of the distribution plate 9, and the connecting rod is slidably connected to the top cover 8. A sliding hole is opened on the top cover 8, and the connecting rod passes through the sliding hole so that the connecting rod is slidably connected inside the sliding hole. A first elastic member is connected between the distribution plate 9 and the top of the top cover 8. The first elastic member can be a metal spring, an elastic rubber rope or other elastic parts. In this embodiment, the first elastic member is a tension spring. When in use, under the action of the tension spring, the distribution plate 9 is pulled toward the inside of the discharge trough 6 to make the distribution plate 9 and the discharge trough 6 fit together.

[0032] During the specific implementation of this embodiment, industrial wastewater is poured into the tank body 1 through the water inlet 2, and the powder is put into the feed chute 6. The driving motor drives the stirring shaft 3 to rotate, thereby driving the stirring blades 4 to rotate, and the industrial wastewater in the tank body 1 is stirred. When the stirring shaft 3 rotates, it drives the dispersion plate 5 to rotate. After the powder falls into the feed chute 6, the dispersion plate 5 rotates and drives the powder that falls into the feed chute 6 to rotate to the position on the distribution plate 9. The distribution plate 9 pushes the powder to disperse in the feed chute 6, and at the same time pushes the powder to the top of the dispersion hole 7 through the distribution plate 9. Then the distribution plate 9 pushes the powder into the tank body 1 through the dispersion hole 7, and contacts with the industrial wastewater. The powder is stirred by the stirring blades 4 to make the powder and the industrial wastewater fully contact.

[0033] Embodiment 2, on the basis of embodiment 1, the distribution plate 9 is set to be V-shaped. When installing, the sharp end of the distribution plate 9 is installed facing the direction of rotation of the stirring shaft 3, and the powder falls into the middle position of the feeding trough 6. When the dispersion plate 5 rotates, the powder inside the feeding trough 6 contacts the sharp end of the distribution plate 9, and the powder is evenly dispersed in two directions along the two oblique sides of the distribution plate 9 through the sharp end of the distribution plate 9, so that the distribution plate 9 makes the powder flow out of the tank body 1 through the dispersion hole 7, so that the powder is scattered more dispersedly.

[0034] Embodiment 3, on the basis of embodiment 2, when in use, the medicine powder is pushed through the dispersion hole 7 by the distribution plate 9, and the medicine powder cannot pass through the dispersion hole 7 well, so this embodiment provides an auxiliary discharge structure to solve the above problem. Specifically, a plurality of evenly distributed dispersion grooves 10 are opened at one end of the distribution plate 9 close to the dispersing disk 5. When in use, the medicine powder inside the discharge chute 6 contacts the sharp corner end of the distribution plate 9, and a part of the medicine powder is pushed to both sides through the sharp corner end of the distribution plate 9, and is scattered into the tank body 1 through the dispersion hole 7 and merged with the wastewater, and the other part passes through the dispersion groove 10.

[0035] A uniform feeding brush 11 is installed on the distribution plate 9. The uniform feeding brush 11 is used to disperse the material and push it out from the dispersion hole 7. When in use, the uniform feeding brush 11 cleans the powder passing through the dispersion groove 10, so that the powder passes through the dispersion hole 7 inside the feeding groove 6 evenly, making the feeding more uniform.

[0036] Embodiment 4. On the basis of embodiment 3, this embodiment provides a brush driving structure, so as to realize reciprocating sweeping of the medicine powder passing through the dispersion groove 10, so that it can be evenly scattered into the interior of the tank body 1 through the dispersion holes 7. Specifically, the uniform feeding brush 11 is slidably connected to the distribution plate 9, and a mounting plate is fixedly installed above the distribution plate 9. A slide groove is provided on the mounting plate, and a sliding block slidably connected to the inside of the slide groove is installed on the uniform feeding brush 11, so that the uniform feeding brush 11 slides on the mounting plate. A pushing structure for pushing the uniform feeding brush 11 to slide on the distribution plate 9 is provided on the dispersion disk 5. The pushing structure can use a reciprocating hydraulic cylinder or a pneumatic cylinder to push the uniform feeding brush 11 to slide on the mounting plate.

[0037] The present embodiment provides another driving structure. Specifically, the driving structure includes a driving disk 12 fixedly connected to the stirring shaft 3, a plurality of evenly distributed arc-shaped driving plates 13 are fixedly connected to the driving disk 12, an arc-shaped matching plate 14 matching the arc-shaped driving plate 13 is fixedly connected to one end of the uniform feeding brush 11, and a second elastic member is installed between the uniform feeding brush 11 and the distribution plate 9. The second elastic member can be a metal spring, an elastic rubber rope or other elastic parts. In the present embodiment, the second elastic member is a compression spring. When in use, the compression spring pushes the uniform feeding brush 11 toward the driving disk 12, so that the arc-shaped matching plate 14 contacts the arc-shaped driving plate 13.

[0038] During the implementation of this embodiment, the stirring shaft 3 rotates, driving the driving disk 12 to rotate. When the arc-shaped push plate 13 and the arc-shaped matching plate 14 are in contact, the arc-shaped push plate 13 pushes the uniform feeding brush 11 in the direction away from the driving disk 12 through the arc-shaped matching plate 14. When the arc-shaped push plate 13 and the arc-shaped matching plate 14 are out of contact, the compression spring pushes the uniform feeding brush 11 in the direction close to the driving disk 12, thereby reciprocating to evenly disperse the powder inside the feeding chute 6 to the position of the dispersion hole 7, so that the powder passes through the dispersion hole 7 and is scattered into the inside of the tank body 1.

[0039] Embodiment 5, on the basis of embodiment 1, when adding medicine powder into the wastewater, it is not easy to control the metering of the added medicine powder, so this embodiment provides a feeding device to solve the above problem, specifically, the feeding device includes a material box 15 fixedly installed on the upper end of the top cover 8, the bottom of the material box 15 is provided with a discharge port 16, the top cover 8 is provided with a through hole 17 connected to the discharge port 16, the lower end of the top cover 8 is fixedly connected with a conveying trough 18 located below the through hole 17, when in use, the medicine powder is added into the material box 15, the medicine powder enters the conveying trough 18 through the discharge port 16 and the through hole 17, the medicine powder falls between the spiral blades 20, the conveying trough 18 is rotatably connected with a drive shaft 19, and the drive shaft 19 is connected to the conveying trough 18. 9 is fixedly connected with a spiral blade 20, and the driving shaft 19 is driven by a conveying driving device. The driving device is driven by a stepper motor, and the stepper motor is connected to a control module. When in use, the control module controls the stepper motor to rotate a certain angle and then stop. A discharge port 21 is opened at one end of the conveying trough 18, and the discharge port 21 is located above the discharge trough 6. When in use, the powder is loaded into the material box 15, and the stepper motor is started. The rotation of the stepper motor drives the driving shaft 19 to rotate, and the rotation of the driving shaft 19 drives the spiral blades 20 to rotate synchronously, pushing the powder between the spiral blades 20 toward the discharge port 21, so that the powder inside the material box 15 falls quantitatively from the discharge port 21 into the inside of the discharge trough 6.

[0040] Embodiment 6, on the basis of embodiment 5, when in use, when the powder between the spiral blades 20 is pushed in the direction close to the discharge port 21, the powder between the spiral blades 20 does not fill the gaps between the spiral blades 20. Therefore, this embodiment provides a powder replenishing structure to solve the above problem. Specifically, a supplementary feeding trough 22 is provided at the bottom of the material box 15, and a supplementary discharge trough 23 connected to the supplementary feeding trough 22 is provided on the top cover 8. The supplementary discharge trough 23 is located above the conveying trough 18. When in use, the powder inside the material box 15 falls between the spiral blades 20 through the supplementary feeding trough 22 and the supplementary discharge trough 23, thereby replenishing the powder between the spiral blades 20.

[0041] Embodiment 7, on the basis of embodiment 5, the medicine powder is not easy to slide into the discharge port 16, so this embodiment provides a guide structure. Specifically, a guide block 24 is obliquely arranged inside the material box 15, and the cross-section of the guide block 24 is set to be triangular. When in use, the medicine powder inside the material box 15 is guided by the inclined surface of the guide block 24 and falls into the discharge port 16, and enters the conveying trough 18 through the discharge port 16.

[0042] When implementing it specifically,

[0043] The medicine powder is loaded into the material box 15, and the stepper motor is started. The rotation of the stepper motor drives the driving shaft 19 to rotate, and the rotation of the driving shaft 19 drives the spiral blades 20 to rotate synchronously, pushing the medicine powder between the spiral blades 20 toward the discharge port 21, so that the medicine powder inside the material box 15 falls quantitatively from the discharge port 21 into the discharge chute 6;

[0044] Industrial wastewater is poured into the tank body 1 through the water inlet 2, and the driving motor drives the stirring shaft 3 to rotate, thereby driving the stirring blades 4 to rotate, and the industrial wastewater in the tank body 1 is stirred. When the stirring shaft 3 rotates, it drives the dispersion plate 5 to rotate. After the medicine powder falls into the lower feeding trough 6, the dispersion plate 5 rotates and drives the medicine powder that falls into the lower feeding trough 6 to rotate to the position on the distribution plate 9. The distribution plate 9 pushes the medicine powder to be dispersed in the lower feeding trough 6, and at the same time, the medicine powder is pushed to the top of the dispersion hole 7 through the distribution plate 9. Then, the distribution plate 9 pushes the medicine powder into the tank body 1 through the dispersion hole 7, and contacts with the industrial wastewater. The powder is stirred by the stirring blades 4, so that the medicine powder and the industrial wastewater are fully contacted.

[0045] The stirring shaft 3 rotates, driving the driving disk 12 to rotate. When the arc-shaped pushing plate 13 and the arc-shaped matching plate 14 are in contact, the arc-shaped pushing plate 13 pushes the uniform feeding brush 11 in the direction away from the driving disk 12 through the arc-shaped matching plate 14. When the arc-shaped pushing plate 13 and the arc-shaped matching plate 14 are out of contact, the compression spring pushes the uniform feeding brush 11 in the direction close to the driving disk 12, thereby reciprocating to evenly disperse the powder inside the feeding chute 6 to the position of the dispersion hole 7, so that the powder passes through the dispersion hole 7 and scatters into the inside of the tank body 1.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
